Description

Technical Field

[0001] The utility model relates to the technical field of LED display screens, and in particular to an outdoor LED display screen. Background Art

[0002] LED displays are widely used outdoors due to their high brightness, bright colors and good weather resistance. For example, in tourist attractions, LED displays can be used to publish tourist information, scenic spot introductions and event arrangements, etc., providing tourists with convenient information services; in addition, LED displays are often used as billboards to display advertisements for various products, brands or events;

[0003] In order to ensure that outdoor LED displays can work properly in various weather conditions, they are usually waterproofed to have a certain waterproof function; however, even so, there are still some problems with the waterproof performance of outdoor LED displays; general outdoor LED displays protect the internal circuit from the external environment through the overall protection of the shell, but the gaps at the joints of the shell are prone to rainwater infiltration, especially when exposed to rain for a long time;

[0004] Although fillers are added to the gaps to improve sealing, they may age, deform, or fall off under long-term use and severe weather conditions, which will further reduce the sealing effect of the display. When rainwater can directly contact the internal components of the display, it may cause various failures.

[0005] In addition, in order to achieve a better sealing effect, some LED display screens adopt stricter sealing measures, but this may lead to another problem - poor heat dissipation; due to the tight sealing, the heat inside the display screen is difficult to dissipate effectively, especially when the display screen is running for a long time, the accumulation of internal temperature will cause the LED lamp beads and electronic components to overheat, thus affecting the stability and life of the display screen. Utility Model Content

[0006] The problem solved by the utility model is that a general outdoor LED display screen protects the internal circuit from the influence of the external environment through the overall protection of the shell, but the gaps at the joints of the shell are easy to cause rainwater to penetrate, especially when exposed to rainwater for a long time; the strict sealing measures taken to improve the sealing effect may lead to poor heat dissipation.

[0007] In order to solve the above problems, the utility model provides an outdoor LED display screen, comprising a flip frame, a connecting frame and a display screen assembly; the top of the flip frame is fixedly connected to the top of a storage box, the bottom of the flip frame is fixedly connected to one side of the connecting frame, and the other side of the connecting frame is fixedly connected to one end of the display screen assembly; the display screen assembly comprises an installation box, a display screen, a dustproof module and a cooling fan; two display screens are respectively arranged on both sides of the installation box, a plurality of cooling fans are respectively arranged at the bottom of the installation box, two dustproof modules are respectively arranged on both sides of the installation box, and the top of the installation box is fixedly connected to one end of the connecting frame.
