Drawing paper placing device for civil engineering

Abstract

The invention discloses a drawing paper placing device for civil engineering. The device includes a fixing base and four rotating plates, a bearing is installed in the middle of the top surface of thefixing base, and a shaft rod is assembled in the bearing; a hollow cylinder body is installed on the shaft rod, and a circular plate is installed at the bottom of the hollow cylinder body; the four rotating plates are annularly installed on the hollow cylinder body at equal intervals, a first circular rod is installed on the top of one side surface of each rotating plate, and the first circular rods are sleeved with movable plates; pressing plates are installed on both sides of the bottom of each movable plate, a second circular rod is installed in the middle of one side surface of each rotating plate, and grooves are formed in the annular surfaces of the second circular rods at equal intervals. The device is convenient to use, the placement effect is great, the flatness of placed drawingpaper is ensured, the situation that the information content is blurred since the drawing paper is damped can be avoided, users can use the device to mark the placed drawing paper conveniently, and more convenience is provided for the users to quickly and accurately take the drawing paper.

Description

technical field [0001] The invention relates to a drawing placing device, in particular to a drawing placing device for civil engineering, belonging to the field of civil engineering. Background technique [0002] During the construction process, the construction unit will receive many drawings issued by the design institute. These drawings need to be used repeatedly during the construction process. However, the storage and storage of the drawings on the construction site do not attract attention. There is no classification, and repeated searches by many people during construction will inevitably lead to damage, mess and even loss of drawings. If the drawings are folded and stored, the handwriting will easily be blurred. Moreover, there is often more than one set of drawings, and multiple drawings are needed to fully express the design ideas. If they cannot be classified and stored, it will have some impact on the work of the construction personnel on site. How to classify ...

Problems solved by technology

[0003] The protection effect of the drawing placement device in the prior art is not good, and it is easy to cause the drawing to be damp and cause the confidence content to be blurred. The ordinary placing device is not conducive to maintaining the flatness of the drawing and appears messy. The placement of marks is not conducive to users' quick and accurate access to drawings
