The invention relates to a quick and labor-saving opening and closing handle mechanism for a pressure-resistant hatch cover, comprising a pressure-resistant hatch cover. A connecting shaft is vertically mounted in the middle of the pressure-resistant hatch cover. A hand wheel is installed at the top of the connecting shaft and comprises a hand wheel body and a hand wheel ring. The hand wheel bodyis of a columnar structure matched with the top of the connecting shaft. A plurality of telescopic assemblies extending outwards and penetrating through the hand wheel ring are evenly distributed in the circumferential direction of the hand wheel body, and lock catch assemblies controlling the telescopic assemblies to extend or retract are installed in the telescopic assemblies respectively. The acting force arm of the hand wheel is prolonged, operation force is reduced, the hatch cover opening speed is increased, and danger is reduced; different lengths and section numbers can be selected forthe telescopic assemblies according to different working conditions, and the application range is wide; a sealing cover can reduce corrosion of seawater to the telescopic assemblies and the lock catch assemblies, and the requirement for material performance is lowered; the telescopic assemblies do not extend outwards, so that the possibility of hooking accidents is reduced, and the operation safety is ensured; and the handle mechanism is low in manufacturing cost, reliable in performance and capable of being matched with other hatch covers.

    本发明涉及一种耐压舱口盖快速省力启闭手柄机构,包括耐压舱口盖,耐压舱口盖的中部垂直安装连接轴,连接轴的顶部安装手轮,手轮包括手轮体和手轮环,手轮体为与连接轴顶部配合的柱状结构,沿手轮体周向均布若干个向外延伸并穿过手轮环的伸缩组件,各伸缩组件内部分别安装控制伸缩组件伸长或缩短的锁扣组件。本发明延长了手轮作用力臂,降低操作用力,加快舱口盖开启速度,降低危险;伸缩组件可根据不同的作业工况选择不同长度和段数,应用范围广;密封盖能减少海水对伸缩组件和锁扣组件的腐蚀,降低材料性能要求;伸缩组件无外伸现象,减少发生钩挂事故的可能性,保证运行安全;本发明制造成本低廉,性能可靠,也可适配其他舱口盖。
