Abstract
The utility model relates to a multifunctional drawing board, which is characterized in that a straight rule lies across a drawing board, one end of the straight rule is in sliding connection with the left end of the drawing board, one end of the drawing board is provided with a slide way, the lower face of the straight rule is fixed with a slide block which is down in the slide way, and the straight rule can travel up and down parallelly along the slide way; a semi-circle rule is sheathed on the straight rule and can make crosswise slide on the straight rule, an acute angle of a right-angle set square is arranged on a central axis of the semi-circle rule, the right-angle set square can be rotated around the central axis, and the other acute angle is provided with a pen hole for drawing a circular arc. The utility model has the advantages of compact structure, easy use and multiple functions.
Description
The utility model belongs to a kind of drawing board.
Present drawing board mainly contains following several: 1, ruler: be used for drawing straight line; 2, protractor: be used for drawing angle line; 3, T-square: be used for drawing parallel lines and vertical line; 4, set square: be used for drawing straight line and the standardized corner angle staff of deciding angle (30 °, 45 ° and 60 °).Obvious above-mentioned four kinds of drawing board function singlenesses.
The purpose of this utility model provides a kind of with above-mentioned functions collection multifunctional drawing board all over the body.
The purpose of this utility model is achieved in that ruler is horizontal on drawing board, and an end of ruler and the left end of drawing board are slidingly connected: an end of drawing board has chute, fixing slide block below the ruler, down in chute, slide block has centre bore, and this bottom, hole flare (tapering is promptly arranged) is in this horn mouth, a nut is arranged, its outside also has tapering, is lock dog, and respectively there is a screw at the two ends above the slide block, penetrate in slide block centre bore and the lock dog, lock dog and slide block are all made with elastomeric material.Unclamp screw, screw is up, and lock dog shrinks, and slide block also shrinks, slide block increases in the gap of chute, and slide block can slide up and down along chute, and ruler also along with parallel mobile up and down, is tightened screw, screw is descending, and lock dog expands, and slide block also expands, and slide block is located in chute.The semicircle chi is enclosed within on the ruler, and the semicircle chi can laterally slide on ruler, and an acute angle drift angle of drawing square is fixed on the axle of semicircle chi garden, and drawing square can rotate around the axis.On another acute angle drift angle, a hole is arranged, be used for drawing circular arc.
Using method is: at first complete drawing paper on the plate face, when T-square, unclamp screw, can move up and down ruler, tighten again, fixedly ruler, when drawing vertical line, a right-angle side of set square is placed on the ruler, when drawing oblique line, rotates set square, can mark the oblique line of required angle according to the scale of semicircle chi, when making an arc line, nib is inserted in the hole line of can making an arc.
The utility model compared with prior art has the advantage of compact conformation, easy to use, multiple function.
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is a front view of the present utility model.
Fig. 2 is the cutaway view of Fig. 1 along the A-A line.
Fig. 3 is the cutaway view of Fig. 1 along the B-B line.
