Description

Technical Field

[0001] This invention belongs to the field of logistics box technology, and in particular relates to a recyclable and reusable express logistics box. Background Technology

[0002] Logistics boxes are widely used in industries such as machinery, automobiles, home appliances, light industry, and electronics. They are acid and alkali resistant, oil resistant, non-toxic, and odorless, suitable for storing food, easy to clean, facilitate convenient parts turnover, and allow for neat stacking and management. Their rational design and excellent quality make them suitable for transportation, distribution, storage, and processing in factory logistics.

[0003] Since the capacity of existing express delivery boxes is basically fixed, they can only store packages of a certain size. Therefore, it is difficult to adjust the depth and space of the box according to the size and dimensions of the packages, so that the express delivery boxes can be reused to accommodate the stacking and storage of packages of different sizes. Even if the depth of existing boxes can be adjusted, most of them are adjusted by stretching a large box inside a smaller box. Therefore, when storing taller packages, it is difficult to make the side walls of the package fit against the side walls of the upper and lower boxes at the same time, which easily leads to wasted space and affects the storage space. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0005] This invention relates to a recyclable and reusable express delivery box, comprising a box body with a lid, an open bottom, and a bottom plate connected to the bottom of the box body via an elastic corrugated frame. At least three sets of support fastening strips are rotatably mounted on the front and rear side walls of the bottom plate via a detachable assembly, and each support fastening strip has multiple square fastening holes at equal intervals. At least three sets of fastening limiting assemblies arranged in pairs are provided on both the front and rear sides of the box body. These fastening limiting assemblies are used to fasten and fix the support fastening strips to the sides of the box body. At least two sets of partitions are detachably installed inside the box body.

[0006] Furthermore, the disassembly assembly includes a mounting block, mounting screws, and a flexible bending rod. At least three mounting slots are equidistantly provided on the front and rear sides of the box bottom plate, and a mounting block is fixedly installed in each mounting slot by mounting screws. The outer side of each mounting block is connected to the bottom of the support buckle strip by a flexible bending rod.

[0007] Furthermore, the fastening and limiting assembly includes a support block, a sliding block, a connecting block, a locking block, a rotating sleeve, a rotating rod, and a U-shaped limiting block. At least two square sliding holes are equidistantly spaced on the front and rear side walls of the housing. The support block is slidably inserted into the square sliding hole, and a sliding block is installed on the outer end face of the support block. A connecting block is installed on the outer end face of the sliding block, and a locking block is installed on the outer end face of the connecting block. Rotating sleeves are fixed to the wall surfaces where the sliding block, support block, connecting block, and locking block are in contact with each other, and a rotating rod is rotatably connected between every two in contact with each other. A U-shaped limiting block is fixed to the inner end of the support block at the housing, and the U-shaped opening of the U-shaped limiting block is flush with the upper surface of the support block. Limiting grooves are provided on the front and rear inner sides of the housing at positions aligned with the square sliding holes, and the limiting grooves are aligned with the U-shaped limiting blocks. The support block, sliding block, connecting block, and locking block have the same length, and the depth of the square sliding hole and the square fastening hole is the same as the length of the support block.

[0008] Furthermore, the partition is fixed with elastic sealing strips on its four outer walls, and sliding grooves are provided symmetrically on the front and rear side walls of the partition. U-shaped blocks with downward openings are slidably inserted into the sliding grooves. The width of the U-shaped opening of the U-shaped block is equal to the width of the support block, and the depth of the U-shaped opening is greater than the thickness of the support block. The two side walls of the U-shaped opening of the U-shaped block are bent outward to form bent edges, and the distance between the two bent edges is greater than the width of the sliding groove.

[0009] Furthermore, a hidden groove is provided in the front and rear horizontal direction on the upper surface of the partition, and a pull bar is slidably inserted in the hidden groove. The two ends of the pull bar are connected to the upper surface sidewall of the U-shaped block.

[0010] Furthermore, the upper surface of the sliding block is vertically provided with a push hole, and a trapezoidal block is slidably inserted into the push hole. The lower surface of the trapezoidal block is integrally formed with a square block. The lower surface of the square block is connected to the bottom of the push hole by a spring. The top wall of the limiting groove and the square sliding hole, as well as the outer wall of the square sliding hole, are all provided with arc-shaped transition surfaces.

[0011] Furthermore, a limiting strip is fixed at the lower surface of the elastic sealing strip where it aligns with the two side walls of the U-shaped block, and the front and rear widths of the limiting strip and the U-shaped block are equal to the distance between the inner side wall of the U-shaped limiting block and the inner side wall of the box.

[0012] Furthermore, C-shaped handles are fixed to the left and right side walls of the box body and the bottom plate of the box. Hidden sliding holes are opened on the left and right side walls of the bottom plate of the box, and springs are installed in the hidden sliding holes. The other end face of the spring is connected to the end face of the crossbar of the C-shaped handle installed on the left and right side walls of the bottom plate of the box.

[0013] The present invention has the following beneficial effects:

[0014] 1. This invention connects an elastic corrugated frame between the bottom of the box and the bottom plate. Operators can pull or press the box or bottom plate to compress or extend the elastic corrugated frame, thus adjusting the depth and capacity of the entire logistics box. Multiple support and locking strips and locking limit components work together to limit and fix the stretched or compressed elastic corrugated frame, preventing shrinkage and deformation of the extended logistics box during package handling. When it is necessary to divide the extended or original box into multiple layers, partitions can be placed inside the box and supported by the locking limit components. This eliminates the need for supporting components on the inner wall of the box. Furthermore, without partitions inside the box, the lack of supporting components on the inner wall improves the utilization of the internal space and does not interfere with the packages stored inside, thereby increasing the reusability of the logistics box.

[0015] 2. This invention utilizes the cooperation of independently rotating support blocks, sliding blocks, connecting blocks, and locking blocks. The support blocks can slide into the box to support the partitions, while the locking blocks rotate vertically to lock and limit the vertically fastened support strips. When the partitions are no longer needed, the support blocks can retract into the square sliding holes, and the connecting blocks rotate vertically to lock and limit the vertically fastened support strips. Furthermore, the support blocks do not interfere with or obstruct the express items stored inside the box, thereby improving the reusability of the logistics box.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0028] Please see Figures 1-7As shown, the present invention is a recyclable and reusable express logistics box, including a box body 1, a box cover 2 on the box body 1, an open bottom of the box body 1, and a bottom plate 4 connected to the bottom of the box body 1 by an elastic corrugated frame 3. At least three sets of support fastening strips 6 are rotatably installed on the front and rear side walls of the bottom plate 4 through a disassembly assembly 5, and each support fastening strip 6 has multiple square fastening holes 61 equidistantly opened. At least three sets of fastening limiting assemblies 7 are provided on the front and rear sides of the box body 1, arranged in pairs. The fastening limiting assemblies 7 are used to fasten and fix the support fastening strips 6 to the side of the box body 1. At least two sets of partitions 8 are detachably installed inside the box body 1.

[0029] In the design of this invention, a bottom plate 4 is installed at the bottom of the lower opening of the box body 1, and the bottom plate 4 is connected to the bottom of the box body 1 by an elastic corrugated frame 3. When it is necessary to adjust the depth of the logistics box, the supporting fastening strips 6 are sequentially pried off from the fastening limiting assembly 7 to disengage them. Then, the bottom plate 4 is fixed, and the box body 1 is pulled upward, so that the elastic corrugated frame 3 can extend and open upward, increasing the distance between the bottom plate 4 and the upper opening of the box body 1, thereby increasing the depth capacity of the logistics box. Then, multiple supporting fastening strips 6 on the front and rear sides of the bottom plate 4 are fastened and fixed through square fastening holes 61. The snap-fit ​​limiting component 7 secures the extended elastic corrugated frame 3, preventing the extended logistics box from shrinking and deforming during the storage and handling of express packages. When it is necessary to divide the extended or original box 1 into multiple layers, the partition 8 can be placed inside the box 1 and supported by the snap-fit ​​limiting component 7. This eliminates the need for supporting components to be installed on the inner wall of the box 1. Furthermore, without the partition 8 inside the box 1, the inner wall of the box 1 is free of supporting components, thereby improving the utilization rate of the internal space of the box 1 and preventing interference with the express packages stored inside the box 1.

[0030] In one embodiment of the present invention, the disassembly assembly 5 includes a mounting block 51, mounting screws 52, and elastic bending rods 53. At least three mounting slots 41 are equidistantly provided on the front and rear sides of the bottom plate 4, and a mounting block 51 is fixedly mounted in each mounting slot 41 by mounting screws 52. The outer side of each mounting block 51 is connected to the bottom of the support fastening strip 6 by elastic bending rods 53. In the design of the present invention, the support fastening strip 6 is connected to the mounting block 51 by the elastic bending rods 53, facilitating the disassembly and engagement of the support fastening strip 6 from the fastening limiting assembly 7. Furthermore, the cooperation of the mounting block 51 and the mounting screws 52 facilitates the removal and replacement of worn support fastening strips 6 from the bottom plate 4.

[0031] In one embodiment of the present invention, the fastening limiting component 7 includes a support block 71, a sliding block 72, a connecting block 73, a locking block 74, a rotating sleeve 75, a rotating rod 76, and a U-shaped limiting block 77. At least two square sliding holes 11 are equidistantly spaced on the front and rear side walls of the housing 1. The support block 71 is slidably inserted into the square sliding hole 11, and the sliding block 72 is mounted on the outer end face of the support block 71. The connecting block 73 is mounted on the outer end face of the sliding block 72, and the locking block 74 is mounted on the outer end face of the connecting block 73. The sliding block 72, support block 71, connecting block 73, and locking block 74 are mutually fitted together on the wall surfaces. Each of the four components is fixed with a rotating sleeve 75, and a rotating rod 76 is rotatably connected between every two mutually fitting rotating sleeves 75. The support block 71 is fixed with a U-shaped limiting block 77 at the inner end of the housing 1, and the U-shaped opening of the U-shaped limiting block 77 is flush with the upper surface of the support block 71. The front and rear inner sides of the housing 1 are provided with limiting grooves 12 at the position aligned with the square sliding hole 11, and the limiting grooves 12 are aligned with the U-shaped limiting block 77. The support block 71, sliding block 72, connecting block 73 and locking block 74 are of the same length. The depth of the square sliding hole 11 and the square fastening hole 61 is the same as the length of the support block 71.

[0032] In the design of this invention, when it is necessary to fix the extended elastic corrugated frame 3, the supporting fastening strip 6 is first moved to an inclined state and brought close to the side of the housing 1. Then, the locking block 74 is pushed so that half of the connecting block 73 is located in the square sliding hole 11, allowing the locking block 74 to protrude from the outer side of the housing 1. Then, the supporting fastening strip 6 is moved to a vertical state, and the square fastening hole 61 is fastened to the locking block 74. Then, the locking block 74 is pulled outward to fix the supporting block 71. The sliding block 71 is pulled into the square sliding hole 11, and the U-shaped limiting block 77 can enter the limiting stop groove 12 to limit and block the sliding support block 71, making the outer end face of the support block 71 flush with the inner wall of the box 1. The sliding block 72 will enter the square fastening hole 61, and then the connecting block 73 and the locking block 74 will extend out of the outer side of the support fastening strip 6. Then, the connecting block 73 is rotated. At this time, the connecting block 73 will rotate on the side of the sliding block 72 through the cooperation of the rotating sleeve 75 and the rotating rod 76, so that... The connecting block 73 rotates to a vertical position to limit and fix the support fastening strip 6, preventing it from detaching from the sliding block 72. This would affect the support and fixation of the multiple support fastening strips 6 on the extended box 1 and the box bottom plate 4, thereby increasing the internal depth capacity of the box 1. The two rotating sleeves 75 and rotating rods 76 on each connecting block 73 and sliding block 72 are independently installed. When it is necessary to reduce or further increase the distance between the box 1 and the box bottom plate 4, the connecting block 73 is rotated... The movement is in a horizontal state, so that it is at the same level as the sliding block 72 and the support block 71. Then, the locking block 74 is pushed so that half of the locking block 74 enters the square fastening hole 61. Then, the support fastening strip 6 is pushed outward so that it is disengaged from the locking block 74. Then, the box body 1 is pressed so that the elastic corrugated frame 3 contracts. The other square fastening holes 61 on the support fastening strip 6 will align with the locking block 74. Then, the support fastening strip 6 is fixed again, which makes it easier to continue to adjust the overall height of the box body 1.

[0033] When the partition 8 needs to be placed into the box 1, the locking block 74 needs to be pushed first, so that the support block 71 slides into the box 1. At this time, the sliding block 72 will be located in the square sliding hole 11, and the support block 71 will extend into the box 1. Then, the two sets of three support blocks 71 on the front and rear sides will suspend and support the partition 8. Therefore, it is not necessary to install a component to fix and support the partition 8 inside the box 1. Then, the support buckle 6 is moved to a vertical position, so that the square buckle hole 61 is engaged with the connecting block 73. Then, the locking block 74 is rotated so that it is vertically attached to the outer side of the support buckle 6. Thus, the buckle limiting component 7 can not only limit and fix the vertical support buckle 6, but also support and limit the partition 8 placed in the box 1. This not only expands the depth capacity of the box 1, but also allows the box 1 to be divided for storing express items.

[0034] In one embodiment of the present invention, an elastic sealing strip 81 is fixed to the outer walls of the partition 8, and sliding grooves 82 are provided at symmetrical positions on the front and rear side walls of the partition 8. A U-shaped block 85 with its opening facing downward is slidably inserted into the sliding groove 82. The width of the U-shaped opening of the U-shaped block 85 is equal to the width of the support block 71, and the depth of the U-shaped opening is greater than the thickness of the support block 71. The two side walls of the U-shaped opening of the U-shaped block 85 are bent outward to form bent edges 851, and the distance between the two bent edges 851 is greater than the width of the sliding groove 82.

[0035] In the design of this invention, when the partition 8 is supported on the extended support block 71, the elastic sealing strip 81 can elastically compress and seal the partition 8 and the inner wall of the box 1, allowing it to store different types of express delivery items. For example, items that need to be frozen can be placed at the bottom, and then ice packs and other items can be placed in the space below. At the same time, when the partition 8 is placed on the support block 71 for support, the U-shaped opening of the U-shaped block 85 facing the direction of the opening will be engaged with the support block 71, which not only achieves the limiting and fixing of the partition 8, but also... The block 85 can block and limit the U-shaped limiting block 77, thus facilitating the insertion of the support block 71 into the box 1 and limiting and fixing the partition 8. This prevents the support block 71 from sliding off the lower surface of the partition 8 and entering the square sliding hole 11 when the locking block 74 rotates to limit and fix the support fastening strip 6, thereby affecting the stable installation support of the support block 71 for the partition 8. The design of the bent edge 851 can prevent the U-shaped block 85 from detaching upward from the sliding groove hole 82, thus affecting the stable and safe support of the partition 8 on the support block 71.

[0036] In one embodiment of the present invention, a hidden groove 83 is provided in the horizontal direction of the upper surface of the partition 8, and a pull strip 86 is slidably inserted into the hidden groove 83. The two ends of the pull strip 86 are connected to the upper surface sidewall of the U-shaped block 85. In the design of the present invention, when the partition 8 needs to be disassembled, the pull strip 86 can be disengaged upward from the hidden groove 83. At the same time, the pull strip 86 will drive the U-shaped block 85 to slide upward in the sliding groove 82, so that the U-shaped opening of the U-shaped block 85 can be disengaged from the support block 71 and the partition 8, which is sealed by compression, can be quickly disassembled from the box 1. When the partition 8 is supported on the support block 71, the pull strip 86 is pressed down to make it snap into the hidden groove 83. At the same time, the U-shaped block 85 will snap into the support block 71, so that the upper surface of the partition 8 is in a flat state for storing express items.

[0037] In one embodiment of the present invention, a push hole 721 is vertically opened on the upper surface of the sliding block 72, and a trapezoidal block 9 is slidably inserted into the push hole 721. A square block 91 is integrally formed on the lower surface of the trapezoidal block 9. The lower surface of the square block 91 is connected to the bottom of the push hole 721 by a spring. An arc-shaped transition surface is provided at the top wall of the limiting groove 12 and the square sliding hole 11, as well as at the outer wall of the square sliding hole 11.

[0038] In the design of this invention, when it is necessary to remove the partition 8 from the housing 1, the locking block 74 can be rotated to a horizontal position first. Then, the support buckle 6 can be disassembled from the connecting block 73 and the locking block 74. Then, the locking block 74 can be pushed so that the connecting block 73 enters the square sliding hole 11. At this time, the connecting block 73 will enter the U-shaped opening of the U-shaped block 85. Then, the elastic restoring force of the spring compressed in the push hole 721 will push the trapezoidal block 9 upward through the square block 91. The square block 91 will not protrude out of the push hole 721. Then, the U-shaped block 85 will be pushed upward and protrude out of the sliding groove hole 82. Then, the U-shaped block 85 will drive the pull bar 86 to disengage upward from the hidden groove 83. This facilitates the disassembly personnel to quickly pull the pull bar 86 to disassemble the partition 8, preventing the pull bar 86 from being hidden in the hidden groove 83 and thus affecting the disassembly efficiency of the partition 8. When the sliding block 72 slides into the square sliding hole 11, the arc transition surface will cooperate with the inclined surface of the trapezoidal block 9, compressing the trapezoidal block 9 into the push hole 721, at which time the spring will be in a compressed state. When the support block 71 is not needed to support the partition 8 and it slides into the square sliding hole 11, the sliding block 72 will be located in the square fastening hole 61, and the trapezoidal block 9 will be compressed into the square fastening hole 61, so that it does not interfere with the normal limiting and fixing of the fastening limit component 7 on the support fastening bar 6.

[0039] In one embodiment of the present invention, a limiting strip 84 is fixed at the lower surface of the elastic sealing strip 81 where it aligns with the two side walls of the U-shaped block 85, and the front and rear widths of the limiting strip 84 and the U-shaped block 85 are equal to the distance between the inner side wall of the U-shaped limiting block 77 and the inner side wall of the box 1. In the design of the present invention, the mutual cooperation between the limiting strip 84 below the elastic sealing strip 81 and the U-shaped block 85 can further limit the U-shaped limiting block 77, and further prevent the support block 71 from detaching from the support and fixation of the partition 8.

[0040] In one embodiment of the present invention, C-shaped handles 10 are fixed to the left and right side walls of the box body 1 and the bottom plate 4. The left and right side walls of the bottom plate 4 are provided with hidden sliding holes 42, and springs are installed in the hidden sliding holes 42. The other end face of the spring is connected to the end face of the crossbar of the C-shaped handles 10 installed on the left and right side walls of the bottom plate 4. In the design of the present invention, the C-shaped handles 10 on the box body 1 can facilitate the handling of the logistics box containing express items. At the same time, the C-shaped handles 10 on the bottom plate 4 can be pulled out to assist in raising the box. When the elastic corrugated frame 3 is extended, the lower C-shaped handles 10 can be pulled out, and then the lower C-shaped handles 10 can be stepped on or pressed down to lift the upper C-shaped handles 10, so that the logistics box can be quickly extended.

[0041] Working principle:

[0042] When the depth of the logistics box needs to be adjusted, the support buckle 6 is pulled off the buckle limit component 7 in sequence to disengage it from the fixation. Then, the lower C-shaped handle 10 is pulled out, and the lower C-shaped handle 10 is stepped on or pressed down. The upper C-shaped handle 10 is then lifted to quickly extend the logistics box.

[0043] When it is necessary to fix the extended elastic corrugated frame 3, first move the support buckle 6 to an inclined state and bring it close to the side of the box 1. Then push the locking block 74 so that half of the connecting block 73 is in the square sliding hole 11, allowing the locking block 74 to protrude from the outer side of the box 1. Then continue to move the support buckle 6 to a vertical state, and let the square buckle hole 61 engage with the locking block 74. Then pull the locking block 74 outward to pull the support block 71 into the square sliding hole 11, and the U-shaped limiting block 77 can enter the limiting position. The groove 12 limits and blocks the sliding support block 71, and makes the outer end face of the support block 71 flush with the inner wall of the box 1. The sliding block 72 will enter the square fastening hole 61. Then the connecting block 73 and the locking block 74 will extend out of the outer side of the support fastening strip 6. Then the connecting block 73 will rotate. At this time, the connecting block 73 will rotate on the side of the sliding block 72 through the cooperation of the rotating sleeve 75 and the rotating rod 76, so that the connecting block 73 will rotate into a vertical state to limit and fix the support fastening strip 6, preventing the support fastening strip 6 from detaching from the sliding block 72.

[0044] When it is necessary to reduce or further increase the distance between the box body 1 and the bottom plate 4, the connecting block 73 is rotated to a horizontal position so that it is at the same level as the sliding block 72 and the support block 71. Then, the locking block 74 is pushed so that half of the locking block 74 enters the square fastening hole 61. Then, the support fastening strip 6 is pushed outward so that it is disengaged from the locking block 74. Then, the C-shaped handle 10 on the outside of the box body 1 is pressed so that the elastic corrugated frame 3 retracts. The other square fastening holes 61 on the support fastening strip 6 will align with the locking block 74. Then, the support fastening strip 6 is fixed again, which makes it easier to continue to adjust the overall height of the box body 1.

[0045] When the partition 8 needs to be placed into the box 1, the locking block 74 needs to be pushed first, so that the support block 71 slides into the box 1. At this time, the sliding block 72 will be located in the square sliding hole 11, and the support block 71 will extend into the box 1. Then, the two sets of three support blocks 71 on the front and rear sides will suspend and support the partition 8, so there is no need to install a component to fix and support the partition 8 inside the box 1. Then, the support buckle 6 is moved to a vertical position, so that the square buckle hole 61 is engaged with the connecting block 73. Then, the locking block 74 is rotated so that it is vertically attached to the outer side of the support buckle 6. Thus, the buckle limiting component 7 can both limit and fix the vertical support buckle 6, and support and limit the partition 8 placed in the box 1, so as to facilitate the layering and storage of express items in the box 1.
