Description

Technical Field

[0001] The utility model belongs to the technical field of smart cities, and in particular relates to a mobile publicity device for smart cities. Background Art

[0002] Smart city originated from the field of media. It refers to the use of various information technologies or innovative concepts to connect and integrate the city's systems and services to improve the efficiency of resource utilization, optimize urban management and services, and improve the quality of life of citizens. Smart city publicity devices are devices used by smart cities to publicize city characteristics and display announcements. They are mainly used for the publicity of city announcements.

[0003] For example, the Chinese patent with the publication number CN212484869U discloses a mobile propaganda device for smart cities, which relates to the field of smart city technology, including a fixed frame, a top cover, a threaded bolt, a fixed plate, a threaded column, a threaded barrel, a sleeve, a threaded ring, a threaded rod, a reinforcement barrel, a docking block, a docking barrel, an extrusion rod and a conical block. The top of the fixed frame is nested with a top cover, and the bottom of the fixed frame is embedded with two threaded bolts. The threaded bolts are all movable and penetrate the fixed plate. The bottom of the fixed plate is fixedly connected with a threaded column, and the threaded column is threadedly embedded in the middle of the threaded barrel. The bottom of the threaded barrel is fixedly connected with a sleeve. The threaded rod in the utility model moves downward in the threaded ring, and the threaded rod is inserted deeper into the soil, so that the reinforcement barrel and the conical block enter a deeper position in the soil. The soil will fill the top of the reinforcement barrel, thereby preventing the reinforcement barrel from falling off from the soil, and can be fixed very firmly on the ground. Compared with traditional propaganda devices, it does not require the use of concrete and has the advantages of easy installation and firm fixation.

[0004] This patent has some shortcomings when used, such as: the propaganda device in this patent is fixed to the ground, and the main part of the propaganda device cannot be rotated, so people cannot view the propaganda page of the propaganda device from the back or oblique side, which is not conducive to the propaganda of city announcements; in addition, the propaganda device in this patent cannot adjust the appropriate installation height according to the needs of users, and cannot meet the needs of people of different heights. When people with shorter heights view the propaganda device, the fonts on the upper part of the propaganda page or the propaganda page cannot be seen clearly due to the viewing angle. In view of this, we propose a smart city mobile propaganda device. Utility Model Content
