[0002] A car is composed of a frame, an engine, and tires. In order to facilitate the transfer of small batches, turnover boxes are usually used in tire processing workshops for transfer, so that multiple tires can be transferred at a time.

[0003] After searching, the utility model with announcement number CN220885162U discloses a foldable turnover box, which is used to constrain two adjacent first joints through an elastic limit ring on the one hand, and on the other hand, allows the two adjacent first joints to rotate relative to each other, thereby changing the relative angle; by pressing the movable frame, the direction of the hinge assembly is changed, thereby folding the movable frame, which is conducive to modular production and reduces the production, transportation and storage of turnover boxes and their parts; it is conducive to the folding and storage of turnover boxes.

[0004] The turnover box also has the following disadvantages when rotating tires: the tires are placed in the turnover bag and cannot be effectively fixed, and if they are not isolated, friction will occur between the tires during the shaking process, affecting the sales of the tires, and the process of moving requires manual lifting, which is inconvenient to use. Therefore, it is very necessary to propose a lightweight and portable turnover box. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. It should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "setting" should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0030] Reference Figure 1-Figure 5A lightweight and portable turnover box includes a chassis 1 and a plurality of partitions 5. The top of the chassis 1 is rotatably provided with two first frames 2 and two second frames 3, which can be opened by rotation to form a box body, which is convenient for loading tires. Rollers 4 are fixed at the four corners of the bottom of the chassis 1 to facilitate the movement of the turnover box.

[0031] A plurality of rectangular holes 9 are provided on the top of the chassis 1 for positioning the tire. A limiting mechanism is provided in each rectangular hole 9 for clamping and fixing the tire.

[0032] The limiting mechanism includes a sliding plate 14 at the bottom of the chassis 1, two guide rods 13 are fixedly provided at the bottom of the chassis 1, the sliding plate 14 is slidably sleeved on the two guide rods 13, a plurality of groups of L-shaped plates 15 are fixedly provided on the sliding plate 14, a first fixing block 17 is provided on the top of the L-shaped plate 15, a clamping portion 18 is provided on the first fixing block 17, an extension plate 19 is provided on the top of the clamping portion 18, when the clamping portion 18 is not in use, the top of the extension plate 19 is flush with the rectangular hole 9. When the tire is placed, the tire will squeeze the two rectangular holes 9 to expand outward until the clamping portion 18 corresponds to the hollow position of the tire, and the tire can be fixed by the clamping portion 18, which is more stable during transportation.

[0033] In order to fix the first frame 2 and the second frame 3 after opening, a fixing device is used, including two connecting tubes 8 arranged on the outside of the first frame 2 and the second frame 3. A latch 7 is slidably provided in the connecting tube 8 on the second frame 3, and the other end of the latch 7 is plugged into the connecting tube 8 on the first frame 2, thereby fixing the frame.

[0034] The first frame 2 and the second frame 3 are connected to the chassis 1 via a rotating block 6, and the rotating point between the second frame 3 and the rotating block 6 is higher than the rotating point between the first frame 2 and the rotating block 6. This design prevents the frames from interfering with each other after being stored.

[0035] In order to isolate the tires, multiple partitions 5 are arranged between the two first frames 2, and the partitions 5 are located between two adjacent rectangular holes 9. In addition, a first pull rope 10 corresponding to the partition 5 is also provided between the first frames 2, and a sleeve 11 is sleeved on the first pull rope 10. Multiple partitions 5 are arranged on the sleeve 11 to facilitate adjustment of the position of the partition 5. When the first pull rope 10 is loosened during the storage process, the partition 5 will automatically dump onto the chassis 1.

[0036] An elastic portion 16 is provided at the upper end of the L-shaped plate 15, and a second pull rope 12 is fixedly provided between the elastic portion 16 and the first frame 2. When the first frame 2 is opened, the elastic portion 16 is pulled upward by the second pull rope 12, thereby driving the clamping portion 18 to rise. A protrusion 20 is provided at the bottom of each group of L-shaped plates 15. After storage, the protrusion 20 contacts the ground to brake the turnover box to prevent it from rolling.

[0037] Working principle: when in use, first open the two second frames 3, and then open the two first frames 2. During the opening process, the two first frames 2 can tighten the first drawstring 10 and pull the partition 5 to stand up. At the same time, the L-shaped plate 15 can be driven to move upward through multiple second drawstrings 12, and the elastic part 16 on the L-shaped plate 15 is deformed, so that the outer side of the elastic part 16 is in contact with the rectangular hole 9, and then one end of the latch 7 is inserted into the corresponding connecting tube 8. At this time, the turnover box is opened;

[0038] Then, the tire is placed between the partitions 5 and the partitions 5 and between the partitions 5 and the second frame 3. During the downward placement of the tire, the two extension plates 19 can be deformed and expanded outward until the tire contacts the two elastic parts 16. At this time, the clamping part 18 is stuck in the tire to fix the tire.

[0039] After use, take out the latch 7 and fold the first frame 2 and the second frame 3. During the folding process, the partition 5 can fall onto the chassis 1 under gravity. At the same time, the elastic part 16 will be reset and move downward under gravity until the protrusion 20 hits the ground, thereby braking the folded turnover box.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
