Abstract

The invention discloses a safe and efficient civil defense door alloy structure. A door frame fixedly arranged on a wall is included. An opening in one side of the door frame is closed through a wall,and an opening in the other side is selectively opened and closed through a civil defense door alloy plate. Sliding rails are arranged in an upper frame and a lower frame of the door frame. The civildefense door alloy plate can be arranged in the sliding rails in a relative sliding manner for selective opening and closing. The civil defense door alloy plate comprises a civil defense door alloy plate body. The upper end and the lower end of the civil defense door alloy plate body are arranged in the corresponding sliding rails through wheels in a sliding manner, and meanwhile a sliding driveassembly is arranged at the bottom of the civil defense door alloy plate body. Under the drive action of a drive motor, the civil defense door alloy plate body slides in the sliding rails for selective opening and closing. By means of the safe and efficient civil defense door alloy structure, automatic civil defense door opening and closing are achieved, potential safety hazards existing in manualoperation are avoided, and meanwhile the seal effect during closing is ensured.

Description

technical field [0001] The invention relates to the field of civil air defense door manufacturing, in particular to an alloy structure of a safe and efficient civil air defense door. Background technique [0002] The civil air defense door is the door of the entrance and exit of the civil protection project. The classification of civil air defense doors is relatively clear. There are ordinary single and double protective airtight doors and airtight doors. This type of door is the earliest to be finalized and has been widely used. It is characterized by simple structure, reliable operation and convenient maintenance, and is suitable for the entrance and exit of various civil air defense projects. The civil air defense door is very heavy, and it is usually used in the way of split rotation or single swing rotation, which requires manual opening, and it is easy to hit people when opening and closing the door, which not only poses safety hazards, but also has poor sealing effect...
