Display board for convention and exhibition

Abstract

The invention relates to the technical field of display boards, and in particular relates to a display board for convention and exhibition. The display board comprises a main support tube, a display mechanism, a wind driven generating mechanism, a support mechanism and a protection mechanism. For the display board for convention and exhibition, a poster is pasted to a rear cover board, the protection mechanism is mounted in front of the rear cover board, when light rays are strong, a second take-up mechanism is started so that a first permeable membrane with relatively poor light penetrating ability covers outside the poster, thus the illumination intensity entering the poster is weakened, therefore, the light-reflecting degree of the poster is reduced, further, pedestrians can clearly seethe information of the poster, when the light rays are common, a first take-up mechanism is started so that a second permeable membrane with strong light penetrating ability is placed outside the poster, meanwhile, at night, an LED lamp can be turned on for realizing illumination, thus no matter under any light ray condition, the pedestrians can clearly see the information on the display board; through the wind driven generating mechanism, electricity generating can be realized by utilizing the outdoor wind energy, and thus the repeated charging of a user or the arrangement of an independentcircuit is not needed.

Description

technical field [0001] The invention relates to the technical field of display, in particular to an exhibition display board. Background technique [0002] When merchants need to promote products intensively, they often organize an exhibition to display products. In the exhibition, many display boards are needed to display relevant product information, and posters are pasted on the display boards to facilitate exhibitors to understand. [0003] Most of the current display boards are only satisfied with the use under normal lighting. When the light is strong, the posters will reflect light, making it very dazzling for passers-by to see the display content; in order to illuminate the posters, the display boards are often equipped with a separate When the battery or line is used outdoors, it will be very difficult to repeatedly charge and lay the line, which cannot effectively meet the needs of outdoor use; the support strength is not high enough, and when wind resistance is re...

[0003] Most of the current display boards are only satisfied with the use under normal lighting. When the light is strong, the posters will reflect light, making it very dazzling for passers-by to see the display content; in order to illuminate the posters, the display boards are often equipped with a separate When the battery or line is used outdoors, it will be very difficult to repeatedly charge and lay the line, which cannot effectively meet the needs of outdoor use; the support strength is not high enough, and when wind resistance is required, a stone will often be pressed against the bottom support plate , and due to the lack of a specific placement position, the effect of stone aggravation is not good, and the display card is still easy to dump
