[0018] Example: An adjustable limb nerve rehabilitation device, such as Figures 1-4As shown, the device includes a support base 1, a sliding frame 2, a seat cushion 3, a connecting column 301, a pin 303, a friction wheel 4, a pedal 5, an electric slide rail 6, an electric slider 7, a support block 8, a second friction wheel 9, a crank handle 10, a speed detector 11, a second speed detector 12, a control panel 13, and a locking assembly. The sliding frame 2 is slidably mounted on the upper part of the support base 1, and the connecting column 301 is slidably mounted on the sliding frame 2. The seat cushion 3 is fixedly connected to the upper end of the connecting column 301, and its surface is covered with a soft material, such as high-density sponge or memory foam, to improve patient comfort. The connecting column 301... Three slots 302 are provided on the rear side. A pin 303 is slidably inserted into the upper rear side of the sliding frame 2. The pin 303 is inserted into the corresponding slot 302, thereby locking the position of the connecting post 301 on the sliding frame 2 and fixing the height of the seat cushion 3. The surface of the slot 302 is provided with an elastic deformation pad, such as a thermoplastic elastomer pad or a silicone pad. This elastic deformation pad can elastically compress under radial pressure when the pin 303 is inserted, and after insertion, it applies a clamping force to the outer diameter of the pin 303 through its own restoring force, effectively preventing the pin 303 from axially slipping out during use. 03. A pull ring is provided at the rear end, allowing the patient to manually pull out the pin 303 to adjust the height of the seat cushion 3. Friction wheel 1 4 is rotatably mounted inside the support base 1. A pedal 5 is bolted to both sides of friction wheel 1 4, extending through the support base 1 to its outside for the patient to perform lower limb training. An electric slide rail 6 is bolted to the front of the support base 1, on which an electric slider 7 is slidably mounted. A support block 8 is bolted to the front of the electric slider 7. Friction wheel 2 9 is rotatably mounted on the upper part of the support block 8. A crank handle 10 is fixedly connected to both sides of friction wheel 2 9 for the patient to perform upper limb training. During training, the surface of the crank handle 10 is provided with an anti-slip groove structure to enhance grip stability, prevent hand slippage, and improve training safety. Each pedal 5 is bolted to the end of the friction wheel 4 with a speed detector 11. The center of the friction wheel 9 is bolted to a speed detector 12. The control panel 13 is also bolted to the upper part of the support block 8. The electric slide rail 6, electric slider 7, speed detector 11 and speed detector 12 are all electrically connected to the control panel 13. The friction wheel 9 is located behind the control panel 13. The locking component is set between the support base 1 and the sliding frame 2.
[0019] like Figure 3 and Figure 4As shown, the locking assembly includes a locking bar 14, a pressure plate 1401, a telescopic rod 15, a return spring 16, and a locking block 17. The locking bar 14 is slidably disposed on the upper part of the support base 1. The pressure plate 1401 is fixedly connected to the rear end of the locking bar 14 and located outside the support base 1 for easy operation. Two telescopic rods 15 are symmetrically distributed between the locking bar 14 and the support base 1. The fixed end of the telescopic rod 15 is fixedly connected to the support base 1, and the movable end is fixedly connected to the locking bar 14. A return spring 16 is sleeved on the outside of each telescopic rod 15. The upper and lower ends of the return spring 16 are fixedly connected to the locking bar 14 and the support base 1, respectively, to provide a reset force for the locking bar 14. A locking block 17 is fixedly connected to the upper part of the sliding frame 2. The locking block 17 is inserted into the locking bar 14 to lock the position of the sliding frame 2 on the support base 1.
[0020] When it is necessary to adjust the front and back position of the seat cushion 3, first press down on the pressure plate 1401, which will cause the locking strip 14 to move downward against the elastic force of the return spring 16, so that the locking strip 14 disengages from the locking block 17. As the locking strip 14 moves down, the length of the telescopic rod 15 shortens, and the return spring 16 is compressed. At this time, the sliding frame 2 is no longer restricted by the lock and can slide back and forth along the support seat 1, moving the seat cushion 3 to the appropriate front and back position. After the adjustment is completed, release the pressure plate 1401. Under the reset action of the return spring 16, the locking strip 14 moves upward, so that the locking block 17 is reinserted into the locking strip 14, the length of the telescopic rod 15 is restored, and the position of the sliding frame 2 is locked, thereby achieving a stable fixation of the front and back position of the seat cushion 3.
[0021] If you need to adjust the height of the seat cushion 3, pull the pin 303 backward to disengage it from the current slot 302, then slide the seat cushion 3 up and down to the appropriate height, and then push the pin 303 forward to insert it into the slot 302 of the corresponding height to lock the height of the seat cushion 3.
[0022] When the patient is performing lower limb training, he sits on the cushion 3, holds the crank handle 10 with both hands, and steps on the pedal 5 with both feet to drive the friction wheel 4 to rotate. The speed detector 11 detects the movement speed of the pedal 5 in real time and feeds the data back to the control screen 13.
[0023] When upper limb training is required, the electric slide rail 6 is activated through the control screen 13, and the electric slider 7 is moved up and down, which drives the support block 8 and friction wheel 2 9 to adjust up and down, thereby changing the height of the crank handle 10 to adapt to the range of motion of the patient's upper limb. Then the patient sits on the seat cushion 3, puts his feet on the pedal 5, and holds the crank handle 10 with both hands to perform rotation training. The friction wheel 2 9 drives the speed detector 2 12 to rotate synchronously, and feeds the motion data back to the control screen 13 to realize data monitoring and feedback of the training process.
[0024] Throughout the training process, the control screen 13 monitors parameters such as training time, movement speed, and frequency in real time, making it convenient for patients to keep track of their training status and for doctors to conduct remote assessments and guidance, thereby improving the intelligence and personalization of rehabilitation training.
