Rope is wrapped in the intermediate cylindrical surface and end is fixed, and is also reeved on first fixed pulley, and the steel wire rope is successively
Through second fixed pulley, the 3rd fixed pulley, then wound from outside to inside before last end is fixed on along the spiral bar
Hold in the rotating shaft of plectane.
Further, front end plectane is also stamped end cap, and the end cap central is provided with circular hole, then passes through on the plectane of front end
Rotating shaft is simultaneously fastened on the plectane of front end.
The beneficial effects of the utility model are：In the utility model, in the strengthening exercise starting stage, just start steel wire rope
The arm of force be d2, it is d that the arm of force of balancing weight is constant, thus steel wire rope gravity of the pulling force less than balancing weight, facilitate user to pull
Balancing weight, then in drawing process, the arm of force of steel wire rope is gradually reduced, and the pulling force of steel wire rope gradually increases, until user without
Untill method is pulled on, thus user substantially without increase and decrease balancing weight, can according to the strength of oneself pull certain distance until
Cannot pull, using more convenient, also more train on.
Brief description of the drawings
Fig. 1 is the structure chart of the body-building apparatus counter-balanced carriage that the utility model embodiment is provided；
Fig. 2 is the structure chart of power transmission shaft.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation
Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model, is not used to limit the utility model.
In order to illustrate technical scheme described in the utility model, illustrated below by specific embodiment.
As shown in Figure 1, 2, the body-building apparatus that the present embodiment is provided counter-balanced carriage includes framework 1, and the bottom of the framework 1 is installed
There is the first fixed pulley 11, the frame roof has also installs two in the second fixed pulley 12 and the 3rd fixed pulley 13, the framework 1
There is vertical guide rod 2, intermediate draw bar 3 is additionally provided with the middle of two vertical guide rods 2, being provided with some pieces on the vertical guide rod 2 matches somebody with somebody
Pouring weight 4, all balancing weights 4 are through on the intermediate draw bar 2, and both sides are respectively welded with one before and after the counter-balanced carriage centre position
Support bar 5, is provided with power transmission shaft 6 between two support bars 5, the power transmission shaft 6 includes intermediate cylindrical 61, the intermediate cylindrical 61
Front side be front end plectane 62, the rear side of intermediate cylindrical is rear end plectane 63, and two blocks of plectanes are coaxial with intermediate cylindrical, and diameter is big
