Abstract
The utility model relates to a portable folding variable speed bicycle which is provided with two interfaces 2 and 3 which can be quickly assembled or detached and a non-positioning interface 6 with a buffer, and the whole bicycle is divided into a front wheel, a back wheel, a bicycle body and a spigot at the front of the bicycle. The interfaces adopts a folding method which can enables the four part of the whole bicycle to fold skillfully in a very narrow space; the folding is following the processes 1, 2 and 3 in order, and the folding bicycle is shortened and fastened by a seat rod making use of the wrench mechanism 4 of an eccentric shaft. The folding parts are assembled into integration which can not loose by an eccentric thrust roller 5.
Description
The utility model relates to a kind of portable folding variable speed bicycle.
The overwhelming majority of existing bicycle trade production is non-Folding Bicycle, all exists to place to move difficulty, easily causes accident stolen, that decreased.It is also big to take parking space.Especially the people that needs are changed to the different vehicle is inconvenient especially.Can't reach the purpose that takes a bus instead of walking.And existing folded bicycle still dislikes compact inadequately after folding.And the folding weak point of trouble of opening of existence.
The purpose of this utility model is to overcome the weak point that has bicycle now and the portable folding variable speed bicycle that designs a kind of compactness.
The purpose of this utility model realizes by following design, and bicycle is provided with trailing wheel and gets rid of folding frame mechanism (1) central sill fold mechanism (2) tap and be folded down contract eccentric shaft spanner mechanism (4) down of mechanism (3) seat rod and be provided with adjustable eccentric gear wheel (a 5) trailing wheel get rid of a jiao of folding frame mechanism and establish a rubber column (6) and connect to realize cushioning with the on-fixed of vehicle body on the catch mud of back.
Advantage of the present utility model: because trailing wheel has taked to get rid of folded structure design, folding back two-wheeled all is in the central sill below and forms very compact integral body, carry deposit very convenient.
Description of drawings:

Fig. 7 is the utility model chain tensioner sprocket figure
Fig. 7 A is the utility model chain tensioner sprocket birds-eye view
Fig. 8 is pedaled figure for the utility model left foot
Accompanying drawing has been represented structure of the present utility model, in conjunction with the embodiments formation of the present utility model and principle is further elaborated below again.The utility model can be divided into five major parts: comprise that triangle gets rid of the trailing wheel of folding frame; Front-wheel; The first tap of car; The vehicle body central sill; And seat cushion and seat cushion bar.When trailing wheel being got rid of when folding to become to park state under the vehicle body central sill.Because chain tensioner sprocket arm 72 relies on the elasticity backswing of torsion springs, chain still can be held in 71 and each sprocket wheel on.The inner drawing type change-speed box at trailing wheel center also can not change because of folding.See Fig. 3, after central sill is folding, trailing wheel and middle beam spacing are further dwindled, the front-wheel front fork hangs on the trailing wheel spider, the structure of interface 2,3 is seen Fig. 6, main flange 61 and the flange 62 of turning back are designed to wedge shape with compact heap 64 places of matching, just can be firm and promptly close or open folding mouth under the effect of handle screw 63.The first tap of car is folded down by last front fork.Pull the eccentric shaft spanner 4 under the vehicle seat, can unclamp or tighten up the Hough bell and spigot of seat rod easily.And after seat rod contracted down, the position of adjustable eccentric gear wheel 5 can not got rid of back trailing wheel when mentioning car.The elasticity at last left foot among Fig. 8 pedaled pendulum plate 84 is released, and makes it to slip over the edge mouth of pedal flange 82, whole pedal frame 81 around the pedal flange flip to the outside 90 ° with same plane, pedal rod place.Rely on the effect of spring 83 when opening, elasticity pendulum plate goes back on the seam that original position terminates in the pedal flange at an easy rate.So far a whole car has just become the folded formation of a compactness, is convenient to that the user deposits or moves.
