Technical Field
[0001] This utility model relates to the field of tires, and in particular to a tire structure for preventing sideslip of utility vehicles. Background Technology
[0002] Tool carts are indispensable in daily life. They are special vehicles used for storing, transporting, and organizing tools and equipment. They are widely used in industries, maintenance, construction, logistics, and households. To ensure the stability of tool carts during use, they are usually equipped with appropriate anti-skid tires.
[0003] A search revealed a novel anti-slip tire, specifically an anti-slip tire for a handcart, disclosed in Chinese Patent No. CN 221873737 U. This tire includes a tire assembly and a placement assembly. The tire assembly is mounted on the bottom of the placement assembly. The tire assembly includes a mounting frame, inside which rotate several movable wheels. Each movable wheel is a rubber wheel with an anti-slip and wear-resistant layer on its outer wall, and a rubber layer on its outer surface. Each rubber wheel includes a fixed ring with a shock-absorbing layer on its outer surface, and a rubber layer on the outer surface of the shock-absorbing layer. Mounting plates are fixed to both sides of the mounting frame, and mounting holes are opened at the top of the mounting plates. Fixed wheels are located inside the movable wheels, and bearings are fixed inside the fixed wheels. Rotating shafts are fixed inside the bearings, and both ends of the rotating shafts are fixed inside the mounting frame. The fixed wheels include steel rings, and bearings are fixed inside the steel rings. This invention is relatively convenient to use, allows for easy movement of the handcart, has good anti-slip function, and also has shock-resistant properties.
[0004] However, the aforementioned type of anti-skid tire not only significantly increases the cost of use but also increases the weight of the entire vehicle.
[0005] Therefore, it is essential to invent a tire structure for anti-skid on utility vehicles. Utility Model Content

[0007] The annular wide body has the same composition structure as the rubber tire body, and the cross-section between the rubber tire body and the annular wide body is I-shaped.
[0008] An annular cavity is formed between the two sides of the rubber tire body and the corresponding annular wide body.
[0009] An integral reinforcing rib is provided between the outer side of the rubber tire body and the inner side of the annular wide body, and the cross-section of the reinforcing rib is triangular.
[0010] The first anti-slip protrusion structure includes trapezoidal protrusion one, trapezoidal protrusion two, V-shaped protrusion three, and V-shaped protrusion four. The trapezoidal protrusion one, trapezoidal protrusion two, V-shaped protrusion three, and V-shaped protrusion four are evenly disposed on the surface of the rubber tire body.

Grooves are provided between the trapezoidal protrusion one, trapezoidal protrusion two, V-shaped protrusion three, and V-shaped protrusion four.
[0011] The second anti-slip protrusion structure includes a sloping protrusion and a rectangular protrusion. The sloping protrusion and the rectangular protrusion are arranged from the outside to the inside on the surface of the annular wide body. A gap is provided between the sloping protrusion and the rectangular protrusion. The gap is greater than the height of the sloping protrusion and the rectangular protrusion. The sloping surface of the sloping protrusion faces the outside of the annular wide body.

[0022] The present invention will be further described below with reference to the accompanying drawings: Example
[0023] Reference Figure 1-3 A tool vehicle anti-skid tire structure includes a rubber tire body 1, wherein: the rubber tire body 1 is provided with a buffer layer 2 and a tire body ply layer 3 inside, and an integral annular wide body 4 is provided on both sides of the rubber tire body 1. The annular wide body 4 can increase the contact area with the ground. A first anti-skid protrusion structure is provided on the tire surface of the rubber tire body 1, and a second anti-skid protrusion structure is provided on the outer surface of the annular wide body 4. The second anti-skid protrusion structure is flush with the first anti-skid protrusion structure. The first anti-skid protrusion structure and the second anti-skid protrusion structure, together with the annular wide body 4, can increase the contact area with the ground and improve the overall anti-skid capability.
[0024] Specifically, the annular wide body 4 has the same composition structure as the rubber tire body 1. The cross-section between the rubber tire body 1 and the annular wide body 4 is I-shaped. This structure makes the whole structure more stable.
[0025] Specifically, an annular cavity is formed between the two sides of the rubber tire body 1 and the corresponding annular wide body 4. The annular cavity does not affect the disassembly and assembly of the rubber tire body 1. At the same time, the annular wide body 4 can protect the two sides of the rubber tire body 1, reduce the contact between the two sides of the rubber tire body 1 and external objects, and prevent the two sides of the rubber tire body 1 from being punctured, thus making it safer during use.
[0026] Specifically, an integral reinforcing rib 5 is provided between the outer side of the rubber tire body 1 and the inner side of the annular wide body 4. The cross-section of the reinforcing rib 5 is triangular. By providing the reinforcing rib 5, the strength between them can be improved. When impurities enter the annular cavity, friction between the two sides of the rubber tire body 1 can be avoided. At the same time, the impurities can be automatically discharged from the annular cavity during the rolling process of the rubber tire body 1.
[0027] Specifically, the first anti-slip protrusion structure includes trapezoidal protrusion 1 7, trapezoidal protrusion 2 8, V-shaped protrusion 3 9, and V-shaped protrusion 4 10. The trapezoidal protrusion 1 7, trapezoidal protrusion 2 8, V-shaped protrusion 3 9, and V-shaped protrusion 4 10 are evenly arranged on the surface of the rubber tire body 1. The V-shaped protrusion 3 9 and V-shaped protrusion 4 10 are located between the trapezoidal protrusion 1 7 and the trapezoidal protrusion 2 8. The trapezoidal protrusion 1 7 and the trapezoidal protrusion 2 8 face opposite directions, and the V-shaped protrusion 3 9 and the V-shaped protrusion 4 10 face opposite directions. A groove 6 is provided between the trapezoidal protrusion 1 7, the trapezoidal protrusion 2 8, the V-shaped protrusion 3 9, and the V-shaped protrusion 4 10. Through the setting of this structure, water can be drained when it encounters water, and the overall stability can be guaranteed.
[0028] Specifically, the second anti-slip protrusion structure includes a sloping protrusion 11 and two rectangular protrusions 12. The sloping protrusion 11 and the rectangular protrusions 12 are arranged from the outside to the inside on the surface of the annular wide body 4. A gap is provided between the sloping protrusion 11 and the rectangular protrusions 12. The gap is greater than the height of the sloping protrusion 11 and the rectangular protrusions 12. Since the gap is greater than the height of the sloping protrusion 11 and the rectangular protrusions 12, when a side slip occurs, the sloping protrusion 11 and the rectangular protrusions 12 deform. The gap can provide deformation space for the sloping protrusion 11 and the rectangular protrusions 12, further increasing the contact surface with the ground, thereby resisting the side slip. The sloping surface of the sloping protrusion 11 faces the outside of the annular wide body 4.
[0029] Specifically, grooves 13 are provided on the outward-facing sides of the inclined protrusion 11 and the rectangular protrusion 12. By providing grooves 13, when the inclined protrusion 11 and the rectangular protrusion 12 deform to one side, the friction between the inclined protrusion 11 and the rectangular protrusion 12 and the ground can be increased, thereby further resisting side slippage.
[0030] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
