Abstract

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.

Claims

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

2. The treadmill belt lubricating device for an electric treadmill of claim 1, further comprising an oil filling pipe wrapped by said wool felt, and a plurality of oil outlets penetrated into said oil filling pipe, such that said oil filling hole of said oil filling pipe is disposed at an appropriate position on an external side of said retaining groove.

3. The treadmill belt lubricating device for an electric treadmill of claim 2, further comprising a soft pad disposed at an appropriate position between said lever and said running board.

4. The treadmill belt lubricating device for an electric treadmill of claim 1, further comprising a resilient member installed between said lever and said frame.
