What you need to pay attention to when using door locks daily

Usually there are a lot of friends in the use of the door lock will be astringent, or tight, so they like to put the door lock in the ground lubricating oil, so the surface does not look wrong, but the lubricating oil is very easy to accumulate dust after too long to form putty, then not to mention lubrication, the door lock is more likely to fail tighter. Then the best thing to do is to use some pencil scraps or candle scraps, blow into the inside of the lock cylinder and turn it repeatedly.

I believe that friends will encounter the same thing, that is, when the key is inserted into the door lock, it cannot be rotated and forcibly rotated, resulting in the key being bent or even broken. Then these situations are often caused by the gravity of the door leaf itself to sink, lock the door or open the door will not be smooth, then or forcibly rotate, the key will be broken will increase more trouble. So the correct solution is to find out the cause first, if it is really the reason for the sinking of the door leaf, then fix the screws tightly.

When opening and closing the door, the most taboo is to force the door, so that it has a strong collision with the door frame, which is very damaging to the door or the door lock. To protect the lock, the handle should be rotated and the door closed gently.

Therefore, the maintenance of the door lock is very simple, but once the door lock has a problem, it will be very troublesome, so start with small details.

Precautions for the daily use of locks.

Some friends, when opening the door, always push the door very hard to push the door frame, so it is not good to have multiple door locks. After opening the door, we should rotate the handle, let the deadbolt lock, and then release the hand after combining the door frame, in short, to avoid serious collision of the door lock, otherwise it will shorten its life.

When opening and closing the door, the lock body must be turned, and it will become inflexible after a long time. Therefore, we must ensure that there is lubricant in the rotating part of the lock body to reduce the wear and tear of the lock body and prolong the service life. In order to ensure the safety of the lock, it is best to check whether the lock pegs are loose frequently.

In addition to the lock body we will often rotate, the lock cylinder is also a place that we often come into contact with, for a long time, the key will not be smooth in the process of unplugging, therefore, we need to add some items that can lubricate it for the lock cylinder, of course, the lock cylinder is absolutely not able to add lubricants or some oil substances, therefore, we had better choose to add some graphite powder that is the powder of the pencil lead, which can play the best lubricating role in the lock cylinder.

Some friends often like to drip some lubricating oil on the keyhole when the door lock is astringent or tight, so that the door lock may be smooth soon, but because the oil is easy to stick to the ash, it will be easy to slowly accumulate dust in the keyhole in the future, and form putty, which makes the door lock more likely to fail, therefore, unless necessary, do not add lubricant to the net keyhole. You can sharpen some pencil scraps or some candle scraps, blow them into the inside of the lock cylinder through a thin tube, and then insert the key and turn it several times.

Sometimes, due to the gravity of the door leaf itself or the door loose page, the door leaf sinks, and the door is locked or the door is not opened smoothly. At this time, it is often very difficult to open and lock the door with a key. At this time, do not forcibly twist the key, so as not to break the key and increase the trouble.

You should look at the reason first. If the door leaf sinks due to loose loosening, the loose loose leaf should be fixed tightly with screws. If the door frame is deformed or its reasons are irreversible, you can start from the door frame and expand the deadbolt accordingly, so that the door lock can be restored to normal and smooth.

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. 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**.

According to the use, it is divided into: anti-theft locks, heaven and earth locks, split locks, door locks, door locks, bathroom locks, passage locks, sliding door locks, locker room door locks, door locks, etc.

Inside the house, press the movable handle to push it outward (open the door outward) or pull it in (open the door inside). After the door is opened, the angle should not force it to exceed the normal opening angle (the normal opening angle is 90 degrees-100 degrees). When the user enters the house after the door is opened, please check whether all the deadbolts have been retracted before closing the door, if not, please press the movable handle in the house, and then close the door after the deadbolt is completely retracted, and the same method is used to close the door after the user goes out.
