Abstract

The utility model provides an improved foldable bicycle which comprises a handlebar, a front wheel, a rear wheel, a foldable frame, a chain disc mechanism and a goods bracket and is characterized in that the chain disc mechanism can rotate up and down taking a rear axle or a driving wheel of the rear axle as the center of a circle and has the beneficial effects that the chain disc mechanism is connected with the goods bracket by a pull rod; when the bicycle is folded, the goods bracket is pulled out and lifted, the tail end of the goods bracket is fixed on a hook of the handlebar, the chain disc mechanism moves upwards and retracts below a seat and between the two wheels, and a hook on the pull rod is fixed on a hanging nail on the frame, so that the width of the folded bicycle is only the same as the width of a wheel, the two wheels are kept concentric so as to facilitate to push the bicycle forward, and the improved foldable bicycle appears to be dexterous and does not occupy a position.

Description

A kind of improved folding bicycle

Technical field

The utility model relates to a kind of improved folding bicycle.

Background technology

Existing folding bicycle, its chain disc mechanism of folding back has half the horizontal the place ahead between two-wheeled, can't shrink and put in place, and it is agile inadequately that such folding bicycle seems, occupies.

Summary of the invention

The purpose of the utility model is that a kind of improved folding bicycle will be provided, and when folding, lets move on the chain disc mechanism, contracts below the seat and between the two-wheeled, and it is wide to make the width of the bicycle after folding only take turns, and two-wheeled keeps making things convenient for go-cart to move ahead with one heart.

The utility model is to realize like this; Said a kind of improved folding bicycle; It comprises handlebar, front-wheel, trailing wheel, folding vehicle frame, chain disc mechanism, shelf, it is characterized in that: said chain disc mechanism can be that rotate up and down in the center of circle with the power wheel of rear axle or rear axle.

The axis top of the said chain disc mechanism of the utility model is provided with hinge; Hinge is connected with an end of pull bar; One side of the other end of pull bar and shelf front end is rotationally connected; The front end of shelf is stuck in the under-seat of vehicle frame back segment, and shelf can be pulled out the top of mentioning and lifting chain disc mechanism to trailing wheel through pull bar.The upper end of said pull bar is provided with hook, and a side of frame end is provided with clothes-hook, and after the chain disc mechanism was put to the top of trailing wheel, the hook on the pull bar was fixed on the clothes-hook of vehicle frame.Handlebar is provided with hook, and the shelf end of pull-up is fixed on the hook of handlebar.

Said chain disc mechanism comprises gear, chain or synchronous band, crank, foot-operated.

The beneficial effect of the utility model is, the chain disc mechanism is connected with shelf through pull bar, when bicycle folding, pulls out and mentions shelf; The shelf end is fixed on the hook of handlebar, move on the chain disc mechanism this moment, contracts below the seat and between the two-wheeled; Hook on the pull bar is fixed on the clothes-hook of vehicle frame, and the width of the bicycle after feasible the folding is only taken turns wide, and two-wheeled keeps with one heart; Make things convenient for go-cart to move ahead, such folding bicycle seems agilely, does not occupy.
