[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides a technical solution for a rust-proof nut structure:

[0020] according to Figure 1-3 As shown, it includes a nut body 1, and six oil storage chambers 7 are equidistantly provided inside the nut body 1. One side of the six oil storage chambers 7 is provided with micro oil holes 8 connected to the inner wall of the nut body 1, and the other side of the six oil storage chambers 7 is provided with oil filling holes 4, and a sealing block 5 is nested inside the oil filling hole 4.

[0021] Specifically, by opening the oil storage cavity 7 inside the nut body 1, the connection part can be sealed by the penetrated sealing oil, thereby reducing the problem of rust on the connection part.

[0022] according to Figure 1 and Figure 2As shown, a sealing ring is sleeved at the connection between the sealing block 5 and the oil filling hole 4, thereby improving the sealing performance of the connection.

[0023] The two sealing gaskets 2 are in the shape of a regular hexagon, and the size of the two sealing gaskets 2 is larger than the size of the end surface of the nut body 1 , so that the shape and size of the sealing gaskets 2 are ensured.

[0024] The number of the stress holes 3 is six groups, and the stress holes 3 located at the bottom are aligned with the stress holes 3 located at the top.

[0025] Specifically, by providing the stress hole 3 , the nut body 1 and the connection portion can be fixed in a limited position, thereby improving the firmness of the connection portion of the nut body 1 .

[0026] The surface of the nut body 1 is plated with a zinc-plated surface layer 6 .

[0027] Specifically, by providing the galvanized surface layer 6 , the anti-corrosion and anti-rust properties of the nut body 1 are effectively improved.

[0028] The inner wall of the nut body 1 is provided with an anti-loosening nylon sleeve 9. Specifically, the anti-loosening nylon sleeve 9 increases the anti-loosening effect of the connection between the nut body 1 and the bolt, and can be widely used in connection under a vibration environment.

[0029] Sealing gaskets 2 are fixedly provided on both sides of the nut body 1, and a plurality of stress holes 3 are equidistantly provided on the surface of the sealing gasket 2. Specifically, the sealing performance of the connection between the nut body 1 and the bolt is increased by the provision of the sealing gasket 2, without the need for a gasket set at the traditional connection.

[0030] Working principle: The utility model is a rust-proof nut structure. When using the high-strength galvanized nut, firstly, the nut body 1 is threadedly connected with the matching bolt, and then the stress hole 3 opened on the surface of the sealing gasket 2 is fixed to the connecting part by pins, thereby improving the firmness of the connecting part. During the use of the nut body 1, the sealing block 5 can be manually pulled out, and sealing oil can be injected into the oil storage cavity 7. The sealing oil flows into the connecting part through the micro oil hole 8, which can not only seal the connecting part, but also reduce the rust of the connecting part, which affects the rotation of the nut body 1 in the later stage.
