Abstract

The invention provides a door vane of an elevator door and an unlocking device. The door vane of the elevator door includes a door vane bottom plate, a left blade, a right blade, a lower crank arm assembly and a latch hook assembly. The left blade is installed on one side of the door vane bottom plate in the vertical direction and hinged to the door vane bottom plate through a connecting rod. Theright blade is installed on the other side of the door vane bottom plate in the vertical direction and the upper end of the right blade is hinged to the latch hook assembly and the door vane bottom plate through a rotation shaft. The lower end of the right blade is hinged to the lower bending arm assembly and the door vane bottom plate through a rotation shaft. The upper end of the left blade is provided with a rolling wheel. The latch hook assembly is elastically connected with the door vane bottom plate through a small tension spring. Through the adoption of the technical scheme, an elevatorcar is improved in terms of security and economy, the door vane can gradually replace an existing traditional door vane product, the latest standard requirements and the industry development trend are met and the wide application prospect is achieved; and the door vane of the elevator door is simple in structure, easy to install, low in cost and convenient to maintain.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to an elevator car door knife and an unlocking device. Background technique [0002] The elevator car door unlocking device is a necessary part of the existing elevator safety maintenance, and plays a safe role in the maintenance and operation of the car; the existing elevator door knife and unlocking device have a relatively complicated structure and high cost, and are practical for a long time. The rear safety performance cannot be guaranteed; and the existing unlocking device needs a special tool to open, and sometimes when it needs to be opened for an emergency, the car door cannot be opened manually, and the operation is not humanized enough. [0003] Based on the above-mentioned technical problems in the elevator door unlocking device, there is no related solution; therefore, it is urgent to find an effective solution to solve the above-mentioned problems. Cont...
