The threads of the sliding block 12 and the sliding block 2 15 are set in opposite directions, and the friction ring 13 is closely set to the resistance friction wheel 9. By setting the resistance adjustment component 2, the elastic force provided by the spring rod to the friction ring 13 can be conveniently changed, thereby changing the pressure between the friction ring 13 and the resistance friction wheel 9, thereby realizing the adjustment of the training resistance, being able to adapt to different levels of patients, and effectively improving the training and rehabilitation effect of rheumatoid arthritis.
[0031] The base 1 is fixedly connected to a guide rod 17, the sliding block 2 15 and the sliding block 12 are both slidably connected to the guide rod 17, the base 1 is fixedly connected to a bearing seat 18, the rotating shaft 10 is rotatably connected to the bearing seat 18, the base 1 is fixedly connected to a rotating seat 7, the connecting shaft of the driven ratchet sleeve 8 and the resistance friction wheel 9 is rotatably connected to the rotating seat 7, the base 1 is fixedly connected to a support 15, the screw rod 4 is rotatably connected to the support 15, the two ends of the spring rod 14 are respectively hingedly connected to the friction ring 13 and the sliding block 12, the two ends of the spring rod 2 16 are respectively hingedly connected to the friction ring 13 and the sliding block 2 15, the spring rod 14 and the spring rod 2 16 are symmetrically arranged on both sides of the friction ring 13, the pedal assembly 3 includes a movable seat 20, a foot pedal 21, and a foot pedal 2 1 is rotatably connected to the moving seat 20, a return spring 22 is provided between the foot pedal 21 and the moving seat 20, a strap for fixing the foot is provided on the foot pedal 21, a threaded block 24 is fixedly connected to the bottom of the moving seat 20, and the threaded block 24 is threadedly connected to the screw rod 4. When the threaded block 24 moves, the screw rod 4 is driven to rotate, and a guide rail 23 is fixedly connected to the base 1, and the moving seat 20 is slidably connected to the guide rail 23. By setting the foot pedal assembly 3, a reciprocating training process is provided for the patient, and the movement of the leg is converted into the rotation of the resistance friction wheel 9 through the threaded block 24 and the screw rod 4, thereby facilitating the provision of unidirectional training resistance for rehabilitation training. The elastic force of the return spring 22 is conducive to keeping the foot pedal 21 in an inclined state, facilitating the fit between the patient's foot and the foot pedal 21, and facilitating the exertion of force during training.
[0032] Working principle: When a rheumatic joint patient is undergoing rehabilitation training, the patient sits on the base 1, places both feet on the foot pedal 21, and uses the straps on the foot pedal 21 to fix the feet on the foot pedal 21. Then the patient pushes the foot pedal 21 hard, so that the foot pedal 21 and the movable seat 20 move along the guide rail 23. The guide rail 23 moves while driving the screw rod 4 to move. The threaded block 24 drives the screw rod 4 to rotate through the threaded action with the screw rod 4. The screw rod 4 drives the one-way ratchet 6 to rotate. When the patient pushes the foot pedal 21 forward, the foot pedal 21 and the movable seat 20 move along the guide rail 23. When the patient is stretching his legs, the one-way ratchet 6 rotates in the opposite direction. At this time, the one-way ratchet 6 rotates idly in the driven ratchet sleeve 8, and the driven ratchet sleeve 8 drives the resistance friction wheel 9 to rotate together. The friction between the friction ring 13 and the resistance friction wheel 9 hinders the rotation of the resistance friction wheel 9, thereby providing movement resistance to the patient's leg extension movement, thereby achieving an auxiliary effect on joint rehabilitation. When the patient performs leg retraction movement, the one-way ratchet 6 rotates in the opposite direction. At this time, the one-way ratchet 6 rotates idly in the driven ratchet sleeve 8, and the friction between the friction ring 13 and the resistance friction wheel 9 does not affect the leg retraction movement.
[0033] When it is necessary to adjust the resistance of training, the staff manually turns the adjustment handle 19, and the adjustment handle 19 drives the rotating shaft 10 to rotate, and then drives the threaded rod 11 to rotate, so that the sliding block 12 and the sliding block 2 15 can slide along the guide rod 17. Since the threads between the sliding block 12 and the sliding block 2 15 are set in opposite directions, the sliding block 12 and the sliding block 2 15 can move relatively close to or away from each other, thereby changing the length and elasticity of the spring rod 14 and the spring rod 2 16, so that the pressure between the friction ring 13 and the resistance friction wheel 9 changes, thereby realizing the adjustment of the friction force between the friction ring 13 and the resistance friction wheel 9, and then being able to adjust the resistance of training, so that the device can adapt to patients with rheumatic joints of different degrees.
[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
