Abstract

The invention relates to a civil air defense door structure and use method, which includes a door body, a door frame and a locking device, the locking device includes two sets of locking mechanisms respectively installed on both sides of the door body, each set of locking mechanisms includes Or two inserting rods that slide away from each other, a rotating shaft that is rotatably connected to one side of the door body and between the two inserting rods, and a connecting block sleeved and fixed on the outer wall of the rotating shaft; the two sides of the connecting block are hinged respectively. Connecting rods, the ends of the two connecting rods away from the connecting blocks are respectively hinged to the opposite ends of the two inserting rods; one side of the door body is equipped with a driving mechanism for driving the two connecting blocks to rotate; the two connecting blocks of the door frame Two slots are respectively opened on the side, and the inserting rods are inserted into the slots one by one. The invention is convenient for locking and unlocking the air defense door.

Description

technical field [0001] The invention relates to the technical field of civil defense doors, in particular to a structure and a use method of a civil defense door. Background technique [0002] The civil air defense door is the door of the entrance and exit of the people's protection project. It is the activity that the government mobilizes and organizes the masses, adopts air raid defense, disaster relief measures, implements rescue operations, and prevents and mitigates disaster hazards. The civil air defense door belongs to the civil defense protective equipment. The civil air defense door is generally made of hard steel material, which has a certain anti-shock wave effect and effectively guarantees the safety and stability of the civil air defense space. [0003] Existing civil air defense doors include locking devices, which are the most important structure for civil air defense doors to resist explosion shock wave residual pressure, and are the most important parts to ...
