Background technology

Existing bicycle inconvenience is carried, though existing multiple Folding Bicycle on the market, but can't it is folding very for a short time, can't allow bicycle and bus, subway etc. can combine use.

I improve to some extent to some parts that have folding bicycle now at Chinese patent application 200610028414.0 " Collapsible handle-bar of bicycle " and my Chinese patent application 200610163476.2 " folding stand " formerly formerly.

The utility model content

Because the above-mentioned defective of prior art, the purpose of this utility model is to provide a kind of collapsible very little, more portable portable folding bicycle that gets.

The purpose of this utility model is achieved in that a kind of portable folding bicycle, comprise vehicle body, folded chain, handgrip, barre, quick detach, front-wheel, trailing wheel, vehicle seat, vehicle seat folding stand etc., specially designed vehicle seat folding stand is made of last pipe fitting, following pipe fitting, folded chain, hoop shape part, bracing frame and folding base seat; Hoop shape part is two anchor ear sheets, a slice is welded on the pipe fitting, another sheet is by two-screw and the anchor ear sheet obvolvent that is welded on the pipe fitting, bracing frame is the shaped as frame that is bent into lower ending opening by the Metallic rod in circle footpath, folding base seat is one or two flanging to be arranged respectively with the metal piece in two holes, the metal piece of one end welding roll coil of strip circle, opening is left in the vertical centre of volume circle, the other end is installed a hinge that can overturn and is constituted, pipe fitting connects by folded chain up and down, and pin or open folded chain by quick detach, in the hoop shape part of last pipe fitting, embrace the top that clips bracing frame, the lower end of bracing frame penetrates in the volume circle hole of folding base seat, and by opening part with jump ring sheet or spring cotter location, volume circle hole with bracing frame and folding base seat, following pipe fitting is by being welded to connect on the Reversible hinge of folding base seat.

Above-mentioned handgrip comprises folding left and right handles, respectively have a comma shape disk in the left and right handles inner end, be sandwiched in a pair of horse-hof shape intermediate plate, be installed with a bolt in the middle of the two horse-hof shape intermediate plates, be used for fix shaft as comma shape disk on the left and right handles, the upper end of horse-hof shape intermediate plate also is installed with backer's bolt, and quick detach is deducted points with flute profile is not connected the inner end of left and right handles, so can allow left and right handles can launch effectively with folding.

Following position at barre also has a folded chain, and barre can be folded; In the centre of vehicle body, a folded chain is arranged, can be with the vehicle body doubling.

The beneficial effects of the utility model are: the last pipe fitting of vehicle seat folding stand, following pipe fitting, bracing frame form folding four-bar linkage by folded chain, hoop shape part and folding base seat, utilize the foldable properties of four-link mechanism, allow can to make zigzag between vehicle seat, vehicle seat folding stand, this three of vehicle body folding, left and right handles is collapsible, rod folding, vehicle body can doubling, finally can get bicycle folding of the present utility model very little.

Be described further below with reference to the technique effect of accompanying drawing, to understand the purpose of this utility model, feature and effect fully design of the present utility model, concrete structure and generation.
