Consult
fig. 1shown in, a kind of body-building apparatus provided by the invention, comprise support 1, be placed in the resistance generating apparatus on support 1, support 1 comprises two supports be oppositely arranged 11, and resistance generating apparatus comprises the main shafts 2 be located in two supports 11, be placed in the ratchet device 3 on main shaft 2, when main shaft 2 rotates forward drive ratchet device 3 rotate, during reverse rotation and ratchet device 3 depart from, also comprise the rubbing device 4 for providing frictional resistance for ratchet device 3 be connected with support 1.Drive main shaft 2 to rotate forward during body builder's body-building action, main shaft 2 is meshed with ratchet device 3 and drives ratchet device 3 to rotate, and rubbing device 4 provides frictional force for ratchet device 3.
Concrete, ratchet device 3 comprises and to be sheathed on main shaft 2 and with main shaft 2 with dog end 31, in order to improve the stability of main shaft and make main shaft uniform force, the centre position of main shaft 2 is located at by this ratchet 31, ratchet 31 is internal tooth ratchet, relative with this ratchet 31 internal tooth position and hinged with main shaft 2 bias ratchet 32, this ratchet 32 has the position of engagement be meshed with the internal tooth on ratchet 31 and detaches the disengaging configuration of internal tooth, is also provided with one for ratchet 32 being repositioned to the torsion spring 35 of the position of engagement between ratchet 32 and main shaft 2.Utilize ratchet 32 and ratchet 31 to coordinate, only when main shaft 2 rotates forward, the ratchet 32 on main shaft 2 engages with ratchet 31, drives ratchet 31 to rotate, and when main shaft 2 reversely rotates, ratchet 32 and ratchet 31 depart from.
Preferably, ratchet device 3 also comprises a terminal pad 33 be connected with ratchet 31, and the position that terminal pad 33 is relative with ratchet 31 axis is provided with a terminal pad through hole, and terminal pad through hole is connected with main shaft 2 by a bearing, this terminal pad 33, for carrying out spacing to ratchet 31, prevents ratchet about 31 from collecting together.Ratchet device 3 also comprises a back-up block 34 be connected with support 1, this back-up block 34 has a notch matched with ratchet 31 profile, and the notch of back-up block 34 is installed on the cylindrical of ratchet 31 bottom.
In the present invention, rubbing device 4 comprises a fricting strip 41 matched with ratchet 31, one end of fricting strip 41 is connected with one end of back-up block 34, the other end that fricting strip 41 walks around ratchet 31 is connected with the other end of back-up block 34 is adjustable, this end can by screw thread or the pressure force between pad adjustment ratchet 31 and fricting strip 41, when body builder needs different resistances, only need regulate screw thread or regulate pad quantity just can change the size of frictional resistance.Rubbing device 4 also can be a screw, and the side of notch is provided with a screwed hole, and screw is arranged in screwed hole the side of pushing up main ratchet 31, the size of the size of adjustment screw screwing force and the frictional resistance between adjustable ratchet 31 and screw.
Main shaft 2 is wound with a drag-line 12, is provided with a mousing-hook 13 in the end of drag-line 12.Optimum, drag-line 12 has 2, is wound in respectively on the outside main shaft 2 of two supports 11.Body builder can drive main shaft 2 to rotate forward by pulling mousing-hook 13, and ratchet 32 engages with ratchet 31, and drive ratchet 31 to rotate, rubbing device 4 produces friction resistance force and is passed in mousing-hook 13, reaches the object of body builder's body-building.This mousing-hook 13 also can be hooked to other in order on the additional mechanism providing additional operation of body-building, in order to the pulling force of drag-line 12 is changed over other motion modes, as pull bar, push rod etc.
Main shaft 2 is also provided with one for described main shaft 2 being returned back to the drag-line rewinding device 5 of initial position.Preferably, drag-line rewinding device 5 has 2, is placed on the main shaft 2 of ratchet device 31 both sides.Concrete, this drag-line rewinding device 5 comprises one and is set in scroll spring on described main shaft 2, this drag-line rewinding device 5 also can be one be wrapped in elastic rubber band on main shaft 2, mousing-hook 13 is pulled during body builder's body-building, drag-line 12 is drawn out, main shaft rotates forward, the pulling force of rubber strip is utilized to return back to initial position by being drawn the main shaft 2 of rotation by body builder, drag-line 12 is driven again to be wound around main shaft 2 again to pull drag-line 12 body-building, and because ratchet when main shaft 2 reversely rotates 31 and ratchet 32 depart from, so main shaft 2 can be retracted initial position by minimum turning power.
Ratchet 31 both sides on main shaft 2 are also equipped with a scroll spring, and this scroll spring resets for making the main shaft 2 rotated forward reversely rotate, and is again wound around drag-line 12.When main shaft 2 resets, ratchet 32 and ratchet 31 depart from, and the frictional resistance that rubbing device 4 acts on ratchet 31 can not be passed on main shaft 2, so utilize very little screen resilience that main shaft 2 can be made again to reset.
Support 1 is also provided with a seat 14, the support 1 of seat 14 both sides is respectively provided with a vertical rod 15, the upper and lower end of each vertical rod 15 is equipped with the first pulley 16, and the support 1 being positioned at seat 14 front end is also provided with the second pulley 17.In use, by guy cable rounds first pulley 16 or the second pulley 17, can change the direction that mousing-hook 13 pulls, meet the difference of the power thrusts required for different action.The first pulley 16 on support 1 also can be directly installed on below seat 14 and changes athletic posture to facilitate and save space.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
