Embodiment 1

[0023] Such as figure 1 The connecting pipe system shown has a male head pipe 1 and a female head pipe 2. There is a stepped hole inside the female head pipe 2. The stepped hole divides the female head pipe into a large-aperture part 21 and a small-aperture part 24. The male head pipe 1 The end portion is inserted into the large aperture portion 21 of the female head pipe 2 .

[0024] Such as figure 2 The outer wall of the male pipe 1 is provided with an external thread 12, the external thread 12 is arranged on the top of the male pipe, and the outer wall of the male pipe 1 is also provided with two installation grooves 11 surrounding the section of the male pipe 1, wherein the installation groove The cross-section is rectangular, and the installation groove 11 is a ring-shaped closed structure and is arranged at the lower part of the external thread 12, such as image 3 As shown, the corresponding position of the female head pipe 2 is provided with an internal thread 22 ma...

Embodiment 2

[0031] Such as figure 1 The connecting pipe system shown has a male head pipe 1 and a female head pipe 2. There is a stepped hole inside the female head pipe 2. The stepped hole divides the female head pipe into a large-aperture part 21 and a small-aperture part 24. The male head pipe 1 The end portion is inserted into the large aperture portion 21 of the female head pipe 2 .

[0032] The outer wall of the male pipe 1 is provided with an external thread 12, the external thread 12 is arranged on the upper part of the male pipe, and the outer wall of the male pipe 1 is also provided with four installation grooves 11 surrounding the cross section of the male pipe 1, wherein the cross section of the installation groove is Rectangular, the mounting groove 11 is a ring-shaped closed structure, and two pairs are respectively arranged on the upper part and the lower part of the external thread 12, and the corresponding position of the female head pipe 2 is provided with an internal th...

Abstract

The invention proposes a connecting pipe system. The connecting pipe system comprises a male head pipe and a female head pipe; a step hole is formed in the female head pipe for dividing the female head pipe into a large-aperture part and a small-aperture part; the end part of the male head pipe is inserted in the large-aperture part of the female head pipe; and the male head pipe and the female head pipe are sealed through a thread connecting and sealing structure. Through the structures of a thread and a sealing ring, the pipe sealing effect is better; and after the female head pipe is expanded, through matching of internal and external threads and reinforcement of the sealing ring, a connecting part reaches a dual sealing effect, other redundant processes are not needed, the operation flow is reduced, and the equipment quality and the production efficiency are improved.

Description

technical field [0001] The invention relates to the field of hardware and building materials, in particular to a connecting pipe system. Background technique [0002] Generally, connecting pipes in the field of hardware and building materials are connected by sockets or threaded fittings, but pipes in the field of building materials are mostly used as water pipes, and liquid and semi-liquid substances pass through them. The pipe fittings in the prior art are prone to problems such as running water overflowing due to gaps in threads. When the pipeline needs to hold large particles or corrosive liquid, the liquid passing through the thread will cause corrosion or rust on the thread. Contents of the invention [0003] The invention proposes a connecting pipe system, which solves the problems in the prior art that the connecting pipe is easy to leak or the thread is easily damaged. [0004] Technical scheme of the present invention is realized like this: [0005] The connec...
