Manual mechanical drawing table

Abstract

The invention discloses a manual mechanical drawing table, which comprises a main body fixing plate, a storage slot is installed in front of the upper end of the main body fixing plate, and a left connecting block is arranged on the left side of the rear end of the storage slot, and both sides of the lower end of the main body fixing plate are Both are provided with a first support frame, and a second support frame is installed on the outside of the first support frame, and a fixing bolt is arranged inside the second support frame, and the front end of the fixing bolt is connected with the first support frame, and the upper left side of the drawing board The side is connected with a left end fixed rod, and the upper right side of the drawing board is connected with a right end fixed rod. The manual mechanical drawing table can enable students to draw manually without bending over for a long time. The height of the drawing table and the angle of the drawing board can be adjusted according to the height of the students and their drawing habits. In addition, rubber crumbs do not always remain on the drawing surface to stain the drawing, and drawing tools such as T-squares and compasses can also be neatly placed for easy access.

Description

technical field [0001] The invention relates to the technical field of teaching aids for students, in particular to a manual mechanical drawing table. Background technique [0002] The Department of Mechanical Engineering includes seven majors, including technology, automation, manufacturing, service marketing, numerical control technology, and engineering machinery. An indispensable course for students in the Department of Mechanical Engineering is mechanical drawing, and mechanical drawing includes manual drawing. A common method for students to draw by hand is to lay the drawing paper on the desktop for drawing. [0003] Commonly used manual drawing methods need to bend over for a long time, which is easy to cause students’ waist pain, and rubber crumbs are easy to accumulate on the drawing surface or scattered on the ground. Commonly used drawing tools such as T-square, compasses, eraser and pencil have nowhere to go release phenomenon. Contents of the invention [0...
