One end of a crank 4 or a second crank 6 is hinged with a support rod 8, the middle of the first connecting rod 7 is hinged with a support rod 9, and the end of the support rod 9 away from the first connecting rod 7 is hinged with the base 1 , the first connecting rod 7 is fixedly connected with a fixing frame 10, the fixing frame 10 is provided with a foot pedal 11, the base 1 is slidably connected with a guide block 12 front and rear, and the first connecting rod 7 It is vertically slidably connected with the guide block 12, the base 1 is rotatably connected with an L-shaped swing rod 13 that can cooperate with the first cam 3 or the second cam 3, and the base 1 is slidably connected with the L-shaped swing rod 13. The first slider 14 matched with the swing rod 13, the first slider 14 slides along the tangential direction of the rotation of the L-shaped swing rod 13, the swing arm 15 is hinged on the first slider 14, and the swing rod A guide groove 44 is formed on the 15 , and the first connecting rod 7 can slide along the guide groove 44 .

Rehabilitation is a continuous process that requires long-term and persistent training. The limbs and joints and walking training are suitable for hemiplegic patients who cannot fully move their limbs, or who limit limb movement due to muscle spasms. The purpose is to promote the recovery of paralyzed limbs and prevent joints. contractures. The device uses the upper limb exercise device to exercise the upper limb joints of the patient, and uses the walking exercise device to exercise the lower limb joints; as shown in Figure 4, the working process of the walking exercise device is as follows: the drive shaft 2 is driven by the power mechanism and drives The first crank 4 rotates, the first crank 4, the first connecting rod 7, the support rod 9 and the base 1 constitute a crank rocker mechanism, the base 1 is fixed as a frame, the first crank 4 rotates as a crank, and the support rod 9 as a rocker to swing back and forth, the device uses the motion trajectory of the hinge point between the first link 7 and the support rod 8 to move the patient's lower extremity joints. The motion trajectory of this hinge point is an oval trajectory, and the support rod 8 Under the limiting action of the guide block 12, the guide block 12 moves vertically up and down, and at the same time, the guide block 12 moves left and right on the base 1, and the patient's feet are placed on the footboard 11 to form a walking motion. The movement situation, as shown in FIG. 7 , because the structures on the first crank 4 and the second crank 6 are the same and the first crank 4 and the second crank 6 are symmetrical in the center, the two feet of the patient are placed on the footrest 11. The movement is like walking and the posture is always reciprocating and alternating; as shown in Figure 3, the working process of the upper limb exercise device is: the hinge pin of the first link 7 and the support rod 8 slides in the guide groove 44, when the first link 7 and the hinge pin of the support rod 8 slide When the position of the slider 14 is fixed, the first link 7 drives the swing arm 15 to swing, while the first cam 3 rotates and drives the swing rod 13 to rotate. When the swing rod 13 rotates clockwise, it will push the first slider 14 upward. At this time, the swing arm 15 also rises as a whole and the swing angle of the swing arm 15 becomes larger. When the swing rod 13 rotates counterclockwise, it will lose cooperation with the first slider 14. At this time, the swing arm 15 falls as a whole and the swing angle become smaller.

In addition, the rocker arm 15 can be hinged with the first link 7, and the first cam 3 and the second cam 5 can be designed according to the sliding position of the first slider 14 on the base 1 to play a stable role, or they can be removed directly. The first cam 3, the second cam 5 and the swing rod 13 driven by them, the hinge point between the first connecting rod 7 and the swing arm 15 also has an oval movement track when the first crank 4 rotates. The points are all fixed points, and each fixed point corresponds to the swinging angle of a swing arm 15 and the sliding position of the first slider 14 on the base 1, so that the swing arm 15 will also form a circular motion trajectory. At this time, the patient's upper limb joints can be exercised.

Wherein, in order to be more coordinated with the walking posture of the human body, the center between the first cam 3 and the second cam 5 and between the first crank 4 and the second crank 6 is centrally symmetrical.

In combination with the above, in order to enable the patient's finger joints to be exercised, the base 1 is fixedly connected with a guard plate 16, and the first slider 14 is fixedly connected with a positioning rod 17, and the positioning rod 17 A finger positioning bracket 18 is fixedly connected through the protective plate 16 upward. According to the two embodiments of the swing arm 15 described above, the first sliding block 14 will move up and down, so the positioning rod 17 and the finger positioning frame 18 that are fixedly connected to the first sliding block 14 will reciprocate up and down. The arm is placed on the guard plate 16, and the fingers are separately positioned on the finger positioning frame 18. With the up and down movement of the finger positioning frame 18, the patient's finger joints will be moved.
