A drawing and measuring device suitable for road design in windy and sandy areas

Abstract

The invention discloses a painting and measuring device for highway design in the technical field of highway design, which is suitable for road design in windy and sandy areas. Hinged sand-proof shell, the inner middle of the U-shaped seat is slidably connected with two sets of connecting guide plates, a transparent plate is fixedly arranged between the two sets of connecting guide plates, and the top of the organ-type dust-proof folding cloth is located in the U-shaped seat. One inner; cleaning automatic assembly, the cleaning automatic assembly is arranged on the left side of the bottom of the support plate, the present invention is provided with a painting assembly, the hand-held painting pen passes through the sleeve to draw the paper in the sand-proof shell, and the organ-type dust-proof folding The setting of the cloth is convenient for the user to hold the drawing pen and move the transparent plate to the left or right to draw, and the paper in the sand-proof shell will not be affected by the external wind and sand, thus avoiding the paper being soiled or damaged. The quality of the user's painting.

Description

technical field [0001] The invention relates to the technical field of highway design, in particular to a drawing and measuring device for highway design suitable for sandstorm areas. Background technique [0002] In the process of highway design, it is usually necessary to use measuring equipment to measure the highway, obtain the basic data required for highway design, and then manually draw on paper. [0003] However, the paper in the existing painting measuring device is generally fixed on the drawing board for the user to draw. The method is easily affected by sandstorms. Sandstorms can easily cause the paper on the exposed drawing board to become dirty, and even cause the paper to be damaged. On the one hand, the dirty paper seriously affects the quality of the user's painting, and on the other hand, it is inconvenient for the user. The later reference to the drawn drawings will have a certain impact on the road design work. For this reason, we propose a drawing and m...

[0003] And the paper in the existing painting measurement device is generally fixed on the drawing board for the user to draw, and the drawing paper is mostly fixed on the drawing board, and the drawing board is mostly exposed outside, and for the highway in the sandstorm area, this kind of painting The method is easily affected by wind and sand. Wind and sand can easily cause the paper on the exposed drawing board to become dirty, and even cause the paper to be damaged. On the one hand, the dirty paper seriously affects the quality of the user's drawing, and on the other hand, it is inconvenient for the user. The drawings drawn later will have a certain impact on the road design work. Therefore, we propose a painting measuring device for road design in windy and sandy areas
