Description

Technical Field

[0001] This utility model relates to the field of tire cover technology, specifically an anti-slip cover for automobile tires that is easy to adjust tightness. Background Technology

[0002] Tire covers are sheath-like objects placed over the surface of car tires. Their common function is to increase the friction and grip of car tires on slippery roads such as ice, snow, and mud, thereby achieving the purpose of preventing skidding. They are mainly classified into metal snow chains, rubber snow chains, and fabric tire covers. Fabric tire covers are usually made of high-strength fiber fabric, possessing good anti-skid performance and wear resistance. However, after prolonged use, tire covers will wrinkle and loosen due to frequent tire turning. Loosening means a reduced fit between the tire cover and the tire, resulting in a significant decrease in anti-skid effect. Traditional fabric tire covers need to be replaced at this stage. However, the decrease in anti-skid effect at this point is mainly due to loosening; wear on the surface of the tire cover does not completely eliminate its anti-skid ability. Direct replacement makes it difficult to maximize its utilization. Therefore, how to eliminate the decrease in anti-skid effect caused by loosening while the surface of the tire cover still possesses anti-skid capability, and thus achieve maximum utilization of the tire cover, has become an increasingly urgent problem for relevant technicians to solve. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides an anti-slip sleeve for automobile tires that is easy to adjust in tightness.

[0004] An adjustable anti-slip sleeve for automobile tires includes a grounding portion, a transition portion, and a tightening portion. The sleeve is characterized by having two sets of both the transition portion and the tightening portion, with each set symmetrical to the others. The grounding portion, transition portion, and tightening portion are an integral structure. This integral structure has an outer hole at its outer center and an inner hole at its inner center. The outer tightening portion has an outer cavity near the outer hole, with one end open. A binding rope is installed inside the outer cavity, with both ends extending from the opening. The inner tightening portion has an inner cavity near the inner hole, with a rigid band inside the inner cavity.

[0005] Furthermore, the outer tightening part has a first connecting hole arranged in a ring array inside, and a middle ring is provided on the side of the outer cavity near the outer hole. The middle ring has a second connecting hole arranged in a ring array inside, and the second connecting hole is positioned corresponding to the first connecting hole. A connecting band is provided between the second connecting hole and the first connecting hole, and a rope winding hole is arranged in a ring array inside the middle ring.

[0006] Furthermore, hook and loop fasteners are fixedly provided at both ends of the connecting strap, and the hook and loop fasteners at both ends of the connecting strap are glued together.

[0007] Furthermore, a first rigid ring is fixedly provided on the edge of both the first connecting hole and the second connecting hole, and a second rigid ring is fixedly provided on the edge of the rope winding hole.

[0008] Furthermore, the shape of the rope-winding hole is capsule-shaped.

[0009] Furthermore, the grounding part has equidistant parallel protrusions on its surface, and anti-slip textures are provided on its surface.

[0010] The beneficial effects of this utility model of an anti-slip sleeve for automobile tires that facilitates tightness adjustment are as follows:

[0011] 1. If the anti-slip sleeve still provides anti-slip protection but becomes loose, the user only needs to untie the binding rope, realign the anti-slip sleeve, tighten the binding rope, and then thread both ends of the binding rope through the rope loop in a clockwise and counterclockwise direction respectively. When the exposed length of the binding rope ends is appropriate, tighten the binding rope. This will allow the anti-slip sleeve to re-fit against the tire and restore its anti-slip ability before it became loose. This effectively eliminates the decrease in anti-slip effect caused by loosening when the surface of the anti-slip sleeve still has anti-slip ability, thus making the best use of the anti-slip sleeve.

[0012] 2. The rigid band effectively ensures a stable fit between the inner cavity and the inner side of the tire, thereby effectively reducing the loosening of the inner side of the anti-slip sleeve and thus the entire anti-slip sleeve.

[0013] 3. Wear and tear on the anti-slip sleeve will cause the exposed ends of the tie rope to gradually lengthen when tightened. The capsule-shaped design of the rope hole ensures that even if the exposed part of the tie rope becomes longer, there is enough space for it to pass through or even pass through repeatedly. This effectively avoids the unsafe factor that the tie rope may hang on the outside of the tire and get caught in the tire after being pulled out from the outer cavity opening or pulled out of the rope hole once and tied directly.

[0014] 4. The combination of raised parts and anti-slip textures effectively ensures the anti-slip effect of the grounding part and this anti-slip sleeve. Attached Figure Description

Detailed Implementation

[0024] To make the description clearer, the following description of an anti-slip sleeve for automobile tires with adjustable tightness is provided in conjunction with the accompanying drawings.

[0025] An adjustable anti-slip sleeve for automobile tires includes a grounding part 2, a transition part 1, and a tightening part 5. The transition part 1 and the tightening part 5 are each in sets of two, symmetrically arranged. The grounding part 2, transition part 1, and tightening part 5 are an integral structure. This integral structure has an outer hole 4 at its outer center and an inner hole 6 at its inner center. An outer cavity 10 is provided on the side of the outer tightening part 5 near the outer hole 4, with one end open. A binding rope 15 is disposed inside the outer cavity 10, with both ends of the binding rope 15 extending from the opening. An inner cavity 7 is provided on the side of the inner tightening part 5 near the inner hole 6, with a rigid band 8 disposed inside the inner cavity 7.

[0026] Furthermore, the outer tightening part 5 has a first connecting hole 9 arranged in a ring array inside, and a middle ring 11 is provided on the side of the outer cavity 10 near the outer hole 4. The middle ring 11 has a second connecting hole 13 arranged in a ring array inside, and the second connecting hole 13 corresponds to the position of the first connecting hole 9. A connecting strap 14 is provided between the second connecting hole 13 and the first connecting hole 9. The middle ring 11 has a rope winding hole 12 arranged in a ring array inside.

[0027] Furthermore, hook and loop fasteners 18 are fixedly provided at both ends of the connecting strap 14, and the hook and loop fasteners 18 at both ends of the connecting strap 14 are glued together.

[0028] Furthermore, a first rigid ring 16 is fixedly provided on the edge of both the first connecting hole 9 and the second connecting hole 13, and a second rigid ring 17 is fixedly provided on the edge of the rope winding hole 12.

[0029] Furthermore, the rope-winding hole 12 is capsule-shaped.

[0030] Furthermore, the grounding part 2 has equidistant parallel protrusions 3 on its surface, and the grounding part 2 has anti-slip texture.

[0031] The working principle of this utility model of an adjustable anti-slip sleeve for automobile tires is as follows: In the initial state, the anti-slip sleeve is already on the tire surface. The two ends of the binding rope 15 pass through the corresponding rope holes 12 in a clockwise and counterclockwise "outer side-inner side-outer side" cycle, and are tied tightly inside the rope hole 12 at the bottom of the middle ring 11. At this time, the anti-slip sleeve is in contact with the tire, the ground part 2 is in contact with the road surface, and the raised part 3 and the anti-slip texture provide an anti-slip effect. After long-term use, the anti-slip sleeve will wrinkle and loosen due to frequent tire turning. At this time, the user needs to untie the binding rope 15, straighten the anti-slip sleeve, and then tighten the binding rope 15. The two ends of the rope 15 continue to pass through the rope loop 12 on the other side in clockwise and counterclockwise directions as needed. When the exposed length of the rope 15 at both ends is appropriate, tie the rope 15 tightly. This will allow the anti-slip sleeve to re-fit with the tire and restore its anti-slip ability before it loosens. The capsule-shaped rope loop 12 provides sufficient space for the rope 15 to pass through. The first rigid ring 16 maintains sufficient strength for the first connecting hole 9 and the second connecting hole 13, and the second rigid ring 17 maintains sufficient strength for the rope loop 12. It should be noted that the number of rope loops 12 shown in the attached figure is only for display purposes. Manufacturers can increase the number of rope loops 12 and reduce their spacing to prevent the exposed length of the rope 15 from being too short to be tightened.

[0032] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
