Description

Bicycle spoke composite structure

The invention relates to the technical field of bicycles, in particular to the technical scope of a composite structure of bicycle spokes.

According to the bicycle spokes, the spokes are thin wires, and the spokes are connected between the hub and the rim. In particular, a hole is formed in the hub flange for receiving the inner end of the spoke strip. In general, the outer end of each spoke strip is threaded such that the outer end can engage a spoke nipple that secures the outer end of the thin wire spoke strip to the spoke rim of the rim.

In modern times, composite materials are widely used in bicycle frames, rims, etc. due to their excellent strength and light weight. Referring to FIG. 5, a conventional spoke strip 9, such as the "new spoke spoke" of the domestic new patent No. M347300, discloses a composite rod 91 having two ends; two are respectively disposed at the two ends of the composite rod 91. The head 92 has an axial passage 921; a hub joint 93 that is consistently disposed in the axial passage 921 of any of the joints 92 and a wheel that is consistently disposed in the axial passage 921 of the other joint 92. Ring connector 94.

However, the aforementioned composite rod body 91 can be cut to an appropriate length as needed, so that the spoke strip 9 can be made to a desired length and size as needed. In addition, the hub joint 93 and the rim joint 94 of the spoke strip 9 can be slightly adjusted to extend or insert the length to finely adjust the length of each spoke strip 9.

However, the aforementioned hub joint 93 and the rim joint 94 are adhesively connected to the axial passage 921 of each joint 92; in other words, the glue work must be used in conjunction with the fixture, so the conventional spoke strip 9 group is known. It is quite cumbersome to install; in addition, the joint 95 of the two different materials (shown by the thick line in Fig. 5) is easy to withstand shear damage, which causes the hub joint 93 and the rim joint 94 to be easily released. The composite rod 91 makes the risk of riding a bicycle very high.

In view of the various problems of the conventional composite spokes, the novel creator has created a bicycle spoke splice composite structure, so the main purpose of the novel is to: a bicycle spoke spoke composite structure with simple process; the second of the novel The purpose is to provide a bicycle spoke composite structure with large structural strength.

In order to achieve the above object, the bicycle spoke spoke composite structure adopts the following technical means, which comprises: a bicycle spoke spoke composite structure, comprising: a hollow rod formed by a composite material having a first inner diameter a hollow rod body; at least one dental sleeve is respectively sleeved on at least one end of the hollow rod, and the inner sleeve is provided with an inner thread and an outer diameter is preset; a flower drum fixing member is one end of the hollow rod The other end is connected to the non-toothed end of the hollow rod; and one of the wheel fixing members is provided with an external thread, and the external thread is connected to the internal thread of the tooth sleeve.

The bicycle spoke spoke composite structure is provided with two tooth sleeves respectively sleeved on the two ends of the hollow rod, and the flower drum fixing member is provided with a head at one end and an external thread at the other end. The external thread is attached to the internal thread of one of the dental sleeves.

The hollow rod is further provided with a second inner diameter, and the second inner diameter is larger than the first inner diameter to form a falling shoulder, and the second inner diameter is equal to the length of the dental sleeve.

The hollow rod is made of a carbon fiber material, and the dental tube, the hub fixing member and the rim fixing member are made of a metal material.

The second inner diameter of the hollow rod is slightly smaller than the outer diameter of the dental sleeve, so that the dental sleeve is tightly fitted to the second inner diameter of the hollow rod.

The second inner diameter of the hollow rod is slightly larger than or equal to the outer diameter of the dental sleeve, so that the dental sleeve can be glued to the second inner diameter of the hollow rod.

The hub fixing member is set as a straight rod member; or the head of the hub fixing member is bent.

When the external thread of the hub fixing member and the rim fixing member is screwed to the internal thread of the corresponding tooth sleeve, the external thread and the internal thread are glued and fixed.

Compared with the prior art, the novel bicycle spoke composite structure has the following effects:

1. In the process of the present invention, it is not necessary to use a jig, and only the external thread of the hub fixing member, the rim fixing member and the internal thread of the corresponding tooth sleeve are used to adjust the length of the required spoke strip to suit different sizes. The bicycle rim of the specification has a simple manufacturing process and does not need to be used with the jig; however, if necessary, the glue can be glued between the outer screw and the inner screw to improve the stability of the screw connection.

2. The joint of the two different materials of the hollow tube and the dental tube sleeve is provided with a falling shoulder, and the falling shoulder has to bear against the dental sleeve, thereby sharing the bearing capacity of the dental sleeve, so that the dental sleeve is not Easy to damage.

3. The new type can also make the length of the hollow tube fixed, and match the length of the hub fixing member or/and the rim fixing member according to the demand, thereby adjusting the spokes of various lengths to assemble the bicycle rims of different sizes and specifications. .
