Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a green and environment-friendly high-strength corrugated paper packaging box. Background Art

[0002] Corrugated paper boxes are the most widely used packaging products, and their usage has always been the first among all kinds of packaging products. Including calcium plastic corrugated paper boxes, for more than half a century, corrugated paper boxes have gradually replaced wooden boxes and other transport packaging containers with their superior performance and good processing performance, becoming the main force of transport packaging. In addition to protecting goods, facilitating storage and transportation, they also play a role in beautifying and promoting goods.

[0003] Chinese patent publication No. C1-8220810267U discloses a green and environmentally friendly high-strength corrugated paper packaging box, which relates to the technical field of packaging boxes, including a composite corrugated paper shell, a plastic inner shell is arranged on the inner wall of the composite corrugated paper shell, and four groups of limit blocks are arranged at equal intervals on the side surface of the inner wall of the plastic inner shell, and a group of limit blocks are fixedly connected by a sliding track, and two bracket sleeves are slidably connected on the surface of the sliding track to place valuables on the top of the load-bearing plate;

[0004] The above patent mainly controls the two connecting brackets through the protective plug plate and the connecting shaft to push the two bracket sleeves to slide on the surface of the sliding track respectively. The bracket sleeves will generate elasticity through the spring to cushion the shock, which is a shock-absorbing mechanism. There are four groups of this mechanism, which can cushion and pull the composite corrugated paper inner box, thereby effectively reducing the shaking of medium and upper amplitudes.

[0005] However, although the method in the above patent can improve the protection of internal items, when transporting round objects, such as glass jars, ceramic jars and other cylindrical objects, the contact with these cylindrical objects is only the arc apex of the cylinder, and the contact area is small. Therefore, it is easy to become unstable when hit. At the same time, the shape of the glass or ceramic jar body in the prior art mostly has side handles, and irregular objects are prone to appear. Therefore, the packaging box in the above patent has great limitations and low applicability. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a green and environmentally friendly high-strength corrugated paper packaging box so as to solve the technical problems mentioned in the above background technology.

[0007] The above technical objectives of the utility model are achieved through the following technical solutions:

[0008] A green and environment-friendly high-strength corrugated paper packaging box, comprising a cardboard bottom plate, a cardboard top cover, four cardboard side walls, four support members and a number of prefabricated corrugated plates;

[0009] Positioning grooves are provided at the four corners of the cardboard bottom plate, positioning insertion holes are provided at the two groove walls of the positioning grooves, and a number of fixing inserts are provided at the upper end of the cardboard bottom plate;

[0010] The support member includes a right-angle folding plate, a support rod is fixedly connected to the inner side of the right-angle folding plate, fixing pins are provided on both sides of the bottom end of the support rod, a number of uniformly distributed positioning pins are provided on both sides of the support rod, and a locking hole is provided at the top end of the support rod;

[0011] Locking pins are provided at the four corners of the bottom end of the cardboard top cover.

[0012] Furthermore, a number of fixing grooves are provided on both sides of the cardboard side wall, the positions of the fixing grooves correspond to the positioning pins one by one, and the sizes of the fixing grooves are equal to the sizes of the positioning pins.

[0013] Furthermore, the locking pin is matched with the locking hole, and a rubber layer is wrapped around the outer peripheral side of the locking pin.

[0014] Furthermore, an extension plate is provided at a position near the edge of the top of the cardboard bottom plate, and the extension plate is attached to the cardboard side wall after the packaging box is assembled.

[0015] Furthermore, connecting insertion holes are provided at the bottom end of the prefabricated corrugated plate, and the connecting insertion holes are matched with the fixing inserts, and the prefabricated corrugated plates are provided in a variety of different shapes.

[0016] Furthermore, the cardboard bottom plate, the cardboard top cover and the support member are all made of plastic material, and grooves are provided at the centers of the four corners at the bottom end of the cardboard bottom plate.

[0017] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0018] 1. For this green and environment-friendly high-strength corrugated paper packaging box, during transportation, it is inevitable that various parts of the cardboard box will be collided. However, the object to be transported will be supported by the prefabricated corrugated plates, which can effectively avoid the problem that the object to be transported is damaged due to impact. At the same time, the various components of the packaging box are assembled by splicing. Therefore, when the outer wall of the packaging box is damaged due to impact, only the damaged components need to be replaced to achieve the continuous use of the packaging box and reduce the loss of the packaging box;

[0019] 2. The green environmental protection type high-strength corrugated paper packaging box is provided with connecting jacks for installing prefabricated corrugated boards at the top of the fixed inserts, achieving the effect of fixing the prefabricated corrugated boards. Furthermore, by setting prefabricated corrugated boards of different shapes, the packaging box can fix objects of different shapes, including but not limited to spheres, cylinders, and cube items.

[0020] 3. For the green environmental protection type high-strength corrugated paper packaging box, since the carton bottom board, the carton upper cover, and the support members are all made of plastic material, the corners at the bottom, upper end, and side of the packaging box all have high strength. Therefore, when under pressure, the possibility of the packaging box deforming can be effectively reduced. And because the right-angle folding plates of the support members can effectively protect both sides of the carton side wall, and the extension plates and the above-mentioned support strips can support the upper and lower ends of the carton side wall, the possibility of the carton side wall being damaged can be effectively reduced, and thus the safety of the packaging box can be effectively improved.

[0032] Example:

[0033] Refer to Figure 1 - Figure 1 -8, a green and environment-friendly high-strength corrugated paper packaging box disclosed by the present utility model includes a bottom board 1 of the paper box, an upper cover 2 of the paper box, four side walls 3 of the paper box, four support members 4 and a plurality of prefabricated corrugated boards 5;

[0034] Positioning grooves 11 are provided at the four corners of the bottom board 1 of the paper box, positioning jacks 12 are provided at the two groove walls of the positioning grooves 11, and a plurality of fixing inserts 13 are provided at the upper end of the bottom board 1 of the paper box;

[0035] The support member 4 includes a right-angle folding plate 41, a support rod 42 is fixedly connected to the inner side of the right-angle folding plate 41, fixing pins 43 are provided on both sides of the bottom end of the support rod 42, a plurality of uniformly distributed positioning rods 44 are provided on both sides of the support rod 42, and a locking hole 45 is provided at the top end of the support rod 42;

[0036] Locking pins 21 are provided at the four corners of the bottom end of the upper cover 2 of the paper box.

[0037] In this embodiment, as Figure 1 , a sealed packaging box is jointly formed by the bottom board 1 of the paper box, the upper cover 2 of the paper box, four side walls 3 of the paper box and four support members 4;

[0038] As Figure 2, by inserting the fixing pins 43 on both sides of the bottom end of the support member 4 into the jacks opened on the two groove walls of the positioning groove 11, the purpose of fixing the support member 4 to the bottom plate 1 of the carton is achieved, and both sides of the carton side wall 3 are respectively inserted into the opposite sides of two adjacent support members 4, so that the carton side wall 3 is connected to the two adjacent support members 4, thereby achieving the purpose of surrounding the four carton side walls 3 around the upper end of the carton bottom plate 1. When the carton upper cover 2 is buckled on the upper end of the carton side wall 3 and the locking pin 21 is inserted into the four locking holes 45, a sealed packaging carton is formed. When the carton side wall 3 is connected to the two support members 4, the right-angle folding plate 41 in the support member 4 can block both sides of the carton side wall 3, which can make the packaging box neater after assembly, and can also effectively prevent the outside from scraping the corners of the carton side wall 3, thereby achieving the effect of protecting the carton side wall 3 to prevent the carton side wall 3 from folding and flipping, and further achieving the effect of improving the service life of the packaging box;

[0040] At the same time, since it is inevitable to cause collisions to various parts of the carton during transportation, and the object to be transported will be lifted by the prefabricated corrugated board 5, it can effectively avoid the problem that the object to be transported is damaged due to impact. At the same time, the various components of the packaging box are assembled with each other. Therefore, when the outer wall of the packaging box is damaged due to impact, only the damaged parts need to be replaced to achieve the continuous utilization of the packaging box and reduce the loss of the packaging box.

[0041] In a further preferred embodiment of the present invention, as Figure 1 - 8 shown, a plurality of fixing grooves 31 are opened on both sides of the carton side wall 3, the positions of the fixing grooves 31 correspond to the positioning insertion rods 44 one by one, and the sizes of the fixing grooves 31 are equal to the sizes of the positioning insertion rods 44.

[0042] In this embodiment, the fixing grooves 31 are provided to be connected with the positioning insertion rods 44 to achieve the purpose of connecting the carton side wall 3 to the support member 4, thereby achieving the effect of installing the four carton side walls 3 at the edge positions near the upper end of the carton bottom plate 1.

[0044] In this embodiment, since the locking bolt 21 and the locking hole 45 cooperate with each other and the positions correspond one by one, the upper cover 2 of the cardboard box can be connected to the support member 4, and the upper cover 2 of the cardboard box can be supported by the support member 4, thereby improving the stability of the packaging box. And through the setting of the rubber layer, the locking bolt 21 and the locking hole 45 are in interference fit to further improve the stability of the upper cover 2 of the cardboard box after installation, and effectively avoid the detachment of the cardboard box. And as Figure 5 shown, a plurality of support strips are provided at the position near the edge of the bottom end of the upper cover 2 of the cardboard box, which are used to provide a supporting force for the top end of the side wall of the cardboard box, so as to further improve the stability of the side wall 3 of the cardboard box.

[0045] In a further preferred embodiment of the present utility model, as Figure 1 - 8 shown, an extension plate 14 is provided at the position near the edge of the top of the cardboard box bottom plate 1, and the extension plate 14 is attached to the cardboard box side wall 3 after the packaging box is assembled.

[0046] In this embodiment, through the setting of the extension plate 14, when the cardboard box side wall 3 is installed at the upper edge of the cardboard box bottom plate 1, the bottom corners of the cardboard box side wall 3 are protected through the setting of the extension plate 14, so as to improve the strength of the cardboard box side wall 3 and avoid problems such as the cardboard box side wall 3 turning up, so as to achieve the effect of protecting the cardboard box side wall 3 and improving its stability.

[0048] In this embodiment, through the setting of the connection jack 51, the prefabricated corrugated board 5 is installed at the top end of the fixed insert 13 to achieve the effect of fixing the prefabricated corrugated board 5. Furthermore, by setting the prefabricated corrugated boards 5 in different shapes, the packaging box can fix objects of different shapes, including but not limited to spheres, cylinders, and cube items, as Figure 7 and Figure 8 shown, only the fixing of cylindrical items and cube items is demonstrated here.

[0049] In a further preferred embodiment of the present utility model, as Figure 1 - 8As shown, the bottom plate 1 of the carton, the upper cover 2 of the carton, and the support member 4 are all made of plastic, and grooves 15 are provided at the centers of the four corners at the bottom end of the bottom plate 1 of the carton.

[0050] In this embodiment, since the bottom plate 1 of the carton, the upper cover 2 of the carton, and the support member 4 are all made of plastic, the bottom, the upper end, and the corners of the side of the packaging box all have high strength. Therefore, when under pressure, the possibility of deformation of the packaging box can be effectively reduced. And because the right-angle folding plate 41 of the support member 4 can effectively protect both sides of the side wall 3 of the carton, and the extension plate 14 and the above-mentioned support bars can support the upper and lower ends of the side wall 3 of the carton, thereby effectively reducing the possibility of damage to the side wall 3 of the carton, and further effectively improving the safety of the packaging box.

[0051] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
