Abstract

The invention discloses a lubricating shell for a bicycle chain. The lubricating shell comprises a shell body, a first fixing base, a second fixing base, a spring, a first gear, a screw, a connecting rod, a second gear and an oil box device. The first fixing base is arranged on the inner side of the lower end of the shell body and provided with the screw. The spring is arranged on the outer side of the screw. The first gear is arranged at the top end of the screw and engaged with the chain. The second fixing base is arranged on the inner side of the top end of the shell body. The connecting rod is arranged at the lower end of the second fixing base. The second gear is arranged at the lower end of the connecting rod. The connecting rod is provided with the oil box device, and the second gear makes contact with the oil box device. The lubricating shell for the bicycle chain is simple in structure and convenient to use, disengagement of the chain is avoided, self lubrication is achieved, and time, effort and materials are saved.

Description

technical field [0001] The invention relates to the technical field of bicycles, in particular to a bicycle chain lubricating shell. Background technique [0002] Bicycles, also known as bicycles or bicycles, were introduced into China from Western countries, usually small land vehicles with two wheels. Bicycles are all over the world now, entering every household, and are the most common means of transportation for people. After a person rides on the car, it is powered by pedals, which is a green and environmentally friendly means of transportation. [0003] In the semi-closed state of the outer casing of the existing bicycle chain, the chain is wrapped inside the casing body, and the rotation of the flywheel is driven by the chain, thereby driving the walking of the wheel. However, the existing chains often cause problems such as rusting during long-term use and rain erosion. The lighter ones will make weird noises due to rusting, and the heavier ones will directly break...
