Abstract
The utility model relates to a combined teaching tool which comprises a plurality of ball bodies and connecting rods, wherein a plurality of holes are uniformly distributed on the surface of each ball body, the diameter of each hole is slightly smaller than that of each connecting rod, and each hole has the shrink range that the connecting rod can be conveniently inserted into the hole and hardly falls off from the hole; the connecting rods are respectively inserted into the ball bodies so that the ball bodies and the connecting rods are constructed into a frame structure to be demonstrated; when the combined teaching tool is used for demonstrating a molecular structure, the connecting rods can represent chemical bonds among molecules, and the ball bodies can represent atoms; when the combined teaching tool is used for demonstrating microscopic structures of other substances, the connecting rods only demonstrate special positions of various substance particles without representing any substance. The combined teaching tool can be assembled into microscopic structure models of different substances, so that the multi-hole balls and the connecting rods have multiple functions; in addition, the combined teaching tool is portable and saves the cost.
Description
Technical field
The utility model patent relates to a kind of teaching aid, particularly is applicable to the combined appliance for teaching that is used for connected mode between each particulate of micromechanism is carried out teaching demonstration.
Background technology
Relate in the course teaching of material microstructure at all types, Fu Za molecular structure is especially usually showed or demonstration and be difficult to accomplish that vivid giving lessons, student also are difficult to grasp relevant knowledge in default of model.As the layer aluminosilicate mineral are the main secondary minerals that relate in the pedology, and its structure and character are the important contents of courses of pedology, but the student runs into the molecular structure of complexity like this and be difficult to learn and to understand once entering this subject; In order to allow student's easy to understand, the teacher who has adopts bonding one-tenth simple models such as the spitball of table tennis, different color or chalk grain, cooperates planar graph to impart knowledge to students.The weak point of original this class teaching aid model: the one, the Self-made Realia model is bonding insecurely to scatter easily; The 2nd, the Self-made Realia model cements has consolidated that just can only to be used for a kind of model construction not portable, and once class says what models will be the micromechanism of what molecules will be with.
The utility model content
The purpose of this utility model provides a kind of spheroid that has a porous and connecting rod is formed, and is convenient to dismantle, assemble, and can be used for the teaching aid of the teaching demonstration that connects between each particulate of multiple molecular structure, to solve the deficiencies in the prior art.
The purpose of this utility model is achieved in that a kind of combined appliance for teaching, comprise a plurality of spheroids and connecting rod, spheroid is made by the material (as plastics) of lightweight flexible, spherome surface is evenly distributed with a plurality of holes, the diameter in hole is slightly less than the connecting rod diameter, and the magnitude of interference can make things convenient in the patchhole again difficult drop-off to be advisable with connecting rod.
During use, connecting rod is inserted spheroid, make the framed structure that spheroid and connecting rod are built into to be needed.When being used to demonstrate molecular structure, spheroid can be represented atom, and connecting rod is represented intermolecular chemical bond: when being used to demonstrate other material microstructures, but spheroid representative species particle, connecting rod is only demonstrated the locus of each material grains, does not represent any material.By different connected modes, can constitute different molecule demonstrating models or other particulate structure demonstrating models.
As preferably, spheroid can have diameter and the different colours that varies in size, and to represent particulate different in the molecule (atom, ion etc.), connecting rod can adopt different length and color.
By implementing the utility model, can arbitraryly be assembled into the microstructure models of different material, porous ball and connecting rod can be accomplished one-object-many-purposes, are easy to carry, and save cost.
The utility model is further described by embodiment below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a kind of user mode figure of the present utility model;
Fig. 3 is another kind of user mode figure of the present utility model.
1 is spheroid among Fig. 1, the 2nd, and hole, the 3rd, connecting rod.
Embodiment
Embodiment 1
A kind of combined appliance for teaching, comprise a plurality of spheroids 1 and connecting rod 3, spheroid 1 is made by the material (as plastics) of lightweight flexible, and spheroid 1 surface is evenly distributed with a plurality of holes 2, the diameter in hole 2 is slightly less than connecting rod 3 diameters, the magnitude of interference with connecting rod 3 can make things convenient for patchhole 2 again difficult drop-off be advisable.
During use, hole 2 with connecting rod 3 insertion spheroids, make the framed structure that spheroid 1 and connecting rod 3 are built into to be needed, when being used to demonstrate molecular structure, spheroid 1 can be represented atom, the intermolecular chemical bond of connecting rod 3 representatives, when being used to demonstrate other material microstructures, but spheroid 1 representative species particle, any material is not represented in the locus of each material grains of 3 demonstrations of connecting rod.By different connected modes, can constitute different molecule demonstrating models or other particulate structure demonstrating models.
As preferably, spheroid 1 can have diameter and the different colours that varies in size, and to represent particulate different in the molecule (atom, ion etc.), connecting rod 3 can adopt different length and color.
Claims (1)
1, a kind of combined appliance for teaching, comprise a plurality of spheroids and connecting rod, it is characterized in that: spherome surface is evenly distributed with a plurality of holes, the diameter in hole is slightly less than the connecting rod diameter, the magnitude of interference can make things convenient in the patchhole again difficult drop-off to be advisable with connecting rod, connecting rod is inserted spheroid, make the framed structure that spheroid and connecting rod are built into needs demonstration.
