Description
Technical field
The utility model relates to a kind of drawing ruler for teaching, belongs to study article technical field of structures.
Background technology
Drawing rule is the schooling apparatus that Student Mathematics class is conventional, and existing drawing rule structural design is single, only has drawing function, again without other use, and drawing rule generally includes ruler, set square, semi-circle ruler, and three rulers are separate, easy loss, uses very inconvenience.
Summary of the invention
The purpose of this utility model is the weak point solving prior art existence, provides a kind of easy to use, has bookshelf effect concurrently, the drawing ruler for teaching not easily lost.
The utility model is achieved through the following technical solutions:
A kind of drawing ruler for teaching, its special character is to comprise on length direction establishes graduated ruler body 1, ruler body 1 is hollow structure, the upper surface length direction of ruler body 1 is provided with strip opening 2, discoid rotatable lamella 3 is embedded with in ruler body 1, the top of rotatable lamella 3 is provided with pillar 4, the top of pillar 4 is provided with horizontal cross bar 5, the upper surface length direction of horizontal cross bar 5 is provided with two blend stop I6 separately, blend stop II15, the upper surface of ruler body 1 is also provided with two deployable or draw in support bars 7, two support bars 7 lay respectively at the both sides of strip opening 2, rotatable lamella 3 is provided with two through holes 8, on through hole 8, bolt has stay cord 9, the both sides of ruler body 1 are provided with for the eyelet through stay cord 9, one end that two stay cords 9 are positioned at ruler body 1 outside is installed on joint pin I11 respectively, on joint pin II12, joint pin I11, the bottom of joint pin II12 is fixed with set square 13 respectively, semi-circular plate 14,
The upper surface position on the right side of ruler body 1 is all fixed in one end of described two support bars 7;
The height of described blend stop I6 is less than the height of blend stop II15, and the top of blend stop I6 is provided with two rotating blocking arms 16.
A kind of drawing ruler for teaching of the present utility model, smart structural design, ruler body, set square, semi-circular plate is connected as one by stay cord, not easily lose, easy to use, if when using as bookshelf, only horizontal cross bar need be rotated, make horizontal cross bar and ruler body perpendicular, the two is in cross, textbook is positioned on horizontal cross bar, by blend stop I, blend stop II clamps books, textbook is propped up by blocking arm, expansion supporting rod, make support bar and ruler body perpendicular, support bar can prop up after textbook, play a supporting role, when not using, rotate horizontal cross bar, horizontal cross bar is paralleled with ruler body, support bar is drawn in.In sum, drawing ruler for teaching of the present utility model is easy to use, reasonable in design, has good application prospect in mathematical studying field.
