A motion component 3 is arranged on the side of the seat cushion 21 away from the back cushion 22, that is, on the front side of the seat cushion 21. The motion component 3 includes two symmetrically arranged first swing frames 31. The first swing frames 31 are rotatably connected to the support frame 1, and the first swing frames 31 serve as the motion structure for the leg clamping action. A weight-bearing component 4 is arranged in linkage with the first swing frames 31. The weight-bearing component 4 includes a counterweight frame 41 for carrying the exercise weight. The counterweight frame 41 includes a barbell bar, and a barbell plate for counterweight can be placed on the barbell bar.

[0054] The support frame 1 includes a guide frame 12, which is arranged on the side of the back pad 22 away from the first swing frame 31. It is a vertically arranged rod guide structure; the first swing frame 31 and the counterweight frame 41 are linked, and the first swing frame 31 can drive the counterweight frame 41 to slide vertically along the guide frame 12.

[0055] The present invention utilizes a guide frame 12 coupled with a sliding counterweight frame 41 as the moving counterweight, with vertical sliding as the counterweight's trajectory. Compared to a swinging counterweight, this structure occupies less space, while providing no significant difference in motion performance. Furthermore, because the guide frame 12 serves as the guide, the counterweight exhibits greater stability during use, placing less strain on its supporting structure, compared to a swinging counterweight.

[0056] Based on the above embodiment, the support frame 1 further includes a base frame 11, a seat cushion frame 13 and a back cushion frame 14. The base frame 11 is the bottom structure of the support frame 1; the lower end of the guide frame 12 is fixedly connected to the base frame 11; the first swing frame 31 is rotatably connected to the base frame 11; the base frame 11 includes two parallel main bottom bars, and two cross bars are set between the main bottom bars.

[0065] On the basis of the above embodiment, the load-bearing assembly 4 further includes a linkage assembly, which is arranged between the first swing frame 31 and the counterweight frame 41. The first swing frame 31 can drive the counterweight frame 41 to rise or fall through the linkage assembly.

[0066] See also Figure 4The linkage assembly includes a secondary rotating rod 42 coaxially arranged with the main rotating rod 311, and the secondary rotating rod 42 is rotatably connected to the base frame 11. A rotating plate 43 is fixedly arranged on the circumference of the secondary rotating rod 42, and a plurality of adjustment holes are opened on the circumference of the rotating plate 43. An adjustment pin 44 is provided corresponding to the adjustment hole, and the adjustment pin 44 passes through the swing arm 312, and the adjustment pin 44 is plugged into the adjustment hole on the rotating plate 43. A rotating member 45 is connected to the rotating plate 43, and one end of the rotating member 45 is connected to the rotating plate 43; the other end is connected to one end of the rod body of the connecting rod 46. A second swing frame 47 is rotatably connected above the base frame 11, and the second swing frame 47 is connected to the end of the connecting rod 46 away from the rotating member 45. The linkage assembly also includes a pulley cable combination 48, one end of the cable of the pulley cable combination 48 is connected to the counterweight frame 41, and the other end is connected to the second swing frame 47.

[0067] This structure can realize the linkage between the swing arm 312 and the counterweight frame 41. And because the initial position of the swing arm 312 needs to be adjusted according to the demand, that is, Figure 5 and Figure 6 In order to facilitate adjustment, the present invention provides an adjustment pin 44 and a rotating plate 43, which can change the initial position of the swing arm 312 by simply plugging and rotating.

[0068] On the basis of the above implementation scheme, the specific connection form of the rotating plate 43, the rotating member 45, the connecting rod 46 and the second swing frame 47 can be realized in various forms. This solution provides the following two forms.

[0069] One approach involves a rotatably connected end of the connecting rod 46 to the side of the second swing bracket 47, with their respective rotation axes being horizontal. Alternatively, the connecting rod 46 is rotatably connected to the rotating member 45, with their respective rotation axes being vertical. The rotating member 45 is rotatably connected to the rotating plate 43, with their respective rotation axes also being vertical. In this case, the connection between the connecting rod 46 and the rotating member 45, or the connection between the rotating member 45 and the rotating plate 43, must also be vertically slidable.

[0070] Another is that both ends of the connecting rod 46 and the second swing frame 47 and the rotating member 45 are all connected by ball joints, and the rotating member 45 and the rotating plate 43 are rotatably connected, and the rotation axis directions of the two are vertical.

[0071] Both of the above forms can achieve the linkage effect required by this solution.
