Abstract
The utility model provides a bicycle folding mechanism and a folding bicycle. The folding bicycle comprises a rear wheel support, a saddle support, a front wheel support, a handle support and the folding mechanism. The folding mechanism comprises a fixing device, a central supporting shaft and a shell body. The fixing device comprises clamping teeth and a clamping tooth supporting body connected with the clamping teeth in an abutting mode. A clamping groove is formed in the central supporting shaft. The clamping teeth can move in a reciprocating mode in the clamping groove. An opening is formed in the lower portion of the clamping groove to accommodate the clamping tooth supporting body. The other end of the clamping tooth supporting body is connected with a groove formed in the shell body in an abutting mode. The groove is provided with an inclined bottom surface. A first through hole and a second through hole are formed in the side face of the shell body. One end of the rear wheel support and one end of the saddle support are installed on the central supporting shaft. The other end of the rear wheel support and the other end of the saddle support are guided out through the first through hole and can rotate around the central supporting shaft in the first through hole. One end of the front wheel support and one end of the handle support are installed on the central supporting shaft. The other end of the front wheel support and the other end of the handle support are guided out through the second through hole and can rotate around the central supporting shaft in the second through hole. The shell body is rotated so as to control the clamping tooth supporting body to drive the clamping teeth to move in the reciprocating mode, and therefore the locking and unlocking between all the supports and the central supporting shaft are controlled.
