[0028] Please refer to Figures 1-3 As shown, this embodiment is a three-interface special-shaped locking nut, including:

[0029] A nut assembly, the nut assembly includes a nut body 11;

[0030] A protection assembly, the protection assembly includes a card slot 21, a lower gasket 22, an upper gasket 23, a bottom plate 24, a top plate 25, a fixed column 26, and a fixed nut 27. The card slot 21 is located on both sides of the nut body 11. The lower gasket 22 and the upper gasket 23 are clamped inside the card slot 21. The bottom plate 24 is placed inside the lower end of the lower gasket 22. The top plate 25 is placed inside the upper end of the upper gasket 23. The fixed column 26 is fixedly connected to the central position of the upper end of the bottom plate 24. The fixed nut 27 is threadedly connected to the outer surface of the fixed column 26;

[0031] The card slot 21 is used to fix the lower gasket 22 and the upper gasket 23. The lower gasket 22 and the upper gasket 23 are used to seal the outer ends on both sides of the threaded interface 12. The bottom plate 24 is used to limit the lower gasket 22. The top plate 25 is used to limit the upper gasket 23. The fixing column 26 is used to support the bottom plate 24 and the top plate 25. The fixing nut 27 is used to limit the top plate 25.

[0032] The nut assembly further includes a threaded interface 12 which is opened at an internal position of the nut body 11;

[0033] The threaded interface 12 is used to fix a bolt.

[0034] The outer surface of the fixing column 26 has a threaded structure opened relative to the fixing nut 27, and the fixing nut 27 is located at an outer position of the top plate 25;

[0035] The fixing nut 27 can move up and down along the fixing column 26. When the bottom end of the fixing nut 27 contacts the top end of the top plate 25, the top plate 25 can be limited.

[0036] The fixing column 26 extends outward through the threaded interface 12, and the upper end of the lower gasket 22 and the lower end of the upper gasket 23 are respectively attached to both sides of the nut body 11;

[0037] The lower gasket 22 and the upper gasket 23 are limited by the bottom plate 24 and the top plate 25 on both sides of the nut body 11.

[0038] Working principle: When it is necessary to seal the inside of the threaded interface 12, the lower gasket 22 and the upper gasket 23 are clamped inside the card slot 21, the bottom plate 24 is placed inside the lower end of the lower gasket 22, at the same time, the fixing column 26 extends upward through the threaded interface 12, then the top plate 25 is sleeved on the outer surface of the fixing column 26, and the top plate 25 is placed inside the upper end of the upper gasket 23. At this time, by rotating the fixing nut 27, the fixing nut 27 moves downward driven by the threaded structure. When the bottom end of the fixing nut 27 contacts the top end of the top plate 25, the fixing nut 27 can fix the bottom plate 24 and the top plate 25 at the outer positions of the lower gasket 22 and the upper gasket 23, and fix the lower gasket 22 and the upper gasket 23 on both sides of the nut body 11, so that the bottom plate 24, the lower gasket 22, the top plate 25 and the upper gasket 23 close both sides of the threaded interface 12; When it is necessary to use the threaded interface 12, just operate the above steps in reverse.

[0039] Please refer to Figure 4 As shown, based on the above embodiment, this embodiment further includes:

[0040] The limiting component includes a movable disc 31, a movable column 32, a baffle 33 and a telescopic spring 34. The movable disc 31 is slidably connected to both sides inside the nut body 11. The movable column 32 is fixedly connected to the top of the movable disc 31. The baffle 33 is fixedly connected to the top of the movable column 32. The telescopic spring 34 is fixedly connected to the outer side of the top of the movable disc 31.

[0041] The movable disc 31 is used to limit the movable column 32. The movable column 32 is used to support the baffle 33. The baffle 33 is used to block the outside of the threaded interface 12. The telescopic spring 34 is used to drive the baffle 33 to reset.

[0042] The other end of the telescopic spring 34 is fixedly connected to the upper end inside the nut body 11, and the telescopic spring 34 surrounds the outer surface of the lower end of the movable column 32.

[0043] When the movable column 32 moves outwards, the movable column 32 can drive the movable disc 31 to move outwards, and the movable disc 31 drives the telescopic spring 34 to be compressed.

[0044] Working principle: When it is necessary to limit the bolt inside the threaded interface 12, by applying an outward force to the baffle 33, the baffle 33 moves outwards. The baffle 33 moving outwards drives the movable column 32 and the movable disc 31 to move outwards. The movable disc 31 moving outwards drives the telescopic spring 34 to be compressed to generate an elastic force. When the bottom end of the baffle 33 is separated from the nut body 11, apply a rotational force to the baffle 33 so that the baffle 33 does not block the outside of the threaded interface 12. Then place the bolt inside the threaded interface 12 and rotate the baffle 33 in the reverse direction so that the baffle 33 is located at the outer end of the bolt. At this time, if the bolt becomes loose, the baffle 33 blocks the outside of the bolt, thus preventing the bolt from falling off.
