Above-mentioned disclosed front two drawing tools all relate to be integrated existing independently drawing tools, the 3rd and the 4th drawing tools relate to existing freestanding drawing tools are improved, and they remove to improve the overall performance of existing drawing tools from different angles.But these devices are unreasonable in mechanics design, and whole device is firm not, and this can cause the figure and the figure in ideal that draw to produce dimensionally larger gap.Secondly, the structure too complex of these devices, uses underaction convenient, is difficult to significantly improve the efficiency of drawing on blackboard.Moreover, use these devices on blackboard, to paint bowlder along with the chalk radius of a circle that shortens gradually can diminish gradually.Therefore in the integration of drawing tools, also has very large space.How further to integrate these independently drawing tools, and it is simple in structure to make new drawing tools have, it is flexible, convenient to use, and can effectively improve the advantage of the drawing efficiency on blackboard, the problem of primary thinking while becoming design drawing tools.
Summary of the invention
The invention provides a kind of multifunctional ruler, solve current similar picture chi complex structure, flexibility ratio is poor and service efficiency is not high problem.
Multifunctional ruler of the present invention mainly comprises transverse axis and vertical pivot part, and vertical pivot is perpendicular to transverse axis; Parallel with vertical pivot and ganoid sliding bar passes and is fastened to the surface of vertical pivot from the inside of locator; Locator can move up and down but can not rotate along sliding bar; The crown center place of locator is provided with fixed screw, the center line of fixed screw and the center line of sliding bar is orthogonal and in same plane; Chalk double-layered quilt is fixed on locator and the close side of sliding bar; At the two ends of transverse axis and the bottom of pin, be provided with removable fixing glue; Transverse axis inside is provided with cavity---chute, the smooth and transverse axis of detent surface; In the inside of chute, inlaying the sliding shoe that can move left and right one by one in chute; The lower end of vertical pivot is fixed on sliding shoe by pin, and whole vertical pivot part can move left and right along transverse axis under the regulation of sliding shoe; On vertical pivot and transverse axis, be all provided with length scale.
Vertical pivot and transverse axis in described multifunctional ruler are orthogonal, after zero graduation line on length scale and vertical pivot extends by the center of circle of pin.
In described a kind of multifunctional ruler, length graduated scale, on vertical pivot and transverse axis, can be recorded to the distance that locator moves accurately, thereby draw accurately the line segment of designated length in certain maximum and the circle of appointment radius.
Fixing glue in described a kind of multifunctional ruler can be that sucker can be also magnet, utilize atmospheric pressure and vacuum principle, as long as then the part air extruding in sucker inner chamber is closely pressed in him on the surface of smooth and face seal, CD just can be inhaled steady, and under the prerequisite that does not depart from smooth surface, allows to hang up certain weight.Using magnet is to have utilized the magnetic material principle that there is a natural attraction between the sexes as fixing glue, at present nearly all blackboard for education, is all provided with magnet, and this provides condition as fixing glue for select magnet.
Multifunctional ruler, by the combination of cross bar and montant, is added slide block and is coordinated with the ingenious of slide bar, chute, has realized cleverly the integration to multiple independent drawing tools such as ruler, set square, compasses.The rotating shaft of drawing circle swing arm is arranged in the plane of multifunctional ruler, by fixing glue, replaces the fixedly stitch of compasses, solved the problem that needle of compasses easily scratches blackboard, easily user damaged.Such design has also solved uses general compasses on blackboard, to paint bowlder along with the chalk problem that radius of a circle can diminish gradually that shortens gradually.Therefore multifunctional ruler of the present invention has simple in structurely, uses flexibly, convenient, can effectively improve the advantage of the drawing efficiency on blackboard.
accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-fixing glue, 2--transverse axis, 3-chute, 4-fixed screw, 5-locator, 6-pin, 7-sliding shoe, 8-sliding bar, 9-vertical pivot, 10-chalk folder, 11-length scale.
The specific embodiment
The invention will be further described with reference to the accompanying drawings and in conjunction with the specific embodiment below.
As shown in Figure 1, multifunctional ruler of the present invention mainly comprises transverse axis 2 and vertical pivot 9 two large divisions, and vertical pivot 9 is perpendicular to transverse axis 2.Sliding bar 8 parallel and ganoid with vertical pivot 9 passes and is fastened to the surface of vertical pivot 9 from the inside of locator 5.Locator 5 can move up and down but can not rotate along sliding bar 8, and the crown center place of locator 5 is provided with fixed screw 4, and the center line of the center line of fixed screw 4 and sliding bar 8 is orthogonal and in same plane.Chalk folder 10 is fixed on locator 5 side close with sliding bar 8.At the two ends of transverse axis 2 and the bottom of pin 6, be provided with removable fixing glue 1, transverse axis 2 inside are provided with cavity chute 3, and chute 3 smooth surfaces are parallel with transverse axis 2, are inlaying the sliding shoe 7 that can move left and right in chute one by one in the inside of chute 3.The lower end of vertical pivot 9 is fixed on sliding shoe 7 by pin 6, and whole vertical pivot 9 parts can move left and right along transverse axis 2 under the regulation of sliding shoe 7, on vertical pivot 9 and transverse axis 2, is all provided with length scale 11.
Draw parallel lines: first take off the fixing glue 1 of pin 6 bottoms, the fixing glue 1 at transverse axis 2 two ends is set up and transverse axis is fixed on blackboard; Next is tightened fixed screw 4 and locator 5 is fixed on to certain position of slide bar 8, to the upper chalk of chalk folder folder; Then allow whole vertical pivot 9 parts along transverse axis 2, move from left to right under the regulation of sliding shoe 7, by recording distance that sliding shoe 7 slips over, determine the length of institute's line drawing section; Finally by adjusting locator, determine the distance of two parallel lines, then repeat previous step, realize the function drawing parallel lines.
Draw rectangle, square and parallelogram: be to draw two groups of parallel lines in fact, as long as after painting first group of parallel lines, adjust the orientation of transverse axis 2 and draw again the figure that one group of parallel lines just can obtain expection.
Draw circle: first take off the fixing glue 1 at transverse axis 2 two ends, the fixing glue 1 of pin 6 bottoms is set up and transverse axis is fixed on blackboard, transverse axis 2 can be rotated freely along pin 6 on blackboard; Next is unscrewed fixed screw 4 locator 5 is slided into needed radius of circle length, then it is fixing locator 5 to tighten fixed screw 4, and to the upper chalk of chalk folder folder; Finally, allow whole device be close to blackboard far away pin 6 rotate a circle, realize the function of picture circle.
In sum, multifunctional ruler of the present invention is simple in structure, uses flexibly and easily, can significantly improve the efficiency of drawing on blackboard.
