Abstract
The invention discloses a water-proof external member for an outdoor electronic display screen. The external member comprises a front panel and a plastic frame, wherein a circuit board is arranged in the plastic frame. The external member is characterized in that: the plastic frame is provided with drainage plates; the drainage plates are provided with drainage grooves and are arranged around the periphery of the plastic frame; a transverse drainage groove tilts towards two sides, namely water in the transverse drainage groove flows towards two sides from the center of the groove; and the upper transverse drainage pipe is wider than the lower transverse drainage pipe. The drainage plates of the external member can be used for directly receiving rainwater into the drainage grooves, and the rainwater flows into the lower drainage plate along the longitudinal drainage grooves on the two sides so as to enter the drainage groove of a next drainage plate; thus, the circuit board can be prevented from being soaked by the rainwater, and normal use of an outdoor large screen can be guaranteed. The external member has the advantages of light weight, low cost and high convenience for disassembly and assembly, and can be directly mounted in a magnetic attraction mode and overhauled from the front face.
Description
Technical field:
The present invention is specifically related to a kind of outdoor electronic display waterproof external member.
Background technology:
Outdoor electronic display waterproof external member is generally the plastic frame structure.In application process, exist by after the rain drop erosion, the wiring board that the screen behind often takes place is subjected to rainwater and drenches, and causes circuit to damage, and causes its outdoor large screen fault.The waterproof type that adopts is 1 at present: waterproof apron of folder on the outdoor module is fixed on the iron casing, play waterproof effect, but cost height, the thickness of displays of working it out is big, outward appearance is plain, main is that the later stage maintenance is inconvenient, needs the technician can remove electronics module just now behind the screen body; 2: beat glass cement out of doors between the module, play waterproof effect, but the later stage maintenance time need be severed glass cement again, or whole outdoor electronic display is removed.These two kinds of modes all are very inconvenient, and staff's labour intensity is higher.
Summary of the invention:
It is lower that the present invention aims to provide cost, overhauls outdoor easily electronic display waterproof external member.
The present invention includes front panel and plastic frame, wiring board is installed in the plastic frame, it is characterized in that plastic frame is provided with drainage plate.
Drainage plate is provided with drainage trough.
Drainage plate was provided with along one week of periphery of plastic frame, and laterally drainage trough tilts to both sides, and promptly laterally the trickling direction of drainage trough inner water is trickled to the groove both sides with groove center, and the groove width of the horizontal drainage trough of top is wide than the groove width of the horizontal drainage trough of below.
The xsect of drainage plate is L-shaped.
The xsect of drainage plate takes the shape of the letter U.
Drainage plate of the present invention can insert rainwater in the drainage trough, flow into the drainage plate of below along vertical drainage trough on both sides, enter the drainage trough of next piece drainage plate, like this, just can avoid wiring board to be soaked with rain, thereby can improve the waterproof effect of outdoor large screen, guarantee the steady display of outdoor display screen.
Advantage of the present invention is in light weight, and cost is low, can directly adopt magnetic-type installation, can overhaul from the front, and dismounting is very convenient.
Description of drawings:
Fig. 1 is the front view of the embodiment of the invention one.
Fig. 2 be Fig. 1 along A-A to sectional view.
Fig. 3 is the structural drawing (front view is identical with Fig. 1) of the embodiment of the invention two.
Among the figure, 1, plastic frame, 2, drainage plate, 3, bolt (being used for fixing plastic frame), 4, wiring board, 5, drainage plate, 6, drainage trough, 7, drainage trough, 8, drainage plate with magnetic.
Embodiment:
The specific embodiment of the present invention is not limited to following embodiment, can adopt different embodiment as the case may be.
Embodiment one: Fig. 1, shown in Figure 2, present embodiment comprises plastic frame 1, be provided with wiring board 4 in the plastic frame 1, it is characterized in that plastic frame 1 is provided with drainage plate, drainage plate is provided with drainage trough, the width of drainage trough 6 is than the wider width of drainage trough 7, be that drainage trough 6 can insert the current in the drainage trough 7, the xsect of drainage plate is L-shaped, drainage plate was provided with along one week of periphery of plastic frame, laterally drainage trough 6 is tilted to both sides by the centre, the trickling direction that is horizontal drainage trough inner water is trickled to the groove both sides with groove center, the groove width of the horizontal drainage trough 6 of top is than the groove width broad of the horizontal drainage trough 7 of below, and the current in the drainage trough 7 can flow in the drainage trough 6.
Embodiment two: shown in Figure 3, the xsect of the drainage plate 8 of present embodiment takes the shape of the letter U, and other structure is identical with embodiment one
