[0038] Working principle of the present invention:

[0039] When the device is in use, firstly, the hanging plate 24 is placed upwards at the position where it needs to be installed, so that it is located between the two installation blocks 26, and then the rotating knob 28 is turned, and the rotating knob 28 drives the bidirectional screw rod 27 to rotate, and the bidirectional screw rod 27 drives the two adjustment blocks 25 to move, so that the two installation blocks 26 are close to each other and squeezed to complete the quick installation, and at the same time, the dustproof glass 14 is opened and advertisements, promotional posters, etc. are posted in the area of ​​the LED lamp tube 13;

[0040] After the installation is completed, in daily use, one of the power switches 7 is connected to the information frame 5 to power the LED lamp tube 13 in the information frame 5 for lighting and to set a propaganda poster on its surface for advertising in public places. When an emergency situation requires an alarm, the controller 9 first controls the drive motor 11 to rotate, the drive motor 11 drives the primary bevel gear 10 to rotate, the primary bevel gear 10 drives the secondary bevel gear 12 to rotate, the secondary bevel gear 12 drives the drive rod 3 to rotate, the drive rod 3 drives the two primary rotating rods 4 to rotate, the primary rotating rod 4 drives the information frame 5 to move, and with the assistance of the secondary rotating rod 6, drives the information frame 5 to flip horizontally 180°, so that one side of the information display screen 15 faces outward. When the information display screen 15 completes the flip, the electrode 8 in the power supply slot will reconnect the power switch 7, thereby powering the information display screen 15, so that the alarm information is displayed on the information display screen 15, and the controller 9 will start the alarm light 17 to continuously flash the alarm;

[0041] During the flipping process of the information display screen 15, the driving rod 3 simultaneously drives the two three-stage bevel gears 18 to rotate, the two three-stage bevel gears 18 drive the two four-stage bevel gears 21 to rotate, the two four-stage bevel gears 21 respectively drive the two transmission rods 20 to rotate, and the two transmission rods 20 respectively drive the lifting threaded rods 22 to rotate, so that the two lifting threaded rods 22 are lifted and lowered in the two lifting tubes 23, thereby driving the entire mounting plate 2 to move downward, thereby lowering the display height, making the alarm prompt more eye-catching and easier to be found, thereby achieving the effect of alarming special groups of people.

[0042] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
