[0002] Collapsible boxes, as a standardized logistics carrier, are widely used in warehousing and transportation. Their core function is to protect goods and improve turnover efficiency. Currently, most collapsible boxes on the market are manufactured using processes such as blow molding, vacuum forming, injection molding, and die casting, and their structural designs are constantly evolving. However, existing technologies still suffer from insufficient structural stability: when traditional nine-legged collapsible boxes are stacked for transportation, the weight of the upper layer of goods is directly transferred to the top cover of the lower collapsible box through the bottom legs, which can easily lead to deformation or even cracking of the top cover and collapsible panels, especially under heavy-load or long-distance transportation scenarios where the risk of failure is significant.

[0043] Figure 1 A structural schematic diagram of the enclosure box 1 is shown. Figure 2 A partial cross-sectional view of the stacked upper and lower enclosure boxes 1 is shown.

[0044] Reference Figure 1 The enclosure box 1 of this application includes a base 12, a top cover 11, and enclosure panels 13.

[0045] The enclosure 13 is disposed between the bottom support 12 and the top cover 11, and the interior of the enclosure 13 forms a loading space 131 that runs vertically through the space for loading goods.

[0046] The top cover 11 is placed over the enclosure 13 to seal the top opening of the loading space 131. The top surface of the top cover 11 has multiple positioning grooves 111, spaced apart along the outer perimeter of the top cover 11. The top of the side wall of the top cover 11 near the outer edge of the positioning grooves 111 forms a support surface 112, which faces upwards and is located directly above the enclosure 13. The bottom of the top cover 11 abuts against the enclosure 13 corresponding to the support surface 112. Here, "outside" actually refers to a horizontal direction outside the enclosure box 1, and "inside" actually refers to a horizontal direction inside the enclosure box 1.

[0047] The base support 12 is located at the bottom of the enclosure 13 and seals the bottom opening of the loading space 131. The bottom surface of the base support 12 is provided with multiple feet 121 spaced apart. Each foot 121 corresponds vertically to a positioning groove 111. The bottom of each foot 121 is recessed vertically to the support surface 112, forming a stepped surface 122. That is, the stepped surface 122 formed by a portion of the bottom of the foot 121 being recessed upwards is higher than the bottom surface of the foot 121.

[0048] Reference Figure 2 During dynamic load stacking and transportation, the bottom feet 121 of the upper cofferdam 1 are positioned one-to-one within the positioning grooves 111 of the lower cofferdam 1, thus positioning the upper and lower cofferdam 1. The bottom surfaces of the bottom feet 121 abut against the bottom surfaces of the positioning grooves 111. Furthermore, the stepped surfaces 122 of the bottom feet 121 of the upper cofferdam 1 can overlap the support surfaces 112 of the lower cofferdam 1, allowing the overall weight of the upper cofferdam 1 to be vertically transferred to the bottom cofferdam 13 via the support surfaces 112 on the top cover 11 of the lower cofferdam 1. The bottom cofferdam 13 provides some support, optimizes the load transfer path, prevents the weight of the upper cofferdam 1 from directly pressing onto the top cover 11 of the lower cofferdam 1, reduces deformation and cracking caused by concentrated pressure on the top cover 11, and improves the structural strength of the cofferdam 13 and the entire cofferdam 1. In addition, the bottom foot 121 of the upper cofferdam 1 can simultaneously rest on the support surface 112 of the lower cofferdam 1 and the bottom surface of the positioning groove 111, thereby improving the stacking stability of the cofferdam 1.

[0049] Figure 3 A partial schematic diagram of the top cover 11 is shown.

[0050] Reference Figure 1 and Figure 3The top cover 11 is a rectangular cover structure. The top cover 11 can be placed over the top opening of the enclosure 13. The top surface of the top cover 11 has multiple positioning grooves 111. The positioning grooves 111 include outer peripheral positioning grooves 111 and central positioning grooves 111. The top surface of the top cover 11 has eight outer peripheral positioning grooves 111 that fit against its outer perimeter, one outer peripheral positioning groove 111 at each of the four corners of the top cover 11, and one outer peripheral positioning groove 111 at the center of each of the four sides of the top cover 11. In addition, the top cover 11 has a central positioning groove 111 in its center. The eight outer peripheral positioning grooves 111 and the central groove correspond one-to-one with the bottom feet 121 of the upper enclosure box 1, used to place the bottom feet 121 of the upper enclosure box 12. In addition, the top cover 11 may only have outer peripheral positioning grooves 111. At least three outer peripheral positioning grooves 111 are respectively set on different sides of the top cover 11 to ensure the stacking stability of the upper enclosure box 1. This application does not limit the specific number and setting position of the positioning grooves 111.

[0051] A support surface 112 is formed between the top of the side wall of the positioning groove 111 near the outer side of the top cover 11 and the outer edge of the top cover 11, with the support surface 112 facing upwards. The bottom of the top cover 11 is vertically aligned with the support surface 112 and rests against the top of the enclosure 13. The bottom feet 121 of the upper enclosure box 1 are partially placed on the support surface 112, so that the weight of the upper enclosure box 1 can be transferred vertically downwards to the enclosure 13 through the support surface 112.

[0052] Furthermore, the top outer edge of the top cover 11 is provided with multiple support portions 113, which protrude from the bottom of the positioning groove 111. The bottom surface of the support portion 113 abuts against the top of the enclosure 13. One support portion 113 extends continuously along the outer side of a positioning groove 111, and the top surface of the support portion 113 forms a support surface 112. The inner sidewall of the support portion 113 faces the positioning groove 111, that is, the sidewall of the positioning groove 111 near the outer edge of the top cover 11. The continuous extension of the support portion 113 along the outer side of the positioning groove 111 makes the support surface 112 extend continuously along the outer side of the positioning groove 111, thereby increasing the contact area between the support surface 112 of the support portion 113 and the bottom foot 121 of the upper enclosure box 1, and improving the structural strength of the top cover 11. In this embodiment, each positioning groove 111 has a support portion 113 on its outer side. The support portions 113 at the positioning grooves 111 at the four corners of the top cover 11 are L-shaped and extend to fit the two adjacent outer sides of the positioning grooves 111. The support portions 113 at the positioning grooves 111 in the middle of the side of the top cover 11 are straight and extend in a straight line.

[0053] Furthermore, the support surface 112 is lower than the top surface of the top cover 11. The top cover 11 is thinner at the position corresponding to the support surface 112, which can reduce the material of the surrounding plate 13, reduce production costs, and at the same time, it does not affect the fit between the other original structures of the top cover 11 and the surrounding plate 13, thus reducing structural interference. In some other embodiments, the support surface 112 may be flush with the top surface of the top cover 11.

[0054] Specifically, the top cover 11 has a downward-facing lower mounting groove 114 along its outer periphery. The lower mounting groove 114 is used to mate with the top of the enclosure 13, so that the top periphery of the enclosure 13 can be embedded in the lower mounting groove 114, and the support surface 112 is located above the lower mounting groove 114. That is, the bottom surface of the lower mounting groove 114 is the bottom surface of the support part 113, which is used to abut against the top of the enclosure 13, thereby transferring the weight of the upper enclosure box 1 downward in the vertical direction.

[0055] Furthermore, the top surface of the top cover 11 is provided with multiple strap grooves 115 arranged in a crisscross pattern, with the strap grooves 115 and positioning grooves 111 spaced apart. The straps can be used to bind the enclosure box 1 vertically, and the strap grooves 115 are used to hold the straps in place, preventing the straps from shifting and improving the stability of the overall structure of the enclosure box 1.

[0056] Furthermore, the top cover 11 has a first periphery 116 on its outer periphery. The first periphery 116 extends downward and surrounds the outer periphery of the top opening of the surrounding plate 13 when the top cover 11 is placed on the surrounding plate 13. Specifically, the first periphery 116 extends along the outer wall of the lower mounting groove 114. After the lower mounting groove 114 is engaged with the top periphery of the surrounding plate 13, the first periphery 116 is located on the outer periphery of the surrounding plate 13.

[0057] In this application, the top cover 11 and the surrounding panel 13 are detachably connected.

[0058] The top cover 11 is provided with a plurality of first latches 118, which are spaced apart along the outer periphery of the top cover 11. The surrounding plate 13 is provided with first lock holes corresponding to the first latches 118 one by one. The first latches 118 can extend outward relative to the top cover 11 and enter the first lock hole, or they can retract inward relative to the top cover 11 and exit the first lock hole.

[0059] Specifically, four first latches 118 are respectively located on the four sides of the top cover 11. Correspondingly, each of the four side plates of the surrounding plate 13 is provided with a first locking hole for the first latches 118 to pass through, thereby improving the connection stability between the top cover 11 and the surrounding plate 13. By extending all the first latches 118 on the top cover 11 outward into the first locking holes, the top cover 11 and the surrounding plate 13 are locked together. By retracting all the first latches 118 on the top cover 11 inward and withdrawing them from the first locking holes, the top cover 11 can be removed from the surrounding plate 13.

[0060] Furthermore, the top surface of the top cover 11 is provided with a second receiving groove 119, which is spaced apart from the positioning groove 111, and the first latch 118 is slidably disposed in the second receiving groove 119.

[0061] The first latch 118 can be housed in the second receiving groove 119 to ensure that the top surface of the top cover 11 is flat. In addition, the first latch 118 can be slidably disposed at the bottom of the second receiving groove 119 in the horizontal direction, restricting the first latch 118 from extending outward relative to the second receiving groove 119 or retracting inward into the second receiving groove 119.

[0062] In addition, the first latch 118 can be limited between the inner and outer walls of the second receiving groove 119.

[0063] The inner sidewall of the second receiving groove 119 forms a through hole opposite the position of the first lock hole. This allows the end of the first latch 118 opposite the first lock hole to pass through the through hole, exit the second receiving groove 119, and enter the first lock hole.

[0064] Figure 4 A schematic diagram of the base 12 is shown.

[0065] Reference Figure 1 and Figure 4 The base 12 is a rectangular tray structure, and the bottom of the surrounding plate 13 can be placed on the base 12 so that the base 12 can seal the bottom opening of the surrounding plate 13. The bottom surface of the base 12 is provided with multiple feet 121. The base 12 of this application has nine feet 121, including outer peripheral feet 121 and central feet 121. Eight outer peripheral feet 121 are spaced apart along the outer periphery of the base 12, four outer peripheral feet 121 are located at the four corners of the bottom of the base 12, and one outer peripheral foot 121 is provided in the middle of each of the four sides of the base 12. The positions of the outer peripheral feet 121 and the outer peripheral positioning grooves 111 correspond vertically. One central foot 121 is located in the middle of the bottom surface of the base 12 and corresponds vertically to the central positioning groove 111. The bottom feet 121 of the bottom support 12 of the upper-layer cofferdam 1 are inserted one-to-one into the positioning groove 111 of the lower-layer cofferdam 1, thereby realizing the stacking positioning of the cofferdam 1.

[0066] In this application, the bottom of the foot 121 is recessed along the vertical direction corresponding to the support surface 112 to form a stepped surface 122. That is, the stepped surface 122 formed by a portion of the bottom of the outer peripheral foot 121 is higher than the bottom surface of the foot 121. This allows the outer peripheral foot 121 of the upper enclosure box 1 to be placed simultaneously on the bottom surface of the positioning groove 111 of the lower enclosure box 1 and on the support surface 112, thereby enabling the weight of the upper enclosure box 1 to be vertically transferred to the enclosure 13 of the lower enclosure box 1 through the support surface 112.

[0067] Specifically, a stepped groove 123 is provided on the bottom outer edge of the base 121, and a downward-facing stepped surface 122 is formed on the stepped groove 123, extending to fit the outer edge of the base 121. The stepped groove 123 on the bottom outer edge of the base 121 located on the outer periphery of the base 12 creates a concave notch on the bottom outer edge of the base 121. The stepped surface 122 is formed on the downward-facing plane of the stepped groove 123, and the stepped surface 122 is adjacent to the outer side wall of the base 121, so that the stepped surface 122 fits the outer edge of the base 121. The extension direction of the step surface 122 of the base 121 corresponds one-to-one with the extension direction of the support surface 112 of the support part 113. The step surface 122 at the four corners of the base 121 extends in an L-shape to fit the outer wall of the base 121. The step surface 122 at the middle of the side of the base 12 extends in a straight line to fit the outer wall of the base 121.

[0068] Furthermore, the horizontal dimension of the base 121 gradually tapers downwards. The cross-sectional area of ​​the base 121 gradually decreases from top to bottom, allowing the sidewalls of the base 121 to form an inwardly inclined guide surface structure, facilitating the alignment and insertion of the base 121 of the upper enclosure box 1 into the positioning groove 111 of the top cover 11 of the lower enclosure box 1. In some specific embodiments, the slope of the sidewalls of the base 121 can be designed to be 3° to 10°.

[0069] Furthermore, at least one sidewall of the base 121 has a corrugated structure, with the concave and convex portions of the corrugated structure extending vertically. Specifically, one sidewall of the base 121 is provided with alternating ridges and grooves, both extending vertically to form a corrugated structure, which can improve the support strength of the base 121. In this embodiment, the corrugated structure is formed on one outer sidewall of the base 121 located at the four corners of the base 12.

[0070] The base 12 has an upward-facing upper mounting groove along its circumferential direction, and the bottom periphery of the enclosure 13 is embedded in the upper mounting groove so that the base 12 can be sealed at the bottom opening of the loading space 131 of the enclosure 13.

[0071] Furthermore, the base 12 has a second periphery 124 on its outer periphery, which extends upward and surrounds the outer periphery of the bottom opening of the panel 13. The inner periphery of the second periphery 124 has a boss 125.

[0072] Furthermore, the base 12 is detachably connected to the side panel 13. The base 12 and the side panel 13, as well as the side panel 13 and the top cover 11, can be detachably connected for easy transportation.

[0073] After the cover 13 is removed from the top cover 11 and the bottom support 12, the top cover 11 can be placed on the bottom support 12, so that the first edge 116 of the top cover 11 can be placed on the boss 125, and the second edge 124 surrounds the outer periphery of the first edge 116. The cover 13 can be folded and stored between the top cover 11 and the bottom support 12.

[0074] Furthermore, the base 12 is provided with a plurality of second latches 126, which are spaced apart along the outer periphery of the base 12. The surrounding plate 13 is provided with second locking holes corresponding to the second latches 126 one by one. The second latches 126 can extend outward relative to the base 12 and enter the second locking hole, or they can retract inward relative to the base 12 and exit the second locking hole.

[0075] Specifically, four second latches 126 are respectively located on the four sides of the base 12. Correspondingly, each of the four side plates of the enclosure 13 has a second locking hole for the second latches 126 to pass through, thereby improving the connection stability between the base 12 and the enclosure 13. By extending the second latches 126 on the base 12 outward into the second locking holes, the base 12 and the enclosure 13 are locked together. By retracting the second latches 126 on the base 12 inward and withdrawing them from the second locking holes, the base 12 can be removed from the enclosure 13.

[0076] Furthermore, the top surface of the base 12 is provided with a third receiving groove 127, which is spaced apart from the base foot 121. The second latch 126 is slidably disposed at the bottom of the third receiving groove 127. The second latch 126 can be housed within the third receiving groove 127. Moreover, the second latch 126 can slide horizontally at the bottom of the third receiving groove 127, restricting the second latch 126 from extending outward relative to the third receiving groove 127 or retracting inward into the third receiving groove 127.

[0077] In addition, the second latch 126 can be limited between the inner and outer walls of the third receiving groove 127.

[0078] The inner wall of the third receiving groove 127 forms a through hole opposite the position of the second lock hole. This allows the end of the second latch 126 opposite the second lock hole to pass through the through hole, exit the third receiving groove 127, and enter the second lock hole.

[0079] Reference Figure 1 The enclosure 13 includes four side panels that form a rectangular loading space 131, which extends vertically. A bottom support 12 rests on the bottom of the enclosure 13 and seals the bottom opening of the loading space 131. A top cover 11 covers the top of the enclosure 13 and seals the top opening of the loading space 131. The bottom support 12, enclosure 13, and top cover 11 can form a closed space.

[0080] The side wall of the enclosure 13 is provided with a retrieval window, and the bottom edge of the retrieval window is provided with a cover plate 132. The cover plate 132 can be closed to the retrieval window, or can be flipped relative to the enclosure 13 to open the retrieval window, so that staff can directly retrieve items from the loading space 131 or put items into the loading space 131 through the retrieval window.

[0081] The side wall of the enclosure 13 is provided with Velcro 133, which is used to adhere to the cover 132 after the retrieval window is opened by flipping it open. Specifically, the cover 132 has adhesive corresponding to the position of the Velcro 133. The adhesive can be attached or removed in conjunction with the Velcro 133, making it convenient for staff to fix the cover 132 after opening the retrieval window. In addition, after the enclosure 13 is closed and the retrieval window is opened, it can also be fixed to the enclosure 13 using a connection method similar to Velcro 133.

[0082] The enclosure box 1 also includes multiple tensioning devices 14. At least two tensioning devices 14 are located on opposite sides of the enclosure 13, and the tensioning devices 14 are connected between the base support 12 and the top cover 11. After installation between the base support 12 and the enclosure 13, and between the enclosure 13 and the top cover 11, the tensioning devices 14 can be used to tighten the base support 12 and the top cover 11, making it easier for workers to close the enclosure box 1, further preventing the base support 12, the enclosure 13, and the top cover 11 from falling off, and improving the structural stability of the enclosure box 1.

[0083] In this embodiment, four tensioning devices 14 are provided, and the four tensioning devices 14 are located on the four sides of the enclosure 13, which further improves the structural stability of the enclosure box 1.

[0084] Furthermore, each tensioning device 14 includes a winding structure, a tensioning band 141, a locking connector 142, and a locking head 143. The winding structure is located inside the base 121. One end of the tensioning band 141 is wound inside the winding structure, and the other end of the tensioning band 141 extends outward from the base 121 and connects to the locking connector 142. The locking head 143 is located on the top cover 11, and the locking connector 142 is used to engage with the locking head 143 one-to-one.

[0085] Specifically, some of the base feet 121 have installation space for installing a winding structure. The tension band 141 can automatically wind up inside the winding structure, or the operator can pull the tension band 141 out relative to the winding structure. The locking head 143 is located on the top cover 11. The locking head 142 and the locking head 143 are detachable snap-fit ​​structures. After the locking head 143 is inserted into the locking head 142, the tension band 141 can automatically tighten through the winding structure, thereby tightening the base feet 121 and the top cover 11. After the locking head 142 is removed from the locking head 143, the tension band 141 can automatically retract into the corresponding winding structure, leaving the locking head 142 exposed outside the base feet 121 for easy grabbing by the operator. The operation is simple and convenient.

[0086] Furthermore, the top surface of the top cover 11 is provided with a plurality of first receiving grooves 117, which extend outward to the outer side wall of the top cover 11. The first receiving grooves 117 and the positioning grooves 111 are spaced apart, and the lock head 143 is disposed in the first receiving groove 117. The top surface of the top cover 11 has reserved the installation position of the lock head 143 through the first receiving grooves 117, and it is convenient for the snap connector 142 on the tension strap 141 to be inserted into the lock head 143 through the first receiving grooves 117, so that the lock head 143 is stored in the first receiving grooves 117 and does not protrude from the top surface of the top cover 11, preventing it from affecting the stacking of the cofferdam box 1 and improving environmental adaptability.

[0087] Because the first receiving groove 117 is spaced apart from the positioning groove 111, and the bottom foot 121 for winding the tension band 141 is aligned vertically with the positioning groove 111, after the tension band 141 is wrapped around the top cover 11, the tension band 141 extends obliquely from the winding structure toward the locking head 143. The first receiving groove 117, the second receiving groove 119, and the positioning groove 111 of this application are spaced apart to avoid interference.

[0088] This application brings the following beneficial effects:

[0089] 1. Strong structural stability. By adjusting the structure of the top cover 11 and the bottom support 12, the collapsible box 1 ensures that the weight of the upper collapsible box 1 can be vertically transferred to the collapsible plate 13 of the lower collapsible box 1 during dynamic load stacking and transportation, thereby reducing the deformation and cracking of the top cover 11 and collapsible plate 13 of the lower collapsible box 1 and ensuring the safety of the goods.

[0090] 2. High environmental adaptability. This collapsible box 1 has reserved installation positions for the first latch 118, the second latch 126, and the tensioning device 14, which allows workers to have a more convenient packing method without affecting the stacking of the boxes, and the operation is simple.

[0091] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this application are indicated by the appended claims.
