Abstract
Description
Technical Field
[0001] The utility model mainly relates to a bouncing guide wheel.
Background Art
[0002] Traditional sliding doors generally have pulleys installed at the bottom to change the sliding friction into rolling friction through the pulleys when the sliding doors slide, so as to reduce the resistance when the sliding doors move. However, the traditional pulleys need to be used in cooperation with the tracks, and at the same time, the pulleys will generate friction with the tracks, resulting in noise. In view of this, we propose a bouncing guide wheel structure to replace the movement of the traditional pulleys, which is more convenient to use.

[0005] The pulley seat has a cavity, and the guide wheel is hinged in the cavity; the torsion spring is installed in the cavity, and both ends of the torsion spring respectively abut against the guide wheel and the pulley seat. The pulley seat is provided with an opening, and the opening is communicated with the cavity so that the pulley set extends out of the pulley seat from the opening under the push of the torsion spring;
[0006] The pulley seat is provided with a slot, and the extension assembly is inserted into the slot, and the extension assembly moves in the slot to adjust the length of the extension assembly extending out of the pulley seat.

[0013] The beneficial effects of the present utility model compared with the background technology:
[0014] The present utility model provides a bouncing guide wheel. When in use, the bouncing guide wheel is installed on a sliding door. When the sliding door slides on the track, the torsion spring of the bouncing guide wheel can absorb the impact caused by uneven ground or track deformation, reduce vibration, and make the operation of the sliding door smoother. In addition, the bouncing guide wheel can also reduce noise. When the sliding door slides, the traditional pulley may rub against the track and generate noise. However, due to its special design, the bouncing guide wheel can cancel the track connection and directly contact the ground, which can reduce this friction and thus reduce noise. It has the advantages of simple structure, compact cooperation, and reasonable design; therefore, it is a product with excellent technical and economic performance.

The pulley seat 1 is provided with an opening 12, and the opening 12 communicates with the cavity 11 so that the pulley set extends out of the pulley seat 1 from the opening 12 under the push of the torsion spring 3;
[0023] The pulley seat 1 is provided with a slot 13, the extension assembly 4 is inserted into the slot 13, and the extension assembly 4 moves in the slot 13 to adjust the length of the extension assembly 4 extending out of the pulley seat 1.

The guide wheel 2 is hinged in the cavity 11 through the wheel frame 5. The wheel frame 5 is an integral structure. The wheel frame 5 includes a top part 51 and side parts 52. The side parts 52 are connected to both sides of the top part 51, and the side parts 52 are perpendicular to the top part 51. One end of the torsion spring 3 abuts against the pulley seat 1, and the other end abuts against the top part 51. The length of the top part 51 is less than the length of the side parts 52 to reserve space for the wheel body 6 to extend out of the wheel frame 5 to facilitate the rotation of the wheel body 6. The side parts 52 are provided with a shaft hole 53 and a guide groove 54. The guide groove 54 is arc-shaped to cooperate with the rotation of the guide wheel. The shaft hole 53 is used for connecting the wheel body 6 and the pin shaft 21. A cross bar 14 is installed in the cavity 11, and the cross bar 14 is connected to the guide groove 54 to control the movement track of the guide wheel 2 through the cooperation of the cross bar 14 and the guide groove 54.
[0025] The extension component 4 includes an extension bar 7, a first follower guide wheel 8, and a second follower guide wheel 9. The extension component 4 is connected to the slot 13 through the extension bar 7 to be installed on the pulley seat 1.
