Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1

[0030] Please refer to Figure 1-8 , a multifunctional waist training device for dance training, including a bracket 1. A correction mechanism 2 is arranged on the outer side of the bracket 1, and an adjustment mechanism 3 is arranged on the outer side of the bracket 1. The correction mechanism 2 includes two fixed frames 202. Control buttons 307 are fixedly communicated with the side surfaces of the two fixed frames 202 close to each other. Rectangular boxes 201 are fixedly connected to the side surfaces of the two fixed frames 202 away from each other. A fixed seat 207 is fixedly connected to the inner bottom wall of each rectangular box 201. A stepping motor 206 is fixedly connected to the inner wall of each fixed seat 207. A rotating shaft 205 is fixedly connected to the output end of each stepping motor 206. A cross shaft 208 is slidably connected to the inside of each rotating shaft 205. A threaded shaft 203 is fixedly connected to the top end of each cross shaft 208. A lifting plate 204 is rotatably connected to the outer surfaces of the two threaded shafts 203. Two stress springs 210 are fixedly connected to the bottom surface of the lifting plate 204. A rectangular plate 209 is fixedly connected to the bottom ends of the two stress springs 210;

[0031] Two fixed shafts 4 are fixedly connected to the inner wall of the bracket 1. A pedal 5 is fixedly connected to the outer surface of each fixed shaft 4. By providing the fixed shafts 4 and the pedals 5, a position for the user to place the feet can be provided;

[0032] Two limiting cylinders 6 are fixedly connected to the inner wall of the bracket 1. The inner walls of the two fixing frames 202 are jointly fixedly connected to the outer surface of the bracket 1. By providing the limiting cylinders 6, the limiting cylinders 6 can provide limitation for the user's heel, preventing the user from being unbalanced due to the lack of a force application point when using the device;

[0033] A limiting shaft 9 is fixedly connected to the upper surface of each rectangular box 201. The inside of the lifting plate 204 is slidably connected to the outer surfaces of the two limiting shafts 9. By providing the limiting shafts 9, the limiting shafts 9 can prevent the lifting plate 204 from rotating, enabling the lifting plate 204 to only move in the up and down directions;

[0034] Two support plates 11 are fixedly connected to the upper surface of the lifting plate 204. The inner walls of the two support plates 11 are jointly rotatably connected to a rotating shaft 17. A rotating plate 8 is fixedly connected to the outer surface of the rotating shaft 17. By providing the rotating shaft 17, the rotating shaft 17 can drive the rotating plate 8 to rotate. When the rotating plate 8 is subjected to a thrust, it will rotate around the center of the rotating shaft 17;

[0035] A struck plate 7 is fixedly connected to the upper surface of the lifting plate 204. The outer surfaces of each threaded shaft 203 are threadedly connected to the inner wall of the rectangular box 201. By providing the struck plate 7, the struck plate 7 can produce different sounds according to different degrees of the user's kyphosis;

[0036] A striking block 12 is fixedly connected to the upper surface of the rotating plate 8. The outer surface of the striking block 12 is in contact with the bottom surface of the struck plate 7. By providing the striking block 12, the striking block 12 can determine the magnitude of the knocking force applied to the struck plate 7 according to the rotation degree of the rotating plate 8, serving the purpose of warning;

[0037] Two reset springs 15 are fixedly connected to the inner bottom wall of the lifting plate 204. The tops of the two reset springs 15 are jointly fixedly connected to a pressure receiving plate 14. By providing the reset springs 15 and the pressure receiving plate 14, when the pressure receiving plate 14 is subjected to pressure, it will transmit the pressure to the two reset springs 15, thereby driving the two reset springs 15 to contract. The reset spring 15 mainly consists of a spring structure. When an external force acts on the reset spring 15, the reset spring 15 will be compressed, thereby storing elastic potential energy. When the external force disappears or decreases to a certain extent, the reset spring 15 will release the stored energy and restore the pressure receiving plate 14 to its initial position;

[0038] The bottom surface of the rotating plate 8 is fixedly connected with a first ball eye bearing 13, and the outer surface of the first ball eye bearing 13 is in contact with the upper surface of the pressure receiving plate 14. By providing the first ball eye bearing 13, the first ball eye bearing 13 can be used to reduce the friction between the rotating plate 8 and the pressure receiving plate 14, increasing the service life of the equipment. The first ball eye bearing 13 realizes the flexible movement and rotation of an object through the free rotation of large steel balls in the bearing seat. The contact area between the large steel balls and the bearing seat is small, and the friction coefficient is low. Therefore, smooth rotation can be achieved under the action of a small external force;

[0039] The upper surface of the rectangular plate 209 is fixedly connected with a transmission shaft 10, and the top end of the transmission shaft 10 is fixedly connected with a second ball eye bearing 16. The outer surface of the second ball eye bearing 16 is in contact with the bottom surface of the rotating plate 8. By providing the transmission shaft 10 and the second ball eye bearing 16, the transmission shaft 10 can be used to apply the thrust received by the rectangular plate 209 to the rotating plate 8, pushing the rotating plate 8 to rotate around the center of the rotating shaft 17.

[0040] The specific implementation of this embodiment is as follows: After the user lies prone on the adjusted rectangular pad 301, applying pressure to the control button 307 on the right can control the operation of the stepper motor 206. The stepper motor 206 generally consists of two major parts, a stator and a rotor. There are multiple windings on the stator, and these windings are arranged according to a certain rule to form different phases, such as two-phase, three-phase, four-phase, and five-phase, etc. The rotor varies according to different types. Common ones are reactive rotors and permanent magnet rotors. In addition, the stepper motor 206 is an actuator that converts electrical pulse signals into angular displacement or linear displacement. When the stepper driver receives a pulse signal, it drives the stepper motor 206 to rotate a fixed angle in the set direction. This angle is called the step angle. For example, for a stepper motor 206 with a step angle of 1.8 degrees, it will rotate 1.8 degrees every time it receives a pulse signal. Therefore, the rotation angle of the stepper motor 206 is controllable. Using the rotational power generated when the stepper motor 206 operates, the rotating shaft 205 fixed to the output end of the stepper motor 206 can be driven to rotate. When the rotating shaft 205 rotates, the cross shaft 208 slidably connected inside it will also rotate. It should be understood here that the cross shaft 208 is not fixed inside the rotating shaft 205 but slides inside the rotating shaft 205, and the cross structure on the surface of the cross shaft 208 can also well transmit the power when the rotating shaft 205 rotates to the cross shaft 208. Therefore, the cross shaft 208 can rotate while sliding up and down, thereby driving the threaded shaft 203 fixed to the top of the cross shaft 208 to rotate synchronously. With the threaded connection relationship between the threaded shaft 203 and the rectangular box 201, the lifting plate 204 can be driven to move downward by the threaded shaft 203, so that the lifting plate 204 and the rectangular plate 209 are above the user's head, which can ensure that when the user is performing waist training, they will touch the rectangular plate 209 every time they arch their back, achieving the purpose of posture correction. It should be understood here that a layer of rubber is covered on the bottom surface of the rectangular plate 209 to avoid violent impact between the user's head and the rectangular plate 209. And when the user's posture is incorrect and an arching problem occurs, it will push the rectangular plate 209 and the transmission shaft 10 upward, and further push the rotating plate 8 to rotate around the center of the rotating shaft 17, thereby pushing the knocking block 12 and the first bull's-eye bearing 13 downward, prompting the first bull's-eye bearing 13 to squeeze the pressure receiving plate 14 downward, causing the return spring 15 to contract. When the user bends down again, the force spring 210 will push the rectangular plate 209 to reset, thus pushing the rectangular plate 209 to reset. Therefore, the rotating plate 8 will not receive any thrust, so the knocking block 12 and the first bull's-eye bearing 13 will quickly reset under the elastic force of the return spring 15 and knock on the struck plate 7. The louder the knocking sound, the greater the degree of arching.

[0041] Embodiment Two

[0042] Please refer to Figure 1-8, the adjusting mechanism 3 includes a hydraulic rod 304. The outer surface of the hydraulic rod 304 is fixedly connected to the inner wall of the bracket 1. The telescopic end of the hydraulic rod 304 is fixedly connected with a moving block 305. A chute 306 is formed on the upper surface of the bracket 1. The outer surface of the moving block 305 is slidably connected to the inside of the chute 306. The upper surface of the moving block 305 is fixedly connected with a moving plate 302. Two rectangular pads 301 are fixedly connected to the outer surface of the moving plate 302. Handles 303 are fixedly connected to one side surfaces of the two rectangular pads 301 away from each other.

[0043] The specific implementation manner of this embodiment is as follows: When the device needs to be used, the user steps on the two pedals 5 with feet and places the two forearms in the grooves formed on the upper surface of the fixing frame 202. At this time, the two palms need to tightly hold the two grips fixed on the upper surface of the fixing frame 202 to facilitate controlling the two control buttons 307. Subsequently, a thrust needs to be applied to the forearms to make the user's body suspended without contacting the moving plate 302. Then, pressure is applied to the left control button 307. The left control button 307 will control the operation of the hydraulic rod 304. The working principle of the hydraulic rod 304 is based on Pascal's law, that is, the pressure of the enclosed liquid can be evenly transmitted in the liquid, so as to achieve the amplification of force and the change of direction. When high-pressure oil enters one side of the hydraulic cylinder, the piston is subjected to a thrust and drives the piston rod to move. On the contrary, when high-pressure oil enters the other side, the piston moves in the reverse direction. The thrust generated during the operation of the hydraulic rod 304 is used to drive the moving block 305 and the moving plate 302 to move. When the moving plate 302 drives the rectangular pad 301 to move below the user's hip joint, the pressure applied to the left control button 307 can be controlled. At this time, the rectangular pad 301 is located below the hip joint, which is convenient for the user to use.

[0044] Embodiment Three

[0045] Please refer to Figure 1-8, the specific implementation of this embodiment is as follows: When the device needs to be used, the user steps on the two pedals 5 with feet and places the two forearms in the grooves formed on the upper surface of the fixing frame 202. At this time, both palms need to tightly hold the two grips fixed on the upper surface of the fixing frame 202 to facilitate the control of the two control buttons 307. Subsequently, a thrust needs to be applied to the forearms to keep the user's body suspended without contacting the moving plate 302. Then, pressure is applied to the left control button 307. The left control button 307 will control the operation of the hydraulic rod 304. The working principle of the hydraulic rod 304 is based on Pascal's law, that is, the pressure of the enclosed liquid can be evenly transmitted in the liquid, thereby realizing the amplification of force and the change of direction. When high-pressure oil enters one side of the hydraulic cylinder, the piston is subjected to a thrust and drives the piston rod to move. On the contrary, when high-pressure oil enters the other side, the piston moves in the opposite direction. The thrust generated during the operation of the hydraulic rod 304 is used to drive the moving block 305 and the moving plate 302 to move. When the moving plate 302 drives the rectangular pad 301 to move under the user's hip joint, the pressure applied to the left control button 307 can be controlled. At this time, the rectangular pad 301 is located under the hip joint, which is convenient for the user to use. After the user lies on the adjusted rectangular pad 301, pressure is applied to the right control button 307 to control the operation of the stepper motor 206. The stepper motor 206 generally consists of two major parts: a stator and a rotor. There are multiple windings on the stator, and these windings are arranged according to a certain rule to form different phases, such as two-phase, three-phase, four-phase, and five-phase, etc. The rotor varies according to different types. Common types include a reactive rotor and a permanent magnet rotor. In addition, the stepper motor 206 is an actuator that converts an electrical pulse signal into an angular displacement or a linear displacement. When the stepper driver receives a pulse signal, it drives the stepper motor 206 to rotate a fixed angle in the set direction. This angle is called the step angle. For example, for a stepper motor 206 with a step angle of 1.8 degrees, it will rotate 1.8 degrees, so the rotation angle of the stepping motor 206 is controllable. By using the rotational power generated when the stepping motor 206 operates, the rotating shaft 205 fixed to the output end of the stepping motor 206 can be driven to rotate. When the rotating shaft 205 rotates, the cross shaft 208 slidably connected inside it will also rotate. It should be understood here that the cross shaft 208 is not fixed inside the rotating shaft 205, but slides inside the rotating shaft 205, and the cross structure on the surface of the cross shaft 208 can also well transmit the power when the rotating shaft 205 rotates to the cross shaft 208. Therefore, the cross shaft 208 can rotate while sliding up and down, thereby driving the threaded shaft 203 fixed to the top of the cross shaft 208 to rotate synchronously. With the threaded connection between the threaded shaft 203 and the rectangular box 201, the lifting plate 204 can be driven to move downward by the threaded shaft 203, so that the lifting plate 204 and the rectangular plate 209 are above the user's head, which can ensure that when the user is performing waist training, the rectangular plate 209 will be touched every time there is a reverse arch, achieving the purpose of posture correction. It should be understood here that a layer of rubber is covered on the bottom surface of the rectangular plate 209 to avoid violent impact between the user's head and the rectangular plate 209. And when the user's posture is incorrect and there is a reverse arch problem, the rectangular plate 209 and the transmission shaft 10 will be pushed upward, and further the rotating plate 8 will be pushed to rotate around the center of the rotating shaft 17, thereby pushing the knocking block 12 and the first bull's-eye bearing 13 downward, causing the first bull's-eye bearing 13 to squeeze the pressure receiving plate 14 downward, making the return spring 15 contract. When the user bends down again, the force spring 210 will push the rectangular plate 209 to reset, thus pushing the rectangular plate 209 to reset. Therefore, the rotating plate 8 will not receive any thrust, so the knocking block 12 and the first bull's-eye bearing 13 will quickly reset under the elastic force of the return spring 15 and knock on the struck plate 7. The louder the knocking sound, the greater the reverse arch degree.
