Description

Multifunction divider calipers

The utility model belongs to improved drawing instrument, is specifically related to a kind of used multi-functional divider calipers of imparting knowledge to students and learn.

Existing teaching and study generally include compasses, set square, protractor and ruler with drawing instrument, use, carry inconvenience, also need consume great deal of raw materials during manufacturing.

The purpose of this utility model is to provide a kind of drawing instrument of using, the function that can replace set square, protractor and ruler more, solves and uses, carries inconvenient shortcoming.

Task of the present utility model is finished as follows: it embodies with the form of general compasses, and setting-out leg and location leg are arranged respectively.The setting-out leg has the ruler of outer side edges lower edge, and upper end, setting-out inboard leg limit one semicircle protractor bores a through hole on the central point of protractor diameter line, and the lower end of setting-out leg is that picture material clamper is formed.The location leg is made up of the liner strip of bottom between grip block and the location ruler of lower edge, leg outer side limit and grip block and the ruler and the cushion angle of leg lower end, location.One folder mouth is formed at leg top, location, the folder mouth is gone up and is bored a through hole, by packing in the folder mouth of band protractor one lateral register leg top, setting-out leg upper end, the hole of protractor is corresponding with the hole on the folder mouth of leg top, location, and connect with a fastening bolt, setting-out leg and location leg also can merge into a single whole, and are easy to carry.The bottom surface of setting-out leg and lower edge, leg outer side limit, location ruler is convenient to drawing at grade, and setting-out leg hypomere inner side edge intersects on the center line of fastening bolt along long line along long line and location leg hypomere inner side edge.Leg top, location also has a reading window, the location scale mark of reading window is on the long line in edge of location leg hypomere inner side edge, simultaneously the reading window is corresponding with the scale face of protractor, and causing the location leg is the center can be observed protractor on the setting-out leg when rotating in 0 °-180 ° scale with the fastening bolt.When multi-functional divider calipers is done the set square use, at first partly finish triangle base line segment with the ruler on the setting-out leg of divider calipers, it is motionless to aim at the triangle hemline of being finished with the inner side edge of setting-out leg hypomere then, rotating divider calipers location leg makes on the reading window amount of alignment hornwork on leg top, location after the needed angle, along the inner side edge of the location leg hypomere hypotenuse line segment that draws, then arbitrarily with locating ruler on leg or the setting-out leg leg line segment that draws.When making protractor and use, setting-out leg hypomere inner side edge is aimed at the datum line rotational positioning leg of required angulation, make on the reading window amount of alignment hornwork of location on the leg after the measured or angle of drawing, draw a line segment along location leg hypomere inner side edge, the angle that the inboard pairing datum line of this line segment and setting-out leg hypomere forms is exactly an angle drawn or that measured.Can be if do the compasses use according to required picture diameter of a circle, adjust location leg and setting-out leg opening distance, cushion pin with leg lower end, location is the center of circle, and the distance of drawing between material folded picture material of clamper and the cushion pin with setting-out leg lower end is a radius, and rotation setting-out leg can arbitrarily be drawn circle.Location leg and setting-out leg become a ruler when expanding into 180 °, can draw long straight-line segment.

The utility model is used owing to a tool more, the function of its collection set square, protractor, ruler and compasses is an one, it both can make teacher's educational aid, can make student's learning tool again, overcome existing teaching, study drawing instrument carry and awkward shortcoming.Aspect starting material, only be equivalent to the shape of former compasses, thereby reduced production link, fallen at the end production cost, saved great deal of raw materials owing to compasses.
