Patent attributes
A treadmill belt lubricating device for an electric treadmill comprises a transversal axle rod disposed at a frame of the treadmill, and a swinging lever longitudinally coupled to the axle rod, wherein an end of the lever includes an inertia weight, and the other end of the lever is coupled to a transversal U-shape retaining groove, and the retaining groove includes a wool felt, and a lubricant is filled into the wool felt, such that after the foregoing components are assembled, a roller is positioned precisely under the running board, and another end of the wool felt maintains a gap with the treadmill belt, and if the running board is vibrated, then the inertia swing of the lever weight drives the wool felt to be in contact with the bottom surface of the treadmill belt, so as to achieve the effect of constantly lubricating the treadmill belt.
