[0002] In the field of sliding door design, linked doors are highly favored for their unique synchronized opening and closing function, and are widely used in high-end venues such as lobbies and exhibition halls, providing users with an elegant and convenient entry and exit experience. Linked doors typically consist of multiple door panels that move along their own independent tracks and achieve synchronized opening and closing through precise linkage devices (such as belts, pulleys, and linkage components).

[0003] However, a significant technical challenge exists in traditional linkage door designs: the placement of the linkage mechanism and the load-bearing rollers. The traditional approach is to place the linkage mechanism on the lower side of the door leaf, while the load-bearing rollers, typically hanging rollers, are placed on the upper side. While this design satisfies the basic functional requirements of a linkage door to some extent, it inevitably leaves a gap between the upper track and the door leaf.

[0004] When the interlocking door is used as a lobby door, this gap not only affects the overall aesthetics but also brings additional problems. First, the gap may allow light to pass through, ruining the overall visual effect of the door.
