Elevator door plate

Abstract

The invention provides an elevator door plate, and belongs to the mechanical technical field. The elevator door plate solves the problem that an existing elevator door is short in service life. The elevator door plate comprises a long plate shaped body; one end of the body is equipped with an L-shaped step; a fireproof expanding and sealing strip is arranged in the step; the fireproof expanding and sealing strip is L-shaped and is parallel to the step; the fireproof expanding and sealing strip comprises a connecting part I which is horizontally arranged and a connecting part II which is vertically arranged; protruding buckles are arranged on each of the inner side surface of the connecting part I and the inner side surface of the connecting part II; the buckles are in the shape of long strip, and are arranged in the width direction of the body; blocking slots matched with the buckles are correspondingly formed in two step surfaces of the step; the buckles are embedded into the buckles; the inner side surface of the connecting part I and the inner side surface of the connecting part II tightly abut against the corresponding step surfaces separately; and protruding long-strip shaped sealing parts which are arranged in the width direction of the body is further arranged on the outer side surface of the connecting part I. The elevator door plate has the advantage of being long in service life.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an elevator door panel. Background technique [0002] At present, with the continuous development of the elevator industry and the improvement of safety awareness, the requirements for elevator landing door systems are getting higher and higher, and many of them require fire-proof doors. However, most of the fire-proof doors currently on the market have complex structures and cumbersome manufacturing processes. And because its forced closing device is arranged on the side of landing door, its installation space is larger, so the cost of whole fireproof landing door is higher, although also have some relatively simple fireproof doors of structure, its fire prevention effect is not ideal. [0003] For the above-mentioned problems, people have realized the deficiencies and made improvements, such as a fire-proof and smoke-proof elevator door [application number: 201420571948.8; autho...

AI Technical Summary

Problems solved by technology

However, there is still a problem with the elevator door: the fireproof expansion sealing strip is fixedly connected to the right door panel by glue, and after long-term use, it is prone to degumming, which will cause the sealing effect of the fireproof expansion sealing strip to decline or even disappear, affecting the use of the elevator door life
