Detailed Implementation

[0062] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0063] like Figure 1 and Figure 2 , combined Figure 3 , Figure 8 , Figure 10 and Figure 11 As shown, the folding storage box 200 with bottom plate linkage locking provided in this embodiment includes a box body 210 comprising a front panel 211, a rear panel 212, two foldable side panels 10, a bottom plate 20, and a cover plate 213. The bottom plate 20 is hinged to the bottom end of the rear panel 212, and the two foldable side panels 10 can be folded in half and unfolded. When the two foldable side panels 10 are unfolded, the box body 210 is in an unfolded state, as shown... Figure 1 As shown; when the two foldable side panels 10 are folded, the box body 210 is in a folded state, as... Figure 2 As shown.

[0064] In this embodiment, a bottom plate linkage locking mechanism 100 is provided between both foldable side plates 10 and bottom plate 20. In other embodiments, only one of the foldable side plates 10 and bottom plate 20 may be provided with a bottom plate linkage locking mechanism 100.

[0065] Specifically, such as Figures 3 to 9 ,as well as Figure 11This embodiment demonstrates the base plate linkage locking mechanism 100, which includes a first folding plate 11, a second folding plate 12, and a base plate 20. The first folding plate 11 and the second folding plate 12 are longitudinally hinged and can be folded relative to each other, forming the foldable side panel 10 of the foldable storage box 200 with base plate linkage locking in this embodiment. The base plate 20 is hinged to the bottom of the foldable storage box 200 with base plate linkage locking in this embodiment and the bottom end of the rear panel 212. Therefore, from a positional perspective, when the base plate 20 flips up and down, its side sweeps across the inner side of the foldable side panel 10 formed by the first folding plate 11 and the second folding plate 12.

[0066] like Figures 3 to 9 , Figure 11 As shown, the inner side of the first folding plate 11 is provided with a locking rod 30 that can move up and down, the inner side of the second folding plate 12 is provided with a locking groove 40, and the locking rod 30 is provided with a locking block 31 that matches the locking groove 40.

[0067] When the housing 210 is unfolded, the two foldable side panels 10 unfold, namely the first folding panel 11 and the second folding panel 12, and the bottom plate 20 flips downward, causing the locking rod 30 to move downward, and the locking block 31 inserts into the locking groove 40. Since the locking rod 30 is located on the first folding panel 11 and the locking groove 40 is located on the second folding panel 12, the two lock together to lock the first folding panel 11 and the second folding panel 12 in the unfolded state.

[0068] When the box 210 is folded, the cover plate 213 is removed, the bottom plate 20 is flipped upward, and the locking block 31 disengages from the locking groove 40 to unlock the first folding plate 11 and the second folding plate 12. The first folding plate 11 and the second folding plate 12 can be folded relative to each other, that is, the two foldable side plates 10 are folded relative to each other, the front panel 211 and the rear panel 212 are aligned, and the bottom plate 20 is stored inside the rear panel 212, and the entire box 210 is folded.

[0069] Therefore, the folding storage box with bottom plate linkage locking provided by this utility model has a bottom plate linkage locking mechanism between the foldable side panel and the bottom plate. When the box is unfolded, the bottom plate flips downward, causing the locking rod of the first folding plate to interlock with the locking groove of the second folding plate, automatically locking the foldable side panel in the unfolded state. When the box is folded, the bottom plate flips upward, the locking rod disengages from the locking groove, and the foldable side panel is automatically unlocked for further folding. This eliminates the need for manual locking and unlocking of the foldable side panel during the unfolding and folding process, improving the convenience of switching the box's state. Unfolding, locking, unlocking, and folding are all done in one step, optimizing the user experience.

[0070] like Figures 4 to 7As shown, the locking rod 30 includes a longitudinally arranged rod portion 32 and a locking portion 33 arranged laterally on the rod portion 32. A locking block 31 is disposed below the locking portion 33. A locking groove 40 is arranged laterally below the locking portion 33. The locking rod 30 disposed on the first folding plate 11 and the locking groove 40 disposed on the second folding plate 12 are locked together, which can lock the foldable side plate 10 in the unfolded state. Further, by arranging the locking portion 33 and the locking groove 40 laterally, and by matching the locking block 31 with the laterally arranged locking groove 40, the reliability and firmness of the locking can be enhanced.

[0071] like Figure 4 and Figure 6 As shown, a track 13 is longitudinally arranged on the inner side of the first folding plate 11, and the rod 32 is disposed in the track 13 and can move up and down within the track to provide longitudinal limiting and vertical guiding functions. The track 13 is formed by a groove 13a longitudinally formed on the inner side of the first folding plate 11, so that the locking rod 30 does not occupy the internal storage space of the box 210.

[0072] Furthermore, such as Figure 7 and Figure 8 As shown, the bottom end of the locking rod 30, i.e., the rod portion 32, is provided with an inwardly extending pushing portion 34. The base plate 20 is flipped downward, and the side of the base plate 20 pushes the pushing portion 34 downward to drive the locking rod 30 to move downward. Preferably, the pushing portion 34 is in the shape of an upward hook to hook onto the side of the base plate 20.

[0073] like Figure 6 and Figure 9 As shown, a spring 14 is provided between the rod portion 32 of the locking rod 30 and the first folding plate 11. When the bottom plate 20 is flipped upward, the elastic force of the spring 14 pushes the locking rod 30 upward, so that the locking block 31 automatically disengages from the locking groove 40.

[0074] It should be noted that in this embodiment, the first folding plate 11 of both foldable side panels 10 is the folding plate connected to the front panel 211, that is, the locking rods 30 on both sides are located on the inner side of the folding plate connected to the front panel 211, and the two are mirror-symmetrical. Of course, in other embodiments, the first folding plate 11 may also refer to the folding plate connected to the rear panel 212, and the locking rods 30 may be located on the inner side of the folding plate connected to the rear panel 212. Furthermore, when both foldable side panels 10 are provided with a bottom plate linkage locking mechanism 100, the two may not be mirror-symmetrical.

[0075] like Figure 10As shown, the bottom of the front panel 211 is provided with an elastic stop member 50. The bottom plate 20 extends downward past the elastic stop member 50 to hold the bottom plate 20 at the bottom of the housing 210. The bottom plate 20 extends upward past the elastic stop member 50 to flip the bottom plate 20 upward. The elastic stop member 50 includes an inwardly extending stop portion 51 and an upwardly extending guide portion 52. The guide portion 52 is inclined outward from bottom to top. When the bottom plate 20 flips downward, it contacts and presses against the guide portion 52, causing the guide portion 52 to produce a certain degree of elastic deformation, guiding the bottom plate 20 downward past the elastic stop member 50. The stop portion 51 holds the bottom plate 20 at the bottom of the housing 210.

[0076] Furthermore, such as Figure 10 and Figure 11 As shown, a mesh plate 214 is provided on the inner side of the front panel 211, forming a receiving space 215 between the mesh plate 214 and the front panel 211 for storing the cover plate 213. After the cover plate 213 is removed, it can be inserted into the receiving space 215 for storage. An elastic stop member 50 is provided at the bottom of the mesh plate 214. It can be directly provided at the bottom of the mesh plate 214 or at the bottom of the front panel 211, and protrudes from a notch at the bottom of the mesh plate 214.

[0077] In other embodiments, the mesh panel 214 may be omitted, and the cover 213 may be externally mounted or stored by a stop block on the inside of the front panel 211. Alternatively, the cover 213 may be omitted entirely, in which case the elastic stopper 50 may be located at the bottom of the front panel 211. Furthermore, other limiting structures may be provided at the bottom of the front panel 211 or the mesh panel 214 to hold the bottom plate 20 at the bottom of the housing 210. For example, a snap-fit ​​structure may be provided between the bottom plate 20 and the bottom of the front panel 211 or the mesh panel 214.

[0078] In this embodiment, there are two elastic abutment members 50, which are respectively arranged on both sides of the bottom of the mesh plate 214. In other embodiments, the number and position of the elastic abutment members 50 can be adjusted according to the size, weight, etc. of the box 210, for example, increasing to three.

[0079] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0080] The foregoing has described the base plate linkage locking mechanism and the folding storage box with base plate linkage locking provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand this utility model and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
