Abstract

The utility model relates to a novel common palette and a T-shaped square and the structure is that a groove is added on the palette and a heave is added on the head of the T-shaped square based on a common palette; the palette and the T-shaped square are combined more tightly by the matching of the groove and the heave, thus solving the problem that the T-shaped square is easy to deflect when in drawing; meanwhile, the groove and the heave only need buckling when in use, leading to more convenient and faster drawing; the T-shaped square does not lean when moved horizontally, thus leading to more precise drawing.

Description

Drawing board and T-square

Technical field

The utility model relates to a kind of drawing board and T-square, belongs to a kind of of drawing instrument.

Background technology

Although computer graphics obtains application more and more widely, manual drawing is still indispensable, and still occupies very big proportion.The manual very big shortcoming of existence of drawing is exactly that inconvenience and accuracy are low, the illustrator is usually because touch when causing ruling inaccurate between drawing board and the T-square, such as the excessive T-square that causes tilts because line the time is exerted oneself, in a word T-square vertically the drawing board placement cause drawing effect very poor.

Summary of the invention

At the deficiency of above-mentioned existing common drawing board and T-square, the utility model provide a kind of simple in structure, mapping operation is more convenient, can improve the drawing board and the T-square of the drawing degree of accuracy.

The utility model is achieved through the following technical solutions: novel drawing board and T-square, be on the basis of common drawing board, on drawing board, increased groove, head on T-square has increased projection, and the basic size of the width of bossing and groove part and height equates that groove and bossing all are rectangular-shaped.The position of the groove on the drawing board is on two adjacent long and narrow inoperative planes, the bossing of T-square is in the lower part of T-square head, plane on the distance of T-square blade bottom surface and the drawing board upper groove, plane equates to the distance of drawing board working face on the projection, thus make the two in conjunction with the time T-square blade bottom surface tightly touch the drawing board working face just.

When the utility model is used, the bossing of T-square and the groove of drawing board are matched, like this T-square just and drawing board be adjacent to, because exerting oneself excessive, line cause T-square to tilt with regard to not occurring during drawing, do not need during use to align, only need the groove projection is passable once detaining, make the work more convenient and quicker that becomes.Because groove has certain degree of depth, when the translation T-square, just the tilt phenomenon of T-square can not occur, thereby make drawing more accurate.

Description of drawings

Fig. 1 is drawing board and T-square overall profile figure;

Fig. 2 is an A part drawing board groove part schematic diagram among Fig. 1;

Fig. 3 is an A part T-square bossing schematic diagram among Fig. 1;

Among the figure, 1. drawing board, 2. T-square, 3. projection, 4. groove.

The specific embodiment

Embodiment: as Fig. 1, Fig. 2 and shown in Figure 3, it is fluted 4 that drawing board 1 side is provided with, T-square 2 heads be provided with drawing board 1 on groove 4 corresponding protruding 3.On the side of drawing board 1, fluted 4 on two wherein adjacent sides, bottom land is smooth plane.

During drawing, the T-square bossing is buckled in the drawing board groove part gets final product, can mobile T-square, T-square bossing 3 translation in the groove of drawing board can not produce inclination, and is more accurate thereby the drawing result becomes.

Claims

1, drawing board and T-square comprise drawing board and T-square, it is characterized in that: the drawing board side is provided with fluted, the T-square head be provided with drawing board on the corresponding projection of groove.

2, drawing board according to claim 1 and T-square is characterized in that: on the side of described drawing board, fluted on two wherein adjacent sides, bottom land is smooth plane.
