Description
Technical field:
The utility model relates to drawing tool for teaching technical field, especially relates to a kind of multi-functional ruler-compasses.
Background technology:
At present, traditional ruler and calipers function single, size is larger, carries inconvenience, and compasses center of circle part when drawing adopts nail as fixture, uses extremely unstable.Teacher holds chi on the other hand on blackboard, holds chalk on the other hand and draws, easily skid, use and waste time and energy, fatiguability, and draw inaccuracy.
Summary of the invention:
The utility model be for prior art defect and a kind of multi-functional ruler-compasses is provided, thus efficiently solve the problems of the prior art.
The utility model solves the scheme that its technical problem adopts: described multi-functional ruler-compasses, be characterized in comprising two identical upper brackets of structure, two upper bracket upper ends are arranged on contiguous block by pin, two upper bracket lower ends are connected with two lower carriages by hinge, one of them lower carriage lower end is provided with rubber fulcrum, is also provided with circular sliding slopes device and positioning rule between two upper brackets.
Launching lateral surface after described upper bracket is connected with lower carriage is horizontal plane, is provided with scale and uses for ruler line.
Described circular sliding slopes device is provided with arc chute, the upper bracket of corresponding arc chute is provided with the first screw, the arc angle that circular sliding slopes device is arranged is 0 ~ 180 degree, realizes by the first screw in the arc chute on fixing circular sliding slopes device the Angle ambiguity portraying circular arc.
Described positioning rule one end is connected with side upper bracket, the positioning rule other end is provided with straight runner, the opposite side upper bracket of corresponding straight runner is provided with the second screw, described multi-functional ruler-compasses expands into isosceles triangle, positioning rule is arranged on centre position, is realized the size Control of picture circle by positioning rule.
The utility model is by technique scheme, and there is following effect: described multi-functional ruler-compasses, ruler, protractor, compasses three are combined into one by it, realize precisely drawing circle, draw straight line, the function of Quick Measurement and picture angle, make teacher save time in classroom and improve classroom efficiency.Made by ruler and can fold, small volume and less weight after folding, takies little room, facilitates teacher to carry.

Detailed description of the invention
Below in conjunction with accompanying drawing shownschematically most preferred embodiment be described in further detail:
As shown in Figures 1 to 4, described multi-functional ruler-compasses, be characterized in comprising two identical upper brackets 1 of structure, two upper bracket 1 upper ends are arranged on contiguous block 7 by pin 8, two upper bracket 1 lower ends are connected with two lower carriages 5 by hinge 6, one of them lower carriage 5 lower end is provided with between rubber fulcrum 4, two upper brackets 1 and is also provided with circular sliding slopes device 2 and positioning rule 3.
Launching lateral surface after described upper bracket 1 is connected with lower carriage 5 is horizontal plane, is provided with scale and uses for ruler line.
Described circular sliding slopes device 2 is provided with arc chute 9, the upper bracket 1 of corresponding arc chute 9 is provided with the first screw 10, the arc angle that circular sliding slopes device 2 is arranged is 0 ~ 180 degree, realizes by the first screw 10 in the arc chute 9 on fixing circular sliding slopes device 2 Angle ambiguity portraying circular arc.
Described positioning rule 3 one end is connected with side upper bracket, positioning rule 3 other end is provided with straight runner 11, the opposite side upper bracket of corresponding straight runner 11 is provided with the second screw 12, described multi-functional ruler-compasses expands into isosceles triangle, positioning rule 2 is arranged on centre position, is realized the size Control of picture circle by positioning rule 2.
Above-mentioned example is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and implement according to this; can not with this protection domain of the present utility model; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
