Description

Technical Field

[0001] This utility model belongs to the field of anti-skid chain technology, specifically an anti-skid chain. Background Technology

[0002] When vehicles travel in winter, especially in icy and snowy climates in northern regions, the friction between the tires and the ground is greatly reduced due to the presence of ice or snow, making it easy for the wheels to slip and cause accidents. To avoid such accidents, many vehicles are equipped with snow chains to increase the friction between the tires and the ground, thus increasing the safety factor of the vehicle. Existing snow chains have a simple structure, adjusting the size of the snow chain by adding or removing standard chain links to make it grip the tire. However, this adjustment method is not convenient enough. First, the disassembly and assembly of the chain is not simple; second, the removed chain is easy to lose; and more importantly, the adjustment precision is not high, making it difficult to ensure that the adjusted snow chain is accurately adapted to the tire size, thus affecting the stability of the snow chain and reducing its effectiveness. Therefore, it is necessary to develop a new type of snow chain to overcome the shortcomings of existing technology. Utility Model Content

[0032] Working principle and usage process of this utility model:

[0033] As shown in the figure, the first connecting ring 2 and the adjusting soft steel wire 3 are assembled to form the adjusting lock 4. For example... Figure 1 Two adjusting soft steel wires 3 and adjusting lock 4 are connected to the left and right sides of the anti-skid chain body 1 through the first connecting ring 2. After the anti-skid chain body 1 is wrapped around the tire, the two ends of the adjusting soft steel wires 3 are respectively inserted into the upper and lower through holes 43 on the front and rear sides of the adjusting lock 4.

[0034] Specifically, one end of the adjusting soft steel wire 3 is inserted into the through hole 43 at the front end of one of the locking units 411, passes through, then wraps downward and inserts into the through hole 43 at the front end of another locking unit 411; then the other end of the adjusting soft steel wire 3 is inserted into the through hole 43 at the rear end of one of the locking units 411, passes through, then wraps downward and inserts into the through hole 43 at the rear end of another locking unit 411, and the adjusting soft steel wire 3 is tightened and, with the cooperation of several first connecting rings 2, the anti-skid chain body 1 is firmly wrapped around the tire surface;

[0035] Then, by turning the dial 449, the adjusting screw 442 can be rotated under the constraint of the connecting shaft 448 and the positioning shaft 447. Then, under the constraint of the sliding groove 413, the adjusting screw 442, with the cooperation of the support rod 443, the first connecting frame 445 and the second connecting frame 446, pushes the two locking teeth 441 away from each other through the sliding sleeve 444, and presses the two ends of the adjusting soft steel wire 3 under the constraint of the through hole 43.
