[0029] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.
[0030] This application discloses a multifunctional rehabilitation chair for neurological rehabilitation. (Refer to...) Figure 2 - Figure 4A multifunctional rehabilitation chair for neurological rehabilitation includes a main body 10. Vertical rods 21 are symmetrically fixedly mounted on the bottom of the main body 10. Connecting blocks 22 are fixedly mounted on each vertical rod 21. Fixing blocks 23 are symmetrically fixedly mounted on one end of each connecting block 22. Rotating rods 30 are movably mounted on each of the two fixing blocks 23. First sprockets 31 are fixedly mounted on each rotating rod 30, located below the connecting blocks 22. Vertical blocks 32 are fixedly mounted on the bottom of each connecting block 22. Horizontal blocks 33 are fixedly mounted on the bottom of each vertical block 32. Movable rods 41 are movably mounted on each vertical block 32. Second sprockets 42 are fixedly mounted on each movable rod 41. Chains 43 are wound around the second sprockets 42 and the first sprockets 31 respectively. One end of each movable rod 41 is fixedly mounted on... A first equal-diameter bevel gear 50 is fixedly mounted on a fixed block 23. An operating motor 40 is fixedly mounted on one of the vertical blocks 32, and the output end of the operating motor 40 is fixedly mounted to the movable rod 41. A traction rod 51 is movably mounted on each of the horizontal blocks 33. A second equal-diameter bevel gear 52, corresponding to the tooth pattern of the first equal-diameter bevel gear 50, is fixedly mounted on the top of each traction rod 51. A traction gear 53 is fixedly mounted on the bottom of each traction rod 51, and the two traction gears 53 are tooth patterned together. Adjusting blocks 73 are symmetrically fixedly mounted on each of the rotating rods 30, located on both sides of the fixed block 23. A support block 12 is fixedly mounted on one end of each of the two adjusting blocks 73. A traction groove 60 is provided on the back of each support block 12, and a guide rod 61 is symmetrically fixedly mounted on each traction groove 60. Each traction groove 60 is movably fitted with a transmission screw 63. One end of each transmission screw 63 movably passes through the bottom of the support block 12, and a knob 62 is fixedly fitted to one end of each transmission screw 63. A traction block 70, which moves on two guide rods 61, is threaded onto each transmission screw 63. Assembly blocks 71 are fixedly fitted to the symmetrical sides of each traction block 70. Each assembly block 71 is located on one side of the support block 12, and an extension block 72 is fixedly fitted to one end of each assembly block 71. The support block 12 is located between the two extension blocks 72, and a bearing pedal 13 is fixedly fitted to one end of each extension block 72. The bearing pedal 13 is located on one side of the support block 12, and each bearing pedal 13 is provided with a placement groove 20. When the patient sits on the rehabilitation chair body 10, the position is adjusted according to the patient's foot height. Turning knob 62 causes the transmission screw 63 to rotate on the traction block 70, moving the traction block 70 along the two guide rods 61. The traction block 70 then moves the extension block 72 on the assembly block 71, which in turn adjusts the height of the bearing pedal 13 so that the patient's foot can be placed on the placement slot 20. Starting the operating motor 40 causes the movable rod 41 to rotate the second sprocket 42 and the first equal-diameter bevel gear 50. Driven by the chain 43, the first sprocket 31 rotates, causing the adjusting block 73 on the rotating rod 30 to deflect. Simultaneously, the first equal-diameter bevel gear 50 drives the second equal-diameter bevel gear 52 to rotate, which in turn drives the traction gear 53 on the traction rod 51 to rotate.The two traction gears 53 rotate in opposite directions, causing the two support blocks 12 to deflect in opposite directions. This coordinated adjustment of the legs aids in leg rehabilitation.
[0031] Reference Figure 1 and Figure 4 The main body 10 of the rehabilitation chair is symmetrically equipped with handles 11, and the support blocks 12 are symmetrically equipped with straps 80. One strap 80 is equipped with a barbed hook and loop fastener 81, and the other strap 80 is equipped with a rough-edged hook and loop fastener 82 that is bonded to the barbed hook and loop fastener 81. When the patient sits on the main body 10 of the rehabilitation chair, he can improve the stability of the rehabilitation by holding the handles 11 with both hands. The rough-edged hook and loop fastener 82 bonded to the barbed hook and loop fastener 81 can stabilize the patient's legs and improve the standardization of rehabilitation.
[0032] Working principle: The patient sits on the main body 10 of the rehabilitation chair and grips the handles 11 with both hands. The handles are secured by Velcro 82 and Velcro 81, stabilizing the patient's legs and improving the standard of rehabilitation. Depending on the foot height, the knob 62 is turned, causing the transmission screw 63 to rotate on the traction block 70. This moves the traction block 70 along the two guide rods 61, which in turn moves the extension block 72 on the assembly block 71. The extension block 72 then adjusts the height of the support pedal 13, allowing the patient's feet to rest on the placement slot 20. Operation is then initiated. The motor 40 causes the movable rod 41 to drive the second sprocket 42 and the first equal-diameter bevel gear 50 to rotate. Under the transmission of the chain 43, the first sprocket 31 rotates. The first sprocket 31 drives the adjusting block 73 on the rotating rod 30 to deflect by an angle. At the same time, the first equal-diameter bevel gear 50 drives the second equal-diameter bevel gear 52 to rotate. The second equal-diameter bevel gear 52 drives the traction gear 53 on the traction rod 51 to rotate. The two traction gears 53 rotate in opposite directions, causing the two support blocks 12 to deflect in opposite directions. The two legs adjust in a coordinated manner, which helps with leg rehabilitation.
