Fig. 1 is a structural view of the present invention.
Description of reference numerals:
the steel pipe comprises a large round steel pipe 1, a small round steel pipe 2, a connecting joint 3, a conical thread 4, a plastic sleeve 5, a decorative sleeve 6 and a convex ring 7.
Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
Referring to fig. 1, the following technical solutions are adopted in the present embodiment: the steel pipe comprises a large round steel pipe 1, a small round steel pipe 2, a connecting joint 3, a conical thread 4 and a plastic sleeve 5; the small round steel pipe 2 is inserted into the large round steel pipe 1, a connecting joint 3 is fixed at one end of the small round steel pipe 2, a conical thread 4 is arranged on the surface of the connecting joint 3, an internal thread is arranged in the plastic sleeve 5, and the plastic sleeve 5 is screwed with the conical thread 4.
One end of the large round steel pipe 1 is fixed with a decorative sleeve 6, the decorative sleeve 6 plays a decorative role, the end part of the inner ring of the decorative sleeve 6 is provided with a convex ring 7, and when the small round steel pipe 2 is pulled, the convex ring 7 enables the small round steel pipe 2 not to be pulled out, so that a limiting role is played.
The connecting joint 3 is a plastic connecting joint.
The working principle of the specific embodiment is as follows: the rotary large round steel pipe 1 is connected with the threads in the plastic sleeve 5 through the taper threads 4, and the connecting joint 3 is screwed more and more tightly with the internal threads of the plastic sleeve 5 in the further screwing process, so that the plastic sleeve 5 is opened to be tightly matched with the inner wall of the large round steel pipe 1, and the purpose of firm connection is realized.
The basic principles and main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
