[0027] In this embodiment, a plurality of suction cups are provided at the lower end surface of the bottom plate 100. Through the arrangement of the suction cups, the bottom plate 100 can be conveniently installed on the ground, so that the friction between the rehabilitation exercise device and the ground is increased, so that it will not shake when in use. A rotatable lower shaft 111 is provided on the lower limb training part 110, a foot pedal 112 is provided on the lower shaft 111, a rubber sleeve 113 is provided on the foot pedal 112, and a damping device for increasing the rotation resistance of the lower shaft 111 is provided in the lower limb training part 110. When the patient needs to undergo postoperative rehabilitation, the patient sits on the cushion 140, places the lower limbs between the foot pedal 112 and the rubber sleeve 113, and rotates the lower shaft 111 to exercise the lower limbs to restore the muscles of the patient's lower limbs. Among them, by setting the lower limb training part 110 and the upper limb training part 121, the patient's upper limbs can be trained by rotating the upper limb training part 121 while the lower limbs are being trained. Compared with the existing embodiment, this embodiment can make it easier for the patient to train the upper and lower limbs, and is more suitable for the actual physical condition of the patient after a long period of recuperation. Among them, by the movable arrangement of the support seat 130 on the bottom plate 100 and the movable arrangement of the seat cushion 140 on the support seat 130, the distance between the patient on the support seat 130 and the upper limb training part 121 and the lower limb training part 110 can be adjusted, so that the patient can more conveniently contact the upper limb training part 121 and the lower limb training part 110, making this embodiment more applicable; The angle of the backrest 150 can be adjusted to adjust the angle between the backrest 150 and the seat cushion 140 according to the specific needs of the patient, so that the patient's back fits the backrest 150, and the patient can exercise in different postures to avoid exercising in one posture for a long time, which may cause discomfort to the patient's back. The T-shaped slide groove 500 and the T-shaped slider 520 are provided so that the support seat 130 can be restricted when moving on the bottom plate 100, that is, it can only move along the extension direction of the T-shaped slide groove 500, so that the support seat 130 moves relatively smoothly without shaking, and the cushion 140 located on the support seat 130 remains stable, which is convenient for the patient to sit on it; A block for blocking the opening of the T-shaped slide groove 500 is provided on the bottom plate 100 , thereby preventing the T-shaped slide block 520 from slipping out of the T-shaped slide groove 500 when moving.

[0029] Among them, through the arrangement of the locking hole 511 and the bolt 521, when it is necessary to fix the support seat 130 and the bolt 521, the bolt 521 can be rotated so that the other end of the bolt 521 extends into the locking hole 511. When it is necessary to move the support seat 130, the bolt 521 can be rotated in the opposite direction so that the other end of the bolt 521 extends out of the locking hole 511. At this time, the support seat 130 can be moved, and the distance between the support seat 130 and the upper limb training part 121 and the lower limb training part 110 can be adjusted. In actual use of this embodiment, the protruding end of the bolt 521 is provided with a hand-tightening portion 522. Through the provision of the hand-tightening portion 522, when the bolt 521 needs to be turned, there is no need to look for tools such as a wrench, which is more convenient to use.

[0030] like Figure 1-4 As shown, in this embodiment, the upper end surface of the support seat 130 is provided with a lifting chamber 400 with an upper end opening along its height direction, and a cover plate 410 for sealing the opening of the lifting chamber 400 is provided, and the seat cushion 140 is provided with a connecting rod 420 that passes through the cover plate 410 and extends into the lifting chamber 400, and one end of the connecting rod 420 is provided with a lifting block 421 that fits with the inner wall of the lifting chamber 400, and the lifting block 421 can be rotatably and movably set in the lifting chamber 400, and the lifting chamber 400 is also provided with a retaining component for keeping the lifting block 421 in the current position.

[0031] In this embodiment, when the height of the seat cushion 140 from the ground needs to be adjusted, the lifting block 421 can be moved in the lifting chamber 400. When it is moved to the required height, the lifting block 421 is kept in the current position by the holding assembly, thereby fixing the height of the seat cushion 140 from the ground. The lifting block 421 is arranged to fit the inner wall of the lifting chamber 400, so that the lifting block 421 can move in the height direction of the lifting chamber 400. The cross-sections of the lifting chamber 400 and the lifting block 421 are adapted to be circular. With this structure, the lifting block 421 can rotate in the lifting chamber 400. During assembly, the cover plate 410 is first sleeved on the connecting rod 420, and then the lifting block 421 is connected to the lower end of the connecting rod 420 by welding, and finally the cover plate 410 is installed at the upper end opening of the lifting chamber 400 by screws; Among them, the cover plate 410 can also limit the connecting rod 420, that is, a limiting hole for the connecting rod 420 to pass through is provided on the cover plate 410, and the connecting rod 420 is close to the inner wall of the limiting hole. The connecting rod 420 can move and rotate in the limiting hole. During this process, the connecting rod 420 will not be skewed, so that the seat cushion 140 can always maintain a horizontal state, which is convenient for patients to sit on.

[0032] like Figure 1-5 As shown, in the present embodiment, one side surface of the support seat 130 is provided with a movable groove 401 connected to the lifting chamber 400 along its height direction, and the other side surface of the support seat 130 is provided with a plurality of locking grooves 402 along its height direction, and the locking grooves 402 connect the lifting chamber 400 and the movable groove 401, and the retaining assembly includes a locking block 422 arranged on the lifting block 421, and the locking block 422 can be slidably arranged in the movable groove 401 and the locking groove 402, and the locking block 422 is located in the movable groove 401 and slides to adjust the height of the seat cushion 140 from the ground, and the locking block 422 is located in the locking groove 402 to maintain the height of the seat cushion 140 from the ground.

[0033] In this embodiment, the locking groove 402 is divided into a horizontal part and a vertical part. When the height of the seat cushion 140 from the ground needs to be moved, the seat cushion 140 is moved upward to drive the connecting rod 420 to move upward, so that the locking block 422 moves upward from the vertical part to the horizontal part, and the locking block 422 is rotated to make it transfer into the moving groove 401. When it moves to the required position, the locking block 422 is rotated again to move it to the horizontal part, and the seat cushion 140 is released. Under the action of gravity, the locking block 422 is stuck in the vertical part. At this time, the positions of the lifting block 421 and the locking block 422 are fixed, and finally the position of the seat cushion 140 is fixed; The moving groove 401 is connected to the upper opening of the lifting chamber 400 . This structure facilitates the installation of the lifting block 421 and the locking block 422 in the lifting chamber 400 .

[0034] like Figure 1-2As shown, in this embodiment, the upper end surface of the seat cushion 140 is provided with a rotation groove 211 along its height direction, and a fixing rod 210 is provided in the rotation groove 211. The backrest 150 is provided with a connecting portion 200 passing through the fixing rod 210. The backrest 150 can be rotatably arranged around the fixing rod 210. The connecting portion 200 is evenly provided with a plurality of connecting holes 202 along the circumference of the fixing rod 210, and the seat cushion 140 is provided with a fixing component for fixing the rotating connecting portion 200.

[0035] In this embodiment, a mounting hole 201 is provided in the connecting portion 200 for the fixing rod 210 to pass through, thereby realizing the rotation of the backrest 150 around the fixing rod 210. When the angle between the backrest 150 and the seat cushion 140 needs to be adjusted, the fixing component is operated to extend out of the connecting hole 202. At this time, the backrest 150 can be rotated to a desired angle, and the fixing component is operated again to extend into the connecting hole 202. At this time, the angle of the backrest 150 is fixed, so that the patient can exercise in different postures. In this embodiment, a soft cushion is provided on the seat cushion 140 , and the provision of the soft cushion can make the patient feel more comfortable when the back contacts the backrest 150 .

[0036] like Figure 1-4 As shown, in the present embodiment, a mounting cavity 300 with an opening at one end is provided on one side of the seat cushion 140, a blocking plate 220 is provided at the opening of the mounting cavity 300, a through hole is provided in the mounting cavity 300 corresponding to the connecting hole 202, and the fixing assembly includes a movable plate 310 arranged in the mounting cavity 300 and fitted with an inner wall thereof, a locking rod 311 is provided at one end of the movable plate 310 and extends into the connecting hole 202 through the through hole, an operating rod 221 is provided at the other end of the movable plate 310, one end of the operating rod 221 is extended through the blocking plate 220, a spring 312 is sleeved on the operating rod 221, and the spring 312 is used to push the connecting rod 420 to extend into the connecting hole 202.

[0037] In this embodiment, the cross-sections of the mounting cavity 300 and the movable plate 310 are adaptive rectangles. With this structure, the movable plate 310 can only move in the mounting cavity 300 but cannot rotate, so that the locking rod 311 can maintain the state of aligning the through hole and the connecting hole 202. When it is necessary to adjust the angle between the backrest 150 and the seat cushion 140, the operating rod 221 is pulled, the spring 312 is compressed by the movable plate 310, the locking rod 311 extends out of the connecting hole 202 and retracts into the mounting cavity 300. At this time, the seat cushion 140 is rotated to a suitable angle, and the connecting rod 420 is released. Under the thrust of the spring 312, the movable plate 310 moves toward the connecting hole 202, and the locking rod 311 passes through the through hole and extends into the connecting hole 202 to fix the rotating backrest 150. During assembly, first, install the moving plate 310 , the locking rod 311 and the operating rod 221 in the installation cavity 300 , then sleeve the spring 312 on the operating rod 221 , and finally fix the blocking plate 220 at the opening of the installation cavity 300 by means of the bolt 521 .

[0039] In this embodiment, the gripping portion 222 is mounted on the protruding end of the operating rod 221 by welding, thereby facilitating pulling the operating rod 221 outside the mounting cavity 300 .

[0040] Working principle: When the patient needs to undergo postoperative rehabilitation, first, according to the patient's specific needs, loosen the bolt 521 to disengage the bolt 521 from the locking hole 511, move the support seat 130 to a suitable position, and then rotate the seat cushion 140 to drive the locking block 422 to slide from the locking groove 402 into the moving groove 401. When moving to the required height, rotate the seat cushion 140 to drive the locking block 422 into the locking groove 402, so that the seat cushion 140 is adjusted to a height suitable for the patient, pull the operating rod 221, and make the locking rod 311 extend out of the connecting hole 202 and retract into the installation cavity 300. At this time, rotate the backrest 150 to a suitable angle, loosen the connecting rod 420, and under the thrust of the spring 312, the movable plate 310 moves toward the connecting hole 202, and the locking rod 311 passes through the through hole and extends into the connecting hole 202 to fix the rotating backrest 150. At this time, the angle adjustment of the backrest 150 is completed, and the patient can insert the sole of the foot between the footrest 112 and the rubber sleeve 113, and rotate the lower shaft 111 to exercise the patient's lower limbs. While exercising the lower limbs, the patient can also hold the upper limb training part 121 and rotate it to exercise the patient's upper limbs.
