Abstract
The utility model discloses a multifunctional ruler, comprising a ruler body, wherein the ruler body is provided with an angle gauge, the angle gauge is parallel to the ruler body, the center of the angle gauge is connected with a measuring wire, and one end of the measuring wire is connected with a heavy punch; in the multifunctional ruler, the angle gauge and the heavy punch of the measuring wire are arranged on the ruler body, the measuring wire always keeps perpendicular under the action of the heavy punch, when the ruler body rotates for a certain angle on the plane, the measuring wire also rotates for an angle same as that of the ruler body, so that the rotation angle of the ruler body can be read; the multifunctional ruler not only has functions of a conventional ruler, but also has such functions as drawing parallel lines, measuring angles, bisecting angles and the like, so that the multifunctional ruler facilitates operations of measuring and drawing, and is particularly suitable for teaching demonstration in classroom.
Description
Technical field
The utility model relates to a kind of measurement drawing instrument, is specifically related to a kind of ruler.
Background technology
Ruler function in the market is comparatively single, generally can only draw straight line or measure length, in order to realize drawing parallel lines, angulation, to divide functions such as angle equally, need to use other instrument or a plurality of tool combinations to use, operation is very inconvenient like this, especially in the teaching, the teacher need demonstrate on blackboard, and a plurality of tool combinations are inconvenience more.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of multifunctional ruler, except that the function with traditional ruler, can also realize drawing parallel lines, angulation, divide multiple functions such as angle equally.
Multifunctional ruler of the present utility model comprises blade, and described blade is provided with the protractor parallel with blade, and the protractor center is connected with criterion, and criterion one end is connected with weight.
Further, the range of described protractor is 0 ~ 360 degree;
Further, described blade is marked with the length scale;
Further, described blade is a set square.
The beneficial effects of the utility model are: the utility model is by being provided with protractor and criterion weight on blade, criterion remains under the effect of weight vertically, when blade turns an angle in the plane, criterion also turns over an angle and identical with the angle of blade rotation on protractor, therefore can read the angle that blade rotates, utilize this principle can realize angulation, divide function such as angle equally; Draw straight line earlier, the angle that the control blade rotates when drawing the second straight line is 0, can guarantee second straight line and article one straight line parallel, has realized the function that draws parallel lines; The utility model can also be realized drawing parallel lines, angulation, divide multiple function such as angle equally except that the function with traditional ruler, has made things convenient for the measurement mapping operation, is particularly useful for the classroom instruction demonstration.
Description of drawings
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Fig. 1 is a structural representation of the present utility model, and as shown in the figure, multifunctional ruler of the present utility model comprises blade 1, and described blade 1 is provided with the protractor 2 parallel with blade 1, and protractor 2 centers are connected with criterion 3, and criterion 3 one ends are connected with weight 4.When using the utility model angulation, make criterion 3 vertical naturally earlier with weight 4, the sideline of blade 1 overlaps with the one side at angle, read the angle of criterion 3 correspondence on protractor 2, rotate blade 1 then, forward the sideline of blade 1 to overlap position, read the angle of criterion 3 correspondences this moment with the another side at angle, front and rear angles subtracts each other, and can obtain the number of degrees at angle; Dividing the angle equally also is similar operation; When using the utility model to draw parallel lines, make criterion 3 vertical naturally earlier with weight 4, straight line is drawn in sideline near blade 1, read the angle of criterion 3 correspondence on protractor 2,1 to second position of mobile then blade, the angle of control criterion 3 correspondence on protractor 2 is constant, draws the second straight line, can guarantee second straight line and article one straight line parallel.
As further improvement of the utility model, the range of described protractor 2 is 0 ~ 360 degree; The range of protractor 2 is the whole circumference angle, and more convenient operation is avoided the reading blind area.
As further improvement of the utility model, described blade 1 is marked with the length scale; Make and the utlity model has the function that traditional ruler is measured length.
As further improvement of the utility model, described blade 1 is a set square; Make to the utlity model has the function that special angle was measured, drawn to the traditional triangle chi fast, and set square is convenient to hand-held operation.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although by the utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and the spirit and scope of the present utility model that do not depart from appended claims and limited.
Claims (4)
1. a multifunctional ruler comprises blade, it is characterized in that: described blade is provided with the protractor parallel with blade, and the protractor center is connected with criterion, and criterion one end is connected with weight.
