[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The present invention is further described in detail below with reference to the embodiments.

[0027] A specific embodiment of a foldable storage box provided by the utility model:

[0028] like Figure 1 and Figure 2As shown, the foldable storage box includes a box bottom plate 1, a box back plate 2, a box door frame 3 and two box side plates 4. The box bottom plate 1 is a rectangular structure, and the front-to-back direction of the box bottom plate 1 is the width of the box bottom plate 1, and the left-right direction of the box bottom plate 1 is the length of the box bottom plate 1. The lower edges of the two box side plates 4 are respectively mounted on the left and right sides of the box bottom plate 1 by hinged means, and the lower edge of the box back plate 2 is mounted on the back of the box bottom plate 1 by hinged means. The box door frame 3 is an inverted U-shaped structure, and the lower ends of the box door frame 3 are respectively mounted on the front of the box bottom plate 1 by hinged means; the hinge between the box back plate 2 and the box bottom plate 1 The height of the hinge point is higher than that of the hinge point between the door frame 3 and the bottom plate 1, and the height of the hinge point between the door frame 3 and the bottom plate 1 is higher than that of the hinge point between the side panels 4 and the bottom plate 1; the sum of the heights of the two side panels 4 is less than or equal to the length of the bottom plate 1; due to the above hinge method and height restrictions, the rear panel 2, side panels 4 and door frame 3 on the outer periphery of the bottom plate 1 can be folded. When folding, first fold the two side panels 4 in half and close to the bottom plate 1, then fold the door frame 3 and place it on the upper surface of the side panels 4, and finally fold the rear panel 2 and place it on the upper surface of the door frame 3.

[0029] In this embodiment, the box rear plate 2, the box door frame 3 and the box side plate 4 are all mounted on the periphery of the box bottom plate 1 in a hinged manner. Preferably, as shown in FIG. Figure 3 As shown, the hinge method is a T-shaped shaft 5 and a T-shaped rotating groove 6, and a ridge 7 is provided at the bottom of the T-shaped rotating groove 6. For example, the hinge method between the box side panel 4 and the box bottom panel 1 is as follows: the T-shaped shaft 5 is connected to the bottom of the box side panel 4, and the T-shaped rotating groove 6 is provided on the box bottom panel 1. The T-shaped shaft 5 is located in the T-shaped rotating groove 6, and the T-shaped shaft 5 can rotate around the T-shaped rotating groove 6. The ridge 7 can limit the T-shaped shaft 5 from escaping the T-shaped rotating groove 6, and the box side panel 4 can be hinged to the box bottom panel 1. The way in which the box rear panel 2 and the box door frame 3 are hinged to the box bottom panel 1 is the same as described above and will not be repeated here.

[0030] like Figure 4 and Figure 5 As shown, hooks 8 are connected to both sides of the upper part of each box side panel 4, first side bars 9 are connected to both sides of the left and right sides of the box rear panel 2, and second side bars 10 are connected to both sides of the left and right sides of the box door frame 3. The box rear panel 2 and the first side bars 9 are perpendicular to each other, and the box door frame 3 and the second side bars 10 are perpendicular to each other. Eyelet holes 11 are provided on the upper parts of the first side bars 9 and the second side bars 10.

[0031] The upper sides of the box side panels 4 are respectively engaged with the eyelet holes 11 of the first side stop 9 and the eyelet holes 11 of the second side stop 10 through hooks 8. The hooks 8 are buckled into the eyelet holes 11 of the first side stop 9 to form a rearward limit for the box rear panel 2, and the hooks 8 are buckled into the eyelet holes 11 of the second side stop 10 to form a forward limit for the box door frame 3.

[0032] The first side stop 9 on the left side of the box rear panel 2 and the second side stop 10 on the left side of the box door frame 3 form a limit to the left side panel 4 on the left side, and the first side stop 9 on the right side of the box rear panel 2 and the second side stop 10 on the right side of the box door frame 3 form a limit to the right side panel 4 on the right side;

[0033] In addition, a door 12 is installed in the door frame 3 .

[0034] When the foldable storage box of this embodiment is not in use, the side panels 4, the door frame 3 and the rear panel 2 can be folded in sequence through the hinge points set at different heights, thereby reducing the space occupied by the storage box. In addition, when the foldable storage box needs to be used, the rear panel 2 and the door frame 3 are opened in sequence, and the two side panels 4 are flipped over so that one hook 8 on the side panel 4 is buckled into the eyelet hole 11 of the first side stopper 9, and the other hook 8 is buckled into the eyelet hole 11 of the second side stopper 10. The buckle cooperation of the hook 8 and the eyelet hole 11 can form a limit for the door frame 3 and the rear panel 2 to prevent the door frame 3 from shifting forward and the rear panel 2 from shifting backward. The first side stopper 9 and the second side stopper 10 can limit the side panels 4 of the box. Finally, the rear panel 2, the door frame 3 and the two side panels 4 form a stable structure through the above-mentioned limit. Even if too many items are put into the storage box, the boxes will not be stretched open.

[0035] In addition, in order to facilitate the carrying of the storage box, buckle grooves 13 can be provided on the box door 12 and the two box side panels 4. A box cover 14 can also be provided, and the box cover 14 buckles and covers the top of the box back plate 2, the box door frame 3 and the two box side panels 4.

[0036] As another embodiment of the present invention, the door 12 is installed as follows: Figure 6-8 As shown, oblong holes 15 are provided on the opposite inner sides of both ends of the lower part of the door frame 3, and short shafts 16 are fixed on both sides of the lower end of the door 12. The two short shafts 16 are respectively located in the oblong holes 15, and the short shafts 16 can move up and down in the oblong holes 15. The door 12 is hingedly installed in the door frame 3 through the cooperation of the two short shafts 16 and the two oblong holes 15. The height of the door 12 is less than the height of the inner side of the door frame 3;

[0037] Both sides of the door frame 3 are fixed with limited narrow edges 17, which limit the door 12 in the rear direction.

[0038] A triangular guide lock 18 (such as Figure 7 As shown), both sides of the upper part of the door 12 are provided with L-shaped slots 19 (as shown Figure 8 As shown), the two L-shaped slots 19 are respectively matched with the two triangular guide locks 18 to form a snap structure, and the triangular guide locks 18 limit the L-shaped slots 19 on the door 12 in the forward direction.

[0039] When the door 12 needs to be opened, the door 12 is pulled upward, and the door 12 moves upward in the door frame 3. The L-shaped slot 19 on the door 12 moves upward relative to the triangular guide lock buckle 18, and the triangular guide lock buckle 18 no longer restricts the L-shaped slot 19, and the door 12 can be opened outward. When the door 12 is closed, the L-shaped slot 19 gradually approaches the triangular guide lock buckle 18. The L-shaped slot 19 first contacts the inclined surface of the triangular guide lock buckle 18, and the inclined surface of the triangular guide lock buckle 18 plays a guiding role, causing the L-shaped slot 19 to slide upward. After passing the highest point of the triangular guide lock buckle 18, the triangular guide lock buckle 18 smoothly slides into the L-shaped slot 19, and the door 12 is closed.
