Abstract
The utility model provides an LED display screen with an insect-proofing structure, which is provided with a structure capable of preventing crawl insects of cockroaches from entering an LED box to avoid damages and unfavorable effects of crawl insects on boxes. The LED display screen comprises a box, a fan is arranged on the box, a right-angle elbow pipe is arranged at an air outlet of the fan, one end of the right-angle elbow pipe is connected to the air outlet, and the other outlet is arranged downward; a layer of inner sleeve with a smooth surface is arranged on the inner wall of one downward section of the elbow pipe; and an air inlet is arranged on the box and under the fan, and a shield with a net is arranged at an air inlet. The LED display screen with the insect-proofing structure has the advantages of being capable of effectively preventing crawl insects of cockroaches from entering the box, preventing the crawl insects from gnawing components on circuit boards in the box, preventing dead bodies of crawl insects from accumulating in the box, and improving radiating environment of the LED.
Description
Technical field
The utility model relates to a kind of LED display.
Background technology
LED display is formed by box body splicing.Because the LED thermal value is bigger, and can not in hot environment, work, thus at the back side of casing fan need be set, to strengthen heat radiation.
All there is this insect in the very suitable cockroach breeding of China's weather existence in the office space of various buildingss.Cockroach is liked weak thermal source, by it electromagnetic heat source, circuit board thermal source is had a passion for, and therefore, the LED casing of fan is installed, and becomes the place of living away from home of cockroach easily.Cockroach can climb into the LED casing along the inlet of fan, within it breeding.A large amount of cockroaches can damage electrical equipment in casing, and dead cockroach in casing, after corpse is piled up within it, have long-pending thermal effect, are unfavorable for very much the heat radiation of casing.In China south, the cockroach breeding is very fast, also is very rapidly so LED display is threatened.
The utility model content
The utility model technical matters to be solved is: a kind of LED display is provided, and it has a kind of structure that can prevent this type of cockroach reptile entering LED casing, avoids destruction and the adverse effect of reptile to casing.
In order to solve above-mentioned technical matters, the utility model proposes a kind of LED display of insect protected structure, comprises the casing of LED display, on casing, is provided with fan, and
Air outlet at fan is provided with right-angle bend, and one of right-angle bend terminates on the air port, and Open Side Down is provided with for another;
On one section downward inwall of bend pipe, be provided with the smooth interior cover of layer of surface;
On the casing, fan below be provided with air admission hole, the aperture of air admission hole is provided with the cover of band net.
Cover will have certain elasticity in it should be noted that, can conveniently fill in the bend pipe like this, and be close together with bend pipe.
Preferably: be provided with in said right-angle bend corner and collude groove, said in the upper end of cover be provided with overhead kick, overhead kick is hooked in colludes in the groove.
Preferably: one section the bottom downward at said bend pipe is provided with to the flanging that turns up, and colludes groove under flanging is formed with, and said interior cover bottom is connected with flanging, colludes in the groove under the flanging invagination is said.
Preferably: the aperture of said air admission hole is provided with swivel nut, and said cover is threaded with swivel nut.
Preferably: flanging is tinfoil or aluminium foil.
Preferably: the cover main body is a steel plate in said, and surface of steel plate is through polishing or electroplating processes.
The beneficial effect of the utility model:
Compare prior art, the utility model is provided with a bend pipe on the air port of fan, this bend pipe down, its inwall is provided with smooth interior cover.Such structure can prevent that this type of cockroach reptile from being climbed in the casing by the air port of fan, and interior cover is replaceable structure, use a period of time after, can remove and clean or change.The utility model technical scheme can prevent effectively that this type of cockroach reptile from getting into casing, prevents that them from biting gnawing of components and parts on the casing interior circuit board, and prevents the accumulation of reptile corpse in casing, improves the heat dissipation environment of LED.
