Description

Waterproof and dampproof outdoor LED color screen

Technical field

This utility model relates to LED field technology, refers in particular to a kind of waterproof and dampproof outdoor LED color screen.

Background technology

LED display is increasingly widely applied in productive life, along with the development of LED application technology, adds new vitality to advertising with keen competition.Owing to LED display has exclusive, different light emitting species, it is widely used and shows field in the making field of advertised product and variety scene stage.

Along with the appearance of outdoor media, the application of outdoor LED display screen is more widespread.Generally, the area of outdoor LED display screen general tens square metres to hundreds of square metre even more big, brightness is high, visual angle can work in the sun greatly, and have certain Radix Saposhnikoviae, rainproof, water-proof function, is mainly used in outdoor advertising, station, square, market etc..

LED display is generally spliced to form by multiple LED display modules; LED display module generally comprises plastics drain pan, wiring board and the LED being arranged on wiring board; only by peripheral box sealing to play waterproof effect; and use face shield to protect LED; but, mask designs cost is high and processing technique is complicated and is difficult to control to.But, when flatness, water resistance and effective heat radiation etc. of LED display module go wrong, LED display display effect will be affected and quality problem occurs, such as visual angle diminishes, have aberration, have shade, have color lump etc., thus cannot meet the quality criteria requirements that LED display shows.

Utility model content

In view of this, this utility model is for the disappearance of prior art existence, and its main purpose is to provide a kind of waterproof and dampproof outdoor LED color screen, solves LED display module water proofing property problem in prior art.

For achieving the above object, this utility model uses such as purgation technical scheme:

A kind of waterproof and dampproof outdoor LED color screen, including shell, front panel, light barrier, LED module, circuit board；The front end face of this shell is provided with an open ports, and the week of this open ports, along being arranged with rhone, installs sealing ring in this rhone；Described front panel covers at this shell to close this open ports.

As a kind of preferred version, described rhone by surrounding the first concave surface of "U" shaped, the second concave surface, the 3rd concave surface form, the 3rd concave surface is provided with screw, and screw is through the sealing ring in screw locking rhone.

As a kind of preferred version, the width of described sealing ring is close to the 3rd concave surface less than the width of rhone, this sealing ring, is conducive to the gap of draining between sealing ring and the first concave surface.

As a kind of preferred version, bonding marine glue between described front panel and the open ports of this shell.

As a kind of preferred version, described light barrier, LED module and circuit board are successively set in this open ports.

This utility model compared with prior art has clear advantage and beneficial effect, specifically, as shown from the above technical solution, it is mainly provided with rhone on shell, rainwater flows to rhone before the open ports entering case nose face and flows out, lock sealing ring by screw again, it is ensured that the steadiness that sealing ring is installed, improve sealing property.

For more clearly illustrating architectural feature of the present utility model and effect, with specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.

Detailed description of the invention

Refer to shown in Fig. 1 to Fig. 4, that show the concrete structure of the preferred embodiment of this utility model, be a kind of waterproof and dampproof outdoor LED color screen, including shell 10, front panel 20, light barrier 30, LED module 40, circuit board 50.

Wherein, this shell 10 is to use corrosion-resistant, antirust metal material, and this shell 10 is one-body molded, is provided with an open ports 11 in front end face, and the week of this open ports 11 is along being arranged with rhone 12.Described rhone 12 is made up of first concave surface the 121, second concave surface the 122, the 3rd concave surface 123 surrounding "U" shaped.This rhone 12 is installed sealing ring 13；For more stable fixed seal ring 13, the 3rd concave surface 123 is provided with screw 124, and screw 14 locks the sealing ring 13 in rhone 12 through screw 124.As shown in Figure 4, the width of described sealing ring 13 is close to the 3rd concave surface 123 less than the width of rhone 12, this sealing ring 13, is conducive to the gap 15 of draining between sealing ring 13 and the first concave surface 121.

Described front panel 20 covers at this shell 10 to close this open ports 11, bonding marine glue 16 between this front panel 20 and open ports 11 of this shell 10, improving water resistance further, described light barrier 30, LED module 40 and circuit board 50 are successively set in this open ports 11.Being sealed by said structure, it is ensured that dampness, rainwater can not penetrate into the inner space of shell 10, light barrier 30, LED module 40 and circuit board 50 are arranged on the inside, it is not necessary to worry immersion problem.

Operation principle of the present utility model is: when rainwater sprinkle is at the shell 10 of this LED color screen, owing to shell 10 is one-body molded, rainwater can not from top, sidepiece and rear penetrate into internal；It addition, uniquely have the week of open ports 11 along being provided with rhone 12, can be drained by rainwater, further increase sealing ring 13 and marine glue 16 carries out dual antiseepage, inner space fully seals, it is ensured that water resistance.

In sum, design focal point of the present utility model is, it is mainly provided with rhone 12 on shell 10, rainwater flows to rhone 12 before the open ports 11 entering shell 10 front end face and flows out, sealing ring 13 is locked again by screw 14, guarantee the steadiness that sealing ring 13 is installed, improve sealing property.

The above, it it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore every any trickle amendment, equivalent variations and modification above example made according to technical spirit of the present utility model, all still fall within the range of technical solutions of the utility model.
