The invention discloses a mechanical self-locking type landing door lock structure and a landing door, and the mechanical self-locking type landing door lock structure comprises a cage collision iron which is mounted on a cage of a lifter; the landing door assembly comprises a door frame and a landing door body installed on the door frame, and the landing door body can be opened and closed; the door lock assembly comprises a rotating baffle mechanism and a limiting stopper mechanism, the rotating baffle mechanism and the limiting stopper mechanism are both installed on the door frame and located above the landing door body, the rotating baffle mechanism is matched with the cage collision iron through a nylon roller to rotate, and the landing door body is locked or unlocked through a limiting plate. When the rotating baffle mechanism unlocks the landing door body, the limiting stopper mechanism enables the suspension cage to stop running through the limiting stopper. The mechanical self-locking type landing door lock structure is high in overall structure stability, low in failure rate, high in reliability, good in mechanical self-locking safety, capable of limiting operation of a suspension cage and good in protection effect.
