Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of leg bounce, especially relates to a leg bounce training device. BACKGROUND

[0002] Leg bounce training is to increase the bounce ability of legs through training mode, specifically, leg bounce training is to realize the training of leg muscles, and the bounce ability of legs is increased after the training of leg muscles, and the trained personnel can not only bounce higher, but also bounce farther.

[0003] The current leg bounce training mode is a bounce and jump mode, which can improve the bounce ability of legs and realize the strengthening training of leg muscles. However, the training mode has obvious disadvantages, that is, the bounce and jump mode consumes too much physical strength of the trained personnel in the training process, and the trained personnel cannot continue the training due to too strong fatigue after a period of training. Specifically, the bounce and jump mode training requires the force of legs and the force of all limbs of the body, and the rebound force of the ground on the feet is very large when bouncing on the ground, so the feet of the trained personnel are sore and the physical strength is consumed too much after a period of training.

[0004] Therefore, the current training mode does not train the legs independently, so that the training effect is not obvious. Specifically, the existing training equipment, such as weight lifting, arm pulling and jump, cannot independently strengthen the training of legs.

[0005] Therefore, if the independent strengthening training of legs cannot be carried out in the training process, the bounce ability of legs cannot be improved in a short time, and the training efficiency is too low due to the non-targeted training, and the trained personnel is easily injured in the training process, such as the feet being sprained in the bounce and jump training.

[0042] Example 1

[0043] like Figures 1-6 As shown, a leg jumping training device includes a training frame 1, on which a leg jumping training mechanism 2 is mounted and connected.

[0044] Specifically, the leg jumping training mechanism 2 includes jumping structures spaced apart on both the left and right sides, enabling independent and targeted training of the trainee's legs.

[0045] Specifically, the bouncing structure comprises two spring telescopic members which are integrally connected and inclined at an angle of 30 degrees. Specifically, the spring telescopic member comprises a spring sleeve 23 (a plurality of through hole structures are formed on the spring sleeve 23). Meanwhile, a piston seat 243 is slidably connected in the spring sleeve 23, the spring 242 is fixedly connected on the piston seat 243, and the spring 242 is fixedly connected at the bottom of the spring sleeve 23; the push rods 24 are fixedly connected on the piston seat 243, and the push rods 24 are fixedly connected between them and have an angle of 30 degrees. Meanwhile, the connecting rods 241 are fixedly connected between the top portions of the push rods 24, and the connecting rods 241 are installed with the foot pedal 21 through the hinge structure, specifically at the bottom center position of the foot pedal 21.

[0046] Specifically, the hinge structure 2411 comprises a hinge fixed seat fixedly connected on the foot pedal 21, and a hinge ball is hingedly connected in the hinge fixed seat, which is the same as the existing spherical hinge structure.

[0047] Meanwhile, the top of the foot pedal 21 is provided with a sunken groove, and a plurality of straps 211 are fixedly connected on the side walls on both sides of the foot pedal 21. During the training process, the operator stands on the sunken groove with both feet and is fixedly bound through the straps 211. In order to facilitate the binding, the Velcro is installed on the strap 211 according to the existing mode.

[0048] Subsequently, during the training process, the operator forces the foot pedal 21 downward, and under the drive of the foot pedal 21, the push rod 24 drives the piston seat 243 to repeatedly press the spring 242, and after the operator's feet are lifted, the spring 242 is reset.

[0049] During the repeated treading process, the operator needs to overcome the elastic resistance of the four springs 242, so the leg muscles, especially the thigh muscles, need to be exerted to force the foot pedal 21 downward. Through this, the leg is independently and concentratedly trained. This training method not only can completely apply the physical strength to the leg training, but also greatly increases the training effect.

[0050] Meanwhile, the rotating arms 25 are fixedly connected between the bottoms of the spring telescopic members, the rotating shafts 26 are fixedly connected between the rotating arms 25, and the shaft cylinder supports are rotationally connected to the rotating shafts 26.

[0051] Specifically, the spring sleeve 23 is fixedly connected with the swing arms 231 at the bottom, and the swing arms 231 are fastened on the rotating arms 25 through the screw rods.

[0052] Meanwhile, the shaft support includes a roller section 27 (with a shaft cavity inside the roller section 27, and a bearing installed inside the shaft cavity in the conventional manner, and a rotating shaft 26 rotatably connected to the bearing), and the rotating shaft 26 is rotatably connected to the roller section 27. At the same time, several support sections 28 are fixedly connected to the bottom of the roller section 27, and the support sections 28 are installed on the training support 1.

[0053] During operation, the above structure allows for the coordination of leg swing training with the leg compression spring 242 training. Specifically, when swinging backward, the leg pushes backward along with the foot pedal 21. Because the foot pedal 21 is hinged, its posture is easily synchronized with the foot posture during the push. Subsequently, the rotating arm 25 rotates, and the rotating shaft 26 rotates.

[0054] At this time, the operator can also perform training by forcefully pressing the foot pedal 21 and squeezing the spring 242. This method allows for different ways of exerting force during leg training, thereby improving the training effect.

[0055] Example 2

[0056] like Figures 1-6 As shown, in this embodiment, based on the structure of Embodiment 1, a U-shaped support arm 11 is fixedly connected to the training bracket 1; a pair of lifting hand rings 12 are fixedly connected to the bottom of the support arm 11. During training, the trainee's torso is supported by the lifting hand rings 12 with slight force to maintain body balance, and if the body loses balance, the balance can be corrected by pulling the lifting hand rings 12.

[0057] Example 3

[0058] like Figures 1-6 As shown, in this embodiment, based on the structure of embodiment 2, the two ends of the rotating shaft 26 are respectively threaded with friction-increasing structures 3 that abut against the side wall of the shaft support. Through the friction-increasing structures 3, the rotational resistance of the foot pedal 21 is increased. By using the friction-increasing structures 3, the operator can drive the foot pedal 21 to move in a swinging manner, thereby increasing the swing resistance and exercising the muscles of the calf. Specifically, the swing resistance is large, requiring the calf muscles to exert force.

[0059] Specifically, the friction-increasing structure 3 includes an adjusting disc 31 threadedly connected to the rotating shaft 26. The adjusting disc 31 is integrally formed with a threaded cylinder 32. The threaded cylinder 32 has an internal thread structure and a corresponding thread structure on the rotating shaft 26. The threaded cylinder 32 of a certain length has a larger thread depth and higher stability.

[0060] At the same time, the adjusting disc 31 is fixedly connected with a plurality of rubber material friction tabs 33 abutting against the side wall of the shaft cylinder support. Rotating the adjusting disc 31 to the friction tabs 33 abutting against the side wall of the roller portion 27 realizes the rotating process of the rotating shaft 26 carrying the adjusting disc 31 to rotate, the friction tabs 33 rubbing against the side wall of the roller portion 27, and the resistance of the rotating shaft 26 rotating is increased, so the trainer needs to turn over the calf part with more strength, and the calf part is exercised in this way.

[0061] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by the skilled in the art within the essential scope of the present application should also be within the protection scope of the present application.
