Description

Technical Field

[0001] This utility model relates to the field of magnetic structure technology, specifically a magnetic structure for vocabulary cards. Background Technology

[0002] The magnetic structure of vocabulary cards refers to a design that allows vocabulary cards to be magnetically attached to a specific surface, such as a magnetic whiteboard or any metal surface. This structure facilitates the display and organization of vocabulary cards.

[0003] However, the existing magnetic structure for vocabulary cards has the following drawbacks:

[0004] (1) The existing magnetic structure of vocabulary cards is not easy to disassemble. When the magnetic force of the magnetic block (5) weakens during use, it is necessary to replace the magnetic block in time. The replacement process of the magnetic block (5) of the traditional magnetic structure is more troublesome, which makes the replacement process inconvenient.

[0005] (2) The existing magnetic structure of vocabulary cards has a weak function of protecting the cards from damage. When using them, the surface of the cards is prone to aging and damage after a long period of use and needs to be replaced. However, the traditional magnetic structure usually means that the cards are simply thrown away for replacement, which increases costs and reduces the lifespan of the cards. Utility Model Content

[0006] The purpose of this invention is to provide a magnetic structure for vocabulary cards to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a magnetic structure for vocabulary cards, comprising a fixed frame, a limiting groove on one side of the fixed frame, a limiting slider slidably connected inside the limiting groove, a limiting block fixedly connected to one side of the limiting slider, a magnetic block fixedly connected to the other side of the limiting slider, a rotating shaft fixedly connected to the bottom of the fixed frame away from the magnetic block, a cover plate provided on the outer surface of the rotating shaft, a connecting block fixedly connected to one side of the cover plate, an mounting block fixedly connected to the outer surface of the connecting block, and a connecting slot hole on the side of the fixed frame near the cover plate.

[0008] Optionally, the connecting slot has an internal mounting groove, and the mounting block fits into the mounting groove. When the mounting block is inserted into the mounting groove, the mounting groove limits the mounting block, fixing its position inside the mounting groove.

[0009] Optionally, a limiting slot is provided inside the limiting slide groove, and the limiting block fits into the limiting slot. When the limiting block is inserted into the limiting slot, the limiting slot restricts the surface of the limiting block to ensure that the position of the limiting block does not shift.

[0010] Optionally, the top of the cover plate is provided with a fixing groove, and a trapezoidal block is fixedly connected inside the fixing groove. The trapezoidal block is fixed by the fixing groove, and pulling the trapezoidal block can more easily flip the cover plate open.

[0011] Optionally, a rectangular slot is provided on one side of the cover plate, and a viewing window is fixedly connected inside the rectangular slot. The viewing window is fixed by the rectangular slot, and the card can be viewed intuitively through the viewing window.

[0012] Optionally, the inner bottom wall of the fixing frame is provided with a placement groove, and the card body is disposed inside the placement groove. The placement groove can limit the bottom of the card body, so that the card body can be fixed to the inner bottom wall of the fixing frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The magnetic structure of this vocabulary card, through the setting of a limiting groove, a limiting slider, a limiting block, and a magnetic block, allows the limiting slider to slide inside the limiting groove during use. Simultaneously, the limiting groove limits the limiting slider. When the limiting slider slides a certain distance, the limiting block engages with a slot inside the limiting groove, fixing the limiting slider and the magnetic block in place. This completes the installation of the magnetic block. The magnetic block has a certain magnetic force, enabling it to stably adhere to a magnetic surface and preventing it from easily falling off. Sliding the limiting slider in the opposite direction allows the magnetic block to be detached from the device, thus improving the ease of use of the device.

[0015] 2. This vocabulary card magnetic structure, through the setting of a fixed frame, rotating shaft, cover plate, connecting block, mounting block, and connecting slot, allows for easy card placement. When the cover plate is flipped to a certain angle, the connecting block engages in the connecting slot. Simultaneously, the rotating shaft limits the cover plate's position. Applying pressure to the cover plate causes the mounting block to engage in the slot within the connecting slot, securing the cover plate and completing the card replacement and placement. This protects the card surface, extending its lifespan and preventing premature aging and damage that necessitates replacement. Traditional magnetic structures typically require discarding the card for replacement, increasing costs and reducing its lifespan. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution: a magnetic structure for vocabulary cards, including a fixed frame 1. A limiting groove 2 is formed on one side of the fixed frame 1. A limiting slider 3 is slidably connected inside the limiting groove 2. A limiting block 4 is fixedly connected to one side of the limiting slider 3. A magnetic block 5 is fixedly connected to the other side of the limiting slider 3. A rotating shaft 6 is fixedly connected to the bottom of the fixed frame 1 on the side away from the magnetic block 5. A cover plate 7 is provided on the outer surface of the rotating shaft 6. A connecting block 8 is fixedly connected to one side of the cover plate 7. An installation block 9 is fixedly connected to the outer surface of the connecting block 8. A connecting slot 10 is formed on the side of the fixed frame 1 closest to the cover plate 7. The limiting slider 3 slides inside the limiting groove 2, while the limiting groove 2 limits the limiting slider 3. When the limiting slider 3 slides to a certain distance, the limiting block 4 will engage in the slot inside the limiting slide groove 2, fixing the limiting slider 3 and the magnetic block 5, thus completing the installation of the magnetic block 5. The magnetic block 5 has a certain magnetic force and can stably adhere to the magnetic surface, making it difficult to fall off. By sliding the limiting slider 3 in the opposite direction, the magnetic block 5 can be disassembled and removed from the device. After placing the card inside the device, when the cover plate 7 is flipped to a certain angle, the connecting block 8 will engage in the connecting slot 10. At the same time, the rotating shaft 6 will rotate to limit the cover plate 7. After applying a certain force to press the cover plate 7, the mounting block 9 will engage in the slot inside the connecting slot 10, fixing the mounting block 9 and the cover plate 7, thus completing the replacement and placement of the card and protecting the surface of the card.

[0023] The connecting slot 10 has an installation slot 11 inside. The installation block 9 fits into the installation slot 11. When the installation block 9 is inserted into the installation slot 11, the installation slot 11 limits the installation block 9 and fixes the position of the installation block 9 inside the installation slot 11.

[0024] The limiting groove 2 has a limiting slot 12 inside, and the limiting block 4 fits into the limiting slot 12. When the limiting block 4 is inserted into the limiting slot 12, the limiting slot 12 restricts the surface of the limiting block 4 to ensure that the position of the limiting block 4 will not shift.

[0025] The top of the cover plate 7 is provided with a fixing groove, and a trapezoidal block 13 is fixedly connected inside the fixing groove. The trapezoidal block 13 is fixed by the fixing groove, and the cover plate 7 can be flipped open more easily by pulling the trapezoidal block 13.

[0026] A rectangular slot is provided on one side of the cover plate 7. A viewing window 14 is fixedly connected inside the rectangular slot. The viewing window 14 is fixed by the rectangular slot and can be viewed intuitively through the viewing window 14.

[0027] The inner bottom wall of the fixed frame 1 is provided with a placement groove 15, and the card body 16 is provided inside the placement groove 15. The placement groove 15 can limit the bottom of the card body 16, so that the card body 16 can be fixed to the inner bottom wall of the fixed frame 1.

[0028] In this invention, the working steps of the device are as follows:

[0029] First step: Slide the limiting slider 3 inside the limiting groove 2. At the same time, the limiting groove 2 limits the limiting slider 3. When the limiting slider 3 slides to a certain distance, the limiting block 4 will be inserted into the slot inside the limiting groove 2, fixing the limiting slider 3 and the magnetic block 5. This completes the installation of the magnetic block 5. The magnetic block 5 has a certain magnetic force and can be stably attracted to the magnetic surface. It is not easy to fall off. Slide the limiting slider 3 in the opposite direction to remove the magnetic block 5 from the device. After placing the card inside the device, when the cover plate 7 is flipped to a certain angle, the connecting block 8 will be inserted into the connecting slot 10. At the same time, the rotating shaft 6 rotates to limit the cover plate 7. After applying a certain force to press the cover plate 7, the mounting block 9 will be inserted into the slot inside the connecting slot 10, fixing the mounting block 9 and the cover plate 7. This completes the replacement and placement of the card, thus protecting the surface of the card.

[0030] Second step: When the mounting block 9 is inserted into the mounting slot 11, the mounting slot 11 limits the mounting block 9, fixing the position of the mounting block 9 inside the mounting slot 11. When the limiting block 4 is inserted into the limiting slot 12, the limiting slot 12 restricts the surface of the limiting block 4 to ensure that the position of the limiting block 4 will not shift. The trapezoidal block 13 is fixed by the setting of the fixing slot. Pulling the trapezoidal block 13 can more easily flip and open the cover plate 7.

[0031] The third step: The viewing window 14 is fixed by setting the rectangular slot. The viewing window 14 allows for a direct view of the card. The placement slot 15 limits the bottom of the card body 16, so that the card body 16 can be fixed to the inner bottom wall of the fixing frame 1.
