Description

Technical Field

[0001] This utility model relates to the field of material transport containers, and in particular to a foldable transport box. Background Technology

[0002] Existing transport boxes for transporting shaft parts are generally wooden transport boxes. For a specific structure, please refer to Chinese Patent No. CN210213131U, which discloses a wooden transport box for packaging and transporting tractor component wheel axle frames. The box includes a box body, which includes a pallet set at the bottom. A pair of side panels and a pair of end panels are erected on the four sides of the pallet. A cover plate parallel to the pallet is mounted on the side panels and end panels. The pallet, side panels, end panels and cover plates are all fixedly connected by pins. The box body is provided with parallel and spaced placement racks. Each placement rack has a spaced groove for placing and limiting shaft parts.

[0003] When assembling the aforementioned transport crates, the bottom of each side panel and end panel needs to be nailed to the side wall of the pallet with pins. Then, a cover plate is placed on top of the side panels and end panels, and pins are driven through the cover plate and nailed into the sides of the side panels and end panels for fixation. The entire assembly process is time-consuming and labor-intensive. Considering that the transport crates are large in size and take up a lot of space after assembly, they are generally not pre-assembled for storage. They are only assembled in time before the parts are transported, which leads to a longer delivery cycle and slower delivery speed. Utility Model Content

[0004] In view of the shortcomings of existing shipping boxes, such as inconvenience in storage and the need for immediate assembly at the time of shipment, which leads to extended delivery cycles and slow delivery speeds, the purpose of this utility model is to provide a shipping box that can be folded to reduce its volume for easy storage.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A collapsible transport container includes a pallet, with surrounding barriers and a top cover that cooperates with the barriers. The surrounding barriers include:

[0007] The first baffle assembly is symmetrically arranged on both sides of the tray and can be unfolded and flipped to stand upright on both sides of the tray or folded in half and flipped to a horizontal state.

[0008] The second baffle assembly is disposed on the adjacent side of the first baffle assembly and can be flipped to stand upright on both sides of the tray or flipped to be parallel to the tray and stacked on the folded first baffle assembly;

[0009] A limiting mechanism is used to restrict the rotation of the first baffle assembly and the second baffle assembly respectively when they are erected;

[0010] The top cover is mounted on the first baffle assembly and the second baffle assembly in the upright position.

[0011] Using the above solution, the shipping box can be folded for storage. When folding, the first baffle assembly can be folded in half and flipped to a horizontal position. Then, the second baffle assembly is flipped and stacked on top of the horizontal first baffle assembly, and the top cover is stacked on top of the second baffle assembly. This folding method significantly reduces the volume of the shipping box, and the shipping boxes can be stacked and stored together, alleviating the problem of existing shipping boxes being too bulky to store. When shipping, the shipping box only needs to be unfolded, and the first and second baffle assemblies are stabilized in an upright position by the limiting structure. Compared with the existing shipping boxes that need to be assembled on-site and fixed with pins, the unfolding step of the shipping box in this solution is faster and easier, which can shorten the shipping time, speed up the process, and reduce manpower consumption.

[0012] Preferably, a first mounting bracket is symmetrically arranged on both sides of the tray. The first baffle assembly includes a lower baffle movably connected between the first mounting brackets and an upper baffle hinged to the lower baffle on the side away from the tray. A second mounting bracket is arranged at both ends of the first mounting bracket. The second baffle assembly includes a straight baffle located above the first mounting bracket and movably connected between the second mounting brackets.

[0013] Using the above solution, the upper and lower baffles are hinged. When loading, the lower baffle can be erected first, while the upper baffle is folded in half. At this time, the lower baffle is lower, so loading can be done from there first. After the goods are piled up, the upper baffle can be unfolded. This avoids the problem of the upper baffle being too high from the pallet, making loading inconvenient.

[0014] Preferably, the lower baffle has first connecting posts protruding on both sides, and the first mounting bracket has first sliding holes for the first connecting posts to be inserted to achieve rotation and vertical sliding. The limiting mechanism includes first limiting posts protruding on the straight baffle and first limiting grooves on both sides of the lower baffle. When the straight baffle is upright, the first limiting grooves align and engage with the first limiting posts as the lower baffle tends to rotate and move upward. Subsequently, the lower baffle moves downward to lock the opening of the first limiting grooves in a misaligned position with the first limiting posts.

[0015] Using the above solution, the structure is mainly used to support the flipping of the lower baffle and limit its vertical position. To achieve the above-mentioned limiting, only three actions are needed during the process of flipping the lower baffle to the vertical position: lifting the lower baffle, aligning the first limiting post and the first limiting groove, and lowering the lower baffle. Folding is even simpler; simply lift the lower baffle and flip it downwards, and the first limiting post will disengage from the first limiting groove. In this solution, the folding and verticalizing actions of the lower baffle are very smooth, requiring no operation of other parts, thus simplifying the process of unfolding the transport box.

[0016] Preferably, the second mounting bracket extends with a mating protrusion that abuts against the lower baffle in the upright state, the side of the first connecting column facing away from the limiting plate abuts against one side of the first sliding hole, the first sliding hole is provided with a relief groove for the first connecting column to move and avoid during the flipping of the lower baffle, and the relief groove is provided with a mating protrusion that restricts the horizontal movement of the first connecting column from leaving the relief groove.

[0017] Using the above solution, the structure in this solution is mainly used to restrict the horizontal movement of the lower baffle. The principle is that the contact between the limiting plate and the lower baffle, and the contact between the first connecting post and the side wall of the first sliding hole, restrict the movement of the lower baffle from two directions respectively. When the lower baffle is released from the flipping limit, the horizontal limit in this solution will also be released. Specifically, when the lower baffle is lifted upward, the first connecting post will align with the clearance groove. When the lower baffle is flipped downward, the first connecting post will move into the clearance groove, thus releasing the restriction on the horizontal movement of the lower baffle. Therefore, this solution achieves the restriction and release of the horizontal movement of the lower baffle without changing the folding action of the lower baffle, further increasing the stability of the transport box after it is unfolded.

[0018] Preferably, the locking assembly includes a handle that is rotatable and laterally slidable on the upper baffle, and a latch fixedly mounted on the straight baffle to prevent the handle from disengaging after the end of the handle is inserted.

[0019] Using the above solution, once the upper baffle is erected, simply insert the handle into the latch and rotate it at a certain angle to engage with the latch. The entire operation is simple and easy to understand, and its structure is similar to that of traditional door locks, making it easy to manufacture and reducing production costs.

[0020] Preferably, the straight baffle is provided with limiting tubes on both sides to restrict the horizontal movement of the top cover when the straight baffle is upright. The limiting tubes are detachably provided with limiting components to restrict the vertical detachment of the cover. The limiting components include an operating block protruding from the opening of the limiting tube and a limiting plug located inside the limiting tube. The end face of the operating block abuts against the top cover. The limiting plug is made of rubber or polyurethane and its outer wall is elastically press-fitted into the inner wall of the limiting tube.

[0021] Preferably, the limiting mechanism includes second limiting posts protruding on both sides of the upper baffle, an opening groove on the limiting tube for the limiting posts to flip into, and a limiting plate on the limiting member, wherein the limiting plate is provided with a slot for restricting the second limiting posts from disengaging from the opening groove.

[0022] Using the above solution, the limiting component can simultaneously restrict the top cover from detaching and the upper baffle from flipping. Compared with the locking component in the previous solution, it reduces the operation of the handle, which can speed up the unfolding and folding of the transport box. Furthermore, the entire structure is hidden in the limiting tube frame, making the appearance of the transport box cleaner and simpler.

[0023] Preferably, the straight baffle has second connecting posts protruding on both sides, and the second mounting bracket has second sliding holes for the second connecting posts to be inserted to achieve rotation or vertical sliding. The limiting mechanism includes limiting blocks protruding on both sides of the straight baffle and a second limiting groove opened on the top of the second mounting bracket. The limiting blocks rotate to stand upright and slide upwards to align with the second limiting groove as the straight baffle rotates, and engage with the second limiting groove as the straight baffle slides downwards.

[0024] Using the above scheme, the limiting block can restrict the flipping and horizontal movement of the straight baffle after it is engaged with the second limiting groove. The operation steps for erecting the straight baffle are similar to those for erecting the lower baffle, which is relatively simple and easy to learn.

[0025] Preferably, the tray is provided with a placement rack for placing parts, and the opposite sides of the first baffle assembly are respectively formed with grooves for the placement rack to slide and engage.

[0026] Using the above solution, the chute can prevent the placement rack from moving horizontally, and also make the stacking of the placement rack more convenient and the stacking of parts more stable. When the lower baffle is in a horizontal state, the chute acts as a structure supporting the lower baffle and abuts against the pallet. At this time, the first connecting column is exactly located within the height range of the clearance groove.

[0027] This utility model, by adopting the above technical solution, has significant technical effects: the transport box in this solution can be folded and stored, and the first baffle assembly and the second baffle assembly can be stacked together. This folding method greatly reduces the volume of the transport box, and the transport boxes can be stacked and stored together, alleviating the problem of existing transport boxes being too bulky to store. When shipping, the transport box only needs to be unfolded, and the first baffle assembly and the second baffle assembly are stabilized in an upright state by means of the limiting structure. Compared with the existing transport boxes that need to be assembled on-site and fixed with pins, the unfolding step of the transport box in this solution is faster and easier than the existing transport box assembly step, which can shorten the shipping time, speed up the process, and reduce manpower consumption.

Detailed Implementation

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0044] Example 1

[0045] A foldable transport box, according to Figure 1 , 2 As shown, the device includes a tray 1, with first mounting brackets 3 symmetrically arranged on both sides of the tray 1. A lower baffle 4 is movably connected between the first mounting brackets 3. First connecting posts 8 protrude from both sides of the lower baffle 4. The first mounting brackets 3 have first sliding holes 9 for the first connecting posts 8 to be inserted, allowing for rotation and vertical sliding. An upper baffle 5 is hinged to the side of the lower baffle 4 away from the tray 1. Figure 3 As shown, a hinge structure 27 is provided between the upper baffle 5 and the lower baffle 4. A placement rack 25 for placing parts is provided on the tray 1. Slide grooves 26 are formed on opposite sides of the lower baffle 4 and the upper baffle 5 to guide and slide the placement rack 25 into place. According to... Figure 1 , 4 As shown, a second mounting bracket 6 is provided at both ends of the first mounting bracket 3, and a straight baffle 7 is provided above the first mounting bracket 3. A second connecting post 21 protrudes from both sides of the straight baffle 7. A second sliding hole 22 is provided on the second mounting bracket 6 so that the second connecting post 21 can be inserted to achieve rotation or vertical sliding.

[0046] The lower baffle 4, upper baffle 5, and straight baffle 7 are kept upright by a limiting mechanism, according to Figure 2 , 3 As shown in Figure 8, the limiting mechanism includes a first limiting post 10 protruding from the straight baffle 7, and first limiting grooves 11 on both sides of the lower baffle 4. When the straight baffle 7 is upright, the first limiting grooves 11 align and engage with the first limiting post 10 as the lower baffle 4 tends to rotate and move upward. Subsequently, the lower baffle 4 moves downward, causing the opening of the first limiting groove 11 to be misaligned and locked with the first limiting post 10. Figure 1 , 4 As shown, the limiting mechanism also includes limiting blocks 23 protruding on both sides of the straight baffle 7. The top of the second mounting bracket 6 is provided with a second limiting groove 24. The limiting blocks 23 rotate to stand upright and slide upwards with the straight baffle 7 to cross and align with the second limiting groove 24. As the straight baffle 7 slides downwards, the limiting blocks 23 engage with the second limiting groove 24 for limiting.

[0047] according to Figure 2 , 4 As shown, the second mounting bracket 6 extends with a mating protrusion 12 that abuts against the lower baffle 4 in the upright state. The side of the first connecting column 8 facing away from the limiting plate 20 abuts against the side of the first sliding hole 9. The first sliding hole 9 is provided with a relief groove 13 that allows the first connecting column 8 to move and avoid during the flipping of the lower baffle 4.

[0048] according to Figure 5As shown, a handle 14 is provided on the upper baffle 5. The handle 14 can rotate and slide laterally. A latch 15 is fixedly provided on the straight baffle 7 to prevent the handle 14 from disengaging after the end of the handle 14 is inserted. In this embodiment, a sleeve 28 is fixedly provided on the upper baffle 5 to allow the handle 14 to slide and rotate.

[0049] according to Figure 6 , 7 As shown, the straight baffle 7 has protruding limiting tube frames 16 on both sides to restrict the horizontal movement of the top cover 2 when the straight baffle 7 is upright. The top cover 2 has notches 201 at the four corners to avoid the limiting tube frames 16. The limiting tube frame 16 is detachably provided with a limiting member 17 to restrict the vertical disengagement of the cover plate. The limiting member 17 includes an operating block 1701 exposed outside the opening of the limiting tube and a limiting plug 1702 located inside the limiting tube. The end face of the operating block 1701 abuts against the top cover 2. The limiting plug 1702 is made of rubber or polyurethane and its outer wall is elastically press-fitted into the inner wall of the limiting tube frame 16.

[0050] Based on the above structure, refer to Figures 1-11 It can be seen that the unfolding process of the transport box in this embodiment is as follows:

[0051] The first step is to erect the straight baffle 7. First, flip the straight baffle 7 upwards, then lift it up so that the limiting block 23 exceeds the second limiting groove 24, and flip the straight baffle 7 to the upright position. Finally, put down the straight baffle 7 to complete the vertical positioning.

[0052] The second step is to erect the lower baffle 4. First, flip the lower baffle 4 upward. During this process, lift the lower baffle 4 upward until the opening of the first limiting groove 11 is aligned with the first limiting post 10. Then continue to flip the lower baffle 4 upward. When it is fully erected, put the lower baffle 4 down. At this time, the opening of the first limiting post 10 is misaligned with the opening of the first limiting groove 11 and is locked in the first limiting groove 11.

[0053] The third step is to unfold the upper baffle 5, flip the upper baffle 5 upward to the upright position, and then operate the handle 14 to insert into the latch 15 and rotate it at a certain angle to achieve the latching with the latch 15.

[0054] The fourth step is to place the top cover 2, align the notches 201 at the four corners of the top cover 2 with the limiting tube frame 16 and put it down, then install the limiting piece 17, at which point the transport box is fully unfolded.

[0055] The shipping box in this embodiment can be folded for storage. When folding, the first baffle assembly can be folded in half and flipped to a horizontal state. Then, the second baffle assembly is flipped and stacked on top of the horizontal first baffle assembly, and the top cover 2 is stacked on top of the second baffle assembly. This folding method significantly reduces the volume of the shipping box, and the shipping boxes can be stacked and stored together, alleviating the problem of existing shipping boxes being too bulky to store. When shipping, the shipping box only needs to be unfolded, and the first and second baffle assemblies are stabilized in an upright state by the limiting structure. Compared with the existing shipping boxes that need to be assembled on-site and fixed with pins, the unfolding step of the shipping box in this solution is faster and easier than the existing shipping box assembly step, which can shorten the shipping time, speed up the process, and reduce manpower consumption.

[0056] Example 2

[0057] Based on Embodiment 1, this embodiment further defines a foldable transport box, according to... Figures 12-14 As shown, the limiting mechanism includes second limiting posts 18 protruding from both sides of the upper baffle 5, an opening groove 19 for the limiting post to flip into the limiting tube, a limiting plate 20 disposed on the limiting member 17, and a slot 2001 for limiting the second limiting post 18 to disengage from the opening groove 19. In this embodiment, the operating block 1701, the limiting plug 1702 and the connecting plate are connected by bolts 29.

[0058] In this solution, it is only necessary to align the slot 2001 on the limiting plate 20 with the approximate position of the second limiting post 18 before inserting the limiting member 17 into the limiting tube bracket 16, and then make fine adjustments during insertion to make the limiting plate 20 engage with the second limiting post 18.

[0059] The limiting component 17 in this solution can simultaneously restrict the top cover 2 from detaching and restrict the upper baffle 5 from flipping. Compared with the locking component in Embodiment 1, it reduces the movement of the operating handle 14, which can speed up the unfolding and folding speed of the transport box. Furthermore, the entire structure is hidden in the limiting tube frame 16, making the appearance of the transport box neater and simpler.

[0060] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
