Description

a pipe joint

technical field

The utility model relates to a pipe joint, in particular to a pipe joint that can be quickly installed and disassembled.

Background technique

Pipe joints are commonly used parts in our industrial production and life, used to connect pipes, valves, faucets and other parts; traditional pipe joints are often connected with the pipes to be connected by the threads at both ends. Trouble, it often takes a lot of time, inefficiency, and greater work intensity when installing and disassembling.

Contents of the invention

In order to overcome the shortcomings of the prior art, the utility model provides a pipe joint that can be quickly installed and disassembled, which effectively saves time, improves work efficiency and reduces work intensity.

The technical scheme that the utility model solves its technical problem adopts is:

A pipe joint, comprising a connecting pipe, the end of the outer wall of the connecting pipe is provided with a retaining ring installation groove, the retaining ring is installed in the retaining ring installation groove, the end of the outer wall is also sleeved with a nut, and the nut is provided with a A threaded hole, one end of the threaded hole is provided with a ring of protrusions higher than the thread, and the inner diameter of the protrusion is smaller than the outer diameter of the retaining ring.

As an improvement of the above technical solution, a sealing groove is provided at the end of the outer wall of the connecting pipe, and the sealing groove is located outside the retaining ring installation groove and is installed with a sealing ring.

Further, there is a notch on the retaining ring.

Further, it also includes an externally threaded connector, the externally threaded connector has an axial through hole and the two ends are respectively provided with a first external thread and a second external thread, and the end of the connecting pipe is installed in the through hole Inside, the first external thread forms a threaded connection with the nut.

The beneficial effect of the utility model is: this product can realize the fast connection installation and disassembly of the pipe fittings by using the nuts on the connecting pipes to connect the pipe fittings, and prevent the nuts from being separated from the connected pipe fittings through the retaining ring , effectively reducing the time required for installation and disassembly of pipe fittings, and improving work efficiency.

detailed description

Referring to Fig. 1, Fig. 2 and Fig. 3, a pipe joint of the present invention includes a connecting pipe 1, the end of the outer wall of the connecting pipe 1 is provided with a retaining ring installation groove 11, and the retaining ring installing groove 11 is installed with The retaining ring 2, the outer wall end of the connecting pipe 1 is also covered with a nut 3, and the nut 3 is provided with a threaded hole 31, and the threaded hole 31 is used to connect a pipe fitting with an external thread at the end. In order to prevent the nut from 3 and the pipe fittings connected thereto fall off from the connecting pipe 1 , and one end of the threaded hole 31 is provided with a ring of protrusions 32 higher than the threads, and the inner diameter of the protrusions 32 is smaller than the outer diameter of the retaining ring 2 . This product connects the pipe fittings by fitting the nut 3 on the connecting pipe 1 shown, and prevents the nut 3 from detaching from the connected pipe fittings through the retaining ring 2, so that the quick connection installation and disassembly of the pipe fittings can be realized , effectively reducing the time required for installation and disassembly of pipe fittings, and improving work efficiency. In this embodiment, the connecting pipe 1 is a straight pipe, but according to the actual situation, as shown in Fig. 6 and Fig. 7, the connecting pipe 1 can also be an elbow pipe, a tee pipe, etc.

Referring to Fig. 1, Fig. 4 and Fig. 5, in order to prevent the liquid in the pipe from seeping out from the position of the pipe joint, the end of the outer wall of the connecting pipe 1 is also provided with a sealing groove 12, and the sealing groove 12 is located in the retaining ring installation groove 11 The outer side is equipped with sealing ring 4.

Referring to Fig. 1, since the main function of the retaining ring 2 is to prevent the nut 3 from slipping out from both ends of the connecting pipe 1, the retaining ring 2 needs to have a certain rigidity and hardness so as to prevent the retaining ring from 2 is deformed under extrusion and cannot achieve the effect of preventing the nut 3 from sliding out; but the retaining ring 2 is installed inside the retaining ring installation groove 11, in order to make the retaining ring 2 convenient and simple to realize For installation, there is a notch 21 on the retaining ring 2 .

Referring to Figure 1, Figure 4, and Figure 5, for pipe fittings with external threads at the joints of pipe fittings, the installation can be well realized through the above-mentioned components, but for pipe fittings with internal threads instead of external threads Pipe fittings cannot be connected through the above scheme, so in order to realize the connection of pipe fittings with internal threads at the pipe joints, the pipe joints also include an external threaded connector 5, and the external threaded connector 5 is provided with an axial through The hole 51 and the two ends are respectively provided with a first external thread 52 and a second external thread 53, the end of the connecting pipe 1 is installed in the through hole 51, and the first external thread 52 forms a thread with the nut 3 connect. The second external thread 53 forms a threaded connection with the internal thread of the joint of the pipe to be connected.

The above is only a preferred embodiment of the utility model, but the utility model is not limited to the above-mentioned embodiment, as long as it achieves the technical effect of the utility model by any same or similar means, it should fall into the protection scope of the utility model within.
