Abstract

The invention relates to the technical field of lifts, in particular to a lift door lock device. The lift door lock device comprises a left fastening rod, a right fastening rod, a car door lock assembly, a storey door lock assembly and a base. The base is connected with a car door. The left fastening rod, the right fastening rod and the car door lock assembly are all rotationally connected with the base. The left fastening rod and the right fastening rod are opposite. The storey door lock assembly is installed on a storey door and comprises a rolling wheel assembly. When the car door and the storey door are located on the same horizontal plane, the rolling wheel assembly is located between the left fastening rod and the right fastening rod, and the storey door lock assembly and the car door lock assembly are sequentially unlocked in the process that the right fastening rod is driven by a belt to move from the first position to the second position. According to the lift door lock device, the opening manner of a lift door is that the storey door lock and the car door lock are sequentially unlocked, and finally the car door lock and the storey door lock are opened in linkage; and in this way, the situation that the car door lock gets stuck when the car door is opened is avoided, the operation reliability of a lift is improved, and the attractiveness of the lift is improved. The invention further provides the lift.
