Description

Technical Field

[0001] The utility model relates to the technical field of drawing measurement, in particular to a drawing measurement device. Background Art

[0002] With the development of society, construction work is also in full swing. When managing construction projects, it is necessary to construct the building according to the dimensions of the drawings. In order to ensure the precision of the building after construction is completed, it is necessary to use measuring tools to measure the dimensions of the drawings to ensure the accuracy of the drawing dimensions.

[0003] Since construction drawings are numerous and large in size, they are usually folded or rolled up for transportation or storage. When the drawings need to be measured, they usually need to be unfolded first, laid flat on a table, and then measured with a ruler. During the measurement process, the drawings are prone to warping and curling, resulting in inaccurate measurements. When the device body is not in use, dust easily adheres to the device body, requiring frequent cleaning, which reduces work efficiency. Therefore, the existing device needs to be improved to meet actual needs. Utility Model Content
