Seat cushion on pipe；
Described five-way is connected with wheel assembly by power drive system；
Described head tube and middle pipe are connected by cross bar, and cross bar is by can first cross bar and second of rotation folded against
Cross bar forms, and connecting between the first cross bar and the second cross bar has folding rotating mechanism, this folding rotating mechanism bag
Include and fix the fixed block being connected with the first cross bar and be connected with the second cross bar and turn relative to described fixed block
Dynamic movable block, is provided with the magnetic piece of cylinder, with described magnetic piece phase on described movable block on described fixed block
Corresponding face is provided with the circular groove that can accommodate described magnetic piece, and described fixed block is flexibly connected with movable block
One end connected by bearing pin；
With telescopic regulation structure on described first cross bar and the second cross bar, this telescopic regulation structure includes socket
On described first cross bar and the second cross bar, the binding of two connecting rod engagements is overlapped and is set in this binding set
Outside carries tightening ring jaggy, binding to put and be provided with the groove disposing described tightening ring.
Above-mentioned a kind of bicycle that can freely fold, the indentation, there of described tightening ring is provided with the screw of fastening
Nail.
Above-mentioned a kind of bicycle that can freely fold, the bore of described binding set is more than the first cross bar and second
The diameter of cross bar.
Above-mentioned a kind of bicycle that can freely fold, the circular groove on described movable block and described magnetic piece
Outer peripheral face match.
The invention have the benefit that to connect between the first cross bar of this bicycle and the second cross bar have folded turning
Motivation structure, when needs folding bicycle, rotates the first cross bar and the second cross bar so that the first cross bar and
Two cross bars fit together, and now, fold the fixed block on rotating mechanism and movable block also relatively rotates,
Circular groove on movable block merges absorption with the outer peripheral face kissing of fixed block magnetic piece, it is therefore prevented that the first cross bar
With second can separate between cross bar, fold rotating mechanism simple and convenient to operate；And in order to adapt to different body
With telescopic regulation structure on the requirement of high person, the first cross bar and the second cross bar, this telescopic regulation structure includes
It is socketed in the binding set of two connecting rod engagements on described first cross bar and the second cross bar and is set in this bundle
Tying up and carry tightening ring jaggy outside set, binding puts and is provided with the groove disposing described tightening ring, by tightening up
Circle controls the caliber size of binding set thus reaches to regulate two connecting rods on the first cross bar and the second cross bar and stretch
The purpose of contracting, adapts to the demand of different height person so that bicyclist cycles comfortable.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention；
Fig. 2 is that the present invention folds rotating mechanism；
Fig. 3 is the schematic diagram of telescopic regulation structure of the present invention.
Detailed description of the invention
Further understand by making the architectural feature to the present invention and effect of being reached have and recognize, in order to
Preferred embodiment and accompanying drawing coordinate detailed description, are described as follows:
As shown in Figure 1 to Figure 3, a kind of bicycle that can freely fold, including:
Head tube 1, the handle 2 being connected with head tube 1 and front component 3；
Middle pipe 4, the lower section of middle pipe 4 is provided with five-way, is arranged over liftable bench hassock tube 5 and arranges
Seat cushion 6 on bench hassock tube 5；
Five-way is connected with wheel assembly 8 by power drive system 7；
Head tube 1 and middle pipe 4 are connected by cross bar, and cross bar is by can first cross bar 9 and of rotation folded against
Two cross bars 10 form, and connect and have folding rotating mechanism 11, this folding between the first cross bar 9 and the second cross bar 10
Folded rotating mechanism 11 includes fixing, with the first cross bar 9, the fixed block 111 being connected and connecting with the second cross bar 10
The movable block 112 connect and rotate relative to fixed block 111, is provided with the magnetic piece of cylinder on fixed block 111
113, face corresponding with magnetic piece 113 on movable block 112 is provided with that can to accommodate the circular arc of magnetic piece 113 recessed
Groove 114, one end that fixed block 111 is flexibly connected with movable block 112 is connected by bearing pin 115；
With telescopic regulation structure 12 on first cross bar 9 and the second cross bar 10, this telescopic regulation structure 12
Including be socketed in two connecting rod 13 engagements on the first cross bar 9 and the second cross bar 10 binding overlap 121 and
It is set in outside this binding set 121 and carries tightening ring 122 jaggy, binding set 121 to be provided with arrangement and tighten up
The groove of circle 122, the indentation, there of tightening ring 122 is provided with the screw of fastening.
Connect between first cross bar 9 and second cross bar 10 of this bicycle and have folding rotating mechanism, at needs
During folding bicycle, rotate the first cross bar 9 and the second cross bar 10 so that the first cross bar 9 and the second cross bar
10 fit together, and now, the fixed block 111 folded on rotating mechanism also occurs relative with movable block 112
Rotating, the circular groove 114 on movable block 112 merges suction with the outer peripheral face kissing of fixed block magnetic piece 113
Attached, it is therefore prevented that to separate between the first cross bar 9 and the second cross bar 10, fold rotating mechanism and simply and be easy to
Operation；And in order to adapt to the requirement of different height person, with stretching on the first cross bar 9 and the second cross bar 10
Contracting adjustment structure, controls the caliber size of binding set 121 by tightening ring 122 thus reaches to regulate first
On cross bar 9 and the second cross bar 10, two flexible purposes of connecting rod 13, adapt to the demand of different height person, make
Obtain bicyclist and cycle comfortable.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The industry
Skilled person will appreciate that, the present invention is not restricted to the described embodiments, in above-described embodiment and description
The principle of the simply present invention described, the present invention also has without departing from the spirit and scope of the present invention
