In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a connection between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] Reference Figure 1-3The utility model provides an embodiment: a high-strength copper bolt, including a bolt body 1, the bolt body 1 includes a stud 2 and a bolt head 3, the stud 2 and the bolt head 3 are an integrated structure made of brass, the outer surface of the bolt head 3 is provided with an external thread, and a reinforced inner core 4 is provided in the stud 2. The material of the reinforced inner core 4 is manganese-titanium-boron steel, and the cross-section of the reinforced inner core 4 is plum blossom-shaped. The reinforced inner core 4 made of manganese-titanium-boron steel has excellent structural strength, and each corner of the plum blossom-shaped reinforced inner core 4 is in a conical form, which can enhance the strength of the entire bolt. The anti-deformation and anti-torsion capabilities of the column 2 make the entire bolt less likely to bend and break, effectively enhancing the structural strength of the entire copper bolt, thereby enhancing the durability of the entire bolt and extending its service life. The outer surface of the stud 2 is provided with an outer protective layer 5, and the outer protective layer 5 is a galvanized surface layer. Adding a layer of galvanized protective structure on the surface of the stud 2 can form a passivation film on its surface, thereby improving the corrosion resistance and wear resistance of the entire bolt, thereby enhancing the overall structural strength of the bolt and enhancing the durability of the entire bolt. A locking hole 6 is provided on the outer surface of the bolt head 3, and a positioning plate 7 is provided on the outer side of the bolt head 3. A positioning bayonet 8 is provided at the center of the positioning plate 7, and a movable groove 9 is provided in the positioning plate 7. A moving block 10 and a spring 11 are respectively provided in the movable groove 9. A locking pin 12 is fixedly connected to the outer surface of the moving block 10 away from the spring 11. The bolt head 3 and the positioning bayonet 8 are nested and matched, and the locking pin 12 and the locking hole 6 are nested and matched. The setting of the positioning bayonet 8 can dock the positioning plate 7 with the bolt head 3, and cooperate with the setting of the locking pin 12 and the locking hole 6. The positioning can make the two be stably positioned together, which is convenient for the subsequent positioning and fixing of the copper bolts, avoiding the situation where the bolts are loosened due to the vibration generated when the machine is running, and ensuring the stability of the bolt positioning installation. The moving block 10 is fixedly connected with an operating rod 13, and a mounting hole 15 is provided on the positioning plate 7. A fastening bolt 16 is provided in the mounting hole 15. The fastening bolt 16 passes through the mounting hole 15 and can be tightened and positioned on the machine housing. In this way, the positioning plate 7 can be positioned stably, and a stable limiting effect on the bolt head 3 can be achieved.

[0028] There are six locking holes 6 located at six side positions of the bolt head 3, and there are two locking pins 12 located at corresponding positions on both sides of the inner wall of the positioning bayonet 8. The two locking pins 12 can be docked and installed with any two opposite locking holes 6 on the bolt head 3, which makes it convenient to adjust the orientation of the positioning plate 7 for positioning and installation.

[0029] The outer surface of the positioning plate 7 is provided with a guide groove 14 connected to the movable groove 9. The operating rod 13 and the guide groove 14 are nested and slidably matched. The setting of the guide groove 14 allows the operating rod 13 to slide normally, which can facilitate the movement of the moving block 10, thereby facilitating the locking pin 12 to perform disassembly and assembly operations.

[0030] Working principle: When using high-strength copper bolts, the structural strength of the entire bolt body 1 can be enhanced by strengthening the setting of the inner core 4, and its deformation and torsion resistance can be enhanced. The corrosion resistance and wear resistance of the entire bolt can be enhanced by setting the outer protective layer 5, which can effectively enhance the durability of the entire bolt. When the copper bolt is tightened onto the machine housing, the sliding operating rod 13 drives the locking pin 12 to contract through the moving block 10, and drives the moving block 10 to compress the spring 11, so that the positioning bayonet 8 is connected to the bolt head 3, and the operating rod 13 is released. The spring 11 resets and pushes the moving block 10 to drive the locking pin 12 to insert into the locking hole 6, and the positioning installation of the structure can be completed. The positioning plate 7 is positioned and installed on the machine housing by tightening the bolt 16, so that the copper bolt can be stably fixed and protected to a certain extent, thereby avoiding the loosening of the bolt due to vibration of the machine equipment or external force.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
