Description

Technical Field

[0001] The utility model relates to the field of tire anti-skid chains, in particular to a tire protection chain. Background Art

[0002] Tire protection chains are also called anti-skid chains. Anti-skid chains are an auxiliary tool used to improve vehicle driving stability and safety in adverse weather conditions such as snow, ice or muddy ground. It is usually made of metal, plastic or rubber material and is designed to be fixed on the tire to increase the friction between the tire and the road surface to prevent the vehicle from skidding.

[0003] General anti-skid chains are made of metal chain links connected in an array. Metal anti-skid chains not only have strong ice-breaking ability to prevent vehicles from skidding, but also increase the friction between tires and anti-skid chains to prevent tires from skidding in the anti-skid chains. They are basically the most anti-skid chain of all anti-skid chains. However, the strong anti-skid performance brings about the problem of excessive tire wear, because metal chain links have a relatively high hardness compared to rubber tires. The soft rubber will produce greater wear during use, especially on the thinner tire sidewalls. Greater wear will cause bulges on the tire sidewalls, reducing the service life of the tire. Utility Model Content

[0004] In view of the defects of the prior art, the technical problem to be solved by the utility model is to provide a tire protection chain, by adding a protective cover at the connection of the chain ring, so that the chain ring and the tire sidewall are not in direct contact, thereby preventing the metal chain ring from wearing the tire sidewall and improving the protective effect of the anti-skid chain.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A tire protection chain includes a main chain, a side chain and a steel wire rope, one side of the main chain is connected to the steel wire rope, the other side of the main chain is connected to the side chain, the connecting ends of the main chain, the steel wire rope and the side chain form a connecting part, and also includes a protective sleeve, one end of the protective sleeve is a buffer part, the other end of the protective sleeve is a clamping joint, the clamping joint is installed in the connecting part, and the buffer part is located on the outside of the connecting part.

[0007] Metal chain-link anti-skid chains need to be installed very tightly on the tire. Only in this way can the maximum friction be achieved and the best ice-breaking and anti-skid effect be obtained. However, even if the anti-skid chains are installed in place, the relative position of the anti-skid chains and the tires will still be displaced as they roll. This is an important reason why metal chain-link anti-skid chains wear the tires. The connecting part is where the main chain is connected to the side chain and the wire rope. It is the most prominent point in the entire anti-skid chain and the part with the most severe wear. The connecting part is located on the sidewall of the tire, which aggravates the wear of the tire sidewall. With such a structure, a protective sleeve is installed between the tire and the connecting part, and the connecting part is lifted up so that it does not contact the tire sidewall, thereby preventing the connecting part from wearing the tire sidewall and improving the protective effect of the anti-skid chain.

[0008] Preferably, there are two identical protective sleeves, and the clamping joints of the two protective sleeves are installed in mutual insertion. During the operation of the vehicle, the anti-skid chain is displaced due to the force, and the protective sleeve is also displaced accordingly. If there is a single protective sleeve, there may be a risk of being squeezed and falling off. The design of two protective sleeves plugging into each other reduces the risk of the protective sleeve falling off and improves the protective effect of the protective sleeve.

[0009] Preferably, the clamping joint is cylindrical, and the clamping joint minus two-quarters of the symmetrical part forms a clamping gap, and the other two-quarters of the clamping joint forms a plug-in part, which is clamped in the clamping gap of another protective sleeve, and the plug-in parts are in contact with each other. Such a design increases the force-bearing area between the plug-in parts, reduces the risk of the protective sleeve falling, and further improves the protective effect of the protective sleeve.

[0010] Preferably, the plug-in parts are disconnected to form two plug-in columns, and the plug-in parts are provided with check teeth, which mesh with each other when the plug-in parts are plugged in. The design of the check teeth increases the force bearing area between the plug-in parts, reduces the risk of the protective cover falling, and further improves the protective effect of the protective cover.

[0011] Preferably, the plug-in portion further comprises a reinforcing rib, which is arranged at the root of the plug-in portion and connects the two plug-in posts. When the wheel is starting or stopping, a large force will be applied to the anti-skid chain, which will twist the plug-in posts, causing the check teeth to disengage and causing the protective cover to fall off. The reinforcing rib is connected to the root of the plug-in post, so that the root of the plug-in post will not be twisted, thereby reducing the risk of the protective cover falling off and further improving the protective effect of the protective cover.

[0012] Preferably, the buffer portion includes a mounting surface and an outer protective surface, the clamping joint is arranged at the center of the mounting surface, and the protective surface is a centrally raised arc surface. The arc surface design reduces the wear of the tire sidewall and improves the protective effect of the protective sleeve.

[0013] Preferably, the protective cover is made of acrylonitrile-butadiene-styrene copolymer, which has strong low temperature tolerance, impact resistance and wear resistance, thus increasing the life of the protective cover.

[0014] As a preferred embodiment, a chain hook is also included, one end of which is connected to a side chain or a steel wire rope, and the other end of which is connected to a main chain, and a protective sleeve is installed in the chain hook. The design of the chain hook can replace the main chain that is seriously worn by itself, thereby increasing the service life of peripheral accessories, improving environmental protection, and reducing waste.

[0015] Preferably, a limit strip is provided on the outside of the plug-in column, and the limit strip protrudes from the outside of the plug-in column, so that the protective cover is always located at the best protection point and will not slide up and down in the chain hook, thereby improving the protection effect of the protective cover.

[0016] Preferably, an automatic locker is further included, one end of which is fixedly mounted on the end of the side chain. The automatic locker can make the anti-skid chain fit more tightly on the tire, thereby pressing the protective cover against the tire sidewall, further improving the protective effect of the protective cover.

[0017] In summary, such a tire protection chain adds a protective cover at the connection of the chain ring, so that the chain ring and the tire sidewall are not in direct contact, preventing the metal chain ring from wearing the tire sidewall, greatly improving the protection effect of the anti-skid chain.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] A tire protection chain includes a main chain 1, a side chain 2 and a steel wire rope 3, one side of the main chain 1 is connected to the steel wire rope 3, the other side of the main chain 1 is connected to the side chain 2, the connecting ends of the main chain 1, the steel wire rope 3 and the side chain 2 form a connecting portion 11, and also includes a protective sleeve 4, one end of the protective sleeve 4 is a buffer portion 41, the other end of the protective sleeve 4 is a clamping joint 42, the clamping joint 42 is installed in the connecting portion 11, and the buffer portion 41 is located on the outside of the connecting portion 11.

[0026] Metal chain ring type anti-skid chains need to be installed very tightly on the tire. Only in this way can the maximum friction force be achieved and the best ice-breaking and anti-skid effect be obtained. However, even if the installation is in place, the relative position of the anti-skid chain and the tire will still be displaced as the chain rolls. This is an important reason why metal chain ring type anti-skid chains wear the tire. The connecting part 11 is the part where the main chain 1 is connected to the side chain 2 and the wire rope 3. It is the most prominent point in the entire anti-skid chain and the part with the most severe wear. The connecting part 11 is located on the sidewall of the tire, which aggravates the wear of the sidewall of the tire. With such a structure, a protective cover 4 is installed between the tire and the connecting part 11, and the connecting part 11 is lifted up so that it does not contact the sidewall of the tire, thereby preventing the connecting part 11 from wearing the sidewall of the tire and improving the protective effect of the anti-skid chain.

[0027] Specifically, there are two identical protective sleeves 4, and the clamping joints 42 of the two protective sleeves 4 are inserted into each other. During the operation of the car, the anti-skid chain is displaced due to the force, and the protective sleeve 4 is also displaced accordingly. If there is a single protective sleeve 4, there may be a risk of being squeezed and falling. The design of two protective sleeves 4 inserted into each other reduces the risk of the protective sleeve 4 falling and improves the protective effect of the protective sleeve 4.

[0028] Preferably, the clamping joint 42 is cylindrical, and the clamping joint 42 minus two quarters of the symmetrical part forms a clamping gap 421, and the other two quarters of the clamping joint 42 forms a plug-in portion 422, which is clamped in the clamping gap 421 of another protective sleeve 4, and the plug-in portions 422 are in contact with each other. Such a design increases the force-bearing area between the plug-in portions 422, reduces the risk of the protective sleeve 4 falling, and further improves the protective effect of the protective sleeve 4.

[0029] Furthermore, the plug-in parts 422 are disconnected to form two plug-in columns 423, and the plug-in parts 422 are provided with check teeth 424, which mesh with each other when the plug-in parts 422 are plugged in. The design of the check teeth 424 increases the force-bearing area between the plug-in parts 422, reduces the risk of the protective cover 4 falling, and further improves the protective effect of the protective cover 4.

[0030] Specifically, the plug-in portion 422 further includes a reinforcing rib 425, which is disposed at the root of the plug-in portion 422 and connects the two plug-in posts 423. When the wheel is starting or stopping, a large force is applied to the anti-skid chain, which will twist the plug-in posts 423, causing the check teeth 424 to disengage, resulting in the problem of the protective cover 4 falling off. The reinforcing rib 425 connects the root of the plug-in post 423, so that the root of the plug-in post 423 will not be twisted, thereby reducing the risk of the protective cover 4 falling off, and further improving the protective effect of the protective cover 4.

[0031] Preferably, the buffer portion 41 includes a mounting surface 411 and a protective surface 412. The clamping joint 42 is arranged at the center of the mounting surface 411, and the protective surface 412 is a centrally raised arc surface. The arc surface design reduces the wear of the tire sidewall and improves the protective effect of the protective sleeve 4.

[0032] Preferably, the protective cover 4 is made of acrylonitrile-butadiene-styrene copolymer, which has strong low temperature tolerance, impact resistance and wear resistance, thus increasing the life of the protective cover.

[0033] Preferably, a chain hook 5 is further included, one end of the chain hook 5 is connected to the side chain 2 or the wire rope 3, the other end of the chain hook 5 is connected to the main chain 1, and the protective cover 4 is installed in the chain hook 5. The design of the chain hook 5 can replace the severely worn main chain 1 by itself, thereby increasing the service life of the surrounding accessories, improving environmental protection, and reducing waste.

[0034] Preferably, a limiting strip 426 is provided outside the plug post 423, and the limiting strip 426 protrudes outside the plug post 423. The protective cover 4 is always located at the best protection point and will not slide up and down in the chain hook 5, thereby improving the protection effect of the protective cover 4.

[0035] Preferably, an automatic locker 6 is further included, one end of which is fixedly mounted on the end of the side chain 2. The automatic locker 6 allows the anti-skid chain to be more tightly mounted on the tire, thereby pressing the protective cover 4 against the tire sidewall, further improving the protective effect of the protective cover 4.

[0036] In summary, such a tire protection chain adds a protective cover at the connection of the chain ring, so that the chain ring and the tire sidewall are not in direct contact, preventing the metal chain ring from wearing the tire sidewall, greatly improving the protection effect of the anti-skid chain.

[0037] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
