Abstract
Description
Technical Field
[0001] This utility model relates to the field of teaching card technology, specifically a magnetic structure for vocabulary cards. Background Technology
[0002] Magnetic vocabulary flashcards refer to a design that allows them to be easily attached to a medium for viewing and learning. Some flashcards have small magnets on the back or in a corner. These magnets allow the cards to adhere to magnetic surfaces (such as magnetic whiteboards, refrigerator doors, etc.), making it convenient for users to view and review them at any time.
[0003] However, the existing magnetic structure for vocabulary cards has the following drawbacks:
[0004] (1) The existing magnetic structure of vocabulary cards is not very convenient for collecting and carrying vocabulary cards. Since there are many words and the number of words that can be recorded on a single card is limited, traditional vocabulary cards tend to pile up when carried, making it difficult and time-consuming to find the corresponding vocabulary cards later.
[0005] (2) The existing magnetic structure of vocabulary cards has a weak function of facilitating the assembly and disassembly of the magnetic structure. Since the vocabulary cards do not need to use the magnetic structure in certain usage scenarios, and the magnetic structure in traditional vocabulary cards is difficult to disassemble, the device has limitations and the number of usable occasions is reduced. 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 attraction structure for vocabulary cards, comprising a first limiting ring, a second limiting ring rotatably connected to one end of the first limiting ring, a limiting block fixedly connected to the bottom side of one side of the second limiting ring, a circular slot formed on one side of the surface of the first limiting ring, a card body slidably connected to the outer surface of the first limiting ring, a limiting groove formed on one side of the card body, a limiting slider slidably connected inside the limiting groove, a limiting card block fixedly connected to the side of the limiting slider, and a magnetic attraction block fixedly connected to one side of the surface of the limiting slider.
[0008] 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 block applies a limiting force to the limiting slot, thereby fixing the position of the limiting block and thus fixing the position of the magnetic block.
[0009] Optionally, a suction cup is fixedly connected to the side of the card body near the magnetic block. When there is no magnetic material on the surface to be attracted, the magnetic block can be removed, and the card body can be pressed to make the suction cup adhere to the surface to be attracted, thereby fixing the card body in place.
[0010] Optionally, a rectangular slot is provided on the top side of the card body. The rectangular slot fits into the first limiting ring. When the card body slides on the surface of the first limiting ring, the rectangular slot limits the position of the card body to prevent the card body from falling.
[0011] Optionally, the magnetic block is made of rare-earth permanent magnets, and the use of rare-earth permanent magnets can improve the overall performance of the magnetic structure.
[0012] Optionally, the limiting block is fitted with the circular slot. When the first limiting ring and the second limiting ring are fitted together, the limiting block is inserted into the circular slot. At the same time, the circular slot applies a limiting force to the limiting block, so that the first limiting ring and the second limiting ring are connected and fixed.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This vocabulary card magnetic structure, through the setting of a first limiting ring, a second limiting ring, a limiting block, and a circular slot, allows the vocabulary cards to be slid onto the surfaces of the first and second limiting rings during use. After collecting them, the second limiting ring is rotated. When one side of the second limiting ring is rotated to fit against the surface of the first limiting ring, the limiting block will engage with the interior of the circular slot. At the same time, the circular slot applies a limiting force to the limiting block, connecting the second and first limiting rings, thereby centrally storing the vocabulary cards and achieving the effect of convenient card storage.
[0015] 2. This vocabulary card magnetic suction structure, through the setting of a limiting groove, a limiting slider, a limiting block, and a magnetic block, allows for easy installation. When the limiting slider is slid into the limiting groove, the groove simultaneously limits its movement. Once the slider reaches a certain position, the limiting block engages with a slot within the limiting groove, fixing the positions of the limiting block and the magnetic block. This completes the installation of the magnetic block. Reversing the sliding of the limiting slider allows for disassembly of the magnetic block, improving the replaceability of the magnetic structure. This avoids the limitation of traditional vocabulary cards where the magnetic structure is difficult to disassemble, limiting the device's usability in specific application scenarios where the vocabulary card does not require it.

[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 first limiting ring 1, a second limiting ring 2 rotatably connected to one end of the first limiting ring 1, a limiting block 3 fixedly connected to the bottom of one side of the second limiting ring 2, a circular slot 4 formed on one side of the surface of the first limiting ring 1, a card body 5 slidably connected to the outer surface of the first limiting ring 1, a limiting groove 6 formed on one side of the card body 5, a limiting slider 7 slidably connected inside the limiting groove 6, a limiting card block 8 fixedly connected to the side of the limiting slider 7, and a magnetic block 9 fixedly connected to one side of the surface of the limiting slider 7. The vocabulary cards are slid onto the surfaces of the first limiting ring 1 and the second limiting ring 2 to collect them. Then rotate the second limiting ring 2. When one side of the second limiting ring 2 rotates to fit against the surface of the first limiting ring 1, the limiting block 3 will be inserted into the inside of the circular slot 4. At the same time, the circular slot 4 applies a limit to the limiting block 3, so that the second limiting ring 2 and the first limiting ring 1 are connected, thereby collecting the vocabulary cards. Slide the limiting slider 7 into the limiting groove 6. At the same time, the limiting groove 6 applies a limit to the limiting slider 7. When the limiting slider 7 slides to a certain position, the limiting card 8 is inserted into the slot inside the limiting groove 6, so that the positions of the limiting card 8 and the magnetic block 9 are fixed, thereby completing the installation of the magnetic block 9. The magnetic block 9 can be removed by sliding the limiting slider 7 in the opposite direction.
[0023] The limiting slide 6 has a limiting slot 10 inside. The limiting block 8 fits into the limiting slot 10. When the limiting block 8 is inserted into the limiting slot 10, the limiting block 8 applies a limit to the limiting slot 10, fixing the position of the limiting block 8, thereby fixing the position of the magnetic block 9.
[0024] A suction cup 11 is fixedly connected to the side of the card body 5 near the magnetic block 9. The magnetic block 9 can be removed, and the card body 5 can be pressed to make the suction cup 11 adhere to the surface to be attracted, thereby fixing the card body 5.
[0025] A rectangular slot 12 is provided on the top side of the card body 5. The rectangular slot 12 fits against the first limiting ring 1. When the card body 5 slides on the surface of the first limiting ring 1, the rectangular slot 12 limits the position of the card body 5 to prevent the card body 5 from falling.
[0026] The magnetic block 9 is made of rare earth permanent magnets. The use of rare earth permanent magnets can improve the overall performance of the magnetic structure.
[0027] The limiting block 3 fits into the circular slot 4, and the limiting block 3 is inserted into the circular slot 4. At the same time, the circular slot 4 applies a limiting force to the limiting block 3, so that the first limiting ring 1 and the second limiting ring 2 are connected and fixed.
[0028] In this invention, the working steps of the device are as follows:
[0029] First step: Slide the vocabulary cards onto the surfaces of the first limiting ring 1 and the second limiting ring 2. After collecting them, rotate the second limiting ring 2. When one side of the second limiting ring 2 rotates to fit against the surface of the first limiting ring 1, the limiting block 3 will be inserted into the interior of the circular slot 4. At the same time, the circular slot 4 applies a limit to the limiting block 3, connecting the second limiting ring 2 and the first limiting ring 1, thus collecting the vocabulary cards. Slide the limiting slider 7 into the limiting groove 6. At the same time, the limiting groove 6 applies a limit to the limiting slider 7. When the limiting slider 7 slides to a certain position, the limiting card 8 is inserted into the slot inside the limiting groove 6, fixing the positions of the limiting card 8 and the magnetic block 9, thus completing the installation of the magnetic block 9. The magnetic block 9 can be removed by sliding the limiting slider 7 in the opposite direction.
[0030] Second step: When the limiting block 8 is inserted into the limiting slot 10, the limiting block 8 applies a limit to the limiting slot 10, fixing the position of the limiting block 8, thereby fixing the position of the magnetic block 9. The magnetic block 9 can be removed, and the card body 5 can be pressed to make the suction cup 11 adhere to the surface to be adhered, thereby fixing the card body 5. When the card body 5 slides on the surface of the first limiting ring 1, the rectangular slot 12 limits the position of the card body 5, preventing the card body 5 from falling.
[0031] The third step: By setting rare earth permanent magnets, the overall performance of the magnetic attraction structure can be improved. The limiting block 3 is inserted into the circular slot 4, and at the same time, the circular slot 4 applies a limit to the limiting block 3, so that the first limiting ring 1 and the second limiting ring 2 are connected and fixed.
