Anti-loosening improved structure of carbon fiber spoke

Abstract

The invention relates to an improved anti-loosening structure of a carbon fiber spoke, which comprises a cap piece and a carbon fiber spoke, and is mainly characterized in that a sleeving part of the carbon fiber spoke enters an accommodating space of the cap piece from a guide channel of the cap piece, and then the carbon fiber spoke is rotated; the two corresponding inclined parts of the carbon fiber spokes correspond to the two abutting parts of the cap piece, and due to the fact that the two inclined parts of the carbon fiber spokes are limited and pressed by the two abutting parts, the sleeving parts of the carbon fiber spokes are arranged in the containing space of the cap piece to be fixed and not disengaged. Therefore, the purpose of preventing the cap piece and the carbon fiber spokes from being loosened can be achieved.

Description

Technical Field

[0001] The present invention relates to an improved structure for preventing carbon fiber spokes from loosening, and in particular to a spoke structure capable of preventing loosening and enhancing stability. Background Art

[0002] Cycling has become increasingly popular in recent years, leading many manufacturers to invest in the research, development, and production of bicycles. However, to reduce weight, spokes are often made of carbon fiber. However, carbon fiber is difficult to process, so additional components must be attached to the ends of the spokes. However, due to the strong rigidity of the carbon fiber spokes, embedding these components into the spokes is not easy. Furthermore, the embedding process can easily cause the spokes to crack in unspecified directions or locations, impacting product yield and potentially creating safety risks. Therefore, it's easy for the carbon fiber spokes and the attached components to become detached or unstable.

[0003] Therefore, how to solve the above-mentioned problems and deficiencies of the prior art is an urgent research and improvement direction for the inventors of the present invention and related manufacturers engaged in this industry. Summary of the Invention

[0005] To achieve the above purpose, the specific technical solutions of the present invention are as follows:

[0006] An improved structure for preventing carbon fiber spokes from loosening includes a cap having an interior containing a housing and an exterior containing two corresponding recesses. The two recesses form a guide channel at corresponding positions within the housing, and two corresponding stoppers are provided between the housing and the guide channel.

[0007] A carbon fiber spoke has a sleeve portion at one end, and two corresponding inclined portions are formed between the sleeve portion and the carbon fiber spoke. The sleeve portion is embedded in the accommodating space of the cap head.

[0008] Furthermore, the width of the guiding channel is smaller than the width of the accommodating space.

[0009] Furthermore, when the sleeve portion of the carbon fiber spoke is embedded in the accommodating space of the head piece, the two inclined portions of the carbon fiber spoke correspond to the two stopping portions of the head piece.

[0010] Furthermore, the socket portion of the carbon fiber spoke is elliptical in shape, having a narrow side and a wide side.

[0011] Furthermore, an adhesive layer is provided on the surface of the sleeve portion of the carbon fiber spoke.

[0012] Through the above design scheme, the present invention can bring the following beneficial effects:

[0027] In order to better understand the purpose, structure and function of the present invention, the improved structure for preventing the carbon fiber spokes from loosening of the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown in the figure, there are a three-dimensional appearance diagram, a cross-sectional diagram, 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 present invention mainly includes:

[0029] A cap head 1 has an internal accommodating space 10 and two corresponding recesses 11 on its external side. The two recesses 11 form a guide channel 12 at corresponding positions within the accommodating space 10, and two corresponding stoppers 111 are provided between the accommodating space 10 and the guide channel 12.

[0030] A carbon fiber spoke 2, one end of which is provided with a sleeve portion 21, and two corresponding inclined portions 22 are formed between the sleeve portion 21 and the carbon fiber spoke 2. The sleeve portion 21 is embedded in the accommodating space 10 of the headpiece 1;

[0031] The width of the guiding channel 12 is smaller than the width of the accommodating space 10;

[0032] When the sleeve portion 21 of the carbon fiber spoke 2 is embedded in the accommodating space 10 of the headpiece 1 , the two inclined portions 22 of the carbon fiber spoke 2 correspond to the two stop portions 111 of the headpiece 1 .

[0033] The sleeve portion 21 of the carbon fiber spoke 2 is elliptical in shape, having a narrow side 211 and a wide side 212;

[0034] The surface of the sleeve portion 21 of the carbon fiber spoke 2 is provided with an adhesive layer 23;

[0035] The present invention mainly involves firstly inserting the sleeve portion 21 of the carbon fiber spoke 2 into the accommodating space 10 of the head member 1 through the guide channel 12 of the head member 1, and then rotating the carbon fiber spoke 2 so that the two oblique portions 22 of the carbon fiber spoke 2 correspond to the two stop portions 111 of the head member 1. Since the two oblique portions 22 of the carbon fiber spoke 2 are restricted and pressed by the two stop portions 111, the sleeve portion 21 of the carbon fiber spoke 2 is restricted in the accommodating space 12 of the head member 1, thereby achieving the purpose of firmly combining the head member 1 and the carbon fiber spoke 2.

[0036] As described above, since the sleeve portion 21 of the carbon fiber spoke 2 is elliptical in shape, when the sleeve portion 21 of the carbon fiber spoke 2 enters the guide channel 12 of the head member 1, the narrow side 211 of the sleeve portion 21 and the two recessed portions 11 of the head member 1 must be perpendicular to each other so that the sleeve portion 21 can pass through the guide channel 12. After the sleeve portion 21 passes through the guide channel 12 and enters the accommodating space 12, the carbon fiber spoke 2 is rotated so that the wide side 212 of the sleeve portion 21 and the two recessed portions 11 of the head member 1 are perpendicular to each other. In this way, the two oblique portions 22 of the carbon fiber spoke 2 can be restricted and pressed by the two stop portions 111.

[0037] In addition, an adhesive layer 23 is provided on the surface of the sleeve portion 21 of the carbon fiber spoke 2. The adhesive layer 23 is mainly used to further enhance the stability of the connection between the cap 1 and the carbon fiber spoke 2 through the viscosity of the adhesive layer 23.

[0038] In the above embodiment, although the two oblique portions 22 of the carbon fiber spokes 2 are restricted and pressed by the two stop portions 111 by rotating the carbon fiber spokes 2, thereby achieving the purpose of combining the cap member 1 and the carbon fiber spokes 2, however, if the carbon fiber spokes 2 cannot be rotated due to other factors during actual processing, the same purpose can also be achieved by rotating the cap member 1. It only makes a corresponding rotation action when the carbon fiber spokes 2 or the cap member 1 is in a fixed position, and does not change the structural characteristics of the cap member 1.

[0039] In addition, if Figure 9 FIG. 2 is a further embodiment of the present invention, in which the two recesses 11 of the head member 1 are of another type. The two recesses 11 extend directly to the bottom of the head member 1 and form a guide channel 12 at a corresponding position of the accommodating space 10.

[0040] In summary, compared to the various deficiencies and unresolved problems of existing carbon fiber spoke fixing methods, the present invention utilizes a special design of the cap head 1 and the carbon fiber spoke 2 to enable the cap head 1 and the carbon fiber spoke 2 to be stably combined with each other. Furthermore, the rotational fixing method can greatly reduce the processing procedures for the combination.
