Abstract
The utility model discloses a three-dimensional geometrical special-purpose teaching aid comprising twelve pillars. The twelve pillars are mutually connected to form a cube-shaped framework. Each surface of each pillar is provided with a connection aperture. The three-dimensional geometrical special-purpose teaching aid also comprises rubber cords. The both ends of each rubber cord are provided with hooks. The hooks are connected with the connection apertures. The lower surface of the framework is provided with a pedestal. An accommodating groove is arranged in a side surface of the pedestal. A side surface, which is adjacent to a drawer, is provided with a writing plate. The writing plate is in slidable connection with the pedestal. The four angles of the lower surface of the pedestal are all provided with support columns. The support columns are of a telescopic sleeve tube structure. The lower surfaces of the support columns are provided with rubber gaskets. According to the three-dimensional geometrical special-purpose teaching aid of the utility model, explanation of three-dimensional geometry can be carried out conveniently, visually, and vividly, and the three-dimensional geometrical special-purpose teaching aid is beneficially for raising the interests of students.
Description
Technical field
The utility model belongs to the teaching aid field, is specifically related to a kind of solid geometry demonstration teaching aid special.
Background technology
In present several teaching, more and more higher for the requirement of space imagination.And at present, the teacher is generally by blackboard drawing when teaching, then impart knowledge to students by the mode of explanation.This mode is too dull, and the student is difficult to obtain three-dimensional understanding.In the course of time, the student also likely produces weary mood.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of solid geometry demonstration teaching aid special is provided, and can explain easily solid geometry, vivid, contributes to improve student's interest.
The technical scheme that the utility model adopts is: a kind of solid geometry demonstration teaching aid special, comprise 12 pillars, described 12 pillars are interconnected to form square bodily form framework, all have connecting hole on each face of every pillar, also comprise bungee, described bungee two ends are equipped with hook, hook is connected with connecting hole, described framework lower surface is provided with base, a base wherein side has article putting groove, the wherein side that base and drawer are adjacent is provided with clipboard, described clipboard is connected with base sliding, base lower surface is equipped with support column on four angles, described support column is telescopic sleeve structure, the support column lower surface is provided with rubber blanket.
As preferably, described support column and base removably connect.
As preferably, the mode that removably connects between described support column and base is for being threaded.
The beneficial effects of the utility model are: connecting hole coordinates upper bungee and hook, in the framework that can easily form at 12 pillars, forms various solid figures.Can place some simple instruments in article putting groove.Clipboard can be write easily.Support column is scalable, can regulate height according to actual conditions.Rubber blanket is damping to a certain extent.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, pillar; 2, connecting hole; 3, bungee; 4, base; 5, article putting groove; 6, clipboard; 7, support column; 8, rubber blanket.
Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of solid geometry demonstration teaching aid special, comprise 12 pillars 1, described 12 pillars 1 are interconnected to form square bodily form framework, all have connecting hole 2 on each face of every pillar 1, also comprise bungee 3, described bungee 3 two ends are equipped with hook, hook is connected with connecting hole 2, described framework lower surface is provided with base 4, base 4 a wherein side has article putting groove 5, the wherein side that base 4 is adjacent with drawer is provided with clipboard 6, described clipboard 6 is slidably connected with base 4, base 4 lower surface is equipped with support column 7 on four angles, described support column 7 is telescopic sleeve structure, support column 7 lower surfaces are provided with rubber blanket 8.As preferably, described support column 7 removably connects with base 4.As preferably, the mode that removably connects of described support column 7 and 4 of bases is for being threaded.
During use, the hook that is connected to bungee 3 two ends is hung in connecting hole 2, so just can be formed easily solid geometry figure.Support column 7 is scalable, can regulate height according to actual conditions.
