Description

Technical Field

[0001] The utility model relates to the field of nuts, in particular to a high-wear-resistant and high-torsion spot-welded nut. Background Art

[0002] A welding nut is a nut suitable for welding outside a nut. Welding nuts have the advantages of high strength and a wide range of uses. They can be thin or thick, but high temperatures can cause deformation of the connected parts and they cannot be disassembled. At the same time, wear resistance must also be considered during use. Therefore, they need to be continuously designed based on their characteristics. A highly wear-resistant and high-torque spot welding nut disclosed in application number CN202320030684.4 is found. It records a welding disk, an anti-slip ring, a spot welding protrusion, and a spherical groove. The nut body can be welded and fixed to an object through the welding disk, thereby increasing the contact area between the nut body and the object and making it more stable after welding. The nut body is fixed and convenient for welding operation; the wear-resistant inner layer, wear-resistant outer layer, anti-corrosion layer and hardness reinforcement layer are set to improve the overall strength of the nut body, and the nut body has better wear resistance and corrosion resistance. However, the above description still has the following defects in actual use: when the spot-welded nut is used, several spot-welding protrusions on the surface of the welding disk will affect the twisting work of the nut body after welding, and the welding disk of this shape is not suitable for some smaller-sized welding parts. At the same time, damage to the two side patches will affect the disassembly and use of the nut body. Therefore, it is necessary to design a practical, highly wear-resistant and high-torque spot-welded nut. Utility Model Content
