Description

Technical Field

[0001] The utility model relates to the technical field of electronic billboards, in particular to a device for preventing an elevator electronic billboard from tipping over. Background Art

[0002] Elevator advertising is a new type of advertising media. It refers to advertising carriers produced and published on the inner walls of elevators in urban buildings. Most of them are achieved by installing billboards in the elevator. In order to prevent passengers from getting tired of watching, some elevators use an electronic screen billboard inside. The billboards are installed by pasting, which is prone to tipping and falling.

[0003] When an elevator goes up and down vertically, there will most likely be a phenomenon of weightlessness, and some elevators will vibrate, which can cause billboards to fall and easily injure passengers while they are riding the elevator. Not only will this fail to achieve the advertising effect, it will also lead to complaints from passengers, greatly reducing the economic benefits of electronic billboards. Utility Model Content
