Abstract

A box and cover combination comprises a box and a cover. The box includes an opening, and a hole is defined in each of two opposed sides defining the opening of the box. The cover includes a peripheral edge in an underside thereof. The peripheral edge includes two opposed engaging portions each having an engaging face. An engaging hole is defined in each engaging face. Two positioning plates each have an end pivotally connected to an associated one of the engaging portions and include an engaging member. When the cover is attached to the box, each engaging face of the cover is located in the opening of the box, and each positioning plate is located outside the box. The engaging member of each positioning plate is extendible through an associated hole of the box into the engaging hole of an associated engaging face.
