Description

Technical Field

[0001] The invention relates to the technical field of knee joint exercise, in particular to a knee joint exercise and correction device. Background Art

[0002] The knee joint is a large and complex joint in the human body. It bears almost the entire body weight while also undertaking various leg movements. Therefore, knee joint injuries commonly occur during various sports. In order to improve and regulate the knee joint, a knee joint exercise and correction device is needed. The knee joint exercise and correction device is a rapid detection technology that is widely used in medical rehabilitation, physical exercise and other fields. The existing knee joint exercise and correction device does not stabilize the back of the knee, and is easily dislocated during the correction process, resulting in not only poor correction effect but also possible secondary injury. In addition, the existing device is designed for the patient himself, and the patient can quickly remove it by himself when there is no one around.

[0003] The knee joint exercise and correction device mainly comprises a drive motor, a spring, a forward and reverse threaded rod, a sponge, and an elastic band. Its working principle is that a control device causes the drive motor to rotate the forward and reverse threaded rod, which in turn drives a connecting rod threadedly connected to the forward and reverse threaded rod to slide a slider and a first support rod and a second support rod connected at the upper end. A first fixing member is fixedly connected between the first support rod and the second support rod. The first fixing member and the elastic band are fixed by a second bolt. Under the action of the drive motor, the elastic band is straightened. The knee is placed on the elastic band, and the second fixing member at the lower end of the splint is placed in the mounting slot and fixed with the first bolt. The drive motor drives the forward and reverse threaded rod to rotate. At this time, the elastic band is downwardly moved under the action of the distance and leg pressure, wrapping the back of the knee. The sides of the knee come into contact with the sponge inside the splint, thereby exercising and correcting the knee. When the knee needs to be removed as soon as possible and there is no one to help, a quick release mechanism is provided to pull a clamping block provided on the outer side of the threaded sleeve out of the clamping slot. Under the action of the spring, the clamping block slides out along the second slide slot, thereby quickly removing the knee. Summary of the Invention
