Description
Technical field
The utility model belongs to teaching aid equipment technical field, and in particular to a kind of combined type drawing instrument.
Background technology
In middle and primary schools' teaching process, due to the needs of drawing, teacher needs to use ruler, compasses, set square, protractor
Etc. a variety of drawing instruments, upper class hour, teacher need to carry multiple drawing instruments, carrying trouble every time；During drawing geometric figures, need
Drawing instrument is frequently changed, so greatly reduces drawing efficiency.Existing patent《Multifunction combined drawing instrument》(specially
Profit number：CN2014202800651, publication number：CN203920156U, publication date：Although the drawing instrument energy in 2014-11-05)
Drawing efficiency is enough improved, but because it carries out using protractor the drafting of angle etc., volume is larger, inconvenient to carry, during use
Cause certain trouble.
Utility model content
The purpose of this utility model is to provide a kind of combined type drawing instrument, and it is single to solve existing drawing instrument function,
The problem of volume is larger.
A kind of combined type drawing instrument of the utility model is the technical scheme adopted is that including ruler a, ruler a one end leads to
Cross bearing pin with ruler b ends to be connected, along ruler a and ruler b length to T-slot is distributed with, set in the T-slot on ruler a
The bolt a being matched therewith is equipped with, bolt a ends are socketed with nut a；It is provided with what is be matched therewith in T-slot on ruler b
Nut b is socketed with bolt b, bolt b and its end is connected with sucker；Ruler a and ruler b junction are additionally provided with angulation dress
Put.
It is of the present utility model to be further characterized in that,
Scale is provided with ruler a and ruler b, and both of which is made up of organic clear glass.
Both ruler a and ruler b one end is rectangular, and the other end is in semicircular arc, and both semicircular arc phases
Together, both are connected at semi arch end.
The pen cap is also socketed with nut a, and the pen cap and sucker are located at same one end.
Bolt b length is not less than bolt a length.
Angle measurer includes being located at circular scale and pointer, and dial is located on ruler a and overlapped with its semicircular arc,
Pointer is located on ruler b and is in contact with dial.
The beneficial effects of the utility model are：A kind of combined type drawing instrument of the utility model is by using ruler, sucker
With being used cooperatively for the pen cap, dial and pointer, the different shapes such as triangle, circle, straight line can be conveniently drawn, while also may be used
Simple in construction with measurement angle size, length scale, small volume is vdiverse in function, there is good use value.
Brief description of the drawings
Fig. 1 is a kind of structural representation of combined type drawing instrument of the utility model；
Fig. 2 is a kind of side view of combined type drawing instrument of the utility model.
In figure, 1. ruler a, 2. bearing pins, 3. ruler b, 4.T type grooves, 5. bolt a, 6. nut a, 7. bolt b, 8. nut b,
9. sucker, 10. pens cap, 11. dials, 12. pointers.
Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of combined type drawing instrument of the utility model, as depicted in figs. 1 and 2, including ruler a1, ruler a1 one end pass through
Bearing pin 2 is connected with ruler b3 ends, along ruler a1 and ruler b3 length to being distributed with T-slot 4, the T-slot 4 on ruler a1
The bolt a5 being matched therewith inside is provided with, bolt a5 ends are socketed with nut a6；Be provided with T-slot 4 on ruler b3 with
Nut b8 is socketed with its bolt b7 being engaged, bolt b7 and its end is connected with sucker 9；Ruler a1 and ruler b3 connection
Place is additionally provided with angle measurer.
Scale is provided with ruler a1 and ruler b3, and both of which is made up of organic clear glass, is carried out as ruler
Measure length etc..
Both ruler a1 and ruler b3 one end is rectangular, and the other end is in semicircular arc, and both semicircular arcs
Identical, ruler a1 semi arch end setting is fluted, and ruler b3 semi arch end is convex, and groove and projection are engaged and led to
Bearing pin 2 is crossed to connect.
The pen cap 10 is also socketed with nut a6, and the pen cap 10 and sucker 9 are located at same one end, and chalk etc. is placed in the pen cap 10,
Coordinate with sucker 9 as compasses and use.
Bolt b7 length is not less than bolt a5 length, because bolt a5 end sets have the pen cap 10, its internal placement
Chalk etc., when bolt a5 is long, the effect of compasses is not easy to realize.
Angle measurer includes being located at circular scale 11 and pointer 12, dial 11 be located on ruler a1 and with its semi arch
Shape overlaps, and pointer 12 is located on ruler b2 and is in contact with dial 11, by rotating ruler a1 and ruler b3, the He of dial 11
Pointer 12 can measure different angles, draw circular arc or triangle of different angle etc..
The utility model measures air line distance by ruler a1 and ruler b3；By rotary ruler combination a1 and ruler b3, coordinate
12 measurable angular dimension of dial 11 and pointer；By placing chalk etc. in the pen cap 10, being used cooperatively with sucker 9 to draw
Circular arc, circle etc.；It is simple in construction, small volume, it is easy to carry, improves the efficiency of picture, there is good use value.
