Abstract

The utility model relates to a folding bicycle which comprises a bicycle frame, a front wheel, a back wheel and a saddle, wherein the bicycle frame comprises a front fork, a front vertical pipe which can be rotationally sheathed on the front fork, a handlebar and a back fork. The front wheel is arranged on the lower part of the front fork, and the back wheel is arranged on the lower part of the back fork. When the folding bicycle is unfolded, the handlebar and the front fork are connected into integration. The front vertical pipe backward extends to form the backward extending section of the front vertical pipe, the upper end part of the back fork is rotationally connected with the backward extending section of the front vertical pipe and the saddle is arranged on the backward extending section of the front vertical pipe. When the folding bicycle is required to be folded, only the back end part of the backward extending section of the front vertical pipe is required to be upward lifted, the back fork uses the rotating axle center of the back fork and the backward extending section of the front vertical pipe as the circle center to clockwise and downward rotate and then the folding bicycle can be folded. The utility model can be simply and rapidly folded.

Description

A kind of Foldable bicycle

Technical field

The utility model relates to a kind of Foldable bicycle.

Background technology

For moving in incity, city young people, folding bicycle then is as the hold concurrently optimal selection of outdoor leisure activity of the vehicle, such as, more and more Duo youngster is riding folding bicycle and is travelling to and fro between family-subway station-company, this shows, requirement for folding bicycle is folding quick, simple in structure, and generally all there is folding long defective of loaded down with trivial details, folding time in folding bicycle of the prior art.

Summary of the invention

The utility model purpose provides a kind of Foldable bicycle, and it is folding simple, quick.

For achieving the above object, the technical solution adopted in the utility model is: a kind of Foldable bicycle, comprise bicycle rack, front-wheel, trailing wheel, saddle, described bicycle rack comprises front fork, be set in the preceding standpipe on the described front fork rotationally, handlebar, back vent, described front-wheel is arranged at the bottom of described front fork, described trailing wheel is arranged at the bottom of described back vent, when Foldable bicycle launches, described handlebar and described front fork link into an integrated entity, extension behind the standpipe before standpipe extends back and forms before described, the upper end of described back vent with described before behind the standpipe extension rotate and be connected, described saddle is arranged at behind the described preceding standpipe on the extension.

Because technique scheme utilization, the utility model compared with prior art has following advantage: because the extension is connected rotatedly behind described back vent and the described preceding standpipe, when needs are folding with Foldable bicycle, only need the rearward end of extension behind the standpipe before described is upwards lifted, described back vent is that center of circle cw rotates with the center of rotation of extension behind described back vent and the preceding standpipe just, this moment, described Foldable bicycle just can fold, and it is folding simple, quick.

The specific embodiment

As shown in Figure 1, a kind of Foldable bicycle comprises bicycle rack 1, front-wheel 2, trailing wheel 3, saddle 4.

Described bicycle rack 1 comprises front fork 5, is set in preceding standpipe 8, handlebar 7, back vent 6 on the described front fork 5 rotationally, described front-wheel 2 is arranged at the bottom of described front fork 5, described trailing wheel 3 is arranged at the bottom of described back vent 6, when Foldable bicycle launched, described handlebar 7 linked into an integrated entity with described front fork 5.Described handlebar 7 can be to be fixedly connected with described front fork 5; Described handlebar 7 also can be to rotate to be connected with described front fork 5, when Foldable bicycle is folding, does not have diagram, and the described relatively front fork 5 of described handlebar 7 folds.

Shown in accompanying drawing 1, accompanying drawing 2, extension 9 behind the standpipe before standpipe 8 extends back and forms before described, the upper end of described back vent 6 with described before behind the standpipe extension 9 rotate and be connected, the rear portion of extension 9 rotates and is connected behind the upper end of described back vent 6 and the described preceding standpipe.Described saddle 4 be arranged at described before behind the standpipe on the extension 9.Described saddle 4 be arranged at described before the rearward end of extension 9 behind the standpipe.

Extension 9 is provided with position locking mechanism 10 with the place of being rotationally connected of described back vent 6 behind the described preceding standpipe.As shown in Figure 1, described position locking mechanism 10 is locked in deployed condition with described a kind of Foldable bicycle.Such as, described position locking mechanism 10 can be to have lock slots in 6 two of extension 9 and the described back vents behind the standpipe before described, be provided with latch hook on another rotationally, when Foldable bicycle launched, described latch hook hooked described lock slots.

Extension 9 is provided with locating part 11 behind the described preceding standpipe, when Foldable bicycle launches, described back vent 6 is against on the described locating part 11, and the described back vent 6 of described locating part 11 restrictions is that center of circle conter clockwise continues upwards to rotate with the center of rotation of extension 9 behind described back vent 6 and the preceding standpipe.
