Detailed Description
For the purpose of making apparent the objects, technical solutions and advantages of the present utility model, the present utility model will be further described in detail with reference to the accompanying drawings and examples, it being understood that the specific examples described herein are for illustration only and are not intended to limit the present utility model.
Referring to fig. 1, 3 and 4, the utility model provides a novel special-shaped steel pipe, which comprises a thick circular pipe connecting part 1, a thin circular pipe connecting part 2 and a transition part 3 for connecting the thick circular pipe connecting part and the thin circular pipe connecting part with a certain taper; the inner pipe wall of the thick circular pipe connecting part 1 is provided with a thread structure; the diameter difference between the thick circular tube connecting part 1 and the thin circular tube connecting part 2 can be set according to the requirement, and the taper of the transition part 3 can be set according to the requirement.
An extension part 4 is arranged at one end of the transition part 3, which is close to the thin circular tube connecting part 2, in this embodiment, the extension part 4 is in a cylindrical structure, and a thread structure 41 matched with the thick circular tube connecting part 1 is arranged on the outer wall of the extension part 4.
When the device is used (two groups of concentric special-shaped tube circular tubes are combined), only the thin circular tube connecting part 2 of one group of concentric special-shaped tube circular tubes is inserted into the thick circular tube connecting part 1 of the other group, and then the extending part 4 and the thick circular tube connecting part 1 are assembled in a matched mode (the assembly is carried out through a threaded structure).
