[0024] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail by combining with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0025] Referring to Figures 1-3 A waterproof nut 100 is provided by the utility model, which is used for installing a reinforcing plate 300 in a sheet metal box 200. The sheet metal box 200 is provided with an opening for the waterproof nut 100 to pass through. The waterproof nut 100 comprises a body 10, a hex head 20 arranged at the end of the body 10, an external connecting structure arranged on the outer edge surface of the body 10, and an internal connecting structure arranged in the body 10. A relief structure is arranged on one side of the body 10 close to the hex head 20 for the sheet metal box 200 to extrude. A first locking member is locked and fixed on the body 10 through the external connecting structure to fix the reinforcing plate 300 on the sheet metal box 200. The waterproof nut 100 is pressed into the opening of the sheet metal box 200, and the relief structure of the sheet metal box 200 is extruded into the relief structure, which can effectively ensure the stability of the waterproof nut 100 installed in the sheet metal box 200. The external connecting structure of the body 10 is passed into the sheet metal box 200, and then the reinforcing plate 300 is passed through the external connecting structure and locked on the external connecting structure by using a nut and other first locking members, so that the reinforcing plate 300 is fixedly connected in the sheet metal box 200. Therefore, the air tightness is effectively ensured, the shell stress intensity of the sheet metal box 200 is improved, the waterproof glue aging is effectively avoided, the failure caused by the aging of the waterproof glue is avoided, and the air leakage caused by the poor waterproof glue is avoided.

[0026] As Figure 1 and Figure 2As shown, in the embodiment provided by this utility model, the external connection structure is an external thread 30, through which the reinforcing plate 300 passes. A first locking member is threadedly connected to the external thread 30, thereby securing the reinforcing plate 300 within the sheet metal box 200. After the hexagonal head 20 of the waterproof nut 100 is press-riveted into the opening of the sheet metal box 200, the external thread 30 extends into the sheet metal box 200. The reinforcing plate 300 is then passed through the external thread 30 of the waterproof nut 100 and secured to the external thread 30 using a first locking member, such as a nut, thereby securing the reinforcing plate 300 within the sheet metal box 200 and effectively ensuring its stability within the sheet metal box 200. Furthermore, the reinforcing plate 300 is provided with multiple through-holes through which the external thread 30 passes. The reinforcing plate 300 is mounted within the sheet metal box 200 via multiple waterproof nuts 100. By passing multiple waterproof nuts 100 through the through holes on the reinforcing plate 300 and using multiple nuts or other first locking members to lock the external threads 30 of the waterproof nuts 100, the reinforcing plate 300 is fixed in the sheet metal box 200, which can further improve the stability of the reinforcing plate 300 fixed in the sheet metal box 200, thereby stably improving the stress strength of the outer shell of the sheet metal box 200, and avoiding aging of the waterproof glue, resulting in failure, and the occurrence of air leakage due to poor application of the waterproof glue.

[0027] like Figure 1 and Figure 3 As shown, in the embodiment provided by the present invention, the back-off structure is a back-off groove 50. After the hexagonal head 20 is pressed into the opening of the sheet metal box 200 by riveting, the bulged material of the sheet metal box 200 is squeezed into the back-off groove 50. By pressing the hexagonal head 20 into the opening of the sheet metal box 200 by riveting, the bulged material of the sheet metal box 200 is squeezed into the back-off groove 50. This can effectively ensure the stability of the waterproof nut 100 installed in the opening of the sheet metal box 200 by riveting, thereby effectively preventing the waterproof nut 100 from falling out of the opening of the sheet metal box 200. This further ensures the stability of the reinforcing plate 300 passing through the external thread 30 of the waterproof nut 100 and locking the reinforcing plate 300 in the sheet metal box 200 using a first locking member such as a nut. In addition, after the hexagonal head 20 is pressed into the opening of the sheet metal box 200 by riveting, the outer end surface of the hexagonal head 20 is flush with the outer end surface of the sheet metal box 200, thereby effectively ensuring the stability of the waterproof nut 100 installed on the sheet metal box 200, while further improving the overall aesthetics of the sheet metal box 200 using the waterproof nut 100, and avoiding the hexagonal head 20 being exposed outside the sheet metal box 200, affecting the visual beauty.

[0028] like Figure 1 and Figure 2As shown in the embodiment provided by the utility model, the limiting table 60 for limiting the locking position of the first locking member is arranged between the tool withdrawal groove 50 and the external thread 30. The limiting table 60 arranged between the tool withdrawal groove 50 and the external thread 30 can effectively limit the position of the nut or other first locking member locked on the external thread 30 of the waterproof nut 100, and the limiting table 60 can also effectively limit the installation position of the reinforcing plate 300 on the external thread 30 of the waterproof nut 100. In addition, the elastic pad is arranged between the first locking member and the limiting table 60. The stability of the reinforcing plate 300 locked and fixed in the metal box body 200 by the nut or other first locking member can be effectively ensured, the stress strength of the shell of the metal box body 200 is improved, and the air tightness of the waterproof nut 100 and the reinforcing plate 300 installed in the metal box body 200 is ensured.

[0029] As shown in the embodiment provided by the utility model, the limiting table 60 for limiting the locking position of the first locking member is arranged between the tool withdrawal groove 50 and the external thread 30. The limiting table 60 arranged between the tool withdrawal groove 50 and the external thread 30 can effectively limit the position of the nut or other first locking member locked on the external thread 30 of the waterproof nut 100, and the limiting table 60 can also effectively limit the installation position of the reinforcing plate 300 on the external thread 30 of the waterproof nut 100. In addition, the elastic pad is arranged between the first locking member and the limiting table 60. The stability of the reinforcing plate 300 locked and fixed in the metal box body 200 by the nut or other first locking member can be effectively ensured, the stress strength of the shell of the metal box body 200 is improved, and the air tightness of the waterproof nut 100 and the reinforcing plate 300 installed in the metal box body 200 is ensured. Figure 1 and Figure 2 As shown in the embodiment provided by the utility model, the limiting table 60 for limiting the locking position of the first locking member is arranged between the tool withdrawal groove 50 and the external thread 30. The limiting table 60 arranged between the tool withdrawal groove 50 and the external thread 30 can effectively limit the position of the nut or other first locking member locked on the external thread 30 of the waterproof nut 100, and the limiting table 60 can also effectively limit the installation position of the reinforcing plate 300 on the external thread 30 of the waterproof nut 100. In addition, the elastic pad is arranged between the first locking member and the limiting table 60. The stability of the reinforcing plate 300 locked and fixed in the metal box body 200 by the nut or other first locking member can be effectively ensured, the stress strength of the shell of the metal box body 200 is improved, and the air tightness of the waterproof nut 100 and the reinforcing plate 300 installed in the metal box body 200 is ensured.

[0030] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection range of the utility model.
