Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to an elbow flexion training device. Background Art

[0002] The elbow joint is an important part of the body. It consists of the lower end of the humerus, the upper end of the ulna and the radius, and includes three joints. The normal flexion and extension range of the elbow joint is between 0 and 140 degrees. The physiological functions of the elbow joint are mainly flexion and extension and rotation of the forearm. Damage to the elbow joint often affects a person's daily life, study, work and leisure activities.

[0003] Existing devices for exercising elbow joints usually include an upper arm sleeve, a forearm sleeve and an elastic connection bracket. When in use, the upper arm and forearm need to be respectively put on the upper arm sleeve and the forearm sleeve, and then the elastic connection bracket is bent by bending the arm to achieve the purpose of exercising the elbow joint. Although this device has a simple structure, it is troublesome to use. The upper arm sleeve and the forearm sleeve need to be carefully put on. When the force is released after the arm is bent, the elastic connection bracket will quickly reset, which is easy to strain the elbow joint. In addition, the elastic force of the elastic connection bracket is not adjustable, and it cannot adapt to people with different physiques. Utility Model Content
