Description

Technical Field

[0001] This utility model relates to the field of anti-skid chain technology, and in particular to emergency anti-skid chains for trucks. Background Technology

[0002] Vehicle skidding refers to the phenomenon where a vehicle, when traveling on low-traction surfaces such as ice, snow, mud, water, or gravel, experiences a sharp decrease in the coefficient of friction between the tire and the ground, preventing the tire tread from forming sufficient effective grip. This can easily lead to a series of loss-of-control phenomena, such as tire spin, vehicle skidding, and fishtailing. This situation is particularly pronounced in heavy vehicles such as trucks. Due to their large weight and high inertia, once skidding occurs, it is not only difficult to quickly control the vehicle's posture, but it can also lead to collisions with other vehicles, or the vehicle running off the road and overturning, posing a significant threat to the lives of passengers, the safety of the vehicle and its cargo, and even the order of traffic.

[0003] Existing snow chains have poor fastening between the chain and the tire. They are prone to loosening or even shifting due to vehicle vibration or tire deformation. This causes the metal rings to fail to maintain effective contact with the ground, making it difficult to stably exert grip and prevent slipping, thus affecting the reliability of the anti-slip effect. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an emergency anti-skid chain for trucks, which aims to improve the problem of poor fastening between the chain and the tire in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: Truck emergency anti-skid chains include a rectangular plate, a connecting ring connected to the inner wall of the rectangular plate, an iron chain connected to the inner wall of the connecting ring, and a fixing component provided inside the rectangular plate for connecting the other end of the iron chain.

[0006] Preferably, the fixing component includes a threaded rod, the outer wall of which is slidably connected to the inside of the rectangular plate, a nut is threadedly connected to the outer wall of the threaded rod, the bottom end of which is rotatably connected to the upper surface of the rectangular plate, and an iron hook is fixedly connected to the bottom end of the threaded rod, the outer wall of which is connected to the inner wall of the other end of the iron chain.

[0007] Preferably, the lower surface of the rectangular plate is fixedly connected with a corner bracket, which is used to provide fixed support in contact with the car tire.

[0008] This utility model has the following beneficial effects: In this invention, the mutual cooperation between the rectangular plate, connecting ring, iron chain, threaded rod, nut, iron hook and support corner achieves the effect of fastening the iron chain to the tire, solving the problem of poor fastening between the iron chain and the tire, and is conducive to achieving anti-slip by enhancing the grip of the iron chain.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figure 1 An embodiment of this utility model provides an emergency anti-skid chain for trucks, including a rectangular plate 1, a connecting ring 2 connected to the inner wall of the rectangular plate 1, an iron chain 3 connected to the inner wall of the connecting ring 2, and a fixing component provided inside the rectangular plate 1 for connecting the other end of the iron chain 3.

[0013] Specifically, rectangular plate 1 provides a base for the installation and connection of other components, and iron chain 3 is in direct contact with the tire and the ground, using metal material to enhance grip and achieve anti-slip.

[0014] Reference Figure 2 The fixing component includes a threaded rod 4, the outer wall of which is slidably connected to the inside of the rectangular plate 1. A nut 5 is threadedly connected to the outer wall of the threaded rod 4. The bottom end of the nut 5 is rotatably connected to the upper surface of the rectangular plate 1. An iron hook 6 is fixedly connected to the bottom end of the threaded rod 4. The outer wall of the iron hook 6 is connected to the inner wall of the other end of the iron chain 3.

[0015] Specifically, the length is adjusted by the threaded engagement between the threaded rod 4 and the nut 5.

[0016] Reference Figure 3The lower surface of the rectangular plate 1 is fixedly connected with a support corner 7, which is used to provide fixed support in contact with the car tire.

[0017] Specifically, the iron hook 6 hooks the iron chain 3 to secure the anti-skid chain to the tire, which can be adapted to tires of different sizes. The support angle 7 is used to lock onto the tire rim to ensure that the position of the rectangular plate 1 does not move.

[0018] Working principle: Place the rectangular plate 1 on the outside of the tire and use the support angle 7 to clamp it on the tire rim. Pass the iron chain 3 through the inside of the tire and wrap it around the tire once. Pass the iron hook 6 through the inside of the iron chain 3. Rotate the nut 5 to make the threaded rod 4 move upward through the thread. The upward movement of the threaded rod 4 drives the iron hook 6 to move upward. The movement of the iron hook 6 hooks the iron chain 3 tightly, achieving the effect of fastening the iron chain 3 on the tire. This helps to enhance the grip and achieve anti-skid by using the iron chain 3.

[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
