What do you need to pay attention to when choosing a door lock?

If you choose a door lock, then its anti-theft performance requirements are relatively high. At present, good door anti-theft locks mostly use steel as the main material (villa door locks can be made of zinc alloy or copper, with various styles and changeable textures), and steel has higher hardness and solidity than cast iron. The indoor door lock is mainly private, with decorative functions, reflecting a kind of home quality.

Since it is opened more often, it must be of good quality. The first is the wear resistance, which is related to the material of the door lock. When purchasing, ask the dealer what kind of material it is made of.

Due to frequent use, the feel of the door lock is also important, and the feel of the door lock is determined by the spring. Some locks have bad springs, so it is easy to cause the handle to sag, thus ending the life of the door lock. When purchasing, you should try the toughness of the door lock spring, the feel brought by a good spring is very soft, not too soft and not too hard.

In the process of purchasing, it is also necessary to look at the plating of the door lock, that is, to consider whether the handle of the door lock will fade. Generally speaking, the protective layer, that is, the plating of a good door lock, will not be easily oxidized and worn out. The plating of the door lock handle is related to the overall aesthetics of the room, so this should not be overlooked.

First of all, to understand the material of the door lock, the door lock material on the market is mainly divided into zinc alloy, stainless steel and copper! Zinc alloy has good manufacturing performance, and can die-cast various precision parts with complex shapes and thin walls, and has a smooth surface in the morning. Surface treatment available:

Plating, spraying, painting and other processes! No iron absorption, no corrosion, no mold sticking during melting and die casting! It has very good mechanical properties and wear resistance at room temperature.

Good melting point, melted at 385, easy die-casting! Compared with stainless steel locks and copper locks, zinc alloy has the following advantages: high cost performance, product technology is particularly prominent, and it shows unique advantages in decorative effect.

The specific performance of the process is as follows: (1) casting process; (2) machining technology; (3) Surface treatment process; Good economy: Compared with low-end aluminum locks and iron locks, its quality and performance are very prominent.

Stainless steel series: From the perspective of durability, the best material should be stainless steel, especially when used as a surface material, the more you use it, the brighter it is. It is characterized by good strength, strong corrosion resistance and unchanged color.

There are also many types of stainless steels, which can be mainly divided into ferrite and austenite. Ferritic stainless steel is magnetic, commonly known as stainless iron, long time, bad environment will also rust, only austenitic stainless steel will not rust, the identification method is simple, with a magnet to try to identify. Pure copper lock series:

Pure copper is one of the widely used lock materials, its mechanical properties are good, corrosion resistance and processing performance are good, and the color is gorgeous, especially the copper forged handle and other lock decorations, the surface is flat, the density is good, no pores, sand holes. It is both firm and anti-embroidery, and can be used to plate 24K gold, placer gold, antique, rose gold and other surface treatments, which looks magnificent, noble and generous, and adds a lot of color to home decoration.

The lock cylinder of the door lock is mostly made of copper (good quality), and many are made of zinc alloy (poor quality). We need to choose a lock with a large number of key teeth, because the more teeth of the key, the greater the difference, and the lower the mutual opening rate of the lock. The choice of door lock style type should be determined according to personal appreciation level and hobbies, and the choice of door lock should consider the width and thickness of the door frame, and pay attention to the lock with the same opening direction as the door.

Observe the appearance quality of the product, whether it is smooth and smooth, whether the handle and cladding parts and related accessories are complete, whether the surface color of the electroplating parts and painted parts is bright and uniform, and whether there are defects that affect the appearance such as blistering, layering, rust, oxidation signs and damage.

1. High-grade imported door handles have a full set of imported and imported accessories for domestic assembly of celery, ** different, and attention should be paid to distinguishing when purchasing. In addition, if the merchant says that it is imported, he should be able to issue a customs entry form.

2. No, the more complex the structure, the more expensive the lock. The locks of a double tongue are not necessarily more expensive than those of a single tongue. In general, the insurance factor of a modern door lock has little to do with the complexity of the opening and closing procedure.

A lock that is simple to operate is not necessarily unsafe, and a lock that is very complex to open is not necessarily secure. A properly designed door lock switch operating procedure should be clear at a glance and can be easily operated.

3. Generally at the same price, the flexibility of the lock spring made in Taiwan is better than that of the lock spring produced in China.

4. The locks made in Zhejiang are generally more material-saving than the locks made in Guangdong, which is reflected in the thinner lock head and key and the smaller lock cylinder, so it should be relatively cheap.

5. Look at the lock not only to see the feel, but also to pay attention to whether it has a quality assurance certificate, which should generally be guaranteed for five years.

How to distinguish between the three levels of door locks?

1. A-level lock, if you choose A-level lock, then its anti-theft level is the weakest, some thieves want to open A-level locks, and it will be able to get it in a few minutes. This kind of lock cylinder generally uses a cross key, and the structure is relatively simple. Some professionals may be able to open it in less than a minute, so it has a relatively low security factor.

2. B-level lock, if you want to open B-level lock, there is still a certain degree of difficulty, and some professionals can extend the unlocking time to a few points late. Compared with the A-type lock, some irregular lines have been added, which deepens the difficulty, and its structure has also changed, for example, the double-sided blade lock cylinder is used, so the difficulty is increased when the lock is opened.

3. C-level code lacks locks, if you choose C-level locks at home, it is undoubtedly the safest. If you want to open the lock, some professionals may take several hours to be able to open it, which will increase in difficulty, increase the security factor, and **will follow**.

Decorating the family is a very troublesome thing, not only to choose a variety of details of the decoration materials, but also to choose furniture with the family in the later stage, which is simply to make our body and mind exhausted, there is no way to wait for the completion of the decoration with peace of mind, if you do not stare at the decoration master work, and afraid of slowing down the decoration progress, and the decoration materials are more uneasy for others to buy, in case the purchased materials do not meet their own ideas, which also causes a waste of their own funds, In the end, you can only choose decoration materials by yourself running around, and purchase them according to the requirements of the decoration master and your own requirements, so that you will be the most satisfied.

After the end of the decoration, we immediately replaced the door lock at the entrance and exit of the home, after all, the door lock was handed over to the decoration master when the decoration was carried out, so that he could enter the home at any time for a total group, without delaying the working time, in case of emergency, there are many people who will choose to replace the door lock after the decoration is completed, so how should we choose when choosing the door lock?

When choosing a door lock, of course, the first thing to look at is the material, the door lock is usually made of stainless steel, aluminum alloy and other materials, these materials have their own unique characteristics, such as the door lock made of stainless steel materials, in terms of strength is stronger than other materials, corrosion resistance is also better, but there is a relatively big disadvantage is that the color is relatively single, can not allow consumers to choose their favorite color.

The second is to observe the detailed position of the door lock, from the details of the processing can be seen whether the door lock has quality problems, in some of the better quality door lock categories, we can easily feel the heavy feel of the door lock, and how to rotate after opening the door lock, these feelings are the most direct, and more detailed words can pay attention to the end of the lock handle, the deadbolt and the four corners of the lock body.

The core element of choosing an indoor door lock is the material, inferior door locks are easy to rust, or the lock cylinder often has problems, and the common door lock materials on the market now are: stainless steel door locks, space aluminum alloy door locks, zinc alloy door locks. Then you have to consider whether it matches the decoration style of the home, and whether the appearance of the door lock is in line with your own aesthetics.

Be sure to choose some with a relatively high security factor, try to choose some big brands, such as Wang Li's, and then you can also choose smart locks or password locks.

1. Look at the lock material, generally speaking, its material is stainless steel, copper, aluminum alloy, etc., and different materials of locks have different advantages and disadvantages. For example, stainless steel locks have high strength, strong corrosion resistance, and do not change color, but the forging performance is not good, and the style and color are relatively simple; The copper material has superior mechanical properties, and is generally used to make European-style high-grade door locks, which are relatively high in terms of quality and grade; Zinc alloy has strong wear-resistant, corrosion-resistant and other properties, and is relatively easy to cast, with a wide range of styles and patterns. 2. Look at the surface treatment of the lock, generally speaking, its surface treatment process can be divided into electroplating, spraying and coloring, the surface treatment is equivalent to a layer of protective film, which is not only a decorative role, but also a protective role, it can play a role in anti-corrosion and anti-rust, which can make the lock more beautiful and durable, and have a longer service life.

The locks are mostly electroplated with a delicate and smooth coating, uniform and moderate, bright color, no bubbles, rust and oxidation signs.

1. Choose a brand of smart lock. 2. Choose a model that has been on the market for many years and still sells well. 3. Don't covet too many functions, 4. You must ask for a professional.

person to carry out the installation.

1. It depends on the material of the lock, from good to bad, there are copper, stainless steel, zinc alloy, aluminum, iron, etc., copper locks are the best, it is recommended to buy stainless steel to buy 304 materials, and to buy aluminum, you need to buy space aluminum. Don't buy an iron lock, because the surface plating layer will rust if it falls off, and the lock will be useless in less than a month. Follow the door selection:

When choosing a lock, first of all, you should pay attention to choosing a lock that is consistent with the opening direction of your own door, which can make it more convenient to open and close the door; Secondly, pay attention to the width of the door frame, under normal circumstances, the ball lock and handle lock can not be installed on the door less than 90mm, and the width of the skeleton around the door is above 90mm and below 100mm, and the ordinary ball lock 60mm deadbolt should be selected; For more than 100mm, you can choose a lock with a large cover, that is, a 70mm deadbolt; In addition, the thickness of the door is also an important option.

2. Associated with wear resistance is the material of the door lock. In the selection of materials, you can use "seeing", "checking" and "listening" to master. Looking at its exterior color, locks made of pure copper are generally polished and frosted, and the color is darker than copper plating, but it is natural.

Weighing its weight, pure copper locks feel heavier, while stainless steel locks are significantly lighter. Listening to the sound of its opening, the sound of the copper-plated lock opening is relatively dull, and the sound of the stainless steel lock is very crisp.

1. Pay attention to correct use: Do not twist hard when using it to avoid damage to the door lock. Do not stuff toothpicks, needles, etc. into the lock slot to avoid damage to the door lock, if you find that the lock slot is blocked, you need to remove the blockage immediately, so as not to ring the sound of the shadow mountain to the normal use of the door lock.

2. Pay attention to cleaning: When the outside of the door lock is stained with dirt, you can use a rag to wipe it, but you can not use dish soap, chemical solvents, etc. to wipe it, so as not to damage its surface, resulting in fading, paint and other phenomena. If there are water stains on the door lock and its handle, it is recommended to use a dry rag to absorb the ambush to avoid rust and affect its aesthetics.

3. Pay attention to frequent inspection: In use, it is recommended that you should check regularly, once a month or once every six months. During the inspection, if the door lock is found to be faulty, the lock repairer should be asked to repair or replace it in time.

4. Pay attention to maintenance: In daily use, if you find that the door lock is not smooth when opening or turning, it is recommended to smear some lubricating oil or pencil powder in the lock cylinder groove, so as to make it smoother when opening and closing. It should be noted that no other oil should be added, so as not to stick to the internal spring and cause the door lock to not rotate and open normally.

1. Choose a brand: The door locks on the market seem to be roughly the same, but in fact, there are big differences in the quality of different brands of door locks, so it is recommended to choose high-end brands, and the quality is more guaranteed, such as Yajie, Guli, Baodeli, Sanhuan and so on.

2. Select specifications: When choosing a door lock, you need to choose according to the thickness of the door and the door frame, so that the matching lock can give full play to its safety performance, so when buying a door lock, you need to measure the thickness of the door and the door frame in advance, and then screen.

3. Choose the direction of unlocking: because the door has two ways of single opening and double opening, so before the purchase of the Zen cover, you must confirm the direction of the door switch, if the hinge is on the left side of the door, you need to choose the left door lock, if the hinge is on the right side of the door, you should choose the right door lock.

The anti-theft level of the door lock is divided into three categories, the owner can choose according to the actual needs, if it is an indoor door anti-theft level does not need to be too high, but the entrance door must choose a high anti-theft level to ensure that the security attack early.
