Description

Technical Field

[0001] This application relates to the field of model combination teaching aids technology, and more specifically, to a solid geometry segmentation model combination teaching aid. Background Technology

[0002] Existing teaching aids based on similar solid geometry models also include nine basic geometric types, but they suffer from insurmountable technical problems. These basic models are all monolithic, lacking visual representation of internal geometric changes, and cannot be interlocked or combined. This limits the possibilities for unlimited design and restricts the ability of engineers to simulate and model using physical objects.

[0003] Therefore, a teaching aid combining solid geometry segmentation models is needed to solve the above problems. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section above, some embodiments of this application provide a three-dimensional geometric segmentation model combination teaching aid, including: a main body, multiple main bodies that can be detachably joined; a connector for connecting the main bodies; the main body has at least one mounting plane, the main body is a hollow body, at least one recess is provided on the mounting plane, and a gap is provided in the recess that extends into the inner cavity of the main body, and the connector is inserted into the gap for connection.

[0006] Furthermore, the connector includes: a limiting protrusion located at the middle position of the main body and the two ends of the main body being configured as insertion ends that are inserted into the gap.

[0007] Furthermore, the mounting surface has multiple recesses, which are distributed perpendicularly to each other, dividing the surface into multiple rectangular grids, with gaps located on the sides of the rectangular grids.

[0008] Furthermore, when the insertion end of the connector is inserted into the gap, the limiting protrusion is embedded in the recess.

[0009] Furthermore, the depth dimension of the indentation is the first dimension D, and the width dimension of the limiting protrusion is the second dimension D. The second dimension D is not greater than twice the first dimension D, so that when the two main bodies are spliced ​​together by the connector, the limiting protrusion is embedded in the indentation on the two main bodies, and the mounting planes of the two main bodies abut against each other.

[0010] Furthermore, the thickness dimension of the connector is the third dimension D, the width dimension of the indentation is the fourth dimension D, and the third dimension D and the fourth dimension D are adapted to each other; the width dimension of the insertion end is the fifth dimension D, the width dimension of the gap is the sixth dimension D, and the fifth dimension D and the sixth dimension D are adapted to each other.

[0011] Furthermore, all planes and connectors of the main body are made of nylon plastic.

[0012] The beneficial effects of this application are as follows:

[0013] 1. By setting at least one mounting plane on the main body, when splicing two main bodies, the two mounting planes are opposite each other. By splicing main bodies of different shapes, different model structures are finally formed, and the main body structure contained in the different model structures can be observed.

[0014] 2. With the connectors provided, when the main bodies are spliced ​​together, the connectors are inserted into the corresponding mounting planes of the main bodies, and after the splicing is completed, the connectors will not be exposed, thus improving the overall integrity of the spliced ​​model.

[0041] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] Reference Figure 1-5 A three-dimensional geometric segmentation model assembly teaching aid includes a main body 10 and connecting members 12. Multiple main bodies 10 are detachably joined to form a model. Each main body 10 has a fixed surface and at least one mounting surface 11, which together with the fixed surface form a hollow body. At least one recess 15 is provided on at least one surface, and a gap 16 extending into the inner cavity of the main body 10 is provided within the recess 15. The connecting member 12 is inserted into the gap 16 for connection.

[0043] The connector 12 includes a limiting protrusion 14 positioned between the two main bodies 10, and insertion ends 17 at both ends of the main bodies 10 that are inserted into the insertion gaps 16. When two main bodies 10 need to be joined together, the mounting surfaces 11 of the two main bodies 10 are facing each other. One insertion end 17 of the connector 12 is inserted into the recess 15 and gap 16 of the mounting surface 11 of one main body 10, and the recess 15 and gap 16 of the mounting surface 11 of the other main body 10 are aligned with the other insertion end 17 for joining.

[0044] Multiple recesses 15 are provided on the mounting surface 11. The multiple recesses 15 are distributed perpendicularly to each other, dividing the surface into multiple rectangular grids. The gaps 16 are set on the side of the rectangular grids to improve the flexibility of splicing.

[0045] When the insertion end 17 of the connector 12 is inserted into the gap 16, the limiting protrusion 14 is embedded in the recess 15 and the limiting protrusion 14 abuts against the bottom of the recess 15, preventing the connector 12 from entering the gap 16 completely, so that only one end of the insertion end 17 is inserted into the gap 16.

[0046] The depth of the indentation 15 is a first dimension D1, and the width of the limiting protrusion 14 is a second dimension D2. The second dimension D2 is not greater than twice the first dimension D1, so that when the two main bodies 10 are spliced ​​together by the connector 12, the limiting protrusion 14 is embedded in the indentation 15 on the two main bodies 10, and the opposite mounting surfaces 11 of the two main bodies 10 abut against each other. When the two main bodies 10 are spliced ​​together, the mounting surfaces 11 of the two main bodies 10 are opposite each other. Since the second dimension D2 is not greater than twice the first dimension D1, the mounting surfaces 11 of the two main bodies 10 can fit together, ensuring a complete splice and avoiding gaps.

[0047] The thickness dimension of connector 12 is the third dimension D3, and the width dimension of recess 15 is the fourth dimension D4. The third dimension D3 and the fourth dimension D4 are compatible.

[0048] The width dimension of the insertion end 17 is the fifth dimension D5, and the width dimension of the gap 16 is the sixth dimension D6. The fifth dimension D5 and the sixth dimension D6 are adapted to each other. The head end of the insertion end 17 is machined to form a chamfer for easy insertion.

[0049] The main body 10 and the connecting parts 12 are made of plastic.

[0050] like Figure 1 As shown, in one embodiment, the main body 10 is a cubic structure with six mounting planes 11 and recesses 15 distributed on the six mounting planes 11, dividing the planes into multiple rectangular grids.

[0051] like Figure 6 As shown, in one embodiment, the main body 10 is configured as a partial sphere, formed by splicing multiple main bodies 10. Specifically, with the center of the sphere as the center, it is divided into two hollow hemispheres along the latitude lines. Then, it is divided into four equal parts along the meridian lines; the entire globe is divided into eight main bodies 10.

[0052] like Figure 7 As shown, in one embodiment, the main body 10 is set as a partial cone, and four main bodies 10 are spliced ​​together to form a cone model.

[0053] like Figure 8 As shown, in one embodiment, the main body 10 is set as a partial frustum, and four main bodies 10 are spliced ​​together to form a frustum model.

[0054] like Figure 9As shown, in one embodiment, the main body 10 is set as a partial cylinder, and four main bodies 10 are spliced ​​together to form a cylindrical model.

[0055] like Figures 10-17 In other embodiments, the main body 10 has different structures. Different shapes of models are formed by splicing together the main bodies 10 with different structures.

[0056] Working process or usage method:

[0057] When two main bodies 10 need to be spliced ​​together, the mounting surfaces 11 of the two main bodies 10 are facing each other. One insertion end 17 of the connector 12 is inserted into the recess 15 and gap 16 of the mounting surface 11 of one main body 10. The recess 15 and gap 16 of the mounting surface 11 of the other main body 10 are aligned with the other insertion end 17 for splicing. At this time, the limiting protrusion 14 limits the connector 12, ensuring that the insertion ends 17 at both ends of the connector 12 are inserted into the gaps 16 of the mounting surfaces 11 of the two main bodies 10 respectively. Since the second dimension D2 is not greater than twice the first dimension D1, the mounting surfaces 11 of the two main bodies 10 can fit together to ensure complete splicing and avoid gaps.
