DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-3 The utility model provides a single-axis adjustable hanging wheel structure, including a connecting frame 101 and a connecting seat 2. The connecting seat 2 is connected to two sets of pulley bodies 102 through single-axis rotation. The connecting seat 2 and the connecting frame 101 are connected and fixed by a connecting component. The connecting seat 2 is provided with a mounting component for fixing to the upper end of the sliding door, and the connecting seat 2 is provided with an adjustment component for lifting and lowering adjustment after installation.

[0018] It should be noted here that: during the process of assisting the movement of the movable door, the hanging wheel structure, through the structure of the single-axis double pulley body 102, can reduce the length of the entire structure and the number of pulley bodies 102 during the process of assisting the movement of the movable door, thereby further reducing the cost of the product and facilitating a smoother and more stable sliding operation of the movable door.

[0019] The mounting assembly includes a slide plate 501 slidably connected to the connecting seat 2, a plug plate 502 is fixed to the lower end of the slide plate 501, and the plug plate 502 is plug-connected to the upper end of the movable door and fixed by fixing bolts;

[0020] It should be noted here that: when the hanging wheel structure assists the moving door in moving, the plug plate 502 below the connecting seat 2 is plugged and connected to the upper end of the moving door and fixed by fixing bolts.

[0021] The adjustment assembly includes a V-shaped groove 601 formed on the slide plate 501, and a squeeze bolt 602 is threadedly connected to the connecting seat 2 for pressing against the V-shaped groove 601;

[0022] It should be noted here that: by the counteraction between the extrusion bolt 602 and the V-shaped groove 601, the slide plate 501 is driven to move upward, which further facilitates the adjustment of the usable height of the installed movable door.

[0023] The connecting assembly includes a connecting plate 301, which is provided with a T-slot 302, a T-plate 303 being slidably connected to the T-slot 302, the T-plate 303 being fixed to one side of the connecting seat 2, and a connecting bolt 304 being threadedly connected to the connecting plate 301 for abutting and squeezing the T-plate 303. The connecting plate 301 is fixedly connected to the connecting frame 101 via a fixing assembly;

[0024] It should be noted here that: through the sliding cooperation between the T-slot 302 on the connecting plate 301 and the T-plate 303, the use position of the connecting seat 2 can be adjusted up and down. After the position is adjusted, the adjusted state is limited by the mutual extrusion effect between the connecting bolt 304 and the T-plate 303.

[0025] The fixing assembly includes a fixing plate 401 that is slidably connected to the connecting frame 101. The fixing plate 401 is fixed to one side of the connecting plate 301.

[0026] It should be noted that the cooperation among the fixing plate 401 , the through-hole 402 and the fixing pin 403 facilitates the installation and fixation of the auxiliary connecting plate 301 and the connecting frame 101 .

[0027] Working principle: In the process of assisting the movement of the sliding door, the hanging wheel structure inserts and connects the plug plate 502 under the connecting seat 2 with the upper end of the sliding door and fixes it with fixing bolts. After installation and connection, the connecting seat 2 will not be subjected to force and deflected in the horizontal direction. Therefore, only a single-axis double-pulley body 102 structure needs to be set on the connecting seat 2 to achieve stable movement operation of the sliding door. Through the structure of the single-axis double-pulley body 102, firstly, the length of the entire structure is reduced, which is convenient for the installation and use of the sliding door in a narrow space. Secondly, the number of pulley bodies 102 is reduced, further reducing the cost of the equipment. Finally, the reduction in the number of pulley bodies 102 facilitates smoother and more stable sliding operation of the mobile door.
