[0002] In the field of high-strength connection and wear resistance, as a key fastener, the performance of the bolt is directly related to the stability and safety of the mechanical equipment. However, when the traditional bolt works under high load or in harsh environment, problems such as wear, loosening and even fracture often occur, which seriously affects the service life and reliability of the bolt. Especially after the nut bolt wears, it is difficult to disassemble, which leads to difficult maintenance in the later period. SUMMARY

[0003] The main purpose of the utility model is to provide a high-strength wear-resistant bolt, which aims to improve the connection stability and wear resistance of the bolt, reduce the wear of the nut and facilitate subsequent maintenance.

[0004] To achieve the above purpose, the utility model provides a high-strength wear-resistant bolt, which comprises a bolt body, the bolt body comprises a nut and a screw rod, the top of the nut is provided with a polygonal groove, a ring-shaped connecting groove is arranged outside the polygonal groove, a wear-resistant cover plate is arranged above the nut, a ring-shaped mounting protrusion is arranged at the bottom of the wear-resistant cover plate, and the diameter of the ring-shaped mounting protrusion is the same as that of the circular ring-shaped connecting groove.

[0005] The high-strength wear-resistant bolt provided by the utility model is composed of a nut and a screw rod, which is the basic structure of the bolt and is used to realize the functions of connection and fastening. The polygonal groove is used for rotating to rotate the bolt, and the ring-shaped connecting groove is arranged on the periphery of the polygonal groove to connect the wear-resistant cover plate. The wear-resistant cover plate is used to protect the bolt head and reduce wear, thereby prolonging the service life of the bolt. The wear-resistant cover plate is provided with a ring-shaped mounting protrusion at the bottom, and the diameter of the ring-shaped mounting protrusion is the same as that of the ring-shaped connecting groove. This design helps to ensure the close fit between the cover plate and the nut, reduces the wear of the nut, and facilitates subsequent maintenance.

[0006] In a possible implementation manner, the diameter of the wear-resistant cover plate is smaller than the diameter of the nut.

[0007] In a possible implementation manner, a rectangular groove is arranged on the wear-resistant cover plate, a straight rod is arranged in the rectangular groove, and the two ends of the straight rod are arranged on the inner side wall of the rectangular groove. This structure facilitates the operation of the wear-resistant cover plate and facilitates the installation and disassembly of the wear-resistant cover plate.

[0008] In a possible implementation manner, the contour of the polygonal groove is a regular hexagon. The contour of the polygonal groove is a regular hexagon, and this regular geometric shape helps to realize accurate installation and positioning.

[0009] In one possible implementation, the annular connecting groove is threaded, and the outer wall of the annular mounting protrusion is also threaded. This design, with threads in both the annular connecting groove and the outer wall of the annular mounting protrusion, facilitates a secure connection with other components.
