LED display screen with automatic protection cover

Abstract

The invention discloses an LED display screen with an automatic protective cover, which comprises a limiting mechanism, the limiting mechanism comprises a bottom frame, two mounting seats are fixedly connected to the inner bottom surface of the bottom frame, a linkage rod is rotatably arranged between the opposite outer surfaces of the two mounting seats, the outer surface of the linkage rod is sleeved with two first linkage bevel gears and a worm gear, and the worm gear is fixedly connected with the bottom frame; limiting plates are fixedly connected to the top of the bottom frame. During use, equipment can be stably arranged at a designated use position through the bottom frame, then the motor is controlled to be started, then the motor can effectively drive the second linkage shaft to rotate by driving the bevel gear, and then the second linkage shaft can effectively drive the first linkage shaft to rotate through the linkage gear; and then the first linkage shaft can effectively drive the linkage rod to rotate through the worm and the worm gear, and then the rotating linkage rod can effectively drive the movable threaded rod to rotate through the first linkage bevel gear and the second linkage bevel gear.

Description

Technical field [0001] The present invention belongs to the technology field of display screen protection equipment, which is specifically a LED display with an automatic protective cover. Background technique [0002] The LED display is a tablet display, which consists of small LED module panels to display various information such as text, images, and videos. It has the advantages of colorful color, wide dynamic range, high brightness, long life, stable and reliable work. The LED display is widely used in commercial media, cultural performance markets, stadiums, information dissemination, press release, securities transactions, etc., which can meet the needs of different environments. [0003] However, among the existing technologies, the existing Outdoor LED display is mostly installed directly and set at the specified use location, which will cause the external environment to directly affect the LED display. The actual service life is shortened, which also affects the efficien...

Problems solved by technology

[0003] However, in the prior art, most of the existing outdoor LED display screens are directly installed at the designated location, which leads to the external environment can directly affect the LED display screen, and it is easy to cause the LED display screen to be damaged after being used and idle for a long time. The actual service life is shortened, and at the same time, it affects the efficient reading of the content displayed on the LED display, resulting in poor actual use of the device
