According to the hatch cover structure, a concave embedding groove is formed in a hatch of a deck through a base plate and a bottom frame, so that the hatch cover is embedded in the embedding groove and is flush with the surface of the deck, the space of the deck is prevented from being occupied, and passing smoothness and safety are prevented from being affected; one side of the hatch cover is hinged to the hinge seat, and the hinge hole is in an inclined oval shape, so that the hatch cover can be opened to 90 degrees or above, and people or goods can pass through the hatch cover conveniently; an outer handle and an inner handle are installed at the inner end and the outer end of a rotatable main shaft on the hatch cover respectively, a locking rod is further hinged to the main shaft, a limiting plate and a surrounding plate which are opposite are installed on the hatch cover and the bottom frame, the locking rod penetrates through the limiting plate, rotates along with the main shaft to be inserted into or retreat from a surrounding plate hole of the surrounding plate, and the locking rod abuts against an inclined wedge block inclined in the circumferential direction after penetrating through the surrounding plate. Therefore, the hatch cover is locked. The hatch cover is simple in structure and convenient and fast to operate, can effectively seal the hatch cover, and can be perfectly hidden in a deck, so that deck space occupation and passage obstruction are avoided.
一种舱口盖结构,甲板的舱口处通过垫板和底框设置内凹的嵌入槽,使舱盖内嵌于嵌入槽内并与甲板表面平齐,避免占用甲板空间和影响通行的顺畅性、安全性;舱盖的一侧与铰接座铰接,且铰孔为倾斜的椭圆形,使舱盖可以打开至90度以上,以便人员或货物通行;舱盖上可转动的主轴内、外两端分别安装外把手和内把手,主轴上还铰接有锁紧杆,舱盖和底框上安装相对的限位板和围板,锁紧杆穿过限位板并随主轴转动而插入或退出围板的围板孔,锁紧杆穿过围板后与沿周向倾斜的斜楔块相抵,从而将舱盖锁紧。该种舱口盖的结构简单,操作方便、快捷,能够有效实现舱盖的密封,并可以完美隐藏于甲板内,从而避免占用甲板空间和造成通行阻碍。
