Description
Technical field
The utility model belongs to teaching aid field, particularly a kind of round platform teaching aid.
Background technology
Round platform and cylinder are the conventional teaching aids in mathematical education, because the two shape is different, need to carry different teaching aid time at school simultaneously, very inconvenient.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of round platform teaching aid, round platform can be combined with cylinder, be convenient for carrying.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of round platform teaching aid, comprise round platform 1 and hollow block 2, the outside of described hollow block 2 is cylindric, the bottom surface equal diameters of diameter of section and round platform 1, and the hollow part of hollow block 2 is consistent with the outer contour shape of round platform 1.
Telescopic right cylinder 3 is had, the diameter of section of right cylinder 3 and the bottom surface equal diameters of round platform 1 above the hollow part of described hollow block 2.
The side lower of described round platform 1 is provided with external thread, and the hollow part inwall of described hollow block 2 is provided with the internal thread mated with described external thread.
The outer wall of described right cylinder 3 is provided with scale mark.
Described right cylinder 3 is hollow-core construction.
The bottom surface of described round platform 1 is slotted and be provided with lateral shaft in groove, and handle is rotatably connected on round platform 1 by horizontal rotating shaft.
Compared with prior art, round platform is hidden among cylinder by the utility model, and the two is combined as a whole, and partition is convenient, is easy to carry in teaching, can also change the height of cylinder simultaneously, and can place other teaching article such as chalk, ruler in cylinder.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model round platform schematic diagram.
Fig. 3 is the hollow block schematic diagram of the utility model.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of round platform teaching aid, comprises round platform 1 and hollow block 2, the outside of hollow block 2 is cylindric, the bottom surface equal diameters of diameter of section and round platform 1, the hollow part of hollow block 2 is consistent with the outer contour shape of round platform 1, round platform 1 can be mounted in it.
