In which like parts are designated by like reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings. The terms "inner" and "outer" are used to refer to directions toward and away from, respectively, the geometric center of a particular component.
As shown in fig. 1-3, the present invention is a fixing structure for an operating mechanism of an automatic transfer switch, which includes a mounting plate 1, wherein the mounting plate 1 is connected to an end surface of a base 4 through a bolt and nut structure, two sides of the base 4 are connected to side covers 5, and a nut limiting structure is arranged between the base 4 and the side covers 5.
As shown in fig. 4, the mounting plate 1 is provided with first coupling through holes 11 for receiving the screws 6. The first connecting through holes 11 are arranged at four corners.
As shown in fig. 5-6, the end surface of the base 4 is provided with a second connecting through hole 43, and the arrangement of the second connecting through hole 43 is matched with the position of the first connecting through hole 11. The first limiting surface 42 of the periphery of the nut and the side cover installation guide groove 41 are arranged on one side of the second connecting through hole 43, and the part around the second connecting through hole 43 is the limiting surface 44 of the end surface of the inner side of the nut. One side of the first limiting surface 42 on the periphery of the nut is provided with a limiting surface 45 on the outer end surface of the nut. The side surface of the base 4 is provided with a side cover mounting guide hole 46 and a side cover riveting hole 47 from outside to inside.
