Door plank structure

Abstract

The invention provides a door plank structure. The door plank structure comprises a door plank and a sill matched with the door plank for use, wherein the door plank comprises a door plank body; reinforcing ribs are arranged on the inner side of the door plank body; a left bent part, a right bent part, an upper bent part and a lower bent part are integrally formed with the door plank body; the left bent part comprises a first left bent edge and a second left bent edge; the right bent part comprises a first right bent edge and a second right bent edge; the upper bent part comprises a first upper bent edge and a second upper bent edge; and the lower bent part comprises a first lower bent edge and a second lower bent edge. The door plank structure has the beneficial effects that a light door plank structure is provided; the production operation is simple; the weight is light; the operation stability is good; the integral safety is higher; and the door plank structure can be prevented from slipping out of the sill.

Description

technical field [0001] The invention belongs to the technical field of elevator doors, and in particular relates to a door panel structure. 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 make the door panel too heavy...

AI Technical Summary

Problems solved by technology

[0003] The processing procedure of this kind of 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 of ungluing or welding between the upper and lower heads and the main body of the door panel.

In addition, the upper and lower heads made of 3mm thick general steel and the rib structure approximate to the height of the door panel make the weight of the door panel too heavy, resulting in the need to select a high-power door operator, resulting in unnecessary waste

At the same time, when the door panel is impacted by an excessive external force, the M8 bolts connecting the door panel and the guide shoes are easily loosened or broken, which will cause the door panel to fail to guide normally and even cause serious problems such as the door panel flying out of the sill
