Description
The utility model belongs to drawing appliance, is a kind of multipurpose drawing set square.Be applicable to engineers and technicians, teacher, the student of college and middle school student.
No matter do engineering design or drafting engineering drawing at present, as machine drawing, electrical diagram, architectural drawing, mining figure or the like, all need to prepare several drawing instruments, a secondary set square, compasses, spline, protractor will be arranged at least, existing common drawing instrument generally is a singlepiece, a function is drawn the circle compasses, draws the straight line set square, trace is with curve ruler etc., so not only troublesome poeration carries also inconvenience, and loses easily.
The purpose of this utility model is to provide a kind of drawing accurate, allround plotter easy to use.
The purpose of this utility model is achieved in that this plotter is the right angle triangle that one two base angle is respectively 30 ° and 60 °.On this set square, make to have a right angle bisector,, 30 ° of angular bisectors, two parallel lines vertical with long rightangle side are made to have in middle part at set square, article two, between the parallel lines scale is arranged, on three limits of set square, three kinds of instruments are housed respectively, on the short rightangle side pointer protractor is housed, guide tracked compasses are housed on the hypotenuse, guide tracked curve ruler is housed on the long rightangle side, and except that curve ruler was taken off use, other utensil all was fixed on the set square and uses.Only, just can draw straight line, parallel lines, vertical line, curve and garden with a such set square.
The utility model is reasonable in design, and compact conformation is multiple functional, and is easy to use, degree of accuracy height, and cheap, easy to carry, manufacturing process is simple, saves raw material.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is allround plotter general assembly schematic diagram (Figure of abstract)
Fig. 2 is pointer protractor schematic diagram
Fig. 3 is the curve ruler structural representation
Fig. 4 implements illustration
41 is a 45, the practice at 75 ° of angles and 105 ° of angles:
42 is 15 ° the practice; 43 is the practice of parallel lines;
44 is the practice of vertical line; 45 is the practice of six five equilibriums of circle;
46 is the usage of protractor.
In the accompanying drawing: the 1st, Line 1,2 is No. 2 lines, and 3 is No. 3 lines, and 4 is No. 4 lines, the 5th, scale, the 6th, the polygon that cuts out, the 7th, the clamp of band screw, the 8th, spline connecting screw, the 9th, guide plate, the 10th, spline, the 11st, compasses guiding device, the 12nd, paintbrush, the 13rd, paintbrush connecting screw, the 14th, center of circle pin connecting screw, the 15th, center of circle pin, the 16th, handle, the 17th, handle connecting screw, the 18th, pointer, the 19th, pointer connecting screw, the 20th, protractor dial.
The main body of this plotter is that two base angles are respectively the right angle triangles of 30 ° and 60 °.This above set square work four lines are arranged: article one line is a right angle bisector 1, claims Line 1, and Line 1 cooperates with long rightangle side can draw 45, cooperates with hypotenuse to draw 75 ° of angles and 105 ° of angles.The concrete practice is: as figure (41), with the Line 1 on the set square, pressed and overlapped is on the known line (thick chaindotted line) of drawing, and along rightangle side settingout (heavy line), the angle between thick chaindotted line and the heavy line promptly is a 45.Along the angle between hypotenuse settingout and the known line promptly is 75 ° of angles and 105 ° of angles.The method of abovementioned mapping claims with line pressure line drawing collimation method.The line of drawing other also uses the same method.The second line is 30 ° of angular bisectors 2, claims No. 2 line, and No. 2 lines cooperate with long rightangle side or hypotenuse can draw 15 ° of angles (as Fig. 42).Article three, line and the 4th line are vertical with long rightangle side two lines that are parallel to each other 3 and 4, divide No. 3 lines of another name and No. 4 lines, between No. 3 lines and No. 4 lines scale 5 is arranged, cooperate to draw parallel lines (as Fig. 43) with long rightangle side with abovementioned No. 3 lines or No. 4 lines and scale 5.Cooperate with long rightangle side with No. 3 lines or No. 4 lines and can draw vertical line, cross hairs (as Fig. 44).Hypotenuse with the cross centre line of circle and No. 3 lines or No. 4 lines and set square cooperates, and can make six five equilibriums of justifying (as Fig. 45).Between Line 1 and No. 4 lines, a polygon that cuts out 6 is arranged, can directly make 45 °, 105 °, hexagonal angle with it.Generally speaking, utilize a such set square, can draw straight line, vertical line, parallel lines, 15 ° multiple angle and three, four, six, eight, ten bisections of circle.
On three limits of abovementioned set square, three kinds of instruments are housed respectively, guide tracked compasses are housed on the hypotenuse, on the short rightangle side pointer protractor is housed, two clamps 7 of being with screws are housed on the long rightangle side, be used for the guide tracked curve ruler of card.
Guide tracked compasses and general compasses are basic identical, handle 16, center of circle pin 15 and paintbrush 12 are arranged, and different is that these compasses have a guiding device 11, and guiding device 11 is parallel with hypotenuse, it can be to give a groove that stays on the set square, also can be a guide rail of loading onto in addition.One end of guiding device has center of circle pin 15, is connected on the guiding device 11 with screw 14, and center of circle pin can rotate around screw 14.The other end has paintbrush 12, is connected on the guiding device with screw 13, and paintbrush can rotate around screw 13, can also slide along guiding device, not the time spent, center of circle pin 15 and paintbrush 12 can be gone to the position that overlaps with guiding device.Top end at the set square right angle has handle 16, handle 16 usefulness screws 17 are loaded onto, be vertical with hypotenuse, and with center of circle pin 15 on same the straight line, handle can be turned back, time spent not, handle is turned back on the set square, during use, unclamps screw 17, with the turn back outside on top, right angle of handle 16, fixed screw 17.Unclamp screw 14 simultaneously, center of circle pin 15 is forwarded to vertical, and aim at scale " 0 " on the hypotenuse, fixed screw 14 with hypotenuse.Unclamp screw 13 again, paintbrush 12 forwarded to vertical, on the scale of hypotenuse, get radius with paintbrush 12 with hypotenuse, aim at required numerical value after, fixed screw 13.Get final product the picture circle, with handle, center of circle pin and paintbrush return on the original position after painting.
Protractor is pointer, and pointer 18 is close to short rightangle side and is put, and has screw 19 that pointer is fixed at the middle part of pointer 18, or freely rotates.Between Line 1 and short rightangle side, one 1/4 circle is arranged, on this circular arc scale is arranged, weighing hornwork dial 20.During use, unclamp screw 19 pointer 18 is aimed at the number of degrees that will get on the dials 20, fixed screw 19 again, respectively draw straight line along pointer 18 or short rightangle side, and the angle between two lines is exactly the angle (Fig. 56) that will draw.
Guiding type curve ruler: form by guide plate 9 and spline 10.Spline 10 links together with two screws 8 of guide plate 9 usefulness, and spline can slide on guide plate.During use, unclamp screw 8, two screws are relatively moved, then spline bending, when bending to needed shape, fixed screw 8 is lived guide plate 9 with hand, and along the spline settingout, the line that draws promptly is needed curve.After using up, unclamp screw 8, spline restored to the original state, on the long rightangle side of set square, the clamps 7 of two band screws are housed, block curve ruler usefulness, curve ruler not the time spent be stuck on the set square, the time spent is taken off, clamp 7 also can be contained on the short rightangle side.
This plotter all can be made of lucite, duroplasts, metal, timber etc.And can make all size as required.
