[0004] However, this invention uses a single massage method, cannot combine multiple methods to promote blood circulation in the user, has poor flexibility, is inconvenient to adjust the distance of the device to stretch the joint as needed, is difficult to use, and cannot easily adjust the length of the joint stretch in small increments. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the technical solution adopted by this invention is: a massage system for relieving rheumatic joint pain, comprising...

[0006] The upper housing is composed of two semi-circular plates;

[0007] The lower housing is composed of two semi-circular plates;

[0008] A stretching device includes a first motor. Longitudinal grooves are formed on both sides of the inner wall of the upper housing. The first motor is installed inside the longitudinal grooves and is fixedly connected to the inner wall of the longitudinal grooves. The longitudinal grooves penetrate the lower housing and extend into its interior. A rotating disk is fixedly connected to the output end of the first motor. A pusher block is installed on the side of the rotating disk away from the first motor. A pusher plate is slidably connected to the bottom of the pusher block. One top end of the pusher plate is an arc-shaped plate, and one bottom end of the pusher plate extends into the interior of the lower housing and is fixedly connected to it. An elastic rope is installed between the upper and lower housings, with both ends of the elastic rope extending into the interior of the longitudinal grooves and fixedly connected to their inner walls.

[0009] The pressing device includes a rubber block installed on the inner wall of the upper and lower housings. A bracket is fixedly connected to one side of the rubber block, and the end of the bracket away from the rubber block extends into the interior of the upper and lower housings. The bracket is slidably connected to the upper and lower housings, enabling the user's joints to be stretched and kneaded. This promotes blood circulation in the user in multiple ways and treats various rheumatic joint damages.

[0010] Preferably, one side of the upper shell and the lower shell are fixedly connected by straps, and the side of the upper shell and the lower shell away from the straps is fixedly connected with fiber cloth. A first bolt is installed on the end of the fiber cloth away from the upper shell and the lower shell. An internal thread groove is opened on the side of the upper shell and the lower shell near the first bolt. The first bolt passes through the fiber cloth and is threadedly connected to the internal thread groove.

[0011] Preferably, a positioning groove is provided on the side of the rotating disk away from the first motor, and a positioning plate is installed on the side of the rotating disk close to the positioning groove. The pusher block is fixedly connected to the positioning plate, and the positioning plate extends into the interior of the positioning groove and is slidably connected to the positioning groove. A second bolt is installed on the side of the positioning plate away from the rotating disk, which improves the flexibility of the equipment and allows the distance of the equipment's extension joint to be adjusted as needed.

[0012] Preferably, an elastic sheet is fixedly connected to the bottom of the pusher block, and a contact block is fixedly connected to the end of the elastic sheet away from the pusher block. The bottom of the pusher block is concave, and a third bolt is installed on one side of the pusher block. The third bolt passes through the pusher block and extends to the outside of the pusher block, which improves the buffering capacity of the equipment, avoids damage caused by excessive tension when the joint is stretched, and allows for convenient small-amplitude adjustment of the joint stretching length, reducing the difficulty of using the equipment.

[0013] Preferably, the inner walls of both the upper and lower housings are provided with grooves that are adapted to the bracket. A second motor is fixedly connected to one side of the inner wall of the groove, and an elliptical cylinder is fixedly connected to the output end of the second motor. The elliptical cylinder is slidably connected to the bracket.

[0014] Preferably, a control groove is provided on one side of the rubber block, and a traction belt is fixedly connected to the end of the inner wall of the control groove away from the second motor, and one end of the traction belt extends to the outside of the rubber block.

[0015] Preferably, a winding rod is fixedly connected to the output end of the second motor. The elliptical cylinder is fixedly connected to the winding rod. A magnet groove is provided on the outer side of the winding rod, and a magnet block is installed inside the magnet groove. An elastic plate is fixedly connected to the outer side of the winding rod between the magnet blocks. A groove is provided at the end of the elastic plate away from the winding rod. A wear-resistant plate is fixedly connected to the side of the traction belt near the winding rod, and a metal block is fixedly connected to one side of the wear-resistant plate. This allows the device to rub the user's skin during the pressing process, increasing the diversity of the device's massage methods.

[0016] Preferably, a push plate is installed inside the control slot at the end away from the second motor, and a pressing rod is fixedly connected to the side of the push plate away from the second motor. The pressing rod extends through the outside of the rubber block and is slidably connected to the rubber block, which can massage the user in multiple ways through small-range pressing of the pressing rod and large-range pressing of the rubber block, thereby enhancing the massage effect.

[0017] Preferably, a metal spring is fixedly connected to the side of the push plate away from the pressing rod, and the end of the metal spring away from the push plate is fixedly connected to the inner wall of the control groove. Arc-shaped plates are fixedly connected to both sides of the inner wall of the control groove. The arc-shaped plates are elastic plates, and the push plate is slidably connected to the arc-shaped plates. This allows for the selection of a single massage mode or a combination of multiple modes as needed, to meet the needs of different users.

[0018] This invention provides a massage system for relieving rheumatic joint pain. It has the following beneficial effects:

[0019] 1. This massage system for relieving rheumatic joint pain uses a first motor to drive a rotating disc, which in turn drives a pusher block to rotate. The rotating disc pushes the pusher plate away from the upper housing, and the pusher plate pushes the lower housing away from the upper housing. As the distance between the upper and lower housings increases, it pulls the user's joints to the sides. The rubber block kneads the muscles near the user's joints, which can stretch and knead the user's joints, promoting blood circulation in the user in multiple ways and treating various rheumatic joint damages.

[0020] 2. This massage system for relieving rheumatic joint pain, by inserting a positioning plate into the positioning slots at different positions on the rotating disk, and rotating the second bolt to fix the positioning plate on the rotating disk, the lower housing is pushed away from the upper housing by the pusher plate during the rotation of the rotating disk, which improves the flexibility of the equipment and can adjust the distance of the joint stretching as needed.

[0021] 3. This massage system for relieving rheumatic joint pain utilizes a third bolt. Rotating the third bolt pushes a bent elastic plate away from the bolt, gradually reducing its bending degree. The contact block is then pushed away from the pusher block. As the rotating disc rotates, the extended contact block at the bottom pushes the lower housing a greater distance. During the pusher block's movement, the elastic plate is compressed and bent for cushioning, improving the device's buffering capacity. This prevents excessive tension during joint stretching, avoiding damage, and allows for convenient, small-amplitude adjustments to the joint stretching length, reducing the difficulty of using the device.

[0022] 4. This massage system for relieving rheumatic joint pain uses a second motor to drive an elliptical cylinder to rotate. The elliptical cylinder pushes a support frame to move outwards from the upper and lower housings. The rubber block is pushed by the support frame to press against the user. The pressing rod first contacts the user, stimulating their nerves. The pressing rod pushes a push plate, squeezing and bending a metal spring sheet, which then moves inwards towards the control groove. When the pressing rod is not fully inside the rubber block, the second motor rotates in the opposite direction. At this point, the rubber block is only used for pressing the pressing rod to stimulate the user's nerves. Increasing the rotation angle of the second motor allows the pressing rod to be fully pressed into the rubber block by the user. The rubber block is then pushed by the support frame to continue pressing against the user. This system can massage the user in multiple ways, including small-range pressing with the pressing rod and large-range pressing with the rubber block, thus enhancing the massage effect.

[0023] 5. This massage system for relieving rheumatic joint pain works by having a metal block attracted to a winding rod by a magnet. The winding rod is rotated by a second motor, and an elastic plate pushes a wear-resistant plate and the metal block to rotate with the winding rod. The wear-resistant plate pulls a rubber block to one side via a traction belt, causing the wear-resistant plate to bend. When the elastic plate bends too much, the wear-resistant plate slides off the elastic plate and is no longer blocked. The rubber block moves back in its initial direction due to its own elasticity. Then, the wear-resistant plate and the metal block are caught by another elastic plate below, and the metal block again attracts the wear-resistant plate to the magnet. This allows the device to rub the user's skin while pressing on the user, increasing the diversity of massage methods.

[0024] 6. This massage system for relieving rheumatic joint pain allows users to manually push a push plate towards an arc-shaped plate, which then bends the arc-shaped plate. The push plate is then moved to the side of the arc-shaped plate closest to the support, where it is blocked by the arc-shaped plate. The pressing rod then fully enters the rubber block. Users can select a single massage mode or a combination of multiple modes as needed to meet the needs of different groups. Attached Figure Description

[0035] Example 1

[0036] Please see Figures 1-6 This invention provides a technical solution: a massage system for relieving rheumatic joint pain, comprising...

[0037] Upper shell 1, which is composed of two semi-circular plates;

[0038] Lower shell 2, which consists of two semi-circular plates;

[0039] The stretching device 3 includes a first motor 301. The inner walls of the upper housing 1 are provided with longitudinal grooves 304 on both sides. The first motor 301 is installed inside the longitudinal grooves 304 and is fixedly connected to the inner wall of the longitudinal grooves 304. The longitudinal grooves 304 penetrate the lower housing 2 and extend into the interior of the lower housing 2. The output end of the first motor 301 is fixedly connected to a rotating disk 302. A pusher block 303 is installed on the side of the rotating disk 302 away from the first motor 301. A pusher plate 305 is slidably connected to the bottom of the pusher block 303. One end of the top of the pusher plate 305 is an arc-shaped plate. One end of the bottom of the pusher plate 305 extends into the interior of the lower housing 2 and is fixedly connected to the lower housing 2. An elastic rope 306 is installed between the upper housing 1 and the lower housing 2. Both ends of the elastic rope 306 extend into the interior of the longitudinal grooves 304 and are fixedly connected to the inner wall of the longitudinal grooves 304.

[0040] Pressing device 4 includes a rubber block 401, which is installed on the inner wall of the upper housing 1 and the lower housing 2. A bracket 402 is fixedly connected to one side of the rubber block 401. The end of the bracket 402 away from the rubber block 401 extends into the interior of the upper housing 1 and the lower housing 2, and the bracket 402 is slidably connected to the upper housing 1 and the lower housing 2.

[0041] One side of the upper shell 1 and the lower shell 2 are fixedly connected by straps 5. Fiber cloth 6 is fixedly connected to the side of the upper shell 1 and the lower shell 2 away from the straps 5. A first bolt 7 is installed at the end of the fiber cloth 6 away from the upper shell 1 and the lower shell 2. An internal thread groove 8 is opened on the side of the upper shell 1 and the lower shell 2 near the first bolt 7. The first bolt 7 passes through the fiber cloth 6 and is threadedly connected to the internal thread groove 8.

[0042] A positioning groove 9 is provided on the side of the rotating disk 302 away from the first motor 301. A positioning plate 10 is installed on the side of the rotating disk 302 close to the positioning groove 9. The pusher block 303 is fixedly connected to the positioning plate 10. The positioning plate 10 extends into the interior of the positioning groove 9 and is slidably connected to the positioning groove 9. A second bolt 11 is installed on the side of the positioning plate 10 away from the rotating disk 302.

[0043] An elastic sheet 12 is fixedly connected to the bottom of the pusher block 303. A contact block 13 is fixedly connected to the end of the elastic sheet 12 away from the pusher block 303. The bottom of the pusher block 303 is concave. A third bolt 14 is installed on one side of the pusher block 303. The third bolt 14 passes through the pusher block 303 and extends to the outside of the pusher block 303.

[0044] The inner walls of the upper housing 1 and the lower housing 2 are both provided with grooves that are adapted to the bracket 402. A second motor 15 is fixedly connected to one side of the inner wall of the groove. An elliptical cylinder 16 is fixedly connected to the output end of the second motor 15. The elliptical cylinder 16 is slidably connected to the bracket 402.

[0045] In use, remove the first bolt 7, open the upper shell 1 and then the lower shell 2 and place them on the upper and lower sides of the joint. The upper shell 1 and the lower shell 2 stretch the elastic rope 306 to the normal length. Then close the upper shell 1 and the lower shell 2. The first bolt 7 rotates into the internal thread groove 8 to fix the upper shell 1 and the lower shell 2 at the user's joint. The first motor 301 drives the rotating disk 302 to rotate, and the pusher block 303 is driven to rotate. When the pusher block 303 moves to the bottom of the rotating disk 302, the rotating disk 302 pushes the pusher plate 305 to move away from the upper shell 1. The pusher plate 305 pushes the lower shell 2 to move away from the upper shell 1. As the distance between the upper shell 1 and the lower shell 2 increases, it pulls the user's joint to stretch to both sides. During the mutual movement of the upper shell 1 and the lower shell 2, the rubber block 401 moves. The rubber block 401 rubs the muscles near the user's joint, which can stretch and rub the user's joint, promote blood circulation in the user in multiple ways, and treat various rheumatic joint damage.

[0046] The positioning plate 10 is inserted into the positioning slots 9 at different positions of the rotating disk 302. The second bolt 11 is rotated to fix the positioning plate 10 on the rotating disk 302. During the rotation of the rotating disk 302, the lower housing 2 is pushed away from the upper housing 1 by the pusher plate 305, which improves the flexibility of the equipment and allows the distance of the equipment's extension joint to be adjusted as needed.

[0047] Rotating the third bolt 14 pushes the bent elastic plate 12 away from the third bolt 14, and the degree of bending of the elastic plate 12 gradually decreases. The contact block 13 is pushed by the elastic plate 12 away from the pusher block 303. As the pusher block 303 rotates with the rotating disk 302, the extended contact block 13 at the bottom can push the lower housing 2 to move a greater distance. During the process of the pusher block 303 pushing the pusher plate 305 to move, the elastic plate 12 is squeezed and bent to buffer, which improves the buffering capacity of the equipment, avoids damage caused by excessive tension when the joint is stretched, and allows for convenient small-amplitude adjustment of the joint stretching length, reducing the difficulty of using the equipment.

[0048] Example 2

[0049] Please see Figures 1-8 The present invention provides a technical solution: Based on embodiment 1, a control groove 17 is provided on one side of the rubber block 401, and a traction belt 18 is fixedly connected to the end of the inner wall of the control groove 17 away from the second motor 15, and one end of the traction belt 18 extends to the outside of the rubber block 401.

[0050] The output end of the second motor 15 is fixedly connected to a winding rod 19. An elliptical cylinder 16 is fixedly connected to the winding rod 19. A magnet groove 20 is provided on the outer side of the winding rod 19. A magnet block 21 is installed inside the magnet groove 20. An elastic plate 22 is fixedly connected on the outer side of the winding rod 19 between the magnet blocks 21. A groove is provided at the end of the elastic plate 22 away from the winding rod 19. A wear-resistant plate 23 is fixedly connected to the side of the traction belt 18 near the winding rod 19. A metal block 24 is fixedly connected to one side of the wear-resistant plate 23.

[0051] A push plate 25 is installed inside the control slot 17 at the end away from the second motor 15. A pressing rod 26 is fixedly connected to the side of the push plate 25 away from the second motor 15. The pressing rod 26 extends through to the outside of the rubber block 401 and is slidably connected to the rubber block 401.

[0052] A metal spring 27 is fixedly connected to the side of the push plate 25 away from the pressing rod 26. The end of the metal spring 27 away from the push plate 25 is fixedly connected to the inner wall of the control groove 17. Arc plates 28 are fixedly connected to both sides of the inner wall of the control groove 17. The arc plates 28 are elastic plates. The push plate 25 and the arc plates 28 are slidably connected.

[0053] In use, the second motor 15 drives the elliptical cylinder 16 to rotate, and the elliptical cylinder 16 pushes the bracket 402 to move outward from the upper housing 1 and the lower housing 2. The rubber block 401 is driven by the bracket 402 to squeeze the user. The pressing rod 26 first contacts the user and presses to stimulate the user's nerves. The pressing rod 26 pushes the push plate 25 to squeeze and bend the metal spring 27 and move it towards the inside of the control groove 17. When the pressing rod 26 is not fully inside the rubber block 401, the second motor 15 rotates in the opposite direction. At this time, the rubber block 401 is only used for pressing the pressing rod 26 to stimulate the user's nerves. The rotation angle of the second motor 15 is increased, and the pressing rod 26 is squeezed by the user to fully enter the rubber block 401. The rubber block 401 is pushed by the bracket 402 to continue pressing the user. It can massage the user in multiple ways through the small range of pressing of the pressing rod 26 and the large range of pressing of the rubber block 401, which enhances the massage effect.

[0054] Metal block 24 is attracted to the winding rod 19 by magnet block 21. The winding rod 19 is driven to rotate by the second motor 15. Elastic plate 22 pushes wear-resistant plate 23 and metal block 24 to rotate with the winding rod 19. Wear-resistant plate 23 pulls rubber block 401 to one side through traction belt 18. Wear-resistant plate 23 pushes elastic plate 22 to bend. When the degree of bending of elastic plate 22 is too large, wear-resistant plate 23 slides over elastic plate 22 and is no longer blocked by elastic plate 22. Rubber block 401 moves in the initial direction due to its own elasticity. Then wear-resistant plate 23 and metal block 24 are caught by another elastic plate 22 below. Metal block 24 attracts wear-resistant plate 23 to magnet block 21 again. It can rub the user's skin during the process of the device pressing the user, which improves the diversity of the device's massage mode.

[0055] Manually push the push plate 25 towards the arc plate 28. The push plate 25 will squeeze and bend the arc plate 28. Then, the push plate 25 will move to the side of the arc plate 28 that is close to the bracket 402. At this time, the push plate 25 will be blocked by the arc plate 28. The pressing rod 26 will be fully inserted into the rubber block 401. It is possible to select a single massage mode or a combination of multiple modes as needed to meet the needs of different users.

[0056] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
