A display board for an exhibition

Abstract

The invention relates to the technical field of display boards, specifically a display board for exhibitions, including a main branch pipe, a display mechanism, a wind power generation mechanism, a support mechanism and a protection mechanism; A protective mechanism is installed in front of the board. When the light is strong, the second winding mechanism is activated so that the first transparent film with relatively poor light transmission ability covers the outside of the poster, so that the intensity of light entering the poster becomes weaker, and then Reduce the degree of reflection of the poster, so that passers-by can clearly see the poster information. When the light is relatively normal, start the first winding mechanism to place the second transparent film with strong light transmission ability on the outside of the poster, and turn on the LED at night The lights are used to illuminate, so that no matter what the light conditions are, pedestrians can clearly see the information on the display board; through the wind power generation mechanism, the outdoor wind energy can be used to generate electricity, so that users do not need to recharge repeatedly or set up separate lines.

Description

technical field [0001] The invention relates to the technical field of display, in particular to an exhibition display card. 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 req...

Problems solved by technology

[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
