[0030] Working principle and technical effect of the present invention: When exercising the leg muscles by running, the digital display control panel 9 controls the start of the second motor 607, and the second motor 607 drives the active roller 606 to rotate. The second meshing teeth 611 on the active roller 606 mesh with the first meshing teeth 602 on the inner side of the running track 601, driving the running track 601 to operate, and the first steering roller 603 and the second steering roller 604 can realize a U-shaped involvement of the running track 601, so that the active roller 606 and the second motor 607 can be located on the upper side of the inner part of the training box 1 to avoid being directly immersed in water during water exercise, thereby protecting the second motor 607 from water contact. When the user runs on the running track 601, adding water to the training chamber can provide additional resistance, thereby providing a mode of leg muscle exercise in water, thereby performing efficient muscle training while protecting the joints. The resistance of water is 800 of that of air. When exercising in water, the muscles need to overcome greater resistance to complete the movement, which makes the muscles more fully stimulated during exercise and can effectively enhance muscle strength and endurance. The water baffle 609 prevents water from splashing onto the active roller 606, and the cleaning brush 108 on the cover 101 cleans the surface of the running track 601.

[0031] When performing leg flexion and extension training, the user sits on the seat structure 8 and holds the handle 103 with both hands. The electric telescopic rod 402 is activated through the digital display control panel 9, and the electric telescopic rod 402 drives the weight block 404 to move on the guide rod 403 to adjust the weight of the leg weight rod assembly 7. The rotating disk 2 is rotated, and the rotating rod 701 drives the leg pressing rod 702 to rotate, and the user performs leg pressing training.

[0032] During training, if an accident occurs, that is, the legs become weak and suddenly fall, in order to prevent the leg pressure bar 702 from causing pressure injuries to the legs, the torque sensor 306 monitors the tension of the suspension rope 308 and feeds back the data to the digital display control panel 9. After the torque sensor 306 monitors the tension of the suspension rope 308 to reach a certain value, the digital display control panel 9 controls the first motor 303 to start, and the first motor 303 drives the rope reel 305 to rotate, and pulls the turntable 2 through the suspension rope 308 to prevent the leg pressure bar 702 from falling suddenly.

[0033] Turn on the digital display control panel 9, start the water pump 501, and draw out the water at the bottom of the training chamber through the third water pipe 504. After being filtered by the filter box 503, it is sent back to the upper side of the training chamber through the first water pipe 502 to achieve water circulation filtration. The first water pipe 502 and the fourth water pipe 505 can also be connected through the electromagnetic three-way valve 506 to discharge the water in the training box 1.

[0034] When in use, the seat plate 802 is rotated around the inner wall of the training box 1 through the hinge seat 801, so that the block 804 is inserted into the slot 803 on the seat plate 802, and the seat plate 802 is in a horizontal state, and the user can sit on the cushion 805 for training. When not in use, the seat plate 802 can be folded up to a vertical state to save space. Specifically, the handle 103 is first slid upward, that is, the slider 104 slides upward in the lifting slot 105, and then after the seat plate 802 is vertically folded, the handle 103 is dropped down, and the position of the seat plate 802 is fixed by the handle 103.

[0035] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
