Abstract
The utility model discloses a dustproof and anti-moisture electric meter box which comprises a box body and a box cover. The box cover is provided with a visible window on which a dustproof board is arranged. The technical solution of the dustproof and anti-moisture electric meter box is characterized in that: the dustproof board is hinged with the box cover; the hinging part between the dustproof board and the box cover is provided with a first elastic member; and the box cover is provided with an elastic opening/closing device for matching with the dustproof board. When the dustproof and anti-moisture electric meter box is not in use, the dustproof board overcomes the elastic force of the first elastic member through the elastic opening/closing device for keeping closed, shielding the visible window, preventing dust entering into the box, and preventing dust accumulation, breakage, aging color changing, etc. on the visible window which is made of glass or plastic. When use of the dustproof and anti-moisture electric meter box is required, the dustproof board is opened through the elastic opening/closing device, and the first elastic member releases accumulated elastic potential energy so that the dustproof board is opened automatically. Furthermore manual keeping for the dustproof board open is not required and the open state is kept, thereby facilitating electric meter data reading and recording by the user and electric meter data reading personnel. After recording is finished, just through closing the dustproof board to position, the dustproof board is kept to a closed state under function of the elastic opening/closing device, thereby facilitating use.
