Abstract
The utility model provides a multifunctional accurate drawing ruler which comprises a protractor, an auxiliary ruler, an concave hole, a slide sleeve, a fixed nut, a main ruler and a rotating shaft, wherein, the protractor is hinged with the main ruler and the auxiliary ruler through the rotating shaft; the slide sleeve is arranged on the auxiliary ruler; the concave hole is arranged on the slide sleeve; and the side face of the slide sleeve is provided with the fixed nut. The multifunctional accurate drawing ruler simultaneously has the functions of a set square, a bow compass, a protractor and a ruler, and has the advantages of portability and high measuring and drawing accuracy. When the multifunctional accurate drawing ruler is used for drawing circles on paper, the beautiful appearance of drawing can not be influenced by damaged paper caused by a bow compass tip, and the multifunctional accurate drawing ruler is suitable for being used by teachers and students. Thereby, the multifunctional accurate drawing ruler has a high popularized use value.
Description
1, technical field
The utility model relates to a kind of schooling apparatus, specifically a kind of multifunctional accurate drawing ruler.
2, background technology
Need use a large amount of drawing instruments when middle school student learn geometry curriculum usually, the most frequently used have set square, compasses, protractor, a ruler etc., but existing drawing instrument function ratio is more single, has brought many inconvenience for teacher or carrying of student, and also inaccurate when taking measurement of an angle; Teacher also needs constantly to change drawing instrument in the process of teaching, the quality time on for this reason will the waste class.
Classmates are when using common compasses to draw on homework book, and the compasses point is very easy to paper is staved, and has influence on the attractive in appearance of operation.
3, summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of multifunctional accurate drawing ruler is provided, and this device also possesses functions such as set square, compasses, protractor, ruler simultaneously.
The technical solution of the utility model realizes in the following manner, its structure is made of protractor, secondary chi, shrinkage pool, sliding sleeve, hold-down nut, main scale and rotating shaft, protractor and main scale, secondary chi are hinged by rotating shaft, secondary chi is provided with sliding sleeve, sliding sleeve is provided with shrinkage pool, and the side of sliding sleeve is provided with hold-down nut.
Main scale and secondary chi are provided with scale.
The two ends of secondary chi are than middle part height, and the top of sliding sleeve and secondary chi two ends are contour.
The utility model has the advantages that:
(1), multifunctional accurate drawing ruler of the present utility model possessed the function of set square, compasses, protractor, ruler simultaneously, be easy to carry, and measure and the degree of accuracy of drawing very high, very be fit to teacher, the student uses.
(2), using the utility model the compasses point can not occur in the paper upper drawing circle staves paper and influences the situation attractive in appearance of drawing.

5, the specific embodiment
Below in conjunction with accompanying drawing 1-3 multifunctional accurate drawing ruler of the present utility model is done following detailed description the in detail.
As shown in Figure 1, its structure of multifunctional accurate drawing ruler of the present utility model is made of protractor 1, secondary chi 2, shrinkage pool 3, sliding sleeve 4, hold-down nut 5, main scale 6 and rotating shaft 7, protractor 1 and main scale 6, secondary chi 2 are hinged by rotating shaft 7, secondary chi 2 is provided with sliding sleeve 4, sliding sleeve 4 is provided with shrinkage pool 3, and the side of sliding sleeve 4 is provided with hold-down nut 5.
Main scale 6 and secondary chi 2 are provided with scale.
The two ends of secondary chi 2 are than middle part height, and the top of sliding sleeve 4 and secondary chi 2 two ends are contour.
At first regulate the radius of circle length of sliding sleeve 4 for requiring according to the scale value on the secondary chi 2 when using this device, then pen is inserted in the shrinkage pool 3, rotating a circle with the secondary chi 2 of pen drive to become circular arc; When taking measurement of an angle, rotation main scale 6 and secondary chi 2 can be read angle value accurately to two ray position throughput hornworks 1 of measured angle; Can be in the time of needs picture straight line with main scale 6 and the secondary chi 2 overlapping straight lines that can draw.
As shown in Figure 2, sliding sleeve 4 can be set to " L " shape; Also can be designed to hollow square tube shape, as shown in Figure 3.
Its processing and fabricating of multifunctional accurate drawing ruler of the present utility model is very simple and convenient, can process shown in the accompanying drawing to specifications.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art
