Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a one-piece folding packaging box. Background Technology

[0002] In the field of product packaging, traditional packaging boxes have always been the mainstream choice. They come in various structural forms, but most are fixed-size hexagonal boxes. These boxes are usually made of materials such as cardboard and plastic, and are formed and fixed by adhesive, connecting nails, or complex tongue and groove structures. Taking common electronic product packaging boxes as an example, they are generally made of cardboard, and the inside is filled with plastic foam and other fillers to fix the product and ensure the safety of the product during transportation and storage. Food packaging boxes mostly use a paper top and bottom lid structure, combined with plastic film sealing to maintain the freshness of food.

[0003] Traditional packaging boxes are mostly closed structures, preventing users from directly observing the contents. For example, finding a specific item often requires frequent opening of the box, increasing inconvenience and causing wear and deformation due to repeated opening and closing, thus shortening the box's lifespan. Take small office supply boxes as an example: users may need to repeatedly open multiple boxes to find a specific stationery item, increasing the risk of damage. Traditional packaging boxes are usually fixed in size, making it difficult to adjust them flexibly according to the actual dimensions of the items. This results in either wasted space or items not fitting properly inside the box when loading items of different sizes. For instance, when transporting irregularly shaped handicrafts, traditional boxes may not fit perfectly, causing the items to shift during transport and increasing the risk of damage. Conversely, when loading smaller items, traditional boxes often have a lot of empty space, reducing space utilization. Furthermore, many traditional packaging boxes have complex locking and unlocking mechanisms, requiring manual operation or tools. For example, some packaging boxes with snap-fit ​​structures require users to press or pry the snaps forcefully when opening and closing them, which is quite strenuous and can easily damage the snaps. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a one-piece folding packaging box to solve the problems of low visibility, poor space adaptability, and inconvenient locking and releasing operation of traditional packaging boxes.

[0005] To achieve the above objectives, this utility model provides a one-piece folding packaging box, comprising: a first side panel; second side panels on both sides of the short side of the first side panel; a rear side panel on one side of the long side of the first side panel; a front side panel on the other side of the long side of the first side panel; a top panel on the other side of the long side of the rear side panel; a top panel on the side of the front side panel away from the first side panel; a handle hinged to one side of the second side panel; several through holes on the handle; several thin ropes wound in the through holes for fixing the two second side panels; and a fixing assembly on the top panel for assembling and fixing the two top panels.

[0006] Preferably, a transparent plate is installed on the front side panel, and expansion joints are provided on the rear side panel, the second side panel, and the front side panel.

[0007] Preferably, the fixing assembly includes a first mounting seat fixedly installed on one side of one of the top plates, a locking rod slidably installed in the first mounting seat, and a second mounting seat fixedly installed on one side of the other top plate, the second mounting seat having a sliding hole, the locking rod being adapted to the sliding hole.

[0008] Preferably, the first mounting base has a sliding groove, and a plurality of sliding plates are slidably installed in the sliding groove. The sliding plates are fixedly installed in the middle of the locking rod. Return springs are fixedly installed on both sides of the sliding plates. The other side of the return springs is fixedly installed on one side of the sliding groove. The first mounting base has a sliding hole, and the locking rod is slidably installed in the sliding hole.

[0009] Preferably, the sliding groove and the sliding hole penetrate each other.

[0010] Preferably, the second mounting base has a receiving cavity that is adapted to the first mounting base, and the sliding hole has the same diameter as the sliding hole.

[0011] Preferably, a plurality of anti-slip blocks are fixedly installed inside the handle, and the anti-slip blocks are made of elastic rubber.

[0012] Preferably, a slide rod is slidably installed in the slide hole, and the slide rod abuts against the locking rod.

[0013] The beneficial effects of this utility model are:

[0014] 1. This one-piece folding packaging box, with its transparent panel and telescopic joints, enables visual monitoring of the packaging contents. Users can clearly observe the storage status of the items inside without opening the box. This feature significantly improves ease of use and reduces packaging damage caused by frequent opening and closing. Simultaneously, the telescopic joint structure on the rear, second, and front panels, with its unique stretchable and compressible characteristics, allows the side wall length of the packaging box to be flexibly adjusted according to actual needs. This dynamic volume adjustment mechanism not only greatly expands the applicability of the packaging box, enabling it to adapt to the loading requirements of items of different sizes, but also achieves a dual breakthrough in both space utilization and functionality.

[0015] 2. This one-piece folding packaging box, through the setting of a fixing component, realizes the quick locking and releasing function of the packaging box. The cooperation between the locking rod and the sliding hole ensures the rigid connection when the top plate is closed. The automatic rebound mechanism driven by the return spring allows unlocking and relocking to be completed with one hand. The cooperation between the sliding groove and the sliding plate maintains the movement trajectory of the locking rod. This component keeps the packaging box compact and flat in the folded state, and the structure is stable and reliable when unfolded, which greatly improves the convenience of use and structural durability, while optimizing storage efficiency.

[0026] like Figures 1 to 5 As shown, a one-piece folding packaging box includes: a first side panel 1; second side panels 3 are provided on both sides of the short side of the first side panel 1; a rear side panel 2 is provided on one side of the long side of the first side panel 1; a front side panel 4 is provided on the other side of the long side of the first side panel 1; a top panel 5 is provided on the other side of the long side of the rear side panel 2; a top panel 5 is also provided on the side of the front side panel 4 away from the first side panel 1; a handle 7 is hinged to one side of the second side panel 3; several through holes 8 are provided on the handle 7; several thin ropes are wound in the through holes 8 to fix the two second side panels 3; a fixing component is provided on the top panel 5 to assemble and fix the two top panels 5; a transparent panel 6 is installed on the front side panel 4; and telescopic joints 19 are provided on the rear side panel 2, the second side panel 3, and the front side panel 4.

[0027] When in use, the first side panel 1 serves as the main supporting structure. The second side panels 3 on both sides of its short side, together with the rear side panel 2 on one side of the long side and the front side panel 4 on the other side, form the side wall frame of the packaging box. The top panels 5 extending from the rear side panel 2 and the front side panel 4 are locked together by fixing components to form a stable top closed structure, ensuring the load-bearing capacity and sealing of the packaging box. The handle 7 is connected to the second side panel 3 by a hinge. The thin rope inserted in the through hole 8 can tighten and fix the second side panels 3 on both sides when tying, while also providing a convenient lifting function. The transparent panel 6 of the front side panel 4 is set to make it easy to see the status of the items inside the box. The telescopic joints 19 set on the rear side panel 2, the second side panel 3 and the front side panel 4 can change the length of the side panels by stretching or compressing, thereby dynamically adjusting the internal volume of the packaging box to adapt to the loading needs of items of different sizes. The overall structure achieves compact storage and quick unfolding through a dual adjustment mechanism of folding and telescopic, taking into account both transportation efficiency and usage flexibility.

[0028] like Figure 3 , Figure 4 , Figure 5 As shown, the fixing assembly includes a first mounting base 9 fixedly installed on one side of one of the top plates 5, with a locking rod 15 slidably installed in the first mounting base 9; a second mounting base 11 fixedly installed on one side of the other top plate 5, with a sliding hole 14 formed in the second mounting base 11, the locking rod 15 being adapted to the sliding hole 14; a sliding groove 18 formed in the first mounting base 9, with several sliding plates 17 slidably installed in the sliding groove 18, the sliding plates 17 being fixedly installed in the middle of the locking rod 15, and return springs 16 fixedly installed on both sides of the sliding plates 17. The other side of the spring 16 is fixedly installed on one side of the sliding groove 18. A sliding hole 10 is provided in the first mounting base 9, and the locking rod 15 is slidably installed in the sliding hole 10. The sliding groove 18 and the sliding hole 10 are connected. A receiving cavity 12 is provided in the second mounting base 11, and the receiving cavity 12 is adapted to the first mounting base 9. The sliding hole 14 has the same diameter as the sliding hole 10. Several anti-slip blocks 20 are fixedly installed in the handle 7, and the anti-slip blocks 20 are made of elastic rubber. A sliding rod 13 is slidably installed in the sliding hole 14, and the sliding rod 13 abuts against the locking rod 15.

[0029] The top plates 5 extending from the rear side plate 2 and the front side plate 4 are locked together by a fixing assembly to form a stable top closed structure. Specifically, the first mounting base 9 provides axial sliding guidance for the locking rod 15 through the sliding hole 10. The middle part of the locking rod 15 is laterally limited by the sliding plate 17 and the sliding groove 18. The return springs 16 on both sides of the sliding plate 17 normally push the locking rod 15 to keep it extended, ensuring that the locking rod 15 is stably engaged with the sliding hole 14 of the second mounting base 11. When unlocking is required, an external force is applied to the sliding rod 13 to make it slide along the sliding hole 14 and press against the locking rod 15. After being pressed, the locking rod 15 drives the sliding plate. 17. The compression return spring 16 is displaced towards the inside of the sliding groove 18 until the locking rod 15 is completely disengaged from the sliding hole 14 to achieve separation. After the external force is removed, the return spring 16 pushes the slide plate 17 to reset, and the locking rod 15 automatically springs back to the initial locking position. The receiving cavity 12 of the second mounting base 11 provides alignment space for the first mounting base 9. The equal diameter setting of the sliding hole 14 and the sliding hole 10 ensures the straightness of the movement trajectory of the locking rod 15. The anti-slip block 20 enhances the grip stability of the handle 7 through elastic friction. This component achieves one-way operation and two-way locking through mechanical linkage and elastic reset, combining structural strength and ease of operation.
