Description

Technical Field

[0001] This utility model relates to the field of automotive anti-skid chain technology, and in particular to an adjustable automotive anti-skid chain structure. Background Technology

[0002] In winter, icy and snowy weather reduces road surface friction, making vehicles prone to skidding and seriously affecting driving safety. Snow chains, a commonly used anti-skid device, effectively improve vehicle stability on icy and snowy roads by increasing the friction between the tires and the ground.

[0003] Most existing car snow chains are of fixed size and can only fit specific tire sizes, resulting in poor versatility. Some adjustable snow chains use a simple snap-on adjustment structure, which has low adjustment precision and is prone to loosening due to vehicle vibration after installation, leading to a decrease in anti-skid performance.

[0004] Therefore, an adjustable car anti-skid chain structure that is easy to adjust, highly adaptable, highly stable, and has a good anti-slip effect is proposed. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable car anti-skid chain structure to solve the technical problems of inconvenient adjustment, poor adaptability, insufficient stability and limited anti-skid effect of the existing anti-skid chains.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable automobile anti-skid chain structure, comprising an anti-skid chain body, a fixing component, and a tension adjustment component disposed between the anti-skid chain body and the fixing component. The fixing component includes a connecting frame plate and connecting seats arranged in an array on the outside of the connecting frame plate and fixedly connected to the connecting frame plate. An adjustment cavity is provided in the connecting seat, and the anti-skid chain body is inserted into the adjustment cavity. The tension adjustment component includes a rotating shaft and an adjustment gear rotatably disposed in the adjustment cavity. Connecting belts are fixedly connected to both sides of the anti-skid chain body, and toothed belts that mesh with the adjustment gears are provided on the connecting belts. A locking component is provided on one side of the connecting seat, and the locking component is used to lock the adjustment gears.

[0007] By adopting the above technical solution, during installation, the anti-skid chain body is placed against the tire surface. When the pin and the shaft are not locked, the connecting belt is inserted into the adjustment cavity on the connecting seat. When the anti-skid chain body is in close contact with the tire surface, the shaft is locked by inserting the pin. After the anti-skid chain body has been used for a period of time, the connection between the shaft and the pin is released again. By rotating the shaft, the adjusting gear moves the connecting belt into the adjustment cavity to achieve a tightening effect. After adjustment, the shaft is locked by the pin.

[0008] The present invention is further configured such that: the locking component includes a positioning frame and a pin slidably disposed on the positioning frame, the pin being inserted into a rotating shaft, a spring being sleeved on the pin, a top plate being fixedly connected to the pin, one end of the spring being fixedly connected to the top plate, and the other end of the spring being fixedly connected to the positioning frame.

[0009] By adopting the above technical solution, by pulling down the handle, the handle moves the pin downward, causing the top of the pin to disengage from the through hole on the rotating shaft. Multiple through holes can be set to cooperate with the adjusted rotating shaft and the pin to lock together, thereby releasing the locking relationship between the pin and the rotating shaft. At this time, the user can rotate the rotating shaft to adjust the tension of the anti-skid chain body. After adjustment, by releasing the handle, the pin is locked back to the rotating shaft under the elastic force of the spring.

[0010] The present invention is further configured such that a handle is fixedly connected to the bottom of the pin.

[0011] By adopting the above technical solution, the handle at the bottom of the pin makes it convenient for users to adjust the position of the pin.

[0012] The present invention is further configured such that the anti-skid chain body is provided with 4-8 sets.

[0013] By adopting the above technical solutions, the main body of the anti-skid chain can be customized according to actual use.

[0014] The present invention is further configured such that the anti-skid chain body is provided with a number of gripping nails.

[0015] By adopting the above technical solution, the traction spikes are used to improve the grip friction between the snow chain body and the snow, so as to keep the vehicle moving normally in the snow.

[0016] The present invention is further configured such that: one end of the rotating shaft is provided with a rotating wheel, and limit plates are provided between the rotating shaft and the rotating wheel and at the other end of the rotating shaft extending out of the connecting seat.

[0017] By adopting the above technical solution, the rotation allows the user to rotate the shaft to drive the adjusting gear fixed coaxially with the shaft to rotate. The axial movement of the shaft is constrained by a limiting piece between the shaft and the wheel, as well as at the other end of the wheel extending out of the connecting seat.

[0018] The present invention is further configured such that the other side of the anti-skid chain body is fixedly connected by a chain belt.

[0019] By adopting the above technical solution, when a tension adjustment component is used on one side, the other side of the anti-skid chain assembly is fixed by a chain belt.

[0020] In summary, this utility model has the following beneficial effects:

[0021] The tension adjustment component installed between the snow chain body and the fixing component can be used to adjust the tension between the snow chain body and the connecting seat, thereby improving the fit between the snow chain body and the tire. Attached Figure Description
