Description

A kind of portable folding bicycle

Technical field

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

Background technology

The folding bicycle that many styles are arranged in the market can bring great convenience to people in daily use, can bring bicycle into subway and take, and also can bring bicycle folding into corridor and prevent to be stolen; But along with popularizing of folding bicycle; A lot of problems also highlight thereupon; Need realize that such as woman or the relatively poor people of muscle power carrying folding bicycle in peak time on and off duty, to take subway more difficult carrying folding bicycle up and down during subway through carrying; Existing in addition folding bicycle can't be carried, and parks the place ability bicycle parking that need find the special messenger to keep an eye in the business district, otherwise is very easily stolen.

In sum, do not have a kind of folding bicycle can overcome above various drawback on the market, realize collection handled easily, health environment-friendly, saving muscle power, be fit to advantage folding bicycles such as folding.

The utility model content

The utility model wants the technical solution problem to be: to the above-mentioned defective of prior art; A kind of portable folding bicycle is provided; Being convenient for carrying in the time of can going out outside for people, is again a kind of vehicle of convenient environment friendly, and its folding invention has not only been saved parking space and also reduced the physical demands when carrying; Be applicable to all kinds of crowds, especially provide convenient for old man and the relatively poor people of muscle power.

In order to solve above technical matters; The portable folding bicycle of the utility model; Comprise vehicle frame and be installed in chain wheel, handlebar and the seat cushion on the vehicle frame, said vehicle frame is the single-beam vehicle frame, and said single-beam is provided with a horizontal segment; On said horizontal segment, be provided with two place's folding points, be separately installed with first folding hinge and second folding hinge on the said folding point; Said chain wheel axis is installed on the upright beam of said vehicle frame.

This structure is folding through twice, makes parallel the landing of front and back two-wheeled of bicycle, in use can handlebar be become handle, moves as the same folding bicycle that hauls easily of suitcase.

The utility model further limits technical scheme: aforementioned portable folding bicycle, said folding point are the tooth occlusion structure, and are fixed by folding control latch.

Aforementioned portable folding bicycle is provided with spring reset mechanism in the said folding control latch.

Aforementioned portable folding bicycle, carrying of folding bicycle for ease, the said handlebar place of connecting to ground also is provided with the folding point of door assembly with hinge and glass in right hand and left structure, and is regulated fixing by folding control sluice.

Further, aforementioned portable folding bicycle, said handlebar and seat cushion are installed on the said vehicle frame through expansion link, and are regulated fixing by the expansion link control sluice.

The utility model beneficial effect: the crossbeam of the utility model has adopted folding structure twice, make folding bicycle front and back wheel is parallel in folding back lands, structure is more reasonable, is convenient for carrying, and is safe and reliable.

This folding bicycle is conserve space not only, has also made things convenient for people's trip simultaneously, and this bicycle uses simple, and can fold whenever and wherever possible and carry, and saves physical.

The specific embodiment

Present embodiment provides a kind of portable folding bicycle; Structure such as Fig. 1 comprise vehicle frame 3 and are installed in chain wheel 2, handlebar 1 and the seat cushion on the vehicle frame that vehicle frame is the single-beam vehicle frame to shown in Figure 3; Single-beam is provided with a horizontal segment 4; On horizontal segment, be provided with two place's folding points, folding point is the tooth occlusion structure, and by folding control latch fixing 5; Be separately installed with first folding hinge 6 and second folding hinge 7 on the folding point; The chain wheel axis is installed on the upright beam 8 of vehicle frame; Be provided with spring reset mechanism 9 in the folding control latch; Handlebar 1 also is provided with the folding point 10 of door assembly with hinge and glass in right hand and left structure with vehicle frame 3 junctions, and regulates fixing by folding control sluice 11; Handlebar 1 is installed on the vehicle frame through expansion link 13 and 13 ' with seat cushion 12, and regulates fixing by expansion link control sluice 14 and 14 '.

The folding step of present embodiment is following: (1) draws the control latch that opens first folding hinge that the front portion of bicycle is lifted to right back folding, and first folding hinge at the folding position of vehicle frame horizontal segment this moment is converted into 90 °; It is folding to the right abaft to draw the control latch that opens second folding hinge to continue the front portion of vehicle frame again; Second folding hinge at the folding position of the horizontal segment of vehicle frame is converted into 90 ° at this moment, and process folds for preceding twice, and the front-wheel of bicycle has turned to 180 °; Have that trailing wheel is parallel to land, as shown in Figure 4.

Control sluice of (2) unclamping leading expansion link and the folding control sluice of tap are pulled out the expansion link of folding flexible tap, and tap is folding, as shown in Figure 5.

(3) unclamp seat cushion expansion link control sluice seat cushion is put down, as shown in Figure 6.

The vehicle frame part that (4) will link to each other with front and back two wheels respectively with ready two belts at last and the tap that stretches are tied up tightly with the folding position of vehicle frame horizontal segment, are about to this folding bicycle and fold and finishes.

Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
