Abstract

The invention discloses a light-emitting diode (LED) display screen body framework. Side walls of the LED display screen body framework have hollowed structures; two side walls of the framework comprise an outer layer, a middle layer and an inner layer which have the hollowed structures; the hollows of the outer layer and the middle layer are vertically formed on the side walls of the framework at intervals and in a staggered way; the hollow of the outer layer is formed at a corresponding hollowed position of the middle layer; cap brims are arranged on the outer sides of the hollowed outer layer, middle layer and inner layer; the cap brims of the hollows of the outer layer and the middle layer face downward; and the cap brim of the hollow of the inner layer faces upward. The LED display screen body framework has excellent ventilating, convecting and radiating effects and excellent water-proof performance and the protective level of the LED display screen body framework can reach ingress protection (IP)65.

Description

A kind of LED display body framework

Technical field

The present invention relates to a kind of LED display, more particularly, relate to a kind of LED display body frame structure that possesses good heat radiating and water-proof function.

Background technology

The height of LED display heat dispersion can directly influence the life-span of its use.Common LED display outside framework adopts single layer aluminium sheet or steel plate, offers hollow out on the frame wall outside, installs an air-conditioner in outside framework inside or fan solves heat dissipation problem.But under the outdoor application environment, not only require display screen that good heat radiation is arranged, and require to have higher degree of protection, such as moistureproof, waterproof.If the display screen outside framework adopts above-mentioned common frame mode, its degree of protection can not done very highly, even can't satisfy outdoor environment for use.Also have, when display screen being carried out daily cleaning, maintenance and safeguarding, need with a large amount of surperficial dusts of water flushing, said structure will certainly cause a large amount of water to enter display frame inside, and the normal use of framework internal unit and circuit is impacted.

Summary of the invention

At the defective that exists in the above-mentioned prior art, technical problem to be solved by this invention provides a kind of LED display body framework, under the situation that possesses good ventilating convection heat radiation, has very high degree of protection again.

For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:

A kind of LED display body framework, its sidewall has engraved structure, it is characterized in that, the two side of described framework by have engraved structure outer, in, interior three layers form, hollow out on described outer, the middle level on the vertical direction of frame side wall at interval and dislocation offer, the hollow out on the described internal layer is opened in the hollow out position in corresponding middle level, described hollow out outside, in, the outside of internal layer all has the brim of a hat, outward, the brim of a hat of the hollow out on the middle level down, the brim of a hat of the hollow out on the internal layer is up.

Described hollow out with one group be the unit gap be opened in frame side wall outer, in, on the internal layer.

Described one group is a plurality of forming to the strip hollow out of opening along level of being arranged side by side.

Described internal layer is made up of several unit, and the two ends up and down of described each unit are mounted on the place, two ends up and down of the inboard corresponding described per unit in middle level.

The lower end of each unit of corresponding internal layer offers osculum on the middle level.

The described hollow out the brim of a hat is the integral type arc shape that is stamped to form with frame side wall.

The described hollow out the brim of a hat outer, the middle level is the integral type arc shape that is stamped to form with frame side wall, and the hollow out the brim of a hat of described internal layer is for independently being installed in the shape of facing directly in the internal layer outside.

The hollow out position of the internal layer of described outside framework one sidewall is equipped with the air filtration guard.

The beneficial effect of technical solution of the present invention is as follows:

LED display body framework disclosed in this invention adopts three-decker, all offers hollow out on every layer, carries out the cross-ventilation heat radiation by the relative both sides of framework.All have the brim of a hat on the hollow out, and the brim of a hat on outer, the middle level up, this structure has prevented that rainwater from top to down from entering framework.But when water pipe washes, have part from down and on water enter skin because the hollow out on outer, the middle level shifts to install at interval, enter outer field water greatly can be blocked by the middle level, seldom part enters the middle level.Internal layer is arranged on the hollow out position in corresponding middle level, and the brim of a hat on the hollow out of internal layer up, and the water that enters the middle level on a small quantity can be blocked by internal layer.Extraneous water has been blocked in the design of three-decker so fully, has prevented that water from entering the damage that cause equipment and circuit outside framework inside.Further by osculum is set on the middle level, will enter the middle level and discharged by the water that internal layer blocks, do not have water year in and year out yet and accumulate and cause a large amount of phenomenon of getting rusty of metal framework.The disclosed LED display body of technical solution of the present invention framework, its degree of protection can reach IP65.
