Abstract
The utility model discloses a kind of rule, device one chi, end at chi is provided with protractor, the protractor hemline is parallel with the axis of chi, the center of circle with protractor is a starting point, has the slit along the axis of chi, is provided with the radius length positioning sliding block in the slit, slit one side is from the center of circle of protractor, its upper surface mark has the length scale, and homonymy chi limit upper surface has also marked the length scale, and the center of circle of protractor is provided with center of circle pilot pin.The utility model is arranged at one with compasses, protractor, chi three, only need there be a such stationery to get final product the picture straight line, draws circle, do fan-shaped or measuring angle, use simple to operate, and saved cumbersome exchange of notes tool mapping, effectively the saves valuable time, simultaneously, carry more convenient, simpler and more direct certainly.
Description
Technical field:
The utility model relates to stationery, relates in particular to ruler, compasses, protractor.
Background technology:
Say from birth for junior-senior high school, all need use ruler, compasses, protractor during the doing mathematics operation, therefore this three samples stationery must be got all the ready in writing case, especially when examination, equally can not lack especially, otherwise just can not guarantee user demand.At present this three samples stationery is single individuality, but need work in coordination when being to use, for example when drawing a bowlder, the two pawl distances of at first handy dipstick metering compasses are justified with compasses then to determine the center of circle, and for example will make an angle, get and draw straight line with chi earlier, decide angle with protractor again, then with ruler another limit of drawing, to sum up, we can say that ruler, compasses, protractor are as discrete individuality, use both to bother, accuracy is also poor, and carries, takes care of also inconvenient.
Goal of the invention:
The technical problems to be solved in the utility model provides a kind of stationery with ruler, compasses, protractor function, and uses simply, conveniently, carries and take care of simpler and more direct.
The technical solution of the utility model is to realize like this, rule, device one chi, end at chi is provided with protractor, the protractor hemline is parallel with the axis of chi, the center of circle with protractor is a starting point, has along the axis of chi and meets the crack, and the width in this slit can migration be standard with nib therein, be provided with the radius length positioning sliding block in the slit, the center of circle of protractor is provided with center of circle pilot pin.
Beneficial effect:
The utility model is arranged at one with compasses, protractor, chi three, only need there be a such stationery to get final product the picture straight line, draws circle, do fan-shaped or measuring angle, use simple to operately, and saved the mapping of cumbersome exchange of notes tool, saves valuable time effectively, if on blackboard, justify with the utility model, fan-shaped etc. (teacher's use), not only simple to operate, and relatively easily.
When the most outstanding function of the utility model is each arc of picture, just can know the radius and the number of degrees of this arc.
Release of the present utility model because only need just can realize three effects that stationery had with a stationery, we can say carry the keeping more convenient, simpler and more direct.
Description of drawings:
Fig. 1 is the utility model schematic top plan view.
Fig. 2 is the utility model sliding block schematic diagram.
The specific embodiment:
As shown in Figure 1, the utility model is provided with protractor 2 at an end of chi 1, is starting point with the center of circle of protractor 2, has slit 3 along chi 1 axis, be provided with the radius length positioning sliding block in the slit 3, the circle centre position of protractor 2 is provided with center of circle pilot pin 4, and slit 3 one sides are from the center of circle of protractor 2, and its upper surface mark has the length scale, homonymy chi limit upper surface has also marked the length scale, a relative side chi end is a protractor 2, and is for the purpose of attractive in appearance, rounded in an end end of the chi that has protractor.
Still as shown in Figure 1, pilot pin 4 is embedded in the center of circle of protractor 2, and needle point only need expose needle point overleaf towards the back side of vertical view, as long as centering on paper (diagram is not provided) can guarantee to use the time.
As shown in Figure 1 and Figure 2, positioning sliding block is made up of sliding block 5, top shoe 6 and nut 7, sliding block 5 longitudinal center positions are provided with the screw rod that is complementary with nut 7, top shoe 6 longitudinal center positions are provided with screw, the screw rod of sliding block 5 passes from slit 3, pass the screw of top shoe 6 again, upper and lower slide block is fixed in the upper and lower surface in slit 3 with nut 7.Sliding block 5 all is wider than slit 3 with top shoe 6, the necessary consistency from top to bottom of sliding block 5 and top shoe 6 vertical limits with slit 3, the accuracy during with the assurance mapping.
The utility model is used for the fan-shaped operating process of picture, determine position, the center of circle earlier, with center of circle pilot pin 4 location, movement positioning sliding block, with positioning sliding block with respect to one side of protractor 2 this fan-shaped radius length of aliging, fastening nut 7 location are filled in slit 3 with nib from circle centre position, and suitable slit 3 setting-outs are to slide block, the radius that can draw is long, clockwise rotate chi 1 then around the center of circle to required radian place, again with pen along the slit 3 setting-outs promptly draw required fan-shaped to the center of circle.It is then simpler to draw circle with the utility model, equally, determine position, the center of circle earlier, with center of circle pilot pin 4 location, unclamp nut 7, and the running fix slide block, as this circular radius length place of aliging, above-mentioned limit with positioning sliding block, fastening nut 7 is filled in slit 3 with nib from the radius length place, clockwise rotates chi 1 around the center of circle and promptly draws circle or camber line.Make straight line or amount radian with the utility model, then with independent ruler, or protractor does not have what difference (giving unnecessary details in this one).
