Problems solved by technology

[0004] However, the distance between the protrusions of the two opposite chain pieces in the prior patent is still the same, so there will also be different gaps in which the sprocket teeth of the guide wheel and the transmission chainring are inserted into the two chain pieces, which will affect To the demerit existence of the shifting function

Embodiment Construction

[0048] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0049] see figure 1 As shown, the first embodiment of the present invention includes a chain body 1 and a bushing 2, wherein:

[0050] The chain piece body 1 is provided with an action surface 11 that can face another chain piece body 1, and the chain piece body 1 is respectively provided with a circular joint portion 12 at both ends of the action surface 11, the joint portion 12 is provided with a through shaft hole 13, the periphery of the shaft hole 13 is provided with a ring protrusion 14, and the chain piece body 1 is respectively provided with a first engaging surface 15 on the working surface 11 between the two joint parts 12 and the second clamping surface 16, a limit block 17 is provided on the working surface 11 adjacent to the first clamping surface 15, the height of the limit block 17 is higher th...

Abstract

The invention relates to a chain-sheet structure provided with double spaces. A limiting block is arranged at the adjacent position between an acting surface of a chain-sheet body and a first clamping face, and the height of the limiting block is larger than that of the acting surface; a lining is connected to each annular protrusion in an assembled mode, a hole is formed in each lining, and the maximum diameter of each hole is larger than that of the corresponding annular protrusion; two chain-sheet bodies can be assembled relatively, so that a first space is formed between the acting surfaces of the two chain-sheet bodies, the limiting block is used for narrowing the first space, and the linings move on combined parts in a limited mode for forming a second space. By means of the structure, the advantages of changing speed stably and fast and avoiding noise can be achieved.

Description

technical field [0001] The present invention relates to a chain piece structure with double spaces, in particular to a chain piece structure with two spaces after assembly, which helps to achieve the advantages of stable, fast and noise-free shifting. Background technique [0002] For the chain structure commonly used for bicycle speed change at present, please refer to Figure 15 As shown, it uses a chain A to pass through a transmission guide wheel B and a speed change chainring C, so as to be used for transmission and speed change, but because the gap between each pair of chain pieces A1 of the chain A is fixed, and The sprocket B1 of the guide wheel B and the sprocket C1 of the transmission chainring C have different thicknesses, so the sprocket B1 of the guide wheel B and the sprocket C1 of the transmission chainring C are respectively inserted into the chain A. The gaps in the two chain pieces A1 will be different, either too loose or too tight, which will affect the f...
