Description

Technical Field

[0001] This utility model relates to the field of office supplies technology, and in particular to a magnetic plastic folder with quick-release layers. Background Technology

[0002] Plastic folders and document organizers are widely used in daily office work, study, and file management. Traditional plastic folders are mostly loose-leaf binders, clip-on folders, snap-lock pockets, or multi-layered accordion bags, using metal clips, plastic clamps, snaps, or buckles to hold and seal documents. However, these structural designs are usually quite fixed and lack flexibility, making it difficult to meet users' needs for classifying, organizing, and flexibly combining documents. For example, when users need to manage documents of different categories and frequencies of use in layers, traditional folders often do not provide convenient splitting and reorganization functions, resulting in low file organization efficiency. Furthermore, adjusting the order of documents or removing some documents is cumbersome and can easily lead to problems such as scattered or damaged documents, seriously affecting the user experience.

[0003] Furthermore, traditional folders are lacking in both tactile feedback and aesthetics. Internally, they typically only have a single shelf or fixed dividers, with each shelf connected as a single unit. Multi-layered folders or storage boxes use mechanical connectors such as screws, clips, and pins to hold the shelves together, making quick assembly and disassembly impossible. When needing to manage or group documents of different categories or usage frequencies, the entire folder must be moved or reorganized, lacking flexibility. Additionally, the protruding connectors can cause scratches and snags, negatively impacting the user experience. Existing technology urgently needs improvement to address these issues.

[0022] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application.

[0023] Traditional plastic folders typically use metal clips, plastic clamps, snaps, or buckles to hold and seal files. However, while these structures meet basic file storage needs, they also have limitations, particularly in terms of convenience and modular management. For example, when users frequently need to categorize, organize, or quickly access files within a folder, the traditional folder fixing method makes the process of disassembling and reassembling file layers cumbersome and time-consuming, hindering rapid layered management. This not only reduces work efficiency but may also lead to file damage or loosening of the folder structure due to frequent handling. If these problems are not addressed, users will continue to face inefficiency and inconvenience when dealing with large amounts of file categorization and management, severely impacting the user experience.

[0024] In response, this application proposes a magnetic plastic folder with quick-release layers. By introducing a magnetic connection structure and a mechanical locking structure, it enables quick separation and reassembly between the first placement layer 2 and the second placement layer 3, as well as reliable locking between the placement layers and the cover, thereby effectively solving the shortcomings of traditional folders in terms of layered management and convenience.

[0025] This embodiment discloses a magnetically attached plastic folder with a quick-release layer. See [link / reference] Figures 1 to 4 The folder mainly includes a cover 1, a first placement layer 2, a second placement layer 3, a magnetic connection structure, and a mechanical locking structure. The cover 1, serving as the folder's outer shell, is typically made of flexible plastic and provides protection for the internal documents. The first and second placement layers 2 and 3 are detachably located within the cover 1 and are used to store different types or purposes of documents. For example, the first placement layer 2 can be used to store frequently used documents, while the second placement layer 3 can be used to store less frequently accessed spare documents. The magnetic connection structure is located between the first and second placement layers 2 and 3 to achieve a detachable connection between them. The mechanical locking structure is located between the cover 1 and the overall structure formed by the first and second placement layers 2 and 3 to detachably lock the cover 1 to the overall structure.

[0026] Specifically, the cover 1 can adopt a one-piece structure, including an upper cover 11, a lower cover 12, and a sidewall 13 connecting the upper cover 11 and the lower cover 12. This one-piece design makes the cover 1 more integral and structurally stable. The first placement layer 2 and the second placement layer 3 can be made of transparent or semi-transparent plastic material to facilitate users' viewing of the internal documents. The magnetic connection structure can take various forms. For example, a groove 22 can be provided on the first placement layer 2, and a protrusion 31 can be provided on the second placement layer 3 adjacent to the first placement layer 2. The protrusion 31 and the groove 22 can be inserted and matched to achieve connection. To enhance the magnetic attraction effect, an iron piece can be provided in the protrusion 31 and a magnetic strip can be provided in the groove 22. The first placement layer 2 and the second placement layer 3 can be reliably positioned and quickly separated by magnetic attraction. The mechanical locking structure can include a card interface 51 provided at one end of the first placement layer 2 and the second placement layer 3, and a buckle 4 provided on the cover 1 and cooperating with the card interface 51. The latching member 4 may include a latching plate 41 that can extend into the card interface 51 for locking or releasing the first placement layer 2 and the second placement layer 3.

[0027] In a preferred embodiment, the upper cover 11 of the cover 1 may be provided with a pull tab 7 for easy opening and closing of the folder. Furthermore, to further enhance the connection stability between the cover 1 and the first placement layer 2 and the second placement layer 3, a positioning block 6 may be provided at one end of the first placement layer 2 and the second placement layer 3, and a positioning groove 132 that mates with the positioning block 6 may be provided on the side wall 13. After the positioning block 6 is inserted into the positioning groove 132, it can effectively prevent shaking between the cover 1 and the first placement layer 2 and the second placement layer 3, as well as between the first placement layer 2 and the second placement layer 3, in the connected state, thereby improving the overall connection stability and user experience.

[0028] When using the magnetic plastic folder with quick-release layers in this embodiment, users can quickly separate or combine the first placement layer 2 and the second placement layer 3 as needed. When it is necessary to classify or organize files, simply separate the first placement layer 2 and the second placement layer 3 using the magnetic connection structure to easily access or place files. For example, when a user needs to archive files in the folder, they can first unlock the cover 1 from the first placement layer 2 and the second placement layer 3 as a whole using the mechanical locking structure, and then remove the first placement layer 2 and the second placement layer 3 one by one using the magnetic connection structure to achieve quick classification and archiving of files. When it is necessary to recombine files, simply reconnect the first placement layer 2 and the second placement layer 3 using the magnetic connection structure and lock the whole thing inside the cover 1 using the mechanical locking structure. This design allows the internal structure of the folder to be flexibly adjusted according to actual needs, significantly improving the convenience and efficiency of file management. In addition, the mechanical locking structure between the cover 1 and the first placement layer 2 and the second placement layer 3, such as the cooperation between the buckle 4 and the card interface 51, ensures the stability of the folder during carrying and use, preventing files from accidentally falling out. Through the synergistic effect of the magnetic connection structure and the mechanical locking structure, the magnetically attached plastic folder of this application realizes modular, quick-release and quick-installation of file layer management.

[0029] In some of the embodiments described above, this application further proposes a specific implementation of the mechanical locking structure, aiming to provide a solution that is easy to operate and provides a stable locking mechanism. Specifically, the mechanical locking structure includes a card interface 51 disposed at one end of the first placement layer 2 and the second placement layer 3, and a latching member 4 disposed on the cover 1 and cooperating with the card interface 51. The latching member 4 includes a latching plate 41 that can be movably inserted into the card interface 51 for locking or releasing the first placement layer 2 and the second placement layer 3. The card interface 51 is disposed at the edge or side of the first placement layer 2 and the second placement layer 3, and engages with the latching plate 41 of the latching member 4 mounted on the cover 1, thereby locking or releasing the first placement layer 2 and the second placement layer 3 within the cover 1 as needed.

[0030] In some embodiments of this application, the mechanical locking structure is used to detachably lock the cover 1 to the first placement layer 2 and the second placement layer 3 as a whole. To improve ease of use, this application optimizes the latching member 4 so that the latching plate 41 can automatically reset after completing the locking or releasing operation, thereby improving the efficiency and reliability of the mechanical locking structure. Specifically, the latching member 4 also includes a housing 42 and a spring 45. The latching plate 41 is disposed inside the housing 42, and the spring 45 is disposed between the housing 42 and the latching plate 41 for driving the latching plate 41 to reset. The housing 42 is used to accommodate and protect the latching plate 41 and the spring 45, and is fixed to the cover 1; the spring 45 is compressed when the latching plate 41 is pressed, and provides a restoring force after the external force is removed, so that the latching plate 41 automatically returns to its initial position.

[0031] In some preferred embodiments, the housing 42 is securely fixed to the side wall 13 of the cover 1, and the snap-fit ​​plate 41 slides through the groove 421 inside the housing 42. When the user presses or pulls the snap-fit ​​plate 41 to unlock or lock the first placement layer 2 and the second placement layer 3, the spring 45 is compressed. After releasing the user, the snap-fit ​​plate 41 resets under the action of elasticity and re-inserts into the card interface 51, thereby completing the automatic locking.

[0032] In the above embodiments of this application, the latching member 4 extends into the card interface 51 via the latching plate 41 to lock and release the first placement layer 2 and the second placement layer 3. However, during frequent use, friction between the latching plate 41 and the housing 42 may cause wear, affecting the lifespan and reliability of the latching member 4. To address this, this application proposes an improvement: flanges 412 are provided on both sides of the latching plate 41, and a sliding groove 421 is provided on the housing 42 to slide and engage with the flanges 412. The engagement of the flanges 412 and the sliding groove 421 reduces direct friction between the latching plate 41 and the housing 42, improving the durability of the latching member 4. In one specific embodiment, a pressing groove 411 can be provided in the middle of the latching plate 41 along the width direction, facilitating the user to drive the latching plate 41 to reciprocate by pressing with their fingers. An extension post 43 is integrally formed on the inner side of the snap-fit ​​plate 41. The extension post 43 extends into the thickened side wall 13 of the cover 1, and a guide and limiting structure is formed on its inner side by a limiting post 44 and a spring 45. The spring 45 is sleeved on the outer periphery of the limiting post 44, with one end abutting the bottom of the inner groove and the other end abutting the end of the limiting post 44, thereby further ensuring the stability of the reset stroke of the snap-fit ​​plate 41. A mounting block 46 can be provided on the upper side of the snap-fit ​​member 4 for reliable connection with the mounting groove on the side wall 13. The lower side of the snap-fit ​​member 4 can cooperate with the slot 131 on the side wall 13 to prevent the snap-fit ​​member 4 from shaking during long-term use.

[0033] In some embodiments of this application, the first placement layer 2 and the second placement layer 3 are connected by a simple mechanical connection structure. Although interlayer connection can be achieved, the connection method is relatively simple. To address this, this application proposes a magnetic connection structure: a groove 22 is provided on the first placement layer 2, and a protrusion 31 is provided on the second placement layer 3 adjacent to the first placement layer 2. The protrusion 31 and the groove 22 are interlocked, thereby enabling quick disassembly and connection between the first placement layer 2 and the second placement layer 3. The groove 22 is used to accommodate the protrusion 31, and can specifically be a long strip or other recessed structure that matches the protrusion 31. The two can be designed as a tight fit or a slight gap as needed to facilitate disassembly.

[0034] In the above embodiments of this application, the protrusion 31 and the groove 22 are connected by an insertion joint. To improve the stability and reliability of the connection, this application optimizes the magnetic connection structure by placing an iron sheet inside the protrusion 31 and a magnetic strip inside the groove 22. The magnetic attraction enhances the connection strength between the first placement layer 2 and the second placement layer 3, improving the overall stability of the folder. As a specific embodiment, the protrusion 31 can be integrally formed with the second placement layer 3 using injection molding, and the iron sheet can be fixed inside the protrusion 31 by embedded injection molding or other methods. The groove 22 can be integrally formed with the first placement layer 2, and the magnetic strip can be fixed inside the groove 22 by bonding or covering. During assembly, simply align the protrusion 31 of the second placement layer 3 with the groove 22 of the first placement layer 2 and insert it. Under the action of magnetic force, the two placement layers automatically attract together, achieving a quick and stable connection.

[0035] In another specific embodiment of this application, to enable the cover 1 to also have a quick-release magnetic connection structure with the first placement layer 2 and the second placement layer 3, a first magnetic connection structure and a third magnetic connection structure can be provided. The first magnetic connection structure may include a first protrusion 111 provided on the inner folded edge of the upper cover 11 and a first groove 21 provided on the first placement layer 2. Iron sheets and magnetic strips are respectively provided between the first protrusion 111 and the first groove 21 and are fixed by adhesive or wrapping, so as to realize automatic attraction and separation between the upper cover 11 and the first placement layer 2. The third magnetic connection structure may include a third protrusion 121 provided on the inner side of the lower cover 12 and a third groove 32 provided at the bottom of the second placement layer 3. Iron sheets and magnetic strips are also provided in the third protrusion 121 and the third groove 32, so as to reliably attract the second placement layer 3 to the lower cover 12 and facilitate overall assembly and disassembly, thereby forming three sets of modular magnetic connections in conjunction with the magnetic structure between the layers.

[0036] In the above embodiment, the upper cover 11 and the lower cover 12 constitute the front and back panels of the folder, respectively, for protecting the internal documents. The side wall 13 connects the upper cover 11 and the lower cover 12, forming a space to accommodate the first placement layer 2 and the second placement layer 3. A mechanical locking structure is provided on the side wall 13, which can more effectively fix the first placement layer 2 and the second placement layer 3 within the cover 1, preventing them from accidentally falling off during use. The side wall 13 can be made of a material with a certain degree of elasticity to facilitate the installation and operation of the mechanical locking structure. By placing the mechanical locking structure on the side wall 13, the structural strength of the side wall 13 can be used to enhance the locking effect. Compared to directly placing the mechanical locking structure on the upper cover 11 or the lower cover 12, it can avoid locking failure caused by panel deformation.

[0037] In this application, the cover 1 is typically a planar structure, and the first placement layer 2 and the second placement layer 3 are prone to displacement when placed inside the cover 1. This application addresses this by providing positioning blocks 6 at one end of the first placement layer 2 and the second placement layer 3, and by providing positioning grooves 132 on the side wall 13 that mate with the positioning blocks 6, thereby achieving proper positioning of the first placement layer 2 and the second placement layer 3. Multiple positioning blocks 6 can be provided and arranged at intervals along the length of the placement layers, and multiple positioning grooves 132 can be provided accordingly to improve the reliability of positioning.

[0038] As another implementation, magnets can be embedded in the inner sides of the upper cover 11 and the lower cover 12 respectively, and metal sheets can be provided on the surfaces of the corresponding first placement layer 2 and second placement layer 3. When the first placement layer 2 and the second placement layer 3 are placed inside the cover 1, the magnets and the metal sheets attract each other, thereby firmly fixing the first placement layer 2 and the second placement layer 3 inside the cover 1. The size and number of magnets can be adjusted as needed to obtain a suitable adsorption effect.

[0039] In the quick-release magnetic plastic folder of this application, a pull tab 7 is provided on the upper cover 11 of the cover 1 to facilitate users in opening and closing the folder more conveniently. The pull tab 7 can be made of materials such as plastic, metal or leather, and its shape and size can be adjusted according to actual needs. It is fixed to the upper cover 11 by riveting, gluing or sewing to ensure the connection is firm.

[0040] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
