Occurred all multiple folding bicycles in the market, but still allowed people regrettably, folding bicycle efficiently but can not fold very for a short time, and but folding rate is unhappy for folding a little bit smaller a little bicycle.

Summary of the invention:

Folding quickly in line with carrying out, allow it folding very for a short time again, make it meet the portable of people's demand, design a quick-folding portable bicycle; The technical issues that need to address are, a kind of technology is provided, and make bicycle can two pipeline in one step folding, with solve can fold quick, the convenient bicycle of the quick-folding that can fold very for a short time again.

The object of the present invention is achieved like this, quick-folding portable bicycle comprises folding pedestal, the vehicle body side arm, the seat bar, pipe link, steering handle, folder, front-wheel, trailing wheel and man power driving mechanism, it is characterized in that: folding pedestal is the saddle shape, be arranged on the central authorities of bicycle, the sleeve pipe of bottom welding one axis, sleeve pipe one face down bonding connects a pair of back vent, the movable neck that is connected in folding pedestal of vehicle body side arm, the movable upper end that is connected in folding pedestal of seat bar, end at vehicle body side arm and seat bar flexibly connects a pipe link, makes folding pedestal, the vehicle body side arm, the seat bar, pipe link forms a four-bar linkage.

The invention has the beneficial effects as follows: owing to adopted folding pedestal, make and produce the quick-folding portable bicycle work simplification, cost reduces, owing to adopted folding pedestal to cooperate the folded form of four-bar linkage again, just folding faster, folding effect is better.

Description of drawings:

Fig. 1 is a complete vehicle structure scheme drawing of the present invention;

Fig. 2 is folding pedestal of the present invention and local structure scheme drawing;

Fig. 3 is folding process figure of the present invention;

Fig. 4 is that the present invention finishes the first partly folding scheme drawing;

Fig. 5 is the folding scheme drawing that finishes of the present invention.

The specific embodiment:

Among the figure: 1---folding pedestal, 2---the vehicle body side arm, 3---the seat bar, 4---pipe link, 5---steering handle, 6---front-wheel, 7---trailing wheel, 8---man power driving mechanism;

The invention will be further described below in conjunction with Fig. 1, Fig. 2:

Described folding pedestal 1 comprises: pair of lamina saddle shape blanked part 11 (hereinafter to be referred as saddle), the sleeve pipe 12 of axis is installed in welding one, sleeve pipe 12 also welds a pair of back vent 13, between saddle 11 and a pair of back vent 13, be welded with reinforcing chip 14, neck in saddle is installed with the 3rd pin 15, the 3rd pin 15 movable connection vehicle body side arms 2, the 3rd pin 15 is slightly oblique, so that vehicle body side arm 2 is an axle with the 3rd pin 15, rotation is folded to about 120 degree during corners, and front-wheel 6 and trailing wheel 7 can reach the effect that staggers; In the upper end of saddle 11, also be installed with the 4th pin 16, the four pins 16 movable Connection Block bars 3, making a bar 3 can the 4th pin 16 be axle, rotates folding; The nose button 17 that also has a band opening in the upper end of 11 1 of saddle, the quick detach 21 on nose button 17 and the vehicle body side arm 2 cooperates, and can lock folding pedestal 1 and vehicle body side arm 2.Described vehicle body side arm 2 also comprises a quick detach 21, one quick detach rotating shaft, 22, the first pins 23 is characterized in that, vehicle body side arm 2 is done movable the connection with the 3rd pin 15 on the folding pedestal 1, on the both sides that flexibly connect point,, quick detach 21 is installed in the quick detach rotating shaft 22 Yi Bian a quick detach rotating shaft 22 is installed, the end of another side vehicle body side arm, be installed with first pin, 23, the first pins, 23 movable connection one pipe links 4, the other end of pipe link 4 is done movable the connection with second pin 32 of an end of seat bar 3.
