[0024] Please refer to Figures 1 to 2 As shown, it shows the specific structure of the preferred embodiment of the present invention, which is fixedly connected to the motorcycle and is covered on the outside of the motorcycle rear wheel chain in a semi-wrapped form. It is stamped from a metal sheet and includes a top cover plate 10.

[0025] The top cover plate 10 is arranged horizontally, and an avoidance groove 11 is opened on the outer side of the middle part of the top cover plate 10. In this embodiment, the top cover plate 10 is in the shape of a long straight plate, which covers the upper part of the rear wheel chain of the motorcycle. The structure is simple, and the avoidance groove 11 is in an arc shape, which has a beautiful appearance and a sporty style.

[0026] The front outer side of the top cover plate 10 is bent downward to form a front cover plate 20, and the inner and outer side surfaces of the front cover plate 20 are penetrated by a front fixing hole 21. In this embodiment, the front cover plate 20 is bent vertically at 90 degrees relative to the top cover plate 10. The front cover plate 20 is a quadrilateral flat plate structure, and the inner and outer side surfaces of the front cover plate 20 are penetrated by a plurality of hollow holes 22 to achieve weight reduction. At the same time, the rear wheel chain of the motorcycle can be observed through the hollow holes 22. In addition, the plurality of hollow holes 22 are arranged in parallel with each other at intervals in front and back. Each hollow hole 22 is a long hole extending obliquely up and down, with an aesthetically pleasing appearance and a sporty style. In addition, the front fixing hole 21 is a round hole, and the front fixing hole 21 is close to the lower side of the front end of the front cover plate 20, so that it can be fixed to the motorcycle by screws passing through the front fixing hole 21.

[0027] The rear end of the top cover 10 is bent downwardly to form a rear cover 30. Rear fixing holes 31 are defined on the inner and outer sides of the rear cover 30. The rear cover 30 is separated from the front cover 20 and, together with the clearance groove 11, forms a clearance space 101 for the motorcycle's rear fork. In this embodiment, the rear cover 30 is bent perpendicularly at a 90-degree angle relative to the top cover 10. It is a trapezoidal flat plate with a shorter bottom than top. Arc-shaped clearance holes 32 are defined on the inner and outer sides of the rear cover 30, positioned above the rear fixing holes 31 to clear motorcycle components. Furthermore, the rear fixing holes 31 are circular and located near the center of the underside of the front cover 30, allowing screws to secure the rear fork to the motorcycle.

[0028] The method of using this embodiment is described in detail as follows:

[0029] When in use, this product is half-wrapped and placed on the outside of the motorcycle's rear wheel chain. Then, two screws are respectively passed through the front fixing hole 21 and the rear fixing hole 31 to fix it to the motorcycle. At this time, the top cover plate 10 covers the top of the motorcycle's rear wheel chain, and the front cover plate 20 and the rear cover plate 30 cover the outside of the motorcycle's rear wheel chain to provide good protection for the motorcycle's rear wheel chain.

[0030] The design focus of the utility model is: this product is stamped from metal plates, has good structural strength, is not easy to damage, can protect the chain very well, and this product is semi-wrapped and covered on the outside of the motorcycle rear wheel chain, which is convenient for daily maintenance of the chain. At the same time, by setting front fixing holes and rear fixing holes, only two screws are needed to install and fix this product on the motorcycle. The installation is simple and firm, and will not affect the use of the vehicle after installation, which brings convenience to use.

[0031] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
