Technical Field

[0001] The invention relates to the technical field of construction site storage boxes, and more particularly to a foldable storage cabinet. Background Art

[0002] Site storage boxes are commonly used on construction sites and are often used to store a variety of tools, hardware and equipment. Existing boxes are usually supported by heavy steel and cannot be folded, which makes the transportation volume larger and increases the transportation cost. Summary of the invention

[0003] The present invention overcomes the problem in the prior art that the construction site storage box cannot be folded, which increases the transportation cost, and provides a foldable storage cabinet, which can fold the construction site storage box during transportation, thereby reducing the transportation cost.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a folding storage cabinet, comprising: a bottom wall and a top wall, the bottom wall being hinged with a first side wall and a second side wall; two first side walls and two second side walls are each provided, and are relatively arranged on both sides of the bottom wall; the second side wall is hinged to the top wall, and the second side wall comprises a plurality of side wall panels hinged to each other; when in a folded state, the plurality of side wall panels are folded, and the first side wall and the second side wall are folded around the hinged edge with the bottom wall and stored between the top wall and the bottom wall.

[0005] When the present application needs to be transported, the first side wall and the second side wall can be folded toward the bottom wall so that the whole is in a folded state, and the overall volume after folding is small, thereby reducing the space occupied by the transportation of a single product and further reducing the transportation cost; and when it needs to be unfolded, the top wall is directly pulled up so that the second side wall is in a vertical state, and then the first side wall is unfolded to make it in a vertical state, and the first side wall and the second side wall are fixedly connected by a connecting piece, thereby completing the assembly of the overall structure, which has the characteristic of easy assembly.

[0006] Preferably, the hinged edge of the first side wall and the bottom wall is the first edge, the hinged edge of the second side wall and the bottom wall is the second edge, the vertical height of the first edge from the bottom wall is H1, the vertical height of the second edge from the bottom wall is H2, the thickness of the first side wall is D, H2-H1≧D.

[0007] H2-H1≧D, so that when in a folded state, when the first side wall and the bottom wall are in contact, the first side wall can be located below H2 after folding, that is, the first side wall can be located below the second side, without affecting the folding of the second side wall, so that the overall volume is smaller after folding.

[0008] Preferably, a plurality of seat covers and a plurality of detachable rollers are provided at the bottom of the bottom wall, and the seat covers are arranged on both sides along the width direction of the bottom wall.

[0009] The seat cover is arranged along both sides of the bottom wall in the width direction, so that the two clamping arms on the forklift can pass through the seat cover on both sides in the width direction respectively, so that the center of gravity can fall between the two clamping arms of the forklift during transportation, thereby improving the stability of the transportation folding locker. Removable rollers are arranged on the bottom wall, and the rollers can be removed during transportation and placed in the seat cover or between the bottom wall and the top wall, thereby reducing the overall volume.

[0010] Preferably, the seat cover comprises a first plate, a second plate and a third plate are respectively arranged at two ends of the first plate, and the roller is detachably arranged at the bottom of the first plate.

[0011] The roller is arranged at the bottom of the first plate, so that the height of the bottom wall is the sum of the height of the roller and the height of the seat cover, thereby increasing the overall height of the folding locker chassis. Since the environment of the construction site is harsh and the ground is often uneven, the roller is arranged at the bottom of the first plate to increase the height of the folding locker chassis, thereby improving the traffic capacity of the folding locker on the construction site.

[0012] Preferably, the first plate is arranged on a side close to the width direction of the bottom wall, and the first plate is inclined toward the side close to the bottom wall.

[0013] The seat covers are arranged on both sides of the bottom wall in the width direction, so that the first plates on the seat covers on both sides in the width direction form a structure similar to an "eight-shaped" shape on both sides of the bottom wall, so that the seat covers on the bottom wall play a stable supporting role for the folding storage cabinet and also improve the overall strength of the side walls.

[0014] Preferably, the top wall includes an upper fixing frame and an upper cover; a side edge of one side of the upper cover is hinged to the fixing frame.

[0015] The upper cover can be rotated around the upper cover hinge edge, so that the foldable storage cabinet can be opened and closed when needed.

[0016] Preferably, a support rod is provided between the upper fixing frame and the upper cover, one end of the support rod is connected to the upper fixing frame, and the other end of the support rod is connected to the upper cover.

[0017] The support rod includes but is not limited to a hydraulic buffer rod. One end of the hydraulic buffer rod is connected to the inner wall of the upper fixed frame, and the other end of the hydraulic buffer rod is connected to the upper cover. When the upper cover is opened, due to the heavy weight of the upper cover, the upper cover may be suddenly closed due to the effect of gravity during operation, and the worker's hand may be clamped, which may cause danger. Therefore, a hydraulic buffer rod is provided. When the upper cover is closed, the hydraulic buffer rod can play a buffering role on the upper cover, so that the upper cover can be closed slowly, thereby preventing the above-mentioned danger from occurring.

[0018] Preferably, the side wall of the upper fixed frame is provided with an inwardly recessed lock groove, the upper end of the lock groove is provided with a lock plate, a lock hole is penetrated through the lock plate, and the upper cover is provided with a lock rod cooperating with the lock hole.

[0019] When the upper cover is closed, the locking rod can just pass through the locking hole. A locking rod through hole is arranged at the end of the locking rod. The upper cover and the upper fixing frame can be locked by connecting the lock and the locking rod through hole.

[0020] Preferably, the first side wall is provided with an inwardly recessed side wall portion, and a handle is rotatably provided in the side wall recess.

[0021] The handle is arranged to facilitate pushing and pulling the folding storage cabinet.

[0022] Preferably, the side wall recess is provided with rotating shafts at both ends along the width direction of the first side wall, and both ends of the handle are rotatably connected to the rotating shafts at both ends.

[0023] When the handle is affected by gravity, it can be in a vertical state, and the handle is stored in the recessed portion of the side wall without protruding from the end surface of the first side wall, which also makes the overall volume smaller after folding.

[0024] Compared with the prior art, the present invention has the following beneficial effects: (1) In the present invention, when transportation is required, the first side wall and the second side wall can be folded toward the bottom wall so that the whole is in a folded state, and the overall volume after folding is small, thereby reducing the space occupied by a single product for transportation, thereby reducing the transportation cost; (2) When it is necessary to unfold, the top wall is directly pulled up to make the second side wall in a vertical state, and then the first side wall is unfolded to make it in a vertical state, and the first side wall and the second side wall are fixedly connected by a connecting piece to complete the assembly of the overall structure, which has the characteristic of easy assembly; (3) The second side wall is formed by hingedly connecting a plurality of side wall panels, so that when folded, the two side wall panels can be folded together, so that the volume after folding can be smaller; (4) A detachable roller is provided on the bottom wall. When transporting, the roller can be removed and placed in the seat cover or between the bottom wall and the top wall, thereby reducing the overall volume and the transportation cost; (5) The side wall of the upper fixing frame is provided with an inwardly recessed locking groove, thereby reducing the volume after folding and further reducing the transportation cost; (6) When the handle is subjected to gravity, it can be in a vertical state, and the handle is stored in the side wall recess, does not protrude from the end surface of the first side wall, and in the folded state, the handle can be retracted in the side wall recess, reducing the overall volume after folding; (7) The seat cover can facilitate, for example, the clamp arm of a forklift to pass through the seat cover, thereby eliminating the trouble of using a forklift bracket during the transportation of the folding locker, thereby improving the efficiency of transporting the folding locker; (8) The rollers are arranged at the bottom of the first plate, which can increase the height of the chassis of the folding locker, thereby improving the traffic capacity of the folding locker on the construction site.

[0038] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Example 1: Reference Figures 1 to 10 As shown, a foldable storage cabinet includes: a bottom wall 1 and a top wall 2, the bottom wall 1 is hinged with a first side wall 3 and a second side wall 4; two first side walls 3 and two second side walls 4 are each provided, and are relatively arranged on both sides of the bottom wall 1; the second side wall 4 is hinged to the top wall 2, and the second side wall 4 includes a plurality of side wall single plates 41 hinged to each other; in the folded state, the plurality of side wall single plates 41 are folded, and the first side wall 3 and the second side wall 4 are folded around the hinged edges with the bottom wall 1 and stored between the top wall 2 and the bottom wall 1.

[0039] In this embodiment, the bottom wall 1 and the first side wall 3, the second side wall 4 and the top wall 2 around it together form a box body, forming a storage space inside, and the first side wall 3 and the second side wall 4 are both hinged to the bottom wall 1, so that the first side wall 3 and the second side wall 4 can be rotated around the side of the bottom wall 1 respectively, so that when folded, the first side wall 3 and the second side wall 4 can be folded towards the bottom wall 1 (such as Figure 1As shown by the arrow in the middle). The second side walls 4 arranged opposite to each other do not interfere with each other in the folded state, which affects the folding effect. At the same time, the second side walls 4 can have a certain height in the unfolded state, thereby increasing the usable volume of the box. Therefore, the second side wall 4 is configured as a plurality of side wall single plates 41 hinged to each other, so that in the unfolded state, the side wall single plates 41 can be unfolded to form a first side wall 3 with a higher height, thereby increasing the usable volume of the cavity. At the same time, when folding, the plurality of side wall single plates 41 can be folded with each other, so that the overall width of the folded second side wall 4 is only the width of a single side wall single plate 41, and the two folded second side walls 4 can be distributed on both sides of the bottom wall 1, so that the overall will not interfere with each other after folding.

[0040] When it is needed to be used, the folded box body needs to be unfolded. Since the top wall 2 and the second side wall 4 are hinged, the top wall 2 can be directly pulled up when unfolding, so that the second side wall 4 can be in a vertical state perpendicular to the bottom wall 1, and then the first side wall 3 is unfolded, so that the first side wall 3 is in a vertical state perpendicular to the bottom wall 1, and then the contact part of the first side wall 3 and the second side wall 4 is fixed by a connecting piece to complete the assembly of the box body.

[0041] Therefore, in this embodiment, when transportation is required, the first side wall 3 and the second side wall 4 can be folded toward the bottom wall 1 so that the whole is in a folded state, and the overall volume after folding is small, thereby reducing the space occupied by the transportation of a single product and thus reducing the transportation cost; and when unfolding is required, the top wall 2 is directly pulled up so that the second side wall 4 is in a vertical state, and then the first side wall 3 is unfolded to make it in a vertical state, and the first side wall 3 and the second side wall 4 are fixedly connected by connecting parts, thereby completing the assembly of the overall structure, which has the characteristic of easy assembly.

[0042] Example 2: Reference Figures 1 to 10 As shown, a foldable storage cabinet includes: a bottom wall 1 and a top wall 2, the bottom wall 1 is hinged with a first side wall 3 and a second side wall 4; two first side walls 3 and two second side walls 4 are each provided, and are relatively arranged on both sides of the bottom wall 1; the second side wall 4 is hinged to the top wall 2, and the second side wall 4 includes a plurality of side wall single plates 41 hinged to each other; in the folded state, the plurality of side wall single plates 41 are folded, and the first side wall 3 and the second side wall 4 are folded around the hinged edges with the bottom wall 1 and stored between the top wall 2 and the bottom wall 1.

[0043] The first side walls 3 are arranged at both ends of the bottom wall 1 in the length direction, and the second side walls 4 are arranged at both ends of the bottom wall 1 in the width direction. The horizontal length of the first side wall 3 is shorter than the horizontal length of the second side wall 4 .

[0044] The hinged edge of the first side wall 3 and the bottom wall 1 is defined as the first edge, the hinged edge of the second side wall 4 and the bottom wall 1 is defined as the second edge, the vertical height of the first edge from the bottom wall 1 is H1, the vertical height of the second edge from the bottom wall 1 is H2, H2 is greater than H1, the thickness of the first side wall 3 is D, H2-H1≧D. Through the above arrangement, when in the folded state, when the first side wall 3 and the bottom wall 1 are attached, the first side wall 3 can be located below H2 after folding, that is, the first side wall 3 can be located below the second edge, without affecting the folding of the second side wall 4, so that the overall volume is smaller after folding.

[0045] In addition, if Figure 3 As shown, the first side wall 3 in this embodiment is an integral plate structure, so in the folded state, after the first side wall 3 is attached to the bottom wall 1, in order to prevent the two folded first side walls 3 from interfering with each other, the height of the first side wall 3 is H3, the length of the bottom wall 1 is L, and 2*H3≦L. Therefore, when the first side wall 3 is folded, the two first side walls 3 can be attached to both sides of the bottom wall 1 in the length direction.

[0046] It should be noted that in order to enable the second side wall 4 to be folded, a plurality of side wall panels 41 can be folded together. In this embodiment, the second side wall 4 is formed by two side wall panels 41 being hinged to each other, so that when folded, the two side wall baffles can be folded together. Of course, the side wall panels 41 can also be set to three (such as Fig.10 As shown), 4 and other numbers.

[0047] The first side wall 3 is configured as a plurality of side wall panels 41 hinged to each other, so that in the box state, the side wall panels 41 can be unfolded to form a first side wall 3 with a relatively high height, thereby ensuring the usable volume of the folding storage cabinet in the unfolded state. At the same time, when folding, the plurality of side wall panels 41 can be overlapped with each other, so that the overall width of the folded second side wall 4 is only the width of a single side wall panel 41, thereby allowing the two folded first side walls 3 to be distributed on both sides of the bottom wall 1, so that the two second side walls 4 will not interfere with each other in the folded state.

[0048] In order to facilitate the movement of the folding locker during use, it is more convenient to move the folding locker with equipment such as forklifts and clamping machines. Figure 2 As shown, a plurality of seat covers 5 and detachable rollers 6 are arranged at the bottom of the bottom wall 1 , and the seat covers 5 are arranged along both sides of the width direction of the bottom wall 1 .

[0049] In this embodiment, four seat covers 5 and four rollers 6 are respectively provided. Therefore, on both sides of the bottom wall 1 in the width direction, two seat covers 5 and two rollers 6 are provided on each side.

[0050] The arrangement of the seat cover 5 can facilitate the forklift's clamping arm to pass through the seat cover 5, thereby eliminating the trouble of using a forklift bracket in the process of transporting the folding locker, thereby improving the efficiency of transporting the folding locker. In addition, the seat cover 5 can also support the folding locker. Therefore, in order to improve the stability of the forklift transporting the folding locker, the seat cover 5 is arranged along both sides of the width direction of the bottom wall 1, so that the two clamping arms on the forklift can respectively pass through the seat cover 5 on both sides in the width direction, so that during transport, the center of gravity can fall between the two clamping arms of the forklift, thereby improving the stability of the transporting folding locker.

[0051] The bottom wall 1 is provided with a detachable roller 6, which can be removed during transportation and placed in the seat cover 5 (such as Figure 7 as shown) or between the bottom wall 1 and the top wall 2 (as shown Figure 8 as shown) or between the side wall baffle 41 and the top wall 2 (as shown Fig. 9 As shown in the figure, the overall volume is reduced; and when in use, it can be installed on the bottom wall 1, which is convenient for pushing the folding locker to move when in use. A roller stopper 61 can also be provided on the roller 6, which can lock the roller 6 at any time as needed when in use, thereby preventing the box from moving.

[0052] In one embodiment, the seat cover 5 includes a first plate 51, and the two ends of the first plate 51 are respectively provided with a second plate 52 and a third plate 53, and the roller 6 is detachably arranged at the bottom of the first plate 51. A mounting plate 62 is arranged on the top of the roller 6, and the mounting plate 62 and the first plate 51 are fixedly connected by bolts, so that the roller 6 can be detachably connected to the first plate 51. The roller 6 can be directly connected to the bottom of the bottom wall 1 like the seat cover 5, and in this embodiment, the roller 6 is arranged at the bottom of the first plate 51, which makes the height of the bottom wall 1 the sum of the height of the roller 6 and the height of the seat cover 5, thereby increasing the overall height of the chassis of the folding locker. Due to the harsh environment of the construction site and the uneven ground in most cases, the height of the chassis of the folding locker can be increased by arranging the roller 6 at the bottom of the first plate 51, thereby improving the traffic capacity of the folding locker on the construction site.

[0053] In order to improve the stability of the overall structure, the first plate 51 is arranged on the side close to the width direction of the bottom wall 1, and the first plate 51 is inclined toward the side close to the bottom wall 1 (such as Figure 2 As shown). Since the seat cover 5 is arranged on both sides of the bottom wall 1 in the width direction, the first plates 51 on the seat cover 5 on both sides in the width direction form a structure similar to an "eight-shaped" structure on both sides of the bottom wall 1, so that the seat cover 5 on the bottom wall 1 plays a stable supporting role for the folding storage cabinet and also improves the overall strength of the side wall.

[0054] In one embodiment, the structures of the top wall 2 and the bottom wall 1 are similar. The bottom wall 1 includes a lower fixing frame 11 and a lower cover 12, and the lower cover 12 is fixedly connected to the lower fixing frame 11. The top wall 2 includes an upper fixing frame 21 and an upper cover 22, and the side edge of one side of the upper cover 22 is hinged to the side edge of one side of the upper fixing frame 21, and the side wall where the upper cover 22 and the upper fixing frame 21 are hinged is the upper cover hinge edge, so that the upper cover 22 can rotate around the upper cover hinge edge, so that the folding storage cabinet can be opened and closed when needed.

[0055] The lower fixed frame 11 includes two first wide strips 111 and two first long strips 112. The two first wide strips 111 are arranged opposite to each other, and the two first long strips 112 are arranged opposite to each other. The first wide strip 111 is hinged to the first side wall 3, and the first long strip 112 is hinged to the second side wall 4. The height of the first long strip 112 is higher than the height of the first wide strip 111. When the first side wall 3 and the bottom wall 1 are in a folded state, the upper end surface of the first side edge is lower than the upper end surface of the first long strip 112, and the folding of the second side wall 4 is not affected.

[0056] The upper fixing frame 21 includes two second wide strips 211 and two second long strips 212. The two second wide strips 211 are arranged opposite to each other, and the two second long strips 212 are also arranged opposite to each other. The two second long strips 212 are respectively hinged to the top ends of the two second side walls 4. The height of the second long strips 212 is higher than that of the second wide strips 211.

[0057] A support rod is provided between the upper fixed frame 21 and the upper cover 22, and the support rod includes but is not limited to a hydraulic buffer rod 13. One end of the hydraulic buffer rod 13 is connected to the inner wall of the upper fixed frame 21, and the other end of the hydraulic buffer rod 13 is connected to the upper cover 22. When the upper cover 22 is opened, due to the heavy weight of the upper cover 22, the upper cover 22 may be suddenly closed due to the effect of gravity during operation, and the worker's hand may be clamped, causing danger. Therefore, a hydraulic buffer rod 13 is provided, and when the upper cover 22 is closed, the hydraulic buffer rod 13 can play a buffering role on the upper cover 22, so that the upper cover 22 can be closed slowly, thereby preventing the above-mentioned danger from occurring.

[0058] In order to improve the stability when the upper cover 22 is closed, two hydraulic buffer rods 13 are provided. The two hydraulic buffer rods 13 are arranged along the length direction of the upper cover 22 , and the two hydraulic buffer rods 13 are provided along the width direction of the upper cover 22 .

[0059] In one embodiment, a mounting protrusion 213 is provided at one end of the second wide strip 211 close to the hinged edge of the upper cover, and two mounting screw holes 214 are provided on the mounting protrusion 213 in the vertical direction. The hydraulic buffer rod 13 includes a piston rod 131 and a cylinder 132. The end of the piston rod 131 away from the cylinder 132 is provided with a first thread head 133, and the end of the cylinder 132 away from the piston rod 131 is provided with a second thread head 134. A cover inner plate 23 is provided on the inner side of the upper cover 22. The second thread head 134 is threadedly connected to the mounting screw hole 214. The first thread head 133 is threadedly connected to the cover inner plate 23. Two mounting screw holes 214 are provided in the vertical direction, so the distances between the two mounting screw holes 214 and the cover inner plate 23 are different. Therefore, the piston rod 131 and any one of the mounting screw holes 214 can be selected for connection, thereby changing the resistance encountered by the upper cover 22 when it is closed.

[0060] The side wall of the upper fixed frame 21 is provided with an inwardly recessed locking groove 215, which is arranged on the side of the upper fixed frame 21 away from the hinged edge of the upper cover. A locking plate is arranged at the upper end of the locking groove 215, and a locking hole 217 is arranged through the locking plate. The upper cover 22 is provided with a locking rod 216 that cooperates with the locking hole 217. When the upper cover 22 is closed, the locking rod 216 can just pass through the locking hole 217. A locking rod 216 through-hole is arranged at the end of the locking rod 216. The lock and the locking rod 216 through-hole are connected to lock the upper cover 22 and the upper fixed frame 21. In this embodiment, the locking groove 215, the locking plate, the locking hole 217 and the locking rod 216 are all arranged in two groups, and are arranged along the length direction of the upper fixed frame 21.

[0061] In order to facilitate the pushing and pulling of the folding storage cabinet, an inwardly recessed side wall concave portion 31 is provided on the first side wall 3, and a handle 7 is rotatably provided in the side wall concave portion 31. The side wall concave portion 31 is provided with a rotating shaft 71 at both ends along the width direction of the first side wall 3, and the two ends of the handle 7 are rotatably connected to the rotating shaft 71. When the handle 7 is acted upon by gravity, it can be in a vertical state, and the handle 7 is stored in the side wall concave portion 31 without protruding from the end surface of the first side wall 3.

[0062] It should be noted that the "hinge" connection method in the present application adopts a hinge connection method, so that when folded, two adjacent panels can fit together in the folded state. For example, several side wall panels 41 are connected by hinges, so that the side wall baffles can be folded together, thereby reducing the folded volume.

[0063] The use principle of the present application is as follows: the bottom wall 1 and the surrounding first side walls 3, second side walls 4 and top wall 2 in this embodiment together form a box body, forming a storage space inside. Before transportation, the folding storage cabinet needs to be folded.

[0064] When folding, first rotate the first side wall 3 around the first side so that the first side wall 3 is attached to the bottom wall 1, so that the two first side walls 3 are attached to the two ends of the length direction of the bottom wall 1. Then fold the second side wall 4. When folding the second side wall 4, first fold a plurality of side wall panels 41, and then fold the folded side wall panels 41 toward the bottom wall 1, so that the second side wall 4 is located above the first side wall 3. At this time, the two folded second side walls 4 are located on both sides of the width direction of the bottom wall 1; at this time, the top wall 2 is located above the second side wall 4. Then place the roller 6 in the seat cover 5 or in the gap between the top wall 2 and the bottom wall 1, and the overall structure is folded.

[0065] When the folded storage cabinet needs to be unfolded, the roller 6 is first taken out, and then the top wall 2 can be lifted by the device, so that the side wall single plate 41 is unfolded to form the second side wall 4, and the movement of the top wall 2 is stopped when the second side wall 4 is in a vertical state, and then the first side wall 3 is rotated around the first side, and the first side wall 3 is in a vertical state, and then the adjacent side walls of the first side wall 3 and the second side wall 4 are connected and fixed by a connecting member. In this embodiment, the connecting member is connected by a rivet connection, so that the first side wall 3 and the second side wall 4 are fixedly connected, so that the first side wall 3, the second side wall 4 and the top wall 2 are surrounded by a box body, and a storage space is formed inside. Then the roller 6 is fixedly installed at the bottom of the bottom wall 1.

[0066] Therefore, in the present application, when transportation is required, the first side wall 3 and the second side wall 4 can be folded toward the bottom wall 1 so that the whole is in a folded state, and the overall volume after folding is small, thereby reducing the space occupied by a single product and reducing transportation costs; and when unfolding is required, the top wall 2 is directly pulled up so that the second side wall 4 is in a vertical state, and then the first side wall 3 is unfolded to make it in a vertical state, and the first side wall 3 and the second side wall 4 are connected to complete the assembly of the overall structure, which has the characteristic of easy assembly.

[0067] Example 3: Reference Figures 1 to 10 As shown, the difference between the structure of this embodiment and that of embodiment 2 is that the first side wall 3 is also configured as a plurality of second single plates hinged to each other, and the plurality of second single plates are folded. It should be noted that the thickness of the plurality of second single plates constituting the first side wall 3 after folding is d, and H2-H1≥d, so that when the first side wall 3 is folded on the bottom wall 1, the second side wall 4 can be folded on the upper end of the first side wall 3, and the first side wall 3 does not affect the folding of the second side wall 4.

[0068] Example 4: Reference Figures 1 to 10As shown, the structure of this embodiment is similar to that of embodiment 1 or embodiment 2 or embodiment 3, except that the inner side of the upper cover 22 in this embodiment is provided with a first reinforcing rib 81 arranged along its length direction, and the first reinforcing rib 81 can improve the overall strength of the upper cover 22.

[0069] A plurality of second reinforcing ribs 82 arranged along the length direction of the side wall single plate 41 are disposed on the inner side thereof. The second reinforcing ribs 82 are arranged along the width direction thereof. The second reinforcing ribs 82 can improve the strength of the side wall single plate 41 .

[0070] The inner side of the first side wall 3 is provided with third reinforcing ribs 83 arranged along the width direction thereof, and two third reinforcing ribs 83 are provided, and the two third reinforcing ribs 83 are respectively arranged at the upper and lower ends of the side wall recess 31 .

[0071] The inner side wall of the lower cover 12 is provided with a fourth reinforcing rib 84 arranged along its width direction. The first reinforcing rib 81 can improve the strength of the lower cover 12. At the same time, when in a folded state, the first side wall 3 is folded on both sides of the fourth reinforcing rib 84, thereby not affecting the folding of the first side wall 3.

[0072] Example 5: Reference Figures 1 to 9 As shown, the structure of this embodiment is similar to that of Embodiment 1 or Embodiment 2 or Embodiment 3 or Embodiment 4, except that, in this embodiment, a wire channel 85 is provided on the side wall of the second side wall 4, and when the wire channel 85 is not in use, the wire channel 85 is blocked by a channel cover.

[0073] Example 6: Reference Fig.11 As shown, the structure of this embodiment is similar to that of embodiment 1, embodiment 2, embodiment 3, embodiment 4, or embodiment 5, except that a fixing structure is provided between the top wall 2 and the bottom wall 1, and the fixing structure can fix the top wall 2 and the bottom wall 1 when the box is in a folded state, thereby limiting the relative displacement between the top wall 2 and the bottom wall 1. Thus, when the box in a folded state is transported or transferred, the vibration of the box during transportation is reduced, and the relative displacement between the top wall 2 and the bottom wall 1 during transfer of the box is reduced.

[0074] The fixing structure in this embodiment includes a rotating piece 91 and a fixing pin 92. Specifically, one end of the rotating piece 91 is rotatably connected to the second wide strip 211 of the upper fixed frame 21, and the rotating piece 91 is rotatably arranged on the outside of the second wide strip 211. The fixing pin 92 is fixedly arranged on the first wide strip 111 of the lower fixed frame 11, and the fixing pin 92 is also arranged on the outside of the lower fixed frame 11. A hook portion 911 is arranged at the end of the rotating piece 91 away from the second wide strip 211. When the box body is in a folded state, the rotating piece 91 is rotated so that the hook portion 911 hooks the fixing pin 92. The length of the rotating piece 91 corresponds to the spacing between the upper fixed frame 21 and the lower fixed frame 11 on the folded state box body. The hook portion 911 hooks the fixing pin 92, so that when the box body is transported, the top wall 2 and the bottom wall 1 are fixed, so that when the box body is transported and transferred in a folded state, the relative displacement between the top wall 2 and the bottom wall 1 can be reduced, so that the box body in a folded state can be more stable when transported and transferred.

[0075] In addition, an inwardly recessed annular groove is provided in the circumferential direction of the side wall of the fixing pin 92 in this embodiment, so that the hook portion 911 can be more stable when hooking the fixing pin 92 .

[0076] Of course, the rotating piece 91 and the first wide strip 111 of the lower fixed frame 11 can also be rotatably connected, and the fixing pin 92 can be fixedly set on the second wide strip 211 of the upper fixed frame 21 .

[0077] In addition, the fixed structure can be set into two or four groups. The two or four groups of fixed structures are arranged symmetrically and symmetrically on both sides of the length direction of the box. The two or four groups of fixed structures have a fixing effect on the two ends of the length direction of the box, and can better fix the box in the folded state.

[0078] Example 7: Reference Fig.12 As shown, the structure of this embodiment is similar to that of embodiment 1 or embodiment 2 or embodiment 3 or embodiment 4 or embodiment 5, except that in embodiment 1 or embodiment 2 or embodiment 3 or embodiment 4 or embodiment 5 or embodiment 6, the first side wall 3 and the second side wall 4 are connected by rivets. Although this connection method makes the overall structure of the box body more solid after connection, it is difficult to restore to the folded state again once the connection is fixed by rivets. Therefore, in this embodiment, a connection structure is set between the first side wall 3 and the top wall 2 or the second side wall 4. When the box body is in the unfolded state, the connection structure can temporarily fix the first side wall 3 and the second side wall 4 or the top wall 2. When the box body needs to be folded again, the connection structure can be opened to separate the first side wall 3 and the second side wall 4 or the top wall 2, thereby facilitating the box body to be folded again.

[0079] The connection structure in this embodiment includes a connection piece 93 rotatably arranged on the second wide strip 211 and a locking piece 94 arranged on the first side wall 4. An opening groove 941 is arranged on the locking piece 94, and a bending piece 931 is arranged at one end of the connection piece 93 away from the second wide strip 211. The bending piece 931 and the connection piece 93 are at a certain angle. In this embodiment, the angle between the bending piece 931 and the connection piece 93 is 90°. Fig.12 As shown, when the box is in the unfolded state, the connecting piece 93 is located in the opening groove 941 (as shown in FIG. Fig.12 As shown by the solid line in the figure), through the cooperation between the opening groove 941 and the connecting piece 93, the connecting piece 93 and the locking piece 94 are in a locked state, and the first side wall 3 and the upper fixed frame 21 are in a connected state.

[0080] When the box body needs to be converted from the unfolded state to the folded state, the connecting piece 93 can be rotated so that the connecting piece 93 is separated from the opening groove 941 (such as Fig.12 As shown by the dotted line in FIG. 1 ), the locking state between the connecting piece 93 and the locking piece 94 can be released, the first side wall 3 and the second side wall 4 can be folded normally, and the box body can return to the folded state.

[0081] In addition, by setting the connecting piece 93 on the second wide strip 211 and setting the locking piece 94 on the first side wall 3, the locking piece 94 is located below the connecting piece 93. When the box is in the unfolded state, the connecting piece 93 is in the slot 941, and the connecting piece 93 is located in the vertical direction. That is to say, in this state, the connecting piece 93 will be kept in the vertical direction by the action of gravity, so that when in use, except for human intervention, the connecting piece 93 will not be separated from the opening slot 941, thereby ensuring that the box can always be in the unfolded state and will not affect normal use. Only when the box needs to be folded again, the connecting piece 93 is rotated by human action, and the connecting piece 93 is separated from the opening slot 941, at this time, the box can be folded. In addition, the connection structure in the present application is arranged on the inner side of the box, that is, when the box is in the unfolded state, the connection structure is arranged on the inner side of the box, so that it can effectively prevent the connecting piece 93 from being touched by mistake.
