Description

Technical Field

[0001] This utility model relates to the field of solid geometry simulation and demonstration technology, and in particular to a polyhedral assembly simulation structure for solid geometry demonstration. Background Technology

[0002] Solid geometry is a branch of mathematics. It is the traditional name for geometry in three-dimensional Euclidean space. Solid geometry generally includes cubes, cuboids, cylinders, cones, spheres, prisms, etc. Understanding these spatial concepts of solid geometry in advance can not only enhance the development of children's brains but also increase their spatial perception ability.

[0003] However, in the process of young children learning to understand solid geometry, in most cases, they learn through drawing or pictures, or through building with geometric blocks.

[0004] In solid geometry learning, it is often necessary to demonstrate using points, lines, and planes. However, since young children cannot naturally understand these forms simply by playing with them, most existing solid geometry demonstration and assembly structures are simulated structures that require plugging and connecting.

[0005] However, these existing solid geometry simulations are cumbersome to assemble and disassemble. Solid geometry emphasizes analysis, so it's often necessary to disassemble solid geometry during play and learning. Sometimes, even a complete solid geometry isn't needed, making the disassembly of solid geometry crucial. The existing solid geometry assembly structure makes it necessary to deform solid geometry, especially cubes and cuboids, to disassemble them. This is because the dimensions of solid geometry are symmetrical. When the last edge is inserted or disassembled, the solid geometry needs to be deformed, which can cause other solid geometry to decompose or break. Furthermore, if the solid geometry is flexible, it will deform after prolonged use, reducing the effectiveness of the simulation.

[0006] Therefore, this application requires the design of a polyhedral assembly simulation structure for solid geometry demonstration in order to solve the above-mentioned technical problems. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a polyhedron assembly simulation structure for solid geometry demonstrations. By using a connecting axis, children can easily and freely connect the connecting plates to achieve polyhedron assembly simulation. The fixed magnetic ball allows for convenient and quick installation and fixation of the sharp corners between the polyhedra, facilitating installation and fixation. Furthermore, it allows for the creation of any desired polyhedron frame without using connecting plates, improving overall expandability and increasing the freedom of assembly.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A polyhedral assembly simulation structure for solid geometry demonstration includes connecting plates, connecting shafts, and fixed magnetic balls. Multiple connecting plates are assembled along their edges to form a polyhedron. Each connecting plate is a polygonal planar plate with equal outer edge lengths. Each edge of a connecting plate has a connecting lug, which is integral with the connecting plate. The connecting lugs are positioned on the left side of the connecting plate's edge, with the vertical centerline of the edge as a reference. The edges of several assembled connecting plates are connected by connecting lugs, and two connecting lugs are connected by a connecting shaft. Fixed magnetic balls are located at the sharp corners of the assembled connecting plates, and these fixed magnetic balls are magnetically connected to the ends of several opposing connecting shafts.

[0010] By adopting the above technical solution: the connecting shaft allows children to easily connect the connecting plates to simulate the assembly of polyhedra, while the fixed magnetic ball allows for convenient and quick installation and fixation of the sharp corners between the polyhedra. This facilitates installation and fixation, and also allows for the creation of any polyhedral frame without using the connecting plates, improving overall expandability and increasing the freedom of assembly.

[0011] Preferably, the connecting plate is made of rigid sheet material, and both the upper and lower surfaces of the connecting plate are flush with the outer edge of the connecting lug. Each sharp corner of the connecting plate is flush with the end face of a connecting lug.

[0012] By adopting the above technical solution, the rigid board connecting plate allows for the free use of connecting plates with different numbers of sides to create polyhedra with different numbers of faces, thus achieving a quick, convenient, and free assembly experience, which can increase children's interest in the process of using it.

[0013] Preferably, the connecting ear is a through-type cylindrical structure with a through-hole. The length of the connecting ear is half the length of the edge of the connecting plate. One end of the connecting ear is aligned with the sharp corner of the edge of the connecting plate, and the other end of the connecting ear is aligned with the center of the edge of the connecting plate.

[0014] By adopting the above technical solution, the connecting lugs with a length of half the edge allow for arbitrary splicing and assembly of the connecting plates, improving the installation effect of the connecting plates and facilitating arbitrary installation of the connecting plates on polyhedra.

[0015] Preferably, the connecting shaft is cylindrical in shape, the outer diameter of the connecting shaft is the same as the inner diameter of the connecting lug, the connecting shaft can be inserted into the shaft hole of the connecting lug, and both ends of the connecting shaft are provided with receiving magnetic ends.

[0016] By adopting the above technical solution, magnetic receiving ends are set at both ends of the connecting shaft, which is traditionally only used for round shaft pin connection. This achieves the fixation of the connecting shaft ends, and the magnetic properties also facilitate disassembly and assembly, increasing the possibility of splicing.

[0017] Preferably, the fixed magnetic ball is made of a magnetically emitting metal ball, and the diameter of the fixed magnetic ball is less than twice the diameter of the connecting shaft.

[0018] By adopting the above technical solution, the fixed magnetic ball not only fixes the sharp corners of the polyhedron to prevent the connecting plate from loosening, but also allows for a visual representation of how many corners a polyhedron has during assembly, thus facilitating a more comprehensive understanding of solid geometry.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model allows children to easily connect connecting plates by using a connecting shaft, enabling demonstration and assembly simulation of polyhedra. The fixed magnetic ball allows for convenient and quick installation and fixation of the sharp corners between polyhedra, facilitating installation and fixation. Furthermore, it allows for the creation of any polyhedral frame without using connecting plates, improving overall expandability and increasing the freedom of assembly.

[0021] 2. This utility model uses a rigid board connecting plate, which allows for the free use of connecting plates with different numbers of sides to create polyhedra with different numbers of faces, thereby achieving a quick, convenient, and free assembly experience, which can increase children's interest in using it.

[0022] 3. This utility model, through the connecting lug with an edge length of half, enables arbitrary splicing and assembly of connecting plates, thereby improving the installation effect of the connecting plates and facilitating the arbitrary installation of the connecting plates on polyhedra.

[0023] 4. This utility model achieves fixed ends of the connecting shaft by setting magnetic receiving ends at both ends of the connecting shaft, which is traditionally only used for round shaft pin connection. Furthermore, the magnetic property facilitates disassembly and assembly, increasing the possibility of splicing.

[0024] 5. This utility model, by fixing magnetic balls, can not only fix the sharp corners of the polyhedron to prevent the connecting plate from loosening, but also intuitively show how many corners a polyhedron has during the assembly process, thus making it easier to learn solid geometry.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Reference Figures 1-6A polyhedral assembly simulation structure for solid geometry demonstration is disclosed. The polyhedral assembly simulation structure includes connecting plates 1, connecting shafts 2, and fixed magnetic balls 3. There are multiple connecting plates 1, which are assembled into a polyhedron by combining their edges. Each connecting plate 1 is a polygonal planar plate with equal outer edge lengths. Each edge of the connecting plate 1 is provided with a connecting lug 4, which is an integral part of the connecting plate 1. The connecting lugs 4 are all located on the left side of the edge of the connecting plate 1 with the vertical center line of the edge as the reference. The edges of several assembled connecting plates 1 are connected to each other by connecting lugs 4. Two connecting lugs 4 are connected by connecting shafts 2. Fixed magnetic balls 3 are provided at the sharp corners of several assembled connecting plates 1, and the fixed magnetic balls 3 are magnetically connected to the ends of several opposing connecting shafts 2.

[0034] In this embodiment, the use of a connecting shaft allows children to easily connect the connecting plates, enabling a demonstration and simulation of polyhedron assembly. The fixed magnetic ball allows for quick and easy installation and fixation of the sharp corners between the polyhedrons, facilitating installation and fixation. Furthermore, it allows for the creation of any polyhedron frame without the use of connecting plates, improving overall expandability and increasing the freedom of assembly.

[0035] Specifically, refer to Figure 5 The connecting plate 1 is made of rigid plate material. Both the upper and lower surfaces of the connecting plate 1 are flush with the outer edge of the connecting lug 4. Each sharp corner of the connecting plate 1 is flush with and connected to the end face of a connecting lug 4.

[0036] In this embodiment, the use of rigid board connecting plates allows for the free use of connecting plates with different numbers of sides to create polyhedra with different numbers of faces, thus achieving a quick, convenient, and free assembly experience and increasing children's interest in using the equipment.

[0037] Specifically, refer to Figure 5 The connecting lug 4 is shaped as a straight through arc cylinder. The connecting lug 4 has a through shaft hole 4-1 inside. The length of the connecting lug 4 is half the length of the edge of the connecting plate 1. One end of the connecting lug 4 is aligned with the sharp corner of the edge of the connecting plate 1, and the other end of the connecting lug 4 is aligned with the center of the edge of the connecting plate 1.

[0038] In this embodiment, the connecting lugs, which are half the length of the edge, allow for arbitrary splicing and assembly of the connecting plates, improving the installation effect of the connecting plates and facilitating their arbitrary installation on the polyhedron.

[0039] Specifically, refer to Figure 6The connecting shaft 2 is cylindrical in shape, and the outer diameter of the connecting shaft 2 is the same as the inner diameter of the connecting lug 4. The connecting shaft 2 can be inserted into the shaft hole 4-1 of the connecting lug 4, and both ends of the connecting shaft 2 are provided with receiving magnetic ends.

[0040] In this embodiment, by setting receiving magnetic ends at both ends of the connecting shaft, which is traditionally only used for round shaft pin connection, the endpoints of the connecting shaft are fixed. Furthermore, the magnetic properties facilitate disassembly and assembly, increasing the possibility of splicing.

[0041] Specifically, refer to Figure 6 The fixed magnetic ball 3 is made of a magnetically emitting metal ball, and the diameter of the fixed magnetic ball 3 is less than twice the diameter of the connecting shaft 2.

[0042] In this embodiment, the use of fixed magnetic balls not only secures the sharp corners of the polyhedron to prevent the connecting plate from loosening, but also visually demonstrates how many corners a polyhedron has during assembly, thus facilitating a more comprehensive understanding of solid geometry.

[0043] When this utility model is used for splicing, it uses connecting plates 1 with the same number of edges. Two connecting plates 1 are connected by connecting lugs 4 along the edges of the connecting plates 1 and then connected by connecting shafts 2. Several connecting plates 1 are then spliced ​​together in the same way to achieve the most intuitive polyhedral splicing. Furthermore, these connecting plates 1 are connected by connecting shafts 2 along their edges to achieve convenient and free board surface connection. Finally, the end faces of several opposing connecting shafts 2 are magnetically fixed by fixing magnetic balls 3. After the polyhedral splicing is completed, the overall connection strength of the polyhedral is ensured, and the number of sharp corners of the polyhedral can be seen intuitively.

[0044] Meanwhile, this utility model can also achieve the connection and splicing of polyhedrons by directly magnetically attaching the end face of the connecting shaft 2 to the outer surface of the fixed magnetic ball 3 in any form without using the connecting plate 1. It can also achieve the connection and splicing of polyhedrons even without the corresponding shape of the connecting plate 1.

[0045] In summary, this utility model allows children to easily connect the connecting plates by using a connecting shaft, enabling demonstration and assembly simulation of polyhedra. The fixed magnetic ball allows for convenient and quick installation and fixation of the sharp corners between polyhedra. Furthermore, it enables the creation of any desired polyhedral frame without using connecting plates, improving overall expandability and increasing the freedom of assembly.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
