Description

Technical Field

[0001] The utility model relates to the technical field of armored door related equipment, in particular to a safety anti-pry device for armored doors. Background Art

[0002] An armored door is a specially designed door that is usually used to provide additional security and protection. This type of door is generally made of strong and durable materials and is designed to defend against external threats such as intrusion, robbery, terrorist attacks or natural disasters. During the use of the armored door, when it is intruded by prying, the corresponding armored door will generally only need to pry the lock in the normal handle position to loosen, which may endanger personal safety or damage property. Therefore, we need to add anti-pry function to the armored door to prevent potential harm caused by prying the door.

[0003] Traditional armored doors usually rely on a deadbolt to lock the door for anti-theft preparation, which means that the door has relatively few fixed points. An attacker only needs to pry one of the deadbolts to successfully open the door. In addition, the design of traditional armored doors is relatively simple, and it is easy for attackers to find the fixed points, which makes the door vulnerable to positioning attacks. Attackers can find the best position for attack through reconnaissance or research on the structure of the door, increasing the chance of a successful attack. Because the fixed points are single, it is very easy for attackers to find the target and pry the lock, so the security of the corresponding armored door cannot be guaranteed. Utility Model Content
