The escape door lock comprises a main lock body, a rotating piece, a spring bolt, a safety assembly and an unlocking mechanism, and the main lock body is provided with an inner cavity; the rotating piece can rotate around a vertical axis, and the rotating piece is provided with a rotating part; the spring bolt is provided with a driven part, and when the rotating piece rotates, the rotating part can push the driven part to enable the spring bolt to retract; the safety assembly comprises a blocking piece and a shifting rod, the blocking piece is arranged in the spring bolt and can move up and down, a first sliding groove is formed in the blocking piece, a blocking rod extending downwards is arranged on the lower portion of the blocking piece, a first through hole is formed in the lower portion of the spring bolt, the blocking rod penetrates through the first through hole, and the blocking rod abuts against the side, close to the spring bolt, of the rotating part. The shifting rod can move towards the interior of the spring bolt along the first sliding groove and push the blocking piece to move upwards. According to the escape door lock provided by the embodiment of the invention, a reliable safety effect can be realized through a simple structure principle, the process is simplified, and the manufacturing cost is reduced.
本发明公开了一种逃生门锁，包括主锁体、转动件、锁舌、保险组件和开锁机构，主锁体设置有内腔；转动件可绕竖向的轴线转动，转动件设置有转动部；锁舌设置有从动部，转动件转动时，转动部能够推动从动部以使锁舌缩回；保险组件包括阻挡件和拨杆，阻挡件设置于锁舌内并能够上下移动，阻挡件设置有第一滑槽，阻挡件的下部设置有向下延伸的阻挡杆，锁舌的下部设置有第一通孔，阻挡杆穿过第一通孔，并且阻挡杆抵接转动部靠近锁舌的一侧，锁舌缩回时，拨杆能够沿第一滑槽向锁舌内移动并推动阻挡件向上移动。本发明实施例提供的逃生门锁能够通过简单的结构原理实现可靠的保险作用，简化了工艺，降低了制造成本。
