[0030] Waterproof sealing structure of LED display, such as Figure 1-Figure 3As shown, it includes an LED display screen body 30 and a semi-enclosed sealed outer shell 10, a sealing gasket 20 is arranged between the LED display screen body 30 and the sealed outer shell 10; a mounting groove 11 for placing the LED display screen body 30 is opened on one side of the sealed outer shell 10, and fixing screw holes 13 are opened at four top corners of the mounting groove 11; a sealing ring 31 with an interference fit with the inner wall of the mounting groove 11 is installed on the edges of the LED display screen body 30, and a fixing ring seat 32 is installed on the edge of the LED display screen body 30, and the fixing ring seat 32 and the outer wall of the edge of the LED display screen body 30 are an integrally formed structure. By providing the semi-enclosed sealed outer shell 10 and the sealing gasket 20, and the sealing ring 31 with an interference fit with the inner wall of the mounting groove 11 installed on the edges of the LED display screen body 30, the LED display screen has excellent waterproof sealing performance, effectively preventing water and moisture from invading the interior of the display screen, protecting the normal operation of the display screen and extending the service life. At the same time, the fixed ring seat 32 at the edge of the LED display screen body 30 is an integrally formed structure with the outer wall of the edge of the display screen, which further enhances the structural strength and stability of the display screen. Combined with the fixing screw holes 13 at the four top corners of the mounting groove 11, the installation of the display screen is more firm and reliable, thereby improving the durability and use effect of the overall product.
[0031] Furthermore, a plurality of evenly and equidistantly arranged thermal fins 12 are embedded and installed on a surface of one side of the sealed outer shell 10 away from the LED display screen body 30. The thermal fins 12 pass through the outer wall of the sealed outer shell 10 and extend into the mounting groove 11. The thermal fins 12 and the sealed outer shell 10 are an integrally formed structure, so that the heat generated by the display screen during operation can be effectively dissipated through the thermal fins 12, thereby improving the heat dissipation performance of the display screen and extending the service life of the display screen.
[0032] It is worth noting that there is a distance of at least 3 mm between the thermal fins 12 and the back of the LED display body 30, which not only ensures that the thermal fins 12 can effectively dissipate heat, but also avoids the risk of short circuit or damage caused by direct contact between the thermal fins 12 and the LED display body 30.
[0033] Among them, the four top corners of the sealing gasket 20 and the fixing ring seat 32 are provided with through holes 21 and fixing holes 33 that are adapted to the size and corresponding to the position of the fixing screw holes 13, so that during installation, the sealing gasket 20, the fixing ring seat 32 and the sealed outer shell 10 can be tightly fixed into an integrated structure through the fixing bolts 40, thereby improving the installation stability and sealing performance of the display screen.
[0034] Specifically, a limiting ring seat 34 is provided on the inner wall of the sealed outer shell 10 to limit the position of the LED display screen body 30 in the installation groove 11 to prevent it from shifting during installation or use, thereby further improving the installation stability and use effect of the display screen.
[0035] In addition, the sealing ring 31 is made of soft silicone or latex material with an arc-shaped cross-section, and the height of the protrusion is 1-2 mm, so that the sealing ring 31 can better fit with the inner wall of the installation groove 11 to form an effective waterproof sealing layer. At the same time, it has a certain elasticity, which can buffer the pressure of the display screen when it is impacted by external force and protect the display screen from damage.
[0036] It is worth noting that the sealing gasket 20 is made of a rubber material with a thickness of 3-5 mm, which not only ensures that the sealing gasket 20 has sufficient elasticity and sealing performance, but also can effectively isolate water and moisture to protect the internal structure of the display screen from damage.
[0037] The working principle of the waterproof sealing structure of this LED display:
[0038] (1) Preparation stage:
[0039] Ensure that the LED display screen body 30, the semi-enclosed sealed outer shell 10, the sealing gasket 20 and the required fixing screws and other accessories are complete.
[0040] (2) Install the sealing gasket:
[0041] The sealing gasket 20 is placed on the contact surface between the LED display screen body 30 and the sealed outer shell 10, ensuring that the gasket covers the entire contact area to provide a good sealing effect.
[0042] (3) Place the LED display screen:
[0043] Place the LED display screen body 30 into the mounting groove 11 of the sealed outer shell 10 , and make sure that the sealing ring 31 around the edge of the display screen body 30 forms an interference fit with the inner wall of the mounting groove 11 to ensure sealing.
[0044] (4) Fix the display screen:
[0045] The LED display screen body 30 is firmly fixed to the sealed outer shell 10 using fixing screws through the fixing screw holes 13 at the four top corners of the mounting groove 11. When fixing, make sure that the screws are tightened to ensure the stability and durability of the display screen.
[0046] (5) Check the sealing:
[0047] After installation, carefully check the sealing condition of the sealing gasket 20 and the sealing ring 31 to ensure that there are no gaps or looseness to prevent water and moisture from invading the interior of the display screen.
[0048] (6) Testing and operation:
[0049] After ensuring good sealing, turn on the power and perform a functional test on the LED display to check whether the display is operating normally, whether the image is clear, and whether the colors are bright.
