Waterproof box
View Patent ↗The present invention provides a waterproof box which can improve water performance and work efficiency, and can reduce space. When washing water hits in the lower surface ( 33 h ) of first waterproof portion ( 33 ) of an upper cover ( 15 ), spay is generated. At this time, an outer surface ( 30 b ), which is formed in a tapered shape, of first waterproof portion ( 30 ) abuts on an inner surface ( 33 g ), which is formed in a tapered shape, of the first waterproof portion ( 33 ). Further, the outer surface ( 30 b ) engages with the inner surface ( 33 g ). As a result, the inlet of a minute path ( 27 ) is closed. Even if water leaks, force of the water is reduced because the water enters in a groove ( 33 b or 35 a ). The water in which force of the water is reduced falls down.
1. A waterproof box comprising:
a main body having an interior wall and a peripheral wall and non-waterproof receiving components inside of the peripheral wall;
a cover having a cover peripheral wall, the cover covering an opening formed between edges of the peripheral wall of the main body and edges of the cover peripheral wall;
a main body side waterproof structure arranged around a top end of the peripheral wall of the main body; and
a cover side waterproof structure arranged on a bottom end of the cover peripheral wall,
wherein the main body side waterproof structure is overlapped with the cover side waterproof structure so as to waterproof, causing a main body side matching surface and a cover side matching surface to oppose each other,
wherein the main body side matching surface and the cover side matching surface are formed as at least a tapered surface which are abutted and fit when the cover is moved in a direction removing the main body, and
wherein a groove is formed in between the cover peripheral wall and a third waterproof member in an outlet of a minute path.
2. The waterproof box as claimed in claim 1 , wherein rotation supporting points are arranged in the main body side waterproof structure and the cover side waterproof structure respectively so that the cover is rotatably and removably moved against the main body.
3. The waterproof box as claimed in claim 1 ,
wherein the main body side waterproof structure has a first waterproof portion arranged in an inlet of the minute path, a second waterproof portion arranged in a middle of the minute path, and a third waterproof portion arranged in an outlet of the minute path, and
wherein an outer surface of the first waterproof portion is formed into a taper shape in which distance from an inner surface of the peripheral wall becomes gradually smaller toward a bottom.
