Abstract

The utility model particularly relates to a portable bicycle with small wheels, which can be folded into a small portable bicycle and carried out conveniently. A comma-shaped wafer is respectively arranged on a left handle and a right handle, and the comma-shaped wafer is clamped in a horseshoe-shaped clamping sheet on the top end of a direction rod. Through a bolt knob the comma-shaped wafer is locked or unlocked to make the left handle, the right handle and the direction rod folded; the direction rod, a direction folding frame and a front fork can be folded in the shaped of Z; a seat rod, a folding frame of a seat and a bicycle body can be folded in the shaped of Z; the direction folding frame and the folding frame of the seat are both made of groove-shaped and pipe-shaped materials; after folded, the two section materials are in the shape of inlay. The bicycle body is in the shape of Y, a folding hinge which can be folded is arranged in the middle of the bicycle body, therefore the portable bicycle can be folded as small as possible.

Description

Portable bicycle

Technical field: the utility model relates to a kind of bicycle, particularly a kind of trundle, portable bicycle collapsible, more convenient to carry.

Background technology: existing frame is relatively large, and inconvenience is carried, and bicycle and bus, subway and other modes of transport organically can not be combined use.Though existing multiple Folding Bicycle on the market, but bicycle folding can't be got very little, even little to the bicycle that can be placed in the knapsack.

Summary of the invention:

The purpose of this utility model is to provide a kind of steamboat, collapsible very for a short time, more portable portable bicycle.

The purpose of this utility model realizes like this: portable bicycle comprises vehicle body, vehicle body folded chain, steering handle, direction lever, direction folding stand, front fork, direction seat, steering wheel, vehicle seat, seat post, seat folding stand, axis, countershaft, sprocket wheel, chain, step, flywheel, trailing wheel.It is characterized in that the left and right directions handgrip respectively is with a comma shape disk, respectively be with two little gap on the disk; Two spring pins are arranged before and after the direction lever top, and the intermediate plate of two horse-hof shapes before and after having, the comma shape disk of left and right directions handgrip is sandwiched wherein, can or unclamp its locking by the bolt button, thereby make between left and right directions handle and the direction lever collapsible.The other end of direction lever has an ear shape connecting strap, on two holes are arranged, be connected with the direction folding stand with bolt by riveting pin; The direction folding stand has a grooved and a tube type material to constitute, and connects front fork and direction lever by riveting pin etc., makes direction lever, direction folding stand, and it is folding to make the Z font between this three of front fork; During expansion, the direction folding stand is triangular in shape, and as will fold the time, the button that only need looser a bolt presses down direction lever forward then and get final product, and a grooved and a tube type material of direction folding stand are zyklopisch at this moment.The other end of seat post also has an ear shape connecting strap, on two holes are arranged, be connected with the seat folding stand with bolt by riveting pin, the seat folding stand also has a grooved and a tube type material to constitute, by connection vehicle body and seat post such as riveting pins, make that can make zigzag between seat post, seat folding stand, this three of vehicle body folds; During expansion, the seat post folding stand is triangular form, as will fold the time, as long as looser a bolt button, the related seat post of vehicle seat is pressed down forward get final product then, and this moment, one grooved and a tube type material of seat folding stand were zyklopisch.Vehicle body is chevron pointing, and there is folded chain the centre, but doubling.The top of vehicle body is located by axis and countershaft are housed by the back slightly, axis is fixed with hinge wheel and step, countershaft is fixed with small one and large one two sprocket wheels, the hinge wheel of axis the minor sprocket of countershaft by the chain band, the hinge wheel of countershaft flywheel on the trailing wheel by the chain band, thereby formed the secondary speedup of this car, guaranteed the speed of the quite common wheel bicycle of BMX (Bicycle Motocross) speed.

The beneficial effect that the utility model has really is; Owing to adopted left and right directions collapsible, it is folding to make zigzag between direction lever, direction folding stand, this three of front fork, it is folding to make zigzag between seat post, seat folding stand, this three of vehicle body, but doubling in the middle of the chevron pointing vehicle body, make this car collapsible very for a short time, in addition little of putting into knapsack.

Among the figure: 1-vehicle body, 2-vehicle body folded chain, 3-steering handle, 4-direction lever, 5-direction folding stand, 6-front fork, 7-direction seat, 8-steering wheel, 9-vehicle seat; The 10-seat post, 11-seat folding stand, 12-axis, 13-countershaft, 14-step, 15-trailing wheel, 16-bolt button.

The utility model is described in further detail below in conjunction with accompanying drawing

The specific embodiment:

Embodiment: according to Fig. 1, portable bicycle comprises vehicle body 1, vehicle body folded chain 2, steering handle 3, direction lever 4, direction folding stand 5, front fork 6, direction seat 7, steering wheel 8, vehicle seat 9, seat post 10, seat folding stand 11, axis 12, countershaft 13, step 14, trailing wheel 15, bolt button 16.With reference to Fig. 2,3, two spring pins are arranged before and after direction lever 4 tops, and the intermediate plate of two horse-hof shapes before and after having, two comma shape disks of left and right directions handgrip 3 are sandwiched wherein, can or unclamp its locking by turning bolt button 16, thereby make between left and right directions handgrip 3 and the direction lever 4 collapsible.With reference to Fig. 1,4,5, the other end of direction lever 4 has an ear shape connecting strap, is connected with direction folding stand 5 with bolt button 16 by riveting pin; Direction folding stand 5 has a channel material to constitute, and by connection front fork 6 and direction levers 4 such as riveting pins, makes that can make zigzag between direction lever 4, direction folding stand 5, front fork 6 these threes folds; During expansion, direction folding stand 5 is triangular in shape, as will draw in the time, as long as looser a bolt button 16, direction lever 4 is pressed down forward get final product then, and this moment, direction folding stand 5 grooved and tube type material was zyklopisch.The other end of seat post 10 also has an ear shape connecting strap, be connected with seat folding stand 11 with bolt button 16 by riveting pin, seat folding stand 11 also has a grooved and a tube type material to constitute, by connection vehicle body 1 and seat post 10 such as riveting pins, make that can make zigzag between seat post 10, seat folding stand 11, vehicle body 1 this three folds; During expansion, seat folding stand 11 is triangular in shape, and as will draw in the time, the button 16 that loosers a bolt presses down vehicle seat 9 related seat post 10 forward then and gets final product, and this moment, seat folding stand 11 grooved and tube type material was zyklopisch.Vehicle body 1 is chevron pointing, and there is folded chain 2 centre, but doubling.With reference to Fig. 1, the top of vehicle body 1 is located by axis 12 and countershaft 13 are housed by the back slightly, and axis 12 is fixed with hinge wheel and step 14, and countershaft 13 is fixed with hinge wheel and minor sprocket.When riding, step on step 14, make axis 12 rotate, hinge wheel on the axis 12 makes countershaft 13 rotate, and forms acceleration by the minor sprocket on the chain drive countershaft 13, hinge wheel on the countershaft 13 is again by the flywheel on the chain drive trailing wheel 15, make trailing wheel 15 rotate, and form acceleration again, thereby guarantee that this portable bicycle wheel is little and effect that the speed of a motor vehicle is not slow.
