Description

Technical Field

[0001] The utility model relates to the technical field of sliding doors, in particular to a ghost door pulley guide rail device. Background Art

[0002] The hidden track sliding door is a hidden track door. Its design concept is to completely integrate the track and the door panel so that when the door moves, the track moves with it, thus realizing the hiding of the track.

[0003] This design is not only beautiful, but also solves the problems of traditional doors with exposed hardware and difficulty in cleaning.

[0004] Specifically, the track of the ghost door is installed behind the door, and the movement of the track is driven by the movement of the door panel, thereby hiding the track.

[0005] This design allows the door panel to move with the track no matter where it reaches, thus hiding the track. In addition, since the main bracket pulley moves inside the track, the door panel covers the track as well as the main bracket pulley, further enhancing its concealment.

[0006] The track of the traditional ghost door is set in the horizontal plane, and the main bracket pulley contacts the track in the vertical direction. Since the ghost door is prone to errors during the installation process, the main bracket pulley may derail and the various pulleys may be unevenly stressed.

[0007] The main bracket pulley of the traditional ghost door is directly installed on the cabinet / wall. If the positioning is inaccurate during the installation process, it is easy for the ghost door's slide rail to be unable to align with the pulley.

[0008] The main bracket pulley of the traditional ghost door cannot adjust the position of the pulley, which can easily cause the door panel to shake during movement.

[0009] Therefore, we propose a ghost door pulley guide device to solve the above problems. Utility Model Content
