[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1-5As shown, the utility model discloses a waterproof nut 1, including a nut 1, on which a waterproof component is provided, the waterproof component including a sealing sleeve 2 detachably arranged above the nut 1, a sealing ring A3 located below the nut 1, and a sealing ring B4 fixedly arranged below the sealing ring A3, a sealing groove A5 penetrating the inner hole of the nut 1 is provided on the bottom wall of the nut 1, the sealing ring A3 is located inside the sealing groove A5 and is fixedly connected to the nut 1, the sealing ring B4 is located directly below the thread of the nut 1, and the diameter of the sealing ring B4 is smaller than the major diameter of the thread of the nut 1. When assembling the present invention, apply sealant on the top wall and outer wall of the sealing ring A3, put the sealing ring A3 into the sealing groove A5, and fix the sealing ring A3 to the nut 1 through the sealant, so that the connection between the sealing ring A3 and the nut 1 is completely sealed; apply sealant on the top wall of the sealing gasket 6 and the outer wall of the positioning ring 17, insert the positioning ring 17 into the positioning groove 18, and fix the positioning ring 17 to the nut 1 through the sealant, so that the installation position of the sealing gasket 6 is positioned, and then the sealing gasket 6 is inserted into the sealing groove B7 and fixedly connected to the nut 1 through the sealant, so that the connection between the sealing gasket 6 and the nut 1 is completely sealed; place the sealing sleeve 2 above the nut 1, insert the pressure pad 10 into the pressure groove 11, screw the threaded sleeve 8 into the threaded groove 12 and tighten it, so that the pressure ring 9 presses the pressure pad 10 tightly against the inside of the pressure groove 11, so that the sealing sleeve 2 is fixedly connected to the nut 1, and the assembly of the present invention is completed; when using the present invention, pass the screw through the screw to be locked After the nut 1 is tightened, the sealing ring B4 will be pressed against the side wall of the through hole of the part to be locked, thereby playing a sealing role. After the nut 1 is tightened, the sealing gasket 6 will be pressed against the part to be locked by the nut 1, thereby playing a further sealing role. After the nut 1 is tightened, the protruding part of the screw will be located inside the sealing sleeve 2, and the sealing sleeve 2 will cover the protruding part of the screw, preventing external moisture from contacting the screw, thereby preventing the screw thread from rusting. In summary, the utility model has a sealing function and has the beneficial effect of preventing the screw thread from rusting, which solves the problem that the traditional nut 1 usually does not have a waterproof function, and external moisture can easily enter the threaded connection between the nut 1 and the screw, causing the thread to rust.

[0021] Preferably, the waterproof assembly further includes a sealing gasket 6. A sealing groove B7 is defined on the bottom wall of the nut 1. The sealing gasket 6 is located within the sealing groove B7 and is fixedly connected to the nut 1. The width of the sealing groove B7 is greater than the width of the sealing gasket 6. The bottom of the sealing gasket 6 protrudes from the bottom of the nut 1 and is arranged in an arc shape. Since the width of the sealing groove B7 is greater than the width of the sealing gasket 6, the bottom of the sealing gasket 6 protrudes from the bottom of the nut 1 and is arranged in an arc shape. When the sealing gasket 6 is pressed against the part to be locked by the nut 1, the sealing gasket 6 will extend inwards and outwards, thereby filling the sealing groove B7, thereby increasing the sealing area and improving the sealing performance.

[0022] Preferably, the waterproof assembly further comprises a threaded sleeve 8, a pressure ring 9 fixedly arranged on the inner side of the threaded sleeve 8, a pressure pad 10 fixedly arranged below the sealing sleeve 2, a pressure groove 11 and a thread groove 12 are provided on the top wall of the nut 1, the pressure groove 11 is located inside the thread groove 12, the pressure pad 10 is located inside the pressure groove 11, and after the threaded sleeve 8 is screwed into the thread groove 12, the pressure ring 9 is located above the pressure pad 10 and fixedly connected to the pressure pad 10. Since the pressure ring 9 is located above the pressure pad 10 and fixedly connected to the pressure pad 10 after the threaded sleeve 8 is screwed into the thread groove 12, the pressure ring 9 will press the pressure pad 10 tightly inside the pressure groove 11, so that the sealing sleeve 2 is fixedly connected to the nut 1, which facilitates the disassembly and assembly of the sealing sleeve 2; when the protruding part of the screw is long, the threaded sleeve 8 can be screwed out of the thread groove 12, and then the sealing sleeve 2 can be replaced, which plays a role in adapting to screws of different lengths.

[0023] Preferably, the waterproof assembly further comprises an anti-loosening ring 13, a plurality of ratchets 14 fixedly disposed below the anti-loosening ring 13, and a magnetic plate 15 fixedly disposed on the top wall of the anti-loosening ring 13. An anti-loosening groove 16 is provided on the bottom wall of the nut 1, and an iron sheet is fixedly disposed on the top wall of the anti-loosening groove 16. After the anti-loosening ring 13 is inserted into the anti-loosening groove 16, the magnetic plate 15 is magnetically connected to the iron sheet, and the ratchets 14 protrude from the bottom of the nut 1. Since the plurality of ratchets 14 are fixedly disposed below the anti-loosening ring 13, when the nut 1 and the screw are tightened, the ratchets 14 will penetrate into the interior of the part to be locked, thereby preventing the nut 1 from loosening. Since the magnetic plate 15 is magnetically connected to the iron sheet after the anti-loosening ring 13 is inserted into the anti-loosening groove 16, it facilitates the disassembly and assembly of the anti-loosening ring 13. The user can decide whether to use the ratchets 14 based on the surface requirements of the part to be locked.

[0024] Preferably, a positioning ring 17 is fixedly provided above the sealing gasket 6, and a positioning groove 18 is provided on the top wall of the sealing groove B7. After the positioning ring 17 is inserted into the positioning groove 18, the sealing gasket 6 is inserted into the sealing groove B7 and fixedly connected to the nut 1. Since the positioning ring 17 is inserted into the positioning groove 18 and the sealing gasket 6 is inserted into the sealing groove B7 and fixedly connected to the nut 1, the installation position of the sealing gasket 6 is positioned, preventing the installation position of the sealing gasket 6 from shifting, which would make it difficult to extend the seal later.

[0025] Preferably, the sealing sleeve 2, the sealing gasket 6, the sealing ring A3 and the sealing ring B4 are all made of elastic rubber. Since the sealing sleeve 2, the sealing gasket 6, the sealing ring A3 and the sealing ring B4 are all made of elastic rubber, they have the characteristics of good elasticity and good sealing performance.

[0026] Preferably, a plurality of anti-slip strips 19 are fixedly provided on the outside of the threaded sleeve 8. Since a plurality of anti-slip strips 19 are fixedly provided on the outside of the threaded sleeve 8, the threaded sleeve 8 is prevented from slipping when it is rotated.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
