Description

Technical Field

[0001] The utility model relates to the technical field of nuts, and in particular to a hexagonal flange nut. Background Art

[0002] A nut is a part that is screwed together with a bolt or screw for fastening. It is a component that must be used in all manufacturing machinery. According to the different materials, it is divided into several major types, such as carbon steel, stainless steel, non-ferrous metals (such as copper), etc.

[0003] Nuts are parts that tightly connect mechanical equipment. Nuts and bolts of the same specifications can be connected together through the inner thread. For example, M4-P0.7 nuts can only be connected with M4-P0.7 series bolts (in nuts, M4 refers to the inner diameter of the nut is about 4mm, and 0.7 refers to the distance between two thread teeth is 0.7mm); the same is true for American products, for example, 1 / 4-20 nuts can only be matched with 1 / 4-20 screws (1 / 4 refers to the inner diameter of the nut is about 0.25 inches, and 20 refers to 20 teeth in every inch). They can be divided into self-locking nuts, anti-loosening nuts, locking nuts, four-claw nuts, screw-in nut insurance nuts, thin-rod screw connection nuts, self-locking hexagonal cap nuts, special nuts for anchor screws, hexagonal crown thin nuts, and eye nuts. They are easy to install, do not require washers, are easy to disassemble, are reusable, are made of medium carbon steel, and can be used with grade 8.8, grade 10.9 and other high-strength bolts.

[0004] A flange nut is one that has a wide flange on one end that acts as an integrated washer. This serves to distribute the pressure of the nut across the component being secured, reducing the possibility of component damage and making it less likely to loosen due to an uneven fastening surface. Most of these nuts are hexagonal in shape and are made from hardened steel, often with a zinc finish. In many cases, the flange is fixed and turns with the nut. The flange may be serrated to provide a locking action. The serrations are angled so that the nut will not rotate in a direction that would loosen the nut. Due to the serrations, they cannot be used with washers or on scratched surfaces. The serrations help prevent vibrations of the nut from moving the fastener, thus maintaining the holding power of the nut.

[0005] During the use of the nut, it will remain connected for a long time after being fixed. Due to long-term exposure to the air, the nut will rust and corrode, which will cause the internal thread cup to rust and become unable to be separated, making it difficult to screw the nut when disassembling. The nut and the bolt will rust and cannot be screwed and disassembled, which will damage the equipment or other structures. In view of this, a hexagonal flange nut is developed. Utility Model Content

[0007] The technical solution of the utility model is as follows:

[0008] A hexagonal nut, wherein the upper end surface of the hexagonal nut is provided with a vertical frame;

[0009] A protective buckle assembly, wherein the protective buckle assembly is mounted on the vertical frame;

[0010] A connection locking assembly, wherein the connection locking assembly is arranged at the upper end of the vertical frame;
