Qualified entry doors generally use anti-theft special locks that have been tested by the public security department. At the same time, steel plates with a thickness of more than 3.0mm should be used for protection at the locks. At present, many anti-theft special locks are multi-directional locks. Its advantage is that not only the door lock is locked, but the upper and lower crossbars can be inserted and locked to fix the door. Greatly increases the anti-pry performance of the door. The "GA/T73-94 Mechanical Anti-theft Lock" issued by the Ministry of Public Security of the People's Republic of China clearly stipulates that mechanical thieves anti-theft door locks are divided into ordinary protection levels and advanced levels, which are represented by A and B levels.
Class A lock refers to a lock with an anti-destructive opening time of not less than 15 minutes and an anti-technical opening time of not less than 1 minute. Class B lock refers to a lock with an anti-destructive opening time of not less than 30 minutes and an anti-technical opening time of not less than 5 minutes (anti-technical opening refers to the ability of professional and technical personnel to use special tools to open locks). And under the same circumstances, the security performance of Class B anti-theft lock is 5 times that of Class A lock.
