Description

Technical Field

[0001] The present invention relates to the technical field of treadmill deviation correction, and particularly to a steel pipe reinforcement structure for sports equipment. Background Art

[0002] Treadmills are fitness equipment commonly used in families and gyms. Moreover, they are the simplest type of home fitness equipment and the best choice for home fitness machines. When using a treadmill, due to the influence of the human running motion and the operation of the treadmill itself, the treadmill will generate certain vibrations. The transmission of these vibrations will affect the surrounding environment and damage the fitness environment. Moreover, when the treadmill operates for a long time, due to the influence of the treadmill vibrations, the running belt will deviate, affecting the normal operation of the running belt. Currently, correcting the deviation of the running belt is achieved by manually adjusting the treadmill rollers, which is time-consuming and laborious. Summary of the Invention
