Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on the present application. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0021] like Figure 1-4 As shown, a jumping training high touch device includes a bracket 1, racks 2 are fixedly provided at positions near both sides of the bracket 1, gears 3 are meshed on the two racks 2, ratchet mechanisms are fixedly provided inside the two gears 3, the ratchet mechanisms include ratchet wheels 4, the outer wall of the ratchet wheels 4 is fixedly connected to the gear 3, a ratchet groove 5 is provided inside the ratchet wheels 4, a pawl plate 7 is provided inside the ratchet wheels 4, a pawl 6 is fixedly provided on the pawl plate 7, the pawl 6 is meshed with the ratchet groove 5, the pawl plate 7 drives the pawl 6 to rotate, thereby driving the ratchet wheels 4 and the gear 3 to rotate, and the gear 3 moves upward during the rotation.

[0022] The two ratchet mechanisms are fixedly connected by a rotating rod 8, and the two ends of the rotating rod 8 are respectively connected to the center points of the two pawl disks 7. An inclined touch plate 9 is fixedly arranged in the middle part of the rotating rod 8, and the touch plate 9 is inclined toward the side away from the bracket 1. A first spring 10 is fixedly arranged on the side of the touch plate 9 close to the bracket 1, and the other end of the first spring 10 extends toward the bracket 1. When performing jumping training, the trainee jumps upward and pushes the touch plate 9, and the touch plate 9 rotates around the axis of the rotating rod 8, and at the same time drives the rotating rod 8, the pawl disk 7 and the pawl 6 to rotate, and the pawl 6 drives the ratchet 4 and the gear 3 to rotate, which can drive the gear 3, the ratchet mechanism, the rotating rod 8 and the touch plate 9 to move upward. When the trainee lands on the ground, the first spring 10 will rebound, pushing the touch plate 9 back to its initial position, and driving the rotating rod 8, the ratchet plate 7 and the ratchet 6 to rotate. At this time, the gear 3 will not rotate with the ratchet plate 7. When the trainee jumps again, the touch plate 9 will be pushed again, which can drive the gear 3, the ratchet mechanism, the rotating rod 8 and the touch plate 9 to move upward a certain distance again. In this way, the height of the touch plate 9 from the ground can be automatically adjusted until the trainee can no longer push the touch plate 9. When the trainee can push the touch plate upward, it means that the trainee's jumping ability is improved, thereby achieving the purpose of jumping training and testing.

[0023] In this embodiment, a limiting device is also provided on the bracket 1. There are two groups of limiting devices. The two groups of limiting devices are respectively arranged on both sides of the touch plate 9 and close to the rack 2. The limiting device is used to limit the up and down position and the front and back position of the gear 3 and the touch plate 9.

[0024] The limiting device includes a fixing plate 11 fixed on the bracket 1, a first slider 12 is slidably provided on the fixing plate 11, a rotating rod 8 passes through the first slider 12 and is rotatably connected to the first slider 12, a plurality of first grooves 13 are evenly distributed on the front side of the fixing plate 11 from top to bottom, a second groove 15 is provided inside the first slider 12, a convex block 14 is slidably provided in the second groove 15, and the shape of the convex block 14 is the same as that of the first groove 13, a second spring 16 is fixedly provided on one side of the convex block 14 close to the second groove 15, and the other end of the second spring 16 is fixed on the second On the side wall of the groove 15, when the rotating rod 8 moves upward, the first slider 12 also moves upward with the rotating rod 8, the first slider 12 slides upward relative to the fixed plate 11, the protrusion 14 is pushed into the second groove 15, and the second spring 16 is compressed. When the first slider 12 and the protrusion 14 move to the position corresponding to the first groove 13, the second spring 16 rebounds and pushes the protrusion 14 into the first groove 13, limiting the position of the protrusion 14 and the first slider 12, and also limiting the rotating rod 8 and the gear 3 to prevent them from moving downward.

[0025] Preferably, the back side of the fixed plate 11 near the top and bottom ends is fixedly connected to the bracket 1 through fixed blocks respectively, and a second slide is provided on the front side of the bracket 1 at a position corresponding to the fixed plate 11, and the first slider 12 is slidably connected to the second slide, and the fixed plate 11 passes through the first slider 12 and is slidably connected to the first slider 12, thereby limiting the front and rear directions of the first slider 12, the rotating rod 8 and the gear 3.

[0026] In this embodiment, the first groove 13 includes a straight wall 17 and a curved wall 18. The straight wall 17 has a front side wall of the fixed plate 11 extending toward the inside of the fixed plate 11 and is perpendicular to the front and rear side walls of the fixed plate 11. One end of the straight wall 17 located inside the fixed plate 11 extends obliquely upward to form the curved wall 18. The end of the curved wall 18 away from the straight wall 17 is located on the front side wall of the fixed plate 11. Due to the provision of the curved wall 18, when the slider and the protrusion 14 move upward, the protrusion 14 is gradually pushed into the second groove 15. When the position of the protrusion 14 corresponds to the position of the first groove 13, the protrusion 14 is pushed into the first groove 13 under the action of the second spring 16. The straight wall 17 limits the first slider 12, the rotating rod 8 and the gear 3 up and down to prevent the gear 3 and the rotating rod 8 from falling.

[0027] Preferably, a first slideway is provided on both the top wall and the bottom wall of the second groove 15 , a second slider is slidably provided in the first slideway, and the second slider is fixedly connected to the protrusion 14 to realize the sliding of the protrusion 14 .

[0028] Preferably, the distance of the upward movement of the rotating rod 8 can be calculated according to the rotation angles of the touch plate 9 and the gear 3, and then the distance between the plurality of first grooves 13 on the fixing plate 11 can be set according to the distance.

[0029] When the present embodiment is in use, the trainee jumps upwards and pushes the touch plate 9, which rotates around the axis of the rotating rod 8, thereby driving the rotating rod 8, the ratchet plate 7 and the ratchet 6 to rotate. The rotation of the ratchet 6 drives the ratchet 4 and the gear 3 to rotate. When the gear 3 rotates, it drives the rotating rod 8, the ratchet 4 mechanism and the touch plate 9 to move upwards, and also drives the first slider 12 and the protrusion 14 to move upwards a certain distance. At this time, the first spring 10 is compressed. When the trainee falls, the first spring 10 pushes the touch plate 9 back to the initial direction, that is, drives the touch plate 9 to rotate around the rotating rod 8, thereby driving the rotating rod 8, the ratchet plate 7 and the ratchet 6 to rotate, so that the touch plate 9 can be returned to its original position. The trainee jumps up again and pushes the touch plate 9, and continues to drive the rotating rod 8 and the touch plate 9 to move upwards until the trainee cannot push the touch plate 9.

[0030] When the trainee performs jumping training, the touch plate automatically rises until the trainee cannot push the touch plate to rise. When the trainee has trained to a certain extent and can push the touch plate to rise, it indicates that the trainee's jumping ability has been improved, achieving the purpose of jumping training, and the trainee's jumping ability can be automatically tested.

[0031] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
