[0017] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0018] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0019] like Figures 1 to 4As shown, a proximity switch protection mechanism comprises a mounting plate 1, on which a mounting hole for the proximity switch to pass through is provided, the mounting hole is a long hole arranged in the vertical direction, and a pair of limit nuts 2 located at the front and rear sides of the mounting plate are threadedly connected to the proximity switch; the rear end of the proximity switch is connected to an aviation connector 3, and the rear end of the aviation connector is connected to a cable 4, the cable is covered with a corrugated tube A5, and the aviation connector is covered with a corrugated tube B6, and the rear end of the corrugated tube B extends backward and covers the front end of the corrugated tube A. The proximity switch protection mechanism of the utility model covers the corrugated tube B between the corrugated tube A and the aviation connector, which can effectively protect the connection part of the cable and the aviation connector. At the same time, because the corrugated tube B can effectively fix or pull the front end of the corrugated tube A, the distance between the front end of the corrugated tube A and the aviation connector can be prevented from being further increased.

[0020] In this embodiment, in order to effectively protect the proximity switch and avoid interference from other objects, a protective cover 7 is provided above the proximity switch.

[0021] In this embodiment, the bottom of the protective cover 7 is open, and the left and right sides of the protective cover are provided with vertical slots 8 that can be stuck on the mounting plate, and the front and rear sides of the protective cover are provided with U-shaped slots 9 with an opening facing downward and a width greater than the outer diameter of the proximity switch. When disassembling the proximity switch, you only need to pull the protective cover upward to remove it; the rear end of the proximity switch passes through the U-shaped slot 9 on the rear side, and the front end of the proximity switch is hidden in the protective cover 7. When the object to be measured is too close, it will first touch the front side of the protective cover, which can prevent the object to be measured from directly contacting the proximity switch.

[0022] In this embodiment, the bellows B, the bellows A and the aviation joint are tightly fitted. In order to make the connection more secure, the bellows A and the bellows B are wrapped with tape. In the specific implementation process, the bellows B and the aviation joint can also be wrapped with tape.

[0023] In this embodiment, the mounting plate is welded to a bottom plate and the mounting plate is perpendicular to the bottom plate 10 .

[0024] Unless otherwise stated, any technical solution disclosed in the above utility model, if it discloses a numerical range, then the disclosed numerical range is a preferred numerical range. Any technician in the field should understand that the preferred numerical range is only a numerical value with a more obvious technical effect or representative value among many feasible numerical values. Since there are too many numerical values ​​to be exhaustive, the utility model discloses only some numerical values ​​to illustrate the technical solution of the utility model, and the numerical values ​​listed above should not constitute a limitation on the scope of protection of the utility model.

[0025] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except when it is obviously impossible to use an one-piece molding process).

[0026] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0027] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.

[0028] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
