Description

Technical Field

[0001] This utility model belongs to the field of solid logistics transportation, specifically relating to a foldable aluminum alloy environmentally friendly logistics box. Background Technology

[0002] Logistics boxes, also widely known as turnover boxes, are indispensable tools in the logistics, warehousing, and manufacturing industries. Based on the characteristics of the goods they contain, logistics boxes can generally be divided into two main categories: solid logistics boxes and liquid logistics boxes, to meet the storage and transportation needs of different goods. Solid logistics boxes are mainly used for loading solid items, such as parts, electronic products, and clothing. Liquid logistics boxes are specifically designed for loading liquid or semi-fluid items, such as chemicals and food sauces.

[0003] Existing logistics boxes have some structural limitations. Many have an integrated front and rear panel design, allowing loading and unloading only from the top. This design restricts the flexibility of the boxes during loading and unloading, preventing operators from easily accessing or placing items from the front or rear. This not only increases the difficulty and time cost of loading and unloading operations but also affects the efficiency and safety of logistics operations.

[0004] The utility model with publication number CN216103277U discloses a logistics turnover box that is easy to stack. Although the logistics turnover box can be folded and placed to reduce the stacking height when not in use, the logistics turnover box cannot be stacked in multiple layers when loaded, nor can goods be put in or taken out during loading. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a foldable aluminum alloy environmentally friendly logistics box. The foldable aluminum alloy logistics box can realize multi-layer stacking in the loading state, and can also facilitate the placement or removal of fixed goods during loading.

[0006] The above-mentioned objective of this utility model is achieved through the following technical solution:

[0007] This utility model provides a foldable aluminum alloy environmentally friendly logistics box, including a chassis, a main door, a side door, and a top cover. The main door is divided into a front door and a rear door, and the side door is divided into a left door and a right door.

Each front door and rear door consists of an upper door and a lower door. The upper door is rotatably connected to the lower door through a main door pivot, and the lower door is bolted to the chassis. The left door and right door are respectively located on the left and right sides of the chassis. Side pillars are provided on both sides of the left door and right door. Support legs are provided on the top of the side pillars, and L-shaped baffles are provided on the support legs. The L-shaped baffles are used to fix the upper layer of logistics boxes when the logistics boxes are stacked in the loaded state. The top cover is divided into a left upper cover and a right upper cover. The left upper cover is rotatably connected to the upper side of the left door through an embedded hinge, and the right upper cover is rotatably connected to the upper side of the right door through an embedded hinge.

[0008] According to one embodiment of the present invention, the embedded hinge includes an upper hinge, an intermediate connecting member, a bolt assembly a, a bolt assembly b, and a side rotating shaft. The upper hinge is embedded in the upper cover and has a hollow cylindrical structure through which the bolt assembly a passes. The side rotating shaft is an internally hollow cylindrical structure and is fixedly installed on the upper side of the side door. The upper hinge is rotatably connected to the intermediate connecting member through the bolt assembly a, and the intermediate connecting member is rotatably connected to the side rotating shaft through the bolt assembly b.

[0009] According to one embodiment of the present invention, the chassis includes a chassis plate and supports. The chassis plate is used to support the loaded items. A front cross frame is provided on both the front and rear sides of the chassis to enhance the strength of the chassis plate. Side panels are provided on both the left and right sides of the chassis plate to raise the side doors. A side cross frame is provided on the upper edge of the side panels, and a lower side frame is provided on the lower edge of the side panels. Both the side cross frame and the lower side frame enhance the strength of the side panels. Supports are provided at both the front and rear ends of the side panels to connect the chassis, the main door, and the side doors. The supports include a chassis support, feet, a front support plate, a side support plate, and a rear support plate. The chassis support is mounted on the feet, and the front and side support plates are mounted on the rear support plate. The plate and the rear plate of the support are connected in sequence to form a U-shaped structure on the chassis support. The front plate of the support has a front plate notch on the lower side to allow the lower side frame of the chassis to pass through. The upper support foot is provided above the front plate of the support. When the logistics box is stacked in the folded state, the upper support foot is used to insert into the bottom foot of the upper layer of logistics box to fix the upper layer of logistics box. The side plate of the support has a side plate round hole to allow bolts to pass through. The rear plate of the support has a rear plate waist-shaped hole in the vertical direction to allow the side bolt of the side door to be inserted. The rear plate of the support has a U-shaped groove on the upper side to hold the round pin of the side door. After the logistics box is assembled, the front horizontal frame of the chassis is connected to the side plate of the support, and the lower side frame of the chassis passes through the front plate notch and contacts the front horizontal frame of the chassis.

[0010] According to one embodiment of the present invention, both the upper door and the lower door include a front door panel. Locks are provided on the left and right sides of the upper door and the left and right sides of the lower door, respectively. The upper door is connected to the left door and the right door through the locks, and the lower door is connected to the left door and the right door through the locks, respectively. The upper door has a main door upper horizontal frame, the upper door and the lower door have main door side frames on both sides, the upper door has a main door middle horizontal frame on the lower side, and the lower door has a main door lower horizontal frame. The main door upper horizontal frame, the main door side frame, the main door middle horizontal frame, and the main door lower horizontal frame are all used to enhance the strength of the front door panel.

[0011] According to one embodiment of the present invention, a threaded tube is provided at the position of the circular hole on the side panel corresponding to the lower door. The threaded tube is welded to the inside of the lower horizontal frame of the main door. A through hole is provided at the position of the circular hole on the side panel corresponding to the U-shaped plate of the chassis. After the logistics box is assembled, the bolt passes through the circular hole and the through hole of the side panel and is screwed into the threaded tube, so that the lower door is rotated and connected to the chassis by the bolt.

[0012] According to one embodiment of the present invention, the lock includes a lock piece a, a bolt handle, a bolt, a lock piece b, and a lock panel. The lock panel is fixed to the front door panel by rivets. Lock pieces a and b are fixedly provided on the lock panel. The bolt can slide between lock pieces a and lock pieces b. The bolt is fixedly connected to the bolt handle. The side pillar of the side door is provided with a lock hole for the bolt to be inserted.

[0013] According to one embodiment of this utility model, both the left and right doors include side door panels. An upper side horizontal frame is provided on the upper side of the side door panel, and a side pivot is provided on the upper side horizontal frame for rotatably connecting the upper cover. A lower side horizontal frame is provided on the lower side of the side door panel. After the logistics box is assembled, the lower side horizontal frame of the side door is located above the chassis side horizontal frame of the chassis. Both the upper and lower side horizontal frames are used to enhance the strength of the side door panel. Side columns are provided on both sides of the side door panel, with the lower end of the side column longer than the side door panel. After the logistics box is assembled, the lower end of the side column is inserted into the support. A round pin is provided on the outer side of the side column corresponding to the U-shaped groove position, and a side bolt is provided on the outer side of the side column corresponding to the waist-shaped hole position of the rear plate. When the round pin falls into the U-shaped groove and the side bolt is inserted into the waist-shaped hole of the rear plate, the side door is fixed.

[0014] According to one embodiment of the present invention, the support further includes a U-shaped chassis plate, which is located inside the U-shaped structure with its opening facing downwards. After the logistics box is assembled, the U-shaped chassis plate is located above the front horizontal frame of the chassis, and the side pillars of the side door rest on the upper surface of the U-shaped chassis plate. The lower horizontal frame of the main door is close to the side of the U-shaped chassis plate, so that the bottom surface of the side pillar is higher than the lower horizontal frame of the main door, thereby making the side bolts located above the threaded pipe, so that the side door and the main door will not interfere with each other during installation and disassembly.

[0015] According to one embodiment of this utility model, the upper left cover includes an upper panel a. A buckle is provided on the upper right side surface of the upper panel a. An upper cover side plate is fixedly provided on the lower left side surface of the upper panel a to prevent excessive rotation of the upper left cover. An upper hinge is fixedly connected to the upper cover side plate. Upper cover fixing frames are fixedly provided on both the front and rear lower surfaces of the upper panel a. An upper cover side plate is fixedly provided on the lower right side surface of the upper panel a. The upper cover fixing frame, upper cover side plate, and upper cover side plate are all L-shaped plates, each fixed to the lower surface of the upper panel a by a rivet on one side, and the other side is perpendicular to the [missing information - likely a typo]. The upper left cover is located near the inner side of the upper left cover. The upper cover support tube is fixedly connected to the upper cover fixing frame and the upper cover side plate. The upper cover support plate is fixedly connected to the upper cover fixing frame and the upper cover side plate. The upper cover middle tube is fixedly connected to the upper cover side plate and the upper cover side plate. The upper cover support tube, upper cover support plate and upper cover middle tube are all used to enhance the strength of the upper panel a. The upper right cover includes the upper panel b. The upper panel b has a hook on the left side. The buckle and the hook can be used to lock and fix the upper left cover and the upper right cover. The structure of the lower surface of the upper panel b is the same as the structure of the lower surface of the upper panel a.

[0016] According to one embodiment of the present invention, the chassis plate, front door plate, side door plate, upper panel a, and upper panel b are all PP hollow plates, the bolts, rivets, side bolts, bolt assembly a, and bolt assembly b are made of carbon steel, the lock is made of polyurethane, and the other components are made of aluminum alloy.

[0017] The advantages of this utility model compared with the existing technical solutions are:

[0018] 1. This utility model enables convenient placement or removal of fixed goods during loading. By designing both the front and rear doors as upper and lower doors, and since the upper door is rotatably connected to the lower door via a main door hinge, the upper door can also rotate outwards during loading. This creates a passage connecting the inside of the logistics box to the outside at the original upper door location, allowing staff to place or remove fixed goods through the upper passage of the front and rear doors during loading.

[0019] 2. This utility model enables multi-layer stacking of logistics boxes while they are loaded. Since the top cover is connected to the upper side of the side door via an embedded hinge, and since the embedded hinge has no protrusion, it will not push up the upper layer of logistics boxes when they are stacked while loaded, thus ensuring the stability of the logistics boxes when they are stacked in multiple layers while loaded.

[0020] 3. This utility model ensures the stability of multi-layer stacking of logistics boxes. The utility model has support legs above the side columns, and L-shaped baffles are installed on the support legs. When multiple layers of logistics boxes are stacked, the L-shaped baffles can limit the relative displacement of the logistics boxes, thereby ensuring the stability of multi-layer stacking.

[0021] 4. This utility model achieves lightweight and safe logistics boxes. Since the supporting force of traditional supporting components is positively correlated with weight, strong supporting capacity often leads to excessively heavy boxes. However, in this utility model, the chassis plate, front panel, and door panel components are all made of environmentally friendly PP hollow board, while other major components are made of aluminum alloy, which can greatly reduce the overall weight of the box while ensuring strength.

[0022] 5. In this invention, the bottom edges of the main door and the side door are not at the same height. This means that during installation and disassembly, the main connecting parts of the side door and the base are not at the same height. Therefore, when folding, after the main door has landed on the base plate, the side door, because its bottom edge is higher than the main door, will fold and land on top of the main door, allowing the side door and main door to fold tightly together. If the bottom edges of the main door and side door were not at the same height, they would obstruct each other during folding, preventing the logistics box from folding or making the folded logistics box unstable when stacked.

[0049] Example 1

[0050] like Figure 1-22 As shown, this embodiment provides a foldable aluminum alloy environmentally friendly logistics box, see reference. Figure 1 It includes chassis 1, main door, side door, and top cover. The main door is divided into front door 2 and rear door 6, and the side door is divided into left door 3 and right door 7. The chassis 1, front door 2, rear door 6, left door 3, right door 7, and top cover can form a box.

[0051] refer to Figure 2 The chassis 1 includes a chassis plate 13 and a support 11. The chassis plate 13 is used to support the loaded items. The chassis 1 is provided with a front crossbeam 16 on both the front and rear sides. Figure 2 The chassis front cross frame 16 (not shown) is used to enhance the strength of the chassis plate 13. Chassis side panels 12 are provided on the left and right sides of the chassis plate 13. The chassis side panels 12 are used to raise the side door so that the bottom edge of the side door is not at the same height as the main door. Thus, when the logistics box is folded, after the main door has landed on the chassis plate 13, the side door, because its bottom edge is higher than the main door, will land on top of the main door after folding. The side door and the main door are tightly folded. Chassis side cross frame 17 is provided on the upper side of the chassis side panel 12, and chassis side lower frame 19 is provided on the lower side of the chassis side panel 12. Both chassis side cross frame 17 and chassis side lower frame 19 are used to enhance the strength of the chassis side panel 12. Supports 11 are provided at the front and rear ends of the chassis side panel 12. The supports 11 are used to connect the chassis 1, the main door and the side door.

[0052] refer to Figure 2 , Figure 7 , Figure 8 and Figure 9 The support 11 includes a chassis support 14, a base 18, a front support plate 111, a side support plate 112, and a rear support plate 113. The chassis support 14 is mounted on the base 18. When stacking logistics boxes in their loaded state, the base 18 will be placed on top of the support feet 72 of the next layer of logistics boxes. (See base 72 for details.) Figure 1 and Figure 4When stacking logistics boxes in their folded state, the bottom feet 18 will be placed above the upper support feet 118 of the next layer of logistics boxes. The front support plate 111, the side support plate 112, and the rear support plate 113 are connected in sequence to form a U-shaped structure on the chassis support 14. The front support plate 111 has a front plate notch 114 on its lower side to allow the chassis side lower frame 19 to pass through. The upper support foot 118 is located above the front support plate 111. (See reference) Figure 21 and Figure 22 When the logistics boxes are stacked in the folded state, the upper support leg 118 is inserted into the bottom leg 18 of the upper layer logistics box to secure the upper layer logistics box. (See reference) Figure 21 , Figure 22 .

[0053] refer to Figure 7 , Figure 9 and Figure 13 The support side plate 112 has a side plate circular hole 115 for allowing the bolt 8 to pass through. The support rear plate 113 has a rear plate waist-shaped hole 116 in the vertical direction for allowing the side bolt 77 of the side door to be inserted, thereby restricting the displacement of the side door. The support rear plate 113 has a U-shaped groove 117 on the top for locking the round pin 76 of the side door. The U-shaped groove 117 cooperates with the rear plate waist-shaped hole 116, allowing the side bolt 77 of the side door to be inserted into the rear plate waist-shaped hole 116. When the round pin 76 of the side door falls into the U-shaped groove 117, the side door is fixed. After the logistics box is assembled, the chassis front cross frame 16 is connected to the support side plate 112, and the chassis lower side frame 19 passes through the front plate notch 114 and contacts the chassis front cross frame 16. Figure 9 .

[0054] The support 11 also includes a chassis U-shaped plate 15, which is located inside the U-shaped structure with its opening facing downwards. After the logistics box is assembled, the chassis U-shaped plate 15 is located above the front horizontal frame 16 of the chassis. The side pillars 71 of the side door rest on the upper surface of the chassis U-shaped plate 15, and the lower horizontal frame 28 of the main door is close to the side of the chassis U-shaped plate 15, so that the bottom of the side pillars 71 is higher than the lower horizontal frame 28 of the main door. This makes the side bolts 77 located above the threaded tube 27. Since the side door is installed on the base by the side bolts 77, and the main door is fixed to the base 1 by the bolts 8 screwed into the threaded tube 27, the side bolts 77 are located above the threaded tube 27. That is, the side door and the main door are not at the same height as the main connecting parts of the base 1 during installation and disassembly, so that the side door and the main door will not interfere with each other during installation and disassembly.

[0055] refer to Figure 1 , Figure 3 and Figure 9The front door 2 and the rear door 6 are respectively located at the front and rear of the chassis 1. The front door 2 and the rear door 6 have the same structure, each consisting of an upper door and a lower door. Both the upper door and the lower door include a front door panel 22. The upper door is rotatably connected to the lower door through the main door pivot 26, and the lower door is connected to the chassis 1 by bolts 8.

[0056] Specifically, locks 21 are provided on the left and right sides of the upper door and the left and right sides of the lower door. The upper door is connected to the left door 3 and the right door 7 respectively through locks 21. When only the lock 21 of the upper door is released, the upper door can be opened by rotating around the main door pivot 26 without opening the lower door. The lower door is connected to the left door 3 and the right door 7 respectively through locks 21. When the locks 21 of the upper door and the lower door are released at the same time, the lower door can be folded onto the chassis 1 by rotating around the bolt 8.

[0057] refer to Figure 3 The upper side of the upper door is provided with a main door upper horizontal frame 23, the upper and lower doors are respectively provided with main door side frames 24, the lower side of the upper door is provided with a main door middle horizontal frame 25, and the lower side of the lower door is provided with a main door lower horizontal frame 28. After the logistics box is assembled, the main door lower horizontal frame 28 is placed above the chassis front horizontal frame 16 of the chassis 1. The main door upper horizontal frame 23, main door side frame 24, main door middle horizontal frame 25, and main door lower horizontal frame 28 are all used to enhance the strength of the front door panel 22.

[0058] refer to Figure 9 A threaded tube 27 is provided at the position of the circular hole 115 on the side panel corresponding to the lower door. The threaded tube 27 is welded to the inside of the lower horizontal frame 28 of the main door. A through hole 151 is provided at the position of the U-shaped plate 15 on the chassis corresponding to the circular hole 115 on the side panel. After the logistics box is assembled, the bolt 8 passes through the circular hole 115 and the through hole 151 on the side panel and is screwed into the threaded tube 27, so that the lower door is rotatably connected to the chassis 1 by the bolt 8.

[0059] refer to Figure 10 and Figure 11 The lock 21 includes a lock a211, a bolt handle 212, a bolt 213, a lock b214, and a lock panel 215. The lock panel 215 is fixed to the front door panel 22 by rivets 10. Lock a211 and lock b214 are fixedly mounted on the lock panel 215. The bolt 213 can slide between lock a211 and lock b214. The bolt 213 is fixedly connected to the bolt handle 212. The side pillar 71 of the side door is provided with a lock hole for the bolt 213 to be inserted. The operator moves the bolt handle 212 to drive the bolt 213 to be inserted into the lock hole.

[0060] refer to Figure 1 , Figure 4 and Figure 20Left door 3 and right door 7 are respectively located on the left and right sides of chassis 1. Left door 3 and right door 7 have the same structure. Both left door 3 and right door 7 are provided with side columns 71. Support legs 72 are provided above the side columns 71. Support legs 72 are used to place the bottom foot 18 of another logistics box when stacking in the loading state of the logistics box. L-shaped baffles are provided on the support legs 72. L-shaped baffles are used to fix the upper layer of logistics box when stacking in the loading state of the logistics box.

[0061] refer to Figure 1 , Figure 4 , Figure 12 and Figure 13 Both the left door 3 and the right door 7 include a side door panel 75. An upper side horizontal frame 74 is provided on the upper side of the side door panel 75, and a side pivot 73 is provided on the upper side horizontal frame 74. The side pivot 73 is used to rotatably connect to the upper cover. A lower side horizontal frame 78 is provided on the lower side of the side door panel 75. After the logistics box is assembled, the lower side horizontal frame 78 of the side door is located above the chassis side horizontal frame 17 of the chassis 1. Both the upper side horizontal frame 74 and the lower side horizontal frame 78 are used to enhance the strength of the side door panel 75. Side pillars 71 are provided on both sides of the side door panel 75. The lower end of the side pillars 71 is longer than the side door panel 75. (Note: The last sentence appears to be incomplete and possibly refers to a different topic.) Figure 13 After the logistics box is assembled, the lower end of the side column 71 is inserted into the support 11. A round pin 76 is provided on the outer side of the side column 71 corresponding to the U-shaped groove 117, and a side bolt 77 is provided on the outer side of the side column 71 corresponding to the waist-shaped hole 116 of the rear plate.

[0062] refer to Figure 7 , Figure 9 , Figure 12 and Figure 13 When the round pin 76 falls into the U-shaped groove 117 and the side bolt 77 is inserted into the waist-shaped hole 116 of the rear plate, the side door is fixed in place. When the logistics box is folded, the side door is lifted, the round pin 76 leaves the U-shaped groove 117, while the side bolt 77 remains inserted into the waist-shaped hole 116 of the rear plate and slides vertically within the waist-shaped hole 116 of the rear plate. At this time, the side door rotates around the side bolt 77.

[0063] refer to Figure 5 and Figure 6 The upper cover is divided into a left upper cover 4 and a right upper cover 5. The left upper cover 4 is rotatably connected to the upper side of the left door 3 through an embedded hinge 9, and the right upper cover 5 is rotatably connected to the upper side of the right door 7 through an embedded hinge 9.

[0064] refer to Figure 4 , Figure 14 and Figure 15The embedded hinge 9 includes an upper hinge 41, an intermediate connector 91, bolt assembly a92, bolt assembly b93, and a side pivot 73. The upper hinge 41 is embedded in the upper cover and has a hollow cylindrical structure through which the bolt assembly a92 passes. The side pivot 73 is an internally hollow cylindrical structure and is fixedly mounted on the upper side of the side door. The upper hinge 41 is rotatably connected to the intermediate connector 91 via bolt assembly a92, and the intermediate connector 91 is rotatably connected to the side pivot 73 via bolt assembly b93.

[0070] This embodiment describes the specific method of using the logistics box described in this utility model.

[0071] When it is necessary to assemble the logistics box described in this utility model, the steps are as follows:

[0072] 1. Assemble the chassis.

[0073] 2. Place the left door 3 on the left side of the chassis 1 and insert the side bolt 77 into the waist-shaped hole 116 of the rear plate.

[0074] 3. Lower the left door 3. Specifically, place the side pillar 71 of the left door 3 on the U-shaped plate 15 of the chassis, so that the round pin 76 falls into the U-shaped groove 117. At this time, the lower side frame 78 of the left door 3 is located above the chassis side frame 17 of the chassis 1. The installation of the left door 3 is complete.

[0075] 4. The installation of the right side door 7 is completed in the same way as the left side door 3.

[0076] 5. Place the front door 2 in front of the chassis 1. Specifically, place the lower horizontal frame 28 of the main door of the front door 2 above the front horizontal frame 16 of the chassis, and screw the bolt 8 through the round hole 115 and through hole 151 of the side panel into the threaded tube 27.

[0077] 6. Move the latch handle 212 on the front door 2 so that the latch 213 is fully inserted into the lock hole on the side pillar 71, and the front door 2 is installed.

[0078] 7. The installation of rear door 6 is carried out in the same manner as front door 2.

[0079] 8. Place the upper left cover 4 on the upper side of the left door 3, rotatably connect the upper hinge 41 to the middle connector 91 through bolt assembly a92, and rotatably connect the middle connector 91 to the side pivot 73 through bolt assembly b93, thereby completing the splicing of the embedded hinge 9.

[0080] 9. Rotate the upper left cover 4 so that the upper left cover 4 covers the top of the logistics box.

[0081] 10. Similarly, assemble the upper right cover 5 and the upper left cover 4 to complete the assembly of the inner hinge 9 of the upper right cover 5, so that the upper right cover 5 also covers the top of the logistics box.

[0082] 11. Fasten buckle 43 and hook 46 to complete the assembly of the logistics box.

[0085] 2. For example Figure 18 As shown, open all the locks 21 of the front door 2, rotate the lower door of the front door 2 into the housing until the lower door of the front door 2 is completely parallel to the chassis 1, and then rotate the upper door of the front door 2 to overlap the lower door of the front door 2.

[0086] 3. Open all the locks 21 of the rear door 6, rotate the lower door of the rear door 6 into the box until the lower door of the rear door 6 is completely parallel to the chassis 1, and then rotate the upper door of the rear door 6 to overlap the lower door of the rear door 6.

[0087] 4. Lift the left side door 3 so that the round pin 76 disengages from the U-shaped groove 117. At this time, the left side 3 can rotate around the side bolt 77. Rotate the left side 3 until the left side 3 is completely parallel to the chassis 1.

[0088] 5. Similarly, lift the right side panel 7, and then rotate the right side panel 7 until the right side panel 7 is completely parallel to the chassis 1.

[0089] 6. For example Figure 16 As shown, the present invention is in a fully folded state at this time.

[0090] When it is necessary to stack the logistics boxes described in this utility model in their loaded state, such as Figure 19 and Figure 20 As shown, simply place the bottom foot 18 of the upper logistics box on the support foot 72 of the lower logistics box, ensuring that each bottom foot 18 is on the upper side of the support foot 72 and on the outside of the L-shaped baffle.
