Description

Technical Field

[0001] This utility model belongs to the field of logistics packaging box technology, specifically relating to a logistics packaging box that is easy to stack. Background Technology

[0002] In the logistics and transportation sector, cargo palletizing is a key step in improving space utilization and transportation efficiency.

[0003] Traditional logistics packaging boxes lack effective positioning and limiting structures during the stacking process. When stacking upper and lower layers of packaging boxes, they are prone to shifting and misalignment, and may even collapse during transportation, resulting in damage to the goods. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a logistics packaging box that is easy to stack, solving the problem that traditional logistics packaging boxes lack effective positioning and limiting structures during the stacking process, and are prone to displacement and misalignment when stacked, and may even collapse during transportation, leading to damage to goods.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a logistics packaging box that is easy to palletize, comprising an outer box body, which is fitted over the outer side of an inner box body and anti-collision corners. A mounting plate is fixedly provided on the top surface of the outer box body. Positioning blocks fixed at the four corners of the top surface of the mounting plate are fitted into positioning holes opened at the four corners of the bottom surface of the box cover. A protective shell is fixedly provided on the top surface of the box cover, and a limiting component is provided inside the protective shell. The limiting component includes a worm gear, which meshes with a worm wheel. The worm wheel is connected to a support rod at the four corners of the top surface of the box cover through a transmission component. The top end of the support rod is connected to the bottom surface of a limiting plate through a limiting rod. The limiting plate abuts against the bottom surface of the bottom plate of the adjacent packaging box.

[0006] The beneficial effects of this utility model are:

[0007] By engaging the positioning block on the top surface of the mounting plate with the positioning hole on the bottom surface of the box lid, precise positioning of the upper and lower packaging boxes is achieved, preventing offset during stacking. In conjunction with the limiting component, the drive transmission component causes the limiting plate to rotate, forming a stable locking structure in its limiting cavity, restricting the horizontal movement of the upper packaging box. Even in bumpy transportation environments, it can effectively prevent the packaging box from shaking, shifting, or collapsing, ensuring the stability of the stacking structure.

[0008] The green and red indicator blocks on the adjustment block provide operators with an intuitive display of the working status of the limit plate (5).

[0009] To enable quick fixing and disassembly of adjacent stacked devices:

[0010] As a further improvement to the above technical solution: the transmission assembly includes two sets of driven wheels II, each set of two driven wheels II being rotatably positioned diagonally within the mounting cavity of the box cover. The top surface of one driven wheel II in each set is connected to a driven wheel I via a mounting rod. The two driven wheels I are connected to the driving wheel via a synchronous belt I. The driving wheel is fitted onto the outside of a rotating rod. The bottom end of the rotating rod is rotatably connected to the center of the bottom surface of the mounting cavity. The top end of the rotating rod passes through the box cover and is rotatably connected to the center of the bottom surface of the worm gear. The driven wheels II are connected via a synchronous belt II. The movable rods on the top surfaces of the driven wheels I and II pass through the top surface of the box cover. The movable rods on the top surfaces of the driven wheels I and II are coaxially and fixedly connected to the bottom end of the support rod.

[0011] The beneficial effects of this improvement are: the transmission assembly enables driven wheel one and driven wheel two to drive the four support rods to rotate synchronously, so that the rotation amplitude of the four sets of limit plates is consistent, the rotation angle of the limit plates can be quickly adjusted, and the adjacent stacked devices can be quickly fixed and quickly disassembled.

[0012] To visually determine whether the limiting plate has rotated into place and abutted against the adjacent base plate:

[0013] As a further improvement to the above technical solution: an adjustment block is fixed at one end of the worm gear, and two sets of indicator color blocks are arranged opposite each other on the surface of the adjustment block. The two sets of indicator color blocks are set to green and red respectively. An indicator rod is fixed on one side of the box cover to guide the indicator color blocks, and the end of the indicator rod points to the indicator color block on the adjustment block to indicate the working status of the limit plate.

[0014] The beneficial effect of this improvement is that, by matching the indicator rod with the indicator color block, the operator can intuitively judge whether the limit plate has rotated into place and abutted the adjacent base plate.

[0015] To restrict the movement of adjacent stacking devices:

[0016] As a further improvement to the above technical solution: cylindrical limiting cavities are provided at the four corners inside the base plate, and the bottom surface of the limiting cavity penetrates the base plate to form an elliptical insertion hole. A limiting plate is slidably inserted into the insertion hole, and the limiting plate matches the shape of the insertion hole and is elliptical.

[0017] The beneficial effects of this improvement are as follows: when the limiting plate rotates to be perpendicular to the insertion hole, it forms a locking structure with the limiting cavity, which can firmly restrict the movement of adjacent stacking devices, effectively prevent relative sliding or misalignment of the devices during stacking and transportation, and greatly enhance the stability of the stacking structure.

[0018] To ensure the lid is securely fastened to the outer box:

[0019] As a further improvement to the above technical solution: the anti-collision corner is fixed at the corner inside the outer box, the anti-collision corner fits the edge of the inner box, and the outer edge of the box cover is provided with straps at the four corners, the buckle at the end of the straps is engaged with the limiting buckle at the top edge of the outer box.

[0020] The beneficial effects of this improvement are: the straps and limit buckles lock the lid to the outer box, preventing the lid from falling off or loosening during transportation, and ensuring the airtightness and safety of the contents.

[0021] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0030] like Figure 1-6As shown, a logistics packaging box that is easy to palletize includes an outer box body 1, which is fitted on the outside of an inner box body 102 and anti-collision corners 103. An mounting plate 101 is fixedly provided on the top surface of the outer box body 1. Positioning blocks 1011 fixed at the four corners of the top surface of the mounting plate 101 are fitted into positioning holes 803 opened at the four corners of the bottom surface of the box cover 8. A protective shell 802 is fixedly provided on the top surface of the box cover 8, and a limiting component 3 is provided inside the protective shell 802. The limiting component 3 includes a worm gear 301, which meshes with a worm wheel 302. The worm wheel 302 is connected to a support rod 4 at the four corners of the top surface of the box cover 8 through a transmission component. The top of the support rod 4 is connected to the bottom surface of a limiting plate 5 through a limiting rod. The limiting plate 5 abuts against the bottom surface of the bottom plate 2 of the adjacent packaging box.

[0031] The transmission assembly includes two sets of driven wheels 304. Each set has two driven wheels 304 rotatably positioned diagonally within the mounting cavity of the cover 8. The top surface of one driven wheel 304 in each set is connected to a driven wheel 303 via a mounting rod. The two driven wheels 303 are connected to a driving wheel 305 via a synchronous belt 306. The driving wheel 305 is fitted onto the outside of a rotating rod. The bottom end of the rotating rod is rotatably connected to the center of the bottom surface of the mounting cavity, and the top end of the rotating rod passes through and rotatably connects to the cover 8, and is fixedly connected to the center of the bottom surface of the worm gear 302. The driven wheels... The second 304 is connected by a synchronous belt 307. The movable rod on the top surface of the driven wheel 303 and the driven wheel 304 passes through the top surface of the cover 8. The movable rod on the top surface of the driven wheel 303 and the driven wheel 304 is coaxially fixedly connected to the bottom end of the support rod 4. The transmission assembly enables the driven wheel 303 and the driven wheel 304 to synchronously drive the four support rods 4 to rotate, so that the rotation amplitude of the four sets of limiting plates 5 is consistent, and the rotation angle of the limiting plates 5 can be quickly adjusted, so that the adjacent stacked devices can be quickly fixed and quickly disassembled.

[0032] One end of the worm gear 301 is fixed with an adjustment block, and two sets of indicator color blocks are arranged opposite each other on the surface of the adjustment block. The two sets of indicator color blocks are set to green and red respectively. One side of the box cover 8 is fixed with an indicator rod 801 that guides the indicator color blocks, and the end of the indicator rod 801 points to the indicator color block on the adjustment block to show the working status of the limit plate 5. Through the correspondence between the indicator rod 801 and the indicator color block, the operator can intuitively judge whether the limit plate 5 has rotated into place and abutted the adjacent bottom plate 2.

[0033] Cylindrical limiting cavities 201 are provided at the four corners of the base plate 2. The bottom surface of the limiting cavity 201 penetrates the base plate 2 to form an elliptical insertion hole 202. A limiting plate 5 slides through the insertion hole 202. The limiting plate 5 matches the shape of the insertion hole 202 and is elliptical. When the limiting plate 5 rotates to be perpendicular to the insertion hole 202, it forms a snap-fit ​​structure with the limiting cavity 201, which can firmly restrict the movement of adjacent stacking devices, effectively prevent relative sliding or misalignment of devices during stacking and transportation, and greatly enhance the stability of the stacking structure.

[0034] The anti-collision corner 103 is fixed at the inner corner of the outer box 1. The anti-collision corner 103 fits against the corner of the inner box 102. The outer edge of the box cover 8 is provided with a strap 6 at each of the four corners. The buckle at the end of the strap 6 is engaged with the limiting buckle 7 at the top edge of the outer box 1. The strap 6 and the limiting buckle 7 are engaged to lock the box cover 8 to the outer box 1, preventing the box cover from falling off or loosening during transportation, and ensuring the airtightness and safety of the contents.

[0035] The working principle and usage process of this utility model are as follows: Place the items to be transported into the inner box 102, cover the outer box 1 with the box lid 8, and embed the positioning blocks 1011 at the four corners of the top surface of the mounting plate 101 into the positioning holes 803 at the four corners of the bottom surface of the box lid 8 to achieve precise positioning. Then, engage the buckle 6 on the edge of the box lid 8 with the limiting buckle 7 at the top of the outer box 1 to lock the box lid and prevent it from falling off during transportation. Place the packaged box stably as the lower layer and observe the indicator on one side of the box lid 8. If rod 801 points to the red indicator block on the adjusting block of worm gear 301, it indicates that the limiting plate 5 overlaps with the hole 202 at the bottom end of the base plate 2 of the adjacent device to be stacked. The device to be stacked can then be lifted, and the limiting plate 5 of the device placed below can be slid through the insertion hole 202 into the limiting cavity 201. When the top surface of the limiting plate 5 contacts the inner top surface of the limiting cavity 201, the operator releases the lifted device and rotates the adjusting block of the device below to replace the worm gear. The worm gear 301 rotates, causing the worm wheel 302, which meshes with it, to rotate. The rotation of the worm wheel 302 drives the driving wheel 305 to rotate synchronously via a rotating rod. The driving wheel 305 drives two driven wheels 303 to rotate via a timing belt. Each set of driven wheels 303 drives driven wheels 304 to rotate synchronously via a mounting rod. At this time, the timing belt causes the two driven wheels 304 to rotate synchronously. The synchronous rotation of driven wheels 303 and driven wheels 304 is achieved through a movable... The rod transmits power to the four support rods 4, causing the four support rods 4 to rotate synchronously. The rotation of the support rods 4 drives the rotation of the limiting plate 5, causing the limiting plate 5 to rotate within the limiting cavity 201. Continue rotating the adjusting block until the indicator rod 801 points to the green indicator block. At this time, the limiting plate 5 has rotated 90° from being parallel to the insertion hole 202 to being perpendicular to it, forming a locking with the limiting cavity 201, restricting the movement of the upper packaging box. Repeat the operation to complete multi-layer stacking. Similarly, the stacking device can be disassembled by reversing the operation.
