Technical Field
[0001] This utility model relates to the field of book storage technology, and in particular to a book storage box structure. Background Technology
[0002] In daily study, work, and life, the storage and organization of books is a common problem. Currently, the most common book storage tools on the market include bookshelves, storage boxes, and storage bags. Among them, book storage boxes are widely used in homes, schools, offices, and other settings because they take up little space, are flexible and movable, and provide good protection for books.
[0003] Existing book organizers are typically boxes with a cavity, into which books are neatly stacked or arranged. However, these traditional organizers have some shortcomings in practical use: when storing a small number of books, they are prone to tipping over or tilting within the cavity, leading to broken corners. Furthermore, re-aligning the books is inconvenient when retrieving or rearranging them. Some organizers incorporate fixed baffles to address these issues, but these baffles are mostly fixed in position and cannot be flexibly adjusted according to the number of books, resulting in poor applicability and failing to meet user needs.

[0042] Please refer to the following: Figures 1 to 6 This embodiment provides a book storage box structure, including a box body 100, a sliding plate 200, a tension spring 300, and a frame 400. The box body 100 has a receiving cavity for accommodating books, and an installation space is provided in the box body 100. A spring groove 112 is provided in the installation space, and a first mounting post 113 is provided at one end of the spring groove 112. The sliding plate 200 is slidably installed in the installation space, and the sliding plate 200 can slide along the extending direction of the spring groove 112. A second mounting post 210 is provided on the sliding plate 200. The second mounting post 210 is inserted into the spring groove 112. The tension spring 300 is installed in the spring groove 112. One end of the tension spring 300 is connected to the first mounting post 113, and the other end of the tension spring 300 is connected to the second mounting post 210. The frame 400 is detachably installed on the sliding plate 200 so that the elastic force of the tension spring 300 can press the book in the accommodating cavity between the inner wall of the box 100 and the frame 400.
[0043] As can be seen, the book storage box structure of this embodiment, by setting a structure with a spring groove 112 and a first mounting post 113 in the installation space of the box body 100, cooperates with a sliding plate 200 that can slide along the spring groove 112 and is provided with a second mounting post 210, and a tension spring 300 connecting the first mounting post 113 and the second mounting post 210, and the frame 400 is detachably installed on the sliding plate 200, can use the elastic force of the tension spring 300 to press the books in the accommodating cavity between the inner wall of the box body 100 and the frame 400, to achieve adaptive and stable clamping for different numbers of books and prevent the books from shaking and scattering; at the same time, the detachable design of the frame 400 makes it easy to replace or maintain according to the book specifications, and the partitioning of the installation space and the accommodating cavity avoids the drive components occupying the storage space, thus improving the overall stability of storage, ease of operation, structural flexibility and space utilization.
[0044] In this embodiment, the housing 100 includes an outer shell 110 and an inner shell 120. The inner shell 120 is detachably mounted on the outer shell 110 to form an installation space between the inner shell 120 and the outer shell 110.
[0045] By setting the box 100 to be detachably connected to the outer shell 110 and the inner shell 120, and forming an installation space between them, the assembly and subsequent maintenance and replacement of components such as the sliding plate 200 and the tension spring 300 inside the installation space are facilitated, thereby improving the assembly flexibility and practicality of the overall structure.
[0046] Preferably, the outer shell 110 has a second elastic fastening protrusion 121, and the inner shell 120 is provided with a second fastening groove 111 corresponding to the second elastic fastening protrusion 121, so that the outer shell 110 and the inner shell 120 can be detachably connected by fastening the second elastic fastening protrusion 121 into the second fastening groove 111.
[0047] The outer shell 110 is provided with a second elastic fastening protrusion 121 and the inner shell 120 is provided with a corresponding second fastening groove 111. The elastic fastening structure enables the detachable connection between the outer shell 110 and the inner shell 120. This not only ensures the stability of the connection between the two, but also simplifies the assembly and disassembly operation. The assembly or disassembly of the outer shell 110 and the inner shell 120 can be easily completed without additional tools, which facilitates the inspection and replacement of internal components in the installation space. At the same time, the elastic fastening method has a simple structure and low cost, which can improve the assembly efficiency and ease of use of the overall structure while ensuring the reliability of the connection.
[0048] In this embodiment, the housing 100 is provided with a guide groove 122, the extension direction of the guide groove 122 is parallel to the extension direction of the spring groove 112, and the sliding plate 200 is provided with a guide protrusion 220, which at least partially penetrates the guide groove 122 so that the sliding plate 200 can slide along the extension direction of the spring groove 112.
[0049] Specifically, by setting a guide groove 122 on the box body 100 parallel to the extension direction of the spring groove 112, and setting a guide protrusion 220 on the sliding plate 200 that passes through the guide groove 122, a precise limit is formed on the sliding direction of the sliding plate 200, ensuring that the sliding plate 200 always slides stably along the extension direction of the spring groove 112, avoiding deviation, jamming or tilting during movement, thereby ensuring that the elastic force of the tension spring 300 can stably act on the frame 400 to press the books; at the same time, the guide structure enhances the smoothness of the sliding plate 200, improves the stability and service life of the overall structure, and ensures that the storage box can maintain a good adjustment and pressing effect during long-term use.
[0050] Preferably, the guide groove 122 is configured to connect the installation space with the external environment, so that the frame 400 can be detachably connected to the sliding plate 200 through the guide groove 122.
[0051] By setting the guide groove 122 to connect the installation space with the external environment, the frame 400 can pass through the guide groove 122 and be detachably connected to the sliding plate 200. This not only ensures the stable sliding function of the sliding plate 200 along the guide groove 122, but also provides a convenient channel for the assembly and disassembly of the frame 400 and the sliding plate 200. The frame 400 can be installed, replaced, or maintained without disassembling the box 100. At the same time, this design allows the frame 400 to directly act on the books in the accommodating cavity, ensuring that the elastic force of the tension spring 300 is effectively transmitted to the frame 400 through the sliding plate 200 to achieve a clamping effect. This simplifies the structural connection relationship and improves the ease of use and the overall structural synergy.
[0052] Preferably, the bottom of the frame 400 is provided with a first elastic fastening protrusion 411, and the sliding plate 200 is provided with a first fastening groove 230 corresponding to the first elastic fastening protrusion 411, so that the frame 400 and the sliding plate 200 can be detachably connected by passing the first elastic fastening protrusion 411 through the guide groove 122 and fastening it into the first fastening groove 230.
[0053] Specifically, by setting a first elastic fastening protrusion 411 at the bottom of the frame 400 and a corresponding first fastening groove 230 on the sliding plate 200, the frame 400 can pass through the guide groove 122 to achieve a detachable connection with the sliding plate 200 through elastic fastening. This structure not only ensures the stability of the connection between the frame 400 and the sliding plate 200, but also allows for quick assembly and disassembly of the frame 400 without tools, facilitating the replacement of different frames 400 according to book specifications or the individual maintenance of the frame 400. At the same time, the elastic fastening method can adapt to the sliding movement of the sliding plate 200, ensuring that the elastic force of the tension spring 300 is stably transmitted to the frame 400, improving the convenience of assembly and disassembly without affecting the reliability of the overall clamping function.
[0054] In this embodiment, the top of the spring groove 112 is provided with an opening 114 so that the tension spring 300 can be installed into the spring groove 112 through the opening 114.
[0055] By setting the top of the spring groove 112 as an opening 114, the tension spring 300 can be easily installed into the spring groove 112 through the opening 114, simplifying the assembly process of the tension spring 300 and allowing the installation of the tension spring 300 to be completed without complicated operations. At the same time, this design also facilitates the later inspection, maintenance or replacement of the tension spring 300, reducing the difficulty of assembly and maintenance. While ensuring the installation stability of the tension spring 300, it improves the production efficiency and maintenance convenience of the overall structure.
[0056] In this embodiment, the frame 400 includes a sliding member 410 and a rotating member 420. The sliding member 410 is detachably connected to the sliding plate 200, and the rotating member 420 is rotatably mounted on the sliding member 410. The rotating member 420 can rotate relative to the sliding member 410 to a first position and a second position. In the first position, the plane of the rotating member 420 is approximately perpendicular to the bottom of the box 100, and in the second position, the plane of the rotating member 420 is approximately parallel to the bottom of the box 100.
[0057] The design features a shelf 400 divided into a sliding member 410 detachably connected to the sliding plate 200, and a rotating member 420 rotatably mounted on the sliding member 410. The rotating member 420 can rotate relative to the sliding member 410 to a first position approximately perpendicular to the bottom of the box 100 and a second position approximately parallel to the bottom, greatly enhancing storage flexibility. In the first position, the rotating member 420 effectively blocks and presses, firmly holding the books in the accommodating cavity and preventing them from shaking and scattering. In the second position, the rotating member 420 fits against the bottom of the box 100, reducing the space occupied in the accommodating cavity and facilitating the insertion or removal of thicker books. It also allows for flexible adjustment of the shelf 400 when books do not need to be pressed, thus balancing the need for stable storage and flexible access to books and enhancing the adaptability of the storage box to different usage scenarios.
[0058] Preferably, the sliding member 410 is provided with a limiting protrusion 412, so that when the rotating member 420 rotates to the first position, the limiting protrusion 412 abuts against the rotating member 420 to restrict the rotating member 420 from continuing to rotate towards the bottom of the box 100.
[0059] By setting a limiting protrusion 412 on the slider 410, when the rotating member 420 rotates to the first position for pressing the book, the limiting protrusion 412 can abut against the rotating member 420 to limit its continued rotation towards the bottom of the box 100. This design ensures that the rotating member 420 is stably maintained in a working posture that is approximately perpendicular to the bottom of the box 100, avoiding excessive rotation of the rotating member 420 due to book compression or external force contact, thus ensuring that the elastic force of the tension spring 300 can be effectively transmitted to the book through the rotating member 420, continuously and firmly clamping the book. At the same time, there is no need to set up an additional complex locking structure. The precise positioning of the rotating member 420 can be achieved solely through the limiting protrusion 412, which simplifies the structure and improves the reliability of the overall storage function.
[0060] In this embodiment, the first mounting post 113 and the second mounting post 210 are respectively arranged vertically. One end of the tension spring 300 is provided with a first collar 320 and the other end of the tension spring 300 is provided with a second collar 330. The first collar 320 is sleeved on the first mounting post 113 and the second collar 330 is sleeved on the second mounting post 210.
[0061] In this design, by vertically arranging the first mounting post 113 and the second mounting post 210, and correspondingly setting the first collar 320 and the second collar 330 at both ends of the tension spring 300, the tension spring 300 can be directly fitted onto the mounting post through the collars to achieve connection. This connection method simplifies the assembly process of the tension spring 300, avoids the tension spring 300 from shifting, falling off, or experiencing uneven force during the sliding of the sliding plate 200, and ensures stable transmission of elastic force to achieve the book-pressing effect. At the same time, the cooperation between the collar and the mounting post also facilitates the disassembly, maintenance, or replacement of the tension spring 300 in the later stages, improving the assembly efficiency of the structure while enhancing the overall reliability and service life.
[0062] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0063] The book storage box structure of this utility model, by setting a structure with a spring groove 112 and a first mounting post 113 in the installation space of the box body 100, cooperates with a sliding plate 200 that can slide along the spring groove 112 and is provided with a second mounting post 210, and a tension spring 300 connecting the first mounting post 113 and the second mounting post 210, and the frame 400 is detachably installed on the sliding plate 200. With the elastic force of the tension spring 300, the frame 400 can press the books in the accommodating cavity between the inner wall of the box body 100 and the frame 400, realizing adaptive and stable clamping for different numbers of books and preventing the books from shaking and scattering. At the same time, the detachable design of the frame 400 makes it easy to replace or maintain according to the size of the books, and the partitioning of the installation space and the accommodating cavity avoids the drive components occupying the storage space. Overall, it improves the stability of storage, the convenience of operation, the structural flexibility and the space utilization rate.
