[0017] Please see Figures 1-5 A training frame for hemiplegic upper limbs, comprising: Frame structure 1, a support made of steel structure, and bolted to a designated location on the ground; The rehabilitation training structure 2 is bolted to the upper end of the frame structure 1; The seating structure 3 is bolted to the lower right side of the frame structure 1 and is driven by the internal structure of the frame structure 1. The frame structure 1 includes a support column 11, the lower end of which is connected to a base with a large grounding area by bolts, and is fixed to the ground with the base and bolts. The rehabilitation training structure 2 includes a mounting plate 21, which is bolted to the upper end of the support column 11. A bevel gear box 22 is bolted to the right side of the upper surface of the mounting plate 21. The bevel gear box 22 contains two meshing bevel gears, with the lower end of the shaft of one bevel gear fixed to the upper end of a rotating rod 23. The rotating rod 23 consists of two rods connected by threads, allowing for length adjustment. The lower end of the rotating rod 23 is fixed to a swing arm 24. A groove is formed along the path at the center of the swing arm 24, and a support rod 25 is provided inside the groove for sliding constraint. A return spring 241 is fixedly installed on one side of 5. One end of the return spring 241 is fixed on the inner wall of the return spring 241, thereby limiting and resetting the sliding of the support rod 25. The shaft end of another bevel gear inside the bevel gear box 22 is fixed to the rotating shaft of the spool 26. The spool 26 is rotatably mounted on the upper surface of the mounting plate 21 in cooperation with the bearing seat 27 fixed on the upper surface of the mounting plate 21. The spool 26 has a double pulley structure, and each pulley has a pull rope 28 wound and bound inside. The lower end of the pull rope 28 passes downward through the mounting plate 21 and the upper end plate of the support column 11 and connects to the internal structure of the seating structure 3. The seating structure 3 includes a seat 31, which is fixed to the lower right side of the support column 11 by an integrated triangular frame and bolts. The seat 31 is designed with a height and length based on the average adult height. Pull-out slides 311 are provided inside the front and rear frames of the upper crossbar of the seat 31, and pull-out slide rods 324 are slidably installed inside each pull-out slide 311. One end of each pull-out slide rod 324 extending out of the pull-out slide 311 is fixedly connected to a leg ring 32. An annular liquid channel 321 is provided on the outer ring side inside the leg ring 32, and several through-holes in a U-shape are provided annularly from the liquid channel 321 toward the axis. A piston rod 322 is slidably sealed inside each through-hole. A hydraulic spring is fitted onto the proximal side of the annular plate integrally formed by the piston rod 322. 323, and one end of the hydraulic spring 323 is pressed and fixed to the inner wall of the U-shaped through hole. After the safety liquid is introduced into the annular liquid channel 321 through the liquid valve set on the side of the leg ring 32, the centripetal end of the piston rod 322 will pass out through the U-shaped through hole and contact the thigh of the human lower limb. The lower end of the pull rope 28 will pass out into a pull slide 311 and be fixed to the end of the pull rod 324 inside the pull slide 311. In this way, the pull rod 324 and the leg ring 32 are pulled and driven by the pull wheel 26. Inside the pull slide 311, a pull spring 312 is fixedly set at the opposite end of the pull rod 324 connected to the pull rope 28, and one end of the pull spring 312 is fixed to the end wall of the pull slide 311.

[0018] During the procedure, the patient sits in seat 31 with both legs inserted into leg rings 32. The amount of safe liquid in the annular liquid channel 321 is adjusted via a liquid valve, allowing the piston rod 322 to conform to the thighs and the pressure to be adjusted as needed. Next, the patient adjusts the length of the rotating rod 23 and grasps the handrail 25 in the slide groove of the swing arm 24 to perform upper limb rehabilitation training. When the handrail 25 is pushed to both sides, the rotating rod 23 rotates, which is transmitted through the bevel gear box 22, causing the reel 26 to wind up the pull rope 28, pulling the pull slide rod 324 to slide in the pull slide 311, compressing the pull spring 312, and simultaneously moving the leg ring 32 along the lower limbs. The piston rod 322 provides a sliding massage to the patient's lower limbs, assisting blood circulation and aiding subsequent rehabilitation.

[0019] In summary, through the linkage design of rehabilitation training structure 2 and seating structure 3, when the patient pushes the handrail 25 to perform upper limb activities, the rotating rod 23 rotates and is transmitted through the bevel gear box 22, causing the thread wheel 26 to wind up the pull rope 28, which in turn pulls the leg ring 32 along the lower limb. The piston rod 322 provides sliding massage to the lower limb, achieving synergy between upper limb training and lower limb blood circulation promotion. The active movement of the upper limb can help the patient restore the strength, coordination, and flexibility of the upper limb, while the sliding massage of the lower limb through the piston rod 322 can help promote blood circulation in the lower limb, preparing for subsequent lower limb rehabilitation training. This multi-site synergistic rehabilitation training method helps to comprehensively improve the patient's motor function. Compared with traditional acupuncture, massage, and other treatment methods, it can conduct rehabilitation training more systematically and regularly, shorten the treatment cycle, and reduce costs.

[0020] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0021] Working principle: During operation, the patient first sits on seat 31 and inserts both legs into the leg ring 32. Then, according to the patient's lower limb size, safe liquid is introduced into the annular liquid channel 321 through the liquid valve on the side of the leg ring 32. Under the pressure of the safe liquid, the centripetal end of the piston rod 322 compresses the hydraulic spring 323, which passes through the U-shaped through hole and contacts the thigh of the lower limb (the contact pressure is adjusted according to the patient's experience). Subsequently, the patient can adjust the length of the rotating rod 23 according to their own limb condition. After adjustment, the patient holds the handrail 25 in the slide groove of the swing arm 24 with both hands and can perform multi-mode rehabilitation training of the upper limb by pushing the handrail 25 to the sides and pushing and pulling the handrail 25 back and forth. When the handrail 25 is pushed to both sides, the handrail 25 will drive the rotating rod 23 to rotate through the swing arm 24. The rotating rod 23 will cooperate with the bevel gear box 22. Through the transmission of two meshing bevel gears, the spool 26 connected to the shaft end of another bevel gear will start to rotate under the support of the bearing seat 27 of the mounting plate 21. Then the rotating spool 26 will wind up the pull rope 28. The wound pull rope 28 will pull the pull slide rod 324 to slide along the pull slide 311. At this time, the pull spring 312 inside the pull slide 311 will undergo elastic deformation due to the pull of the pull slide rod 324. The moving pull slide rod 324 will simultaneously drive the leg ring 32 to move along the lower limb. By using the piston rod 322 inside the leg ring 32, the patient's lower limb will be massaged during the sliding process. In this way, while rehabilitation training, the lower limb blood circulation massage can also be assisted, preparing for subsequent lower limb rehabilitation training. After rehabilitation training is completed, the rotating rod 23, the support rod 25, and the piston rod 322 need to be returned to their initial positions to facilitate their use with the next patient.
