[0011] Preferably, a fixed block is fixedly connected to the upper surface of the top cover, a second sliding groove is provided inside the fixed block, a limiting hole is provided inside the fixed block, a sliding plate is provided inside the fixed block, the outer wall of the sliding plate is slidably connected to the inner wall of the second sliding groove, and a handle is fixedly connected to the upper surface of the sliding plate.

[0012] Preferably, a second fixing groove is provided inside the sliding plate, a third spring is provided inside the sliding plate, and one end of the third spring is fixedly connected to the inner wall of the second fixing groove.

[0014] A method for using a portable storage box includes the following steps:

[0015] S1. The flip top cover drives the push column through the first connecting column to push the first storage bin to slide out from the inner wall of the box body. When the first storage bin slides out, it pushes the baffle to rotate on the outer wall of the buffer shaft, thereby achieving the effect of fully displaying the stored items inside the box body;

[0016] S2. When the top cover is flipped, the second connecting column is driven to move by the second connecting shaft. When the second connecting column moves, it drives the first connecting shaft to slide on the inner wall of the first sliding groove. When the second connecting column moves, the first connecting shaft can drive the second storage bin to slide upward on the inner wall of the box body, thereby achieving an effect of more convenient storage and storage of items;

[0017] S3. When the card block slides into the first fixing groove, the limiting block squeezes the card block, causing it to slide inside the top cover and compress the first spring. When the card block fully enters the first fixing groove, the first spring rebounds, pushing the card block and the limiting block to engage with each other, thereby achieving the effect of quickly self-locking the storage box and preventing accidental opening from causing damage or loss of stored items.

[0018] S4. The sliding handle drives the sliding plate to slide to one side along the inner wall of the second sliding groove, and the third spring on the inner wall of the second fixing groove rebounds to push the card bead into the inner wall of the limiting hole to fix the sliding plate. This can achieve the effect of adjusting the use position of the handle during carrying, making carrying more convenient and preventing accidental touch during carrying from causing the stored items to shake and be damaged.

[0019] Working principle: When the storage box needs to be used, first press the pushing block to slide inside the top cover and push the card block to slide inside the first fixed groove. While the card block slides, it will be disconnected from the limit block. Rotate the top cover to drive the card block to slide out from the inside of the first fixed groove, and the top cover will rotate on the outer wall of the fixed shaft on the inner wall of the support plate through the outer wall sleeve of the outer wall connecting plate, so that the top cover will flip over. When the top cover flips over, it will drive the first connecting column and the pushing column of the inner bottom wall to rotate and flip. When the first connecting column drives the pushing column to flip, it will push the first storage bin to slide out on the inner wall of the box body. The sliding of the first storage bin will push the baffle to rotate on the outer wall of the buffer shaft, so that the baffle forms a platform, and the groove inside the baffle can prevent vertical movement. When the second storage bin is lifted, the sliding post on the lower surface of the second fixed plate of the outer wall slides inside the first fixed plate to achieve a limiting effect, preventing the second storage bin from tilting during the lifting process. At the same time, the blocking piece on the lower surface of the sliding post can prevent the sliding post from escaping from the inside of the first fixed plate, and the second storage bin is lifted through the second storage bin. When the outer wall of the card block completely slides into the interior of the first fixed groove, the first spring will rebound and push the card block to form a locking state with the inner wall of the first fixed groove and the limit block, thereby locking the card block, thereby preventing the box from being opened during carrying. When the storage box needs to be carried, the sliding handle drives the sliding plate to slide on the inner wall of the second slide groove, and drives the card bead to slide inside the limiting hole. When it slides to the appropriate position, the third spring on the inner wall of the second fixing groove rebounds and pushes the card bead to be fixed on the inner wall of the limiting hole. When the handle is on one side of the inner wall of the second slide groove, the handle is pulled up to drive the box body to be carried. By carrying the handle on one side of the storage box, the problem of the box body hitting the legs during walking, causing the stored items to shake, is solved, so that the storage box can be better carried. The storage box can not only fully display the items stored inside, but also facilitate the storage and retrieval of items.And when closed, it can achieve the effect of self-locking to prevent looseness during carrying, which may cause the storage box to fall out when opened. And when carrying the storage box, the position of the handle will be adjusted to prevent the box from being hit during carrying, which may cause the stored items to slide and be damaged.

[0020] The present invention provides a method for using a portable storage box, which has the following beneficial effects:

[0021] 1. The present invention rotates the top cover through the sleeve of the outer wall of the outer wall connecting plate to flip on the outer wall of the fixed shaft. At the same time, the first connecting column drives the pushing column to flip at the same time. When the pushing column flips, it will push the first storage bin to slide on the inner wall of the box body. When the first storage bin slides, it will push the baffle to rotate and open on the outer wall of the buffer shaft to form a platform, so that the first storage bin slides to the surface of the baffle, which can achieve the effect of more convenient display of items stored inside the box body.

[0022] 2. According to the present invention, when the top cover is rotated to rotate the interior of the box body, the second connecting column is driven to rotate through the second connecting shaft on the inner wall. When the second connecting column rotates, the first connecting shaft will be driven to slide on the inner wall of the first slide groove inside the second storage bin, and the first slide groove will be lifted. When the second storage bin is lifted, the sliding column on the lower surface of the second fixed plate on the outer wall slides inside the first fixed plate, which can limit the lifting of the second storage bin and prevent tilting and misalignment during the lifting process. The lifting of the second storage bin can facilitate the access to items stored in the first and second storage bins.

[0023] 3. When the top cover is rotated to close the box body, the present invention drives the card block to slide toward the inside of the first fixed groove. The limit block pushes the card block to drive the first sliding column to slide inside the top cover, and at the same time compresses the first spring. When the card block completely slides into the inside of the first fixed groove, the first spring is compressed to push the card block to slide inside the first fixed groove and form an engagement with the limit block to prevent the card block from sliding out of the first fixed groove, thereby achieving the effect of sealing the box body and preventing items from falling during use.

[0024] 4. The present invention drives the sliding plate to slide on the inner wall of the second slide groove by pulling the handle, and drives the card bead to slide inside the limiting hole at the same time. When it slides to the appropriate position, the third spring on the inner wall of the second fixing groove will rebound and push the card bead to be fixed on the inner wall of the limiting hole. When the handle is on one side of the inner wall of the second slide groove, the handle is pulled up to drive the box to be carried. By having the handle on one side, the box can be prevented from colliding with the legs during walking and carrying, thereby achieving a better effect of making the storage box more convenient to carry.
