[0026] Such as Figures 1 to 5As shown in the figure, an adjustable knee joint function exercise device includes a seat plate 1. At the four corners of the bottom surface of the seat plate 1, support legs 2 are fixedly connected. The surface of the support leg 2 is slidably connected with an installation box 3. An activity control component 5 is arranged inside the installation box 3. At the top of the activity control component 5, a foot positioning component 6 for placing the foot is arranged. On the top surface of the installation box 3, a range control component 7 for restricting the moving range of the locking component 4 is installed. More specifically, the patient sits on the surface of the seat plate 1, places the foot on the surface of the foot positioning component 6, and fixes the foot through the foot positioning component 6. By operating the activity control component 5, the foot positioning component 6 can be driven to move, thereby driving the patient's foot to move, making the patient's knee joint bend, so as to exercise the knee joint. Through the range control component 7, the operating range of the activity control component 5 can be controlled, thereby controlling the moving range of the foot positioning component 6 and the patient's foot, and thus controlling the bending range of the patient's knee joint. When the use is completed, the installation box 3 can be slid under the seat plate 1, and the position of the installation box 3 is fixed by the locking component 4, so as to reduce the volume of the device for storage.

[0027] The activity control component 5 includes a motor 501, and the motor 501 is fixedly installed on the inner wall of the installation box 3. The output end of the motor 501 is fixedly connected with a threaded column 502. The surface of the threaded column 502 is threadedly connected with a support frame 503. A limiting rod 504 is fixedly connected to the inner wall of the installation box 3, and the limiting rod 504 is slidably connected with the support frame 503. A limiting groove 505 is formed through the top surface of the installation box 3, and the inner wall of the limiting groove 505 is slidably connected with the surface of the support frame 503. It should be noted that by driving the threaded column 502 to rotate through the motor 501, the support frame 503 is driven to slide along the surface of the limiting rod 504 and the inner wall of the limiting groove 505, thereby driving the foot positioning component 6 to move.

[0028] The foot positioning component 6 includes a support plate 601, and the support plate 601 is fixedly connected to the end of the support frame 503. A binding strap 602 is fixedly connected to the surface of the support plate 601. A magic male sticker 603 is fixedly connected to the end of the binding strap 602. A magic female sticker 604 is fixedly connected to the top surface of the support plate 601. More specifically, the patient's foot is placed on the surface of the support plate 601. The binding strap 602 is wound around the patient's instep, and then the magic male sticker 603 and the magic female sticker 604 are bonded to fix the patient's foot.

[0029] A non-slip strip is fixedly connected to the top surface of the support plate 601, and the non-slip strip is made of rubber material. It should be noted that by setting the non-slip strip made of rubber material, the friction with the patient's sole is increased, so that the patient's sole is not easy to slide.

[0030] The range control component 7 includes a fixed plate 701, and the fixed plate 701 is fixedly connected to the top surface of the mounting box 3. A double-headed screw 702 is rotatably connected to the surface of the fixed plate 701. A knob 703 is fixedly connected to the end of the double-headed screw 702. Two mounting plates 704 are threadedly connected to the surface of the double-headed screw 702. A sliding rod 705 is fixedly connected to the surface of the fixed plate 701, and the sliding rod 705 is slidably connected to the mounting plate 704. A pressure sensor 706 is fixedly installed on the surface of the mounting plate 704. More specifically, when the motor 501 controls the movement of the support frame 503, the support frame 503 will come into contact with the pressure sensor 706. The pressure sensor 706 will detect the pressure. At this time, the motor 501 will control the reverse rotation of the threaded column 502, thereby restricting the movement range of the support frame 503 and the locking component 4. By rotating the knob 703, the double-headed screw 702 is driven to rotate. Under the action of the thread, the mounting plate 704 will be driven to slide along the surface of the sliding rod 705, thereby adjusting the position of the pressure sensor 706, and then the movement range of the support frame 503 and the foot positioning component 6 can be adjusted.

[0031] The locking component 4 includes a plug 401, and the plug 401 is movably inserted into the support leg 2. A fixed ring 402 is fixedly connected to the surface of the plug 401. A spring 403 is fixedly connected between the inner wall of the plug 401 and the support leg 2. Limit strips 404 are fixedly connected to both the left side and the right side of the mounting box 3. A chute 406 is formed on the surface of the support leg 2, and the surface of the limit strip 404 is slidably connected to the inner wall of the chute 406. Two groups of jacks 405 are formed on the surface of the limit strip 404, and the end of the plug 401 is movably inserted into the inner wall of the jack 405. Rollers 8 are provided at the four corners of the bottom surface of the mounting box 3. It should be noted that when exercise is not required, by pulling the fixed ring 402, the plug 401 is driven to move, the spring 403 is stretched, and the end of the plug 401 is separated from the inner wall of the jack 405, so that the limit on the limit strip 404 can be released. Pull the mounting box 3 backward, drive the limit strip 404 to slide along the inner wall of the chute 406, and finally align the front jack 405 with the plug 401. At this time, release the fixed ring 402. Under the elastic force of the spring 403, the plug 401 will be pushed to move and inserted into the inner wall of the front jack 405, thereby limiting the limit strip 404. At this time, the whole mounting box 3 is located below the seat plate 1, thereby reducing the overall volume of the device and facilitating storage.

[0032] In summary: The patient sits on the surface of the seat board 1, places the feet on the surface of the foot positioning component 6, and fixes the feet through the foot positioning component 6. By operating the movement control component 5, the foot positioning component 6 can be driven to move, thereby driving the patient's feet to move, causing the patient's knee joint to bend, so as to exercise the knee joint. The range control component 7 can control the operating range of the movement control component 5, thereby controlling the movement range of the foot positioning component 6 and the patient's feet, and thus controlling the bending range of the patient's knee joint. When the use is completed, the installation box 3 can be slid under the seat board 1, and the locking component 4 is used to fix the position of the installation box 3, so as to reduce the volume of the device for storage. During use, the effect of facilitating the automatic bending exercise of the patient's knee joint is achieved, without relying on the patient's own effort, facilitating the patient to carry out continuous exercise, and being able to control the amplitude of the exercise, making the exercise process more reasonable and effective.
