On the right side surface of the block one 25, the right end of the right column pin five is rotatably connected with the left side of the right slider two 28, the right connecting rod 30 is L-shaped, and one side of the L shape slides with the inner hole of the right slider two 28. For connection, the second right locking bolt 29 is installed on the threaded hole provided on the second right sliding block 28 that penetrates to the center. By tightening the second right locking bolt 29, the second right sliding block 28 is fixed on one side of the right connecting rod 30, It is used to realize that the fixed position of the right slider 28 on one side of the right connecting rod 30 can be adjusted, the L-shaped corner of the right connecting rod 30 is rotatably connected with the left end of the right column pin six 31, and the right end of the right column pin six 31 is fixed on the right On the right boss 1 321 provided on the column pin frame 32, the right column pin frame 32 is fixed on the base 1, and the other end of the L-shaped other side of the right connecting rod 30 is connected to the right connecting rod 3 through the right column pin 7 34. The upper end of 33 forms a hinged connection.

[0031]The lower end of the third right link 33 forms a hinge connection with the rear end of the right link four 36 through the right column pin eight 35, and the front end of the right link four 36 is fixedly connected with the right end of the right foot rotating shaft 37, and the right foot rotating shaft 37 The lower end of the right foot connecting frame 40 is fixed at the left end of the right foot connecting frame 40, and the right foot connecting shaft 401 extending horizontally to the left, which is arranged on the upper end of the right foot connecting frame 40, is rotated and connected to the right boss two 421 arranged on the lower surface of the right foot support plate 42, and the right foot support The plate 42 is provided with a right foot strap 41, the right foot rotating shaft 37 is installed in the inner hole of the right bearing bearing seat 39, the right bearing bearing seat 39 is fixed on the upper surface of the right bearing seat bracket 38, the right bearing seat bracket 38 The lower surface is fixed on the base 1 .

[0032] The front part of the right upper limb rod 23 is slidably connected with the inner hole of the right palm connecting slider 44, and the lower side of the right palm connecting slider 44 is provided with a front-to-back through incision, which is installed by tightening the right palm connecting slider 44. The third right locking bolt 43 narrows the incision below the right palm connecting slider 44, so that the right palm connecting slider 44 is fixed on the right upper limb rod 23, and the left surface of the right palm connecting slider 44 is provided with a front left. The protruding right beam 441 has a right palm fixing rod 46 fixed on the left front end of the right beam 441 , and a right palm strap 45 is fixed on the right palm fixing rod 46 .

[0033] The right upper and lower limb rehabilitation training mechanism 5 includes a right upper limb rod 23, a right connecting plate 19, a right column 16, a second right connecting rod 17, a right connecting rod 30, a right column pin frame 32, a third right connecting rod 33, Connecting rod four 36, right foot rotating shaft 37, right foot connecting frame 40, right foot support plate 42, right foot strap 41, right bearing bearing seat 39, right bearing seat bracket 38, right palm connecting slider 44, right palm fixing Rod 46, right palm strap 45.

[0034] The patient sits on the seat 2. If the patient's right upper or lower limb can move voluntarily, and the patient's left upper and lower limbs need to be rehabilitated, place the patient's right palm on the right palm fixing rod 46, and tie the right palm tightly. The palm strap 45, loosen the right locking bolt 3 43, and adjust the fixed position of the right palm connecting slider 44 to adapt to the length of the patient's upper limb and make the patient more comfortable. Put the right foot on the right foot support plate 42, fasten the right foot strap 41, loosen the right locking bolt 1 26, adjust the fixed position of the right slider 1 25 on the right link 2 17, and realize the upper limb rehabilitation of the patient. The relationship between the initial position of the exercise and the relative initial position of the lower limb rehabilitation exercise makes the patient more comfortable. Tighten the right locking bolt 1 26, and adjust and fix the patient's left foot in the same way as above. The patient's right upper limb swings up and down, and the right upper limb The rod 23 drives the right link 12 to move, so that the transmission shaft 4 rotates, and the transmission shaft 4 drives the left link 14 to move through the left swing rod 13, so that the left upper limb rod 21 and the right upper limb rod 23 swing up and down in opposite directions. The rod 23 drives the right connecting rod 2 17 to move, the right connecting rod 30 drives the right connecting rod 33 to move, and the right connecting rod 4 36 drives the right foot shaft 37 to rotate, so that the patient's right lower extremity moves, the same through the left upper limb rod 21 The patient's left lower extremity is driven by the intermediate transmission, so that the patient's limbs are similar to the gait movement.

[0035] If the patient's right upper or lower limb has motor dysfunction and the left upper or lower limb can move voluntarily, the patient's left upper or lower limb will drive the right upper or lower limb for rehabilitation through the above-mentioned transmission route.

[0036] If the rehabilitation range of motion of one lower limb of the patient is not coordinated with the range of motion of the upper limb, for example, when the range of motion of the upper limb is large and the range of motion of the lower limb is small, the right locking bolt 29 can be loosened, and the right slider 228 can be adjusted on the right connecting rod. The fixed position on one side of the 30, if the right slider two 28 is adjusted in the direction of the corner position of one side of the right connecting rod 30, the motion range of the patient's lower extremities will become larger, otherwise the motion range of the lower extremities will become smaller to accommodate The needs of patients with different conditions.
