Description

Technical Field

[0001] The utility model relates to the technical field of news dissemination, in particular to a display device for news dissemination. Background Art

[0002] News is a name for information disseminated through media channels such as newspapers, radio stations, broadcasts, and television stations. It is a genre that records society, disseminates information, and reflects the times. The concept of news can be divided into broad and narrow meanings. In the broad sense, all common texts except for comments and special articles published in newspapers, radio, the Internet, and television belong to the category of news, including news, communications, features, sketches, etc. News in a narrow sense refers specifically to news, which uses a general narrative method and relatively concise and concise text to quickly and timely report recent and valuable facts at home and abroad so that others can understand them. Each news generally includes six parts: title, head, introduction, main body, background, and conclusion.

[0003] In the news media industry, information data is usually needed, and in order to facilitate the display of these information data, news communication display devices are needed.

[0004] A mobile news dissemination device with the patent publication number CN218119313U states that "the utility model drives the driving gear to rotate by the driving motor, thereby driving the driven gear and the rotating shaft to rotate by the gear chain, and finally driving the walking wheel forward, so that the news dissemination device can display the news in a straight line path in a specific occasion, and the infrared position sensor can detect whether there is an obstacle in front and stop in time, thereby improving the efficiency of dissemination, expanding the scope of dissemination, and no manual promotion is required, saving time and effort";

[0005] However, the above scheme still has certain shortcomings when used. For example, the comparison scheme does not have a self-locking structure, which causes the device to slide easily due to accidental touch after being moved to the designated position, resulting in deviation in the display position and even the device colliding with other people or objects, thereby greatly reducing the practicality and safety of the device.
