An ideological and political propaganda device

Abstract

The invention relates to an ideological and political propaganda device, which includes a support and a display screen fixing frame located on the upper part of the support. The support includes a base and a column. The connected rotating shaft, the rotating shaft is connected to the fixed frame of the display screen through the telescopic assembly, the fixed frame of the display screen includes a bearing part and a fixing part, the bearing part includes an outer plate and an inner plate, and the relative contact between the outer plate and the inner plate The surface is corrugated, the heat dissipation plate is arranged in the interlayer between the outer plate and the inner plate, the four edges of the bearing part are respectively rotated and connected to the fixed part, and the two adjacent fixed parts are fixedly connected by connecting fasteners, and the display screen is fixed. There is a display screen embedded in it. The invention has a simple structure, improves students' interest in learning, and can effectively reduce heat transfer impedance and improve heat dissipation performance.

Description

Technical field [0001] The present invention relates to the field of teaching equipment, and more particularly to an ideological and political propaganda device. Background technique [0002] Ideological and politics as a compulsory course for high school students, in addition to the ideological and political propaganda bar in campus, teachers will strengthen ideological and political education and guidance through the ideological and political propaganda columns in campus; however, the ideological and political propaganda used in colleges and universities Most of the promotion effects of the column is not very ideal. The main reason is that the form of propaganda columns is more monotonous, so it is not easy to attract students' interest in reading, and the existing promotional column is fixed or roller blinds, and cannot rotate. The picture can only show one, and the propaganda content is single, and it is not possible to provide people with a full range of viewing, and the pub...

Problems solved by technology

[0002] Ideological politics is a compulsory course for high school students. In addition to classroom teaching and individual tutoring, teachers will also strengthen ideological and political education and guidance through ideological and political propaganda columns on campus; however, the current ideological and political propaganda used in colleges and universities Most of the publicity effects of the column are not very ideal. The main reason is that the form of the bulletin board is relatively monotonous, so it is not easy to arouse the students' interest in reading actively. At present, the existing bulletin board is fixed or rolling, and cannot be rotated. Only one screen can be displayed, and the propaganda content is single, which cannot provide people with a full range of appreciation. In the application, the release of ideological and political propaganda information is subject to certain space restrictions.

[0003] Some of the existing ideological and political propaganda devices use intelligent propaganda, such as display screen propaganda, but the display screen, as an electrical component, will generate heat when it is used. The microscopic voids and uneven holes on the surface will increase the resistance of heat transfer and reduce the heat dissipation performance.
