[0022] The following further describes in detail the embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0023] In the description of the present utility model, unless otherwise specified, the meaning of "a plurality of" is two or more; the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, terms such as "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0024] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] Please refer to Figures 1-5 , an anti-slip chain for a tire 3 that is easy to fix, including a tire 3, a fixing block 5, a tension chain 1 arranged on the tire 3, and a plurality of side anti-slip chains 2. A first tension belt 17 and a second tension belt 18 are connected to the fixing block 5. The first tension belt 17 and the second tension belt 18 are respectively connected to both ends of the tension chain 1. A cavity 8 is formed in the fixing block 5. A rotating column 11 is rotatably installed in the cavity 8. One end of the first tension belt 17 away from the tension chain 1 is connected to the rotating column 11. A plurality of teeth 12 are evenly arranged along the circumferential direction on one side of the rotating column 11. A plurality of tooth grooves 13 adapted to the teeth 12 are evenly formed along the circumferential direction on one inner wall of the cavity 8. A sliding groove 15 is formed on the inner wall of the cavity 8 away from the tooth grooves 13. The sliding groove 15 is adapted to the size of the rotating column 11. A compression spring 10 is arranged in the sliding groove 15. One end of the compression spring 10 is installed on the inner wall of the sliding groove 15, and the other end of the compression spring 10 is installed on the rotating column 11.

[0026] Through the arrangement of the tooth grooves 13 on the inner wall of the cavity 8 in the fixed block 5, the engaging teeth 12 on the rotating column 11, and the compression spring 10, the one-way self-locking function of the rotating column 11 can be ensured, so that the rotating column 11 can only rotate in one direction. When it is necessary to tighten the tension chain 1, the rotating column 11 can be rotated to wind the first tension belt 17 around the rotating column 11. When it is necessary to unlock the rotating column 11, only move the rotating column 11 in the direction of the sliding groove 15 to separate the engaging teeth 12 from the tooth grooves 13, thereby releasing the locking of the rotating column 11, and then the unwinding of the first tension belt 17 can be realized, ensuring that the tension chain 1 remains stable during driving, so that the tension chain 1 can adapt to tires 3 of different sizes and different road surfaces.

[0027] Specifically, in this embodiment, one end of the second tension belt 18 far from the tension chain 1 is installed on the fixed block 5.

[0028] Specifically, in this embodiment, a rotating shaft 16 is installed at one end of the rotating column 11 far from the engaging teeth 12, and a rotating hole 14 adapted to the rotating shaft 16 is formed on the inner wall of the cavity 8. Through the rotating shaft 16 and the rotating hole 14, the rotating column 11 can rotate in the rotating hole 14 through the rotating shaft 16, achieving the purpose of restricting the position of the rotating column 11.

[0029] Specifically, in this embodiment, a knob 7 is installed at one end of the rotating shaft 16 far from the rotating column 11. Through the setting of the knob 7, it is convenient to adjust the rotating column 11.

[0030] Specifically, in this embodiment, a plurality of anti-slip grooves are spaced apart along the circumferential direction on the outer surface of the knob 7.

[0031] Specifically, in this embodiment, a through hole 9 communicating with the cavity 8 is formed on the fixed block 5, and the first tension belt 17 passes through the through hole 9 and is connected to the tension chain 1.

[0032] Specifically, in this embodiment, a plurality of side anti-slip chains 2 are connected to the tension chain 1 through connecting buckles 4.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
