Among the figure: 1 bicycle, 2 handlebars, 3 support arms, 4 connecting rods, 5 drive sprockets, 6 chains, 7 flywheels, 8 turning sets, 9 location clamping arms, 10 unidirectional rotation cams, 11 guiding tension wheels, 12 crossbeams, 13 pinch rollers, 14 holddown springs, 15 position-limited levers, 16 bearings, 17 turning cylinders, 18 fixed covers, 19 anchor shafts, 20 front vehicle forks, 21 bent axles, 22 spring pivot shafts.

The specific embodiment

The utility model is described in further detail to utilize drawings and Examples below.

With reference to Fig. 1～4, the manual power-assisted fitness equipment of bicycle of the present utility model is connected with existing bicycle 1, also can be connected with three-wheel vehicle.The manual power-assisted fitness equipment of bicycle is that the lower end of handlebar 2 and crossbeam 12 and turning set 8 are connected, and turning set 8 is contained on the anchor shaft 19 of bearing 16, and bearing 16 is connected with front vehicle fork 20.Be fixed with support arm 3 on the crossbeam 12, the front end of support arm 3 and connecting rod 4 upper ends are hinged, and the lower end of connecting rod 4 and bent axle 21 are hinged, and bent axle 21 is connected with unidirectional rotation cam 10.In the fixed cover 18 of bearing 16 turning cylinder 17 is housed, unidirectional rotation cam 10 and drive sprocket 5 are packed in the two ends of turning cylinder 17.Location clamping arm 9 is housed on the spring pivot shaft of putting on the bearing 16 22, is nested with holddown spring 14 on spring pivot shaft 22, an end of holddown spring 14 contacts with bearing 16, and the other end of holddown spring 14 hangs on the position-limited lever 15 that is provided with on the clamping arm 9 of location.Location clamping arm 9 front end pivotally attached pinch rollers 13 contact with the flange of unidirectional rotation cam 10.The drive sprocket 5 that turning cylinder 17 installs is connected with the flywheel of installing on the bicycle front axle 7 by chain 6.The guiding tension wheel 11 that is provided with on front vehicle fork 20 is used to adjust tension chain 6.

With reference to Fig. 1 and 5, when using the manual power-assisted fitness equipment of bicycle of the present utility model, holding handlebar 2 pushes away forward, handlebar 2 makes the turning set 8 that is connected with handlebar 2 rotate counterclockwise around anchor shaft 19, the crossbeam 12 that handlebar 2 is connected deflects down the support arm 3 that is connected on the crossbeam 12, support arm 3 pivotally attached connecting rods 4 drive bent axle 21 and rotate, the unidirectional rotation cam 10 that bent axle 21 is connected rotates counterclockwise, unidirectional rotation cam 10 and drive sprocket 5 are packed in the two ends of turning cylinder 17, make drive sprocket 5 drive by chain 6 that the flywheel of installing 7 rotates on the bicycle front axle and the auxiliary power driven vehicle wheel moves ahead; Make handlebar 2 by preceding pulling back again, handlebar 2 makes the turning set 8 that is connected with handlebar 2 clockwise rotate around anchor shaft 19, the crossbeam 12 that handlebar 2 is connected upward deflects the support arm 3 that is connected on the crossbeam 12, but the flange that under the effect of holddown spring 14, presses unidirectional rotation cam 10 because of location clamping arm 9 front end pivotally attached pinch rollers 13 all the time, force unidirectional rotation cam 10 to continue to rotate counterclockwise, make drive sprocket 5 drive by chain 6 that the flywheel of installing 7 rotates on the bicycle front axle and the auxiliary power driven vehicle wheel moves ahead, back and forth before, back push-and-pull vehicle realizes that continuous auxiliary power driven vehicle wheel moves ahead to 2.Hold in the process of handlebar 2 reciprocal forward and backward push-and-pulls, human body seesaws, and the arm song is stretched motion, therefore, not only can make the car power-assisted, can also promote the dynamics of human motion, makes body-building effect better.Because the manual power-assisted fitness equipment of bicycle is connected by bearing 16 and front vehicle fork 20, so that bicycle turns to is identical with existing bicycle, three-wheel vehicle.
