Exhibition halladvertising screen capable of realizing movement by utilizing magnetic repulsion

Abstract

The invention relates to the technical field of advertising, and discloses an exhibition hall advertising screen capable of realizing movement by utilizing magnetic repulsion, which comprises a display screen, a circuit wire is arranged in the display screen, a picture tube is fixedly connected to the outer side of the circuit wire, a connecting rod is fixedly mounted on the outer side of the display screen, a spring rod is arranged in the connecting rod, a semicircular magnetic plate is fixedly mounted on the inner side of the connecting rod, and a magnetic mounting column is arranged in thesemicircular magnetic plate. According to the exhibition hall advertising screen, the display screen rotates to synchronously drive a connecting rod and an outer gear connected with the top end of therod body of the connecting rod to rotate synchronously, then the outer gear drives an inner gear meshed with the outer gear to rotate synchronously, and along with rotation of the inner gear, the purpose of charging a charging power source is achieved; and the electric quantity of the charging power supply is supplied to the display screen for use, thereby realizing recycling of resources.

Description

technical field [0001] The invention relates to the technical field of multimedia advertising, in particular to an advertising screen for an exhibition hall that uses magnetic repulsion to realize movement. Background technique [0002] Multimedia applications are very extensive, such as commercial advertising, teaching, entertainment, engineering and other industries, in some high-end exhibition halls will be placed with multimedia advertising screens to promote products, etc., but the current advertising screens lack new ideas and are all the same The installation is hung on the wall, it is difficult to attract the attention of users, and it lacks innovation. Therefore, we propose an advertising screen for exhibition halls that uses magnetic repulsion to achieve movement. Through rotatable multi-angle rotation, a great interaction with users is increased, and users' interest in participating in the exhibition is enhanced. Multi-directional viewing, convenient for visitors...
