Description

Technical Field

[0001] The utility model relates to the field of vehicle accessories, in particular to a new type of chain with a tightening device. Background Art

[0002] Anti-skid chains are generally made of steel chains or rubber chains and have an anti-skid function. One type is an anti-skid chain that has been connected into a cover shape, and the other type is several separate anti-skid chains installed crosswise. They usually protect car tires on snowy and muddy roads. During the use of the anti-skid chain, the outer surface of the anti-skid chain will rub against the ground, and at the same time, the inside of the anti-skid chain will rub against the outer surface of the car tire, causing the anti-skid chain to loosen after the vehicle has been running for a period of time, resulting in a gap between the anti-skid chain and the surface of the car tire, thereby affecting the protective effect of the anti-skid chain on the car tire. Therefore, an anti-skid chain with adjustable tightness is proposed.

[0003] In response to the above problems, a Chinese patent with publication number CN218558474U discloses an anti-skid chain for automobile tires, including a fixed rod, a movable cavity is opened inside the fixed rod, a fixing groove is opened on one side of the outer surface of the fixed rod, a spring is fixedly connected to the inner wall of the movable cavity, one end of the spring away from the inner wall of the movable cavity is fixedly connected to the movable rod, a toothed edge is arranged on the movable rod, the outer surface of the fixed rod is rotatably connected to a limiting rod, one end of the limiting rod is rotated so that the other end is fixed to between two teeth in the toothed edge through the fixing groove.

[0004] The above scheme adjusts the tightness of the chain cover and the side chain through the adjustment mechanism, so that the chain cover can always fit the surface of the car tire, avoiding the chain cover from loosening and causing accidents when the car tire is driving on special roads. However, its structure is complex and can only be adaptively adjusted through some adjustments.

[0005] Therefore, a new solution is proposed to solve this problem. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a new chain with a tightening device, which can adjust the tensioner and the basket bolt by relative rotation to perform different degrees of adjustment according to different tires, with a large adjustment range and strong tightening force.

[0007] The above technical purpose of the utility model is achieved through the following technical solutions: a new type of chain with a tightening device, comprising a main chain and side chains arranged on both sides of the main chain and connected to the main chain through chain hooks, one of the side chains is provided with an auxiliary locking device, the auxiliary locking device comprises an adjusting tensioner, both ends of the adjusting tensioner are threadedly connected with basket bolts, the end of the basket bolt away from the adjusting tensioner is fixedly connected with a hook, and the hook is movably connected to the side chain.

[0008] By adopting the above technical scheme, the main chain and the side chain are connected by a chain hook, and a chain cover is formed by surrounding the surface of the automobile tire. The auxiliary locking device is arranged on one side of the side chain. When connecting, the hooks arranged at both ends of the adjusting tensioner are respectively connected to the chain hooks connecting the main chain and the side chain to achieve connection. When adjusting, the adjusting tensioner and the basket bolt are relatively rotated to perform different degrees of adjustment according to different tires. The adjustment range is large and the tightening force is strong. It can achieve tightening and loosening on both sides, as well as tightening and loosening on one side.

[0009] The utility model is further configured as follows: the auxiliary locking device is provided with two groups.

[0010] The utility model is further configured as follows: the two groups of auxiliary locking devices are symmetrically arranged.

[0011] The utility model is further configured as follows: one of the side chains adopts a steel wire rope, the outer surface of the steel wire rope is sheathed with plastic coating, a connecting section is formed between the plastic coatings, and the connecting section is connected to the main chain through a double hook.

[0012] By adopting the above technical solution, the steel wire rope is used and plastic coating is provided on the outer side, so that the friction between the side chain and the inner side of the automobile tire can be reduced, thereby extending the service life of the automobile tire.

[0013] The utility model is further configured as follows: the main chain is provided with eight groups.

[0014] By adopting the above technical solution, eight groups of main chains are arranged, which have a large contact area with the car tires and a stronger coverage.

[0015] In summary, the utility model has the following beneficial effects:

[0016] By relatively rotating the adjustment tensioner and the basket bolt, different degrees of adjustment can be performed according to different tires. The adjustment range is large and the tightening force is strong. It can achieve tightening and loosening on both sides or tightening and loosening on one side, and the cost is lower.
