At the same time, the outer edge 202 can be installed inside the front frame 102, which facilitates the docking of the support frame assembly 2 with the LED module and the housing assembly 1, as well as the water-proof sealing of the unit as a whole. The setting of the heat-conducting plate 203 facilitates front-guided heat dissipation.

[0024] like Figures 4-5As shown, a sealing assembly 3 is provided between the main support frame 201 and the main housing 101. The sealing assembly 3 includes a filling groove 301, a waterproof sealing strip 302, and a filling tube 303. The filling groove 301 is provided in the middle of the outer side of the main support frame 201, and waterproof sealing strips 302 are provided on both the front and rear sides of the filling groove 301. The waterproof sealing strips 302 are embedded in the main support frame 201. A filling tube 303 is fixed in the lower middle part of the main housing 101, and the filling tube 303 is interconnected with the filling groove 301. The waterproof sealing strip 302 provides a sealing effect. After assembly, the filling tube 303 facilitates the injection of sealant into the filling groove 301 between the main support frame 201 and the main housing 101, allowing it to solidify. During the injection process, the sealant can be injected inverted to ensure that the sealant fully fills the filling groove 301 and the tiny gaps between the main support frame 201 and the main housing 101, forming a well-sealed waterproof structure. With the cooperation of the waterproof sealing strip 302, the waterproof sealing performance of the support frame assembly 2 and the housing assembly 1 after installation can be significantly enhanced.

[0025] like Figures 1-2 As shown, a heat dissipation fin 4 is fixed at the rear center of the main housing 101, and a protective back cover 5 is installed on the rear outer side of the main housing 101.

The suction pipe 803 is connected to the interior of the main housing 101. One set of suction pumps 802 and suction pipe 803 facilitates the delivery of air from inside the main housing 101 into the dehumidification box 801. The dehumidification box 801 contains activated carbon for dehumidification. The other set of suction pumps 802 and suction pipe 803 facilitates the return of the dehumidified air to the interior of the main housing 101, ensuring the dryness of the interior of the main housing 101 and preventing moisture from affecting the use of the internal LED modules.

[0027] In summary, as Figures 1-5 As shown, this waterproof sealing structure for LED display cabinets, when using LED modules, firstly, the support frame assembly 2 is used to install the LED modules. During assembly, the support frame assembly 2 with the LED modules needs to be installed with the cabinet assembly 1. During this process, the main support frame 201 can be installed inside the main cabinet 101, and the outer edge 202 can be installed inside the front frame 102. At this time, the two waterproof sealing strips 302 can achieve a sealing effect. After assembly, sealant is injected into the filling groove 301 between the main support frame 201 and the main cabinet 101 through the filling tube 303 to solidify it. During the injection process, the injection can be inverted to ensure that the sealant fully fills the filling groove 301 and the tiny gaps between the main support frame 201 and the main cabinet 101, forming a well-sealed waterproof structure.

[0028] During use, the protective back cover 5 can protect the cabinet assembly 1, and the heat conduction plate 203 can perform front-lead heat dissipation. The heat dissipation fins 4 facilitate heat conduction and dissipation from the rear. At the same time, the use of the cooling fan 703 can further enhance the heat dissipation effect. In addition, during use, a set of suction pumps 802 and suction pipes 803 can be used to send the air inside the main cabinet 101 into the dehumidification box 801. The dehumidification box 801 contains activated carbon to dehumidify. Then, another set of suction pumps 802 and suction pipes 803 can be used to return the dehumidified air to the main cabinet 101 to ensure the dryness inside the main cabinet 101 and prevent moisture from affecting the use of the internal LED modules. This completes the use of the waterproof sealing structure for LED display cabinets.
