The elevator is a mechanical device for vertically lifting and transporting people and objects between different floors in a hoistway of a building, and landing doors leading to a car are arranged at each landing so that the people and the objects can be conveniently transported in and out of the car. When the cage is not stopped at the called hall, all landing doors are in a closed state; when the cage stops at the hall to be called, only the hall landing door to be called can be opened, and the rest is in a closed state. In order to ensure the effective closing and locking of the landing door, an elevator door lock is required to be installed on the landing door. The landing door lock is used for realizing the closing and locking verification of the landing door and mainly comprises a main door lock, an auxiliary door lock and an electric safety loop. The main door lock is used for verifying the locking of the landing door, and when the depth of engagement between the locking hooks of the main door lock is at least 7mm, the locking strength of the landing door meets the safety requirement.
