Abstract
The utility model relates to a teaching tool, in particular to a multifunctional teaching ruler which comprises a ruler body. The obverse side of the ruler body is provided with a circular-arc-shaped handle, the inner side of the circular-arc-shaped handle is provided with three to five pits, and the height of the circular-arc-shaped handle is 7cm-15cm. The middle of the ruler body is provided with an angle gauge with scales, and the center point of the bottom edge of the angle gauge is provided with a telescopic rod which is hinged to the ruler body. The multifunctional teaching ruler solves the problem that an existing ruler cannot be easily held and cannot be used for angular measurement, thereby having extremely high promotional value.
Description
Technical field
The utility model relates to teaching instrument field, especially relates to a kind of multifunctional teaching ruler.
Background technology
Teaching ruler is indispensable aid in teaching, and teacher helps student and understands problem saying often can draw class hour.A multiple functional teaching ruler is not only easy to use, also can in teaching, promote operating efficiency.And the teaching ruler using in teaching is at present easy in the time drawing, and brings very large inconvenience to teacher.
Granted publication CN 103241038 A(application numbers 201310181009.2) Chinese patent literature a kind of teaching ruler is provided, comprising: tabular blade, also comprise suction block and protective layer, described suction block is embedded in described blade; Described protective layer is attached on a surface of described blade.Granted publication CN 202656728 U(application numbers 201220241155.0) Chinese patent literature a kind of teaching ruler is provided, comprise body and handle, it is characterized in that, at least one magnetic texure is set in described body.
Although existing teaching ruler is in use more convenient, most function ratio are more single.Generally speaking, also there is no the application at teaching field of teaching ruler that function is more complete.
Summary of the invention
The purpose of this utility model, is just to overcome above-mentioned shortcoming, and a kind of multifunctional teaching ruler providing.
The utility model is achieved in that a kind of multifunctional teaching ruler, comprises chi body, and the front of chi body is provided with circular arc handle, and the inner side of circular arc handle is provided with a 3-5 depression, and the height of circular arc handle is 7-15 centimetre; The middle part of chi body is provided with the protractor with scale, and the mid point on protractor base is provided with expansion link, and expansion link and chi body are hinged.
Preferably, the height of described circular arc handle is 10 centimetres.
Preferably, the inner side of circular arc handle is provided with 4 depressions.
Preferably, the front of described chi body is also provided with air-bubble level.
Preferably, the back side of described chi body is provided with 3 suckers, and sucker is positioned at 3 ends at the chi body back side.
The beneficial effects of the utility model are: this teaching ruler can rely on the prompting of level meter to draw horizontal line or triangle accurately, the circular arc handle of band depression can be fixed teaching ruler easily or be mobile, after protractor is overlapped with the angle of required measurement, pull-out expansion link, then rotate, can be used for angular surveying.The utlity model has the advantages such as simple in structure, practical and convenient.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is top view of the present utility model;
Fig. 2 is front view of the present utility model;
In figure: 1 chi body, 2 circular arc handles, 3 protractors, 4 expansion links, 5 air-bubble levels, 6 suckers.
The specific embodiment
embodiment 1:a kind of multifunctional teaching ruler, structure as shown in Figure 1-2: comprise chi body 1, the front of chi body 1 is provided with circular arc handle 2, and the inner side of circular arc handle 2 is provided with 4 depressions, and the height of circular arc handle 2 is 10 centimetres; The middle part of chi body 1 is provided with the protractor 3 with scale, and the center, base of protractor 3 is provided with expansion link 4.
The reverse side of chi body 1 is provided with 3 suckers, and sucker is positioned at 3 ends at the chi body back side; The front of chi body 1 is also provided with air-bubble level 5.When use, rely on air-bubble level 5 to determine level, then firmly press circular arc handle 2, the air in sucker 6 is just extruded, and chi body 1 can be fixed on the surface of object, then maps; Need to carry out angular surveying time, one side of protractor 3 is overlapped with one side of measured angle, the central point of protractor 3 overlaps with the end points of measured angle, and pull-out expansion link 4, then rotates, and just can carry out angular surveying.
embodiment 2:a kind of multifunctional teaching ruler, structure still as shown in Figure 1-2, as different from Example 1: the inner side of circular arc handle is provided with 3 depressions.
