Description

Technical Field

[0001] The utility model relates to the technical field of tracks, in particular to a silent track component. Background Art

[0002] The track assembly can realize the horizontal movement of objects. In order to reduce the noise generated during the use of the track assembly, a silent track assembly is usually selected. Some silent track assemblies include a guide rail and a movable pulley. The bottom wall of the track is provided with a rubber pad, and the movable pulley is provided with a mounting assembly. When in use, the movable pulley is installed in the track, and the lower end of the outer side of the wheel body of the movable pulley contacts the rubber pad, and the left and right ends of the movable pulley contact the top wall of the track through a rectangular seat. During use, the lower end of the outer side of the wheel body of the movable pulley moves along the rubber pad, so that the elasticity of the rubber pad itself can avoid sliding noise during the sliding process between the movable pulley and the track, thereby improving the silent effect of the device. The upper end of the movable pulley contacts the top wall of the track through the rectangular seat, thereby vertically limiting the movable pulley during the sliding process along the track. However, the rubber pad is affected by the external environment and its own service life. After long-term use, the rubber pad itself will shrink and solidify, resulting in a vertical sliding gap between the movable pulley and the track. At this time, due to the lack of effective vertical limiting during the sliding process of the movable pulley along the track, vertical shaking noise is easily generated between the movable pulley and the track, which needs to be improved.

The device can keep the pulley and the track in close contact at all times through an elastic element, avoiding shaking noise between the two due to the curing and shrinkage of the rubber pad, indirectly improving the silent effect of the device itself, and can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a silent track assembly, comprising a guide rail and an anti-swaying and tightening mechanism;

[0005] Guide rail: The guide rail has evenly distributed pulleys slidably connected inside, and a rotating shaft is provided in the middle of each pulley.

The insides of the grooves are fixedly connected to the extrusion seats through evenly distributed telescopic columns. The extrusion seats are installed in cooperation with the guide rails.

[0009] Furthermore, the anti-sway tightening mechanism also includes a spring, which is evenly arranged between the groove and the adjacent extrusion seat. The springs are movably connected to the outer ends of the adjacent telescopic columns. The compression elastic force of the spring ensures that the tightening seat is always in extrusion contact with the top wall of the guide rail.

[0010] Furthermore, the anti-sway and tightening mechanism also includes rotating balls, which are rotatably connected to the semicircular grooves opened on the upper side of the extrusion seat to reduce the sliding resistance between the extrusion seat and the guide rail.
