Technical Field

[0001] The utility model belongs to the technical field of storage boxes, and particularly relates to a foldable storage device. Background Art

[0002] Storage devices are common devices in daily life used to assist users in storing items, such as storage boxes or drawers, which are usually composed of a bottom wall and four side walls extending from the bottom wall, so that the bottom wall and the side walls form a storage space for users to store items.

[0003] In order to facilitate transportation and save space when not in use, storage devices are generally set to be foldable. However, existing foldable storage devices are generally designed to be detachable and reassembled. The detachable state is convenient for transportation, and the assembled state is used for storage. When the storage is needed, the user needs to assemble and fix it first, and then disassemble it again after use, which is very inconvenient. Utility Model Content

[0004] The purpose of the present invention is to provide a foldable storage device with a simple structure and reasonable design in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] As a further optimization solution of the present invention, handles are fixedly connected to the outer side walls of the two hard side panels, and universal wheels are installed at both ends of the bottom of the two hard side panels.

[0008] As a further optimization solution of the present invention, the rotating shaft is in a round rod-shaped structure, a plurality of annular grooves are provided on the rotating shaft, and the first connecting arm and the second connecting arm are both rotatably connected to the rotating shaft through the annular grooves.

[0009] As a further optimization scheme of the present invention, the connecting part includes two ear plates fixedly installed on the inner wall of the hard side panel, a connecting shaft is provided between the two ear plates, the two ends of the connecting shaft are respectively fixed to the two ear plates, and the first connecting arm and the second connecting arm are rotatably connected to the connecting shafts installed on the inner walls of the two hard side panels at one end away from the rotating shaft.

[0010] As a further optimization solution of the present invention, the bottom plate is made of a hard material. When the bottom plate is rotated downward to a horizontal state, the peripheral side of the bottom plate fits with the hard side plate and the inner wall of the flexible side plate.

[0011] As a further optimization solution of the present invention, an upper hook is fixedly installed on the inner wall of the top end of the hard side panel connected to the bottom panel, and the distance between the upper hook and the bottom end of the bottom panel is equal to the length of the bottom panel.

[0012] The beneficial effect of the present invention is that when storing items, the rotating shaft is pressed downward to drive the first connecting arm and the second connecting arm to rotate and push the hard side panels on both sides to unfold, and the flexible side panels are pulled tight to form the side edges of the storage device. Then the user lays the bottom plate above the first connecting arm and the second connecting arm to form a bottom wall, and the items can be stored. When not in use, the rotating shaft is pulled upward to drive the first connecting arm and the second connecting arm to retract, so that the entire device can be folded.

[0018] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example

[0020] like Figure 1 - Figure 4 As shown, it includes two symmetrically arranged hard side panels 1, and flexible side panels 2 are fixedly connected between the two ends of the two hard side panels 1. The hard side panels 1 and the flexible side panels 2 together enclose the side walls of the storage device. Handles 3 are fixedly connected to the outer walls of the two hard side panels 1. Universal wheels 4 are installed at both ends of the bottom of the two hard side panels 1. The handles 3 are provided to facilitate users to carry the entire storage device through the handles 3. The universal wheels 4 are provided so that users can push the entire structure on a flat road to drive the universal wheels 4 to roll along the road, making it easier for users to carry stored items.

[0021] A rotating shaft 5 is provided between the two rigid side panels 1. The rotating shaft 5 is in the shape of a round rod and has a plurality of annular grooves 6 formed thereon. A set of first connecting arms 7 is mounted on one side of the rotating shaft 5, and a set of second connecting arms 8 is mounted on the other side of the rotating shaft 5. The first connecting arms 7 and the second connecting arms 8 are both rotatably connected to the rotating shaft 5 through the annular grooves 6, and the first connecting arms 7 and the second connecting arms 8 are staggered. The annular grooves 6 are provided to limit the first connecting arms 7 and the second connecting arms 8, so as to prevent the first connecting arms 7 and the second connecting arms 8 from sliding along the length direction of the rotating shaft 5 as much as possible.

[0022] The free ends of the first connecting arm 7 and the second connecting arm 8 are rotatably connected to the inner walls of the bottom ends of the two rigid side panels 1 through connecting members. The connecting members include two ear plates 9 fixedly mounted on the inner walls of the rigid side panels 1. A connecting shaft 10 is provided between the two ear plates 9. Both ends of the connecting shaft 10 are respectively fixed to the two ear plates 9. The ends of the first connecting arm 7 and the second connecting arm 8 away from the rotating shaft 5 are rotatably connected to the connecting shafts 10 mounted on the inner walls of the two rigid side panels 1.

[0023] A limit buckle 11 is fixedly connected to the middle section of the flexible side plate 2 for limiting the end of the rotating shaft 5. When the first connecting arm 7 and the second connecting arm 8 rotate to a parallel state, the end of the rotating shaft 5 is just stuck in the limit buckle 11, and the limit buckle 11 prevents the rotating shaft 5 from further turning downward;

[0024] A bottom plate 12 is provided on the inner side wall of one of the hard side panels 1, one end of which is rotatably connected to the hard side panel 1. The bottom plate 12 is made of a hard material. When the bottom plate 12 is rotated downward to a horizontal state, the circumference of the bottom plate 12 is in contact with the inner walls of the hard side panel 1 and the flexible side panel 2, and is used to be laid above the first connecting arm 7 and the second connecting arm 8, serving as the bottom wall of the entire storage device.

[0025] A plurality of hanging rings 13 are fixedly connected to the periphery of the bottom plate 12, and lower hooks 15 arranged in correspondence with the hanging rings 13 are fixedly connected to the inner walls of the flexible side panels 2 and the hard side panels 1 above the connecting piece. An upper hook 14 is fixedly installed on the inner wall of the top end of the hard side panel 1 connected to the bottom plate 12, and the distance between the upper hook 14 and the bottom end of the bottom plate 12 is equal to the length of the bottom plate 12. When the bottom plate 12 is rotated to a horizontal state, the periphery of the bottom plate 12 can be connected and fixed to the inner walls of the bottom ends of the hard side panels 1 and the flexible side panels 2 by means of the hanging rings 13 and the lower hooks 15, which is convenient for users to use.

[0026] It should be noted that when using this foldable storage device, the rotating shaft 5 is pressed downward. Since the two sides of the rotating shaft 5 are rotatably connected to the hard side panels 1 on both sides through the first connecting arm 7 and the second connecting arm 8, the rotating shaft 5 can drive the first connecting arm 7 and the second connecting arm 8 to rotate during the downward movement, thereby stretching the hard side panels 1 and tightening the flexible side panels 2. When the first connecting arm 7 and the second connecting arm 8 are rotated to be parallel to each other, the end of the rotating shaft 5 is just embedded in the limiting buckle 11 from the open end of the limiting buckle 11, and the limiting buckle 11 is used to support the rotating shaft 5 to prevent the rotating shaft 5 from continuing to flip downward to form an unfolded storage device. Then the user rotates the bottom plate 12 downward along the connection between the bottom plate 12 and the hard side panel 1, and spreads the hard material bottom plate 12 flat on the first connecting arm The arm 7 is above the second connecting arm 8, and the hanging ring 13 set on the side of the bottom plate 12 is hung on the lower hook 15 fixedly installed on the inner wall of the bottom end of the hard side plate 1 and the flexible side plate 2 to form the bottom wall of the overall storage device, and the storage device can be used to store items. When there is no need to store items, the user removes the hanging ring 13 from the lower hook 15, rotates the bottom plate 12 to a vertical state, and then hangs the hanging ring 13 at one end of the bottom plate 12 away from the hard side plate 1 on the upper hook 14, and then pulls the rotating shaft 5 upward to disengage the end of the rotating shaft 5 from the open end of the limit buckle 11. At this time, the rotating shaft 5 drives the first connecting arm 7 and the second connecting arm 8 to retract, thereby realizing the folding of the overall storage device. There is no need to disassemble and assemble the storage device, which is convenient for users to use.

[0027] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
