Description

Technical Field

[0001] This utility model relates to the field of flange nut technology, and in particular to an anti-slip flange nut. Background Technology

[0002] A flange nut is a type of nut with a wide flange at one end, which can act as an integral washer. This is used to distribute the pressure of the nut across the fastened component, thereby reducing the likelihood of component damage.

[0003] Flange nuts serve to securely fasten components in various fields. However, in harsh environments, such as high-temperature and high-heat environments, the thread surface relies on only a single coating (such as zinc or nickel plating), which is easily damaged by mechanical wear, leading to corrosion and jamming. After corrosion or seal failure, the entire nut needs to be replaced, resulting in a waste of resources. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that in harsh environments, such as high temperature and high heat environments, the thread surface relies on only a single coating (such as zinc plating or nickel plating), which is easily damaged by mechanical wear, leading to corrosion and jamming. After corrosion or seal failure, the entire nut needs to be replaced, resulting in a waste of resources.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an anti-slip flange nut, comprising:

[0006] A square twist head, wherein a flange is provided at the lower end of the square twist head, and the square twist head and the flange are cast as one piece;

[0007] The lower end of the flange is provided with a fluororubber ring, and an annular sealing groove is embedded in the groove.

[0008] The flange has a radial guide groove with a depth of 1-2mm at its lower end, and the bottom of the radial guide groove has an inclination angle of 5-10°. The flange has an injection hole on its side, and an injection groove is provided between the radial guide groove and the injection hole on the side to connect them.

[0009] In a preferred embodiment, the injection hole is provided with a plug made of stainless steel or nylon. The plug can be sealed after the glue is injected to prevent the glue from oxidizing and failing at the injection hole.

[0010] In a preferred embodiment, the internal thread surface of the square twist head is sequentially provided with an electroplated nickel layer and a PTFE composite coating. Through these two layers of corrosion protection, the oxidation and corrosion resistance of the device is effectively improved.

[0011] In a preferred embodiment, the inner side of the annular sealing groove is provided with anti-slip texture to enhance the friction of the fluororubber ring sealing contact surface.

[0012] As a preferred embodiment, the outer edges of the square twist head and flange are rounded, with the rounding angle set between 1mm and 1.5mm. By reasonably setting the rounding, the demolding resistance can be significantly reduced, product damage and mold wear can be reduced, and production efficiency can be improved.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] This invention involves injecting sealant into radial guide grooves through injection holes. After the sealant cures, it forms a sealing ring, which enhances leak prevention and prevents oxygen or liquid from contaminating and corroding the sealing rubber ring through the gap between the flange and the connector. The sealant can also be repeatedly replenished after curing, oxidation, and deformation to extend the seal life. The operation is simple and quick, prevents seal failure, and reduces resource waste caused by disassembly. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: an anti-slip flange nut, comprising:

[0023] A square twist head 1, with a flange 2 at the lower end of the square twist head 1, and the square twist head 1 and the flange 2 are cast as one piece;

[0024] The lower end of the flange 2 is equipped with a fluororubber ring 4, and an annular sealing groove 5 is embedded in the groove to prevent oxidation deformation at the threaded part from causing the connection to loosen.

[0025] The flange 2 has a radial guide groove 7 with a groove depth of 1-2mm at the lower end, and the bottom of the radial guide groove 7 has an inclination angle of 5-10°. The flange 2 has an injection hole 3 on the side end, and an injection groove 6 is provided between the radial guide groove 7 and the side injection hole 3 for communication.

[0026] After tightening the nut, inject sealant such as epoxy resin or silicone into the radial guide groove 7 through the injection hole 3. After curing, the sealant forms a sealing ring, enhancing the leak-proof capability. The sealant flows along the radial guide groove and can fill the gap between the flange 2 and the connecting parts. The sealing ring formed after the sealant cures enhances the leak-proof capability and prevents oxygen or liquid from contaminating and corroding the sealing rubber ring through the gap between the flange 2 and the connecting parts. The sealant can also be repeatedly replenished after the sealant cures, oxidizes, and deforms, extending the seal life. The operation is simple and quick, can prevent seal failure, and reduce the waste of resources caused by disassembly.

[0027] like Figure 1-4 As shown, the injection hole 3 is equipped with a plug. The plug is made of stainless steel or nylon and can be used to seal after the glue is injected to prevent the glue from oxidizing and failing at the injection hole 3.

[0028] like Figure 1-4 As shown, the internal thread surface of the square twist head 1 is sequentially provided with an electroplated nickel layer and a PTFE composite coating. Through the two layers of corrosion protection, the oxidation and corrosion resistance of the device is effectively improved.

[0029] like Figure 1-4 As shown, the inner side of the annular sealing groove 5 is provided with anti-slip texture to enhance the friction of the sealing contact surface of the fluororubber ring 4.

[0030] like Figure 1-4 As shown, the outer edges of the square twist head 1 and the flange 2 are rounded, with the rounding angle set between 1mm and 1.5mm. By properly setting the rounding, the demolding resistance can be significantly reduced, product damage and mold wear can be minimized, and production efficiency can be improved.

[0031] Working principle: After tightening the nut, sealant such as epoxy resin or silicone is injected into the radial guide groove 7 through the injection hole 3. After curing, the sealant forms a sealing ring, enhancing the leak-proof capability. The sealant flows along the radial guide groove and can fill the gap between the flange 2 and the connecting parts. The sealing ring formed after the sealant cures enhances the leak-proof capability and prevents oxygen or liquid from contaminating and corroding the sealing rubber ring through the gap between the flange 2 and the connecting parts. The sealant can also be repeatedly replenished after curing, oxidation and deformation, extending the seal life. The operation is simple and quick, can prevent seal failure, and reduce the waste of resources caused by disassembly.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
