[0001] The utility model relates to the technical field of LED display modules, and particularly relates to an LED display module with a waterproof structure. Background Technique
[0002] In recent years, the technology of large-size display screens has developed rapidly, and more and more large-size display screens have appeared around us. Now, large-screen display screens are composed of several LED display modules. Therefore, the LED screen display module is the key to large-size display screens. At the same time, the rear side of each LED display module is often closed by a sealing door to protect the wires inside the LED display module. However, since each display screen is assembled with multiple LED display modules, in order to improve the installation efficiency of the LED display module, the sealing doors on its rear side are often naturally closed without items such as latches for positioning. As a result, in rainy days, when the wind force is too strong, the sealing doors are very easy to be blown open, allowing rainwater to enter the inside of the display module along with the wind and causing a short circuit in the circuit. Therefore, we propose an LED display module with a waterproof structure to solve the above problems. Content of the Utility Model

The waterproof mechanism 4 is snap-fitted with the water baffle 3.
[0025] As Figures 4 to 8 shown, in another embodiment of the utility model, the waterproof mechanism 4 includes a first sealing door 401 and a second sealing door 402. The first sealing door 401 and the second sealing door 402 are respectively installed at both ends of the rear side of the module frame 1 through hinges. A limiting plate 412 is installed at the upper end of the rear side inside the module frame 1. The limiting plate 412 is in contact with the first sealing door 401 and the second sealing door 402. Sealing gaskets are installed between the limiting plate 412 and the rear side of the module frame 1, and the sealing gaskets are in contact with the first sealing door 401 and the second sealing door 402. A sealing block 403 is installed on one side of the first sealing door 401 close to the second sealing door 402. The sealing block 403 is snap-fitted inside the second sealing door 402. A groove 404 is provided at the upper end of the rear side inside the module frame 1. A push rod 408 is movably penetrated through the groove 404. A clamping block 409 is movably installed at the upper end of the rear side of the module frame 1. The rear end of the push rod 408 is connected to the clamping block 409. The clamping block 409 is in contact with the first sealing door 401 and the second sealing door 402. A movable plate 405 is movably installed inside the groove 404. The front end of the movable plate 405 is connected to the push rod 408. Guide rods 406 are respectively installed at both ends inside the groove 404. Springs 407 are respectively sleeved on the outer sides of the guide rods 406 between the rear side of the movable plate 405 and the groove 404. A first slider 411 is installed at the upper end of the clamping block 409. A first chute 410 is provided on the lower surface of the water baffle 3 and close to the first slider 411.

[0026] The user installs each LED display screen 2 on the module rack 1 through screws, and conducts the sealing work through the gasket between the LED display screen 2 and the module rack 1. Then the user can assemble the module rack 1 to form a large display screen. When it is necessary to open the first sealing door 401 and the second sealing door 402 at the rear of the module rack 1, the user only needs to pull the clamping block 409 all the time, so that the clamping block 409 is separated from the first sealing door 401 and the second sealing door 402. At the same time, the clamping block 409 will also pull the push rod 408 and the movable plate 405, so that the movable plate 405 squeezes the spring 407. Then the user can open the first sealing door 401 and the second sealing door 402. After opening the first sealing door 401 and the second sealing door 402, the user can release the clamping block 409, so that the clamping block 409 is reset and will not prevent the user from arranging the wires inside the module rack 1. Then when it is necessary to close the first sealing door 401 and the second sealing door 402, the user only needs to pull the clamping block 409 again, and then can close the first sealing door 401 and the second sealing door 402. After the closing is completed, the clamping block 409 can be released, so that the spring 407 pushes the movable plate 405, the push rod 408 and the clamping block 409 to be reset, and the clamping block 409 stably clamps and positions the first sealing door 401 and the second sealing door 402;
[0027] The sealing block 403 is used for sealing the connection part of the first sealing door 401 and the second sealing door 402, further improving the overall sealing performance;
[0028] The guide rod 406 is used to assist the movable plate 405 to move, improving the stability performance during the moving process;
[0029] After the module rack 1 is assembled, the user pulls the clamping block 409 outwards. Then the user installs the water baffle 3 on the upper surface of the uppermost module rack 1 through the cooperation of the second slider 5 and the second chute 6. After the water baffle 3 moves to the specified position, the user can release the clamping block 409. When the clamping block 409 is reset, it will drive the first slider 411 to snap into the inside of the first chute 410, so that it can cooperate with the second slider 5 and the second chute 6 to stably position the water baffle 3, and the water baffle 3 stably blocks the rainwater.
[0030] The working principle of the LED display module with a waterproof structure:
[0031] In use, first, the user installs each LED display screen 2 on the module rack 1 through screws and seals it through the gasket between the LED display screen 2 and the module rack 1. Then, the user can assemble the module rack 1 to form a large display screen. When it is necessary to open the first sealing door 401 and the second sealing door 402 at the rear of the module rack 1, the user only needs to pull the clamping block 409 all the time to separate the clamping block 409 from the first sealing door 401 and the second sealing door 402. At the same time, the clamping block 409 will also pull the push rod 408 and the movable plate 405 to make the movable plate 405 squeeze the spring 407. Then, the user can open the first sealing door 401 and the second sealing door 402. After opening the first sealing door 401 and the second sealing door 402, the user can release the clamping block 409 to make the clamping block 409 reset so as not to interfere with the user's arrangement of the wires inside the module rack 1. When it is necessary to close the first sealing door 401 and the second sealing door 402, the user only needs to pull the clamping block 409 again, and then can close the first sealing door 401 and the second sealing door 402. After closing, the user can release the clamping block 409 to make the spring 407 push the movable plate 405, the push rod 408 and the clamping block 409 to reset, so that the clamping block 409 stably clamps and positions the first sealing door 401 and the second sealing door 402. After the module rack 1 is assembled, the user pulls the clamping block 409 outwards. Then, the user installs the water baffle 3 on the upper surface of the uppermost module rack 1 through the cooperation of the second slider 5 and the second chute 6. After the water baffle 3 moves to the designated position, when the user releases the clamping block 409 and the clamping block 409 resets, it will drive the first slider 411 to snap into the inside of the first chute 410, so that it can cooperate with the second slider 5 and the second chute 6 to stably position the water baffle 3 and make the water baffle 3 stably block the rainwater.
