The invention belongs to the field of lock bodies, and relates to an emergency darkroom lock body which comprises a lock shell and a spring bolt, the tail end of the spring bolt is connected with a spring bolt plate, the spring bolt swings front and back with the front wall and the rear wall of a spring bolt hole as fulcrums, an impact elastic piece is further arranged in the lock shell, the rear end of the impact elastic piece abuts against the inner wall of a rear shell, and the front end of the impact elastic piece abuts against the rear end face of the spring bolt plate. The impact elastic piece always exerts forward pressing force on the spring bolt plate; a rotary knob is rotationally arranged in the lock shell and arranged on the side, away from the lock tongue, of the lock tongue plate, the rotary knob extends towards the lock tongue plate to form an abutting end, when a door is locked, the abutting end abuts against the tail end face of the lock tongue plate, an extension spring is arranged on the lock tongue, a spring fixing column is sleeved with one end of the extension spring, and the rotary knob is sleeved with the other end of the extension spring. The device has the advantages that the structure is simple, the concealment is high, the door can be locked indoors, and the device can be repeatedly used.
本发明属于锁体领域，涉及一种应急暗室锁体，包括锁壳和锁舌，所述锁舌的尾端连接有锁舌板，锁舌以锁舌孔前后壁为支点前后摆动，所述锁壳内还设有撞击弹片，撞击弹片的后端抵在后壳内壁，撞击弹片的前端抵在锁舌板后端面上，撞击弹片始终给予锁舌板向前压的力；所述锁壳内转动设置有转扭，转扭设置在锁舌板远离锁舌的一侧，所述转扭朝向锁舌板延伸出抵制端，锁门时，抵制端抵在锁舌板的尾端面，所述锁舌上设有拉伸弹簧，拉伸弹簧的一端套设在弹簧固定柱上，另一端套设在转扭上，拉伸弹簧始终给予锁舌缩回锁壳的力，该装置有结构简单，隐蔽性高，从屋内可锁门，并且可重复使用的优点。
