Description

Technical Field

[0001] This utility model relates to the field of construction site storage boxes, and more specifically, it relates to a folding storage cabinet. Background Technology

[0002] Construction site storage boxes are commonly used on construction sites to store various tools, hardware, and equipment. Existing boxes are typically supported by heavy-duty steel and are not foldable, resulting in a large transport volume and increased transportation costs. Utility Model Content

[0003] This invention overcomes the problem that existing construction site storage boxes cannot be folded, which increases transportation costs. It provides a foldable storage cabinet that can be folded during transportation, thereby reducing transportation costs.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a folding storage cabinet, comprising: a lower wall and an upper wall, wherein a first vertical wall and a second vertical wall are hinged to the side of the lower wall; two first vertical walls and two second vertical walls are provided, and are arranged opposite to each other on both sides of the lower wall; the upper side of the second vertical wall is hinged to the upper wall, and the second vertical wall includes a plurality of vertical wall panels that are hinged to each other.

[0005] When transportation is required, the first and second vertical walls can be folded towards the lower wall, so that the whole structure is in a folded state and the overall volume after folding is small, thereby reducing the space occupied by a single product during transportation and thus reducing transportation costs. When it needs to be unfolded, the upper wall is pulled up to make the second vertical wall vertical, and then the first vertical wall is unfolded to make it vertical. The first and second vertical walls are then fixedly connected by connectors to complete the assembly of the overall structure, which has the characteristics of convenient assembly.

[0006] Preferably, the hinged edge between the first vertical wall and the lower wall is called the first edge, the hinged edge between the second vertical wall and the lower wall is called the second edge, the vertical height between the first edge and the lower wall is H1, the vertical height between the second edge and the lower wall is H2, the thickness of the first vertical wall is D, and H2-H1≧D.

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

[0008] Preferably, the device also includes several fixed channels and several rollers. The fixed channels are fixedly installed at the bottom of the lower wall, and the rollers are detachably installed at the bottom of the lower wall. The fixed channels are arranged on both sides of the width direction of the lower wall.

[0009] The fixed channels are arranged along both sides of the lower wall's width, allowing the forklift's two grippers to pass through these channels on either side. This ensures that the center of gravity falls between the forklift's two grippers during transport, improving the stability of the folding storage cabinet. Removable rollers are installed on the lower wall, allowing them to be detached and placed within the fixed channels or between the lower and upper walls during transport, thus reducing the overall size.

[0010] Preferably, the fixed channel includes a first plate, a second plate, and a third plate; the second plate and the third plate are respectively disposed at both ends of the first plate; and the rollers are detachably disposed at the bottom of the first plate.

[0011] By placing the rollers at the bottom of the first panel, the height of the lower wall is the sum of the roller height and the height of the fixed channel, thus increasing the overall height of the folding locker chassis. Given the harsh environment and uneven ground often found on construction sites, placing the rollers at the bottom of the first panel increases the height of the folding locker chassis, thereby improving its mobility on construction sites.

[0012] Preferably, the first plate is disposed on the side near the width direction of the lower wall, and the first plate is inclined towards the side near the lower wall.

[0013] The fixed channels are set on both sides of the width direction of the lower wall. This makes the first plate on the fixed channels on both sides of the width direction form a "figure-eight" structure on both sides of the lower wall. This allows the fixed channels on the lower wall to provide stable support for the folding storage cabinet and also improves the overall strength of the side walls.

[0014] Preferably, the upper wall includes an upper mounting frame and an upper cover, with one side of the upper cover hinged to one side of the upper mounting frame; the top edge of the second vertical wall is hinged to the upper mounting frame.

[0015] The top cover can rotate around the hinged edge, allowing the folding locker to be opened and closed as needed.

[0016] Preferably, a support rod is provided between the upper mounting frame and the upper cover, with one end of the support rod connected to the upper mounting frame and the other end of the support rod 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 mounting frame, and the other end is connected to the upper cover. When the upper cover is opened, due to its considerable weight, it may suddenly close under the force of gravity, potentially trapping the worker's hand and causing a hazard. Therefore, a hydraulic buffer rod is installed. When the upper cover closes, the hydraulic buffer rod cushions the opening, allowing the cover to close slowly and preventing the aforementioned danger.

[0018] Preferably, the side wall of the upper mounting frame is provided with a lock groove, which is recessed inward. A lock plate is provided at the upper end of the lock groove, and a lock hole is provided through the lock plate. The upper cover is provided with a lock rod that mates with the lock hole.

[0019] When the top cover is closed, the locking rod can pass through the lock hole. A locking rod through hole is provided at the end of the locking rod. By connecting the lock and the locking rod through hole, the top cover and the upper mounting frame can be locked together.

[0020] Preferably, the first vertical wall is provided with a vertical wall recess, which is recessed inward, and a handle is rotatably provided inside the vertical wall recess.

[0021] The handle design makes it easy to push and pull the folding storage cabinet.

[0022] Preferably, the vertical wall recess is provided with a rotating shaft at each end along the width direction of the first vertical wall, and the two ends of the handle are rotatably connected to the rotating shaft.

[0023] The vertical wall recess has a rotating shaft at each end along the width of the first vertical wall, and the two ends of the handle are rotatably connected to the rotating shafts at both ends.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] (1) In this utility model, when transportation is required, the first vertical wall and the second vertical wall can be folded towards the lower 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 during transportation and thus reducing transportation costs.

[0026] (2) When it is necessary to unfold, simply pull up the upper wall to make the second vertical wall vertical, then unfold the first vertical wall to make it vertical, and fix the first vertical wall and the second vertical wall together with the connector to complete the assembly of the whole structure. It has the characteristics of easy assembly.

[0027] (3) The second vertical wall is formed by hinged connection of several vertical wall panels, so that when folded, the two side wall panels can be folded together, so that the volume after folding can be smaller.

[0028] (4) A detachable roller is installed on the lower wall. During transportation, the roller can be removed and placed in a fixed channel or between the lower and upper walls, thereby reducing the overall volume and transportation costs.

[0029] (5) The side wall of the upper mounting frame is provided with an inwardly recessed locking groove, thereby reducing the volume after folding and further reducing transportation costs;

[0030] (6) When the handle is subjected to gravity, it can be in a vertical state and the handle is stored in the recess of the vertical wall without protruding from the end face of the first vertical wall. In the folded state, the handle can be retracted into the recess of the vertical wall, reducing the overall volume after folding.

[0031] (7) The fixed channel setting makes it convenient for forklifts to pass through the fixed channel, thereby saving the trouble of using forklift brackets during the transportation of folding lockers, thus improving the efficiency of transporting folding lockers.

[0032] (8) The rollers are set at the bottom of the first plate, which can increase the height of the folding locker chassis, thereby improving the folding locker's mobility on the construction site. Attached Figure Description

[0054] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0055] Example 1: Refer to Figures 1 to 10As shown, a folding storage cabinet includes: a lower wall 1 and an upper wall 2. The lower wall 1 is hinged with a first vertical wall 3 and a second vertical wall 4. There are two of each of the first vertical wall 3 and the second vertical wall 4, which are arranged opposite each other on both sides of the lower wall 1. The first vertical wall 3 is hinged to the upper wall 2, and the second vertical wall 4 includes a plurality of vertical wall panels 41 that are hinged to each other. In the folded state, the vertical wall panels 41 are folded, and the first vertical wall 3 and the second vertical wall 4 are folded around the hinge edge with the lower wall 1 and stored between the upper wall 2 and the lower wall 1.

[0056] In this embodiment, the lower wall 1, the surrounding first vertical walls 3, second vertical walls 4, and the upper wall 2 together form a box, creating a storage space inside. The first vertical walls 3 and second vertical walls 4 are hinged to the lower wall 1, allowing them to rotate around the side of the lower wall 1. This allows the first vertical walls 3 and second vertical walls 4 to fold towards the lower wall 1 during folding (e.g., ...). Figure 1 (As shown by the middle arrow). This design ensures that the relatively positioned second vertical walls 4 do not interfere with each other when folded, thus affecting the folding effect. Simultaneously, it allows the second vertical walls 4 to have a certain height when unfolded, thereby increasing the usable volume of the enclosure. Therefore, the second vertical walls 4 are configured as several hinged vertical wall panels 41. When unfolded, the vertical wall panels 41 can form a relatively high second vertical wall 4, increasing the usable volume of the cavity. Simultaneously, when folded, the several vertical wall panels 41 can fold together, so that the overall width of the folded second vertical wall 4 is only the width of a single vertical wall panel 41. This allows the two folded second vertical walls 4 to be distributed on both sides of the lower wall 1, preventing interference after folding.

[0057] When needed, the folded box needs to be unfolded. Since the upper wall 2 is hinged to the second vertical wall 4, the upper wall 2 can be pulled up directly, so that the second vertical wall 4 is in a vertical state perpendicular to the lower wall 1. Then, the first vertical wall 3 is unfolded, so that the first vertical wall 3 is in a vertical state perpendicular to the lower wall 1. Finally, the connection between the first vertical wall 3 and the second vertical wall 4 is fixed to complete the assembly of the box.

[0058] Therefore, in this embodiment, when transportation is required, the first vertical wall 3 and the second vertical wall 4 can be folded towards the lower 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 transportation costs; when it needs to be unfolded, the upper wall 2 is pulled up directly, so that the second vertical wall 4 is in a vertical state, and then the first vertical wall 3 is unfolded to be in a vertical state. The first vertical wall 3 and the second vertical wall 4 are fixedly connected by connectors, thus completing the assembly of the overall structure, which has the characteristics of convenient assembly.

[0059] Example 2: Refer to Figures 1 to 10As shown, a folding storage cabinet includes: a lower wall 1 and an upper wall 2. The lower wall 1 is hinged with a first vertical wall 3 and a second vertical wall 4. There are two of each of the first vertical wall 3 and the second vertical wall 4, which are arranged opposite each other on both sides of the lower wall 1. The first vertical wall 3 is hinged to the upper wall 2, and the second vertical wall 4 includes a plurality of vertical wall panels 41 that are hinged to each other. In the folded state, the vertical wall panels 41 are folded, and the first vertical wall 3 and the second vertical wall 4 are folded around the hinge edge with the lower wall 1 and stored between the upper wall 2 and the lower wall 1.

[0060] The first vertical wall 3 is located at both ends of the lower wall 1 in the length direction, and the second vertical wall 4 is located at both ends of the lower wall 1 in the width direction. The horizontal length of the first vertical wall 3 is shorter than the horizontal length of the second vertical wall 4.

[0061] The hinge edge between the first vertical wall 3 and the lower wall 1 is defined as the first edge, and the hinge edge between the second vertical wall 4 and the lower wall 1 is defined as the second edge. The vertical height of the first edge from the lower wall 1 is H1, and the vertical height of the second edge from the lower wall 1 is H2, where H2 is greater than H1. The thickness of the first vertical wall 3 is D, and H2 - H1 ≥ D. With this configuration, when the first vertical wall 3 and the lower wall 1 are in the folded state, the folded first vertical wall 3 can be located below H2, i.e., below the second edge, without affecting the folding of the second vertical wall 4, resulting in a smaller overall folded volume.

[0062] In addition, such as Figure 3 As shown, in this embodiment, the first vertical wall 3 is a single integral plate structure. Therefore, in the folded state, after the first vertical wall 3 is attached to the lower wall 1, in order to prevent the two folded first vertical walls 3 from interfering with each other, the height of the first vertical wall 3 is H3, the length of the lower wall 1 is L, and 2*H3≦L. Thus, when the first vertical wall 3 is folded, the two first vertical walls 3 can be attached to both sides of the lower wall 1 along its length.

[0063] It should be noted that, in order for the second vertical wall 4 to fold together with several vertical wall panels 41 during folding, the number of vertical wall panels 41 needs to be set to an even number. In this embodiment, the second vertical wall 4 is formed by hinged two vertical wall panels 41 together, so that the two side wall panels 41 can fold together during folding. Of course, the number of vertical wall panels 41 can also be set to 4 depending on the actual situation (e.g., Figure 9 (as shown), 6, etc.

[0064] The first vertical wall 3 is configured as several vertical wall panels 41 that are hinged to each other, so that when the box is in the state, the vertical wall panels 41 can be unfolded to form a tall first vertical wall 3, ensuring the usable volume of the folding storage cabinet in the unfolded state. At the same time, when folded, the several vertical wall panels 41 can be stacked together, so that the overall width of the folded second vertical wall 4 is only the width of a single vertical wall panel 41. This allows the two folded first vertical walls 3 to be distributed on both sides of the lower wall 1, so that the two second vertical walls 4 will not interfere with each other after folding.

[0065] To facilitate easier movement of the folding lockers during use, and to allow for convenient transfer using equipment such as forklifts and clamping machines, such as... Figure 2 As shown, several fixed channels 5 and detachable rollers 6 are provided at the bottom of the lower wall 1. The fixed channels 5 are arranged on both sides along the width direction of the lower wall 1.

[0066] In this embodiment, four fixed channels 5 and four rollers 6 are provided. Therefore, on each side of the lower wall 1 in the width direction, two fixed channels 5 and two rollers 6 are provided.

[0067] The fixed channel 5 allows the forklift's clamping arms to easily pass through it, eliminating the need for a forklift support during the handling of the folding storage cabinet and improving transport efficiency. Furthermore, the fixed channel 5 provides support for the folding storage cabinet during transport and in actual use. Therefore, to enhance the stability of forklift transport of the folding storage cabinet, the fixed channel 5 is positioned along both sides of the lower wall 1's width direction. This allows the two clamping arms of the forklift to pass through the fixed channels 5 on both sides of the width direction, ensuring that the center of gravity falls between the two clamping arms during transport, thus improving the stability of the folding storage cabinet during transport.

[0068] A detachable roller 6 is provided on the lower wall 1. During transportation, the roller 6 can be removed and placed in the fixed channel 5 (e.g., Figure 7 (as shown) or between the lower wall 1 and the upper wall 2 (as shown) Figure 8 (as shown) or between the vertical wall panel 41 and the upper wall 2 (as shown) Figure 9 As shown in the figure, this reduces the overall volume; and when in use, it can be installed on the lower wall 1, making it convenient to push the folding storage cabinet to move. Furthermore, a roller stop 61 can be installed on the rollers 6, which can be locked at any time as needed during use to prevent the cabinet from moving.

[0069] In one embodiment, the fixed channel 5 includes a first plate 51, with a second plate 52 and a third plate 53 respectively disposed at both ends of the first plate 51. A roller 6 is detachably disposed at the bottom of the first plate 51. A mounting plate 62 is disposed at the top of the roller 6, and the mounting plate 62 is fixedly connected to the first plate 51 by bolts, thus allowing the roller 6 to be detachably connected to the first plate 51. The roller 6, like the fixed channel 5, can be directly connected to the bottom of the lower wall 1. However, in this embodiment, the roller 6 is disposed at the bottom of the first plate 51, making the height of the lower wall 1 the sum of the height of the roller 6 and the height of the fixed channel 5, thereby increasing the overall height of the folding locker chassis. Since construction sites often have harsh environments and uneven surfaces, placing the roller 6 at the bottom of the first plate 51 increases the height of the folding locker chassis, thereby improving the folding locker's mobility on construction sites.

[0070] To improve the overall structural stability, the first plate 51 is positioned on the side closest to the lower wall 1 in the width direction, and the first plate 51 is inclined towards the side closest to the lower wall 1 (e.g., Figure 2 (As shown). Since the fixed channels 5 are set on both sides of the width direction of the lower wall 1, the first plates 51 on the fixed channels 5 on both sides of the width direction form a "figure-eight" structure on both sides of the lower wall 1. This makes the fixed channels 5 on the lower wall 1 provide stable support for the folding storage cabinet and also improves the overall strength of the side wall.

[0071] In one embodiment, the upper wall 2 and the lower wall 1 have similar structures. The lower wall 1 includes a lower mounting frame 11 and a lower cover 12, which are fixedly connected. The upper wall 2 includes an upper mounting frame 21 and an upper cover 22, with one side of the upper cover 22 hinged to one side of the upper mounting frame 21. The sidewall where the upper cover 22 and the upper mounting frame 21 are hinged is the hinge edge of the upper cover, allowing the upper cover 22 to rotate around the hinge edge, thereby opening and closing the folding storage cabinet when needed.

[0072] The lower mounting frame 11 includes two first wide strips 111 and two first long strips 112, with the two first wide strips 111 and the two first long strips 112 arranged opposite each other. The first wide strips 111 are hinged to the first vertical wall 3, and the first long strips 112 are hinged to the second vertical wall 4. The height of the first long strip 112 is higher than the height of the first wide strips 111. This ensures that when the first vertical wall 3 and the lower wall 1 are in the folded state, the upper surface of the first side is lower than the upper surface of the first long strip 112, thus not affecting the folding of the second vertical wall 4.

[0073] The upper mounting frame 21 includes two second wide strips 211 and two second long strips 212, with the two second wide strips 211 and the two second long strips 212 also positioned opposite each other. The two second long strips 212 are hinged to the top ends of the two second vertical walls 4, respectively. The height of the second long strips 212 is greater than that of the second wide strips 211.

[0074] A support rod is provided between the upper mounting frame 21 and the upper cover 22. 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 mounting frame 21, and the other end is connected to the upper cover 22. When the upper cover 22 is opened, due to its considerable weight, it may suddenly close under the force of gravity, potentially trapping the worker's hand and causing a hazard. Therefore, the hydraulic buffer rod 13 is provided. When the upper cover 22 closes, the hydraulic buffer rod 13 cushions the opening, allowing the upper cover 22 to close slowly, thereby preventing the aforementioned hazard.

[0075] To improve the stability of the cover 22 when it is closed, two hydraulic buffer rods 13 are provided. The two hydraulic buffer rods 13 are arranged along the length of the cover 22 and along the width of the cover 22.

[0076] In one embodiment, the second wide strip 211 has a mounting protrusion 213 at one end near the hinge edge of the upper cover. The mounting protrusion 213 has two mounting screw holes 214 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 has a first threaded head 133, and the end of the cylinder 132 away from the piston rod 131 has a second threaded head 134. An inner cover plate 23 is provided on the inner side of the upper cover 22. The second threaded head 134 is threaded to the mounting screw holes 214. The first threaded head 133 is threaded to the inner cover plate 23. Since there are two mounting screw holes 214 in the vertical direction, the distance between the two mounting screw holes 214 and the inner cover plate 23 is not the same. Therefore, the resistance experienced by the upper cover 22 when closing can be changed by selecting either the piston rod 131 and one of the mounting screw holes 214 for connection.

[0077] The upper mounting frame 21 has an inwardly recessed locking groove 215 on its side wall, located on the side of the upper mounting frame 21 away from the hinge edge of the upper cover. A locking plate is located at the upper end of the locking groove 215, with a through-hole 217 on the locking plate. The upper cover 22 has a locking rod 216 that mates with the through-hole 217. When the upper cover 22 is closed, the locking rod 216 passes precisely through the through-hole 217. A through-hole is located at the end of the locking rod 216. Connecting the lock and the through-hole lock rod 216 locks the upper cover 22 and the upper mounting frame 21. In this embodiment, two sets of the locking groove 215, locking plate, through-hole 217, and locking rod 216 are provided, and they are arranged along the length of the upper mounting frame 21.

[0078] To facilitate the sliding and folding of the storage cabinet, an inwardly recessed vertical wall recess 31 is provided in the first vertical wall 3, and a handle 7 is rotatably mounted within the vertical wall recess 31. A pivot 71 is provided at both ends of the vertical wall recess 31 along the width direction of the first vertical wall 3, and the two ends of the handle 7 are rotatably connected to the pivot 71. This ensures that when the handle 7 is subjected to gravity, it remains vertical and is retracted within the vertical wall recess 31, without protruding from the end face of the first vertical wall 3.

[0079] It should be noted that the "hinged" connection method in this application adopts the hinge connection method, which allows two adjacent boards to fit together in the folded state. For example, several vertical wall panels 41 are connected by hinges, so that the side wall panels can fold together, thereby reducing the volume after folding.

[0080] The working principle of this application is as follows: In this embodiment, the lower wall 1, the first vertical wall 3, the second vertical wall 4, and the upper wall 2 together form a box, creating a storage space inside. Before transportation, the folding storage cabinet needs to be folded.

[0081] During folding, firstly, the first vertical wall 3 is rotated around the first side, so that the first vertical wall 3 fits against the lower wall 1, with the two first vertical walls 3 fitting against the two ends of the lower wall 1 along its length. Then, the second vertical wall 4 is folded. When folding the second vertical wall 4, several vertical wall panels 41 are folded first, and then the folded vertical wall panels 41 are folded towards the lower wall 1, so that the second vertical wall 4 is folded above the first vertical wall 3. At this point, the two folded second vertical walls 4 are located on either side of the lower wall 1 in the width direction; the upper wall 2 is located above the second vertical wall 4. Finally, the roller 6 is placed in the fixed channel 5 or in the gap between the upper wall 2 and the lower wall 1, completing the overall folding structure.

[0082] When the folded storage cabinet needs to be unfolded, first remove the rollers 6. Then, use the equipment to lift the top cover, causing the vertical wall panel 41 to unfold and form the second vertical wall 4. Stop when the second vertical wall 4 is in a vertical position. Then, rotate the first vertical wall 3 around the first side to make the first vertical wall 3 vertical. Then, connect and fix the adjacent side walls of the first vertical wall 3 and the second vertical wall 4 with connectors. In this embodiment, the connectors are connected by rivets, so that the first vertical wall 3 and the second vertical wall 4 are fixedly connected, and the first vertical wall 3, the second vertical wall 4 and the upper wall 2 together form a box body, forming a storage space inside. Then, fix the rollers 6 to the bottom of the lower wall 1 (or the bottom of the first panel 51).

[0083] Therefore, in this application, when transportation is required, the first vertical wall 3 and the second vertical wall 4 can be folded towards the lower 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 thus reducing transportation costs; when it needs to be unfolded, the upper wall 2 is pulled up directly, so that the second vertical wall 4 is in a vertical state, and then the first vertical wall 3 is unfolded to be in a vertical state. The first vertical wall 3 and the second vertical wall 4 are connected to complete the assembly of the overall structure, which has the characteristics of convenient assembly.

[0084] Example 3: Reference Figures 1 to 10 As shown, the structural difference between this embodiment and Embodiment 2 is that the first vertical wall 3 is also configured as several vertical wall panels 41, and several side wall baffles are folded. It should be noted that the thickness of the several vertical wall panels 41 that make up the first vertical wall 3 after folding is d, and H2-H1≥d, so that when the first vertical wall 3 is folded on the lower wall 1, the second vertical wall 4 can be folded on the upper end of the first vertical wall 3, and the first vertical wall 3 does not affect the folding of the second vertical wall 4.

[0085] Example 4: Reference Figures 1 to 10 As shown, this embodiment is similar in structure to embodiment 1, embodiment 2, or embodiment 3. The difference is 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. The first reinforcing rib 81 can improve the overall strength of the upper cover 22.

[0086] The inner side of the vertical wall panel 41 is provided with a number of second reinforcing ribs 82 arranged along its length direction and along its width direction. The second reinforcing ribs 82 can improve the strength of the vertical wall panel 41.

[0087] The inner side of the first vertical wall 3 is provided with a third reinforcing rib 83 arranged along its width direction, and there are two third reinforcing ribs 83, which are respectively arranged at the upper and lower ends of the vertical wall recess 31.

[0088] The inner sidewall 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 it is in the folded state, the first vertical wall 3 is folded on both sides of the fourth reinforcing rib 84, so as not to affect the folding of the first vertical wall 3.

[0089] Example 5: Refer to Figures 1 to 10 As shown, this embodiment is similar in structure to embodiment 1, embodiment 2, embodiment 3, or embodiment 4. The difference is that in this embodiment, an electrical wire channel 85 is provided on the side wall of the second vertical wall 4. When the electrical wire channel 85 is not in use, the electrical wire channel 85 is blocked by the channel cover.

[0090] Example 6: Refer to Figure 11 As shown, this embodiment is similar in structure to that of Embodiment 1, 2, 3, 4, or 5, except that a fixing structure is provided between the upper wall 2 and the lower wall 1. This fixing structure secures the upper wall 2 and lower wall 1 when the box is in a folded state, limiting the relative displacement between them. This prevents vibrations during transport and reduces relative displacement between the upper wall 2 and lower wall 1 during transport, especially when the box is in a folded state.

[0091] 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 mounting frame 21, and the rotating piece 91 is rotatably disposed on the outside of the second wide strip 211. The fixing pin 92 is fixedly disposed on the first wide strip 111 of the lower mounting frame 11, and the fixing pin 92 is also disposed on the outside of the lower mounting frame 11. A hook portion 911 is provided at the end of the rotating piece 91 away from the second wide strip 211. When the box 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 distance between the upper mounting frame 21 and the lower mounting frame 11 on the folded box. The hook portion 911 hooks the fixing pin 92, so that the upper wall 2 and the lower wall 1 are fixed when the box is transported, thereby reducing the relative displacement between the upper wall 2 and the lower wall 1 during transportation and transfer of the folded box, making the transportation and transfer of the folded box more stable.

[0092] In addition, in this embodiment, the vertical wall of the fixing pin 92 is provided with an inwardly recessed annular groove in the circumferential direction, so that the hook portion 911 can hook the fixing pin 92 more stably.

[0093] Of course, the rotating piece 91 and the first wide strip 111 of the lower mounting 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 mounting frame 21.

[0094] In addition, the fixing structure can be set in two or four groups. The two or four groups of fixing structures are arranged symmetrically on both sides of the length of the box. The two or four groups of fixing structures play a role in fixing the two ends of the length of the box, which can better fix the box in the folded state.

[0095] Example 7: Refer to Figure 12 As shown, this embodiment is similar in structure to Embodiment 1, 2, 3, 4, or 5, except that in Embodiment 1, 2, 3, 4, 5, or 6, the first vertical wall 3 and the second vertical wall 4 are connected by rivets. While this connection method makes the overall structure of the box more robust, it is difficult to return it to a folded state once the connection is made with rivets. Therefore, in this embodiment, a connecting structure is provided between the first vertical wall 3 and the upper wall 2 or the second vertical wall 4. When the box is in the unfolded state, the connecting structure can temporarily fix the first vertical wall 3 and the second vertical wall 4 or the upper wall 2. When the box needs to be folded again, the connecting structure can be opened, separating the first vertical wall 3 and the second vertical wall 4 or the upper wall 2, thus facilitating the folding of the box again.

[0096] The connection structure in this embodiment includes a connecting piece 93 rotatably mounted on the second wide bar 211 and a locking piece 94 mounted on the first vertical wall 4. The locking piece 94 has an opening slot 941, and the end of the connecting piece 93 furthest from the second wide bar 211 has a bent piece 931. The bent piece 931 and the connecting piece 93 form a certain angle; in this embodiment, the angle between the bent piece 931 and the connecting piece 93 is 90°. Figure 12 As shown, when the housing is in the unfolded state, the connecting piece 93 is located within the opening slot 941 (as shown). Figure 12 (As shown by the solid line inside), through the cooperation of the opening slot 941 and the connecting piece 93, the connecting piece 93 and the locking piece 94 are locked at this time, and the first vertical wall 3 and the upper mounting frame 21 are connected.

[0097] When it is necessary to change the box from the unfolded state to the folded state, the connecting piece 93 can be rotated to separate the connecting piece 93 from the opening slot 941 (e.g., Figure 12 (As shown by the dotted line inside), thereby releasing the locking state between the connecting piece 93 and the locking piece 94, allowing the first vertical wall 3 and the second vertical wall 4 to fold normally, and the box to return to its folded state.

[0098] Furthermore, by placing the connecting piece 93 on the second wide strip 211 and the locking piece 94 on the first vertical wall 3, the locking piece 94 is positioned below the connecting piece 93. When the box is in the unfolded state, the connecting piece 93 is within the slot 941 and is vertically oriented. In other words, in this state, the connecting piece 93 is held vertically by gravity, ensuring that it will not detach from the slot 941 during use unless manually intervened, thus guaranteeing that the box remains in the unfolded state and does not affect normal use. Only when the box needs to be folded again, by manually rotating the connecting piece 93, it disengages from the slot 941, allowing the box to fold. Moreover, the connecting structure in this application is located on the inside of the box; that is, when the box is in the unfolded state, the connecting structure is located on the inside of the box, effectively preventing accidental contact with the connecting piece 93.

[0099] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
