What kind of door lock is good?

What are the top ten brands of door locks and which ones are of good quality?

As a security product, door locks must be safe and stable. Security can be measured from two aspects: first, it can resist deliberate violence such as vandalism, pranks and prying. In this respect, the mechanical strength of mechanical locks and electronic door locks can generally meet the requirements. Among all kinds of door locks, only radio frequency card electronic door locks are fully enclosed and have the best safety. The second is to prevent technical opening, and the mechanical lock has poor ability to prevent technical opening. No matter what structure the mechanical lock is, it can be opened in other ways. The key can be copied, which is a great security risk. In the electronic door lock, the key card of the magnetic card is easy to be copied because there is no password restriction. IC card and RF card completely solve the problem of preventing technology from starting. So how to choose a good door lock is the biggest worry for users, but I know that there is a website, good-best, which ranks door locks, such as Wang Li, Golden Point Atomic, Wanjia, Baode An, Coulee, Simto, Modile and Meribao, all of which are very good brands, and the landlord can refer to them.

What kinds of door locks are there?

A door lock is a device used to lock the door to prevent others from opening it. This device can be mechanical or electric, and electric needs electricity.

Classification: hotel locks, apartment locks, smart locks, fingerprint locks, glass locks, etc. Used in various electronic locks. There are many classifications of door locks, and the requirements for door locks are different in various occasions. Ordinary families generally use anti-theft door locks, which are highly secure and relatively cheap. In some high-end places and secret institutions, password locks and fingerprint locks will be used, which are very safe and expensive; Glass doors are used in many public places, so glass door locks will be widely used.

How to choose anti-theft door locks, what kind of door locks and brands are good?

How to choose anti-theft door locks, what kind of door locks and brands are good? Teach the skills of several methods: remember

Collection. Methods/steps

1, look at the lock material

Lock materials on the market are basically divided into stainless steel, copper, zinc alloy, steel and aluminum. Stainless steel has good strength, strong corrosion resistance and unchanged color, and is the best lock-making material. Copper is universal, superior in mechanical properties and expensive; High-quality zinc alloy is strong, wear-resistant, corrosion-resistant and easy to form, and is generally used to manufacture mid-range locks. When buying, look carefully at the lock material.

2. See lock surface treatment.

There are generally three kinds of surface treatments for locks: electroplating, spraying and coloring. Through these surface treatments, a protective film can be formed for the product, which plays an anti-corrosion and anti-rust role, and at the same time makes the product more beautiful and durable, which can directly measure the quality of the product. See if the surface of the lock is flat and smooth. Generally, locks with good quality are electroplated. The coating is moderate and uniform, with bright colors and no signs of bubbles, rust and oxidation. 3. Look at the functional design and key parts of the lock.

There are many kinds of locks, and the choice of locks depends on where they are used. Big brands with high quality requirements have very detailed product classification according to different functional requirements, such as access locks, bathroom locks, storage locks, large door locks and so on. 4. See the lock implementation standard.

Foreign countries have very strict standards for hardware locks, so the quality of imported products is relatively superior. At present, the Ministry of Light Industry has used some foreign standards for reference, and revised the original GB to QB with higher requirements. Small manufacturers don't implement standards in order to save costs, while big brands will implement standards when producing products. 5. Look at the lock manual and quality inspection report.

It depends on whether there are instructions and installation instructions, and the effort lies in the details. See if the product has passed the inspection of relevant national quality inspection departments. Usually, the technical indicators of inferior door locks can not meet the national standards. Then, carefully check whether the accessories in the door lock package are complete.

What kind of lock core is good for household security doors?

According to the structure, the lock core of anti-theft door is divided into grade A, grade B and grade B:

Class A: The key is flat, with only one side and single row of bullet slots. The cross key is basically Class A, which can be opened in about two or three minutes.

Class B: From the key point of view, it is a double-sided double-row bullet slot. Even with tools, skilled workers need some time;

Super B: It is the safest level at present. From the key, there is a double-sided double-row bullet slot with a blade or curve next to it. The technical standard of lock core design is more than 270 minutes.

Generally, the super B lock core is replaced, that is, the key has a serpentine groove, which requires a 200 yuan.

I bought it online, which is 70-80 yuan. Master lock repairer earns once 100.

If you can, you'd better change it yourself, which is both economical and safe. Meribao lock core is very good, 70 yuan.

First, the sequence of removing the lock cylinder:

1. Remove the inner and outer handle panels: the screws are on the handle panels of the house, one above and one below.

2. Remove the inner and outer lock cylinder covers: the screws are on the lock cylinder covers in the house, that is, the left and right sides of the key.

3. Remove the lock cylinder positioning screw: the screw is on the side of the door, in the middle of the lock tongue, and is the same height as the lock cylinder. The thickest is.

4. At this time, the old lock cylinder can be removed: the old lock cylinder can be replaced just like the new lock cylinder.

Secondly, install a new lock cylinder:

The sequence is opposite to disassembly, and several points should be noted:

1. Before installing a new lock cylinder, add a small amount of lock cylinder lubricant. Turn the key several times.

2. Lock core positioning screw must be tightened to prevent the screw from loosening, and then open the door.

3. Don't screw the lock cylinder cover too tightly, so as not to be too exciting and difficult to unlock.

4. When installing the inner handle panel, there is a safety pin below, which should be inserted into the corresponding safety pin hole.

What kind of lock is safer?

Class b lock core is more anti-theft

There are three kinds of lock cores used in the market: A-class, B-class and Super-B-class. The anti-destructive opening time of Class A lock cylinder is greater than 15 minutes, and the anti-technical opening time is greater than 1 minute. Class B locks should be opened for more than 30 minutes under destructive action and for more than 5 minutes under technical action. The biggest feature of super B-class anti-theft door lock is that the anti-technical opening time exceeds 240 minutes.

Lock cores can be distinguished by the number of rows of marbles. Generally speaking, multi-row tumbler locks are superior to single-row tumbler locks, and multi-row invisible tumbler locks are superior to ordinary multi-row tumbler locks. The cost of Class B locks is much higher than that of Class A locks, and most manufacturers in the market produce Class A locks.

Check a and b grades by searching keys. If it is a single row of marbles, the security door is likely to be equipped with a class A lock core. If you feel unsafe, you can consider replacing the super B lock cylinder to improve the overall anti-theft performance of the security door.

The quality of hardware fittings is also a factor that affects the service life of locks. Locks are generally made of aluminum alloy, stainless steel and copper, with aluminum alloy slightly worse and copper the best. The same material, the difference is also great, the qualified locks are fine in workmanship, the unqualified products are rough, the qualified locks open with clear sound, the unqualified locks often have scratches on the surface, the keys are loosely inserted, and the sound is dull.

Fingerprint lock and smart lock are in line with the development trend of smart home, and everyone will use them in the future.

Well-known brands in the market are: Wang Li security door, Frandi security door, Xingyueshen security door, Zhen 'an security door, security door, Longjia security door, Buyang security door and so on.

What kind of anti-theft door lock is the best and safest for community residents?

This question about you is also a problem that puzzles me. My experience is to choose a lock or go to a more formal hardware store to buy it. When you buy them, you should state your own needs. At the same time, many locks have security protocols. Pay attention to workmanship when buying. Good workmanship generally costs high, and of course the anti-theft coefficient is high. What can I say? I'm not afraid of thieves stealing, but I'm afraid of thieves thinking. Even if you change the lock with high safety factor, it is not absolutely safe. You should pay attention to the awareness of prevention at ordinary times.

Specifically, the choice of lock should be decided according to your own needs. From the definition of security, the anti-theft locks on the market are roughly divided into three categories according to the security level from weak to strong, namely: A-class locks, B-class locks and super-B-class locks, and the prices range from tens to hundreds of yuan.

The following is a comparison of the security of all levels of locks.

1, level: a lock safety factor: dangerous users: buyers are mostly renters.

The so-called A-class lock, which is also a common one-word lock, is a kind of lock which is widely used and has the simplest structure in the market at present. There is also a "cross lock", which is relatively rare. It is generally used on old doors and is rotary.

This kind of lock: A thief can open a general A-class lock in 10 second by "tinfoil unlocking method". Generally, people who come to buy class A locks are renting houses. To buy anti-theft locks, most of them are class B locks or super class B locks installed in their own homes.

2. The moderate price of class B lock is determined by the bending degree.

Class B lock has higher security performance than Class A lock. There is a row of winding lines on the key face of class B lock, which we call crescent. The key of Class B lock has double rows of marble grooves. Unlike Class A lock, there is a row of irregular curved lines on the key surface. There are mainly three types of B-type lock cores: computer double-row lock cores, double-row crescent lock cores and double-sided blade locks. "The price of class B locks in our store ranges from 50 to 100 yuan. The price difference lies in the degree of bending and ease of opening. "

3. Super Class B lock will explode and lock itself if it is forcibly unlocked safely.

"At present, the super B lock has the highest anti-theft coefficient. The super B-class key is in the shape of a single-sided blade internal milling slot or external milling slot key, and the lock core type is a side column lock core. According to the public security inspection, this kind of lock core can't be opened in 270 minutes technically, and the regional mutual opening rate is close to zero (11 in 6 million). Super B-class lock marble structure, double-row blades and V-shaped side columns. If a thief uses a powerful twisting tool to open the lock core, the inside of the lock core will be destroyed and locked by self-explosion, which will make it impossible to open it.
