Abstract
A bicycle convenient for folding comprises a bicycle frame, a front fork and a rear fork, wherein the bicycle frame comprises a frame horizontal tube, a stand pipe and a front fork tube; the frame horizontal tube comprises a front frame horizontal tube and a rear frame horizontal tube; the front frame horizontal tube is pivotally connected with a front hinge plate on the front fork tube; a rear hinge plate of the rear frame horizontal tube is pivotally connected with a stand pipe hinge plate of the stand pipe through a hinge shaft; the rear fork is pivotally connected with the hinge shaft, and the rear fork is fixedly connected with the stand pipe or is pivotally connected with the rear frame horizontal tube; the front frame horizontal tube is pivotally connected with the rear frame horizontal tube through a fixed shaft, the lower ends of two brackets are connected with the fixed shaft, and the upper ends of the two brackets are fixedly connected through a hand shaft; the front end of a front connecting rod is pivotally connected with the front hinge plate, and the rear end of the front connecting rod is pivotally connected with the hand shaft; and the front end of a rear connecting rod is pivotally connected with the hand shaft, and the rear end of the rear connecting rod is pivotally connected with the stand pipe. When the bicycle frame needs to be folded, a pin is separated from a hasp and the front frame horizontal tube, and the hand shaft is lifted upwards by hands, so that the folding can be achieved; and when the bicycle frame needs to be unfolded, the front fork tube and the stand pipe are held by hands and are stretched towards the two sides, and the bicycle can be used when the hasp and the front frame horizontal tube are fixed through the pin after being lapped. Therefore, the bicycle is convenient for folding and unfolding.

Perhaps captive joint with the rear end of side arm transverse tube respectively in the lower end of two supports;
Perhaps captive joint with the front end of after-frame transverse tube respectively in the lower end of two supports;
On the after-frame transverse tube hasp is arranged, the rear end overlap joint of hasp and side arm transverse tube, a pin cooperates with hasp, side arm transverse tube.
Described a kind of bicycle that makes things convenient for folding, its special character is: on the described standpipe support tube is arranged, the rear end of rear linking rod and support tube articulate.
Described a kind of bicycle that makes things convenient for folding, its special character is: side arm transverse tube lower end has certain axle bed, and dead axle is captiveed joint with the dead axle seat, and the lower end of hasp and dead axle articulate.
A kind of bicycle that makes things convenient for folding of the present invention owing to adopt such structure, when the needs folding bicycle frame, separates pin with hasp, side arm transverse tube, promptly can realize folding with handle axle on hand; When needs launch, hold front fork tube and standpipe, stretch to both sides, behind hasp and the side arm transverse tube overlap joint, promptly can use with pin is fixing.So folding, expansion are conveniently.
