Description

Technical Field

[0001] The present utility model relates to the technical field of teaching aids, and particularly to a new sundial teaching aid. Background Art

[0002] A sundial teaching aid is a teaching and demonstration device that simulates the working principle of a traditional sundial and is used to display this ancient timekeeping tool that uses sunlight projection to show time. It usually consists of a dial, a pointer, and a support structure. Its working principle is that sunlight shines on the pointer, causing the shadow to be projected onto the dial, indicating different times as the position of the sun changes. This teaching aid has various teaching uses, including demonstrating the principle of the Earth's movement, explaining the relationship between the sun's movement and time, introducing ancient timekeeping methods, and explaining the influence of geographical latitude on the design of sundials. There are various types of sundial teaching aids, such as horizontal sundials, vertical sundials, equatorial sundials, and adjustable sundials, which have teaching advantages such as being intuitive, interdisciplinary, and reflecting historical significance. When using it, it should be noted to operate outdoors on sunny days, correctly position and adjust the direction, and it can also be used in conjunction with maps and compasses. Modern versions include digital, portable, and interactive sundials, which can meet different teaching needs. In addition, extended activities such as making simple sundials, design competitions, and historical research can also be carried out. The sundial teaching aid is not only an interesting teaching tool but also a bridge connecting ancient wisdom and modern technology, which can stimulate students' interest in time, astronomy, and geography, cultivate observation and practical skills, make abstract concepts concrete and tangible, and thus improve learning effects.

[0003] The application number is CN200820230904.3. This new sundial teaching aid includes a dial plate and a pointer. A circular hole is provided at the center of the dial plate, and the lower end of the pointer is matched with the circular hole and vertically inserted into the circular hole. The S-pole marking line is engraved on the dial plate surface, and the reverse extension line of the S-pole marking line is engraved with the 12 o'clock marking line. Starting from the 12 o'clock marking line and passing through the center of the circle every 15 degrees to the right, a total of 7 marking lines are engraved, which respectively represent 1 to 7 o'clock from the 12 o'clock marking line to the right. Starting from the 12 o'clock marking line and passing through the center of the circle every 15 degrees to the left, a total of 7 marking lines are engraved, which respectively represent 5 to 11 o'clock from left to the 12 o'clock marking line. With the above technical solution, the product has a low cost, is easy to assemble, and has a clear principle. It is suitable for classroom teaching and is convenient for students to understand and master the sundial timekeeping principle.

[0004] In the above technology, the layout of measurement data is carried out within a single plane, so that multiple functions are integrated into one. However, the specific practical ways of many experiments and measurement data require adjustment of the measurement angle. Although the structure of a single plane is convenient to use and carry, it cannot vividly perform measurements and cannot improve the teaching quality and the effect of teacher-student interaction.

Specific implementation manners

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] As Figures 1 - 10 shown, a new type of sundial teaching aid includes: a first teaching aid component 1, a connecting shaft rod 2 is arranged at the bottom end of the first teaching aid component 1, a ball rod 6 is arranged on one side of the bottom end of the first teaching aid component 1, and an auxiliary structure 3 is arranged at the bottom end of the connecting shaft rod 2;

[0031] A base 4 is arranged directly below the bottom end of the first teaching aid component 1, a second teaching aid component 5 is arranged on one side of the top end of the base 4, an embedded frame 7 is arranged on the outer side of the second teaching aid component 5, and a position movement structure 8 is arranged on one side of the top surface of the base 4.

[0032] As Figures 1 - 10 shown, a new type of sundial teaching aid, the auxiliary structure 3 includes a cloud base 301, an embedded table 302, a ball seat shell 303 and a fiber frame 304. The cloud base 301 is arranged at the top end of the base 4, a fiber frame 304 is clamped at the lower end of the outer side of the cloud base 301, an embedded table 302 is vertically arranged inside the cloud base 301, a ball seat shell 303 is vertically arranged inside the embedded table 302, a vertical groove is annularly opened at the upper end of the outer side of the ball seat shell 303, and the outer shapes of the embedded table 302 and the cloud base 301 are curved table shapes:

[0033] For the rest, since the cloud base 301, the embedded base 302, the ball socket housing 303 and the connecting shaft rod 2 are superposed and engaged with each other, the cloud base 301 rotates in cooperation with the embedded base 302, and the ball socket housing 303 also rotates in cooperation with the embedded base 302. At the same time, notches are provided around the top of the ball socket housing 303. When the connecting shaft rod 2 is flipped and rotated, the vertical part at the upper end of the connecting shaft rod 2 will not get stuck inside the ball socket housing 303. After the user removes the embedded base 302, the assembled components of the connecting shaft rod 2 and the ball socket housing 303 can also be placed inside the cloud base 301. Then, the ball socket housing 303 can make tilting rotations and other activities inside the cloud base 301, thereby expanding the placement range of the first teaching aid component 1.

[0034] The following effects and novel technologies are brought:

[0035] Multi-layer rotating structure: The cloud base 301, the embedded base 302, and the ball socket housing 303 form a multi-layer nested structure, and each layer can rotate independently. This design allows the sundial to be adjusted on multiple planes, increasing the flexibility of the device.

[0036] Spherical joint design: The spherical part at the bottom end of the connecting shaft rod 2 and the ball socket housing 303 form a spherical joint. This design allows the sundial to be flipped at multiple angles, greatly increasing the degree of freedom of adjustment.

[0037] Detachability: Each component can be disassembled and re-assembled. For example, the embedded base 302 can be taken out to change the assembly method. This design increases the versatility and adaptability of the teaching aid.

[0038] Stability design: The shape matching design between the embedded base 302 and the cloud base 301 ensures the stability during rotation, and the use of the fiber frame 304 further enhances the stability of the overall structure.

[0039] Expansion function: The placement range of the first teaching aid component 1 can be expanded by changing the assembly method, such as directly placing the ball socket housing 303 into the cloud base 301.

[0040] Precise adjustment: The combination of the multi-layer rotating structure and the spherical joint allows for precise angle adjustment, which is beneficial for simulating sundial settings at different geographical locations.

[0041] Teaching interactivity: The detachable and multi-angle adjustment design increases the teaching interactivity, and students can operate and adjust the device in person.

[0042] Simulation diversity: This design allows for simulating sundial effects at different latitudes and different times, increasing the diversity of teaching.

[0043] Structural innovation: The curved table shape design and the multi-layer nested structure are the innovation points of this teaching aid, which are different from the designs of traditional sundials.

[0044] Convenient for storage and transportation: The detachable design enables the teaching aids to be compactly stored when not in use, facilitating storage and transportation.

[0045] As Figures 1 - 10 shown, a new type of sundial teaching aid, the position movement structure 8 includes a horizontal groove 801 and a bottom block 802. A bottom block 802 is provided at the middle of one side of the top end of the base 4, and a horizontal groove 801 is provided at the middle of the bottom end of the second teaching aid component 5. A sliding structure is formed between the horizontal groove 801 and the bottom block 802:

[0046] For the rest, since the horizontal groove 801 at the bottom end of the second teaching aid component 5 can cooperate with the bottom block 802 for sliding movement, the second teaching aid component 5 can approach the edge of the first teaching aid component 1 at any time. After the second teaching aid component 5 approaches the outside of the first teaching aid component 1, the first teaching aid component 1 rotates through the cooperation of the connecting shaft rod 2, so that the outside of the ball rod 6 passes through the arc groove opened on the outside of the second teaching aid component 5. At the same time, after the inlay frame 7 is stuck in the arc groove on the outer surface of the second teaching aid component 5, the ball rod 6 will be stuck inside the inlay frame 7. At this time, the first teaching aid component 1 will not continue to turn and rotate. When the inlay frame 7 is removed and the horizontal groove 801 helps the second teaching aid component 5 move to the outside of the base 4, the first teaching aid component 1 will continue to adjust the use angle.

[0047] Among them, the following effects and novel technologies are brought:

[0048] Enhanced adjustability: The sliding structure formed by the horizontal groove 801 and the bottom block 802 allows the second teaching aid component 5 to move horizontally on the base 4. This design increases the adjustability of the teaching tool and can change the relative position between the two teaching tool components according to needs.

[0049] Linkage mechanism: Through the cooperation of the ball rod 6, the arc groove and the inlay frame 7, the linkage between the first teaching aid component 1 and the second teaching aid component 5 is realized. This linkage mechanism enables the two components to work together, increasing the complexity and diversity of teaching demonstrations.

[0050] Lockable function: The inlay frame 7 can lock the ball rod 6, thereby restricting the movement of the first teaching aid component 1. This design allows the position of the teaching tool component to be fixed when needed, which is beneficial for precise observation or long-term demonstration.

[0051] Flexibility: By removing the inlay frame 7 and moving the second teaching aid component 5, the linkage between the two components can be easily released. This flexibility enables the teaching tool components to quickly switch between the linkage and independent movement modes.

[0052] Precise positioning: The sliding structure of the horizontal groove 801 and the bottom block 802 allows the second teaching aid component 5 to perform precise horizontal positioning, which helps with precise measurement and demonstration, especially when simulating different latitudes or times.

[0053] Interactive teaching: The adjustable and detachable design increases the interactivity of the teaching tool components. Students can operate and adjust them in person, which helps to enhance students' practical ability and understanding of the sundial principle.

[0054] Simulation diversity: By adjusting the relative positions of the two teaching tool components, the sundial effects at different geographical locations or times can be simulated, which increases the teaching value of the teaching aid and enables it to demonstrate more astronomical and geographical concepts.

[0055] Structural innovation: The sliding structure of the horizontal groove 801 and the bottom block 802, as well as the linkage mechanism of the ball rod 6, the arc groove and the embedding frame 7, are the innovative points of this teaching aid. This design is different from traditional sundials and increases the functionality and adaptability of the teaching aid.

[0056] Safety: The lockable design increases the safety of using the teaching tool components and prevents accidental movement or adjustment.

[0057] Improvement of teaching effect: By allowing precise adjustment and linkage operation, this design helps to demonstrate the sundial principle more intuitively and deeply, and can better explain complex concepts such as the movement of the sun, the rotation and revolution of the earth.

[0058] Working principle: When using this new type of sundial teaching aid, first place the cloud base 301 in the rectangular groove at the top of the base 4, then sleeve the fiber frame 304 on the lower end outside the cloud base 301. At this time, the cloud base 301 will be positioned at the top of the base 4. Then place the embedded platform 302 inside the cloud base 301, and the ball seat shell 303 is also snapped into the inside of the embedded platform 302. The user aligns the connecting shaft rod 2 at the bottom of the first teaching tool component 1 with the ball seat shell 303. After the connecting shaft rod 2 and the ball seat shell 303 are assembled, the user can rotate the first teaching tool component 1 at multiple angles. The connecting shaft rod 2 at the bottom of the first teaching tool component 1 will rotate inside the ball seat shell 303, and the embedded platform 302 can also rotate inside the cloud base 301. Thus, the first teaching tool component 1 can perform activities such as planar rotation and planar flipping. Then the user aligns the horizontal groove 801 at the bottom of the second teaching tool component 5 with the bottom block 802. After the horizontal groove 801 is embedded in the inside of the bottom block 802, move the second teaching tool component 5. At this time, the horizontal groove 801 cooperates with the bottom block 802 to move. When the first teaching tool component 1 is driven to rotate by the connecting shaft rod 2, the ball rod 6 at the bottom of the first teaching tool component 1 passes through the arc groove on the surface of the second teaching tool component 5. At this time, the staff snaps the embedding frame 7 into the arc groove on the surface of the second teaching tool component 5 and the outside of the ball rod 6. At this time, the second teaching tool component 5 and the first teaching tool component 1 will be used in linkage. This is the working principle of this new type of sundial teaching aid.

[0059] The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better illustrate the principles of the present utility model and its practical applications, and to enable those of ordinary skill in the art to understand the present utility model and design various embodiments with various modifications suitable for specific purposes.
