Description

Technical Field

[0001] The utility model relates to the technical field of drawing tables, in particular to a drawing table for architectural drawings. Background Art

[0002] Architectural design means that before a building is constructed, the designer, in accordance with the construction task, makes a comprehensive conception of the problems that exist or may occur during the construction process and the use of the building, formulates methods and plans to solve these problems, and expresses them in drawings and documents. This serves as a common basis for material preparation, construction organization, and the coordination and cooperation of various types of work in the production and construction work, so that the entire project can proceed smoothly and in a unified pace within the predetermined investment limit and according to the carefully considered predetermined plan.

[0003] After searching, the Chinese utility model with announcement number CN216059645U discloses a special drawing table for architectural design, including a movable support seat, the upper surface of the movable support seat is fixedly connected with a threaded cylinder, the internal thread of the threaded cylinder is connected with a threaded lifting tube, a drawing table is arranged above the threaded lifting tube, and the outer surface of the drawing table is sleeved with symmetrical sliding pressure plates, each of which is fixedly installed with a handle on the upper surface, and each of which is provided with a symmetrical sliding hole on the bottom surface, and each of which is slidably connected with a sliding rod inside. The design structure of the utility model is reasonable. It arranges two sliding pressure plates on the drawing table, and utilizes the slide groove and the slider to cooperate with the sliding rod, so that the sliding pressure plate can move left and right, which is convenient for adjusting the position according to the size of different drawings.
