[0002] In mineral resource extraction operations, transportation pipelines are key facilities for the efficient transfer of resources from the extraction point to the processing point or storage point. Whether it is coal, metal ore or oil and gas, traditional oil pipelines are inconvenient to position during installation, are prone to misalignment and leakage during installation, and have low installation efficiency.
[0003] The prior art patent application with publication number CN211693959U discloses a connection structure for an oil extraction and transportation pipeline, including a first connecting pipe, a stirring chamber, a second connecting pipe, a stirring motor, a heat insulation layer, and an anti-corrosion layer. The first connecting pipe is connected to the second connecting pipe, and the second connecting pipe is connected to the first connecting pipe through a flange joint. The flange joint has external and internal threads on its outer side, and is connected through the internal and external threads. The flange joint further limits the connection. A heat insulation layer is provided to keep the oil warm, and an anti-corrosion layer is provided to further protect the connecting pipe from excessively low temperature inside the connecting pipe and oil corrosion of the pipeline.
[0004] However, in the aforementioned prior art, the sealing between pipes is poor, which affects the normal operation of the transportation pipeline and increases cost losses. Utility Model Content

[0011] This utility model discloses a connection structure for a mining and transportation pipeline. In use, the first and second connecting seats are first fixed to the corresponding first and second connecting pipes using a threaded screw mechanism. The pin ring is then aligned with the mounting groove and moved to the left. At this time, the pressure ring compresses the spring, causing the spring to store elastic potential energy.
