The second hanging part 410 has a long shaft structure and can be directly inserted into the center hole of the counterweight 700.

[0032] The first mounting portion 330 and the second mounting portion 410 are spaced apart in the horizontal direction, with the first mounting portion 330 close to the seat 200 and the second mounting portion 410 away from the seat 200.

[0033] The fitness equipment also includes a foot pedal 500, which is mounted on the first swing frame 300. The foot pedal 500 is located above the first swing frame 300, and a first hanging part 330 is located below it. When the user lies on the seat 200, he pushes his feet up against the foot pedal 500, causing the first swing frame 300 to swing up and down, which in turn causes the second swing frame 400 to swing up and down.

[0034] The fitness equipment in its first working mode, refer to Figure 5 and Figure 6 Counterweights 700 are mounted on both the first mounting part 330 and the second mounting part 410. Figure 5 It is the starting position. Figure 6 This is the ending position. As shown in the diagram, as the foot pedal 500 swings upward, the lower end of the first swing frame 300 swings upward, causing the counterweight 700 on it to move upward; the front end of the second swing frame 400 (the end furthest from the seat 200) swings upward, causing the counterweight 700 on it to move upward. Figure 5 Location reached Figure 6 Location.

[0035] In the second working mode, refer to Figure 7 and Figure 8The first mounting part 330 has a counterweight plate 700 mounted on it, while the second mounting part 410 is empty. Figure 7 It is the starting position. Figure 8 This is the ending position. As shown in the diagram, as the foot pedal 500 swings upward, the lower end of the first swing frame 300 swings upward, causing the counterweight 700 on it to move upward.

[0036] In the third working mode, refer to Figure 9 and Figure 10 The first mounting part 330 is empty, and the second mounting part 410 has a counterweight 700 mounted on it. Figure 9 It is the starting position. Figure 10 This is the ending position. As shown in the diagram, as the foot pedal 500 swings upward, the front end of the second swing frame 400 swings upward, causing the counterweight 700 on it to move upward. Figure 9 Location reached Figure 10 Location.

[0037] The fitness equipment of this application is equipped with multiple hanging parts for hanging weight plates 700. By hanging weight plates 700 of different weights on different hanging parts, the weight plates 700 can be hung on a single hanging part or multiple hanging parts, realizing a variety of experiences with single hanging points and combined hanging points, providing users with a more comfortable training experience and meeting the needs of different user groups.

[0038] Existing weight-bearing fitness equipment uses only a single hanging part, resulting in a fixed hanging position for the weight plate 700. Users can only adjust the training load by adding or removing weight plates 700, but cannot change the position of the lever arm applied by the weight or the force transmission path. This leads to a monotonous training experience and fails to meet diverse training needs. This application constructs a multi-hanging point weight system by setting a first hanging part 330 and a second hanging part 410 on the first swing frame 300 and the second swing frame 400, respectively, with the two hanging parts distributed at intervals in the horizontal direction (the first hanging part 330 is closer to the seat 200, and the second hanging part 410 is farther away from the seat 200). With the flexible switching between three working modes, users can choose different combinations of hanging parts according to their training goals: In the first working mode, both hanging parts simultaneously hang weight plates 700, forming a compound load transmission through the superposition of lever arms, thus enhancing training intensity; in the second working mode, only the first hanging part 330 on the side closest to the seat 200 is used, shortening the lever arm length and reducing the difficulty of exertion, suitable for beginner training or muscle endurance training; in the third working mode, only the second hanging part 410 on the side furthest from the seat 200 is used, extending the lever arm length and improving the training effect of muscle explosive power. This multi-dimensional weight combination method breaks the limitations of the single training sensation of traditional fitness equipment, achieving full-scene coverage from basic strength training to advanced explosive power training, and meeting the diversified experience of different training stages and different training needs.

[0039] The single-weight structure of existing fitness equipment cannot meet the needs of users with different heights and fitness levels, resulting in some users experiencing reduced training effectiveness due to unsuitable force application angles and insufficient load adjustment range. This application solves this problem through a dual-adaptation design. On the one hand, the seat 200 has backrest angle adjustment and fore-aft position adjustment functions, which can optimize the relative position of the body and the equipment for users of different heights, ensuring proper force application posture. On the other hand, the multi-hanging weight adjustment method provides a more precise load gradient. For example, beginners with weaker fitness can choose the second working mode, using the short lever arm weight of the first hanging part 330 to lower the force application threshold; professional fitness enthusiasts can use the first working mode, using the combined weight of the two hanging parts to achieve high-intensity training; for specific muscle group training needs, the long lever arm weight of the third working mode can also be used to precisely enhance the force application efficiency of the target muscles. In addition, the weight plate 700 can flexibly combine different weights in one or more hanging parts, further expanding the load adjustment range. Whether it is teenagers, adults, or middle-aged and elderly users, they can find a training program suitable for their own fitness level, significantly improving the universality of the equipment.

[0040] Traditional single-weight fitness machines, due to their fixed force transmission path, are prone to uneven muscle stress over long-term training, leading to fatigue or sports injury risks. Furthermore, the monotonous training modes can reduce user motivation. This application achieves adjustable training sensation through optimized mechanical structure of multiple mounting parts. Specifically, when different working modes are used, the movement trajectory and lever arm length of the weight plate 700 change, making the muscle exertion process more in line with the laws of human biomechanics, reducing excessive load on local muscles, and lowering the probability of sports injury. For example, the long lever arm design in the third working mode can distribute the pressure at the point of force application, preventing excessive tension on a single muscle group; the first working mode with dual mounting parts enables coordinated force application from multiple muscle groups, improving training comfort and effectiveness. At the same time, diverse training modes provide users with a wealth of fitness options, avoiding the boredom of long-term monotonous training and helping to improve fitness persistence. In addition, the weight plate 700 is stably installed through the long-axis structure of the mounting parts, making it less likely to fall off during exercise. Combined with the stable support design of the fixing frame 100, this further ensures safety during use.

[0041] In some embodiments of this application, a first hanging part 330 is provided on each of the opposite sides of the first swing frame 300. The first hanging part 330 is located on the left and right sides of the upright frame 120.

[0042] The connecting frames 600 are rotatably mounted on opposite sides of the first swing frame 300, and the connecting frames 600 are located on the left and right sides of the upright frame 120. Each of the connecting frames 600 is rotatably connected to the second swing frame 400.

[0043] Reference Figure 4 The rotational connection position between the first swing frame 300 and the fixed frame 100 is the second rotational position, denoted as P2. The line connecting the first hanging part 330 and the second rotational position P2 is the first connecting line, denoted as X1, and the angle between the first connecting line X1 and the ground is the first angle, denoted as β.

[0044] The rotational connection position between the second swing frame 400 and the fixed frame 100 is the fourth rotational position, denoted as P4. The line connecting the second hanging part 410 and the fourth rotational position P4 is the second line, denoted as X2, and the angle between the second line X2 and the ground is the second angle, denoted as γ.

[0045] The rotational connection position between the connecting frame 600 and the second swing frame 400 is the third rotational position, denoted as P3. The rotational connection position between the connecting frame 600 and the first swing frame 300 is the first rotational position, denoted as P1.

[0046] The first included angle β is different from the second included angle γ, which results in different vertical downward force components during movement when the weight plate 700 is hung on the first hanging part 330 and the second hanging part 410. The two hanging points can hang the weight plate 700 individually or simultaneously to achieve multiple combinations of weights and thus achieve different training sensations.

[0047] In some embodiments of this application, reference is made to Figures 1 to 3 The fixing frame 100 includes a first connecting rod 130. Specifically, the upright frame 120 includes a first connecting rod 130, which extends horizontally and is perpendicular to the front-back movement direction of the seat 200.

[0048] The first swing frame 300 includes two first sub-swing frames 310 arranged left and right. The two ends of the first connecting rod 130 are rotatably connected to the first sub-swing frames 310 respectively. Each of the first sub-swing frames 310 is provided with a first hanging part 330. The foot pedal 500 is disposed between the two first sub-swing frames 310.

[0049] The rotatable connection between the first connecting rod 130 and the first sub-swing frame 310 is located in the middle of the first sub-swing frame 310, while the foot pedal 500 and the first hanging part 330 are located on the upper and lower sides of the first connecting rod 130. When the user pedals the foot pedal 500, the weight training effect is better achieved.

[0050] In some embodiments of this application, the first sub-swing frame 310 includes a first swing frame section 311 and a second swing frame section 312, which are fixed as a single structure. The first swing frame section 311 has an elongated arc-shaped structure, and the second swing frame section 312 has a connecting plate structure.

[0051] One end (upper end) of the first section 311 of the swing frame is connected to the foot pedal 500, and the other opposite end (lower end) of the first section 311 of the swing frame is provided with the first hanging part 330. The second section 312 of the swing frame is connected to the first section 311 of the swing frame, and the first connecting rod 130 is rotatably connected to the second section 312 of the swing frame.

[0052] The first section 311 of the swing frame is used to set the first hanging part and the foot pedal 500, and the second section 312 of the swing frame is used to rotatably connect with the upright frame 120 and the connecting frame 600. The functions of the two are clearly defined.

[0053] In some embodiments of this application, a fourth connecting rod 150 is provided between the two first sub-swing frames 310, and the fourth connecting rod 150 is rotatably connected to the fixed frame 100. The fourth connecting rod 150 is obliquely positioned, with its lower end rotatably connected to the upright frame 120, and its upper end connected across the two first sub-swing frames 310 by a crossbar.

[0054] The reliability of the rotational connection between the first swing frame 300 and the upright frame 120 is further enhanced by the fourth connecting rod 150, thereby improving the reliability of the first swing frame 300 during the swinging process.

[0055] In some embodiments of this application, a second connecting rod 320 is provided between the two first sub-swing frames 310, and the two ends of the second connecting rod 320 are respectively rotatably connected to the connecting frame 600, and any one of the connecting frames 600 is rotatably connected to the second swing frame 400.

[0056] The second connecting rod 320 is designed to facilitate connection with the connecting frame 600 without interfering with the swinging motion of the first swing frame 300. The swinging motion of the first swing frame 300 is then transmitted to the second swing frame 400 through the connecting frame 600, thereby enabling the swinging motion of the second swing frame 400.

[0057] In some embodiments of this application, reference is made to Figure 3 The fixed frame 100 includes a third connecting rod 140, the two ends of which are rotatably connected to the second swing frame 400. The rotatable connection between the second swing frame 400 and the fixed frame 100 is achieved through the third connecting rod 140, and the rotatable connection position between the third connecting rod 140 and the second swing frame 400 is the fourth rotation position P4.

[0058] In some embodiments of this application, reference is made to Figure 1 and Figure 2 The fixed frame 100 is provided with a plurality of third hanging parts 160, which are configured to hang idle counterweight plates 700.
