Description

Technical Field

[0001] The utility model provides a heavy-load shock-absorbing universal wheel, belonging to the technical field of universal wheels. Background Art

[0002] A universal wheel is a wheel that can rotate freely in all directions. It is widely used in furniture, medical equipment, logistics warehousing, industrial equipment and other fields. It allows equipment to be moved flexibly on a flat surface without changing direction. The universal wheel is equipped with bearings inside to ensure smooth and stable rolling. The universal wheel is flexible, stable and adaptable to a variety of surfaces, making it an ideal choice for improving equipment mobility and ease of operation.

[0003] The universal wheels currently used in carts basically have no shock absorption function. When passing through uneven roads, the wheels cannot exert force at the same time, resulting in uneven load bearing. The cart will experience bumps, causing the cargo on the cart to tilt, affecting safety and stability, and the existing wheels have poor load-bearing capacity. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing universal wheels have no shock absorption function and poor bearing capacity.

[0005] In order to solve the above problems, the utility model proposes a technical solution: a heavy-load shock-absorbing universal wheel, including wheels; two wheels are provided, and the two wheels are rotatably arranged on both sides of the rotating shaft, and the two ends of the rotating shaft are rotatably connected to the fixed plate one, the upper end of the fixed plate one is provided with a connecting plate, one side of the fixed plate one is rotatably connected to the fixed plate two, the two fixed plates two are respectively arranged on both sides of one end of the top plate, and damping rods are respectively provided between the two connecting plates and both sides of the other end of the top plate, and the upper end of the top plate is connected to the mounting plate through a bearing.

[0006] As an improvement, the hub of the wheel is made of steel, and the tire is made of a flexible material with high friction;

[0007] As an improvement, the longitudinal section of the fixing plate 1 is L-shaped, and the end portion connected to the fixing plate 2 is arc-shaped;

[0008] As an improvement, the lower end of the second fixing plate is in an arc shape corresponding to the first fixing plate;

[0009] As an improvement, a spring is sleeved on the outside of the damping rod. When the damping rod is in a shortened state, space is left between the upper end of the wheel and the lower end of the top plate.

[0010] Beneficial effects of the utility model:

[0011] By arranging two wheels, the load-bearing capacity of the device is improved, and by arranging a damping rod and a spring, when the device is in use, the wheels can exert force at the same time and achieve a shock-absorbing effect. Description of the Drawings

[0014] The present utility model will be further described below with reference to the drawings.

[0015] According to Figure 1 As shown: The present utility model provides a heavy-duty shock-absorbing universal wheel, which includes a wheel 1; there are two wheels 1, and the two wheels 1 are respectively rotatably arranged on both sides of the rotating shaft 2. The two ends of the rotating shaft 2 are respectively rotatably connected to the first fixing plate 3. A connecting plate 4 is provided at the upper end of the first fixing plate 3. One side of the first fixing plate 3 is rotatably connected to the second fixing plate 5. The two second fixing plates 5 are respectively arranged on both sides of one end of the top plate 6. Damping rods 7 are respectively provided between the two connecting plates 4 and both sides of the other end of the top plate 6. The upper end of the top plate 6 is connected to the mounting plate 9 through a bearing 8; the hub part of the wheel 1 is made of steel material, and the tire part is made of a flexible material with high friction; the longitudinal section of the first fixing plate 3 is L-shaped, and the end of the part connecting the second fixing plate 5 is arc-shaped; the lower end of the second fixing plate 5 is an arc corresponding to the first fixing plate 3; a spring 10 is sleeved outside the damping rod 7. When the damping rod 7 is in a shortened state, there is a space between the upper end of the wheel 1 and the lower end of the top plate 6; by providing two wheels 1, the load-bearing capacity of the device is good. By providing the damping rod 7, when the device is in use, the wheels 1 can be in contact with the ground simultaneously and achieve the shock-absorbing effect.

[0016] Principle of the present utility model: When in use, first install two such devices on both sides of one end of the push handle of a trolley through the mounting plate 9 of the device, and install two fixed wheels at the other end. When placing goods on the trolley, the damping rods 7 and the damping springs 10 will contract, and at the same time, the angle between the first fixing plate 6 and the second fixing plate 5 will change. When the trolley with goods passes through a bumpy road surface, the damping rods 7 and the damping springs 10 will contract again to achieve the shock-absorbing effect, and at the same time, the angle between the first fixing plate 6 and the second fixing plate 5 will change again. Since the device uses two wheels 1, the load-bearing capacity is relatively good.
