The invention relates to a civil air defense door locking device. The civil air defense door locking device comprises a locking mechanism, and the locking mechanism comprises a transmission shaft rotationally arranged in a door leaf. Transmission gears are fixed to the two ends of a transmission shaft. Transmission racks engaged with the transmission gears are arranged in the door leaf. One end ofeach transmission rack is provided with a lock head which is matched with a door frame in an inserting mode. A worm wheel is arranged in the transmission shaft. A driving shaft is rotationally arranged on the door leaf. A worm engaged with the worm wheel is arranged on the driving shaft. A sealing mechanism is arranged on the door leaf. The sealing mechanism comprises a rotating shaft rotationally arranged on the outer side of the door leaf and a sealing beam arranged on the rotating shaft. The driving shaft and the rotating shaft are connected through a synchronizing assembly. The synchronizing assembly comprises a first belt wheel arranged on the driving shaft, a connecting shaft rotationally arranged on the door leaf, a second belt wheel arranged on the connecting shaft and a synchronous belt arranged on the first belt wheel and the second belt wheel in a sleeving mode. A first bevel gear is arranged at one end of the connecting shaft. And a second bevel gear engaged with the firstbevel gear is arranged on the rotating shaft. The civil air defense door locking device has the effect of improving the locking efficiency of a civil air defense door.
本申请涉及一种人防门闭锁装置，其包括锁闭机构，锁闭机构包括转动设于门扇内的传动轴；传动轴两端均固定有传动齿轮；门扇内设有与传动齿轮相啮合的传动齿条；传动齿条一端均设有与门框插接配合的锁头；传动轴中部设有蜗轮；门扇上转动设有驱动轴；驱动轴上设有与蜗轮啮合的蜗杆；门扇上设有密封机构；密封机构包括转动设于门扇外侧的转轴和设于转轴上的密封梁；驱动轴和转轴通过同步组件连接；同步组件包括设于驱动轴上的第一带轮、转动设于门扇上的连接轴、设于连接轴上的第二带轮和套设于第一带轮和第二带轮上的同步带；连接轴一端设有第一锥齿轮；转轴上设有与第一锥齿轮啮合的第二锥齿轮。本申请具有提高人防门锁闭效率的效果。
