The invention relates to a watertight hatch cover, in particular to a quick open and close pressure proof watertight hatch cover and belongs to the technical field of ship outfitting. The quick open and close pressure proof watertight hatch cover comprises a coaming plate, a lower base plate, a lock catch device, an upper base plate, a watertight rubber strip, a cover plate, a hand wheel transmission mechanism, linkage compression devices, inclined wedges and a spring hinge device; the upper end of the lower base plate supports the upper base plate; the coaming plate is welded to the lower end of the lower base plate; the cover plate is welded to the upper end of the upper base plate; one sides of the lower base plate and the upper base plate are provided with the spring hinge device; the other sides of the lower base plate and the upper base plate are provided with the lock catch device; the hand wheel transmission mechanism is welded to the center of the cover plate. According to the quick open and close pressure proof watertight hatch cover, the hatch is quickly opened or closed through the central hand wheel transmission mechanism and the spring hinge device, the opening and closing are rapid and convenient, fixation of an insertion pin with a tongue is safe and reliable, the watertight experimental pressure achieves 0.5MPa, water is effectively obstructed from expanding to an engine room and other cabins at inlets and outlets, and accordingly normal operation of machines in the cabin is guaranteed and the safe escape of the personnel is guaranteed and the property loss is reduced.
