Description

Technical Field

[0001] The present application relates to the technical field of snow transportation vehicles, and in particular to an obstacle-crossing connection structure of a cargo sled slide. Background Art

[0002] A cargo sled is a type of ski vehicle, which is a trailer used to transport goods on the snow. It is widely used in high-altitude and cold areas and is generally composed of a frame and two skis. The front end of the frame is connected to the front vehicle. The two skis under the ski vehicles on the market are structures with both ends raised and the middle part horizontal. The ski vehicles travel on roads with many potholes or snow hills. Due to the large height difference of the road conditions, the height of the two ends of the skis is limited, and they cannot cross roads with too large height differences, which reduces the off-road performance of the ski vehicles and affects the transportation efficiency.

[0003] Therefore, a lot of research has been done in the prior art on how to improve the off-road performance of ski vehicles. For example, the snow trailer disclosed in CN2016100152893 is essentially a ski vehicle, which is connected to the front end of the ski board through the lower end of the tripod, which is conducive to improving the off-road capability of the ski vehicle. However, the defect of the ski vehicle is that the front end of the ski board and the tripod are hinged at an open connection structure without any protective measures, resulting in the obstacle in the process of crossing the obstacle, causing damage to the connection between the two and affecting the service life. Utility Model Content

[0004] The utility model aims to provide an obstacle-crossing connection structure of a cargo sled slide plate in view of the defects and shortcomings of the prior art.

[0007] Preferably, the lower side wall of the ski board has an avoidance groove, the avoidance groove is arranged along the length direction of the ski board, and both ends of the avoidance groove are through-arranged.

[0008] Preferably, the snowboard comprises a skeleton layer and a covering layer, the snowboard is respectively connected to the frame and the connecting rod through the skeleton layer, and the covering layer is coated on the lower side wall of the skeleton layer.

[0009] Preferably, the coating layer extends to both sides of the skeleton layer and covers the edges of both sides of the skeleton layer.

[0010] Preferably, hook strips are respectively provided on both sides of the covering layer, and the covering layer is wrapped around the edges of both sides of the skeleton layer through the hook strips.

[0011] Preferably, the protective baffle is composed of a mounting plate and a blocking plate, the mounting plate is fixed to the side wall of the connecting rod, one end of the blocking plate is arranged at one end of the mounting plate, and the blocking plate is arranged inclined downward from one end close to the mounting plate to the other end.

[0012] Preferably, the frame comprises a pull rod located at the front end of the frame, a sliding sleeve is slidably sleeved on the pull rod, and an end of the connecting rod away from the ski board is hinged to the sliding sleeve.

[0013] Preferably, the snowboard consists of two tilted sections and a supporting section, the two tilted sections are respectively located at two ends of the supporting section, and the inclination of the tilted sections is smaller than the inclination of the connecting rod.

[0014] In summary, the present application includes at least one of the following beneficial technical effects:

[0015] 1. When transporting a ski vehicle, if the height difference is large, the connecting rod connects the front end of the ski board to the frame, and the connecting rod contacts the high part of the road. Then, under the pulling force, the side wall of the connecting rod slides at the high part of the road, allowing the ski board to easily cross the complex road conditions, improving the handling efficiency of the ski vehicle. The protective baffle shields the front end of the ski board, which can resist the objects in front, so that the flying objects will not fall into the upper end surface of the ski board and affect the ski board, thereby improving the stability of the ski board;

[0016] 2. There is an avoidance groove on the lower side of the ski. When encountering a small stone road, the stone will pass through the avoidance groove so that the stone will not lift up the ski, thus providing stability for the ski sled. BRIEF DESCRIPTION OF THE DRAWINGS
