Description

Technical Field

[0001] The utility model relates to the field of pipeline structures, in particular to a pipeline with a connecting structure. Background Art

[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Pipes are generally connected by flanges in pipelines. The connected pipes are fixed on the ground. During use, the pipe in the middle of the pipeline will inevitably be damaged and need to be replaced. When replacing the pipe in the middle of the pipeline, the damaged pipe should be replaced first, and then the new pipe should be stuck in the original pipe. Then a sealing ring should be set at the flange. At this time, the gap at the connection of the flange is very small, and it is difficult to place the sealing ring in the middle of the flange, which affects the installation speed. Therefore, a pipeline with a connection structure is proposed. Utility Model Content

[0003] The main purpose of the utility model is to provide a pipeline with a connecting structure, which can effectively solve the problems mentioned in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A pipeline with a connecting structure comprises a pipeline body, pipeline interfaces are provided at both ends of the pipeline body, internal threads are provided in the pipeline interfaces, a connecting mechanism is provided at the internal threads of the pipeline body, the connecting mechanism comprises an adjusting short tube connected to the pipeline body, a connecting flange is provided at one end of the adjusting short tube, a flange docking hole is opened at the edge of the connecting flange, a sealing ring sleeve is provided on the adjusting short tube, a rubber sealing ring is provided in the sealing ring sleeve, a rotating mechanism is fixedly installed on the adjusting short tube near the connecting flange, the rotating mechanism comprises a connecting ring seat fixed on the adjusting short tube, mounting through holes are provided at intervals on the connecting ring seat, a support foot sleeve is fixedly installed in the mounting through hole, and a rotating rocker is connected in the support foot sleeve.

[0006] Furthermore, an outer side of the adjusting short tube is provided with an external thread, and the adjusting short tube is connected to the pipeline body through the cooperation of the internal thread and the external thread.

[0007] Furthermore, the connecting flange is installed at the pipe interface of the pipe body through an adjusting short pipe, the sealing ring sleeve is connected to the adjusting short pipe through an external thread, and the rubber sealing ring is restricted at the connection between the adjusting short pipe and the pipe body through the sealing ring sleeve.

[0008] Furthermore, a rotating handle is fixedly mounted on one end of the rotating rocker, and a docking foot is fixedly mounted on the other end of the rotating rocker.

[0009] Furthermore, the rotating rocker is connected to the leg sleeve via a docking leg, the leg sleeve is installed on the connecting ring seat via a mounting through hole, and the rotating rocker is connected to the connecting ring seat via the cooperation between the docking leg and the leg sleeve.

[0010] Furthermore, the connection mechanism is connected to the pipeline body via an internal thread.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] After the damaged pipe is removed, the pipe body can be connected to the damaged pipe. The short adjusting tube can then be rotated inside the pipe body to move the connecting flange toward the side of the pipe body, thereby increasing the gap between the connecting flanges and making it easier for the installer to place the sealing ring in the middle of the connecting flanges. This speeds up the installation. After the sealing ring is placed in the middle of the connecting flanges, the short adjusting tube can be rotated forward to quickly connect the connecting flanges together.

[0019] like Figure 2 As shown, the connecting mechanism 5 includes an adjusting short tube 504 connected to the pipeline body 1, a connecting flange 501 is provided at one end of the adjusting short tube 504, a flange docking hole 506 is opened at the edge of the connecting flange 501, a sealing ring sleeve 502 is provided on the adjusting short tube 504, a rubber sealing ring 505 is provided in the sealing ring sleeve 502, an external thread 503 is provided on the outer side of the adjusting short tube 504, the adjusting short tube 504 is connected to the pipeline body 1 through the cooperation of the internal thread 3 and the external thread 503, the connecting flange 501 is installed at the pipeline interface 2 of the pipeline body 1 through the adjusting short tube 504, the sealing ring sleeve 502 is connected to the adjusting short tube 504 through the external thread 503, and the rubber sealing ring 505 is limited at the connection between the adjusting short tube 504 and the pipeline body 1 through the sealing ring sleeve 502.

[0020] The connecting flange 501 can be installed at both ends of the pipeline body 1 by adjusting the short tube 504. At the same time, the short tube 504 can be rotated during the installation process. After rotating the adjusting short tube 504, it will drive the connecting flange 501 to move, thereby adjusting the distance between the connecting flanges 501, which is convenient for users to install the sealing ring on the flange. Secondly, the sealing ring sleeve 502 can be tightened. After tightening the sealing ring sleeve 502, the rubber sealing ring 505 can be fixed at the connection between the adjusting short tube 504 and the pipeline body 1 to play a sealing role.

[0021] like Figure 3 As shown, the rotating mechanism 4 includes a connecting ring seat 404 fixed on the adjusting short tube 504, and the connecting ring seat 404 is provided with installation through holes 405 at intervals. A support foot sleeve 406 is fixedly installed in the installation through hole 405, and a rotating rocker 402 is connected in the support foot sleeve 406. A rotating handle 401 is fixedly installed at one end of the rotating rocker 402, and a docking support foot 403 is fixedly installed at the other end of the rotating rocker 402.
