Abstract
A multifunctional set square is characterized in that: the base plane of set-square (1) is equipped with spout (2) and arc spout (3), be equipped with two slide bars (4, 5) in spout (2), the one end of slide bar (4, 5) is fixed in the slide through knob screw (6) respectively, the other end passes through swivel screw (6) cross connection and fixes in arc spout (3), respectively be equipped with hollow slide (7) on slide bar (4, 5), the limit is equipped with angulation scale (8) in arc spout (3), be equipped with angulation centre of a circle (9) in spout (2). The utility model discloses combine protractor and set-square as an organic whole to rationally increased the circular arc of drawing appointed angle and triangle-shaped's function, made things convenient for more measure and drawing, convenient to use.
Description
Technical field
The utility model relates to drawing appliance, particularly a kind of multifunctional triangle.
Background technology
Set square is some functions that indispensable in the drawing appliance, common set square only has drawing, measurement length.Also have some multifunctional triangle practicality neither be very strong, many all be to have increased to take measurement of an angle and draw circular function.When the circular arc of drawing specified angle and triangle, must the good angle of handy angulation tolerance draw again, so just cumbersome.
Summary of the invention
The purpose of this utility model provides a kind ofly can do protractor, also so that draw the triangle of any angle or the multifunctional triangle of circular arc.
The feature of described multifunctional triangle is: the basal plane of set square is provided with chute and arc chute, in chute, be provided with two slide bars, one end of slide bar is fixed in the slideway by knob bolts respectively, the other end is by the rotary screw interconnection and be fixed in the arc chute, respectively be provided with hollow slideway on the slide bar, the arc chute inner edge is provided with angle measuring calibration, is provided with the angulation center of circle in chute.
The utility model is combined as a whole protractor and set square, and has rationally increased the circular arc and the leg-of-mutton function of drawing specified angle, is more convenient for measuring and drawing, and is easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-set square, 2-chute, 3-arc chute, 4, the 5-slide bar, 6-knob bolts, the hollow slideway of 7-, 8-angle measuring calibration, the 9-angulation center of circle.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.Among Fig. 1, the basal plane of set square 1 is provided with chute 2 and arc chute 3, in chute 2, be provided with two slide bars 4,5, one end of slide bar 4,5 is fixed in the slideway by knob bolts 6 respectively, the other end is by rotary screw 6 interconnections and be fixed in the arc chute 3, respectively be provided with hollow slideway 7 on the slide bar 4,5, arc chute 3 inner edges are provided with angle measuring calibration 8, are provided with the angulation center of circle 9 in chute 2.
The rotary screw 6 of fixed slip bar 3,4 is unscrewed, slide bar 4,5 just can slide along chute 2 and arc chute 3, inner edge at arc chute 3 is provided with angle measuring calibration 8, slide bar 4,5 is slided into the angle of finger again with screw-driving, just the respective angles triangle can be drawn, also triangle at any angle can be drawn.In chute 2, be provided with the angulation center of circle 9, taking measurement of an angle and drawing circular arc, can use when fan-shaped.Draw circular arc and when fan-shaped, an end of a slide bar wherein is fixed on the position in the angulation center of circle, the other end slides in arc chute 3, slides into just fixing graphing of respective angles.The function of binding capacity hornwork and set square gets final product the angle of length measured, curve, also can draw multiple figure, and one-object-many-purposes is practical and convenient.
