Description

Technical Field

[0001] The present invention belongs to the technical field of bounce training, and particularly relates to a bounce training device and a training method capable of adjusting training postures. Background Art

[0002] Bouncing is a comprehensive manifestation of whole-body strength, running speed, reaction speed, body coordination, flexibility, and agility. Improving bouncing does not simply mean jumping all day long. One must persist in stretching the tendons, ligaments, and muscles of all parts of the body every day to expand the range of joint movement. At the same time, perform various complex gymnastics that are beneficial to improving body coordination, with accurate, graceful, powerful, and relaxed movements. Therefore, bounce training equipment is needed.

[0003] After retrieval, the publication number CN114100055A discloses a bounce training device for track and field sports with a protective structure in the field of bounce training, including a bottom plate. A sliding chamber is installed on the upper left side of the bottom plate, and a sliding column is installed on the upper end of the sliding chamber. When the above device is in use, although it can play a role in protecting the human body, the training posture cannot be adjusted. Prolonged training with incorrect postures of the training personnel is also likely to cause harm to the personnel. For this reason, a bounce training device and a training method capable of adjusting training postures are proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a bounce training device and a training method capable of adjusting training postures, which can use a waist belt to keep the human waist in a vertical state, adjust the bouncing posture of the human body, prevent the situation of body injury caused by the long-term deviation of the waist to one side during bouncing, and at the same time, the training personnel can observe their own postures through a display, which is convenient for self-checking and adjustment. The display can also automatically change the angle following the up and down movement of the human body, facilitating people's observation, and solving the existing technical problems.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] A bounce training device capable of adjusting training postures includes:

[0007] A base, on the upper surface of which two support frames are fixedly connected. A through sliding rod is slidably connected to the top of each of the two support frames. A fixed sleeve is fixedly connected to the bottom of each sliding rod. Plug rods are inserted into the opposite sides of the two fixed sleeves. A waist belt for keeping the waist vertical is rotatably connected to one side of each of the two plug rods. The two waist belts are used in cooperation and are both fixedly connected with magic tapes for bonding and fixing the two waist belts. The waist belt can keep the human waist in a vertical state, adjust the bouncing posture of the human body, and prevent the situation of body injury caused by the long-term deviation of the waist to one side during bouncing;

[0008] The surface of the base is provided with two safety areas for placing feet, which facilitate people to observe the landing positions.

[0009] An alarm mechanism is arranged at the bottom of the base to remind the training personnel.

[0010] Furthermore, one side of the other end of each of the two support frames is rotatably connected with a penetrating rotating shaft. A display is fixedly connected between the two rotating shafts. A mounting seat is fixedly connected to the top of the display. A camera electrically connected to the display is installed in the mounting seat through a damping shaft. After the camera and the display are started, the training personnel can observe their own postures through the display, which is convenient for self-check and adjustment. Driving components for controlling the angle of the display are arranged on both sides of the display.

[0011] Furthermore, the driving component includes a first wire reel, a first torsion spring, a first guide wheel and a connecting column. The connecting column is fixedly connected to one side of the sliding rod. The first guide wheel is rotatably connected to one side of the support frame. The first wire reel is fixedly connected to one end of the rotating shaft. The first torsion spring is sleeved on the circumference of the rotating shaft, and both ends of the first torsion spring are fixed to the support frame and the first wire reel respectively. A pull rope is fixedly wound around the circumference of the first wire reel. The other end of the pull rope bypasses the first guide wheel and is fixed to the connecting column. The setting that the display can rotate enables the display to automatically change the angle following the up and down movement of the human body during use, which is convenient for people to observe.

[0012] Furthermore, the alarm mechanism includes a support seat which is fixedly connected to the bottom surface of the base. Two installation grooves are opened at the top of the support seat. Sleeves are fixedly connected to the bottoms of the installation grooves. A penetrating piston rod is inserted into the top of each sleeve. Springs are fixedly connected between the bottom of the piston rod and the inner bottom wall of the sleeve. The tops of the multiple sleeves are fixedly communicated with the same air pipe. The air outlet end of the air pipe is fixedly connected to a whistle pipe. A pressing plate is fixedly connected between the tops of the multiple pressing plates, and the pressing plate is not in contact with the support seat. A rubber pad is fixedly connected to the top of the pressing plate, and the rubber pad is higher than the top of the base. The setting of the alarm mechanism enables a sound to be emitted through the whistle pipe when the landing position of the feet is incorrect during training, thereby reminding people.

[0013] Further, a fixing block is fixedly connected to the bottom surface of the base. One side of the fixing block is rotatably connected with a penetrating mounting shaft. Two symmetrically arranged second wire reels are fixedly connected to the circumference of the mounting shaft. Elastic ropes are fixedly wound around the circumferences of the second wire reels. The other ends of the elastic ropes are fixedly connected with hooks. Card seats for cooperating with the hooks are fixedly connected to the circumferences of the fixing sleeves. Second torsion springs are fixedly connected to one ends of the second wire reels. An adjusting component for adjusting the torque of the second torsion spring is arranged on one side of each second torsion spring. Two second guide wheels are fixedly connected to the bottom surface of the base. The two elastic ropes respectively bypass the two second guide wheels. The hooks are buckled on the card seats. When bouncing, the elastic ropes and the second torsion springs are used to pull the human body, increasing the training difficulty.

[0014] Further, the adjusting component includes a turntable and a setscrew. The turntable is rotatably connected to one side of the base. The other end of the second torsion spring is fixed to the turntable. A plurality of jacks are formed in the circumference of the turntable. The setscrew is threadedly connected to one side of the base and is used in cooperation with the jacks. By rotating the turntable, the torque of the second torsion spring can be changed, and the setscrew can be locked after adjustment.

[0015] Further, L-shaped handles are fixedly connected to the inner walls of the tops of the support frames. Anti-slip sleeves are fixedly connected to the circumferences of the handles. The handles are convenient for placing clothes.

[0016] Further, a limiting frame for limiting the angle of the display is fixedly connected between the support frames.

[0017] The present invention also proposes a training method for a bouncing training device with adjustable training postures, including the following steps:

[0018] S1. Enter above the base from the side far away from the display. Then wrap the two girdles around the waist from both sides and tighten the girdles through the magic tape. Step on the two safety areas with both feet, keep the leg postures, and then start training. When training, bounce upward. The girdle drives the sliding rod to move upward. The girdle and the sliding rod are used to keep the waist in a vertical state, fixing the bouncing posture and avoiding the phenomenon that the uneven force on the legs is caused by the side waist.

[0019] S2. When training, start the display and the camera. The camera takes pictures of the human body and then plays them on the display for the training people to view. The training personnel observe their own postures through the display.

[0020] S3. When the sliding rod moves upward, one end of the pull rope is driven to move through the connecting column. The other end of the pull rope drives the first wire reel to rotate. The first wire reel drives the display to rotate through the rotating shaft, and then the angle is adjusted according to the movement of the human body, facilitating people's observation.

[0021] S4. When landing after a bounce, when the foot steps on the rubber pad, the rubber pad drives the pressing plate to move downward. The pressing plate drives multiple piston rods to move within the sleeves, thereby quickly discharging the air inside the sleeves. Then, the gas is discharged through the air pipe and the whistle pipe, and a sound is emitted through the whistle pipe to remind people of incorrect landing positions.

[0022] S5. When carrying a load, hook the hook on the card seat, and use the elastic cord and the second torsion spring to pull the human body during the bounce to increase the training difficulty. When it is necessary to adjust the load, turn the setscrew so that the setscrew disengages from the jack, and then turn the turntable, thereby changing the torsion of the second torsion spring. After adjustment, lock the setscrew.

[0023] The embodiments of the present invention have the following beneficial effects:

[0024] In the present invention, through the arrangement of installing a vertically movable waist belt on the surface of the base, the waist belt can be used to keep the human waist in a vertical state, adjust the bouncing posture of the human body, and prevent the situation of body injury caused by the long-term deviation of the waist to one side during bouncing.

[0025] In the present invention, through the coordinated use of the camera and the display, when people use it, after starting the camera and the display, the training personnel can observe their own postures through the display, which is convenient for self-check and adjustment.

[0026] In the present invention, through the arrangement that the display can be rotated, when people use it, the display can follow the up and down movement of the human body and automatically change the angle, which is convenient for people to observe.

[0027] In the present invention, through the arrangement of the alarm mechanism, when people are training and the landing position of the foot is incorrect, a sound is emitted through the whistle pipe to remind people.

[0028] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

The training personnel observe their own postures through the display (11). S3. When the sliding rod (3) moves upward, one end of the pull rope (18) is driven to move through the connecting column (16). The other end of the pull rope (18) drives the first wire reel (14) to rotate. The first wire reel (14) drives the display (11) to rotate through the rotating shaft (10), so as to adjust the angle according to the movement of the human body and facilitate people to observe. S4. When landing after a bounce, when the foot steps on the rubber pad (37), the rubber pad (37) drives the pressure plate (36) to move downward. The pressure plate (36) drives a plurality of piston rods (34) to move within the sleeve (33), thereby quickly discharging the air within the sleeve (33). Then the gas is discharged through the trachea (38) and the whistle tube (39), and a sound is emitted through the whistle tube (39) to remind people of the wrong landing position. S5. When carrying a load, hook the hook (30) onto the card seat (9), and use the elastic cord (29) and the second torsion spring (35) to hold the human body during the bounce to increase the training difficulty. When it is necessary to adjust the load-bearing situation, turn the setscrew (27) so that the setscrew (27) disengages from the jack (26), and then turn the turntable (24), thereby changing the torque of the second torsion spring (25). After adjustment, lock the setscrew (27).
