Description

Technical Field

[0001] The invention relates to the technical field of teaching aids, and in particular to a combined multifunctional teaching aid. Background Art

[0002] The role of the globe teaching aid in teaching is multifaceted. It is not only a basic tool for geography learning, but also an important auxiliary means to cultivate students' spatial thinking and understand the principles of earth science. The globe teaching aid has the advantages of intuitively displaying the shape and size of the earth, displaying the geographical distribution, helping students form a global perspective, understand geographical spatial relationships, and assisting in understanding the movement of the earth.

[0003] In order to enhance functionality, existing globe teaching aids often adopt a cut-away design, aiming to simultaneously display the surface map and internal structure of the earth. Although the original intention of this design was to enrich the teaching experience, it has brought about a significant problem in actual operation: the surface map of the cut globe is incomplete due to cutting, making it difficult to fully and clearly display geographical details, which undoubtedly adds unnecessary troubles and complexity to teaching. Summary of the invention

[0004] The disclosed embodiment relates to a combined multifunctional teaching aid, which arranges a globe into two parts, a display main sphere and a display auxiliary sphere. The display main sphere and the display auxiliary sphere can be combined to form a complete earth structure, which is convenient for teaching personnel to use the completed earth structure to explain the geographical distribution on the map surface. By disassembling the display auxiliary sphere, a fan-shaped gap can be presented on the display main sphere. The gap can be used to display the inner and outer cores, mantle and crust of the earth, which is convenient for teaching personnel to use the earth structure with the gap to explain the internal structure of the earth. In this way, the teaching aid has two model states, which is convenient for teaching personnel to use models in different states to explain different knowledge according to teaching needs.

[0007] In at least some embodiments, a spherical structure is fixed at the central position inside the main display sphere, and this spherical structure represents the core.

[0008] In at least some embodiments, three layers of paint with different colors are sprayed from the inside to the outside at the sector-shaped notch of the main display sphere, and the three layers of paint with different colors represent the outer core, the mantle, and the crust in sequence from the inside to the outside.

[0009] In at least some embodiments, a travel groove is provided inside the installation rotating seat; a conversion column is slidably inserted at the central position inside the travel groove; a side groove is provided on the outer wall of the installation rotating seat; the outer end of the conversion column is in a hemispherical structure, and the hemispherical structure of the conversion column is also slidably installed inside the conversion groove.

[0010] In at least some embodiments, a spring B is jointly embedded between the inner side of the conversion column and the inner end of the travel groove; a plugging rod is fixedly installed at the inner end of the conversion column; a pushing block is fixedly installed on the circumferential outer wall of the plugging rod.

[0011] In at least some embodiments, the side groove is further in communication with the stroke groove; a baffle is fixedly installed in the side groove; a resistance increasing block is slidably installed inside the side groove; the inner end of the resistance increasing block is of an inclined structure; a spring C is jointly embedded between the inside of the resistance increasing block and the baffle; when the top pushing block moves outwards, it will push against the inclined surface of the resistance increasing block.

[0012] In at least some embodiments, a slot is provided between the mounting rotating seat and the main display sphere; a plug piece is inserted into the slot; a plugging hole is provided on the outer side of the plug piece; the inner diameter of the plugging hole matches the diameter of the plugging rod; the inner end of the plug piece is fixedly installed with a secondary display sphere; the shape of the secondary display sphere is the same as the sector-shaped notch on the main display sphere.

[0013] In at least some embodiments, a world map is jointly sprayed on the outer walls of the secondary display sphere and the main display sphere; the secondary display sphere is also clamped inside the main display sphere; the limiting column can be selectively inserted into one of the limiting holes.

[0014] In at least some embodiments, when the hemispherical structure of the conversion column slides into the high position of the conversion groove, the conversion column will move inwards and drive the plugging rod to be inserted into the plugging hole; when the hemispherical structure of the conversion column slides into the low position of the conversion groove, the conversion column will move outwards and drive the plugging rod to disengage from the plugging hole.

[0015] The present invention provides a combined multifunctional teaching aid, which has the following beneficial effects: 1. By innovatively designing the globe to include two main parts, namely the main display sphere and the secondary display sphere, the ingenious combination of these two parts can completely reproduce the external structure of the earth, providing a teaching staff with an intuitive and comprehensive teaching tool. During teaching, teachers can use this complete earth structure to explain in detail various geographical distribution features on the map surface, including key information such as continental plates, ocean distributions, national boundaries, etc. And when it is necessary to deeply explore the internal structure of the earth, by simply disassembling the secondary display sphere, a clear sector-shaped notch will appear on the main display sphere, and through the notch, the inner and outer cores, mantle and crust inside the earth can be revealed. In this way, the teaching means are greatly enriched, enabling teachers to flexibly switch the state of the teaching aid according to different teaching contents.

[0016] 2. The present invention has a convenient disassembly and state switching mechanism. When the secondary display sphere is in a fixed state, only by rotating the sliding frame counterclockwise, it is possible to easily control the plugging rod to disengage from the plugging hole, thereby releasing the rigid connection between the secondary display sphere and the main display sphere. This operation is simple and fast, without complex steps, greatly improving the convenience of the state switching of the teaching aid.

[0017] 3. While the insertion rod disengages from the insertion hole, the resistance increasing block will move outward under the synergistic action of relevant structures and generate friction with the mounting ring, thereby effectively increasing the resistance between the mounting ring and the mounting rotating seat. This design enables the display main sphere to relatively stably maintain the notch part facing a specific required direction after disassembling the display secondary sphere, providing strong support for the detailed display of the internal structure of the earth.

[0018] 4. With its unique dual - model state design and convenient disassembly and state - switching mechanism, this teaching aid brings higher flexibility and convenience to geography teaching. It meets the needs of teachers for different teaching contents through its multi - functional model states, enabling the teaching work to be carried out faster and better.

Specific embodiments

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0023] Please refer to Figures 1 to 8 :

[0024] Embodiment 1. The present invention provides a combined multi-functional teaching aid, including: a teaching aid base 1, on the top of which is fixedly installed a support frame 2 with an arc structure; on the circumferential inner wall of the support frame 2 is provided a conversion groove 3; one side inside the conversion groove 3 is higher than the other side, and the high and low surfaces are connected by an inclined plane; on the circumferential inner wall of the support frame 2 is also provided a guide groove 4; the guide groove 4 is located between two conversion grooves 3; on the circumferential outer wall of the support frame 2 is provided a communication groove 5, and the communication groove 5 is connected to the guide groove 4; the width of the communication groove 5 is smaller than that of the guide groove 4; two limit holes 6 are provided inside the guide groove 4; a slide block 7 is slidably installed inside the guide groove 4; a shrinkage groove 8 is provided inside the slide block 7; a limit post 9 is slidably installed inside the shrinkage groove 8; between the left end of the limit post 9 and the left side inside the shrinkage groove 8 is jointly embedded with a spring A 10; the right end of the limit post 9 is fixedly installed with a connecting post 11; the diameter of the connecting post 11 is smaller than that of the limit post 9, and the connecting post 11 is also slidably installed inside the communication groove 5; the outer end of the connecting post 11 is fixedly installed with a pressure plate 12 in a disc shape; the pressure plate 12 is located outside the support frame 2; the left end of the slide block 7 is fixedly installed with a slide frame 13 with an arc structure.

[0025] By setting the globe to include two parts, namely the main display sphere 25 and the secondary display sphere 29, the combination of the main display sphere 25 and the secondary display sphere 29 can form a complete earth structure, facilitating teaching staff to explain the geographical distribution on the map surface using the complete earth structure. By disassembling the secondary display sphere 29, a sector-shaped notch can be presented on the main display sphere 25. Using this notch, the inner and outer cores, mantle, and crust inside the earth can be shown, facilitating teaching staff to explain the internal structure of the earth using the globe structure with the notch. Thus, this teaching aid has two model states, enabling teaching staff to use models in different states to explain different knowledge according to teaching needs.

[0026] Embodiment 2: Based on Embodiment 1, an installation ring 14 is fixedly installed at both ends of the sliding frame 13; an installation rotating seat 15 is rotatably installed inside the installation ring 14; the inner end of the installation rotating seat 15 is fixedly installed with the main display sphere 25; a sector-shaped notch is provided on the outer wall of the main display sphere 25; a spherical structure is fixed at the center position inside the main display sphere 25, and this spherical structure represents the inner core; three layers of paint with different colors are sprayed from the inside out at the sector-shaped notch of the main display sphere 25, and the three layers of paint with different colors represent the outer core, mantle, and crust from the inside out in sequence; a travel groove 16 is provided inside the installation rotating seat 15; a conversion column 17 is slidably inserted at the center position inside the travel groove 16; the outer end of the conversion column 17 is in a hemispherical structure, and the hemispherical structure of the conversion column 17 is also slidably installed inside the conversion groove 3; a spring B18 is jointly installed between the inner side of the conversion column 17 and the inner end of the travel groove 16; the inner end of the conversion column 17 is also fixedly installed with a plugging rod 19; a side groove 21 is provided on the outer wall of the installation rotating seat 15; a pushing block 20 is fixedly installed on the circumferential outer wall of the plugging rod 19.

[0027] When the secondary display sphere 29 in the present invention is in a fixed state, only by rotating the sliding frame 13 counterclockwise can the plugging rod 19 be indirectly controlled to disengage from the inside of the plugging hole 28, making the connection between the secondary display sphere 29 and the main display sphere 25 lack a rigid connection, facilitating the disassembly of the secondary display sphere 29 and enabling the teaching aid to be in the state of teaching the internal structure of the earth. The disassembly method of the secondary display sphere 29 is simple, enabling the state switching of this teaching aid to be fast and improving the usability of this teaching aid.

[0028] Embodiment 3, based on Embodiment 2, the side groove 21 is also communicated with the stroke groove 16; a baffle 22 is fixedly installed on the side groove 21; a resistance increasing block 23 is also slidably installed inside the side groove 21; the inner end of the resistance increasing block 23 is of an inclined structure; a spring C24 is jointly embedded between the inside of the resistance increasing block 23 and the baffle 22; when the pushing block 20 moves outwards, it will push the inclined surface of the resistance increasing block 23; a slot 26 is formed between the mounting turntable 15 and the main display sphere 25; a plug piece 27 is inserted into the inside of the slot 26; a plugging hole 28 is formed on the outer side of the plug piece 27; the inner diameter of the plugging hole 28 matches the diameter of the plugging rod 19; the inner end of the plug piece 27 is fixedly installed with a secondary display sphere 29; the shape of the secondary display sphere 29 is the same as the sector-shaped notch on the main display sphere 25; a world map is jointly sprayed on the outer walls of the secondary display sphere 29 and the main display sphere 25; the secondary display sphere 29 is also clamped inside the main display sphere 25; the limiting column 9 can be selectively inserted into the inside of one of the limiting holes 6; when the hemispherical structure of the conversion column 17 slides into the high position of the conversion groove 3, the conversion column 17 will move inwards and drive the plugging rod 19 to be inserted into the inside of the plugging hole 28; when the hemispherical structure of the conversion column 17 slides into the low position of the conversion groove 3, the conversion column 17 will move outwards and drive the plugging rod 19 to disengage from the inside of the plugging hole 28.

[0029] When the plugging rod 19 disengages from the inside of the plugging hole 28, the resistance increasing block 23 will also move outwards under the cooperation of the corresponding structure, so that the resistance increasing block 23 rubs against the mounting ring 14 through outward movement, increasing the resistance between the mounting ring 14 and the mounting turntable 15, thereby making the main display sphere 25 not easy to rotate, facilitating the main display sphere 25 to display the notch part forward, and improving the stability of the main display sphere 25 when displaying the internal structure of the earth.

[0030] When it is necessary to switch the teaching aid from the state of showing the earth's surface to the state of showing the interior of the earth, the teaching staff only need to press the pressure plate 12, so that it drives the connecting column 11 and the limiting column 9 to move inward, so that the limiting column 9 disengages from the inside of the lower limiting hole 6, and then slide the sliding block 7 along the guiding groove 4, so that the sliding block 7 drives the sliding frame 13, the main display sphere 25 and the auxiliary display sphere 29 to rotate, so that the auxiliary display sphere 29 rotates to the vertical state. At this time, when the hemispherical structure of the plugging rod 19 slides into the low position of the conversion groove 3, the conversion column 17 drives the plugging rod 19 to move outward under the action of the spring B18, so that the end of the plugging rod 19 disengages from the inside of the plugging hole 28, making the connection between the inserting piece 27 and the inserting slot 26 lack a rigid connection, which is convenient for the staff to disassemble the auxiliary display sphere 29 and convert the teaching aid into the state of showing the interior of the earth. Moreover, when the plugging rod 19 moves outward, the plugging rod 19 will also drive the pushing block 20 to move outward, so that the pushing block 20 pushes the inclined surface of the resistance increasing block 23, causing its outer wall to move outward under force and contact with the inner wall of the mounting ring 14, so that the main display sphere 25 becomes not easy to rotate, facilitating the teaching aid in the state of showing the interior of the earth to be stable enough. Finally, release the pressing on the pressure plate 12, so that the limiting column 9 moves outward and returns to its original position under the action of the spring A10 and inserts into the upper limiting hole 6, so that the teaching aid is stably maintained in the state of showing the interior of the earth.
