Technical Field

[0001] The invention relates to the field of anti-skid chains, in particular to an anti-skid chain for automobile tires. Background Art

[0002] In adverse weather conditions, such as snowy weather or muddy roads, the friction between car tires and the ground is significantly reduced, which can easily cause the vehicle to slip and lose control, leading to traffic accidents. At present, common anti-skid measures include anti-skid chains and anti-skid tires. Although anti-skid chains have a good anti-skid effect, the installation process is complicated and requires professional tools and certain operating skills, and it is easy to cause damage to the tires and the road surface during driving; anti-skid tires are relatively expensive, and under extreme conditions, their anti-skid performance also has certain limitations. In addition, some existing simple anti-skid cloth covers need to be designed to almost completely fit the tire in order to maintain tightness with the tire, so it is more laborious to install the anti-skid cloth covers.

[0003] Therefore, it is necessary to invent a kind of automobile tire anti-skid chain to solve the above problems. Summary of the invention

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0020] The present invention provides an anti-slip chain for an automobile tire as shown in Figure 1-7 Figure 14, which includes an anti-slip cloth sleeve 1. The anti-slip cloth sleeve 1 is a ring-shaped structure with openings in the middle of the front and rear sides. Tensioning belts 2 are sewn at the openings on the front and rear sides of the anti-slip cloth sleeve 1. Since the anti-slip cloth sleeve 1 is a ring-shaped structure, the tensioning belts 2 are also ring-shaped structures. Main friction belts 3 are sewn around the anti-slip cloth sleeve 1. A group of auxiliary friction belts 4 are arranged on the side walls of the plurality of main friction belts 3. The auxiliary friction belts 4 are also sewn to the anti-slip cloth sleeve 1. Each group of auxiliary friction belts 4 has six. Slave connecting lines 5 are fixedly connected to the front and rear inner side walls of the six auxiliary friction belts 4. The plurality of slave connecting lines 5 are commonly connected to a main connecting line 6. The main connecting line 6 and the slave connecting lines 5 are made of wires with a certain tensile strength and toughness, such as Kevlar ropes, Dyneema ropes, and steel wires, etc. One end of the plurality of main connecting lines 6 is commonly connected to a rotating buckle 7. One main connecting line 6 is connected to a total of twelve slave connecting lines 5, namely six slave connecting lines 5 connected to the front side of each group of auxiliary friction belts 4 and six slave connecting lines 5 connected to the rear side of each group of auxiliary friction belts 4. By simultaneously pulling the slave connecting lines 5 on the front and rear sides of each group of auxiliary friction belts 4, it is more convenient and stable to make each group of auxiliary friction belts 4 contract

[0021] As shown in Figure 2 and Figure 3As shown in the figure, annular cloth bags 8 are sewn on both the front and back sides of the anti-slip cloth cover 1. The two annular cloth bags 8 correspond to the central positions of the auxiliary friction belts 4. U-shaped cloth bags 9 are sewn on the inner walls around the anti-slip cloth cover 1. The U-shaped cloth bags 9 correspond to the inner sides of the main friction belts 3. The U-shaped cloth bags 9 are interconnected with the annular cloth bags 8. The main connecting lines 6 are located inside the U-shaped cloth bags 9, and the slave connecting lines 5 are located inside the annular cloth bags 8. By hiding the main connecting lines 6 and the slave connecting lines 5, the problem that the tires directly cause wear to the main connecting lines 6 and the slave connecting lines 5 can be avoided.

[0022] As Figure 4 As shown in the figure, the rotating buckle 7 further includes a housing 71. Elastic pieces 72 are fixedly connected to the inner walls around the housing 71. A rotating disk 73 is further arranged inside the housing 71. Ratchet teeth 74 are fixedly connected to the four sides of the rotating disk 73. The ratchet teeth 74 and the rotating disk 73 are integrally formed. A winding post 75 is fixedly connected to the front side of the rotating disk 73. Multiple main connecting lines 6 are fixedly connected to the winding post 75. The multiple main connecting lines 6 are arranged in a staggered manner. Inlet holes corresponding to the main connecting lines 6 are formed in the four sides of the housing 71. A rotating block 76 is fixedly connected to the front side of the winding post 75. By rotating the rotating block 76, the rotating block 76 drives the winding post 75 to rotate, and the winding post 75 winds up the main connecting lines 6. During the winding process, the ratchet teeth 74 around the rotating disk 73 press against the elastic pieces 72. Since the elastic pieces 72 are inclined, the elastic pieces 72 will deform when the ratchet teeth 74 pass by. However, when the ratchet teeth 74 reverse, the inclined elastic pieces 72 will block the ratchet teeth 74. Therefore, the winding post 75 can be used to wind up the main connecting lines 6, and the main connecting lines 6 will not unwind.

[0023] As Figure 7 As shown in the figure, a threaded hole is formed in the rear side of the rotating disk 73, and a bolt 10 is threadedly connected to the threaded hole. There is a gap between the bolt 10 and the housing 71, so there will be no mutual friction with the housing 71. When it is necessary to unwind the main connecting lines 6, rotate the bolt 10 to increase the gap between the bolt 10 and the housing 71, and pull the bolt 10 to the position when it is not rotated. At this time, the ratchet teeth 74 on the rotating disk 73 are separated from the elastic pieces 72. A through hole corresponding to the bolt 10 is formed in the rear side of the housing 71. If it is necessary to unwind the main connecting lines 6, rotate the bolt 10 to make the bolt 10 away from the housing 71, and pull the rotating block 76, thereby pulling the rotating disk 73, so that the ratchet teeth 74 on the rotating disk 73 are disengaged from the elastic pieces 72. At this time, the entire anti-slip cloth cover 1 can be manually restored. After the restoration is completed, insert the rotating disk 73 again and rotate the bolt 10 so that the rotating disk 73 cannot be pulled out. At this time, there is still a gap between the bolt 10 and the housing 71, so the problem of difficult rotation of the winding post 75 will not occur.

[0024] As Figure 1As shown in the figure, multiple sets of creases 11 are provided on the outer side of the anti-slip cloth sleeve 1. Each set of creases 11 consists of two creases. Each set of creases 11 is located between two adjacent secondary friction belts 4. Since the creases 11 are provided on the anti-slip cloth sleeve 1, when the secondary friction belt 4 is pulled, the anti-slip cloth sleeve 1 can be contracted along the creases 11, making the contraction of the anti-slip cloth sleeve 1 more orderly. The stacked anti-slip cloth sleeves 1 formed by the contraction can also increase the friction of the anti-slip cloth sleeve 1, achieving a better anti-slip effect.

[0025] As Figure 1 and Figure 3 shown in the figure, connecting bands 12 are fixedly connected to the periphery of the rotary buckle 7. The connecting bands 12 are sewn to the anti-slip cloth sleeve 1. Through the multiple connecting bands 12 provided, the rotary buckle 7 can be lifted by the connecting bands 12, thereby limiting the position of the rotary buckle 7 and preventing the rotary buckle 7 from directly contacting the tire.

[0026] The working principle of the present invention: The anti-slip cloth sleeve 1 is sleeved on the surface of the tire through the tensioning belt 2 provided. By rotating the rotating block 76, the rotating block 76 drives the winding column 75 to rotate. The winding column 75 winds up the main connecting line 6. During the winding process, the ratchet teeth 74 around the rotating disk 73 squeeze the elastic piece 72. Since the elastic piece 72 is inclined, the elastic piece 72 will deform when the ratchet teeth 74 pass by. However, when the ratchet teeth 74 reverse, the inclined elastic piece 72 will block the ratchet teeth 74. The four main connecting lines 6 can simultaneously pull the secondary connecting lines 5 on the front and rear sides of the secondary friction belt 4 during the winding process, so that multiple secondary friction belts 4 contract synchronously. Since the creases 11 are provided on the anti-slip cloth sleeve 1, when the secondary friction belt 4 is pulled, the anti-slip cloth sleeve 1 can be contracted along the creases 11, making the contraction of the anti-slip cloth sleeve 1 more orderly. The stacked anti-slip cloth sleeves 1 formed by the contraction can also increase the friction of the anti-slip cloth sleeve 1, achieving a better anti-slip effect.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
