Waterproof box
View Patent ↗The present invention is to provide a waterproof box capable of improving waterproof performance and workability, and space-saving. When high-pressure washing is performed, washing water injected toward the waterproof box hits a peripheral wall of a box main body, and then washing water is increased along the peripheral wall. Since the increased washing water hits a lower surface of a first waterproof portion of a main body side waterproof structure, some force of the water is reduced. Furthermore, a part of the increase washing water passes through a space arranged inside of a wall upward.
1. A waterproof box comprising:
a box main body having a peripheral wall and receiving components inside of the peripheral wall, the components disliking water;
a cover having a cover peripheral wall and covering an opening of edges of the peripheral wall of the box main body;
a main body side waterproof structure arranged in the edges of the peripheral wall of the box main body; and
a cover side waterproof structure arranged in edges of cover peripheral wall of the cover,
wherein the main body side waterproof structure is overlapped with the cover side waterproof structure so as to waterproof, and
wherein a wall, which is located outside an overlapped portion and opposed to an outer surface of the peripheral wall at a predetermined space, is provided as a part of the cover side waterproof structure with respect to a horizontal direction and separated from the main body side waterproof structure,
wherein rotation supporting points are arranged in the main body side waterproof structure and the cover side waterproof structure respectively so as to rotatably and removably move the cover against the box main body,
wherein the rotation supporting point of the cover side waterproof structure comprises a through hole and a pair of protective walls which are formed on both sides of the through hole and formed into a rib shape,
wherein the main body side waterproof structure comprises a first waterproof portion arranged as an inlet of a micro passage and a second waterproof portion arranged as an outlet of the micro passage,
wherein the wall is formed at an outermost position of the protective walls, and a lower wall of the first waterproof portion is projected toward the wall, and
wherein a space is formed between the wall and an outer surface of the first waterproof portion.
2. The waterproof box as claimed in claim 1 , further comprising
a main body side matching surface of the main body side waterproof structure, a cover side matching surface of the cover side waterproof structure, and a micro passage generated in a space between the main body side matching surface and the cover side matching surface,
wherein the main body side matching surface and the cover side matching surface are opposed each other by overlapping, and
wherein an inlet of the micro passage is arranged so that the wall of the cover side waterproof structure is positioned in front of the inlet at an interval.
3. The waterproof box as claimed in claim 2 , wherein the inlet of the micro passage is arranged outward in a direction perpendicular to the outer surface of the peripheral wall of the box main body.
4. The waterproof box as claimed in claim 1 , wherein
an outer surface of the first waterproof portion is formed into a taper shape in which a distance from an inner surface of the peripheral wall becomes gradually small toward bottom.
5. The waterproof box as claimed in claim 4 , wherein
the cover side waterproof structure comprises a first waterproof portion arranged as an inlet of the micro passage, a second waterproof portion arranged as an outlet of the micro passage, and is formed which wall is in a skirt shape opening outward.
6. The waterproof box as claimed in claim 5 , wherein
the second waterproof portion of the cover side waterproof structure comprises a groove opening in a surface opposed to an upper surface of the second waterproof portion of the main body side waterproof structure; and comprising a space formed by an upper surface of the second waterproof portion of the main body side waterproof structure, an inner surface, an outer surface, and an innermost surface of the second waterproof portion of the cover side waterproof structure.
7. The waterproof box as claimed in claim 6 , wherein
a first outlet reference which is a position of an intersection of an opening of the groove with the inner surface of the second waterproof portion of the cover side waterproof structure; and a second outlet reference which is a position of an intersection of an inner surface of the peripheral wall with the upper surface of the second waterproof portion of the main body side waterproof structure; are arranged on a same plane.
