Elevator door sheet structure matched with sill during use

Abstract

The invention provides an elevator door sheet structure matched with a sill during use. The elevator door sheet structure comprises a door sheet and the sill matched with the door sheet during use, wherein the door sheet comprises a door sheet body, reinforcing ribs, a left bent portion, a right bent portion, an upper bent portion and a lower bent portion; the reinforcing ribs are located on the inner side of the door sheet body; the left bent portion, the right bent portion, the upper bent portion, the lower bent portion and the door sheet body are formed integrally; the left bent portion comprises a first left bent edge and a second left bent edge; the right bent portion comprises a first right bent edge and a second right bent edge; the upper bent portion comprises a first upper bent edge and a second upper bent edge; and the lower bent portion comprises a first upper bent edge and a second lower hooked edge. The elevator door sheet structure has the benefits as follows: the production operation is simple, the weight is light, the operational stability is better, and the overall security is higher.

Description

technical field [0001] The invention belongs to the technical field of elevator doors, in particular to an elevator door panel structure used in conjunction with a sill. Background technique [0002] In the existing technology, the door panel of the elevator is composed of four main parts: the main body of the door panel, the upper head, the lower head, and the reinforcing rib. Or bonding and fixing together, after all is completed, connect the two guide shoes with the lower head through M8 bolts to maintain the normal guiding movement of the door panel. [0003] The processing procedure of this door panel structure is cumbersome, and the production time is long. When the elevator runs for a long time, it is easy to have quality problems such as ungluing or welding of the upper and lower heads and the main body of the door panel. In addition, the upper and lower heads made of general steel with a thickness of 3mm and the rib structure similar to the height of the door panel...

AI Technical Summary

Problems solved by technology

[0005] The first problem with the aluminum profile sill with this structure is that when the aluminum profile sill is directly fixed, due to the low strength and hardness of the material, it is easily damaged and deformed when it is hit by an external force

The second problem is that when the door panel is hit by an external force, the M8 bolts connecting the door panel and the door guide shoe are easily loosened or broken, which will cause the U-shaped guide groove to not guide the door panel to move normally, or even the door panel to fly out of the sill Serious Problem
