Abstract
The utility model discloses a combined teaching appliance comprising a ruler and a protractor. The ruler is provided with a chute in the length direction, and the chute is provided with a chalk clamp capable of moving along the chute. The protractor is in a circular disc shape and is provided with angle numerical values in the range of 0 degree to 360 degrees. One end of the ruler is hinged with the circle center of the protractor by a hinge. The ruler and the protractor are made of transparent plastic. The utility model has simple structure and multiple functions; by the combined teaching appliance, straight lines, angles and circles are convenient to draw; in addition, the utility model is more convenient to carry, use and store.
Description
Technical field
The utility model relates to the teaching aid technical field, specifically, relates to a kind of combined teaching aid.
Background technology
The teaching aid that existing ruler, set square, protractor etc. have simple function all is math teacher teaching aid commonly used and indispensability in about teaching, all must carry simultaneously when entering the classroom, during use, the purposes different according to teaching aid, select to use, with after be placed on the lectern relatively occupation of land side.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of combined teaching aid at above-mentioned defective, have the function singleness that teaching aid exists now to solve, and carry, use and deposit inconvenient problem.
For solving the problems of the technologies described above, the technical solution of the utility model is: combined teaching aid, comprise ruler, and described ruler is provided with chute along its length direction, and described chute is provided with can be along its chalk that moves folder; Protractor, described protractor is disc, and described protractor is provided with 0 °～360 ° angle numerical value; One end of described ruler and the center of circle of described protractor are hinged by hinge.
As optimized technical scheme, described ruler and described protractor all adopt transparent plastic.
Owing to adopted technique scheme, compared with prior art, the beneficial effects of the utility model are:
Because described combined teaching aid comprises ruler, described ruler is provided with chute along its length direction, and described chute is provided with can be along its chalk that moves folder; Protractor, described protractor is disc, and described protractor is provided with 0 °～360 ° angle numerical value; One end of described ruler and the center of circle of described protractor are hinged by hinge.Described ruler has the function of common ruler, can be used to the picture straight line; When drawing angle, discoidal protractor is fixed, with baseline of ruler picture, allow ruler turn to needed angle numerical value place then earlier, directly with the chalk angle of can drawing around hinge; When needs picture bowlder, the chalk folder is moved to the desired location place along chute, with the hinge center of circle, be radius with chalk and the distance between the hinge on the chalk folder, rotating ruler is that available drawing with coloured chalk goes out needed circle.The utility model is simple in structure, diverse in function, and carry, use and deposit all more convenient.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: the 1-protractor; 11-angle numerical value; The 2-ruler; The 21-scale; 3-chalk folder; The 4-chute; The 5-hinge.
The specific embodiment
As shown in drawings, combined teaching aid comprises ruler 2, and described ruler 2 is provided with scale 21, and described ruler 2 is provided with chute 4 along its length direction, and described chute 4 is provided with can be along its chalk that moves folder 3; Protractor 1, described protractor 1 is disc, and described protractor 1 is provided with 0 °～360 ° angle numerical value 11; One end of described ruler 2 and the center of circle of described protractor 1 are hinged by hinge 5.
Wherein, described ruler 2 all adopts transparent plastic to make with described protractor 1.
The utility model in use, described ruler 2 has the function of common ruler, can be used to the picture straight line; When drawing angle, fixing discoidal protractor 1, with baseline of ruler 2 pictures, allow ruler 2 turn to needed angle numerical value place then earlier, directly with the chalk angle of can drawing around hinge 5; When needs picture bowlder, chalk folder 3 is moved to the desired location place along chute 4, be the center of circle with hinge 5, be radius with chalk and the distance between the hinge 5 on the chalk folder 3, rotating ruler 2 is that available drawing with coloured chalk goes out needed circle.The utility model is simple in structure, diverse in function, and carry, use and deposit all more convenient.
