[0031] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0034] See also Figure 1 and Figure 5 The utility model discloses a suspended fastening packaging box, which includes a box body 1, wherein the box body 1 has a receiving cavity, the receiving cavity is used to place a product, and a limiting assembly 2 is provided in the receiving cavity, and the limiting assembly 2 is used to limit the product when the product is placed in the receiving cavity; specifically, the limiting assembly 2 includes at least two limiting plates, and the at least two limiting plates are arranged oppositely and surrounded to form a limiting groove. The limiting plates can rotate relative to the box body 1, and the two limiting plates arranged oppositely are used to approach or move away from each other during the rotation process, so that the size of the limiting groove can be adjusted.

[0035] Based on this structure, when using the packaging box of the utility model, the limiting plates can be adjusted first so that the two relatively set limiting plates are moved away from each other to form a limiting groove of maximum size; then the product can be placed in the limiting groove, and then the two relatively set limiting plates can be moved closer to each other to clamp the product.

[0036] The limiting plate can be connected to the bottom wall of the box body 1 through a fold, and the limiting plate can be rotated through the fold; specifically, when the two limiting plates rotate close to each other, the size of the limiting groove becomes smaller; when the two limiting plates rotate away from each other, the size of the limiting groove becomes larger. When the product is placed in the limiting groove, the gravity of the product acts on the limiting plate, and the limiting plate supports the product obliquely upward, and the bottom wall of the box body 1 provides support force for the limiting plate, so that the two limiting plates arranged opposite to each other can clamp the product.

[0037] In this way, at least two limiting plates can limit the product from the side of the product to ensure that the product does not swing forward and backward or left and right during transportation. In addition, the limiting plates can hold the product in the air to prevent the product from directly contacting the inner wall of the box 1, thereby reducing the impact force on the product during transportation.

[0038] Furthermore, the limiting assembly 2 includes a support plate 22, on which at least two limiting plates are disposed, and at least two limiting plates are disposed opposite to each other. Figure 2 The limiting plate includes a clamping plate segment 21 and a rotating plate segment 23; wherein the rotating plate segment 23 is connected to the supporting plate 22 by a fold, the rotating plate segment 23 can rotate relative to the supporting plate 22 through the fold, and the rotating plate segment 23 is used to drive the clamping plate segment 21 to rotate in the opposite direction during the rotation process. At the same time, the clamping plate segment 21 is used to approach or move away from the supporting plate 22 during the rotation process.

[0039] Based on this structure, when using, refer to Figure 3 , place the limit assembly 2 in the box 1, adjust the clamping plate segment 21 of the limit plate to rotate upward away from the mounting plate, so that the size of the limit slot becomes larger; at the same time, the rotating plate segment 23 rotates downward relative to the support plate 22 to the bottom of the support plate 22 under the drive of the clamping plate segment 21. Then place the product in the limit slot, the support plate 22 is depressed downward under the gravity of the product, and at the same time, the rotating plate segment 23 rotates upward relative to the support plate 22 to the side of the support plate 22 under the pressure of the product, and the clamping plate segment 21 rotates downward and approaches the product under the drive of the rotating plate segment 23, thereby automatically clamping the product.

[0040] When the rotating plate segment 23 rotates upward relative to the supporting plate 22 to the side of the supporting plate 22, the rotating plate segment 23 is pressed against the side wall of the box body 1, thereby supporting the clamping plate segment 21 to clamp the product. In addition, when the rotating plate segment 23 is pressed against the side wall of the box body 1 at an angle, there is still a buffer gap between the bottom of the supporting plate 22 and the bottom of the box body 1, thereby absorbing external forces and preventing external collisions from directly acting on the product.

[0041] In this way, the product can be pressed downward under its own gravity, while driving the two relatively arranged limit plates to approach each other until they abut against the sides of the product, thereby automatically clamping the product in the limit groove.

[0042] In addition, when the limiting component 2 is arranged at the bottom of the box body 1, a soft cushion or an air cushion can be arranged at the bottom of the support plate 22, which is bonded to the bottom of the support plate 22 through an adhesive layer and can absorb external forces.

[0043] During the handling or transportation process, if the packaging box falls or is hit, the soft cushion and the air cushion can be squeezed by the bottom wall of the box body 1, thereby absorbing the external force and preventing the product from colliding with the inner wall of the box body 1 and being damaged. In addition, the soft cushion or the air cushion separates the support plate 22 in the middle of the limiting assembly 2 from the bottom wall of the box body 1, allowing the product to be pressed down within a certain range, and preventing the product from colliding with the box body 1 during the pressing process.

[0044] Furthermore, four limit plates may be arranged on the support plate 22 , and the four limit plates are arranged opposite to each other in pairs in two directions perpendicular to each other.

[0045] On the basis of this structure, when in use, the clamping plate segments 21 of each limiting plate can be rotated away from the supporting plate 22 to adjust the size of the limiting groove to become larger; then the product can be placed in the limiting groove, and the gravity of the product drives the supporting plate 22 to press down, and when the supporting plate 22 is pressed down, it drives the rotating plate segment 23 to rotate upward, and at the same time, the rotating plate segment 23 drives the clamping plate segment 21 to rotate downward and close to the product, so that the size of the limiting groove becomes smaller and adapts to the size of the product; then the four limiting plates clamp the product.

[0046] In this way, four limit plates can surround and clamp the product from all sides to ensure that the product does not shake laterally. At the same time, multiple limit plates can evenly distribute the weight of the product to ensure the suspended support effect of the product.

[0047] Furthermore, the limiting plate has a limiting surface, and the limiting surface is an arc-shaped surface.

[0048] It should be noted that the limiting surface is the surface that fits and squeezes the product when the limiting plate clamps the product. When the limiting surface is an arc surface, the limiting groove is suitable for accommodating cylindrical products; in this case, at least two limiting plates can be provided, and at least two arc-shaped limiting plates enclose each other to form a circular limiting groove. Since the arc surface can fit with the arc-shaped side of the cylindrical product over a larger area, it can clamp the product better than a flat surface.

[0049] Furthermore, a first connecting plate 24 is provided on a limiting plate, and one end of the first connecting plate 24 is connected to the rotating plate section 23 via a fold, and the other end of the first connecting plate 24 is connected to the box body 1 via a fold, so that the limiting assembly 2 can rotate relative to the box body 1, and the limiting assembly 2 is used to enter or exit the box body 1 during the rotation process.

[0050] Based on this structure, when in use, the first connecting plate 24 is rotated relative to the box body 1 into the box body 1 to bring the limiting assembly 2 into the box body 1; then the first connecting plate 24 is adjusted to fit the inner wall of the box body 1, so that the limiting assembly 2 is laid on the bottom of the box body 1.

[0051] Thus, by forming the limiting component 2 and the box body 1 into one piece, the waste of materials can be effectively reduced; Figure 4 When the packaging box is in an unfolded state, the limiting component 2 can also be laid flat to save space and facilitate the transportation of the packaging box.

[0052] Further, the box body 1 includes a box body 11 and a box cover 12. Specifically, the limiting assembly 2 is arranged at the bottom of the box body 11, and a fastening assembly is arranged on the box cover 12. The box cover 12 can move closer to or away from the box body 11, and the fastening assembly is used to press the limiting groove when the box cover 12 is close to the box body 11.

[0053] More specifically, the fastening assembly includes a pressure plate 13 and an elastic member, wherein a through groove is provided in the middle of the pressure plate 13, and the elastic member is arranged in the through groove, and the elastic member is used to be deformed by force when the pressure plate 13 is pressed toward the limiting groove, thereby shrinking inward to generate a fastening force.

[0054] Based on this structure, during assembly, the limiting assembly 2 can be placed into the bottom of the box body 11, and then the product can be placed into the limiting groove. The support plate 22 is pressed down by the gravity of the product, and drives the limiting plate to clamp the product inward, so that the side of the product is limited. Then, the box cover 12 is moved toward the box body 11 and covers the opening of the box body 11. When the box cover 12 is close to the box body 11, the fastening assembly presses the limiting groove downward, thereby pressing the product into the box body 1, so that the top of the product is limited.

[0055] Since the limiting plate clamps the product from the side, the top of the product protrudes from the limiting groove. When the pressure plate 13 of the fastening assembly presses the limiting groove downward, the elastic part in the middle of the pressure plate 13 is pressed on the top of the product, and is squeezed and deformed with the product when the box cover 12 is pressed down, thereby shrinking inward to generate a fastening force, and the top of the product is wrapped in the elastic part.

[0056] In this way, the side of the product is limited by the limiting assembly 2, and the bottom of the product is suspended by being clamped by the limiting block, and the top of the product is fastened by being wrapped by an elastic member. The product is fixed in all directions and is not easy to collide with the box wall.

[0057] Furthermore, an elastic connecting section 16 is provided on the side of the pressing plate 13 facing away from the box body 11 , and the elastic connecting section 16 is connected to the inner side of the box cover 12 ; wherein a buffer interval is formed between the pressing plate 13 and the box cover 12 by the elastic connecting section 16 .

[0058] Among them, the elastic connecting section 16 can be an air cushion, a cotton pad or a rubber plate; when the outside of the box cover 12 is impacted, the air cushion, cotton pad or rubber plate between the pressure plate 13 and the box cover 12 can be compressed and deformed, thereby absorbing the external load.

[0059] Furthermore, the elastic connecting section 16 can also be a second connecting plate, which is made of cardboard, and the two ends of the second connecting plate are respectively connected to the box cover 12 and the pressing plate 13. In this way, the second connecting plate plays the role of connecting the fastening assembly to the box cover 12; at the same time, the second connecting plate separates the pressing plate 13 from the box cover 12 and forms a buffer interval, which can provide deformation space for the elastic member on the pressing plate 13. After the elastic member wraps the top of the product, the top of the product and the box cover 12 are suspended due to the buffer interval, thereby preventing the product from colliding with the inner wall of the box body 1.

[0060] Furthermore, the elastic member is a TPU plastic film 15, and the periphery of the TPU plastic film 15 is bonded to the pressing plate 13 via an adhesive layer; wherein the TPU plastic film 15 is used to protrude toward the buffering interval when squeezed by an external force.

[0061] On the basis of this structure, when the fastening assembly is in use, the box cover 12 is first pressed against the box body 11, and the pressing plate 13 is pressed against the limiting groove, and at the same time, the TPU plastic film 15 in the middle of the pressing plate 13 is pressed against the top of the product; under the pressing action of the box cover 12, the TPU plastic film 15 is squeezed against the product and deformed, and the TPU plastic film 15 protrudes toward the buffer interval and shrinks inward to generate a fastening force, thereby wrapping the top of the product.

[0062] In this way, the product is fastened by utilizing the property that the TPU plastic film 15 deforms and tightens when stretched under force, and the product is suspended in the air, which can better protect the product.

[0063] In some other embodiments, the elastic member may include a telescopic net 14 and a TPU plastic film 15, and the telescopic net 14 is wrapped around the periphery of the TPU plastic film 15, and the periphery of the telescopic net 14 is fixedly connected to the pressing plate 13. The telescopic net 14 is used to stretch when the pressing plate 13 is pressed toward the limiting groove, so that the TPU plastic film 15 protrudes toward the buffer interval.

[0064] Based on this structure, the stretchability of the telescopic net 14 is better than the stretchability of the TPU plastic film 15 under stress and deformation. Therefore, by arranging the telescopic net 14 on the periphery of the TPU plastic film 15, when the pressure plate 13 is pressed against the limiting groove, the product pushes the TPU plastic film 15 upward, and the TPU plastic film 15 drives the telescopic net 14 to stretch and protrude toward the buffer interval, and the TPU plastic film 15 shrinks and wraps the product.

[0065] In this way, by adopting the telescopic net 14 with better stretchability, the squeezing force of the product on the elastic member can be reduced, and the wrapping of the elastic member on the product can be enhanced; at the same time, the setting area of ​​the TPU plastic film 15 becomes smaller, which can save costs.

[0066] In addition, the elastic member may also be a cloth belt or a rubber belt with a certain degree of ductility, which can shrink inwards after being stretched to generate a tightening force.

[0067] Furthermore, the box body 11 has an opening, and the box cover 12 is connected to one side of the opening through a fold, wherein the box cover 12 can be rotated toward or away from the opening through the fold, and the box cover 12 is used to drive the fastening assembly to be pressed toward or away from the limiting groove during the rotation process.

[0068] In this way, when the box cover 12 is closing the opening, the fastening assembly presses against the limit groove and fastens the product, so that the fastening and sealing are completed in one step, saving packaging time; when opening the box, the box cover 12 is moved away from the opening, and at the same time the fastening assembly releases the fastening of the product, and the product can be taken out in a vertical direction.

[0069] Furthermore, a receiving groove 25 is provided on the support plate 22 , and the receiving groove 25 is used to receive the clamping plate segment 21 when the clamping plate segment 21 is attached to the support plate 22 .

[0070] Based on this structure, see Figure 4 When the carton is used in an unfolded state, the rotating plate segment 23 can be rotated to be level with the supporting plate 22, and at the same time, the clamping plate segment 21 rotates into the receiving groove 25, so that the limiting component 2 is in a flat state.

[0071] This helps to reduce the space occupied by the limiting plate, facilitates the transportation of the packaging box, and protects the clamping plate section 21 from being pulled.

[0072] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
