[0024] like Figure 1As shown, the movable surface 13 is positioned higher than the surface of the base plate 1 and is inclined downwards towards the base plate 1, i.e., the movable surface 13 is inclined downwards from right to left. Specifically, the movable surface 13 includes two guide surfaces 131 inclined downwards along its middle section. The two guide surfaces 131 form a V-shaped structure and are connected by an arc surface 132. By setting the inclined movable surface 13, guide surfaces 131, arc surface 132, and two connecting ropes 61, the elastic ball 6 can be quickly reset and the reset accuracy of the elastic ball 6 can be greatly improved, which is beneficial for children's lower limb training.

[0025] A baffle 14 is provided at the connection between the activity area 11 and the base plate 1. The upper part of the baffle 14 is higher than the position of the movable surface 13 at the connection between the activity area 11 and the base plate 1. The side of the baffle 14 facing the base plate 1 is inclined, and foam can be placed on the inclined surface to prevent children from accidentally kicking the baffle 14 and injuring their feet. The height of the baffle 14 is smaller than the diameter of the bouncy ball 6 to avoid excessive obstruction of the bouncy ball 6. By setting the baffle 14, the bouncy ball 6 can be blocked, which is conducive to the return of the bouncy ball 6 to its original position.

[0026] An adjustment frame 2 is provided above the base plate 1. A handrail 4 is provided on the side of the adjustment frame 2 away from the activity area 11. Specifically, the adjustment frame 2 includes a C-shaped bracket 21 fixed to the base plate 1. An adjustment column 22 is connected to the upper part of the C-shaped bracket 21. A crossbar 3 is connected to the side of the adjustment column 22. The handrail 4 is connected to both ends of the crossbar 3. By fixing the handrail 4 to both ends of the crossbar 3, children can hold the handrail 4 with both hands when training, thereby preventing children from falling when kicking the ball and improving safety.

[0027] Specifically, the crossbar 3 can be adjusted up and down in height. There are at least two adjusting posts 22. On the side of the adjusting post 22 away from the handrail 4, there are multiple studs 23 arranged along its height direction. The crossbar 3 is horizontally sleeved on the outside of the corresponding stud 23 and fixedly connected to the stud 23 by a nut. The two handrails 4 can move closer or further apart. One end of the handrail 4 is fixed with a sliding sleeve 41. The sliding sleeve 41 is sleeved on the outside of the crossbar 3. The sliding sleeve 41 is fixed to the crossbar 3 by a handle bolt 5. The crossbar 3 includes multiple through holes 31 arranged along its length direction. The handle bolt 5 is threadedly connected to the sliding sleeve 41 and its end can be inserted into the corresponding through hole 31. Through the above design, the position adjustment between the two handrails 4 and the height adjustment of the handrails 4 can be realized to meet the training needs of different children.

[0028] Adjustable seats 15 are fixed on both sides of the base plate 1. The upper part of the adjustable seat 15 is provided with a plurality of limiting holes 16 arranged along its length. The two ends of the C-shaped bracket 21 can be inserted into the limiting holes 16 for limiting. Specifically, the lower end of the C-shaped bracket 21 is provided with a support plate 24. The lower part of the support plate 24 is provided with two protrusions 25. The lower part of the support plate 24 abuts against the upper part of the adjustable seat 15. The two protrusions 25 can be inserted into two adjacent limiting holes 16. The C-shaped bracket 21 and the adjustable seat 15 are designed to be plugged in, that is, the C-shaped bracket 21 can be pulled out directly upwards and its position adjusted. It is easy to operate and can meet the usage needs of different children. Furthermore, by setting two protrusions 25 and a support plate 24, the contact area between the lower end of the C-shaped bracket 21 and the adjustable seat 15 can be increased, thereby greatly improving the stability of the C-shaped bracket 21.

[0029] The protrusion 25 has a protruding post 26 at its lower part. A rubber sleeve 7 is fixedly connected to the outside of the protruding post 26. The side wall of the rubber sleeve 7 is elastically interference-fitted with the inner wall of the limiting hole 16. A triangular plate 27 is fixedly connected to the side of the C-shaped bracket 21. The lower part of the triangular plate 27 is fixedly connected to the upper part of the support plate 24. By setting the protruding post 26, the insertion depth of the C-shaped bracket 21 can be increased. Furthermore, through the cooperation between the rubber sleeve 7 and the limiting hole 16, the adjusting frame 2 requires a certain amount of force from an adult to pull it upward and separate it from the adjusting seat 15. This ensures both the stable support of the C-shaped bracket 21 and the detachable adjustment of the adjusting frame 2.

[0030] This embodiment also includes a seat plate 8. Both the seat plate 8 and the base plate 1 are mounted on the side wall of the wall 9. The seat plate 8 is located above the base plate 1.

The other end of the pull rope 82 is fixedly connected to the wall 9, and the position of the connection end to the wall 9 is higher than the position of the bushings 81. A first magnet 83 is provided on the side of the seat plate 8 facing the wall 9. A second magnet 83 is provided on the surface of the wall 9. Two magnets 91 are used. The seat plate 8 can abut against the wall 9 so that the first magnet 83 and the second magnet 91 can be attracted together. When the seat plate 8 is not in use, the seat plate 8 rotates along the hinge point with the bushing 81 so that the side of the seat plate 8 abuts against the side of the wall 9. The attraction of the first magnet 83 and the second magnet 91 can prevent the seat plate 8 from falling and opening. When the child needs to rest, the seat plate 8 can be opened by simply bending it downwards. The child can sit on the seat plate 8 to rest. The seat plate 8 is held in place by the pull rope 82 to prevent it from falling.
