The invention discloses a easily-opened watertight hatch cover, and belongs to the technical field of ship hatch covers. The watertight hatch cover comprises a cover frame installed on a watertight hatch in an embedded mode and a cover plate hinged to the cover frame through a hinge, a matched rubber sealing ring is fixedly installed on the lower portion of the cover plate and the inner ring of the cover frame, rotatable pressing switches are arranged at the four corners of the cover plate, and a pull ring is arranged on the side, away from the hinge, of the cover plate. The hatch cover further comprises a zipper mechanism used for driving the cover plate to rotate. The zipper mechanism is additionally arranged on the cover frame, and the pull ring can be pulled by rotating the handle of the zipper mechanism so that the cover plate is opened around the hinge, and a situation that the cover plate is difficult to open directly due to a large internal and external pressure difference of the watertight hatch cover is avoided.
