Description

Technical Field

[0001] This utility model relates to the field of turnover box technology, and more specifically to a logistics turnover box that is combined with a pallet. Background Technology

[0002] In modern logistics, warehousing, and supply chain management, reusable containers are widely used as logistics carriers in the storage, sorting, transportation, and distribution of parts and components. They play a crucial role in protecting goods, improving handling efficiency, and realizing unitized logistics.

[0003] Currently, most logistics turnover boxes on the market are designed independently, meaning that the box body and the pallet are separate. During operation, empty turnover boxes need to be stacked on the pallet first, and then the goods are loaded. After the goods arrive, the entire stack of turnover boxes needs to be unloaded from the pallet one by one, or a forklift is used to move the entire pallet group.

[0004] Existing turnover boxes are simply stacked on pallets. There is a lack of reliable connection and positioning mechanism between the bottom of the turnover box and the pallet. During long-distance transportation or forklift handling, especially when subjected to vibration, impact or sharp turns, the box and the pallet are prone to relative slippage, which may even cause the entire stack to overturn, resulting in damage to the goods inside the box and posing a serious safety hazard. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pallet-combined logistics turnover box to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a pallet-integrated logistics turnover box, including a turnover box mechanism, a pallet mechanism at the bottom of the turnover box mechanism, the pallet mechanism being connected to the turnover box mechanism via a connecting component, the turnover box mechanism including a first turnover box and a second turnover box, the first turnover box and the second turnover box being identical on all sides and inside, the pallet mechanism including a pallet one and a pallet two, the supporting feet of pallet one being distributed in a ring around the perimeter for carrying light items; the supporting feet of pallet two being distributed in a rectangular array for carrying heavy items.

[0007] As a further embodiment of this utility model, the connecting component includes cylinders disposed at the four corners of the bottom of the first turnover box for supporting the first turnover box. The bottom of the cylinder is tapered, and the tip of the tapered cylinder faces away from the first turnover box. The upper surface of the tray is provided with slots at the four corners that cooperate with the cylinders.

[0008] As a further embodiment of this utility model, the slot is a conical hole structure that matches the conical shape of the bottom of the cylinder, and the diameter of the slot gradually decreases from the opening end to the bottom, forming a wedge-tight fit with the cylinder.

[0009] As a further embodiment of this utility model, the connecting component includes a plurality of inserts disposed at the bottom of the second turnover box, each insert having an inclined surface on its outer side and the insert being conical in shape. The cylinder of the first turnover box and the inserts of the second turnover box can be used to combine and connect with the pallet. The pallet mechanism also includes an insert hole disposed at the bottom of the second turnover box, the upper surface of which is provided with a hole that mates with the inserts.

[0010] As a further embodiment of this invention, the inner wall of the insertion hole is configured as a conical surface that matches the inclined surface of the insertion post.

[0011] As a further embodiment of this utility model, the insertion post and the second turnover box are detachably connected by screws, and the plurality of insertion holes are distributed in a matrix-like staggered manner on the upper surface of the second turnover box and are inserted into the insertion post.

[0012] As a further embodiment of this utility model, a rigid plastic bushing is embedded in the inner wall of the slot, and the inner wall of the bushing fits into the conical structure of the cylinder.

[0013] As a further embodiment of this invention, the outer side of the cylinder is provided with a plurality of equally spaced grooves.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model solves the problem that traditional turnover boxes and pallets cannot cooperate with each other by matching the conical cylinder of the first turnover box with the conical slot and the conical insert of the second turnover box with the conical insert. This achieves precise positioning and stable connection between the turnover box mechanism and the pallet mechanism.

[0016] 2. This utility model adapts to pallet type 1 by using a first turnover box to adapt to pallet type 1 and a second turnover box to adapt to pallet type 2, and adopts a detachable design, thus achieving full coverage adaptation to mainstream pallet types in logistics scenarios.

[0017] 3. This utility model effectively reduces the concentration of local stress in the second turnover box by dispersing the load through matrix-type inserts, thereby improving the overall load-bearing capacity of the second turnover box and adapting to the cargo transfer needs of various scenarios from light load to heavy load.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Reference Figures 1-4 This utility model provides a pallet-combined logistics turnover box, including a turnover box mechanism 1. The turnover box mechanism 1 includes a first turnover box 101 and a second turnover box 102. The bottom four corners of the first turnover box 101 are provided with cylinders 5 for supporting the first turnover box 101. The bottom of the cylinders 5 is conical, and the tip of the cone is facing away from the first turnover box 101.

[0025] Pallet mechanism 2 includes pallet one 201 and pallet two 202. The supporting feet of pallet one 201 are distributed in a ring around the perimeter for carrying light items. When carrying light, large, or evenly distributed goods (such as empty boxes, bulky foam, etc.), the ring support provides uniform edge support force, effectively preventing excessive bending deformation of the pallet surface during handling and ensuring operational stability. The supporting feet of pallet two 202 are distributed in a rectangular array for carrying heavy items. The rectangular array of feet can efficiently distribute and transfer the weight of the goods above, especially concentrated loads, through multiple support points. This structure greatly improves the pallet's bending resistance and overall load-bearing strength, enabling it to withstand the pressure of heavy goods.

[0026] The bottom of the second turnover box 102 is provided with multiple inserts 7, and each insert 7 has an inclined surface 8 on its outer side. The insert 7 is cone-shaped. The cylinder 5 of the first turnover box 101 and the insert 7 of the second turnover box 102 can be used to connect with the pallet.

[0027] In this embodiment, a pallet mechanism 2 is provided at the bottom of the turnover box mechanism 1. The pallet mechanism 2 includes a pallet 201 at the bottom of the first turnover box 101. The upper surface of the pallet 201 and the four corners are provided with slots 3 that cooperate with the cylinders 5. The slots 3 are conical holes that match the conical shape of the bottom of the cylinders 5. The diameter of the slots 3 gradually decreases from the opening end to the bottom and forms a wedge-tight fit with the cylinders 5. When the cylinders 5 are inserted into the slots 3, the conical structure guides the cylinders 5 to be inserted along the center line of the conical hole through the self-centering effect, ensuring that the installation position of the first turnover box 101 on the pallet 201 is accurate and without deviation. At the same time, the tight fit between the conical surfaces forms a circumferential limit, which effectively restricts the horizontal displacement (such as left and right sliding or back and forth movement) of the first turnover box 101 relative to the pallet during handling and stacking, and avoids the goods from tipping over or being damaged by collision due to displacement.

[0028] In addition, the pallet mechanism 2 also includes a second pallet 202 located at the bottom of the second turnover box 102. The upper surface of the second pallet 202 is provided with an insertion hole 6 that mates with the insertion post 7. The inner wall of the insertion hole 6 is set as a conical surface that matches the inclined surface 8 of the insertion post 7. The conical structure of the insertion post 7 and the inclined surface 8 have guiding properties. When inserted, the inclined surface 8 and the conical surface of the insertion hole 6 fit together. By utilizing the self-centering effect of the conical surface, the insertion post 7 is guided to be accurately inserted into the insertion hole 6. No manual precise alignment is required, which improves the efficiency and speed of the combination of the turnover box and the pallet. At the same time, the tight fit between the conical surfaces forms a circumferential constraint, which completely restricts the horizontal sliding of the second turnover box 102 relative to the second pallet 202. Even under complex working conditions such as rapid forklift transfer and bumpy road surface, the turnover box can maintain a stable position and avoid damage from collisions.

[0029] Among them, the conical fit between the insert post 7 and the insertion hole 6 is a wedge-tight structure. The weight of the second turnover box 102 and the goods will be converted into a radial locking force along the conical surface. The deeper the insert post 7 is inserted into the insertion hole 6, the tighter the conical surface fits, and the greater the locking force, forming a tighter anti-loosening effect, which solves the problem of easy loosening of the traditional straight post and round hole fit.

[0030] The insert post 7 is detachably connected to the second turnover box 102 by screws. Multiple insertion holes 6 are distributed in a matrix staggered manner on the upper surface of the second turnover box 102 and are inserted into the insert post 7. The multiple insert posts 7 are distributed in a matrix staggered manner (adapting to the insertion hole 6 layout of the second pallet 202). The number and position of the insert posts 7 can be flexibly adjusted according to the weight distribution and center of gravity of the goods in the second turnover box 102 (such as increasing the number of insert posts 7 in heavy-load areas and adding insert posts 7 in areas with a shifted center of gravity). This allows the load of the second turnover box 102 to be evenly transferred to the second pallet 202 through the conical surface of each insert post 7, avoiding local stress concentration that could cause deformation of the bottom of the pallet or the second turnover box 102. This adapts to the multi-scenario cargo transfer needs from light load to heavy load.

[0031] In addition, the insert 7 is detachably connected to the bottom of the second turnover box 102 by screws. When the inclined surface 8 of the insert 7 is worn or deformed due to long-term use, the insert 7 can be replaced separately without replacing the entire turnover box, thus reducing maintenance costs. At the same time, by replacing the insert 7 with different tapers and lengths, the second turnover box 102 can be adapted to other types of plastic pallets (such as zigzag pallets and grid pallets) except for pallet 202. Stable combination can be achieved simply by opening the insertion hole 6 on the pallet that matches the tapered surface of the insert 7.

[0032] A rigid plastic bushing is embedded in the inner wall of the slot 3. The inner wall of the bushing fits into the conical structure of the cylinder 5. The rigid plastic bushing embedded in the inner wall of the slot 3 (preferably made of polyamide or polyoxymethylene) isolates the cylinder 5 from direct friction with the tray 201, preventing wear and fraying of the inner wall of the slot 3 due to long-term use, thus significantly improving the service life of the tray. On the other hand, the precise fit between the inner wall of the bushing and the conical structure of the cylinder 5 ensures that the mating gap remains stable even after long-term insertion and removal, preventing a decrease in positioning accuracy due to wear and ensuring long-term reliable mating performance between the first turnover box 101 and the tray 201.

[0033] In this embodiment, the outer side of the cylinder 5 is provided with a plurality of equally spaced grooves 4. After the cylinder 5 is inserted into the slot 3, the radial locking force generated by the conical surface will cause the cylinder 5 to bear circumferential compressive stress. The setting of the grooves 4 can disperse the concentrated stress along the slot direction to the overall structure of the cylinder 5, avoiding cracking and deformation of the cylinder 5 (especially the conical part) due to local stress concentration. During the long-term insertion and extraction process between the first turnover box 101 and the tray 201, the conical surface of the cylinder 5 and the hard plastic bushing in the slot 3 will generate tiny friction debris. If the debris accumulates between the conical surfaces, it will cause the fit gap to increase, affecting the positioning accuracy and locking effect. The grooves 4 can serve as a debris collection groove to accommodate the debris generated by friction, prevent the debris from being trapped between the conical surfaces, ensure the long-term stability of the fit accuracy between the cylinder 5 and the bushing, and extend the service life of the fit structure.

[0034] It should be noted that the insert 7 and the cylinder 5 will not affect the normal placement and use of the turnover box mechanism 1.

[0035] The working principle of this utility model is as follows: When the first turnover box 101 is hoisted to the top of the pallet 201, the conical tip of the cylinder 5 first enters the opening end of the slot 3. Utilizing the self-centering effect of the conical structure, the cylinder 5 automatically corrects its position along the center line of the conical hole, achieving precise insertion without the need for manual alignment, thus ensuring that the first turnover box 101 is not offset in the installation position of the pallet 201.

[0036] Based on the weight and center of gravity distribution of the goods in the second turnover box 102, the number and position of the inserts 7 are first determined. The inserts 7 are fixed to the bottom of the turnover box with screws. The turnover box with the inserts 7 installed is hoisted above the pallet 202, so that each insert 7 is aligned with the matrix-distributed insertion holes 6 on the pallet. When the turnover box is lowered, the conical tip of the insert 7 enters the opening end of the insertion hole 6. Utilizing the self-centering guiding effect of the inclined surface 8 and the conical surface of the insertion hole 6, the insert 7 automatically corrects its position and is accurately inserted into the insertion hole 6 without the need for manual alignment, thus improving the assembly efficiency.

[0037] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
