Background technique

Nowadays, long-term computer work is bound to affect people's health. This effect is cumulative and increasingly serious. Inadvertent and laissez-faire attitudes will lead to malignant changes in body functions in the future. Practicing sit-ups can exercise abdominal muscles and relieve The waist is tired, so the sit-up training device is more and more popular among people. The current sit-up training device is mostly an integrated plate structure. With the arbitrarily changing requirements of trainers, people who are new to sit-ups cannot adapt to the current training device. If people are tired from training, the current sit-up training device cannot provide people with a boost when they get up. , people who just come into contact with it are difficult to practice and are unwilling to contact this sport, so we propose a sit-up training device with adjustable angle.

In the Chinese utility model patent document with the publication number CN208160910U, a sit-up training device with an adjustable angle is disclosed. By rotating the handle, the device can make the rack slide up and down in the second cavity so that the upper side of the rack can The teeth of the gear are engaged or disengaged from the gear. When the gear is disengaged from the rack, the pulley can slide back and forth inside the first cavity, and the first spring will make the pulley slide backward, so that the turning plate turns upward. When the trainer uses this When installed, the rotating plate will give the trainer a power boost when getting up, turn the rotating handle to mesh the rack and the gear, the tooth wall and the rack can fix the gear at any position in the first cavity, so as to change the position of the rotating plate and the gear. The angle of the seat cushion, so that trainers of different levels can adjust the angle of the rotating board to a suitable position according to their own needs, but the adjustment process of this device is too troublesome, and after the exercise, the waist muscles of the person will be sore and swollen , massage is needed to eliminate muscle fatigue, and this device cannot massage people's waist.
