An explosion-proof door assembly

Abstract

The invention relates to the technical field of anti-theft doors, in particular to an explosion-proof door assembly. An explosion-proof door assembly, which includes a door frame and a door. The door includes a door body and a door lock mechanism. The door body is installed in the door frame. Mechanism, linkage mechanism and locking mechanism, the locking mechanism is connected to and controls the locking mechanism through the linkage mechanism, the locking mechanism includes at least a locking piece connected to the linkage mechanism, and the locking piece includes a connecting section connected to the linkage mechanism, a guide link It not only has a good anti-theft function, but also has a high-quality explosion-proof effect. With the cooperation of various mechanisms, it can realize remote electric control and manual anti-lock function. , and has the ability to resist strong external forces.

Description

technical field [0001] The invention relates to the technical field of anti-theft doors, in particular to an explosion-proof door assembly. Background technique [0002] A door lock is, as the name implies, a device used to lock a door to prevent others from opening the door. There are many types of door locks, and the requirements for door locks are different in various occasions. Ordinary families generally use anti-theft door locks, which have high security and are relatively cheap. It refers to the combination of two or more lock cylinders with different principles on the same lock. The most common composite lock on the market is the combination of a tumbler lock and a magnetic lock. Professionals call it a magnetic composite lock. The lock must first destroy the magnetism of the lock before it can be technically unlocked. However, the magnetic composite lock also has a fatal weakness. If the key is not kept properly, it will be demagnetized if it is hit by gravity or e...

There are many types of door locks, and the requirements for door locks are different in various occasions. Ordinary families generally use anti-theft door locks, which have high security and are relatively cheap. It refers to the combination of two or more lock cylinders with different principles on the same lock. The most common composite lock on the market is the combination of a tumbler lock and a magnetic lock. Professionals call it a magnetic composite lock. The lock must first destroy the magnetism of the lock before it can be technically unlocked. However, the magnetic composite lock also has a fatal weakness. If the key is not kept properly, it will be demagnetized if it is hit by gravity or encounters high temperature. Once demagnetized, the lock cannot be opened. The explosion-proof performance of this type of anti-theft lock is not very good. If a relatively strong external force is applied to it, it will break as desired, especially the lock cylinder is easier to break
