Abstract

The invention discloses a self-locking folding bicycle, belonging to the field of bicycles. The self-locking folding bicycle comprises a handle bar, a front wheel, a rear wheel, a saddle, a crank chain wheel and a chain; a frame comprises a front tube, an upper hinge, a lower hinge, an upper tube, a saddle tube, a lower tube, a support fork, a reinforcing tube, a rear wheel fork, an upper shaft pin, a clamp pin and a lower shaft pin, wherein the front tube, the upper hinge and the lower hinge are integrally formed; the upper tube, the saddle tube and the clamp pin are integrally formed; the lower tube, the support fork, the reinforcing tube and the rear wheel fork are integrally formed; the upper hinge and the upper tube are rotatably connected through the upper shaft pin; the lower hinge and the lower tube are rotatably connected through the lower shaft pin; and the saddle tube and the support fork are connected through the clamp pin in a slot clamp support manner. In folding, the saddle tube is lifted upwards; and when the clamp pin leaves a slot at the upper end of the support fork, the handle bar, the upper tube, the saddle and the saddle tube are rotated counterclockwise together, thus the bicycle can be folded. The self-locking folding bicycle disclosed by the invention has the advantages that the folding time is short, the operation is very convenient, and the folding is more compact than that of the same type of folding bicycles.

Description

The self-locking folding bicycle

Affiliated technical field

The present invention relates to a kind of bicycle, especially a kind of self-locking folding bicycle.

Background technology

Present known folding bicycle generally all is provided with the part of industry slang for " quick detach ", and this is a kind of releasable part of locking; When folding bicycle need be ridden, the operation quick detach was with the turning joint locking of folding bicycle; When folding bicycle need fold, the operation quick detach unclamped the turning joint of folding bicycle.Known this folding bicycle, its weak point are that the folding time is longer relatively, and the folding bicycle that particularly has is provided with several quick detach, and the not only folding time is long, and inconvenient operation.

Summary of the invention

In order to overcome the deficiency of existing folding bicycle, the present invention provides a kind of self-locking folding bicycle, and the self-locking folding bicycle is not established quick detach, does not operate the action of quick detach when folding, and the not only folding time is short, and folding very convenient.

Technical scheme of the present invention is: the self-locking folding bicycle comprises handlebar, front-wheel, trailing wheel, saddle, crank and chain-wheel, chain; Vehicle frame by preceding pipe, go up hinge, down hinge, go up pipe, saddle pipe, down pipe, stay fork, reinforced pipe, rear wheel fork, go up pivot pin, bayonet lock, lower shaft pin and constitute; Pipe wherein, go up hinge, cut with scissors as a wholely down, last pipe, saddle pipe, bayonet lock are as a whole, and following pipe, stay fork, reinforced pipe, rear wheel fork are as a whole; Last hinge is connected with rotating mode with the last effective pivot pin of going up, and following hinge is connected with rotating mode with following effective lower shaft pin, and saddle pipe is connected with the mode of bayonet lock with the groove Kato with stay fork.

Function of the present invention is achieved in that owing to saddle, saddle pipe, upward the deadweight of pipe is a pressed downward, and the bayonet lock that is fixed on the saddle pipe is pressed in the groove of stay fork upper end, and vehicle frame is self-locking; Last pivot pin, bayonet lock, lower shaft pin are leg-of-mutton 3 points, and stability is leg-of-mutton characteristic, so vehicle frame of the present invention is stable.When folding, up carry saddle pipe, when bayonet lock leaves the groove of stay fork upper end, with handlebar, go up pipe, saddle, the counter-clockwise together rotation of saddle pipe can be good with bicycle folding.

The invention has the beneficial effects as follows:

(1) not only folding time weak point, and easy to operate.

(2) more compactly more folding than similar folding bicycle.

Description of drawings

Fig. 1 is the scheme drawing of riding condition of the present invention.

Fig. 2 is the scheme drawing of folded state of the present invention.

Among the figure: pipe on 1 saddle, 2 saddle pipes, 3, pipes before the hinge, 7 on the pivot pin, 6 on 4 handlebars, 5,8 front-wheels, 9 times hinges, 10 lower shaft pins, 11 times pipes, 12 crank and chain-wheels, 13 rear wheel fork, 14 chains, 15 trailing wheels, 16 reinforced pipes, 17 stay forks, 18 bayonet locks.

The specific embodiment

Like Fig. 1, shown in Figure 2: the present invention includes handlebar 4, front-wheel 8, trailing wheel 15, saddle 1, crank and chain-wheel 12, chain 14; Vehicle frame by preceding pipe 7, on cut with scissors 6, cut with scissors 9 down, on manage 3, saddle pipe 2, manage 11 down, stay fork 17, reinforced pipe 16, rear wheel fork 13, go up pivot pin 5, bayonet lock 18, lower shaft pin 10 and constitute; Pipe 7 wherein, on cut with scissors 6, cut with scissors down 9 as a whole; Last pipe 3, saddle pipe 2, bayonet lock 18 are as a whole; Under manage 11, stay fork 17, reinforced pipe 16, rear wheel fork 13 be as a whole; Last hinge 6 is used pivot pin 5 with last pipe 3 and is connected with rotating mode, and following hinge 9 is connected with rotating mode with following pipe 11 usefulness lower shaft pins 10, and saddle pipe 2 is connected with the mode of stay fork 17 usefulness bayonet locks 18 with the groove Kato.

Function of the present invention is achieved in that because saddle 1, saddle pipe 2, on to manage 3 deadweight be pressed downward, the bayonet lock 18 that is fixed on the saddle pipe 2 is pressed in the groove of stay fork 17 upper ends, vehicle frame is self-locking; Last pivot pin 5, bayonet lock 18, lower shaft pin 10 are leg-of-mutton 3 points, and stability is leg-of-mutton characteristic, so vehicle frame of the present invention is stable.Up carry saddle pipe 2 when folding, when bayonet lock 18 leaves the groove of stay fork 17 upper ends, with handlebar 4, on manage 3, saddle 1, the counter-clockwise together rotation of saddle pipe 2 can be folded into Fig. 2 state.
