The invention belongs to the technical field of elevator landing door locks, and particularly relates to a safety type elevator landing door lock device which comprises a lock hook assembly and a lock gear assembly, a lock hook of the lock hook assembly is in limiting fit with a lock gear of the lock gear assembly through a limiting block, a telescopic block is slidably connected into the limiting block, and the telescopic block is in limiting fit with the lock gear after stretching out; the telescopic block is in transmission connection with a driving part. During use, when the lock gear and the lock hook are in a meshed limiting state, the telescopic block in the limiting block stretches out and is buckled below the lock gear, and the situation that people are injured due to the fact that an elevator landing door is accidentally opened due to the fact that the meshing depth is insufficient due to the fact that a door lock is not completely closed is prevented.

    本发明属于电梯厅门门锁技术领域,尤其涉及一种安全式电梯层门门锁装置,包括锁钩组件和锁档组件,锁钩组件的锁钩与锁档组件的锁档通过限位块限位配合,限位块内滑动连接有伸缩块,伸缩块伸出后与锁档限位配合;伸缩块传动连接有驱动部。使用时,当锁档和锁钩处于啮合的限位状态时,限位块内的伸缩块伸出,扣在锁档的下方,防止由于门锁未完全闭合所导致的啮合深度不足,从而使电梯厅门意外打开造成人员受伤等情况。
