Description

Technical Field

[0001] This application relates to the field of storage tools technology, and more specifically to a file box. Background Technology

[0002] File boxes are efficient and flexible file organization tools widely used in office, study, and home environments. Traditional file organization tools also include file cabinets and folders, each with its advantages and limitations. While file cabinets offer large storage capacity, they are bulky and inconvenient to carry. Folders are relatively lightweight, but their storage capacity is limited, and files are prone to scattering during transport due to insecure clamping, offering insufficient protection. File boxes overcome these shortcomings, providing better protection for files during transport and effectively preventing them from scattering, thus offering superior portability.

[0003] For example, Chinese utility model patent CN212219719U discloses a portable document box, including a main body. The main body includes a paper clip, an upper cover, a hinge assembly, a latch, and a lower cover. The left end of the lower cover is connected to the left end of the upper cover via the hinge assembly, and the right end of the lower cover is connected to the right end of the upper cover via the latch. The upper end of the upper cover is fixedly connected to the paper clip. A handle opening is provided on the right side of the paper clip, and the handle opening passes through the upper cover and the lower cover sequentially. In this technical solution, the latch locks the upper and lower covers, ensuring that documents will not scatter during carrying, solving the problem of insufficient sealing in traditional document storage tools. Furthermore, the added handle opening allows users to hold the document box by gripping the handle opening, improving portability. However, this solution uses a hinge assembly to connect the upper and lower covers, allowing them to rotate open or close. Because the hinge assembly protrudes from the rotating engagement surface, the file box cannot stand stably when placed and can only be laid flat. This may be inconvenient in some usage scenarios, such as when a file box needs to be temporarily placed on an office desk. Unlike some traditional file boxes, it cannot stand vertically, taking up more desktop space. Furthermore, the protruding hinge assembly is prone to scratching when in contact with other items, affecting its use. Summary of the Invention

[0004] The technical problem to be solved by this application is to provide a file box that conceals the installation of a first connector by adding a first mounting slot and a second mounting slot, so that the joint surface of the first box body and the second box body is a flat surface. The file box can be placed upright directly through this joint surface, making it more flexible to use and with higher space utilization.

[0005] This application provides a file box, including a first box body, a second box body, and a first connector. The first box body and the second box body are both rotatably connected to the first connector. The first box body and the second box body can be opened or closed relative to each other by rotating through the first connector. The first box body is provided with a first mounting groove adapted to the first connector, and the second box body is provided with a second mounting groove adapted to the first connector. The first mounting groove and the second mounting groove cooperate to accommodate the first connector, so that the mating surface of the first box body and the second box body is flush with or higher than the surface of the first connector.

[0006] In this technical solution, the first connector serves as a rotating connection component, connecting the first box and the second box together to form a separate storage cavity between them. The first and second boxes can rotate relative to each other, thereby opening or closing the storage cavity. A first mounting groove is provided on the first box, and a second mounting groove is provided on the second box. Both the first and second mounting grooves are used to install the first connector, providing a position for its installation and fixation. One side of the first connector is rotatably connected to the first mounting groove, and the other side is rotatably connected to the second mounting groove, ensuring the stability of the connection. The mating surfaces of the first and second boxes are designed to interact with the first connector. The surface of the first connector is flush with or higher than the surface of the first connector, thus forming a flat plane. This prevents the first connector from protruding from the joint surface of the first and second boxes. The joint surface refers to the surface formed after the side walls of the first and second boxes are connected by the first connector. Because the joint surface is a flat plane, the file box can be placed upright when closed, making the file box more flexible in use and storage, saving desktop space, and making the file box look simpler and more beautiful. There are no protruding parts, and the overall appearance is stronger. The first connector is hidden in the first and second mounting slots, reducing the risk of damage caused by external friction and collision, and extending the service life of the file box.

[0007] As an improvement, a third box and a second connector are also included. Both the third and second boxes are rotatably connected to the second connector, allowing them to be opened or closed relative to each other via the second connector. In this technical solution, the file box not only includes a first and second box but also adds a third box. This multi-layered structure allows the file box to hold more files or items, increasing its storage capacity. Furthermore, the second and third boxes form another independent storage cavity. This multi-layered structure can store different types of files, facilitating classification and management, and improving file management efficiency and space utilization. The third and second boxes are rotatably connected via the second connector, allowing users to flexibly open or close the third box as needed for convenient file retrieval and storage. Combined with the multi-layered structure, users can choose to open the first, second, or third box, or multiple boxes simultaneously, according to their actual needs, thereby achieving file classification and retrieval, resulting in better practicality.

[0008] As an improvement, the third housing is provided with a third mounting groove adapted to the second connector, and the second housing is provided with a fourth mounting groove adapted to the second connector. The third mounting groove and the fourth mounting groove cooperate to accommodate the second connector so that the mating surface of the third housing and the second housing is flush with or higher than the surface of the second connector. In this technical solution, the third box body is provided with a third mounting groove to accommodate a part of the second connector, and the second box body is provided with a fourth mounting groove to accommodate the other part of the second connector. One side of the second connector is rotatably connected to the third mounting groove, and the other side of the second connector is rotatably connected to the fourth mounting groove, ensuring the stability of the connection. The joint surface of the third box body and the second box body is designed to be flush with or higher than the surface of the second connector, so that the second connector will not protrude from the joint surface of the third box body and the second box body. This joint surface refers to the surface formed after the side walls of the third box body and the side walls of the second box body are connected by the second connector. Since this joint surface is a flat plane, the file box can be placed upright when closed, making the file box more flexible in use and storage, saving desktop space, and making the file box look simpler and more beautiful, without any protruding parts, with a stronger sense of unity. The second connector is hidden in the third and fourth mounting grooves, reducing the risk of damage caused by external friction and collision, and extending the service life of the file box.

[0009] As an improvement, the fourth mounting slot and the second mounting slot are the same mounting slot. In this technical solution, the second mounting slot is also configured as the fourth mounting slot. The second mounting slot is used not only to accommodate the first connecting member but also to accommodate the second connecting member. This allows the second box to be rotatably connected to both the first and third box via the second mounting slot through two connecting members. This reduces the number of mounting slots, simplifies the structural design of the second box, and ensures that the dimensions and shapes of the first and second connecting members are compatible to ensure that they can share a mounting slot without interfering with each other. This reduces the number of mounting slots, simplifies the assembly process, reduces the possibility of assembly errors, and improves production efficiency. The shared mounting slot design makes the file box structure more compact, reduces space waste, and improves the aesthetics of the file box.

[0010] As an improvement, a first rotating shaft is provided in the first mounting slot, a second rotating shaft is provided in the second mounting slot, and a first latch and a second latch are provided in the first connecting member. The first latch and the second latch are rotatably connected to the first rotating shaft, and the second latch and the second rotating shaft are rotatably connected to the second rotating shaft. In this technical solution, a first rotating shaft is provided in the first mounting slot, and a first latch is provided in the first connecting member to achieve a rotatable connection between the first connecting member and the first box body. A second rotating shaft is provided in the second mounting slot, and a second latch is provided in the first connecting member to achieve a rotatable connection between the first connecting member and the second box body. The latch design not only provides a stable connection but also allows the first connecting member to rotate freely on the rotating shaft, ensuring that the file box will not become loose or jammed during opening and closing. The design of the rotating shaft and the latch ensures the smoothness of the file box during opening and closing, allowing users to easily open or close the file box and improving ease of use.

[0011] As an improvement, the third mounting slot is provided with a third rotating shaft, the fourth mounting slot is provided with a fourth rotating shaft, and the second connector is provided with a third and a fourth buckle. The third buckle is connected to the third rotating shaft, and the fourth buckle is connected to the fourth rotating shaft. In this technical solution, the third mounting slot is provided with a third rotating shaft, and the second connector is provided with a third buckle to achieve a rotatable connection between the second connector and the third box body. The fourth mounting slot is provided with a fourth rotating shaft, and the second connector is provided with a fourth buckle to achieve a rotatable connection between the second connector and the second box body. The buckle design not only provides a stable connection but also allows the second connector to rotate freely on the rotating shaft, ensuring that the file box will not become loose or jammed during opening and closing. The design of the rotating shaft and the buckle ensures the smoothness of the file box during opening and closing, allowing users to easily open or close the file box and improving ease of use.

[0012] As an improvement, the fourth mounting slot and the second mounting slot are the same mounting slot, and the fourth rotating shaft and the second rotating shaft are the same rotating shaft. In this technical solution, the second rotating shaft is also configured as the fourth rotating shaft. This rotating shaft is used not only for connection with the second snap fastener of the first connector, but also for connection with the fourth snap fastener of the second connector. Combining the fourth rotating shaft and the second rotating shaft into a single rotating shaft reduces the number of rotating shafts and simplifies the structural design of the second box. The second snap fastener and the fourth snap fastener are arranged in a straight line on the second rotating shaft to ensure that they can share a rotating shaft without interfering with each other. Through the second rotating shaft, the first box, the second box, and the third box form a whole, and each box can be rotated to open or close relative to the other boxes. This reduces the number of rotating shafts, making the assembly process simpler and reducing the possibility of assembly errors. The shared rotating shaft design makes the structure of the file box more compact, improving the overall integrity and aesthetics of the file box.

[0013] As an improvement, a first limiting structure is provided in the first mounting slot, and a first limiting groove adapted to the first limiting structure is provided on the first connecting member. The first limiting groove cooperates with the first limiting structure to limit the rotation range of the first and second boxes. In this technical solution, the first limiting structure is provided in the first mounting slot, and the first limiting groove is provided on the first connecting member. The cooperation between the first limiting groove and the first limiting structure ensures that the first and second boxes will not rotate too much relative to each other, avoiding structural damage or inconvenience caused by excessive rotation, extending the service life of the file box. The limiting design allows users to precisely control the opening and closing angle when using the file box, avoiding inconvenience caused by excessive opening or closing.

[0014] As an improvement, a second limiting structure is provided in the third mounting slot, and a second limiting groove adapted to the second limiting structure is provided on the second connecting member. The second limiting groove cooperates with the second limiting structure to limit the rotation range of the third box and the second box. In this technical solution, the second limiting structure is provided in the third mounting slot, and the second limiting groove is provided on the second connecting member. The cooperation between the second limiting groove and the second limiting structure ensures that the third box and the second box will not rotate too much relative to each other, avoiding structural damage or inconvenience caused by excessive rotation, extending the service life of the file box. The limiting design allows users to precisely control the opening and closing angle when using the file box, avoiding inconvenience caused by excessive opening or closing.

[0015] As an improvement, the first box body is provided with a first handle, and the second box body is provided with a second handle adapted to the first handle; the first handle is provided with a fifth mounting slot, and the second handle is provided with a sixth mounting slot. A first latch is rotatably mounted in the sixth mounting slot, and a first buckle is provided in the fifth mounting slot to match the first latch. In this technical solution, a first handle and a second handle are respectively provided on the first and second boxes body. The first and second handles work together to provide a more stable carrying method. The second handle is provided with a sixth mounting slot for mounting the first latch, and a first buckle is provided in the fifth mounting slot. The first latch connects with the first buckle to keep the first and second handles in a closed and locked state, preventing the first and second boxes body from accidentally opening during carrying and ensuring document security. The first latch disengages from the first buckle to keep the first and second handles in a closed and unlocked state, allowing the first and second boxes body to rotate relative to each other and open. The first latch is rotatably mounted in the sixth mounting slot, allowing the user to easily operate the latch to achieve locking and unlocking functions.

[0016] As an improvement, the third box body is provided with a third handle that is adapted to the first handle; the second handle is provided with a seventh mounting groove, and a second latch is rotatably mounted in the seventh mounting groove; the third handle is provided with an eighth mounting groove, and a second latch is provided in the eighth mounting groove that is adapted to the second latch. In this technical solution, a third handle is provided on the third box. The shapes and sizes of the first, second, and third handles are all adapted to each other so that users can hold them simultaneously, making the multi-layered file box more convenient to carry, reducing the pressure of directly holding the file box, and providing a more stable carrying experience. A seventh mounting slot is provided on the second handle for installing the second latch, and a second latch is provided in the eighth mounting slot. The second latch connects with the second latch so that the third and second handles are in a closed and locked state, preventing the third and second boxes from being accidentally opened during carrying and ensuring the safety of the documents. The second latch disengages from the second latch so that the third and second handles are in a closed and unlocked state, and the third and second boxes can be rotated to open relative to each other. The second latch is installed in the seventh mounting slot by rotation, allowing users to easily operate the latch to achieve locking and unlocking functions.

[0030] like Figures 1 to 7As shown, this application discloses a file box, including a first box body 1, a second box body 2, and a first connecting member 3. Both the first box body 1 and the second box body 2 are rotatably connected to the first connecting member 3. The first box body 1 and the second box body 2 can be opened or closed relative to each other via the first connecting member 3. The first connecting member 3, as a rotatable connecting component, connects the first box body 1 and the second box body 2 together, forming a separate storage cavity between them. The first box body 1 and the second box body 2 can rotate relative to each other, thereby opening or closing the storage cavity. The first box body 1 is provided with a first mounting groove 11 adapted to the first connecting member 3, and the second box body 2 is provided with a mounting groove 11 adapted to the first connecting member 3. The first mounting groove 11 and the second mounting groove 21 are adapted to accommodate the first connector 3, so that the mating surfaces of the first housing 1 and the second housing 2 are flush with or higher than the surface of the first connector 3. The first mounting groove 11 is provided on the first housing 1 and the second mounting groove 21 is provided on the second housing 2. Both the first mounting groove 11 and the second mounting groove 21 are used to install the first connector 3, providing a position for the first connector 3 to be installed and fixed. One side of the first connector 3 is rotatably connected to the first mounting groove 11 and the other side of the first connector 3 is rotatably connected to the second mounting groove 21, ensuring the stability of the connection. The joint surfaces of the first box body 1 and the second box body 2 are designed to be flush with or higher than the surface of the first connector 3, thus forming a flat plane. This ensures that the first connector 3 does not protrude from the joint surface of the first box body 1 and the second box body 2. The joint surface refers to the surface formed after the side walls of the first box body 1 and the second box body 2 are connected by the first connector 3. Because the joint surface is a flat plane, the file box can be placed upright when closed, making the file box more flexible in use and storage, saving desktop space, and making the file box look simpler and more beautiful, without any protruding parts, and with a stronger sense of unity. The first connector 3 is hidden in the first mounting groove 11 and the second mounting groove 21, reducing the risk of damage caused by external friction and collision, and extending the service life of the file box.

[0031] More specifically, such as Figure 1As shown, it also includes a third box 4 and a second connecting piece 5. Both the third box 4 and the second box 2 are rotatably connected to the second connecting piece 5. The third box 4 and the second box 2 can be opened or closed relative to each other through the second connecting piece 5. The file box not only includes the first box 1 and the second box 2, but also adds a third box 4. The multi-layer structure design allows the file box to hold more files or items, increasing the storage capacity of the file box. In addition, the second box 2 and the third box 4 form another independent storage cavity. The multi-layer structure design can store different types of files, which is convenient for classification and management, improving file management efficiency and space utilization efficiency. The third box 4 and the second box 2 are rotatably connected through the second connecting piece 5. Users can flexibly open or close the third box 4 as needed, making it convenient to retrieve and store files. Combined with the multi-layer structure design, users can choose to open the first box 1, the second box 2, or the third box 4 by rotation according to actual needs, or open multiple boxes at the same time, thereby realizing the classification and retrieval of files, making it more practical.

[0032] More specifically, such as Figure 1 , Figure 3 , Figure 6 and Figure 7 As shown, the third housing 4 is provided with a third mounting groove 41 adapted to the second connector 5, and the second housing 2 is provided with a fourth mounting groove 22 adapted to the second connector 5. The third mounting groove 41 and the fourth mounting groove 22 cooperate to accommodate the second connector 5, so that the mating surfaces of the third housing 4 and the second housing 2 are flush with or higher than the surface of the second connector 5. The third housing 4 is provided with the third mounting groove 41 to accommodate a part of the second connector 5, and the second housing 2 is provided with the fourth mounting groove 22 to accommodate the other part of the second connector 5. One side of the second connector 5 is rotatably connected to the third mounting groove 41, and the other side of the second connector 5 is rotatably connected to the fourth mounting groove 22, ensuring the stability of the connection. The third housing 4 is designed accordingly. The mating surface of the second box 2 is flush with or higher than the surface of the second connector 5, so that the second connector 5 does not protrude from the mating surface of the third box 4 and the second box 2. The mating surface refers to the surface formed after the side wall of the third box 4 and the side wall of the second box 2 are connected by the second connector 5. Since the mating surface is a flat plane, the file box can be placed upright when closed, making the file box more flexible in use and storage, saving desktop space, and making the file box look simpler and more beautiful, without any protruding parts, with a stronger sense of unity. The second connector 5 is hidden in the third mounting groove 41 and the fourth mounting groove 22, reducing the risk of damage caused by external friction and collision, and extending the service life of the file box.

[0033] More specifically, such as Figure 3As shown, the fourth mounting slot 22 and the second mounting slot 21 are the same mounting slot. The second mounting slot 21 is also configured as the fourth mounting slot 22. The second mounting slot 21 is used not only to accommodate the first connecting member 3, but also to accommodate the second connecting member 5. This allows the second box body 2 to be rotatably connected to both the first box body 1 and the third box body 4 through the second mounting slot 21 via two connecting members. This reduces the number of mounting slots and simplifies the structural design of the second box body 2. The dimensions and shapes of the first connecting member 3 and the second connecting member 5 are compatible to ensure that they can share a mounting slot without interfering with each other. This reduces the number of mounting slots, making the assembly process simpler, reducing the possibility of assembly errors, and improving production efficiency. The shared mounting slot design makes the structure of the file box more compact, reduces space waste, and improves the aesthetics of the file box.

[0034] More specifically, such as Figures 2 to 5 As shown, a first rotating shaft 12 is provided in the first mounting slot 11, and a second rotating shaft 23 is provided in the second mounting slot 21. The first connecting member 3 is provided with a first buckle 31 and a second buckle 32. The first buckle 31 is rotatably connected to the first rotating shaft 12, and the second buckle 32 is rotatably connected to the second rotating shaft 23. The first rotating shaft 12 is provided in the first mounting slot 11, and the first buckle 31 is provided in the first connecting member 3 to realize the rotatable connection between the first connecting member 3 and the first box body 1. The second rotating shaft 23 is provided in the second mounting slot 21, and the second buckle 32 is provided in the first connecting member 3 to realize the rotatable connection between the first connecting member 3 and the second box body 2. The buckle design not only provides a stable connection, but also allows the first connecting member 3 to rotate freely on the rotating shaft, ensuring that the file box will not become loose or stuck during the opening and closing process. The design of the rotating shaft and the buckle ensures the smoothness of the file box during the opening and closing process, and users can easily open or close the file box, improving the convenience of use.

[0035] More specifically, such as Figure 3 , Figure 6 and Figure 7As shown, a third rotating shaft 42 is provided in the third mounting slot 41, a fourth rotating shaft 24 is provided in the fourth mounting slot 22, and a third buckle 51 and a fourth buckle 52 are provided in the second connecting member 5. The third buckle 51 is connected to the third rotating shaft 42, and the fourth buckle 52 is connected to the fourth rotating shaft 24. The third rotating shaft 42 is provided in the third mounting slot 41, and the third buckle 51 is provided in the second connecting member 5 to realize the rotational connection between the second connecting member 5 and the third box body 4. The fourth rotating shaft 24 is provided in the fourth mounting slot 22, and the fourth buckle 52 is provided in the second connecting member 5 to realize the rotational connection between the second connecting member 5 and the second box body 2. The buckle design not only provides a stable connection, but also allows the second connecting member 5 to rotate freely on the rotating shaft, ensuring that the file box will not be loose or stuck during the opening and closing process. The design of the rotating shaft and the buckle ensures the smoothness of the file box during the opening and closing process, and users can easily open or close the file box, improving the convenience of use.

[0036] More specifically, such as Figure 3 As shown, the fourth mounting slot 22 and the second mounting slot 21 are the same mounting slot, and the fourth rotating shaft 24 and the second rotating shaft 23 are the same rotating shaft. The second rotating shaft 23 is also configured as the fourth rotating shaft 24. This rotating shaft is used not only to connect with the second buckle 32 of the first connecting member 3, but also to connect with the fourth buckle 52 of the second connecting member 5. By merging the fourth rotating shaft 24 and the second rotating shaft 23 into the same rotating shaft, the number of rotating shafts is reduced, and the structural design of the second box 2 is simplified. The second buckle 32 and the fourth buckle 52 are arranged in a straight line on the second rotating shaft 23 to ensure that they can share a rotating shaft without interfering with each other. Through the second rotating shaft 23, the first box 1, the second box 2 and the third box 4 form a whole, and each box can be rotated to open or close relative to the other boxes. The number of rotating shafts is reduced, making the assembly process simpler and reducing the possibility of assembly errors. The shared rotating shaft design makes the structure of the file box more compact and improves the overall integrity and aesthetics of the file box.

[0037] More specifically, such as Figure 2 and Figure 4 As shown, a first limiting structure 13 is provided in the first mounting groove 11, and a first limiting groove 33 is provided on the first connecting member 3 to match the first limiting structure 13. The first limiting groove 33 cooperates with the first limiting structure 13 to limit the rotation range of the first box 1 and the second box 2. The first limiting structure 13 is provided in the first mounting groove 11, and the first limiting groove 33 is provided on the first connecting member 3. The cooperation between the first limiting groove 33 and the first limiting structure 13 ensures that the first box 1 and the second box 2 will not rotate too much relative to each other, avoiding structural damage or inconvenience caused by excessive rotation, and extending the service life of the file box. The limiting design allows users to precisely control the opening and closing angle when using the file box, avoiding inconvenience caused by excessive opening or closing.

[0038] More specifically, such as Figure 6 and Figure 7 As shown, a second limiting structure 43 is provided in the third mounting slot 41, and a second limiting groove 53 adapted to the second limiting structure 43 is provided on the second connecting member 5. The second limiting groove 53 cooperates with the second limiting structure 43 to limit the rotation range of the third box 4 and the second box 2. The second limiting structure 43 is provided in the third mounting slot 41, and the second limiting groove 53 is provided on the second connecting member 5.
