Abstract

A tail cover hinge-type connected bicycle chain cover relates to a bicycle chain cover, which includes a tail cover, a cover body and a round cap, and has main technical characteristics the tail cover and the cover body are in hinge-type connection, that is, two iron hinges are respectively fixed on the edges of the chain cover. The invention connects the tail and the cover body cutting-off point by using a butterfly type hinge, which resolves the conjunction degree of the tail and the cover body; and resolves the problem that the phosphating and spray painting are not in place. Simultaneously the assembly time is greatly quickened, and the quality is greatly improved.

Description

Technical field: [0001] The invention relates to a bicycle chain cover. Background technique: [0002] The chain cover is composed of a tail, a cover body and a round cover, but the tail is cut directly from the back of the cover, so the traditional chain cover tail and the cover body are connected by upper and lower tabs. The top is fixed with screws. This structure caused a lot of trouble for the customer, because the chain cover required pre-treatment and spray-painting processes. If the screws were not unscrewed, the joint between the tail and the cover body would not be able to be processed and spray-painted, and it would rust after a long time. If the screw is unscrewed, the tail and the hood are easy to be mistaken, resulting in poor fit, and a large amount of work is required. Therefore, the tail and the hood must be marked, and the phosphating and painting must be done twice. Invention content: [0003] The invention provides a bicycle chain cover which connects...
