The utility model content
At the prior art above shortcomings, the purpose of this utility model provides a kind of easy to use, and it is arbitrarily angled to measure or draw, and angulation angle drawing device easy to process.
The purpose of this utility model is achieved in that the angulation angle drawing device, drawing the angle pointer by angulation angle drawing device main body and angulation forms, it is characterized in that, angulation angle drawing device main body is semicircle protractor, its middle part is provided with a semicircle orifice, the diameter inward flange of semicircle orifice and horizontal reference line parallel, the distance between diameter inward flange and the datum line are that angulation is drawn half of angle pointer width; The central point of one end of angulation angle drawing device pointer and angulation angle drawing device main body datum line flexibly connects, and the dial of the other end and angulation angle drawing device main body intersects; The vertically middle index line that is printed on of angulation angle drawing device pointer.
Further, the interior circular arc of described angulation angle drawing device main body is provided with up/descends and is 45 ° inclined-plane; To angulation angle drawing device pointer that should the inclined-plane be provided with down/on be reverse 45 ° ramp projections, and cooperate with the inclined-plane of circular arc in the angulation angle drawing device main body.
Also be provided with stopper slot on the described angulation angle drawing device main body, the width of stopper slot is corresponding with the ramp projections on the angulation angle drawing device pointer.
Compared to existing technology, the utlity model has following advantage:
1, this angulation angle drawing device refers to get final product angulation and draws the angle by the rotation pin, has characteristics easy to use, especially is fit to students in middle and primary schools and uses.
2, because the width of angulation angle drawing device pointer is carried out ingenious design, not only can guarantee the grazing of the arm of angle, and can measure or draw arbitrarily angled.
3, simple in structure, the angulation angle drawing device main body after assembling is finished is drawn the angle pointer to angulation and is defined scope of activities, and angulation is drawn the angle pointer can be movable in limited range, but can not break away from limited zone.
4, carry out interlocking because angulation angle drawing device main body and angulation are drawn the inclined-plane of angle pointer correspondence, not only effectively prevented coming off of angulation angle drawing device pointer, also have simple in structurely, make things convenient for machining characteristics.
Description of drawings:
Fig. 1 is the structural representation of the utility model angulation angle drawing device;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the schematic perspective view of the utility model angulation angle drawing device.
The specific embodiment
As shown in figures 1 and 3, the utility model angulation angle drawing device, drawing angle pointer 2 by angulation angle drawing device main body 1 and angulation forms, angulation angle drawing device main body 1 is semicircle protractor, be printed on 0 ° to 180 ° number of division on it, the middle part of angulation angle drawing device main body 1 is provided with a semicircle orifice 3, and the diameter inward flange 4 of semicircle orifice 3 is parallel with horizontal datum 5, and described horizontal datum 5 is 0 ° of graduation mark and 180 ° of straight lines that graduation mark is linked to be of angulation angle drawing device; Distance between diameter inward flange 4 and the datum line 5 is that angulation is drawn half of angle pointer 2 width.The central point 8 of one end of angulation angle drawing device pointer 2 and angulation angle drawing device main body 1 horizontal datum 5 flexibly connects, and the dial of the other end and angulation angle drawing device main body 1 intersects; The vertically middle index line 6 that is printed on of angulation angle drawing device pointer 2.
Referring to Fig. 2, the interior circular arc of angulation angle drawing device main body 1 is provided with up (or down) and is 45 ° inclined-plane; Angulation angle drawing device pointer 2 that should the inclined-plane is provided with down (or up) is 45 ° ramp projections, and cooperate with the inclined-plane of circular arc in the angulation angle drawing device main body 1.Carry out interlocking because angulation angle drawing device main body and angulation are drawn the inclined-plane of angle pointer correspondence, not only effectively prevented coming off of angulation angle drawing device pointer, also have simple in structurely, make things convenient for machining characteristics.
In addition, also be provided with stopper slot 7 on the angulation angle drawing device main body, the width of stopper slot 7 is corresponding with the ramp projections on the angulation angle drawing device pointer 2, and restriction angulation angle drawing device pointer 2 rotates in 0 ° to 180 ° scope.This angulation angle drawing device main body 1 and angulation are drawn angle pointer 2 and are made by transparent material.
According to the mathematical principle that corresponding angles equate, the diameter inward flange 4 that the user is intersected along the edge and the angulation angle drawing device main body 1 of angulation angle drawing device pointer 2 just can draw and pass the same angle of angle numerical value of (or sensing) with angulation angle drawing device pointer 2 center lines 6.The utility model is particularly suitable for students in middle and primary schools and uses.
Use the utility model to take measurement of an angle: angulation angle drawing device pointer 2 is rotating shaft with center of arc's point of angulation angle drawing device main body 1, rotate angulation angle drawing device pointer 2, and the index line of observing on the angulation angle drawing device pointer 2 passes the angle numerical value of (or sensing), can learn the angle of measurement fast and accurately.
The principle equal according to corresponding angles, perhaps the diameter inward flange 4 on the angulation angle drawing device main body 1 and angulation angle drawing device pointer 2 tops are overlapped with two limits at measured angle respectively, the index line of observing on the movable pointer 26 passes the angle numerical value of (or sensing), can learn the number of degrees at measured angle fast and accurately.
Use the utility model to draw angle: according to the principle that corresponding angles equate, along the edge and the diameter inward flange 4 of angulation angle drawing device pointer 2, the pointer index line that can draw passes the same angle of angle numerical value of (or sensing).
When angulation angle drawing device pointer 2 rotated to 0 degree or 180 degree, center line 6 overlapped with the horizontal datum 5 of angulation angle drawing device main body by center of arc's point in the middle of its pointer.Angulation angle drawing device pointer 2 rotates to 0 degree or 180 degree time, the edge of its angulation angle drawing device pointer 2 always have one with angulation angle drawing device main body 1 in the 4 parallel and coincidences of diameter inward flange.
