Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
In description of the present utility model, it should be noted that, term "front", "rear", " on ", the orientation of the instruction such as D score, "left", "right" be normal use body-building bicycle time, relative to user, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
See Fig. 1-Figure 10, it is an embodiment of the body-building bicycle that the utility model proposes, a kind of body-building bicycle comprises vehicle frame 1, vehicle frame 1 is provided with handlebar 2, trailing wheel 3, two can pedal 4, two messenger chains 5 of up-and-down movement, namely be provided with two pedals 4 in left and right and two, left and right messenger chain 5, two backgears 6 be meshed with two messenger chains 5 are respectively provided with at trailing wheel 3 place, when pedal 4 moves downward, pedal 4 compresses messenger chain 5, makes backgear 6 drive trailing wheel 3 to rotate forward.
In the present embodiment, by arranging pedal 4 and messenger chain 5, when pedal 4 moves downward, pedal 4 compresses messenger chain 5, the messenger chain at backgear 6 place is moved forward, and then drives the backgear 6 engaged with messenger chain 5 to rotate forward, trailing wheel 3 is also followed backgear 6 and is rotated forward.Like this by the up-and-down movement of pedal 4, achieve the rotation forward of trailing wheel 3, make the drive actions of body-building bicycle fairly simple, only need with the downward pedal 4 of pin, easy to learn; And by the alternately knee-action of two foot pedals 4, achieve the object of body-building and leg exercising muscle.
In the present embodiment, shown in Fig. 1 and Fig. 2, vehicle frame 1 is provided with two front gears 7 be connected with two messenger chains 5 respectively, and front gear 7 is the one-way wheel rotated forward; Make front gear 7 to rotate forward like this, can not rotate backward, the messenger chain 5 being namely positioned at front gear 7 place can not move backward.Arrange backgear 6 to be real-turn forward, to dally backward simultaneously, drive trailing wheel 3 to rotate when namely backgear 6 rotates forward, dally when backgear 6 rotates backward, namely do not drive trailing wheel 3 to rotate backward.Pedal 4 is positioned at the top of gypsy chain 5, make when pedal 4 compresses messenger chain 5 so downwards, the messenger chain 5 at pedal 4 place has the trend moved downward, because front gear 7 is the one-way wheel rotated forward, thus can only move forward by the messenger chain at backgear 6 place the tension force realized on whole messenger chain 5 identical; Namely the messenger chain at backgear 6 place drives backgear 6 to move forward, and then gives trailing wheel 3 power forward, and trailing wheel 3 is rotated.
In order to increase the distance that messenger chain 5 moves down under pedal 4 acts on, and then the distance that the messenger chain 5 at backgear 6 place is moved forward increases, and makes backgear 6 drive trailing wheel 3 anglec of rotation also larger; Messenger chain 5 is provided with expansion tightening wheel 8, and when pedal 4 compresses messenger chain 5, the tensile force of messenger chain 5 increases, and make expansion tightening wheel 8 stressed and regain mobile, now the messenger chain 5 at expansion tightening wheel 8 place moves to pedal 4 place through backgear 6; Messenger chain 5 is through backgear 6 in the process of pedal 4 place's movement, and messenger chain 5 drives backgear 6 to rotate forward, and then drives trailing wheel 3 to rotate forward.When such two pin are alternately to lower pedal 4, the power making two backgears 6 in left and right alternately give trailing wheel 3 to rotate forward, makes trailing wheel 3 rotate.
In embodiments more of the present utility model, transverse axis 11 before vehicle frame 1 is fixedly installed, two front gears 7 are separately positioned on the left and right sides of front transverse axis 11.Expansion tightening wheel 8 is arranged on vehicle frame 1, also can be arranged on front transverse axis 11.
For the concrete structure at pedal 4 place, multiple implementation can be had, shown in Figure 4, for a kind of embodiment at pedal 4 place, pedal 4 is provided with the article 41 of vertical direction, be provided with former and later two pinch rollers 42 in the lower end of article 41, and on pinch roller 42, be provided with the gear teeth matched with messenger chain 5, two pinch rollers 42 engage with messenger chain 5; By arranging pinch roller 42, when ensure that pedal 4 moves downward, the transmission of power between pedal 4 and messenger chain 5, makes to act on power on pedal 4 by vertical the acting on messenger chain 5 of article 41.
Vehicle frame 1 is provided with former and later two pinch wheels 12 contacted with article 41, gives the grip force that article 41 is certain; Like this article 41 at up-and-down movement time, move between two pinch wheels 12.As shown in Figure 5, for the cutaway view of the axis along pinch wheels 12, vehicle frame 1 is fixed with vertical plate 14, pinch wheels 12 is arranged on vertical plate 14 by axle, at the right and left of vertical plate 14, two pinch wheels 12 are respectively set, the wheel face of pinch wheels 12 is set to the cambered surface of indent, and the rear and front end of article 41 is provided with the cambered surface of evagination, and the front/rear end of article 41 contacts with the wheel face of two pinch wheels 12 respectively.Be provided with the limiting stopper 411 matched with pinch wheels 12 in the lower end of article 41, when article 41 upwards reset put in place time, the limiting stopper 411 of article 41 lower end contacts with pinch wheels 12, restriction article 41 continue to move up.
In the present embodiment, the T-shaped structure that article 41 and pedal 4 are integrated, article 41 is set to arcuate structure with the connecting portion 412 of pedal 4, when pedal 4 move downward put in place time, connecting portion 412 contacts with pinch wheels 12, and pinch wheels 12 block pedal 4 continues to move downward, and plays position-limiting action.
Wherein, article 41 can be set to oblate cylindricality or cylindrical etc., can arrange extension spring between article 41 and vehicle frame 1, increases elastic force.
