Abstract
The utility model relates to a kind of teaching, schooling apparatus, particularly relates to a kind of full angle multi-function protractor.It comprises with full angle scale, clock scale, linear recess-based directrix index dial, angle mapping pointer, hour hands and minute hand, the mapping of above-mentioned angle pointer, hour hands and minute hand all by pinned connection on index dial, described angle mapping pointer, hour hands and minute hand scribble luminescent coating, are convenient to find in dark surrounds.The utility model complete independently process can being greater than the angle of 180 °, directly measuring and draw wide-angle and without the need to coordinating ruler or set square, also can possess understanding, learn and demonstrate the function of clock and watch, and be easy to find in dark surrounds, be easy to carry and take.
Description
Technical field
The utility model relates to a kind of teaching, schooling apparatus, particularly relates to a kind of full angle multi-function protractor.
Background technology
Protractor is common drawing tool, and its material mostly is plastics or irony, can draw desired angle as required.The angle gauging tool that current student commonly uses is protractor, and two conventional hornworks in use expose some weak point following: can only process the angle being not more than 180 °, is difficult to the angle of directly measuring and drawing angle wide-angle; Need when drawing the line of certain angle to coordinate ruler or set square to carry out, cannot complete independently; Function singleness, only for angle measurement with paint angle.
In sum, the unicity of protractor on using and the use on carrying and take care of be inconvenient to be the greatest problem applied at present, need design a kind of have dirigibility and comprehensive practical value, can the protractor of multi-use.
Summary of the invention
The technical problems to be solved in the utility model how to overcome the deficiencies in the prior art, a kind of angulation within the scope of full angle is provided, draws angle and once to complete and without the need to by other stationery, also can be used for learning clock and watch simultaneously, be easy to carry and the full angle multi-function protractor of taking.
The technical scheme that the utility model adopts for achieving the above object is: a kind of full angle multi-function protractor.It comprises index dial, angle mapping pointer, hour hands and minute hand, the mapping of above-mentioned angle pointer, hour hands and minute hand all by pinned connection on index dial, with the linear datum line groove of full angle scale, clock scale, strip length scale on described index dial, described angle mapping pointer can be used for observation angle with linear groove and draw lines.
Further: described angle mapping pointer, hour hands and minute hand scribble luminescent coating.
The utility model has the advantage of and disposable, independently can measure and draw the arbitrarily angled of 0 ° ~ 360 ° of scopes, without the need to the cooperation of other instruments; Except the mapping function of angle, also possess understanding, learn and demonstrate the function of clock and watch, and be easy in the dark find, be easy to carry and take.
Accompanying drawing explanation
Fig. 1 the utility model one-piece construction schematic diagram.
Embodiment
Embodiment 1:
A kind of full angle multi-function protractor, comprise index dial 1, angle mapping pointer 2, hour hands 3 and minute hand 4, above-mentioned angle mapping pointer 2, hour hands 3 and minute hand 4 are all connected on index dial 1 by bearing pin 5, with full angle scale 6, clock scale 7, linear datum line groove 8 on described index dial 1.Index dial 1, full angle scale 6 can be used to survey and draw pointer 2 observation angle with the described angle of band linear groove 10 and draw lines, also the linear datum line groove of strip length scale can be used to draw, measure straight line, and carry out the study of clock and watch identification by the clock scale 7 on hour hands, minute hand and index dial 1.
Embodiment 2:
Angle mapping pointer 2, hour hands 3 and minute hand 4 scribble luminescent coating, and remainder is identical with embodiment 1.
Above-described embodiment, just in order to technical conceive of the present utility model and feature are described, its objective is and is one of ordinary skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.The change of every equivalence done by the essence of the utility model content or modification, all should be encompassed in protection domain of the present utility model.
