What lock is the safest for an anti theft door? What door locks are the safest for home use

Class B lock: The most secure anti-theft lock in 2013.

The safest is the most difficult lock to open in the case of anti-locking.

For ordinary anti-theft door locks, the lock and the lock cylinder are separated, and the security is not safe, and the key is that the lock cylinder is not easy to open.

The safest is the most difficult lock to open in the case of anti-locking, and so far there are the following two:

1. The serpentine lock, there is no longer a string of small holes on its key, but a serpentine path, a bit like a car key.

2. The biggest feature of the blade lock is that its lock cylinder is built into the lock, for this kind of lock, it is almost impossible to destroy the lock cylinder to open the door.

Some things to pay attention to in the maintenance of door locks:

1. Lubricant.

Some friends often like to drip some lubricating oil on the keyhole when the door lock is astringent or tight, so that the whole body of the door lock may be smooth immediately, 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 malfunction.

The correct solution: 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.

2. The door is not opened smoothly.

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.

Correct solution: You should look at the cause 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.

The fingerprint lock is the safest, it is the perfect crystallization of computer information technology, electronic technology, mechanical technology and modern hardware technology. The characteristics of fingerprints have become the most important evidence for identity identification, and are widely used in the fields of public security, criminal investigation and justice.

Fingerprint sensors are mainly optical sensors and semiconductor sensors, optical sensors mainly refer to the use of COMS and other light sensor devices to obtain fingerprint images, and the market is generally made into the form of an integral module, such sensors are low.

With the popularization of science and technology and the development of smart homes, more and more people have begun to choose fingerprint locks.

In addition to the function of opening the door, the fingerprint lock generally has the function of adding, deleting and emptying the fingerprint, and the high-performance fingerprint lock is also equipped with a human-computer dialogue system such as LCD touch screen, with a high level of intelligence;

The fingerprint management function is: add fingerprint, delete fingerprint, clear fingerprint, set system parameters and many other functions, while ordinary users only have the function of opening the door.

The choice of household door locks or Anerfa brand is good, the door locks they produce, safe and secure, simple to use, the most reasonable, hehe, it is really a combination of many advantages, trustworthy.

This time, we bought 9 popular smart door locks at a time, covering the popular models of popular brands such as Xiaomi, Luke, Samsung, Dessmann, etc., with a series of tests to help you find the most suitable product, and take you to fully understand the sub-category of smart door locks. (There are benefits at the end of the film).

The lock cylinder of the anti-theft door lock is generally divided into Class A, Class B and Super Class B. Now in many door industry markets, in addition to some old-fashioned anti-theft doors using A-level lock cylinders, most of the family's anti-theft doors are B-level locks, and some newly installed anti-theft doors begin to use super B-level locks. Therefore, it should now be in a period of replacement from B-level to super B-level lock cylinders.

With the continuous development of science and technology, the security of traditional mechanical door locks has gradually declined, and the simple physical protection of mechanical locks has been unable to meet the current home security, and the rapid rise of smart locks has also confirmed this.

So, what type of home smart lock is more safe and reliable?

1. Look at the material, titanium alloy is better.

2. Look at the lock cylinder, it is better to be super B-level.

3. Look at the manufacturer, and take the historical scale as the judgment standard.

It is not good to buy it in one place, you can search in Tmall and so on, if you want high security, you can buy fingerprint locks, and now you have basically started to use fingerprint locks, like my own home is also a fingerprint lock that has just been installed, although it costs a little money, but it is worth it, one-year warranty, lifelong maintenance, very worry-free, I use Helster, you can refer to it!

First of all, you should have a general understanding of the anti-theft door lock: the anti-theft door lock will generally have several structures such as "blades, IC cards, bullets and fingerprint locks". Among them, "bullet lock" and "blade lock" are more common in people's lives, while the anti-theft door locks of "IC card lock" and "fingerprint lock" are mostly used in the anti-theft system of enterprises, institutions and state administrative organs.

Although the lock cylinder of the anti-theft door lock is only a small piece, it is an important part related to the security of the entire anti-theft door.

At present, the anti-theft door lock cylinder on the market is divided into three categories: from low to high for A-level locks, B-level locks, and super B-level locks, among which the super B-level lock has the best anti-theft function. When a layman goes to buy a lock, you can tell which level your lock is by looking at the pin groove and milling groove on the key.

According to people in the know, there will be two kinds of lines on the key, one is point-shaped, which is the marble slot; One is to bend irregular lines, which is milling grooves.

The super B lock is the most complex, in addition to having a pin groove and a milling groove on both sides, there is also an extra row of pin grooves on the side of the key, and the key shape is a single-sided blade inner milling groove or external milling groove key. Class A locks are recommended to be replaced, and the lock cylinder is best to be upgraded once every five years. If you decide to change a lock, it is recommended to change the lock cylinder of a better brand, which will be safer.

Now it's not very safe to use any lock, someone can crack it, you can choose face unlocking, fingerprint unlocking, password unlocking, three-in-one lock, greatly increasing the anti-theft ability.

Nowadays, high-tech is becoming more and more developed, and we are more pursuing the perfect intelligent system of daily life. The quality of Samsung smart door locks is higher, and Dessmann's cost-effective is better, for which smart door locks are stronger, the key is to choose according to the customer's preferences and requirements.

We can choose from a number of levels:

1) Price: Nowadays, the price of smart door locks is widely in the thousands, there is no need to pursue the perfect very expensive fingerprint password lock, but there is no need to buy too cheap casually, generally speaking, two or three thousand smart door locks will have a very good quality.

2) Security factor: The anti-theft lock cylinder of the smart door lock is roughly divided into three levels: A, B and C, and the security factor of the C-level anti-theft lock cylinder is higher.

Think of how impossible it seems to people to stay up late at night. Not only do we now have to lock the door, but we also use a more advanced combination lock security door. But some people say that this kind of high-tech home security door still can't hide from the care of thieves.

In the current market, there are two main types of password lock anti-theft doors, one is the anti-theft door made of mechanical combination locks, and the other is the electronic password lock anti-theft door.

Compared with the traditional ordinary security door, the combination lock security door is more secure.
