Abstract
A foldable angle ruler comprises two rulers hinged to each other. Upper and lower edges of the rulers are provided with scales. An angle gauge is arranged at the hinged joint of the two rulers. Datum point of the angle gauge and the hinged joint of the two rulers coincide. The foldable angle ruler is simple in structure. As the angle gauge is arranged at the hinged joint of the two rulers, not only straight lines but angles can be measured and drawn. Measurement and drawing of the straight lines and angles are completed by one ruler, thereby bringing convenience to users. In addition, the foldable angle ruler is portable, and waste of resources is reduced.
Description
Technical field
The utility model 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, can only play the function of measuring straight line and drawing straight line, for taking measurement of an angle and drawing angle, just can not rely on ruler to realize, if need to measure and draw angle, just need to separately be with an angle square, the easy like this waste that causes resource, and carry also very inconvenient.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, proposes a kind ofly both can measure and draw straight line, can measure and draw again the folding angle gauging straight scale of angle.
The technical problems to be solved in the utility model is to realize by the following technical programs, a kind of folding angle gauging straight scale, be characterized in: comprise two rulers that are hinged, the upper lower limb of described ruler is equipped with scale, two ruler hinged places, be provided with a protractor, the datum mark of protractor overlaps with the pin joint of two rulers.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, and described ruler and protractor are transparent plastic or stainless steel material is made.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, and the scale of described protractor is 0 °～360 °.
Compared with prior art, the utility model is simple in structure, by being arranged on the protractor of two ruler hinged places, both can realize the measurement of straight line and drafting, also realized to the measurement of angle and and draw; Realized and utilized a ruler to complete the measurement of straight line and angle and drafting, facilitated user be applicable to carry, meanwhile, also reduced the waste of resource.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A folding angle gauging straight scale, comprises two rulers 1 that are hinged, and the upper lower limb of described ruler 1 is equipped with scale, two ruler 1 hinged places, is provided with a protractor 2, and 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 that is arranged on ruler 1 hinged place just can be measured 360 ° with interior any angle.
On described ruler 1, lower limb all has scale, so all can measure and draw straight line up and down, if after any ruler is fixing, another ruler 1 can rotate arbitrarily by jointed shaft, and the angle of rotation can be measured by being arranged on the protractor 2 of hinged place.Another is convenient is opened into 180 ° by jointed shaft by two rulers 1 and just can lengthens the measurement of straight line and drafting when needs are measured and draw straight line, and while not using ruler, utilizes jointed shaft by 1 coincidence of two rulers, facilitates user to carry.
