[0018] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present disclosure or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without inventive effort are within the scope of protection of this disclosure.

[0019] Please see Figure 1 As shown, this embodiment is a safety training device for children's jumping ability. The main components include: a mounting platform 11, a spring plate 32 mounted on the mounting platform 11, auxiliary ramps 31 symmetrically mounted on the front and rear sides of the spring plate 32, and fixed frames 12 mounted on the four corners of the mounting platform 11. Each fixed frame 12 is fixedly mounted with a fixed cylinder 13 and a stud 14 slidably connected to the fixed cylinder 13. The fixed cylinder 13 and the stud 14 form a support column. The height of the fixed cylinder is generally no greater than the minimum height of the safety bar required by the child being trained, making it convenient for children to use. A gap is left between the fixed cylinder and the stud to avoid affecting the up-and-down movement of the stud 14 within the fixed cylinder. Two height-adjustable safety bars 15 are symmetrically mounted on the upper ends of the two support columns for the trainee to grab onto for easy jumping and to ensure safety during training. A mounting assembly is provided below the spring plate 32, through which the spring plate 32 is mounted on the mounting platform 11. The spring board 32 is for trainees to step on and bounce; the auxiliary ramps 31 on both sides make it easy for children to safely walk or jump onto the spring board 32.

[0020] like Figure 2 and Figure 4 As shown, the adjustment assembly is mainly used to adjust the height of the safety bar 15, including: a handle 21 and an adjustment rod 23. The handle 21 is fixedly installed on the outside of the fixed frame 12 and connected to one end of the adjustment rod 23. The other end of the adjustment rod 23 is rotatably installed in the symmetrical fixed frame 12. A first bevel gear 25 is installed at each end near the two ends of the adjustment rod 23. The adjustment assembly also includes a threaded rod 26 perpendicular to the adjustment rod 23. A second bevel gear 24 that meshes with the first bevel gear 25 is installed at the lower end of the threaded rod 26. The threaded rod 26 and the stud 14 are connected by threads through the meshing first bevel gear 25 and second bevel gear 24. The stud 14 is an internally threaded stud, which mates with the thread of the threaded rod 26. The threaded rod 26 and the stud 14 are connected by internal threads. For safety, a connecting sleeve 22 is installed on the outer periphery of the adjustment rod 23. A gap is left between the adjustment rod 23 and the connecting sleeve 22. The size of the gap should be such that it does not affect the rotation of the adjustment rod 23.

[0021] like Figure 3As shown, a mounting assembly is provided below the spring plate 32, and the spring plate 32 is mounted on the mounting platform 11 through the mounting assembly below it. The mounting assembly includes: a frame 34 for mounting the spring provided below the spring plate 32, a spring sleeve post 35 located at the center of the frame 34, and a spring fixing block 36 coaxial with the spring sleeve post 35, and a compression spring 37 sleeved on the spring sleeve post 35.

[0022] The working principle and usage method are as follows: When children are doing jumping training, firstly, by rotating the handle 21 clockwise, the mounting rod 23, which is fixedly connected to one end of the handle 21, rotates inside the connecting cylinder 22. Through the meshing of two sets of gears and the threaded rod 26, the height of the safety bar 15 is adjusted to the height required by the trainee. Then, the child steps on the top of the spring plate 32 through the auxiliary ramp 31. The downward pressure generated by jumping while holding the safety bar compresses the spring plate 32, causing the sleeve 35, which is fixedly connected to the bottom of the spring plate 32, to slide inside the auxiliary frame 34. The spring fixing block 36 on the sleeve 35 compresses the compression spring 37, causing the spring plate 32 to rebound under the action of elasticity, thereby realizing the child's jumping training and providing muscle training for the ankle, calf, and thigh.

[0023] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model.
