The utility model is described further with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of Multifunctional drawing teaching aid, rotary scale 1 and pedestal scale 2；Rotary scale one end and pedestal
Scale one end partially overlaps, and is respectively formed coincidence part, and be relatively fixed by connector 3；Rotary scale 1 can surround connector 3
Rotation；Hollow out circular arc 4 is arranged in rotary scale coincidence part, and angle indicator 5 is provided in the middle part of hollow out circular arc；On pedestal scale coincidence part
It is provided with angle index, angle index can pass through hollow out circular arc and show；There is scale bar groove 6 on pedestal scale, is set in scale bar groove
It is equipped with focus knob 7, focus knob can slide in scale bar groove and keep being relatively fixed.
As shown in Fig. 2, rotary scale includes ontology I 8, protrusion, i.e. scale lock 9 is arranged in ontology one end；Ontology 8 is another
Half-round I 10 is arranged in end；I 10 upper surface of half-round is for the same side with body upper surface and I thickness of half-round is less than ontology thickness
Degree.Hollow out circular arc 4 is set in rotary scale half-round I, angle indicator 5 is provided in the middle part of hollow out circular arc.Rotary scale surface
Upper edge and lower edge are respectively provided with length scale.
As shown in figure 3, pedestal scale includes ontology II 11, groove 12 is arranged in ontology one end, does not have to state in drawing teaching aid
Under, groove 12 can latch 9 with scale and be fixed.Half-round II 13 is arranged in the ontology other end；II lower surface of half-round and ontology
Lower surface is for the same side and II thickness of half-round is less than body thickness.There is scale bar groove 6 on pedestal scale, is arranged in scale bar groove
There are focus knob 7, focus knob that can be slided in scale bar groove and keep being relatively fixed.The upper edge and lower edge on pedestal scale surface
It is respectively provided with length scale.
As shown in Fig. 1,4,5, pedestal scale is fixed with slide plate public affairs slot 14 close to II side of half-round by bonding way, sliding
Slide scale 15 is set on plate public affairs slot 14.The utility model slide plate public affairs slot structure is that a pair is arranged in I 16 upper surface of block-shaped body
Parallel protrusion sliding rail 17；Slide scale structure is that a pair of parallel strip groove 19 is arranged in II 18 lower surface of block-shaped body；Sliding rail
17 install with the cooperation of strip groove 19 so that slide scale can slide on slide plate public affairs slot.The utility model is on slide scale
It is also equipped with scale bar groove, focus knob is provided in scale bar groove, focus knob can slide in scale bar groove and keep phase
To fixation.Meanwhile rotary scale side being provided with length scale in slide scale upper surface.
Utility model device overlaps half-round I with half-round II in assembly, and passes through half-round by connector
I is relatively fixed one end of rotary scale and pedestal scale with half-round II.Made with the breakthrough point of rotary scale and pedestal scale
For the central point of protractor, II upper surface of pedestal scale half-round is provided with angle index, angle index can pass through hollow out circle
Arc is observed；After assembly, half-round I and the thickness being added of half-round II are identical as the thickness of rotary scale, pedestal scale.So
Afterwards, slide plate public affairs slot is bonded in II side of half-round, by slide scale assembly on slide plate public affairs slot.Slide plate public affairs slot and slide scale
The sum of thickness is equal to or less than II thickness of half-round.In this way when rotary scale 1 rotates, slide plate public affairs slot will not be hindered with slide scale
Gear, influences to rotate.
Utility model device application method is as follows：
Angle is drawn, scale lock 9 is broken into two with one's hands, will be basic point with connector 3, be formed between rotary scale 1 and pedestal scale 2
Angle, angle reach required angle, the length scale that the length of side passes through rotary scale and pedestal scale by rotation angle pointer 5
To determine having along rotary scale lower edge, pedestal scale upper edge by pen, you can complete picture angle.
Ellipse is drawn, by adjusting two focus knobs with fixed pedestal scale 2 or slide scale 15, is determined oval burnt
Away from then the swinging arms for having regular length line segment of connection peripheral hardware, swinging arms are oval around the track of focus rotation.
Oval size and specification are realized by adjusting the length of focal length and line segment.
It draws parallel lines, parallel lines stretch out the distance of rotary scale upper edge by slide scale by sliding slide scale 15
It determines distance between parallel lines, then determines equality line endpoints position, along the side of rotary scale upper edge carry out setting-out.
Pedestal scale and slide plate public affairs slot in specific implementation, can also be designed integrated whole knot by the utility model
Structure, rather than separate part.Plastic expansion screw may be selected in the focus knob of the utility model, and quarter is fastened on by setscrew
It spends and realizes fixation in bar groove, by mediating setscrew, it is allowed to move.The utility model connector can be shaft member, on the one hand
It allows rotary scale and pedestal scale to be relatively fixed, does not depart from；On the other hand allow rotary scale that can be rotated by axle center of connector.
All above-mentioned this intellectual properties of primarily implementation, there is no this new products of implementation of setting limitation other forms
