[0002] Explosion-proof doors are safety protection facilities that have the ability to resist explosion shock waves and prevent the continuation of explosion hazards. They are usually designed and installed in places with explosion hazards, such as chemical plants, oil depots, arsenals, etc. Explosion-proof doors can withstand the impact pressure generated by the explosion when an explosion occurs, prevent the explosion shock wave and flames from causing serious damage to the surrounding area, and protect the safety of personnel and equipment.

[0003] According to a Chinese patent with the publication number of "CN216866473U", an explosion-proof door is disclosed, including a door body, a telescopic lock mechanism, a hinge and a door frame for embedding and fixing in a wall, the telescopic lock mechanism includes a turntable, a rotating handle and a door lock assembly, the turntable is arranged on a first surface of the door body, the rotating handle is arranged on a second surface of the door body, and the door frame is provided with a plurality of buffers for cooperating and abutting with the door body. The beneficial effects of the present application are as follows: the door body formed by laser welding is connected to the door frame through a hinge, and an external key matching the door lock assembly is inserted to lock or unlock the door body, and the turntable or the handle is rotated to make the door lock assembly fix the door body to the inner side of the door frame, thereby reducing the harm caused by the explosion to the building and the human body. When the above-mentioned explosion-proof door is in use, no automatic opening and closing mechanism is arranged, which makes it easy for the impact force of the explosion to cause the explosion-proof door to deform when an explosion occurs, thereby making it easy for the explosion-proof door body to be unable to be opened. Therefore, an explosion-proof door with an automatic buffer safety opening and closing device is proposed to solve the above-mentioned problems. Utility Model Content
