What is the standard of security door lock? How to choose the security door lock?

Now with the development of economy, people's living standards are getting higher and higher, and their own safety requirements are also constantly improving. In the past, ordinary doors and windows were generally installed at home, but now more and more modern people install security doors. In fact, although there is no big difference in the appearance of the security door, there is Gan Kun in its anti-theft lock. Different grades of lock cores have different anti-theft effects when used, and the higher the grade, the better the anti-theft effect. The following small series will comprehensively introduce the security door lock standard, and I believe you will have an answer after reading it.

According to GA/T73-94 "Mechanical Anti-theft Lock" issued by Public Security 1994. Theft-proof door locks are divided into three grades, A-class locks, B-class locks and super-B-class locks. The specific criteria are as follows:

Level a

Technology startup: not less than 1 min.

Destructive opening: not less than 15 minutes.

Market price: 50~ 100 yuan.

At present, the A-class anti-theft locks on the market mainly include a one-word key and a cross key. The internal structure of Class A lock core is very simple, limited to the change of marble, and the marble grooves are few and shallow. The anti-technology opening time is 1 min, and the mutual opening rate is extremely high. The marble structure is single-row marble or cross lock.

b grade

Technology startup: no less than 5 minutes.

Destructive opening: not less than 30 minutes.

Market price: 200~500 yuan.

The key of Class B lock is a flat key with double rows of marble grooves. Unlike Class A lock, there is a row of irregular lines on the key face. There are three kinds of lock cores: computer double-row lock core, double-row crescent lock core and double-sided blade lock core. The anti-technology opening time is less than 5 minutes, and the mutual opening rate is high. The lock core can be opened in 0/minute with the powerful twisting tool/kloc.

Super class b

Technology startup: no less than 270 minutes.

Market price: 1000 yuan.

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 public security inspection, the technology could not be opened, and the cross-regional opening rate was zero (11 in 6 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, which will make it impossible to open it. At present, there has not been a case of super b theft in the public security door.

Whether an anti-theft door lock brand has strong comprehensive strength is directly related to the quality of anti-theft door lock products. The so-called comprehensive strength includes technology research and development level, manufacturing capacity, product quality, product sales, product after-sales service and so on. When ordinary families buy anti-theft locks, they should know the industry history and scale of this anti-theft lock manufacturer. Generally speaking, brands with many years of industry history have relatively stable product quality.
