[0049] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0050] One embodiment of the present invention relates to a panel box 100. Figure 1 、 Figure 2 、 Figure 3 As shown, the panel box 100 includes a base 1 and a plurality of detachably connected panels, which are sequentially connected to form a storage space around the base 1. At least one of the multiple panels has a first plate 21 and a second plate 22 that are sequentially connected and located on different sides of the panel box, wherein the first plate 21 and the second plate 22 are connected by a bend. The panel box also includes a first connecting fastener 4 and a second connecting fastener 5 that snaps into contact with the first connecting fastener 4. Two adjacent panels have a first free side and a second free side that are opposite each other. The first connecting fastener 4 is connected to the first free side, and the second connecting fastener 5 is connected to the second free side.

[0051] In addition, the coaming box 100 further includes a box cover 6 for covering the accommodation space.

[0052] Since multiple panels are provided, the multiple panels are connected in sequence to form a storage space around the base 1, that is, multiple independent panels are connected by the first connecting fastener 4 and the second connecting fastener 5 to form an integral sleeve-shaped plate, and each panel is not a surrounding sleeve-shaped structure. When in use, some panels can be installed first, and after the goods are placed, the remaining panels can be installed on the base 1 from the side of the goods, so that the adjacent panels are connected by the first connecting fastener 4 and the second connecting fastener 5. The panels do not need to be put on the top of the goods, which makes installation more convenient. You can also put the goods first, and then install the panels on the base 1 from the side of the goods, which is also convenient to install. In addition, each panel is a decomposed module of the integral surrounding sleeve-shaped structure panel in the prior art, so that the weight of a single panel is also lighter, and it does not require multiple people to carry and install, thereby saving manpower and reducing costs.

[0053] In this embodiment, if Figure 1 、 Figure 2 、 Figure 3As shown, there are two enclosures 2A, both of which are C-shaped enclosures. The two enclosures 2A are connected around the base 1 through the first connecting fastener 4 and the second connecting fastener 5 to form a surrounding sleeve-like structure, which can surround the cargo. That is, each enclosure 2A includes: a first plate body 21, a second plate body 22 and a third plate body 23 that are connected in sequence and located on different sides of the enclosure box. The side of the first plate body 21 facing away from the second plate body 22 is connected to the first connecting fastener 4, and the side of the third plate body 23 facing away from the second plate body 22 is connected to the second connecting fastener 5. When the two enclosures 2A are installed on the base 1, the first plate body 21 on one enclosure 2A and the third plate body 23 on the other enclosure 2A are on the same side of the enclosure box, and the first connecting fastener 4 on one enclosure 2A is connected to the second connecting fastener 5 on the other enclosure 2A. In other embodiments, the first connecting fastener 4 can be on the third plate 23, and the second connecting fastener 5 can be on the first plate 21; alternatively, the first connecting fastener 4 can be connected to both the first plate 21 and the third plate 23 of one enclosure 2A, while the second connecting fastener 5 can be connected to both the first plate 21 and the third plate 23 of the other enclosure 2A. Furthermore, although both enclosures have a first plate 21, a second plate 22, and a third plate 23, the widths of the first plate 21 and the third plate 23 of the two enclosures can be different, as long as the two enclosures 2A on the same side of the enclosure box can be interlocked and connected by the first connecting fastener 4 and the second connecting fastener 5 to form the entire side panel of one side of the enclosure box. In actual use, the two enclosures 2A form the entire side wall of the enclosure box, and the two enclosures can have a 37-part, 55-part, 46-part, etc.

[0054] Further, if Figure 4-Figure 7 As shown, the first connecting fastener 4 has a plurality of first engaging portions 41 spaced apart along the height direction of the first free side, each having a first vertical portion 411 and a first horizontal portion 412. The second connecting fastener 5 has a plurality of second engaging portions 51 spaced apart along the height direction of the second free side, each having a second vertical portion 511 and a second horizontal portion 512. The first vertical portion 411 and the first horizontal portion 412 in two adjacent first engaging portions 41 respectively engage with the second vertical portion 511 and the second horizontal portion 512 in the same second engaging portion 51, and the first vertical portion is vertically engaged with the second vertical portion with which it is engaged, and the first horizontal portion 412 is horizontally engaged with the two horizontal portions with which it is engaged. This allows the connection between the two adjacent enclosures to be tighter, and also facilitates the engagement and connection between the second connecting fastener 5 and the first connecting fastener 4.

[0055] Further, if Figure 4-Figure 7As shown, the first connecting fastener 4 also has a first connecting body 42 connected to the first free side, and each first bite portion 41 is connected to the side of the first connecting body 42 facing away from the first free side. A long groove may be provided on the first connecting body 42, and the enclosure is inserted into the long groove so that the enclosure is snapped into the first connecting body 42. The first vertical portion 411 is a first slot with an upward opening, and the first horizontal portion 412 has a first slot 410. The first slot 410 is formed by at least partially bending and extending the first bite portion 41 to be separated from the side of the first connecting body 42 facing away from the first free side. In other embodiments, the opening of the first slot may also be downward. The first slot 410 has a first slot wall 413, and the first slot wall 413 is arranged opposite to the first free side. The second connecting fastener 5 also has a second connecting body 52 connected to the second free side, and each second bite portion 51 is connected to the side of the second connecting body 52 facing away from the second free side. The second connecting body 52 may be provided with a long slot, into which the enclosure is inserted, allowing the enclosure to be snapped into engagement with the second connecting body 52. The second horizontal portion 512 has a second slot 510, which is formed by at least partially bending and extending the second engaging portion 51 to be separated from the side of the second connecting body 52 that is away from the second free side. The second slot 510 has a second slot wall 513, which is arranged opposite to the second free side. The second vertical portion 511 may be a vertical plug plate that can be operably inserted into the corresponding first slot, the first slot wall 413 can be operably snapped into the second slot 510, and the second slot wall 513 can be operably snapped into the first slot 410.

[0056] In addition, if Figure 8 、 Figure 9 As shown, one of the first slot 410 and the second slot 510 opens toward the outside of the enclosure, and the other opens toward the inside of the enclosure. The slot wall of the first slot 410 connects the area between two adjacent second bite portions 51, and the slot wall of the second slot 510 connects the area between two adjacent first bite portions 41.

[0057] In addition, if Figure 5 、 Figure 9 As shown, the first vertical portion 411 is connected to the top of the first horizontal portion 412 , and the second vertical portion 511 is connected to the bottom of the second horizontal portion 512 .

[0058] In addition, if Figure 2 As shown, the base 1 has a slot 10 into which the enclosure is snapped.

[0059] The semi-enclosed plate can be operatively turned to the outside or inside of the enclosure box at a preset angle with its contact point with the base 1 as the center, so that the first connecting fastener 4 and the second connecting fastener 5 are disengaged or engaged. Specifically, Figure 8 、 Figure 9 、 Figure 10As shown, during installation, one enclosure is first installed on the base 1; then, when installing another enclosure, the bottom edge of the enclosure is inserted into the base 1, and the bottom edge of the second plate body 22 of the enclosure is rotated inwardly as the axis, while the first plate body 21 and the third plate body 23 are also rotated inwardly, and the second vertical portion 511 is inserted into the first slot, and the first horizontal portion 412 and the second horizontal portion 512 are hooked with each other, that is, the first groove wall 413 is snapped into the second slot 510, and the second groove wall 513 is snapped into the first slot 410, thereby connecting the two adjacent enclosures. When the lower panel needs to be removed, one panel can be lifted up, higher than the slot of the base 1 and tilted outward. The panel can be flipped outward 3°-6° with the corner P as the center, so that the first horizontal part 412 and the second horizontal part 512 engage and disengage. The bottom edge L of the second plate body 22 of the panel can be flipped outward about 10°-15° with the bottom edge L as the center, so that the first vertical part 411 and the second vertical part 511 engage and disengage. Through this first connecting fastener 4 and the second connecting fastener 5, it is not easy to disengage.

[0060] Another embodiment of the present invention provides a panel box 200. Compared with the above embodiment, the number of panels in the panel box 200 is different. Figure 11 、 Figure 12 As shown, the panel box 200 includes four panels, two of which are C-shaped panels 2C, and two of which are single-panel panels 2B. The two C-shaped panels 2C are arranged opposite each other, and the single-panel panel 2B is arranged between the two C-shaped panels 2C. The single-panel panel 2B has two second free sides located on the same side of the panel box, and the second connecting fastener 5 is connected to the second free sides. The two C-shaped panels 2C have two first free sides, and the first connecting fastener 4 is connected to the first free sides. The first connecting fastener 4 and the second connecting fastener 5 are connected.

[0061] It is understandable that in other embodiments, the single panel body 2B has a first free side and a second free side located on the same side of the enclosure box, the first connecting fastener 4 is connected to the first free side, the second connecting fastener 5 is connected to the second free side, and the first connecting fastener 4 or the second connecting fastener 5 is connected to the side of the C-shaped enclosure 2C that is opposite to the single panel body 2B. It is understandable that both sides of the single panel body 2B that are connected to other enclosures can also be the first free side or the second free side, as long as they can be engaged and connected with the adjacent enclosures. During installation, the two C-shaped enclosures 2C can be set relative to each other on the base 1 first, and then the single panel body 2B can be connected sequentially between the two C-shaped enclosures 2C. The height of the enclosure can be set according to actual conditions.

[0062] In other embodiments, the number of single-panel panels 2B may be 1 or greater than 2, and the number of C-shaped panels may be 1 or greater than two, and is not limited to the structure of the embodiment of the present application.

[0063] Further, if Figure 13 、 Figure 14 As shown, the panel box 200 also includes: a layer plate 7, which is detachably connected to a pair of side panels arranged opposite to the panel. The layer plate 7 can be one or more, and the layer plate 7 is detachably connected to the two C-shaped panel. During installation, the two C-shaped panel can be installed on the base 1 first, and then the layer plate 7 is installed, and finally the single panel body 2B is installed. It is understandable that in other embodiments, the layer plate 7 can also be detachably connected to the single panel body 2B. The arrangement of the layer plate 7 is not limited to the panel box structure of two C-shaped panel 2C and two single panel bodies 2B in this embodiment, and can also be the panel box in the first embodiment.

[0064] In addition, if Figure 15 、 Figure 16 、 Figure 17 As shown, a snap-in position 72 is provided on the side panel, and a plurality of snap-in members 71 snapping into the snap-in positions 72 are provided on both side walls of the layer panel 7. The snap-in members 71 on the two side walls of the layer panel 7 are staggered. Taking the figure as an example, three snap-in members 71 are provided on both side walls of the layer panel 7, but the snap-in members 71 on the two side walls are obliquely symmetrical, so that the height of the layer panels 7 can be reduced when they are stacked, and the snap-in members 71 of the upper and lower layer panels 7 will not be stacked together. The snap-in member 71 can be a hook, and the snap-in position 72 can be a notch, in which the hook is embedded. In other embodiments, the snap-in member 71 and the snap-in position 72 can also be other forms, as long as the layer panel 7 can be connected to the side panel of the enclosure box.

[0065] While preferred embodiments of the present invention have been described in detail above, it should be understood that aspects of the embodiments can be modified, if necessary, to employ aspects, features and concepts of the various patents, applications and publications to provide further embodiments.

[0066] These and other changes can be made to the embodiments in light of the above detailed description.In general, in the claims, the terms used should not be construed as limited to the specific embodiments disclosed in the specification and claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which these claims are entitled.

[0067] Those skilled in the art will appreciate that the above embodiments are specific embodiments for implementing the present invention, and that in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
