Abstract
The utility model is a spoke structure for bicycle, comprising a middle section, a head section which is arranged at one end of the middle section, a thread section which is arranged at the outer edge of the other end of the middle section. A flat-bending part or a flat-shaped neck part is connected between the middle section and the head section. The middle section of the spoke is provided with a flat part near the thread section. The spoke has better hardness and flexibility to improve practical effectiveness because the spoke bears three-axis direction force when revolving.
Description
Technical field
The spoke structure of the relevant a kind of bicycle of the utility model refers to that especially a kind of reaching has preferable hardness and the elasticity spoke structure with the practical effect that promotes spoke.
Background technology
The elbow spoke 5 of general known bicycle, as shown in figure 10, it is to be arranged at the threaded portion 53 of center section part 51 other end outer rims and to be located at center section part 51 and the elbow portion 54 of 52 on head is constituted by the head 52, that a center section part 51 and is arranged at center section part 51 1 ends;
The straight peen spoke 6 of another known bicycle for another example, as shown in figure 11, it is to be arranged at the threaded portion 63 of center section part 61 other end outer rims and to be located at center section part 61 and the neck 64 of 62 on head is constituted by the head 62, that a center section part 61 and is arranged at center section part 61 1 ends;
Thus, can be for (scheming not show) between the colored hub and wheel rim that this elbow spoke 5 and straight peen spoke 6 are arranged at the bicycle wheels, to reach the effect that the required tension force of wheels is provided.
And owing to this spoke the 5, the 6th, be arranged between the colored hub and wheel rim of wheels, provide wheels required tension force to reach, but in fact, because of the purposes difference, the wheels that various bicycle adopted are also different, and for example racing machine needs the strong wheels of rigidity, the descending car is the good wheels of elasticity of demand then, the wheels distortion that rigidity is strong is little, the labour-saving advantage is arranged, and the adaptation Z-TEK of the wheels road conditions of good springiness is good; Therefore, the hardness of this spoke 5,6 and elasticity are promptly quite important, and with above-mentioned known elbow spoke 5 its when stressed this elbow portion 54 bear from the level of flower hub to and moment longitudinally, this center section part 51 bears moment longitudinally, threaded portion 53 then bear from the level of wheel rim and spoke cap to and moment longitudinally.Again with straight peen spoke 6 its when stressed this head 62 bear from the level of flower hub to and pulling force longitudinally, this neck 64 bear equally level to and moment longitudinally, threaded portion 63 then bear from the level of wheel rim and spoke cap to and moment longitudinally.
Therefore, when causing spoke 5,6 to bear excessive external force, very easily by junction and the elbow portion 54 centre fracture of head 52, or by junction and the threaded portion 63 centre generation fracture of neck 64, so the structural strength of known spoke 5,6 is obviously not enough with head 62 with elbow portion 54.So, cause the known spoke 5,6 can't realistic use needs.
Summary of the invention
The purpose of this utility model is to solve above-mentioned disappearance, can be by plat part and the flat-shaped kink between center section part and head or the flat-shaped neck of adjacent threads portion on the spoke center section part, three is axial stressed when making spoke in response to start, has preferable hardness and elasticity to promote the practical effect of spoke and reach.
In order to achieve the above object, the spoke structure of a kind of bicycle of the present utility model, this spoke includes a center section part, one end of this center section part is provided with a head, and the other end outer rim of this center section part has a threaded portion, and be connected with a flat-shaped kink or flat-shaped neck between this center section part and the head, and the position of adjacent threads portion has a plat part on this center section part.
In sum, the spoke structure of bicycle of the present utility model can effectively be improved known various shortcoming, can be by plat part and the flat-shaped kink between center section part and head or the flat-shaped neck of adjacent threads portion on the spoke center section part, three is axial stressed when making spoke in response to start, have preferable hardness and elasticity promoting the practical effect of spoke and reach, and reach the practical effect that promotes spoke.

The specific embodiment
See also Figure 1 and Figure 2, be respectively the front elevation of the utility model first embodiment and the lateral plan of the utility model first embodiment.As shown in the figure: the spoke structure of bicycle of the present utility model, this spoke 1 includes a center section part 11, one end of this center section part 11 is provided with a head 12, and the other end outer rim of this center section part 11 has a threaded portion 13, and between this center section part 11 and head 12, be connected with a flat-shaped kink 14, this flat-shaped kink 14 is behind bending forming, imposing a suitable external force with required mould is again constituted, and this flat-shaped kink 14 can be the flats of left and right two sides, to form an elbow spoke 1.(not shown) when the head 12 of this spoke 1 and threaded portion 13 are arranged at the colored hub of wheel and wheel rim can utilize the ora terminalis of flat-shaped kink 14 corresponding with the flower hub, with the rigidity of increase spoke 1 practical effect with the lifting spoke.
See also Fig. 3 and shown in Figure 4, be respectively the front elevation of the utility model second embodiment and the lateral plan of the utility model second embodiment.As shown in the figure: this flat-shaped kink 14a of the present utility model can be the flats on forward and backward two surfaces, after this flat-shaped kink 14a causes type in breaking, again with required mould, imposes a suitable external force bending and forms; And when the head 12 of this spoke 1 and threaded portion 13 are arranged at the colored hub of wheel and wheel rim (not shown), can utilize the flat horizontal surface of flat-shaped kink 14a corresponding, with the elasticity of increase spoke 1 practical effect with the lifting spoke with the flower hub.
