with the development of society, people's anti-theft awareness is constantly improving. Anti theft doors are widely used in today's family life. I believe everyone knows about the level of anti-theft locks. Now the style, type and level of anti-theft locks in the market are not used. According to the principle of anti-theft lock cylinder, they are divided into leaf lock, magnetic lock, marble lock, fingerprint lock, IC card lock, etc. Next, I will introduce the identification method of anti-theft lock level

classification of anti-theft locks

according to grades, anti-theft locks can be divided into three types: A-level lock, B-level lock and super-b-level lock. The security performance of different levels of anti-theft door locks will be different, the strength of anti-theft will increase with the level, and the internal structure is also different. Now let's introduce these three locks in detail

class a lock

at present, class a anti-theft lock keys on the market mainly include flat key and cross key. The internal structure of A-level lock cylinder is very simple, which is limited to the change of marbles, and the marbles slots are few and shallow. The anti technical opening time is within 1 minute, and the mutual opening rate is very high. The structure of marbles is single row marbles or cross lock

b-level lock

b-level lock key is a flat key with double rows of marble slots. The difference from A-level lock is that there is a row of curved and irregular lines on the key surface. There are three main types of lock cylinders, including computer double row lock cylinder, double row crescent lock cylinder and double-sided blade lock cylinder. The anti technical opening time is within 5 minutes, and the mutual opening rate is high. With the strong twisting tool, the lock cylinder can be opened within 1 minute

super-B lock

the shape of the key is a single-sided blade inner milling slot or outer milling slot key, and the type of lock cylinder is side column lock cylinder; The Ministry of public security detected that the technology could not be opened in 270 minutes, and the mutual opening rate of the areas was zero (1/16 million). The billiard structure is double row blades and V-shaped side columns for locking; If the lock cylinder is opened with a strong twisting tool, the interior of the lock cylinder will be damaged, self explosion and locking, resulting in failure to open

identification of anti-theft lock level

identification method 1

first of all, for the anti-theft door lock of level a, its internal structure adopts a row of marble structure locks, such as A-shaped lock, crescent lock and most of the lock cylinders adopt level a locks. The anti-theft performance is very poor, and it only takes two seconds to be opened

next is the level B anti-theft door lock. The anti-theft performance of level B anti-theft door lock is a little better than that of level a anti-theft door lock, but it can't achieve the real anti-theft performance at all. The internal structure of level B anti-theft door adopts a part of single row marbles and double row marbles, as well as the combination of blades. This is the level B anti-theft door lock. If it is the work of a professional unlocking craftsman, it only takes one to five minutes to open it

finally, there is the super-B level anti-theft lock. The internal structure of the super-B level anti-theft lock adopts the lock composed of multi shot marble and multi shot blade, which is the highest level of the current anti-theft door lock. Moreover, this level of anti-theft door lock has higher security performance and stability. Some basic theft technologies cannot be opened unless it is destructively opened, In order to really open the anti-theft door lock beyond class B

identification method 2

the level identification method of anti-theft door lock, the simplest tool is to use the key to identify, so how to identify? But from the key, we can distinguish the level of anti-theft door lock. Don't believe it. Look at your key carefully. If there is a row of single-sided single slot on it, it means that it is A-level door lock and needs to be replaced; If it is double-sided single slot and double row, it means that it is a B-level door lock; If your key is double row and single slot, or double-sided, and there is a curve or a blade next to it, it means that it is a super-B door lock with reliable anti-theft performance. In addition to strengthening the safety performance of the door lock, there are other external precautions that also need your attention, such as cat's eye. You should strengthen the protection and remember to lock at any time

editor's summary: This is the end of the anti-theft lock level identification method. I hope it will be helpful to you. The invention of anti-theft lock is for security. With the development of science and technology, the anti-theft lock is constantly upgraded, and the anti-theft ability is also continuously enhanced. If you still have the most basic A-level lock in your home, it is recommended that you replace it as soon as possible for the safety of your home.
