Description

Technical Field

[0001] The utility model belongs to the technical field of high school mathematics teaching, in particular to a three-view teaching demonstration structure for high school. Background Art

[0002] In high school mathematics, the concept of three-view drawing is a key concept in geometry. It involves the main view, top view, and side view of an object. Understanding and mastering the three-view drawing is crucial for students to develop spatial imagination and solve practical problems.

[0003] However, traditional teaching methods often use flat drawings or two-dimensional graphics to explain the projection of three-dimensional objects. This approach often makes it difficult for students to intuitively understand the spatial relationships of objects. Static teaching materials such as books and blackboard drawings do not allow students to actively participate in the learning process. Students can only passively receive information and lack opportunities for hands-on practice, which affects their learning interest and effectiveness. Utility Model Content

[0004] The purpose of the utility model is to provide a three-view teaching demonstration structure for high schools to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a three-view teaching demonstration structure for high school students, comprising:

[0006] A three-view demonstration assembly for use in high school three-view chapter teaching demonstrations, the three-view demonstration assembly including a demonstration support plate;

[0007] A demonstration turntable is rotatably mounted on the top surface of the demonstration support plate;

[0008] A three-view demonstration frame assembly is disposed on the top surface of the demonstration turntable, and one end of the bottom of the three-view demonstration frame assembly is hinged to the top surface of the demonstration turntable for flipping the three-view demonstration frame assembly;

[0009] Among them, the three-view demonstration frame assembly includes a demonstration transparent bottom plate with one end hinged to the top surface of the demonstration turntable, a demonstration transparent frame plate fixed to the top surface of the demonstration transparent bottom plate, and a demonstration transparent top cover detachably installed on the top surface of the demonstration transparent frame plate. The shape to be demonstrated is set up by a support assembly at the middle position of the top surface of the demonstration transparent bottom plate, and the demonstration transparent frame plate encloses the shape to be demonstrated, so that views of the shape to be demonstrated in different orientations can be demonstrated from any direction around the demonstration transparent frame plate, from the top surface of the demonstration transparent top cover, and by flipping the demonstration transparent bottom plate.

[0010] Preferably, a hinged flip groove is provided on the peripheral edge of the top surface of the demonstration turntable, and hinged ear plates are fixed on both sides of the hinged flip groove and on the top surface of the demonstration turntable.

[0011] Preferably, pins are fixed to the outer walls on both sides of one end of the demonstration transparent bottom plate, and the two pins are respectively connected to the two hinged ear blocks, so that the hinged end of the demonstration transparent bottom plate protrudes above the hinged flip groove, so that when the demonstration transparent bottom plate is flipped, the hinged end of the demonstration transparent bottom plate can flip in the hinged flip groove.

[0012] Preferably, a bearing is embedded in the middle of the top surface of the demonstration support plate, the inner ring of the bearing is interference-fitted with a rotating shaft, and the top end of the rotating shaft is fixedly connected to the center of the bottom surface of the demonstration turntable.

[0013] In this solution, a plurality of latch holes are symmetrically provided on the top surface of the demonstration transparent frame plate, and a plurality of latch columns are symmetrically connected to the edge side of the bottom surface of the demonstration transparent top cover.

[0014] Preferably, in this solution, when the clamping column is adapted to be inserted into the clamping hole, the demonstration transparent top cover covers the top surface of the demonstration transparent frame plate.

[0015] Preferably, the support assembly includes a transparent column fixed to the middle position of the top surface of the demonstration transparent bottom plate, and a transparent support plate fixed to the top of the transparent column.

[0017] Preferably, the bottom surface of the demonstration transparent bottom plate, the peripheral outer wall of the demonstration transparent frame plate and the corner of one side of the top surface of the demonstration transparent top cover are all provided with marking labels for marking different views.

[0018] Preferably, handles are fixed to the outer walls on both sides of the demonstration support plate.

[0019] Compared with the prior art, the technical effects and advantages of this utility model are:

[0020] This high school three-view teaching demonstration structure uses the components of the three-view demonstration assembly, particularly the transparent base plate, transparent frame plate, and transparent top cover, to allow students to directly observe the actual projection of the demonstrated shape from different viewing angles. This intuitive teaching method is more vivid and easier to understand than traditional flat drawings.

[0021] Because the demonstration turntable can rotate freely and the three-view demonstration frame can be flipped, students can change the viewing angle through manual operation, which enhances the interactivity in the classroom. This not only increases students' interest but also deepens their understanding of spatial geometry concepts.

[0022] The demonstration transparent bottom plate, demonstration transparent frame plate and demonstration transparent top cover made of transparent materials ensure good visual penetration, ensuring that students can clearly see the outline and details of the to-be-demonstrated shape from multiple directions, thereby obtaining more accurate visual information.

However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0031] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0032] This embodiment provides Figures 1 to 4 The structure shown is a three-view teaching demonstration structure for high schools, comprising: a three-view demonstration assembly 1, a demonstration turntable 4, and a three-view demonstration frame component 5.

[0033] In this embodiment, the three-view demonstration assembly 1 is used for high school three-view chapter teaching demonstration. The three-view demonstration assembly 1 includes a demonstration support plate 2; the demonstration support plate 2 serves as a supporting base, carrying and fixing the entire demonstration structure, and is conveniently carried and moved to the classroom through the handle 3.

[0034] In this embodiment, the demonstration turntable 4 is rotatably mounted on the top surface of the demonstration support plate 2; the demonstration turntable 4 can rotate around the rotation axis 20, allowing the to-be-demonstrated shape 14 to be displayed at different angles, thereby achieving a full-view teaching demonstration.

[0035] In this embodiment, the three-view demonstration frame assembly 5 is arranged on the top surface of the demonstration turntable 4, and one end of the bottom of the three-view demonstration frame assembly 5 is hinged to the top surface of the demonstration turntable 4 for flipping the three-view demonstration frame assembly 5 for use; the three-view demonstration frame assembly 5 includes a demonstration transparent bottom plate 6, a demonstration transparent frame plate 7 and a demonstration transparent top cover 8, which together enclose a space to place the object 14 to be demonstrated, and the object can be observed from multiple angles.

[0036] In this embodiment, the three-view demonstration frame assembly 5 includes a demonstration transparent bottom plate 6 hinged to the top surface of the demonstration turntable 4 at one end, a demonstration transparent frame plate 7 fixed to the top surface of the demonstration transparent bottom plate 6, and a demonstration transparent top cover 8 detachably mounted on the top surface of the demonstration transparent frame plate 7. A shape to be demonstrated 14 is set up in the middle position of the top surface of the demonstration transparent bottom plate 6 through a support assembly. The demonstration transparent frame plate 7 encloses the shape to be demonstrated 14, so that views of the shape to be demonstrated 14 in different orientations can be demonstrated from any direction around the demonstration transparent frame plate 7, from the top surface of the demonstration transparent top cover 8, and by flipping the demonstration transparent bottom plate 6.

[0037] In this embodiment, a hinged flip groove 18 is formed on the peripheral edge of the top surface of the demonstration turntable 4 , and hinged ear plates 19 are fixed on both sides of the hinged flip groove 18 and located on the top surface of the demonstration turntable 4 .

[0038] In this embodiment, pins 15 are fixed to the outer walls of one end of the transparent demonstration base plate 6 on both sides. These pins 15 intersect with two hinged lugs 19, respectively, so that the hinged end of the transparent demonstration base plate 6 protrudes above the hinged flip groove 18. This allows the hinged end of the transparent demonstration base plate 6 to flip within the hinged flip groove 18 when the transparent demonstration base plate 6 is flipped. The pins 15 cooperate with the hinged lugs 19 to allow the transparent demonstration base plate 6 to flip, increasing the viewing angle. The hinged flip groove 18 provides space for the pins 15 to rotate, allowing the transparent demonstration base plate 6 to flip.

[0039] In this embodiment, a bearing 21 is embedded in the middle of the top surface of the demonstration support plate 2, and the inner ring of the bearing 21 is interference fit with the rotating shaft 20, and the top end of the rotating shaft 20 is fixedly connected to the center position of the bottom surface of the demonstration turntable 4.

[0040] In this embodiment, a plurality of latch holes 16 are symmetrically opened on the top surface of the demonstration transparent frame plate 7 , and a plurality of latch columns 17 are symmetrically connected to the edge side of the bottom surface of the demonstration transparent top cover 8 .

[0041] In this embodiment, when the clamping column 17 is adapted to be inserted into the clamping hole 16 , the demonstration transparent top cover 8 covers the top surface of the demonstration transparent frame plate 7 .

[0042] In this embodiment, the support assembly includes a transparent column 10 fixed to the center of the top surface of the demonstration transparent base plate 6, and a transparent support plate 11 fixed to the top of the transparent column 10. The transparent support plate 11 is fixedly connected to the object to be demonstrated 14 via a magnetic attraction. The transparent column 10 and the transparent support plate 11 constitute the support assembly, which is used to stably support the object to be demonstrated 14 and maintain its stability via the magnetic attraction.

[0043] In this embodiment, the magnetic attraction element includes a first magnet 12 embedded in the top surface of a transparent support plate 11 and a second magnet 13 embedded in the bottom surface of a figure to be demonstrated 14. The first magnet 12 and the second magnet 13 are magnetically attracted to each other. The first magnet 12 and the second magnet 13 form a magnetic attraction element, ensuring that the figure to be demonstrated 14 is stably positioned on the transparent support plate 11, preventing accidental movement during the demonstration.

[0044] In this embodiment, labels 9 for marking different views are provided on the bottom surface of the demonstration transparent base plate 6, the outer wall of the demonstration transparent frame plate 7, and the corner of the top surface of the demonstration transparent top cover 8. The labels 9 help identify the positions of different views, assisting in clarifying which view is currently being observed during teaching.

[0045] In this embodiment, handles 3 are fixed to the outer walls of both sides of the demonstration support plate 2. The three-view demonstration assembly 1 is carried to the classroom via the handles 3, the demonstration support plate 2 is placed on the podium, the demonstration transparent top cover 8 is opened and the object 14 to be demonstrated is placed. When the three views need to be viewed, the side directly in front of the demonstration transparent frame plate 7 and facing the students is the main view, and the left side of the demonstration transparent frame plate 7 or when the demonstration support plate 2 is rotated so that the left side of the demonstration transparent frame plate 7 facing the students is the left view. The students look down at the object 14 to be demonstrated through the demonstration transparent top cover 8 to obtain a top view, or flip the entire three-view demonstration frame assembly 5 under the hinged action of the pin 15 so that the top view of the object 14 to be demonstrated can be seen when the demonstration transparent top cover 8 faces the students, thereby obtaining the three views. The remaining views can be obtained by viewing the demonstration transparent frame plate 7 from different angles.

[0046] Working principle:

[0047] This is a high school three-view teaching demonstration structure. Teachers or students carry the three-view demonstration assembly 1 to the classroom using handle 3 and place it on the podium. The teacher then opens the transparent top cover 8, selects a suitable figure 14 to be demonstrated, and places it on the transparent bottom plate 6. The figure 14 is secured by the magnetic attraction between the first magnet block 12 and the second magnet block 13. The transparent top cover 8 is then replaced on top of the transparent frame plate 7, ensuring that the latch 17 is accurately inserted into the latch hole 16 to ensure that the top cover stably covers the transparent frame plate 7.

[0048] Make sure that the side in front of the demonstration transparent frame plate 7 faces the students, so that the students can see the main view of the shape to be demonstrated 14. The marking label 9 can help identify the current view as "main view". By manually rotating the demonstration turntable 4, the entire demonstration structure is rotated smoothly by utilizing the cooperation of the rotating shaft 20 and the bearing 21, until the left side of the demonstration transparent frame plate 7 faces the students. At this time, what is displayed is the left view of the shape to be demonstrated 14. It can also be marked by the marking label 9. Students can directly look down at the shape to be demonstrated 14 through the demonstration transparent top cover 8 and obtain its top view. Or the teacher can use the connection between the pin 15 and the hinged ear plate 19, and the space provided by the hinged flip groove 18 to flip the demonstration transparent bottom plate 6 so that the demonstration transparent top cover 8 faces the students, and the top view of the shape to be demonstrated 14 can also be displayed like this.

[0049] In addition to the main view, left view and top view, by further rotating the demonstration turntable 4 and adjusting the position of the demonstration transparent bottom plate 6, views from other perspectives such as the rear view and right view of the shape to be demonstrated 14 can be displayed.

[0050] When the teaching demonstration is finished, the teacher can open the transparent top cover 8, remove the figure to be demonstrated 14, and then close the top cover. The device can be conveniently moved by the handle 3 and stored or taken to the next class for continued use.
