Description

Technical Field

[0001] The utility model relates to the technical field of drawing display, in particular to a drawing display device for engineering budget construction. Background Art

[0002] During the process of engineering construction and engineering budgeting, there is a need to display engineering drawings. Since drawings are generally large, they are generally stored in rolls. After the rolled drawings are unfolded again, they still have a tendency to bend at both ends. Therefore, a drawing display device is needed to flatten them. After searching, a Chinese patent with publication number CN215423677U discloses a drawing display device for engineering budgeting construction, including a base plate and a first telescopic cylinder. There are two base plates, the first telescopic cylinder is fixedly connected to a side surface of the base plate, and a plurality of universal wheels are arranged on the lower surfaces of the two base plates. A first telescopic column is arranged at one end of the first telescopic cylinder, and the first telescopic cylinder is slidably matched with the first telescopic column. A second rotating shaft is arranged at one end of the two base plates. A slot is provided with a second rotating shaft inside the second rotating shaft slot, the second rotating shaft is rotatably matched with the second rotating shaft slot, a second rotating block is provided on the circumferential side of the second rotating shaft, one end of the second rotating block is fixedly connected with a main telescopic column, one end of the main telescopic column is provided with a main telescopic tube, the main telescopic column and the main telescopic tube are slidably matched. When in use, the drawing needs to be unfolded first, and the four corners of the drawing are clamped by four fixing clips for display. This method of unfolding the drawing first and then fixing the four corners not only has low display efficiency, but also easily causes the drawing to be torn or creased when unfolding and fixing. In addition, in the actual budget and construction process, the drawing needs to be unfolded multiple times, which can easily cause irreversible damage to the drawing. Utility Model Content
