Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gasket boxes, in particular to a gasket box layered structure. BACKGROUND

[0002] The gasket box, as a kind of packaging appliance, is widely used in logistics, medicine and other fields. It is mainly composed of a bottom support and a plurality of gaskets assembled on the upper part of the bottom support. The bottom support constitutes the bottom wall of the gasket box, and all the gaskets are connected in sequence along the circumference of the bottom support to constitute the peripheral wall of the gasket box. The receiving space for containing articles is formed by the combination of the peripheral wall and the bottom wall.

[0003] Among them, each gasket is detachably connected or hingedly connected. In this way, when the gasket box is not used, each gasket can be detached from the bottom support. If the gaskets are hingedly connected, the detached gaskets are folded and stacked vertically. If the gaskets are detachable, each gasket is detached and then stacked vertically. In this way, the floor space of the gaskets is reduced, and the entire gasket box can be stored in a folded or stacked state when idle to reduce the storage space.

[0004] In related technologies, in order to make the gasket box have a layered function, some gasket boxes also include a layer plate. The layer plate is detachably erected in the receiving space of the gasket box, so that the receiving space forms two independent spaces above and below under the separation of the layer plate.

[0005] For the existing layered gasket box, in order to be able to erect the layer plate, a supporting part protruding from the inner side wall of the gasket is generally designed on the inner side wall of the gasket. The supporting part is mainly used to support the layer plate so that the layer plate is erected in the receiving space.

[0006] However, for the gasket box with the supporting part, the erection of the layer plate can be realized, but it also brings some problems. For example, since the supporting part protrudes from the inner side wall of the gasket, when the gaskets are stacked after being detached, the plate surfaces of the two layers of gaskets cannot be fitted due to the presence of the supporting part, thereby making the stacking unstable. Moreover, such stacking is easy to damage the supporting part, and thus needs to be improved. SUMMARY

[0020] When the layered structure provided by this solution is applied to the use of the panel box, the supporting part can flip between the storage position and the unfolded position relative to the fixed part. Therefore, after the panel box is assembled, the supporting part enters the unfolded position, so that it at least partially protrudes from the inner surface of the panel to support the shelves, thus enabling the layering of the panel box. When the panel box is not in use and the panels need to be disassembled for stacking, the supporting part can enter the storage position. At this time, the entire layered structure does not protrude from the surface of the panel, which is equivalent to making the surface of the panel without any protruding parts. This ensures that when two panels are stacked, the layered structure will not interfere with them, allowing the panels to be pressed together. This ensures the stability of the panels when stacked, and the panels will not squeeze the layered structure during the stacking process, which helps to protect the layered structure.

[0021] Furthermore, in this solution, the support part is linked to the assembly process of the enclosure panels. That is, during the assembly of the enclosure panels, the support part automatically enters the unfolded position, and when the enclosure panels are disassembled, the support part automatically enters the storage position. This allows the support part to move between the unfolded and storage positions without any additional human intervention. It can be carried out automatically during the assembly and disassembly of the enclosure panels, which is ingeniously designed and saves on operation steps. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0034] In the following description, terms such as “inner,” “outer,” “upper,” “lower,” “left,” and “right” that indicate orientation or positional relationship are used only for the convenience of describing the embodiments and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0035] The present invention aims to solve the problem of how to design a layered structure and a panel box, so that when the panel box is assembled, the layered structure can be used to support the panels, and when the panel box is disassembled, the layered structure will not interfere with the stacking of the panels.

[0036] Based on this, the present invention provides a layered structure for a panel box, applied to a panel box, wherein the peripheral wall of the panel box is composed of a plurality of panels that are detachably connected in sequence along the circumferential direction; wherein the layered structure is used to support the layered panel between two adjacent panels, the layered structure includes a fixing part, a supporting part, and a linkage component, the fixing part is used to fix to the panel, the supporting part is rotatable relative to the fixing part between a stowed position and an unfolded position; in the stowed position, the supporting part is close to the fixing part so that the entire layered structure does not protrude from the surface of the panel; in the unfolded position, the supporting part at least partially protrudes from the inner side of the panel to support the layered panel; the linkage component is configured such that when two adjacent panels are in an assembled state, the linkage component drives the supporting part to automatically enter the unfolded position, and when two adjacent panels are separated, the linkage component drives the supporting part to automatically enter the stowed position.

[0037] Example 1

[0038] Reference Figures 1-11As shown, this embodiment provides a layered structure for a enclosure box, wherein the enclosure box includes a plurality of enclosure panels connected in sequence, and each enclosure panel encloses and forms the perimeter wall of the enclosure box. Of course, the enclosure box may also include a bottom support 10, which is detachably connected to the bottom of each enclosure panel to serve as the bottom wall of the enclosure box.

[0039] The number of enclosure panels is selected according to actual needs. For example, in some embodiments, the enclosure panels include four sets, which are opposite each other in pairs to form a rectangular frame structure as the perimeter wall of the enclosure box.

[0040] For ease of explanation, in this embodiment, as... Figure 1 As shown, one of the two adjacent enclosures is designated as the first enclosure 11 and the other as the second enclosure 12. Taking a rectangular enclosure box as an example, it includes two oppositely arranged first enclosures 11 and two oppositely arranged second enclosures 12.

[0041] In some embodiments, such as Figure 2 As shown, both first enclosure panels 11 are provided with layered structures, and symmetrically arranged layered structures are provided on both sides of the same first enclosure panel 11. This is equivalent to making the assembled enclosure box have 4 layered structures to support the layered panels 13 at the four corners near the enclosure box.

[0042] Shelves 13 are mainly used to divide the space inside the box and serve as a carrier for carrying items, so that the inside of the box can form two layers of space to store items.

[0043] Since the structures of each layer are basically the same, this embodiment will use one of them as an example for specific explanation.

[0044] like Figure 2 As shown, the layered structure includes a fixing part 2, a supporting part 3, and a linkage component 4.

[0045] The fixing part 2 is used to fix it to the enclosure panel. The supporting part 3 can be flipped relative to the fixing part 2 between the storage position and the unfolded position. For example, in some embodiments, the lower end of the supporting part 3 is rotatably connected to the lower part of the fixing part 2, and its upper end can be freely flipped relative to the fixing part 2 to realize the switching between the storage position and the unfolded position.

[0046] like Figure 3 As shown, when the supporting part 3 is in the storage position, the supporting part 3 is brought together with the fixing part 2 so that the entire layered structure does not protrude from the surface of the enclosure.

[0047] It is worth noting that the surface of the partition panel here includes both the inner and outer sides of the partition panel, that is, the surfaces on both sides of the partition panel. This ensures that when the partition panel is in the storage position, the entire layered structure does not protrude from the surface of the partition panel, making the surface of the partition panel basically without any protruding parts. This ensures that when the two partition panels are stacked, the surfaces of the upper and lower partition panels can basically fit together, which helps to ensure the stability of the partition panel stack. Moreover, at this time, the layered structure is basically not squeezed by the stacked partition panels, which helps to protect the layered structure.

[0048] The following description uses the example of the fixing part 2 being installed on the first enclosure 11. In order to prevent the layered structure from protruding from the surface of the first enclosure 11, in some embodiments, such as... Figure 10 and 1 Figure 11 As shown, mounting grooves 112 for accommodating the layered structure are provided on both sides of the inner surface of the first enclosure 11. The mounting grooves 112 are opened on the side near the second enclosure 12. The depth of the mounting grooves 112 is configured such that when the support part 3 is in the storage position, the entire layered structure does not protrude from the inner surface of the first enclosure 11.

[0049] Furthermore, in order to ensure that the supporting part 3 can be better aligned with the fixing part 2, thereby reducing the thickness of the entire layered structure when the supporting part 3 is in the retracted position, in this embodiment, as follows: Figure 5 As shown, both the fixing part 2 and the supporting part 3 are U-shaped. The supporting part 3 is rotatably connected within the U-shaped space inside the fixing part 2. When the supporting part 3 is in the retracted position, as shown... Figure 3 and Figure 7 As shown, the supporting part 3 is housed within the fixing part 2, preferably both of which are in a vertical position.

[0050] like Figure 4 As shown, in the unfolded position, the support part 3 at least partially protrudes from the inner side of the first enclosure 11 to support the shelf 13. In some embodiments, the upper end of the support part 3 flips out from the mounting groove 112 to protrude from the inner side of the first enclosure 11. In this case, the protruding part can serve as a carrier for placing the shelf 13. (Refer to...) Figure 2 As shown.

[0051] The supporting part 3 is linked to the assembly and disassembly of the surrounding panel through the linkage component 4. The linkage component 4 is constructed as follows: taking the adjacent first surrounding panel 11 and second surrounding panel 12 as an example, when the first surrounding panel 11 and the second surrounding panel 12 are in the assembled state, the linkage component 4 drives the supporting part 3 to automatically enter the unfolded position. When the two adjacent surrounding panels are disassembled, the linkage component 4 drives the supporting part 3 to automatically enter the storage position.

[0052] Specifically, during the assembly of the first panel 11 and the second panel 12, the supporting part 3 automatically enters the unfolded position, and when the panels are disassembled, the supporting part 3 can automatically enter the storage position. This allows the supporting part 3 to move between the unfolded and storage positions without any additional human operation. It can be carried out automatically during the assembly and disassembly of the panels. The design is ingenious and saves operation steps.

[0053] like Figure 2 As shown, the assembly method for the first enclosure 11 and the second enclosure 12 can be that the two are assembled by vertically interlocking with each other. For example, the end of the first enclosure 11 is provided with a vertically extending tenon 111, and the inner surface edge of the second enclosure 12 is provided with a vertically extending mortise 121 that is adapted to the tenon 111 for vertical interlocking.

[0054] To achieve linkage between the enclosure and the supporting part 3, in some embodiments, such as Figure 3 and Figure 4 As shown, the linkage component 4 includes a swing arm 41 and an elastic element 43. The upper end of the swing arm 41 is rotatably connected to the side wall of the fixed part 2 near the second enclosure 12. The rotation axis of the swing arm 41 is parallel to the flipping axis of the support part 3.

[0055] In some embodiments, the elastic element 43 may be one or more of a spring, elastic band, or sheet, and is mainly used to apply elastic force to the swing arm 41 to cause the support portion 3 to return to its retracted position.

[0056] Thanks to the U-shaped structure of the support part 3, there is a hollow space between the support part 3 and the fixing part 2 when the support part 3 is in the storage position. This space can be used as a space for installing the elastic element 43. Taking a spring as the elastic element 43 as an example, the spring is a tension spring, with one end fixed to the fixing part 2 and the other end fixed to the support part 3.

[0057] In addition, the swing arm 41 is also linked with the support part 3, for example, as Figure 4 As shown, the swing arm 41 is provided with a first guide groove 411 extending along the length direction of the swing arm 41, and the support part 3 is provided with a first guide part 31 that moves synchronously with the support part 3.

[0058] The first guide part 31 is at least partially movable through the first guide groove 411. The cooperation between the first guide part 31 and the first guide groove 411 enables the linkage between the support part 3 and the swing arm 41. Thus, when the swing arm 41 is rotated, the first guide part 31 is pushed by the side wall of the first guide groove 411, which in turn pushes the support part 3 to rotate, and the first guide part 31 moves along the first guide groove 411.

[0059] In order to enable the first guide part 31 to move more smoothly in the first guide groove 411, the first guide part 31 may adopt a rotatable first guide wheel, which is disposed in the first guide groove 411 and can roll in the first guide groove 411.

[0060] In addition, such as Figure 3 and Figure 4 As shown, in order to avoid the movement of the first guide part 31, an arc-shaped clearance opening 21 is provided on the side wall of the fixing part 2 for the first guide part 31 to pass through.

[0061] The loading / unloading linkage between the swing arm 41 and the side panel is as follows:

[0062] When adjacent first enclosure 11 and second enclosure 12 are vertically inserted and assembled together, the second enclosure 12 applies a force to the swing arm 41 to drive the swing arm 41 to rotate in the first direction. The direction opposite to the first direction is referred to as the second direction. For example, with... Figure 7 Taking the shown perspective as an example, the first direction is clockwise and the second direction is counterclockwise.

[0063] When the swing arm 41 flips in the first direction, it pushes the first guide 31, along with the support 3, causing the support 3 to overcome the elastic force of the elastic member 43 and flip in the second direction, ultimately bringing the support 3 into the unfolded position (e.g., Figure 8 and Figure 9 (as shown in the diagram), thus achieving the aforementioned goal that when two adjacent panels are in a phase assembly state, the linkage component 4 drives the support part 3 to automatically enter the unfolded position.

[0064] When the adjacent first enclosure 11 and second enclosure 12 separate from each other, the second enclosure 12 releases the force on the swing arm 41, thereby causing the supporting part 3 to return to the storage position under the elastic force of the elastic member 43. During the reset process, the supporting part 3 drives the swing arm 41 to rotate in the second direction. In this way, the supporting part 3 automatically enters the storage position when the enclosures separate from each other, as mentioned above.

[0065] In order to achieve the linkage between the swing arm 41 and the second enclosure 12, in this embodiment, as follows: Figure 3 and Figure 4 As shown, the swing arm 41 is also provided with a second guide groove 412, which, when the support part 3 is in the retracted position, such as Figure 9 As shown, the second guide groove 412 is in an inclined state.

[0066] The fixing part 2 is provided with a second guide part 44 that can move vertically relative to the fixing part 2, for example:

[0067] like Figure 6As shown, the fixed part 2 has a vertically extending groove 22 on the side wall near the swing arm 41. A slider 221 is slidably connected in the groove 22. The groove 22 and the slider 221 are adapted to each other. The groove 22 can be a dovetail groove 22 structure or an inverted trapezoidal groove 22 structure, so that the slider 221 can only slide up and down along the groove 22 and will not fall out of the groove 22. The second guide part 44 is fixed on the slider 221; thus realizing the vertical movement of the second guide part 44.

[0068] The second guide portion 44 is at least partially movably inserted into the second guide groove 412. For example, in order to enable the second guide portion 44 to move smoothly in the second guide groove 412, in this embodiment, the part of the second guide portion 44 that inserts into the second guide groove 412 is a rotatable second guide wheel 440.

[0069] Furthermore, the second guide section 44 at least partially constitutes a trigger section. When the adjacent first enclosure 11 and second enclosure 12 are assembled together, the second enclosure 12 provides at least one downward force to push the trigger section. The trigger section moves downward under the push of the second enclosure 12, thereby causing the second guide section 44 to slide downward as a whole. In this way, the second guide section 44 will push the swing arm 41 to rotate in the first direction in the second guide groove 412. The rotation of the swing arm 41 in the first direction can push the support section 3 to move to the unfolded position.

[0070] The specific linkage structure between the trigger segment and the second enclosure 12 is as follows:

[0071] Combination Figure 1 , Figure 10 , Figure 11 As shown, a slot 122 extending vertically is provided on the inner sidewall of the second enclosure 12, wherein the lower end of the slot 122 penetrates the bottom wall of the second enclosure 12 to serve as an entry point for the trigger segment to be inserted into the slot 122.

[0072] The slot 122 includes a pressing surface 123. For example, the upper end of the slot 122 is closed, and the pressing surface 123 is formed by the upper end wall of the slot 122.

[0073] like Figure 10 As shown, the second guide portion 44 extends toward the second enclosure 12 and is at least partially inserted into the slot 122 to form the trigger segment, which is movable vertically in the slot 122; the pressing surface 123 is located above the trigger segment and is used to push the trigger segment downward when the first enclosure 11 and the second enclosure 12 are inserted into each other.

[0074] Specifically, when the first enclosure 11 and the second enclosure 12 are vertically inserted, the trigger segment first enters the slot 122 through the inlet. As the second enclosure 12 continues to be inserted downwards, the trigger segment and the pressing surface 123 gradually approach each other. After the second enclosure 12 is inserted to a certain distance, the pressing surface 123 begins to contact the trigger segment. Then, as the second enclosure 12 continues to be inserted downwards, the pressing surface 123 begins to press the trigger segment downwards, thereby driving the trigger segment and the second guide part 44 to move downwards as a whole, and finally flipping the support part 3 to the unfolded position.

[0075] In this embodiment, as Figure 8 and Figure 9 As shown, the unfolding positions include a first unfolding position and a second unfolding position. When the supporting part 3 rotates counterclockwise, it first passes through the first unfolding position (e.g., ...). Figure 8 (as shown in the diagram), and then from the first unfolded position to the second unfolded position (as shown in the diagram). Figure 9 (as shown in the figure), so that the supporting part 3 protrudes more from the inner side of the panel in the second unfolded position than in the first unfolded position.

[0076] When the first enclosure 11 and the second enclosure 12 are inserted into each other, that is, when the second enclosure 12 is inserted to its maximum distance relative to the first enclosure 11 (for example, when the lower end of the second enclosure 12 contacts the base 10), at this time, as Figure 8 As shown, the support part 3 is in the first unfolded position, and the pressing surface 123 is in a state of pressing against the trigger section; moreover, at this time, the slider 221 still has space to slide down in the slide groove 22.

[0077] When the supporting part 3 bears weight in the first unfolded position, for example, Figure 9 As shown, when the shelf 13 is placed on the support part 3 in the first unfolded position, the support part 3 will be pushed to rotate counterclockwise under the weight of the shelf 13 and eventually enter the second unfolded position. In order to support the shelf 13 more stably, the upper end of the support part 3 is constructed such that when the support part 3 is in the second unfolded position, the upper end of the support part 3 is in a horizontal state. In this way, the shelf 13 is supported by the horizontal upper end, which is more stable.

[0078] Moreover, as the supporting part 3 flips from the first unfolded position to the second unfolded position, it will drive the swing arm 41 to continue to flip along the first direction, thereby pushing the second guide part 44 and the slider 221 downward, so that the slider 221 abuts against the bottom wall of the groove 22 and the slider 221 enters the end position.

[0079] At the final position, since the slider 221 is blocked by the bottom wall of the slide 22, the slider 221 cannot continue to slide down or descend, thus restricting the swing arm 41 from continuing to rotate in the first direction. This restriction of the swing arm 41 also restricts the support part 3, preventing it from rotating counterclockwise. In other words, it restricts the support part 3 from continuing to rotate away from the storage position from the second unfolded position. Thus, the support part 3 can support the shelf 13 in the second unfolded position. At this point, it is equivalent to the swing arm 41 pulling the support part 3 to maintain it in the second unfolded position for the shelf 13 to be erected.

[0080] Of course, such as Figure 9 As shown, a limiting part 23 for preventing the supporting part 3 from continuing to flip away from the unfolded position to the side away from the storage position can also be provided on the fixing part 2. Specifically, when the supporting part 3 is in the second unfolded position, the outer wall of the supporting part 3 abuts against the limiting part 23.

[0081] It is worth noting that as the supporting part 3 flips from the first unfolding position to the second unfolding position, the triggering section will gradually move downward away from the extrusion surface 123 so as not to be squeezed by the extrusion surface 123.

[0082] In this embodiment, the supporting part 3 only enters the first unfolded position by the extrusion trigger section of the extrusion surface 123, instead of directly entering the second unfolded position. The significance of this is:

[0083] First, if the pressing surface 123 pushes the trigger section so that the supporting part 3 directly enters the second unfolded position, then in the second unfolded position, the pressing surface 123 will still be in contact with the trigger section, and will always apply downward pressure to the trigger section (mainly the pressure formed by the gravity of the second enclosure 12). The trigger section is continuously squeezed by the pressing surface 123, which can easily cause damage.

[0084] In this embodiment, through the above design, the supporting part 3 enters the second unfolded position from the first unfolded position by the gravity of the shelf 13, rather than by the compression of the extrusion surface 123. This ensures that in the second unfolded position, as... Figure 9 As shown, the extrusion surface 123 does not contact the trigger section, thus preventing the trigger section from being subjected to pressure from the extrusion surface 123, which helps protect the trigger section.

[0085] Secondly, since the supporting part 3 is closer to the storage position (or closer to the inner side of the first enclosure 11) in the first unfolded position than in the second unfolded position, such as Figure 8 and Figure 9As shown, in the first unfolded position, the distance D1 between the support part 3 and the edge of the fixing part 2 is less than the distance D2 between the support part 3 and the edge of the fixing part 2 in the second unfolded position. Thus, when the shelf 13 is not used, the support part 3 will only unfold in the first unfolded position, rather than in the second unfolded position. This reduces the distance by which the support part 3 protrudes from the inner surface of the first enclosure 11, thereby reducing the interference of the support part 3 with the internal space of the enclosure box.

[0086] Example 2

[0087] Combination Figures 1-11 As shown, in practical use, sometimes it is not necessary to use the shelf 13 to divide the enclosure box into layers, so the layered structure is unnecessary. In Embodiment 1, once the enclosure box is assembled, its supporting part 3 will naturally enter the unfolded position, thus occupying the internal space of the enclosure box. Therefore, in order to solve the problem that the supporting part 3 will not enter the unfolded position even when the enclosure box is assembled when the shelf 13 is not needed, this embodiment makes further improvements based on Embodiment 1, specifically:

[0088] The trigger segment is designed to be driven to extend and retract between a first position and a second position along the axial direction of the second guide 44.

[0089] like Figure 10 As shown, in the first position, the trigger segment is at least partially inserted into the slot 122.

[0090] like Figure 11 As shown, in the second position, the trigger segment is completely disengaged from the slot 122.

[0091] Thus, if the shelf 13 is not needed, before assembling each panel, the trigger segment is first adjusted to the second position. At this time, the trigger segment is disengaged from the slot 122, that is, it is offset from the pressing surface 123 in the horizontal direction. So when the second panel 12 is inserted into the first panel 11, since the trigger segment is offset from the pressing surface 123, even if it is inserted downwards, it will not be pressed, and thus the support part 3 will not be driven to flip to the unfolded position. In this way, the support part 3 will still be in the storage position.

[0092] Conversely, if the layered panels 13 are required, before assembling each panel, the trigger segment is adjusted to the first position so that it enters the slot 122 and is located below the extrusion surface 123. In this way, the support part 3 can automatically switch between the storage position and the unfolded position as described in Embodiment 1.

[0093] In some embodiments, the second guide portion 44 is a screw-type threaded telescopic structure, for example, as... Figure 6As shown, the second guide part 44 includes a screw 441 and a rigid screw sleeve 442. One end of the screw 441 is fixed to the slider 221. The second guide wheel 440 is rotatably connected to the screw 441. The screw sleeve 442 is threaded onto the screw 441. The screw sleeve 442 constitutes the aforementioned trigger section. Thus, by rotating the screw sleeve 442, the screw sleeve 442 can move axially along the screw 441 to achieve switching between the first position and the second position.

[0094] Example 3

[0095] Combination Figures 1-11 As shown, this embodiment provides a enclosure box, which includes a base 10 and a plurality of enclosure panels connected in sequence. The enclosure panels enclose the perimeter of the enclosure box, while the base 10 constitutes the bottom wall of the enclosure box. Adjacent enclosure panels are detachably connected, for example, as mentioned in Embodiment 1, adjacent enclosure panels are assembled or disassembled by a plug-in connection.

[0096] In addition, each panel and the base 10 are detachably connected. For example, the panels and the base 10 are fixed with screws, or the lower end of the panels and the base 10 are connected by a mortise and tenon structure, so that the entire panel box can be completely disassembled for storage.

[0097] In this embodiment, at least one of two adjacent panels has a layered structure as provided in Embodiment 1 or Embodiment 2. For example, in this embodiment, four panels are used, arranged in pairs opposite each other to form a rectangular frame structure. The layered structure is provided only on one pair of panels on opposite sides, and two layered structures are symmetrically arranged on both sides of the panel.

[0098] This embodiment also includes a shelf 13, which can be supported by a layered structure.

[0099] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
