[0029] Please refer to Figures 1 to 6 As shown, a pneumatic limb rehabilitation training device of the present utility model includes a training chair 1. A slide groove 11 is opened at the top of the training chair 1. A pedal 12 is slidably installed on the inner side wall of the slide groove 11. One end of the training chair 1 is further provided with a pneumatic drive component 2. The output end of the pneumatic drive component 2 is connected to the pedal 12 for driving the pedal 12 to slide along the length direction of the training chair 1. It further includes:

[0031] A pulley block 4 is installed on the adjusting frame 3. A traction rope 41 is carried on the outer wall of the pulley block 4. One end of the traction rope 41 is fixedly connected with a tension handle 42;

[0032] An assembled counterweight component 5 is installed at the other end of the traction rope 41. In the actual implementation process, the training chair 1 is placed on the ground. Personnel can lie on the training chair 1 for training operations. When leg exercises are needed, the pneumatic drive component 2 is started. The pneumatic drive component 2 pushes the pedal 12 to move, causing the patient's legs to bend. In the process of reciprocating bending and stretching, the purpose of exercise is achieved. The adjusting frame 3 can be lifted or lowered for different personnel to be used. When upper limb exercises are needed, the tension handle 42 is pulled, driving the traction rope 41 to slide in the pulley block 4, completing the lifting of the assembled counterweight component 5, thereby realizing the weight-bearing exercise of the upper limbs.

[0033] Optionally, the pneumatic driving component 2 includes an air pipe 21 fixedly installed at one end of the training chair 1. A piston 22 is slidably connected to the inner side wall of the air pipe 21. One side of the piston 22 is fixedly connected to a piston rod 23, and one end of the piston rod 23 is fixedly connected to the pedal 12. In the actual implementation process, when gas is injected into the air pipe 21, the piston 22 can be pushed to move, thereby driving the piston rod 23 to push the pedal 12 to move, causing the legs of the exerciser to bend. When the gas in the air pipe 21 is discharged, the person can gradually stretch the legs for exercise.

[0034] Optionally, the pneumatic driving component 2 further includes an air pump 24. The output end of the air pump 24 is fixedly connected to two hoses 25, and the hoses 25 are communicated with the air pipe 21. In the actual implementation process, the air pump 24 works to inject gas into the air pipe 21 through the hoses 25.

[0035] Optionally, a pressure valve 26 is further provided at one end of the air pipe 21 close to the hose 25. The pressure valve 26 is used to monitor the air pressure in the air pipe 21. In the actual implementation process, the pressure valve can monitor the air pressure in the air pipe 21 to avoid damage to the exerciser caused by overpressure.

[0036] Optionally, the pedal 12 is slidably installed on the inner wall of the chute 11 through a slider. In the actual implementation process, the pedal 12 can slide horizontally when slidably installed in the chute 11.

A fixing bolt 32 is also threadedly connected to the side wall of the training chair 1. One end of the fixing bolt 32 passing through the training chair 1 is in plug-in fit with the jack on the side wall of the inserting rod 31. In the actual implementation process, when the height of the adjusting frame 3 needs to be adjusted, the fixing bolt 32 is taken out, and then the adjusting frame 3 can be slid to complete the height adjustment. After the adjustment is completed, the fixing bolt 32 is inserted into the inserting rod 31 to limit the sliding of the inserting rod 31, thereby completing the fixing of the adjusting frame 3.

[0038] Optionally, the assembled counterweight assembly 5 includes counterweight blocks 51. The bottom of the counterweight blocks 51 has two inserting blocks 52. Slots are provided on the side walls of the counterweight blocks 51 and the inserting blocks 52, and a limit bolt 53 is threadedly connected in the slots. When the limit bolt 53 is inserted into the counterweight blocks 51 and the inserting blocks 52, two adjacent counterweight blocks 51 are assembled into one body. In the actual implementation process, for different training intensities, different numbers of counterweight blocks 51 are assembled. During assembly, the inserting block 52 at the bottom of the upper counterweight block 51 is inserted into the slot on the lower counterweight block 51, and then the limit bolt 53 is inserted through the counterweight block 51 and threadedly connected to the inserting block 52 for fixation, thereby completing the assembly of the counterweight blocks 51.
