[0034] Example 1: As shown in the attached document Figure 1 To be continued Figure 3 As shown, a modular storage device includes a central support column 1, two rotating storage units 2, a top fixed cover 3, and a bottom fixed cover 4.

[0035] The central support column 1 is vertically arranged and includes a longitudinally arranged main body, an upper connecting end, and a lower connecting end. The main body, the upper connecting end, and the lower connecting end are all circular tube structures with cavities. The upper connecting end is coaxially arranged at the upper end of the main body, and the lower connecting end is coaxially arranged at the lower end of the main body. The outer diameters of the upper connecting end and the lower connecting end are both smaller than the outer diameter of the main body.

[0036] The rotating storage unit 2 includes a rotating disk 5, a rotating central bearing 6, and multiple storage boxes 7. The rotating disk 5 can be a circular disk structure with a through hole in its center, and is fitted around the outer periphery of the central support column 1. In this embodiment, a sleeve 8 is provided at the center of the rotating disk 5, i.e., at the circumference of the through hole. The axial direction of the sleeve 8 is perpendicular to the disk surface of the rotating disk 5, and the central support column 1 passes through the sleeve 8. The rotating central bearing 6 connects the central support column 1 and the rotating disk 5, and is used to rotatably connect the central support column 1 and the rotating disk 5, so that the rotating disk 5 can rotate about the central support column 1 as its axis. In this embodiment, the sleeve 8 on the rotating disk 5 includes a small-diameter portion and a large-diameter portion connected in series axially. The inner diameter of the large-diameter portion is larger than the inner diameter of the small-diameter portion, thus forming a stepped hole, and the rotating central bearing 6 is disposed within the large-diameter portion. The two rotating storage units 2 are arranged parallel to each other at a certain interval along the axial direction of the central support column 1. Typically, the rotating disk 5 is located at the lower or upper connecting end of the central support column 1, meaning the rotating central bearing 6 is also located at the lower or upper connecting end of the central support column 1. In this embodiment, the two rotating storage units 2 are respectively located at the lower and upper connecting ends of the central support column 1, and the length of the main body of the central support column 1 constitutes the distance between the two rotating storage units 2.

[0037] Multiple storage boxes 7 can be detachably mounted on the rotating disk 5. Each storage box 7 includes a separate box body 9 and a lid 10. The box body 9 has a storage space for holding items, and the lid 10 covers the opening of this storage space. A connecting strip 11 can be provided between the box body 9 and the lid 10 to connect them; the connecting strip 11 is located on the outside of both the box body 9 and the lid 10. A latch 12 is provided on the box body 9 to secure the lid 10 when it is closed. The lid 10 has a temporary placement area 13 on its outside for temporarily placing items. If the storage box 7 is used to hold magnetic metal items, a magnet can be embedded in the temporary placement area 13 to attract items and prevent them from slipping out. A luminous label or embossed mark can be provided on the lid 10 or the box body 9 to identify items, making it easy to identify items in the storage box 7 even in dark environments. In this embodiment, a luminous label is used, which is placed at a suitable position on the box body 9 and embedded in the groove 14.

[0038] Since the rotating disk 5 is circular, the storage boxes 7 used in this embodiment are approximately fan-shaped, and multiple storage boxes 7 are arranged in a ring on the rotating disk 5. In this embodiment, the central angle corresponding to each storage box 7 is approximately 45°, and eight storage boxes 7 can be set on each layer of the rotating disk 5. Furthermore, a sliding connection mechanism is provided between the storage boxes 7 and the rotating disk 5. Specifically, a guide rail is provided on the rotating disk 5, and a guide groove is provided on the box body 9 of the storage box 7. When the storage box 7 is installed on the rotating disk 5, the guide rail slides in the guide groove. In this embodiment, to match the fan-shaped storage box 7, the guide rail is arranged radially along the rotating disk 5. Each storage box 7 can be matched with multiple guide rails and has multiple guide grooves. For example, multiple spacer strips 19 are vertically arranged on the rotating disk 5, each spacer strip 19 is located between two adjacent storage boxes 7, the spacer strip 19 is arranged radially along the rotating disk 5, and its height is approximately half the height of the storage box 7. At this time, the guide rails include a side guide rail 15 disposed at the top of the spacer 19 and a bottom guide rail 16 disposed on the rotating disk 5, with the bottom guide rail 16 located in the space between the spacer 19; the guide groove side includes a side guide groove 17 disposed on the side of the box body 9 and a bottom guide groove 18 disposed at the bottom of the box body 9, wherein there are two side guide grooves 17, respectively located on both sides of the box body 9 and corresponding to the two side guide rails 15 at the top of the spacer 19 on both sides of the box body 9. The side guide rails 15 are slidably engaged with the side guide grooves 17, and the bottom guide rails 16 are slidably engaged with the bottom guide grooves 18. When installing the storage box 7, simply slide the storage box 7 into place radially towards the center of the rotating disk 5.

[0039] The top fixing cover 3 is embedded in the upper connecting end of the central support column 1, and the bottom fixing cover 4 is embedded in the lower connecting end of the central support column 1. Internal threads can be provided on the lower connecting end and the upper connecting end of the central support column 1, while external threads are provided on both the top fixing cover 3 and the bottom fixing cover 4. The internal thread of the lower connecting end matches the external thread of the bottom fixing cover 4 to achieve a spiral embedding of the bottom fixing cover 4, and the internal thread of the upper connecting end matches the external thread of the top fixing cover 3 to achieve a spiral embedding of the top fixing cover 3. The top fixing cover 3 includes a top cover connecting part embedded in the upper connecting end and a top cover body located at one end of the top cover connecting part. The outer diameter of the top cover body is larger than the outer diameter of the top cover connecting part. After the top fixing cover 3 is installed, the top cover connecting part is embedded in the upper connecting end, and the top cover body abuts against the end face of the upper connecting end. The bottom fixing cover 4 includes a bottom cover connecting part embedded in the lower connecting end and a bottom cover body located at one end of the bottom cover connecting part. The outer diameter of the bottom cover body is larger than the outer diameter of the bottom cover connecting part. After the bottom fixing cover 4 is installed, the bottom cover connecting part is embedded in the lower connecting end, and the bottom cover body is pressed against the end face of the lower connecting end.

[0040] Example 2: As shown in the attached document Figure 4 To be continued Figure 6 As shown, a modular storage device includes three central support columns 1, four rotating storage units 2, a top fixing cover 3, and a bottom fixing cover 4. The central support columns 1 are coaxially connected in series, and in any two adjacent central support columns 1, the lower connecting end of the upper central support column 1 is embedded in the upper connecting end of the lower central support column 1. The lower connecting end of the central support column 1 may also be provided with an external thread, so that the external thread of the lower connecting end matches the internal thread of the upper connecting end, thereby allowing the lower connecting end of the upper central support column 1 to be spirally embedded into the upper connecting end of the lower central support column 1. The four spiral storage units are all located at the rotating central bearing 6, which is positioned at either the lower or upper connecting end of the central support column 1, and their structure is the same as in Embodiment 1. The top fixing cover 3 is screwed into the upper connecting end of the uppermost central support column 1, and the bottom fixing cover 4 is screwed into the lower connecting end of the lowermost central support column 1.

[0041] As can be seen from the above embodiments, the modular storage device involved in this application may include n (n is a positive integer) vertically arranged central support columns 1, n+1 rotating storage units 2, a top fixed cover 3, and a bottom fixed cover 4. The rotating storage units 2 can rotate freely 360° around the central support column 1 as the axis, and the rotating storage units 2 of each layer do not interfere with each other during rotation. Typically, each modular storage device has 3-5 independent rotating disks 5. If more layers are needed, corresponding central support columns 1 and rotating storage units 2 can be added freely.

[0042] The storage box 7 can be made of transparent PC material and injection molded. The injection mold for the entire device requires only three core components: the storage box mold, the rotating disk mold, and the central support column mold. The top fixing cover 3 and the bottom fixing cover 4 can be 3D printed, saving mold opening cycle and cost. The rotating central bearing 6 can be directly purchased as a mature standard part.

[0043] One application example is the use of the modular storage device described above to store screws of various specifications required for the production line. Existing screw storage boxes 7 require manual retrieval and searching by workers, lacking temporary storage areas, magnetic areas for temporarily placing screws to be categorized, or buffer compartments. They typically only allow categorization by screw size, not by material (steel / copper / stainless steel), application (electronic / mechanical / furniture), or thread type (self-tapping / machine thread). There is no tactile / visual assistance, making blind operation impossible in dark environments (no raised markings or luminous partitions). However, with the modular storage device of this invention, the storage box 7 can be moved by rotating the rotating disk 5, enabling quick location and search of the target screw section, improving operational efficiency. Long screw rods can also be placed inside the central support column 1, increasing the storage capacity. The box body 9 and the lid 10 are fixed by a snap-fit ​​structure 12, which can be opened and closed by pressing the snap-fit ​​12 with the thumb, allowing for one-handed operation and compatibility with M1-M12 screws or different parts. The lid 10 has a built-in strong magnet area that can temporarily attract screws to be categorized. The box body has 14 luminous labels affixed to the grooves on the front to provide illumination, allowing for easy identification of screw types in low-light conditions. The device is also easy for users to disassemble, requiring no tools for maintenance; specific parts can be removed as needed without disassembling the entire structure.

[0044] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
