Abstract

The invention discloses a car door lock coupler device. By arranging a rocker, the car door lock coupler device utilizes the interaction between a driving belt of a door machine motor and a rocker restoring spring to control the swing of the rocker and then controls the opening and closing of a car door in combination with the action of a left door ball and a right door ball at the landing door side. The invention integrates a car door lock function into car door couplers, a shaft ramp does not need to be arranged at each storey, installation accuracy is not required as well, and installation and debugging man-hours are reduced. The car door lock coupler device is an invented device which is convenient to mount and use and can bring high economic benefit, and the car door lock coupler device is not affected by the opening width and the opening height, is highly universal and has a wide application range.

Description

technical field [0001] The invention relates to a mechanical device for realizing locking of an elevator car door, in particular to a car door locking knife device. Background technique [0002] In the current market products, no matter whether the elevator is running or stopped, the people in the car can open the car door with a force of about 20kg. Accidents in which items fell into the well occurred. Therefore, in order to avoid such accidents, it is generally chosen to install car door locks. The current car door locks need to install an unlocking bow on each floor. There are high requirements for on-site commissioning and installation, especially when there are many floors, it takes a lot of energy. [0003] In order to avoid the need to install an unlocking bow on each floor, the Chinese patent authorization announcement No. CN201864431U discloses a device for combining two locks for elevator car doors, which includes left and right door knife arms, a linkage mechani...
