Description

Single-beam type travel companion-bicycle

Technical field

The present invention relates to a kind of bicycle, especially a kind of single-beam type travel companion-bicycle.

Background technology

In existing technology, folding bicycle generally all is folding around the vehicle frame middle part, and folding back two-wheeled is overlapping basically, parallel.With this kind mode folding of bicycle, to carry in fact and inconvenient, its reason is: because wheel is generally all bigger, volume after folding is still bigger, so it is passable to put into the car boot, but the portable or shoulder back of the body is not suitable for really.If draw row or implementation, then this kind folded bicycle is because of receiving the restriction of folding mode, and it draws row or carries out poor-performing.

Summary of the invention

The objective of the invention is, a kind of single-beam type travel companion-bicycle is provided, solve the problem that the existing inconvenience of present folding bicycle draws row to carry.

Technical scheme of the present invention is: single-beam type travel companion-bicycle comprises double bracket, steamboat, vehicle frame back vent, trailing wheel, axis, crank and chain-wheel, the front-wheel of handlebar, saddle, seatpillar, seat tube, shelf, band steamboat; Set vehicle frame is responsible for and is divided into vehicle frame person in charge's leading portion and vehicle frame person in charge back segment; Vehicle frame is responsible for the place ahead that leading portion and the place of separating of vehicle frame person in charge back segment are positioned at axis and crank and chain-wheel; The place of separating that is responsible for back segment at vehicle frame person in charge leading portion and vehicle frame is provided with folding device, and its folding direction down; The distance of half breadth seat tube makes front-wheel after the vehicle frame person in charge is folding, can place between axis and the seat tube greater than the diameter of wheel; Folding device is fan-shaped rear portion by circular handwheel, triangle press strip, side, and nut, screw rod, side are that front portion, turning cylinder, inclined-plane, location, the locating notch of bar shaped constitutes; The side is to captive joint with vehicle frame person in charge leading portion with the vehicle frame person in charge front portion that back segment is captiveed joint, the side is bar shaped in fan-shaped rear portion; The side is that the front portion that fan-shaped rear portion and side are bar shaped is flexibly connected by set turning cylinder; Circular handwheel is captiveed joint with screw rod, and nut is that the anterior of bar shaped captiveed joint with the side, and screw is among nut, and the up-and-down movement of control triangle press strip is so that the function that realization compresses or unclamps.

The invention has the advantages that:

(1) method for folding is simple, quick, light.

(2) after folding, volume is flat, can stand, and floor area is little, relatively is suitable for getting into subway, bus.

(3) after folding, can draw row, and can load luggage, use, carry more convenient.

Among the figure: double bracket, 9 steamboats, 10 vehicle frame back vents, 11 trailing wheels, 12 axis, 13 crank and chain-wheels, 14 folding devices, 15 front-wheels, 16 circular handwheels, 17 triangle press strips, 18 sides that 1 handlebar, 2 vehicle frames are responsible for leading portion, 3 vehicle frames person in charge back segment, 4 saddles, 5 seatpillars, 6 seat tubes, 7 shelf, 8 band steamboats are that fan-shaped rear portion, 19 nuts, 20 screw rods, 21 sides are front portion, 22 turning cylinders, inclined-plane, 23 location, 24 locating notches of bar shaped.

The specific embodiment

Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; Single-beam type travel companion-bicycle comprises double bracket 8, steamboat 9, vehicle frame back vent 10, trailing wheel 11, axis 12, crank and chain-wheel 13, the front-wheel 15 of handlebar 1, saddle 4, seatpillar 5, seat tube 6, shelf 7, band steamboat; Set vehicle frame is responsible for and is divided into vehicle frame person in charge's leading portion 2 and vehicle frame person in charge back segment 3; Vehicle frame is responsible for leading portion 2 and vehicle frame and is responsible for the place ahead that the place of separating of back segment 3 is positioned at axis 12 and crank and chain-wheel 13; The place of separating that is responsible for back segment 3 at vehicle frame person in charge leading portion 2 and vehicle frame is provided with folding device 14, and its folding direction down; Axis 12 is apart from the distance of seat tube 6 diameter greater than front-wheel 15, makes front-wheel 15 be responsible at vehicle frame and can place between axis 12 and the seat tube 6 after folding; Folding device 14 is fan-shaped rear portion 18 by circular handwheel 16, triangle press strip 17, side, and nut 19, screw rod 20, side are that front portion 21, turning cylinder 22, inclined-plane 23, location, the locating notch 24 of bar shaped constitutes; The side is to captive joint with vehicle frame person in charge leading portion 2 with the vehicle frame person in charge front portion 21 that back segment 3 is captiveed joint, the side is bar shaped in fan-shaped rear portion 18; The side is fan-shaped rear portion 18 and the side is that the front portion 21 of bar shaped is flexibly connected by set turning cylinder 22; Circular handwheel 16 is captiveed joint with screw rod 20, and nut 19 and side are to captive joint in the front portion 21 of bar shaped, and screw rod 20 is contained among the nut 19, controls the up-and-down movement of triangle press strip 17, so that the function that realization compresses or unclamps.

When the present invention rides, shown in Figure 2 like Fig. 1: triangle press strip 17 is pushed down locating notch 24, and vehicle frame is responsible for leading portion 2 and is responsible for back segment 3 relative fixed with vehicle frame; When needs are folding, earlier saddle 4, seatpillar 5 are put down; Inhour is rotated circular handwheel 16 then; Control triangle press strip 17 up moves and breaks away from locating notches 24, is front portion 21, screw rod 20, the nut 19 of bar shaped with circular handwheel 16, triangle press strip 17, side again, is responsible for leading portion 2, handlebar 1, front-wheel 15 moving axis 22 inhours that rotate together with vehicle frame and rotates; After front-wheel is drawn close vehicle frame person in charge back segment 3; The circular handwheel 16 control triangle press strips 17 of clickwise move, and push down inclined-plane 23, location, and are shown in Figure 4 like Fig. 3; To dial down with the double bracket 8 usefulness pin of steamboat at last, the present invention promptly is folded into Fig. 3 state; Under this state, steamboat 9 lands, and holds handlebar, the fine row that draws of the present invention, and can also load a little luggage on the shelf 7.
