Elevator landing door pedal

Abstract

The invention provides an elevator landing door pedal, belongs to the technical field of machinery, and solves the problem that the existing elevator landing door pedal works unstably. The elevator landing door pedal comprises a basal body, wherein the basal body is provided with a sliding chute; the sliding chute divides the basal body into a connecting part I and a connecting part II in the width direction; a groove body is arranged on the lower side of the basal body; the cross section of the groove body is concave; a strip-shaped positioning part is arranged on each of the lower lateral surfaces of each of the connecting part I and the connecting part II; a strip-shaped connecting groove is formed in the lower end face of each of the positioning parts; two lateral parts of the groove body are inserted and connected into the corresponding connecting grooves; a connecting hole I penetrates through the lateral wall, away from the sliding chute, of each of the positioning parts; connecting holes II communicating with the connecting holes I are formed in lateral parts of the positioning parts; a cylindrical pin roll is inserted and connected in the connecting holes I and the connecting holes II; inner lateral walls of the connecting holes I and the connecting holes II are closely propped against the lateral wall of the pin roll; and lateral parts of the connecting holes I and the connecting holes II are fixed to the positioning parts through welding. The elevator landing door pedal has the advantage of working stability.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an elevator hall door pedal. Background technique [0002] As a vertical transportation tool for transporting passengers up and down between floors, elevators are extremely important to personal safety. The hall door (or landing door) pedal of the elevator is the key component used by passengers to enter and exit the floor and the elevator car, and it is also the guiding component for the frequent operation of the elevator door, so its required rigidity and strength are particularly important. [0003] For example, an elevator car door floor door pedal [application number: 200720109382.7; authorized announcement number: CN 201037089 Y] disclosed in the Chinese patent library, it is at least composed of aluminum alloy profiles, and its feature is that the lower part of the aluminum alloy profiles is connected with a steel structure The profile and the two are combined into one; th...

AI Technical Summary

Problems solved by technology

But there is still a problem in this elevator car door floor door pedal: in actual use, there is a chute on the aluminum alloy profile, and the elevator door is slidably connected in the chute. When the elevator door slides, the aluminum alloy profile has a tendency to shake, making the Friction occurs at the contact point between the aluminum alloy profile and the steel structure profile, and the wear of the contact point between the aluminum alloy profile and the steel structure profile will directly affect the reliability of the connection between the two, and then affect the working stability of the pedal, resulting in the pedal being in Working stability will become worse and worse under long-term use
