Combined with the bidirectional compression structure of the connecting protective plate, it adapts to cartons of different heights, preventing the top from deforming due to load.

Description

Technical Field

[0001] This application relates to the field of packaging carton technology, and in particular to a compression-free stacking packaging carton. Background Technology

[0002] As an indispensable part of modern logistics, packaging cartons bear the important responsibility of containing, protecting, and presenting products. The physical performance indicators of packaging cartons serve as the basis for their quality assessment. Depending on the materials used, there are corrugated cartons, single-layer cardboard boxes, etc. Three-layer and five-layer cardboard are commonly used, while seven-layer cardboard is less common. Each layer consists of linerboard, corrugated paper, core paper, and face paper. Linerboard and face paper are made of kraft paper or kraft paper, while corrugated paper is used for the core paper. This provides convenience for loading and unloading, inventory, stacking, shipping, receiving, transshipment, and sales counting.

[0003] A search revealed that CN221294452U discloses a pressure-resistant packaging carton. A support mechanism is installed inside the carton's interior, with a pressure-resistant sheet adhering to the inner wall of the carton. This effectively improves the pressure resistance of the carton's side walls, preventing goods placed around the carton during transport from collapsing due to impacts from shaking. The sponge pad effectively protects the carton, ensuring that even when heavy objects are placed on top, the pressure from the support mechanism does not cause indentations on the inner wall of the carton.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist that need improvement: The device strengthens the rigidity of the side walls by installing a fixing frame inside the carton, but since the mounting frame is only located at both ends, it is not easy to provide auxiliary support for the top of the carton and the other two sides, and there is still a significant risk of collapse; On the other hand, the magnetic blocks of the device are installed on the inside, which has the effect of attracting different shapes, but the packaging box cannot be used to package metal packaging, thus narrowing the applicable scope of the packaging box and making it inconvenient to use. Utility Model Content

[0005] This application provides a non-crushable stackable packaging carton to improve the following technical problems: The above-mentioned device strengthens the rigidity of the side walls by installing a fixing frame inside the carton, but since the fixing frame is only set at both ends, it is not easy to provide auxiliary support for the top and other sides of the carton, and there is still a large risk of collapse; On the other hand, the magnetic blocks of the above-mentioned device are installed on the inside, which has the effect of attracting different shapes, but the above-mentioned packaging box cannot be used to package metal packaging, thereby reducing the applicable scope of the packaging box and making it inconvenient to use.

[0006] This application provides a compression-free stacking packaging carton, employing the following technical solution:

[0007] A compression-free stacking packaging carton includes a carton body, a hollow positioning frame, an F-shaped edge-blocking bracket, a support frame, a top assembly, and a side wall fitting assembly. The hollow positioning frame is slidably connected to the outside of the F-shaped edge-blocking bracket, and the outside of the F-shaped edge-blocking bracket is tightly fitted to the surface of the carton body. The support frame is fixedly connected to the top of the hollow positioning frame. The top assembly is installed on the inside of the support frame, and the side wall fitting assembly is installed on the outside of the carton body.

[0008] The hollow positioning frame is used to support the support frame. The support frame, together with the top component, is closely attached to the inner wall of the feeding end of the carton body. The F-shaped edge support is stretched outward from the hollow positioning frame and attached to the inner wall of the carton body. The side wall attachment component is attracted to one side surface of the F-shaped edge support through magnetic attraction.

[0009] In one feasible technical solution of this application, the top assembly includes a handle, a lifting screw, a thrust bearing, and a top plate. The outer side of the handle is fixedly connected to the bottom of the lifting screw. The lifting screw is threadedly connected to the middle of the support frame and rotatably connected to the bottom of the thrust bearing. The thrust bearing is fixedly connected to the bottom of the top plate. The top surface of the top plate abuts against the folded surface of the carton body.

[0010] In one feasible technical solution of this application, the sidewall bonding assembly includes a bonding vertical plate, an elastic stretch band, and a butt guard plate. The bonding vertical plate is tightly bonded to the outside of the carton body, the elastic stretch band is fixedly connected to the top of the bonding vertical plate, and the butt guard plate is fixedly connected to the outside of the elastic stretch band.

[0011] In one feasible technical solution of this application, the docking protective plate forms a bidirectional extrusion structure with the top plate through the folding surface of the carton body.

[0012] In one feasible technical solution of this application, magnetic blocks that attract each other are provided on the opposite sides of the bonding vertical plate and the F-shaped edge support, and the magnetic blocks located on the opposite sides of the bonding vertical plate and the F-shaped edge support are irregularly shaped magnets.

[0013] In one feasible technical solution of this application, the opposite sides of the F-shaped abutment bracket are connected with turnbuckles by rope wrapping.

[0014] In one feasible technical solution of this application, a transverse support rod is also provided inside the carton body, and the two ends of the transverse support rod are inserted into the inside of the F-shaped edge support bracket.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] This device, through the sliding cooperation of the F-shaped edge support bracket and the hollow positioning frame, can be stretched to the inner walls of the four sides of the carton and fit tightly. Combined with the transverse insertion structure of the horizontal support rod, it forms a three-dimensional support frame, covering the top, sides, and both ends of the carton. This allows the device to disperse the stacking stress and prevent local collapse, making it especially suitable for multi-layer stacking of heavy goods. The height of the top plate can be adjusted by rotating the handle, actively pressing against the top folded surface of the carton. Combined with the bi-directional extrusion structure of the docking protective plate, it adapts to cartons of different heights and prevents the top from deforming due to load. In addition, external magnetic fixation replaces the built-in magnetic blocks, and the elastic tension band connects the fitting vertical plate and the docking protective plate, providing flexible tension on the basis of magnetic attraction to ensure that the support and the carton wall fit firmly.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a crush-free stacking packaging carton. (Refer to...) Figures 1 to 5 The non-crushable stacking packaging carton includes a carton body 1, a hollow positioning frame 2, an F-shaped edge support bracket 3, a support frame 4, a top component 5, and a side wall fitting component 6. The hollow positioning frame 2 is slidably connected to the outside of the F-shaped edge support bracket 3, and the outside of the F-shaped edge support bracket 3 is tightly fitted to the surface of the carton body 1. The support frame 4 is fixedly connected to the top of the hollow positioning frame 2. The top component 5 is installed on the inside of the support frame 4, and the side wall fitting component 6 is installed on the outside of the carton body 1.

[0034] The hollow positioning frame 2 is used to support the support frame 4. The support frame 4, together with the top component 5, is tightly attached to the inner wall of the feeding end of the carton body 1. The F-shaped edge support 3 is stretched outward from the hollow positioning frame 2 and attached to the inner wall of the carton body 1. The side wall attachment component 6 is attracted to one side surface of the F-shaped edge support 3 through magnetic attraction.

[0035] The top assembly 5 includes a handle 51, a lifting screw 52, ​​a thrust bearing 53, and a top plate 54. The outer side of the handle 51 is fixedly connected to the bottom of the lifting screw 52. The lifting screw 52 is threadedly connected to the middle of the support frame 4 and rotatably connected to the bottom of the thrust bearing 53. The thrust bearing 53 is fixedly connected to the bottom of the top plate 54. The top surface of the top plate 54 abuts against the folded surface of the carton body 1.

[0036] The sidewall bonding assembly 6 includes a bonding vertical plate 61, an elastic tension band 62, and a butt guard plate 63. The bonding vertical plate 61 is tightly bonded to the outside of the carton body 1. The elastic tension band 62 is fixedly connected to the top of the bonding vertical plate 61, and the butt guard plate 63 is fixedly connected to the outside of the elastic tension band 62.

[0037] The protective plate 63 forms a bidirectional compression structure with the top plate 54 through the folded surface of the carton body 1.

[0038] On the opposite sides of the vertical plate 61 and the F-shaped edge support 3, there are magnetic blocks 7 that attract each other, and the magnetic blocks 7 on the opposite sides of the vertical plate 61 and the F-shaped edge support 3 are irregularly shaped magnets.

[0039] The opposite side of the F-shaped edge support 3 is connected by a turnbuckle 8 by a rope.

[0040] The interior of the carton body 1 is also equipped with a horizontal support rod 9, the two ends of which are inserted into the interior of the F-shaped edge support bracket 3.

[0041] The usage process of the non-compression stacking packaging carton in this application embodiment is roughly as follows:

[0042] Unfold the carton body 1 to form its shape, ensuring the four walls and bottom are folded in place. Remove the F-shaped edge support bracket 3 and the hollow positioning frame 2. Slide the hollow positioning frame 2 onto the outside of the F-shaped edge support bracket 3 to initially form a retractable support frame 4. Insert the assembled F-shaped edge support bracket 3 and the hollow positioning frame 2 into the inside of the carton body 1, ensuring its outer side is flush with the four walls of the carton. Stretch the F-shaped edge support bracket 3 to its fully unfolded state, ensuring it is tightly against the inner wall of the carton to enhance lateral pressure resistance. Install horizontal support rods 9 between the F-shaped edge support brackets 3, inserting both ends into the pre-drilled holes in the brackets to form a horizontal reinforcement structure. Fix the support frame 4 to the top of the hollow positioning frame 2, ensuring it is placed horizontally. Rotate the handle 51 of the top assembly 5 to drive the lifting screw 52 to move upward, pushing the top plate 54 against the folded surface of the top of the carton through the thrust bearing 53. During the magnetic attraction process, the vertical plate 61 of the side wall bonding component 6 is attached to the outside of the carton and aligned with the internal F-shaped edge support 3. Utilizing the irregular magnetic properties of the magnetic block 7, the vertical plate 61 and the F-shaped edge support 3 are automatically attracted to each other, ensuring that the inner and outer walls are clamped tightly. The connecting protective plate 63 is connected by the elastic tension band 62 to further tighten the external components and prevent displacement during transportation. The connecting protective plate 63 is attached to the folded surface of the carton by the tension of the elastic tension band 62, and at the same time forms a bidirectional compression with the internal top plate 54, enhancing overall stability. If the carton is large, the turnbuckle 8 can be tightened to tighten the F-shaped edge support 3 on both sides through the rope, further reducing the support spacing to accommodate different carton sizes. After placing the goods, the lid is closed. When stacking multiple layers, the internal support structure distributes the force evenly, preventing the lower layers of the carton from collapsing.

[0043] The beneficial technical effects of the non-compression stacking packaging cartons in this application are roughly as follows:

[0044] This device, through the sliding cooperation of the F-shaped edge support bracket 3 and the hollow positioning frame 2, can be stretched to the inner walls of the four sides of the carton and fit tightly. Combined with the transverse insertion structure of the transverse support rod 9, a three-dimensional support frame 4 is formed, covering the top, sides and both ends of the carton. This allows the device to disperse the stacking stress and avoid local collapse, making it especially suitable for multi-layer stacking of heavy goods. By rotating the handle 51, the height of the top plate 54 can be adjusted to actively press against the top folding surface of the carton. With the bidirectional extrusion structure of the docking protective plate 63, it adapts to cartons of different heights and prevents the top from deforming due to load. In addition, by using external magnetic fixation instead of internal magnetic blocks, the elastic tension band 62 connects the fitting vertical plate 61 and the docking protective plate 63, providing flexible tension on the basis of magnetic attraction to ensure that the support and the carton wall fit firmly.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
