[0036] The present utility model will be described in detail below with reference to the drawings and embodiments. In the written description of the present utility model, terms indicating directions are used, such as "front and back", "left and right", "up and down", etc. The terms indicating directions are only used to show the relative positional relationship of the product components and do not limit the structure and use of the product.

[0037] As Figures 1 to 4 shown, a storage cart with an expandable use space according to the present utility model includes a storage rack, an upper folding plate 5 that can slide left and right at the top of the storage rack, and two object placements 6 that divide the storage rack into upper and lower layers.

[0038] The storage rack, the upper folding plate 5, and the object placement 6 are not limited to the material, and preferably a metal material is used. The object placement 6 is described by using a storage layer board.

[0039] As Figures 1 to 5 shown, the storage rack is composed of left and right frames 1, 2 with pulleys 9 installed at the bottom, an X-shaped support frame 3 fixed to the rear sides of the left and right frames, and two U-shaped chutes 4 fixed to the tops of the left and right frames and arranged front and back; the left and right frames 1, 2 are both fixedly connected by two vertical rods A and multiple horizontally spaced-apart horizontal rods B, and a handrail C fixedly connected to the two vertical rods is provided above the left frame 1 or the right frame 2; the left and right ends of the two U-shaped chutes 4 are respectively supported on the horizontal rods B of the left and right frames 1, 2 and fixedly connected to the vertical rods A.

[0040] Furthermore, the two vertical rods A and multiple horizontal rods B of the left and right frames 1, 2 are all made of metal material, and each vertical rod A is composed of two metal thin rods. The two metal thin rods are arranged left and right and sandwich the metal horizontal rod B in the middle and are welded and fixed.

[0041] The front and rear sides of the upper folding plate 5 are respectively inserted into the U-shaped sliding grooves 4 and can move left and right along the U-shaped sliding grooves 4; as Figure 6 shown, the upper folding plate 5 is composed of two long folding plates 51 and a short folding plate 52 connected by a bearing hinge 53. The length of the long folding plate 51 is equal to the length of the two U-shaped sliding grooves 4; when a larger storage space is required for the upper folding plate 5, the long and short folding plates 51 and 52 are flattened at the top of the storage rack. When the storage cart needs to occupy a smaller space, the long folding plate 51 can be located at the top of the storage rack, and the short folding plate 52 can be vertically folded on the left or right frame side.

[0042] Magnets are embedded at the two ends of the long and short folding plates 51 and 51 away from each other, and corresponding magnets are provided at the left and right ends of the two U-shaped sliding grooves 4; when the long and short folding plates 51 and 52 are flattened at the top of the storage rack, the end of the short folding plate 51 is adsorbed to the U-shaped sliding groove 4 for limiting; when the long folding plate 51 is located at the top of the storage rack and the short folding plate 52 is vertically folded on the left frame 1 or the right frame 2 side, the end of the long folding plate 51 is adsorbed to the U-shaped sliding groove 4 for limiting.

[0043] As Figure 6 shown, a limiting stop piece D corresponding to the two U-shaped sliding grooves is provided below the end face of the short folding plate 52 at the end where the magnet is embedded. When the short folding plate 52 is inserted into the U-shaped sliding groove 4 and moves until the limiting stop piece D contacts the end face of the U-shaped sliding groove 4, it is limited, which can prevent the upper folding plate 5 from sliding out of the U-shaped sliding groove. Because the limiting stop piece D is provided below the end face of the short folding plate 52, when installing, the long folding plate 51 is first inserted into the two U-shaped sliding grooves.

[0044] As Figure 4 shown, when the short folding plate 52 is vertically folded on the left frame 1 or the right frame 2 side, the short folding plate is adsorbed on the side of the storage object 6 for positioning, and a magnet corresponding to the magnet embedded in the short folding plate 52 is provided on the side of the storage object 6.

[0045] A U-shaped card slot 61 is provided on the bottom surface of the storage object 6, and the storage object 6 is correspondingly buckled on the cross bar B of the left and right frames 1 and 2 through the U-shaped card slot 61. Alternatively, a hook is provided on the side of the storage object 6, and the storage object 6 is suspended on the cross bar B of the left and right frames 1 and 2 through the hook.

[0046] When the number of storage objects 6 is more than two, two or more storage objects 6 are any one or a combination of a storage layer board, a storage box, and a storage basket. The two storage objects 6 in this embodiment are two storage layer boards that divide the storage rack into upper and lower layers. As Figure 7 shown, a U-shaped card slot 61 is provided on the bottom surface of the storage layer board, and the storage layer board is pressed and buckled on the cross bars of the left and right frames 1 and 2, which is convenient and stable for installation.

[0047] Further, in order to prevent the items on the storage shelf from slipping, a retaining fence is provided around the storage shelf and fixed to the side of the storage rack. Baffles 7 or retaining bars 8 are provided on the front, rear, left, and right sides of the storage rack, or at least one side is provided with a retaining bar 8, and the remaining sides are provided with baffles 7. The ends of two adjacent baffles 7 are joined and fixed to the storage rack by bolts. Corresponding outer bending fixing parts E1 and inner bending fixing parts E2 are respectively provided at the ends of two adjacent baffles.

[0048] As Figures 1 to 4 shown, in this embodiment, baffles 7 are provided on the left, right, and rear sides of the storage shelf in the middle of the storage rack, and a retaining bar 8 is provided on the front side. Baffles 7 are provided around the storage shelf at the lower part of the storage rack. As Figure 8 shown, the front and rear baffles are the first baffles 71 with outer bending fixing parts E1 at both ends, and the left and right baffles are the second baffles 72 with inner bending fixing parts E2 at both ends. Designing the baffle 7 on the outer periphery of the storage shelf can prevent the items from slipping and play a protective role. The baffle 7 can be disassembled or installed as needed. The purpose of designing the retaining bar 8 is to prevent the items from slipping while not affecting the visibility of the storage space, which is convenient for placing and finding items.

[0049] When the number of the storage objects 6 of the present utility model is one, the storage object 6 is any one of a storage shelf, a storage box, and a storage basket. When the number of the storage objects 6 is more than two, the more than two storage objects 6 are any one of a storage shelf, a storage box, and a storage basket or a combination thereof.

[0050] For a storage trolley with adjustable storage space of the present utility model, the left and right frames 1, 2, the X-shaped support frame 3, the U-shaped chute 4, the upper folding plate 5, the storage object 6, the baffle 7, and the retaining bar 8 are all preferably made of metal materials.

[0051] The above embodiments are only explanations of the present utility model. Those skilled in the art can make various equivalent technical means substitutions for the technical solutions of the present utility model. Any technical solutions obtained by using the same or equivalent technical means substitutions fall within the scope of protection of the claims of the present utility model.
