Abstract

A multifunctional protractor is composed of a protractor body and a ruler body. A fixing groove is formed in an inner circular ring at the right end of the protractor body, clamping grooves are formed in the two ends of the ruler body, and the clamping grooves are clamped on the inner circular ring of the protractor body to compose a structure capable of rotating along the inner ring of the protractor body. A row of holes are formed in the left end of the ruler body, a line drawing groove is formed in the right end of the ruler body, a radius positioning sliding block is mounted inside the line drawing groove, the radius positioning sliding block can be clamped on the fixing groove of the protractor body, and a sliding groove is formed in the position, corresponding to the line drawing groove, of the back portion of the ruler body. According to the multifunctional protractor, angles can be measured, simple straight lines can be drawn, circles with different radii can also be drawn, the functions of a ruler, a protractor and compasses are integrated, a surveying and mapping tool integrated with the functions of measuring the angles and sizes, drawing the straight lines and angle lines and drawing the circles is achieved, the structure is simple, and using is quick and convenient.

Description

Multi-function protractor

Technical field

The utility model relates to the surveying and mapping tool field, especially a kind ofly can be convenient for measuring angle, size, draws straight line, angle line, and draws the multi-function protractor that circle is integrated.

Background technology

At present, surveying and mapping tool commonly used has much on the market, wherein ruler, protractor, compasses are the most frequently used, function ratio was more single when these instruments used, and in the middle of daily learning life, finishing an operation often needs to use a plurality of surveying and mapping tools, if just use the surveying and mapping tool of these simple functions, always to people with serving unnecessary trouble.

The utility model content

The purpose of this utility model provides a kind of multi-function protractor, integrates ruler, protractor, calipers function, can take measurement of an angle, size, draws straight line, angle line, and the surveying and mapping tool of drawing circle, and is simple in structure, uses efficient and convenient.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of multi-function protractor, by the angulation body, the ruler body forms, have holddown groove on the annulus in the right-hand member of described angulation body, the two ends of ruler body are provided with draw-in groove, the draw-in groove position is stuck on the interior annulus of angulation body, forming one can be along the structure of ring rotation in the angulation body, the left end of ruler body has a round, right-hand member has the setting-out groove, the radius positioning sliding block is installed in the setting-out groove, the radius positioning sliding block may be stuck in the holddown groove place on the angulation body, and the place at the corresponding setting-out groove in ruler body back place has slide block slot.

As preferably, respectively be provided with scale on described angulation body and the ruler body.

As preferably, a round of described ruler body left end is that circular hole and diamond hole replace array structure.

As preferably, be provided with a graduation mark that aligns with angulation body zero graduation line in the middle of in described radius positioning sliding block the right screens.

As preferably, the left end of described radius positioning sliding block has semicircle orifice, and the centre is provided with setscrew nut.

The beneficial effects of the utility model are: a kind of multi-function protractor, not only can take measurement of an angle and draw simple straight line, and because the ruler body can along ring rotation in the angulation body, utilize hole or the slide block established on the ruler body, by rotation ruler body, also can draw the circle of different radii, integrate ruler, protractor, calipers function, be have take measurement of an angle, size, draw straight line, angle line, and draw the surveying and mapping tool that the circle function is integrated, and simple in structure, use efficient and convenient.

The specific embodiment

As shown in Figure 1, a kind of multi-function protractor is comprised of angulation body (1), ruler body (2), and the left end of ruler body (2) has a round, right-hand member has setting-out groove (5), and radius positioning sliding block (3) is installed in the setting-out groove (5).

As shown in Figure 2, have holddown groove (4) on the annulus in the right-hand member of angulation body (1), the outer shroud of angulation body (1) and interior ring limit are individual to indicate scale strip, and the centre of scale strip indicates the whole ten angle index numbers of 0-350 degree.

As shown in Figure 3, a round of ruler body left end is that circular hole and diamond hole replace array structure, and wherein the distance of adjacent circular holes and diamond hole is 5mm, and the ruler body also indicates scale in two ends up and down.

See Fig. 4, the two ends of ruler body (2) are provided with draw-in groove (10), draw-in groove (10) position is stuck on the interior annulus of angulation body (1), forming one can be along the structure of ring rotation in the angulation body (1), and the place that the corresponding setting-out groove in ruler body (2) back (5) is located has slide block slot (8).

As shown in Figure 1, when radius positioning sliding block (3) slided into the right-hand member of ruler body, the holddown groove (4) that may be stuck on the angulation body (1) was located to fix.

As shown in Figure 5, the left end of radius positioning sliding block (3) has semicircle orifice (9), and the centre is provided with setscrew nut (11).
