Description
Technical Field
[0001] This utility model relates to the field of learning cards, and in particular to a retractable Chinese language learning card. Background Technology
[0002] Currently, traditional Chinese language learning flashcards are mostly single-page, independent designs, which are easily scattered and lost during use and cannot be stored in an orderly manner. Learners need to frequently tidy them up when looking up information, resulting in low efficiency.
[0003] While existing bound card holders solve the storage problem, the fixed binding method makes it difficult to flexibly change or rearrange the content, making it hard to adapt to personalized learning needs. At the same time, traditional cards can only display text or pictures on one side, lacking the intuitiveness of text and picture comparison, which affects the learning effect.
[0004] To address the aforementioned issues, this patent proposes a Chinese language learning flashcard that integrates storage, page turning, quick sorting, and modular replacement, thereby meeting the comprehensive needs for intuitive content, flexibility, and portability in the language learning process. Utility Model Content
[0005] The main purpose of this invention is to propose a retractable Chinese language learning card, which aims to solve the problem that traditional Chinese language learning cards cannot be flexibly changed or rearranged.
[0006] To address the aforementioned problems, this utility model proposes a retractable Chinese language learning card, comprising a fixed pressure plate, with multiple arc-shaped fixed limiting rings connected to the lower end of the fixed pressure plate, a movable pressure plate disposed on the front side of the fixed pressure plate, with multiple arc-shaped movable limiting rings connected to the lower end of the movable pressure plate and attached to the upper front side of the multiple movable limiting rings, and the multiple fixed limiting rings respectively inserted into the upper end of the multiple movable limiting rings, with multiple connecting card seats disposed at the lower end of the multiple movable limiting rings, and the multiple movable limiting rings all passing through the upper side of the multiple connecting card seats and slidably connected to the multiple connecting card seats, and graphic cards disposed at the lower end of the multiple connecting card seats.
[0007] Preferably, the upper end of the graphic card has a connecting card slot, and the connecting card holder is inserted into the connecting card slot. Multiple limiting card heads are provided on the inside of both the front and rear ends of the connecting card slot.
[0008] Preferably, the connecting card holder has multiple limiting holes running through its lower side, and multiple limiting heads are respectively engaged with the front and rear ends of the multiple limiting holes.
[0009] Preferably, an arc-shaped limiting sliding hole is provided on the front side of the upper end of the moving limiting ring, and the fixed limiting ring is inserted into the interior of the front side of the upper end of the moving limiting ring through the limiting sliding hole.
[0010] Preferably, an arc-shaped limiting slip ring is connected to the front side of the lower end of the limiting ring, and the limiting slip ring is slidably connected inside the limiting sliding hole.
[0011] Preferably, an arc-shaped guide ring is connected to the center of the inner wall of the upper end of the limiting slip ring, and a sealing spring is sleeved on the outside of the guide ring, with the sealing spring located inside the limiting slip ring.
[0012] Preferably, the limiting slip ring is elastically connected to the inside of the limiting slip hole by a sealed spring, and the lower center of the limiting slip hole is connected to an arc-shaped guide ring slip hole, and the lower end of the guide ring is inserted into the inside of the guide ring slip hole and slidably connected with the guide ring slip hole.
[0013] Beneficial effects:
[0014] 1. This utility model achieves the overall storage and page-turning functions of learning cards through the nested insertion and connection of an arc-shaped fixed limiting ring and a movable limiting ring. The movable limiting ring can slide on the fixed limiting ring, and in conjunction with the limiting function of the connecting card holder, multiple picture cards can be folded and stored, and can also be flipped continuously like a book, improving the portability and interactivity of learning cards, while avoiding the easy loss of traditional loose cards.
[0015] 2. The graphic card and connecting card holder of this utility model adopts an elastic snap-fit design of limiting card head and limiting card hole. It can be disassembled by simply pulling down and installed by pushing up. Card replacement can be completed without auxiliary tools. Furthermore, the cards can be separated and reordered by separating the back of the fixed limiting ring and the moving limiting ring. This allows for flexible adjustment of content according to the learning progress, while ensuring a stable connection during use and preventing accidental detachment.
[0016] 3. When the moving pressure plate is pressed, the moving limit ring and the fixed limit ring are guided to separate by the guide ring to form an opening gap, which makes it easy to quickly remove the entire set of graphic cards along with the connecting card holder and adjust the order; after being released, it automatically resets and closes to form a closed ring to fix the card, avoiding the drawbacks of the traditional ring-type card disassembly and improving the card sorting efficiency.
[0017] 4. This utility model utilizes the cooperation of a sealed spring and an arc-shaped guide ring to maintain elastic tension in the moving limit ring during sliding, ensuring smooth opening and closing while tightly locking the fixed limit ring when closed. It balances ease of operation with structural durability, preventing loosening and deformation after prolonged use.
[0018] 5. Each card of this utility model has text and corresponding pictures printed on the front and back respectively. By flipping or taking out the cards individually, intuitive picture and text comparison learning can be achieved. Combined with the spatial arrangement of the storage structure, it ensures that the content on both sides can be clearly displayed, enhancing the visual memory effect. Attached Figure Description

[0027] 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.
[0028] To achieve the above-mentioned utility model objectives, such as Figures 1-5As shown, this utility model provides a retractable Chinese language learning card, including a fixed pressure plate 1, with multiple arc-shaped fixed limiting rings 2 connected to the lower end of the fixed pressure plate 1, a movable pressure plate 3 provided on the front side of the fixed pressure plate 1, with multiple arc-shaped movable limiting rings 4 connected to the lower end of the movable pressure plate 3 and connected to the upper front side of the multiple movable limiting rings 4, and the multiple fixed limiting rings 2 are respectively inserted into the upper end of the multiple movable limiting rings 4, and multiple connecting card seats 5 are provided at the lower end of the multiple movable limiting rings 4, and the multiple movable limiting rings 4 all pass through the upper side of the multiple connecting card seats 5 and are slidably connected to the multiple connecting card seats 5, and each of the multiple connecting card seats 5 is provided with a picture card 6. During the Chinese language learning process, the outer walls of the front and rear ends of the picture card 6 are respectively provided with text and pictures, which can enhance the intuitiveness through the comparison of text and pictures on the outer walls of the picture card 6, and help learners remember the learning content. The multiple picture cards 6 can all be connected to the multiple movable limiting rings 4 through the connecting card seats 5 and stored together through the multiple movable limiting rings 4.
[0029] Multiple graphic cards 6 can be detached from the connecting card holder 5 by pulling them down for individual use. Multiple graphic cards 6 can be stored in the lower end of multiple moving limit rings 4 through the connecting card holder 5, and can be flipped through the sliding connection between the moving limit rings 4 and the connecting card holder 5, so that multiple graphic cards 6 can be used as a whole after storage. In addition, graphic cards 6 can be removed from the lower end of the connecting card holder 5 for replacement according to the learning progress, and can be removed together with the connecting card holder 5 from the lower end of the multiple moving limit rings 4 for reordering.
[0030] Preferably, the graphic card 6 has a connecting slot 7 at its upper end, and the connecting card holder 5 is inserted into the connecting slot 7. Multiple limiting heads 8 are provided inside both the front and rear ends of the connecting slot 7. Multiple limiting holes 9 extend through the lower side of the connecting card holder 5, and the multiple limiting heads 8 respectively engage with the front and rear ends of the multiple limiting holes 9. During the removal and replacement of the graphic card 6, the graphic card 6 can connect to the connecting card holder 5 through the connecting slot 7 and can be limited by the multiple limiting heads 8 and the multiple limiting holes 9. When the graphic card 6 is removed from the lower end of the connecting card holder 5, pull the graphic card 6 downwards, causing multiple limiting heads 8 to move downwards together, allowing the multiple limiting heads 8 to be disengaged from the multiple limiting holes 9, so that the graphic card 6 can be smoothly removed from the lower end of the connecting card holder 5. Conversely, push the graphic card 6 upwards, causing the multiple limiting heads 8 to slide upwards together, allowing the connecting card holder 5 to be inserted into the connecting card slot 7, and causing the multiple limiting heads 8 to be disengaged into the front and rear ends of the multiple limiting holes 9, so that the graphic card 6 can be firmly connected to the lower end of the connecting card holder 5.
[0031] Preferably, the upper front side of the movable limiting ring 4 has an arc-shaped limiting sliding hole 10, and the fixed limiting ring 2 is inserted into the upper front side of the movable limiting ring 4 through the limiting sliding hole 10. The lower front side of the fixed limiting ring 2 is connected to an arc-shaped limiting sliding ring 11, and the limiting sliding ring 11 is slidably connected inside the limiting sliding hole 10. An arc-shaped guide ring 12 is connected to the center of the upper inner wall of the limiting sliding ring 11. A sealing spring 13 is sleeved on the outside of the guide ring 12, and the sealing spring 13 is located inside the limiting sliding ring 11. The limiting sliding ring 11 is elastically connected to the inside of the limiting sliding hole 10 through the sealing spring 13. An arc-shaped guide ring sliding hole 14 is connected to the center of the lower end of the limiting sliding hole 10, and the lower end of the guide ring 12 is inserted into... Inside the guide ring sliding hole 14 and slidably connected to the guide ring sliding hole 14, during the sorting of multiple graphic cards 6, the moving pressure plate 3 is pressed backward. The moving pressure plate 3 drives the front side of multiple moving limit rings 4 to slide upward in an arc along the front side of the fixed limit ring 2. At the same time, the fixed limit ring 2 and the limit sliding ring 11 slide downward inside the limit sliding hole 10. The guide ring 12 slides into the guide ring sliding hole 14 and compresses the sealing spring 13, causing the upper rear side of the moving limit ring 4 to separate from the lower rear side of the fixed limit ring 2 and open a notch. At this time, the connecting card seat 5 can be taken out from the notch, allowing multiple graphic cards 6 to be taken out from the lower end of multiple moving limit rings 4 together with the connecting card seat 5 for sorting.
[0032] Conversely, after the sorting is completed, the moving pressure plate 3 is released. Under the action of the sealing spring 13, the moving pressure plate 3 and the moving limit ring 4 slide downward in an arc along the front side of the fixed limit ring 2. At the same time, the fixed limit ring 2 and the limit sliding ring 11 slide upward inside the limit sliding hole 10. The guide ring 12 slides out of the guide ring sliding hole 14, allowing the rear side of the fixed limit ring 2 to fit against the rear side of the moving limit ring 4 again. It is then inserted into the upper rear side of the moving limit ring 4 through the locking hole, which is located on the upper rear side of the moving limit ring 4. This allows the fixed limit ring 2 and the moving limit ring 4 to form a complete sealed ring, thereby limiting the multiple connecting card seats 5 inside the sealed ring and limiting the sorted multiple connecting card seats 5 and multiple graphic cards 6 to prevent them from falling off.
[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
