[0022] Combine the following Figure 1-4 The utility model is further described, but the protection scope of the utility model is not limited to the described contents.

[0023] The utility model embodiment provides a copper bolt with an anti-falling structure, which includes a bolt body 1 and a nut body 2. The outer surface of the bolt body 1 is sequentially provided with a washer 3, an anti-loosening glue 4, an anti-loosening gasket 5 and the nut body 2, a conical groove 6 is provided on the middle surface of the bottom of the bolt body 1, a fixing bolt 7 is provided inside the conical groove 6, and displacement grooves 8 are respectively provided on the surrounding surfaces below the bolt body 1.

[0024] The bolt body 1 and the nut body 2 are made of copper alloy or other corrosion-resistant metals. The nut body 2 is threadedly connected to the outer surface of the bolt body 1. The washer 3 is made of iron, steel or a copper alloy of the same material. The washer 3 is threadedly contacted with the outer surface of the bolt body 1. The washer 3 is set to increase the contact area, reduce the pressure per unit area, improve the reliability of the connection, and avoid damage to the thread on the surface of the copper bolt. The anti-loosening glue 4 is made of an uncured adhesive. The anti-loosening glue 4 is applied to the outer surface of the bolt body 1. The anti-loosening glue 4 is set to increase the adhesion between the nut body 2 and the bolt body 1 formed by the thread, and increase the friction coefficient between the bolt body 1 and the nut body 2, thereby improving the anti-loosening performance of the copper bolt. The anti-loosening gasket 5 is annular in structure and is made of steel or a composite material. The anti-loosening gasket 5 is threadedly contacted with the outer surface of the bolt body 1. The anti-loosening gasket 5 is set to prevent the nut body 2 from reducing the pre-tightening force due to loosening when adjusting the pre-tightening force of the copper bolt, thereby avoiding the copper bolt from falling off during use. The washer 3 and the anti-loosening gasket The sheet 5 is connected with the bolt body 1 and the nut body 2 by a threaded connection between the nut body 2 and the surface of the bolt body 1 to form a press-fit or adhesive connection. The washer 3 and the anti-loosening gasket 5 are formed in a stable state between the nut body 2 and the bolt body 1. The conical groove 6 is engaged with the middle surface of the bottom of the bolt body 1 and is recessed. The diameter of the fixing bolt 7 is larger than the diameter of the bottom of the conical groove 6. The fixing bolt 7 is adjusted and connected with the inner thread of the bottom of the conical groove 6. The surrounding surfaces below the bolt body 1 are all in a cutting connection state with the displacement groove 8. The bottom of the bolt body 1 moves through the fixing bolt 7 and the internal thread of the conical groove 6 to make the lower surface of the bolt body 1 move outward. Through the set conical groove 6, fixing bolt 7 and displacement groove 8, the fixing bolt 7 with a diameter larger than the bottom diameter of the conical groove 6 is connected with the inner side of the bottom of the conical groove 6 through a threaded connection. The lower surface of the bolt body 1 is subjected to the expansion force brought by the fixing bolt 7. The lower surface of the bolt body 1 will move outward along the displacement groove 8 to prevent the nut body 2 threadedly connected to the surface of the bolt body 1 from being subjected to vibration or impact, resulting in the overall loosening of the copper bolt.

[0025] Working principle: After the bolt body 1 of the copper bolt with an anti-falling structure is passed through the object, it is tightened by the nut body 2. The friction force of the thread on the surface of the bolt body 1 and the effects of the washer 3, anti-loosening gasket 4 and anti-loosening glue 5 can resist the loosening tendency caused by vibration, thermal expansion and other factors. When the external force tries to loosen the copper bolt, the lower surface of the bolt body 1 is subjected to the expansion force brought by the fixing bolt 7, and the lower surface of the bolt body 1 will move outward along the displacement groove 8 to make the lower diameter of the bolt body 1 larger than the inner diameter of the nut body 2, preventing the nut body 2 connected to the thread on the surface of the bolt body 1 from being subjected to vibration or impact, causing the copper bolt to become loose as a whole and even detach from the surface of the bolt body 1, thereby improving the safety of the use of the copper bolt. The additional friction provided by the anti-loosening gasket 5 and the anti-loosening glue 4 will significantly increase the difficulty of loosening, thereby maintaining the stability and safety of the connection.
