Abstract
The utility model relates to a multifunctional plotter for students, which has the functions of a ruler, a protractor and compasses. The utility model is characterized in that a main scale has calibration tails for length, the lower end of the main scale is provided with the protractor; both sides of the main scale are provided with elliptical holes, hyperbola holes, big round holes and small round holes; the left side end of the main scale is provided with an extension rule which is vertical to the main scale, and the extension rule is placed in a groove and is in movable fit with the left side end of the main scale by screws; the top of the main scale is provided with a pencil lead, and the extension rule has calibration tails for length; the left lower end of the main scale is in movable fit with a screw, the end of the main scale is provided with a steel needle, and the right side of the main scale is provided with a rotary rod. The utility model has multiple functions of drawing an angle, a curve, a parallel line, a circle and an ellipse, and brings convenience for students in primary and middle schools.
Description
The utility model relates to a kind of culture and education and study and office appliance, is the drawing article that a kind of ruler, protractor, three kinds of functions of compasses are one specifically.
Drawing article is gone up in student's study at present or work ruler, protractor, compasses, but ruler can only be drawn straight line, protractor can only be with the tolerance angle, compasses are drawn circle merely, and outside the sharp needle point of the tiptoe of compasses is exposed to, to the easy prick skin of user, above-mentioned single ruler or protractor or the compasses triangle at some any angles that can not directly draw simultaneously also can't be with a kind of above-mentioned drawing article directly draw parallel lines, hyperbola or ellipse.
The purpose of this utility model provides a kind ofly can draw straight line, parallel lines and circle, can measure the usefulness of angle again, directly draw triangle, ellipse and the hyperbola at any angle simultaneously again, have the function of ruler, protractor, compasses, replace a kind of multifunctional student plotter of set square again.
For finishing the technical scheme that above-mentioned goal of the invention is taked: the graduation mark of long measure is established in the positive upper end at ruler, the graduation mark of long measure is established at center, main scale lower end respectively from inside to outside, and is that semicircle protractor and 0-180 degree groove and semi-circular hole are established in the center of circle with the center.Both sides at main scale are established elliptical aperture respectively, hyperbola hole and big hole, small sircle hole, the reverse side of main scale left end upper end is established the shrinkage-rule groove, shrinkage-rule can be placed in the groove, top face is established pencil-lead, make shrinkage-rule, main scale, pencil-lead fixed head do can fix again movingly by screw, the length graduation mark is established in the shrinkage-rule front.Lower end, main scale left side is provided with screw movingly, and is nested with spring, and screw end is established to perforation, in the draw point patchhole.Main scale right side swingle.
The utility model embodiment is described in detail in conjunction with the accompanying drawings.
Fig. 1 is the utility model structural representation.
According to shown in Figure 1, the utility model is established the graduation mark of long measure in the positive upper end of main scale 8, the graduation mark of long measure is established at the center of lower end respectively from inside to outside, and is that semicircle protractor 12 and 0-180 degree graduation mark and semi-circular hole 13 are established in the center of circle with the center.The both sides of main scale 8 are established elliptical aperture 6, hyperbola hole 7 and big hole 10, small sircle hole 9 respectively.The reverse side of main scale 8 left end upper end is established shrinkage-rule groove 1, shrinkage-rule 5 places in the groove, can move up and down, top face is established lead for retractable pencil fixed head 3 and pencil-lead 2, by screw 4 shrinkage-rule 5, main scale 8, fixed head 3 is done movingly or fixing, the length graduation mark is established in shrinkage-rule 5 fronts, lower end, main scale 8 left side is provided with screw 16 movingly, and is nested with spring 14, and screw end is established perforation, in draw point 15 inserted, swingle 11 was established on main scale 8 right sides.
Above-mentioned shrinkage-rule 5 moves that main to go out chi 8, two chis vertical mutually, can draw parallel lines and use.The draw point 15 of pencil-lead 2 makes pencil-lead 2 and draw point 15 turn to the left side of main scale 8 respectively by the rotation of screw 4 and screw 16, can make compasses by swingle 11 and use.
Can the draw a picture usefulness of angle, hyperbola, parallel lines, circle and ellipse of the utility model had both had the function of ruler, protractor, compasses, two functions that replace set square, and a multi-purpose instrument brings convenience for students in middle and primary schools.
