Abstract
The utility model discloses a water and dust proof structure of a case, which comprises a case body and a case cover plate. The water and dust proof structure is characterized in that a cutting opening is arranged on the case body; the length and width of the cutting opening are smaller than those of the case cover plate; a metal frame which is installed at the outer edge of the cutting opening is formed into a whole with the case body; and an annular groove is mounted between the case body and the outer edge of the metal frame. Because a projecting groove structure is added at the position of the cutting opening of the case body, water and dust can be successfully collected inside the groove and guided to two sides of the groove when the case body meets water and dust, thereby leading the case to achieve an IP67 grade water and dust proof effect.
Description
Technical field
The utility model relates to the improvement to casing structure.
Background technology
In the same industry, what cabinet was generally taked is simply to cut opening, and opening surface becomes the design on plane, adds sponge or rubber seal again on the cabinet cover plate, and as shown in Figure 1, this structure can only reach low-grade water proof and dust proof effect.
The utility model content
The purpose of this utility model is, proposes a kind of new cabinet hatch frame, makes that the water proof and dust proof effect is better.
To achieve these goals, the technical solution adopted in the utility model is as follows:
The waterproof and dustproof structure of cabinet, comprise machine case body and cabinet cover plate, have one on the machine case body and cut mouth open, the length of cutting opening and wide all less than the cabinet cover plate, cutting opening outer is provided with a metal frame, metal frame and machine case body are one-body molded, are provided with a circle groove between metal frame outer and machine case body.
As improvement to such scheme, the length of the length of metal frame and wide and cabinet cover plate and wide identical.
As improvement to such scheme, have the hole in cabinet cover plate inner surface edge, the relevant position also has the hole on the metal frame.
As the improvement to such scheme, cabinet cover plate inner surface edge is provided with a circle sponge or a rubber seal.
The beneficial effects of the utility model are: added outstanding groove structure at cabinet cutting opening part, when cabinet is met water chance dirt, groove can success water and dirt are accumulated in the groove, and it is derived to both sides, make cabinet reach the waterproof and dustproof effect of IP67 grade.
Description of drawings
Fig. 1 is a prior art casing structure schematic diagram;
Fig. 2 is the utility model casing structure schematic diagram;
Fig. 3 is the utility model casing structure lateral plan.
Embodiment
The casing structure of water proof and dust proof referring to Fig. 2, Fig. 3, comprises machine case body 1, rectangular cabinet cover plate 2, has cutting opening 3 on the machine case body 1, also be rectangle, but it is grown and the wide length that all is slightly less than the cabinet cover plate and wide.Along the periphery of cutting opening, set up a metal frame 4, metal frame 4 is one-body molded with machine case body 1, has a circle groove 5 between metal frame outer and machine case body.When cabinet is met water when meeting dirt, what groove can success accumulates in water and dirt in the groove, and it is derived to both sides.
Be provided with some borings 6 in cabinet cover plate inner surface edge, the relevant position also has boring 7 on the metal frame.Cover plate with the machine case body closure after, can utilize boring with the cover plate fixing seal.
