Abstract

The invention discloses a connecting rod type elevator door switch, comprising: an elevator door frame, on which a driving device and an elevator car door are installed on the elevator door frame through a guide rail assembly, and is characterized in that: between the driving device and the elevator door frame There is a connecting rod device between the elevator car doors. The connecting rod device is hinged sequentially by a rocker, a connecting rod, and a push rod. The ends of the rocker and the push rod are respectively connected with the connecting rod device and the elevator car door; The connecting rod described above is hingedly installed on the elevator door frame, and a straight rod is also hinged on the connecting rod, and the end of the straight rod is hinged with the elevator car door. The technical structure adopted in the present invention is simple and practical, can reduce power consumption, and is cheap, and the multi-linkage adopted can make the brake of the elevator door more stable and fast, and is convenient for daily maintenance.

Description

technical field [0001] The invention relates to a door switch device, in particular to a link type elevator door switch. Background technique [0002] The elevator door is a very important part of the elevator. There are two doors. The one that can be seen from the outside of the elevator and is fixed on each floor is called the hall door, and the one that can be seen inside and fixed on the car moves with the car is called the car door. . The switch of the elevator door is generally driven by the car door to switch the hall door. Its stability, rationality and safety are the key factors to determine the elevator grade. [0003] In today's technology, elevator doors often appear 1. The elevator can neither close nor open the door. 2. After reaching the leveling floor of the station, the elevator door will not open. 3. Press the door close button, the door will not close. 4. The elevator has received the floor selection signal, the door is closed, but it cannot start. 5...
