The escape door lock comprises a main lock body, a heaven and earth lock and an unlocking device, the main lock body and the heaven and earth lock are each provided with a spring bolt, the unlocking device is connected with the main lock body, a transmission rod is arranged between the main lock body and the heaven and earth lock, lock cylinder rotating pieces are arranged in the main lock body and the heaven and earth lock respectively, and the lock cylinder rotating pieces can rotate around the axis in the vertical direction. The lock tongue is arranged on one side of the lock cylinder rotating piece, the unlocking device abuts against the other side of the lock cylinder rotating piece, protruding rods are arranged at the upper end and the lower end of the lock cylinder rotating piece respectively, a through hole is formed in the end of the transmission rod, and the protruding rods are inserted into the transmission rod through the through hole. The lock cylinder rotating piece in the main lock body drives the lock cylinder rotating piece of the heaven and earth lock to rotate through the transmission rod, and the spring bolt is driven to retract synchronously. According to the escape door lock, transmission is achieved through rotation, the action conversion frequency is reduced, the lock cylinder and a transmission structure are simplified, parts are reduced, the manufacturing cost is reduced, and the product competitiveness is effectively improved.
本发明公开了逃生门锁，包括主锁体、天地锁和开锁装置，主锁体和天地锁上分别设置有锁舌，开锁装置连接主锁体，主锁体和天地锁之间设置有传动杆，主锁体和天地锁内分别设置有锁芯转动件，锁芯转动件可绕上下方向的轴线转动，锁舌设置在锁芯转动件一侧，开锁装置抵接锁芯转动件另一侧，锁芯转动件上下两端分别设置有凸杆，传动杆的端部设置有通孔，凸杆通过通孔插入到传动杆内部，当开锁装置被触发时，主锁体中的锁芯转动件转动，主锁体中的锁芯转动件通过传动杆带动天地锁的锁芯转动件转动，带动锁舌同步缩回。本实施例的逃生门锁通过转动实现传动，减少动作转换的次数，简化锁芯和传动结构，减少零件，降低制作成本，有效提高产品竞争力。
