For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0034] like Figures 1 to 8As shown, this utility model provides a waterproof LED enclosure structure, including an enclosure frame 1 and a power supply box 2. The enclosure frame 1 includes a side frame and a power supply bottom shell connected to the side frame. The power supply bottom shell and the power supply box 2 fit together. When the power supply bottom shell and the power supply box 2 are assembled as one unit, a hollow structure is formed between the power supply bottom shell and the power supply box 2, which can hold electronic components. The side frame is a square frame, and a cross is fixedly connected inside the side frame. The four ends of the cross are fixedly connected to the four sides of the side frame. The cross divides the enclosure frame 1 into four small frames. The intersecting parts of the cross are fixedly connected to the power supply bottom shell. The enclosure frame 1, the cross, and the power supply bottom shell are integrally set.
[0035] The power supply base has a square structure. The upper surface of the base has mounting grooves 5 and a first water guide groove 6 around its perimeter. The mounting grooves 5 and the first water guide groove 6 are adjacent and parallel to each other, with their bottoms on the same plane. Several locking fittings are fixedly connected to the left and right ends of the power supply base. In this embodiment, two locking fittings are fixedly connected to each of the two side faces of the power supply base, and the locking fittings on the two side faces are symmetrically arranged. The locking fittings are lock seats.
[0036] The power supply box 2 has an open box-like structure. A pressing boss 12 and a water-blocking boss 13 are fixedly connected to the upper surface of the side wall of the power supply box 2. The pressing boss 12 and the water-blocking boss 13 are adjacent and parallel to each other, with the upper surface of the pressing boss 12 lower than the upper surface of the water-blocking boss 13. The pressing boss 12 fits into the mounting groove 5, and the water-blocking boss 13 fits into the first water guide groove 6. A sealing device 3 is installed between the pressing boss 12 and the mounting groove 5. One end of the sealing device 3 is tightly attached to the mounting groove 5, and the other end of the sealing device 3 has a first groove 14. The first groove 14 is tightly attached to the surface of the pressing boss 12, making the enclosure frame 1 and the power supply box 2 fit tightly together. The sealing device 3 is a sealing ring made of silicone. The sealing ring fits tightly between the power supply box 2 and the enclosure frame 1. Under high temperature conditions, it will not soften, deform, or lose elasticity, effectively preventing liquid from entering the power supply box 2.
[0037] Since the bottom of the mounting groove 5 and the first water guide groove 6 are in the same plane, and the upper surface of the pressing boss 12 is lower than the upper surface of the water-blocking boss 13, when the pressing boss 12 is placed in the first groove 14 of the sealing device 3 and the water-blocking device is placed in the first water guide groove 6, the liquid that seeps through the sealing device 3 is blocked by the water-blocking boss 13 to the side of the mounting groove 5, and then discharged from the box frame 1, ensuring the safe operation of the electronic components inside the power supply box 2.
[0038] Several locking components 8 and drainage components 10 are fixedly connected to the left and right end faces of the power supply box 2. In this embodiment, two locking components 8 and two drainage components 10 are fixedly connected to the two side end faces of the power supply box 2 respectively. The locking components 8 and drainage components 10 on the two side end faces of the power supply box 2 are symmetrically arranged. The locking components 8 cooperate with the locking mating components. In this embodiment, the locking component 8 is a buckle. The buckle cooperates with the locking seat to lock the power supply box 2 onto the box frame 1. A through hole 15 is passed through the drainage component 10. The through hole 15 is interconnected with the inside of the power supply box 2. The through hole 15 is used for signal communication between the inside and outside of the power supply box 2 and for setting up the power supply connector. The through hole 15 is located on the lower end face of the drainage component 10, and the opening direction of the through hole 15 is downward, so that the liquid on the drainage component 10 does not easily flow directly into the power supply box 2 through the through hole 15. The drainage component 10 corresponds to the signal connector placed inside the power supply box 2, and the drainage component 10 corresponds to the power supply placed inside the power supply box 2. The drainage component 10 includes a drainage surface 16, which is inclined to the outer surface of the power supply box 2. A second water guide groove 11 is provided on the outer edge of the drainage surface 16. Specifically, the drainage surface 16 is an inclined surface, which is the upper surface of the drainage component 10. The drainage surface 16 has an inclination angle relative to the vertical direction and an inclination angle relative to the front and back direction of the drainage component 10. This allows the liquid to flow along the drainage component 10 when the power supply box 2 is exposed to rain, accidental splashes, or condensation, thus promptly draining the liquid from the power supply casing and preventing it from entering the power supply box 2 and damaging the electronic components. It also reduces the possibility of liquid flowing into the device along the connection points, further extending the service life of the LED display screen using the LED cabinet of this utility model.
[0039] The power supply box 2 is also provided with several first fixing devices, and the power supply bottom shell is provided with several second fixing devices. The first fixing devices and the second fixing devices cooperate with each other to fix the power supply box 2 to the power supply bottom shell. In this embodiment, the power supply box 2 is provided with several first locking holes 9, and the power supply bottom shell is provided with several second locking holes. The first locking holes 9 and the second locking holes correspond one-to-one. Specifically, one first locking hole 9 is provided on each of the four sides of the power supply box 2, and one second locking hole is provided on each of the four edges of the power supply bottom shell. Screws are passed through the first locking holes 9 and the second locking holes in sequence to fix the power supply box 2 and the power supply bottom shell together.
[0040] The bottom of the power box 2 is also equipped with a breather valve 4. When the internal pressure of the power box 2 increases, the breather valve 4 can automatically open to release the gas inside the power box 2. When the internal pressure of the power box 2 decreases, the breather valve 4 can automatically open to allow external gas to enter the power box 2, thereby preventing the power box 2 from sucking back liquid and achieving the effect of balancing the internal and external air pressure of the power box 2.
[0041] The surface of the power supply box 2 is provided with heat dissipation fins 7 to facilitate heat dissipation of the components inside the power supply box 2.
[0042] The surface of the power box 2 is coated with a hydrophobic material, which can quickly drain away liquids on the surface of the power box 2 and prevent water vapor from condensing into frost or ice.
[0043] This utility model's LED enclosure integrates the power supply box 2 by placing a pressing boss 12 within the first groove 14 of the sealing device 3, placing a water-blocking device within the first water-guiding groove 6, and mounting the sealing device 3 between the pressing boss 12 and the mounting groove 5. The enclosure frame 1 and the power supply box 2 are tightly assembled as one unit. The locking component 8 and the locking mating component work together, and the first fixing device and the second fixing device work together. This double-fixing configuration locks the power supply box 2 onto the enclosure frame 1, significantly improving the sealing performance of the assembly between the power supply box 2 and the enclosure frame 1. The sealing device 3, along with the mounting groove 5, the first water-guiding groove 6, the pressing boss 12, and the water-blocking boss 13, effectively prevents liquid seeping through the sealing device 3 from flowing into the power supply box 2. The drainage component 10 effectively drains liquid from the power supply casing, greatly improving the waterproof performance of the LED enclosure.
