A led gear screen that can automatically control the rotation

Abstract

The invention discloses an LED gear screen capable of automatically controlling rotation. The structure includes a gear screen main body, an inner connecting column, a connecting block, and an inner fixing seat. The gear screen main body is mechanically connected with the inner connecting column, and the inner connecting column is far away from the gear screen main body. There is a connection block on one end of the device, and the beneficial effect of the present invention is that the gear display screen is driven to rotate by external mechanical force, and the electric seat on the inner ring is driven to move accordingly. When the electric seat is connected with the conductive rod, the conductive rod and the conductive rod The layers fit together, so that the conductive rod gets electric energy and the warning light gets electric energy to light up through the reinforcement ring. At this time, the gear display stops rotating. The switch between on and off, and the corresponding stop or run of the corresponding gear display screen alternately, make the display screen more conspicuous by flickering, and stop the display screen to facilitate people to watch the advertising content and improve the publicity effect.

Description

technical field [0001] The invention relates to the field of LED screens, in particular to an LED gear screen capable of automatically controlling rotation. Background technique [0002] Traditional billboards are set up in the form of paper frames or directly in the form of iron plates, and are installed at high places, which is easy to be eye-catching and have a publicity effect, but such billboards are easy to be blown off when encountering a typhoon , there is a big safety hazard, so the LED display is developed, the advertising content is displayed on the display, and the display is embedded and installed on the wall to solve the safety hazard caused by the falling of the billboard. The current automatic control The rotating LED gear screen has the following defects: [0003] The existing LED gear screen is set up to drive the first gear screen and the second gear screen to rotate 360 ​​degrees by setting up a motor to realize the omni-directional rotation of the gear ...

Problems solved by technology

[0002] Traditional billboards are set up in the form of paper frames or iron plates, and are installed at high places, which is easy to be eye-catching and have a publicity effect, but such billboards are easy to be blown off when encountering a typhoon , there is a large safety hazard, so the LED display is developed, the advertising content is displayed on the display, and the display is embedded and installed on the wall to solve the safety hazard caused by the falling of the billboard. The current automatic control The rotating LED gear screen has the following defects:

[0003] The existing LED gear screen is set up to drive the first gear screen and the second gear screen to rotate 360 ​​degrees by setting up a motor, so that the gear screen can rotate in all directions and have an animation effect. Watching, the advertising effect of the LED display is greatly reduced
