Abstract
The utility model relates to a quickly folding bicycle, which mainly comprises a bicycle frame, a bicycle handle, wheels, a cushion, driving sprockets and braking devices, wherein the bicycle frame is composed of a front vertical pipe, a bicycle body pipe, a front horizontal pipe and a back horizontal pipe; the front vertical pipe, the bicycle body pipe, the front horizontal pipe and the back horizontal pipe are formed into a shape similar to an equilateral triangle; the connecting positions of the front vertical pipe and the bicycle body pipe, the front vertical pipe and the front horizontal pipe, the back horizontal pipe and the bicycle body pipe, and the back horizontal pipe and the front horizontal pipe are in hinge connection; the connecting point of the front horizontal pipe and the back horizontal pipe is positioned on the lower part of the front end of the back horizontal pipe; the connecting position of the front horizontal pipe and the back horizontal pipe and the front horizontal pipe are provided with a fold proof plate; a space limiting plate is arranged between the back horizontal pipe and the front horizontal pipe. The utility model makes the folding and the opening of the folding bicycle fast and convenient.
Description
Technical field
The utility model relates to bicycle, specifically refers to a kind of fast-folded type bike.
Background technology
Present Folding Bicycle mostly is laterally folded formula, and soon the several positions of vehicle frame body are blocked and connected with hinge.With 180 ° of bicycle front portion or posterior rotation, make bicycle when folding from laterally turning back.But this folding mode is in folding and opening procedure, rotate foldingly to half weight of car body, also will carry out the safety inspection of each point of connection when opening, and program is many, uses inconvenience.
Summary of the invention
The purpose of this utility model is to propose a kind of quickly folding type bicycle, and its novel folding mode of mat makes the folding of Folding Bicycle become very simple and convenient with opening procedure, really reaches the folded purpose of speed.
A kind of fast-folded type bike of the present utility model, mainly comprise vehicle frame, handlebar, wheel, cushion, driving chain wheel and brake gear, described vehicle frame is made up of preceding standpipe, vehicle body pipe, preceding transverse tube and rear cross-tube, and described preceding standpipe, vehicle body pipe and forward and backward transverse tube are formed one and be similar to equilateral triangle; And preceding standpipe all adopts hinge to be connected with vehicle body pipe and rear cross-tube with preceding transverse tube junction with preceding transverse tube junction, rear cross-tube with vehicle body pipe and preceding standpipe.
The point of connection of transverse tube and rear cross-tube is positioned at rear cross-tube front end below before described.Before described, be provided with an anti-flap on the junction of transverse tube and rear cross-tube, the preceding transverse tube.Between described rear cross-tube and preceding transverse tube, be provided with a positioning plate.
The utility model has the advantages that and make the folding of Folding Bicycle and open very quick, easy.
Description of drawings
Fig. 1 is the structural representation of quickly folding type bicycle of the present utility model;
Fig. 2 is last (preceding) hinge arrangement scheme drawing
Fig. 3 is a back hinge scheme drawing;
Fig. 4 is that hinge reaches anti-folded block, limiting stopper structural representation down.
Among the figure: 1 handlebar, 2 upper hinges, 3 preceding standpipes, 4 preceding transverse tubes, 5 preceding hinges, 6 front-wheels, 7 vehicle body pipes, 8 cushions, 9 sprocket wheels, 10 rear cross-tubes, 11 back hinges, 12 trailing wheels, 13 times hinges, 14,15 bearing pins, 16 anti-folded blocks, 17 limiting stoppers.
The specific embodiment
Now the utility model is described in further detail in conjunction with an embodiment and accompanying drawing thereof.
By Fig. 1, quickly folding type bicycle of the present utility model, mainly form by vehicle frame, handlebar 1, front-wheel 6, trailing wheel 12, cushion 8, driving chain wheel 9 and brake gear, described vehicle frame is made up of with rear cross-tube 10 preceding standpipe 3, vehicle body pipe 7, preceding transverse tube 4, and described preceding standpipe 3, vehicle body pipe 7 are formed one with forward and backward transverse tube 3,4 and be similar to equilateral triangle.
Before is connected with upper hinge 2 between standpipe 3 and the vehicle body pipe 7, former hinge 5 is connected between preceding standpipe 3 and the preceding transverse tube 4, later hinge 11 is connected between rear cross-tube 10 and the vehicle body pipe 7, following hinge is connected between rear cross-tube 10 and the preceding transverse tube 4, referring to Fig. 2, Fig. 3.
Referring to Fig. 4, the point of connection between preceding transverse tube 4 and the rear cross-tube 10 is positioned at the below of rear cross-tube 10 front ends, and is lower than preceding hinge 5 and back hinge 11, to guarantee when front-wheel is subjected to clashing into, can not fold voluntarily.Transverse tube 4 is provided with an anti-flap 16 with the junction of rear cross-tube 10 before described, transverse tube 4 rearward end top and prop up the front end of rear cross-tube 10 before this anti-flap is installed in, folding voluntarily potential safety hazard when eliminating driving.In addition be provided with a positioning plate 17 between described rear cross-tube 10 and preceding transverse tube 4, this positioning plate is installed in the below of rear cross-tube 10 front portions, and the rearward end of transverse tube before propping up when the folding position, when folding to limit before relative position between standpipe 3 and the vehicle body pipe 7.
When folding, carry, make its bending, just other each hinge can correspondingly collapse as long as will play on the hinge 13.Carry as long as in fact hold on the sprocket wheel 9, as long as whole folding process is 1 second.When opening, by lower sprocket hinge joint is stretched, at this moment other each hinge joint is also opened simultaneously, and bicycle just can recover running condition, and is very convenient.
