Description

Technical Field

[0001] This utility model relates to the field of packaging box stacking technology, and in particular to a packaging box stacking rack that facilitates classification. Background Technology

[0002] Packaging boxes are primarily designed for convenient transportation, loading, unloading, and warehousing. They are typically made of wooden crates and corrugated solid wood pallets, though tin drums or galvanized iron drums are also used. These boxes are lightweight yet have a high load-bearing capacity and can be customized to the size and specifications of the goods. They are mainly used as a replacement for traditional wooden crates used in transportation. They offer quick assembly, save time and labor, boast exquisite craftsmanship, and provide excellent sealing performance. Furthermore, they conserve significant amounts of wood resources and are an internationally recognized and promoted new type of environmentally friendly packaging product. Honeycomb cardboard boxes not only possess characteristics such as compression resistance, cushioning, and strong shock absorption, providing excellent protection for the contents, but can also be specially treated to achieve waterproof and moisture-proof effects. They can be used in the packaging, stone, home appliance, furniture, electronics and communications, electromechanical, and clothing industries.

[0003] Existing packing box stacking racks primarily rely on casters mounted on their bottoms for movement. Operators can easily move the racks to designated locations within the warehouse simply by pushing them. Once in place, various packing boxes can be neatly placed on the rack shelves for stacking, thus completing basic goods storage operations.

[0004] However, the vertical spacing between each shelf of the stacking rack adopts a fixed structure. Although this standardized design can meet the storage needs of single-size packaging boxes, it has serious shortcomings when dealing with diverse packaging scenarios. When it is necessary to store packaging boxes of different sizes, specifications or shapes, the space utilization rate drops significantly because the layer height spacing cannot be flexibly adjusted according to the actual characteristics of the goods. Excessive fixed spacing causes vertical space waste, while insufficient preset spacing cannot accommodate irregularly shaped packaging, which brings continuous trouble to daily warehouse operation and management. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a packaging box stacking rack that is easy to classify. The shelf height interval is adjustable, and the space can be flexibly arranged according to the characteristics of the packaging boxes, reducing waste, increasing storage capacity, reducing warehousing costs, making the goods stored more neat and reasonable, facilitating retrieval and inventory, reducing the risk of damage to goods, and improving the image of the warehouse.

[0006] The objective of this utility model is achieved through the following technical solution:

[0028] Please refer to Figures 1-5The packaging box stacking rack for easy classification includes a support frame 1 and casters 2 fixedly connected to the lower end of the support frame 1; it also includes a shelf 301 slidably connected to the inner side of the support frame 1, a slide rod 302 fixedly connected to the inner side of the support frame 1, a guide post 303 fixedly connected to one side of the support frame 1, a toothed plate 304 fixedly connected to the inner side of the guide post 303, a rotating shaft 305 rotatably connected to the inner side of the shelf 301, a continuously variable wheel 306 fixedly connected to one side of the rotating shaft 305, a gear 307 fixedly connected to the other side of the rotating shaft 305, a limiting clamp 308 rotatably connected to the support frame 1 for limiting and fixing the continuously variable wheel 306, and a first spring 309 fixedly connected to the inner side of the limiting clamp 308. The toothed plate 304 and the gear 307 mesh and are installed on one side of the support frame 1 as an anti-tipping component.

[0029] In a preferred embodiment of this utility model, by pinching the limiting clamp 308, the limiting clamp 308 is disengaged from the outside of the infinite wheel 306, thereby releasing the fixed limitation on the infinite wheel 306. Then, the shelf 301 is pushed, and the shelf 301 drives the rotating shaft 305 to move. The slide rod 302 guides and limits the shelf 301. The gear 307 rotates on the toothed plate 304, and the toothed plate 304 drives the infinite wheel 306 to rotate, adjusting the shelf 301. Then, the first spring 309 is released, and the first spring 309 drives the limiting clamp 308 to reset, so that the limiting clamp 308 abuts against the infinite wheel 306. The friction between the limiting clamp 308 and the infinite wheel 306 fixes the infinite wheel 306, preventing the infinite wheel 306 from rotating, thereby fixing the shelf 301. Thus, the spacing of the shelf 301 can be adjusted, allowing for flexible arrangement of space according to the characteristics of the packaging box, reducing waste, increasing storage capacity, reducing warehousing costs, and making the goods stored more neatly and reasonably.

[0030] In a preferred embodiment of this utility model, multiple sets of casters 2 are provided, and the array of multiple sets of casters 2 is arranged at the four corners of the bottom of the support frame 1, thereby ensuring that the device remains stable during movement and effectively reducing shaking and bumping.

[0031] In a preferred embodiment of this utility model, a groove is provided on the shelf 301, and the shelf 301 is slidably connected to the outside of the slide rod 302 through the groove. As the shelf 301 moves along the slide rod 302, the slide rod 302 can effectively constrain the movement trajectory of the shelf 301, thereby playing a good guiding and limiting role for the shelf 301 and ensuring that the shelf 301 operates stably within a predetermined range.

[0032] In a preferred embodiment of this utility model, multiple sets of shelves 301 are provided, and multiple sets of shelves 301 are arranged in a linear array inside the support frame 1, thereby increasing the number of packaging boxes that can be placed and improving space utilization.

[0033] In a preferred embodiment of this utility model, the anti-tipping assembly includes a guide plate 401 fixedly connected to one side of the support frame 1, a slider 402 slidably connected to the inner side of the guide plate 401, a connecting rod 403 rotatably connected to one side of the slider 402, a support column 404 rotatably connected to the inner side of the connecting rod 403, a support block 405 rotatably connected to the inner side of the support column 404, a connecting block 406 fixedly connected to one side of the support frame 1, a second spring 407 fixedly connected to the inner side of the slider 402, a movable block 408 fixedly connected to one side of the second spring 407, a limiting block 409 fixedly connected to one side of the movable block 408, a pull rod 410 fixedly connected to one side of the movable block 408, and a pull ring 411 rotatably connected to the inner side of the pull rod 410, and a support block. 405 is rotatably connected to the inner side of the connecting block 406. By pulling the pull ring 411, the pull ring 411 drives the pull rod 410. The pull rod 410 drives the movable block 408 to slide in the second groove inside the slider 402. The sliding of the movable block 408 will compress or stretch the second spring 407, and at the same time drive the limiting block 409 fixedly connected to one side of the movable block 408 to move, so that the limiting block 409 is disengaged from the third groove on the support frame 1, releasing the locking restriction on the slider 402. At this time, the slider 402 can slide more freely inside the guide plate 401. The slider 402 drives the connecting rod 403 to move, and the connecting rod 403 drives the support column 404 to move, finally causing the support block 405 to de-contact or re-contact the ground, realizing the support or de-support state of the stacking rack.

[0034] In a preferred embodiment of this utility model, a second groove is provided on the slider 402, and the movable block 408 is slidably connected to the inner side of the slider 402 through the second groove, thereby providing a reliable guiding function for the movable block 408 and effectively limiting the movement range of the movable block 408, ensuring that it can only move within a specific area, thus achieving a good guiding and limiting effect.

[0035] In a preferred embodiment of this utility model, a groove 3 is provided on the support frame 1, and the limiting block 409 is engaged with the inner side of the support frame 1 through the groove 3. Thus, the limiting block 409 can effectively fix the associated slider 402 and prevent the slider 402 from shifting unexpectedly.

[0036] In a preferred embodiment of this utility model, multiple sets of guide plates 401, sliders 402, connecting rods 403, support columns 404, support blocks 405, and connecting blocks 406 are provided. These multiple sets of guide plates 401, sliders 402, connecting rods 403, support columns 404, support blocks 405, and connecting blocks 406 are arrayed at the four corners of the support frame 1, thereby enhancing the overall structural strength and stability of the stacking rack.

[0037] During operation, by pinching the limiting clamp 308, the limiting clamp 308 is disengaged from the outer side of the infinite wheel 306, thereby releasing the fixed limitation on the infinite wheel 306. Then, the shelf 301 is pushed, and the shelf 301 drives the rotating shaft 305 to move. The slide rod 302 guides and limits the shelf 301. The gear 307 rotates on the gear plate 304, and the gear plate 304 drives the infinite wheel 306 to rotate, adjusting the shelf 301. Then, the first spring 309 is released, and the first spring 309 drives the limiting clamp 308 to reset, so that the limiting clamp 308 abuts against the infinite wheel 306. The friction between the limiting clamp 308 and the infinite wheel 306 fixes the infinite wheel 306, preventing it from rotating, thereby fixing the shelf 301. Thus, the spacing of the shelf 301 can be adjusted flexibly according to the characteristics of the packaging box. By arranging space, reducing waste, increasing storage capacity, and lowering warehousing costs, goods can be stored more neatly and rationally. By pulling the pull ring 411, the pull ring 411 drives the pull rod 410, which in turn drives the movable block 408 to slide in the groove two inside the slider 402. The sliding of the movable block 408 compresses or stretches the second spring 407, and at the same time drives the limit block 409 fixedly connected to one side of the movable block 408 to move, so that the limit block 409 disengages from the groove three on the support frame 1, releasing the locking restriction on the slider 402. At this time, the slider 402 can slide more freely inside the guide plate 401. The slider 402 drives the connecting rod 403 to move, and the connecting rod 403 drives the support column 404 to move, ultimately causing the support block 405 to de-contact or re-contact the ground, realizing the support or de-support state of the stacking rack.

[0038] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.

[0039] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
