[0002] Anti-seismic anti-loosening bolts are fasteners designed to prevent loosening in a vibrating environment. Such bolts are usually used in equipment that requires high stability and reliability. Commonly used anti-loosening methods are friction anti-loosening, mechanical anti-loosening and weld anti-loosening. Among them, mechanical anti-loosening uses special structures or auxiliary components to physically lock the bolts to prevent them from loosening.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] In order to save manpower and improve efficiency, as an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, the utility model describes an anti-seismic and anti-loosening bolt, comprising a bolt body 1, a connecting cover 2, a nut 12 and a connecting pipe 21. A connecting column 13 is welded to one side of the outer wall of the lower end of the bolt body 1, and a limiting groove 14 is provided inside the connecting column 13. A connecting cover 2 is provided on one side of the lower end of the outer wall of the bolt body 1, a connecting pipe 21 is installed on the outer wall of the lower end of the connecting cover 2, and a second gasket 24 is provided on the outer wall of the upper end of the connecting cover 2.

[0029] When in use, the connecting tube 21 can be fixed to the outside of the connecting column 13 by the retaining spring 23, keeping the connecting tube 21 in a stable position on the outside of the bolt body 1. The connecting cover 2 fills the gap between the nut 12 and the second gasket 24 to ensure that the connecting cover 2 supports the nut 12 stably.

[0030] To fix the mounting member, for example, Figure 2 As shown, a nut 12 is threadedly connected to the outer wall of one side of the bolt body 1 , and a first washer 11 is provided on the outer wall of the upper end of the nut 12 . The first washer 11 is located outside the bolt body 1 .

[0031] During use, the staff puts the bolt body 1 into the fixing hole of the mounting piece, and the bolt body 1 cooperates with the first washer 11 and the nut 12 to assemble and connect the mounting piece.

[0032] In order to place the retaining spring 23, for example, Figure 4 As shown, receiving grooves 22 are provided on both sides of the inner wall of the connecting tube 21 , the connecting column 13 is located inside the connecting tube 21 , and the inner wall dimensions of the receiving grooves 22 and the limiting grooves 14 are consistent.

[0033] When in use, the connecting pipe 21 can maintain a stable position outside the connecting column 13 , thereby protecting the use position of the connecting cover 2 .

[0034] In order to fix the connection cover 2, for example, Figure 4 As shown, a retaining spring 23 is provided inside the limiting groove 14 , and outer walls at both ends of the retaining spring 23 protrude from the outside of the connecting pipe 21 .

[0035] When in use, the retaining spring 23 is inserted into the limiting groove 14 and the receiving groove 22 to limit the use position of the connecting tube 21 and ensure that the connecting tube 21 is firmly positioned outside the connecting column 13 .

[0036] For the purpose of limiting, for example, Figure 3 As shown, the second gasket 24 and the outer wall of the upper end of the connecting cover 2 are both provided with an embedding groove 25 , and the outer wall of the lower end of the second gasket 24 is both provided with an embedding block 26 , which is located inside the embedding groove 25 .

[0037] During use, the interlocking groove 25 and the interlocking block 26 can stabilize the placement of the second gasket 24 at the upper end of the connecting cover 2, ensure that the second gasket 24 moves stably with the connecting cover 2, ensure that the second gasket 24 moves in a controlled manner, and avoid the second gasket 24 from damaging the threads on the surface of the bolt body 1.

[0038] In order to block the nut 12, for example, Figure 1 As shown, the outer wall of the upper end of the second washer 24 contacts the outer wall of the lower end of the nut 12 , and the size of the second washer 24 is smaller than that of the nut 12 .

[0039] During use, the distance between the connection cover 2 and the nut 12 can be shielded by increasing or decreasing the number of stacked second washers 24 , thereby ensuring the squeezing force of the connection cover 2 on the nut 12 .

[0040] When the present invention is in use, the staff manually takes the bolt body 1 and places it in the assembly hole of the mounting piece. Afterwards, the staff places the first gasket 11 on the outside of the bolt body 1, and the first gasket 11 is located on the other side of the mounting piece. The staff manually rotates the nut 12 to rotate the nut 12 to the outside of the bolt body 1, and tightens the nut 12 with a wrench. The mounting piece can be connected and assembled through the bolt body 1, the first gasket 11 and the nut 12.

[0041] The staff manually takes the connecting cover 2 and the second gasket 24 and places them on the outside of the bolt body 1. The connecting cover 2 and the second gasket 24 can shield and protect the exposed threads of the bolt body 1.

[0042] The interlocking block 26 and the interlocking groove 25 can limit the position of the second gasket 24 at the upper end of the connecting cover 2, and by increasing the number of stacked second gaskets 24, the distance between the connecting cover 2 and the nut 12 can be blocked, thereby ensuring the squeezing force of the connecting cover 2 on the nut 12;

[0043] The staff takes the retaining ring 23 and inserts it into the receiving groove 22 and the limiting groove 14 to limit the connecting pipe 21 and keep the connecting pipe 21 stable at the position outside the connecting column 13.
