An ideological and political propaganda board that is windproof and easy to replace

Abstract

The invention discloses a windproof and easy-to-replace ideological and political propaganda bar, which adopts a vertical and approximately horizontal conversion structure that is electrically driven on both sides of the bar, which can facilitate the propaganda bar from vertical to approximately horizontal, so as to facilitate the To prevent being blown down by the wind in windy weather, or to easily replace the promotional pages in the fence, there is no need to stretch the soft propaganda pages vertically, and the fence will automatically return to the position, from approximately horizontal to vertical, It is convenient to continue to play the role of publicity after the strong wind or the replacement of the promotional page, that is to say, the two problems of windproof and convenient replacement can be solved through this structure, and the adaptability is good.

Problems solved by technology

[0002] As a place for teaching and educating people in schools, the bulletin board is an indispensable tool, especially the ideological and political education is an important work that needs to be carried out for a long time. The ideological and political bulletin board can effectively help students establish a correct outlook on life and values, so Ideological and political bulletin boards are generally set up all over the campus, such as in flower beds on both sides of the road, around the campus landscape belt, etc., but because the general bulletin boards use a structure with two supporting legs under a frame, the windproof ability is poor , in windy weather, it is easy to be blown down, or even blown away, and it is easy to injure others at this time. This has indeed been encountered in daily life, and I was shocked by it, so the idea of ​​​​improvement was born, and After consulting the information, it is found that the predecessors have indeed done a lot of work. For example, the application number is "201711009504X", and the patent name is "A Propaganda Column for Windbreak and Sand Fixation". The board is equipped with a torsion spring at the hinge to adapt to the blowing direction of the wind and reduce the area where the strong wind acts on the bulletin board. However, the disadvantage of setting multiple rotating boards here is that it is difficult to paste a large-scale publicity page. Under the action of strong wind, multiple rotating plates rotate separately, which can cause the problem of tearing the leaflet. The inspiration from this patent is to set the rotating plate to facilitate pasting larger leaflets, but this also brings new The problem is that the size of the rotating plate is not small, and it is easy to flap back and forth against the road during the rotation process, which is very easy to injure pedestrians, so I further consider how to absorb the advantages of this windproof, and can effectively avoid injuring pedestrians
