All-metal box body for electric appliance

Abstract

The invention discloses an all-metal box body for an electric appliance. The all-metal box body for the electric appliance is mainly formed by assembling an upper cover plate, a lower cover plate anda middle box frame which are made from metal, wherein the middle box frame is a quadrilateral hollow structure encircled by middle side plates, at least one air inlet port and an air outlet port are formed in the middle side plate of at least one side of the middle box frame, and the upper edge and the lower edge of the middle box frame are connected with the upper cover plate and the lower coverplate through fasteners separately; and the shapes of the upper cover plate and the lower cover plate are squares corresponding to the upper part and the lower part of the middle box frame separately,each square is mainly composed of a cover plate surface and a peripheral outer turned edge, at least four screw holes used for assembling the middle box frame are formed in the cover plate surface ofthe upper cover plate, four square grooves used for assembling the middle box frame are formed in the cover plate surface of the lower cover plate, inner-turned-edge upper screw holes corresponding to the screw holes are formed in the upper edge of the middle box frame, and square sockets corresponding to the square grooves are formed in the lower edge of the middle box frame. The all-metal box body for the electric appliance has the characteristics of being reasonable in structure, high in heat dissipation, safe and fireproof, and the like.

Description

technical field [0001] The invention relates to a metal electrical box, in particular to an all-metal box made by assembling, and belongs to the technical field of electrical box shells. Background technique [0002] The main body of heaters, ventilation fans, etc. currently on the market are basically made of metal or plastic. In order to reduce manufacturing costs, most of them are made of plastic, but generally plastic is easily deformed, melted or even affected by high temperature. It may catch fire and affect the safe use of electrical products, and the plastic box is easy to age after a long time of use, and there is a greater safety hazard; for a small number of metal boxes, most of them are made of iron boxes, which are welded into an overall shape and are universal. Poor sex. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to provide a reasonable structure, high strength, solid, heat-re...
