Double sub-frame structure of electric telescopic door row

Abstract

The invention relates to a double-auxiliary-frame structure of a door row of an electric retractable door, which comprises a door row formed by movably connecting a plurality of main frames, a plurality of auxiliary frame assemblies and a plurality of crossed connection rods for connecting the main frames and the auxiliary frame assemblies. Each auxiliary frame assembly comprises a first auxiliaryframe and a second auxiliary frame; the first auxiliary frames and the second auxiliary frames are arranged in parallel and at intervals; the first auxiliary frames and the second auxiliary frames are respectively in rotational and sliding connection with the crossed connection rods; when the door row retracts, the crossed connection rods retract into the auxiliary frame assemblies, and the auxiliary frame assemblies retract into the main frames, so that the main frames, the auxiliary frame assemblies and the crossed connection rods are attached mutually and compactly into one whole body witha small space proportion. According to the invention, due to arrangement of the double-auxiliary-frame structure, when being expanded, the door row of the electric retractable door is compact and full; when the door row retracts, an arrangement field for the electric retractable door can be saved to the greatest extent, and after retraction, the door row is more compact and tidy. In another aspect, the auxiliary frame assemblies are connected with the crossed connection rods by buckles, and thus, the double-auxiliary-frame structure not only is simple in structure, but also is convenient andrapid to assemble.

Description

【Technical field】 [0001] The invention relates to an electric telescopic door, in particular to an electric telescopic door door row double sub-frame structure which is compact and full when the door row is opened, has the smallest space ratio after the door row shrinks, has a simple structure and is easy to install. 【Background technique】 [0002] Electric telescopic doors are favored by people because of their flexible, easy-to-manipulate, and changeable shapes. They are widely used in institutions, schools, enterprises, stadiums, etc., and can effectively manage vehicles and personnel entering and leaving. . The traditional electric telescopic door row is connected by the main frame, the sub-frame and the cross-link. The simple superimposed structure of the main frame, the sub-frame and the cross-link makes the door row not compact and full when it is unfolded. Longer length when shrunk into place. And if the retractable length of the door row is too long, it will occup...

AI Technical Summary

Problems solved by technology

The traditional electric telescopic door row is connected by the main frame, the sub-frame and the cross-link. The simple superimposed structure of the main frame, the sub-frame and the cross-link makes the door row not compact and full when it is unfolded. Longer length when shrunk into place

And if the retractable length of the door row is too long, it will occupy the opening width of the telescopic door, which requires enough space

However, for large cities where the current land resources are scarce, the use of existing electric telescopic doors is limited due to the constraints of site space and area.
