Abstract

The utility model discloses a connection structure of inclined connection pipes of H pipes. The connection structure comprises two vertical pipes which are arranged side by side, and the inner sides of the vertical pipes are provided with the inclined connection pipes respectively, wherein the inclined connection pipes are connected in an up-and-down corresponding mode in an inclined mode. The end faces of the connection ends of the inclined connection pipes are provided with clamping grooves respectively, and sealing rings are clamped into the clamping grooves. The connection segment of one inclined connection pipe is provided with a step segment, wherein an inner thread is arranged in an inner hole of the step segment, and an outer thread is arranged on the outer side wall of the step segment. An outer thread matched with the inner thread of the step segment is arranged at an end portion of the other inclined connection pipe, wherein the rear end portion of the outer thread is a step segment, and the outer side wall of the step segment of the rear end portion of the outer thread is also provided with an outer thread and screwed with a sleeve. The two step segments are equal in diameter, and the sleeve can be screwed with the corresponding outer thread of the step segment which is in abut joint with the sleeve. According to the connection structure of the inclined connection pipes of the H pipes, the sealing performance of the connection structure is ensured through the sealing grooves in the end portions of the inclined connection pipes; the connection stability between the inclined connection pipes is increased through the structural design of the sleeve, threaded connection and the structure of the sleeve; the connection structure is not prone to loosening and capable of meeting use requirements.

Description

A kind of linkage structure of inclined pipe of H pipe

Technical field

The utility model relates to pipeline field, relates in particular to a kind of linkage structure of inclined pipe of H pipe.

Background technique

The linkage structure of the inclined pipe of existing H pipe is simple, and the inclined pipe between standpipe connects simple, and installation coordinates insecure, and easily loosening, stability is poor, and poor sealing performance, can not meet usage requirement simultaneously.

Model utility content

The purpose of this utility model is in order to make up the deficiency of prior art, and a kind of linkage structure of inclined pipe of H pipe is provided.

The utility model is achieved through the following technical solutions:

A kind of linkage structure of inclined pipe of H pipe, include two standpipes arranged side by side, the inner side of described standpipe is respectively equipped with the inclined pipe that upper and lower corresponding tilt connects, it is characterized in that: on the end face of the connecting end of described inclined pipe, be respectively equipped with draw-in groove, in described draw-in groove, be installed with seal ring, and the linkage section of one of them inclined pipe is provided with step section, in the endoporus of step section, be provided with internal thread, the outer side wall of step section is provided with outside thread, the end of another inclined pipe is provided with the outside thread with step section screw-internal thread fit, position, described outside thread rear end step section, on the outer side wall of its step section, be also provided with outside thread, and be combined with sleeve, the diameter of described two step sections is identical, the outside thread of the step section that described sleeve can dock with it screws.

The utility model has the advantages that:

The utility model reasonable in design, by the seal groove of inclined pipe end, has guaranteed its sealability, by the structural design of sleeve, be threaded connection and the structure of sleeve, increased the stability of the connection between inclined pipe, be not easy to become flexible, met usage requirement.
