The primary function of nuts is to provide a mechanical connection and ensure the stability between components through friction.

[0003] Existing rust-proof structures for automotive nuts typically involve applying a rust-proof coating around the nut to prevent rust. However, over time, this coating wears off, resulting in the loss of rust protection, reduced lifespan, and eventual nut detachment. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-rust nut for automobiles to solve the above problems. By wrapping the anti-rust nut with the upper and lower anti-rust mechanisms, the contact area between the anti-rust nut and the outside air is reduced, thereby reducing rusting and extending service life.

[0009] Furthermore, limiting grooves are formed around the upper ring, and the limiting grooves extend upward around the upper ring and penetrate the upper ring.

[0010] Furthermore, the fixing mechanism includes a fixing ring and a limiting sealing ring, the inner wall of the fixing ring is fixedly provided with a threaded groove, and the bottom surface of the fixing ring is provided with a placement groove.

[0011] Furthermore, a limiting plate is slidably arranged around the fixed ring, and a first threaded hole is opened on the top side of each of the four limiting plates. A limiting plate is fixedly arranged on opposite sides of each pair of the four limiting plates.

[0012] Furthermore, a threaded strip is fixedly provided on the outer side of the limiting sealing ring, a second threaded hole is provided on all four sides of the top side of the limiting sealing ring, and a sealing groove is provided on all four sides of the top side of the limiting sealing ring.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] See Figures 1-4 As shown, this utility model provides an anti-rust nut for automobiles, including: an anti-rust screw 1, a lower anti-rust mechanism 2 threaded on the top side of the anti-rust screw 1, an upper anti-rust mechanism 3 snapped onto the top side of the lower anti-rust mechanism 2, a fixing mechanism 4 snapped onto the top side of the upper anti-rust mechanism 3, the anti-rust screw 1 including an anti-rust bolt 101, an anti-rust nut 102 fixedly disposed on the top side of the anti-rust bolt 101, and the anti-rust nut 102 disposed on the inner side between the lower anti-rust mechanism 2 and the upper anti-rust mechanism 3;

[0031] By adopting the above technical solution, the rust-proof screw 1 is wrapped by the lower rust-proof mechanism 2 and the upper rust-proof mechanism 3, which isolates the contact area between the rust-proof screw 1 and the outside air, thereby enabling the rust-proof screw 1 to achieve the function of rust prevention. The rust-proof nut 102 is set between the upper rust-proof mechanism 3 and the lower rust-proof mechanism 2 to avoid excessive contact area between the nut and the air, which would cause corrosion.

[0032] See Figure 1 and5 as well as Figure 8 As shown, the lower rust prevention mechanism 2 includes a lower wrapping ring 201. A connection sealing ring 205 is fixedly provided on the bottom side of the lower wrapping ring 201. A snap-fit ​​rod 203 is fixedly provided on all four sides of the inner bottom surface of the lower wrapping ring 201. A through groove 204 is provided on the top side of each of the four snap-fit ​​rods 203. A bolt through hole 202 is provided in the middle of the inner bottom surface of the lower wrapping ring 201. The bolt through hole 202 extends downward to the connection sealing ring 205.

[0033] In use, the lower ring 201 supports the four snap-fit ​​rods 203 and the sealing ring 205 at the connection. The sealing ring 205 at the connection extends the distance between the nut and the air, further improving the anti-corrosion effect. The four snap-fit ​​rods 203 and the upper anti-rust mechanism 3 are connected by a snap-fit ​​for fixation. The through groove 204 opened on the top side of the snap-fit ​​rod 203 is used to cooperate with the fixing mechanism 4 to fix the upper anti-rust mechanism 3 between the lower anti-rust mechanism 2 and the fixing mechanism 4.

[0034] See Figure 8 As shown, the upper anti-rust mechanism 3 includes an upper wrapping ring 301, a sealing layer 302 is fixedly provided on the inner side of the upper wrapping ring 301, and a limiting groove 303 is provided around the upper wrapping ring 301. The limiting groove 303 extends upward around the upper wrapping ring 301 and penetrates the upper wrapping ring 301.

[0035] In the above embodiment, the upper part of the anti-rust nut 102 is wrapped by the upper wrapping ring 301, the sealing effect of the outer side of the anti-rust nut 102 is improved by the sealing layer 302, and the upper anti-rust mechanism 3 and the lower anti-rust mechanism 2 are connected together by a through snap-fit ​​formed between the limiting groove 303 and the snap-fit ​​rod 203.

[0036] See Figures 4-7 As shown, the fixing mechanism 4 includes a fixing ring 401 and a limiting sealing ring 407. A threaded groove 402 is fixedly provided on the inner wall of the fixing ring 401. A placement groove 405 is opened on the inner bottom surface of the fixing ring 401. Limiting plates 403 are slidably arranged around the fixing ring 401. Each of the four limiting plates 403 has a first threaded hole 404 on its top side. Limiting plates 406 are fixedly provided on opposite sides of each pair of the four limiting plates 403. A limiting sealing ring 407 is fixedly provided on its outer side. A threaded strip 408 is provided. The top side of the limiting sealing ring 407 is provided with second threaded holes 410. The top side of the limiting sealing ring 407 is provided with sealing grooves 409. Sealing limiting bolts 411 are threadedly fitted inside the four second threaded holes 410. Nuts on the top side of the four sealing limiting bolts 411 are snapped into the sealing grooves 409. The limiting plate 406 is made of corrosion-resistant rubber. The four limiting plates 403 slide through the four through grooves 204 respectively.

[0037] In use, the threaded groove 402 on the inner side of the fixing ring 401 engages with the threaded strip 408 on the outer side of the limiting sealing ring 407, allowing the limiting sealing ring 407 to be threadedly fitted inside the fixing ring 401. A certain amount of desiccant and anti-corrosion agent can be placed inside the fixing mechanism 4 via the placement groove 405 to prevent corrosion inside. Four limiting plates 403 pass through the through-grooves 204 on the top side of the locking plate that penetrates the limiting groove 303, and simultaneously penetrate into the inner side of the fixing ring 401, connecting the lower anti-rust mechanism 2 and the upper anti-rust mechanism. 3 is connected to the fixing mechanism 4. At this time, the limiting sealing ring 407 contacts the threaded groove 402 on the inner side of the fixing ring 401 through the outer threaded strip 408, so that the limiting sealing ring 407 is snapped into the inner side of the fixing ring 401, and the second threaded hole 410 and the first threaded hole 404 are connected, so that the four sealing limiting bolts 411 can be sleeved in the two threaded holes to complete the fixing of the limiting plate 403. At the same time, the sealing groove 409 covers the nut of the sealing limiting bolt 411 to reduce the contact between the sealing limiting bolt 411 and the air and prevent rust.

[0038] Using the above structure, when using this product, firstly, the lower anti-rust mechanism 2 passes through the anti-rust screw 1, and then the anti-rust screw 1 is fixed in a suitable position on the car. After fixing, the four limiting grooves 303 of the upper rust-preventing mechanism 3 that are fixed to the upper ring 301 correspond to the four locking rods 203 fixed to the inner bottom surface of the lower ring 201 and are locked together. At this time, the locking rods 203 pass through the limiting grooves 303 and protrude outward, exposing the through groove 204. Then, the four limiting locking plates 403 pass through the through grooves 204 and the fixing ring 401. At this time, the workers can add some corrosion inhibitor to the placement groove 405. Alternatively, a desiccant can be used to ensure the dryness of the inside of the placement slot 405. Then, the limiting sealing ring 407 can be threaded onto the inside of the fixing ring 401. At this time, the limiting sealing ring 407 is located on the top side of the four limiting plates 403, and the second threaded hole 410 in the limiting sealing ring 407 and the first threaded hole 404 in the limiting plate 403 are connected. Finally, the operator inserts the four sealing limiting bolts 411 through the second threaded hole 410 and into the first threaded hole 404. The sealing groove 409 completely wraps the sealing limiting bolts 411, isolating them from contact with the air, thus completing the installation of this product.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
