The specific embodiment

Below in conjunction with accompanying drawing, the preferred implementation of a kind of body-building bicycle of the present invention is made detailed description:

Embodiment one

As shown in Figure 1, the enhancing body resistance bicycle mainly comprises handlebar 1 and vehicle body 2, and handlebar 1 rotates the head that is arranged on vehicle body 2; Front-wheel 3 is installed on the handlebar 1; The medium position of vehicle body 2 rotates an axis 8 is set, and the afterbody of vehicle body 2 is installed trailing wheel 7, fixed installation fluted disc 4 on the axis 8 at vehicle body 2 middle parts; On the trailing wheel 7 with flywheel 6 of axle mounting; Fluted disc 4 and flywheel 6 are in transmission connection by chain 5.

As shown in Figures 2 and 3, captive joint with an end of curved bar 9 in the both ends of axis 8, and two curved bars 9 are that the center is centrosymmetric with axis 8, and the movable end of curved bar 9 can rotate synchronously with fluted disc 4; An end of the movable end of curved bar 9 and pipe link 10 is hinged, and another end of pipe link 10 and the middle part of pedal 11 are hinged; Pedal 11 is the shape of 60 ° of left end perks, and the hinge-point of pipe link 10 and pedal 11 is positioned at the bending point place at pedal 11 middle parts, and the left end of pedal 11 is hinged on the vehicle body 2; Vehicle body 2 each side be provided with a pedal 11 and symmetrical being hinged on the vehicle body 2.

The hinge-point of vehicle body 2 and two pedals 11 is positioned at the place ahead of fluted disc 4, the distance at hinge-point and fluted disc 4 centers is d=30cm, curved bar 9 is r=4cm with the radius of rotation of the hinge-point of pipe link 10, the distance of two hinge-points on the pipe link 10 is m=15cm, the distance of two hinge-points on the pedal 11 is R=20cm, such design has guaranteed that along with alternately the swinging up and down of pedal 11 pipe link 10 can drive the left-hand revolution that curved bar 9 continues, thereby realizes continuing transmission.

In the time of the work of enhancing body resistance bicycle, trample the pedal 11 in left side downwards, the pipe link 10 that pedal 11 drives the left side moves down, pipe link 10 pulling curved bars 9 rotate counterclockwise, rotate counterclockwise thereby drive fluted disc 4, along with left pedal 11 moves down, the curved bar 9 on right side rotates up, drive the pipe link 10 on right side, and then the pedal 11 on pulling right side moves up; When the pedal 11 in left side arrives lower limit, the pipe link 10 and the curved bar 9 on right side have turned over flex point, the moment of the pipe link 10 pulling curved bars 9 on right side becomes anticlockwise moment at this moment, trample the pedal 11 on right side downwards, and then the pipe link 10 that drives the right side moves down, and pipe link 10 pulling curved bars 9 rotate counterclockwise.Along with alternately trampling left and right sides pedal 11 it is back and forth swung up and down, fluted disc 4 is by continual driven in rotation, thereby realizes constantly moving ahead of bicycle, and people's pushes pedals 11 simulations action of running, and realized the purpose of taking exercises simultaneously.

Embodiment two

The each several part annexation and the embodiment one of the body-building bicycle of present embodiment are identical, and difference is the design size of driver train:

The hinge-point of vehicle body 2 and two pedals 11 is positioned at the place ahead of fluted disc 4, the distance at hinge-point and fluted disc 4 centers is d=25cm, curved bar 9 is r=2cm with the radius of rotation of the hinge-point of pipe link 10, the distance of two hinge-points on the pipe link 10 is m=10cm, the distance of two hinge-points on the pedal 11 is R=23cm, such design has guaranteed that along with alternately the swinging up and down of pedal 11 pipe link 10 can drive the left-hand revolution that curved bar 9 continues, thereby realizes continuing transmission.

In the time of the work of enhancing body resistance bicycle, trample the pedal 11 in left side downwards, the pipe link 10 that pedal 11 drives the left side moves down, pipe link 10 pulling curved bars 9 rotate counterclockwise, rotate counterclockwise thereby drive fluted disc 4, along with left pedal 11 moves down, the curved bar 9 on right side rotates up, drive the pipe link 10 on right side, and then the pedal 11 on pulling right side moves up; When the pedal 11 in left side arrives lower limit, the pipe link 10 and the curved bar 9 on right side just arrive flex point, under the rotator inertia effect, the moment of the pipe link 10 pulling curved bars 9 on right side becomes anticlockwise moment at this moment, trample the pedal 11 on right side downwards, and then the pipe link 10 that drives the right side moves down, and pipe link 10 pulling curved bars 9 rotate counterclockwise.Along with alternately trampling left and right sides pedal 11 it is back and forth swung up and down, fluted disc 4 is by continual driven in rotation, thereby realizes constantly moving ahead of bicycle, and people's pushes pedals 11 simulations action of running, and realized the purpose of taking exercises simultaneously.
