Elevator car door locking device and elevator equipment

An elevator car door locking device, comprising:

• a vane base provided with a first rotation center and a second rotation center;
• a vane assembly mounted on the vane base and provided with a clamping vane or an expanding vane, and
• a vane drive assembly mounted on the vane base and having a driving member, a transmission member, an unlocking member and a car door locking hook, wherein the driving member, the transmission member and the vane assembly are hinged to the first rotation center, the car door locking hook is hinged to the second rotation center and has a locked state and an unlocked state, the transmission member is further hinged with the vane assembly through a connecting shaft, and the unlocking member is hinged to a third rotation center on the driving member and is provided with a limiting part for limiting the connecting shaft, wherein the driving member, when driven to move, drives the driving member, the connecting shaft and the unlocking member to rotate around the first rotation center toward a first direction or an opposite second direction,
• wherein, when the vane assembly is not in contact with a landing door locking ball, the connecting shaft is located at a first limit position on the unlocking member and drives the vane assembly to open or close, and the unlocking member swings along an arc-shaped part on the car door locking hook;
• when the vane assembly is in contact with the landing door locking ball and is restricted in movement, the connecting shaft rotates to a second limit position on the unlocking member, and the unlocking member swings around the third rotation center to offset the arc-shaped part by a displacement, so that the car door locking hook rotates around the second rotation center toward the first direction until reaching the unlocked state, or rotates toward the second direction until reaching the locked state;
• wherein the limiting part is a waist-shaped hole, and/or the arc-shaped part is a chute with an arc-shaped contour arranged on the car door locking hook.
