Description

Technical Field

[0001] This application relates to the technical field of folding boxes, and in particular to a folding storage box. Background Technology

[0002] When people travel outdoors or shop, they often need storage boxes as containers to store their items. Currently, the continuous improvement of storage box technology focuses on achieving rapid folding and unfolding while minimizing the folded size. The most mature folding mechanisms on the market are primarily hinged. Taking the folding box with patent authorization announcement number CN217937439U as an example, it has four side panels: two folding side panels and two fixed side panels. The folding side panels include two hinged folding parts, which fold inwards to fit against the fixed side panels. Before folding the box, the bottom and cover plates need to be rotated to ensure they are in contact with the side panels before the folding side panels can be folded inwards.

[0003] Similarly, another common folding storage method involves a lid that detachably closes to the top of the case. To fold the case, simply remove the lid, rotate the bottom panel, and then rotate the side panels to fold it. For rotating lids, a pivot point is needed on the case as the center of rotation. However, this method is less convenient to install than a directly closed lid, and when multiple cases are stacked vertically, the upper case directly presses against the lower cases, potentially damaging the pivot point of the lower cases (the cases are usually made of plastic, which has limited strength). Therefore, folding cases with directly closed lids are still widely used in the market.

[0004] For folding boxes with directly closing lids, the inventors discovered the following drawbacks: the lids are easily lost after being removed, especially when the height of the items loaded inside the folding box exceeds the height of the internal cavity, making it impossible for the lids to close properly. In this case, the lids are more likely to be lost. Summary of the Invention

[0005] In order to prevent the lid of the folding storage box from being lost, this application provides a folding storage box.

[0006] This application provides a folding storage box, which adopts the following technical solution:

[0007] A folding storage box includes two parallel and spaced fixed side plates, two parallel and opposite folding side plates, a bottom plate rotatably disposed at the bottom of the fixed side plates, and a cover plate. The two folding side plates, the two fixed side plates, and the bottom plate form a receiving cavity. The cover plate covers the opening of the receiving cavity. The bottom of the outer side of the fixed side plate is provided with an abutment portion. Two sets of limiting members are symmetrically arranged on the outer side of the fixed side plate. The limiting members include a first limiting portion for abutting against the side wall of the cover plate and a second limiting portion for abutting against the end face of the cover plate. When the cover plate is in the storage state, the top of the abutment portion abuts against the cover plate, and the two sets of limiting members clamp the two sides of the cover plate.

[0008] By adopting the above technical solution, when storing the folding storage box, the cover is removed and inserted into the gap between the limiting member and the fixed side plate, while the abutting part abuts against the bottom of the cover. By temporarily placing the cover on the fixed side plate, the cover is less likely to be lost when the folding box is stored.

[0009] Optionally, the abutting part is provided with a positioning groove, and the cover plate is provided with a positioning block for embedding into the positioning groove.

[0010] By adopting the above technical solution, the cover plate is further limited by embedding the positioning block into the positioning groove, and the position of the cover plate can be more stable.

[0011] Optionally, the limiting member is movably disposed on the fixed side plate, and the fixed side plate has a sliding groove for the limiting member to slide into. Sliding openings are provided on the groove walls on both sides of the sliding groove, and sliding blocks that slide into the sliding openings are provided on both sides of the first limiting part.

[0012] By adopting the above technical solution, when the limiting component does not need to limit the cover plate, the limiting component can be pushed into the sliding groove, thereby hiding the limiting component and ensuring the flatness of the fixed cover plate surface.

[0013] Optionally, the limiting member is movably disposed on the fixed side plate, and the fixed side plate has a sliding groove for the limiting member to slide into. Sliding openings are provided on the groove walls on both sides of the sliding groove, and sliding blocks that slide into the sliding openings are provided on both sides of the first limiting part.

[0014] By adopting the above technical solution, the sliding movement of the limiting component is limited by the sliding block, making it difficult for the limiting component to fall out of the sliding groove.

[0015] Optionally, the sliding block includes a triangular guide portion and a square sliding portion.

[0016] By adopting the above technical solution and setting a guide part, it is convenient to forcefully insert the limiting part into the slot of the sliding groove with an interference fit.

[0017] Optionally, the second limiting part is provided with a snap-fit ​​protrusion, and the groove wall of the sliding groove is provided with a snap-fit ​​groove for the snap-fit ​​protrusion to be inserted.

[0018] By adopting the above technical solution, when the limiting component slides into the sliding groove, the snap-fit ​​protrusion is also embedded into the snap-fit ​​groove, thereby making the position of the limiting component more stable when it is hidden in the sliding groove.

[0019] Optionally, the first limiting part is provided with a snap groove for inserting a finger, and the fixed side plate is provided with a clearance opening that communicates with the sliding groove.

[0020] By adopting the above technical solution, it is convenient to manually slide the limiting component.

[0021] Optionally, the second limiting part is provided with a mounting groove, a spring-loaded spring is provided in the mounting groove, a through hole is provided at the bottom of the mounting groove for the spring-loaded spring to pass through, and a rotating component is rotatably provided on the fixed side plate for abutting against the bottom of the mounting groove.

[0022] By adopting the above technical solution, when the rotating component rotates to a position where it does not abut against the limiting member, the spring-loaded spring will spring the limiting member open, at which point the cover plate can be inserted between the limiting member and the fixed side plate.

[0023] Optionally, the rotating assembly includes a rotating screw threadedly connected to the fixed side plate and an abutment rod rotatably sleeved on the rotating screw, the abutment rod being used to rotatably abut against the bottom of the mounting groove.

[0024] By adopting the above technical solution and setting a rotating screw, the abutment rod can be easily rotatably installed on the fixed side plate.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When the folding storage box is folded, the lid can be installed on the fixed side panel to prevent the lid from being lost;

[0027] 2. By sliding the limiting component within the sliding groove, the limiting component can be hidden, ensuring the flatness of the fixed side plate surface;

[0028] 3. By setting a spring-loaded spring, when the rotating component does not limit the limit component, the limit component can automatically spring open, at which point the cover plate can be directly inserted into the outside of the fixed side plate. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0038] This application discloses a folding storage box.

[0039] Reference Figure 1 , Figure 2 as well as Figure 4The folding storage box includes two parallel fixed side plates 1, two parallel opposing folding side plates 2, a bottom plate 5, and a cover plate 3. The bottom plate 5 is hinged to the bottom of one of the fixed side plates 1, and the other fixed side plate 1 has an abutment platform 11 for abutting against the bottom of the bottom plate 5. When the folding storage box is in the unfolded state, the bottom plate 5 rests on the abutment platform 11, and the bottom plate 5, the two fixed side plates 1, and the two folding side plates 2 together form a cavity 6 for placing items, with the cover plate 3 covering the opening of the cavity 6. The two sides of the folding side plates 2 are hinged to the two fixed side plates 1 respectively; the folding side plates 2 include two symmetrically arranged folding parts 21. When the folding storage box needs to be folded, the bottom plate 5 is rotated so that it fits against the inner wall of one of the fixed side plates 1, and then the cover plate 3 is removed; then the two folding side plates 2 are folded inward so that the two folding parts 21 move closer together, and the two fixed side plates 1 also move closer together.

[0040] Reference Figure 1 and Figure 2 Both the fixed side plate 1 and the folding side plate 2 have support platforms 12 on their upper inner walls for abutting against the bottom of the cover plate 3. The cover plate 3 has positioning blocks 31 and positioning protrusions 32, and the fixed side plate 1 has positioning slots 13 for the positioning blocks 31 and positioning protrusions 32 to be inserted. By snapping the cover plate 3 onto the top of the folding box, the cover plate 3 is less likely to fall off. Simultaneously, the fixed side plate 1 has a latching opening 14 to facilitate snapping the cover plate 3 off.

[0041] Reference Figure 3 and Figure 4 The bottom of the outer side of the fixed side plate 1 is integrally connected with an abutment portion 15, and two sets of limiting members 4 are symmetrically arranged on the outer side of the fixed side plate 1. Each set of limiting members 4 can consist of one or more; in this embodiment, only one limiting member 4 is provided in each set. The limiting member 4 includes a first limiting portion 41 for abutting against the side wall 33 of the cover plate and a second limiting portion 42 for abutting against the end face 34 of the cover plate. When the cover plate 3 is in the retracted state, the top of the abutment portion 15 abuts against the cover plate 3, thereby vertically limiting the cover plate 3. The two limiting members 4 clamp the cover plate 3 to limit its movement in the front-back and left-right directions. The abutment portion 15 has a positioning groove 151 for the positioning block 31 to be inserted into.

[0042] Reference Figure 5 and Figure 6The limiting member 4 is movably mounted on the fixed side plate 1. The fixed side plate 1 has a sliding groove 16 for the limiting member 4 to slide into. Sliding openings 161 are formed on the groove walls on both sides of the sliding groove 16. Sliding blocks 411 are integrally provided on both sides of the first limiting part 41, which slide into the sliding openings 161. By providing sliding blocks 411, the limiting member 4 is not easily dislodged from the sliding groove 16. The sliding blocks 411 include a triangular guide part 4111 and a square sliding part 4112. When the limiting member 4 is installed, the sliding part 4112 can slide into the sliding opening 161 through the guiding action of the guide part 4111. During the process of locking the sliding part 4112 into the sliding opening 161, the first limiting part 41 undergoes a certain degree of deformation (the limiting member 4 itself is made of plastic material, which can deform to a certain extent).

[0043] Reference Figure 5 and Figure 6 The second limiting part 42 is provided with a snap-fit ​​protrusion 412, and the groove wall of the sliding groove 16 is provided with a snap-fit ​​groove 162 for the snap-fit ​​protrusion 412 to be inserted. When the limiting member 4 is slidably inserted into the sliding groove 16, the limiting member 4 can be stably inserted into the sliding groove 16 through the snap-fit ​​protrusion 412.

[0044] Reference Figure 5 and Figure 6 The first limiting part 41 has a latching groove 43 for inserting a finger, which facilitates the sliding of the limiting member 4 out of the sliding groove 16, allowing the limiting member 4 to limit the position of the cover plate 3. At this time, the snap-fit ​​protrusion 412 retracts from the snap-fit ​​groove 162. Simultaneously, by providing the latching groove 43, the side walls of the limiting member 4 are more easily deformed during the interference fit installation of the limiting member 4 in the sliding groove 16, making it easier for the sliding block 411 to embed into the sliding opening 161. The fixed side plate 1 has a clearance opening 18 communicating with the sliding groove 16 to facilitate inserting a finger into the latching groove 43.

[0045] Reference Figure 7In another embodiment, the second limiting part 42 is provided with a mounting groove 44, and two spring-loaded springs 45 are provided in the mounting groove 44. The bottom of the mounting groove 44 is provided with a through hole 46 for the spring-loaded springs 45 to slide through. A rotating assembly 17 is rotatably provided on the fixed side plate 1 for abutting against the bottom of the mounting groove 44. When the rotating assembly 17 is rotated so that it is not abutting against the bottom of the mounting groove 44, the limiting member 4 is released under the elastic force of the spring-loaded springs 45. At this time, the cover plate 3 can be inserted between the second limiting part 42 and the fixed side plate 1. After the cover plate 3 is removed from the fixed side plate 1, the limiting member 4 is completely slid into the sliding groove 16, and then the rotating assembly 17 is rotated so that it abuts against the bottom of the mounting groove 44, thereby locking the limiting member 4 again.

[0046] The rotating assembly 17 includes a rotating screw 171 threadedly connected to the fixed side plate 1 and an abutment rod 172 rotatably sleeved on the rotating screw 171. The abutment rod 172 is limited by the nut portion of the rotating screw 171, thereby allowing the abutment rod 172 to be rotatably mounted on the fixed side plate 1.

[0047] The implementation principle of a folding storage box according to an embodiment of this application is as follows: When storing the folding storage box, first rotate the bottom plate 5 so that the bottom plate 5 fits against the fixed side plate 1, and remove the cover plate 3; at the same time, fold the two folding side plates 2 inward, and bring the two fixed side plates 1 closer together. Then, insert the cover plate 3 into the outside of the fixed side plate 1, and limit the cover plate 3 through the abutment part 15 and the limiting member 4.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
