In the figure: 1. a nut body; 2. a hexagonal surface; 201. a substrate; 202. a rust-proof layer; 203. an anti-corrosion layer; 204. a wear layer; 205. a waterproof layer; 3. a straight-line-shaped groove.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a cutting knife top board hexagonal lock nut for pivot, including nut body 1, nut body 1's fixed surface is connected with hexagonal surface 2, a style of calligraphy recess 3 has been seted up to nut body 1's one end, hexagonal surface 2 includes base member 201, base member 201's fixed surface is connected with antirust coat 202, antirust coat 202's fixed surface is connected with anti-corrosion coating 203, cooperation through hexagonal surface 2 and a style of calligraphy recess 3, the user can use corresponding open-ended spanner or adjustable spanner to cooperate the operation, effectual stability when having improved user dismouting nut, thereby avoided the cutting knife to lead to normally twisting the problem of moving the nut around the plumbum rotation of axle.

Specifically, the surface of the anti-corrosion layer 203 is fixedly connected with the wear-resistant layer 204, the wear-resistant layer 204 is wear-resistant ceramic paint, the wear-resistant ceramic paint has good wear resistance, the wear resistance of the hexagonal surface 2 can be improved by arranging the wear-resistant layer 204, and the anti-corrosion layer 203 and the anti-corrosion layer 202 are effectively prevented from being worn.

Specifically, the fixed surface of wearing layer 204 is connected with waterproof layer 205, and waterproof layer 205 is super hydrophobic coating, and super hydrophobic coating has good liquid guiding nature, can effectually avoid machine oil to bond on the nut surface, and more person of facilitating the use uses.

Specifically, the anti-rust layer 202 is red lead anti-rust paint, the anti-corrosion layer 203 is fluorocarbon finish paint, the red lead anti-rust paint has good anti-rust property, the fluorocarbon finish paint has good corrosion resistance, and the anti-rust property and the corrosion resistance of the hexagonal surface 2 can be greatly improved by compositely using the red lead anti-rust paint and the fluorocarbon finish paint, so that the environmental adaptability of the nut is improved, and the use is facilitated.
