Description

A class extension tool for engineering drawings

technical field

The utility model relates to the field of drawing utensils, in particular to an engineering drawing drawing tool.

Background technique

During college, architecture students have to practice the skills of hand-painted engineering drawings in the lower grades, and some renderings and design scheme drawings involve some rendering, so engineering drawings cannot be completed in one go, and tens of thousands of colors and renderings need to be completed After that, the ink line can be applied, which greatly increases the number of drawing sides of the students. The engineering drawings that were originally only drawn twice are drawn 2, 3 or even 4 or 5 times, which is cumbersome and boring. The traditional method of painting the engineering drawings with pencil dust on the back of the paper, and then engraving with a hard pen, greatly reduces the drawing efficiency, and the drawn drawings are not very clean, which also makes many architects Students stay up late to make drawings, which seriously damages the students' health.

Utility model content

The purpose of the utility model is to overcome the above-mentioned shortcomings of the prior art, and provide an engineering drawing extension tool that can improve the neatness of drawings and improve the efficiency of manual drawing.

In order to solve the above problems, the technical solution adopted by the utility model is: comprise a base plate, and a transparent plate installed on the base plate, the back side of the transparent plate is equipped with a light box for lighting; gap;

The front of the transparent board is provided with a first clip for fixing the paper, and the back of the transparent board is provided with a second clip for fixing the expanded paper.

The light box includes an aluminum plate for reflecting the light source and several LED light strips arranged parallel on the aluminum plate and facing the glass plate.

The length, width and height of the light box are 1000.00×800.00×50.00mm.

The bottom of the light box is also provided with a paper storage box.

The length, width and height of the paper storage box are 1000.00×800.00×20.00mm.

The first clip and the second clip are fixed by a fixed shaft.

The transparent plate is tempered glass.

Compared with the prior art, the utility model has the following beneficial effects: when drawing, the paper is fixed on the transparent plate with the first clip, and the paper to be expanded is fixed on the back of the glass plate with the second clip; when the light box is opened After the box, the light in the light box is directly reflected on the transparent plate, and the content of the expanded drawing is reflected on the expanded drawing. After using the utility model, the neatness of the drawings can be maintained during engineering drawing, and the efficiency of manual drawing can be greatly improved.

Further, since a paper storage box is provided for storing paper, it is convenient to take paper when drawing.

Description of drawings

Fig. 1 is a structural representation one of the utility model;

Fig. 2 is the structural representation two of the utility model;

Fig. 3 is the schematic diagram of the design of the internal light box of the map expander of the present utility model;

Among them, 1 is a transparent board, 2 is a light box, 3 is a first clip 4, an aluminum plate 5, an LED light strip 6, and a paper storage box.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Referring to Fig. 1 to Fig. 3, the utility model comprises base plate, and the transparent plate 1 that is installed on the base plate, is installed with the light box box 2 that is used for lighting on the back side of transparent plate 1; Gap: a paper storage box 6 with a length, width and height of 1000.00×800.00×20.00mm is arranged at the bottom of the light box 2, the length of the glass plate 1 is 1000.00mm, and the length, width and height of the light box 2 are 1000.00×800.00×50.00mm, And the light box box 2 includes an aluminum plate 4 for reflecting the light source and a plurality of LED light bars 5 arranged in parallel on the aluminum plate 4 facing the back of the glass plate 1 . The front of glass plate 1 is provided with the first clip 3 that is used for fixing paper, and the back side of glass plate 1 is provided with the second clip that cooperates with first clip 3 and is used for fixing the expanded paper, and this first clip and The second clip is secured by a fixed shaft.

Clips for fixing the paper are provided around the back and front of the glass plate 1, and a boundary dimension line is also provided on the glass plate 1. When drawing, the paper is placed along the boundary dimension line and fixed with the first clip 3 good. Place the expanded paper from the back of the glass plate 1 along the boundary dimension line, and also fix it with the second clip of the back glass plate. No matter from any direction, paper can be put in and fixed by the second clamp. The first clamp 3 and the second clamp are single-piece clamps that can rotate around a fixed axis. The paper is fixed between the glass plate 1 and the first clamp 3 . The paper to be rubbed is fed in from the short side of the back of the glass plate 1, attached to the back of the glass plate 1, and is also fixed with the first clip 3, a total of 4 sets of clips up and down, the clips on the back and front of the glass plate 1 are composed of one The fixed shafts are fixed, and there are four fixed shafts on the glass plate 1 in total.

When the switch is turned on, the light in the light box 2 is directly reflected on the glass plate 1, and the content of the drawing is reflected on the drawing.
