Description

Technical Field

[0001] The utility model belongs to the technical field of linkage doors, and particularly relates to a low-track linkage door. Background Art

[0002] The low-track interlocking door is a common automatic door system, which is usually used in commercial buildings and public places. It consists of a series of door leaves that can be opened and closed automatically to facilitate the entry and exit of people. The characteristics of the low-track interlocking door include safety and reliability, space saving, easy installation and maintenance, etc. The low-track interlocking door in the prior art is mostly composed of multiple groups of door leaves, and a ladder-type track arrangement is used as a way to open multiple groups of door leaves. This design requires sufficient space for the door body to move when opening and closing, which will cause the door body to move inward when opened, occupying more indoor space, affecting the passage and layout design, and affecting the aesthetics of the interior. Therefore, it is hoped to propose a new structure to solve the above problems. Utility Model Content
