PURPOSE:To prevent a cover from dropping and opening, and safely and easily open and shut the cover, by installing an engaging metal which engages with the edge of a casing when the cover is opened. CONSTITUTION:One side of a cover 2 is fixed to the bottom surface of a casing 1, so as to revolve, open and shut via a hinge 5 installed on one side of the bottom surface of a casing 1. The other end of the cover 2 is fixed to the edge 1A of the casing 1 by using a setscrew 3. An engaging metal 4 of a spring plate whose tip is bent in a hook type is fixed on the inner side of the cover 2. When the cover 2 falls down by a specified distance B, the tip of the engaging metal 4 which is bent in the hook type is caught by the edge 1A of the casing 1, so that the cover 2 is prevented from dropping and opening. When the setscrew 3 is removed, the hook part of the engaging metal 4 is caught by the edge 1A, so that engagement is released and the cover 2 can be opened by pressing and bending the engaging metal 4 toward the hinge 5. When the cover 2 is shut, the engaging metal is bent by the edge 1A of the cabinet 1, and the hook part overcomes the edge 1A, thereby preventing the cover 2 from dropping and opening. |
