In this embodiment, when a patient needs knee joint flexion training, the patient sits on the seat 2 and starts the micro motor, at this time, the micro motor drives the cam 6 to rotate and enables the driving shaft 8 at the front side to move upwards, the driving shaft 8 at the front side can drive the driving shaft 8 at the rear side to move synchronously through the guide rod 15 after moving upwards, the driving shaft 8 drives the second driving rod 11 to move upwards after moving upwards, the second driving rod 11 drives the first driving rod 9 and the third driving rod 13 to move upwards through the first driven shaft 10 and the second driven shaft 12 after moving upwards, at this time, the driving shaft 8 drives the second driving rod 11 to move, the first driving rod 9 and the second driving rod 11 to move upwards, and the two first driving rods 9 and the two second driving rods 11 generate upward thrust due to being close to each other, so as to drive the first driven shaft 10 and the second driven shaft 12 to move upwards, and because of the length of first actuating lever 9, the length of the second actuating lever 11 between first driven shaft 10 and the drive shaft 8 all is less than the length of the second actuating lever 11 between drive shaft 8 and the second driven shaft 12, so with the length of first actuating lever 9, the length of the second actuating lever 11 between first driven shaft 10 and the drive shaft 8 all is not less than the length of the second actuating lever 11 between drive shaft 8 and the second driven shaft 12 and compares, this setting is because of the increase of the contained angle of first actuating lever 9 and second actuating lever 11 on first driven shaft 10, thereby make the ascending displacement distance of second actuating lever 11 increase.
When the second driven shaft 12 drives the third driving rod 13 to move upwards, the third driving rod 13 pushes the push plate 16 on the third driven shaft 14 to move, and the push plate 16 pushes the seat plate 2 to move after contacting with the seat plate 2, so that the seat plate 2 is lifted, and the training chair can be suitable for patients with different heights; and in the moving process, the second driven shaft 12 is connected in the sliding groove in a sliding manner, so that the stability in the lifting process is further improved.
When the height of the training chair is adjusted by the patient, the micro motor is turned off, and at the moment, two feet of the patient can just touch the ground; when a patient needs to perform knee bending training, the patient puts the foot to be trained into the corresponding foot blocking plate 4, then takes the other support leg as a force acting point and starts to press down the pressure lever 18, the pressure lever 18 starts to move upwards around the rotating shaft 17 at the moment, so that the pedal 3 is driven by the traction rope 19 to move leftwards, and the foot is gradually bent along with the movement of the pedal 3 at the moment, so that the knee joint bending training is realized; in addition, different training intensities can be selected according to the illness state of the patient in the moving process of the pedal 3, and after the training intensity is selected by the patient, the upper and lower stop levers 20 at the position of the compression lever 18 are rotated to the motion trail of the compression lever 18, so that the position of the compression lever 18 is limited, the training intensity is fixed, the labor intensity of the patient is reduced, and the patient can conveniently train by himself. The two stop rods 20 above and below the compression rod 18 can also protect the compression rod 18, so that the situation that the compression rod 18 moves upwards or downwards suddenly due to external force to cause secondary damage to a patient is avoided, and the safety of the patient is improved. When the patient finishes training, the stop lever 20 can be rotated and the press lever 18 is lifted upwards, and the pedal 3 is reset under the action of self gravity.
If the patient does not need to carry out knee joint flexion training, the feet are placed on the left side of the foot blocking plate 4 and abut against the foot blocking plate 4, then the binding belts on the two sides of the foot blocking plate 4 are bound on the calf (tibiofibula) of the patient, so that the feet of the patient are fixed on the pedal 3, and then the seat plate 2 is lifted by starting the micro motor, so that the gap of the knee joint is increased, the patient can carry out the training of traction separation of the joint capsule, and the function of the training chair is increased; the training chair is simple in structure and convenient to manufacture on a large scale, so that the product cost is greatly reduced, and the training chair is suitable for common people.
The above are merely examples of the present invention, and common general knowledge of known specific structures and/or characteristics of the embodiments is not described herein in an excessive amount. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
