Treadmill with automatic adjustment

The invention relates to a treadmill with automatic adjustment function, which has a running belt adjusting device, which can automatically detect and automatically adjust the deviation of the running belt, and has a belt adjusting device, which can mechanically adjust the tension of the belt and improve the running. The transmission efficiency of the machine, for the professional fitness center with a large number of treadmills, can increase the stability and economic benefits of the treadmill, so it is actually a practical and progressive invention, quite It is worthy of promotion by the industry and publicity to the public.

Modern people are busy, need to exercise in moderation to adjust the pace of life. Treadmills are easy to operate and have good exercise efficiency. They are a common sports equipment, except for some families who buy and use them at home. Others are like gyms attached to restaurants. There are also membership-based fitness centers, and you can also see the settings of the treadmill. The conventional treadmill mainly has a front roller and a rear roller respectively disposed on the front and rear ends of a pallet, and a running belt is arranged on the front and rear rollers, and is matched by an electric motor on the shaft. A belt transmits rotational kinetic energy to the front roller, thereby driving the running belt to circulate around the pallet, so that the user can run on the running belt. However, because the outer circumferential surface of the roller is relatively smooth, the running belt is around the board. When the cycle is moving, it often occurs along the axial direction of the roller. When the edge of the running belt touches the frame provided on the two sides of the plate, it will wear out, which not only shortens the service life of the running belt, but also reduces the running belt. The stability of the cycle around the slab, and even the endangered person for the user who is running The serious impact of safety. In order to solve the problem of running belt offset, some treadmills have been equipped with an anti-offset mechanism to adjust the position of the running belt, but there are a large number of gymnasiums and membership-based fitness centers in the hotel. Treadmills, if you manually adjust the running belts of a large number of treadmills by hand, it is quite a laborious task, and the speed is slow and time-consuming, which is not economical at all. Based on personal experience, it is impossible to ensure that the running belt has been adjusted back and the safety is questioned!

In view of this, the inventors have actively developed research and can create a function that can automatically detect and adjust the treadmill's running belt, making it more practical and economical, so as to improve the manual operation on the market.
