Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 4 As shown, the utility model provides aerobics jumping training device, including a bottom plate 1, suction cups are fixedly connected to the bottom of the bottom plate 1 around the four sides, telescopic components 2 are fixedly connected to the top of the bottom plate 1 around the four sides, wherein the tops of two telescopic components 2 are hinged to the same top plate 3, the bottom plate 1 and the top plate 3 are each provided with a plurality of placement grooves 6 on one side close to each other, the outer side of the placement groove 6 is arc-shaped, springs 8 are placed inside the placement grooves 6 opened on the top of the bottom plate 1, and fixed components 7 are used to fix the springs 8, and the fixed components 7 are connected to the bottom plate 1, and the telescopic components 2 include a lower connecting seat 201 fixedly connected to the top of the bottom plate 1 around the four sides, and the lower connecting seat 201 is provided with a sliding groove 2 03, the sliding groove 203 is internally slidably connected with an upper connecting seat 202, and a sliding block is fixedly connected to the bottom of the upper connecting seat 202, and the shape of the sliding block is consistent with that of the sliding groove 203. The fixing assembly 7 includes a fixing seat 701 fixedly connected to the top of the bottom plate 1, and a plurality of stress holes are opened inside the fixing seat 701. The top end of the inner side of the fixing seat 701 is fixedly connected with a limiting sleeve 702, and the middle part of the inner side of the fixing seat 701 is fixedly connected with a reinforcement ring 703, and the other end of the reinforcement ring 703 is fixedly connected with the limiting sleeve 702. Both the reinforcement ring 703 and the limiting sleeve 702 are made of elastic metal, and the upper half of the limiting sleeve 702 is a shape in which the diameter gradually decreases downward, and the lower half is cylindrical.

[0026] The device is fixed to the ground by a suction cup, and then a person stands on the top of the top plate 3 for jumping training. When the person steps on the device, the top plate 3 presses the spring 8 and the upper connecting seat 202 downward, the spring 8 contracts and stores energy, and the upper connecting seat 202 slides inside the sliding groove 203 to limit the top plate 3 and prevent the top plate 3 from being misplaced. When the spring 8 is deformed, the spring 8 is clamped and limited by the lower half of the limiting sleeve 702, and the clamping force of the limiting sleeve 702 is increased by the reinforcement ring 703 to ensure the stability of the spring 8 during extension and contraction, prevent it from shaking left and right, and improve the stability of the device. Then the spring 8 rebounds, lifts up the top plate 3, gives the person an upward force, and assists in jumping training.

[0027] like Figures 1 to 4 As shown, the clamping assembly 4 is used to fix the top plate 3, and the clamping assembly 4 is connected to the telescopic assembly 2. There are four clamping assemblies 4, which are distributed in pairs at the top of the two telescopic assemblies 2 away from the top plate 3. The shape and position of the clamping assembly 4 correspond to the card slot 5 one by one. The clamping assembly 4 includes a clamping sleeve 401 fixedly connected to the top of the upper connecting seat 202. The clamping sleeve 401 is a hollow structure. Both sides of the clamping sleeve 401 are fixedly connected with spring pieces 402. The spring pieces 402 are elastic metal. The clamping sleeve 401 and the elastic An avoidance groove is provided on the contact surface of the sheet 402, and a protrusion 403 is fixedly connected to the other end of the spring sheet 402. Reinforcement grooves adapted to the protrusion 403 are provided on both sides of the slot 5. The positions of the placement grooves 6 on the inner sides of the bottom plate 1 and the top plate 3 correspond one to one.

The setting of the upper half of the diameter of the limiting sleeve 702 gradually reducing downward can expand the insertion range, facilitate the placement of the spring 8, and increase the accuracy during replacement. The design of the clamping assembly 4 allows the top plate 3 to be fixed or unlocked. When replacing, only the damaged spring 8 needs to be replaced, and there is no need to replace the entire row of springs 8, thereby saving cost and time and increasing the practicality of the device.

[0029] Principle and process of this utility model:

[0030] The device is fixed to the ground by a suction cup, and then a person stands on the top of the top plate 3 for jumping training. When the person steps on the device, the top plate 3 presses the spring 8 and the upper connecting seat 202 downward, the spring 8 contracts and stores energy, and the upper connecting seat 202 slides inside the sliding groove 203 to limit the top plate 3 to prevent the top plate 3 from being misplaced. When the spring 8 is deformed, the spring 8 is clamped and limited by the lower half of the limiting sleeve 702, and the clamping of the limiting sleeve 702 is increased by the reinforcing ring 703. The spring 8 rebounds and lifts the top plate 3, giving the personnel an upward force to assist in jumping training; when the spring 8 needs to be checked or replaced, the top plate 3 is rotated so that the reinforcement groove squeezes the protrusion 403 and pushes the spring piece 402 to deform inward to the avoidance groove until the protrusion 403 is separated from the reinforcement groove, so that the top plate 3 is unlocked, the top plate 3 is opened, and then the damaged spring 8 is checked, taken out and replaced, and then the new spring 8 is placed in the corresponding fixing seat 701, and then the top plate 3 is closed and locked.
