Description

Technical Field

[0001] This invention relates to the field of packaging boxes, and more particularly to a packaging box that can be flexibly combined and used, and its method of use. Background Technology

[0002] As is well known, in the existing packaging technology field, especially for packaging solutions for workpieces with irregular structures or special dimensions, traditional packaging containers generally suffer from poor adaptability, insufficient coverage, and low resource utilization. Currently, the widely used packaging methods mainly include customized foam-lined packaging and integral plastic or paper molded boxes. These packaging structures are usually specially designed for specific workpieces. Although they can meet the protection needs of fixed-shape products to a certain extent, their structure is too rigid and cannot be dynamically adjusted according to the actual contour of the workpiece. This results in poor coverage of complex curved surfaces, multiple protrusions, or asymmetrical structures. During transportation, gaps can easily cause shaking, increasing the risk of product damage.

[0003] In addition, existing packaging methods often require the redesign and manufacture of the entire packaging when dealing with workpieces of different sizes and shapes. This not only increases packaging costs and time, but also causes serious waste of packaging materials. Although some adjustable packaging structures have appeared on the market, their adjustment dimensions are mostly limited to the planar direction, making it difficult to achieve flexible adaptation in three-dimensional space. Moreover, the structure is complex, the assembly efficiency is low, and the actual operation experience is poor. At the same time, traditional packaging cannot be effectively disassembled and reassembled after completing one use cycle, resulting in a low secondary utilization rate of packaging materials. Summary of the Invention

[0004] (a) Purpose of the invention In view of this, the purpose of the present invention is to propose a packaging box that can be flexibly combined and its usage method. The packaging box is designed as a modular standard component, which allows the packaging box to be assembled in three-dimensional space according to the shape of the workpiece being packaged. Therefore, after packaging the workpiece, the coverage of the workpiece is better, and such a packaging box structure design makes it suitable for packaging more workpieces.

[0005] (II) Technical Solution To achieve the above-mentioned technical objectives, the present invention provides a packaging box that can be flexibly combined and used. It is composed of several individual packaging boxes, which are assembled in three-dimensional space to form an internally hollow structure. Each individual packaging box includes two parallel end panels, four pillars located between the two end panels, the pillars being located at the corners of the end panels, and four side panels assembled between adjacent pillars. The end panels and pillars, as well as the pillars and side panels, are detachably assembled, so that when the individual packaging boxes are assembled in three-dimensional space, the side panels between adjacent individual packaging boxes can be removed, making the internal spaces of adjacent individual packaging boxes interconnected.

[0006] As a further description of the above technical solution: the column adopts a regular square prism structure, and each of the four sides of the column is provided with a fastening groove. The fastening groove is opened vertically and extends from the top to the bottom of the column. The two sides of the side panel are provided with assembly strips in the vertical direction. The assembly strips can be inserted into the fastening grooves from top to bottom. Based on this, after the column is installed, it is only necessary to start from the top of two adjacent columns, align the assembly strips on the side panel with the fastening grooves on the two columns, and then insert them into the fastening grooves from top to bottom until the bottom of the side panel contacts the end panel located below, thus completing the assembly between the column and the side panel.

[0007] As a further description of the above technical solution: the cross-section of the fastening groove and the assembly strip is T-shaped. Therefore, after the side panel is installed, the T-shaped assembly strip structure can provide tension to the two columns, increasing the stability of the packaging box assembly.

[0008] As a further description of the above technical solution: the individual packaging boxes are connected by interlocking assembly strips. The cross-section of the assembly strips is "H". When two adjacent individual packaging boxes are spliced ​​together, the interlocking grooves on the contact surfaces of the two contacting pillars in the two adjacent individual packaging boxes are connected to form a closed groove structure with a cross-section of "H". The assembly strips are inserted into the closed groove structure of "H" from top to bottom, so that the two contacting pillars are interlocked. Based on this, the two adjacent pillars do not need to use other similar bolt structures for connection. Only the assembly strips need to be inserted, which is convenient and quick to operate.

[0009] As a further description of the above technical solution: Each end of the column has a stepped groove at its center, and the center of the stepped groove has a threaded hole. The upper and lower columns are detachably connected via a column connector. The column connector includes a shaft with a diameter smaller than the inner diameter of the stepped groove and studs integrally formed at the top and bottom of the shaft. When the upper and lower columns are connected, the two studs in the column connector are respectively inserted into the threaded holes at the two column connection ends. Therefore, when connecting the upper column to the lower column, first screw one end of the column connector into the threaded hole of the lower column, then align the threaded hole at the bottom of the upper column with the stud at the other end of the column connector, and rotate the upper column until the two columns are in complete contact, thus completing the connection. The operation is convenient and quick. It should also be noted that, for ease of shaft assembly, the shaft is designed with a regular hexagonal cross-section, allowing for direct rotation and installation using hexagonal socket head cap screws.

[0010] As a further description of the above technical solution: the insert shaft is a cylindrical structure, and at least one auxiliary through hole is opened on the insert shaft in the radial direction. In this way, when installing the column connector, a rod-shaped tool can be directly inserted into the auxiliary through hole, and then the insert shaft can be directly rotated by the rod-shaped tool.

[0011] As a further description of the above technical solution: the length of the assembly clip is half the height of the side panel and is located in the middle of the side panel. Auxiliary pressure-bearing strips are also engaged in the fastening grooves at both ends of the side panel. The auxiliary pressure-bearing strips are located between the upper and lower assembly clips. Based on this, the auxiliary pressure-bearing strips can form a shear-resistant engaging structure between the upper and lower columns, which can share the shear force of the column connector, thereby preventing the column connector from deforming and ensuring the subsequent disassembly and reuse of the packaging box.

[0012] As a further description of the above technical solution: the end panel and the column are fixedly connected by a plate connector. One end of the plate connector adopts a threaded structure. The threaded end of the plate connector passes through the outer surface of the end panel and into the threaded hole on the column to realize the connection between the end panel and the column.

[0013] As a further description of the above technical solution: a plurality of positioning rods are provided on the side of the end panel that contacts the column, and positioning holes are opened on the end face of the column corresponding to the positions of the positioning rods. When the end panel is connected to the column, the positioning rods are inserted into the positioning holes.

[0014] This invention also discloses a method for using a packaging box, the specific steps of which are as follows: Step 1: Assembly Preparation Based on the structural shape of the workpiece to be guaranteed, determine the overall number of assembly layers and planar shape of the packaging box; Step 2: Column Assembly Based on the overall number of layers of the packaging box, connect the number of columns corresponding to the number of layers of the packaging box. That is, connect the columns to the length corresponding to the number of layers of the packaging box through column connectors, and fix the columns to the corresponding end panel through plate connectors, thus obtaining several end panels for installing four combined columns. Step 3: Lay the packaging box flat and install the side panels. Based on the overall planar shape of the packaging box, lay the end panel with the four assembled columns installed flat to form the planar shape of the packaging box. Then, insert the bottom side panel from top to bottom along the outer edge of the planar shape of the packaging box. After the bottom side panel is engaged, insert the auxiliary pressure strips into the snap-fit ​​grooves at both ends of the side panel. Repeat this process until the top side panel is engaged. Step 4: Overall Assembly In the packaging box with the side panels installed, the corresponding number of assembly strips are inserted from top to bottom into the snap-fit ​​grooves on the two contacting columns, so that all the individual packaging boxes are fully assembled horizontally. Then, the connecting end panel is fixed to the top of each individual packaging box by the plate connector.

[0015] In the above technical solution, the present invention provides a packaging box that can be flexibly combined and its usage method. The packaging box is composed of several standard parts, namely individual packaging boxes. Through the structural design of the individual packaging boxes, the packaging box can be assembled in three-dimensional space according to the shape of the workpiece being packaged. Therefore, after packaging the workpiece, the coverage of the workpiece is better. Moreover, this packaging box structure design makes it suitable for packaging more workpieces. At the same time, the packaging process is simple and uncomplicated. It is especially suitable for irregularly shaped workpieces. In addition, the entire individual packaging box is a modular assembly structure, and the individual packaging boxes are standard parts. Therefore, they can be reused after disassembly, and can still be used for different workpieces during reuse, thus improving the applicability of the packaging box. Attached Figure Description

[0019] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0020] Example 1 like Figure 1-11As shown: This embodiment provides a technical solution: a packaging box that can be flexibly combined and its usage method, which is composed of several individual packaging boxes 1. The several individual packaging boxes 1 are assembled in three-dimensional space to form an internally hollow structure. The individual packaging box 1 includes two parallel end panels 10, four pillars 11 located between the two end panels 10, the pillars 11 being located at the corners of the end panels 10, and four side panels 12 assembled between two adjacent pillars 11. The end panels 10 and the pillars 11, as well as the pillars 11 and the side panels 12, are detachably assembled, so that when the individual packaging boxes 1 are assembled in three-dimensional space, the side panels 12 between two adjacent individual packaging boxes 1 can be removed, so that the internal spaces of adjacent individual packaging boxes 1 are connected. Working Principle: This packaging box is mainly used for packaging irregularly shaped workpieces. Because the workpieces are irregularly shaped, the packaging boxes need to be assembled according to their shape. In use, first determine the required number of individual packaging boxes 1 based on the workpiece's shape, ensuring they correspond to the workpiece's shape and can fully accommodate it. Then, assemble the determined number of individual packaging boxes 1 according to the workpiece's shape to form a structure that can accommodate the workpiece. The specific assembly process is as follows: Assembly Preparation: Determine the overall number of assembly layers and planar shape of the packaging box; One-layer Assembly: Lay the end panel 10 flat to form the planar shape of the packaged box. Next, four columns 11 are installed at the top corner of each end panel 10. After all the columns 11 of the first layer are installed, side panels 12 are installed between the outermost columns 11 of the planar structure formed by the end panels 10, and the two columns 11 that are in contact on the same layer are locked together. Assembly of the second and above layers: Connect the columns 11 of the corresponding layer above all the columns 11 of the first layer, and install the installation method of the first layer, and install the corresponding side panels 12 from bottom to top. Assembly of the top layer: Attach the end panels 10 above the columns 11 of the top layer, and the assembly process is completed.

[0021] In summary, this packaging box is composed of several standard parts (i.e., individual packaging box 1). Through the structural design of individual packaging box 1, the packaging box can be assembled according to the shape of the workpiece being packaged, so that it can correspond to the shape of the workpiece. Therefore, after packaging the workpiece, the coverage of the workpiece is better. Moreover, this packaging box structural design makes it suitable for packaging more workpieces. At the same time, the packaging process is simple and uncomplicated, and it is especially effective for irregularly shaped workpieces.

[0022] Specifically, such as Figure 7 - Figure 8As shown, in order to achieve the assembly between the column 11 and the side panel 12, in this embodiment, the column 11 adopts a regular square prism structure. Each of the four sides of the column 11 is provided with a fastening groove 110. The fastening groove 110 is opened in the vertical direction and extends from the top to the bottom of the column 11. The two sides of the side panel 12 are provided with assembly strips 120 in the vertical direction. The assembly strips 120 can be inserted into the fastening grooves 110 from top to bottom. Based on this, after the column 11 is installed, it is only necessary to align the assembly strips 120 on the side panel 12 with the fastening grooves 110 on the two adjacent columns 11 from the top, and then insert them into the fastening grooves 110 from top to bottom until the bottom of the side panel 12 contacts the end panel 10 located below, thus completing the assembly between the column 11 and the side panel 12.

[0023] Specifically, such as Figure 7 - Figure 8 As shown, in order to enable the side panel 12 to provide tension to the two uprights 11 and improve the overall stability of the packaging box, in this embodiment, the cross-section of the fastening groove 110 and the assembly strip 120 is T-shaped. Therefore, after the side panel 12 is installed, the assembly strip 120 with the T-shaped structure can provide tension to the two uprights 11, thereby increasing the stability of the packaging box assembly.

[0024] Specifically, such as Figure 7 and Figure 10 As shown, in order to achieve the assembly between individual packaging boxes 1, in this embodiment, the individual packaging boxes 1 are connected by interlocking strips 16. The cross-section of the interlocking strips 16 is "H" shaped. When two adjacent individual packaging boxes 1 are spliced, the fastening grooves 110 on the contact surfaces of the two contacting columns 11 in the two adjacent individual packaging boxes 1 are connected to form a closed groove structure with a cross-section of "H". The interlocking strips 16 are inserted into the closed groove structure of "H" shaped from top to bottom, so that the two contacting columns 11 are fastened and connected. Based on this, the two adjacent columns 11 do not need to use other similar bolt structures for connection. They only need to be inserted into the interlocking strips 16, which is convenient and quick to operate.

[0025] like Figure 7 - Figure 11As shown, in order to connect the upper and lower columns 11, in this embodiment, stepped grooves 112 are provided at the center of both ends of the column 11, and threaded holes 113 are provided at the center of the inner part of the stepped grooves 112. The upper and lower columns 11 are detachably connected by a column connector 15. The column connector 15 includes a shaft 150 with a diameter smaller than the inner diameter of the stepped groove 112 and studs 151 integrally formed on the top and bottom of the shaft 150. When the upper and lower columns 11 are connected, the two studs 151 in the column connector 15 are respectively inserted into the threaded holes at the connecting ends of the two columns 11. Based on this, when connecting the upper column 11 to the lower column 11, first screw the stud 151 at one end of the column connector 15 into the threaded hole 113 of the lower column 11, then align the threaded hole 113 at the bottom of the upper column 11 with the stud 151 at the other end of the column connector 15, and rotate the upper column 11 until the two columns 11 are in complete contact, thus completing the connection. The operation is convenient and quick. In addition, it should be noted that in order to facilitate the assembly of the insert shaft 150, the cross-section of the insert shaft 150 is designed as a regular hexagonal structure, which can be directly rotated and installed using an internal hex bolt.

[0026] Specifically, such as Figure 7 - Figure 11 As shown, in order to facilitate the assembly of the insert shaft 150, the insert shaft 150 is a cylindrical structure, and at least one auxiliary through hole 1500 is opened radially on the insert shaft 150. In this way, when installing the column connector 15, a rod-shaped tool can be directly inserted into the auxiliary through hole 1500, and then the insert shaft 150 can be directly rotated by the rod-shaped tool.

[0027] Specifically, such as Figure 7 - Figure 11 As shown, since the shear force between the upper and lower columns 11 is mainly provided by the column connector 15, it is easy to damage the column connector 15, which will affect the disassembly and reuse of the box. In this embodiment, the length of the assembly clip 120 is half the height of the side panel 12 and is located in the middle of the side panel 12. The auxiliary pressure-bearing strip 14 is also engaged in the fastening groove 110 at both ends of the side panel 12. The auxiliary pressure-bearing strip 14 is located between the upper and lower assembly clips 120. Based on this, the auxiliary pressure-bearing strip 14 can form a shear-resistant engagement structure between the upper and lower columns 11, which can share the shear force of the column connector 15, thereby preventing the column connector 15 from deforming and ensuring the subsequent disassembly and reuse of the packaging box.

[0028] Specifically, such as Figure 5 - Figure 9As shown, in order to connect the end panel 10 and the column 11, in this embodiment, the end panel 10 and the column 11 are fixedly connected by a plate connector 13. One end of the plate connector 13 adopts a threaded structure, and the threaded end of the plate connector 13 passes through the outer surface of the end panel 10 into the threaded hole 113 on the column 11 to realize the connection between the end panel 10 and the column 11.

[0029] Specifically, such as Figure 5 - Figure 9 As shown, in order to improve the accurate alignment of the end panel 10 and the column 11 during connection, in this embodiment, a plurality of positioning rods 100 are provided on the side of the end panel 10 that contacts the column 11, and a positioning hole 111 is provided on the end face of the column 11 at the position corresponding to the positioning rod 100. When the end panel 10 and the column 11 are connected, the positioning rod 100 is inserted into the positioning hole 111.

[0030] Example 2 The present invention also discloses a method for using a packaging box, applied to the packaging box in Example 1, the specific steps of which are as follows: Step 1: Assembly Preparation Based on the structural shape of the workpiece to be guaranteed, determine the overall number of assembly layers and planar shape of the packaging box; Step 2: Assemble column 11 According to the overall number of layers of the packaging box, the number of columns 11 corresponding to the number of layers of the packaging box is connected. That is, the columns 11 are connected to the length corresponding to the number of layers of the packaging box through the column connector 15, and the columns 11 are fixed to the corresponding end panel 10 through the plate connector 13, thus obtaining several end panels 10 with four combined columns 11 installed. Step 3: Lay the packaging box flat and install the side panels 12. Based on the overall planar shape of the packaging box, the end panel 10 with the four combined columns 11 already installed is laid flat to form the planar shape of the packaging box. Then, the bottom side panel 12 is inserted from top to bottom along the outer edge of the planar shape of the packaging box. After the bottom side panel 12 is engaged, the auxiliary pressure-bearing strips 14 are inserted into the fastening grooves 110 at both ends of the side panel 12. This process is repeated until the top side panel 12 is engaged. Step 4: Overall Assembly In the packaging box after the side panel 12 is installed, the corresponding number of assembly strips 16 are inserted from top to bottom into the snap-fit ​​grooves 110 on the two contacting columns 11, so that all the individual packaging boxes 1 are fully assembled horizontally, and then the end panel 10 is fixedly connected to the top of each individual packaging box 1 by the plate connector 13.

[0031] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
