[0002] With the deepening of modern industrialization, logistics technology has gradually become a very important part of product circulation. As a commonly used transport packaging device in logistics production, the panel box is usually composed of a bottom pallet, a panel and a box cover. The panel is formed by hot-melt connection between multiple panels to form a whole. This design allows the panel box to be folded when not in use, which greatly saves storage space. In the prior art, there is a demand for impact resistance and corrosion resistance for the panel box, and the panels of the panel box need to be able to be bent at the corners of the splicing to be assembled with the pallet. The materials of the panels and pallets of the panel box are mostly lightweight and high-strength PP polypropylene plastic. Although PP polypropylene plastic is convenient for bending and forming the panels, the panels made of PP polypropylene plastic have a short service life and are prone to failure and breakage caused by aging. Therefore, improvements have been made in the prior art, using PP polypropylene plastic for the enclosures and HDPE high-density polyethylene plastic for the pallets. However, although this solution extends the service life of the pallets, it leads to inconsistencies in the service life of the pallets and the enclosures. When the pallets are not aged, the enclosures have aged to the point of failure and cracking, so that the service life of the pallets and the enclosures needs to be checked regularly, which undoubtedly increases the workload.

[0003] Furthermore, in the prior art, the production of blister panels and pallets is customized, and molds need to be opened according to specific sizes. Each template can only be used for a single panel size, and the mold adaptation rate is low, the mold opening cycle is long, and the mold cost is high.

DETAILED DESCRIPTION

[0017] In order to make the purpose, principle and structure of the present invention more clear, it is further described below in conjunction with the drawings and specific embodiments.

[0018] Embodiment 1: This embodiment provides a panel box with adjustable height and length, comprising: The pallet and the enclosure are provided with a slot. After the enclosure is bent, the lower end of the enclosure matches with the slot of the pallet. On the basis of the snap connection, the pallet and the enclosure can also be welded at the slot. The pallet and the enclosure are made of HDPE material with the same material properties, aging degree and service life.

[0019] See also Figures 1 to 5The enclosure includes: a first enclosure 1, a second enclosure 2 and a plurality of extension enclosures 3. The first enclosure 1 and the second enclosure 2 can be connected to form an integral structure through the extension enclosure 3 after being bent. The first enclosure 1 and the second enclosure 2 have the same structure, shape and size. The structure of the first enclosure 1 is described in detail below.

[0020] The first enclosure 1 includes a first side panel 1.1 and a second side panel 1.2 of the same width, the two side panels are connected to each other and a first groove 1.5 is provided at the connection, and the first side panel 1.1 and the second side panel 1.2 perform opening, closing and folding movements with the first groove 1.5 as the rotation center. The other side of the first side panel 1.1 is connected to a third side panel 1.3, and two grooves 1.6 with intervals are provided at the connection between the first side panel 1.1 and the third side panel 1.3. Similarly, the other side of the second side panel 1.2 is connected to a fourth side panel 1.4, and two grooves 1.6 with intervals are provided at the connection between the second side panel 1.2 and the third side panel 1.3. The first side panel 1.1 and the third side panel 1.3, the second side panel 1.2 and the fourth side panel 1.4, can all perform bending movements along the two grooves 1.6 with intervals, and a protrusion can be left at the interval between the two grooves, and the protrusion is the same as the thickness of the plurality of side panels, forming a reinforcing protrusion structure at the corner bend, providing support for the two adjacent side panels at the connection.

[0021] The other side of the third side panel 1.3 and the fourth side panel 1.4 can be directly connected, or can also be connected with a plurality of extended panels 3, the length and number of which can be dynamically adjusted according to demand. The size of the folded panel box in the width direction is fixed, and its width is the width of the first side panel 1.1 and the second side panel 1.2, but in the length direction, the length and number of the extended panels 3 can be dynamically adjusted to achieve the adjustability of the panel box in the length direction, and since only the extended panels 3 need to be adjusted to achieve the adjustment in the length direction, the size of the first panel 1 and the second panel 2 is fixed, thereby reducing the need for mold opening in the width direction, and in the length direction, only the number of extended panels 3 or the mold of the extended panels 3 needs to be adjusted to achieve customized production of the panel box.

[0022] Furthermore, reinforcing ribs are embedded in the enclosure near the first groove 1.5 and the two grooves 1.6 with intervals, so as to enhance the structural strength of the enclosure.

[0023] Since the enclosure is an integral structure and is provided with two bendable grooves 1.6 with intervals and a foldable first groove 1.5, the enclosure can still maintain a good folding function when using the same HDPE high-density polyethylene plastic as the pallet. On the premise of ensuring the folding function remains unchanged, the materials of the enclosure and the pallet are consistent, and their aging degrees can also be consistent, avoiding the aging of the pallet and the enclosure at different times and reducing the need for regular quality inspections of the enclosure box.

[0024] The cover plate is composed of a first cover plate 5, a second cover plate 6, a third cover plate 7 and a plurality of extension cover plates 8. The first cover plate 5 and the third cover plate 7 are of the same shape and size and are symmetrically arranged, and a groove is provided on the periphery of the bottom thereof to match the contour of the enclosure structure. The second cover plate 6 is located between the first cover plate 5 and the third cover plate 7, and a groove is also provided on the periphery of the bottom thereof to match the contour of the enclosure structure. A plurality of extension cover plates 8 connected to each other are also provided between the first cover plate 5 and the second cover plate 6 and between the second cover plate 6 and the third cover plate 7 to form a cover plate structure adjustable in length. The periphery of the bottom of the extension cover plate 8 is also provided with a groove to match the contour of the enclosure structure. The bottom of the entire length-adjustable cover plate structure forms a cover plate groove composed of the grooves of the first cover plate 5, the second cover plate 6, the third cover plate 7 and the extension cover plate 8, and the cover plate groove matches the contour of the enclosure structure adjustable in length.

[0025] The pallet is composed of a first pallet 9, a second pallet 10, a third pallet 11 and a plurality of extension pallets 12. The first pallet 9 and the third pallet 11 are of the same shape and size and are symmetrically arranged, and grooves are provided on the top periphery thereof to match the contour of the enclosure structure. The second pallet 10 is located between the first pallet 9 and the third pallet 11, and grooves are also provided on the top periphery thereof to match the contour of the enclosure structure. A plurality of extension pallets 12 are also provided between the first pallet 9 and the second pallet 10 and between the second pallet 10 and the third pallet 11 to form a pallet structure adjustable in length. The top periphery of the extension pallet 12 is also provided with grooves to match the contour of the enclosure structure. A tray groove composed of the grooves of the first pallet 9, the second pallet 10, the third pallet 11 and the extension pallet 12 is formed on the top of the entire length-adjustable pallet structure, and the tray groove matches the contour of the length-adjustable enclosure structure.
