Abstract
The utility model provides a math plotter which comprises a main scale and an auxiliary scale. The end of the main scale and the end of the auxiliary scale are connected through a first hinge, a first cavity for accommodating the auxiliary scale is positioned on the main scale, and compasses and an angle gauge which are capable of turning around the edge of the auxiliary scale. The math plotter is simple in structure, ingenious in design, small in size, convenient to carry and suitable for being popularized.
Description
Technical field
The utility model relates to the teaching equipment field, especially relates to a kind of mathematics plotter.
Background technology
Existing mathematics plotter, comprise main scale and complementary scale, main scale and complementary scale one end are hinged by hinge, and the other end is respectively arranged with graphometer, offer one on complementary scale along the straight runner of complementary scale long limit extension, be equipped with on straight runner for the tuning knob of regulating radius of circle.The plotter of this structure, complex structure, floor space is large, complicated operation.
Summary of the invention
The purpose of this utility model is to provide a kind of mathematics plotter, can solve present plotter, complex structure, and floor space is large, the problem of complicated operation.
Technical scheme provided by the utility model is: a kind of mathematics plotter, comprise main scale and complementary scale, the end of main scale afterbody and complementary scale is by a chain connection, main scale is provided be used to a cavity that holds complementary scale, and complementary scale is provided with can be around compasses and the protractor of complementary scale edge upset.
According to the technical solution of the utility model, compasses and protractor fix on respectively the edge of complementary scale by No. two hinges fixing.
The beneficial effects of the utility model are:
The utility model is simple in structure, designs ingeniously, and volume is little, and being easy to carry is a kind of new design, is suitable for promoting.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
A kind of mathematics plotter as shown in Figure 1, comprise main scale 1 and complementary scale 2, main scale 1 afterbody is connected by a hinge 3 with the end of complementary scale 2, main scale 1 is provided be used to a cavity 4 that holds complementary scale 2, and complementary scale 2 is provided with can be around compasses 5 and the protractor of complementary scale 2 edge upsets.
Namely can be connected by hinge 3 as mentioned above between main scale 1 and complementary scale 2, also can connect by chute, that is, in cavity 4 both sides of main scale, slideway is set, the edge of complementary scale 2 can slip into cavity 4 No. one along slideway.Compasses 5 and protractor 6 are fixed on respectively the edge of complementary scale 2 by No. two hinges 7, compasses 5, protractor 6 also can be connected with complementary scale by clip, namely be provided with the fixing clip of an end at the complementary scale edge, by clip fixedly compasses and protractor, so in use, compasses and protractor are taken off, when not using, it is clipped on complementary scale, avoid losing.
The utility model is simple in structure, designs ingeniously, and volume is little, and being easy to carry is a kind of new design, is suitable for promoting.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
