Summary of the invention
The utility model provides a kind of multifunctional ruler, solves current similar picture chi complex structure, flexibility ratio is poor and service efficiency is not high problem.
Multifunctional ruler of the present utility model 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; Be provided with removable fixing glue at the two ends of transverse axis and the bottom of pin; Transverse axis inside is provided with cavity---chute, the smooth and transverse axis of detent surface; Inlaying the sliding shoe that can move left and right one by one in chute in the inside of 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 on 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, replaces the fixing stitch of compasses by fixing glue, solved needle of compasses and easily scratched blackboard, the easy problem that user is damaged.Such design has also solved and has used 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 utility model has simple in structurely, uses flexibly, convenient, can effectively improve the advantage of the drawing efficiency on blackboard.
