Description

Technical Field

[0001] This utility model relates to the field of learning aids, and in particular to an English vocabulary memory card box. Background Technology

[0002] Flashcards are a widely used tool for learning English vocabulary, and the ease of their storage and management directly affects the user experience. However, existing products have significant shortcomings in terms of high adaptability and stackable storage, making it difficult to meet learning needs.

[0003] Firstly, the height adjustment capability is lacking, resulting in poor adaptability. Flashcards used in English learning come in various sizes, but most existing card holders have a fixed height. Large cards are easily squeezed and deformed, while small cards wobble and wear inside the holder, and are prone to tipping over and becoming disordered when being taken out or put in. Even the few adjustable card holders available have complex adjustment mechanisms and cumbersome operations, making it impossible to quickly match card sizes.

[0004] Secondly, the stacking stability is insufficient and the storage efficiency is low. Learners often need to store vocabulary in multiple sets of card boxes, but the existing card boxes do not have a dedicated stacking positioning structure and rely solely on gravity to stack. They are easily tipped over by external force, causing the cards to scatter. At the same time, the stacking is prone to misalignment, takes up a lot of space, and is inconvenient for centralized management and quick retrieval.

[0005] These problems reduce the preservation quality and ease of learning of flashcards, thus necessitating a highly adjustable and stackable English vocabulary flashcard box to compensate for the shortcomings of existing technology. Utility Model Content

[0006] In order to overcome the shortcomings of existing English vocabulary memory card boxes, such as inconvenient height adjustment and poor stacking stability, this utility model provides an English vocabulary memory card box.

[0007] An English vocabulary memory card box includes a base frame, a lifting frame, elastic card posts, elastic card blocks, and wedge-shaped card teeth. The base frame is a split structure, with at least two units. Each base frame is slidably connected to a lifting frame, and the base frames are stacked. Positioning holes are provided at the two front corners of the top of the lifting frame. Elastic card posts are fixed to the bottom of the base frame at positions corresponding to the positioning holes, and the elastic card posts and positioning holes form a snap-fit ​​relationship. The base frame is divided into two storage positions. Elastic card blocks are fixed to the outer walls of both sides of the lifting frame. Wedge-shaped card teeth are continuously distributed on the outer walls of both sides of the base frame at positions corresponding to the elastic card blocks, and the elastic card blocks and wedge-shaped card teeth form a snap-fit ​​relationship.

[0008] To further explain, it also includes guide rods, compression springs, and pressure plates. Guide rods are symmetrically fixed to the inner side wall of the lifting frame corresponding to the two storage positions. A pressure plate is slidably connected between the two guide rods in the same storage position. Compression springs are sleeved on the outer side of the guide rods. One end of the compression spring abuts against the wall surface of the pressure plate, and the other end abuts against the inner wall of the lifting frame.

[0009] To further explain, the compression spring still maintains a pre-compression amount when the pressure plate is in the final position.

[0010] To further explain, each pressure plate has two finger grooves, which are in the form of a ring.

[0011] To further explain, it also includes baffles, and multiple mounting slots are spaced apart on the front and rear side walls of the two corresponding storage positions inside the bottom frame. The thickness of the baffles is adapted to the width of the mounting slots, and they are snap-fitted between the two opposite mounting slots.

[0012] To further explain, it also includes a cover plate, and a placement groove is provided on the top inner wall of the lifting frame. The shape of the cover plate is adapted to the placement groove and is engaged in the placement groove.

[0013] The beneficial effects of this utility model are as follows: 1. By engaging the elastic card block with the wedge-shaped card tooth, the height of the lifting frame can be adjusted in a step-like manner to meet the storage needs of memory cards of different heights and solve the problem of poor adaptability of traditional card boxes.

[0014] 2. Through the locking action of the elastic locking posts and positioning holes, multiple card boxes can be stably stacked, reducing storage space. The stacking structure is also easy to disassemble, making it convenient to classify and manage memory cards of different vocabulary categories.

[0015] 3. The elastic force of the compression spring drives the pressure plate to press the memory card, and the adjustable baffle restricts lateral displacement, effectively preventing the card from shaking and tipping over; at the same time, the naturally tilted structure of the bottom frame further improves the stability of card storage.

Detailed Implementation

[0022] Example: An English vocabulary memory card box, such as Figures 1-4 As shown, the device includes a base frame 1, a lifting frame 2, elastic locking posts 9, elastic locking blocks 10, and wedge-shaped locking teeth 11. There are at least two base frames 1, each with a lifting frame 2 slidably connected vertically. When two or more base frames 1 are stacked, the bottom of the upper base frame 1 is aligned with the top surface of the lifting frame 2 on the lower base frame 1. Positioning holes 8 are provided at the left and right corners of the top front side of the lifting frame 2. Elastic locking posts 9 are fixedly connected to the bottom of the base frame 1 at positions corresponding to the positioning holes 8. The elastic locking posts 9 have a conical structure, with their smaller diameter end facing downwards. When the base frames 1 are stacked... In the storage state, the elastic locking post 9 at the bottom of the upper bottom frame 1 can form an interference fit with the positioning hole 8 of the lifting frame 2 on the lower bottom frame 1 to achieve axial positioning of multiple bottom frames 1 stacked together. The bottom frame 1 is divided into two storage positions, left and right, for classifying and storing memory cards. Elastic locking blocks 10 are fixed to the outer walls of the left and right side walls of the lifting frame 2. The outer walls of the left and right side walls of the bottom frame 1 are provided with continuously distributed wedge-shaped locking teeth 11 in the vertical direction corresponding to the position of the elastic locking blocks 10. The elastic locking blocks 10 and the wedge-shaped locking teeth 11 form a locking fit to achieve the step-like adjustment and positioning of the height of the lifting frame 2.

[0023] like Figures 2-5 As shown, it also includes guide rods 5, compression springs 6, and pressure plates 7. Guide rods 5 are symmetrically welded to the inner sidewalls of the lifting frame 2 corresponding to the two storage positions. Pressure plates 7 are slidably connected between the two guide rods 5 in the same storage position. The edge of the pressure plate 7 slides against the inner sidewall of the lifting frame 2. Compression springs 6 are sleeved on the outer side of the guide rods 5. One end of the compression spring 6 abuts against the wall of the pressure plate 7, and the other end abuts against the inner wall of the lifting frame 2, forming an elastic pre-tightening force on the pressure plate 7. Two symmetrically distributed finger grooves are opened on the pressure plate 7. The finger grooves are in a ring structure to accommodate the force applied by the fingers, making it easy for users to push and pull the pressure plate 7 through the finger grooves. When the pressure plate 7 is in the last position, the compression spring 6 still maintains a pre-compression amount, ensuring that when the number of memory cards is small, the pressure plate 7 can still provide sufficient clamping force under the action of the compression spring 6, preventing a small number of cards from shaking or tipping over in the card box, thus expanding the applicability of the device.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes a baffle 4 and a cover plate 13. Multiple mounting slots 3 are spaced apart on the front and rear side walls corresponding to the two storage positions inside the bottom frame 1. The thickness of the baffle 4 is adapted to the width of the mounting slot 3 and can be snapped into the two opposite mounting slots 3. In the initial state, a baffle 4 is installed in the right storage position. The mounting slot 3 corresponding to the width of the memory card can be selected to install the baffle 4 to reduce the lateral space of the storage position. A placement groove 12 flush with its own top surface is opened on the top inner wall of the lifting frame 2. The shape of the cover plate 13 is adapted to the placement groove 12 and can be snapped into the placement groove 12 to achieve the sealing of the internal space of the bottom frame 1.

[0025] When it is necessary to store memory cards, the height of the lifting frame 2 can be adjusted. Depending on the height of the memory card to be stored, the elastic block 10 is moved away from the wedge-shaped teeth 11 to disengage it. Then, the lifting frame 2 is pulled up or down to the appropriate height. The lifting frame 2 causes the guide rod 5 and pressure plate 7 to move synchronously. After the height adjustment is complete, the elastic block 10 is released. Under its own elastic restoring force, the elastic block 10 resets and re-engages with the corresponding wedge-shaped teeth 11, thus realizing the lifting frame 2... After the height is fixed, the user inserts their finger into the finger groove of the pressure plate 7 and pulls the pressure plate 7 forward along the guide rod 5. The pressure plate 7 compresses the clamping spring 6 and moves forward, so that the storage position forms a space for the memory card to be placed. The memory cards are stacked and neatly placed in the left and right storage positions from back to front. After placement, the pressure plate 7 is released, the clamping spring 6 rebounds and resets, driving the pressure plate 7 to move along the guide rod 5 towards the memory card until the pressure plate 7 is tightly attached to the end face of the card, thus achieving axial clamping and fixing of the stacked cards.

[0026] When storing small-width memory cards, select the mounting slot 3 position that matches the card width, and insert both ends of the baffle 4 into the front and rear opposite mounting slots 3 respectively, so that the baffle 4 and the inner side wall of the lifting frame 2 form a limiting space adapted to the card width. One side of the memory card is attached to the baffle 4, and the other side is attached to the inner wall of the lifting frame 2. The bidirectional limiting prevents the card from shifting laterally, ensuring that the small-sized card is stored stably. After the memory card is placed, align the cover plate 13 with the placement groove 12 at the top of the lifting frame 2, and press the cover plate 13 down to lock it in place. The cover plate 13 seals the internal space of the bottom frame 1, preventing external dust from entering and completing the dust protection of the card.

[0027] When multiple card boxes need to be stacked for storage, first remove the cover plate 13 on the lower card box, place the upper card box horizontally on the top surface of the lifting frame 2 of the lower card box, align the elastic locking post 9 at the bottom of the upper card box with the positioning hole 8 of the lifting frame 2 of the lower card box, and gently press the upper card box down. The conical elastic locking post 9 will penetrate into the positioning hole 8 through its own deformation, forming an interference fit to achieve axial positioning. Stack multiple card boxes in this way, and finally install the cover plate 13 on the top card box to complete the overall sealing.

[0028] Furthermore, when the card holder is placed on the table, since the bottom frame 1 only abuts against the table through two elastic latches 9 on the front side of the bottom, and there is no support structure on the rear side, the bottom frame 1 naturally forms a slight tilt state with the front higher than the back. This tilt structure makes the memory cards in the storage compartment always tilted backward. Even when taking out a single card causes a change in local pressure, it can prevent the card from tilting forward due to the loss of local clamping force, thus improving the stability of the card taking process.
