Description

Technical Field

[0001] This application relates to the field of packaging, and in particular to a packaging box. Background Technology

[0002] Packaging boxes are boxes used to package goods. They can be classified by material, such as cardboard boxes, tin boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated boxes, PVC boxes, etc. Packaging boxes ensure the safety of goods during transportation and enhance their perceived quality. Among these, cardboard boxes are widely used in the packaging and transportation industry.

[0003] Chinese Patent Publication No. CN205087239U discloses a cardboard box comprising a first side panel, a second side panel, a third side panel, and a fourth side panel connected sequentially, and further comprising a first side panel bottom tongue, a second side panel bottom tongue, a third side panel bottom tongue, and a fourth side panel bottom tongue. The first side panel bottom tongue is rotatably connected to the first side panel, the second side panel bottom tongue to the second side panel, the third side panel bottom tongue to the third side panel, and the fourth side panel bottom tongue to the fourth side panel. The second side panel bottom tongue and the fourth side panel bottom tongue are arranged mirror images of each other on both sides of the third side panel bottom tongue. When the first side panel bottom tongue, the second side panel bottom tongue, the third side panel bottom tongue, and the fourth side panel bottom tongue are bent inwards and assembled, a self-locking bottom assembly method can be achieved.

[0004] Regarding the aforementioned technologies, when cardboard boxes are used to protect internal items, the boxes are prone to deformation due to impact, making it difficult to provide effective protection for the items and causing damage to both the cardboard box and the items inside. Summary of the Invention

[0005] The purpose of this application is to provide a packaging box.

[0006] The packaging box provided in this application adopts the following technical solution:

[0007] A packaging box includes a base plate, side plates respectively disposed on four sides of the base plate, and a top plate. The base plate, the top plate, and the four side plates form a cavity. Each side plate has a connecting plate on two sides adjacent to the base plate. The connecting plates are located within the cavity, and a connecting assembly is provided between adjacent connecting plates. The connecting assembly includes a first clamping plate and a second clamping plate parallel to the side plates. One end of the first clamping plate and the second clamping plate are fixedly connected, and the other end of the first clamping plate and the second clamping plate clamps two adjacent connecting plates.

[0008] By adopting the above technical solution, after the first and second clamps clamp and fix the two adjacent connecting plates, it is difficult for external moisture to enter the cavity through the gaps between the side plates. At the same time, the first and second clamps provide vertical support for the connecting plates and side plates. When subjected to external impact, the side plates remain vertical, thereby reducing the deformation and damage to the packaging box caused by external forces and the destruction of the internal items, and improving the support and protection capabilities of the packaging box.

[0009] Optionally, the base plate has a support frame on one side of the cavity, and the side of the support frame abuts against the side wall of the side plate. The connecting assembly also includes a support rod parallel to the first clamping plate. One end of the support rod is set on the support frame, and the other end is provided with a connecting block. The first clamping plate and the second clamping plate are both fixedly connected to the connecting block, and a reinforcing assembly is provided between adjacent connecting blocks.

[0010] By adopting the above technical solution, the support rod is inserted into the support frame, thereby maintaining the stability of the connection between the support rod and the base plate, thus improving the stability of the first and second clamping plates, thereby further improving the impact resistance of the packaging box. In addition, the reinforcement component connects all the connecting blocks and forms a whole, thereby further improving the support performance of the packaging box, reducing the possibility of the packaging box shaking, and improving the overall stability.

[0011] Optionally, a barrier plate is provided on the side of the side plate away from the bottom plate. The barrier plate includes a first barrier plate, a second barrier plate, and a third barrier plate, which are connected in sequence along the direction away from the bottom plate. The second barrier plate is parallel to the side plate, and the third barrier plate is connected to the support frame. A buffer block is provided between the side plate and the second barrier plate.

[0012] By adopting the above technical solution, the side panel, buffer block, and second barrier plate constitute the triple protection of the packaging box, reducing the possibility of deformation of the packaging box due to external forces. At the same time, the buffer block cushions external impacts and improves the protection of the interior. In addition, due to the triple protection, it is difficult for external moisture to penetrate into the cavity of the packaging box, keeping the inside of the packaging box dry. The first and third barrier plates provide stable support for the buffer block, thereby improving the stability of the buffer block.

[0013] Optionally, the buffer block is square, and the buffer block has several through holes.

[0014] By adopting the above technical solution, the buffer block is set to a square shape, which allows it to make greater contact with the side plate and the second barrier plate, thereby providing better support and cushioning effect. The through holes opened on the buffer block allow it to deform within a certain range. When subjected to external impact, the deformation reduces the impact on the second barrier plate, thereby protecting the items inside the packaging box.

[0015] Optionally, the connecting plate is configured as a first connecting plate, a second connecting plate, and a third connecting plate connected in sequence. The first connecting plate is connected to the side plate, the third connecting plate is bonded to the second barrier plate, the support rod is located between two adjacent first connecting plates, and the first clamping plate and the second clamping plate clamp two adjacent first connecting plates.

[0016] By adopting the above technical solution, the first clamping plate and the second clamping plate first clamp two adjacent first connecting plates, and then the support rod is located between the adjacent first connecting plates. This makes it difficult for external moisture to enter the packaging box because the first clamping plate and the second clamping plate block it. At the same time, the support rod is in the gap between the first connecting plate and the second connecting plate, which further hinders the entry of moisture and improves the waterproof effect. In addition, the third connecting plate and the second barrier plate are bonded and fixed, so that the connecting plate and the barrier plate are firmly inside the packaging box, thereby improving the overall connection stability.

[0017] Optionally, a limiting plate is provided at one end of the connecting block near the cavity, with one side of the limiting plate facing the cavity and the other side of the limiting plate abutting against the side wall of the second connecting plate.

[0018] By adopting the above technical solution, the limiting plate blocks the adjacent first connecting plate from the inside of the cavity, forming a third layer of waterproof and vapor-proof structure. At the same time, the limiting plate supports the second connecting plate, making it difficult for the second and third connecting plates to move, thereby improving the stability of the connecting plates and the barrier plate bonded to the connecting plates.

[0019] Optionally, the reinforcement component includes a first crossbar located between two adjacent connecting blocks. The connecting blocks have a first snap-fit ​​groove with a narrow opening and a wide bottom. The end of the first crossbar is snapped into the snap-fit ​​groove. A corresponding and parallel second crossbar is provided below the first crossbar. The support frame has a second snap-fit ​​groove, and the second crossbar is inserted into the second snap-fit ​​groove and presses the third barrier plate onto the support frame. The buffer block is located between the first crossbar and the second crossbar.

[0020] By adopting the above technical solution, the first crossbar connects all the connecting blocks in sequence, and the second crossbar fixes the third barrier plate on the support frame. Thus, the first crossbar, the second crossbar, the connecting blocks, and the support frame constitute the packaging box skeleton to support the packaging box. At the same time, the buffer block is between the first crossbar and the second crossbar and supports the first crossbar and the second crossbar. When the first crossbar and the second crossbar are impacted, the buffer block can provide cushioning for the first crossbar and the second crossbar, reducing the possibility of damage to the first crossbar and the second crossbar.

[0021] Optionally, the end of the connecting block away from the cavity is provided with a snap-fit ​​block, which abuts against the connection between two adjacent side plates.

[0022] By adopting the above technical solution, the snap-fit ​​block fixes the adjacent side panels from the outside of the packaging box, further improving the stability of the connection between the side panels.

[0023] Optionally, the base plate is provided with a plurality of support blocks located within the support frame, and a support plate is provided at the end of the support block away from the base plate, with the side of the support plate abutting against the inner sidewall of the support frame.

[0024] By adopting the above technical solution, when the packaging box shakes, the support block and support plate support the items inside the packaging box and buffer the impact on the inside and outside of the packaging box, thereby improving the protection effect.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The connecting components serve to fix, support, and protect the packaging box, while also reducing the entry of moisture, thereby improving the packaging box's impact resistance and its ability to protect the contents.

[0027] 2. The reinforcing components create a framework inside the packaging box, further enhancing its support capacity and reducing the possibility of deformation or damage due to external forces.

[0028] 3. Side panels, buffer blocks, and barrier panels provide triple protection for the sides of the packaging box, offering support, protection, and waterproofing. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0038] Example: A packaging box, see reference Figure 1 and Figure 2 It includes a base plate 1, and side plates 2 are fixedly connected to the four sides of the base plate 1. The side plates 2 are set perpendicular to the base plate 1. A top plate 3 is provided on the side of the side plate 2 away from the base plate 1. The top plate 3 is parallel to and opposite to the base plate 1. The top plate 3 covers the side plates 2. The base plate 1, the top plate 3 and the four side plates 2 form a cavity.

[0039] A support frame 4 is fixed to one side of the base plate 1 within the cavity. The support frame 4 is distributed along the side of the base plate 1, and the side wall of the support frame 4 abuts against the inner side wall of the side plate 2. A support assembly is also provided inside the support frame 4. The support assembly includes several support blocks 41 evenly distributed inside the support frame 4. One end of the support block 41 is fixed to the base plate 1, and the other end is fixedly connected to a support plate 42. The support plate 42 is parallel to the base plate 1, and the side wall of the support plate 42 abuts against the inner side wall of the support frame 4.

[0040] Reference Figure 3 and Figure 4 Connecting plates are fixed to the sides of side plate 2 and adjacent sides of side plate 2. The connecting plates include a first connecting plate 21, a second connecting plate 22, and a third connecting plate 23 fixedly connected in sequence. The first connecting plate 21 is fixedly connected to the side of side plate 2 and is bent relative to side plate 2, facing the cavity. The first connecting plates 21 on adjacent side plates 2 abut against each other. The second connecting plate 22 is bent at 90° relative to the first connecting plate 21, and two adjacent second connecting plates 22 are in the same plane.

[0041] Reference Figure 4 and Figure 5A connecting assembly 5 is provided between adjacent first connecting plates 21. The connecting assembly 5 includes a connecting block 51 abutting above the first connecting plate 21. A first clamping plate 52 and a second clamping plate 53 are fixedly connected to the end of the connecting block 51 away from the cavity. The first clamping plate 52 and the second clamping plate 53 are arranged opposite to each other and facing the bottom plate 1. The first clamping plate 52 is located between the first connecting plate 21 and the side plate 2 on the same side, and the second clamping plate 53 is located between the first connecting plate 21 and the side plate 2 on the other side. The first clamping plate 52 and the second clamping plate 53 clamp the two sides of the two adjacent first connecting plates 21, thereby closing the gap between the two adjacent first connecting plates 21 and fixing the adjacent side plates 2 together.

[0042] The connecting block 51 is fixedly connected to the snap-fit ​​block 56. The end of the snap-fit ​​block 56 away from the connecting block 51 is located on the side of the side plate 2 away from the cavity. The side of the snap-fit ​​block 56 close to the cavity is located at the connection of the adjacent side plates 2. The side wall of the snap-fit ​​block 56 abuts against the two adjacent side plates 2 at the same time, thereby further reinforcing the connection between the adjacent side plates 2.

[0043] Reference Figure 3 and Figure 4 A limiting plate 55 is fixedly connected to one end of the connecting block 51 near the cavity. The limiting plate 55 is parallel to the second connecting plate 22. One side of the limiting plate 55 faces the inside of the cavity, and the other side is simultaneously bonded to the side of the two adjacent second connecting plates 22 near the cavity.

[0044] Reference Figure 5 and Figure 6 The connecting assembly 5 also includes a support rod 54 located between two adjacent first connecting plates 21. One end of the support rod 54 is fixedly connected to the middle part of the connecting block 51, and the other end faces and is inserted into the support frame 4. The support frame 4 has a positioning groove 43 opposite to the support rod 54. The end of the support rod 54 away from the connecting block 51 is inserted into the positioning groove 43, and an annular groove 541 is formed on the side wall of the end of the support rod 54 located in the positioning groove 43. An annular block 44 is fixed on the inner wall of the positioning groove 43 and inserted into the annular groove 541.

[0045] Reference Figure 2 and Figure 7To improve the impact resistance of the side panel 2 of the packaging box, a baffle plate is fixedly connected to the side of the side panel 2 away from the bottom plate 1. The baffle plate includes a first baffle plate 24, a second baffle plate 25, and a third baffle plate 26 fixedly connected in sequence. The first baffle plate 24 faces the cavity and is fixedly connected perpendicularly to the side panel 2. The second baffle plate 25 is parallel to the side panel 2, and the side wall of the third connecting plate 23 is bonded and fixed to the side of the second baffle plate 25 away from the side panel 2. The side of the third baffle plate 26 away from the second baffle plate 25 is close to the side panel 2. Thus, a receiving cavity is formed between the baffle plate and the side panel 2. The receiving cavity is filled with a buffer block 7, and the buffer block 7 has a through hole 71 parallel to the side panel 2 to mitigate external impacts.

[0046] In addition, in order to improve the support capacity of the side of the packaging box, a reinforcing component 6 is provided between adjacent connecting blocks 51. The reinforcing component 6 connects two adjacent connecting blocks 51, and at the same time, the reinforcing component 6 fixes the third barrier plate 26 to the support frame 4.

[0047] The reinforcing component 6 includes a first crossbar 61 and a second crossbar 62. The first crossbar 61 is located between two adjacent connecting blocks 51, and also between the first barrier plate 24 and the buffer block 7. A first engaging groove 63 is provided on the connecting block 51, corresponding to the end of the first crossbar 61. The end of the first crossbar 61 is inserted into the first engaging groove 63, and the opening of the first engaging groove 63 is narrow while the bottom is wide, thereby engaging the first crossbar 61.

[0048] The second crossbar 62 is arranged correspondingly and parallel to the first crossbar 61 on the side near the base plate 1. The support frame 4 is also provided with a second locking groove for locking the end of the second crossbar 62. The structure of the second locking groove is the same as that of the first locking groove 63. One side of the second crossbar 62 abuts against the buffer block 7 on the side near the base plate 1, while the other side presses the third barrier plate 26 against the support frame 4.

[0049] The first horizontal bar 61, the second horizontal bar 62, the connecting block 51, and the support frame 4 together form a rectangular box skeleton, thereby supporting and reinforcing the overall packaging box and improving its impact resistance.

[0050] The implementation principle of this application embodiment is as follows: the first clamping plate 52 and the second clamping plate 53 clamp the first connecting plate 21, so that the side plates 2 are fixed to each other. Under the obstruction of the support rod 54 and the limiting plate 55, it is difficult for external moisture to enter the packaging box from the connection between the side plates 2. At the same time, the packaging box skeleton composed of the first crossbar 61, the second crossbar 62, the connecting block 51 and the support frame 4 improves the support capacity of the packaging box. In addition, the side plates 2, the buffer block 7 and the second barrier plate 25 provide triple protection to reduce the damage to the inside of the packaging box caused by external impact. At the same time, due to the support of the buffer block 7, the packaging box is not easily deformed and can play a certain waterproof role.

[0051] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
