Description

Technical Field

[0001] The utility model relates to the field of waterproof boxes, in particular to a double-layer waterproof box structure. Background Art

[0002] LED electronic display is a display method that controls semiconductor light-emitting diodes. It is composed of tens of thousands to hundreds of thousands of semiconductor light-emitting diode pixels arranged evenly. It uses different materials to produce LED pixels of different colors to display text, graphics, images, animations, market conditions, videos, video signals and other information. When LED displays are installed outdoors, they generally need to be installed in conjunction with a waterproof box.

[0003] For example, the patent with authorization announcement number CN218299311U discloses a waterproof box for an outdoor LED display screen, including a rear shell and a transparent front panel connected to the front opening of the rear shell by a hinge, and a plurality of heat dissipation holes with shutter structures are arranged on the upper and lower sides of the left and right sides of the rear shell, and also includes an air outlet hood, an air outlet fan and an air inlet hood; the air outlet hood is installed on the inner side of the upper heat dissipation hole, the air outlet fan is installed on the air outlet hood, and the air inlet hood is installed on the inner side of the lower heat dissipation hole.

[0004] Although the heat dissipation holes, the first air outlet holes and the air inlet holes of the above-mentioned patent are all louver structures, which improve the waterproof performance; when used outdoors, there will be strong winds and rains, which can easily cause rainwater to blow obliquely into the waterproof box from the louver structure. The evaporation of these rainwater can easily cause short-circuit damage to the components inside the device, thereby reducing the service life of the outdoor small-pitch LED display box.

[0005] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Utility Model Content
