Description

Technical Field

[0001] The utility model relates to the technical field of lower pulley structures, in particular to a pulley structure for preventing glass from sagging. Background Art

[0002] The sliding rail of a sliding door is used as a sliding guide for the door. The door body is connected to a pulley structure that is slidably connected to the rail. Usually, the rail is fixedly connected to the door frame. The door body is supported by the pulley structure. However, during the installation process, due to the deviation of the overall size of the glass or the size of the connection hole or long-term use, the glass may "sag", increasing the gap between the upper edge of the door body and the door frame, making the glass door loose and the sliding of the door unstable. Utility Model Content

[0003] The utility model aims to provide a pulley structure for preventing glass from sagging in view of the defects and shortcomings of the prior art.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] The utility model discloses a pulley structure for preventing glass from sagging, which comprises a pulley bracket and a pulley arranged on the pulley bracket; the pulley bracket is connected with an inner shaft; a positioning plate is fixed on the inner shaft;

[0006] An eccentric hole is arranged at an eccentric position of the inner shaft; a rotating shaft matching the eccentric hole is arranged on the pulley bracket; the rotating shaft is inserted into the eccentric hole; and the inner shaft is locked and fixed on the pulley bracket by a locking piece.

[0007] Furthermore, the locking member is a locking bolt; an internal threaded hole is provided on the rotating shaft; and a countersunk hole is provided on the inner shaft.

[0008] Furthermore, a plurality of tooth grooves are evenly distributed on the end surface of the inner shaft; the tooth grooves are distributed in a circumference along the eccentric hole; and teeth meshing with the tooth grooves are provided on the pulley bracket.

[0009] Furthermore, a second gasket and a first gasket are arranged on the inner shaft.

[0010] Furthermore, a decorative cover is provided on the positioning plate; a positioning hole is provided on the decorative cover; a concave ring is provided on the side wall of the positioning plate; a rubber ring is embedded and fixed on the concave ring; after the positioning plate is embedded in the positioning hole, the outer wall of the rubber ring is pressed against the side wall of the positioning hole.

[0011] After adopting the above structure, the beneficial effects of the utility model are as follows: the pulley structure for preventing glass from sagging described in the utility model, when the utility model is used, the inner shaft cannot rotate when the locking piece is locked, so that the glass door and the pulley bracket are fixed; when the height of the glass door needs to be adjusted, the locking piece is loosened so that the inner shaft can rotate around the rotating shaft, because the inner shaft and the rotating shaft are eccentric structures; therefore, rotating the inner shaft can adjust the relative height between the axis of the inner shaft and the axis of the rotating shaft, and then adjust the height of the glass door, and the locking piece is locked again after the adjustment; this mechanism can realize the height adjustment of the glass door on the pulley bracket, and adjust the gap between the glass door and the door frame, so that the door gap is reduced and the sliding of the door is more stable.

[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] like Figures 1 to 6As shown, the pulley structure for preventing glass from sagging described in the utility model comprises a pulley bracket 1 and a pulley 2 arranged on the pulley bracket 1; the pulley bracket 1 is connected with an inner shaft 5; a positioning plate 501 is fixed on the inner shaft 5; a positioning sleeve 3 is rotatably connected to the outer side of the inner shaft 5; the hole position opened in the glass door A is equal to the hole position of the outer circle of the positioning sleeve 3, and after the positioning sleeve 3 is inserted into the hole position of the glass door A, the positioning plate 501 clamps and fixes the glass on the pulley bracket 1;

[0025] The eccentric position of the inner shaft 5 is provided with an eccentric hole 503; the pulley bracket 1 is provided with a rotating shaft 102 matching the eccentric hole 503; the rotating shaft 102 is inserted into the eccentric hole 503; the inner shaft 5 is locked and fixed to the pulley bracket 1 by a locking piece 6; the inner shaft 5 cannot rotate when the locking piece 6 is locked, so that the glass door A is fixed to the pulley bracket 1; when the height of the glass door A needs to be adjusted, the locking piece 6 is released so that the inner shaft 5 can rotate around the rotating shaft 102. Because the inner shaft 5 and the rotating shaft 102 are eccentric structures, the relative height between the axis of the inner shaft 5 and the axis of the rotating shaft 102 can be adjusted by rotating the inner shaft 5, and then the height of the glass door A can be adjusted. After the adjustment, the locking piece 6 is locked again; this mechanism can realize the height adjustment of the glass door A on the pulley bracket 1, and adjust the gap between the glass door A and the door frame, so that the door gap is reduced and the sliding of the door is more stable.

[0026] As a preferred embodiment of the utility model, the locking member 6 is a locking bolt; an internal threaded hole 102a is provided on the rotating shaft 102; a countersunk hole is provided on the inner shaft 5; the locking bolt passes through the countersunk hole and is threadedly connected in the internal threaded hole 102a; the locking bolt is used as a locking member between the inner shaft 5 and the rotating shaft 102 for easy loosening.

[0027] As a preferred embodiment of the present invention, a plurality of tooth grooves 502 are evenly distributed on the end surface of the inner shaft 5; the tooth grooves 502 are distributed circumferentially along the eccentric hole 503; the pulley bracket 1 is provided with teeth 101 meshing with the tooth grooves 502; when the inner shaft 5 is locked and fixed on the pulley bracket 1 by the locking member 6, the teeth 101 are inserted into the tooth grooves 502 for positioning, so that the inner shaft 5 is not easy to rotate relative to the rotating shaft 102, thereby achieving an anti-slip effect.

[0028] As a preferred embodiment of the present invention, a second gasket 9 and a first gasket 8 are provided on the inner shaft 5 ; the second gasket 9 and the first gasket 8 are attached to both sides of the glass door A respectively.

[0029] As a preferred embodiment of the present invention, a decorative cover 4 is provided on the positioning plate 501; a positioning hole is provided on the decorative cover 4; a concave ring 501a is provided on the side wall of the positioning plate 501; a rubber ring 7 is embedded and fixed on the concave ring 501a; after the positioning plate 501 is embedded in the positioning hole, the outer wall of the rubber ring 7 is pressed against the side wall of the positioning hole;

[0030] The decorative cover 4 is used to protect the locking bolts and has a decorative effect; the connection between the decorative cover 4 and the positioning plate 501 is fixed by providing friction through the rubber ring 7, which facilitates the disassembly and assembly of the decorative cover 4 on the positioning plate 501.
