Description

Technical Field

[0001] This utility model relates to the field of shelving technology, and in particular to a double-folding shelving unit. Background Technology

[0002] Most wall-mounted shelves on the market are fixed structures, which take up a lot of space and are not easy to store or move.

[0003] While some foldable shelves can reduce space usage, their folding methods are often relatively simple, making it impossible to completely separate the shelves for independent use. Furthermore, the overall thickness or volume remains large after folding, making them inconvenient for storage and transportation. Utility Model Content

[0004] In view of the above problems, the technical problem to be solved by this utility model is to provide a double-folding storage rack.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a double-folding shelf, including a first frame and a second frame, the first frame and the second frame are hinged together, the first frame and the second frame are rotated to change the placement angle between them, the first frame and the second frame are each provided with a component for adsorbing / adhering to the wall, characterized in that the first frame is provided with a plug shaft / receiving shaft hole, the second frame is provided with a corresponding receiving shaft hole / plug shaft, the first frame and the second frame are both provided with a surrounding edge; the volume of the first frame is larger than the volume of the second frame, the first frame and the second frame can be separated independently; in the folded state, the separated second frame is stacked inside the first frame, and the height of the surrounding edge of the second frame is basically the same as that of the surrounding edge of the first frame.

[0006] A further preferred embodiment of this utility model is that the plug shaft on the first frame is detachable, or the plug shaft on the second frame is detachable.

[0007] A further preferred embodiment of this utility model is: the component for adsorbing / adhering to the wall includes a suction cup, the suction cup is detachably connected, and in the folded state, the suction cup is placed inside the second frame.

[0008] Compared with the prior art, the present invention has the following advantages: When folded, the separated second frame is stacked inside the first frame, and the height of the two frames around the edges is basically the same, which minimizes the overall thickness in the folded state, makes efficient use of space, and makes the storage volume extremely small, thus greatly saving storage and transportation space.

[0012] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0013] 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.

[0014] This embodiment mainly describes the double-layer stacking shelf, as follows: like Figure 1 As shown, the double-folding shelf includes a first frame 5 and a second frame 1. The first frame 5 is larger than the second frame 1 in both length and width. Both frames are made of rigid plastic and are injection molded in one piece. They are lightweight, sturdy, and have a long service life. Each frame has a vertically extending edge 2 around its load-bearing surface to prevent items from falling off.

[0015] like Figure 2 , Figure 3 As shown, the first frame 5 and the second frame 1 are detachably connected via a connecting shaft 4 and a receiving shaft hole 6. Specifically, the ends of the first frame 5 and the second frame 1 are respectively provided with receiving shaft holes 6 extending outward. The two receiving shaft holes 6 are staggered and stacked, with the end of the second frame 1 located below the end of the first frame 5. After stacking, the connecting shaft 4 passes through the receiving shaft holes 6 simultaneously, completing the hinge connection between the first frame 5, the second frame 1, and the connecting shaft 4. Furthermore, the end of the connecting shaft 4 is provided with a locking hook 7, and the bottom of the second frame 1 is provided with a step 11. The connecting shaft 4 passes through the receiving shaft hole 6 and is locked to the second frame 1 by the locking hook 7 to stabilize the hinge connection between the connecting shaft 4 and the receiving shaft hole 6. The second frame 1 can rotate relative to the first frame 5 within the range of 0 to 180 degrees with the connecting shaft 4 as the axis, thereby forming a straight arrangement, a right-angle arrangement, or other arbitrary angle unfolded state to adapt to different corners or wall spaces.

[0016] like Figure 4 , Figure 5 As shown, both the first frame 5 and the second frame 1 are equipped with suction cups 3. The first frame 5 and the second frame 1 are adsorbed onto the smooth wall surface by the suction cups 3. Specifically, the first frame 5 and the second frame 1 are provided with inwardly extending grooves 8, and insert blocks 10 are provided in the grooves 8. The suction cup 3 extends downward and is provided with slots 9. The first frame 5 and the second frame 1 abut against each other with the grooves 8 and the lower part of the suction cup 3, so that the insert blocks 10 are aligned with the slots 9. After alignment, the corresponding frame is moved downward so that the insert blocks 10 and the slots 9 are engaged with each other, realizing the quick connection between the suction cup 3 and the frame. In this embodiment, the suction cup 3 can be a conventional rotating suction cup in the art, which will not be described in detail in this embodiment.

[0017] Working principle: like Figure 6 , Figure 7 As shown, when the user needs to store the shelf, he / she pinches the locking hook 7 at the bottom of the plug shaft 4 and squeezes the locking hook 7 inward to disengage the locking hook 7 from the step 11 at the bottom of the second frame 1, thereby releasing the locking hook 7 from the second frame 1. Then, he / she pulls the plug shaft 4 upward from the receiving shaft hole 6 with a little force. After pulling out the plug shaft 4, the first frame 5 and the second frame 1 can be separated.

[0018] The user holds the first frame 5 or the second frame 1 and applies downward force to the suction cup 3 of the corresponding frame to release the locking state between the slot 9 and the insert block 10. After removing the suction cup 3, the user places the suction cup 3 on the bearing surface of the first frame 5. Then, the user flips the separated second frame 1 so that its bearing surface faces down and places it into the bearing surface of the first frame 5. The first frame 5 is larger, so the second frame 1 can fall completely into the area enclosed by the perimeter 2 of the first frame 5. The perimeter 2 of the first frame 5 and the second frame 1 are designed to be the same height. When the second frame 1 is placed in, the upper edge of its perimeter 2 is basically at the same level as the upper edge of the perimeter 2 of the first frame 5. The perimeter 2 of the first frame 5 and the second frame 1 form a cavity to accommodate the suction cup 3, preventing the suction cup 3 from being lost during transportation.

[0019] When a user needs to use a shelf alone in a small space, the first shelf 5 or the second shelf 1 can be mounted on the wall using the suction cups 3 on its back to be used as an independent storage unit.
