Civil air defense door for positioning and sealing door leaf
The civil air defense door comprises the door leaf and a door frame, a hand wheel is arranged in the middle of the outer surface of the door leaf, a threaded rod is fixedly arranged at the rear end of the hand wheel, a locking assembly is arranged in the door leaf and meshed with the threaded rod, and two longitudinally-arranged transmission shafts a are arranged in the locking assembly; the hand wheel rotates to drive the transmission shaft a to lock the door leaf and the door frame, a rolling wheel for supporting the door leaf is arranged at the position, away from the hinge, of the lower end of the door leaf, the rolling wheel rotates to drive the lubricating assembly arranged in the door leaf to lubricate the hinge, and the locking assembly drives the sealing assembly to extrude the door crack in the locking process. The rolling wheels are arranged at the lower end, away from the hinges, of the civil air defense door, the civil air defense door is supported, the heavy civil air defense door is more convenient and faster to open and close, friction between the door leaf and the hinges is reduced, and the problems that the civil air defense door is inconvenient to open and close, the door leaf is prone to abrasion, and the sealing performance is poor due to the fact that the civil air defense door is thick and heavy are solved.
本发明涉及一种用于门扇定位及密封的人防门，包括门扇及门框，门扇外表面居中设置有手轮，手轮后端部固定设置有螺纹杆，门扇内部设置有锁紧组件且与螺纹杆相啮合，锁紧组件内包括有两条纵向设置的传动轴a，手轮转动带动传动轴a对门扇与门框进行锁紧，门扇下端部远离合页处设置有对门扇起支撑作用的滚轮，滚轮转动驱动设置在门扇内部的润滑组件对合页进行润滑处理，锁紧组件在锁紧的过程中驱动密封组件向门缝处挤压。本发明通过在人防门远离合页处的下端部设置有滚轮，对人防门起支撑作用，让厚重的人防门在开合的过程中更加方便快捷，并减少了门扇与合页间的摩擦，解决了人防门因厚重而开合不便、门扇易磨损、密封性差的问题。
