[0002] With the technological advancement of LED display screens and the expansion of their application areas, there are more segmented LED display screens for different application fields, such as advertising screens, stage rental screens, door head screens, indoor small spacing, traffic guidance screens, etc. Outdoors, there is a kind of LED display screen that stands out from the crowd, which is the currently popular LED grille display screen, which is mainly used in urban advertising and picture display, and has a very wide range of uses.

[0003] The existing LEDs used for outdoor traffic guidance are set on one side of the highway. Because they are set in the external environment, it is common to encounter rainy weather. The existing outdoor LED display screens are connected and packaged with each other through the outer shell. When exposed to rain and sun for a long time, the gaps in the shell are easily damaged by oxidation, causing rainwater to easily penetrate into the shell through the gaps and cause circuit damage to the LED module, affecting the normal display use of the LED screen. For this reason, we propose a waterproof and explosion-proof LED screen. Utility Model Content

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a waterproof and explosion-proof LED screen.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a waterproof and explosion-proof LED screen, comprising a shell and an LED display assembly, an explosion-proof glass is installed at the front position of the interior of the shell, a packaging back plate is arranged on the back side of the shell, docking parts are installed on the upper and lower sides of the interior of the shell, a packaging pad is arranged on the inner surface of the shell, and the packaging pad itself has a deformation characteristic, a drainage groove running through the interior of the shell is opened on the top of the shell, a guide bevel forming a slope is opened on the top of the packaging back plate, and a guide plate is installed on the back side of the packaging back plate.

[0006] Preferably, the interior of the drainage groove is a rectangular inclined hollow groove body, and one side of the guide plate is an arc-shaped wall surface, so that the external liquid can be guided downward through the drainage groove when passing through the drainage groove.

[0007] Preferably, the liquid is in a secondary diversion state through the diversion oblique port. When the liquid flows into one side of the curved surface of the guide plate through the diversion oblique port, the liquid is in a diversion and discharge state through the guide plate.

[0008] Preferably, the cross-section of the packaging pad is a trapezoidal pad body and the inner side of the packaging pad is an inclined surface. When the packaging back plate is installed inside the shell, the outer periphery of the packaging back plate is packaged with the inner side of the shell through the packaging pad, and one side of the packaging back plate is docked with the docking piece.

[0009] Preferably, fixing screw grooves penetrating the packaging back plate are provided on both the upper and lower sides of the housing, and the internal threads of the fixing screw grooves are connected with fixing bolts for fixing the packaging back plate.

[0010] Preferably, a cooling plate docking with the LED display assembly is arranged on the back side of the LED display assembly, a storage cavity for storing cooling medium is provided inside the cooling plate, and a heat dissipation channel cooperating with the LED display assembly to dissipate heat is provided inside the cooling plate.

[0011] Preferably, a connector that docks with the inner side of the outer shell is installed at the bottom of the cooling plate. The connector is an L-shaped structure. A screw hole that passes through the outer shell is opened above the connector. The internal thread of the screw hole is connected to a bolt that fixes the cooling plate.

[0012] Beneficial Effects

[0013] The utility model provides a waterproof and explosion-proof LED screen. It has the following beneficial effects:

[0014] 1. A waterproof and explosion-proof LED screen. In this article, the packaging backplane is located on the back side of the inner shell and is embedded in the packaging. A packaging pad is arranged on the inner side of the shell. The inner side of the packaging pad is an inclined structure. When the packaging backplane is inserted into the inner shell and gradually approaches the docking part, the inner side of the packaging pad and the outer periphery of the packaging backplane are increasingly closely matched. After the fixing bolts are installed with the inner threads of the fixing screw grooves, the packaging backplane can be fixed inside the shell. When rainwater from the outside falls on the upper part of the shell, the rainwater on the left side of the shell can be blocked and protected by the explosion-proof glass. When the rainwater flows on the right side above the shell, the rainwater can first be guided downward through the drainage groove to fall on the surface of the guide bevel. The fallen rainwater is then guided onto the guide plate on the back side of the packaging backplane through the guide bevel. The rainwater can be smoothly diverted and discharged through the arc-shaped wall on one side of the guide plate to avoid docking penetration, thereby achieving the effect of improving the sealing of the inner part of the shell and the packaging backplane and avoiding short-circuit damage to the LED display component that affects normal use.

[0015] 2. A waterproof and explosion-proof LED screen, wherein a group of cooling plates are arranged on the back side of the LED display component, and the cooling liquid medium can be stored in the storage cavity inside the cooling plate, so that the low temperature of the cooling liquid medium can be transferred to the LED display component through the cooling plate to reduce the overall high temperature heat of the LED display component, and a plurality of heat dissipation channels penetrating the entire cooling plate are arranged inside the cooling plate, and the heat dissipation of the LED display component itself can be assisted through the heat dissipation channels, thereby improving the heat dissipation effect of the LED display component itself.
