[0036] The leg placement assembly includes a support sleeve rod 5, a moving rod 6, a return spring 7, a support plate 8 and a soft pad 9. The support sleeve rod 5 is fixedly connected to both sides of the upper surface of the fixed platform 4. The moving rod 6 is slidably connected to the inner cavity of the support sleeve rod 5. The top of the moving rod 6 is fixedly connected to the support plate 8. The upper surface of the support plate 8 is fixedly connected to the soft pad 9. One end of the return spring 7 is fixedly connected to both sides of the upper surface of the fixed platform 4, and the other end of the return spring 7 is fixedly connected to the bottom surface of the support plate 8;

[0037] The support assembly 2 includes a rectangular moving rod 201, a rectangular fixed rod 202, a fixed block 203, a threaded rod 204 and a bevel gear A205. The rectangular moving rod 201 is fixedly arranged on the bottom surface of the fixed plate 4. The interior of the rectangular moving rod 201 and the interior of the rectangular fixed rod 202 are both provided with an inner cavity. The rectangular fixed rod 202 is slidably connected to the inner cavity of the rectangular moving rod 201. The bottom end of the rectangular fixed rod 202 is fixedly connected to the fixed base plate 1.

[0038] A fixed block 203 is fixedly provided in the inner cavity of the rectangular fixed rod 202, and a threaded rod 204 is rotatably connected to the upper wall of the inner cavity of the rectangular movable rod 201. The threaded rod 204 extends into the inner cavity of the rectangular fixed rod 202, and the threaded rod 204 passes through the fixed block 203 and is threadedly engaged with the fixed block 203. A bevel gear A205 is fixedly provided at the top of the threaded rod 204. According to the present technical solution, the rotation of the bevel gear A205 can drive the threaded rod 204 to rotate, and then the rotation of the threaded rod 204 can drive the rectangular movable rod 201 to move;

[0039] The downward pressure adjustment assembly 3 includes a rotating rod 301, a bevel gear B302, a rotating disk 303, a ratchet 304, a gear 305, a pawl 306, a tooth plate 307, a limit spring 308, a sleeve 309 and a locking bolt 310. The rotating rod 301 is arranged on the side wall of the rectangular moving rod 201 and is rotatably connected to the rectangular moving rod 201. One end of the rotating rod 301 extends into the inner cavity of the rectangular moving rod 201. The bevel gear B302 is fixedly connected to one end of the rotating rod 301. The bevel gear B302 is meshed with the bevel gear A205.

[0040] The rotating disk 303 is fixedly connected to the arc-shaped wall of the rotating rod 301, and the sleeve 309 is rotatably connected to the arc-shaped wall of the rotating rod 301. The locking bolt 310 is threadedly connected to the sleeve 309. The ratchet 304 is fixedly provided on the arc-shaped wall of the sleeve 309. The gear 305 is rotatably connected to the ratchet 304. A pawl 306 is provided on the arc-shaped inner wall of the gear 305. The tooth plate 307 is meshed with the gear 305. The top of the tooth plate 307 is engaged with the gear 305. The end is fixedly connected to the bottom surface of the support plate 8. Through the technical solution, the locking bolt 310 is in a locked state before use, so that the sleeve 309 and the rotating rod 301 are fixed. When the user performs leg press training, the leg is placed on the upper surface of the soft pad 9 to perform downward pressure training. When the leg is pressed down, the support plate 8 is also pressed to move downward. Leg press training is usually performed by pressing the upper body on the leg for a period of time, and then the upper body is straightened to relax the leg. The gear 305 is driven by the toothed plate 307 and the gear 305 is driven to rotate, which makes the gear 305 shown in the fixed plate 4 rotate clockwise, thereby driving the ratchet 304 to rotate through the pawl 306, and then driving the sleeve 309 to rotate. Since the sleeve 309 is locked and fixed with the rotating rod 301 at this time, the rotating rod 301 can be driven to rotate, thereby making the support assembly 2 extend, so that the device as a whole is lifted up a certain distance, so that the user can gradually lift the device when performing reciprocating leg press training, so that the training intensity can be gradually increased, thereby effectively avoiding the problem of injury caused by using a high training height at one time. The use of this device can make the training intensity gradually increase during the training process, and achieve a better training effect.

[0041] When the training is finished and the device needs to be reset, the locking bolt 310 can be loosened to unlock the locking bolt 310, so that the rotating disk 303 can be manually rotated to drive the rotating rod 301 to rotate freely, and the support assembly 2 can be adjusted back to the appropriate height, and then the locking bolt 310 can be locked again.

[0042] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
