Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box technology, and in particular to a corrugated cardboard box that can be spliced ​​together. Background Technology

[0002] Corrugated cardboard boxes are common packaging containers in daily life, widely used in storage, organization, packaging, and transportation. They are usually made of corrugated paper and have good compression resistance and environmental performance. However, in actual use, especially when handling or placing multiple boxes, they are often stacked.

[0003] However, because the two cardboard boxes cannot be effectively locked together or spliced, this stacking method has poor stability and is prone to causing the cardboard boxes to collapse, resulting in damage to goods or personal injury.

[0004] Based on this, in order to facilitate the assembly of stacked cardboard boxes, we propose a type of corrugated cardboard box that can be spliced ​​together. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of existing technologies, such as the inability to effectively interlock or splice the upper and lower cardboard boxes, resulting in poor stability, and to propose a splicable corrugated cardboard box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a modular corrugated cardboard box, including a box body, with connectors and supports respectively provided at the top four corners and bottom four corners of the box body;

[0008] At least a portion of the support extends to the lower side of the housing, wherein the bottom of the support has a pair of mating portions and the top of the connector has a pair of mating grooves, the mating portions and the mating grooves being inserted into each other.

[0009] Both the connector and the support are connected to the housing via fasteners.

[0010] Furthermore, the connector includes a first folded surface and a second folded surface;

[0011] A plurality of first stress-reducing holes are provided between the first fold and the second fold, and the fastener is provided with at least one on both the first fold and the second fold.

[0012] Furthermore, the support member includes two vertically arranged vertical surfaces;

[0013] One of the vertical surfaces has a deformation cut along its length, and the deformation cut forms a third fold on the upper side of the vertical surface. A plurality of second stress-reducing holes are formed between the third fold and the other vertical surface. The fastener is provided with at least one on the third fold and on the vertical surface opposite to it.

[0014] Furthermore, the fastening member includes a columnar portion and a frustum-shaped portion formed on the columnar portion;

[0015] A deformation groove is provided on the end face of the truncated cone portion, extending through the columnar portion. The deformation groove enables two claws to be formed on both sides of the truncated cone portion. Holes that are adapted to the columnar portion are provided on both sides of the box body.

[0016] Furthermore, it also includes a locking member formed on the support member, and a slot adapted to the locking member is provided on the end face of the connector.

[0017] Furthermore, the locking element includes a plate;

[0018] The plate is formed by opening a U-shaped hole in the support member. A third stress relief hole and a fourth stress relief hole are also opened on the end face of the plate. The plate is bent at the fourth stress relief hole and a clip is bent out through the fourth stress relief hole. The clip is engaged in the clip groove.

[0019] The present invention proposes a modular corrugated cardboard box, which has the following advantages: By using connectors and supports on the upper and lower sides of the box, the boxes can be positioned by means of the connectors and supports when stacked, thereby improving the stability of the stack. Furthermore, the supports are designed with locking fasteners to connect and fix the upper and lower boxes, thereby improving the stability of the stacked boxes. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-4 As an embodiment of this utility model, a splicable corrugated cardboard box is disclosed. Specifically, the corrugated cardboard box includes a box body 1, and connectors 2 and support members 3 are respectively provided at the top four corners and bottom four corners of the box body 1.

[0027] Of course, multiple boxes 1 can be provided. In this embodiment, two boxes 1 are stacked on top of each other as an example. The support 3 at the bottom of the upper box 1 and the connector 2 at the top of the lower box 1 are inserted and matched to form a positioning during the stacking process.

[0028] At least a portion of the support member 3 extends to the lower side of the box 1. In this embodiment, the at least a portion is a part of the support member 3. For example, one-third of the length of the support member 3 can be extended to the bottom of the box 1. The purpose of this design is to make the support member 3 usable as a support foot. Specifically, since the support members 3 at the four corners of the box 1 all extend to the lower side of the box 1, when the box 1 is placed, the support members 3 support the box 1, so that the bottom of the box 1 does not contact the ground, thereby protecting the bottom of the box 1. Of course, after adopting the extension design of the support member 3, the connecting member 2 should be designed to move downward above the box 1 to ensure that when two boxes 1 are stacked, the support member 3 and the connecting member 2 are inserted and fit together.

[0029] The support member 3 has a pair of matching portions 30 at its bottom and the connector 2 has a pair of matching grooves 20 at its top. The matching portions 30 and the matching grooves 20 are inserted into each other. In this preferred embodiment, the matching portions 30 are set as V-shaped portions. Obviously, the matching grooves 20 are adapted to be set as V-shaped grooves. The design of V-shaped portions and V-shaped grooves can ensure a good fit between the matching portions 30 and the matching grooves 20.

[0030] Optionally, in this embodiment, both the connector 2 and the support 3 are connected to the housing 1 via fasteners 4. The fasteners 4 are used to make the connector 2 and the support 3 detachable. This not only improves the ease of assembly, but also allows for the disassembly and reuse of the fasteners 4, greatly enhancing the ease of use.

[0031] In some embodiments, the connector 2 of the present invention includes a first folded surface 21 and a second folded surface 22;

[0032] A plurality of first stress-reducing holes 23 are provided between the first fold surface 21 and the second fold surface 22, and the fastening member 4 is provided with at least one on both the first fold surface 21 and the second fold surface 22.

[0033] In the initial state, the first fold 21 and the second fold 22 are horizontally set. During installation, the fastener 4 on the first fold 21 can be connected to the box body 1, at which time the first fold 21 is fixed. Afterwards, the second fold 22 can be bent to keep it perpendicular to the first fold 21, and then it can be fixed to the outside of the box body 1 by the fastener 4 on the second fold 22.

[0034] It should be noted that the stress-reducing holes in this embodiment are designed to reduce the stress during bending of the sheet metal, thereby improving the ease of bending the sheet metal. The function of each stress-reducing hole is the same in the following embodiments, so they will not be described again.

[0035] Based on the above embodiments, the support member 3 in this embodiment includes two vertically arranged vertical surfaces 31;

[0036] One of the vertical surfaces 31 has a deformation cutout 32 along its length. The deformation cutout 32 forms a third fold 33 on the upper side of the vertical surface 31. A plurality of second stress-reducing holes 34 are formed between the third fold 33 and the other vertical surface 31. The fastener 4 is provided with at least one on the third fold 33 and on the vertical surface 31 opposite to it.

[0037] In the initial state, the third fold surface 33 and its adjacent vertical surface 31 are horizontally arranged. During installation, the two vertical surfaces 31 are first attached to the corner of the box body 1, and the entire support 3 is fixed to the box body 1 by the fastener 4 on one of the vertical surfaces 31. Then, the third fold surface 33 is bent so that it is perpendicular to the adjacent vertical surface 31. Then, the other side of the box body 1 is connected by the fastener 4 on the third fold surface 33. In this way, the entire support 3 can be connected and fixed.

[0038] Optionally, the fastening member 4 in this embodiment includes a columnar portion 41 and a frustum-shaped portion 42 formed on the columnar portion 41. The fastening member 4 in this embodiment can be set as an elastic member, such as rubber, so as to ensure that it has a certain deformability.

[0039] In addition, two fasteners 4 are provided on the first fold surface 21 and the second fold surface 22 respectively, two are provided on a vertical surface 31, and two are also provided on the third fold surface 33;

[0040] The end face of the frustum portion 42 is provided with a deformation groove that extends through the columnar portion 41. The deformation groove enables two claws to be formed on both sides of the frustum portion 42. Holes 11 that are adapted to the columnar portion 41 are provided on both sides of the housing 1.

[0041] In this embodiment, by opening a hole 11 on the side of the housing 1, when installing the support 3 and the connector 2, it is only necessary to pass the cone part 42 on its inner side through the hole 11 until the cone part 42 is locked on the inner side of the housing 1. The operation is simple and convenient. Of course, when disassembling, it is only necessary to press the two claws from the inside of the housing 1 to make them retract, and the entire fastener 4 can be pulled out along the hole 11.

[0042] It should be noted that the hole positions 11 described in this embodiment include round holes and straight holes. The round holes can be used to directly adapt to the insertion of the columnar part 41. However, since the second fold surface 22 and the third fold surface 33 are bent after being fixed, the movement trajectory of the corresponding fastener 4 is an arc. Therefore, in this embodiment, some hole positions 11 are set as straight grooves. This can adapt to the movement trajectory of the fastener 4 on the fold surface after bending, so as to ensure that this part of the fastener 4 can be smoothly inserted into the box 1 until the cone part 42 on it stops on the inner side of the box 1. Of course, the inner diameter of the round hole and the height of the straight groove are smaller than the bottom diameter of the cone part 42.

[0043] In some embodiments, the present invention further includes a locking member 5 formed on the support member 3. The locking member 5 and the support member 3 are integrally formed. Of course, in this embodiment, both the connector 2 and the support member 3 can be made of stainless steel. The end face of the connector 2 is provided with a slot 24 that is adapted to the locking member 5. The locking member 5 is designed to engage with the slot 24, so that the upper box 1 and the lower box 1 can be connected and fixed vertically to improve the connection stability of the stacked boxes 1.

[0044] In an optional embodiment, the locking member 5 of this utility model includes a plate 51;

[0045] The plate 51 is formed by opening a U-shaped hole in the support member 3. A third stress relief hole 52 and a fourth stress relief hole 53 are also opened on the end face of the plate 51. The plate 51 is bent at the fourth stress relief hole 53 and a clip 54 is bent out through the fourth stress relief hole 53. The clip 54 is engaged in the clip groove 24.

[0046] Specifically, after the upper and lower boxes 1 are stacked and aligned, the plate 51 can be bent so that it bends downward at the third stress relief hole 52, and then the plate 51 is bent at the fourth stress relief hole 53 so that its end forms a clip 54. Finally, the clip 54 is snapped into the slot 24 of the connector 2, thus achieving the locking and fastening between the upper and lower boxes 1.

[0047] In summary, this utility model employs connectors 2 and support members 3 on the upper and lower sides of the box 1, respectively. When the upper and lower boxes 1 are stacked, they can be positioned by the connectors 2 and support members 3 to improve the stability of the stacking. Furthermore, since the support member 3 is also designed with a locking member 5, the upper and lower boxes 1 are connected and fixed to each other, thereby improving the stability of the stacked boxes 1.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
