[0002] Bicycles are widely used in daily life as an environmentally friendly and convenient means of transportation. However, during riding, especially in rainy or muddy conditions, the wheels splash mud and water, not only soiling the cyclist's clothes but also potentially affecting the lifespan of bicycle components. To solve this problem, bicycle mudguards were developed.
[0003] In existing technologies, mudguards are mostly fixed structures. The requirements for mudguards vary significantly depending on the riding scenario (commuting, off-road, racing, folding and storage). It is difficult to make flexible adjustments according to different riding scenarios, which makes it difficult to meet the needs of users. Utility Model Content
[0004] The purpose of this invention is to solve the problem of difficulty in flexibly adjusting bicycle mudguards in the prior art, and to propose a movable bicycle mudguard.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a movable bicycle mudguard, comprising a mounting ring, an adjustment frame, and a mudguard body.
[0006] The adjusting frame is fixedly connected to the outer wall of the mounting ring, the mudguard body is fixedly connected to the top of the adjusting frame by bolts, a buffer assembly is fixedly connected to the inner wall of the mounting ring, an opening is provided on the surface of the mounting ring, and a connector is provided on the surface of the opening.
[0007] The adjusting frame includes a first movable block, which is fixedly connected to the outer wall of the mounting ring. An extension rod is rotatably connected to the end of the first movable block away from the mounting ring. A second movable block is movably connected to the extension end of the extension rod. An adjusting hole is provided on the top of the first movable block. The mudguard body is threadedly connected to the adjusting hole through a fixing bolt.
[0008] Furthermore, the extension rod includes a main rod, a telescopic rod is sleeved inside the main rod, the surface of the telescopic rod is provided with a fixing hole, and a fixing plate is threadedly connected to the outer surface of the main rod.

Detailed Implementation
[0023] Please see Figure 1-5 This utility model provides a technical solution: a movable bicycle mudguard, including a mounting ring 1, an adjustment frame 2, and a mudguard body 3.
[0024] The adjusting frame 2 is fixedly connected to the outer wall of the mounting ring 1. The mudguard body 3 is fixedly connected to the top of the adjusting frame 2 by bolts. The inner wall of the mounting ring 1 is fixedly connected to the buffer assembly 4. The surface of the mounting ring 1 has an opening, and the surface of the opening is provided with a connector 5.
[0025] The following section will explain the specific setup and function of the mounting ring 1 and the adjusting bracket 2.
[0026] In this embodiment: the adjustment frame 2 includes a first movable block 21, which is fixedly connected to the outer wall of the mounting ring 1. An extension rod 22 is rotatably connected to the end of the first movable block 21 away from the mounting ring 1. A second movable block 23 is movably connected to the extension end of the extension rod 22. An adjustment hole 6 is provided on the top of the first movable block 21. The mudguard body 3 is threadedly connected to the adjustment hole 6 through a fixing bolt 7.
[0027] The effect achieved by the above components is as follows: through the rotational connection between the first movable block 21 and the extension rod 22, and the movable connection between the extension rod 22 and the second movable block 23, the mudguard body 3 can be adjusted at multiple angles. In addition, with the adjustment hole 6 and the fixing bolt 7, the mudguard body 3 can be fixed in different positions to meet the needs of mudguard angle and position in different riding scenarios, and improve the flexibility and effectiveness of mudguarding.
[0028] Specifically, the extension rod 22 includes a main rod 221, a telescopic rod 222 is sleeved inside the main rod 221, the surface of the telescopic rod 222 is provided with fixing holes, and a fixing plate 223 is threadedly connected to the outer surface of the main rod 221. The fixing plate 223 adjusts the length of the telescopic rod 222 through the fixing holes.
[0029] The aforementioned components achieve the following effect: the sleeve design of the main rod 221 and the telescopic rod 222 allows the length of the extension rod 22 to be freely adjusted. When it is necessary to change the distance between the mudguard body 3 and the wheel, simply pull the telescopic rod 222 to the appropriate length, and then fix it by passing the fixing plate 223 through the corresponding fixing hole. This design allows the mudguard to maintain a good mud-blocking range when facing different road conditions, such as narrow alleys or open highways, while avoiding collisions with other objects.
[0030] Specifically, fastening discs 24 are provided on the surfaces of both the first movable block 21 and the second movable block 23.
[0031] The effect achieved by the above components is as follows: after the angle adjustment between the first movable block 21, the extension rod 22 and the second movable block 23 is completed, the fastening plate 24 can firmly fix their connection parts, preventing the angle from shifting due to vibration or external force during riding. This ensures the stability of the mudguard body 3 position, ensuring that it can always accurately block mud and water, while also reducing wear between components and extending the service life of the adjustment frame 2.
[0032] Specifically, the buffer assembly 4 includes a fixing plate 41 fixedly connected to the inner wall of the mounting ring 1, a buffer spring 42 fixedly connected to the surface of the fixing plate 41, and a buffer plate 43 fixedly connected to the end of the buffer spring 42 away from the fixing plate 41.
[0033] The effect achieved by the above components is as follows: when the bicycle is traveling on a bumpy road, the mounting ring 1 will be subjected to significant vibration. At this time, the buffer plate 43 first comes into contact with the vibration source, transmitting the vibration to the buffer spring 42. The buffer spring 42 absorbs most of the vibration energy through its own elastic expansion and contraction, and then transmits the remaining minor vibration to the mounting ring 1 through the fixing plate 41. This process greatly reduces the impact of vibration on the overall structure of the mudguard, avoids loosening and damage of components due to long-term vibration, effectively protects the mudguard, and extends its service life.
[0034] Specifically, the connector 5 includes connecting pieces 51 fixedly connected to the two sides of the opening, and the connecting pieces 51 are fixedly connected to each other by bolts.
[0035] The aforementioned components achieve the following effects: During installation, the mounting ring 1 is simply slipped onto the bicycle wheel axle through the opening, then the connecting pieces 51 on both sides are aligned and tightened with bolts to complete the fixation. The entire process requires no professional tools, is simple and convenient, and can be easily completed by ordinary people. When the mudguard needs to be removed for cleaning, repair, or replacement, simply loosen the bolts, open the connecting piece 51, and the mounting ring 1 can be removed from the wheel axle, saving time and effort and improving the ease of use of the mudguard.
[0036] Specifically, reflective strips 31 are fixedly connected to both sides of the mudguard body 3, and the reflective strips 31 are symmetrically distributed on the surface of the mudguard body 3.
[0037] The effect achieved by the above components is that when light shines on the reflective strip 31 at night or in dimly lit environments, the reflective strip 31 can reflect the light back, reducing the probability of traffic accidents and providing safety for cyclists traveling at night.
[0038] Working principle: When installing this movable bicycle mudguard, first fix the mounting ring 1 to the bicycle through the connector 5, align the connecting piece 51 and tighten the bolts; after installation, adjust the mudguard body 3 through the adjustment bracket 2 according to the actual riding needs.
[0039] To change the length position of the mudguard body 3, loosen the fixing plate 223 on the extension rod 22, pull the telescopic rod 222 to the appropriate length, and then tighten the fixing plate 223 to fix it. To adjust the longitudinal angle of the mudguard body 3, rotate the connection between the first movable block 21 and the extension rod 22, and the extension rod 22 and the second movable block 23, and fix it with the fastening plate 24 after adjustment. To adjust the lateral angle of the mudguard body 3, change the fixed position of the mudguard body 3 on the first movable block 21 by screwing the fixing bolt 7 into the adjustment hole 6.
[0040] During riding, the buffer component 4 can reduce the impact of vibration on the mudguard, the mudguard body 3 prevents mud and water from splashing up, and the reflective strips 31 on both sides serve as a warning when the light is dim, ensuring riding safety.
