At this time, a mounting frame 40 is set at one end of the top of the limit box 35, and the spring rod 41 set at the top of the inner wall of the mounting frame 40 is used to push the wedge block 36 to move downward, and the connecting end of the tilting tube 37 and the plug block 38 is tilted, so that the plug block 38 (the plug block 38 has a rebound reset property) is inserted from the notch set at the bottom of the slot 24.One side of the outer wall of the insert block 38 is in contact with the ramp plate provided at the bottom of one side of the inner wall of the special-shaped block 25, so that the insert block 38 is used to reset the special-shaped block 25 and fix it (here the elastic force of the spring rod 41 is greater than the annular spring 30), so that the special-shaped block 25 drives the fixing rod 26 to reset the clamping plate 27, so that the patient's arms are separated from the placement table 11, further solving the problem that the traditional limb rehabilitation training power-assisting device often needs medical staff to help the patient fix the limbs on the power-assisting device during use, which leads to greater limitations in the use of the power-assisting device.

[0034] A connecting plate 42 is fixedly connected to one side of the outer wall of the moving block 6, a reset shaft 43 is fixedly connected to the bottom of the connecting plate 42, an electric clamping plate 44 is fixedly connected to one end of the outer wall of the reset shaft 43, a slider 45 is rotatably connected to the output end of the electric clamping plate 44, and a friction surface on one side of the outer wall of the slider 45 clamps the end of the outer wall of the stabilizing block 9 away from the first electric telescopic rod 10.

[0035] During operation, a connecting plate 42 is provided on one side of the outer wall of the moving block 6, and a reset shaft 43 is provided at the bottom of the connecting plate 42. When the transmission shaft 8 drives the placement table 11 to swing up and down, an electric clamping plate 44 is provided at one end of the outer wall of the reset shaft 43, and a slider 45 is provided at the output end of the electric clamping plate 44. The slider 45 is used to clamp the end of the stabilizing block 9 away from the first electric telescopic rod 10 (without affecting the normal operation of the placement table 11), so that the placement table 11 is more stable when moving up and down, and the problem of the patient suddenly exerting force during assisted training, which causes the trajectory of the placement table 11 to change, is avoided.

[0036] A guide box 46 is fixedly connected to one end of the bottom of the inner wall of the moving block 6 away from the rotating shaft 7, and baffles are fixedly connected to the two ends of the top of the guide box 46. The inner wall of the guide box 46 is slidably connected to a limiting wheel 47, and the center of the limiting wheel 47 is fixedly connected to the outer wall of the transmission shaft 8.

[0037] During operation, a guide box 46 is set at one end of the bottom of the inner wall of the moving block 6 away from the rotating shaft 7, and baffles are set at both ends of the top of the guide box 46. When the patient needs to swing his shoulders left and right, the motor 13 drives the second bevel gear 15 set at one end of the transmission shaft 8 to rotate through the first bevel gear 14, so that the transmission shaft 8 rotates with the rotating shaft 7 as the center. By setting a limiting wheel 47 in the middle of the outer wall of the transmission shaft 8, when the transmission shaft 8 rotates with the rotating shaft 7 as the center, the limiting wheel 47 moves in the guide box 46. When the transmission shaft 8 moves to the maximum offset angle, the outer wall of the limiting wheel 47 contacts the baffle, thereby limiting the transmission shaft 8 to avoid excessive offset angles and causing strain to the patient's shoulder muscles.

[0038] A power-assisted rehabilitation method for limb rehabilitation training, the method adopts the above-mentioned power-assisted device for limb rehabilitation training, and the method is as follows: S1: A limit plate 4 is provided at one end of the top of the power-assisting body 1, a slide groove 5 is provided at the top of one side of the outer wall of the limit plate 4, and the moving blocks 6 provided at both sides of the inner wall of the slide groove 5 are pushed, so that the moving blocks 6 drive the placing table 11 provided at one end of the stabilizing block 9 to move to a position suitable for the patient's shoulder width; S2: By setting a rotating shaft 7 at one end of the bottom of the inner wall of the moving block 6, setting a transmission shaft 8 at the top of the rotating shaft 7, and setting a motor 13 at one end of the top of the inner wall of the moving block 6, so that it drives the first bevel gear 14 set at the output end, so that the first bevel gear 14 drives the transmission shaft 8 away from the second bevel gear 15 set at one end of the stabilizing block 9, so that the transmission shaft 8 drives the placement table 11 through the stabilizing block 9, so as to help the patient to perform rehabilitation training; S3: By hanging the arms in the arc-shaped support plate 32 arranged on the inner wall of the placement table 11, using the weight of the patient's arms, the linkage plate 33 pushes the wedge block 36, so that the tilting tube 37 drives the insert block 38 to move downward, breaking away from the restriction of the special-shaped block 25, so that the annular spring 30 in the annular box 29 pushes the clamping plate 27 to clamp and fix the patient's arms.

[0039] The working principle of the power-assisting device and rehabilitation method for limb rehabilitation training will be specifically described below.

[0040] like Figure 1-10As shown, by setting a limit plate 4 at one end of the top of the power-assisting body 1, setting a slide groove 5 at the top of one side of the outer wall of the limit plate 4, and pushing the moving blocks 6 set on both sides of the inner wall of the slide groove 5, the moving blocks 6 drive the placement table 11 set at one end of the stabilizing block 9 to move to a position suitable for the patient's shoulder width, and by setting a first electric telescopic rod 10 between the stabilizing block 9 and the placement table 11, the first electric telescopic rod 10 is started to adjust the placement table 11 to the patient's arm length, thereby solving the problem of the limitation of the use of the power-assisting body 1 when facing patients with different body shapes, and by setting a seat 2 at the top of the power-assisting body 1, the patient is allowed to sit on the seat 2, so that the patient's back fits the backrest of the seat 2, and the down-pressing device 3 set in the middle of one side of the outer wall of the seat 2 is embedded in the backrest, Thereby activating the electric winch 18, it is convenient to fix the patient's arms later. At this time, the patient's arms are placed flat on the placement table 11 with the palms facing inward, and the patient's arms are fixed by using the clamping plate 27 provided in the linkage bin 12. A rotating shaft 7 is provided at one end of the bottom of the inner wall of the moving block 6, and a transmission shaft 8 is provided at the top of the rotating shaft 7. The stabilizing block 9 is adjusted by using the transmission shaft 8. When the patient needs to swing his shoulders up and down, a motor 13 is provided at one end of the top of the inner wall of the moving block 6 to drive the first bevel gear 14 provided at the output end, so that the first bevel gear 14 drives the transmission shaft 8 away from the second bevel gear 15 provided at one end of the stabilizing block 9, so that the transmission shaft 8 drives the placement table 11 through the stabilizing block 9, and the patient's arms are pushed with the transmission shaft 8 as the center. The arm swings up and down, a connecting plate 42 is arranged on one side of the outer wall of the moving block 6, and a reset shaft 43 is arranged at the bottom of the connecting plate 42. When the transmission shaft 8 drives the placement table 11 to swing up and down, an electric clamping plate 44 is arranged at one end of the outer wall of the reset shaft 43, and a slider 45 is arranged at the output end of the electric clamping plate 44. The slider 45 is used to clamp the end of the stabilizing block 9 away from the first electric telescopic rod 10 (without affecting the normal operation of the placement table 11), so that the placement table 11 is more stable when moving up and down, and the patient is prevented from suddenly exerting force during assisted training, which causes the trajectory of the placement table 11 to change. When the patient needs to swing his shoulders left and right, a second electric telescopic rod 16 is arranged at the end of the top of the inner wall of the moving block 6 away from the motor 13 to start The second electric telescopic rod 16 is moved to release the clamping block 17 set at its output end from the restriction on the transmission shaft 8. At this time, when the motor 13 drives the second bevel gear 15 set at one end of the transmission shaft 8 to rotate through the first bevel gear 14, the transmission shaft 8 is rotated with the rotating shaft 7 as the center, and the transmission shaft 8 drives the placement table 11 to make the patient's arms deviate inward or outward. By setting a guide box 46 at the end away from the rotating shaft 7 at the bottom of the inner wall of the moving block 6, and setting baffles at both ends of the top of the guide box 46, when the patient needs to swing his shoulders left and right, the motor 13 drives the second bevel gear 15 set at one end of the transmission shaft 8 to rotate through the first bevel gear 14, so that the transmission shaft 8 is rotated with the rotating shaft 7 as the center, and a limiting wheel 47 is set in the middle of the outer wall of the transmission shaft 8.When the transmission shaft 8 rotates with the rotating shaft 7 as the center, the limiting wheel 47 moves in the guide box 46. When the transmission shaft 8 moves to the maximum offset angle, the outer wall of the limiting wheel 47 contacts the baffle, thereby limiting the transmission shaft 8 to avoid excessive offset angles and straining the patient's shoulder muscles. This further solves the problem that it is difficult to perform rehabilitation training on the patient's shoulder joint during the use of traditional limb rehabilitation training assisting devices. It should be noted that, although the above embodiments have been described in this article, the patent protection scope of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, changes and modifications made to the embodiments described herein, or equivalent structures or equivalent process changes made using the contents of the present invention specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present invention.
