Description

Technical Field

[0001] This utility model belongs to the field of teaching equipment technology, and in particular relates to a three-dimensional model teaching and display device. Background Technology

[0002] In the vocational high school mathematics curriculum, solid geometry is a core module for cultivating students' spatial imagination and logical reasoning abilities, and it is also a key focus and challenge in the teaching process. Because vocational high school students tend to have a concrete understanding, relying solely on textbook diagrams and blackboard drawings is insufficient for them to fully perceive the spatial structure of geometric solids. Therefore, solid models become a crucial tool to support teaching.

[0003] Some devices use bolts, clips, and other fixing methods. When changing different types of three-dimensional models, multiple parts need to be disassembled, which is cumbersome and time-consuming, resulting in a significant amount of classroom teaching time being occupied. In addition, teachers directly hold the models to demonstrate, which can easily cause arm fatigue after a long period of operation. Furthermore, the models have poor stability, making it difficult to ensure that all students can clearly observe them. Summary of the Invention

[0004] In response to the above situation, in order to overcome the shortcomings of the existing technology in terms of poor ease of operation.

[0005] The technical solution adopted by this utility model is as follows: A three-dimensional model teaching and display device includes a base layer, a rotating component, and a fixing component. The base layer is shaped like a frustum and a protective cover is threaded onto it. The rotating component is disposed on the base layer, and the fixing component is disposed on the upper end of the rotating component. The fixing component includes a fixing rod, a fixing plate, and a enclosure. The fixing rod is fixed to the upper end of the rotating component, and a permanent magnet is fixed to the upper end of the fixing rod. The lower end of the fixing plate has a positioning hole that matches the upper end of the fixing rod, and the permanent magnet at the upper end of the fixing plate is engaged in the positioning hole. The enclosure is fixed to the middle of the upper end of the fixing plate, and a second permanent magnet that matches the first permanent magnet is adhered to the enclosing part of the enclosure.

[0006] Furthermore, the rotating assembly includes a turntable, a rotating groove is provided on the upper end of the base layer, the turntable is rotatably disposed inside the rotating groove, and the center of the turntable is perpendicularly fixed to the output shaft of the rotary motor. The rotary motor is fixed inside the base layer, and a square fixing hole is provided on the turntable. The lower end of the fixing rod is inserted into the square fixing hole through clearance fit.

[0007] Furthermore, the fixing plate is polygonal or circular in shape, and the fixing plate is made of transparent ABS plastic.

[0008] Furthermore, an LED spotlight is provided on the upper part of the base layer, and a microprocessor and a battery are also provided inside the base layer. The battery, LED spotlight and rotary motor are electrically connected to the microprocessor through wires.

[0009] Furthermore, the protective cover is cylindrical in shape and is made of transparent acrylic material.

[0010] The beneficial effects of this utility model after adopting the above structure are as follows:

[0011] This invention utilizes the attraction between permanent magnet one and permanent magnet two, combined with the matching of the positioning holes on the fixing rod and the fixing plate, and the square fixing holes on the turntable, to replace the cumbersome fixing methods such as traditional bolts and buckles. When changing different three-dimensional models, it is not necessary to disassemble multiple parts; it can be done simply by attraction or removal. This prevents the problem of cumbersome and time-consuming operation of the device, reduces the time occupied in classroom teaching, and improves teaching efficiency. Attached Figure Description

[0019] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0021] like Figures 1-3 As shown, a three-dimensional model teaching and display device includes a base layer, a rotating component, and a fixing component. The base layer is frustum-shaped and has a protective cover threaded onto it. The rotating component is mounted on the base layer, and the fixing component is mounted on the upper end of the rotating component. The fixing component includes a fixing rod, a fixing plate, and a enclosure. The fixing rod is fixed to the upper end of the rotating component, and a permanent magnet is fixed to the upper end of the fixing rod. The lower end of the fixing plate has a positioning hole that matches the upper end of the fixing rod, and the permanent magnet is engaged in the positioning hole. The enclosure is fixed to the middle of the upper end of the fixing plate, and a second permanent magnet that matches the first permanent magnet is adhered to the enclosing part of the enclosure.

[0022] In one embodiment of this utility model, such as Figures 2-3 As shown, the rotating assembly includes a turntable, a rotating groove is provided on the upper end of the base layer, the turntable is rotatably disposed inside the rotating groove, and the center of the turntable is perpendicularly fixed to the output shaft of the rotary motor. The rotary motor is fixed inside the base layer, and a square fixing hole is provided on the turntable. The lower end of the fixing rod is inserted into the square fixing hole through clearance fit.

[0023] In one embodiment of this utility model, such as Figure 2 As shown, the fixing plate is polygonal or circular in shape and is made of transparent ABS plastic.

[0024] In one embodiment of this utility model, such as Figure 2 As shown, an LED spotlight is also provided on the upper end of the base layer, and a microprocessor and a battery are also provided inside the base layer. The battery, LED spotlight and rotary motor are electrically connected to the microprocessor through wires.

[0025] In one embodiment of this utility model, such as Figures 1-2 As shown, the protective cover 11 is cylindrical and made of transparent acrylic material, which can protect the model without affecting observation.

[0026] In practical use, the corresponding fixing plate 25 is replaced according to the three-dimensional model. The fixed plate 25 is then attached and secured by the permanent magnet 252. The display section and unfolded parts of the corresponding three-dimensional model are fixed to the edge of the fixing plate 25. The transparent protective cover 11 is tightened. The microprocessor starts the rotating motor 21 to drive the turntable 22 to rotate. At the same time, the microprocessor switches the color of the LED spotlight 12 through the controller. Red light is used to view the edges, blue light is used to view the bottom surface, and white light is used to view the whole.
