Abstract

The invention provides a bicycle rear derailleur comprising a frame, a fixing plate, a speed changing gear, a cleaning brush structure, an anti-stripping reinforcing ring structure, a lubricating oilkettle device, a tension spring, a connecting handle, an anti-stripping spring, a tension gear, a limiting hook, a chain gear, a chain plate, a connecting plate and a rain-proof shell. The arrangementof the brush and the steel wire brush is favorable for cleaning the oil dirt or the dust on the derailleur, and solves the problem of lacking the cleaning function; the clasp is arranged so as to prevent the fixing plate from slipping or losing due to loosening, and solve the problem that the fixing bolt of the derailleur is loosened or slipped easily due to frequent speed change, thereby causingthe derailleur to lose; an oil kettle is favorable for oiling and lubricating the tensioning gear and the chain pulling gear, and solves the problem that lubricating oil cannot be filled for the derailleur, and improves the usability of the rear chain pulling device of the bicycle.

Description

technical field [0001] The invention belongs to the technical field of bicycle accessories, in particular to a bicycle rear derailleur. Background technique [0002] With the improvement of people's living standards, people's awareness of fitness is also increasing, but people often encounter various problems when using variable speed bicycles, such as: the derailleur does not change smoothly due to insufficient lubrication, Or various situations occur because maintenance is not in place, if purchasing maintenance equipment separately will undoubtedly increase the extra expenses of bicycle users, increase the economic burden. [0003] The Chinese patent publication number is CN2252764, and the name of the invention is a bicycle rear derailleur, which includes the lower part of the mounting plate and the movable riveting of the support A, and the inner and outer connecting plates extending parallel to each other and pivotally connected to the front of the support A. The supp...
