Description

Technical Field

[0001] This invention relates to the field of rehabilitation equipment technology, specifically to an assistive upper limb arm strength rehabilitation device after brain disease surgery. Background Technology

[0002] Rehabilitation equipment primarily assists patients in passive movement and daily activities, promoting rehabilitation. Most are made of stainless steel, iron, plastic, or wood, manufactured through processes such as machining, welding, and injection molding to create the necessary parts, which are then assembled. The design tends towards intelligent operation, meeting the needs of patients' daily upper and lower limb movements. Simultaneously, therapists can use some equipment to perform passive movements or manual training on the patient's limbs. Patients can also use the equipment for self-training or training under the guidance of a therapist.

[0003] However, existing rehabilitation equipment, especially devices for upper limb strength recovery, often have some technical problems during use. For example, when patients who need wheelchair-assisted exercise after brain surgery are training independently, although the wheels of the wheelchair can be fixed before use to keep them stationary, it is still inevitable that the upper part of the wheelchair may tilt backward due to excessive force or other accidents during the pulling process of the patient exercising the upper limbs, which may affect the safety of the patient in the wheelchair. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides an assistive upper limb arm strength rehabilitation device and its usage method after encephalopathy surgery, which not only allows the user to easily support both ends of the rotating shaft, but also allows the device to be fixed together with the wheelchair during use, thereby improving the safety of wheelchair users.

[0005] This invention is achieved through the following technical solution: providing an assistive upper limb arm strength rehabilitation device after brain disease surgery, comprising a frame, two vertical rods provided on the top plate of the frame, the vertical rods passing through the top plate of the frame, the two vertical rods being distributed along the front-back extension direction of the frame, a first spring sleeved on the outer wall of the vertical rod, the lower end of the first spring being fixedly connected to the upper surface of the top plate of the frame, and the upper end of the first spring being fixedly connected to the vertical rod; a support column is provided on the left and right side walls of one of the vertical rods, the support column extending laterally along the left-right direction of the frame; a grip bar is connected to the lower end of the other vertical rod, two horizontal plates are sleeved on the outer wall of the other vertical rod, the two horizontal plates being distributed along the vertical direction, and connecting plates are also provided on the left and right sides of the other vertical rod, the connecting plates having a first rectangular elongated hole adapted to the support column, the first rectangular elongated hole extending laterally along the front-back direction of the frame; a first horizontal rod is provided between the two vertical rods, one end of the first horizontal rod is placed on the lower horizontal plate, the other end of the first horizontal rod is fixedly connected to the connecting plate, and the vertical distance between the two horizontal plates forms a rotation space for the first horizontal rod. The first crossbar is equipped with a rotating shaft extending laterally along the left-right direction of the frame. Two second crossbars are provided on the left and right sides of the handle. The two ends of the second crossbars are rotatably connected to the inner sidewalls of the front and rear columns of the frame, respectively. A rotating rod is provided on the second crossbar. A fixed rod is provided on the second crossbar near the handle on the side of the rotating rod. The fixed rod and the rotating rod are both perpendicular to the second crossbar. The included angle between the fixed rod and the rotating rod is 90°. A fixed through groove is provided on the side wall of the fixed rod away from the rotating rod. The length extension direction of the fixed through groove and the fixed rod are perpendicular. A semi-circular rubber ball is provided on the side plate of the fixed through groove. The lateral distance between the two semi-circular rubber balls forms a positioning channel for the handrail column. A connecting block is fixed to the end face of the rotating shaft. The upper and lower edges of the connecting block are arcs that are consistent with the rotation arc of the rotating rod and extend upward. A connecting hole adapted to the connecting block is provided on the rotating rod. Placement grooves adapted to the rotating rod are provided on the left and right end faces of the top plate of the frame, located within the vertical projection of the rotating shaft.

[0006] In use, this invention features two vertical rods on the top plate of the frame, passing through the top plate and extending along the front-rear direction of the frame. A first spring is fitted onto the outer wall of each vertical rod, with its lower end fixed to the upper surface of the top plate and its upper end fixed to the vertical rod. Support columns are mounted on the left and right side walls of one vertical rod, extending laterally along the left-right direction of the frame. A handle is attached to the lower end of the other vertical rod, and two horizontal plates are fitted onto its outer wall, distributed vertically. Connecting plates are also provided on the left and right sides of the other vertical rod, each with a first rectangular hole adapted to the support column, extending laterally along the front-rear direction of the frame. A first horizontal rod is positioned between the two vertical rods, with one end placed on... On the lower horizontal plate, the other end of the first horizontal plate is fixed to the connecting plate. The vertical distance between the two horizontal plates forms the rotation space of the first horizontal bar. A rotating shaft extending laterally along the left and right direction of the frame passes through the first horizontal bar. Two second horizontal bars are set on the left and right sides of the handle, and the two ends of the second horizontal bars are rotatably connected to the inner side walls of the front and rear columns of the frame, respectively. A rotating rod is set on the second horizontal bar. A fixed rod is set on the second horizontal bar on the side of the rotating rod closer to the handle. Both the fixed rod and the rotating rod are perpendicular to the second horizontal bar, and the included angle between the fixed rod and the rotating rod is 90°. A fixing through groove is opened on the side wall of the fixed rod away from the rotating rod, and the fixing through groove is perpendicular to the length extension direction of the fixed rod. A semi-circular rubber ball is set on the side plate of the fixing through groove, and the horizontal distance between the two semi-circular rubber balls is... A positioning channel for the armrest columns is formed by the distance between the columns. A connecting block is fixed to the end face of the rotating shaft. The upper and lower edges of the connecting block are arcs that coincide with the rotation arc of the rotating rod and extend upwards. A connecting hole adapted to the connecting block is opened on the rotating rod. Placement slots adapted to the rotating rod are opened on the left and right end faces of the top plate of the frame, located within the vertical projection of the rotating shaft. When using the device, the user needs to drive the wheelchair into the frame through the gap between the two columns on the rear side of the frame, grasp the fixed rod and rotate it towards the inside of the frame until it is horizontal with the ground. This causes the second crossbar to rotate with the fixed rod, and drives the rotating rod on the second crossbar to screw into the placement slot and connect with the bottom of the placement slot. During the rotation of the rotating rod, the connecting block on the end face of the rotating shaft is inserted into the connecting hole of the rotating rod. This supports both ends of the rotating shaft, and then moves the wheelchair forward. This causes the armrest posts on both sides of the wheelchair to press against the semi-circular rubber balls in the fixing groove. The armrest posts then pass through the positioning channel formed by the lateral distance between the two semi-circular rubber balls and enter the fixing groove, connecting with the bottom of the groove. This secures the wheelchair armrest posts to the fixing rod. Next, the user grips the handle and pulls downwards, causing the vertical rod located at the rear of the frame to move downwards and compress the first spring fitted on the rear vertical rod. This causes the horizontal plate to move downwards. When the upper horizontal plate contacts the first horizontal rod, it drives the rear end of the first horizontal rod to rotate downwards around the rotating shaft, causing the front end of the first horizontal rod to rotate upwards and drive the connecting plate to rotate.At this time, driven by the connecting plate and the first rectangular hole, the support column also moves upward, driving the vertical rod located on the front side of the frame to move upward, stretching the spring sleeved on the vertical rod on the front side of the frame. Then, the handle is moved back to the initial position, causing the vertical rod to return to the initial position under the drive of the spring. This reciprocating motion exercises the user's upper limbs. This not only facilitates the user's support of both ends of the rotating shaft, but also allows the device to be fixed to the wheelchair during use, improving the safety of wheelchair users.

[0007] Preferably, three rotating shafts are provided on the first crossbar, and the three rotating shafts are equidistantly distributed along the length extension direction of the first crossbar. A connecting rod extending laterally along the length direction of the second crossbar is provided on the outer side wall of the second crossbar. The front and rear ends of the connecting rod are respectively flush with the inner side walls of the front and rear columns of the frame. A round tube is also sleeved on the second crossbar. The inner side wall of the round tube is adapted to the outer edge of the second crossbar and the connecting rod. The rotating rod is fixed to the second crossbar through the round tube. A plurality of fixing holes adapted to the fixing rod are opened on the outer side wall of the round tube. The plurality of fixing holes are equidistantly distributed along the length extension direction of the round tube. The fixing rod is inserted into one of the fixing holes and detachably fixed to the round tube. By setting three rotating shafts on the first crossbar, the three rotating shafts are equidistantly distributed along the length of the first crossbar. A connecting rod is set on the outer wall of the second crossbar along the length of the second crossbar, and the front and rear ends of the connecting rod are flush with the inner side walls of the front and rear columns of the frame. A round tube is sleeved on the second crossbar, and the inner side wall of the round tube is adapted to the outer edge of the second crossbar and the connecting rod. The rotating rod is fixed to the second crossbar through the round tube. Several fixing holes adapted to the fixing rod are opened on the outer wall of the round tube. The fixing holes are equidistantly distributed along the length of the round tube. The fixing rod is inserted into one of the fixing holes and detachably fixed to the round tube. Pushing the fixing rod causes the round tube to move back and forth on the second crossbar, which can adjust the position of the rotating rod on the second crossbar. This allows the rotating rod to be screwed into different placement slots when rotating, and the rotating shafts at different positions on the first crossbar can be fixed together with the rotating rod. This makes it convenient for wheelchair users to adjust the exercise intensity of the device.

[0008] Preferably, two upright plates are fixed to the lower end face of the frame column, and the two upright plates are distributed along the left-right extension direction of the frame. A traveling wheel, hinged to the two upright plates, is provided between the two upright plates. The lower end face of each upright plate is higher than the lower end face of the traveling wheel. A second rectangular elongated hole extending vertically is provided on the rear upright of the frame. The second rectangular elongated hole extends horizontally through the left-right direction of the frame. Two circular blocks are provided within the second rectangular elongated hole, and the two circular blocks are aligned and pressed together vertically. A movable rod is fixed to the lower end face of the lower circular block. The movable rod extends vertically... The movable rod extends downwards through the frame and between the two uprights. A pressure plate is attached to the lower end of the movable rod, and the lower end of the pressure plate presses against the upper end of the traveling wheel. A second spring is also fitted on the movable rod located in the second rectangular hole. The upper end of the second spring is fixed to the lower circular block, and the lower end of the second spring is fixed to the frame. The second crossbar extends laterally along the front-back direction of the frame into the second rectangular hole and is fixed to the upper circular block. The connection point between the axis of the second crossbar and the upper circular block is located directly above the axis of the upper circular block. The rotating rod extends laterally toward the direction of the second crossbar. Two vertical plates are fixed to the lower end face of the frame column, and the two vertical plates are distributed along the left and right extension direction of the frame. A traveling wheel is hinged between the two vertical plates. The lower end face of the vertical plate is higher than the lower end face of the traveling wheel. A second rectangular hole extending vertically is opened on the rear column of the frame, and the second rectangular hole extends laterally through the left and right direction of the frame. Two circular blocks are placed inside the second rectangular hole, aligned vertically and pressed together. A movable rod is fixed to the lower end face of the lower circular block, extending vertically downward through the frame and between the two vertical plates. A pressure plate is attached to the lower end of the movable rod, and the lower end face of the pressure plate presses against the upper end face of the traveling wheel. A second spring is fitted on the movable rod located in the second rectangular hole. The upper end of the first spring is fixed to the lower circular block, and the lower end of the second spring is fixed to the frame. A second crossbar extends laterally along the front and rear direction of the frame to the second rectangular hole and connects with the upper circular block. The connection point between the second crossbar axis and the upper circular block is located directly above the axis of the upper circular block. The rotating rod extends laterally towards the second crossbar. As the fixed rod rotates towards the inside of the frame and parallel to the ground, the rotating rod on the circular tube will be screwed into the placement slot. The circular tube will drive the second crossbar to rotate through the transmission of the connecting rod, causing the second crossbar to drive the circular block connected to it to rotate. This causes the end of the upper circular block away from the second crossbar to change from vertical to horizontal, no longer touching the lower circular block. This increases the distance between the end of the lower circular block away from the movable rod and the end of the upper circular block near the movable rod. The lower circular block loses downward pressure and moves upward under the push of the second spring, touching the upper circular block again. This causes the lower circular block to drive the movable rod upward, causing the pressure plate at the lower end of the movable rod to disengage from the traveling wheel, thus facilitating the user to move the device according to actual needs.

[0009] Preferably, the circular block, the movable rod, and the pressure plate are aligned vertically. Aligning the circular block, the movable rod, and the pressure plate vertically facilitates the vertical movement of the movable rod within the frame.

[0010] Preferably, a support plate is fixedly connected to the upper end of the vertical rod, and the upper end of the first spring is fixedly connected to the vertical rod via the support plate. By fixing the support plate to the upper end of the vertical rod and the upper end of the first spring to the vertical rod via the support plate, the connection stability between the vertical rod and the first spring can be improved, preventing the first spring from falling off during use.

[0011] Preferably, a positioning rod is provided on the side of the second crossbar away from the grip, which is fixed to the inner wall of the front and rear columns of the frame, and the rotating rod presses against the upper end face of the positioning rod. By providing a positioning rod fixed to the inner wall of the front and rear columns of the frame on the side of the second crossbar away from the grip, and by having the rotating rod press against the upper end face of the positioning rod, the positioning rod can support the rotating rod when it is not rotating, thus preventing the second crossbar and the circular block connected to it from shaking accidentally during use.

[0012] Preferably, a positioning plate is fixedly connected to the end of the rotating rod away from the circular tube, and the vertical distance from the positioning plate to the circular tube is the same as the vertical distance from the circular tube to the top plate of the frame. By fixing the positioning plate to the end of the rotating rod away from the circular tube, and ensuring that the vertical distance from the positioning plate to the circular tube is the same as the vertical distance from the circular tube to the top plate of the frame, the positioning plate can be pressed against the top plate of the frame when the rotating rod is screwed into the placement groove and contacts the bottom of the groove, thereby providing positioning support for the rotating rod.

[0013] A method for using an assistive upper limb arm strength rehabilitation device after brain disease surgery includes the following steps:

[0014] a. The wheelchair user pushes the wheelchair into the frame through the gap between the two uprights at the rear of the frame, then holds the fixed rod and pushes the round tube to move back and forth on the second crossbar. Adjust the position of the rotating rod on the round tube on the positioning rod, then rotate the fixed rod toward the inside of the frame until it is parallel to the ground, causing the round tube to rotate. The second crossbar rotates under the transmission of the connecting rod, and the rotating rod on the round tube is screwed into one of the placement slots on the top plate of the frame. The rotating rod is connected to the bottom of the placement slot, and the connecting block on the end face of the rotating shaft on the first crossbar corresponding to the placement slot is inserted into the connecting hole of the rotating rod. The positioning plate at the end of the rotating rod away from the round tube is pressed against the top plate of the frame.

[0015] b. During the rotation of the second crossbar, the upper circular block inside the second rectangular long hole will rotate. The upper circular block away from the second crossbar will change from vertical to horizontal and will no longer be in contact with the lower circular block. This will increase the distance between the lower circular block away from the movable rod and the upper circular block near the movable rod. The lower circular block will lose its downward pressure and move upward under the drive of the second spring, and then be in contact with the upper circular block again. The movable rod will move upward under the drive of the second spring, causing the pressure plate to disengage from the upper surface of its corresponding traveling wheel.

[0016] c. Pull the fixing rod backward to move the frame backward under the transmission of the round tube, rotating rod and placement slot. This allows the armrest columns on both sides of the wheelchair to enter the fixing slot through the positioning channel formed by the two semi-circular rubber balls, fixing the armrest columns on both sides of the wheelchair to the two fixing rods on the left and right sides of the frame. Then pull the grip bar downward to move the support plate and horizontal plate on the rear vertical rod of the frame downward, compressing the first spring on the rear side of the frame. This allows the upper horizontal plate to press the rear end of the first horizontal rod to rotate downward around the rotation axis, driving the front end of the first horizontal rod to rotate upward. This causes the connecting plate to rotate upward with the first horizontal rod, and the support column in the first rectangular long hole to move upward with the rotation of the connecting plate. This causes the vertical rod on the front side of the frame to move upward, stretching the first spring on the front side of the frame. Then move the grip bar back to the initial position, so that the vertical rod, horizontal plate and support plate also return to the initial position under the drive of the first spring, thus exercising the user's upper limbs.

[0017] d. After the user finishes exercising, the fixed rod is rotated back to the initial position, which drives the connecting rod, the round tube, the second crossbar and the rotating rod to rotate. The rotating rod is rotated out of one of the placement slots and pressed back onto the positioning rod. The support plate is no longer pressed onto the top plate of the frame. The upper circular block in the second rectangular hole returns to the initial position under the drive of the second crossbar and compresses the second spring. The movable rod moves downward under the drive of the circular block and the pressure plate at the lower end of the movable rod presses back onto the walking wheel.

[0018] e. When the user needs to adjust the exercise intensity, push the fixed rod to move the round tube on the second crossbar, then rotate the fixed rod around the second crossbar toward the inside of the frame so that the fixed rod is horizontal with the ground, and drive the rotating rod on the round tube to be screwed into another placement slot on the top plate of the frame, and insert the connecting block at the end of the corresponding rotating shaft into the connecting hole of the rotating rod, so that the positioning plate at the end of the rotating rod away from the round tube is pressed back onto the top plate of the frame.

[0019] f. When the fixing rod is far from the grip bar, it is inconvenient for the user to grasp the grip bar after the wheelchair is secured. Pull the fixing rod out of the original fixing hole on the round tube and then insert the fixing rod into another fixing hole closer to the grip bar.

[0020] The beneficial effects of this invention are as follows: Two vertical rods are provided on the top plate of the frame, passing through the top plate and distributed along the front-to-back extension direction of the frame. A first spring is sleeved on the outer wall of the vertical rod, with its lower end fixed to the upper surface of the top plate and its upper end fixed to the vertical rod. Support columns are provided on the left and right side walls of one vertical rod, extending laterally along the left-to-right direction of the frame. A handle is attached to the lower end of the other vertical rod, and two horizontal plates are sleeved on its outer wall, distributed vertically. Connecting plates are also provided on the left and right sides of the other vertical rod, with a first rectangular hole adapted to the support column, extending laterally along the front-to-back direction of the frame. A first horizontal rod is provided between the two vertical rods, with one end of the first horizontal rod placed on... On the lower horizontal plate, the other end of the first horizontal plate is fixed to the connecting plate. The vertical distance between the two horizontal plates forms the rotation space of the first horizontal bar. A rotating shaft extending laterally along the left and right direction of the frame passes through the first horizontal bar. Two second horizontal bars are set on the left and right sides of the handle, and the two ends of the second horizontal bars are rotatably connected to the inner side walls of the front and rear columns of the frame, respectively. A rotating rod is set on the second horizontal bar. A fixed rod is set on the second horizontal bar on the side of the rotating rod closer to the handle. Both the fixed rod and the rotating rod are perpendicular to the second horizontal bar, and the included angle between the fixed rod and the rotating rod is 90°. A fixing through groove is opened on the side wall of the fixed rod away from the rotating rod, and the fixing through groove is perpendicular to the length extension direction of the fixed rod. A semi-circular rubber ball is set on the side plate of the fixing through groove, and the horizontal distance between the two semi-circular rubber balls is... A positioning channel for the armrest columns is formed by the distance between the columns. A connecting block is fixed to the end face of the rotating shaft. The upper and lower edges of the connecting block are arcs that coincide with the rotation arc of the rotating rod and extend upwards. A connecting hole adapted to the connecting block is opened on the rotating rod. Placement slots adapted to the rotating rod are opened on the left and right end faces of the top plate of the frame, located within the vertical projection of the rotating shaft. When using the device, the user needs to drive the wheelchair into the frame through the gap between the two columns on the rear side of the frame, grasp the fixed rod and rotate it towards the inside of the frame until it is horizontal with the ground. This causes the second crossbar to rotate with the fixed rod, and drives the rotating rod on the second crossbar to screw into the placement slot and connect with the bottom of the placement slot. During the rotation of the rotating rod, the connecting block on the end face of the rotating shaft is inserted into the connecting hole of the rotating rod. This supports both ends of the rotating shaft, and then moves the wheelchair forward. This causes the armrest posts on both sides of the wheelchair to press against the semi-circular rubber balls in the fixing groove. The armrest posts then pass through the positioning channel formed by the lateral distance between the two semi-circular rubber balls and enter the fixing groove, connecting with the bottom of the groove. This secures the wheelchair armrest posts to the fixing rod. Next, the user grips the handle and pulls downwards, causing the vertical rod located at the rear of the frame to move downwards and compress the first spring fitted on the rear vertical rod. This causes the horizontal plate to move downwards. When the upper horizontal plate contacts the first horizontal rod, it drives the rear end of the first horizontal rod to rotate downwards around the rotating shaft, causing the front end of the first horizontal rod to rotate upwards and drive the connecting plate to rotate.At this time, driven by the connecting plate and the first rectangular hole, the support column also moves upward, driving the vertical rod located on the front side of the frame to move upward, stretching the spring sleeved on the vertical rod on the front side of the frame. Then, the handle is moved back to the initial position, causing the vertical rod to return to the initial position under the drive of the spring. This reciprocating motion exercises the user's upper limbs. This not only facilitates the user's support of both ends of the rotating shaft, but also allows the device to be fixed to the wheelchair during use, improving the safety of wheelchair users.

[0031] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0032] like Figures 1-8 The present invention discloses an auxiliary upper limb arm strength rehabilitation device for post-encephalopathic brain disease surgery, comprising a frame 2. Two vertical rods 1 are disposed on the top plate of the frame 2, passing through the top plate. The two vertical rods 1 are distributed along the front-back extension direction of the frame 2. A first spring 13 is sleeved on the outer wall of each vertical rod 1, with its lower end fixed to the upper surface of the top plate of the frame 2 and its upper end fixed to the vertical rod 1. Support columns 14 are disposed on the left and right side walls of one vertical rod 1, extending laterally along the left-right direction of the frame 2. A grip bar 4 is attached to the lower end of the other vertical rod 1. Two horizontal plates 3 are fitted onto the outer wall of the vertical rod 1, and the two horizontal plates 3 are distributed vertically. Connecting plates 15 are also provided on the left and right sides of the other vertical rod 1. The connecting plates 15 have first rectangular elongated holes 16 adapted to the support column 14, and the first rectangular elongated holes 16 extend laterally along the front-rear direction of the frame 2. A first horizontal rod 17 is provided between the two vertical rods 1. One end of the first horizontal rod 17 is placed on the lower horizontal plate 3, and the other end of the first horizontal rod 17 is fixedly connected to the connecting plate 15. The vertical distance between the two horizontal plates 3 forms a rotation space for the first horizontal rod 17. A rotating shaft 7 extending laterally along the left-right direction of the frame 2 is provided. Two second crossbars 18 are provided on the left and right sides of the grip 4. The two ends of the second crossbars 18 are rotatably connected to the inner sidewalls of the front and rear columns of the frame 2, respectively. A rotating rod 30 is provided on the second crossbar 18. A fixed rod 8 is provided on the second crossbar 18 on the side of the second crossbar 18 closest to the grip 4, and both the fixed rod 8 and the rotating rod 30 are perpendicular to the second crossbar 18. The included angle between the fixed rod 8 and the rotating rod 30 is 90°. A fixing through groove 27 is provided on the sidewall of the fixed rod 8 away from the rotating rod 30. The length extension directions of the fixed through groove 27 and the fixed rod 8 are perpendicular. A semi-circular rubber ball 28 is provided on the side plate of the fixed through groove 27. The lateral distance between the two semi-circular rubber balls 28 forms a positioning channel for the handrail column. A connecting block 6 is fixedly connected to the end face of the rotating shaft 7. The upper and lower edges of the connecting block 6 are arcs that are consistent with the rotation arc of the rotating rod 30 and extend upward. A connecting hole 32 adapted to the connecting block 6 is opened on the rotating rod 30. Placement grooves 5 located within the vertical projection of the rotating shaft 7 and adapted to the rotating rod 30 are opened on the left and right end faces of the top plate of the frame 2.

[0033] Three rotating shafts 7 are arranged on the first crossbar 17, and the three rotating shafts 7 are equidistantly distributed along the length of the first crossbar 17. A connecting rod 19 extending along the length of the second crossbar 18 is arranged on the outer wall of the second crossbar 18, and the front and rear ends of the connecting rod 19 are flush with the inner side walls of the front and rear columns of the frame 2. A round tube 9 is sleeved on the second crossbar 18, and the inner side wall of the round tube 9 is adapted to the outer edge of the second crossbar 18 and the connecting rod 19. The rotating rod 30 is fixed to the second crossbar 18 through the round tube 9. The outer side wall of the round tube 9 is provided with a part adapted to the fixed rod 8. A number of fixing holes 29 are equidistantly distributed along the length of the circular tube 9. A fixing rod 8 is inserted into one of the fixing holes 29 and detachably fixed to the circular tube 9. Pushing the fixing rod 8 causes the circular tube 9 to move back and forth on the second crossbar 18, which can adjust the position of the rotating rod 30 on the second crossbar 18. This allows the rotating rod 30 to be screwed into different placement slots 5 when rotating, and the rotating shafts 7 at different positions on the first crossbar 17 can be fixed together with the rotating rod 30. This makes it convenient for wheelchair users to adjust the exercise intensity of the device.Two upright plates 26 are fixed to the lower end face of the upright column of the frame 2. The two upright plates 26 are distributed along the left and right extension direction of the frame 2. A traveling wheel 20 is provided between the two upright plates 26 and is hinged to the two upright plates 26. The lower end face of the upright plate 26 is higher than the lower end face of the traveling wheel 20. A second rectangular elongated hole 24 extending vertically is opened on the rear upright of the frame 2. The second rectangular elongated hole 24 is transversely connected along the left and right direction of the frame 2. Two circular blocks 21 are provided in the second rectangular elongated hole 24. The two circular blocks 21 are aligned and pressed together vertically. A movable rod 23 is fixedly connected to the lower end face of the lower circular block 21. The movable rod 23 extends vertically downward through the frame 2 and extends to the space between the two upright plates 26. A pressure plate 31 is connected to the lower end of the movable rod 23, and the lower end face of the pressure plate 31 presses against the upper end face of the traveling wheel 20. A second spring 25 is sleeved on the movable rod 23 located in the second rectangular elongated hole 24. The upper end of the first spring 13 is fixedly connected to the lower circular block 21, and the lower end of the second spring 25 is fixedly connected to the frame 2. The second crossbar 18 extends laterally along the front-back direction of the frame 2 into the second rectangular elongated hole 24 and is connected to the upper... The side circular block 21 is fixedly connected. The connection point between the axis of the second crossbar 18 and the upper side circular block 21 is located directly above the axis of the upper side circular block 21. The rotating rod 30 extends laterally towards the second crossbar 18. As the fixed rod 8 rotates towards the inside of the frame 2 and parallel to the ground, the rotating rod 30 on the circular tube 9 will be screwed into the placement groove 5. The circular tube 9 will drive the second crossbar 18 to rotate through the transmission of the connecting rod 19, causing the second crossbar 18 to drive the circular block 21 connected to it to rotate, and causing the end of the upper side circular block 21 away from the second crossbar 18 to face... The vertical rod 21 changes to a horizontal position, no longer pressing against the lower circular block 21. This increases the distance between the lower circular block 21 away from the movable rod 23 and the upper circular block 21 near the movable rod 23. The lower circular block 21 loses its downward pressure and moves upward under the push of the second spring 25, pressing against the upper circular block 21 again. This causes the lower circular block 21 to move the movable rod 23 upward, disengaging the pressure plate 31 at the lower end of the movable rod 23 from the traveling wheel 20. This facilitates the user's movement of the device according to actual needs. By aligning the circular block 21, movable rod 23, and pressure plate 31 vertically, the movable rod 23 can move up and down within the frame 2. A support plate 12 is fixed to the upper end of the vertical rod 1, and the upper end of the first spring 13 is fixed to the vertical rod 1 via the support plate 12. The support plate 12 improves the connection stability between the vertical rod 1 and the first spring 13, preventing the first spring 13 from falling off during use. By providing a positioning rod 11 on the side of the second crossbar 18 away from the grip 4, which is fixed to the inner side wall of the front and rear columns of the frame 2, and the rotating rod 30 pressing against the upper end face of the positioning rod 11, the positioning rod 11 can support the rotating rod 30 when it is not rotating, thus preventing the second crossbar 18 and the circular block 21 connected to it from shaking accidentally during use.By fixing a positioning plate 10 to the end of the rotating rod 30 away from the round tube 9, and the vertical distance from the positioning plate 10 to the round tube 9 is the same as the vertical distance from the round tube 9 to the top plate of the frame 2, the positioning plate 10 can be pressed against the top plate of the frame 2 when the rotating rod 30 is screwed into the placement groove 5 and connected to the bottom of the placement groove 5, thereby supporting the rotating rod 30.

[0034] A method for using an assistive upper limb arm strength rehabilitation device after brain disease surgery includes the following steps:

[0035] a. The wheelchair user pushes the wheelchair into the frame 2 through the gap between the two columns on the rear side of the frame 2, then holds the fixing rod 8 and pushes the round tube 9 to move back and forth on the second crossbar 18. Adjust the position of the rotating rod 30 on the round tube 9 on the positioning rod 11, then make the fixing rod 8 rotate towards the inside of the frame 2 and parallel to the ground, driving the round tube 9 to rotate. This causes the second crossbar 18 to rotate under the transmission of the connecting rod 19, and the rotating rod 30 on the round tube 9 to be screwed into one of the placement slots 5 on the top plate of the frame 2. The rotating rod 30 is connected to the bottom of the placement slot 5, and the connecting block 6 on the end face of the rotating shaft 7 on the first crossbar 17 corresponding to the placement slot 5 is inserted into the connecting hole 32 of the rotating rod 30. The positioning plate 10 at the end of the rotating rod 30 away from the round tube 9 is pressed against the top plate of the frame 2.

[0036] b. During the rotation of the second crossbar 18, the upper circular block 21 inside the second rectangular long hole 24 will rotate. The upper circular block 21 away from the second crossbar 18 will change from vertical to horizontal and will no longer be in contact with the lower circular block 21. This will increase the distance between the lower circular block 21 away from the movable rod 23 and the upper circular block 21 close to the movable rod 23. The lower circular block 21 will lose its downward pressure and move upward under the drive of the second spring 25, and then be in contact with the upper circular block 21 again. The movable rod 23 will move upward under the drive of the second spring 25, causing the pressure plate 31 to disengage from the upper surface of its corresponding traveling wheel 20.

[0037] c. Pull the fixing rod 8 backward, causing the frame 2 to move backward under the transmission of the round tube 9, rotating rod 30, and placement groove 5. This allows the armrest columns on both sides of the wheelchair to enter the fixing groove 27 through the armrest column positioning channel formed by the two semi-circular rubber balls 28, thus fixing the armrest columns on both sides of the wheelchair to the two fixing rods 8 on the left and right sides of the frame 2. Then, pull the grip rod 4 downward, causing the support plate 12 and horizontal plate 3 on the rear vertical rod 1 of the frame 2 to move downward, compressing the first spring 13 on the rear side of the frame 2, and enabling the upper horizontal plate 3 to press the first spring 13. The rear end of a horizontal bar 17 rotates downward around the rotating shaft 7, driving the front end of the first horizontal bar 17 to rotate upward, causing the connecting plate 15 to rotate upward with the first horizontal bar 17, and causing the support column 14 in the first rectangular long hole 16 to move upward with the rotation of the connecting plate 15, driving the vertical bar 1 on the front side of the frame 2 to move upward, stretching the first spring 13 on the front side of the frame 2, and then moving the grip bar 4 back to the initial position, so that the vertical bar 1, the horizontal plate 3 and the support plate 12 also return to the initial position under the drive of the first spring 13, thus exercising the user's upper limbs;

[0038] d. After the user finishes exercising, the fixed rod 8 is rotated back to the initial position, which drives the connecting rod 19, the round tube 9, the second crossbar 18 and the rotating rod 30 to rotate, so that the rotating rod 30 is rotated out from one of the placement slots 5 and pressed back onto the positioning rod 11. The support plate 12 is no longer pressed on the top plate of the frame 2, so that the upper circular block 21 in the second rectangular long hole 24 returns to the initial position under the drive of the second crossbar 18 and compresses the second spring 25, so that the movable rod 23 moves downward under the drive of the circular block 21, and the pressure plate 31 at the lower end of the movable rod 23 is pressed back onto the walking wheel 20.

[0039] e. When the user needs to adjust the exercise intensity, push the fixed rod 8 to move the round tube 9 on the second cross bar 18, then rotate the fixed rod 8 around the second cross bar 18 toward the inside of the frame 2, so that the fixed rod 8 is horizontal with the ground, and drive the rotating rod 30 on the round tube 9 to be screwed into another placement slot 5 on the top plate of the frame 2, and insert the connecting block 6 at the end of the corresponding rotating shaft 7 into the connecting hole 32 of the rotating rod 30, so that the positioning plate 10 at the end of the rotating rod 30 away from the round tube 9 is pressed back onto the top plate of the frame 2.

[0040] f. When the fixing rod 8 is far from the grip bar 4, it is inconvenient for the user to grasp the grip bar 4 after the wheelchair is fixed. Pull the fixing rod 8 out of the original fixing hole 29 on the round tube 9, and then insert the fixing rod 8 into another fixing hole 29 close to the grip bar 4.
