[0002] A nut is a common fastener that is often used to connect two or more objects together. It consists of a hole with an internal thread and a matching external shape. Nuts are often used with bolts to tighten the connection by inserting the bolt into the hole of the nut and turning the nut.

[0003] By tightening the nut, the connected parts can be tightly combined and not easy to loosen. This tightening performance enables the nut to perform well in environments that need to withstand heavy loads and vibrations, and can ensure the stability and safety of the equipment; once the nut is tightened, it can be used repeatedly without frequent replacement. This reusability not only reduces maintenance costs, but also reduces resource waste, which is in line with the concept of sustainable development; the nut can be installed and removed with a simple rotating action, without the need for complex tools and techniques. This easy-to-install feature makes the nut very convenient for quick repair and replacement of parts, improving work efficiency; the nut can also be used with bolts of various shapes and sizes to meet different connection requirements. Whether in bridge construction, mechanical equipment or electronic products, nuts can play an important role and demonstrate their strong adaptability.

[0031] See also Figure 1-3 As shown, this embodiment provides a heat-resistant and corrosion-resistant nut, comprising:

[0032] The nut body 100 .

[0033] The cold-resistant layer 110 , the reinforcement layer 120 and the heat-resistant layer 130 are arranged on the outer surface of the nut body 100 from inside to outside.

[0034] The protective shell 140 includes a first protective shell 141 and a second protective shell 142 for constituting the protective shell 140 . Both ends of the first protective shell 141 have buckles 1411 , and both ends of the second protective shell 142 have slots 1421 matching the buckles 1411 .

[0035] The protective cover 160 is sleeved on the outer surface of the protective shell 140 .

[0036] It can be seen that the heat-resistant corrosion nut provided in this embodiment has a cold-resistant layer 110, a reinforcement layer 120 and a heat-resistant layer 130, and the cold-resistant layer 110, the reinforcement layer 120 and the heat-resistant layer 130 are arranged from the inside to the outside on the outer surface of the nut body 100, which can enable the nut to maintain stable performance in a variety of environments. The cold-resistant layer 110 can prevent the nut from becoming brittle or cracking in a low-temperature environment; the reinforcement layer 120 can improve the mechanical strength of the nut, making it have better tensile, compressive and impact resistance; and the heat-resistant layer 130 can protect the nut from being damaged in a high-temperature environment.

[0037] Furthermore, the present embodiment also provides a protective shell 140, including a first protective shell 141 and a second protective shell 142, and the protective shell 140 effectively protects the nut body 100 from being invaded by the external environment; both ends of the first protective shell 141 have buckles 1411, and both ends of the second protective shell 142 have slots 1421 matching the buckles 1411, so that the first protective shell 141 and the second protective shell 142 can be tightly combined together to form a complete protective shell 140; the protective cover 160 is sleeved on the outer surface of the protective shell 140 to further enhance the protection ability of the protective shell 140 and prevent the external environment from further eroding the nut.

[0038] It can be understood that the heat-resistant corrosion nut provided in this embodiment has excellent environmental adaptability, mechanical strength and protection ability, and can be widely used in various occasions that need to withstand high temperature, low temperature or corrosive environment.

[0039] Specifically, the thickness of the cold-resistant layer 110 is smaller than the thickness of the reinforcement layer 120 .

[0040] It can be understood that the thickness of the cold-resistant layer 110 is smaller than the thickness of the reinforcement layer 120, which can ensure that the nut has sufficient cold resistance in a low temperature environment, while not affecting the mechanical strength of the nut due to the excessive thickness of the cold-resistant layer 110; the relatively thick reinforcement layer 120 can also improve the mechanical strength and load-bearing capacity of the nut.

[0041] Specifically, the thickness of the heat-resistant layer 130 is smaller than the thickness of the reinforcement layer 120 .

[0042] It can be understood that the thickness of the heat-resistant layer 130 is less than the thickness of the reinforcement layer 120, which can ensure that the nut has sufficient heat resistance in a high temperature environment, and at the same time will not affect the mechanical strength of the nut due to the excessive thickness of the heat-resistant layer 130; the reinforcement layer 120 is relatively thick and can also improve the mechanical strength and load-bearing capacity of the nut; the heat-resistant layer 130 is relatively thin and can also reduce the thermal expansion of the nut in a high temperature environment, preventing the nut from losing its original precision and stability due to thermal expansion.

[0043] Specifically, an anti-slip texture layer 150 is disposed between the protective shell 140 and the protective cover 160 .

[0044] It can be understood that providing an anti-slip texture layer 150 between the protective shell 140 and the protective cover 160 can effectively increase the friction between the protective shell 140 and the protective cover 160, and prevent the protective cover 160 from slipping or shifting when subjected to external force, thereby ensuring that the protective cover 160 can always fit tightly to the outer surface of the protective shell 140 to form a complete protection system; the anti-slip texture layer 150 also makes the contact between the protective shell 140 and the protective cover 160 more stable, further improving the protection ability and stability of the nut.

[0045] Specifically, the cold-resistant layer 110 is a nickel-based alloy.

[0046] It can be understood that the cold-resistant layer 110 is made of nickel-based alloy, which has good low-temperature toughness and corrosion resistance, can maintain stable performance in extremely cold environments, and prevent the nut from becoming brittle or cracking; the excellent performance of the nickel-based alloy can also enable the nut to maintain its original mechanical strength and function under low temperature conditions.

[0047] Specifically, the reinforcement layer 120 is a carbon fiber reinforced composite material.

[0048] It can be understood that the reinforcement layer 120 is a carbon fiber reinforced composite material, which has extremely high strength and rigidity, and can effectively improve the mechanical properties of the nut, making it have better tensile, compressive and impact resistance; carbon fiber reinforced composite material has many advantages such as light weight, high strength, high temperature resistance, corrosion resistance, etc., which can significantly improve the bearing capacity and service life of the nut.

[0049] Specifically, the heat-resistant layer 130 is an aluminum oxide ceramic coating.

[0050] It can be understood that the heat-resistant layer 130 is an alumina ceramic coating, which has extremely high thermal stability and chemical stability, and can protect the nut from oxidation or corrosion in a high temperature environment, ensuring the normal operation of the nut in a high temperature environment; the high hardness and wear resistance of the alumina ceramic coating can also improve the wear resistance and service life of the nut, so that it can still maintain its original performance during long-term use; further, the alumina ceramic coating also has good insulation properties, which can effectively prevent the nut from electrical corrosion or electrical breakdown in a high temperature environment, further improving the safety and reliability of the nut.

[0051] Specifically, the first protective shell 141 and the second protective shell 142 are made of stainless steel.

[0052] It can be understood that stainless steel has good corrosion resistance, mechanical strength and processing performance, and is therefore very suitable for making the protective shell 140; the first protective shell 141 and the second protective shell 142 are made of stainless steel, thereby improving the protective performance of the protective shell 140 and effectively protecting the nut body 100 from the external environment; the excellent processing performance of stainless steel also enables the first protective shell 141 and the second protective shell 142 to be easily processed and assembled, thereby improving production efficiency.

[0053] Specifically, the protective cover 160 is a silicone protective cover 160 .

[0054] It can be understood that the silicone material has good elasticity and corrosion resistance, which can effectively enhance the protection ability of the protective shell 140 and prevent further erosion of the nut by the external environment; the softness of the silicone material also enables the protective cover 160 to fit tightly on the outer surface of the protective shell 140, forming a complete protection system, further improving the protection ability and stability of the nut.

[0055] In summary, the heat-resistant corrosion nut provided in this embodiment has excellent environmental adaptability, mechanical strength and protective ability, and can be widely used in various occasions that need to withstand high temperature, low temperature or corrosive environment. By using nickel-based alloy as the cold-resistant layer 110, carbon fiber reinforced composite material as the reinforcement layer 120, alumina ceramic coating as the heat-resistant layer 130, and a protective shell 140 made of stainless steel and a protective cover 160 made of silicone material, the heat-resistant corrosion nut provided in this embodiment has a more comprehensive and powerful protective ability, improves the adaptability and durability of the nut under various extreme conditions, and improves the safety and reliability of the equipment.
