Abstract
The utility model relates to a multifunctional drawing instrument. The utility model is characterized in that a triangular ruler (or a straight ruler) is provided with two circular grooves which are respectively provided with a compass and an electronic watch and is provided with an arc-shaped groove which is provided with a thermometer, the compass is covered by a cover body marked with a scale line (angle), and thereby, the drawing instrument has all functions of straight rulers, triangular rulers and protractors, and has the functions of time report, temperature measurement and direction identification at the same time.
Description
The utility model relates to a kind of multi-function drawing instrument of the usefulness of drawing.
Draw to mix with ruler, set square, protractor, compasses etc. usually and use, this method is generally adopted, and certain advantage is arranged.But the mixing of several instruments, chi is used, and makes the error of drawing bigger, and tight inadequately, standard simultaneously, are carried also inconvenient.
For addressing this problem, common way is to draw more patiently and carefully, but the efficient of doing like this is not high.
The purpose of this utility model is that a kind of multi-functional plotter will be provided.It has ruler, set square, protractor three's function simultaneously, has the function of giving the correct time, measure temperature, identification direction simultaneously.
The purpose of this utility model is achieved in that at a set square (as accompanying drawing) and goes up circular trough of brill 1., at electronic watch of central installation, bore a deep-slotted chip breaker 5., at compact temperature meter of central installation, bore a circular groove more 4., a small size compass is installed.4. bore an annular groove 3. on every side at circular groove, can rotate and graduated circular lid with one of civilian dress.Also all there is scale on three limits (as 2.) of set square simultaneously.
The utility model is simple in structure, has mainly utilized the compass direction never to become this principle design, does not have specific (special) requirements, is easy to carry simultaneously, has multiple function.
The concrete structure and the embodiment of utility model are as follows:
Accompanying drawings its concrete device and working condition.
This device comprise an electronic watch 1., thermometer 5., compass 4., a circular swivelling cover 3..
1. embodiment draws parallel lines.Draw straight line along any one side, mobile then ruler is observed compass to desired location, if pointer indication scale is constant, and drawn straight line and previous drawn straight line parallel then along the same side.
2. draw an angle, the characteristics of utilizing circular lid to rotate are adjusted its scale, make 0 ° of pointer indication scale, at this moment draw straight line down along any one side.Choose one of them end points then, around this end points rotation ruler, pointer deflects, and draws a straight line again along the same side, intersects with previous that, and the number of degrees of pointer institute deflection are the number of degrees at drawn angle.Certainly, do not adjust on the circular lid scale also can, like this, only need subtract each other the number of degrees of two deflections, get final product the number of degrees at angle.
3. measuring angle.Any one side of multi-function drawing instrument certain with the angle is alignd on one side, adjust the circular lid scale, make 0 ° of pointed, rotate ruler to another side along end points then, at this moment pointer indication scale is the angle at angle, to make the pointed scale be 0 ° if do not adjust scale, then calculates the difference that passes angle for twice partially and promptly get the scale at angle.
Claims (3)
1, a kind of multi-function drawing instrument is characterized in that on a set square or an electronic watch is housed on the ruler, a thermometer, and a compass, compass is covered by a graduated lid.
2, multi-function drawing instrument according to claim 1 is characterized in that a compass that can rotate freely is arranged on the chi body.
3, multi-function drawing instrument according to claim 1 is characterized in that the chi body or the lid of the face of overlooking at compass is marked with graduation mark (angle).
