Abstract

The invention provides a hatch cover with a concealed type hand-operated device and belongs to the field of ship equipment. The problem of inconvenience in entering or coming out of an existing hatch is solved. The hatch cover with the concealed type hand-operated device comprises a hatch defined by a front surrounding plate, a rear surrounding plate, a left surrounding plate and a right surrounding plate. The hatch cover further comprises a cover plate hinged to the top end of the rear surrounding plate through a hinged shaft and further comprises the hand-operated device. The hand-operated device comprises an arc-shaped hand-operated rod, the left surrounding plate is provided with an arc-shaped hole, the hole wall of the arc-shaped hole is deepened to be provided with a sliding hole, a blocking edge is formed at an orifice of the arc-shaped hole through the sliding hole, one end of the hand-operated rod is fixed to the bottom surface of the cover plate, the other end of the hand-operated rod is provided with a sliding block, and the sliding block is placed in the sliding hole and can cause the cover plate to cover the hatch around the hinged shaft, the whole hand-operated rod is placed in the arc-shaped hole, the cover plate can also be opened around the hinged shaft, and the sliding block is matched with the sliding hole to slide, so that the hand-operated rod extends out of the arc-shaped hole. Through the arrangement of the hand-operated rod, the hatch cover is convenient to use, and the influence of the hand-operated rod can be avoided on the conditions that the cover plate is closed.

Description
