Description

Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to a wear-resistant hot-dip galvanized bolt. Background Art

[0002] Bolts are a common fastener, often used to connect two or more parts. Bolts usually consist of a head and a screw. The head is hexagonal, round or a special shape, and the screw has threads. Bolts are usually made of metal, such as steel, stainless steel, copper, etc.

[0003] The working principle of the bolt is to use the engagement principle of the thread. The bolt is passed through the parts to be connected and then fixed with a nut. In the process of tightening the nut, the threads between the bolt and the nut engage with each other, causing friction between the bolt and the parts, thereby achieving a tightened connection.

[0004] Bolts, as a commonly used fastener, have the following advantages:

[0005] Easy to disassemble: Bolt connections are removable. Bolts can be easily removed using a corresponding wrench or screwdriver, making it easy to repair, replace or adjust parts.

[0006] Wide range of applications: Bolts are suitable for various occasions, such as machinery, construction, automobiles, aviation and other fields. Bolts of different materials, specifications and standards can meet different usage requirements;

[0007] Simple manufacturing: The manufacturing process of bolts is relatively simple and can be made by cold heading, cutting, casting and other methods. Therefore, the cost of bolts is low and the supply is sufficient.

[0008] As a simple, reliable and easy-to-disassemble fastener, bolts are widely used in various fields, providing convenience for people's lives and production activities.

[0009] At present, conventional bolts are all made of a single metal. Due to the single material, the wear and corrosion resistance is poor. After long-term assembly and use, the surface of the bolts is prone to rust, which causes the bolts to slip. At the same time, most bolts are still installed manually during assembly, but the way to twist the bolts is single, all of which are operated with a wrench. However, in some narrow spaces, the wrench is easy to be inconvenient to twist due to length problems, resulting in inconvenience in bolt assembly. Utility Model Content

[0010] The utility model aims to solve the above-mentioned shortcomings in the prior art and proposes a wear-resistant hot-dip galvanized bolt.

[0011] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0012] A wear-resistant hot-dip galvanized bolt is designed, comprising a bolt body, wherein the bolt body comprises a bolt rod and a bolt end, wherein the bolt rod and the bolt end are an integrated structure, an external thread is provided on the surface of the bolt rod, and the external thread extends from one end of the bolt rod to the bolt end, a conical protrusion is provided at the end of the bolt rod, at least two notches are provided on the outer ring wall of the bolt end, and the notches are evenly distributed along the outer ring wall of the bolt end, and the number of the notches is an even number, and a knob is provided on the other side of the bolt end, and one end of the knob is welded and fixed to the end face of the bolt end.

[0013] In detail, the bolt end is a hexagonal structure.

[0014] In detail, there are two knobs, which are symmetrically distributed along the center of the bolt end.

[0015] In detail, the bolt rod comprises a core layer, a durable layer and a protective layer. The durable layer is electroplated on the outer wall surface of the core layer, and the protective layer is coated on the surface of the durable layer. The bolt end has the same material composition as the bolt rod.

[0016] In detail, the core layer is made of stainless steel material. Stainless steel has good corrosion resistance in the air or in specific chemical media. This is because a dense oxide film is formed on the surface of the stainless steel to protect the steel from further corrosion. Stainless steel has high wear resistance and is suitable for manufacturing various wear-resistant parts.

[0017] In detail, the durable layer is made of galvanized material, which is a common metal surface treatment technology. A layer of zinc is plated on the metal surface to improve the corrosion resistance of the metal. Zinc can react with oxygen in the air to form a dense zinc oxide film to protect the metal from further corrosion. Therefore, the galvanized metal has good corrosion resistance. Zinc has good antioxidant properties and can protect the metal from oxidation in high temperature environments. Zinc can prevent metals such as steel from rusting and extend the service life of metal products.

[0018] In detail, the protective layer is made of plastic material. Plastic has good plasticity and can be made into products of various shapes and sizes through processing methods such as injection molding and extrusion. Plastic has high insulation performance and can be used to manufacture electrical products such as wires and cables. Plastic has good corrosion resistance to chemical substances such as acids, alkalis, and salts.

[0019] The design scheme proposed by the utility model has the following beneficial effects during application:

[0020] 1. A complete bolt structure can be formed by the bolt rod and the bolt end. The bolt end is a hexagonal structure, which conforms to the current conventional bolt shape. A notch structure is opened on the bolt end, with at least two notches and an even number, which can be convenient for clamping with pliers, thereby increasing the assembly method of the bolt during installation or disassembly. Furthermore, two knob structures are welded on the bolt end, which can be directly twisted manually when the bolt is initially connected, thereby improving the efficiency of bolt installation.

[0021] 2. The material composition of the bolt rod and the bolt end is the same. Using stainless steel as the base layer can ensure the lightness of the bolt structure. Stainless steel itself has certain wear and corrosion resistance. Adding a galvanized layer on the surface of the stainless steel can further improve the wear and corrosion resistance of the bolt during long-term use. The galvanized layer is coated with a plastic layer to reduce the loss of the external thread during bolt assembly. For structures that are repeatedly disassembled and assembled, the durability and wear resistance of the external thread can be improved to avoid thread slippage. BRIEF DESCRIPTION OF THE DRAWINGS
