Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 - 4 , a knee osteoarthritis exercise rehabilitation device, which includes a support device 1. A transmission device 2 is arranged on one side of the support device 1, and an adjustment device 3 is arranged on one side of the transmission device 2.

[0026] In this embodiment: The support device 1 includes a base 101. A main body frame 102 is rotatably arranged on the top of the base 101. A motor 103 is installed behind the main body frame 102. A pedal 104 is rotatably arranged at the bottom of the main body frame 102. A crank 105 is rotatably arranged at the top of the main body frame 102. The main body frame 102 is connected to the base 101 by a bearing, and the motor 103 is bolted to the base 101. When it is necessary to change the inclination angles of the crank 105 and the pedal 104, the base 101 supports the motor 103 to drive the main body frame 102 to rotate, driving the crank 105 and the pedal 104 to rotate, and completing the adjustment of the inclination angle, facilitating the user to exert force more fully;

[0027] In this embodiment: The transmission device 2 includes a first pulley 201. A second pulley 202 is arranged above the first pulley 201. A third pulley 203 is arranged below the second pulley 202. A bracket 204 is arranged on one side of the third pulley 203. A belt 205 is arranged between the first pulley 201, the second pulley 202 and the third pulley 203. The first pulley 201 and the second pulley 202 are respectively connected to the support device 1 by a key. The user sits on a stool, holds the crank 105 with both hands and shakes it, and pedals the pedal 104 with both feet, driving the first pulley 201 and the second pulley 202 to rotate. During this process, under the connection and transmission of the belt 205, the rotation speeds of the pedal 104 and the crank 105 tend to be synchronized, facilitating the coordinated movement of the user's feet and legs and exercising the knee joint;

[0028] In this embodiment: The adjusting device 3 includes a fixed frame 301. A damping frame 302 is slidably arranged on the top of the fixed frame 301. A damping plate 303 is arranged on one side of the damping frame 302. A spring 304 is fixedly arranged on the side of the damping frame 302 away from the damping plate 303. One end of the spring 304 is fixedly provided with a moving frame 305. A screw rod 306 is arranged at the bottom of the moving frame 305. A handle 307 is arranged at one end of the screw rod 306. The moving frame 305 is slidably connected to the fixed frame 301. The screw rod 306 is rotationally connected to the fixed frame 301 through a bearing. During the rotation of the first pulley 201 and the second pulley 202, the third pulley 203 is synchronously driven to rotate under the support of the bracket 204. The moving frame 305 that supports the spring 304 pushes the damping frame 302 through the elastic force. The damping frame 302 drives the damping plate 303 to closely adhere to the side of the third pulley 203 under the limitation of the fixed frame 301, generating frictional force to hinder the rotation of the third pulley 203, thereby exercising the leg muscles of the user. When it is necessary to adjust the resistance, rotate the handle 307 to drive the screw rod 306 to rotate. The screw rod 306 drives the moving frame 305 to slide along the fixed frame 301. During this process, the length of the spring 304 changes, and the elastic force applied to the damping frame 302 changes synchronously. The pressure of the damping plate 303 on the third pulley 203 changes accordingly, realizing the damping adjustment of the device. Through the design of setting the damping plate 303 to friction the third pulley 203, it is convenient to perform rehabilitation treatment for the problem of insufficient joint muscles of arthritis patients, improving the treatment pertinence of the device. At the same time, the design with adjustable resistance can adapt to users in different situations, further increasing the application range of the device.

[0029] Working principle: The user sits on the stool, holds the crank 105 with both hands and pedals the pedal 104 with both feet, driving the first pulley 201 and the second pulley 202 to rotate. During this process, under the connection and drive of the belt 205, the rotation speeds of the pedal 104 and the crank 105 tend to be synchronized, facilitating the coordinated movement of the user's feet and legs and exercising the knee joints. When it is necessary to change the inclination angle between the crank 105 and the pedal 104, the base 101 supports the motor 103 to drive the main frame 102 to rotate, driving the crank 105 and the pedal 104 to rotate, completing the adjustment of the inclination angle and facilitating the user to exert force more fully. In order to exercise the muscle strength of the user and enable the knee joints to obtain sufficient muscle support, resistance needs to be applied to the moving belt 205 during the rehabilitation process. When the first pulley 201 and the second pulley 202 rotate, they synchronously drive the third pulley 203 to rotate under the support of the bracket 204. The moving frame 305 supports the spring 304, and the spring 304 pushes the damping frame 302 through elastic force. The damping frame 302 drives the damping plate 303 to closely adhere to the side of the third pulley 203 under the limit of the fixed frame 301, generating frictional force to hinder the rotation of the third pulley 203, thereby exercising the leg muscles of the user. When it is necessary to adjust the resistance, turning the handle 307 drives the screw 306 to rotate. The screw 306 drives the moving frame 305 to slide along the fixed frame 301. During this process, the length of the spring 304 changes, and the elastic force applied to the damping frame 302 changes synchronously. The pressure of the damping plate 303 on the third pulley 203 changes accordingly, realizing the damping adjustment of the device. Through the design of setting the damping plate 303 to friction the third pulley 203, it is convenient to carry out rehabilitation treatment for the problem of insufficient joint muscles of arthritis patients, improving the treatment pertinence of the device. At the same time, the design of adjustable resistance can adapt to users in different situations, further increasing the application range of the device.
