As shown in fig. 10, the first rope 25, the second rope 282, the third rope 389, and the fourth rope 49 enter the frame body 51, are collectively turned by the fixed pulley to the top of the frame body 51, and are extended downward by the turning of the positioning wheel, and a coiler 6 is provided at each of the tail portions of the first rope 25, the second rope 282, the third rope 389, and the fourth rope 49, and are connected to the counterweight 5 by the coiler 6.

Due to the adoption of one set of counterweight device 5, one of the fitness equipment back and arm training device 2, the leg training device 3 and the chest and shoulder training device 4 can only meet the requirement at the same time, and the counterweight device 5 is used by the rest devices, so that the multifunctional fitness equipment is convenient to use for high-end single apartments or independent people. However, when the counterweight device 5 is operated by pulling the first rope 25, the second rope 282, the third rope 389, and the fourth rope 49 are loosened, and the corresponding ropes are likely to be separated from the positioning wheels, so that the winder 6 can be provided to solve such a problem.

As shown in fig. 10, a connecting plate 61 fixed to the vertical shaft is vertically disposed between the two vertical shafts 52, the connecting plate 61 is located at one third of the vertical shaft 52 near the upper end, four sliding slots 611 are vertically disposed on the connecting plate 61, and the four sliding slots 611 are arranged at equal intervals.

As shown in fig. 11 and 12, the winding device 6 includes a weight seat 62, a sliding block 621 is fixed to one side of the weight seat 62, the sliding block 621 is located in the corresponding sliding slot 611 and slidably connected to the connecting plate 61 along the length of the sliding slot 611; an extension plate 63 is fixedly connected to one side of the counterweight seat 62, which is far away from the sliding block 621, a screw 64 is horizontally and fixedly connected to one side of the extension plate 63, the screw 64 is horizontally arranged, a rotary drum 65 is sleeved on the screw 64, and an internal thread in threaded fit with the screw 64 is formed in the inner circumferential surface of the rotary drum 65; an auxiliary pull wire 66 is arranged on the circumferential surface of the rotary drum 65, one end of the auxiliary pull wire 66 is fixedly connected with the rotary drum 65, and the other end of the auxiliary pull wire 66 is fixed on the driving plate 54; the length of the drum 65 is longer than that of the screw 64, so that when the screw 64 is flush with one end of the drum 65, a vacant space is left in the drum 65; a positioning shaft 67 is coaxially arranged in the rotary drum 65, the diameter of the positioning shaft 67 is smaller than that of the screw 64, and the end part of the positioning shaft 67 is fixed at the end part of the screw 64; the cover is equipped with a torsional spring 68 on the location axle 67, the tip at screw rod 64 is fixed to the one end of torsional spring 68, and still be fixed with two stopper 69 to the torsional spring 68 other end is spacing in the rotary drum 65, two stopper 69 are located the both sides of torsional spring 68 tip, when making rotary drum 65 rotate relatively with screw rod 64, stopper 69 not only can drive torsional spring 68 elastic deformation, and along with the produced displacement of rotary drum 65, stopper 69 can produce the relative slip with the tip of torsional spring 68, nevertheless can not break away from with torsional spring 68 tip, thereby ensure that the elastic force of torsional spring 68 can transmit on rotary drum 65 constantly.

As shown in fig. 11, a limiting column 60 is further fixedly connected to a side of the extension plate 63 facing the screw 64, the limiting column 60 is disposed near the screw 64, and an arc notch 651 is opened on an end surface of the drum 65 facing the limiting column 60. When the drum 65 is rotated and displaced toward the extension plate 63, the position-limiting post 60 is gradually located in the notch 651 and abuts against the end of the notch 651, so that the screw 64 and the drum 65 are limited from continuously rotating. The end portions of the first rope 25, the second rope 282, the third rope 389, and the fourth rope 49 are fixed to the corresponding weight holders 62.

When the winding device 6 is in the initial state, the auxiliary pulling rope 66 is in a tensioned state, the sliding block 621 is positioned at the bottom of the sliding groove 611, the limiting column 60 is positioned in the notch 651, the torsion spring 68 is in the maximum rebound position, and the first pulling rope 25, the second pulling rope 282, the third pulling rope 389 and the fourth pulling rope 49 are pulled by the corresponding counterweight seat 62 and keep in a tensioned state. When the counterweight device 5 is pulled by the first rope 25, the slider 621 and the connecting plate 61 are slid, and the auxiliary rope 66 pulls the driving plate 54 to lift the counterweight block 53. Because the limiting column 60 is located in the opening 651, the continuous rotation of the rotary drum 65 and the screw 64 can be limited, the torsion spring 68 is located at the position with the maximum resilience force and is acted by the tension of the counterweight 53, the torsion spring cannot rotate, and the stress of the torsion spring 68 is reduced due to the limitation of the limiting column 60 and the opening 651, so that the torsion spring 68 is not easily damaged. Because the counterweight 53 rises, the auxiliary stay wires 66 of the other winding devices 6 are in a loose state, at this time, the corresponding torsion springs 68 enable the drum 65 to only receive the elastic acting force of the torsion springs 68 due to the reduction of the pulling force of the auxiliary stay wires 66, and drive the drum 65 to rotate towards the direction of the screw 64, so as to drive the auxiliary stay wires 66 to wind around the circumferential surface of the drum 65, so that the other loose auxiliary stay wires 66 are not easy to be wound together, the second stay ropes 282, the third stay ropes 389 and the fourth stay ropes 49 are not separated from the corresponding fixed pulleys, and the working stability of the body-building apparatus is ensured. When the weight 53 returns to its original position, the auxiliary wire 66 is pulled away from the drum 65, and the drum 65 and the screw 64 rotate relative to each other, so that the torsion spring 68 is in the maximum working state.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
