Description

Technical Field

[0001] This utility model relates to the field of teaching aids technology, and more specifically, to a splicing twelve constellation disc teaching aid. Background Technology

[0002] In astronomy teaching, popular science activities, and the dissemination of constellation culture, the twelve-constellation chart is a core tool for intuitively demonstrating the distribution, movement patterns, and related cultural knowledge of constellations. It is widely used in school classrooms, science exhibition halls, and astronomy interest groups. The core function of this type of teaching aid relies on assembling components printed with constellation photos, text descriptions, star charts, and other information to form a complete and demonstrative twelve-constellation chart structure, allowing users to clearly observe and interact with it.

[0003] The mainstream zodiac-themed educational toys currently on the market have significant flaws in their assembly structure design, making it difficult to meet the needs for convenient and efficient use and severely restricting their application in teaching and popular science scenarios. One of the most common methods is bolt-fastening assembly: this method requires multiple sets of bolts to fix each zodiac information component to the disc frame. Operators must use screwdrivers and other specialized tools to align and tighten each bolt hole individually, which is not only cumbersome but also time-consuming for each assembly. More importantly, when it is necessary to change components with different zodiac content according to the teaching theme, or to disassemble and store the educational toy, tools must be used to disassemble the bolts again, resulting in extremely low operational efficiency. Repeated disassembly and reassembly can easily lead to wear on the bolt holes and stripping of the threads, shortening the lifespan of the educational toy. Another common assembly method is glue bonding: although it can quickly connect components in the initial assembly stage, it is a permanent, non-removable fixed structure. On the one hand, if a constellation information component has problems such as blurry printing or damage, it cannot be replaced individually and the entire teaching aid must be scrapped, resulting in waste of resources and increased usage costs. On the other hand, as the teaching content is updated, the component content cannot be iteratively upgraded, causing the practicality of the teaching aid to decline rapidly over time and making it difficult to adapt to dynamically changing teaching needs. Therefore, it is necessary to improve it. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a modular twelve-constellation disc teaching aid, which has the advantages of being able to quickly assemble constellation information components without the need for special tools, and being able to flexibly replace components, thus greatly improving assembly efficiency and usage flexibility.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular twelve-constellation disc teaching aid, comprising: A circular plate, wherein a baffle is fixedly installed at the top of the circular plate, and a threaded sleeve is fixedly fitted inside the circular plate and the baffle; An assembly mechanism is disposed on the outer surface of the circular plate; The assembly mechanism includes a first hinge block, the outer surface of which is fixedly connected to the outer surface of the circular plate. A rotating rod is hinged to the first hinge block, the top end of which abuts against the bottom end of the baffle. A positioning block is fixedly installed on the outer surface of the rotating rod, and a fixing plate is inserted into the inside of the positioning block. The fixing plate is provided with constellation-related photos and text. An arc-shaped plate is inserted into the outer surface of the fixing plate, and an insert block is fixedly installed on the outer surface of the arc-shaped plate. The insert block is inserted into the inside of the rotating rod.

[0006] As a preferred embodiment of this utility model, a screw is threaded into the inner thread of the threaded sleeve, a fixing block is movably sleeved at the bottom end of the screw, and a turning block is fixedly installed at the top end of the screw.

[0007] As a preferred embodiment of this utility model, a second hinge block is fixedly installed on the top of the fixed block, a connecting rod is hinged on the second hinge block, and a third hinge block is hinged to the end of the connecting rod away from the second hinge block. The top of the third hinge block is fixedly connected to the bottom of the rotating rod.

[0008] As a preferred embodiment of this utility model, a base is fixedly installed at the bottom end of the fixing block, and an anti-slip pad is fixedly installed at the bottom end of the base.

[0009] As a preferred embodiment of this utility model, a round shaft is movably sleeved inside the bottom end of the base, and a handle is fixedly installed on the outer surface of the round shaft, with the handle fitting snugly against the inside of the bottom end of the base.

[0010] As a preferred embodiment of this utility model, a first magnet is fixedly installed inside the handle, a second magnet is attached to the top of the first magnet, and the second magnet is fixedly sleeved with the bottom of the base.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the design of its assembly mechanism, allows operators to simply place the fixing plate between the rotating rods after the rotating rods have unfolded, allowing the fixing plate to naturally insert into the positioning block, thus completing the initial positioning of the fixing plate. Then, holding the curved plate, the operator aligns the outer surface of the curved plate with the outer surface of the fixing plate and inserts it. At this time, the insert on the curved plate will simultaneously insert into the rotating rod. Through the cooperation of the curved plate and the positioning block, the fixing plate is quickly and securely assembled. The entire assembly process requires no complex operating steps or professional skills. Whether teachers quickly assemble the teaching aid in the classroom or students participate in the assembly learning independently, it can be completed efficiently, significantly shortening assembly time and effectively improving the flexibility and adaptability of the teaching aid in teaching scenarios.

[0012] 2. This utility model achieves dual optimization in portability: On the one hand, through the coordinated action of the twisting block, screw, connecting rod, and other structures, the rotating rod can be quickly unfolded and retracted. It can quickly unfold the rotating rod to meet the needs of teaching and demonstration, and can also be reversed to retract the rotating rod, greatly reducing the overall volume of the teaching aid and making it easy to store. On the other hand, the bottom of the base is designed with a rotatable handle for storage. When moving, simply invert the device and rotate the handle to fit it. You can easily carry the device by holding the handle without any additional carrying tools. After resetting, the handle is fixed by the attraction of the first magnet and the second magnet, preventing shaking during carrying or use. This makes the teaching aid space-saving and reduces the difficulty of carrying, whether it is transferred between classrooms, carried in outdoor astronomical science activities, or stored after class, significantly improving the portability and practicality of the teaching aid.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 6 As shown, this utility model provides a modular twelve-constellation disc teaching aid, comprising: A circular plate 1, a baffle 2 is fixedly installed on the top of the circular plate 1, and a threaded sleeve 3 is fixedly sleeved inside the circular plate 1 and the baffle 2; An assembly mechanism is installed on the outer surface of the circular plate 1; The assembly mechanism includes a first hinge block 4, the outer surface of which is fixedly connected to the outer surface of the circular plate 1. A rotating rod 5 is hinged to the first hinge block 4, the top end of which abuts against the bottom end of the baffle 2. A positioning block 6 is fixedly installed on the outer surface of the rotating rod 5. A fixing plate 7 is inserted into the inside of the positioning block 6. Constellation-related photos and text are set on the fixing plate 7. An arc-shaped plate 8 is inserted into the outer surface of the fixing plate 7. An insert block 9 is fixedly installed on the outer surface of the arc-shaped plate 8 and inserted into the inside of the rotating rod 5.

[0017] The circular plate 1 provides a fixed mounting base for the baffle 2 and the assembly mechanism. The baffle 2, on the one hand, can limit and position the rotation of the rotating rod 5 by abutting against its top end when the rotating rod 5 is extended; on the other hand, it cooperates with the circular plate 1 to form a basic frame. The threaded sleeve 3 is fixedly fitted inside the circular plate 1 and the baffle 2, used to cooperate with subsequent structures to achieve the overall displacement of the circular plate 1 and the baffle 2, thereby driving the assembly mechanism. The assembly mechanism is fixedly connected to the circular plate 1 through the first hinge block 4, which provides a hinge support point for the rotating rod 5, allowing the rotating rod 5 to rotate around it. When unfolded or folded, the rotating rod 5 provides an installation carrier for the positioning block 6. The positioning block 6 is used to insert the fixing plate 7, realizing the initial positioning and support of the fixing plate 7. The fixing plate 7, as the carrier of constellation information, realizes the teaching and popular science function through the constellation-related photos and texts set on it. After the arc plate 8 is inserted into the outer surface of the fixing plate 7, it can be inserted into the rotating rod 5 through the insert 9 on its outer surface, and then cooperate with the positioning block 6 to form a fixation of the fixing plate 7, ensuring that the fixing plate 7 will not loosen or shift during use. Finally, through the cooperation of various structures, the teaching aid can be easily assembled and constellation information can be displayed.

[0018] Among them, the threaded sleeve 3 is threaded with a screw 10, the bottom end of the screw 10 is movably fitted with a fixing block 11, and the top end of the screw 10 is fixedly installed with a screwing block 12.

[0019] The threaded sleeve 3 is internally threaded to the screw 10, so that when the screw 10 rotates, it can drive the threaded sleeve 3 and the circular plate 1 and baffle 2 fixed thereto to move as a whole through the threaded transmission, providing power for the operation of the assembly mechanism; the bottom end of the screw 10 is movably sleeved with the fixing block 11, and the fixing block 11 provides rotational support for the screw 10; the screwing block 12 is fixedly installed on the top end of the screw 10, providing the operator with a convenient force application component. The operator can easily drive the screw 10 to rotate by turning the screwing block 12 without the need for special tools, simplifying the operation process.

[0020] The top of the fixed block 11 is fixedly installed with a second hinge block 13, a connecting rod 14 is hinged on the second hinge block 13, and a third hinge block 15 is hinged to the end of the connecting rod 14 away from the second hinge block 13. The top of the third hinge block 15 is fixedly connected to the bottom of the rotating rod 5.

[0021] The second hinge block 13 is fixedly installed on the top of the fixed block 11, providing a hinge support point for the connecting rod 14, allowing the connecting rod 14 to rotate flexibly around it. The two ends of the connecting rod 14 are respectively hinged to the second hinge block 13 and the third hinge block 15, forming a transmission connection structure, which is used to associate the fixed position of the fixed block 11 with the movement state of the rotating rod 5. The third hinge block 15 is fixedly connected to the bottom end of the rotating rod 5, and can move synchronously with the movement of the rotating rod 5, thereby driving the connecting rod 14 to move. When the circular plate 1 drives the rotating rod 5 to move downward, the connecting rod 14 rotates around the second hinge block 13 under the drive of the third hinge block 15, and pushes the rotating rod 5 to rotate and unfold around the first hinge block 4 through the reaction force, realizing the linkage control of the unfolding action of the rotating rod 5, ensuring that multiple rotating rods 5 unfold synchronously and with consistent unfolding angles.

[0022] The base 16 is fixedly installed at the bottom of the fixing block 11, and the anti-slip pad 17 is fixedly installed at the bottom of the base 16.

[0023] The base 16 is fixedly installed at the bottom of the fixing block 11, serving as the bottom support structure of the teaching aid and providing a stable installation base for the entire teaching aid, allowing it to be placed stably. The anti-slip pad 17 is fixedly installed at the bottom of the base 16. Its material has a high coefficient of friction. When the teaching aid is placed on a flat surface such as a table, the anti-slip pad 17 can fit tightly against the contact surface, increasing the friction between the teaching aid and the contact surface, effectively preventing the teaching aid from sliding due to accidental contact during use, and further improving the overall placement stability of the teaching aid.

[0024] The base 16 has a circular shaft 18 that is movably connected to the bottom end of the base 16. A handle 19 is fixedly installed on the outer surface of the circular shaft 18 and fits into the bottom end of the base 16.

[0025] The round shaft 18 is movably sleeved inside the bottom end of the base 16, providing a rotational support shaft for the handle 19, allowing the handle 19 to rotate flexibly around the round shaft 18 as the axis, realizing the unfolding and retraction of the handle 19; the handle 19 is fixedly installed on the outer surface of the round shaft 18 and fits snugly inside the bottom end of the base 16. In the retracted state, it can be hidden inside the base 16 without occupying extra space, and in the unfolded state, it can be held by the operator, making it convenient to move the entire teaching aid without the need for other handling tools, thus improving the ease of movement of the teaching aid.

[0026] The handle 19 has a first magnet 20 fixedly installed inside, and a second magnet 21 is attached to the top of the first magnet 20. The second magnet 21 is fixedly connected to the bottom of the base 16.

[0027] The first magnet 20 is fixedly installed inside the handle 19, and the second magnet 21 is fixedly sleeved inside the bottom end of the base 16. When the handle 19 is rotated to the retracted state, the first magnet 20 and the second magnet 21 will approach each other and fit tightly together through magnetic attraction. The magnetic attraction will firmly fix the handle 19 inside the base 16, preventing the handle 19 from rotating and unfolding on its own due to vibration or other factors during the placement or use of the teaching aid, and ensuring the stability of the handle 19 in the retracted state.

[0028] Working principle and usage process of this utility model: When the operator needs to use this teaching aid, the device must first be moved to the target location. The operator can invert the device and then turn the two handles 19 inside the bottom of the base 16, causing them to rotate in opposite directions around their respective corresponding circular axes 18. When the outer surfaces of the two handles 19 come into contact with each other during rotation, the operator can move the entire device by holding these two contacting handles 19. After the device reaches the target location, the operator can then turn the two handles 19 in the opposite direction to reset them. At this point, the contents of the handles 19 will... The first magnet 20, which is fixedly installed, will come into contact with the second magnet 21, which is fixedly sleeved inside the bottom of the base 16, during the rotation. Due to the magnetic attraction between the first magnet 20 and the second magnet 21, the handle 19 will be stably attached to the inside of the base 16 without shaking. Then, the operator will place the device upright on the table, so that the anti-slip pad 17 fixedly installed at the bottom of the base 16 will be fully attached to the table. Since the anti-slip pad 17 has the property of increasing friction, it can effectively prevent the device from sliding on the table during use and ensure the overall stability of the device. Next, the operators begin unfolding and assembling the teaching aid. First, the screwing block 12, fixedly installed at the top of the screw 10, is screwed. This causes the screw 10 below it to rotate around its movable engagement point with the fixed block 11. Since the outer surface of the screw 10 is threadedly engaged with the threaded sleeve 3 inside the circular plate 1 and the baffle 2, when the screw 10 rotates, it causes the circular plate 1, the baffle 2, and the first hinge block 4 fixedly connected to the outer surface of the circular plate 1 to move downwards as a whole through the threaded sleeve 3. During this downward movement, several first hinge blocks 4 will respectively drive each... The self-hinged rotating rod 5 moves, and at the same time, the third hinge block 15 fixedly connected to the bottom end of the rotating rod 5 will drive the connecting rod 14 hinged to it to rotate around the second hinge block 13 fixedly installed at the top of the fixed block 11 as the axis. At this time, the rotating rod 5 will rotate around the first hinge block 4 as the axis under the reaction force of the connecting rod 14 while moving downward with the circular plate 1 as a whole. When the rotating rod 5 rotates to ninety degrees, it completes the unfolding action, and its outer surface will contact the bottom end of the baffle 2. At this time, the baffle 2 will block the further rotation of the rotating rod 5, thereby realizing the positioning of the rotating rod 5. Meanwhile, the included angle formed between several unfolded rotating rods 5 matches the fixed plate 7 printed with constellation-related photos and text. At this time, the operator can place the fixed plate 7 between adjacent rotating rods 5, and insert the edge of the fixed plate 7 into the positioning block 6 fixedly installed on the outer surface of the rotating rod 5 to complete the initial positioning of the fixed plate 7. After all the fixed plates 7 have been placed and initially positioned, the operator holds the arc-shaped plate 8, aligns the inner side of the arc-shaped plate 8 with the outer surface of the fixed plate 7 and inserts it. When the arc-shaped plate 8 and the fixed plate 7 are fully inserted, the insertion block 9 fixedly installed on the outer surface of the arc-shaped plate 8 will be inserted into the interior of the rotating rod 5 at the same time. At this time, the arc-shaped plate 8 and the positioning block 6 will cooperate to fix the fixed plate 7, thereby completing the assembly operation of the entire twelve constellation plate teaching aid. At this time, the operator can use the constellation-related photos and text on the fixed plate 7 for teaching or popular science demonstration. When the teaching aids need to be put away, the operator only needs to remove the arc plate 8 first, then pull the fixing plate 7 out of the positioning block 6, and then twist the twisting block 12 in the opposite direction, so that the screw 10 drives the circular plate 1, the baffle 2 and the first hinge block 4 to move upward as a whole through the threaded sleeve 3. At this time, the rotating rod 5 will rotate in the opposite direction around the first hinge block 4 under the drive of the connecting rod 14 and put away, finally returning to the initial state, so as to be stored or moved again later.
