Abstract

A foldable ruler with an angle measuring function comprises to ruler bodies which are hinged to each other. The upper and lower edges of each ruler body is provided with scale marks. A protractor is disposed at the hinge of the two ruler bodies. The reference point of the protractor coincides with the hinge point of the two ruler bodies. The foldable ruler has the advantages that the ruler is simple in structure and convenient to carry, straight line measuring and drawing are achieved by the ruler bodies, angle measuring and drawing are achieved by the protractor, , and resource waste is reduced.

Description

Folding angle gauging straight scale
Technical field
The present invention relates to a kind of survey tool, particularly a kind of folding angle gauging straight scale.
Background technology
At present, ruler is student's indispensable survey tool in the study, but existing ruler purposes is more single, the function measured straight line and draw straight line can only be played, ruler just can not be relied on to achieve for taking measurement of an angle and drawing angle, if need to measure and draw angle, just need another band one angle square, the easy like this waste causing resource, and carry also very inconvenient.
Summary of the invention
The technical problem to be solved in the present invention is for the deficiencies in the prior art, proposes one and both can measure and draw straight line, can measure and draw again the folding angle gauging straight scale of angle.
The technical problem to be solved in the present invention is realize by the following technical programs, a kind of folding angle gauging straight scale, be characterized in: comprise two rulers be hinged, the lower edges of described ruler is equipped with scale, be provided with a protractor two ruler hinged places, the datum mark of protractor overlaps with the pin joint of two rulers.
The technical problem to be solved in the present invention can also be come to realize further by the following technical programs, and described ruler and protractor are transparent plastic or stainless steel material is made.
The technical problem to be solved in the present invention can also be come to realize further by the following technical programs, and the scale of described protractor is 0 ° ~ 360 °.
Compared with prior art, structure of the present invention is simple, by being arranged on the protractor of two ruler hinged places, both can realize the measurement to straight line and drafting, also achieve to the measurement of angle and and draw; Achieve and utilize a ruler to complete measurement to straight line and angle and drafting, facilitate user be applicable to carry, meanwhile, decrease the waste of resource.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
A kind of folding angle gauging straight scale, comprise two rulers 1 be hinged, the lower edges of described ruler 1 is equipped with scale, and be provided with a protractor 2 two ruler 1 hinged places, the datum mark of protractor 2 overlaps with the pin joint of two rulers 1.
Described ruler 1 and protractor 2 is transparent plastic or stainless steel material is made; The scale of described protractor 2 is 0 ° ~ 360 °.Utilize transparent plastic conveniently to observe and record, and utilize stainless steel material can strengthen the intensity of ruler, make ruler not easy to wear, extend the service life of ruler.Because ruler 1 is hinged, and the protractor 2 being arranged on ruler 1 hinged place just can measure any angle within 360 °.
Described ruler 1 lower edges all has scale, so all can measure up and down and draw straight line, if after any ruler is fixing, another ruler 1 rotates arbitrarily by jointed shaft, and the angle rotated can be measured by the protractor 2 being arranged on hinged place.Another convenient needs measure and drafting straight line time, two rulers 1 is opened into 180 ° by jointed shaft and just can lengthens measurement to straight line and drafting, and when not using ruler, then utilize jointed shaft to be overlapped by two rulers 1, person easy to use carries.
