The hatch cover comprises a fence, a cylinder cover, a sealing assembly, a rotary ring and a locking assembly, and the cylinder cover is detachably connected to the fence; the sealing assembly comprises a sealing strip, and the sealing strip is arranged on the cylinder cover. The rotary ring is arranged on the peripheral surface of the fence in a sleeving mode and provided with a pressing piece. The locking assembly is connected with the rotary ring and used for driving the rotary ring to move relative to the fence. Wherein the fence is provided with a first position and a second position, when the rotary ring moves to the first position, the pressing piece abuts against the top end of the cylinder cover to apply pretightening force to the sealing strip so that the sealing strip can be attached to the top end of the fence, and when the rotary ring moves to the second position, the pressing piece is separated from the cylinder cover. The cylinder cover is closed, the press-fit piece on the rotary ring abuts against the top end of the cylinder cover, pretightening force can be applied to the sealing strip, sealing of the cylinder cover is guaranteed, and when the cylinder cover bears pressure reversely, due to the fact that the press-fit piece abuts against the cylinder cover, the cylinder cover can bear internal pressure and does not deform or disengage from a fence.

    本申请涉及一种舱口盖,其包括:围栏、缸盖、密封组件、回转环和锁紧组件,缸盖可拆卸地连接在围栏上;密封组件包括密封条,密封条设置于缸盖上;回转环套设于围栏外周表面,回转环上设置有压合件;锁紧组件与回转环连接,并用于驱动回转环相对于围栏运动;其中,围栏上具有第一位置和第二位置,当回转环运动至第一位置时,压合件抵持于缸盖顶端,以向密封条施加预紧力,以使密封条与围栏顶端贴合,当回转环运动至第二位置时,压合件与缸盖分离。本发明中缸盖闭合,回转环上的压合件抵持于缸盖顶端,可以向密封条施加预紧力,保证了缸盖的密封,当缸盖反向承压时,由于压合件将缸盖抵紧,使缸盖可以承受内压而不发生变形或与围栏脱开。
