Description

Technical Field

[0001] The utility model relates to an improved carbon fiber spoke structure, in particular to a spoke structure made of carbon fiber material and capable of preventing loosening. Background Art

[0002] In the structure of a bicycle, spokes are an important bridge connecting the hub and the rim. Evenly distributed spokes not only ensure stable rotation of the rim, but also withstand the weight of the bicycle and rider, thereby preventing deformation and damage to the rim. To reduce weight, spokes are made of carbon fiber. However, carbon fiber is difficult to process, so other components must be attached to the ends of the spokes. However, due to the strong rigidity of the carbon fiber spokes, it is not easy to embed the attached components into the spokes. Furthermore, the embedding process can easily cause the ends of the carbon fiber spokes to crack in unspecified directions or locations, which not only affects product yield but also creates hidden dangers in subsequent product use once the spokes are released to the market. Therefore, the combination of the carbon fiber spokes and the attached components is prone to detachment or instability.

[0003] Therefore, how to solve the above problems and deficiencies of the prior art is an urgent research and improvement direction that the inventors of the present invention and related manufacturers engaged in this industry need to focus on. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to better understand the purpose, structure and function of the present invention, the improved structure of the carbon fiber spoke of the present invention is further described in detail below with reference to the accompanying drawings.

[0027] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 As shown in the figure, there are a three-dimensional appearance diagram, a cross-sectional view, a schematic diagram of a preferred embodiment and a schematic diagram of a further embodiment of the present invention. It can be clearly seen from the figure that the carbon fiber spoke 1 of the present invention mainly includes:

[0028] A long rod 2 having a first docking portion 21 at one end and a second docking portion 22 at the other end, wherein the first docking portion 21 has a first pressing portion 211 , and the second docking portion 22 has a second pressing portion 221 ;

[0029] A cap member 3 having a receiving groove 30 in which the first docking portion 21 and the first pressing portion 211 of the long rod 2 can be inserted. The cap member 3 also has a compression portion 31 on the outside.

[0030] A sleeve 4 having an accommodating space 40 in which the second docking portion 22 and the second pressing portion 221 of the long rod 2 can be inserted. The sleeve 4 also has a compression portion 41 on the outside.

[0031] The first pressing portion 211 of the first docking portion 21 corresponds to the compression portion 31 of the head member 3 ;

[0032] The first docking portion 21 has a first adhesive layer 212 ;

[0033] The second pressing portion 221 of the second docking portion 22 corresponds to the compression portion 41 of the socket 4;

[0034] The second docking portion 22 has a second adhesive layer 222 ;

[0035] Among them, a screw lock portion 42 is further provided outside the sleeve 4;

[0036] The carbon fiber spoke 1 of the present invention mainly comprises the following steps: firstly, the first butt joint portion 21 of the long rod body 2 is inserted into the accommodating space 40 of the cap member 3, and then the outer side of the cap member 3 is extruded to form a compression portion 31 on the cap member 3, and at the same time, a first pressing portion 211 is formed on the first butt joint portion 21. Then, the second butt joint portion 22 of the long rod body 2 is inserted into the accommodating space 40 of the socket member 4, and the outer side of the socket member 4 is extruded to form a compression portion 41 on the socket member 4, and at the same time, a second pressing portion 221 is formed on the second butt joint portion 22.

[0037] As described above, since the first pressing portion 211 and the second pressing portion 221 of the long rod body 2 are retracted inwardly and are restricted by the compression portion 31 of the cap member 3 and the compression portion 41 of the sleeve member 4, the first docking portion 21 and the second docking portion 22 of the long rod body 2 can be firmly located in the cap member 3 and the sleeve member 4 respectively;

[0038] In addition, before the first docking portion 21 of the long rod 2 is inserted into the receiving groove 30 of the cap 3, a first adhesive layer 212 is applied to the surface of the first docking portion 21. The adhesiveness of the first adhesive layer 212 further increases the stability between the first docking portion 21 and the cap 3.

[0039] In addition, before the second docking portion 22 of the long rod 2 is inserted into the accommodating space 40 of the sleeve 4, a second adhesive layer 222 is coated on the surface of the second docking portion 22. The viscosity of the second adhesive layer 222 further increases the stability between the second docking portion 22 and the sleeve 4.

[0040] To sum up, compared with the various deficiencies and problems of the existing carbon fiber spoke structure, the carbon fiber spoke 1 of the present invention is specially designed with a long rod body 2, a cap head 3 and a socket 4, so that the first docking portion 21 and the second docking portion 22 at the two ends of the long rod body 2 can be firmly combined with the cap head 3 and the socket 4 respectively. Furthermore, through the extrusion processing procedure, the first docking portion 21 forms a first pressing portion 211 and the cap head 3 forms a compression portion 31, and the second docking portion 22 forms a second pressing portion 221 and the socket 4 forms a compression portion 41 at the same time, which can also greatly reduce the difficulty of the bonding process.
