[0002] A bicycle fender is a component installed near the bicycle wheel, mainly used to prevent mud and water from splashing onto the rider's legs, and also has the function of protecting the bicycle and other components from dirt and corrosion. Bicycle fenders are usually made of plastic, rubber or metal, which are light and durable and can effectively block mud and water.
[0003] According to different bicycle models, the rear fender of a bicycle is installed on the upright column under the seat or on the rear fork of the frame. When directly installed on the upright column under the seat, the rear fender is connected to the vehicle body only by a circular fixing part, while the rear fender installed on the frame fork can be connected to the vehicle body through two symmetrical brackets, which is not only more stable, but also can adjust the distance between the rear fender and the vehicle body and the inclination angle of the rear fender itself. However, in actual use, the thicknesses of the frame forks of different brands are not the same, and moreover, there are slight differences in the thicknesses of the frame forks of different models of the same brand, which makes the fender bracket highly targeted and low in applicability, and there is room for improvement.

[0022] Embodiment 1, in conjunction with the attached Figure 1 , a rear fender bracket for a bicycle, including symmetrically arranged support components 1 and installation components 2; the installation components can be detachably installed on the rear fork 3, facilitating assembly; the lower ends of the support components 1 are rotatably connected to the corresponding installation components 2 respectively. Since the rear fender body is installed at the upper end of the support component 1, rotating the support component 1 on the installation component 2 can adjust the front and rear installation positions of the rear fender.
[0023] In conjunction with the attached Figure 1 , 4 , the support component 1 includes a hollow cylinder 4. A support rod 5 is slidably arranged at the upper end inside the hollow cylinder 4. There is a telescopic structure between the support rod 5 and the hollow cylinder 4; the telescopic structure includes a threaded neck 6 provided at the end of the hollow cylinder 4 and outside the support rod 5. The outer diameter of the end of the threaded neck 6 away from the hollow cylinder 4 gradually decreases, and several through grooves 7 are arranged along the circumference; an adjusting nut 8 is threadedly connected to the outside of the threaded neck 6. The inner diameter of the end of the adjusting nut 8 away from the threaded neck 6 gradually decreases; by lengthening or shortening the support rod 5, the installation position of the rear fender can also be adjusted; after moving the support rod 5 to an appropriate position, rotate the adjusting nut 8 in the direction away from the support rod 5, so that the end with a smaller inner diameter gradually presses the end with a smaller outer diameter of the threaded neck 6 to complete the extrusion and locking of the support rod 5.
[0024] In conjunction with the attached Figure 1 , 2 , the installation component includes an upper cover 9 and a lower cover 10 that are hinged. Concave parts 21 are provided on the opposite sides of the upper cover 9 and the lower cover 10. The concave parts 21 reduce unnecessary components and weight, facilitating the lightweight of the bicycle and also reducing the stress of mutual extrusion; there is no less than one group of adjustable installation components between the upper cover 9 and the lower cover 10;
[0025] In conjunction with the attached Figure 1 , 2, 3, 5, the adjustable mounting assembly includes a sliding base 11 provided on the outside of the lower cover 10, and an outer housing 12 is slidably provided on the sliding base 11; limiting strips 13 are provided on the outside of one end of the upper cover 9 and the lower cover 10 close to each other; threaded holes are provided on the outer housing 12, and a screw rod 14 is threadedly connected in the threaded holes. The screw rod 14 extends into the outer housing 12 and is rotatably provided with a pressing member 15. The pressing member 15 can cover the limiting strip 13. The longitudinal section of the pressing member 15 is an inverted U shape, and the inner side is an inclined surface; rotating the screw rod 14 to drive the pressing member 15 to move downward can squeeze the two limiting strips 13 toward the middle through the inclined inner side until the upper cover 9 and the lower cover 10 squeeze and fix the rear fork 3.
[0026] Combined with the attached Figure 1 , 2 , 3, a fixing plate 16 capable of being detachably connected to the outer housing 12 is provided on the upper cover 9. Corresponding through holes are provided on the outer housing 12 and the fixing plate 16. A threaded rod is slidably provided in the through holes. The threaded rod extends out of the through holes and is threadedly connected with a nut; even if the rear fork 3 is relatively thick and the outer housing 12 and the fixing plate 16 cannot be completely attached, the connection can be achieved through the threaded rod and the nut; and in this process, the outer housing 12 can slide in the sliding base 11 and move closer to the fixing plate 16 for easy connection.
[0027] Combined with the attached Figure 2 , anti-slip pads 17 are provided inside both the upper cover 9 and the lower cover 10, which can increase the friction with the rear fork 3 and are not easy to slip off.
[0028] Combined with the attached Figure 1 , 2 , 3, a limiting slider is provided below the outer housing 12, and a limiting chute 18 capable of being slidably connected to the limiting slider is provided in the sliding base 11. The longitudinal sections of the limiting slider and the limiting chute 18 are both inverted T shapes, so that the outer housing 12 can move on the sliding base 11 and will not come out.

[0030] Working principle of the utility model: The support component 1 is installed on the rear fork of the bicycle body through the installation component 2. During installation, the hinged upper cover 9 and lower cover 10 are buckled on the outside of the rear fork 3, and the outer protective shell 12 slidably arranged on the sliding base 11 is connected to the fixing plate 16. At this time, the extrusion part 15 is located above and outside the two limiting strips 13. Then rotate the screw rod 14 to drive the extrusion part 15 to move downward, so that the two limiting strips 13 can be squeezed towards the middle through the inclined inner side until the upper cover 9 and the lower cover 10 squeeze and fix the rear fork 3.
[0031] The above describes the utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative purpose of the utility model, they shall fall within the protection scope of the utility model.
