Embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only the part of the embodiment of the present invention, rather than whole embodiments.It is common based on the embodiment in the present invention, this area
All other embodiment that technical staff is obtained under the premise of creative work is not made, belong to the model that the present invention protects
Enclose.
Embodiment one:
Fig. 1-7 are referred to, the embodiment of the present invention includes:A kind of loading folding bicycle, including front-wheel 1, front fork 2, preceding head
3rd, folder 4, front bar 5, handlebar 6, crossbeam 7, fixes sleeve 8, rotational sleeve 9, seat pipe 10, seat bar 11, saddle 12, back vent 13,
Trailing wheel 14, foot pedal apparatus 15, transmission device 16, support board 17;Folder 4 is housed, the rear end of crossbeam 7 is set in the front bar 5
Fixes sleeve 8 and rotational sleeve 9 are equipped with, the radial rotary axle of the rotational sleeve 9 is horizontally fixed on crossbeam 7, the crossbeam 7
By being formed with the preceding first 3 front-axle beam 7-1 being connected and the back rest 7-2 grafting being connected with back vent 3, the front-axle beam is plugged in the back rest
And it can be moved in the rear in beam.I.e. front-axle beam and the back rest are Collapsible structure together, and length of the front-axle beam in the back rest can stretch
Regulation, two wheel spacing are adjusted with this, crossbeam is shortening state during folding.
The crossbeam 7 is double circular tube structures, is made up of the first beam pipe 7-3 parallel to each other and the second beam pipe 7-4, the first beam
Pipe 7-3 internal diameter is more than the external diameter of seat pipe 10, and the second beam pipe 7-4 is formed by front-axle beam 7-1 and back rest 7-2 grafting, is Collapsible structure,
Front-axle beam 7-1 external diameters are less than back rest 7-2 internal diameters, and are realized with hitching post in front and rear beam junction circumferentially fixed, and front-axle beam 7-1 afterbodys are provided with
Convex clip prevents from overexerting during outer drawing and all pulls out front end from back rest 7-2;The seat bar 11 can be inserted into seat pipe 10 and use bolt
Post is fixed and prevents from circumferentially rotating.
The bottom of the seat pipe 10 is circumferentially provided with the flange for preventing the seat pipe 10 from departing from the rotational sleeve 9.
The radial rotary axle of the rotational sleeve 9 and the first beam pipe 7-3 axial centre symmetry axis are in same level
It is and orthogonal.Support board 17 is hinged on crossbeam the first beam pipe 7-3 both sides.
Further, handlebar 6 is included vertical 6-1, horizontal 6-2, handle 6-3, and is arranged on the fastener 6-4 on horizontal 6-2,
Handle 6-4 is flexibly connected with horizontal 6-2;The bottom of saddle 12 is additionally provided with one and takes part 12-1.Foot pedal apparatus 15 includes pedal 15-1, song
Shaft arm 15-2, pedal 15-1 are flexibly connected with crank arm 15-2.
When bicycle normally travel, front bar 5 is conllinear with preceding first 3, is fixed by folder 4, the central shaft of fixes sleeve 8,
The axial centre axle of rotational sleeve 9, the central shaft of seat pipe 10, the central shaft of seat bar 11 are conllinear.The depth that seat bar 11 is inserted in seat pipe 10
Degree influences the height of saddle 12, and the bottom of seat pipe 10 is fixed with fixes sleeve 8 by keyhole part, prevents seat pipe 10 from circumferentially rotating, and is carried
Thing plate 17 turns to horizontal level and fixation, realizes loading function.
When bicycle folds, the second beam pipe 7-4 front-axle beam 7-1 is entirely insertable back rest 7-2 and fixed with hitching post, seat bar 11
It is entirely insertable in seat pipe 10, unclamps the bolt of the bottom of fixes sleeve 8, lift the constraint that seat pipe 10 disengages it from fixes sleeve 8 upwards
Without departing from rotational sleeve 9, it is entirely insertable after being rotated with the rotary shaft of rotational sleeve 9 to horizontal level in the first beam pipe 7-3;Beat
Open foldable device 4, the front bar 5 are folded to horizontal level, and now, front bar 5, crossbeam 7, the three of seat pipe 10 are parallel to each other, rotate two
Hand 6-3 makes its parallel to each other and vertical with horizontal 6-2, will be taken on saddle 12 part 12-1 with the fastener 6-4 on horizontal 6-2
Fasten, fixed fold state.
Further, turnover pedal 15-1 makes it parallel with crank arm 15-2, reaches the purpose of convergence foot pedal apparatus 15.
Embodiment two:
Refer to Fig. 1-7, a kind of loading folding bicycle, including front-wheel 1, front fork 2, preceding first 3, folder 4, front bar 5, car
6, crossbeam 7, fixes sleeve 8, rotational sleeve 9, seat pipe 10, seat bar 11, saddle 12, back vent 13, trailing wheel 14, foot pedal apparatus 15,
Transmission device 16, support board 17;Folder 4 is housed, the rear end of crossbeam 7 is provided with fixes sleeve 8 and rotated in the front bar 5
Sleeve 9, the radial rotary axle of the rotational sleeve 9 are horizontally fixed on crossbeam 7, the crossbeam 7 by with preceding first 3 front-axle beam being connected
7-1 and the back rest 7-2 grafting being connected with back vent 3 form, and the front-axle beam is plugged in the back rest and can moved in the rear in beam
It is dynamic.I.e. front-axle beam and the back rest are Collapsible structure together, and length of the front-axle beam in the back rest can adjust two wheels with telescopic adjustment with this
Spacing, crossbeam is shortening state during folding.
The crossbeam 7 is single tube, is made up of front-axle beam 7-1 and back rest 7-2 grafting, and front-axle beam 7-1 can stretch shifting in back rest 7-2
Position at least one outer radius size of seat pipe 10 higher than the main body of crossbeam 7 dynamic, that the rotary shaft of rotational sleeve 9 is fixed, during folding before
Beam 7-1 is entirely insertable back rest 7-2 and fixed with hitching post, and seat bar 11 is entirely insertable in seat pipe 10, unclamps the bottom of fixes sleeve 8
Bolt, upward lifting seat pipe 10 disengages it from the constraint of fixes sleeve 8 without departing from rotational sleeve 9, with the rotary shaft of rotational sleeve 9
Flatly inserted forwards after rotation;Foldable rear seat pipe 10 is horizontal to be fixed on above crossbeam 7;Other connections are with folding mode with real
Apply example one.
A kind of loading folding bicycle of the present invention, folding step are few, it is only necessary to which 3-4 steps can be completed to fold, Foldable square
Formula is simple, and regular shape after folding, the volume reduced after folding is obvious, and car can be made to reduce 40%- respectively in length, short transverse
50%, space is saved very much, be easy to carry storage, does not also change the traveling structure of two wheels after folding, and solves to carry simultaneously
When bicycle and small article the problem of difficult.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
The equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks
Domain, it is included within the scope of the present invention.
