Abstract
The utility model provides an LED display screen box with a ventilation structure, which is provided with a structure capable of preventing reptiles such as cockroaches and the like from entering the LED box and avoiding damage and adverse effects of the reptiles to the box. The LED display screen box comprises an LED display screen box body with a fan, a right-angled bend is arranged at an air outlet of the fan, and one end of the right-angled bend is connected to the air outlet while the other opening of the right-angled bend is downward. An inner bush with smooth surface is arranged on a downward inner wall of the bend, an air inlet is arranged on the box body and below the fan, a mesh cover is arranged at the opening of the air inlet, and a ventilation hole is arranged on the bend and above the inner bush. The LED display screen box with the ventilation structure is capable of preventing reptiles such as cockroaches and the like from entering the LED box, preventing the reptiles from gnawing components on circuit boards in the box, and preventing accumulation of reptile remains in the box to improve the LED radiation environment.
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 casing with air-exchanging structure, comprises the fan that is located on the casing, 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;
On the bend pipe, interior cover above be provided with air-vent.
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 the hook groove in said right-angle bend corner, the upper end of said interior cover is provided with barb, and barb colludes in the hook groove.
Preferably: one section the bottom downward at said bend pipe is provided with to the flanging that turns up, and flanging is formed with hook groove down, and said interior cover bottom is connected with flanging, and flanging folds in the said hook groove down.
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.
Preferably: down one section of said bend pipe is uncovered, said in cover also be uncovered.The uncovered effect of strengthening this anti-creep has increased the difficulty that reptile creeps.
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.Owing on bend pipe, be provided with hook groove structure, therefore, the gas that is blown out by fan can produce backflow at hook groove place; This backflow is a hot-air, if can not in time shed, will influence radiating effect; Therefore; Above interior cover, air-vent is set, it can make the gas that circles round at hook groove place in time derive, and has strengthened radiating effect.It should be noted that air-vent can not be too big, Kong Taida, reptile can get in the bend pipe along the hole.
