Electric retractable door structure that can shrink the door row

Abstract

An electric telescopic door structure capable of shrinking and shrinking the door row. The structure includes a machine head and a door row. Accommodate the U-shaped accommodation frame at the front of the door row. The main frame includes the first main frame, the second main frame and the wheelless main frame. . When the door row shrinks, its front part enters the accommodation frame at the lower end of the machine head, and the main frame, sub-frame and cross-link are matched with each other through the shrinkage structure, so that the main frame, sub-frame and cross-link are closely attached to each other. A whole with a small space ratio is synthesized, and several large traveling wheels of the second main frame are close to each other, and several small traveling wheels of the first main frame are misplaced and arranged inside several large traveling wheels. The present invention can reduce the space proportion of the retracted electric telescopic door, save the installation site of the electric telescopic door to the greatest extent, and has both practicability and ornamental value.

Description

[0001] 【Technical field】 [0002] The invention relates to an electric telescopic door, in particular to an electric telescopic door structure capable of shrinking the door row to a minimum space ratio after the door row shrinks. [0003] 【Background technique】 [0004] At present, electric telescopic doors are favored by people for their flexible expansion and contraction, easy manipulation and changeable shapes, and are widely used in institutions, schools, enterprises, stadiums and other places, and can effectively manage vehicles and personnel entering and leaving. . The traditional electric retractable door includes a machine head and a retractable door row driven by the machine head, wherein the door row is connected by a main frame, a sub frame and a cross link. The door row of the traditional telescopic door is as wide as the machine head, and its main frame, sub-frame and cross-connecting rods are multiplied into a simple superimposed structure, which makes the length...

AI Technical Summary

Problems solved by technology

The door row of the traditional telescopic door is as wide as the machine head, and its main frame, sub-frame and cross-connecting rods are multiplied into a simple superimposed structure, which makes the length of the door row longer after shrinking in place. In many cases, the electric telescopic door The setting of the door will be restricted by the space and area of ​​the site. When the electric telescopic door shrinks in place, it indicates that the telescopic door is fully opened. At this time, if the length of the telescopic door is too long, it will occupy the opening width of the telescopic door. It is extremely unreasonable for a large city
