Abstract
The utility model provides a three-view plotting instrument which comprises a locating guiding block, a transposition guiding ruler, a first plotting ruler, a second plotting ruler, a spring and the like. A three-needle locating base is arranged on the lower portion of the locating guiding block, a guiding block is arranged in the middle, a guiding ruler pressing plate is arranged on the upper portion, and equidistant guiding faces are arranged on the guiding block in the horizontal direction, the vertical direction and the 135-degree direction. A hinge joint pin and two limiting pins are arranged at the left end of the transposition guiding ruler, a transposition hole is formed in the middle of the transposition guiding ruler, and a guiding groove is formed in the right end of the transposition guiding ruler. A hinge joint hole and a limiting hole groove are formed in the middle of the connecting position of the first plotting ruler and the second plotting ruler, a straight edge is arranged on a half of the end face, a 45-degree slant edge is arranged on the other half of the end face, and transition between a straight ruler and an angle ruler can be achieved. When the three-view plotting instrument is used, the transposition hole of the transposition guiding ruler is aligned with the locating guiding block, the transposition guiding ruler rotates around the locating guiding block to be in the horizontal direction, the vertical direction or the 135-degree direction, the first plotting ruler and the second plotting ruler are limited in the straight ruler state or the 90-degree angle ruler state, and the projection plotting requirements for the aligned lengths, the flush heights and the equal widths of three views can be conveniently achieved under guiding of the transposition guiding ruler and the locating guiding block.
Description
Technical field
The utility model relates to the drawing instrument in Graphing of Engineering, specifically a kind of convenient drawing instrument of drawing three-view diagram.
Background technology
The drafting of Graphing of Engineering three-view diagram is the necessary drafting with rules and compasses training of Engineering Students.Compasses, set square and pencil that the drawing instrument of engineering and polytechnic universities' drafting with rules and compasses is provided for oneself except student, also have chart board and T-square; Useful plastics chart board adds the drawing instrument that right angle work rest blade replaces traditional chart board and T-square on the market at present, but still does not change traditional drawing principle and method.But, the application of " length aligns, height is concordant, wide equates " that student requires for three-view diagram in drawing is skilled not, particularly " bow, left view wide equate ", some students even also will use 45 ° of boost lines, thereby cause drawing efficiency lower or " third-class relation " make mistakes.For this reason, design is a kind of can simple, conveniently draw three-view diagram, and easily guarantees the drawing instrument of " third-class relation ", necessary for the training of Engineering Students Graphing of Engineering.
Summary of the invention
The utility model is drawn lower or " third-class relation " problem of makeing mistakes of drawing efficiency in three-view diagram process for fear of student, specially proposes a kind of three-view diagram plotter.
The technical solution of the utility model is for this reason: three-view diagram plotter, comprise positioning and guiding piece, transposition work rest blade, drawing rule one, drawing rule two, positioning and guiding piece bottom is three pin positioning bases, centre is guide pad, top is work rest blade pressing plate, it is characterized in that: guide pad level, vertically and 135 ° of directions be provided with equidistant spigot surface; Transposition work rest blade left end has a swivel pin and two spacer pins, and middle is transposition hole, and right-hand member is gathering sill; Drawing rule one and drawing rule two chi face both sides are provided with scale, in the middle of junction, be provided with hinge hole and spacing hole slot, the end face half of drawing rule one and drawing rule two is straight flange, second half is 45 ° of hypotenuses, by spacer pin in transposition work rest blade be fixed on spring on drawing rule one and drawing rule two and realize the conversion of ruler and angle square and spacing.
Beneficial effect:
The utility model is fixed on three pin positioning bases of positioning and guiding piece in the middle of the drawing being laid on chart board in use; Transposition work rest blade is installed by transposition hole in positioning and guiding piece; Drawing rule one is connected with its hinge hole by the swivel pin in transposition work rest blade with drawing rule two; Rotate drawing rule one and drawing rule two, by spacer pin in transposition work rest blade be fixed on spring on drawing rule one and drawing rule two and realize the conversion of ruler and angle square and spacing.
When use, by the transposition hole of transposition work rest blade and positioning and guiding piece centering, go to level around it, drawing rule one and drawing rule two are limited in vertical ruler state, by the horizontally-guided of transposition work rest blade and positioning and guiding piece, can make drawing rule one and drawing rule two move left and right, realize projection main, that top view length aligns and draw.
By the transposition hole of transposition work rest blade and positioning and guiding piece centering, go to vertically around it, drawing rule one and drawing rule two are limited in the ruler state of level, by the vertical guiding of transposition work rest blade and positioning and guiding piece, can make drawing rule one and drawing rule two move up and down, realize main, the high concordant projection drawing of left view.
By the transposition hole of transposition work rest blade and positioning and guiding piece centering, go to 135 ° around it, drawing rule one and drawing rule two are limited in the angle square state of 90 °, by 135 ° of guiding of transposition work rest blade and positioning and guiding piece, can make drawing rule one and drawing rule two bow left synchronous, realization is bowed, the wide equal projection of left view is drawn.
The utility model adapts to the ruler training of three-view diagram, meets that three-view diagram length aligns, high concordant, wide equal projection drawing requirement.
