Explosion door assembly

Abstract

The invention relates to the technical field of security doors, in particular to an explosion door assembly. The explosion door assembly comprises a door frame and a door. The door comprises a door body and a door lock mechanism. The door body is installed in the door frame. A lock groove is formed in the door frame. The door lock mechanism is installed on the door body. The door lock mechanism further comprises a locking mechanism, a linking mechanism and a closing mechanism. The locking mechanism is connected with and controls the closing mechanism through the linking mechanism. The lockingmechanism comprises a locking piece at least connected with the linking mechanism. The locking piece comprises a connecting section connected with the linking mechanism, a guide connecting rod sectionand a closing section going deep into the lock groove. The explosion door assembly has a good antitheft function and also has an excellent anti-explosion effect, and through the cooperation of the various mechanisms of the explosion door assembly, the explosion door assembly can have a remote electric control function and can also have a manual double locking function and meanwhile has the capacity of resisting the strong external force action.

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
