Abstract
The utility model discloses a kind of multifunctional ruler, belong to mathematics teaching aid field.Its poly-several functions, can do set square use, also can be used as protractor and uses, set square hypotenuse chi also can be used to use as ruler, and can extended length when hypotenuse chi length is inadequate, to meet user demand, for teaching provide greatly convenient.Protractor is fixedly mounted on square minor face side, and interior chi and outer chi are slidably connected, and interior chi outer end and protractor are rotationally connected, and outer chi outer end is installed with fixed leg, and there is a gap the long chi side of square.The utility model gathers several functions, can do set square use, also can be used as protractor use, set square hypotenuse chi also can be used to use as ruler, and when hypotenuse chi length is inadequate extended length, with satisfied use, for teaching provide great convenience.
Description
Technical field
The utility model relates to a kind of multifunctional ruler, belongs to mathematics teaching aid field.
Background technology
Present set square for teaching, can only singlely use as set square, when using as ruler, when drawn line segment length is greater than the limit of set square, just must again put set square and continue picture, and in mapping process, blade easily slides, cause drawn straight line not straight, mapping is wasted time and energy, and function singleness, cannot use as protractor, each teaching all will carry a large amount of teaching aid, brings great inconvenience to teacher, and the switching of multiple teaching aid uses and also makes valuable instructional blocks of time be wasted in vain.
Summary of the invention
The purpose of this utility model proposes a kind of multifunctional ruler, its poly-several functions, set square can be done use, also can be used as protractor to use, also set square hypotenuse chi can be used to use as ruler, and can extended length when hypotenuse chi length is inadequate, to meet user demand, for teaching provide greatly convenient.
The technical solution of the utility model is: a kind of multifunctional ruler, comprise interior chi, outer chi, fixed leg, protractor and square, described protractor is fixedly mounted on square minor face side, described interior chi and outer chi are slidably connected, and interior chi outer end and protractor are rotationally connected, outer chi outer end is installed with fixed leg, and there is a gap the long chi side of square.
The beneficial effects of the utility model are: the utility model is while using as set square, also can be used as protractor to use, also set square hypotenuse chi can be used to use as ruler, and when hypotenuse chi (namely chi and outer chi) length is inadequate extended length, with satisfied use, it is greatly convenient to provide for imparting knowledge to students.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of multi-functional triangular ruler of the present utility model;
Fig. 2 is the sectional view of the set square hypotenuse chi of Fig. 1.
Wherein, 1-1 comprises interior chi, 1-2 outer chi, 1-3 fixed leg, 1-4 subsidiary line, 2 protractors, 3 squares.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Figure 1-Figure 2, a kind of multifunctional ruler, comprise interior chi 1-1, outer chi 1-2, fixed leg 1-3, protractor 2 and square 3, described protractor 2 is fixedly mounted on square 3 minor face side, described interior chi 1-1 and outer chi 1-2 is slidably connected, and interior chi 1-1 outer end and protractor 2 are rotationally connected, outer chi 1-2 outer end is installed with fixed leg 1-3, there is a gap the long chi side of square 3.
Preferably, as shown in Figure 1, protractor 2 is circular.
Further, as shown in Figure 1, interior chi 1-1 rotates around the center of circle of protractor 2.
Further, as shown in Figure 1, when multifunctional ruler is set square state, fixed leg 1-3 just embeds in the gap of the long chi side of square 3.Spacing by gap, make the triangle state that multifunctional ruler becomes stable.
Further, as Figure 1-Figure 2, be provided with a sliding tray in outer chi 1-2, interior chi 1-1 shape and this sliding tray coincide.When hypotenuse chi uses as ruler, if length not, can extend.
Further, described multifunctional ruler material therefor is transparent plastic, is convenient to line and takes measurement of an angle.
Further, as shown in Figure 1, the centre on interior chi 1-1 and outer chi 1-2 is provided with a subsidiary line 1-4 along its length.
When multifunctional ruler uses as protractor, rotatable hypotenuse, aims at the point or line that will measure, to take measurement of an angle by subsidiary line.
