The invention provides a saturated diving pressurization and decompression cabin screwing door structure. The structure comprises a connecting cabin door barrel and an arch door cover arranged on an opening of the connecting cabin door barrel, wherein the arch door cover is opened and closed on the opening of the connecting cabin door barrel, and a pressing rotating ring is arranged on the openingof the connecting cabin door barrel; the pressing rotating ring is arranged on the opening connected with the cabin door cylinder body in a sleeving mode, and the pressing rotating ring is fixed in the clamping groove through the clamping ring to conduct rotating limiting on the pressing rotating ring; besides, a first wedge-shaped block is arranged on the inner side face of the pressing rotatingring, a second wedge-shaped block is arranged on the periphery of the arch-shaped door cover, and when the pressing rotating ring is rotated, the first wedge-shaped block and the second wedge-shapedblock extrude each other through a contact inclined face, so the arch-shaped door cover is pressed towards the joint face connected with the cabin door barrel to form sealing; the sealing surface is high in pressing strength, remarkable in sealing effect, easy to operate and not prone to damage, technical requirements are met, and the time and labor cost for disassembling the hatch cover are reduced.

    本发明提供一种饱和潜水加减压舱旋紧门结构,包括连接舱门筒体和设置在连接舱门筒体的开口上的拱形门盖,拱形门盖在连接舱门筒体的开口上开关,所述连接舱门筒体的开口上设有压紧转环;所述压紧转环套设于连接舱门筒体的开口上,压紧转环通过卡环固定在卡槽中对压紧转环进行旋转限位;此外,压紧转环的内侧面设有第一楔形块,所述拱形门盖的外围设有第二楔形块,旋转压紧转环时第一楔形块对第二楔形块通过接触斜面相互挤压,使拱形门盖向连接舱门筒体的接合面压紧形成密封。本发明密封面压紧强度大、密封效果显著,同时操作简单,不易损坏,满足技术要求,减少拆卸舱盖的时间和人工成本。
