Description
Technical field
The utility model relates to a kind of rotary pulling force device technical field of utilizing pulling force and inertia, specifically refers to a kind of rotary pulling force device of scalable moment.
Background technology
Along with carrying out of national body building comprehensively, people need more pulling force equipment to take exercises.The exercise chest that adopts at present and the equipment of arm strength mainly are steel strand exercisers; This steel strand exerciser is that the extension spring active card by regular length and elastic force is contained on the handle, and the person taking exercise grasps handle, exercises one's muscles by the pulling force that overcomes extension spring; But this chest expander is owing to the natural length and the deformation length of extension spring immobilize; The adjusting of pulling force is to rely on the quantity of increase and decrease extension spring to adjust, just pulling force almost at double adjustment change, chest expander pulling force extent can not well be adjusted.
The utility model content
The technical problem that the utility model will solve provides a kind of rotary pulling force device of scalable moment, solves the technical problem that existing chest expander pulling force extent can not well be adjusted, the technical problem of convenient adjustment chest expander moment size.
For solving the problems of the technologies described above; The utility model adopt technical scheme be: a kind of rotary pulling force device of scalable moment; Comprise flywheel central shaft, symmetry be fixedly mounted on pulling force rope on the flywheel central shaft of the disc type flywheel of flywheel central shaft both sides, front end sleeve, connect the pulling force rope rear end the pulling force rope handle and outside cover on the housing outside the disc type flywheel; Bearing fixing is passed through on housing in flywheel central shaft two ends; The right side of housing has can be through the rope hole of pulling force rope; The center line in rope hole also passes through the mid point of flywheel central shaft perpendicular to the flywheel central shaft; The left side of housing is provided with the housing handle that is fixed on the housing with the rope hole site along the mirror image of flywheel central axis symmetry place, and the pulling force rope handle is arranged on the right hand external of housing, and described disc type flywheel comprises two blocks of flywheel plates and the balancing weight that is fixed on flywheel central shaft both sides; Be furnished with a plurality of balancing weight mounting grooves that mate with balancing weight on the flywheel plate outer face, a plurality of balancing weight mounting grooves are that central point carries out the multi-layer annular array with the flywheel central shaft.
Adopt the chest expander of technique scheme; During use, use the external force rotary middle spindle, pulling force rope is twisted in pulling force rope on the flywheel central shaft along counter clockwise direction; Left hand is held the fixedly housing handle of chest expander; The pulling force rope handle that the right hand is held the right side outwards pulls at pulling force rope, and at this moment, pulling force rope can drive the disc type flywheel and turn clockwise; Then, user's right arm inwardly moves, under the effect of inertia of disc type flywheel; Pulling force rope is turned clockwise rollback again to the flywheel central shaft; At this moment, the right hand is outwards firmly expanded once more and is drawn pulling force rope, and pulling force rope can drive the disc type flywheel again and be rotated counterclockwise; So back and forth operation has just formed the back and forth motion exercise of outer expansion.It is the same that the reciprocal motion principle of rotary pulling force device of this scalable moment is similar to yo-yo, and the principle of utilizing object of which movement can produce inertia realizes.When outside when drawing pulling force rope, flywheel rotates.According to the size of pulling force, the speed that flywheel rotates is also different, and the size of inertia force is also different, and flywheel rotates fast more, and inertia force is big more.When pulling force rope is pulled out, flywheel will be rotated further along the former direction of motion because of the cause of inertia, in the time of motion pulling force rope regained and will be wrapped on the flywheel central shaft, and people's hand pulls at pulling force rope slows down flywheel.When flywheel stops operating or reaches capacity because of people's hand pulling force after the position stops operating, people's hand is firmly pulled out pulling force rope once more, makes the flywheel counter motion.Thus at people's hand pulling force, under the effect of flywheel inertia force, constantly repetitive operation reaches the purpose of body-building.Limit described disc type flywheel and comprise two blocks of flywheel plates and the balancing weight that is fixed on flywheel central shaft both sides; Be furnished with a plurality of balancing weight mounting grooves on the flywheel plate outer face with the balancing weight coupling; A plurality of balancing weight mounting grooves are that central point carries out the multi-layer annular array with the flywheel central shaft; The qualification of this structure can guarantee to adjust as required the quality and the moment of flywheel, and set-up procedure is mainly to be opened housing earlier, balancing weight is snapped onto in the balancing weight mounting groove of flywheel plate outer face; After regulating counterweight, housing closed to fix.Through installation site and quantity, the quality of adjustment balancing weight, also just adjusted the size of flywheel rotating inertia force like this, flywheel moment is big more, and inertia force is big more.Can be suitable for crowd's demand and the requirement that rank are entered in exercise according to difference, adjust the moment of flywheel voluntarily.
This technical scheme is different from common steel strand exerciser.Ball spring structure chest expander, elastic pulling force is constant, and the user need choose the steel strand exerciser of different size elastic force according to self strength size, and spring has fatigue effect, and long-time frequent use can make its distortion.Because entire mechanism does not have spring structure, just there is not constant pulling force restriction yet, the flywheel velocity of rotation is fast more, and is big more in the inertia, and the pulling force of generation is also just big more.Otherwise velocity of rotation is more little, and the pulling force of generation is also just more little, and pulling force can in very large range carry out electrodeless adjusting, and the user can adjust the pulling force size according to self-demand fully, and the utility model use have certain recreational, all-ages.Common in addition rotary pulling force fitness equipment, flywheel moment is constant, and the user need choose the different size chest expander according to self strength size.The advantage of this structure is, only needs a cover fitness equipment main body mechanism, and cooperation can change the counter-weight flywheel annex of quality and moment, does not also just exist the moment size to receive the restriction of flywheel mass, and flywheel mass is big more, and inertia force is big more, and the pulling force of generation is also just big more.Otherwise flywheel mass is more little, and the inertia force of generation is also just more little, and the moment that flywheel produces can be regulated through the counterweight that increases or reduce flywheel, and the user can adjust the pulling force size according to self-demand fully.
Further, symmetry processing for ease, limiting described multi-layer annular array is five layers, the balancing weight mounting groove on the individual layer is an angle of 90 degrees at interval.
