[0023] The following only uses embodiments to illustrate possible implementation modes of the present invention, but is not intended to limit the scope to be protected by the present invention. The "one" or "at least one" prefixed to the nouns mentioned in the text does not limit the quantity. According to requirements, it can also be "plural" ones. Such changes in quantity are also within the scope to be protected. This is stated first for clarification.

[0024] Please refer to Figures 1 to 6 , which shows a preferred embodiment of the present invention. The wire threading device 1 for a bicycle of the present invention includes a pipe member 10 and at least one kit 20.

[0025] The pipe member 10 includes at least one through hole 11 and at least one hole wall 12 surrounding the at least one through hole 11; at least a part of the at least one kit 20 is disposed in the at least one through hole 11; wherein, the pipe member 10 and the at least one kit 20 are made of different materials; when viewed along an axial direction of the at least one through hole 11, a wire threading hole 30 for a wire 2 to pass through is jointly formed between each kit 20 and one of the hole walls 12. Thus, the at least one through hole 11 can be formed in the pipe member 10 by broaching or other conventional processing methods, and the at least one kit 20 can prevent the wire 2 from contacting an edge 121 of the at least one hole wall 12, achieving the effect of protecting the wire 2 and being easy to process.

[0026] Preferably, the hardness of the at least one kit 20 is less than the hardness of the pipe member 10, and the protection effect is good. For example, the pipe member 10 can be made of materials such as iron, aluminum alloy, carbon fiber, etc., and the at least one kit 20 can be made of materials such as silica gel, plastic, rubber, etc., and can be formed into a required configuration according to requirements, which is convenient for manufacturing and installation. It should be particularly noted that compared with the prior art, the processing of each through hole 11 can be simplified, and the at least one kit 20 and the at least one hole wall 12 are cooperated to surround the required wire threading holes 30, which is convenient for processing and easy to change the configuration. In other embodiments, the at least one kit can also be made of a metal material and can be selected according to requirements.

[0027] Each kit 20 is flush with or protrudes from at least one end port of one of the through holes 11; in a radial direction of the at least one hole wall 12, each kit 20 extends along at least 1 / 3 of the edge 121 of the one hole wall 12, effectively preventing the wire 2 from contacting the edge 121 of the at least one hole wall 12. Preferably, in the axial direction, the height of the at least one kit 20 at least partially corresponds to the height change of the at least one hole wall 12, as Figure 4 shown, to avoid the at least one kit 20 protruding too much and hindering wire threading.

[0028] Specifically, each of the kits 20 includes a socket portion 21 and a snap portion 22. The socket portion 21 at least partially extends corresponding to the at least one through hole 11 and is located within the at least one through hole 11. The snap portion 22 extends transversely to the socket portion 21 and can abut against an outer surface of the pipe fitting 10 around the at least one through hole 11, facilitating assembly. Preferably, the pipe fitting 10 further includes at least one slot 13 adjacent to the at least one through hole 11. The snap portion 22 of each kit 20 can be received in one of the slots 13, achieving a positioning effect and facilitating subsequent assembly. Each of the kits 20 can also be attached to the pipe fitting 10 with an adhesive, having good stability and not easily falling off.

[0029] Furthermore, the pipe fitting 10 includes a first hole groove 14 and a second hole groove 15 transverse to the first hole groove 14. The at least one through hole 11 is provided on a side of the first hole groove 14 adjacent to the second hole groove 15 and communicates with the second hole groove 15. The at least one kit 20 is located on a side of the at least one through hole 11 away from the first hole groove 14. Thus, when the wire 2 is bent and extends from the second hole groove 15 towards the first hole groove 14, the wire 2 can abut against the at least one kit 20 without contacting the edge 121 (cutting edge) of the at least one hole wall 12, thereby effectively avoiding frictional damage. In this embodiment, the pipe fitting 10 is a handlebar riser. The first hole groove 14 is a fixing hole for connecting a steering tube. The second hole groove 15 extends open towards a side away from the fixing hole and can be used to connect a handlebar. The brake wire or shift wire of the bicycle can extend from the second hole groove 15 towards the hole groove to the steering tube, as Figure 3 shown, facilitating wiring.

[0030] Furthermore, the pipe fitting 10 includes two non - communicating through holes 11. The socket portion 21 includes two lugs 211 respectively passing through the two through holes 11. The snap portion 22 is connected to the two lugs 211 at intervals, as Figure 5 and Figure 6 shown. Thus, the plurality of wires 2 can be distributed into two non - communicating threading holes 30 as required, reducing mutual interference. The at least one slot 13 is adjacent to an end of the two through holes 11 relatively far from the second hole groove 15 and communicates with the two through holes 11; each of the lugs 211 at least partially extends in an arc corresponding to one of the hole walls 12, facilitating manufacturing, installation and having good bonding stability. In this embodiment, the two lugs 211 and the snap portion 22 are a single integrally injection - molded member, having good structural strength and being easy to manufacture; the thickness of each of the lugs 211 gradually decreases towards the opposite two sides of the lug 211 to smoothly connect with one of the hole walls 12, preventing the wire 2 from being stuck at the connection between the two, ensuring smooth operation.

[0031] With reference to Figure 4, when viewed axially along the second hole groove 15, the two lugs 211 protrude into the second hole groove 15. Thus, when the handle riser rotates relative to the steering tube, the wire 2 and the edges 121 of the hole walls 12 are separated by the protruding two lugs 211, effectively avoiding cutting the wire 2. Preferably, the at least one set of parts 20 does not protrude from the outer surface of the pipe fitting 10, which has good aesthetics. In other embodiments, the two lugs may also be flush with the at least one hole wall 12 without protruding relatively; each through hole may be respectively provided with one set of parts.

[0032] The above is the preferred embodiment of the present invention and the technical principles applied thereto. For those skilled in the art, any obvious changes such as equivalent transformations and simple substitutions based on the technical solution of the present invention without departing from the spirit and scope of the present invention shall fall within the protection scope of the present invention.
