Description
Technical field
The present invention relates to LED display, particularly a kind of LED hollow out screen that is provided with gas-tight silo and respirator.
Background technology
LED display is used for multimedia information dissemination, and belong to the terminal and show carrier, be the important symbol of intelligent city, all be widely used in socioeconomic various fields.Be mainly reflected in multiple needs such as government at all levels, public organization, group company, market, stadiums, showground, meeting venue, building construction, financial instrument place, airport, station, harbour, urban road, intelligent transportation information, advertising, adnornment industry, mass information, hospital, stage background and carry out the field of picture and text, chart and multimedia display.Along with socioeconomic continuous progress, and the LED display technique is constantly perfect, and people are more and more deep to the understanding of LED display, and its application is also being expanded day by day.
Current widely used LED display has several kinds of forms such as indoor, open air and semi-outdoor.Its structure comprises module, casing, power supply, drive plate, radiator fan and the control circuit board of being made up of the LED display circuit board etc., and the polylith module is located at the surface of casing, and power supply, radiator fan and control circuit board are set in the casing.Be arranged to form the LED display of giant-screen by a plurality of casings.Casing is arranged on the fixed mount during installation, is connected with angle Support through securing members such as bolt, screws between the casing.Many, the inconvenient machining of manufacturing procedure when the display screen of this structure is produced; Casing is thick, heavy, inconvenient installation; And the gap between the casing is big, inhomogeneous; " piece " that causes the big screen display screen images displayed to be cut apart by the gap is fairly obvious; And the out-of-flatness of monoblock plane causes display image to be distorted easily, and the giant-screen local project or dent causes the angle of visibility of display screen the situation at dead angle to occur.
For addressing this problem the LED hollow out screen that designs; Its structure comprises the demonstration module of being made up of face shield, PCB (Printed Circuit Board, printed circuit board (PCB)), drain pan and frame, and face shield, PCB and drain pan order are spliced; Drain pan is connected with frame; Frame is provided with corner connector, and power supply and control circuit board are arranged on the back side of drain pan, and each shows that module is linked as monoblock LED hollow out display screen through corner connector and active connection.Though this LED hollow out screen is light, thin, " piece " is not obvious, water resistance is relatively poor, when being used for outdoor and semi-outdoor; Power supply and control circuit board are prone to water inlet to be damaged; Therefore can only be used for indoorly, limit usable range widely, and because non-moistureproof; Also easily because the erosion of moisture causes power supply and control circuit board to break down, maintenance cost is higher in indoor use.
Summary of the invention
The objective of the invention is deficiency, and the LED hollow out screen of the light-duty waterproof that a kind of usable range is wide, maintenance cost is low is provided to prior art.
The objective of the invention is to realize through following technical scheme:
A kind of LED hollow out screen that is provided with gas-tight silo and respirator; Comprise the demonstration module of forming by face shield, PCB, drain pan, frame, power supply and control circuit board; The positive order of face shield, PCB and drain pan is spliced; Drain pan is connected with frame, and different with prior art is: also comprise the gas-tight silo that is arranged on the drain pan back side, power supply and control circuit board are arranged in the gas-tight silo.
Also comprise the water-proof ventilated respiration device that is arranged on the gas-tight silo bulkhead.
Described gas-tight silo is connected to form by middle plate and drain pan, and described water-proof ventilated respiration device is arranged on the middle plate.
The junction of said drain pan and middle plate is provided with the edge of keeping off the rain of twice protrusion, and the second inboard road keeps off the rain along being connected as a single entity with middle plate in the groove on edges of boards edge in the embedding, and the inboard of groove is the inclined-plane, also is provided with osculum on the groove.
The present invention adopts gas-tight silo and the design of respirator structure combining; Reach the effect that waterproof combines with draining; First, second road keep off the rain along rainwater retaining outside gas-tight silo, the inclined-plane of middle plate groove and freeing port, the water droplet of no hydraulic pressure that can prevent seepage is outside lower stream and discharge gas-tight silo; Respirator is under the weather extremes, and the gas-tight silo internal cause is expanded with heat and contract with cold and the water vapor that produces is discharged outside the storehouse, and the hydrone the storehouse outside can not be through in the respirator entering gas-tight silo.
LED hollow out of the present invention screen waterproof effect is better, can avoid the erosion to power supply and control circuit board of moisture and rainwater, both has been applicable to indoorly, also is applicable to open air, semi-outdoor use, has the advantage that usable range is wide, maintenance cost is low.

Embodiment
Below in conjunction with accompanying drawing and embodiment content of the present invention is done further to set forth, but be not qualification of the present invention.
Embodiment:
As shown in Figure 1; A kind of LED hollow out screen that is provided with gas-tight silo and respirator; Comprise the demonstration module of being made up of face shield 1, PCB2, drain pan 3, frame 4, power supply and control circuit board, the positive order of face shield 1, PCB2 and drain pan 3 is spliced, and drain pan 3 is connected with frame 4; Also comprise the gas-tight silo 9 that is arranged on drain pan 3 back sides, power supply and control circuit board are arranged in the gas-tight silo 9.
Also comprise the water-proof ventilated respiration device 8 that is arranged on gas-tight silo 9 bulkheads.
Particularly, gas-tight silo 9 is connected to form with drain pan 3 by middle plate 7, and water-proof ventilated respiration device 8 is arranged on the middle plate 7.
Drain pan 3 is provided with the edge of keeping off the rain that twice are protruded with the junction of middle plate 7; Promptly first road keeps off the rain and keeps off the rain along 6 along 5 and second road; The second inboard road keeps off the rain along being connected as a single entity with middle plate 7 in the groove 10 at plate 7 edges in 6 embeddings, and the inboard of groove 10 is the inclined-plane, also is provided with osculum 11 on the groove 10.
The design adopts gas-tight silo 9 and respirator 8 structure combining; Reach the effect that waterproof combines with draining; First road keeps off the rain to keep off the rain along 5 and second road and keeps off rainwater outside gas-tight silo 9 along 6; In inclined-plane and the freeing port 11 of plate groove 10, can prevent seepage no hydraulic pressure water droplet toward lower flow and discharge gas-tight silo 9 outside; In the gas-tight silo 9 because expand with heat and contract with cold, environmental temperature fluctuation such as temperature variation, erosion by wind and rain, solar radiation, all can cause pressure reduction and produce water vapor, under extremely low air pressure, can pass through outside the respirator 8 discharge storehouses.Water-proof ventilated respiration device 8 helps balanced seal storehouse 9 inside and outside pressure, prevents that air and moisture from getting in the storehouse, and can effectively protect the integrality of fluid sealant.Respirator 8 can waterproof, and aqueous vapor is discharged, and simultaneously gas freely is come in and gone out, thereby makes the purpose that reaches not only prevent dust hydrofuge but also equalized pressure in the gas-tight silo 9, makes gas-tight silo 9 maintenance waterproof, ventilative function.
