Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator door knife transmission device. Background technique [0002] Elevators can be divided into two types, one is a vertical lift powered by an electric motor, equipped with a box-shaped gondola, which is used for multi-storey buildings to take advantage of people or carry goods. The other is a step type, the tread plate is installed on the crawler belt and runs continuously, commonly known as an automatic elevator. The fixed lifting equipment serving the specified floors has a car running between at least two vertical or rigid guide rails with an inclination angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. For this type of vertical elevator, in order to ensure the safety of the passengers, the elevator car is equipped with a hall door, which is connected by a door knife set on the top of the c...
