Currently, there are three common types of packaging box liners: the first is a single piece of foam with multiple storage compartments carved out, the second is a one-piece plastic shell with multiple storage compartments, and the third is cardboard folded to form multiple storage compartments.

[0003] The publication number is: CN221458488U A packaging box lining and a packaging box with the packaging box lining, which are the third type mentioned above; the packaging box lining includes a face sticker, a bottom tray and at least one pit box, the pit box is a container with an open top surface, the pit box also includes wings surrounding its open top surface, a first clearance hole is opened on the bottom tray corresponding to the pit box, the pit box is placed in the first clearance hole and is placed on the bottom tray through its wings, the wings of the pit box are fit and fixed to the bottom tray, the wings of the pit box are clamped between the face sticker and the bottom tray, the wings of the pit box are fit and fixed to the face sticker, a second clearance hole is opened on the face sticker corresponding to the pit box, the top surface opening of the pit box is fully or partially exposed from the second clearance hole, the packaging box lining has a simple structure, is easy to design, process and assemble, and has low production cost.

[0004] However, according to the instructions, the pit box, surface sticker and bottom support of the lining are fixed with glue. This connection method will cause damage to the paper lining during subsequent disassembly. For example, it will cause partial falling off when torn. After multiple disassemblies, the thickness of the adhesive position will become thinner and thinner. After a certain number of times, it will be completely damaged and cannot be reused. Utility Model Content

[0005] The present invention aims to solve the problem that the prior art adopts adhesive fixation, and this connection method will cause damage to the paper lining during subsequent disassembly, for example, it will cause part of the paper lining to fall off when it is torn. After multiple disassemblies, the thickness of the adhesive position becomes thinner and thinner, and after a certain number of times, it will be completely damaged and cannot be reused. The utility model proposes the following technical solution: a lining of a packaging box, including a pallet and a storage box, the pallet is provided with a slot for the storage box to pass through, and the storage box has a limit plate that fits with one side of the pallet; the pallet is provided with a limit assembly, and the limit assembly includes a screw that passes through the pallet; a pressure strip is provided at one end of the screw, and a knob is threadedly engaged with the other end; the knob is used to enable the pressure strip to remain in a state of being pressed against one side of the pallet, so as to cooperate with the pallet to clamp the limit plate.

[0006] Among them, through the arrangement of the screw, knob and pressure strip, when the knob is turned, the pressure strip and the support plate can cooperate to clamp the limit plate of the storage box, so that the storage box and the support plate are fixed. There is no need to connect the support plate and the storage box by gluing in the existing technology, and the paper storage box will not be damaged during disassembly.

[0007] As a preferred embodiment of the above technical solution, a receiving groove is provided on the side wall of the support plate, and a support plate located at the receiving groove is provided on the side of the support plate away from the limiting plate; the support plate remains parallel to the pressure strip, and one end is hinged to the support plate; the knob is pressed against the side of the support plate away from the support plate.

[0008] The arrangement of the receiving slot and the hinged connection at one end of the support plate allows the pressure strip to rotate not only around the screw but also around the hinge of the support plate, allowing the pressure strip to be adjusted in both horizontal and vertical directions. For example, if the inner dimensions of the packaging box are larger than the dimensions of the support plate, the position of the pressure strip can be adjusted so that one end of the pressure strip is pressed against the inner wall of the packaging box, thus preventing the support plate and the storage box from shaking horizontally inside the packaging box. Figure 5 As can be seen, the accommodating slot allows the entire limiting assembly to not extend beyond the outer side of the limiting plate and to be able to move a certain distance into the accommodating slot. When the dimensions of the support plate match the inner dimensions of the packaging box, the limiting assembly can secure the storage box while not taking up space and hindering the placement of the support plate. The hinge is achieved by fasteners, such as rivets, bolts, and nuts.

[0009] As a preferred embodiment of the above technical solution, a plurality of slots are provided on the support plate, and the plurality of slots are used for receiving a plurality of storage boxes. A plurality of limiter components are provided and are respectively located on both sides of each slot.

[0010] Among them, through the provision of multiple notches, one support plate can fix multiple storage boxes to store different items.

[0011] As a preferred embodiment of the above technical solution, a fold is provided on the support plate, and the fold is located between every two notches.

[0012] Among them, the setting of the crease allows the pallet to be folded for storage. When the packaging box does not need extra slots, the excess part can be folded to adapt to the packaging box, and the folding can facilitate the transportation of the pallet itself.

[0013] As a preferred embodiment of the above technical solution, the storage box includes a box body and a limiting plate; the limiting plate is a rectangular frame and is integrally formed at the opening of the box body; the size of the limiting plate is larger than the size of the slot.

[0014] Among them, by setting the size of the limiting plate, the limiting plate can always be pressed against one side of the supporting plate and will not pass through, so that the limiting component can directly press against it.

[0015] As the preferred technical solution, the side wall of the knob is provided with a plurality of anti-skid grooves distributed circumferentially.

[0016] Wherein, through the anti-skid groove, the knob can be more easily rotated during operation.

[0017] The beneficial effects of the present application are as follows:

[0018] The present application sets the screw rod, knob and pressing strip, so that when the knob is rotated, the pressing strip cooperates with the supporting plate to form clamping with the limiting plate of the storage box, so that the storage box and the supporting plate are fixed, without connecting the supporting plate and the storage box by the existing technology of glue connection, and the paper storage box will not be damaged when disassembled.
