[0004] In response to the relevant content in the above, it is believed that the following technical defects exist: when welding the tube-insertion welding tube to the hollow tube, because the wall of the hollow tube is thinner, when an error occurs in the welding when using the welding tool, the welding head of the welding tool will cause the wall of the hollow tube to be welded through, causing the hollow tube to be unable to continue to be used, delaying the overall progress of the welding work. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art that when a pipe-insertion welding pipe is welded to a hollow pipe, because the wall of the hollow pipe is relatively thin, when an error occurs in welding using a welding tool, the welding head of the welding tool may cause the wall of the hollow pipe to be welded through, causing the hollow pipe to be unable to continue to be used, thereby delaying the overall progress of the welding work.

[0006] To solve the above technical problems, the utility model provides a pipe-inserted welding pipe, comprising: a pipe-inserted welding pipe body, an arc surface of the pipe-inserted welding pipe body is provided with an adjusting device, the adjusting device comprises a connecting ring, the connecting ring is slidably connected to the pipe-inserted welding pipe body, the inner wall of the connecting ring is rotatably connected with a rotating ring, one end of the arc surface of the rotating ring is fixedly connected with a fixing rod, the end of the fixing rod away from the rotating ring is fixedly connected with a connecting plate, a welding groove is provided on the side of the connecting plate, a connecting block is fixedly connected with a connecting block on the inner wall of the connecting block is slidably connected with an adjusting rod, the end of the adjusting rod close to the pipe-inserted welding pipe body is fixedly connected with an abutment plate, the arc surface of the adjusting rod is sleeved with a spring, and the two ends of the spring are respectively fixedly connected to the connecting block and the adjusting rod.

[0007] The effect achieved by the above components is: the pipe insert welding pipe body is sleeved on the surface of the hollow pipe, and the pipe insert welding pipe body can be welded to the surface of the hollow pipe by a welding tool. However, the wall of the hollow pipe is thin. When the pipe insert welding pipe body is welded to the surface of the hollow pipe by a welding tool, welding errors may easily cause the wall of the hollow pipe to be welded through, resulting in the inability to continue to use the hollow pipe. When it is necessary to weld the pipe insert welding pipe body to the hollow pipe, first pull the adjusting rod toward the end close to the spring, and the movement of the adjusting rod will drive the abutment plate to move, and then the pipe insert welding pipe body is welded to the surface of the hollow pipe. The pipe body is connected to the hollow pipe. After adjusting the welding position, the adjusting rod is loosened on the hollow pipe. The spring will drive the abutment plate to abut against the pipe plug welding pipe body through the adjusting rod, so that the connecting ring can be temporarily fixed on the pipe plug welding pipe body through the abutment plate. The welding head of the welding tool is connected to the welding groove, and the rotating ring can be rotated inside the connecting ring to drive the welding groove to move around the welding position. The welding groove can control the distance of the welding head well, thereby preventing the welding tool from welding through the hollow pipe.

[0008] Preferably, a protective ring is fixedly connected to the inner wall of the welding groove, and the protective ring is made of titanium alloy.

[0010] Preferably, a friction pad is fixedly connected to one side of the abutment plate close to the pipe body for pipe insertion welding, and the size of the friction pad is the same as that of the abutment plate.

[0011] The effect achieved by the above components is that when the abutment plate is used to contact the pipe body, the friction pad installed on the abutment plate can increase the friction between the abutment plate and the pipe body, thereby improving the stability of the connection between the abutment plate and the pipe body.

[0012] Preferably, the arc surface of the adjusting rod is rotatably connected with a pull ring.

[0013] The effect achieved by the above components is that when the adjusting rod needs to be pulled, the pull ring installed on the adjusting rod can increase the speed of pulling the adjusting rod, and the pull ring can increase the speed of pulling the adjusting rod.

[0014] Preferably, an auxiliary device is provided on the side of the pipe plug welding pipe body away from the adjusting device, and the auxiliary device includes a connecting ring, which is slidably connected to the pipe plug welding pipe body, and a fixing ring is fixedly connected to the side of the connecting ring away from the pipe plug welding pipe body, and both ends of the fixing ring are fixedly connected to support blocks, and a screw rod is slidably penetrated through the inner walls of the two support blocks, and a threaded ring is threadedly connected to one end of the arc surface of the screw rod.

[0015] The effect achieved by the above components is: the pipe insert welding pipe body is sleeved on the surface of the hollow pipe, and the pipe insert welding pipe body can be welded to the hollow pipe by using a welding tool. However, during the welding process, when the inner wall size of the pipe insert welding pipe body is large, the pipe insert welding pipe body will slide in the hollow pipe body, and the worker needs to free up one hand to press the pipe insert welding pipe body during welding. However, the worker can only operate the welding tool with one hand to weld the pipe insert welding pipe body to the hollow pipe, which also leads to poor welding effect of welding the pipe insert welding pipe body. Looseness will occur between the main body and the hollow tube. When the tube plug welding tube body needs to be welded to the surface of the hollow tube, the connecting ring is first brought into contact with the surface of the tube plug welding tube body, and then the hollow tube is inserted into the tube plug welding tube body. At this time, the fixing ring will come into contact with the hollow tube, and a screw rod is inserted into the two support blocks, and then the threaded ring is used to connect the screw rod, so that the threaded ring can be rotated on the screw rod to fix the fixing ring on the hollow tube, and the tube plug welding tube body can be temporarily fixed on the hollow tube to avoid the tube plug welding tube body sliding on the surface of the hollow tube during welding.

[0016] Preferably, the arc surface of the threaded ring is provided with a plurality of anti-skid grooves, and the anti-skid grooves are evenly distributed on the arc surface of the threaded ring.

[0017] The effect achieved by the above components is that when the threaded ring is rotated on the screw, the anti-slip groove provided on the screw can increase the friction between the worker's hand and the screw, thereby improving the efficiency of the threaded ring rotating on the screw.

[0018] Preferably, one end of the screw rod is fixedly connected to a guide block, and the cross-section of the guide block is arc-shaped.

[0019] The effect achieved by the above components is that when the screw rod is used to connect with the support block, the guide block installed on the screw rod can increase the speed of connecting the support block and the screw rod, thereby improving the connection efficiency.

[0034] The working principle of a pipe insert welding pipe provided by the utility model is as follows: when it is necessary to weld the pipe insert welding pipe body 1 to the hollow pipe, first pull the adjusting rod 207 toward the end close to the spring 212, the movement of the adjusting rod 207 will drive the abutment plate 208 to move, and then connect the pipe insert welding pipe body 1 with the hollow pipe, after adjusting the welding position, loosen the adjusting rod 207 on the hollow pipe, the spring 212 will drive the abutment plate 208 to abut against the pipe insert welding pipe body 1 through the adjusting rod 207, so that the connecting ring 201 can be temporarily fixed on the pipe insert welding pipe body 1 through the abutment plate 208, and the welding head of the welding tool is connected to the welding groove 205, and the rotating ring 202 can be rotated inside the connecting ring 201 to drive the welding groove 205 to move around the welding position. The welding groove 205 can well control the distance of the welding head, thereby preventing the welding tool from welding through the hollow tube. When the welding tool is used to perform welding through the welding groove 205, the protective ring 209 installed on the welding groove 205 can protect the surface of the welding groove 205 to prevent the welding tool from causing damage to the welding groove 205. When the abutment plate 208 is used to contact the pipe plug welding pipe body 1, the friction pad 210 installed on the abutment plate 208 can increase the friction between the abutment plate 208 and the pipe plug welding pipe body 1, and improve the stability of the connection between the abutment plate 208 and the pipe plug welding pipe.
