The invention provides a novel tube structure of a prestress ultrahigh-pressure wire winding container. By changing the gradient of the end face of a tube, the pretightening height of a winding layeris greater than the height of a pressure-bearing surface of the inner wall of an inner tube. Under the condition that the volumes and the inner diameters of the container and the tube are fixed, a setof flat end face structure and angled end face structure models with different dimension parameters are obtained through a tube thickness and steel wire layer number adjustment and optimization trialcalculation method. ANSYS finite element modeling software is used for conducting simulation on different structures. The simulation result shows that to meet the same bearing requirements, an angledend face structure is adopted to replace a flat end face structure; compared with the flat end face, both the inner tube thickness and the steel wire layer number required for pressure bearing can bereduced, and the total mass reduction range of steel wire layers and the tube is about within 10.01%-17.77%. The changed angled end face tube structure adopts a triangular gasket and hollow metal O-ring combined hard seal and soft seal sealing structure and can both bear high pressure and ensure the good sealing performance.
