Door vane structure

Abstract

The invention relates to a door vane structure. An existing door vane is unable to open a car door latch hook through a landing door, causing inconvenience for opening the doors forcibly. The door vane structure provided by the invention comprises a base plate, a landing door lock component, a first door vane and a second door vane, and the landing door lock component comprises a door ball group; the second door vane is rotatably connected to the base plate through a second swing rod group, and the side, facing the second door vane, of the first door vane is provided with a clamping plate driven to horizontally extend and retract by the door ball group; and the side, facing the second door vane, of the clamping plate extends to form a pull rod used for hooking the second swing rod group to swing unidirectionally and driving the second door vane to move horizontally, and the base plate located at the side, back on to the first door vane, of the second door vane is provided with the car door lock component. Thus, a synchronous transmission structure that a landing door acts to trigger the car door lock component to unlock is formed, and the efficiency that operators open the door forcibly from the outside of the landing door is improved effectively; and the time for opening the door forcibly is shortened through simplifying the operation, and the safety of trapped persons is ensured.

Description

Technical field [0001] The invention relates to the field of elevators, in particular to a door knife structure. Background technique [0002] Elevators are widely used in high-rise buildings to facilitate the transportation of people or goods up and down. The existing elevator includes a car and landing doors on each floor. The car includes a car body and a car door that can be opened and closed. The car door is equipped with a door knife structure, and the landing door is equipped with a door with a floor door lock assembly. Hanging board, the door knife structure includes a door knife coordinated with the car door, the floor door lock assembly includes a goal ball group that can be clamped and opened by the door knife, the car door is opened by the door opening motor, and the linked door knife passes through the clamp Tighten the goal ball group to open the landing door lock assembly, and subsequently, the door knife will drive the landing door to open through the clamped goa...

AI Technical Summary

Problems solved by technology

The existing structure has the following defects: the car only has a one-way drive structure for opening the car door lock assembly and the floor door lock assembly through the car door. When opening the landing door, the landing door lock assembly needs to be opened manually through the triangular lock arranged on the outside of the landing door, and there is no structure for reversely controlling the opening of the car door lock assembly and the car door through the landing door, so that the landing door and the car door need to be opened independently The operations are completed separately, and the operation is troublesome. If there are trapped people in the car, the rescue time will be prolonged and the possibility of danger will be increased.
