Innovative frame with a hinged cover

Abstract

A novel frame with a hinged cover, characterized in that it comprises four frames connected to form a rectangular main frame, wherein at least one edge of the four frames is provided with a hinged cover component; wherein the hinged cover component comprises: a main body section of the hinged cover; an edge section of the hinged cover which can be rotated about the main body section of the hinged cover; an arc-shaped elastic piece, wherein one arc-shaped end of the arc-shaped elastic piece is clamped in the main body section of the hinged cover and the other arc-shaped end of the arc-shaped elastic piece is clamped in the edge section of the hinged cover, and wherein the elastic force generated by the arc of the arc-shaped elastic piece acts on the main body section of the hinged cover and the edge section of the hinged cover.
