Description

Technical Field

[0001] The utility model belongs to the technical field of display screens, and specifically relates to a rotary LED display screen. Background Art

[0002] An outdoor LED display screen is a display screen that uses a semiconductor light-emitting diode display method to display various information such as text, graphics, images, animations, market conditions, videos, and video signals. In order to enable the content of the LED display screen to be viewed from a long distance, the display area of the LED display screen is generally relatively large. In addition to increasing the weight, a larger area will also bring a greater side effect - an increase in the windward area, which poses high requirements for the fixing brackets of the outdoor LED display screen.

[0003] In the transportation field, in order to provide the best viewing angles for drivers and pedestrians, LED traffic guiding screens usually adopt two installation methods: single cantilever and gantry, suspending the LED traffic guiding screen above the lane; in this installation method, since the LED traffic guiding screen and the vertical pole are fixed at one end (the single cantilever is fixed on the side and the gantry is fixed at the bottom), under the action of the lever arm, the destructive force on the vertical pole and the ground foundation is greater; especially in coastal areas where typhoons often strike, in order to ensure safety, it is necessary to increase the steel consumption of the cantilever and gantry and increase the volume of the foundation in actual applications, resulting in a great waste of resources. Therefore, it is necessary to make improvements. Summary of the Utility Model
