Linkage rod type monolever operating mechanism

The utility model relates to a connecting-rod type single-handle operating mechanism. In the structure of the mechanism, a middle baffle is clamped on two sides of an installation frame through a fixing frame; an operating shaft is divided into the front section, the middle section and the rear section; a location turntable is provided with an axle pin groove, and a circular arc-shaped groove for spacing the working location; the outside diameter is provided with a spacing bulge; the outside diameter of the location turntable is also provided with a rotary slide groove; a hanging pin of the connecting rod is sleeved in the plane hole of the rotary slide groove and is arranged on the middle baffle through a fulcrum positioning pin of the connecting rod; the connecting rod has a sliding long groove and is connected with a rack dialing plate; the lower end of the rack dialing plate is arranged in a rectangular dialing groove of the drive rack; a gear is arranged between the drive rack and the driven rack; the horizontal movement of the drive rack and the driven rack can lock locking tongues in locking grooves that are arranged on two sides of the cabinet. The mechanism has the advantages of simplification of operating procedures, accurate positioning of the handle installation holes of functional units, simple structure, no gear transmission of the original mechanism, and reduction of production cost. So the mechanism can completely replace the large interlocking mechanism of the original MNS type low-voltage power distribution cabinet.
