Rotation angulation ruler
Technical field
The utility model relates to a kind of chi, particularly a kind of rotation angulation ruler.
Background technology
As everyone knows, chi is an apparatus indispensable during people live, and the function of still existing chi is too single, can only play and measure the function of drawing straight line, and for angular surveying commonly used, and the angle drafting all can't be finished smoothly.
Chinese patent publication number CN201520139 U, open day on 07 07th, 2010, a kind of ruler that takes measurement of an angle is disclosed, comprise that two identical sizes are by the fixing transparent ruler of axle, be that the center of circle is provided with circle with the axle on ruler therein, circle is provided with scale, is provided with center line by axle on two rulers, and center line is parallel with the long limit of ruler.This utility model needs to draw, when taking measurement of an angle wherein a ruler pivot, the angle that forms between the center line can be read by the scale on the circle, but this utility model when measuring owing to exist ruler folding up and down, an easy appearance wherein ruler is moved, and is easy to generate than mistake especially during measurement.
Summary of the invention
It is too single that the purpose of this utility model is to solve in the prior art existing chi function, provides a kind of and can draw and measure a kind of rotation angulation ruler angle, simple in structure, easy to carry.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of rotation angulation ruler, comprise and be provided with the ruler of scale up and down, described rotation angulation ruler also includes the measurement piece, described measurement piece and ruler are hinged, described measurement piece is provided with the measurement scale, described ruler middle part is provided with through slot, described through slot is parallel with the long limit of described ruler, described measurement piece center is provided with aperture, described aperture is positioned on the extension line of described through slot, described measurement piece center to zero graduation is provided with the zeroing line, and two sides, described measurement piece middle part is provided with anti-skidding salient point.It is hinged to measure piece and ruler, measure piece and be provided with the measurement scale, the ruler middle part is provided with through slot, through slot is parallel with the long limit of described ruler, measure the piece center and be provided with aperture, described aperture is positioned on the extension line of described through slot, the user is set like this can measures angle easily, a limit of measured angle is overlapped with through slot, the aperture place of piece is measured in the summit alignment at angle, the measurement piece press...withes one's finger, rotating ruler overlaps with another limit at angle up to through slot, the reading that the pairing scale reading in rotating shaft of through slot is exactly the angle, if then can drawing a limit earlier, the drafting angle overlaps with through slot, the aperture place of piece is measured in the summit alignment at angle, the measurement piece press...withes one's finger, the user rotates the angle that ruler need be drawn the locating tab assembly piece to through slot, draw required angle by through slot then, can finish predetermined angle draws, measure piece center to zero graduation and be provided with the zeroing line, can make things convenient for the user to do zeroing in use and use, measure two sides, piece middle part and be provided with anti-skidding salient point, can when the user takes measurement of an angle, can not be moved, be difficult for producing than mistake.
As preferably, described measurement piece is that transparent rounded material is made.Measuring piece is made by circular transparent material and makes things convenient for the user to observe tested angle top whether it to be measured the center of piece, observe the one side whether the zeroing line of measuring piece aims at tested angle.
As preferably, ruler is made by stainless steel material.Ruler is made by stainless steel material can strengthen ruler intensity, is not easy breakage, has effectively prolonged service life.
The beneficial effects of the utility model are: by the measurement piece is set, made things convenient for the user that the angle angle is measured and drawn, it is simple to measure block structure simultaneously, easy to use, has reduced the possibility that measure error produces.

The specific embodiment
Below by specific embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
A kind of rotation angulation ruler (referring to accompanying drawing 1), comprise ruler 1, measure piece 2, through slot 3, aperture 4, zeroing line 5 and anti-skidding salient point 6, ruler is provided with scale in two long limits about in the of 1, ruler 1 is made for stainless steel material, ruler 1 is hinged with measurement piece 2, measuring piece 2 is made by circular transparent plastic, measure piece 2 circumference and be provided with angle index, measure piece 2 circle centre positions and be provided with aperture 4, measure piece circle centre position to zero graduation and be provided with zeroing line 5, measure square two sides, piece 2 middle parts and be provided with anti-skidding salient point 6(referring to accompanying drawing 2), ruler 1 middle part is provided with through slot 3, through slot 3 is parallel to the long limit of ruler 1, and through slot 3 is in same straight line with aperture 5.
The utility model in use, except line measurement commonly used, draw, the line that all needs will return to zero earlier aligns with through slot, finish zeroing, measure the angle angle as need, a limit of measured angle can be overlapped with through slot, the aperture place of piece is measured in the summit alignment at angle, and the measurement piece that press...withes one's finger rotates ruler and overlaps with another limit at angle up to through slot, the reading that the pairing scale reading in rotating shaft of through slot is exactly the angle, if the drafting angle then can be drawn a limit earlier and overlap with through slot, the aperture place of piece is measured in the summit alignment at angle, the measurement piece press...withes one's finger, the user rotates the angle that ruler need be drawn the locating tab assembly piece to through slot, draws required angle by through slot then, can finish predetermined angle angle and draw, use ruler to draw the length of side on required angle limit then as required, finish angle and draw.
Above-described embodiment is a kind of preferable scheme of the present utility model, is not that the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
