Suffer from.And the physical power loss of parent can be speeded in this way.
Utility model content
For the above defect of the existing technology, the main purpose of the utility model is to overcome the deficiencies in the prior art
Place discloses a kind of Telescopic bicycle, front frame, Rear frame, driving crank, power-assisted crank, dynamic link, connecting rod branch
It manages after support, fixing bundle, seat cushion, the flexible front tube of the front frame and the flexible of the Rear frame and slidably connect, and lead to
It crosses fixed device to fix, the link supports are fixed on after described stretch on pipe by the fixing bundle, the link supports two
The rotatable installation power-assisted crank in side, the rotatable installation driving crank in the two sides of the Rear frame, the transmission
Crank is connect with the ipsilateral power-assisted crank by the dynamic link, and the seat cushion is separately mounted to the Rear frame and institute
It states in link supports.
Further, the fixing bundle includes card under blocking on fixing and being fixed, blocks in the fixation and blocks under the fixation
Be detachably fixed, it is described it is flexible after pipe be placed in the fixation under card and the fixation between card.
Further, card and the interior setting frictional layer of card under the fixation in the fixation.
The utility model obtain the utility model has the advantages that
The utility model can adjust the spacing between front frame and Rear frame, and installation connects on pipe 21 after stretching
Bar support, cooperation dynamic link realize that driving crank is driven mutually with power-assisted crank, make to ride more easily, can also be used as religion
It learns and uses vehicle, religion child learns to cycle, furthermore it is possible to observe child's state in real time in ride, prevents outer generation, and increase
Add interaction of riding, improves enjoyment of riding.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of Telescopic bicycle of the utility model；
Fig. 2 is the structural schematic diagram of the non-installing connecting rods support of bicycle；
Fig. 3 is the right view of link supports；
Fig. 4 is the main view of link supports；
Appended drawing reference is as follows:
1, front frame, 2, Rear frame, 3, driving crank, 4, power-assisted crank, 5, dynamic link, 6, link supports, 7, fixation
Beam, 8, fixed device, 9, seat cushion, 11, flexible front tube, 21, it is flexible after manage, 71, it is fixed on block, 72, fixed lower card.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and implement
Example is described in further detail the utility model.It should be appreciated that specific embodiment described herein is only to explain this reality
With novel, it is not used to limit the utility model.
A kind of Telescopic bicycle of the utility model, front frame 1, Rear frame 2, driving crank 3, power-assisted crank 4, power
Connecting rod 5, link supports 6, fixing bundle 7 and seat cushion 9, the flexible front tube 11 of front frame 1 and Rear frame 2 it is flexible after pipe 21 slidably
Connection, and it is fixed by fixed device 8；It can be by 11 sets of flexible front tube after flexible in pipe 21, and then realizes flexible
Front tube 11 and it is flexible after being slidably connected between pipe 21；Fixed device 8 can be lock screw, be also possible to clamping device, lead to
Cross clamping it is flexible after pipe 21, clamping force is conducted to flexible front tube 11 by pipe 21 after flexible, and then by flexible 11 He of front tube
Pipe 21 is fixed after flexible.
Link supports 6 by fixing bundle 7 be fixed on it is flexible after on pipe 21, the rotatable installation power-assisted in 6 two sides of link supports
Crank 4, the rotatable installation driving crank 3 in the two sides of Rear frame 2, driving crank 3 and ipsilateral power-assisted crank 3 are connected by power
Bar 5 connects, likewise, the driving crank 3 of the other side is connect with power-assisted crank 4 by dynamic link 5, by trampling driving crank
Footboard drives gear rotation on 3, and then when driving rear wheel, pass through dynamic link 5 and power-assisted crank 4 is driven to rotate；When
When trampling power-assisted crank 4, drives driving crank 4 to rotate by dynamic link 5, rotate gear, and then drive rear wheel.Seat
Pad 9 is separately mounted in Rear frame 11 and link supports 6.It is ridden simultaneously with meeting two people.
Wherein, fixing bundle 7 includes card 71 and fixed lower card 72 on fixed, and card 71 and fixed lower card 72 are detachably solid in fixation
It is fixed, it is flexible after pipe 21 be placed on fixed between card 71 and fixed lower card 72, by blocking between 71 and fixed lower card 72 in fixation
Clamping force by link supports 6 be fixed on it is flexible after on pipe 21.Preferably, friction is set in card 71 and fixed lower card 72 in fixation
Layer, increase fixing bundle 7 and it is flexible after frictional force between pipe 21, prevent from loosening when in use, at the same protect it is flexible after pipe 21 not
It is fixed the damage of beam 7.
When the utility model is used, unclamping fixed device 8, the spacing between front frame 1 and Rear frame 2 is adjusted, then
Locking and fixing device 8, two people are sitting in respectively on seat cushion 9, and one of people controls handlebar, and two people trample foot pedal respectively,
It can effortlessly ride in this way.If one child of an adult rides, child is sitting in the seat cushion 9 in link supports 6, adult
It is sitting on the seat cushion 9 in Rear frame 2, in ride, adult, which can have a try, observes the state of child, prevents from unexpectedly sending out
It is raw, because back seat, on rear-wheel, crying for child is easy to be caught in rear-wheel, child is damaged, it is also possible to child occur and not sit
Surely, situations such as causing child to drop.It is interacted in addition, can make to generate between adult and child in this way, increases the enjoyment of movement, and
And the vehicle also can be as teaching vehicle be cycled, religion child learns cycling.
The utility model obtain the utility model has the advantages that
The utility model can adjust the spacing between front frame and Rear frame, and installation connects on pipe 21 after stretching
Bar support, cooperation dynamic link realize that driving crank is driven mutually with power-assisted crank, make to ride more easily, can also be used as religion
It learns and uses vehicle, religion child learns to cycle, furthermore it is possible to observe child's state in real time in ride, prevents outer generation, and increase
Add interaction of riding, improves enjoyment of riding.
The above is only the preferred embodiments of the utility model, are not used to limit the scope of the utility model；If
The spirit and scope for not departing from the utility model, are modified or replaced equivalently the utility model, should all cover in this reality
In novel scope of protection of the claims.
