[0002] During the stacking process of traditional cartons, since the bundling straps are placed between the cartons, gaps are formed between the cartons, which easily leads to unstable stacking, easy tilting, easy collapse or displacement, thereby increasing the probability of cargo damage and transportation costs, and even posing potential safety hazards. Content of the Utility Model

[0003] Aiming at the technical problems existing in the prior art, the utility model provides a corrugated carton convenient for stable stacking to solve the problems that during the stacking process of cartons, due to the bundling straps being placed between the cartons, gaps are formed between the cartons, which easily leads to unstable stacking, easy tilting, easy collapse or displacement.

[0004] The technical solution for the utility model to solve the above technical problems is as follows: A corrugated carton convenient for stable stacking, including:

[0005] A carton;

[0006] A bearing pad arranged at the bottom of the carton, and a receiving groove is formed inside the bearing pad;

[0007] At least four bundling assemblies, and at least four bundling assemblies are respectively arranged on adjacent sides of the bearing pad. Among them, each bundling assembly includes a bundling strap, and the bundling strap is bundled along the outer contour of the carton to form a cross-shaped bundling shape on the top of the carton;

[0008] A cross-shaped limiting groove is formed at the bottom of the bearing pad.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1) By arranging a bearing pad at the bottom of the carton and arranging a bundling assembly on the bearing pad, bundling the carton with the bundling strap, and adjusting the bundling method of the bundling strap to form a cross-shaped bundling shape, a limiting groove matching the cross shape is arranged at the bottom of the bearing pad. When the cartons are stacked, the bundling strap can be embedded in the limiting groove, making the contact between the stacked cartons closer and more tightly fitted. This not only ensures the accuracy of the position of the cartons during stacking, but also enables the cartons to have a certain positioning stacking function, avoiding displacement or misalignment, improving the stacking effect, reducing the risk of cargo damage and safety accidents, and thus improving the safety and reliability during transportation.

[0011] Based on the above technical solutions, the utility model can be further improved as follows.

[0012] Further, each of the bundling assemblies further includes a ratchet wheel, a pawl, a fixing disk, a main shaft, a winding bin, an opening, a spring, and at least four fastening structures for locking the bundling belt after bundling the cardboard box onto the bearing pad. The winding bin is fixed on the side of the bearing pad, and the opening is formed at the top of the winding bin.

[0013] Further, the fixing disk is fixed on one side of the winding bin, the ratchet wheel is located on one side of the fixing disk, and the main shaft is located inside the winding bin. Wherein, one end of the main shaft penetrates through the winding bin and the fixing disk and is coaxially and fixedly connected to the ratchet wheel, and the other end of the main shaft is rotatably connected to the inner wall of the winding bin through a rotating shaft. One end of the bundling belt is wound around the outside of the main shaft, and the other end passes through the opening of the winding bin.

[0014] Further, the spring is located inside the winding bin and is arranged at the other end of the main shaft. The pawl abuts against one side of the ratchet wheel and is rotatably connected to the fixing disk through a rotating shaft, and a torsion spring is further arranged between the pawl and the fixing disk.

[0015] The beneficial effect of adopting the above further scheme is that the process of bundling the cardboard box is simplified, the operation efficiency and convenience are improved. The operator only needs to pull out the bundling belt from the opening of the winding bin, and then bundle it along the outer contour of the cardboard box to form an inverted "U" - shaped path. In addition, during the bundling process, one end of the main shaft drives the ratchet wheel to rotate, while the other end of the main shaft drives the spring to tighten, storing elastic potential energy in the spring. When the length of the bundling belt unrolled from the winding bin outward matches the size of the bundled cardboard box, the pawl can be stuck on the ratchet wheel to prevent the spring from driving the main shaft to rotate in the reverse direction to retract the bundling belt, thereby stabilizing the bundling belt. When retracting the bundling belt, only need to drive the pawl to rotate along the direction away from the ratchet wheel, and the torque force stored in the spring will drive the main shaft to rotate in the reverse direction to roll the bundling belt back into the winding bin for the next use. This scheme simplifies the bundling operation, improves the efficiency, and is easy to implement and operate.

[0016] Further, at least four of the fastening structures are respectively arranged on two adjacent sides of the bearing pad. Wherein, each of the fastening structures includes a through - hole and a fastening bolt. The through - hole penetrates from the top of the bearing pad and extends to the side, presenting an "L" shape. One end of the fastening bolt is screwed onto the bearing pad through a thread and is located on one side of the through - hole.

[0017] The beneficial effect of adopting the above further scheme is that the operator can easily take out the bundling belt from the winding bin, bundle it along the outer contour of the cardboard box, then pass the bundling belt through the through - hole, and then, by rotating the fastening bolt, press it against the bundling belt in the through - hole, thereby firmly fixing the bundled bundling belt on the bearing pad, ensuring that the bundling belt will not loosen or slip during transportation and handling, thus enhancing the stability and protection of the cardboard box.

[0018] Further, the bearing pad is made of silica gel.

[0019] The beneficial effects of adopting the above further solution are that the silicone surface usually has good friction characteristics, which can effectively prevent the strapping band from sliding or loosening on the bearing pad, thereby increasing the stability and safety of strapping, being able to withstand high pressure without being easily deformed or damaged, and at the same time can also play a buffering role for the carton.

[0020] Further, anti-slip tooth grooves are respectively provided on both sides of the strapping band.

[0021] The beneficial effects of adopting the above further solution are that the anti-slip tooth groove design can increase the friction between the strapping band and the surface of the carton, thereby ensuring that the strapping band is more firmly fixed on the carton during the bundling process, preventing sliding or loosening. At the same time, the tooth grooves can also effectively increase the friction between the strapping band and the bearing pad, reducing the occurrence of displacement or misalignment during the stacking of cartons.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0031] During the stacking process of traditional cartons, since the binding straps are placed between the cartons, gaps are formed between the cartons, which easily leads to unstable stacking, easy tilting, easy collapse or displacement, thus increasing the probability of cargo damage and transportation costs, and even posing potential safety hazards. In response to this, the utility model inventor has proposed a corrugated carton that is convenient for stable stacking to solve the above problems.

[0032] The present utility model provides the following preferred embodiments

[0033] As Figures 1 - 6 shown, the corrugated carton 10 convenient for stable stacking includes:

[0034] A carton 10;

[0035] A bearing pad 20 provided at the bottom of the carton 10, and a receiving groove 201 is formed inside the bearing pad 20;

[0036] At least four binding assemblies 30, and at least four binding assemblies 30 are respectively provided on two adjacent sides of the bearing pad 20. Among them, each binding assembly 30 includes a binding strap 310, and the binding strap 310 is bundled along the outer contour of the carton 10 and forms a cross-shaped bundling shape on the top of the carton 10;

[0037] A cross-shaped limiting groove 40 is formed at the bottom of the bearing pad 20;

[0038] By providing a bearing pad 20 at the bottom of the carton 10 and arranging a binding assembly 30 on the bearing pad 20, the carton 10 is bundled by the binding strap 310. By adjusting the bundling method of the binding strap 310, a cross-shaped bundling shape is formed. A limiting groove 40 matching the cross shape is provided at the bottom of the bearing pad 20. When the cartons 10 are stacked, the binding strap 310 can be embedded in the limiting groove 40, so that the contact between the stacked cartons 10 is closer and the fit is tighter. This not only ensures the accuracy of the position of the cartons 10 during stacking, but also enables the cartons 10 to have a certain positioning and stacking function during stacking, avoiding the occurrence of displacement or misalignment, improving the stacking effect, reducing the risk of cargo damage and safety accidents, and thus improving the safety and reliability during transportation.

[0039] In this embodiment, as Figures 1 - 6 shown, each binding assembly 30 further includes a ratchet 320, a pawl 330, a fixed disk 340, a main shaft 350, a winding bin 360, an opening 370, a spring 380, and at least four fastening structures 390 for locking the binding strap 310 after bundling the carton 10 on the bearing pad 20. The winding bin 360 is fixed on the side of the bearing pad 20, and the opening 370 is formed at the top of the winding bin 360;

[0040] The fixed disk 340 is fixed on one side of the winding bin 360, the ratchet 320 is located on one side of the fixed disk 340, and the main shaft 350 is located in the winding bin 360, wherein one end of the main shaft 350 passes through the winding bin 360 and the fixed disk 340 and is coaxially fixedly connected to the ratchet 320, and the other end of the main shaft 350 is rotatably connected to the inner wall of the winding bin 360 through a rotating shaft, and one end of the strapping belt 310 is wound around the outside of the main shaft 350, and the other end passes through the opening 370 of the winding bin 360;

[0041] The mainspring 380 is located in the winding bin 360 and is disposed at the other end of the main shaft 350. The pawl 330 abuts against one side of the ratchet wheel 320 and is rotatably connected to the fixed disk 340 via a rotating shaft. A torsion spring is also disposed between the pawl 330 and the fixed disk 340.

[0042] Therefore, the above scheme simplifies the process of bundling the carton 10, improves the operating efficiency and convenience, and the operator only needs to pull out the strapping belt 310 from the opening 370 of the winding bin 360, and then bundle it along the outer contour of the carton 10 to form an inverted "凵"-shaped path. In addition, during the bundling process, one end of the main shaft 350 drives the ratchet 320 to rotate, and the other end of the main shaft 350 drives the spring 380 to tighten, storing the elastic potential energy in the spring 380. When the strapping belt 310 is rolled out from the winding bin 360 to a length that matches the bundling, After the size of the carton 10 is adjusted, the pawl 330 can be stuck on the ratchet 320, preventing the spring 380 from driving the main shaft 350 to rotate in the opposite direction to retract the strapping strap 310, thereby stabilizing the strapping strap 310. When retracting the strapping strap 310, it is only necessary to drive the pawl 330 to rotate in the direction away from the ratchet 320, and the torque force stored in the spring 380 will drive the main shaft 350 to rotate in the opposite direction, and rewind the strapping strap 310 into the winding bin 360 for next use. This solution simplifies the strapping operation, improves efficiency, and is easy to implement and operate.

[0043] In this embodiment, Figures 1 - 6 As shown, at least four fastening structures 390 are respectively arranged on two adjacent sides of the bearing pad 20, wherein each fastening structure 390 includes a through hole 391 and a fastening bolt 392, the through hole 391 penetrates from the top of the bearing pad 20 and extends to the side to present an L shape, one end of the fastening bolt 392 is screwed on the bearing pad 20 through a thread and is located on one side of the through hole 391;

[0044] The operator can easily take out the bundling strap 310 from the winding bin 360, bundle it along the outer contour of the carton 10, then pass the bundling strap 310 through the perforation 391. Subsequently, by rotating the fastening bolt 392, it is pressed against the bundling strap 310 in the perforation 391, thereby firmly fixing the bundled bundling strap 310 on the bearing pad 20, ensuring that the bundling strap 310 will not loosen or slip during transportation and handling, thus enhancing the stability and protection of the carton 10.

[0045] In this embodiment, as Figures 1 - 6 shown, the bearing pad 20 is made of silica gel. The silica gel surface usually has good friction characteristics, which can effectively prevent the bundling strap 310 from sliding or loosening on the bearing pad 20, thereby increasing the stability and safety of bundling. It can withstand high pressure without being easily deformed or damaged, and at the same time can also play a buffering role for the carton 10.

[0046] In this embodiment, as Figures 1 - 6 shown, anti-slip tooth grooves are respectively provided on both sides of the bundling strap 310. The anti-slip tooth groove design can increase the friction between the bundling strap 310 and the surface of the carton 10, thereby ensuring that the bundling strap 310 is more firmly fixed on the carton 10 during the bundling process to prevent sliding or loosening. At the same time, the tooth grooves can also effectively increase the friction between the bundling strap 310 and the bearing pad 20, reducing the occurrence of displacement or misalignment during the stacking of the cartons 10.

[0047] The specific working process of the present utility model is as follows:

[0048] (1) Bundling

[0049] First, place the carton 10 into the receiving groove 201 of the bearing pad 20. At this moment, the operator pulls out the bundling strap 310 from the opening 370 of the winding bin 360, then bundles it along the outer contour of the carton 10 to form an inverted "U" - shaped path, and then lets the bundling strap 310 pass through the perforation 391. Subsequently, by rotating the fastening bolt 392, it is pressed against the bundling strap 310 in the perforation 391, thereby firmly fixing the bundled bundling strap 310 on the bearing pad 20.

[0050] (2) Stacking the cartons 10

[0051] Place the bearing pad 20 on top of another carton 10, and let the lower bundling strap 310 be embedded in the limiting groove 40 of the upper bearing pad 20.

[0052] (3) Winding the bundling strap 310

[0053] Drive the ratchet pawl 330 to rotate away from the ratchet wheel 320, and the torque force stored in the spring 380 will drive the main shaft 350 to rotate in the reverse direction, rewind the strapping 310 into the winding bin 360 for the next use.
