Sliding type civil air defense door convenient to open and close
The invention relates to the technical field of civil air defense related equipment, and discloses a sliding type civil air defense door convenient to open and close, the sliding type civil air defense door comprises a door frame, a fixed door plate, a movable door plate and a lead screw, and the movable door plate is in sliding connection with the lead screw; an opening and closing mechanism used for controlling opening and closing of the movable door plate is further installed in the door frame and comprises a fixed shaft installed on the door frame in a sliding mode, two sets of tightening assemblies symmetrically installed on the fixed shaft at intervals and a driving assembly installed on the door frame and located below the tightening assemblies. The two driving assemblies are arranged, and the driving assemblies correspond to the tightening assemblies in a one-to-one mode. A pull rope is wound between the driving assembly and the tightening assembly, the pull rope is in a tightened state all the time, the driving assembly is rotated, the tightening assembly can rotate along with the driving assembly, and the lead screw is driven to rotate. The civil air defense door has the effect that the civil air defense door can still be normally opened and closed when the motor is damaged or an external power supply is interrupted.
本申请涉及人防相关设备的技术领域，公开了一种便于开关的滑移型人防门，其包括门框、固定门板、活动门板，以及丝杆，所述活动门板与所述丝杆滑动连接；在所述门框内还安装有用于控制所述活动门板启闭的启闭机构，所述启闭机构包括滑动安装在所述门框上的固定轴、两组对称间隔安装在所述固定轴上的收紧组件，以及安装在所述门框上，且位于所述收紧组件下方的驱动组件，所述驱动组件设置有两组，所述驱动组件与收紧组件一一对应；在所述驱动组件与所述收紧组件之间缠绕拉绳，所述拉绳始终处于绷紧状态，转动驱动组件，收紧组件可随之进行转动，并带动所述丝杆进行转动。本申请具有在电机损坏或者外接电源中断时，人防门仍能正常启闭的效果。
