Abstract

The invention discloses a rapid folding mechanism of a bicycle. The rapid folding mechanism of the bicycle comprises a bicycle rear frame, a movable steel tube and a pressing head; an upper rotating sleeve is fixed on one side of the bicycle rear frame; a lower rotating sleeve is fixedly connected to the upper rotating sleeve through the movable steel tube; a movable column is arranged at the center of the movable steel tube; a return spring is mounted on the external surface wall of the movable column; a backing plate is connected to one side of the movable column in a sleeving manner; a rubber sleeve is welded on one side of the backing plate; the pressing head is mounted on the other side of the rubber sleeve; a rotating shaft is arranged at the center of the pressing head; an anti-skidhole is formed in the external surface wall of the pressing head; a locking buckle is mounted above a fixing arc plate; and a fixing plate is arranged on one side of the locking buckle. According tothe rapid folding mechanism of the bicycle, the folding mechanism is compactly structured and convenient to use; and moreover, as the return spring, the backing plate and the rubber sleeve are arranged on equipment, the return spring guarantees the safety of the connection, and the backing plate and the rubber sleeve guarantee the stability of the mechanism during using.

Description

technical field [0001] The invention relates to the technical field of folding mechanism equipment, in particular to a quick folding mechanism of a bicycle. Background technique [0002] With the continuous development of society and the continuous progress of science and technology, it has created convenient conditions for people's lives, but it has also caused harm to the environment. effect, and the most important thing in low-carbon life is low-carbon travel. Our country vigorously advocates low-carbon travel, such as taking a bus and riding a bicycle. Therefore, bicycles have become a travel tool for some people, and folding bicycles can be manually moved Fold or unfold, easy to carry, convenient and comfortable to use. [0003] However, the folding mechanism of the existing folding bicycle has some disadvantages during use. The structure of the folding mechanism is not compact, the poor manufacturing material is easy to deform or even break, and the folding mechanism ...
