Description
Technical field
The utility model relates to a kind of multifunctional teaching gauge.
Background technology
In middle school teaching practice, teacher is for the angle of various triangle and different angles, when carrying out ocular demonstration and writing on the blackboard, often need repeatedly to use ruler and compasses, this adds the workload of teacher virtually, waste valuable time in classroom, commercially also do not occur the relevant teaching gauge that structure is simple, easy to use at present.
Utility model content
The purpose of this utility model solves above-mentioned Problems existing, provides that a kind of structure is simple, easy to use, demonstration and the effective multifunctional teaching gauge of writing on the blackboard.
The utility model is achieved in that
Multifunctional teaching gauge, is made up of a protractor and two rulers, and described protractor is by the base as diameter and form in semi-annular shape angulation limit, is provided with the open type chute along the arrangement of semicircular ring direction between the two-end-point on semi-annular shape angulation limit; Two rulers are respectively equipped with the open type chute along ruler long side direction; Connect between two respectively by rotating shaft between each open type chute of the open type chute of protractor and two rulers.
The rotating shaft connecting the chute that first round chute of protractor, two rulers are arranged respectively between two of the present utility model, can slide in above-mentioned chute.In use, the utility model, by the slip of rotating shaft, drives two rulers to carry out relative motion on protractor, can demonstrate out the triangle that acute angle, right angle, obtuse angle etc. are dissimilar; Meanwhile, the semi-annular shape angulation limit of protractor, base and two rulers can be equipped with scale, to draw the angle of different angles; Protractor base or two rulers all can use as ruler, decrease teacher teach writing on the blackboard time frequent converted quantity hornwork and the amount of labour of ruler.Meanwhile, the semi-annular shape angulation limit of protractor as handle, can also be easy to teacher's demonstration.
It is simple that the utility model has structure, easy to use, good demonstration effect, be easy to make, lower-cost feature.
The utility model is described in further detail for connection with figures and embodiment below.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation
Detailed description of the invention
Embodiment 1
Composition graphs 1, multifunctional teaching gauge, be made up of a protractor 1 and ruler 3, ruler 5, described protractor 1 is by the base as diameter and form in semi-annular shape angulation limit, is provided with the open type chute 2 along the arrangement of semicircular ring direction between the two-end-point on semi-annular shape angulation limit; Ruler 3 and ruler 5 are respectively equipped with open type chute 4, the open type chute 6 along ruler long side direction; Connect between two respectively by rotating shaft 7, rotating shaft 8, rotating shaft 9 between the open type chute 2 of protractor and each open type chute 4 of two rulers, open type chute 5.
Connect the rotating shaft of protractor 1 and ruler 3, ruler 5 upper hopper chute in the utility model between two, can slide in above-mentioned respective chute.In use, the utility model, by the slip of rotating shaft, drives ruler 3 and ruler 5 to carry out relative motion on protractor 1, can demonstrate out the triangle that acute angle, right angle, obtuse angle etc. are dissimilar; Meanwhile, the semi-annular shape angulation limit of protractor 1 is provided with scale, to draw the angle of different angles; The base of protractor and ruler 3 and ruler 5 can be equipped with scale, to meet the object used as ruler, considerably reduce teacher teach writing on the blackboard time frequent converted quantity hornwork and the amount of labour of ruler.Meanwhile, the semi-annular shape angulation limit of protractor as handle, can also be easy to teacher's demonstration.
It is simple that the utility model has structure, easy to use, good demonstration effect, be easy to make, lower-cost advantage.
