[0022] See also Figure 1-4 The utility model provides a technical solution for a leg training device built in a square:

[0023] A leg training device for use in a square comprises a bracket 1, wherein two spaced-apart side panels 2 are fixedly mounted on the upper end of the bracket 1, a connecting seat 3 is rotatably mounted between the two side panels 2, an extension rod 4 is fixedly mounted on the connecting seat 3, one end of the extension rod 4 extending downward to a point, and a plurality of equally spaced limiting holes 5 are formed at the lower end of the extension rod 4. A sliding seat 6 is sleeved on the extension rod 4 and can slide along the extension rod 4. Limiting mechanisms are provided on both sides of the sliding seat 6 to secure the sliding seat 6 to the extension rod 4. A plate 7 is fixedly mounted on the bracket 1, a push rod 8 being provided on one side of the plate 7, one end of the push rod 8 being fixedly connected to the sliding seat 6, a support rod 11 being fixedly mounted on the other side of the sliding seat 6, a seat cushion 12 being fixedly mounted on the support rod 11, and a reclining board 13 being fixedly mounted on the upper end of the support rod 11. A user sits on the seat cushion 12 and lies on the reclining board 13, and by pushing against the plate 7, the user moves the body to one side, thereby exercising the legs.

[0024] Among them, a rubber pad 9 is fixedly installed on the end of the top rod 8 facing the plate 7, and a buffer layer 10 is fixedly connected to the side of the plate 7 facing the top rod 8. The surfaces of the seat cushion 12 and the lying plate 13 are provided with anti-slip grooves. The limiting mechanism includes a limiting rod 14, which passes through the sliding seat 6. One end of the limiting rod 14 can be inserted into the limiting hole 5. A disc 15 is fixedly installed on one end of the limiting rod 14. An elastic member 16 is sleeved on the limiting rod 14, and the two ends of the elastic member 16 are respectively fixedly connected to the sliding seat 6 and the disc 15. A plurality of embedded rods 17 distributed in a circular array are fixedly installed at the bottom of the bracket 1. The embedded rods 17 are configured as barbed hooks. By moving the sliding seat 6 along the extension rod 4, the height of the sliding seat 6, the support rod 11 and the seat cushion 12 can be adjusted, thereby adjusting the height of the seat cushion 12. Then, by inserting one end of the limiting rod 14 into the limiting hole 5, the position of the sliding seat 6 and the seat cushion 12 is fixed.

[0025] The bottom end of the seat plate 12 is fixedly mounted with a support plate 18, which is L-shaped. Two vertical rods 19 are fixedly mounted on the support plate 18, spaced apart. Weights 20 are placed on the support plate 18, and the vertical rods 19 are inserted into the weights 20. The lower end of the bracket 1 is buried underground, and the buried rods 17 are also buried underground. The buried rods 17 are designed in a barbed shape to prevent the bracket 1 from being dislodged from the ground, thus improving the secure installation of the bracket 1. By placing weights 20 on the support plate 18, the weight of the seat plate 12 can be increased, thereby adjusting the weight of the leg kick according to the desired exercise.

[0026] The working principle of the present invention is as follows: the user sits on the seat plate 12 and lies on the reclining plate 13, and uses the footrest plate 7 to move the body to one side, thereby exercising the legs. By moving the sliding seat 6 along the extension rod 4, the height of the sliding seat 6, the support rod 11 and the seat plate 12 can be adjusted, thereby adjusting the height of the seat plate 12. Then, by inserting one end of the limiting rod 14 into the limiting hole 5, the position of the sliding seat 6 and the seat plate 12 is fixed.

[0027] The lower end of bracket 1 is buried underground, along with embedded rod 17. Embedded rod 17 is designed in a barbed shape to prevent bracket 1 from being dislodged from the ground, enhancing the secure installation of bracket 1. By placing weights 20 on support plate 18, the weight of seat plate 12 can be increased, allowing the weight of the leg kick to be adjusted according to the desired exercise. The body is moved sideways by using footrest plate 7, which synchronizes the movement of seat plate 12. When seat plate 12 returns to its original position, one end of push rod 8 strikes plate 7. The impact between push rod 8 and plate 7 is cushioned by rubber pad 9 and buffer layer 10.

[0028] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
