Abstract
The utility model discloses a special-purpose adjusting device for an engine running stand. The adjusting device comprises a lower adjusting iron pad, an upper adjusting iron pad, an adjusting screw, a first flat nut, a second flat nut and a dual-lug backstop pad. Mutual movement of the upper and lower adjusting iron pads is limited by a groove of the lower adjusting iron pad and a protruding strip of the upper adjusting iron pad, and the lateral shifting amount of the upper and lower adjusting iron pads is controlled within 2mm, so that adjustment is stable and controllability is good. The adjusting screw is connected with the lower adjusting iron pad via a mortise, thereby preventing axial play of the upper adjusting iron pad which is driven by the screw. The upper and lower adjusting iron pads are made of iron pieces, so that rigidity can be enhanced, and the iron pads are not easy to fragile. After completion of adjustment, the first and second flat nuts are locked with the lower adjusting iron pad via the dual-lug backstop pad. Thus, the special-purpose adjusting device for the engine running stand is simple in structure, convenient to operate and smooth in adjustment, and completely effective.
