Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sports training equipment, in particular to an elastic device with variable resistance. Background Art
[0002] With the continuous improvement of living standards, people are paying more and more attention to their own health. Therefore, on weekdays, people will do various sports to strengthen their bodies and maintain a healthy mind and body. The sports and exercise items are very diverse, including the popular square dance, the long-standing running, skipping, badminton and other sports with a relatively high popularity rate, and the new items such as yoga, abdominal wheel, body stretching and stretching that have only emerged in recent years, and even simple exercises such as massage sticks suitable for the elderly.
[0003] In these sports and exercises, such as yoga or warm-up exercises, or leg or arm strength training, you often need to use elastic ropes and elastic bands to stretch and unwind. However, ordinary elastic bands are generally made of rubber material in one piece, and their disadvantage is that they cannot adjust the resistance and cannot be used for different resistance requirements, that is, different user groups.
[0004] There are also some elastic bands that are not integrally formed, but have handles connected to both ends. However, the handles and the elastic bands are generally fixedly connected and cannot be removed. Even if the elastic bands and handles are not fixedly connected, they are fixed by screwing screws into the threaded position. If you want to remove them, you must use external tools such as screwdrivers to remove them, which is very troublesome and inconvenient.
[0005] In addition to the inconvenience of adjusting the resistance of the elastic band, there is another common problem with the existing elastic bands, that is, the handle part cannot be adjusted. Because everyone's hands are different in size, especially between men and women or between adults and children, the size difference is quite obvious, so handles of different sizes are needed to adapt. In addition, because the handles sometimes need to be put on the feet, and the hands hold the other end of the elastic band to exercise the legs. Ordinary handles are generally difficult to put on the feet, and it is common to hook part of the handle with the feet. In this case, there is a risk of loosening. Once loose, under the action of the elastic force of the elastic band, the handle originally hooked on the foot will rebound quickly, and it is easy to cause the risk of hitting the body.
[0006] Therefore, the existing elastic band has many deficiencies and needs to be improved. Utility Model Content
