Improved bicycle hub structure

Abstract

The invention relates to an improved bicycle hub structure, the body of which is provided with a central shaft tube; the two ends of the central shaft tube are provided with faceplates; the faceplates and end faces corresponding to the faceplates are set as an inner side, contrarily, set as an outer side, wherein, the central shaft tube is a faceplate which links the two ends and the central shaft tube has a hollow tube-shaped structure; the hollow part in the central shaft tube is set as a storage tank; the periphery of the faceplate is concavely provided with a plurality of mounting holes which are opened roughly along the axial parallel direction of the central shaft tube; the surface of the faceplate is concavely provided with a positioning slot which is communicated with the mountingholes; the two sides of the positioning slot with two ends passing through the faceplate and being far from the inner side and the outer side are provided with openings; therefore, the mounting holesare used for the arrangement of spokes; the mounting holes are used for clamping the spokes; moreover, the positioning slot is used for the holding and fixation of a spoke rod-shaped part, so the spokes can be quickly arranged on the body so as to achieve the function of rapid assembly. The invention can reduce the stress concentration of the spokes, prolong the service life and achieve easy assembly.

Description

technical field [0001] The invention relates to an improved bicycle hub structure. Background technique [0002] The hub of a general bicycle is equipped with spokes, and the spokes pass through the hub and the annular rim of the tire to apply tension, so as to combine the hub and the rim into one body, wherein one end of the spoke is equipped with a joint, and is fitted by the joint In the spoke hole of the rim, the front end of the other end is bent into a J-shape, and passes through the spoke hole opening on the hub flange, so that the large diameter part of the front end of the end part is buckled to the flange part, such as in Taiwan, China Application No. 093213366 "Bicycle Hub Steel Wire Combination Structure Improvement" patent, it is mainly in the perforation of the ring ring array expanded at both ends of a sleeve-shaped drum body, which can be used for threading and hooking steel wires; it is characterized in that: the horizontal tube The two ends of the drum-sha...

Problems solved by technology

[0006] Although this can improve the stress concentration problem of a single spoke in the existing structure, but the spokes at both ends are installed at one time, which increases the cost of the spokes, especially the spokes that are bent into a V shape require special processing, and the V shape increases the space occupied by the spokes, resulting in The problem of storage and storage is still inconvenient to use;
