The invention discloses a display board for engineering design and belongs to the technical field of display boards. The display board is characterized in that the display board comprises a display board body, a rainproof cover body and a controller box, wherein the left side and the right side of the display board body are both provided with fixing frames, and opposite sides of the two fixing frames are both provided with two uniformly distributed leaflet placing boxes; lower end faces of the two fixing frames are fixedly connected with electric control adjusting supporting legs, the left side and the right side of the lower portion of the display board body are each provided with two symmetrically-distributed telescopic reinforcing ribs, the display board body is formed by connecting two outer display boards, two middle display boards and an inner display board in a sliding and sleeving mode, and the display area of the display board body can be adjusted; a loudspeaker in front of the controller box facilitates voice propaganda of the content of the display board, a leaflet placement box facilitates placement of leaflet in the propaganda placement groove and facilitates browsing and viewing of a viewer, and the protection cover has the rainproof and dustproof effects and prevents rainwater and dust from entering the propaganda placement groove.
Description
technical field [0001] The invention relates to the field of engineering design, in particular to a display board for engineering design. Background technique [0002] Exhibition board refers to the plate-shaped medium used for publishing and displaying information, including paper, new materials, metal materials, etc. The screen of the exhibition board is made of adhesive backing material, which can be selected according to the brightness of the use site and personal preferences. It is used for engineering design. The exhibition boards are mainly displayed with design, planning and related information content. [0003] Existing display boards have simple structure, low usability, and inconvenient adjustment. If they are too small, they will not be used, and if they are too large, they will be inconvenient for transportation and storage, and occupy a large space. Contents of the invention [0004] The invention provides a display board for engineering design, which aims t...
