Description

Technical Field

[0001] The utility model relates to the field of pipe connectors, in particular to an external thread quick joint. Background Art

[0002] A pipe quick joint is a joint that can connect or disconnect a pipeline without tools. During the use of pipelines, due to factors such as building or road construction, the pipeline may leak or be damaged, and emergency repairs are required. Usually, a pipeline emergency repair device is used to repair the damaged part of the pipeline; the pipeline emergency repair section uses its shell and the sealing ring inside the shell to wrap the damaged part of the pipeline and then locks it to quickly achieve the purpose of leak stoppage. At this time, the pipe quick joint can be quickly installed for emergency repair without tools. Traditional metal pipe connectors are generally obtained by separately casting metal blank parts and then processed and assembled. However, some metal castings are relatively expensive, and molds need to be developed before casting, so the production cycle is relatively long. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an external thread quick joint with relatively low cost and short production cycle.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions;

[0005] An external thread quick joint includes a nut, an external thread quick joint main body, a gasket, and a sealing member. The external thread quick joint main body includes a nut connection sealing member, an external thread quick joint connecting pipe, and an external thread connecting member. One end of the external thread quick joint connecting pipe is welded with the nut connection sealing member, and the other end of the external thread quick joint connecting pipe is welded with the external thread connecting member.

[0006] Further, the welding method of the external thread quick joint connecting pipe and the nut connection sealing member is specifically laser welding, and the welding method of the external thread quick joint connecting pipe and the external thread connecting member is specifically laser welding.

[0007] Further, the materials of the nut connection sealing member, the external thread quick joint connecting pipe, and the external thread connecting member are specifically stainless steel.

[0008] The beneficial effects of the utility model are:

[0009] In the present utility model, the nut, the sealing member, the external-thread quick-connect pipe, and the external-thread connecting member are combined together by welding. Compared with the traditional casting method, the sample-making cycle of this structure and process is shorter because the mold-opening cycle is omitted. In addition, the welded pipe fittings can directly purchase the existing pipe fitting materials on the market for combined welding processing. The existing pipe fitting materials on the market are usually cheaper than the castings made by self-opening molds. Moreover, without opening a separate mold, the cost is even cheaper, showing obvious economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will briefly introduce the drawings required for the description of the embodiments or the prior art:

[0017] The following will illustrate the detailed embodiments of the present utility model with reference to the drawings.

[0018] Referring to the attached Figure 1 — Figure 2 as shown:

[0019] An external-thread quick-connect includes a nut 1, an external-thread quick-connect main body 2, a gasket 3, and a sealing member 4. The nut 2 is threadedly connected to one end of the external-thread quick-connect main body 2, and a gasket 3 and a sealing member 4 are installed between the nut 2 and the external-thread quick-connect main body 2.

[0020] Referring to the attached Figure 3 — Figure 5 as shown:

[0021] The external thread quick-connect main body 2 includes a nut connection seal 2a, an external thread quick-connect connecting pipe 2b, and an external thread connecting member 2c. One end of the external thread quick-connect connecting pipe 2b is welded with the nut connection seal 2a, and the other end of the external thread quick-connect connecting pipe 2b is welded with the external thread connecting member 2c.

[0022] In the present utility model, the materials of the nut connection seal 2a, the external thread quick-connect connecting pipe 2b, and the external thread connecting member 2c are specifically stainless steel. They are combined together by welding. Compared with the traditional casting method, the sample-making cycle of this structure and process is shorter because the mold-opening cycle is omitted. In addition, the welded pipe fittings can directly purchase the existing pipe fitting materials on the market for combined welding processing. The existing pipe fitting materials on the market are usually cheaper than the castings made by oneself through mold opening. Moreover, there is no need to open a mold separately, so the cost is cheaper, and it has obvious economic benefits.

[0023] The above is only the specific implementation manner of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantive modification of the present utility model using this concept shall fall within the scope of infringement of the protection scope of the present utility model.
