[0028] In order to explain in detail the possible application scenarios, technical principles, specific solutions that can be implemented, and the purpose and effects of this application, the following is a detailed description of the specific embodiments listed in conjunction with the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of this application and are therefore only examples and are not intended to limit the scope of protection of this application.

[0029] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more features.

[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0031] The present invention provides a pipe welding tool to solve the problem of overly complex pipe fixing methods in related art devices.

[0032] Example 1:

[0033] See also Figure 1 and Figure 2The embodiment of the present application provides a pipe welding tool for welding a pipe fitting 5, which includes a first pipe 51 and at least one second pipe 52. The axis of the first pipe 51 and the axis of the second pipe 52 are perpendicular to each other, and one end of the second pipe 52 is connected to the pipe wall of the first pipe 51. The pipe welding tool includes a first fixing assembly 1 and a second fixing assembly 2. The first fixing assembly 1 is used to fix the first pipe 51. The second fixing assembly 2 includes a fixing bracket 22 and a connector 21. The connector 21 is detachably connected to the fixing bracket 22. The connector 21 can tightly abut and snap fit with the inner and / or outer walls of the second pipe 52. When the first pipe 51 is fixed to the first fixing assembly 1 and the second pipe 52 is fixed to the second fixing assembly 2, one end of the second pipe 52 abuts against the pipe wall of the first pipe 51.

[0034] By providing a first fixing assembly 1 to support and fix the first pipe 51, providing a fixing bracket 22 to support the connector 21, and providing the connector 21 to fix the second pipe 52, the first pipe 51 and the second pipe 52 are brought into contact, thereby facilitating welding. The pipe welding tool provided in the embodiment of the present application has a simple structure and conveniently fixes the pipe, thus resolving the problem of overly complex pipe fixing methods in related art devices.

[0035] See also Figure 1 and Figure 2 The pipe welding tool also includes a base plate 3 and a gas nozzle 4. The base plate 3 is used to carry the first fixing component 1, the second fixing component 2 and the gas nozzle 4. The base plate 3 is arranged in a rectangular plate shape. The first fixing component 1, the second fixing component 2 and the gas nozzle 4 are all arranged on the base plate 3. The gas nozzle 4 is connected to the external gas source, and the gas nozzle 4 can extend into the interior of the pipe 5. In this embodiment, a connecting pipe 53 is connected to one side of the first pipe 51, and the connecting pipe 53 is connected to the first pipe 51. The gas nozzle 4 can extend into the connecting pipe 53, so that when welding the pipe, the gas nozzle 4 can deliver protective gas to the position to be welded, thereby improving the welding quality.

[0036] See also Figure 1 and Figure 2 The first fixing component 1 is used to support and fix the first pipe 51. The first fixing component 1 includes at least one support frame 11, which is fixedly connected to the base plate 3. A support groove 12 for accommodating and fixing the first pipe 51 is provided at the top of the support frame 11. The support groove 12 is a through groove. When the first pipe 51 is accommodated in the support groove 12, the tube wall of the first pipe 51 fits tightly with the groove wall of the support groove 12. In this embodiment, the number of support frames 11 is set to two, and the two support frames 11 are spaced apart along the length direction of the base plate 3.

[0037] See also Figure 2 and Figure 3The connecting member 21 is used to support and fix the second pipe 52. The connecting member 21 includes a fixing portion 211 and a connecting portion 212. The fixing portion 211 and the connecting portion 212 are both cylindrical. The connecting portion 212 is fixedly connected to one end of the fixing portion 211. When the second pipe 52 is fixed to the connecting member 21, the end of the connecting portion 212 away from the fixing portion 211 extends into the second pipe 52 and engages with the inner wall surface of the second pipe 52. The fixed bracket 22 includes a support plate 221 and two support columns 222. The two support columns 222 are both fixedly connected to the bottom plate 3, and the two support columns 222 are spaced apart along the length direction of the bottom plate 3. The support plate 221 is arranged horizontally, one end of the support plate 221 is fixedly connected to one of the support columns 222, and the other end is fixedly connected to the other support column 222. A support hole 223 is provided on the support plate 221.

[0038] See also Figure 2 and Figure 3 In this embodiment, the number of connectors 21 is set to multiple, and the number of support holes 223 is also set to multiple. The connectors 21 and support holes 223 are arranged in a one-to-one correspondence. When the connector 21 is set on the fixing bracket 22, the fixing portion 211 abuts the top layer of the support plate 221, and the connector 212 is inserted into the corresponding support hole 223. In addition, the side wall of the connector 212 is provided with a vent groove 213. The vent groove 213 is provided along the length of the connector 212. In this embodiment, the number of vent grooves 213 is set to four, and the four vent grooves 213 are provided at equal intervals along the circumference of the connector 212. By providing the vent grooves 213 on the connector 212, when welding the closed pipe fitting, the protective gas introduced into the pipeline can be discharged from the pipe fitting through the vent grooves 213. This reduces the occurrence of solder having difficulty penetrating the gap between the first pipe 51 and the second pipe 52 during welding due to the continuous introduction of protective gas into the pipe fitting, which creates a high-pressure atmosphere in the pipeline, thereby improving the welding quality.

[0039] Example 2:

[0040] See also Figure 4 The difference between this embodiment and embodiment 1 lies in the connection member 21 . In this embodiment, a vent hole 214 is provided on the connection member 21 , and the vent hole 214 passes through the fixing portion 211 and the connection portion 212 .

[0041] The opening of the vent hole 214 allows the protective gas introduced into the pipe to be discharged from the vent hole 214. When the second pipe 52 is completely sleeved on the connecting portion 212, a pressure relief channel is provided for the protective gas, thereby improving the welding quality.

[0042] Example 3:

[0043] See also Figure 5This embodiment differs from Example 1 in that the connector 21 is different. In this embodiment, a fixing groove 215 is defined at the end of the connecting portion 212 away from the fixing portion 211, into which one end of the second tube 52 extends. After the second tube 52 extends into the fixing groove 215, the outer wall of the second tube 52 tightly abuts the wall of the fixing groove 215 and engages with it. The connecting portion 212 is inserted into the corresponding support hole 223 and tightly abuts the wall of the support hole 223 and the side wall of the connecting portion 212. Furthermore, a vent hole 214 is defined in the connecting portion 21, which passes through the fixing portion 211 and the connecting portion 212.

[0044] By providing a fixing groove 215 for fixing the second pipe 52 on the connecting portion 212 , a better effect can be achieved when providing support for the second pipe 52 with a small radius, thereby facilitating the fixing of the second pipe 52 .

[0045] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
