Description

Technical Field

[0001] The utility model belongs to the technical field of cargo sleds, and in particular relates to a slide plate mounting structure of a cargo sled. Background Art

[0002] Ordinary motorcycles and ordinary vehicles are difficult to drive normally on the snow, so there are special snowmobiles and snowmobiles on the snow. When goods or wounded people need to be transported on the snow, a ski vehicle for transporting goods or wounded people is usually installed on the rear of the snowmobile or snowmobile. The cargo sled is a type of ski vehicle. Usually, skis are installed at the bottom of the ski vehicle for driving. However, under road conditions with many potholes, snow hills, and obstacles, traditional snow trailers have poor shock absorption ability, low stability, and poor riding comfort during driving.

[0003] After searching, the Chinese invention patent (application publication number: CN105539562A) provides a trailer, including a frame and two skis installed at the bottom of the frame, the frame including a support frame, a cargo rack and a traction frame; the support frame includes a support shaft and a combination slide foot of a herringbone structure installed at both ends of the support shaft; the lower end of each of the combination slide feet is connected to a ski board; the cargo rack is a frame structure, and the middle part of the cargo rack is rotatably connected to the support shaft; the rear end of the traction frame is connected to the support shaft, and the middle part of the traction frame is connected to the cargo rack; the ski board is a split ski board, which includes a plastic plate body and a front iron slide board and a rear iron slide board fixed at both ends of the plastic plate body; the combination slide foot is provided with a front supporting foot hinged to the front iron plate and a rear supporting foot slidably connected to the rear iron plate.

[0004] A buffer rod hinged to the tripod is installed at the front of the traction frame; the buffer rod includes a guide rod arranged along the length direction of the traction frame, two springs sleeved on the guide rod, and a slider sleeved on the guide rod and located between the two springs; the tripod is hinged to the slider through a connecting piece.

[0005] The snowboard adopts a split structure design, with a plastic plate as the main body. Metal plates are installed at the front and rear ends of the plastic plate, namely the front iron plate and the rear iron plate. When passing through low-lying or snow hill roads, the middle part of the plastic plate is sunken or bulged, which plays a role in buffering and shock absorption. It should be emphasized that the combined ski foot is connected to the front iron plate and the rear iron plate through the front supporting foot and the rear supporting foot respectively. Among them, the front supporting foot adopts a rotatable connection to the front iron plate, and the rear supporting foot adopts a sliding connection to the rear iron plate. When the plastic plate bends due to changes in road conditions, the round tube on the rear supporting foot will slide back and forth on the rear support to eliminate the impact force on the combined ski foot. Avoid deformation of the frame after impact and reduce bumps.

[0006] The above-mentioned invention patent has a plastic plate body in the middle of the ski board that can play a buffering role when encountering a dirt hill or a snow hill, and a relative slip can occur between the combined ski feet and the rear iron plate, further reducing the impact on the frame; in addition, the cargo rack and the traction rack rotate around the support axis, and have a good shock-absorbing and buffering effect when passing through a road with many potholes and snow hills, so the driving is smooth and the ride is highly comfortable.

[0007] It can be learned from the above-mentioned prior art that when the existing snow trailer is in the moving direction, the round tube on the rear supporting foot will slide back and forth on the rear supporting member to eliminate the impact force on the combined sliding foot, avoid deformation of the frame after impact, and reduce bumps. However, if the weight of the goods carried on the rack is uneven, causing the center of gravity of the goods to be backward, the rear supporting foot will slide backward, causing the rack to tilt, thereby making the connection strength between the rack and the ski board insufficient, and also making the overall structure of the trailer unstable. Therefore, this shortcoming needs to be improved urgently. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 6 As shown, a skateboard mounting structure of a cargo sled includes a frame 1 and a ski 2 mounted on the bottom of the frame 1. In the present application, there are two skis 2, and a connecting seat 23 is provided in the middle of the ski 2. The frame 1 includes a support frame 12 hingedly mounted on the connecting seat 23. A traction rod 11 is provided at the front end of the frame 1, and a buffer assembly 3 is provided between the traction rod 11 and the ski 2. The buffer assembly 3 includes a movable block 31 slidably mounted on the traction rod 11. In the present application, the movable block 31 is sleeved on the outer periphery of the traction rod 11, and the lower end of the movable block 31 is movably connected to the buffer frame 33. The ski 2 is hinged to the other end of the buffer frame 33 and is directly hingedly mounted on the connecting seat 23 through the support frame 12, so that the frame will not be tilted during movement, thereby making the ski vehicle structure more stable.

[0029] Preferably, a connecting plate 32 may be further provided at the lower end of the movable block 31 , and the buffer frame 33 is hingedly connected to the connecting plate 32 , so as to facilitate installation.

[0030] The frame also includes a connecting frame 13, which is connected between the support frame 12 and the traction rod 11. One end of the connecting frame 13 is connected to the support frame 12. In the present application, the connecting frame 13 and the support frame 12 are connected by welding, so the connection strength between the connecting frame 13 and the support frame 12 can be greatly improved. In addition to the welding connection, the connecting frame 13 and the support frame 12 can also be connected by bolts and nuts or snap-on connection, and the other end of the connecting frame 13 is provided with a sleeve 14, which is sleeved on the outer periphery of the traction rod 11, and a sleeve 14 is installed between the sleeve 14 and the traction rod 11. The connecting shaft 15 and the sleeve 14 swing around the axis of the connecting shaft 15. The sleeve 14 has a through cavity 141. There is a gap between the traction rod 11 and the through cavity 141 for the traction rod 11 and the sleeve 14 to swing relative to each other. Therefore, when the sleeve 14 swings, the gap between the through cavity 141 in the sleeve 14 and the traction rod 11 can allow the traction rod 11 and the sleeve 14 to swing relative to each other, and the upper and lower end walls of the through cavity 141 can limit the maximum angle of relative swing between the sleeve 14 and the traction rod 11, thereby preventing the sleeve 14 and the traction rod 11 from swinging too much and causing damage.

[0031] A protective plate 34 is installed on the buffer frame 33 to prevent obstacles from falling onto the top of the ski 2. The protective plate 34 is set at an angle to the lower end of the buffer frame 33, and when the ski 2 is in a horizontal state, the bottom height of the end of the ski 2 close to the buffer frame 33 is higher than the lower height of the protective plate 34. Therefore, the protective plate 34 can better block debris and obstacles such as stones and branches, prevent debris and obstacles from falling onto the top of the ski 2, and prevent obstacles from directly colliding with the hinge point between the ski 2 and the buffer frame 33, thereby causing damage and breakage of the hinge point. In addition, the ski cover is provided with a rubber pad 25, which protects the ski 2.

[0032] The upper end of the ski board 2 has a reinforcing plate 21 connected to the support frame 12. The strength of the connection can be improved by connecting the reinforcing plate 21 to the support frame 12. The lower end of the ski board 2 is provided with a clearance groove 22 for allowing obstacles to pass through, and the top of the ski board 2 is provided with grooves 24 symmetrically arranged on both sides of the clearance groove 22, thereby reducing the contact area between the ski board 2 and the ground.

[0033] Furthermore, the front and rear ends of the snowboard 2 both have a raised portion 211 , and the raised portion 211 of the snowboard 2 can reduce the impact when the snowboard 2 collides with an obstacle.

[0034] When in use: by putting the connecting ring 421 on the towing hook of the snowmobile or snowmobile, when the snowmobile or snowmobile is moving forward, the snowmobile passes through a low-lying, snowy hillock or a road section with many obstacles, when the snowboard 2 touches an obstacle, such as a snow hillock, the front end of the snowboard 2 will swing upward, and since the buffer frame 33 is hinged to the snowboard 2, the buffer frame 33 also moves at the same time, and the movable block 31 slides on the traction rod 11, so that buffering and shock absorption in the moving direction can be achieved, and through the hinge between the connecting plate 32 and the buffer frame 33, the buffer frame 33 and the ski The hinges between the snowboards 2, between the snowboards 2 and the support frames 12, and between the sleeves 14 on the connecting frame 13 and the traction rod 11, make the snowboards 2 become flexible collisions when they hit obstacles. Therefore, through the cooperation of various hinge points, it is possible to reduce the vibration perpendicular to the moving direction, so that the goods placed on the ski vehicle can be transported more stably or the injured lying on the ski vehicle can lie more comfortably. In addition, the support frame 12 is directly hingedly installed on the connecting seat 23, so that the frame will not tilt during movement, thereby making the ski vehicle structure more stable.
