Abstract

An electric treadmill with a folding mechanism includes a handrail frame pivotably mounted at both sides of the front end of the base frame. A guide plate having a sliding groove, two link plates, and a positioning plate attached to the handrail frame are provided between both sides of the base frame and the handrail frame. The guide plate is connected to a sliding support of a ground-touching roller. The sliding support is pivotably coupled to the bottom of the base frame. According to the assembly of the above-mentioned components, when the base frame is lifted in a folded position, a slide pin of the link plates is movable in the sliding groove of the guide plate until the base frame is folded in an upright position.
