Description

Folding bicycle.

The utility model relates to a kind of folding bicycle, belongs to the vehicle.

At present the bicycle that uses of people is commonly fixed type, carries, moves all inconvenient, and floor area is not big the time spent.In recent years, folding bicycle comes out, but because the structure more complicated, and is folding and open inconvenience, fails to promote always.Chinese patent 94231413 discloses a kind of full folding small-wheeled bicycle, handlebar is folding to be utilized finger to slide at cam spiral end face to realize, front and back wheel merges with folding hinge, saddle is with inside and outside Taper Pipe, locking pull bar lifting, this utility model auxiliary component is many, complex structure, inconvenience is made, and step tread plate can not fold.

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of structure more advantages of simple, folding bicycle that folding effect is good, easy to use are provided.

The purpose of this utility model is achieved in that

Vehicle frame is the cuboid framework, and its front end is captiveed joint with car fork cover; There is groove at handlebar crossbeam two ends, and handlebar is loaded in the groove respectively, and flexibly connect by set pin and handlebar crossbeam, and the outside of set pin also is connected with the handlebar crossbeam by removable pin; The car fork is connected through the hinge for the fork of getting on or off the bus, and there are two otic placodes the both sides, top of the fork of getting off, have crossed bearing pin on two otic placodes, and the upper vehicle fork bottom is equipped with position-limited lever, and it places between bearing pin inboard and two otic placodes; The rear lower both sides of vehicle frame are separately installed with slideway, and the axis two ends place in the slideway; The pedal rod end is a flute profile, and the step tread plate axle places in the groove, and captives joint with the little axle on being installed on pedal rod, and on the pedal rod of the opposite side of the cooresponding step tread plate axle of little axle active pin shaft is installed; Rear wheel support flexibly connects with the transverse axis that is installed in the frame rear portion, captives joint with bottom bracket axle, and the rear wheel support middle part is porose, is installed with bearing pin in the hole, and cross in the hole on vehicle frame at the bearing pin two ends; Both sides, vehicle frame back upper place respectively are equipped with a Saddle cover, and the vehicle seat axle mounting has the adjustment hole on the vehicle seat axle in Saddle cover, and be connected with Saddle cover by bearing pin.

Compared with prior art, advantage of the present utility model is simple and reasonable, and volume after folding is little, is easy to carry to deposit, and has more practicality.

The explanation of accompanying drawing drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a handlebar mounting structure scheme drawing of the present utility model.

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

Vehicle frame of the present utility model (13) is the cuboid framework, and its front end is captiveed joint with car fork cover (5); There is groove (2) at handlebar crossbeam (1) two ends, and handlebar (3) is loaded on respectively in the groove (2), and flexibly connect by set pin (4) and handlebar crossbeam (1), and the outside of set pin (4) also is connected with handlebar crossbeam (1) by removable pin (31); The car fork is the fork of getting on or off the bus (6,11), connect by hinge (12), there are two otic placodes (9) both sides, top of the fork (11) of getting off, have crossed bearing pin (8) on two otic placodes (9), upper vehicle fork (6) bottom is equipped with position-limited lever (7), and it places between bearing pin (8) inboard and two ears (9) plate; The rear lower both sides of vehicle frame (13) are separately installed with slideway (22), and axis (14) two ends place in the slideway (22); Pedal rod (15) end is a flute profile, step tread plate axle (17) places in the groove, and captive joint with the little axle (16) on being installed on pedal rod (15), and on the pedal rod (15) of the opposite side of little axle (16) cooresponding step tread plate axles (17) active pin shaft (29) is installed; Rear wheel support (19) flexibly connects with the transverse axis (21) that is installed in frame (13) rear portion, captives joint with bottom bracket axle, and rear wheel support (19) middle part is porose, is installed with bearing pin (18) in the hole, and cross in the hole on vehicle frame (13) at bearing pin (18) two ends; Vehicle frame (13) both sides, back upper place respectively are equipped with a Saddle cover (28), and vehicle seat axle (25) is installed in the hole (23) of Saddle cover (28), and adjustment hole (26) is arranged on the vehicle seat axle (25), and are connected with Saddle cover (28) by bearing pin (27).Adjustment hole (26) on the vehicle seat axle (25) is 1-5.Can regulate the height of vehicle seat (24) by adjusting hole (26).

When not using the utility model, pull up removable pin (31), handlebar (3) can set pin (4) be axially interior folding; Pull up bearing pin (8), get off fork (11) and front-wheel (10) can be axially interior rotary folding by hinge (12); Extract active pin shaft (29), step tread plate axle (17) and step tread plate (30) can be around little axle (16) rotary foldings; Extract bearing pin (18), rear wheel support (19), trailing wheel (20) and axis (14) can be around the inside rotary foldings of transverse axis (21) together with pedal rod (15), and at this moment, axis (14) is along slideway (22) upward movement; Extract bearing pin (27), vehicle seat (24) withdrawal that can descend.After folding, the utility model is and the similar cuboid of vehicle frame (13), carry deposit all very convenient.
