[0002] Manifold skids and manifold connectors are special pipeline transmission equipment used in oilfield drilling, cementing, fracturing and other operations. During operation, the manifold skids and manifold connectors should be installed together to form a unified channel.

[0004] However, the above patents still have the following shortcomings: when the union connection end and the threaded connection end rotate, friction will inevitably be caused to the sealing bag, and long-term use will affect the sealing effect of the sealing bag; in addition, when the first straight tube body and the second straight tube body slide, a part of the area is exposed to the outside, and dust and impurities are easy to adhere to its surface, affecting its subsequent sliding smoothness. For this reason, we propose a retractable and rotatable manifold connection structure. Utility Model Content
