Abstract
The utility model relates to a combined drawing board and belongs to a stationery. Mainly, the problem of inconvenience in using, which is generated when various tools are separately placed in the drawing process, is solved. The combined drawing board comprises a drawing board body and is characterized in that the drawing board body consists of a ruler, a right-angle set square, an equilateral set square and a protractor; and one corners of the ruler, the right-angle set square, the equilateral set square and the protractor are all respectively provided with a through hole and are connected through a pin shaft. The combined drawing board has simple structure and is convenient to use. All the tools are combined, so that the tools can be effectively prevented from being lost and the problems of low drawing efficiency and low quality, which are caused by incompleteness of the tools, can be effectively reduced and avoided.
Description
Technical field
The utility model relates to a kind of stationery, specifically is a kind of combination drawing board.
Background technology
In daily study, work and the life; a lot of people run into manual situation of drawing through regular meeting, for guaranteeing shape, dimensional standard, standard, and need be by instruments such as ruler, set square, protractors; but in practical operation; various tool is deposited separately, easily loses and inconvenience is carried, and attends to one thing and lose sight of another through regular meeting during use; be difficult to guarantee that all kinds of workers, amount, utensil are complete; so cause drawing efficiency very low, quality can't satisfy people's needs, has a strong impact on normal working and learning.
The utility model content
The purpose of this utility model is to provide a kind of combination drawing board, and this drawing board combines ruler with instruments such as set square and protractors, can carry out drawing work quickly and accurately.
The technical scheme in the invention for solving the technical problem is: a kind of combination drawing board, comprise the drawing board body, it is characterized in that, described drawing board body is made of ruler, right angle triangle, equilateral triangle plate and protractor, is equipped with through hole and is connected by bearing pin in the through hole at described ruler, right angle triangle, equilateral triangle plate and protractor one jiao.
The beneficial effects of the utility model are: various drawing rules commonly used are combined, simple in structure, easy to use, each instrument is interrelated can effectively to prevent loss, and can effectively reduce and avoid the low and ropy problem of the incomplete drawing efficiency that causes of instrument.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 ruler, 2 right angle triangles, 3 equilateral triangle plates, 4 protractors, 5 bearing pins.
The specific embodiment
As shown in Figure 1.A kind of combination drawing board, comprise the drawing board body, described drawing board body is made of ruler 1, right angle triangle 2, equilateral triangle plate 3 and protractor 4, is equipped with through hole and is connected by bearing pin 5 in the through hole at described ruler 1, right angle triangle 2, equilateral triangle plate 3 and protractor 4 one jiao.
During use, each tool location all can freely rotate around bearing pin 5, and people screw out the instrument that need to use and draw or measure and get final product.The utility model is simple in structure, and is easy to use, and each instrument is interrelated can effectively to prevent loss, and can effectively reduce and avoid the low and ropy problem of the incomplete drawing efficiency that causes of instrument.
