TECHNICAL FIELD

The utility model relates to the technical field of storage boxes, and in particular to a foldable storage box.

BACKGROUND

Storage boxes are containers used to store, organize, and protect items. They usually have a closed structure, which can place items in an orderly manner, and the needed items can be easily taken out. The design and function of the storage box vary according to the purpose, and can be used in homes, offices, schools, factories, etc. Storage boxes can also be distinguished based on their shape, material and characteristics. Some common storage box types include plastic boxes, paper boxes, fabric boxes, metal boxes, etc. They can have different sizes, colors and organization methods to accommodate different types of items and space needs;

Typically, foldable storage boxes are not strong enough to effectively hold items therein and are prone to deformation, which affects the normal uses of the storage boxes. For this reason, we propose a foldable storage box to solve the above problems.

DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all implementations. example.

Referring to FIGS. 1-13, a foldable storage box includes a box frame 1. The box frame 1 is surrounded by a bottom wall panel 2 clamped at the bottom of the box frame 1 to form a storage space. The side walls of the box frame 1 are provided with multiple frame grooves or hinges 3 for folding the box frame 1. The bottom of the box frame 1 is integrally formed with several supporting straps 4. The supporting straps 4 are arranged on the outside of the bottom wall panel 2, and the supporting straps 4 are engaged with the bottom wall panel 2. By arranging the supporting strap 4 integrated with the box frame 1, the strength and stability of the storage box are enhanced. Even if it is made into a larger storage box, the bottom wall panel 2 can still be firmly installed and will not fall off or deform during use, causing the storage box to be unusable. A folding groove or hinge 5 is provided in the middle of the support belt 4, a plurality of first grooves 6 are provided on both sides of the folding groove or hinge 5, and a plurality of second grooves 7 are provided on the back of the folding groove 5. A third folding groove or hinge 8 is provided at the connection between the support belt 4 and the box frame 1, through the arrangement of the folding groove or hinge 5 and the third folding groove or hinge 8.

The support strap 4 is conveniently folded at the folding groove or hinge 5 and the third folding groove or hinge 8. By setting the first grooves 6 and the second grooves 7 on opposite sides, the strength of the support strap 4 is enhanced and the weight of the support strap 4 is reduced, so that the strength of the storage box is increased at the same time, so as not to be too bulky. A plurality of intersecting bottom reinforcement strips 9 are provided on the bottom surface of the bottom wall panel 2. The bottom reinforcement strips 9 are provided with strip grooves 10 that match the support straps 4. Through the strip grooves 10 and the support strips 4, cooperation makes the installation of the support strap 4 more secure and will not cause the bottom wall panel 2 to fall off or deform during use, causing the storage box to become unusable.

Foot assemblies 11 are provided at the four corners below the bottom wall panel 2. The foot components 11 include a mounting base 12 and a sliding device 23 provided at the bottom of the mounting base 12. A mounting cavity 13 is provided at the four corners at the bottom of the bottom wall panel 2, symmetrical connection holes 14 are provided at the four corners of the bottom of the box frame 1, fixing columns 15 matching the connection holes 14 are symmetrically provided above the mounting base 12 and the mounting cavity 13 is provided at the upper end side of the mounting base 12. The positioning posts 16 matched with the side walls are installed through the connection holes 14 and the fixing posts 15. The installation cavity 13 is installed with the positioning posts 16 so that the foot components 11 are firmly installed at the four corners below the bottom wall plate 2. The sliding device 23 allows the storage box to slide freely on a floor, making it more convenient to use.

The bottom edge of the box frame 1 is provided with multiple limit plates 17, and the bottom of the bottom wall panel 2 is provided with multiple bottom slots 18 that match the limit plates 17, a plurality of limit buckles 19 are provided above the limit plates 17, the limit buckles 19 are arranged on the top of the bottom wall panel 2. A plurality of positioning buckles 20 are provided at the bottom of the bottom wall plate 2, and a plurality of positioning buckle slots 21 are provided at the bottom of the box frame 1. The positioning buckle slots 21 matching the positioning buckles 20 are installed by matching the limit plates 17 with the bottom slots 18, and then is set on the top of the bottom wall plate 2 through the limit buckles 19. The bottom slots 18 are limited above the limit plate 17 and are installed with the positioning buckles 20 and the positioning buckle slots 21 so that the bottom wall plate 2 is firmly connected to the bottom of the box frame 1. The box frame 1 is provided with a jagged or corrugated wall 22 to increase the strength of the box frame 1 and make the storage box more beautiful.

In the utility model, when in use, the bottom wall plate 2 is clamped at the bottom of the box frame 1 to form a storage space, and the limit plates 17 are matched with the bottom slots 18 for installation, and then the limit buckles 19 are used to set the storage space. On the top of the bottom wall panel 2, the bottom slots 18 are limited or positioned above the limit plate 17, and the positioning buckles 20 are installed into the positioning slots 21, so that the bottom wall panel 2 is firmly clamped on the bottom of the box frame 1, to keep the box frame 1 in an open state, and at the same time, the several support straps 4 are integrally formed at the bottom of the box frame 1. Through the support straps 4 arranged on the outside of the bottom wall panel 2 and snap-fitted with the bottom wall panel 2, the storage box has enhanced strength. Even if it is made into a larger storage box, the bottom wall panel 2 can still be firmly installed and will not fall off or deform during use, rendering the storage box unusable.

The foot assemblies 11 with sliding devices 23 can also be installed at the four corners below the bottom wall plate 2 and installed in conjunction with the fixing posts 15 through the connecting holes 14 and the installation cavity 13 in conjunction with the positioning posts 16 so that the foot assemblies 11 can be firmly installed on the four corners below the bottom wall panel 2, the sliding devices 23 allow the storage box to slide freely, making it more convenient to use.

When the device is not in use, the storage box may be folded. For folding, the bottom wall panel 2 is removed, the box frame 1 is folded inward or outward along the frame groove hinge 3, and the support strap(s) 4 is/are folded inward or outward along the folding groove or hinge 5 and the third groove or hinge 8. The box frame 1 is greatly reduced in size, saving storage space.
