[0015] Working principle: When in use, the user lies flat above the lower body cushion plate and the front end cushion plate. The lower body of the user is fixed by the lower body strap, and the upper body of the user is fixed by the upper body strap. At this time, the user's feet are placed outside the footrest and apply pressure to the footrest. The footrest moves outward and pulls the rear end sliding frame to move outward and slide inside the bed body, prompting the first rack to move and slide on the inner wall of the bed body and causing the first return spring to be stressed and contract and slide on the outer wall of the first limiting post. Furthermore, the first circular gear drives the second rack to move outward and slide on the inner wall of the bed body and causes the second return spring to be stressed and contract, and the front end cushion plate is pushed outward by the front end sliding frame, so as to stretch the upper body, widen the vertebral space, and reduce the compression of the intervertebral disc. In this process, the stretching force of the upper body completely depends on the leg strength of the user. The user can flexibly adjust the magnitude of the exerted force through the legs according to their own physical conditions and feelings.

[0016] During the movement of the front end cushion plate, the front end cushion plate drives the second circular gear to move through the second rotating column. Since the second circular gear is meshed with the third rack fixedly connected to the upper surface of the bed body, during the movement of the second circular gear, it rotates. When the second circular gear rotates, it drives the massage roller to rotate through the second rotating column to massage the back of the user, which can relieve muscle tension, promote local blood circulation, and improve the treatment effect and the favorability of the user experience.

[0017] When it is necessary to maintain a fixed stretching force, only need to move the pulling column upward to prompt the clamping column to move upward and slide inside the second fixing block and cause the adjusting spring II to be stressed and contract. Then move the adjusting disc outward to prompt the adjusting disc to slide on the outer walls of the third rotating column and the limiting block. When the adjusting disc moves to a position where the clamping column can align with the limiting hole, keep the position of the adjusting disc fixed, and then stop pulling the pulling column. Furthermore, the adjusting spring II in the contracted state rebounds and resets to push the clamping column downward to slide into the inner wall of the limiting hole, so as to ensure that the first rotating column will not rotate. Furthermore, the fixed stretching force and the stretching force controlled by oneself can be selected according to needs to treat cervical and lumbar intervertebral disc herniation.

[0018] The present invention provides a device for preventing and treating cervical and lumbar intervertebral disc herniation. It has the following beneficial effects:

[0019] 1. In the present invention, the stretching force of the upper body completely depends on the user's leg strength. The user can flexibly adjust the magnitude of the force exerted by the legs according to their own physical condition and feelings, so as to precisely control the stretching force of the upper body. This can not only ensure that the stretching reaches an effective treatment intensity but also avoid secondary injuries caused by excessive stretching, thereby improving the safety and effectiveness of the treatment.

[0020] 2. During the process of moving through the second circular gear in the present invention, rotation occurs. When the second circular gear rotates, it drives the massage roller to rotate through the second rotating column to massage the user's back, which can relieve muscle tension, promote local blood circulation, and improve the treatment effect and the user experience.

[0021] 3. In the present invention, by adjusting the second spring to move downward and slide to the inner wall of the limit hole, it is ensured that the first rotating column does not rotate. Furthermore, the stretching force can be fixed or controlled by the user as needed for the treatment of cervical and lumbar disc herniation. The stretching method can be flexibly adjusted according to needs, further strengthening the adaptability and functional recovery of the muscles, improving muscle strength and endurance, better maintaining the stability of the spine, and preventing the recurrence of cervical and lumbar disc herniation.

[0030] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. 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.

[0031] Please refer to the attached Figure 1 - attached Figure 5 , the embodiment of the present invention provides a device for preventing and treating cervical and lumbar intervertebral disc herniation, including a bed body 1. A first rotating column 2 is rotatably connected inside the bed body 1. A first circular gear 3 is fixedly connected to the outer wall of the first rotating column 2. The tooth end of the first circular gear 3 is meshed with a first rack 4. The outer wall of the first rack 4 slides on the inner wall of the bed body 1. A rear sliding frame 5 is fixedly connected to the outer wall of the first rack 4. The outer wall of the rear sliding frame 5 slides inside the bed body 1. A foot pedal 6 is arranged on the outer wall of the rear sliding frame 5. The tooth end of the first circular gear 3 is meshed with a second rack 7. The outer wall of the second rack 7 slides on the inner wall of the bed body 1. A front sliding frame 8 is fixedly connected to the outer wall of the second rack 7. The outer wall of the front sliding frame 8 slides inside the bed body 1. A front cushion plate 9 is fixedly connected to the upper surface of the front sliding frame 8. An upper body strap 12 is fixedly connected to the upper surface of the front cushion plate 9. A lower body cushion plate 10 is fixedly connected to the upper surface of the bed body 1. A lower body strap 11 is fixedly connected to the upper surface of the lower body cushion plate 10. A first sliding groove 13 is opened on the outer wall of the first rack 4. A second sliding groove 14 is opened on the outer wall of the second rack 7. A reset assembly is arranged inside the bed body 1. A massage assembly is arranged inside the front cushion plate 9.

[0032] Specifically, the lower body strap 11 is used to fix the user's lower body, and the upper body strap 12 is used to fix the user's upper body. After the upper and lower bodies of the user are fixed, the user can exert force on the footrest 6 with their legs to prompt the rear sliding frame 5 to move outward and slide inside the bed body 1, driving the first rack 4 to move outward and slide on the inner wall of the bed body 1. Thereby, the first circular gear 3 rotates and drives the first rotating column 2 to rotate inside the bed body 1, causing the second rack 7 to be driven to move outward and slide on the inner wall of the bed body 1 and push the front sliding frame 8 to slide outward inside the bed body 1. Furthermore, the front cushion plate 9 moves outward. Since the user's upper body is fixed by the upper body strap 12, the outward movement of the front cushion plate 9 realizes the stretching of the upper body, which can widen the vertebral space and reduce the compression on the intervertebral disc. During this process, the reset component is used to provide the counter-tension for training and treatment and play a reset role. It is the core component for the user to flexibly adjust the magnitude of the exerted force according to their own physical condition and feelings. At the same time, the massage component plays an auxiliary role and can massage the user's back well during operation, which is beneficial to relieving muscle tension and promoting local blood circulation.

[0033] Please refer to the attached Figure 1 - attached Figure 4 The reset component includes a first limit post 15. The outer wall of the first limit post 15 is fixedly connected inside the bed body 1. The outer wall of the first limit post 15 is slidably connected to the inner wall of the first sliding groove 13. A first reset spring 16 is slidably connected to the outer wall of the first limit post 15. One end of the first reset spring 16 is fixedly connected inside the bed body 1, and the other end of the first reset spring 16 is fixedly connected to the outer wall of the first rack 4. The reset component further includes a second limit post 17. The outer wall of the second limit post 17 is fixedly connected inside the bed body 1. The outer wall of the second limit post 17 is slidably connected to the inner wall of the second sliding groove 14. A second reset spring 18 is slidably connected to the outer wall of the second limit post 17. One end of the second reset spring 18 is fixedly connected inside the bed body 1, and the other end of the second reset spring 18 is fixedly connected to the outer wall of the second rack 7.

[0034] Specifically, when a thrust is applied to the footrest 6, the rear sliding carriage 5 drives the first rack 4 to slide and move outward along the inner wall of the bed body 1. During this process, the outer wall of the first limit post 15 slides along the inner wall of the first sliding groove 13 formed on the outer wall of the first rack 4, and at the same time, the first return spring 16 is forced to contract. The first limit post 15 can play a good guiding role in the contraction of the first return spring 16, preventing the first return spring 16 from becoming unstable during the contraction process and improving stability. During the passive outward movement of the second rack 7, the outer wall of the second limit post 17 is passively slid along the inner wall of the second sliding groove 14 formed on the outer wall of the second rack 7, and the second return spring 18 is forced to contract. The second limit post 17 can play a guiding role in the contraction of the second return spring 18, preventing the second return spring 18 from becoming unstable during the contraction process.

[0035] Please refer to the attached Figure 1 and the attached Figure 5 , the massage assembly includes a second rotating column 21. The outer wall of the second rotating column 21 is rotatably connected inside the front cushion plate 9. A massage roller 22 is fixedly connected to the outer wall of the second rotating column 21, and a second circular gear 20 is fixedly connected to the outer wall of the second rotating column 21. The tooth end of the second circular gear 20 is meshed and connected with a third rack 19, and the lower surface of the third rack 19 is fixedly connected to the upper surface of the bed body 1.

[0036] Specifically, during the movement of the front cushion plate 9, the front cushion plate 9 drives the second circular gear 20 to move through the second rotating column 21. Since the second circular gear 20 is meshed and connected with the third rack 19 fixedly connected to the upper surface of the bed body 1, during the movement of the second circular gear 20, it rotates. When the second circular gear 20 rotates, it drives the massage roller 22 to rotate through the second rotating column 21 to massage the user's back.

[0037] Please refer to the attached Figure 1 and the attached Figure 5 , a sliding block 23 is fixedly connected to the lower surface of the front cushion plate 9. A slide rail 24 is slidably connected inside the sliding block 23, and the lower surface of the slide rail 24 is fixedly connected to the upper surface of the bed body 1.

[0038] Specifically, the sliding block 23 and the slide rail 24 mainly play a role in limiting the front cushion plate 9 and improving the smoothness of the movement of the front cushion plate 9.

[0039] Please refer to the attached Figure 1 、the attached Figure 6 and the attached Figure 7, a first-stage rotating column 2 has an internally fixedly connected bevel gear 25 on its inner wall. The tooth end of the bevel gear 25 is meshed with a second-stage bevel gear 26. The inner wall of the second-stage bevel gear 26 is fixedly connected to a third-stage rotating column 27. The outer wall of the third-stage rotating column 27 is rotatably connected to a first fixing block 28, and the upper surface of the first fixing block 28 is fixedly connected to the lower surface of the bed body 1. The outer wall of the third-stage rotating column 27 is slidably connected to an adjusting disc 29, and a limiting hole 30 is formed on the outer wall of the adjusting disc 29. A circular block 33 is fixedly connected to the outer wall of the third-stage rotating column 27, and a limiting block 31 is fixedly connected to the outer wall of the third-stage rotating column 27. One end of the circular block 33 close to the third-stage rotating column 27 is fixedly connected to a first adjusting spring 32, and the other end of the first adjusting spring 32 is fixedly connected to one end of the adjusting disc 29 close to the circular block 33. The outer wall of the first adjusting spring 32 is slidably connected to the outer wall of the limiting block 31, and the outer wall of the limiting block 31 is slidably connected to the inside of the adjusting disc 29. A second fixing block 34 is fixedly connected to the outer wall of the bed body 1. A clamping column 35 is slidably connected to the inside of the second fixing block 34. The top end of the clamping column 35 is fixedly connected to a pulling column 36. The outer wall of the clamping column 35 is slidably and fixedly connected to a top block 38. The outer wall of the clamping column 35 is slidably connected to a second adjusting spring 37. One end of the second adjusting spring 37 is fixedly connected to the lower surface of the second fixing block 34, and the other end of the second adjusting spring 37 is fixedly connected to the top end of the top block 38. The outer wall of the clamping column 35 is slidably connected to the inner wall of the limiting hole 30.

[0040] Specifically, the mutual cooperation between the bevel gear 25 and the second-stage bevel gear 26 can drive and change the direction of rotation of the first-stage rotating column 2. When the first-stage rotating column 2 rotates, the first-stage rotating column 2 drives the bevel gear 25 to rotate, which in turn causes the second-stage bevel gear 26 to rotate and drives the third-stage rotating column 27 to rotate inside the first fixing block 28. Through the limiting block 31 fixedly connected to the outer wall of the third-stage rotating column 27, the adjusting disc 29 can not only rotate with the third-stage rotating column 27 but also slide on the outer wall of the third-stage rotating column 27, which facilitates the adjustment of the adjusting disc 29. At the same time, through the pushing action of the first adjusting spring 32 on the adjusting disc 29, it can be ensured that the clamping column 35 will not slide into the inner wall of the limiting hole 30 during use, which may affect the use. The clamping column 35 can limit the adjusting disc 29, and thus can keep the first-stage rotating column 2 stationary. Specifically, move the pulling column 36 upward to drive the clamping column 35 to move upward and slide inside the second fixing block 34, causing the second adjusting spring 37 to be compressed. Then move the adjusting disc 29 outward to make the adjusting disc 29 slide on the outer walls of the third-stage rotating column 27 and the limiting block 31, causing the first adjusting spring 32 to be compressed. When the bevel gear 25 aligns with the inner wall of the limiting hole 30 formed on the outer wall of the adjusting disc 29, stop pulling the pulling column 36. Then, the compressed second adjusting spring 37 rebounds and pushes the top block 38 to drive the clamping column 35 to move downward and slide inside the limiting hole 30 to lock the adjusting disc 29.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
