Problems solved by technology

[0002] Nuts are parts that are screwed together with bolts or screws for fastening. Some nuts need to be exposed to the outdoors, and they are easily oxidized by water in the air and cause rust. This not only affects the appearance, but is also difficult to disassemble. Sometimes only It can be cut with a saw, which wastes the cost
The existing cap nut cap is smaller than the nut and has poor corrosion resistance

Embodiment Construction

[0010] Attached icon number: 1. Nut body, 2. Cap, 3. Sealing rubber.

[0011] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] The structure of the present invention is as figure 1 As shown, a rust-proof cap nut is characterized in that it comprises a nut body 1 and a cap 2 integrally formed with the nut body 1. The nut body 1 is in the shape of a hexagonal prism, and the diameter ratio of the cap 2 to the nut body 1 is 2:1, the cap 2 is larger than the nut, and the arc on the top of the cap 2 can throw off the rain, thereby effectively preventing the outside air and moisture from entering; the nut body 1 is nickel-plated, and the nut can quickly on the surface A very thin passivation film is formed, which is highly stable in the air; a sealing rubber 3 is sleeved on the cap 2, which can res...

Abstract

The invention discloses a rust-proof cap nut. The rust-proof cap nut is creatively characterized in that the cap nut comprises a nut body and a nut cap, wherein the nut body and the nut cap are integrally formed; the nut body is in a prism shape, the direct ration of the nut cap and the nut body is 2 to 1, and the nut body is treated through a nickel plating process; and the nut cap is sleeved with sealing rubber. According to the rust-proof cap nut, the rust-proof cap nut is protected against rust by the nut cap and the sealing rubber; the size of the nut cap is larger than that of the nut body, rain can be thrown off through the radian of the top of the nut cap, and therefore air and moisture in the outside are prevented from entering the cap nut effectively; the nut body is treated through the nickel plating process, a layer of razor-thin passive film can be generated on the surface of the nut quickly, and the stability in the air is very high; and the nut cap is sleeved with the sealing rubber and thus capable of being resistant to corrosion by the atmosphere, alkali and some acids.

Description

Technical field [0001] The invention relates to a threaded connection piece, in particular to a rust-proof cap nut. Background technique [0002] Nuts are parts that are screwed together with bolts or screws for fastening. Some nuts need to be exposed to outdoor use, and they are easily oxidized by water in the air and cause rust. They not only affect the appearance, but are also difficult to disassemble, sometimes only It can be cut with a saw, which wastes cost. The existing cap nut has a cap smaller than a nut and has poor corrosion resistance. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a rust-proof cap nut used in an open working environment. [0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a rust-proof cap nut. The innovation is that it comprises a nut body and a cap integrally formed with the nut body, and the nut body is in the shape of ...
