Abstract

The invention relates to a construction site drawing containing device, in particular to a portable telescopic drawing support. The problems that due to the fact that existing drawing placing is manually operated, time and labor are consumed, and construction efficiency is influenced are solved. The portable telescopic drawing support comprises an elliptical annular support core, five cylindrical hinges are arranged on the support core, two symmetric cylindrical hinges are connected with telescopic support arms, the other three evenly-arranged cylindrical hinges are connected with telescopic support legs, and drawing clips are arranged at the outer ends of the two telescopic support arms. The portable telescopic drawing support is reasonable and reliable in structural design, the problem that labor intensity is large due to manual operation is solved, supporting is stable, and normal use is not influenced even though it is windy. Meanwhile, unfolding and folding are convenient, carrying is facilitated, and the advantages of being simple in structure, convenient to process and low in cost are achieved.

Description

technical field [0001] The invention relates to a drawing placement device at a construction site, in particular to a portable telescopic drawing support. Background technique [0002] Various projects in the construction period, such as transmission line construction, building construction, and water conservancy construction, all need to develop relevant drawings on the construction site, and discuss issues by comparing drawings and objects. For the layout of the blueprints, not only is there no table, but even a platform above the ground is difficult to have. [0003] Now the drawing is unfolded and placed, and the four corners of the drawing are usually supported by two people, which is labor-intensive and seriously affects the construction efficiency. Contents of the invention [0004] The present invention provides a portable telescopic drawing support for solving the problem of time-consuming and labor-intensive influence on construction efficiency caused by manual ...
