[0022] The utility model provides Figures 1 to 4 A shelf convenient for folding and storage shown in the figure comprises a fixed frame 1 and multiple groups of support frames 2 on both sides, the support frames 2 comprise multiple groups of connecting seats 21 arranged sequentially from top to bottom on the opposite side of the fixed frame 1, the inner cavity of the connecting seat 21 is movably connected with a square tube 22 through a movable shaft, a connecting rod 23 is inserted into the inner cavity of the square tube 22, a connecting frame 24 is arranged on the opposite side of the connecting rod 23, the inner cavity of the connecting frame 24 is movably connected with one end of the connecting rod 23 away from the square tube 22 through a movable seat, a placing plate 3 is clamped on the top of the square tube 22, a position adjustment component 4 for limiting the connecting rod 23 is arranged in the inner cavity of the square tube 22, and is used to adjust the telescopic movement of the connecting rod 23 in the square tube 22 and lock it, and a universal wheel with a locking structure can be installed at the bottom of the fixed frame 1;

[0023] By adjusting the support frame 2, the purpose of reducing space is achieved. The connecting rod 23 can be telescopically moved in the square tube 22 to make the fixed frames 1 on both sides close to each other, and then the square tube 22 can be rotated in the connecting frame 24, and the connecting rod 23 is movably connected through the connecting frame 24, so that the support frame 2 can be further folded to shorten the distance between the fixed frames 1. At the same time, the structure of the shelf after folding and storage is stable, not easy to loose, and easy to transport and store. At the same time, the larger placement board 3 can be folded in half by the hinge to reduce the space occupied by the placement board 3.

[0024] The position adjustment component 4 includes a plurality of storage holes 41 provided on the outside of the square tube 22, a positioning hole 42 provided on the surface of the connecting rod 23, a positioning pin 43 inserted into the inner cavity of the storage hole 41, and a pull ring movably provided on the outer side of the tail of the positioning pin 43 to facilitate the removal of the positioning pin 43 from the storage control, one end of the positioning pin 43 penetrates into the inner cavity of the square tube 22 and is engaged with the positioning hole 42, and the positioning pin 43 penetrates the storage hole 41 and the positioning hole 42 to facilitate the limiting of the connecting rod 23 and the square tube 22 to ensure the stability between the connecting rod 23 and the square tube 22, and at the same time, the position of the connecting rod 23 can be adjusted to facilitate the telescopic storage of the connecting rod 23.

[0025] The placement board 3 includes two groups of symmetrical frame boards 5, and the opposite sides of the frame boards 5 are hinged by hinges. By setting the structure of the placement board 3, it is convenient to reduce the size of the space occupied by the placement board 3 by folding.

[0026] A card slot 6 is provided on the top of the fixing frame 1, and a card block 7 is carded into the inner cavity of the card slot 6. The opposite side of the card block 7 penetrates to the outside of the fixing frame 1 and is fixedly connected to the top connecting seat 21. By card block 7 being carded into the inner cavity of the card slot 6, the top connecting seat 21 is separated from the fixing frame 1, thereby preventing the top square tube 22 from folding upward to increase the height of the shelf.

[0027] A first support rod 8 is fixedly connected to one side of the front and rear square tubes 22 facing each other, and a second support rod 9 is fixed to one side of the connecting frame 24 facing each other.

[0029] A plug hole 12 is provided on the surface of the fixing frame 1, and a fastener 13 is clamped in the inner cavity of the plug hole 12. After folding, the distance between the fixing frames 1 on both sides is the same as the distance between the two groups of plug holes 12 on the single-side fixing frame 1, so that the fastener 13 can be conveniently fixed to the single-side fixing frame 1 to prevent the fastener 13 from being lost. Through the setting of the fastener 13 and the plug hole 12, when the fixing frame 1 of the folding shelf is connected, the square tube 22 can be prevented from falling due to gravity, and the fixing frame 1 can be supported and unfolded again to ensure that the folded shelf remains stable.

[0030] During specific use, the placement plate 3 is removed from the support frame 2, and the placement plate 3 is folded and stored by the hinge, and then the positioning pin 43 in the storage hole 41 is removed, and the fixing frame 1 is moved inward to make the connecting rod 23 shrink into the square tube 22. When the connecting rod 23 is completely retracted into the square tube 22, the positioning pin 43 is used to lock the connecting rod 23 and the square tube 22, and at the same time, the connecting frame 24 is pulled upward, and the square tube 22 rotates in the connecting seat 21. At the same time, the connecting rod 23 is folded in the connecting frame 24, so that the fixing frames 1 are close to each other, and finally the top support frame 2 is separated from the fixing frame 1 by the block 7 and the slot 6, and then the fasteners 13 are inserted into the slots on the surfaces of the fixing frames 1 on both sides to limit the folded shelves.
