Embodiment Construction

[0033] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] see Figure 1 to Figure 4 : the drawing board of the present invention comprises: 30 ° of right-angled triangular plate assembly, 45 ° of right-angled isosceles triangular plate assembly and ruler plate. The details are as follows:

[0035] Such as figure 1 As shown, the 30° right-angle triangular plate assembly includes a rectangular plate A, referenced by 1, and two 30° right-angle triangular plates 2 with exactly the same shape and size. Such as figure 2 As shown, the area of ​​the rectangular plate A is equal to the area when two 30° right-angled triangular plates are spliced ​​together, that is, the long side of the rectangular plate A and the long right-angled side of the 30° right-angled triangular pla...

Abstract

The invention relates to drawing stationery, in particular to a combined type drawing board. In order to solve the problems that an existing drawing board is prone to injuring people due to a pointed part and not convenient to carry, the combined type drawing board which is simple in structure, convenient to use and easy in combination is provided. A pointed angle of a set square can be folded, the drawing board is convenient to carry, and the possibility of injuring people is reduced. According to the technical scheme, the combined type drawing board comprises a 30-degree right-angled set square assembly, a 45-degree right-angled isosceles set square assembly and a ruler plate. When used, the 30-degree right-angled set square assembly and the 45-degree right-angled isosceles set square assembly can be combined to be large-size set squares in the corresponding shapes correspondingly; and when not used, the two assemblies can be combined to be two rectangular plates correspondingly. The combined type drawing board has the beneficial effects that while the conventional functions are maintained, the combined type drawing board is simple in structure, convenient to use, carry and manage, not prone to losing, high in drawing efficiency and attractive in appearance, and drawing operations are facilitated greatly.

Description

technical field [0001] The invention relates to a drawing stationery, in particular to a combined drawing board. Background technique [0002] In daily study and work, drawing boards are widely used, and these drawing stationery mainly include ruler, 45 ° right angle isosceles triangle, 30 ° (or 60 °) right angle triangle and protractor. However, in the process of using the triangular plate, its tip is easily worn and broken, which is inconvenient to carry, especially the tip is easy to hurt people. Contents of the invention [0003] (1) Technical problems to be solved [0004] The object of the present invention is to provide a drawing tablet with simple structure, convenient use and easy assembly in view of the above-mentioned deficiencies in the prior art. It can fold the sharp corners of the triangular board, which is easy to carry and reduces the possibility of injury. [0005] (2) Technical solution [0006] In order to solve the above technical problems, the inv...
