Abstract

A chain disc convenient to install for the bicycle comprises a disc body, a movable cavity is formed in the disc body, a plurality of installation openings are formed in the inner side wall of the movable cavity, a plurality of clamping teeth are rotationally connected to the inner side wall of the movable cavity, and the clamping teeth penetrate through the installation openings and extend outwards; and an adjusting ring is rotatably connected to the inner side wall of the movable cavity, the clamping teeth are connected with the adjusting ring through a connecting mechanism, and an adjustingdevice matched with the adjusting ring is arranged on the front side of the disc body. The adjusting device is used for driving the adjusting ring to slightly rotate; the adjusting ring drives the clamping teeth to deflect through a rotating rod in the connecting mechanism; the clamping teeth deflect towards the inner side of the installation opening after deflecting, so that the outer diameter of the whole chain disc is reduced, the chain can be directly arranged on two chain discs in a sleeving mode, then arc-shaped blocks are rotated reversely to enable the clamping teeth to be inserted into the chain, the positions of the arc-shaped blocks are fixed through screws, and convenience is brought to chain mounting work.

Description

technical field [0001] The invention relates to the technical field of chain discs, in particular to a chain disc for bicycles which is easy to install. Background technique [0002] The chain is used in conjunction with the chain and is mostly used for mechanical transmission and traction. There are straight teeth arranged equidistantly on it. When in use, the transmission is realized through the meshing of the straight teeth and the chain. It is especially widely used in mechanical transmission. [0003] Among them, the chain used by the bicycle is easy to fall during the bicycle riding process, and after falling, the chain needs to be fixed on one of the chain discs first, and then it is stabilized by the rotation of the bicycle pedal, and then it is installed On the other chain disc, it brings inconvenience to the installation of the chain. At the same time, the existing chain disc chain needs to add lubricating oil during daily maintenance. At the same time, it is easy...
