Abstract

An engineering drawing carrying barrel comprises a left paper winding shaft, a right paper winding shaft, a left display frame and a right display frame. The left paper winding shaft is mounted in a left shaft shell, and the left paper winding shaft comprises a left winding core and a left fixed shaft. The left fixed shaft is mounted on the left shaft shell, and the left fixed shaft is sleeved with the left winding core. A paper clamping groove is formed in the left winding core, and the left fixed shaft is connected with a rotary handle, and the rotary handle is mounted on one side of the left shaft shell. The right paper winding shaft is mounted in the right shaft shell, and the right paper winding shaft comprises a right winding core and a right fixed shaft. The right fixed shaft is mounted in the right shaft shell, and the right fixed shaft is sleeved with the right winding core. A paper feeding groove is formed in the right winding core, and a linkage roll shaft is connected between the left fixed shaft and the right fixed shaft. A reset spring is arranged on the left fixed shaft and connected to the inner wall of the left winding core. The rotary handle drives the left paperwinding shaft and the right paper winding shaft, an engineering drawing stably rotates in the display frames, and the drawing can be directly checked through a transparent display board; and carryingis convenient , and the drawing is checked without being touched.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a carrying case for engineering drawings. Background technique [0002] Engineering drawings are related drawings used to express the internal layout, external shape, decoration, structure and construction requirements of buildings. Architectural engineering drawing is based on the principle of projection, according to the drafting standards stipulated by the state, accurately expresses the shape and size of the completed or unfinished construction project on the plane, and at the same time indicates the materials used in the project as well as production, requirements for installation, etc. Engineering drawings are divided into architectural construction drawings, structural construction drawings, and equipment construction drawings. It is the basis for approving construction projects; in production and construction, it is the basis for material preparation and construc...
