Description

Technical Field

[0001] This application relates to the field of packaging boxes for long shaft parts, and more particularly to a packaging box for long shaft parts with an end support structure. Background Technology

[0002] Long shaft parts play a vital role in industrial production, with widespread applications in machinery manufacturing, aerospace, and other fields. To ensure the safety of long shaft parts during transportation and storage, a suitable packaging structure is crucial.

[0003] In related technologies, long shaft-type parts are typically transported by being stored in a long box, the length of which is equal to the length of the part. However, during transport, the long shaft-type parts are prone to lateral movement within the box, which can easily damage them. Utility Model Content

[0004] To reduce the risk of damage to long shaft parts during transportation, this application provides a packaging box for long shaft parts with an end support structure.

[0005] The technical solution provided in this application for a packaging box for long shaft parts with an end support structure is as follows:

[0006] A packaging box for long shaft-type parts with an end support structure includes two boxes. Each box includes a blank plate and a connector. The blank plate includes five support plates that are integrally formed and connected end to end. Every two adjacent support plates are arranged perpendicularly to each other. The connector is integrally formed with one of the support plates at one end of the blank plate. The blank plate has an insertion interface for the connector to be inserted. One box is fitted onto the outside of the other box. Each box has an insertion hole for inserting one end of the part.

[0007] By adopting the above technical solution, this end support structure can effectively fix and protect long shaft parts. Specifically, the special design of the two sleeves allows them to interlock, forming a stable internal space and ensuring that long shaft parts will not shake or shift during transportation or storage. Meanwhile, the one-piece molded blank and plug-in design not only improves the structural stability but also simplifies the assembly process and reduces production costs. Furthermore, the mating method of the plug-in interface further enhances the structural reliability. By placing this end support structure at both ends inside the long box and plugging each end of the long shaft part into the corresponding support structure, the long shaft parts are securely placed inside the storage box, reducing the possibility of damage during transportation.

[0008] Preferably, the inner casing has a limiting port for inserting a connector from the outer casing.

[0009] By adopting the above technical solution, a stable connection between the inner and outer sleeves is achieved. Specifically, the limiting port design allows the connector on the outer sleeve to be accurately inserted into and fixed on the inner sleeve, thereby improving the structural stability of the two sleeves after assembly and reducing the occurrence of loosening or detachment during transportation or use.

[0010] Preferably, each of the sleeves is provided with a through opening that extends horizontally through the sleeve, and when two sleeves are fitted together, the length directions of the two through openings are perpendicular to each other.

[0011] By adopting the above technical solution, stable positioning of the two sleeves during insertion is achieved. The transverse through-hole on each sleeve effectively reduces relative rotation between the sleeves when they are inserted, thanks to the perpendicular arrangement of the two through-holes along their lengths, thus improving the overall structural stability. This design not only simplifies the assembly process but also enhances the packaging box's support for the ends of long shaft-like parts.

[0012] Preferably, the end of the connector away from the blank is provided with two limiting plates. When the connector is inserted into the insertion interface, the two limiting plates bend relative to each other and pass through the insertion interface.

[0013] By adopting the above technical solution, two limiting plates are set at the end of the connector away from the blank plate, so that when the connector is inserted into the interface, the two limiting plates can bend relative to each other and pass through the interface, thereby effectively enhancing the connection stability between the connector and the interface, reducing the occurrence of the connector accidentally falling off the interface during use, and improving the reliability of the overall structure.

[0014] Preferably, a paper tube is connected to the sleeve, and the paper tube is inserted into the socket and simultaneously connected to two sleeves.

[0015] By adopting the above technical solution, the paper tube configuration effectively enhances the overall structural stability of the box. Simultaneously, by inserting it into the socket and connecting it to two boxes at the same time, the relative position between the two boxes is fixed. Furthermore, paper tubes with different inner diameters can be easily replaced, thus adapting to long shaft parts of different sizes and improving the versatility and flexibility of the packaging box. The insertion design between the paper tube and the box simplifies the replacement operation, eliminating the need for adjustment or modification of the box itself, further enhancing ease of use.

[0016] Preferably, the outer wall of the paper tube is fixedly connected with a reinforcing plate, and each reinforcing plate abuts against the inner wall of the insertion hole.

[0017] By adopting the above technical solution, each reinforcing plate abuts against the inner wall of the insertion hole, which significantly enhances the connection strength between the paper tube and the sleeve. Furthermore, when it is necessary to replace paper tubes with different inner diameters to accommodate long shaft parts of different specifications, only the paper tube with a reinforcing plate of appropriate width needs to be replaced; there is no need to change the wall thickness of the paper tube itself.

[0018] Preferably, the paper tube comprises paperboard, the ends of which are glued or nailed together.

[0019] By adopting the above technical solution, the paper tube is formed by bonding or nailing the ends of the cardboard together. This structure can ensure that the paper tube has good stability and strength, while facilitating production and assembly.

[0020] Preferably, both ends of the outer casing are integrally formed with reinforcing plates, each reinforcing plate has a connecting tongue at one end, and each reinforcing plate is vertically bent. Both sides of the inner casing have connecting ports, and each connecting tongue is inserted into a corresponding connecting port.

[0021] By adopting the above technical solution, the reinforcing plates integrally formed at both ends of the outer casing can enhance the overall structural strength of the casing. The connecting tongue set at one end of the reinforcing plate is inserted into the connecting ports opened on both sides of the inner casing, making the connection between the inner and outer casings more stable and effectively reducing the occurrence of relative movement or separation between the two casings.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By adopting a two-box structure design and utilizing the cooperation of plug-in connectors and interfaces, the end support structure can be quickly assembled and stably connected, effectively improving the reliability of end protection for long shaft parts;

[0024] 2. The insertion hole design on the box can accurately position both ends of long shaft parts, reducing the possibility of displacement of long shaft parts during transportation, thereby ensuring the safety and integrity of the parts;

[0025] 3. The nesting relationship between the inner and outer boxes, combined with the setting of the limiting port, not only enhances the stability of the overall structure, but also simplifies the assembly process, achieving a balance between convenience and stability.

[0030] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0031] This application discloses a packaging box for long shaft-type parts with an end support structure. (Refer to...) Figure 1 and Figure 2 The packaging box for long shaft parts includes two interlocking boxes 1. Each box 1 includes a blank plate 11 and a connector 12. The blank plate 11 includes five integrally formed support plates 111, which are connected end to end in sequence.

[0032] Reference Figure 2 and Figure 3 Each pair of adjacent support plates 111 are arranged perpendicularly to each other. The connector 12 is integrally formed with one of the support plates 111 at one end of the blank plate 11. The blank plate 11 has an insertion interface 112 for the connector 12 to be inserted. The support plates 111 at both ends of the blank plate 11 are stacked on each other, and the connector 12 is inserted into the insertion interface 112.

[0033] Two limiting plates 2 are provided at the end of the connector 12 away from the blank plate 11. When the connector 12 is inserted into the insertion interface 112, the two limiting plates 2 are bent relative to each other and pass through the insertion interface 112. When the connector 12 is inserted into the insertion interface 112, each limiting plate 2 is used to prevent the connector 12 from disengaging from the insertion interface 112.

[0034] By setting the limiting plate 2, the connection strength between the connector 12 and the interface 112 is significantly improved, reducing the occurrence of loosening between the connector 12 and the interface 112 due to vibration during transportation.

[0035] One of the sleeves 1 is fitted onto the outside of the other sleeve 1. Each sleeve 1 has an insertion hole 13 for inserting one end of a long shaft-type part. This achieves the effect of enhancing overall stability and adaptability through the double-layer sleeve 1 structure, while also facilitating rapid assembly.

[0036] The blank 11 can be made of materials such as cardboard, plastic sheet, or composite material. In this embodiment, the blank 11 is preferably cardboard, which is lightweight and inexpensive, making it suitable for mass production. The connection between the support plates 111 is a one-piece molding process to ensure the integrity of the structure. For example, a die-cutting process can be used to directly cut and fold the blank from a single sheet of cardboard, without the need for additional gluing or nailing, thereby improving production efficiency.

[0037] The inner casing 1 has a limiting port 14 for the insertion of the connector 12 on the outer casing 1. When the connector 12 on the outer casing 1 is inserted into the corresponding connector 112, the connector 12 on the outer casing 1 is simultaneously inserted into the limiting port 14. This design further enhances the connection stability between the two casings 1 and reduces the possibility of casings 1 separating due to vibration during transportation.

[0038] Each sleeve 1 is provided with a through opening 15 that extends horizontally through the sleeve 1. When two sleeves 1 are fitted together, the length directions of the two through openings 15 are set perpendicular to each other.

[0039] The special design of the through-hole 15 allows the two sleeve boxes 1 to form a "cross" structure when they are fitted together, further enhancing the overall stability. In addition, the presence of the through-hole 15 also facilitates the interlocking of the two sleeve boxes 1 to complete the assembly.

[0040] Reference Figure 2 and Figure 3 A paper tube 3 is connected to the sleeve 1. The paper tube 3 is inserted into the socket 13 and simultaneously connected to two sleeves 1. The paper tube 3 is made of cardboard, with the ends of the cardboard glued or nailed together to form a cylindrical structure. Multiple reinforcing plates 4 are fixedly connected to the outer wall of the paper tube 3. The multiple reinforcing plates 4 are evenly distributed around the paper tube 3, and each reinforcing plate 4 abuts against the inner wall of the socket 13.

[0041] Both ends of the outer casing 1 are integrally formed with reinforcing plates 5. Each reinforcing plate 5 has a connecting tongue 51 at one end. Each reinforcing plate 5 is vertically bent. Both sides of the inner casing 1 are provided with connecting ports 16. Each connecting tongue 51 is inserted into a corresponding connecting port 16.

[0042] The introduction of paper tube 3 and reinforcing plate 4 further enhances the overall strength and stability of the packaging box for long shaft parts. The introduction of paper tube 3 not only increases the rigidity of the insertion hole 13 but also provides additional cushioning, effectively reducing the risk of damage caused by impacts during transportation. The reinforcing plate 4 further strengthens the connection between paper tube 3 and the sleeve 1, ensuring the entire structure maintains good performance under complex working conditions. The design of reinforcing plate 5 and connecting tongue 51 further optimizes the connection method of the double-layer sleeve 1, making the overall structure more compact and reliable.

[0043] The implementation principle of a packaging box for long shaft parts with an end support structure according to an embodiment of this application is as follows: The design of the double-layered box 1 ensures the stability of the ends of the long shaft parts while achieving rapid assembly. The nesting relationship of the double-layered box 1 makes the overall structure more compact, reducing the risk of displacement due to vibration or impact during transportation. Simultaneously, the mating method between the connector 12 and the interface 112 is simple and reliable, allowing assembly to be completed without additional tools, significantly improving operational efficiency.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
