To installing outdoor display screen device, because it installs in outdoor environment, when running into sleet weather, rainwater or snow water enter into the inside and influence the performance of display screen very easily, can lead to dangerous condition such as display screen short circuit even.

However, due to the frequent need of opening the screen for maintenance, the opening needs to be opened, and the screen display assembly 200 needs to be repaired or replaced, and after the opening is opened and closed for many times, the sealing strip loses the sealing effect easily, so that rainwater or snow water can easily infiltrate from the gap in rainy and snowy weather, and then the rainwater or the snow water enters the shell 100 and contacts the screen display assembly 200, thereby affecting the performance of the display screen, even damaging the electrical components on the screen display assembly 200, and causing short circuit and failure of the display screen.

In order to solve the problem, the utility model provides a display screen with waterproof function, except shell 100, still show subassembly 200 to the screen and carry out secondary waterproof sealing, even water infiltration shell 100 back, also can't show subassembly 200 contact with the screen easily, improved the security and the life of display screen.

In this embodiment, the above-mentioned secondary waterproof sealing structure is a sealing bracket 300, the sealing bracket 300 is disposed in the casing 100 and wraps the outside of the screen display assembly 200, and the screen display assembly 200 is connected to the sealing bracket 300 through a connecting structure. The sealing bracket 300 includes a first sealing frame 310 and a second sealing frame 320, the first sealing frame 310 and the second sealing frame 320 having an inner frame with a size matching the display assembly 200, and a transparent protection plate (not shown) adhered inside the inner frame.

The display panel assembly 200 is disposed between the first sealing frame 310 and the second sealing frame 320, and specifically, referring to fig. 4, the first sealing frame 310 is disposed below the display panel assembly 200, the second sealing frame 320 is disposed above the display panel assembly 200, and the transparent protection plate is opposite to the display panel assembly 200 for emitting light emitted from the display panel assembly 200.

The first sealing frame 310 and the second sealing frame 320 respectively clamp the screen display assembly 200 from the upper side and the lower side, and the upper side and the lower side of the screen display assembly 200 are sealed through the transparent protection plates; the first sealing frame 310 and the second sealing frame 320 are in matched connection through the first concave-convex structure 330, and are in tight connection through concave-convex matching, so that gaps are eliminated, the screen display assembly 200 is clamped and fixed, and the periphery of the screen display assembly 200 is sealed; through the setting of sealed support 300, can all wrap up, seal up screen display subassembly 200 everywhere, the sealed of cooperation shell 100 realizes dual waterproof, and shell 100 can block that the rainwater is got into by a large scale, and sealed support 300 then can avoid the rainwater or the steam infiltration screen display subassembly 200 of small part, avoids causing trouble or incident.

The casing 100 and the sealing bracket 300 can block most of water, but in case of extreme humidity, it is not excluded that water drops still enter the sealing bracket 300, therefore, referring to fig. 3, in this embodiment, the first concave-convex structure 330 is provided with a diversion trench 331, the diversion trench 331 is communicated with the casing 100 through a drainage structure, and the diversion trench 331 is used for collecting and discharging water entering the sealing bracket 300.

When the water drops penetrate into the contact position of the first sealing frame 310 and the second sealing frame 320 (i.e., the first concave-convex structure 330), the water drops flow into the flow guide groove 331 without continuously penetrating into the display screen assembly 200; the water drops are collected in the diversion trench 331 to form a small water flow, which can flow to a drainage position along the diversion trench 331, and only the water in the diversion trench 331 needs to be drained periodically.

Referring to fig. 2 to 4, in some embodiments of the present invention, the first concave-convex structure 330 extends around the display panel assembly 200, the first concave-convex structure 330 includes a first groove 332 and a first convex part 333 matching with the first groove, the first groove 332 is disposed on the first sealing frame 310, the first convex part 333 is disposed on the second sealing frame 320, and the first convex part 333 is embedded in the first groove 332 to achieve a sealing connection between the first sealing frame 310 and the second sealing frame 320.

Referring to fig. 3 to 4, in a further embodiment of the present invention, the diversion trench 331 is opened at one side of the bottom of the first groove 332 and is communicated with the first groove 332 to receive water entering into the first groove 332. When water penetrates the sealing holder 300, beads generally adhere to the contact surface of the first protrusion 333 and the first groove 332 and slide along the surface thereof, and when a plurality of beads slide to the bottom of the first groove 332, the beads are collected in the guide groove 331.

Referring to fig. 3 to 4, in a further embodiment of the present invention, in order to prevent water from flowing back from the diversion trench 331, the water absorption strip 334 is attached to the bottom of the first groove 332 and the opening of the diversion trench 331, the water absorption strip 334 can be made of sponge material, and no matter what state the display screen is in, the water in the diversion trench 331 cannot flow out from the first groove 332. The water absorbing strips 334 can prevent water from flowing backwards, absorb a small amount of water in the flow guide grooves 331 in time, keep the inside of the sealing support 300 dry, and are more beneficial to protecting the screen display component 200.

Further, the first protrusion 333 is slightly shorter than the first groove 332, and when the first protrusion 333 is inserted into the first groove 332, the bottom of the first protrusion 333 abuts against the absorbent strip 334 to press the absorbent strip 334, and the absorbent strip 334 maintains a certain expansion deformation space for the absorbent strip 334 to absorb water in time.

Referring to fig. 1 to 2, in a further embodiment of the present invention, the drainage structure includes a first diversion hole 311 and a second diversion hole 111, the first diversion hole 311 is opened on the first sealing frame 310 and is communicated with the diversion trench 331 (the first groove 332), the second diversion hole 111 is opened on the housing 100 and corresponds to the first diversion hole 311, when the display screen is put into use, the plug is inserted into the first diversion hole 311 and the second diversion hole 111, after a period of use, the plug is taken down, and water in the diversion trench 331 is drained.

Specifically, in order to more conveniently and rapidly discharge the water in the diversion trench 331, a plurality of first diversion holes may be provided, in this embodiment, one first diversion hole 311 is provided on each of four sides of the first sealing frame 310, and the housing 100 is also provided with a corresponding second diversion hole 111. After the display screen is removed from the installation position, the display screen may be rotated to discharge the water in the guide grooves 331 from the respective second guide holes 111.
