Description

Technical Field

[0001] This utility model relates to the field of folding case technology, specifically to a folding case that can be opened from the inside out. Background Technology

[0002] Reusable containers are designed and manufactured to facilitate the efficient turnover of goods in production, distribution, and consumption. They typically have a certain strength, rigidity, and regular shape, enabling them to safely and stably support goods and facilitate handling, stacking, loading, and unloading operations.

[0003] For example, the patented patent CN211494909U discloses a turnover box panel and a turnover box, including a first box panel and a second box panel. The second box panel is heat-fused to the first box panel. Both the first and second box panels are provided with circumferentially distributed circumferential bosses and heat-fused bosses. The circumferential bosses surround the heat-fused bosses, and the height of the heat-fused bosses is higher than the height of the circumferential bosses. A receiving groove is formed between the circumferential bosses and the heat-fused bosses. The turnover box in this patent is a non-foldable, fixed structure that cannot be opened from the inside or outside. This design limits its flexibility of use, for example, when empty boxes are returned or stored idle. When stored, the space occupied by the non-foldable container is basically the same as when loaded. This results in a large amount of space being ineffectively occupied during the return trip of logistics transportation or warehouse storage. Because it cannot be folded, transport vehicles cannot carry more empty containers, increasing the number of transport trips and costs. In warehouses, idle non-foldable containers occupy a large amount of valuable storage space, reducing warehouse utilization. At the same time, during loading and unloading, operators can only operate from the fixed opening of the container. When the goods are large in size or have special shapes, the difficulty of loading and unloading increases, and there may even be situations where the goods cannot be loaded or unloaded smoothly.

[0004] Therefore, it is necessary to invent a folding box that can be opened from the inside out to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a foldable box that can be opened from both inside and outside, which solves the problem that the fixed structure of the turnover box, which cannot be folded and cannot be opened from both inside and outside, limits its flexibility of use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a folding box that can be opened from the inside out, comprising a mesh-reinforced base, a side plate one hinged to the left side of the mesh-reinforced base, a side plate two hinged to the right side, a front plate hinged to the front end of the mesh-reinforced base, and a rear plate hinged to the rear end. A pre-positioning structure and an unlockable locking structure are provided at the connection points between the front plate, the rear plate, and the side plates one and two. The pre-positioning structure includes mutually cooperating T-shaped inserts and T-shaped slots. The T-shaped inserts are located at the left and right ends of the rear plate and the front plate, and the T-shaped slots are opened on the inner sidewalls of the side plates one and two. The locking structure is a switch latch assembly. By releasing the lock of the switch latch assembly, the side plates one, two, the front plate, and the rear plate can be folded inwards or outwards onto the mesh-reinforced base.

[0007] Preferably, the four corners of the mesh-reinforced base adopt a double-layer impact-resistant structure, and the corners are rounded.

[0008] Preferably, the outer surfaces of side panel one and side panel two have reserved flat areas for printing logos and related information.

[0009] Preferably, both side plate one and side plate two are provided with hollow handles for gripping, and the gripping area of ​​the hollow handles adopts an arc transition design.

[0010] Preferably, the switch latch assembly includes a latch head, a latch connecting arm, and a latch body, wherein the latch head is connected to the latch connecting arm via a connecting protrusion.

[0011] Preferably, the buckle connecting arm is provided with an elastic deformation claw, the side walls of the first side plate and the second side plate are provided with a buckle groove adapted to the buckle body, and the rear wall of the rear plate and the front wall of the front plate are provided with a groove adapted to the buckle head.

[0012] Preferably, the external dimensions of the folding box are L600mm×W400mm×H350mm, and the internal dimensions are L565mm×W365mm×H340mm.

[0013] Preferably, the suitable operating temperature of the folding box is -20℃ to +60℃, and the single box load capacity is ≤40kg.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This utility model effectively solves the problem of insufficient flexibility in the use of traditional turnover boxes caused by their fixed and non-foldable design by using a hinged structure of a grid-reinforced base, side panels, and front and rear panels, combined with a pre-positioning structure and an unlockable locking structure. Specifically, the pre-positioning cooperation of the T-shaped insert and the T-shaped slot can quickly achieve the initial docking of the side panels and the front and rear panels when the folding box is unfolded, while the switch buckle assembly firmly fixes each panel with the locking force of the elastic deformation claw, ensuring the structural stability under load. When folding is required, simply release the lock of the switch buckle assembly to allow the first side panel, the second side panel, the front panel, and the rear panel to fold inward or outward onto the grid-reinforced base, greatly reducing the storage space, facilitating the transportation and storage of empty boxes, and reducing logistics costs.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1-8The folding case shown includes a mesh-reinforced base 1. A side panel 2 is hinged to the left side of the mesh-reinforced base 1, and a side panel 3 is hinged to the right side. A front panel 6 is hinged to the front end of the mesh-reinforced base 1, and a rear panel 5 is hinged to the rear end. The connection between the front panel 6, the rear panel 5 and the side panels 2 and 3 is provided with a pre-positioning structure and an unlockable locking structure. The pre-positioning structure includes a T-shaped insert 7 and a T-shaped slot 8 that cooperate with each other. The T-shaped insert 7 is located at the left and right ends of the rear panel 5 and the front panel 6. The T-shaped slot 8 is opened on the inner side wall of the side panels 2 and 3. The locking structure is a switch latch assembly 9. By releasing the lock of the switch latch assembly 9, the side panels 2, 3, front panel 6, and rear panel 5 can be folded inward or outward onto the mesh-reinforced base 1.

[0019] In this embodiment, the hinged structure allows for flexible connection between side panel 2, side panel 3, front panel 6, rear panel 5, and the mesh-reinforced base 1, enabling quick and easy erection or lowering of each panel. The T-shaped insert 7 and T-shaped slot 8 in the pre-positioning structure provide initial positioning for the connection between the panels, making the assembly process more precise and efficient, reducing assembly time and difficulty. The switch and latch assembly 9 enables quick locking and unlocking between panels, further simplifying the assembly and disassembly of the turnover box and improving work efficiency.

[0020] The four corners of the mesh-reinforced base 1 adopt a double-layer impact-resistant structure, and the corners are rounded. The outer surfaces of side plate 1 2 and side plate 2 3 have reserved flat areas for printing logos and related information. Both side plate 1 2 and side plate 2 3 have hollow handles 4 for gripping. The gripping area of ​​the hollow handles 4 adopts an arc transition design.

[0021] In this embodiment, the double-layer anti-impact structure at the four corners of the grid-reinforced base 1 can effectively resist external impact forces. During logistics transportation and handling, the turnover box may be subjected to external forces such as collisions and squeezing. The double-layer structure can disperse and absorb these impact forces, protecting the goods inside the box from damage. The rounded corner design not only makes the turnover box more aesthetically pleasing, but also reduces damage to other objects and the turnover box itself during collisions, extending the service life of the turnover box. At the same time, printing a logo can enhance the brand recognition of the enterprise and play a role in publicity and promotion during the logistics process.

[0022] The switch latch assembly 9 includes a latch head 901, a latch connecting arm 902, and a latch body 905. The latch head 901 is connected to the latch connecting arm 902 via a connecting protrusion 903. The latch connecting arm 902 is provided with an elastic deformation claw 904. The side walls of the first side plate 2 and the second side plate 3 are provided with latch grooves 906 that are adapted to the latch body 905. The rear wall of the rear plate 5 and the front wall of the front plate 6 are provided with grooves that are adapted to the latch head 901.

[0023] In this embodiment, the elastic deformation claw 904 provided on the buckle connecting arm 902 gives the switch buckle assembly 9 a certain elastic deformation capability. When assembling and disassembling the turnover box, the elastic deformation claw 904 can deform accordingly according to the magnitude and direction of the external force, so that the buckle head 901 can smoothly enter or exit the groove, and the buckle body 905 can easily embed or leave the buckle slot 906. This not only simplifies the assembly and disassembly operation of the turnover box, but also improves work efficiency.

[0024] The external dimensions of the folding case are L600mm×W400mm×H350mm, and the internal dimensions are L565mm×W365mm×H340mm. The suitable operating temperature for the folding case is -20℃ to +60℃, and the load capacity of a single folding case is ≤40kg.

[0025] In this embodiment, the external dimensions of these folding boxes are L600mm×W400mm×H350mm. During warehouse storage and loading into transport vehicles, staff plan the space reasonably according to these dimensions. The internal dimensions are L565mm×W365mm×H340mm, and the folded height is 83mm. Staff arrange the product placement according to the internal dimensions to ensure that the products can be placed stably and safely inside the box. In this region, winter temperatures can sometimes drop to around -15℃, while summer temperatures can reach around 55℃. The suitable operating temperature of the folding boxes is -20℃ to +60℃, which is fully adaptable to the local climate conditions. During delivery, the folding boxes can be used normally whether it is a cold morning or a hot afternoon. When loading, staff strictly follow the standard of single box load capacity ≤40kg to ensure that the weight of goods in each box does not exceed 40kg.

[0026] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-8When using this utility model, firstly, the operator needs to unlock the switch latch assembly 9. Since the latch connecting arm 902 is equipped with an elastic deformation claw 904, applying appropriate external force by pressing the latch head 901 inward with the thumb and forefinger will cause the elastic deformation claw 904 to deform elastically under the force, causing the latch body 905 to disengage from the slots 906 opened on the side walls of side plate 1 2 and side plate 2 3. This releases the locking state of the switch latch assembly 9 on side plate 1 2, side plate 2 3, front plate 6, and rear plate 5. After unlocking, the operator can begin to fold the front plate 6 and rear plate 5, because the front... The front panel 6 and the rear panel 5 are hinged to the front and rear ends of the mesh-reinforced base 1, respectively. Therefore, the front panel 6 can be folded forward and the rear panel 5 can be folded backward with the hinge as the axis, so that the front panel 6 and the rear panel 5 move closer to the mesh-reinforced base 1. Then, the side panels 1 and 2 can be folded. Since the side panels 1 and 2 can be hinged to the left and right sides of the mesh-reinforced base 1, respectively, the side panels 1 can be folded to the left and the side panels 2 can be folded to the right with the hinge as the axis (they can also be folded inward or outward according to the actual space and operating habits). This is to realize the folding of the turnover box, which is convenient for subsequent transportation and storage.
