The invention discloses a retractable display board for engineering design, comprising an upper horizontal board and a lower horizontal board. An upper chute is provided below the upper horizontal board, and a lower chute is provided above the lower horizontal board. Three horizontal sliders are slidably connected inside the lower chute, the inner sides of the horizontal sliders are fixedly connected with rotating hinges, and the two rotating hinges on the upper left side are rotatably connected with left tilt rods, and the left tilt rods are respectively connected with the lower right side. The two rotating hinges are rotatably connected, and a right tilt rod is rotatably connected above the two rotating hinges on the lower left side. Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention has a simple structure, is easy to use, can be assembled and disassembled quickly during demonstration and explanation, and can fix the engineering design drawings well. It can be disassembled quickly, so it is convenient to carry, and has strong practicability especially when it is used outdoors.
Description
technical field [0001] The invention relates to a display board, in particular to a shrinkable display board for engineering design. Background technique [0002] Engineering design refers to the entire activity process of providing design documents and drawings with technical basis for the construction of engineering projects. The bond of transforming into productivity is the key link in dealing with the relationship between technology and economy, and the key stage of determining and controlling the project cost. Whether the engineering design is economical and reasonable is of great significance to the determination and control of the construction project cost. [0003] Engineering design is the activity of comprehensively analyzing and demonstrating the technical, economic, resource, environmental and other conditions required for construction projects, compiling construction project design documents, and providing related services according to the requirements of const...
