Description

Technical Field

[0001] The utility model relates to a bicycle spoke and a spoke connecting piece. Background Art

[0002] Bicycle spokes are an important part of bicycle wheels. They radiate outward from the hub (center of the rim) to the rim (edge ​​of the rim), supporting the wheel structure and connecting the rim to the hub.

[0003] Reference Figure 2 and Figure 3 The original anti-tension piece of the spoke is a separate type. During installation, the first connecting piece is first put on the spoke, and then the anti-tension piece is put on the spoke and inserted into the first connecting piece. Subsequently, the threaded end of the first connecting piece is threadedly connected to the wheel hub to complete the installation of the spoke connecting piece. The inventor found that during use, the wheel hub adjusts the spokes, and as the spokes are adjusted, the gap between the separate anti-tension piece will become larger, thereby causing the spoke connecting piece to loosen, which is not conducive to the use of the spokes, thereby causing the spokes to directly detach from the hub, posing certain hidden dangers. Utility Model Content

[0025] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] Reference Figure 1-3 As shown, a spoke connecting member includes

[0027] A spoke body 1, a first connecting end 2 and a second connecting end 9 provided on the spoke body 1;

[0028] A first connecting member 4 is sleeved on the first connecting end portion 2, and one end of the first connecting member 4 is connected to the hub 6 via a thread 7;

[0029] The second connecting member 5 is disposed between the first connecting member 4 and the first connecting end portion 2 to prevent the first connecting member 4 from loosening;

[0030] The third connecting member 8 is disposed at the other end of the spoke body 1 .

[0031] The second connecting member 5 is in the shape of a cylinder or a split cylinder. In order to ensure that the second connecting member 5 is not easy to fall off from the spokes. In one embodiment, the second connecting member 5 is in the shape of a cylinder, which is adapted to the first connecting end 2, and when the wheel hub 6 is adjusted, the second connecting member 5 and the first connecting end 2 are not easy to fall off.

[0032] Furthermore, the first connecting end 2 also includes an arc-shaped portion (not shown in the figure), which is a small section that transitions the first connecting end 2 to the second connecting end 9, and forms a height difference between the arc-shaped portion and the first connecting end 2, so that the second connecting member 5 is tightened. Compared with the existing separate anti-tensioning parts, the anti-tensioning part (second connecting member) is set as an integrated type in this case. When installing the anti-tensioning part, the first connecting member 4 is pre-mounted on the second connecting end 9, and then the anti-tensioning part is mounted between the first connecting end 2 and the second connecting end 9. Then, the anti-tensioning part is extruded into a shape identical to the first connecting end 2 and the second connecting end 9 (transition section) through the existing extrusion equipment, and the anti-tensioning part is fitted with the transition section. Finally, the first connecting member 4 is pulled, and the anti-tensioning part enters the interior of the first connecting member 4 and fits it, so as to ensure that the first connecting member 4 will not fall off and is relatively tight.

[0033] Furthermore, the first connecting end portion 2 is shrunk from the outside to the inside into a cone shape. The advantage of such a setting is that it can more closely fit the spoke hole on the hub, provide better fixation and support, and at the same time, it can help to more evenly distribute the stress on the spoke, reduce stress concentration points, thereby improving the durability of the spoke, and can also easily pass through the spoke hole on the rim and be fastened at the hub end, simplifying the installation process. At the same time, the local strength of the spoke can be improved by increasing the thickness of the material at the connection point, which also helps to optimize the force transmission path, so that the spoke performs better when subjected to bending and torsion. Finally, it can also allow the spoke to adapt to hub holes of different sizes, increasing the versatility of the spoke.

[0034] The radius of the first connecting end 2 is R1, and the radius of the second connecting end 9 is R2, wherein R1:R2 is 1.1:1. The advantage of such a setting is that the friction between the first connecting member 2 or the second or third connecting member 8 and the spoke can be increased, further increasing stability.

[0035] The utility model also provides a bicycle spoke having any one of the spoke connecting pieces mentioned above.

[0036] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
