Description

Technical Field

[0001] This utility model relates to the field of educational equipment technology, and in particular to a portable folding teaching board for educational use. Background Technology

[0002] In the field of education, whiteboards are an indispensable tool for teachers, used to display teaching content, write key points, and so on. Whether in school classrooms, training institutions, or corporate training rooms, whiteboards play an important role. They help teachers convey knowledge to students more intuitively, enhancing the interactivity and effectiveness of teaching. In traditional classroom teaching, teachers guide students to understand and master course content by writing on the whiteboard and drawing charts. In group discussions or impromptu teaching activities, whiteboards also provide a convenient platform for teachers and students to communicate and display their knowledge, promoting the dissemination and exchange of knowledge.

[0003] Existing teaching boards typically consist of a fixed rigid board surface, such as a whiteboard or blackboard, and a mounting bracket. The board surface is fixed to the classroom wall or bracket by bolts, welding, or hooks to maintain stability. The bracket usually has a certain height adjustment function, which can meet the usage needs of teachers of different heights by adjusting screws or hydraulic devices.

[0004] Existing teaching boards have significant drawbacks. Regarding folding and storage, their fixed structure prevents them from being folded, resulting in them occupying considerable space when not in use. For example, in small training rooms or temporary teaching locations with limited space, the fixed size and non-foldability of the teaching boards pose challenges to space utilization and affect other functional uses of the space. In terms of installation and disassembly, existing methods are complex and cumbersome, requiring specialized tools and installation skills. When the teaching board needs to be relocated or the classroom needs renovation, the disassembly process is time-consuming and labor-intensive. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a portable folding teaching board for education and teaching, which aims to improve the problems of existing structures that cannot be folded, occupy a lot of space in places with limited space and affect the function of the site, and are complicated to install and disassemble, requiring professional tools and skills, and taking time and effort to disassemble when changing the location or renovating.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable folding teaching board for education and teaching, comprising a magnetic blackboard, a hinged page fixedly connected to one side of the outer wall of the magnetic blackboard, a magnetic folding plate fixedly connected to one side of the hinged page, a sliding groove plate fixedly connected to the outer wall of the magnetic blackboard, a limiting component provided inside the sliding groove plate, the limiting component including an insert plate, the outer wall of the insert plate slidably connected to the inside of the sliding groove plate, a rack plate fixedly connected to one side of the insert plate, a gear rotatably connected inside the sliding groove plate, a handwheel fixedly connected to one end of the gear, a limiting plate fixedly connected to one side of the outer wall of the magnetic folding plate, the outer wall of the insert plate slidably connected to the inside of the limiting plate, a connecting seat fixedly connected to the outer wall of the magnetic blackboard, a pressure rod slidably connected inside the connecting seat, a spring sleeved on the outer wall of the pressure rod, and a positioning component provided on the outer wall of the pressure rod.

[0007] Furthermore, the positioning component includes a positioning plate, the outer wall of the pressure rod is slidably connected to the inside of the positioning plate, and the positioning plate is provided with a slot inside.

[0008] Furthermore, a pin is fixedly connected to the outer wall of the pressure rod, the outer wall of the pin is slidably connected to the inside of the slot, a limit groove is provided on the outside of the connecting seat, a connecting block is fixedly connected to the outer wall of the pressure rod, the outer wall of the connecting block is slidably connected to the inside of the limit groove, and the outer wall of the positioning plate is fixedly connected to the inside of the fixing plate.

[0009] Furthermore, a telescopic rod is fixedly connected to the lower surface of the fixed plate, a steel ball is slidably connected inside the telescopic rod, a spring is provided on one side of the steel ball, a sliding sleeve is slidably connected to the outer wall of the telescopic rod, a limit hole is provided on the outside of the sliding sleeve, and a movable plate is fixedly connected to one end of the limit hole.

[0010] Furthermore, the gear meshes with the rack plate, and one side of the outer wall of the rack plate is slidably connected inside the slide groove plate.

[0011] Furthermore, one end of the spring is fixedly connected to the lower surface of the pressure rod, and the other end of the spring is fixedly connected to the inside of the connecting seat.

[0013] Furthermore, the outer wall of the steel ball is slidably connected inside the limiting hole.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, when folding, the operator can rotate the hinge to fold the magnetic folding board relative to the magnetic blackboard, reducing space occupation and facilitating storage and transportation in small spaces. After unfolding the magnetic folding board, rotating the handwheel drives the gear, which in turn meshes with the rack plate to drive the insert plate to slide on the slide plate and insert into the limiting plate, stabilizing and limiting the position to ensure that the teaching board is flat and free from shaking or displacement during use. When installing the magnetic blackboard, pressing down the pressure rod compresses the spring to insert the pin into the slot, and rotating the connecting block engages with the limiting slot, achieving quick installation. When disassembling, moving the connecting block away from the limiting slot causes the pin to disengage from the slot under the reset action of the spring, completing the disassembly. This operation is simple and requires no professional tools, saving time and increasing convenience, and is suitable for frequent changes in location or renovation scenarios.

[0016] 2. In this utility model, when the height of the teaching board needs to be adjusted, the operator can pull the fixed plate up or down. The fixed plate drives the telescopic rod to slide relative to the sliding sleeve. During the sliding process, the steel ball will be engaged or disengaged in the limiting hole at different positions under the elastic force of the second spring, thereby realizing the height adjustment of the teaching board. This height adjustment method is simple to operate and can quickly meet the needs of teachers of different heights, improving the applicability and comfort of the teaching board. At the same time, due to the reasonable structural design, it can remain stable during the adjustment process and will not shake or slip off on its own, ensuring the smooth progress of the teaching process.

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.

[0026] Reference Figure 1 - Figure 5This utility model provides an embodiment of a portable folding teaching board for educational purposes, including a magnetic blackboard 1. The surface coating of the magnetic blackboard 1 is a specially made black magnetic material used in teaching to attract and retain a folding board 2. A hinge 3 is fixedly connected to one side of the outer wall of the magnetic blackboard 1, and the magnetic folding board 2 is fixedly connected to one side of the hinge 3. The hinge 3 allows the magnetic blackboard 1 and the magnetic folding board 2 to fold together and then be attracted and fixed by their magnetism. A sliding plate 5 is fixedly connected to the outer wall of the magnetic blackboard 1. During the sliding process, the insertion plate 6, relying on its high-precision cooperation with the sliding plate 5 and its own guiding structure, gradually approaches and accurately inserts its front end into the slot inside the limiting plate 4. The sliding plate 5 is provided with a limiting component, which includes the insertion plate 6. When the insertion plate 6 is fully inserted... After the magnetic folding plate 2 is fully inserted into the slot of the limiting plate 4, it achieves stable positioning, ensuring the flatness and stability of the teaching board during use. The outer wall of the insert plate 6 is slidably connected to the inside of the slide plate 5. A rack plate 7 is fixedly connected to one side of the insert plate 6. A gear 8 is rotatably connected inside the slide plate 5. The precise meshing of the gear 8 and the rack plate 7 converts the rotational motion into linear motion, allowing the insert plate 6 to slide smoothly within the slide plate 5. A handwheel 9 is fixedly connected to one end of the gear 8. The handwheel 9 drives the gear 8 to rotate via a flat key. A limiting plate 4 is fixedly connected to one side of the outer wall of the magnetic folding plate 2. The outer wall of the insert plate 6 is slidably connected to the inside of the limiting plate 4. A connecting seat 10 is fixedly connected to the outer wall of the magnetic blackboard 1. A pressure rod 11 is slidably connected inside the connecting seat 10. First, the pressure rod 11 is pressed down. During this process, the pressure rod 11... Overcoming the elastic force of spring 13, the pin 15 moves downward, allowing it to smoothly insert into the slot 17. Spring 13 is sleeved on the outer wall of the pressure rod 11, and a positioning component is provided on the outer wall of the pressure rod 11. The positioning component includes a positioning plate 16, and the outer wall of the pressure rod 11 is slidably connected to the inside of the positioning plate 16. The slot 17 is provided inside the positioning plate 16. By simply moving the connecting block 12 to disengage it from the limiting groove 14, the pin 15 will automatically disengage from the slot 17 under the restoring elastic force of spring 13, thus completing the disassembly of the magnetic blackboard 1. Gear 8 meshes with rack plate 7, and one side of the outer wall of rack plate 7 is slidably connected to the inside of slide plate 5. One end of spring 13 is fixedly connected to the lower surface of pressure rod 11, and the other end of spring 13 is fixedly connected to the inside of connecting seat 10.

[0027] Reference Figure 1 , Figure 5 and Figure 6A pin 15 is fixedly connected to the outer wall of the pressure rod 11. The outer wall of the pin 15 is slidably connected inside the slot 17. When disassembling the magnetic blackboard 1, the operator lifts the pressure rod 11 again to disengage the pin 15 from the slot 17, and then carefully removes the magnetic blackboard 1 from its installation position. A limiting groove 14 is provided on the outside of the connecting seat 10. The limiting groove 14 limits the connecting block 12. The connecting block 12 is fixedly connected to the outer wall of the pressure rod 11. When the connecting block 12 is rotated, it precisely engages with the limiting groove 14 during rotation, thus realizing the magnetic blackboard 1. For quick installation, the outer wall of the connecting block 12 is slidably connected to the inside of the limiting groove 14, and the outer wall of the positioning plate 16 is fixedly connected to the inside of the fixing plate 24. The operator holds the fixing plate 24 and applies appropriate force upward or downward according to the required height direction, so that the fixing plate 24 drives the telescopic rod 18 to telescopically move relative to the sliding sleeve 21. The telescopic rod 18 is fixedly connected to the lower surface of the fixing plate 24, and a steel ball 20 is slidably connected inside the telescopic rod 18. Under the elastic force of the spring 19, the steel ball 20 will move at different positions. The ball 20 can be inserted into or removed from the positioning hole 22. A second spring 19 is provided on one side of the steel ball 20. A sliding sleeve 21 is slidably connected to the outer wall of the telescopic rod 18. A limiting hole 22 is provided on the outside of the sliding sleeve 21. When the steel ball 20 is inserted into the new limiting hole 22, the height of the teaching board is fixed at the corresponding position. A movable plate 23 is fixedly connected to one end of the limiting hole 22. One end of the second spring 19 is fixedly connected to the inside of the telescopic rod 18, and the other end of the second spring 19 is fixedly connected to one side of the outer wall of the steel ball 20. The outer wall of the steel ball 20 is slidably connected to the inside of the limiting hole 22.

[0028] Working principle: When the teaching board needs to be folded, the operator holds the edge of the magnetic folding board 2 and gently rotates the hinge 3. The rotating shaft of the hinge 3 rotates flexibly under the support of the bearing or bushing, causing the magnetic folding board 2 to gradually fold relative to the magnetic blackboard 1. After folding, the volume of the teaching board is greatly reduced, making it convenient for storage or transportation in places with limited space. When the teaching board needs to be used, the operator holds the edge of the magnetic folding board 2 again and rotates the hinge 3 in the opposite direction to unfold the magnetic folding board 2 so that it is on the same plane as the magnetic blackboard 1. After the magnetic folding board 2 is unfolded, the operator rotates the handwheel 9. The rotation of gear 8 is converted into linear motion of rack plate 7, which in turn causes insert plate 6 to slide smoothly within slide plate 5. During the sliding process, the front end of insert plate 6 gradually approaches and accurately inserts into the slot inside limiting plate 4, achieving stable positioning of magnetic folding plate 2 and ensuring the flatness and stability of the teaching board during use. During the installation of magnetic blackboard 1, the operator first presses down on the pressure rod 11. During this process, the pressure rod 11 moves downward against the elastic force of spring 13, allowing pin 15 to smoothly insert into slot 17. Then, the connecting block 12 is rotated. During the rotation of the connecting block 12... The magnetic blackboard 1 is quickly installed by precisely inserting it into the limiting slot 14. During disassembly, simply move the connecting block 12 to disengage it from the limiting slot 14. Then, under the restoring force of the spring 13, the pin 15 automatically disengages from the slot 17, thus completing the disassembly of the magnetic blackboard 1. The entire installation and disassembly process is simple and easy, requiring no special tools, greatly saving time and significantly improving ease of use. It is especially suitable for scenarios requiring frequent changes in the position of the teaching board or classroom renovations. When adjusting the height of the teaching board, the operation... Personnel hold the fixed plate 24 and slide it up or down, causing the telescopic rod 18 to extend or retract relative to the sliding sleeve 21. During the extension and retraction, the steel ball 20, under the elastic force of the spring 19, will be inserted into or removed from the limiting hole 22 at different positions. When the steel ball 20 is inserted into a new limiting hole 22, the height of the teaching board is fixed at the corresponding position. When adjusting the height, attention should be paid to observing the change in the height of the teaching board to ensure that the required height is reached. This height adjustment method is simple to operate and can quickly meet the usage needs of teachers of different heights, improving the applicability and comfort of the teaching board.
