Description
Technical field
The utility model relates to a kind of teaching aid, is specifically related to a kind of combined type mathematics appliance.
Background technology
Teaching aid is that being sci-tech mass media completely, is indispensable equipment in teenager's scientific and technological activities by the material object propagated for the purpose of science and technology, education people.Particularly abstract knowledge use teaching aid can be knowledge image, specialize, animation.
The application of mathematics teaching aid in teaching process is more widely, in mathematics classroom, teacher is when professor's course, need to draw a large amount of figures to explain to student, such teacher is at school in process, graphing is to teaching classroom time decreased, student needs to wait for that teacher learns after drawing, waste time in classroom, and increase the weight of the writing time of teacher, especially in mathematical education process, usually can use set square teaching aid, compass teaching aid and protractor teaching aid etc., these teaching aid individualisms existing, relatively dispersion, need when teacher maps to change back and forth, waste valuable instructional blocks of time, and considerably increase the workload of teacher.
Therefore, produce a kind of structure simply, reasonable in design, easy to operate, facilitate teacher to map, save time in classroom, effectively improve the combined type mathematics appliance of mathematical studying effect, there are market outlook widely.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of structure simple, reasonable in design, easy to operate, facilitates teacher to map, and saves time in classroom, effectively improves the combined type mathematics appliance of mathematical studying effect.
The technical solution of the utility model is achieved in that a kind of combined type mathematics appliance, comprise: ruler and Angle protractor, it is characterized in that: described ruler is provided with revolving part, revolving part is connected with triangle montant and rotation amount angular pole, the chi face of ruler is provided with slideway, slideway is provided with triangle brace, slideway two ends are provided with and buckle, triangle montant is provided with slip buckle, described Angle protractor is Foldable type Angle protractor, and the movable place of Angle protractor is provided with snap close.
Described Angle protractor is 360 degree of annulars, is provided with angle index.
Described ruler, rotation amount angular pole, triangle montant and triangle brace are provided with size scale.
Described triangle brace is scalable triangle brace.
The utility model has following good effect: the utility model provides a kind of combined type mathematics appliance, comprise: ruler and Angle protractor, ruler is provided with revolving part, revolving part is connected with triangle montant and rotation amount angular pole, the chi face of ruler is provided with slideway, slideway is provided with triangle brace, slideway two ends are provided with and buckle, triangle montant is provided with slip buckle, when using set square, the slip being buckled in triangle montant after being rotated by triangle brace buckles, Angle protractor is Foldable type Angle protractor, the movable place of Angle protractor is provided with snap close, use during ruler and Foldable type Angle protractor is folded up, whole ruler scale interfaces is spilt when ruler uses, during use amount gusset, the buckling on ruler by triangle montant and triangle brace kayser, open Foldable type Angle protractor, regulate rotation amount angular pole, therefore, this novel structure is simple, reasonable in design, easy to operate, teacher is facilitated to map, save time in classroom, effective raising mathematical studying effect.
Accompanying drawing explanation
Fig. 1 is the utility model full open position structural representation.
Fig. 2 is set square using state structural representation of the present utility model.
Fig. 3 is ruler using state structural representation of the present utility model.
In figure: 1, ruler 2, Angle protractor 3, rotation amount angular pole 4, slideway 5, triangle montant 6, triangle brace 7, buckle 8, slide buckle 9, revolving part.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of combined type mathematics appliance, comprise: ruler 1 and Angle protractor 2, described ruler 1 is provided with revolving part 9, revolving part 9 is connected with triangle montant 5 and rotation amount angular pole 3, the chi face of ruler 1 is provided with slideway 4, slideway 4 is provided with triangle brace 6, slideway 4 two ends is provided with and buckles 7, triangle montant 5 is provided with slip and buckles 8, described Angle protractor 2 is Foldable type Angle protractor, and the movable place of Angle protractor 2 is provided with snap close.Described Angle protractor 2 is 360 degree of annulars, is provided with angle index.Described ruler 1, rotation amount angular pole 3, triangle montant 5 and triangle brace 6 are provided with size scale.Described triangle brace 6 is scalable triangle brace.
The utility model in use, when using set square, the slip being buckled in triangle montant 5 after being rotated by triangle brace 6 buckles on 8, Angle protractor 2 is Foldable type Angle protractor, the movable place of Angle protractor 2 is provided with snap close, use during ruler 1 and Foldable type Angle protractor is folded up, the scale interface of whole rulers 1 is spilt when ruler 1 uses, during use amount gusset 2, triangle montant 5 and triangle brace 6 kayser are buckled on 7 on ruler, open Foldable type Angle protractor, and adopt the movable place of Angle protractor 2 to be provided with snap close fixed amount gusset 2, can take measurement of an angle, draw the angle of different angles as required to regulate rotation amount angular pole 3, this novel structure is simple, reasonable in design, easy to operate, teacher is facilitated to map, save time in classroom, effective raising mathematical studying effect.
