The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1, this folding bicycle comprises handlebar 14, vertical 16, front fork 12, vehicle frame, front-wheel 19 and trailing wheel 2, vehicle frame comprises that front end establishes the seat pipe 5 that sleeved saddle pipe 10 and top are provided with vehicle seat, and the rotating shaft at front fork 12 tops is positioned at sleeve, standing 16 bottom and the top of rotating shaft, joins.Front-wheel 19 is installed on front fork 12.
Vehicle frame also comprises the rear wheel frame consisting of chain stay 7, vertical fork and brace, and the top of brace is affixed with the top of vertical fork, and trailing wheel 2 is installed on rear wheel frame.In axis axle sleeve, be provided with the axis of pedal, sprocket wheel is set on axis, between sprocket wheel and rear axle, chain is set.
Between handle vertical 16 and rotating shaft, be provided with the first folder 17, on saddle pipe 10, be provided with the second folder 11.
The bottom of present pipe 5 is provided with the connector 9 with axis axle sleeve, in the both sides of this connector 9, is equipped with the connecting panel hinged with it 8.The inner of chain stay 7 and the bottom of brace are all fixed in connecting panel 8.On present pipe 5, be also provided with the blocking device 6 that the top of rear wheel frame is fixed.
Fig. 2 is the folded state diagram of this folding bicycle first step.Can find out: unclamp after the first folder 17, handlebar 14 is together with folding downwards vertical 16, until handlebar 14 is closely attached on front-wheel 19.In order to make handlebar 14 be unlikely to loosening in follow-up folding process, rock, in this example, also comprise the handlebar of doubling poststack 14 is entered to line-locked fastening firm organization.
Fig. 3 has shown the structural representation that fastens firm organization.Can find out: this mechanism comprise be located at the plug 15 on vertical 16 outer walls and be installed on sleeve outer wall, after handlebar 14 is folding the position fixture blocks 18 corresponding with plug 15.Wherein, plug 15 has circular or oval-shaped front end, has corresponding draw-in groove on fixture block 18, and plug 15 extruding fixture blocks 18 pierce in draw-in groove.
Fig. 4 is the folded state diagram of this folding bicycle second step.Can find out: unclamp the second folder 11, stir front-wheel 19 to side, front-wheel 19 is closely attached on saddle pipe 10 after rotating 180 °.
Fig. 5 is that the folded state diagram of this folding bicycle the 3rd step is also final condition figure.Can find out: unclamp after blocking device 6, clickwise rear wheel frame and trailing wheel 2, make it move to the place ahead of seat pipe 5 and be adjacent to side by side with front-wheel 19.In folding process, the position of seat pipe is almost unchanged.In this example, blocking device 6 comprises that being fixed in seat manages 5 snap close and the locking bar that is fixed in rear wheel frame top, is also provided with Jiao Dun on locking bar.Locking process is: rear wheel frame and trailing wheel 2 rotate counterclockwise until locking bar falls into realization locking in snap close.The effect of Jiao Dun is to prevent the impact of rear wheel frame to seat pipe 5, plays certain cushioning effect simultaneously in the process of riding.
In order to prevent producing and become flexible in the handling process after the degree of depth is folding, in this example, also comprise the buckle lock structure that the front-wheel 19 after folding and rear wheel frame are locked together.Refer to Fig. 6, this buckle lock structure comprises that being fixed in front fork gears 12 bottoms, L shaped pitches 13.The inner side that is inserted into chain stay 7 at the folding behind stopping fork 13 of the degree of depth, has prevented horizontal disengagement effectively.
