Description

Technical Field

[0001] This utility model relates to the field of spoke technology, specifically to a long-life spoke with a buffer structure. Background Technology

[0002] Bicycle spokes are an essential component of bicycle wheels, radiating outwards from the hub to the rim, supporting the wheel structure and connecting the rim and hub. Through rim and spoke deformation, they absorb shocks and contribute to weight reduction. Current spoke installation involves spoke caps tensioned between the hub and rim, inserted into holes on the rim and secured to the spokes with threads. This installation structure maintains rigid contact between the spoke cap and rim, and between the spokes and hub, relying solely on the spokes' own elasticity to resist elastic deformation during rim movement. When encountering bumpy road conditions, especially on some high-performance sports bikes, the lack of cushioning makes the spokes prone to breakage, shortening their lifespan. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a long-life spoke with a buffer structure. Technical solution

[0004] A long-life spoke with a buffer structure includes a first spoke body, a second spoke body, and a connecting assembly. The connecting assembly includes a first sleeve and a second sleeve, which are connected by threads. The first spoke body has a first locking head and a first external thread at both ends, with the first external thread connecting to a first locking member. The second spoke body has a second locking head and a second external thread at both ends, with the second external thread connecting to a second locking member. The first locking member and the second locking member are movably connected inside the first sleeve and the second sleeve, respectively. Both ends of the first sleeve and the second sleeve have through holes through which the first spoke body and the second spoke body can pass. An elastic buffer ball is provided between the first locking member and the second locking member.

[0005] Furthermore, a first elastic washer is provided between the inner walls of the ends of the first clamp and the first sleeve, and the first elastic washer is fixedly sleeved on the first clamp; a second elastic washer is provided between the inner walls of the ends of the second clamp and the second sleeve, and the second elastic washer is fixedly sleeved on the second clamp.

[0006] Preferably, the first and second clips are respectively provided with slots corresponding to the first and second elastic washers.

[0007] Furthermore, both the first and second locking components include a hemispherical head and a cylindrical tail. The head is slidably connected to the first and second sleeves, and the curved surface of the tail is provided with a first operating part.

[0008] Furthermore, the outer surfaces of the first sleeve and the second sleeve are provided with a second operating part.

[0009] Furthermore, both the first and second operating parts are composed of multiple cutting surfaces, which are arranged in a regular polygonal structure. More preferably, they are square, pentagonal, or hexagonal in shape.

[0010] Furthermore, the first spoke body is a cylindrical structure and the end with the first clamp is bent at 90°, and the second spoke body is a cylindrical structure.

[0011] Beneficial effects:

[0012] This invention provides a long-life spoke with a buffer structure. During installation, the first and second spoke bodies are inserted into the insertion holes of the wheel hub and rim, respectively. The first and second locking heads are secured to the outside of the corresponding insertion holes. The other ends of the first and second spoke bodies are then inserted into the first and second sleeves, respectively. After installing the first and second elastic washers, the first and second locking members are tightened. An elastic buffer ball is placed inside the first or second sleeve, and the first or second sleeve is rotated to tension the first and second spoke bodies between the wheel hub and rim. Because this invention incorporates an elastic buffer ball, a first elastic washer, and a second elastic washer, it effectively resists elastic deformation during rim movement, resulting in a longer service life and effectively tensioning the spokes to prevent loosening.

[0015] The present invention will now be described in detail with reference to the accompanying drawings.

[0016] As attached Figure 1 To be continued Figure 3 . Specific implementation examples:

[0018] A long-life spoke with a buffer structure includes a first spoke body 1, a second spoke body 2, and a connecting assembly. The connecting assembly includes a first sleeve 3 and a second sleeve 4, which are connected by threads (details not shown in the figure). The first spoke body 1 has a first locking head 5 and a first external thread at both ends, and the first external thread connects to a first locking member 6. The second spoke body 2 has a second locking head 7 and a second external thread at both ends, and the second external thread connects to a second locking member 8. The first locking member 6 and the second locking member 8 are movably connected inside the first sleeve 3 and the second sleeve 4, respectively. The ends of the first sleeve 3 and the second sleeve 4 are provided with through holes, through which the first spoke body 1 and the second spoke body 2 can pass. An elastic buffer ball 9 is provided between the first locking member 6 and the second locking member 8.

[0019] Preferably, a first elastic washer 10 is provided between the inner walls of the ends of the first locking member 6 and the first sleeve 3, and the first elastic washer 10 is fixedly sleeved on the first locking member 6; a second elastic washer 11 is provided between the inner walls of the ends of the second locking member 8 and the second sleeve 4, and the second elastic washer 11 is fixedly sleeved on the second locking member 8. As an embodiment of the present invention, the first locking member 6 and the second locking member 8 are respectively provided with slots (not shown in the figure) corresponding to the first elastic washer 10 and the second elastic washer 11.

[0020] When installing the spokes of this utility model, first insert the first spoke body 1 and the second spoke body 2 into the insertion holes of the wheel hub and the wheel rim, respectively. The first locking head 5 and the second locking head 7 are locked on the outside of the corresponding insertion holes. Then, insert the other ends of the first spoke body 1 and the second spoke body 2 into the first sleeve 3 and the second sleeve 4, respectively. After installing the first elastic washer 10 and the second elastic washer 11, tighten the first locking member 6 and the second locking member 8. At this time, the first locking member 6 and the second locking member 8 are stably connected with the first spoke body 1 and the second spoke body 2, respectively. Then, place the elastic buffer ball 9 into the first sleeve 3 or the second sleeve 4, and start rotating the first sleeve 3 or the second sleeve 4 until the first spoke body 1 and the second spoke body 2 are tensioned between the wheel hub and the wheel rim. The preferred state is that when fully tensioned, the first locking member 6 and the second locking member 8 just contact the elastic buffer ball 9 or slightly compress the elastic buffer ball 9. Because this utility model is equipped with an elastic buffer ball 9, a first elastic washer 10 and a second elastic washer 11, it can effectively resist the elastic deformation during the movement of the rim, has a longer service life, and can effectively tension the spokes to prevent loosening.
