Abstract

The invention discloses an easy-to-install chain disk for bicycles, which comprises a disk body, an activity chamber is opened inside the disk body, a plurality of installation openings are opened on the inner wall of the activity chamber, and the inner wall of the activity chamber is rotatably connected with A plurality of latches, a plurality of latches all pass through the installation port and extend outward; the inner wall of the movable chamber is rotatably connected to an adjustment ring, and the latches are connected to the adjustment ring through a connecting mechanism, and the front side of the disc body An adjustment device matching the adjustment ring is provided. The invention uses the adjustment device to drive the adjustment ring to rotate slightly, and the adjustment ring drives the locking teeth to deflect through the rotating rod in the connecting mechanism, and the locking teeth deflect to the inside of the installation port after deflection, so that the overall outer diameter of the chain plate is reduced, and the chain can be directly sleeved On the two chain discs, reversely rotate the arc-shaped block so that the teeth are inserted into the chain and then fix the position of the arc-shaped block with screws, which brings convenience to the installation work of the chain.

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 plate 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 i...
