Description

Technical Field

[0001] This utility model relates to the field of bolt technology, specifically to a bolt with anti-rust function. Background Technology

[0002] A bolt is a mechanical part, a type of fastener consisting of a head and a threaded shank (a cylinder with external threads). It needs to be used with a nut to fasten two parts with through holes. This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so a bolted connection is a detachable connection.

[0003] Existing bolts are not effective at preventing corrosion during use, which makes their surfaces prone to rust. This not only reduces the bolt's strength but also damages the threads, making the bolts loose and unable to meet usage requirements. Therefore, we propose a bolt with anti-corrosion function. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bolt with anti-corrosion function. It has the advantage of anti-corrosion function and solves the problem that the existing bolts have poor protection effect during use, which makes the surface of the bolt easy to rust. This not only reduces the strength of the bolt, but also easily leads to thread damage, which in turn makes the bolt easy to loosen and fail to meet the use requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bolt with anti-corrosion function, comprising a first bolt connector, a second bolt connector disposed at the bottom of the first bolt connector, a nut threadedly connected to the outer surface of the first bolt connector, a washer disposed at the bottom of the nut, a first functional layer disposed on the surface of the first bolt connector, the second bolt connector and the nut, the first functional layer comprising a beryllium bronze alloy plating layer and a manganese steel alloy plating layer, and a second functional layer disposed on the surface of the washer, the second functional layer comprising an ethylene propylene rubber layer and a fluorocarbon coating layer.

[0006] Preferably, a lead screw is movably connected to one side of the first bolt connector, a threaded cylinder is threaded to the surface of the lead screw, and a second bolt connector is fixedly connected to the bottom of the threaded cylinder.

[0007] Preferably, the top of the inner cavity of the first bolt connector is movably connected to the lead screw via a bearing, and a rotating handle is fixedly connected to the top of the lead screw.

[0008] Preferably, both sides of the threaded cylinder are fixedly connected to a sliding sleeve, and a sliding rod is slidably connected to the inner cavity of the sliding sleeve. One side of the sliding rod is fixedly connected to the first bolt connector.

[0009] Preferably, the beryllium bronze alloy coating is plated on the surfaces of the first bolt connector, the second bolt connector, and the nut, respectively, and the manganese steel alloy coating is plated on one side of the beryllium bronze alloy coating.

[0010] Preferably, the ethylene propylene rubber layer is fixedly connected to the surface of the gasket, and the fluorocarbon coating layer is applied to one side of the ethylene propylene rubber layer.

[0011] Compared with the prior art, this utility model provides a bolt with anti-rust function, which has the following beneficial effects:

[0012] 1. This utility model, by setting a beryllium bronze alloy coating, possesses wear-resistant, corrosion-resistant, rust-proof, and high-strength properties. By setting a manganese steel alloy coating, the wear-resistant, corrosion-resistant, rust-proof, and high-strength properties of the bolt are further improved. By setting an ethylene propylene rubber layer, it possesses weather-resistant, corrosion-resistant, and wear-resistant properties. By setting a fluorocarbon coating layer, it further improves the weather-resistant, corrosion-resistant, and wear-resistant properties of the gasket.

[0013] 2. In this utility model, rotating the handle causes the lead screw to rotate, which in turn causes the threaded cylinder to move, which in turn causes the second bolt connector to move, thereby adjusting the working length. Attached Figure Description
