Abstract

The invention discloses a spring-assisted hatch cover comprising a side plate, a cover plate, a locking device, a buckle, a handle, a spring, an opening positioning part, a handle stop part, and a compressing stop part. The side plate encloses cabin space. The cover plate is hinged to the top of one side of the side plate through a hinge. Filler is disposed at the part, in contact with the top of the side plate, of the cover plate. The locking device is disposed one side, far away from the hinge, of the cover plate. The buckle is disposed on one side, far away from the hinge, of the side plate and fits the locking device. The handle is disposed one side, far away from the hinge, of the side plate and connected with the buckle. One end of the spring is mounted on one side, far away from the hinge, of the side plate, and the other end of the spring is mounted at one end, far away from the hinge, of the cover plate. The opening positioning part is disposed on one side, hinged to the side plate, of the cover plate. The handle stop part is disposed on the handle. The compressing stop part is disposed at one end, locked to the side plate, of the cover plate. A weight is replaced with the spring, so that the product is more attractive in appearance, and manufacturing cost is also reduced.
