The invention discloses an escape fire-resistant lock. The escape fire-resistant lock comprises a lock tongue torsion mechanism, a lock pin torsion mechanism and a shell mechanism, the lock tongue torsion mechanism comprises an inner handle, an inner rotating lock cylinder rod is arranged on one side of the inner handle, a first rotating block is arranged on one side of the inner rotating lock cylinder rod, a rotating block is arranged on one side of the first rotating block, a rotating block is arranged on one side of the rotating block, a second rotating block is arranged on one side of therotating block, a first fixing block is arranged on one sides of the upper parts of the first rotating block and the second rotating block, a second fixing block is arranged on the other sides of theupper parts of the first rotating block and the second rotating block, both the middle of the first fixing block and the middle of the second fixing block are provided with circular holes, movable rods are arranged in the circular holes, springs are arranged on the movable rods, lock tongues are arranged on one sides of the springs, and closing blocks are arranged in the middles of the lock tongues. The unlocking effect can be achieved only by directly rotating the handle during escaping, the escape possibility is increased, and the purpose of the fire-resistant lock is achieved better.
本发明公开了一种逃生防火锁，所述逃生防火锁包括锁舌扭转机构和锁销扭转机构与壳体机构，所述锁舌扭转机构包括内把手，所述内把手一侧设有内转动锁芯杆，所述内转动锁芯杆一侧设有第一转动块，所述第一转动块一侧设有转动片，所述转动片一侧设有转动片一侧设有第二转动块，所述第一转动块与第二转动块上部一侧设有第一固定片，所述第一转动块与第二转动块上部另一侧设有第二固定块，所述第一固定块与第二固定块中部都设有圆孔，所述圆孔中设有移动杆，所述移动杆上设有弹簧，所述弹簧一侧设有锁舌，所述锁舌中部设有关闭块，本发明在逃生时直接转动把手，即可达到开锁效果，增加了逃生可能性，更符合防火锁的用途。
