Wherein 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 words "inner" and "outer" are used to refer to directions toward or away from, respectively, the geometric center of a particular component.
As shown in fig. 1-3, the invention relates to a fixing structure of an automatic change-over switch operating mechanism, which comprises a mounting plate 1, wherein the mounting plate 1 is connected with the end surface of a base 4 through a bolt and nut structure, two sides of the base 4 are connected with 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 a first connection through hole 11 for receiving the screw 6. The first connecting holes 11 are arranged in four corners.
As shown in fig. 5 to 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 adapted to the position of the first connecting through hole 11. The first limiting surface 42 of the outer 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 limiting surface 44 of the inner end surface of the nut is arranged on the periphery of the second connecting through hole 43. The first limit surface 42 of the outer periphery of the nut is provided with a limit surface 45 of the outer end surface of the nut. The side surface of the base 4 is provided with a side cover installation guide hole 46 and a side cover riveting hole 47 from outside to inside.
As shown in fig. 7, a side cover mounting guide block 51 is provided on the side cover 5, and a second limit surface 52 on the outer periphery of the nut is provided on the side cover mounting guide block 51. A side cover mounting guide post 53 is arranged on one side of the side cover mounting guide block 51, and a riveting through hole 54 is formed in the side cover mounting guide post 53.
In order to prevent the base 4 from being turned upside down during the mounting process, an error proofing mechanism is provided between the mounting plate 1 and the base 4.
The error preventing mechanism comprises error preventing holes 12 and error preventing bosses 48, wherein the error preventing holes 12 are positioned on the mounting plate 1 and are unevenly distributed in a way of being fewer in the upper part and more in the lower part, and when the error preventing holes are not mounted according to the specification, the error preventing bosses 48 cannot be embedded into the error preventing holes 12. The error-proof boss 48 is located on the end face of the base 4 and is matched with the position of the error-proof hole 12.
The working process of the invention is as follows:
firstly, the side surface of the nut 3 is pushed into the base 4 from the side cover installation guide groove 41, two end surfaces of a threaded hole of the nut 3 are positioned between the inner end surface limiting surface 44 of the nut and the outer end surface limiting surface 45 of the nut, and the inner end surface limiting surface 44 of the nut and the outer end surface limiting surface 45 of the nut limit the axial movement of the nut 3.
Next, the side cover mounting guide block 51 on the side cover 5 is inserted into the side cover mounting guide groove 41, and simultaneously the side cover mounting guide post 53 is inserted into the side cover mounting guide hole 46, and the nut outer periphery second limit surface 52 pushes the nut 3 to move until abutting against the nut outer periphery first limit surface 42. The nut outer peripheral second limiting surface 52 and the nut outer peripheral first limiting surface 42 limit the rotation of the nut 3.
The rivet 2 sequentially passes through the rivet through hole 54 and the side cover rivet hole 47 to rivet the side cover 5 and the base 4 together.
The screw 6 passes through the first connecting through hole 11 of the mounting plate 1 and then passes through the second connecting through hole 43 of the base 4, and can be in threaded connection with the nut 3. The base 4 is thus securely mounted on the mounting plate 1. The screw 6 is operated on the back of the mounting plate 1, thereby effectively preventing misoperation and reducing the external deformation of the base 4 caused by screw fixation.
In this embodiment, the outer periphery of the nut 3 is hexagonal, and the second limiting surface 52 of the outer periphery of the nut and the first limiting surface 42 of the outer periphery of the nut are 120 ° folded structures, and are disposed on the outer periphery of the nut 3.
In other embodiments, the outer periphery of the nut 3 may have a square, oval or other shape.
The above embodiments are provided to illustrate the technical concept and features of the present invention and are intended to enable those skilled in the art to understand the content of the present invention and implement the same, and are not intended to limit the scope of the present invention. All equivalent changes or modifications made in accordance with the spirit of the present invention should be construed to be included in the scope of the present invention.
