Abstract
The invention relates to a multifunctional drawing tool which comprises a ruler 1 and a ruler 2. One end of the ruler 1 is connected with one end of the ruler 2 by a magnetic central shaft 7; a slide block 4 is arranged on the ruler 1; one side of the slide block 4 is provided with a taper hole 12 used for holding a chalk; a slide block 5 is arranged on the ruler 2; one side of the slide block 5 is provided with a taper hole 11 used for holding a chalk; the magnetic central shaft 7 is provided with a dial 3; and the lowest part of the magnetic central shaft 7 is provided with a sucking disc 8. When the multifunctional drawing tool is used, a chalk is firstly cut into a taper shape or a long-flat shape by the end of the ruler and put into the taper hole of the slide block to be clamped fixedly, then the sucking disc is fixedly adsorbed on a blackboard for fixation, and the drawing tool can draw straight lines in any angles, circular arcs in any angle, radius, ellipses, concentric circles, and the like and has the advantages of convenience and accuracy.
Description
Technical field
The present invention relates to a kind of teaching multifunctional drawing tool.
Background technology
Traditional teaching drawing instrument adopts wooden compasses, 45 ° of right angle triangles and 60 ° of right angle triangles and protractor etc.
Traditional teaching aid is mapped for the teacher on blackboard and is brought inconvenience, for example: on blackboard during draw circles, because traditional compasses centralized positioning pin is a steel nail, the conference damage blackboard of exerting oneself, the too small then center of exerting oneself wanders off easily, teacher's need one hand steered steady steel nail pin rotates compasses on the other hand and draws, the very inconvenient and certain skill of needs.When set square was drawn, the teacher need be fixed on the other hand and hold up surely, and another hand is drawn straight line with chalk, and ruler is a deflection slightly, and the straight line of drafting also tilts immediately.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of multifunctional drawing tool, the function of integrated compasses and ruler can be drawn arbitrarily angled straight line, arbitrarily angled circular arc, ellipse, concentric circles, has conveniently, characteristic of accurate.
To achieve these goals, the technical solution used in the present invention is: a kind of multifunctional drawing tool, include ruler 1 and ruler 2 that an end links to each other by magnetic central shaft 7, ruler 1 is provided with slide block 4, one side of slide block 4 is provided with the bellmouth 12 that the dress chalk is used, and ruler 2 is provided with slide block 5, and a side of slide block 5 is provided with the bellmouth 11 that the dress chalk is used, also be provided with dial 3 on the magnetic central shaft 7, be provided with sucker 8 at the foot of magnetic central shaft 7.
Also be provided with screw 6 on described slide block 4, the slide block 5.
Be carved with master scale on described ruler 1, the ruler 2.
The material of described ruler 1, ruler 2 is a transparent organic glass.
The end of described ruler 1, ruler 2 has the trapezoidal hole 10 of the conical threaded holes 9 and the horizontal direction of vertical direction, is used for grinding chalk end.
The present invention is owing to adopt magnetic central shaft 7 that ruler 1, ruler 2 are connected, so ruler 1, ruler 2 all can rotate around magnetic central shaft 7, is used for draw circles or circular arc; Because the foot at magnetic central shaft 7 is provided with sucker 8, so the present invention can be adsorbed on the blackboard; Because magnetic central shaft 7 is provided with dial 3, so can draw round at any angle; Owing to be carved with master scale on ruler 1, the ruler 2, so slide block 4,5 can slide, draw the straight line of setting on ruler 1, ruler 2, have convenience, characteristic of accurate.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is explosive effect figure of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present invention and operation principle are described in further detail.
Referring to Fig. 1,2, a kind of multifunctional drawing tool, include ruler 1 and ruler 2 that an end is connected by magnetic central shaft 7, ruler 1 is provided with slide block 4, one side of slide block 4 is provided with taper chalk hole 12, and ruler 2 is provided with slide block 5, and a side of slide block 5 is provided with taper chalk hole 11, also be provided with dial 3 on the magnetic central shaft 7, be provided with sucker 8 at the foot of magnetic central shaft 7.Also be provided with screw 6 on described slide block 4, the slide block 5.Be carved with master scale on described ruler 1, the ruler 2.The material of described ruler 1, ruler 2 is a transparent organic glass.Described ruler 1, ruler 2 ends have the trapezoidal hole 10 of the conical threaded holes 9 and the horizontal direction of vertical direction, can be according to teacher's the tapered or prolate shape of drawing custom grinding chalk.During grinding, chalk is placed conical threaded holes 9 rotations, can claim taper shape the grinding of chalk end; With the trapezoidal hole 10 back and forth grinding of chalk, the chalk end can be ground to prolate shape, so that draw uniform lines along horizontal direction.
As shown in Figure 2, behind the screw 6 that unclamps on slide block 4, the slide block 5, slide block 4, slide block 5 can slide along ruler 1, ruler 2 respectively; After tightening screw 6, slide block 4, slide block 5 are separately fixed on ruler 1, the ruler 2.The elongated portion of magnetic central shaft 7 passes the hole of ruler 1 and ruler 2 one ends and the centre bore of dial 3 matches with the hole of an end of sucker 8, and an end, dial 3 and the sucker 8 of chi 1 and ruler 2 is fixed together.
Operation principle of the present invention is:
When utilizing the present invention to draw, earlier chalk is ground to taper or prolate shape in the ruler end and puts into the bellmouth of slide block and clip admittedly, again sucker 8 is drawn onto on the blackboard fixedly, can draw straight line, circular arc, and oval.Because central shaft 7 has magnetic,, also can directly be adsorbed on the blackboard with the nose circle of central shaft 7 if blackboard can adsorb magnetic medium.
When drawing straight line, according to the Length Indication on indication of the angle on the dial 3 and the ruler, ruler is ajusted direction, moving slider is to assigned scale, and the straight line of specified angle, designated length can draw.
When drawing circular arc, determine arc radius earlier, slide block 4 is moved to assigned scale along ruler, tighten fixedly slide block of screw 6, rotate ruler, the circle or the circular arc of can draw appointment radius, specified angle.
When drawing ellipse, earlier two rulers are placed level, guarantee that two slide blocks and ruler center are on same linear position.Two slide blocks are moved to transverse two-end-point position respectively, look for the single line rope, two ends tie up to respectively on the shank of screw of two slide blocks, the tensioning cotton rope.Then, to center position simultaneously moving slider fix two slide blocks to distance to a declared goal, this moment cord relaxed, with the lax cotton rope of chalk tensioning on one side, one side setting-out, the lines of drawing out are ellipse.
When drawing concentric circles, slide block 4,5 is moved to different scale lengths along ruler 1,2 respectively, tighten screw and fix, rotate ruler 1,2 simultaneously, can draw two concentric circles.
In the accompanying drawing:
The 1-ruler; The 2-ruler; The 3-dial; The 4-slide block; The 5-slide block; The 6-screw; 7-magnetic The magnetic central shaft; The 8-sucker; The 9-conical screw hole; The horizontal trapezoidal hole of 10-; The 11-chalk is installed The hole; 12-chalk installing hole.
