Description

Fold-proof flattening clamp for engineering cost drawing Technical Field The utility model relates to the technical field of drawing flattening clamps, in particular to an anti-wrinkling flattening clamp for engineering cost drawings. Background In the field of engineering cost, drawings are core data and bear key information such as engineering design, construction planning and the like, and the accuracy and the integrity of the drawings directly influence cost estimation and project pushing. However, the drawings are very easy to wrinkle in the drawing, transferring and storing processes, the wrinkled drawings not only influence visual impression, but also cause blurring of key information, increase difficulty in drawing of engineering cost personnel, and easily cause size misreading and detail omission, so that accuracy of cost calculation is influenced. In addition, when the uneven drawing is scanned and archived, the problems of unclear scanning, image deformation and the like can also occur, which is not beneficial to the digital management and long-term storage of the drawing. In the prior art, part of the device is difficult to ensure that the drawing is stressed uniformly, when the drawing is flattened, the drawing is often folded in the flattening process due to overlarge or undersize local pressure, the integrity and definition of the drawing are affected, and then the accurate calculation of the engineering cost is likely to be interfered. Secondly, the structural design lacks flexibility, and to the drawing of equidimension, can't conveniently carry out the adaptation adjustment, the use limitation is great, can not satisfy the demand of contact multiple specification drawing in the engineering cost work.
