Abstract
The utility model discloses a manhole cover. The manhole cover comprises a fixing hinge base, a rotation hinge plate hinged to the fixing hinge base through a hinge pin, and a manhole cover plate fixed to the rotation hinge plate. According to the manhole cover, when the manhole cover plate is opened or closed, it is not needed to move and place the whole bulky manhole cover plate, and it is enough to rotate the manhole cover plate around the hinge pin after the manhole cover plate disengages from a double-screw bolt. Labor is saved in the using process, and the manhole cover can be used at high altitude or under the environment where it is hard for workers to exert strength; the storage space of the manhole cover plate is small, and the manhole cover is suitable for being used in narrow space. The manhole cover plate is not prone to being lost or damaged in the constructing or using process through the hinge type design. The manhole cover is easy to manufacture, convenient to use and easy to popularize.
