[0019] The following description is only used to disclose the utility model so that those skilled in the art can implement the utility model. The embodiments described below are only for example, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not deviate from the spirit and scope of the utility model.

[0020] [Example 1]

[0021] A chain guard structure, such as Figure 1, including a shield body 1, the shield body 1 can be made of plastic or metal material, in this embodiment, it is made of plastic, the shield body 1 is installed with a chain hanging part 7, the chain hanging part 7 is arranged at the tail position of the shield body 1, the chain hanging part 7 is connected to the position adjustment mechanism, the position of the chain hanging part 7 can be adjusted, the chain hanging part 7 is provided with a chain matching part 2 for hanging the chain, the chain matching part 2 and the shield body 1 are on different planes, such as Figure 3 The chain matching part 2 is located inside the shield. When the chain is maintained, the chain 3 can be hung on the chain matching part 2 without contacting the shield body 1.

[0022] Specifically, the chain matching portion 2 is a toothed structure, which is used to insert the chain and match the chain. The toothed structure can be set in one group or in several groups. In this embodiment, several groups of toothed structures are set. Optionally, the toothed structures can be arranged in an inclined linear or arc-shaped manner. Several connecting structures 8 are provided on the shield body 1, and the connection between the shield body 1 and the frame is achieved through the connecting structure 8. In this embodiment, the connecting structure 8 includes two bolt holes, and the connecting structure 8 is arranged at the lower edge of the shield body 1 for easy installation and disassembly. Figure 3 A shielding structure 5 is provided at the upper edge of the shield body 1. The shielding structure 5 is bent inward to form a baffle to improve the protective effect of the shield on the chain. Preferably, a through hole 4 is provided on the shield body 1 to facilitate observation and maintenance of the chain. The through hole 4 has an inwardly protruding edge to strengthen the shield.

[0023] Furthermore, the chain hanging portion 7 is connected to the chain supporting portion 6, and the chain supporting portion 6 plays a supporting role for the chain hanging portion 7 and a guiding role for the chain. In order to adapt to different vehicle models or better meet the needs during maintenance, the chain hanging portion 7 can be set to a movable installation, and a protruding structure 9 is provided on the shield body 1, in which bolt holes are provided, and the thicker material has the effect of strengthening the strength of the connection position, and a circumferential surface is provided outside the protruding structure 9, and a sliding groove is provided on the circumferential surface. The end of the chain supporting portion 6 is installed in the sliding groove, and the height of the chain hanging portion 7 can be adjusted by rotating the chain supporting portion 6, thereby achieving an adjustable effect of the chain hanging position, and then being able to adapt to different vehicle models or better meet the needs during maintenance, as needed It is noted that the sliding groove can also be set at the non-circumferential surface of the protruding position, and the adjustment method of the chain support part 6 can also be linear sliding adjustment. A positioning structure 10 is also provided on the shield body 1, which is used to fix the position of the chain support part 6. The positioning structure 10 and the sliding groove constitute a position adjustment mechanism. The positioning structure 10 is a plurality of strip-shaped ridges arranged on the shield body 1. The width between the upper and lower ridges is equal to the width of the chain support part 6. When the chain support part 6 is moved, the chain support part 6 is deformed, thereby moving between different ridges, and a fixing effect is achieved under the action of the ridges. The ridges can be set to have an arc-shaped outer surface, or can be set to have a trapezoidal cross-section. A hollow can be set in the chain support part 6 to facilitate deformation.
