Description

A comprehensive performance elevator door panel

technical field

The invention belongs to the technical field of elevators, and in particular relates to an elevator door panel with comprehensive performance.

Background technique

Nowadays, there are more and more high-rise buildings, and elevators are basically installed in every high-rise building. The installation of elevators can greatly facilitate people's travel and facilitate the transportation of goods. With the popularization of elevators, more and more elevator accidents have occurred. Through investigation, it was found that the accident caused by violent damage to the elevator door accounts for a large part of the accident. The structural strength of the elevator door is poor and it is easy to be damaged. Moreover, the elevators in high-rise buildings also run faster, resulting in greater noise. The noise is easily transmitted directly into the car or into the waiting hall through the gap between the door panels, causing trouble for people in the two areas. In addition, there are more doors opened by elevators in high-rise buildings, and debris often falls into the grooves of each threshold. It takes a lot of time for maintenance personnel to clean the grooves each time.
