[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system and uses drugs, surgery and physical methods to maintain and develop the normal shape and function of this system. In orthopedic care, it is necessary to exercise the knee joint.

[0003] A knee joint flexion and extension exercise board, with publication number CN219440585U, specifically relates to the field of medical devices. It includes a base plate, connecting seats, a first support plate, a second support plate, side plates, a support platform, a support block, a flexion and extension mechanism, a follower plate, and a telescopic rod. Connecting seats are symmetrically welded to one end of the base plate, and two connecting seats are connected to one end of the first support plate. The other end of the first support plate is movably connected to the second support plate. Side plates are symmetrically welded to the second support plate, and a telescopic rod is installed on one side of each side plate. A support platform and a support block are symmetrically installed on the base plate, and a flexion and extension mechanism is installed on the support platform, connected to one end of a telescopic rod. This invention assists patients in flexion and extension exercises, facilitating flexible training of stiff knee joints. It allows for assisted flexion and extension training, and ultimately enables patients to train independently, providing a gradual and progressive training experience, improving the patient's recovery mood, and avoiding secondary injuries. However, the existing devices still have shortcomings. The existing devices have a complex structure and require motor assistance, which results in high costs and maintenance time. Furthermore, the existing devices cannot control the exercise force when exercising the knee joint and lack an adjustment mechanism. Therefore, we propose a knee joint exercise flexion and extension board to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 One embodiment of this utility model is a knee joint exercise flexion and extension board, including a fixed base 1, a flexion and extension mechanism 2 provided on the surface of the fixed base 1, and an adjustment mechanism 3 provided on the surface of the flexion and extension mechanism 2.

[0025] The bending and extending mechanism 2 includes a first fixing block 210, which is fixed to the surface of the fixing base 1. A bolt 220 is inserted into the first fixing block 210. A rubber pad 230 is fixed to the surface of the fixing base 1. A second fixing block 240 is inserted into the interior of the fixing base 1. A third fixing block 250 is hinged to the interior of the second fixing block 240 by a torsion spring. A rubber block 260 is fixed to the surface of the third fixing block 250. An elastic strap 270 is fixed to the surface of the third fixing block 250.

[0026] The adjustment mechanism 3 includes a fourth fixing block 310, which is fixed to the bottom end of the second fixing block 240. A connecting rod 320 is inserted inside the fourth fixing block 310. A rotating block 330 is provided on the surface of the connecting rod 320, and a telescopic spring 340 is provided on the surface of the connecting rod 320.

[0027] The fixed base 1 is equipped with a slide rail inside, and the second fixed block 240 is equipped with a slider on its side. The slider is inserted into the slide rail of the fixed base 1, and the second fixed block 240 is inserted into the fixed base 1. This structure makes the second fixed block 240 slide more smoothly inside the fixed base 1.

[0028] The side of the fixing base 1 away from the third fixing block 250 has an arc-shaped structure, so that the device will not poke the patient when it comes into contact with the patient, making the patient more comfortable. Four sets of bolts 220 are provided on the side of the fixing base 1, so that the four sets of bolts 220 can fix the fixing base 1 more stably. The rubber pad 230 is fixed on the surface of the fixing base 1. The rubber pad 230 is located at the bottom of the fixing base 1, increasing the friction and also playing a cushioning effect, so that the fixing base 1 will not produce abnormal noise when it comes into contact with the plane. Rubber blocks 260 are evenly fixed on the surface of the third fixing block 250 at equal intervals. The rubber blocks 260 have a strip structure, increasing the friction, so that the foot will not slip off the third fixing block 250 when stepping on it.

[0029] The surface of the connecting rod 320 is provided with threads, and the interior of the rotating block 330 is provided with a threaded hole that matches the connecting rod 320. The connecting rod 320 is inserted into the rotating block 330. When the connecting rod 320 rotates and moves, it can adjust the compression degree of the telescopic spring 340, thereby adjusting the flexion and extension force of the device. The side of the telescopic spring 340 near the fourth fixed block 310 is fixedly connected to the fourth fixed block 310, and the side of the telescopic spring 340 away from the fourth fixed block 310 is fixedly connected to the fixed seat 1, so that the second fixed block 240 can quickly return to its original position, which is convenient for the next flexion and extension, and at the same time, it provides a force for flexion and extension, which is convenient for exercising the knee joint.

[0030] Working principle: When the device is working, the first fixing block 210 fixes the fixing seat 1 on the plane. The foot is placed on the third fixing block 250 and fixed with the elastic strap 270. The thigh is placed on the fixing seat 1, and then a flexion and extension movement is performed. The third fixing block 250 can rotate with the flexion and extension under the action of the torsion spring, and will return to its original position after use. When the leg extends, the second fixing block 240 moves and the telescopic spring 340 expands. Then, when the leg flexes, it will quickly return to its original position under the action of the telescopic spring 340, completing a flexion and extension movement. The telescopic spring 340 will provide a pulling force when the leg extends, so that the device can fully exercise the knee joint. Rotating the rotating block 330 can move the rotating block 330 and adjust the compression degree of the telescopic spring 340, thereby adjusting the flexion and extension force. The device can achieve the best exercise effect according to the usage. The above is the complete working principle of this utility model.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
