Description

Collapsible bicycle

The utility model relates to a kind of Collapsible bicycle.

China is bikedom, and bicycle is the main vehicle of present China wage-earners.Comparatively generally common men's clothing, women's dress bicycle and the mountain bike of domestic use.Along with urban traffic environment and live the improvement of environment, as opening of special line bus, subway and building up of high-rise residential building, people wish that bicycle is in light weight, volume is little, be convenient for carrying, the vehicle such as bus, subway, elevator on when short distance traffic, being with, thus realize theft-proof purpose.But present various bicycles all can not satisfy above-mentioned requirement.

The purpose of this utility model just is to overcome the shortcoming that present bicycle is inconvenient to carry, provide a kind of in light weight, collapsible, volume after folding is little, the bicycle that is convenient for carrying.

The utility model is to realize like this.Standard is all adopted in its front and back wheel and drive mechanism, brake etc.Adopt the women's dress main car frame, at women's dress main car frame middle part foldable structure is arranged, a side of foldable structure adopts the upper and lower riveted binding site of rivet, and opposite side adopts screw to twist up and down and closes or adopt the engaging of spring clamping close device.

Respectively there is an auxiliary wheel corresponding position before and after the main car frame folding part.

Can have semiclosed guard shield (mudwing) to cover front and back wheel, there is elastic at the middle part of guard shield, fastens for folding back and uses.

The L type handgrip of button was riveting in the two ends, the left and right sides of the tabula of lower end in handgrip of the present utility model adopted two, and there is a disk knob handgrip middle and lower part, by connecting handgrip about screw, screw knob, left and right handles is with receiving with putting the interior time receiving, two L type handles are close together, and are convenient to push-and-pull.When putting outward, use when being convenient to by bike.The middle and lower part of tabula and two handgrips has a can to encase, but under stay drain gutter, the disc knob position is stayed in the middle and lower part.

Tabula and can are connected by transverse axis or other rotatable structure with main car frame, also there is the handle of a band latch main car frame front upper part handle structure below, its latch is stuck in the tapping of the midway location of tabula and can, the midway location and the rear lower perforate of tabula and outer can thereof snap in for latch.The tabula structure is rotary folding backward, and the handle of latch is with in folding back, is sticked in the rear lower perforate of tabula and can.

Saddle of the present utility model can adopt level to regulate height.By be fixed on the guard shield under the saddle or the chassis of guard shield top on the two relative latches of pincerlike structure, insert in cooresponding number two relative knock holees of row on the saddle pillar and obtain the location, and by the pincerlike structure latch of folding, the knock hole that makes it to insert in differing heights is regulated height.

The utlity model has collapsiblely, volume after folding is little, is portability by dilatory Handlebar of bicycle, and the vehicle such as bus, subway, elevator on the portability are specially adapted to city wage-earners and traveller and use.

Below in conjunction with drawings and Examples the utility model is done an into explanation.
