Abstract

The invention relates to a double-threaded connection structure, a bolt comprises a bolt head and a screw, the section of the screw is of an annular column-shaped structure, a nut comprises a nut head and a column-shaped structure with an annular hole, the inner and outer sides of the annular column-shaped structure are both provided with first threads, the inner wall of the annular hole is provided with second threads, and the first threads and the second threads adapt to each other. As the screw is designed to have the annular structure, the inner and outer sides of the annular structure are both provided with the threads to which the threads in the annular hole of the nut adapt, the connection structure of bi-directional threads can be realized, the connection structure is difficult to fracture and can not cause broken wire, and the connection structure is stable.

Description

technical field

[0001] The invention relates to a double thread connection structure, which belongs to the field of connectors. Background technique

[0002] At present, the thread connection structure adopts unidirectional thread connection, and the connection structure is easy to loose due to the transverse shear force after connection, which affects the connection effect or product quality. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a double-threaded connection structure, which overcomes the defect that the threaded connections in the prior art all adopt unidirectional threaded connections, resulting in the easy loosening of the connection structure.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a double-threaded connection structure includes a bolt and a nut, the bolt includes a bolt head and a screw rod, and the screw rod is an an...
