Embodiment
The characteristics of the utility model being further illustrated with reference to legend：
Specific embodiment one：Resistance occurring mode of the present utility model is that travelling gear 9 drives 10 turns of power transmission shaft when rotating
Dynamic, power transmission shaft 10 is rotated with dynamic crankshaft 7, and bent axle 7 is moved up and down by connecting rod 4 with piston 4-2, and the bottom of two oil cylinders 3 is
UNICOM, piston 4-2, which is moved up and down, causes the hydraulic oil in oil cylinder 3 to be flowed back and forth by oil cylinder unicom pipeline 11, oil cylinder UNICOM
The resistance trimming structure laid on pipeline 11 can change the internal diameter of oil cylinder unicom pipeline 11, so as to change liquid in oil cylinder unicom pipeline 11
The flow resistance of force feed.
Specific embodiment two：The utility model realizes the tangent line constant resisting force at the edge of travelling gear 9 by constant-resistance structure 5.
When piston in oil cylinder 3 is separately operable upper and lower stop, the rotary resistance of power transmission shaft 10 is minimum, now passes through constant-resistance structure 5
Constant-resistance piston 2-1 is pressed onto oil cylinder unicom pipeline 11 by constant-resistance elliptic wheel 2-4 major semiaxis with constant-resistance piston 2-1 axis coinciding
In, realize increase resistance to maximum.When piston in oil cylinder 3 runs to intermediate point, the rotary resistance of power transmission shaft 10 is maximum, now
Constant-resistance elliptic wheel 2-4 major semiaxis and constant-resistance piston 2-1 axis perpendicular, effects of the constant-resistance piston 2-1 in back-moving spring 2-3
Under, all withdrawn from from oil cylinder unicom pipeline 11, realize and reduce resistance to minimum.
Specific embodiment three：When the utility model is applied into body-building bicycle, it can select to remove constant-resistance structure 5 and transmission
Gear 9, the outside that pedal is arranged on bearing 6 are connected with power transmission shaft 10.Because movement structure of the people when pedaling body-building bicycle is
Determined by the running orbit of pedal, and people on the running orbit of pedal firmly be not uniform, bipod one is previous
When afterwards most beneficial for firmly, bipod one on the other when be least easy to have an effect.Structure of the present utility model just have maximum resistance and
The angle of minimum drag, it therefore, there is no need to constant-resistance structure 5 and travelling gear 9.
Specific embodiment four：, it is necessary to which the combination of constant-resistance structure 5 passes when the utility model is applied into reciprocal resistance
Moving gear 9, such as rowing machine, flat bench, in addition combination fitness setup drop-down, pedal and the movement structure such as stretch and can use this practicality
New structure, the utility model can provide uniform resistance during human body does work, and can essentially say it is with making
User's firmly changes and changes, and the resistance felt when user is done one's exercises using constant force is constant.The utility model is not
Limited by work distance, hardly limited by minimax resistance.
Specific embodiment five：Travelling gear 9 of the present utility model can use unidirectional resilient structures, so, be drawn using
When the reciprocating resistances such as ship device, can unidirectionally it exert oneself, opposite direction is not exerted oneself.
