Internal-lockable explosion-proof civil defense door
The invention discloses an internal-lockable explosion-proof civil defense door. The internal-lockable explosion-proof civil defense door comprises a door frame part and a door body part, wherein thedoor body part is arranged in the middle of the door frame part. When the internal-lockable explosion-proof civil defense door is used, a front hand wheel is manually rotated to enable a gear to rotate, so that a sleeve clamp is driven to rotate to drive a rotating wheel to rotate; and the rotating wheel is rotated to drive a cambered slide block to slide so as to drive a locking rod to move outwards, and thus the locking rod extends out of an extending hole and is inserted into a locking hole to lock the civil defense door. When the internal-lockable explosion-proof civil defense door needs to be opened, the front hand wheel is rotated anticlockwise to reset the rotating wheel, and the cambered slide block is reset through a reset spring, so that the situation that the locking rod is difficult to reset is avoided; and a rear hand wheel is manually pulled outwards to enable a gear sleeve inside the sleeve clamp to be disengaged with the gear, and then the civil defense door can not beopened by rotating the front hand wheel from the outside, so that the civil air defense door is locked and is only opened from the inside, and the safety is improved.
本发明公开一种可内锁式防爆人防门，包括：门框部分、门体部分，门体部分安装在门框部分中间位置，使用时，通过手动转动前手轮使齿轮转动，从而带动套卡转动进而带动转轮转动，通过转轮转动从而带动弧面滑块滑动进而带动锁定杆向外移动，使锁定杆从伸出孔伸出插入锁定孔中进而将人防门锁定；当需要打开时，通过逆时针转动前手轮进而使转轮复位，通过复位弹簧将弧面滑块复位，避免了锁定杆难以复位的情况发生；通过手动向外拉动后手轮使套卡内部的齿轮套与齿轮脱离，进而从外边转动前手轮不能打开人防门，使人防门锁定，只能从内部打开，增加了安全性。
