Description

Technical Field

[0001] The utility model relates to the technical field of nuts, in particular to a novel corrosion-resistant nut. Background Art

[0002] A nut, also known as a cap, is a component used in conjunction with a bolt or screw, primarily for fastening and is an indispensable component in manufacturing machinery. The nut's inner threads tightly connect to the bolt or screw, firmly securing the various parts of the machinery together. This ensures the stability and safety of the equipment and prevents equipment failure or accidents caused by loosening. Furthermore, the nut's easy installation and removal facilitates maintenance and upkeep of the machinery, improving production efficiency.

[0003] When existing nuts are connected to bolts or screws, the nuts have no protective structure and are directly exposed to the outside, which is easily affected by corrosion from the external environment, causing the nut's tightening force to fail, resulting in loose connection and performance degradation. In addition, after installation, the nuts are not further tightened, and the nuts are easily affected by shaking and become loose and fall off. Utility Model Content

[0004] The main purpose of the utility model is to provide a novel corrosion-resistant nut, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A new type of corrosion-resistant nut includes a nut, a protective sleeve is installed on the outer surface of the nut, and a rotating handle is installed on the right end of the nut and the protective sleeve; an anti-corrosion layer is provided on the outer surface of the nut, a threaded groove is opened at the right end of the nut, a clamping threaded rod is inserted and fixedly installed at the left end of the rotating handle, and the rotating handle is threadedly installed on the right end of the nut through the clamping threaded rod; an installation groove is opened in the protective sleeve, and a through opening is opened at the right end of the protective sleeve.

[0007] The nut is made of aluminum alloy and an anti-corrosion layer is provided on the outer surface of the nut, so that the nut has good wear resistance, corrosion resistance, high temperature impact resistance and other characteristics. At the same time, a protective sleeve is also sleeved on the outer surface of the nut to further protect the nut, so that the nut has better performance. In addition, by rotating the handle, the clamping threaded rod is screwed into the nut, thereby further clamping the nut to prevent the nut from loosening easily.

[0008] Preferably, the nut is made of aluminum alloy.

[0009] Preferably, an anti-corrosion layer is also provided on the outer surface of the clamping threaded rod.

[0010] Preferably, the thread groove corresponds to the position of the through opening on the left and right, and the thread groove matches the size of the clamping thread rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The nut is made of aluminum alloy, so the nut has good corrosion resistance and high strength. Its rigidity exceeds that of steel and its strength is close to that of high-alloy steel. In addition, the anti-corrosion layer on the outer surface of the nut is designed by micro-arc oxidation, that is, plasma electrolytic oxidation technology, which uses arc discharge to form a ceramic coating on the surface of metals such as aluminum, magnesium, and titanium, further improving the hardness of the nut. It also makes the nut have good wear resistance, corrosion resistance, and high temperature impact resistance, and the insulation resistance can reach more than 100MΩ. At the same time, the ceramic film is firmly bonded to the nut matrix, and the structure is dense and uniform. In addition, a protective sleeve is also sleeved on the outer surface of the nut to further protect the nut, so that the nut has better performance.

[0013] 2. After the nut is installed on the bolt or screw, pass the clamping thread rod through the opening and align it with the thread groove. At this time, turn the handle to screw the clamping thread rod into the nut, thereby further clamping the nut to prevent the nut from loosening easily. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the clamping threaded rod 12 is screwed into the nut 1 by rotating the handle 3, thereby further clamping the nut 1 to prevent the nut 1 from loosening easily. Moreover, the nut 1 is made of aluminum alloy, so the nut 1 has good corrosion resistance and high strength, and its rigidity exceeds that of steel and its strength is close to that of high-alloy steel. In addition, the design of the anti-corrosion layer 10 on the outer surface of the nut 1 is that the anti-corrosion layer 10 is formed by micro-arc oxidation, that is, plasma electrolytic oxidation technology, using arc discharge to form a ceramic coating on the surface of metals such as aluminum, magnesium, and titanium, further improving the hardness of the nut 1, and making the nut 1 have good wear resistance, corrosion resistance, and high temperature impact resistance, and the insulation resistance can reach more than 100MΩ. At the same time, the ceramic film is firmly bonded to the nut 1 matrix, and the structure is dense and uniform. In addition, a protective sleeve 2 is also sleeved on the outer surface of the nut 1 to further protect the nut 1, so that the nut 1 has better performance.
