[0024] refer to Figure 1 , which shows a schematic diagram of the structure of an express box proposed according to an embodiment of the present application. The express box 100 of the present application is configured as a foldable express box, and after folding, the structure of the express box 100 itself can be used to stabilize the express box 100 in a folded state, so as to facilitate the storage of the express box 100. The express box 100 includes a box body 1 and a box cover 2 that cooperates with the box body 1. For the sake of convenience, the direction from the box body 1 to the box cover 2 of the express box 100 is defined as the direction from bottom to top. Figure 1 In the embodiment, a first sleeve 101 is provided on the opening edge of the box body 1, and a second sleeve 201 cooperating with the first sleeve 101 is provided on the corresponding edge of the box cover 2. When the express box 100 is in a sealed state, the first sleeve 101 and the second sleeve 201 cooperate to form a first connecting sleeve 10, and a connecting rod 3 is inserted in the first connecting sleeve 10 to connect the box cover 2 and the box body 1 together, thereby realizing the sealing between the box cover 2 and the box body 1.

[0025] The box cover 2 includes a first sub-box cover 21 and a second sub-box cover 22 adjacent to each other. In addition to the second sleeve 201 matching the opening edge of the box body 1 being provided on the edge of the two sub-box covers, sleeves are also provided on the edges adjacent to each other of the two sub-box covers, that is, the first sub-box cover 21 is provided with a third sleeve 211 on its edge adjacent to the second sub-box cover 22, and the second sub-box cover 22 is provided with a fourth sleeve 221 matching the third sleeve 211, and the third sleeve 211 and the fourth sleeve 221 cooperate to form a second connecting sleeve 20, and a connecting rod 3 is inserted in the second connecting sleeve 20 (that is, the connecting rods of the same structure are inserted in the second connecting sleeve 20 and the first connecting sleeve 10), thereby, the connecting rod 3 connects the first sub-box cover 21 with the second sub-box cover 22, thereby realizing the encapsulation of the box cover 2 itself. Through the form of this split box cover, it is easier to open and close the express box 100. When the express box 100 needs to be opened, the connecting rod 3 is removed from the second connecting sleeve 20. When the side is not connected to the box body 1, the first sub-box cover 21 and the second sub-box cover 22 can be opened upward. When the express box 100 as a whole needs to be folded, the sub-box cover can still be connected to the express box 100 in the open state without being removed to prevent loss. At the same time, the first sub-box cover 21 and the second sub-box cover 22 are connected by the second connecting sleeve 20 and the connecting rod 3, which also ensures the sealing of the box cover 2.

[0026] In one embodiment of the present application, the box body 1 is designed as a rectangular box body, for example, and includes a bottom plate 11 and a first group of side plates 12 and a second group of side plates 13 connected to the bottom plate 11 and arranged symmetrically. The second connecting sleeve 20 is arranged perpendicular to the first group of side plates 12, and the second connecting sleeve 20 is especially arranged in the middle of the entire box cover 2, that is, the first sub-box cover 21 and the second sub-box cover 22 are arranged to have the same size. A first sleeve 101 is arranged on the edge of the first group of side plates 12, and the first sub-box cover 21 and the second sub-box cover 22 are respectively matched to the first group of side plates 12 through the second sleeve 201 constructed thereon.

[0027] exist Figure 1In the embodiment, the first sleeve 101 is constructed on all the opening edges of the box body 1, that is, the first sleeve 101 is constructed on the upper edges of the first group of side panels 12 and the second group of side panels 13 facing the box cover 2. In this case, the two first connecting sleeves 10 formed by the second group of side panels 13 and the box cover 2 and the connecting rod 3 can be fixedly connected by interference connection, welding, bonding, etc., because the connecting rod 3 in the two first connecting sleeves 10 formed by the second group of side panels 13 and the box cover 2 does not need to be taken out when the express box 100 is folded. It should be understood that the first sleeve 101 can also be arranged only on the first group of side panels 12, that is, the box cover 2 as a whole is connected to the box body 1 through the sleeve only through a pair of edges, and the other two edges of the box cover 2 are, for example, integrally formed with the second group of side panels 13, and can be folded relative to the second group of side panels 13. This embodiment is more suitable for the case where the box cover 2 is made of flexible material.

[0028] In the above embodiment, the second sleeve 201 on the box cover 2 is arranged to protrude upward along the outer edge of the box cover 2, and the third sleeve 211 of the first sub-box cover 21 and the fourth sleeve 221 of the second sub-box cover 22 are also arranged to protrude upward from the box cover 2. In an embodiment not shown, the third sleeve 211 of the first sub-box cover 21 and the fourth sleeve 221 of the second sub-box cover 22 can also be arranged to protrude downward from the box cover 2. Thus, when the express box 100 is packaged, the second connecting sleeve 20 does not protrude upward from the box cover 2, but is hidden inside the express box 100, so as to be more conducive to pasting the express bill on the box cover 2.

[0029] In one embodiment of the present application, the first group of side panels 12 and the second group of side panels 13 are made of flexible materials, such as TPU. TPU is thermoplastic polyurethane, and has good wear resistance, tensile properties, tearing properties, flexural properties, hydrolysis resistance, high temperature resistance and oxidation resistance, so that the service life of the express box 100 is longer, and the TPU material is an environmentally friendly material. When the service life of the express box 100 is reached, it can be recycled and degraded to achieve the purpose of environmental protection. When both groups of side panels are formed by flexible materials, the two side panels in the first group of side panels 12 and the second group of side panels 13 can be folded toward each other, and the flexible material can also have a certain elasticity, so that the folded express box can be easily restored to its original state when it needs to be used again. Further, the first sleeve 101 and the second sleeve 201 are also made of flexible materials, which is not only conducive to reducing the weight of the express box 100, but also convenient for the storage of the express box 100 after folding, and can reduce the necessary storage space. Further, the box cover 2 and the bottom plate 11 can also be made of flexible materials, for example.

[0030] In one embodiment of the present application, a plurality of first sleeves 101 evenly spaced from each other are arranged on the first group of side panels 12, and a plurality of second sleeves 201 evenly spaced from each other are arranged on the box cover 2. In this way, the first sleeve 101 and the second sleeve 201 can be arranged in a staggered manner when they cooperate with each other, and the strength of the connection can be improved when they are connected by the connecting rod 3, so that when one or more of the first sleeves 101 or the second sleeve 201 is damaged or broken, the box cover 2 and the box body 1 can still remain connected. In one embodiment of the present application, the interval length between two adjacent first sleeves 101 is the length of the second sleeve 201, and the interval length between two adjacent second sleeves 201 is the length of the first sleeve 101, and the first sleeve 101 and the second sleeve 201 are staggered when they cooperate with each other. This matching method ensures the sealing of the sleeve at the matching point, which is conducive to the packaging of liquids or easily leaked items in the express box 100. In one embodiment of the present application, for example, there are 3 first sleeves 101 on a single side plate, and there are 4 second sleeves 201 matched therewith. In addition, for example, the two sleeves at the end of the first connecting sleeve 10 are configured to be smaller than other sleeves, so that a better sealing effect can be achieved. Of course, it should be understood that when applied to a general solid object, if there is no sealing requirement, the interval length between adjacent first sleeves 101 and the interval length between adjacent second sleeves 201 can also be set wider. In one embodiment of the present application, a plurality of third sleeves 211 arranged evenly spaced from each other are also provided on the first sub-box cover 21, and a plurality of fourth sleeves 221 arranged evenly spaced from each other are also provided on the second sub-box cover. It can also be set that the interval length between two adjacent third sleeves 211 is the length of the fourth sleeve 221, and the interval length between two adjacent fourth sleeves 221 is the length of the third sleeve 211, and the third sleeve 211 and the fourth sleeve 221 are staggered when they cooperate with each other.

[0031] In one embodiment of the present application, the second set of side panels 13 includes a first side panel 131 and a second side panel 132, and three outwardly protruding plug sleeves 133 are arranged on the outer walls of the first side panel 131 and the second side panel 132, respectively. The plug sleeve 133 of the first side panel 131 and the plug sleeve 133 of the second side panel 132 are arranged in a corresponding position, and the connecting rod 3 can be inserted into the plug sleeve 133. The plug sleeve 133 is provided to better fix the shape of the express box 100 after the express box 100 is folded. Before folding the express box 100, the connecting rod 3 in the two first connecting sleeves 10 formed by the first set of side panels 12 and the box cover 2 and the connecting rod 3 in the second connecting sleeve 200 are removed, and the second set of side panels 13 are relatively folded onto the bottom plate 11. The plug-in sleeves 133 on the first side panel 12 and the second side panel 13 are arranged so that, in this case, each of the three connecting rods 3 can be inserted into a plug-in sleeve 133 of the first side panel 131 and a corresponding plug-in sleeve 133 of the second side panel 132, pressing the first group of side panels 12 and the second group of side panels 13 onto the bottom panel 11, thereby preventing the express box 100 from recovering to its original shape due to its elasticity after being folded or preventing the folded express box 100 from being deformed due to squeezing or the like.

[0032] The folded express box 100 can be referenced Figure 2 , which shows a top view of a folded express box 100 according to an embodiment of the present application. When the express box 100 needs to be folded after use, first remove the connecting rods 3 in the two first connecting sleeves 10 formed by the first set of side panels 12 and the box cover 2, then remove the connecting rods 3 in the second connecting sleeve 20, then fold the second set of side panels 13 relatively onto the bottom plate, and finally insert the removed three connecting rods 3 into the plug sleeves 133 of the first side panel 131 and the second side panel 132 of the second set of side panels 13 in sequence.

[0033] In one embodiment of the present application, a fixed sleeve 102 is provided at the junction of each side panel with other side panels and the bottom panel, and a support rod 4 is accommodated in the fixed sleeve 102. The fixed sleeve 102 and the support rod 4 are provided to increase the rigidity and strength of the express box 100 when in use, especially when the side panels are made of flexible materials. When the box body 1 is subjected to external pressure during use, the support rod 4 and the fixed sleeve 102 can withstand the external pressure to prevent the box body 1 from being easily compressed and deformed due to the external pressure, thereby causing the items in the box body 1 to be squeezed and damaged. The support rod 4 generally does not need to be removed from the fixed sleeve 102, so the support rod 4 can be fixedly connected to the fixed sleeve 102 by interference connection, welding or bonding.

[0034] In one embodiment of the present application, buffering protrusions 5 arranged side by side are also provided on the first group of side panels 12, the second group of side panels 13, the bottom plate 11 and the box cover 2, and the buffering protrusions 5 are composed of multiple layers of buffering materials. The buffering material is, for example, TPU, foam, rubber, etc., and is especially arranged in layers along the protruding direction of the buffering protrusion 5, which can buffer the collision, thereby protecting the items inside the express box 100 from damage. The buffering protrusion 5 can also be integrally injection molded with the box body 1 and the box cover 2, in which case the buffering protrusion as well as the box body 1 and the box cover 2 can be made of TPU. This buffering protrusion 5 is preferably arranged on the inner side of each plate facing the inside of the box body. Of course, as needed, this buffering protrusion can also be arranged on the outside of a specific plate to further enhance the buffering effect. In the buffer protrusion 5 arranged on the bottom plate 11, there are correspondingly provided reinforcement sleeves 51 extending in directions perpendicular to the first set of side panels 12 and in directions parallel to the first set of side panels 12. Reinforcement rods are inserted into the reinforcement sleeves 51 extending in directions perpendicular to the first set of side panels 12 and in directions parallel to the first set of side panels 12. The reinforcement structure formed in this way can make the bottom plate 11 of the box body 1 have higher rigidity and strength. It is suitable for situations where the weight of the items transported by the express box 100 is large, so that the bottom plate 11 of the box body 1 can carry heavy items without damage. Figure 1 For the sake of clarity, in the embodiment of FIG. 1 , the buffer protrusion 5 constructed outside the first group of side panels 12 is exemplarily shown. Two rows of buffer protrusions 5 evenly spaced apart are constructed on the first group of side panels 12 . Each row of buffer protrusions 5 has three buffer protrusions 5 evenly spaced apart. Figure 3, which shows a bottom view of an express box proposed according to an embodiment of the present application as viewed from the bottom plate. The buffer protrusions 5 constructed on the bottom plate 11 are also constructed in two rows, with three buffer protrusions 5 in each row. The buffer protrusions 5 are, for example, arranged in the shape of a cuboid, and each buffer protrusion 5 on the bottom plate is provided with a reinforcement sleeve 51 extending perpendicular to the direction of the first group of side panels 12 and in a direction parallel to the first group of side panels 12, wherein one reinforcement sleeve is arranged on the side of the cuboid, and the other is arranged on the bottom surface of the cuboid away from the box body 1, so that the reinforcement rods will not hinder each other when inserted. After being inserted, the reinforcement rods form a 2 horizontal and 3 vertical reinforcement structure, thereby strengthening the rigidity and strength of the bottom plate 11 and increasing the load-bearing capacity and pressure resistance of the express box 100. It should be understood that the second set of side panels 13 and the box cover 2 are also provided with the same buffer structure as that on the first set of side panels 12, and the buffer protrusion 5 can be arranged on the outside of the box body 1 or the box cover 2, or on the inside of the box body 1 or the box cover 2, or on both the outside and inside of the box body 1 or the box cover 2. The buffer protrusion 5 on the box cover 2 is generally arranged on the inside, that is, the side of the box cover 2 facing downward, because it may be necessary to leave space on the box cover 2 for pasting a courier bill or a QR code. Of course, depending on the different structural dimensions of the express box 100, a buffer protrusion 5 can also be provided on the outside of the box cover 2.

[0035] In one embodiment of the present application, a heat-insulating layer is provided on the inner wall of the box body 1 and the box cover 2. The provision of the heat-insulating layer can prevent heat exchange between the inside and outside of the box body 1 to a certain extent, and is suitable for transporting items that require heat preservation or low-temperature preservation. The presence of the heat-insulating layer enables the express box 100 to be used as a take-out box. For example, a heat-insulating space separated from the internal space of the box body 1 can also be provided on the box body 1, and a heat source or ice cubes can be arranged in the heat-insulating space to keep the items inside the box body 1 warm or keep them fresh at low temperatures.

[0036] It should be understood that all the above preferred embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of the present application should be within the legal protection scope of the present application.
