A display device for mechanical design that is convenient for placing drawings

Abstract

The invention belongs to the technical field of drawing display, and particularly relates to a display device providing convenience for placing a drawing for mechanical design. For the problem that adrawing display fixing device for mechanical drawing teaching is inconvenient to design and needs to be operated by many people, the following scheme is proposed that the device comprises a placing plate, wherein the outer wall of the top of the placing plate and the outer wall of the bottom of the placing plate are welded with a first connecting transverse plate and a second connecting transverseplate respectively, a first sliding groove is formed in the outer wall of one side of the first connecting transverse plate, the inner walls of the opposite sides of the first sliding groove are welded with a same sliding rod, the outer wall of one side of the sliding rod is slidably connected with a first moving sliding block, the specification of the first moving sliding block is matched with the specification of the first sliding groove, a second sliding groove is formed in the outer wall of one side of the second connecting transverse plate, and the inner wall of one side of the second sliding groove is slidably connected with a second moving sliding block. The display device providing convenience for placing the drawing for the mechanical design not only reduces the labor intensity,prevents the occurrence of wrinkles and breakage from affecting the repeated use of the drawing, but also plays a certain role in protecting the drawing, thereby improving the drawing display effect.

Description

technical field [0001] The invention relates to the technical field of drawing display, in particular to a display device for mechanical design that is convenient for placing drawings. Background technique [0002] Mechanical drawing is a discipline that uses drawings to accurately represent the structural shape, size, working principle and technical requirements of machinery. The teaching requirements in the field of mechanical drawing are also constantly improving. In teaching, not only should use textbooks, but also use various drawings as reference materials for teaching, so that students can observe and understand mechanical drawing more directly. However, due to lack of suitable The display stand brings inconvenience to teaching. It is necessary to hang the design drawings on the hanging board for teaching. For convenience, usually transparent tape is used to fix the design drawings on the hanging board. Although the operation is simple, this method has many disadvanta...

Problems solved by technology

The teaching requirements in the field of mechanical drawing are also constantly improving. In teaching, not only should use textbooks, but also use various drawings as reference materials for teaching, so that students can observe and understand mechanical drawing more directly. However, due to lack of suitable The display stand brings inconvenience to teaching. It is necessary to hang the design drawings on the hanging board for teaching. For convenience, usually transparent tape is used to fix the design drawings on the hanging board. Although the operation is simple, this method has many disadvantages : The design drawing is inconvenient to move; it is inconvenient to tear off the transparent tape from the hanging board; the viscosity of the transparent tape will be greatly reduced after a period of use

There are following deficiencies in the above-mentioned patents: it is inconvenient to use and requires multiple people to operate, and the above-mentioned patents cannot solve such problems. Therefore, there is an urgent need for a display device for mechanical design that is convenient for placing drawings
