Columnar structure capable of splicing plates and teaching aid for connecting columnar structures using plates

Abstract

A columnar structure with connectable panels includes a column and at least two connecting portions. The column is polygonal and has a plurality of sides. The connecting portions are respectively disposed on at least two of the sides of the column and their length direction is parallel to the length direction of the column. Each connecting portion includes two protrusions, and a groove is formed between the protrusions for one side of a panel to be disposed therein. Thus, the columnar structure can be assembled with panels via the connecting portions to form a set of teaching aids.

Claims

1. A columnar structure with connectable panels, comprising: A column, which is polygonal and has a plurality of sides; and at least two connecting portions, which are respectively disposed on at least two of the sides of the column and whose length direction is parallel to the length direction of the column, each connecting portion including two protrusions, and forming a groove between the protrusions for a plate to be disposed therein.

2. The columnar structure of the splicable panels as described in claim 1, wherein, The lengths of the grooves in these connecting parts are equal.

3. The columnar structure of the splicable panels as described in claim 1, wherein, The widths of the grooves in these connecting parts are equal.

4. The columnar structure of the splicable panels as described in claim 1, wherein, The depths of the grooves in these connecting parts are equal.

5. The columnar structure of the splicable panels as described in claim 1, wherein, These connecting parts are all the same size.

6. The columnar structure of the splicable panels as described in claim 1, wherein, The length of the column is equal to the length of the connecting parts.

7. The columnar structure of the connectable panels as described in claim 1, wherein, There are multiple such connecting parts, and these connecting parts are respectively provided on such sides of the column.

8. A teaching aid that utilizes a plate to connect a columnar structure, comprising: A plurality of columnar structures of connectable panels, each columnar structure including a column and at least two connecting portions, the column being polygonal and having a plurality of side surfaces, the connecting portions being respectively disposed on at least two of the side surfaces of the column and having their length direction parallel to the length direction of the column, each connecting portion including two protrusions forming a groove between the protrusions; and a plurality of panels, the two sides of which are respectively disposed in the grooves of the connecting portions of the columnar structures.
