Description

Technical Field

[0001] This utility model belongs to the field of teaching aids technology, specifically a four-star instrument teaching aid that can be assembled. Background Technology

[0002] In astronomy teaching and popular science, the four-planet array is often used to demonstrate the orbital patterns of Venus, Mars, Jupiter, and Saturn, helping learners understand the changing positions of celestial bodies. However, traditional four-planet arrays generally have the following shortcomings:

[0003] Fixed structure and lack of interactivity: Most existing four-star instruments are one-piece molded structures, which prevent learners from gaining a deeper understanding of their internal structure and working principle through hands-on assembly. This results in a lack of participation in the teaching process and makes it difficult to stimulate learning interest.

[0004] Limited functionality and limited demonstration effect: Some teaching aids can only display the trajectory of a single celestial body, or although they can demonstrate multiple celestial bodies, the scale design is complex and the operation is inconvenient. They cannot intuitively present the correspondence between the dynamic position of the celestial body and the time and date, which reduces teaching efficiency.

[0005] Insufficient applicability and safety: Some teaching aids have unpolished edges on their parts, making them prone to scratches during assembly, and the joints are unstable, affecting the user experience; at the same time, the functional design fails to take into account the needs of different learning scenarios, making it difficult to meet diverse teaching objectives. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an assemblable four-star instrument teaching aid, which solves the technical problems of traditional teaching aids having fixed structure, lack of interactivity, single function, and limited demonstration effect.

[0007] The solution adopted in this utility model is: an assemblable four-star instrument teaching aid, characterized in that it includes:

[0008] The components are detachable and assembleable, including a cross-shaped buckle, a Saturn disk, a Mars disk, a pointer disk, a Venus disk, and a four-planet disk;

[0009] The Saturn-Jupiter astrolabe is the largest astrolabe. The Mars astrolabe, pointer astrolabe, Venus astrolabe, and four-planet astrolabe are stacked on the Saturn-Jupiter astrolabe from bottom to top, and the centers of each astrolabe are fixedly connected by the cross buckle.

[0010] Each disc is marked with scale markings, including year markings, date markings, and direction indicator markings, which are used to predict the dynamic positions of Venus, Mars, Jupiter, and Saturn by coordinating the scale markings between the discs.

[0011] Preferably, the edges of the component parts are all polished.

[0012] Preferably, the inner ring of the Saturn disk has a year scale, the Mars disk has a designated date scale, the Venus disk has a triangular scale, and the four-planet disk has a year scale triangle. By aligning the triangular scale of the Venus disk with the year scale triangle of the four-planet disk, the dynamic position of Venus can be read.

[0013] Preferably, the pointer dial is provided with scale lines. By rotating the pointer dial, the scale lines are aligned with the "Earth" scale line on the Venus disk and the target date scale on the four-star disk. At the same time, the scale lines are aligned with the direction line from the "Earth+" mark to the "Mars+" mark to read the position of Mars in the zodiacal constellation.

[0014] Preferably, by rotating the pointer dial so that the scale line of the pointer dial points to the year scale corresponding to Jupiter or Saturn on the Saturn-Jupiter star chart, and combining this with the indicator red line on the Saturn-Jupiter star chart, the position of Jupiter or Saturn in the zodiac constellation can be determined.

[0015] Beneficial effects:

[0016] I. Enhancing Interactivity and Structural Understanding: Utilizing detachable and assembleable components, users must assemble parts such as the cross-shaped interlocking mechanism, the Saturnian star disk, and the Mars disk to gain a deeper understanding of the internal structure of the teaching aid and the stacking logic of each disk. The assembly process not only increases the sense of participation in learning but also visually demonstrates the mechanical principles of the four-star instrument, helping learners develop spatial thinking and deepen their understanding of the structure of astronomical teaching aids.

[0017] II. Simplified Astronomical Demonstrations, Enhanced Teaching Efficiency: The scale markings on each disc, through scientifically designed year, date, and direction indicator scales (the coordination of the Venus disc's triangle scale with the year scale triangle on the four-star disc), transform complex astronomical calculations into intuitive scale alignment operations. For example, when predicting Venus's movements, simply align the Venus disc triangle with the corresponding year scale on the four-star disc to quickly read Venus's position, eliminating the need for complex formulas, lowering the barrier to astronomical teaching, and improving demonstration efficiency.

[0018] III. Integrated Multi-Planet Dynamic Prediction Function: Through the linkage design of the pointer dial's scale lines and the scales of each dial, this teaching aid can simultaneously predict the positions of Venus, Mars, Jupiter, and Saturn. For example, by rotating the pointer dial to point the scale lines to the corresponding year's scale for Jupiter or Saturn on the Saturn-Jupiter disc (claim 5), and combining this with the red indicator line, the zodiacal constellation where the celestial body is located can be determined. This integrates the movement patterns of multiple celestial bodies into a single teaching aid, avoiding the shortcomings of traditional teaching aids with limited functionality and meeting diverse astronomical teaching needs.

[0019] Fourth, balancing practicality and fun: The modular structure and intuitive scale operation provide an interactive learning tool for astronomy teaching, enhancing learners' hands-on skills and stimulating their interest through the visualization of celestial position changes. Furthermore, the detachable design of the teaching aid facilitates storage and portability, making it suitable for various scenarios such as classroom teaching and science popularization activities, thus enhancing its practical value.

[0033] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figure 1-6 The detailed description of the embodiments will clearly demonstrate this. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0034] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0035] I. Assembly Steps

[0036] Parts Pre-processing: Carefully remove the following components from the main assembly: Cross Clip 1, Saturn Array 2, Mars Array 3, Pointer Array 4, Venus Array 5, and Four Star Array 6. All parts have their edges pre-polished to remove burrs and ensure safe assembly.

[0037] Layered assembly: First, fix the cross buckle 1 to the operating platform as the assembly benchmark.

[0038] Stack the disks in sequence: Align the center of the largest Saturn disk 2 with the cross clip 1 and insert it to fix it; then stack the Mars disk 3, pointer disk 4, Venus disk 5 in sequence from bottom to top, and finally install the smallest four-star disk 6, ensuring that the center hole of all disks is completely aligned with the cross clip 1 to form a stable stacked structure.

[0039] II. Usage Method

[0040] Predicting the dynamic position of Venus: Align the triangle 51 on the Venus disk 5 with the triangle 61 on the target year on the four-star disk 6 (e.g., 2007).

[0041] By observing the correspondence between the scales of Venus Plate 5 and the Four Planets Plate 6, the position and state of Venus at different times of the year can be directly read (such as the time of appearance as the Morning Star or Evening Star), intuitively demonstrating the dynamic movement pattern of Venus.

[0042] Mars position prediction: Determine the target date (e.g., February 1, 2002), and align the specified date mark 31 on the Mars disk 3 with the year mark 21 (2002) on the inner circle of the Saturn disk 2.

[0043] Rotate dial 4 so that its scale line 41 aligns with the "Earth" scale line on the Venus disk 5, and simultaneously aligns with the target date scale on the four-star disk 6.

[0044] Continue rotating dial 4 until the mark 41 is parallel to the direction line from the "Earth+" mark to the "Mars+" mark. At this point, you can read the zodiac constellation (such as Pisces) where Mars is located by the position of the mark 41 on the Mars disk 3 or the Saturn disk 2.

[0045] Jupiter and Saturn position prediction: Rotate pointer 4 so that scale line 41 points to the year scale 21 corresponding to Jupiter or Saturn on the Jupiter-Saturn disk 2 (e.g., 2002).

[0046] Using the indicator lines on Saturn Chart 2, determine the specific position of Jupiter or Saturn in the zodiac constellation (such as Pisces or Taurus). This operation, through the linkage between pointer chart 4 and the scale of Saturn Chart 2, visually displays the annual positional changes of Jupiter and Saturn.

[0047] III. Technology Optimization and Expansion

[0048] Scale precision design: The scale markings on each dial (such as year scale 21, date scale 31, triangular scale 51, etc.) are laser etched to ensure clear and precise scales and improve the accuracy of position prediction.

[0049] Material selection: The parts and components are made of environmentally friendly ABS engineering plastic, which is lightweight, high-strength, and wear-resistant, ensuring the durability of the teaching aids while reducing the difficulty of assembly.

[0050] Adaptable to teaching scenarios: The modular structure and intuitive scale operation provide an interactive tool for astronomy teaching. Teachers can explain the principles of celestial motion by assembling the parts step by step, while students can deepen their understanding through hands-on operation. It is suitable for various scenarios such as classroom demonstrations and science exhibitions.

[0051] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
