Description

Technical Field

[0001] The utility model relates to a bracket for a ski machine. Background Art

[0002] With the development of the skiing industry, more and more people are participating in skiing; however, since skiing is greatly affected by the seasons and the outdoor skiing season is short each year, indoor skiing has attracted people's attention. The ski machine includes a bracket, a snow blanket, a motor and other structures. The upper and lower ends of the snow blanket are mounted on rollers and fixed on the bracket. The motor drives the rollers to rotate and drive the snow blanket to roll upward. The snow blanket simulates the texture of the snow in a real ski resort. Skiers slide on the rolling snow blanket, thereby simulating the movement of skiing in a real ski resort; the ski machine can also simulate the speed of the skier and the slope of the ski resort by adjusting the speed or slope of the snow blanket.

[0003] The brackets of existing ski machines are usually welded from square tubes or I-beams, which are welded on site at the venue according to the design drawings or welded in the processing plant before being transported to the venue as a whole. Therefore, the brackets of existing ski machines are integrated fixed structures, which are inconvenient to install and disassemble, and are large in size and difficult to transport. In addition, the rollers of the snow blankets on existing ski machines are connected to bearings at both ends, and the bearings are welded on the brackets and cannot be moved. With the long-term use of the ski machine, the snow blanket will become loose, which seriously affects the skiing experience. To tighten it again, the bearings need to be completely disassembled and re-welded, which is difficult to operate and highly destructive, affecting the integrity and safety of the equipment.
