[0082] Embodiments of the present application are described below with reference to the accompanying drawings.

[0083] As shown in Figure 1 and Figure 2 , one embodiment of the present application provides a foldable container 10, which comprises a bottom plate 100, a pair of first side plates 200 and a pair of second side plates 300. The two first side plates 200 are hingedly connected to the bottom plate 100. The second side plates 300 are detachably connected to the bottom plate 100, and the first side plates 200 and the second side plates 300 are hingedly connected in sequence. The pair of first side plates 200 and the pair of second side plates 300 are operable to form a placement area around the bottom plate 100. The second side plates 300 comprise a first plate body 310 and a second plate body 320, and the first plate body 310 and the second plate body 320 are hingedly connected to the pair of first side plates 200 respectively. The first plate body 310 is foldably hingedly connected to the second plate body 320, and the hinging axes of the second side plates 300 and the first side plates 200 and the hinging axes of the first plate body 310 and the second plate body 320 are parallel to each other.

[0084] The bottom plate 100 has a pair of bottom part plates 110 hingedly connected, and the pair of bottom part plates 110 are hingedly connected to the bottoms of the pair of first side plates 200 respectively. The pair of bottom part plates 110 are operable to rotate around their hinging points, and each bottom part plate 110 is operable to rotate around its hinging point with the bottom of the first side plate 200. The hinging axes of the pair of bottom part plates 110 are parallel to the hinging axes of each bottom part plate 110 and the first side plate 200.

[0085] When the foldable container 10 needs to be folded, as shown in Figure 3 , the bottom plate 100 is separated from the second side plates 300, and the bottom plate 100 is moved towards the direction away from the placement area. Then the bottom part plates 110 rotate around the hinging points with the bottoms of the first side plates 200, and the two bottom part plates 110 rotate around their hinging points simultaneously. At the same time, the second side plates 300 are moved towards the direction of the placement area, and the first plate body 310 rotates around the hinging point with the first side plate 200, and the second plate body 320 rotates around the hinging point with the first side plate 200. The first plate body 310 and the second plate body 320 rotate around their hinging points simultaneously. The above movements stop when the bottom part plates 110, the first plate body 310 and the second plate body 320 can no longer rotate. At this time, the folding process of the foldable container 10 of the present embodiment ends, and a folding state diagram as shown in Figure 4 is formed. The above folding process can also be that the bottom plate 100 is moved towards the direction of the placement area, and the second side plates 300 are moved towards the direction away from the placement area.

[0086] The foldable container 10 of the embodiment of the present application can be folded and stacked for transportation when not containing any objects. When folded, the bottom plates 110 are hingedly connected to and rotate with the bottom of the first side plates 200, the two bottom plates 110 are hingedly connected to and rotate with each other, the first plate body 310 and the second plate body 320 are respectively hingedly connected to and rotate with the first side plates 200, and the first plate body 310 and the second plate body 320 are also hingedly connected to and rotate with each other. Therefore, the foldable container 10 of the present application will not be damaged after being folded multiple times, and can be used for a long time, thereby reducing costs and increasing efficiency. In addition, because it can be folded, the space occupied during transportation is small, the space utilization rate is high, and the transportation cost is low.

[0087] It should be understood that although the two first side plates 200 are hingedly connected to the bottom plate 100 in the embodiment, in other embodiments, the bottom plate 100 can also be provided to be hingedly connected to one first side plate 200 and detachably connected to the other first side plate 200. When folding is needed, only the end of the bottom plate 100 detachably connected to the first side plate 200 needs to be detached from the first side plate 200, and the end hingedly connected to the first side plate 200 is rotated and folded. The above-mentioned embodiments do not deviate from the scope of the present application. In the above-mentioned embodiments, the bottom plate 100 is provided as a pair of hingedly connected bottom plates 110, and those skilled in the art can also set the bottom plate 100 as a whole plate structure according to actual needs. At this time, the foldable container can be the structure in Figure 6 , and does not deviate from the scope of the present application.

[0088] Preferably, as shown in Figure 4 , when the pair of bottom plates 110 is operable to rotate along the hinge to the first position, the pair of bottom plates 110 is relatively attached, and the first position is the folding state in Figure 4 . This arrangement makes the structure of the bottom plate 100 of the folded foldable container 10 regular, and multiple folded foldable containers 10 can be stably stacked.

[0089] Further, as shown in Figure 4 and Figure 5 , the pair of bottom plates 110 are hingedly connected by the first double hinge structure 400, and when in the first position, the top of the pair of bottom plates 110 is located in the same horizontal plane, and the bottom of the pair of bottom plates 110 is located in the same horizontal plane. Those skilled in the art can make settings according to actual needs.

[0090] Preferably, the first double-hinge structure comprises a first hinged piece 410, a first hinged shaft 420, and a second hinged shaft 430 arranged in parallel with the first hinged shaft 420. The first hinged shaft 420 rotatably connects the first hinged piece 410 and one bottom panel 110, and the second hinged shaft 430 rotatably connects the first hinged piece 410 and the other bottom panel 110. The axis of the first hinged shaft 420 and the axis of the second hinged shaft 430 are parallel to the hinged axis of the bottom panel 110 and the first side panel 200. The first hinged piece 410 is rotatably connected to both bottom panels 110. In the first position, the first hinged piece 410 is located at the bottom of the two bottom panels 110. Since the top of the pair of bottom panels 110 is located at the same horizontal plane and the bottom of the pair of bottom panels 110 is located at the same horizontal plane, the first hinged piece 410 is also flat at this time, and the pair of bottom panels 110 can be completely attached after being folded. Those skilled in the art can make settings according to actual needs. In other embodiments, the top of the pair of bottom panels 110 can not be at the same horizontal plane, and the bottom of the pair of bottom panels 110 can also not be at the same horizontal plane.

[0091] In addition, each bottom panel 110 is operable to rotate around the hinged portion with the first side panel 200 towards the direction away from the placement area, and in the first position, the bottom panel 110 is located outside the pair of first side panels 200. This arrangement facilitates folding. Those skilled in the art can make settings according to actual needs.

[0092] Further, in the first position, the pair of bottom panels 110 are engaged by the first engagement structure 500. This arrangement can make the foldable container 10 form a stable structure after being folded and not easily deformed, and those skilled in the art can make settings according to actual needs.

[0093] Preferably, as shown in FIG. 1, the first double-hinge structure comprises a first hinged piece 410, a first hinged shaft 420, and a second hinged shaft 430 arranged in parallel with the first hinged shaft 420. The first hinged shaft 420 rotatably connects the first hinged piece 410 and one bottom panel 110, and the second hinged shaft 430 rotatably connects the first hinged piece 410 and the other bottom panel 110. The axis of the first hinged shaft 420 and the axis of the second hinged shaft 430 are parallel to the hinged axis of the bottom panel 110 and the first side panel 200. The first hinged piece 410 is rotatably connected to both bottom panels 110. In the first position, the first hinged piece 410 is located at the bottom of the two bottom panels 110. Since the top of the pair of bottom panels 110 is located at the same horizontal plane and the bottom of the pair of bottom panels 110 is located at the same horizontal plane, the first hinged piece 410 is also flat at this time, and the pair of bottom panels 110 can be completely attached after being folded. Those skilled in the art can make settings according to actual needs. In other embodiments, the top of the pair of bottom panels 110 can not be at the same horizontal plane, and the bottom of the pair of bottom panels 110 can also not be at the same horizontal plane. Figure 3 and Figure 4As shown, the first engaging structure 500 has a groove 510 formed on the side edge of the bottom panel 110, and a first engaging limiting member 520 protruding from the side edge of the bottom panel 110. The first engaging limiting member 520 on one bottom panel 110 is operable to be inserted into the groove 510 of another bottom panel 110. That is, when in the first position, the first engaging limiting member 520 on one bottom panel 110 is inserted into the groove 510 of another bottom panel 110. The bottom of the second side panel 300 has a second engaging limiting member 330, which is operable to engage with the first engaging limiting member 520. That is, when the foldable container 10 is unfolded for holding objects, the second engaging limiting member 330 on the bottom of the second side panel 300 engages with the first engaging limiting member 520 on the bottom panel 110, so that the second side panel 300 of the foldable container 10 is stably fixed with the bottom panel 110, and the structure of the foldable container 10 is stable when holding objects, so that the objects held in the foldable container 10 do not fall out. Those skilled in the art can make settings according to actual needs. Specifically, as shown in Figure 3 , the groove on the bottom of the second side panel has a protruding protruding member, forming the second engaging limiting member 330. The edge of the corresponding bottom panel 110 has a protruding block inserted into the groove, and the protruding block has a slot opening, forming the first engaging limiting member 520. The slot opening on the protruding block is used for the insertion of the protruding member to allow the bottom panel and the second side panel to engage.

[0094] In addition, as shown in Figure 6 and Figure 7 , the bottom panel 100 is an integral panel, and the bottom panel 100 is hingedly connected to the left first side panel 200 and detachably connected to the right first side panel 200 through the engaging structure. The bottom panel 100 is operable to rotate around the hinge between the bottom panel 100 and the left first side panel 200 towards or away from the direction of the placement area. When it is necessary to fold the foldable container 10, the bottom panel 100 is detached from the right first side panel 200, and then the bottom panel 100 is rotated around the hinge between the bottom panel 100 and the left first side panel 200 towards the direction of the placement area until it cannot be rotated any more, i.e., the bottom panel 100 is connected to the left first side panel 200. When it is necessary to change the foldable container 10 from the folded state to the state of holding objects, the bottom panel 100 is rotated around the hinge between the bottom panel 100 and the left first side panel 200 away from the direction of the placement area until the bottom panel 100 is connected to the right first side panel 200 through the engaging structure. It should be understood that although the bottom panel 100 is hingedly connected to the left first side panel 200 in the drawings, in another embodiment, the bottom panel 100 can also be hingedly connected to the right first side panel 200 and detachably connected to the left first side panel 200 through the engaging structure, without departing from the scope of the present application.

[0095] In addition, as shown in Figure 3 and Figure 8As shown, the first plate body 310 includes a first main door 311 detachably connected with the bottom plate 100, and a first movable door 312 movably connected with the side of the first main door 311 away from the bottom plate 100, and the first movable door 312 is operable to open or shield part of the placement area. When the light bubble goods such as the cigarette 20 are placed in the foldable container 10, when the cigarette 20 needs to be taken out, as shown in Figure 9 As shown, the first movable door 312 is opened, and the placement area is exposed, that is, the cigarette 20 can be taken out from the foldable container 10 without damaging the appearance of the cigarette 20, and after the cigarette 20 is taken out, the first movable door 312 can shield the placement area. Those skilled in the art can set it according to actual needs.

[0096] In addition, as shown in Figure 3 and Figure 8 As shown, the second plate body 320 includes a second main door 321 detachably connected with the bottom plate 100, and a second movable door 322 movably connected with the side of the second main door 321 away from the bottom plate 100, and the second movable door 322 is operable to open or shield part of the placement area. The structure of the second movable door 322 for opening and closing the placement area can be the same as that of the first movable door 312. Among them, the first main door 311 and the second main door 321 are hingedly connected, the first movable door 312 and the second movable door 322 are hingedly connected, and the hinging axes of the first movable door 312 and the second movable door 322 and the hinging axes of the first main door 311 and the second main door 321 are collinear. The folding process of the foldable container 10 is as shown in Figure 3 As shown, the first main door 311 and the second main door 321 are detached from the bottom plate 100, and then the first main door 311, the first movable door 312, the second main door 321 and the second movable door 322 are all folded towards the placement area, then the first main door 311 and the first movable door 312 move towards the placement area around the axis of the first side plate 200 adjacent to them, and the second main door 321 and the second movable door 322 move towards the placement area around the axis of the first side plate 200 adjacent to them, at the same time, the first main door 311 and the second main door 321, and the first movable door 312 and the second movable door 322 all rotate around the axis connected with them, and the above movement stops until the foldable container 10 is completely folded. And Figure 8 The process of taking out the cigarette 20 from the foldable container 10 is shown, the first movable door 312 and the second movable door 322 are opened, at this time the placement area is exposed, that is, the cigarette 20 can be taken out from the foldable container 10 without damaging the appearance of the cigarette 20, and after the cigarette 20 is taken out, the first movable door 312 and the second movable door 322 can shield the placement area. Those skilled in the art can set it according to actual needs. In some embodiments, the first movable door 312 and the second movable door 322 can have no hinging structure with the first side plate adjacent to them, as shown in Figure 6 and Figure 25.

[0097] The following illustrates the foldable container with three different second side plate structures:

[0098] Example 1

[0099] As Figure 1 shown in the figure, the first movable door 312 is hingedly connected with the adjacent first side plate 200, and the first movable door 312 is slidingly connected with its adjacent first side plate 200 and the first main door 311 relative to the direction of the bottom plate 100. That is, in the process of opening the first movable door 312, the first movable door 312 slides relative to its adjacent first side plate 200 and slides towards the direction of the bottom plate 100, while at the same time the first movable door 312 also slides relative to the first main door 311 and slides towards the direction of the bottom plate 100. Those skilled in the art can make settings according to actual needs. Specifically, as Figure 25 shown in the figure, a cross-sectional view of the hingedly connected part of the first movable door 312 and the adjacent first side plate 200 is shown. The first movable door 312 is connected with the adjacent first side plate 200 through a sixth hinge shaft 901, the first movable door 312 can rotate towards or away from the direction of the placement area around the sixth hinge shaft 901, and the sixth hinge shaft 901 penetrates the height direction of the first movable door 312. The first movable door 312 is arranged between the sixth hinge shaft 901 and the first side plate 200, and the length of the first movable door 312 surrounding the outside of the sixth hinge shaft 901 is shorter than the length of the sixth hinge shaft 901. Therefore, the first movable door 312 can not only rotate around the sixth hinge shaft 901, but also slide along the length direction of the sixth hinge shaft 901. The top end of the first side plate 200 is provided with a third protrusion 201 towards the direction of the sixth hinge shaft 901, and the third protrusion 201 surrounds the outside of the sixth hinge shaft 901 and is only provided with a small gap. Therefore, when the first movable door 312 slides upwards to abut against the third protrusion 201, it can stop sliding. Those skilled in the art can make settings according to actual needs.

[0100] Further, as Figure 1 shown in the figure, the first movable door 312 is provided with a first locking member 3121 for fixing it with the first main door 311. The first locking member 3121 is arranged to enable the first movable door 312 to be fixed with the first main door 311 so that the first movable door 312 cannot slide along the first main door 311 towards the direction of the bottom plate 100 at will, which cannot well protect the articles placed in the foldable container 10. Those skilled in the art can make settings according to actual needs.

[0101] Preferably, as Figure 9As shown, the first locking member 3121 is hingedly connected to the first movable door 312, and the top of the first main door 311 has a first abutting surface 313, and the top of the first main door 311 also has a first recessed area 220. The first locking member 3121 is operable to rotate about its hinged connection with the first movable door 312 to abut against the first abutting surface 313, and the first movable door 312 is positioned relative to the first main door 311. As shown, Figure 10 As shown, when it is necessary to take out the articles from the foldable container 10, the first locking member 3121 is operable to rotate about its hinged connection with the first movable door 312 to the first recessed area 220, and the first movable door 312 is movable relative to the first main door 311. Those skilled in the art can make settings according to actual needs.

[0102] As shown, Figure 1 In the embodiment, the second movable door 322 is hingedly connected to the adjacent first side plate 200, and the second movable door 322 is slidably connected to its adjacent first side plate 200 and the second main door 321 relative to the direction of the bottom plate 100. That is, in the process of opening the first movable door 312 and the second movable door 322, the first movable door 312 and the second movable door 322 are respectively slid relative to the adjacent first side plate 200 and towards the direction of the bottom plate 100, while the first movable door 312 is also slid relative to the first main door 311 and towards the direction of the bottom plate 100, and the second movable door 322 is also slid relative to the second main door 321 and towards the direction of the bottom plate 100. Those skilled in the art can make settings according to actual needs. The hinged structure of the second movable door 322 and the adjacent first side plate 200 can be similar to the hinged structure of the first movable door 312 and the adjacent first side plate 200, which will not be described in detail again. In Figure 1 In order to position the second movable door 322 when shielding the placement area, the second movable door 322 is provided with a second locking member 3222 for fixing the second movable door 322 to the second main door 321. The second locking member 3222 is arranged to enable the second movable door 322 to be fixed to the second main door 321 so that the second movable door 322 cannot slide along the second main door 321 towards the direction of the bottom plate 100, and the articles contained in the foldable container 10 cannot be well protected, and those skilled in the art can make settings according to actual needs.

[0103] Preferably, Figure 15 is a sectional view of the part of the second locking member 3222 abutting against the second main door 321, in combination with Figure 14As shown, the second locking member 3222 is hinged to the second movable door 322, and the top of the second main door 321 has a second abutting surface 323, and the top of the second main door 321 also has a second recessed area 324. When the second locking member 3222 is rotated around the hinge between the second locking member 3222 and the second movable door 322 to abut against the second abutting surface 323, the second movable door 322 is positioned relative to the second main door 321, and when the second locking member 3222 is rotated around the hinge between the second locking member 3222 and the second movable door 322 to the second recessed area 324, the second movable door 322 is movable relative to the second main door 321. Those skilled in the art can make settings according to actual needs.

[0104] The folding process of the foldable container 10 is as follows Figure 3 As shown, the first main door 311 and the second main door 321 are detached from the bottom plate 100, and then the first main door 311, the first movable door 312, the second main door 321 and the second movable door 322 are all folded towards the placement area. At this time, the first main door 311 and the first movable door 312 move towards the placement area around the axis of the first side plate 200 adjacent to them, and the second main door 321 and the second movable door 322 move towards the placement area around the axis of the first side plate 200 adjacent to them. At the same time, the first main door 311 and the second main door 321 rotate around the axis connecting them, and the first movable door 312 and the second movable door 322 rotate around the axis connecting them. The above movements stop until the foldable container 10 is completely folded.

[0105] Example 2

[0106] As shown in Figure 6 and Figure 11 The structure of the first movable door 312 in this embodiment is different from that in Figure 1 In FIG. 6 and Figure 11 The first movable door 312 is folded in connection with the first main door 311 towards or away from the placement area. In order to allow the first movable door 312 to shield the placement area, that is, to be in the closed state, the first movable door 312 is folded in connection with the first main door 311 towards the placement area, and the first movable door 312 is folded in connection with the first main door 311 away from the placement area when the first movable door 312 is in the open state. Figure 6When the first movable door 312 is in the state of covering the placing area, the first movable door 312 can be connected with its adjacent first side plate 200 by a latch, which can be installed on the first movable door 312. When the first movable door 312 and its adjacent first side plate 200 need to be locked, the latch is inserted into the first side plate 200. When the first movable door 312 needs to be flipped outwardly and downwardly, the latch can be pulled to the right to separate the latch from the first side plate 200. It can be understood that in some embodiments, the latch can not be provided, but other locking members can be provided to position the first movable door 312 and its adjacent first side plate 200, and to facilitate the free movement of the first movable door 312 relative to its adjacent first side plate 200. In addition, if the latch or other locking members that position the first movable door 312 and its adjacent first side plate 200 are not provided, when the first movable door 312 covers the placing area, the first movable door 312 and its adjacent first side plate 200 can be abutted to maintain the first movable door 312 from being easily folded outwardly and downwardly. When the cigarette 20 needs to be taken out, the first movable door 312 is separated from its adjacent first side plate 200, and then is folded in a direction away from the placing area, and the placing area is exposed, so that the cigarette 20 can be taken out without damaging the shape of the cigarette 20. When the placing area needs to be closed, the first movable door 312 is folded in a direction toward the placing area until the first movable door 312 is connected with its adjacent first side plate 200. Specifically, when the first movable door 312 is vertical, i.e., the first movable door 312 closes the placing area, the side wall of the first movable door 312 toward the placing area side is close to the edge of the first side plate 200 toward the first movable door 312. In other embodiments, a snap structure can be provided to detachably connect the first movable door 312 and its adjacent first side plate 200, for example, a protrusion is provided on the first movable door 312, and a recess is provided on the first side plate 200. When the first movable door 312 closes the placing area, the protrusion and the recess are arranged opposite to each other to snap together to connect the first movable door 312 and the first side plate 200. Those skilled in the art can make settings according to actual needs.

[0107] In addition, as shown in Figure 6 and Figure 11 shown in relation to Figure 3The second side plate 300 is different from the first side plate 200 in structure. The first movable door 312 is foldably connected to the first main door 311 in a direction towards or away from the placement area. The second movable door 322 is foldably connected to the second main door 321 in a direction towards or away from the placement area. When it is needed to take out the cigarette 20, the first movable door 312 and the second movable door 322 are respectively detached from the first side plate 200 adjacent thereto, and then are folded in a direction away from the placement area, so that the placement area is exposed, and then the cigarette 20 can be taken out without damaging the shape of the cigarette 20. When it is needed to close the placement area, the first movable door 312 and the second movable door 322 are folded in a direction towards the placement area until the first movable door 312 and the second movable door 322 are respectively connected to the first side plate 200 adjacent thereto. Specifically, when the first movable door 312 is vertical, i.e. the first movable door 312 closes the placement area, the side wall of the first movable door 312 towards the placement area is tightly attached to the edge of the first side plate 200 towards the first movable door 312. Similarly, when the second movable door 322 is vertical, i.e. the second movable door 322 closes the placement area, the side wall of the second movable door 322 towards the placement area is tightly attached to the edge of the first side plate 200 towards the second movable door 322.

[0108] In addition, in order to position the second movable door 322 and the first side plate 200 adjacent thereto, the second movable door 322 and the first side plate 200 adjacent thereto can be connected by a latch. The latch can be installed on the second movable door 322. When the second movable door 322 and the first side plate 200 adjacent thereto need to be locked, the latch is inserted into the first side plate 200. When it is needed to turn the second movable door 322 outward and downward, the latch can be pulled to the right to separate the latch from the first side plate 200. It can be understood that in some embodiments, the latch can not be provided, but other locking members can be provided to position the second movable door 322 and the first side plate 200 adjacent thereto, and to facilitate the free movement of the second movable door 322 relative to the first side plate 200 adjacent thereto. In addition, if the latch or other locking members for positioning the second movable door 322 and the first side plate 200 adjacent thereto are not provided, when the second movable door 322 blocks the placement area, the second movable door 322 and the first side plate 200 adjacent thereto can be abutted to maintain the second movable door 322 from being folded outward and downward. In other embodiments, a clamping structure can be provided to detachably connect the second movable door 322 and the first side plate 200 adjacent thereto. For example, a protrusion is provided on the second movable door 322, and a recess is provided on the first side plate 200. When the second movable door 322 closes the placement area, the protrusion and the recess are oppositely arranged to be clamped to connect the second movable door 322 and the first side plate 200 together. Those skilled in the art can make settings according to actual needs.

[0109] Preferably, the first movable door 312 is connected with the first main door 311 through the second hinge structure 500, the second movable door 322 is connected with the second main door 321 through the second hinge structure 500, and the hinge axis of the second hinge structure 500 is perpendicular to the hinge axis of the second side plate 300 relative to the first side plate 200. Those skilled in the art can make settings according to actual needs.

[0110] Further, as shown in Figure 13 , the second hinge structure 500 has two third hinge axes 510 parallel to each other. As shown in FIG. 11, the two third hinge axes 510 parallel to each other can ensure that the first movable door 312 and the second movable door 322 can be respectively attached to the first main door 311 and the second main door 321 after rotating around the hinge axis of the second hinge structure 500. Those skilled in the art can make settings according to actual needs.

[0111] In addition, Figure 16 , a cross-sectional view of the third hinge structure 600 is shown, in combination with Figure 3 , the first main door 311 and the second main door 321 are connected through the third hinge structure 600. Figure 17 , a cross-sectional view of the fourth hinge structure 700 is shown, in combination with Figure 12 , the first movable door 312 and the second movable door 322 are connected through the fourth hinge structure 700. Those skilled in the art can make settings according to actual needs. Specifically, the third hinge structure 600 has a hinge axis connecting the first main door 311 and the second main door 321, the hinge axis penetrates the top end and the bottom of the connecting side of the first main door 311 and the second main door 321, so that the first main door 311 and the second main door 321 are both connected with the hinge axis. The third hinge structure 600 is similar to the fourth hinge structure 700, and will not be repeated here.

[0112] Example 3

[0113] As Figure 22 and Figure 23Another second side panel structure is shown, in which the first main door 311 has a first frame plate 315 extending partially away from the bottom plate 100, and the first frame plate 315 is adjacent to the first side panel 200 adjacent to the first main door 311. The first movable door 312 is engaged with the first frame plate 315, and the first movable door and the first main door 311 are folded together in a direction facing away from the placement area. Specifically, the first frame plate 315 has a first groove on the side facing away from the placement area, and this first groove opens in a direction facing away from the first side panel 200. The first movable door has a first protrusion 316 on the side facing away from the placement area, and the first protrusion 316 protrudes towards the first frame plate 315. The first groove and the first protrusion 316 are correspondingly arranged. When it is necessary to cover the placement area, the first protrusion 316 is inserted into the first groove, and then the first movable door 312 is connected to the first frame plate 315, that is, the first movable door 312 is connected to the first main door 311. When the placement area needs to be opened, the operation is the reverse of the above steps. It should be understood that the first groove can also be positioned on the side of the first frame plate 315 facing the placement area, and the first protrusion 316 can also be correspondingly positioned on the side facing the placement area, with the first groove and the first protrusion 316 corresponding to each other. This configuration can also connect the first movable door 312 to the first main door 311 without departing from the scope of the invention. Those skilled in the art can make the configuration according to actual needs. The first frame plate 315 and its adjacent first side plate can be hinged together or not. When the first frame plate 315 and its adjacent first side plate are hinged together, the hinge structure can be the same as the hinge structure between the first main plate 311 and its adjacent first side plate, and can be connected by the same connecting shaft passing through the first frame plate 315, the first main plate 311, and its adjacent first side plate.

[0114] Preferably, such as Figure 23 As shown, the first movable door 312 is connected to the first frame plate 315 via a first locking pin 317. Specifically, a third recessed area 318 is provided on the side of the first movable door 312 away from the placement area, and the first frame plate 315 has a slot for inserting the locking tongue of the first locking pin 317 on the side facing the first movable door 312. When the first movable door 312 is connected to the first frame plate 315, it can be opened as follows: Figure 23 Pushing the first locking pin 317 to the left from the center pushes the locking tongue of the first locking pin 317 into the first frame plate 315, thus locking the first movable door 312 to the first frame plate 315. The first locking pin 317 is engaged in the third recessed area 318. This structure connects the first frame plate 315 and the first movable door 312 together. When it is necessary to bend the first movable door 312 outward, Figure 23The first lock pin 317 is pulled to the right to make the locking tongue of the first lock pin 317 leave the socket of the first frame plate 315, i.e. to unlock the first movable door 312 and the first frame plate 315, and then the first movable door 312 is folded outward and downward. It should be understood that those skilled in the art can also connect the first movable door 312 and the first frame plate 315 in other ways, such as through hinging or other ways, without departing from the scope of the present application, and those skilled in the art can set them according to actual needs.

[0115] In addition, as shown in Figure 22 and Figure 24 , the second main door 321 has a second frame plate 325 extending partially away from the bottom plate 100, and the second frame plate 325 is adjacent to the first side plate 200 adjacent to the second main door 321. Among them, the second movable door 322 is connected with the second frame plate 325, and the second movable door 322 is folded with the second main door 321 in the direction away from the placement area. Specifically, a second recess is provided on the side of the second frame plate 325 away from the placement area, and the second recess is open in the direction away from the first side plate 200, and the side of the second movable door 322 away from the placement area is provided with a second protrusion 326, the second protrusion 326 protrudes in the direction of the second frame plate 325, the second recess and the second protrusion 326 are correspondingly arranged, when it is needed to shield the placement area, the second protrusion 326 is clamped into the second recess, then the second movable door 322 is connected with the second frame plate 325, i.e. the second movable door 322 is connected with the second main door 321. When it is needed to open the placement area, i.e. the second protrusion 326 is taken out of the second recess, and then the second movable door 322 is folded in the direction away from the placement area. It should be understood that the second recess described above can also be arranged on the side of the second frame plate 325 facing the placement area, and the second protrusion 326 is correspondingly arranged on the side facing the placement area, and the second recess and the second protrusion 326 are correspondingly arranged, which can also realize the connection between the second movable door 322 and the second main door 321, without departing from the scope of the present application, and those skilled in the art can set them according to actual needs. Among them, the second frame plate 325 and the first side plate 200 adjacent thereto can be hingedly connected, or can not be connected. When the second frame plate 325 and the first side plate 200 adjacent thereto are hingedly connected, the hinge structure can be the same as the hinge structure between the second main plate 321 and the first side plate 200 adjacent thereto, and can pass through the second frame plate 325 and the second main plate 321 and the first side plate 200 adjacent thereto through the same connecting shaft.

[0116] Preferably, as shown in Figure 24As shown, the second movable door 322 is connected with the second frame plate 325 through the second lock pin 327. Specifically, a fourth recessed area 328 is arranged on the side of the second movable door 322 away from the placing area, and the side of the second frame plate 325 facing the second movable door 322 is provided with an insertion opening for the insertion of the lock tongue of the second lock pin 327. When the second lock pin 327 is connected with the second frame plate 325, the second movable door 322 can be connected with the second frame plate 325 by Figure 24 pushing the second lock pin 327 to the right, pushing the lock tongue of the second lock pin 327 into the second frame plate 325, locking the second movable door 322 with the second frame plate 325, and clamping the second lock pin 327 in the fourth recessed area 328. In this way, the second frame plate 325 and the second movable door 322 can be connected together. When it is needed to bend the second movable door 322 outwardly, the second lock pin 327 is pulled to the left, so that the lock tongue of the second lock pin 327 is separated from the insertion opening of the second frame plate 325, i.e. the second movable door 322 and the second frame plate 325 are unlocked, and then the second movable door 322 is bent outwardly and downwardly. It should be understood that the second movable door 322 and the second frame plate 325 can also be connected in other ways by those skilled in the art, for example, they can be connected by hinging or other ways, which do not deviate from the scope of the present application, and those skilled in the art can set them according to actual needs.
