The support frame 1 includes a base plate 11 and two side plates 12 fixed to the left and right sides of the base plate 11. The top surface of the storage box 3 is provided with a box opening, and the left and right sides of the storage box 3 are respectively rotatably mounted to the two side plates 12 via a rotating shaft assembly 4. The front baffle 2 extends vertically, and its left and right sides are respectively fixed to the two side plates 12. The front baffle 2 is located on the front side of the storage box 3, and the height of the upper edge of the front baffle 2 is lower than the height of the upper edge of the storage box 3.

[0031] Based on the above structure, the storage rack provided in this embodiment allows the storage box 3 to be rotated so that its opening faces forward at an angle, facilitating the retrieval of books (or other items from storage bags) from backpacks. The upper edge of the front baffle 2 is lower than the upper edge of the storage box 3, limiting the forward and backward rotation angle of the storage box 3. This ensures that the storage box 3 will not tip backward when upright or forward when rotated. The specific height of the upper edge of the front baffle 2 compared to the upper edge of the storage box 3 is designed according to the angle at which the storage box 3 can flip forward. This flip angle can be selected, but is not limited to, 30°, 45°, 50°, or any angle between 30° and 50°, with 45° being the optimal design angle for user convenience. The base plate 11 has a front-opening retrieval space above it, which can be used to place small bookshelves, books, computer cases, etc., improving the space utilization of the storage rack.

[0032] In this embodiment, the specific fixed connection methods between the bottom plate 11 and the side plate 12, and between the side plate 12 and the front baffle 2, include but are not limited to fixed connection methods such as screw connection or snap-fit ​​connection; the height of the lower edge of the front baffle 2 may be lower than the height of the bottom surface of the storage box 3 or flush with the height of the bottom surface of the storage box 3.

[0033] In this embodiment, the pivot assembly 4 has a variety of optional structural types, including but not limited to having the pivot assembly include two shafts that are respectively fixedly connected to the left and right side walls of the storage box 3. These two shafts are inserted into the insertion holes provided on the side plate to achieve rotational installation. Alternatively, the pivot assembly 4 can be designed in other ways to facilitate transportation and user assembly after delivery, while ensuring the structural stability and load-bearing performance of the storage rack.

[0034] Reference Figure 2 , Figure 7 , Figure 8 , Figure 9 and Figure 10In an optional embodiment of this example, the rotating shaft assembly 4 includes a rotating cover 41, a rotating shaft 42, and a screw 43. Specifically: the rotating cover 41 includes a rotating cover body 411 and a rotating cover flange 412 located at one axial end of the rotating cover body 411 and extending radially outward along the rotating cover body 411; the rotating shaft 42 includes a rotating shaft body 421 and a rotating shaft flange 422 located at one axial end of the rotating shaft body 421 and extending radially outward along the rotating shaft body 421. The storage box 3 has an outwardly extending mounting protrusion 31 on its side wall. The mounting protrusion 31 has a rotating cover mounting hole 311 in the middle. The rotating cover body 411 has a pivot mounting hole 4111 in the middle. The rotating cover body 411 is inserted into the rotating cover mounting hole 311. The rotating cover edge 412 is pressed between the side plate 12 and the mounting protrusion 31. The pivot body 421 is rotatably inserted into the pivot mounting hole 4111 in the middle of the rotating cover body 411. The pivot edge 422 is attached to the inner surface of the side wall of the storage box 3. The end of the pivot 42 away from the storage box 3 is fixedly connected to the side plate 12 by a screw 43.

Then, the rotating shaft 42 is fixed to the side plate 12 by screws 43. When disassembling, the screws 43 are removed. The whole process is convenient for disassembly and assembly and the structure is stable.

[0036] Reference Figure 10 In an optional embodiment of this example, one of the inner wall of the rotating cover mounting hole 311 and the outer peripheral surface of the rotating cover body 411 is provided with a limiting protrusion 51 and the other is provided with a limiting groove 52. The limiting protrusion 51 and the limiting groove 52 are in a concave-convex fit and prevent the rotating cover 41 from rotating relative to the rotating cover mounting hole 311. That is, in this optional embodiment, the rotating cover 41 and the mounting protrusion 31 cannot rotate relative to each other, and the rotating shaft 42 is fixedly connected to the side plate 12 by screws 43. Thus, when the storage box 3 is flipped, the rotating cover 41 rotates with the storage box 3 relative to the rotating shaft 42, so as to achieve stable flipping.

At any rotating position, each arc-shaped protrusion 54 is engaged with an arc-shaped groove 53, so that the rotating cover 41 and the pivot 42 are relatively fixed, which plays a positioning function. When a flipping force is applied to the storage box 3, the flipping force can cause the arc-shaped protrusion 54 to slide out from the edge of the arc-shaped groove 53 until it is positioned to the next rotating position, so as to change the rotation angle of the storage box 3.

[0038] Reference Figure 2 , Figure 7 , Figure 8 , Figure 9 and Figure 10 In an optional embodiment of this example, the pivot assembly 4 further includes a side cover 44; the inner side of the side plate 12 is provided with a second mounting groove 1202 and the outer side is provided with a first mounting groove 1201, and an isolation plate 1203 is provided between the bottom of the second mounting groove 1202 and the bottom of the first mounting groove 1201; the end of the pivot 42 away from the storage box 3 is located inside the first mounting groove 1201; the head of the screw 43 is located in the second mounting groove 1202, and the shank of the screw 43 passes through the isolation plate 1203 and is threadedly connected to the pivot 42; the side cover 44 is fixed to the inner wall of the second mounting groove 1202 and covers the second mounting groove 1202. In this optional embodiment, by designing the second mounting groove 1202 and the side cover 44, the screw 43 can be protected to prevent accidental contact that could loosen the storage rack. On the other hand, it also has a dustproof effect and increases the aesthetics of the screw-in area of ​​the storage rack.
