Anti-theft locks are classified into three types: A-class locks, B-class locks and super-B-class locks. Different levels of anti-theft door locks will have different safety performance, and the intensity of anti-theft will increase with the level, and the internal structure is also different. Let’s introduce these three kinds of locks in detail now!
Class a lock
At present, there are mainly one-word keys and cross keys for Class A anti-theft locks on the market. The internal structure of Class A lock core is very simple, which is limited to the change of marble, and the marble grooves are few and shallow. The anti-technical opening time is within 1 minute, and the mutual opening rate is extremely high. The marble structure is single-row marble or cross lock.
Class b lock
The key of Class B lock is a flat key with double rows of marble grooves, which is different from Class A lock in that there is a row of crooked and irregular lines on the key face. There are three main types of lock cores: computer double-row lock core, double-row crescent lock core and double-sided blade lock core. The anti-technical opening time is within 5 minutes, and the mutual opening rate is high. The lock cylinder can be opened within 1 minute by strong twisting tool.
Super class b lock
The shape of the key is a single-sided blade internal milling groove or external milling groove key, and the lock core type is a side column lock core; After 270 minutes of testing by the Ministry of Public Security, it was impossible to open the technology, and the inter-regional opening rate was zero (one in 16 million). The marble structure is locked by double rows of blades and V-shaped side columns; If the lock core is opened with a strong twist tool, the inside of the lock core will be destroyed and locked by self-explosion, resulting in failure to open it.
