[0043] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0044] Please refer to Figures 1 and 2. This application provides a pivot structure 100, which includes a pivot body 10 and a mounting base 20. The pivot body 10 includes a mounting portion 11 and a functional portion 12. The mounting portion 11 is rotatably connected to the mounting base 20, and the functional portion 12 is located outside the mounting base 20. By providing the functional portion 12 located outside the mounting base 20, the pivot body 10 has the basis for expanding its functions and space. In addition to its function of being rotatably connected to the mounting base 20, the pivot body 10 can also be designed with the functional portion 12 according to requirements, thereby facilitating the expansion of other functions of the pivot body 10.

[0045] As shown in Figures 1 to 7, there are two mounting parts 11. The two ends of the functional part 12 are respectively connected to the two mounting parts 11, and the functional part 12 is bent to one side relative to the two mounting parts 11, forming a first space 13. Thus, by providing two mounting parts 11, the firmness of the assembly between the rotating shaft body 10 and the mounting base 20 is improved. Furthermore, when the two mounting parts 11 are rotatably connected to the mounting base 20, the mounting base 20 can form a limit at both ends of the functional part 12, thereby facilitating the expansion of the first space 13 and the functionality of the functional part 12. For example, the first space 13 can be used to thread a hanging rod 200, with the functional part 12 pressed onto the hanging rod 200 to function as a hook; or, the functional part 12 can also be used as a handle, in which case the first space 13 provides clearance.

[0046] Furthermore, the two mounting portions 11 are coaxially arranged, and the functional portion 12 is bent to one side relative to the axes of the two mounting portions 11 to form a semi-circular structure.

[0047] In one embodiment, the functional part 12 can be an arc-shaped semi-ring structure. Alternatively, in another embodiment, the functional part 12 can be a rectangular semi-ring structure.

[0048] In one embodiment, as shown in FIG2, the two mounting portions 11 extend relative to the functional portion 12 toward the first space 13. Thus, the rotating shaft body 10 forms an approximately closed-loop annular structure.

[0049] In another embodiment, as shown in FIG7, the two mounting portions 11 extend relative to the functional portion 12 in a direction away from the first space 13. Thus, the pivot body 10 is generally a rectangular semi-frame with protruding portions on both sides. In other embodiments, the pivot body 10 may also be generally a semi-ring with protruding portions on both sides (not shown). That is, the shape of the pivot body 10 can be approximately "Ω" or "π". It should be noted that "Ω" or "π" only describes the approximate shape of the pivot body 10, and does not mean that the shape of the pivot body 10 is exactly the same as "Ω" or "π".

[0050] Alternatively, in another embodiment, one mounting portion 11 extends relative to the functional portion 12 toward the first space 13, and the other mounting portion 11 extends relative to the functional portion 12 toward a direction away from the first space 13.

[0051] Furthermore, the functional unit 12 and the two functional units 12 are configured as an integral structure formed by bending a metal rod. The functional unit 12 and the two functional units 12 are configured as being formed by bending a single iron wire.

[0052] This application also provides a storage device 1, which includes a storage component 30 and a rotating shaft structure 100 as described in any of the above embodiments. A mounting base 20 is located on the storage component 30, and the storage component 30 is also provided with a snap-fit ​​structure 31. The functional part 12 can be sleeved on the snap-fit ​​structure 31 through the first space 13 and snap-fit ​​with the snap-fit ​​structure 31. In this way, when not in use, the functional part 12 can be fixed to the storage component 30 by snap-fit ​​with the snap-fit ​​structure 31, thereby reducing the space occupied by the functional part 12 and making the storage component 30 look neater and more beautiful.

[0053] The storage component 30 can be configured as a storage box, storage container, or other storage component 30 with internal storage space.

[0054] The mounting base 20 and the snap-fit ​​structure 31 are respectively provided on the outer wall of the storage component 30, and the snap-fit ​​structure 31 is located on one side of the mounting base 20. In this way, by flipping the pivot body 10 around the mounting base 20 to one side, the functional part 12 can be flipped to snap-fit ​​with the snap-fit ​​structure 31, or by flipping it around the mounting base 20 to the other side, the functional part 12 can be flipped to disassemble from the snap-fit ​​structure 31.

[0055] The functional part 12 is located between the two mounting parts 11 and protrudes toward the side opposite to the first space 13, forming a limiting protrusion 121.

[0056] In one embodiment, as shown in Figures 1 and 2, the limiting protrusion 121 extends in an elongated shape, and the number of the snap-fit ​​structures 31 is configured to be two, with the two snap-fit ​​structures 31 spaced apart and used to snap-fit ​​with the limiting protrusion 121 respectively.

[0057] Furthermore, the outer wall of the storage component 30 is provided with a clearance notch 35, which is located between the two snap-fit ​​structures 31. In this way, the user can hold the portion of the limiting protrusion 121 located between the two snap-fit ​​structures 31, and the clearance notch 35 is used to avoid the user's hand, thereby facilitating the user to flip the functional part 12.

[0058] In another embodiment, as shown in Figures 5 to 7, the limiting protrusion 121 may also extend in a semi-circular shape, thereby facilitating its connection with a smaller hanging rod 200.

[0059] As shown in Figure 1, the outer wall of the storage component 30 is provided with two limiting structures 36 corresponding to each functional part 12. When the functional part 12 is engaged with the snap-fit ​​structure 31, the two limiting structures 36 stop at both ends of the functional part 12 along the axial direction of the mounting base 20. In this way, the limiting structures 36 can prevent the functional part 12 from wobbling left and right when it is engaged with the snap-fit ​​structure 31.

[0060] As shown in Figure 2, the storage component 30 includes an upper cover 33 and a lower cover 34 that interlock with each other. The upper cover 33 and the lower cover 34 are used to enclose and form a storage space for the storage component 30.

[0061] In one embodiment, as shown in FIG2, the mounting base 20 is disposed at the junction of the upper cover 33 and the lower cover 34, and the upper cover 33 and the lower cover 34 are hinged by the pivot body 10, and the snap-fit ​​structure 31 is disposed on one of the upper cover 33 and the lower cover 34. In this case, the mounting pivot body 10 also serves as a hinge shaft connecting the upper cover 33 and the lower cover 34.

[0062] In another embodiment, as shown in FIG10, the mounting base 20 is provided on one of the upper cover 33 and the lower cover 34, and the snap-fit ​​structure 31 is provided on the other of the upper cover 33 and the lower cover 34. In this case, when the functional part 12 engages with the snap-fit ​​structure 31, the mounting shaft body 10 can also lock the upper cover 33 and the lower cover 34.

[0063] In one embodiment, referring to Figures 5 to 7, two mounting portions 11 extend relative to the functional portion 12 in a direction away from the first space 13. Each mounting portion 11 includes a first segment 14 and a second segment 15. The first segment 14 is fixedly connected to the functional portion 12, and the second segment 15 is detachably connected to the first segment 14. The second segment 15 serves to extend the mounting portion 11, thus facilitating the matching of mounting portions 11 with mounting bases 20 of different lengths.

[0064] Further, in one embodiment, the mounting base 20 includes a first mounting base 21 and a second mounting base 22, which are disposed on different sides of the storage member 30 along its circumference. The rotating shaft body 10 is mounted on the first mounting base 21, and the functional part 12 can be detached from the first mounting base 21 together with the first segment 14, and rotatably connected to the second mounting base 22 via the first segment 14. Thus, by splitting the same rotating shaft body 10, the mounting position can be changed on mounting bases 20 of different sizes for the same storage member 30, and the functional part 12 allows the storage member 30 to be hooked from different sides. In one embodiment, the length of the side where the first mounting base 21 is located is greater than the length of the side where the second mounting base 22 is located.

[0065] Furthermore, the storage component 30 includes an upper cover 33 and a lower cover 34 that interlock. A first mounting base 21 is located at the junction of the upper cover 33 and the lower cover 34. The upper cover 33 and the lower cover 34 are hinged together by a second segment 15. A second mounting base 22 is located on one of the upper cover 33 and the lower cover 34. Thus, when the pivot body 10 is mounted on the first mounting base 21, both the first segment 14 and the second segment 15 serve as hinge shafts for hinged upper cover 33 and lower cover 34, and the functional part 12 can be used as a hook or a handle. When the functional part 12 is detached from the first mounting base 21 along with the first segment 14 and is rotatably connected to the second mounting base 22 via the first segment 14, the second segment 15 still serves as a hinge shaft for hinged upper cover 33 and lower cover 34, and the functional part 12 can be used as a hook or a handle at the second mounting base 22.

[0066] As shown in Figure 8, multiple storage components 30 are configured. Each storage component 30 is rotatably mounted with a rotating shaft body 10 via a corresponding mounting base 20, and each storage component 30 is provided with a snap-fit ​​structure 31. The multiple storage components 30 are stacked, and the functional part 12 on each storage component 30 can snap into the snap-fit ​​structure 31 on the adjacent storage component 30. Thus, when multiple storage components 30 are stacked, the functional part 12 snaps into the snap-fit ​​structure 31 on the adjacent storage component 30, thereby firmly connecting the stacked storage components 30 together.

[0067] In one embodiment, referring to Figures 3 and 4, multiple storage components 30 are stacked along their own height direction. Each storage component 30 has a stacking structure 23 on its top wall and a stacking engagement structure 24 on its bottom wall. The stacking structure 23 of each storage component 30 and the stacking engagement structure 24 of the storage component 30 above it engage in a snap-fit ​​configuration. It is understood that by providing the stacking structure 23 and the stacking engagement structure 24, the stability of the stacking of each storage component 30 and the storage component 30 above it can be improved, thus preventing the storage component 30 above it from falling off.

[0068] In one embodiment, one of the stacking structure 23 and the stacking mating structure 24 is configured as a protrusion 241, and the other is configured as a recess 231. This facilitates quick and easy snapping of the corresponding stacking structure 23 and stacking mating structure 24 together. Furthermore, the protrusion 241 is inserted into the corresponding recess 231 along the height direction of the receiving member 30.

[0069] In one embodiment, the number of protrusions 241 is configured to be multiple, and the multiple protrusions 241 are distributed at intervals on the top wall of the receiving member 30. Furthermore, the distribution of the protrusions 241 at intervals on the top wall of the receiving member 30 is beneficial to make the receiving member 30 more evenly stressed.

[0070] In other embodiments, one of the stacked structure 23 and the stacked mating structure 24 may be configured as a snap-fit ​​and the other as a slot, with the two achieving quick connection and separation through elastic deformation.

[0071] As shown in Figure 8, in one embodiment, multiple storage components 30 are of the same size and are stacked one by one along a preset direction. The preset direction of the storage component 30 can be the height direction Z of the storage component 30, and the functional part 12 of each storage component 30 engages with the snap-fit ​​structure 31 on the storage component 30 located above it along the height direction Z.

[0072] Referring to Figure 9, the multiple storage components 30 can also have different sizes; that is, the multiple storage components 30 can have at least two sizes. Thus, the multiple storage components 30 can be divided into large-sized storage components 30 and small-sized storage components 30 based on their relative sizes. The large-sized storage component 30 has multiple stacking positions 32, each stacking position 32 being used to place a corresponding small-sized storage component 30. Each large-sized storage component 30 is equipped with a pivot body 10 corresponding to each stacking position 32, and each pivot body 10 is used to engage with the corresponding snap-fit ​​structure 31 of the small-sized storage component 30. It should be noted that when multiple storage components 30 are stacked along their height direction Z, different sizes mean that the widths and / or lengths of the multiple storage components 30 are different. Thus, a single large-sized storage component 30 can simultaneously stack and connect multiple small-sized storage components 30.

[0073] It is understandable that the large-sized storage component 30 and the small-sized storage component 30 are distinguished and named after comparing the sizes of two storage components 30. When multiple storage components 30 have three or more sizes, the same storage component 30 can be defined as a large-sized storage component 30 relative to another storage component 30 that is smaller in size, and as a small-sized storage component 30 relative to another storage component 30 that is larger in size. In other words, depending on the size comparison object, each storage component 30 can be either a small-sized storage component 30 or a large-sized storage component 30.

[0074] As shown in Figures 9 and 10, the large-sized storage component 30 includes an upper cover 33 and a lower cover 34 that interlock with each other. Multiple pivot bodies 10 are arranged along the circumference of the storage component 30 on different sides of the storage component 30. One of the pivot bodies 10 is rotatably mounted at the junction of the upper cover 33 and the lower cover 34 through a corresponding mounting base 20, thereby hinged the upper cover 33 and the lower cover 34. The other pivot bodies 10 are rotatably mounted on one of the upper cover 33 and the lower cover 34 through corresponding mounting bases 20. Thus, the pivot body 10, which is rotatably mounted on the upper cover 33 or the lower cover 34, is used to fix the small-sized storage piece 30 to the stacking position 32. Furthermore, the pivot body 10, located at the junction of the upper cover 33 and the lower cover 34, not only fixes the small-sized storage piece 30 to the stacking position 32, but also serves as a hinge shaft connecting the upper cover 33 and the lower cover 34, thereby allowing the upper cover 33 or the lower cover 34 of the large-sized storage piece 30 to rotate around the pivot body 10, so as to facilitate opening or closing the large-sized storage piece 30.

[0075] In one embodiment, as shown in Figures 11 and 12, two storage components 30 of different sizes are stacked along the height direction Z. Further, the storage component 30 includes a first storage component 301 and a second storage component 302. The width of the second storage component 302 is greater than the width of the first storage component 301. The second storage component 302 has two second stacking positions 322 distributed along the width direction Y. A second rotating shaft body 102 is rotatably mounted on each of the two ends of the second storage component 302 along the width direction Y. Each second stacking position 322 is used to place a first storage component 301, and each second rotating shaft body 102 is used to engage with the corresponding snap-fit ​​structure 31 of a first storage component 301.

[0076] In another embodiment, as shown in Figures 11 and 12, three different sized storage components 30 can be stacked along the height direction Z. Further, the storage component 30 also includes a third storage component 303, the length of which is greater than the length of the second storage component 302, and the width of the second storage component 302 is greater than the width of the first storage component 301. The first storage component 301 has two first stacking positions 321 distributed along the length direction X, and two first rotating shaft bodies 101 are rotatably mounted on the side of the first storage component 301 along the length direction X. Each first stacking position 321 is used to place one second storage component 302, and each first rotating shaft body 101 is used to engage with the corresponding second storage component 302's snap-fit ​​structure 31.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
