Description

Technical Field

[0001] The utility model mainly relates to the technical field of fitness equipment, and in particular to an intelligent fitness system. Background Art

[0002] With the development of social economy and the improvement of people's living standards, more and more people pay attention to health and participate in fitness. However, urban congestion and fast-paced life increase the time cost of going to the gym.

[0003] At present, there are many kinds of fitness equipment on the market with different functions. Among them, tension fitness is relatively simple, so it has been effectively popularized. However, traditional tension fitness equipment with adjustable tension is very bulky, occupies a large area, and the overall structure of the adjustment device corresponding to the mechanical arm is complex, occupies a large volume, and is complicated to operate, making it very inconvenient for people to exercise.

[0004] The applicant of this patent has previously designed a multifunctional wall-mounted tension fitness system, but it was found that there is still a corresponding problem in the subsequent use process: the life of the pull rope is short. After further analysis, it was found that because the load-bearing pull ropes of the existing intelligent fitness system are all guided by small pulleys, and there are many of them, when the pull rope is slid on the small pulley, because the pull rope needs to be turned through the small pulley, the small angle bending of the small pulley will shorten the life of the pull rope. In addition, when the existing mechanical arm rotates, it will also drive the pull rope to twist, thereby further shortening the life of the pull rope. Utility Model Content
