The portable folding bicycle is characterized in that an X-shaped crossed component is arranged between the frame front pipe and the frame rear pipe, the X-shaped intersected component, the frame front pipe and the frame rear pipe form a bicycle frame, wherein outer pipes of the X-shaped component are flat pipes comprising a left pipe and a right pipe, a circular inner tube is clamped between the two pipes and hinged in the middle, two ends of the inner pipe are respectively movably connected with hinges fixed on the frame front pipe and the frame rear pipe, each outer pipe is a flat pipe consisting of a front section and a rear section which are hinged, the end of the front section is movably connected with a hinge fixed on the frame front pipe while the end of the rear section is connected to the rear wheel which is arranged between the end of the rear sections of the two outer pipes, the handlebar is connected above the frame while a front fork is connected below the frame, the front wheel is fixed in the middle of the front fork, the saddle is fixed on the saddle pipe which is inserted on the frame rear pipe, and the frame rear pipe is inserted into a supporting disc fixed between the two outer pipes. The portable folding bicycle has the advantages of simple structure, convenient and fast folding operation and convenient carrying.

Description

Portable folding bicycle

Technical field

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

Background technology

At present, on the market mainly based on stationary bicycle.Along with flourish with tourist industry of improving constantly of people's living standard, portable folding bicycle appears in people's the visual field more and more, becomes people and travels frequently and ride instead of walk or leisure holiday or the new vehicle of outing campaign.Existing folding bicycle mostly exists the folding back of gathering thickness big, deposit common faults such as volume is bigger and can not satisfy the requirement that people are convenient for carrying, make bicycle when the entire package case, take unnecessary space, folding is put seemed helpless even influence popularizing of Collapsible bicycle.

The utility model content

The purpose of this utility model is to provide a kind of portable folding bicycle of new construction, can make the bicycle volume after folding very little, reaches the requirement that people are convenient for carrying.

For achieving the above object, the utility model provides following technical scheme: a kind of portable folding bicycle, manage before comprising vehicle frame, manage behind the vehicle frame, handlebar, saddle, seatpillar, front-wheel, trailing wheel, driver train, it is characterized in that before vehicle frame being provided with the assembly and above-mentioned two that is crossed as the X type between the pipe behind pipe and the vehicle frame manages the composition vehicle frames, wherein, the assembly outer tube of X type is that circular interior pipe in the middle clamping of two pipes about flat tube divided, and it is hinged in the centre, in the pipe two ends by being separately fixed at the hinge flexible connection on the pipe behind the pipe and vehicle frame before the vehicle frame, outer tube is two sections pivotally attached flat tubes before and after being divided into, the leading portion termination flexibly connects with the hinge that is fixed on the preceding pipe of vehicle frame, the back segment termination connects trailing wheel, trailing wheel is located between the two outer tube back segment terminations, connect front fork under the Guan Shanglian handlebar before the vehicle frame, fixing front-wheel in the front fork, pipe is gone up and is inserted the seatpillar fixed saddle behind the vehicle frame, is plugged in the supporting disk fixing between two outer tubes down.

Described driver train is a chain drive, by being located at external sprocket wheel of two-stage gear case and crank pedal in the outer tube, connects sprocket wheel and flywheel formation with chain.

Pedal axle in the described crank pedal can be around the crank half-twist.

Described handlebar be about two sections be plugged in the stage casing and fixedly form.

The beneficial effects of the utility model are: simple in structure, folding operation is easy, and fast, floor area is little, is easy to carry.
