Description

Technical Field

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

[0002] Packaging boxes for shaft parts play an important role in industrial production. They are mainly used to protect and transport shaft parts, reducing the occurrence of damage to parts due to collisions, squeezing, and other reasons during logistics.

[0003] With the development of the manufacturing industry, the packaging requirements for shaft parts are becoming increasingly stringent. These requirements must not only ensure safety during transportation but also meet demands for environmental protection, economy, and convenience. Currently, there is a wide variety of packaging boxes available on the market.

[0004] However, during the folding and fixing process, the structural stability of the packaging box is difficult to guarantee, and it is easy for it to loosen or deform, thus affecting the protection of shaft parts. Utility Model Content

[0005] To ensure effective protection for shaft-type parts, this application provides a packaging box for shaft-type parts.

[0006] The technical solution for a packaging box for shaft parts provided in this application is as follows:

[0007] A packaging box for shaft parts includes a base plate and a first side plate and a second side plate fixed at both ends of the base plate in the width direction. A third side plate is fixedly connected to the end of the first side plate away from the base plate, and a fourth side plate is fixedly connected to the end of the second side plate away from the base plate. End plates are fixedly connected to both ends of the base plate in the length direction. A limiting plate is fixedly connected to both ends of each end plate. A plug-in plate is fixedly connected to the end of the third side plate away from the first side plate. A plug-in hole is provided between the second side plate and the fourth side plate. When folded, each end plate is perpendicular to the base plate, and the limiting plate is perpendicular to the base plate and the end plate. The first side plate and the second side plate are both perpendicular to the base plate. The fourth side plate is bent towards the direction of the second side wall and the two adjacent limiting plates are sandwiched between the fourth side plate and the second side plate. The third side plate is perpendicular to the first side plate, and the plug-in plate is plugged into the plug-in hole.

[0008] By adopting the above technical solution, the packaging box can firmly clamp the two adjacent limiting plates during folding by bending the fourth side plate, effectively reducing the occurrence of loosening and displacement of the limiting plates during transportation or storage, thereby improving the overall stability of the packaging box. At the same time, the matching design of the insertion plate and insertion hole not only enables quick positioning and connection between the side plates, but also enhances the structural strength of the packaging box, ensuring effective protection for shaft-type parts.

[0009] Preferably, a fixing hole is provided between the base plate and the second side plate, and a fixing tongue is provided at the end of the fourth side plate away from the second side plate, and the fixing tongue is inserted into the fixing hole.

[0010] By adopting the above technical solution, the cooperation between the fixing hole and the fixing tongue enables a stable connection between the fourth side plate and the bottom plate, thereby improving the overall structural stability of the packaging box. After the fixing tongue is inserted into the fixing hole, it effectively prevents the fourth side plate from shifting during folding, ensuring precise positioning of the packaging box during assembly. This design simplifies the assembly process of the packaging box while enhancing its protection of shaft-like parts.

[0011] Preferably, an auxiliary hole is provided between the plug-in plate and the third side plate, an auxiliary plate is fixedly connected to one end of the second side plate near the fourth side plate, a through hole is provided on the fourth side plate for the auxiliary plate to pass through, and the end of the auxiliary plate away from the second side plate is bent toward the third side plate and plugged into the auxiliary hole.

[0012] By adopting the above technical solution, the auxiliary holes and auxiliary plates enhance the structural stability of the packaging box. Specifically, the auxiliary plate passes through the through-hole on the fourth side plate and bends towards the third side plate before inserting into the auxiliary hole. This design effectively reduces the possibility of the third and fourth side plates loosening or detaching during use, thus ensuring that the packaging box maintains good sealing and protective performance when transporting and storing shaft parts. Furthermore, this design simplifies the assembly process of the packaging box and improves operational convenience.

[0013] Preferably, the third side plate has a semi-circular hole that communicates with the auxiliary hole.

[0014] By adopting the above technical solution, a semi-circular hole communicating with the auxiliary hole is provided on the third side plate. This allows the auxiliary plate to enter the auxiliary hole more smoothly when it is inserted, reducing resistance during the insertion process and improving the efficiency and convenience of packaging box assembly. At the same time, the presence of the semi-circular hole also facilitates the quick separation of the auxiliary plate from the auxiliary hole when disassembling or adjusting the packaging box, enhancing the operability and flexibility of the packaging box.

[0015] Preferably, each end plate is fixedly connected to a mounting plate at the end away from the bottom plate. When folded, the mounting plate bends perpendicular to the end plate and is used to abut against the inner side of the third side plate.

[0016] By adopting the above technical solution, the mounting plate can provide additional support when folded, making the third side plate more stable in the folded state, thereby improving the overall structural stability of the packaging box.

[0017] Preferably, the end of the plug-in plate away from the third side plate is chamfered, and the end of the auxiliary plate away from the second side plate is also chamfered.

[0018] By adopting the above technical solution, the chamfering effectively reduces the frictional resistance between the connector plate and the auxiliary plate during the insertion process, thereby improving assembly efficiency. Specifically, the chamfering makes it easier to align the connector plate with the auxiliary hole and the auxiliary plate with the through hole, thus simplifying the assembly operation of the packaging box.

[0019] Preferably, the end of the fixing tongue away from the fourth side plate has a chamfer.

[0020] By adopting the above technical solution, when the fixing tongue is inserted into the fixing hole, the chamfer can guide the fixing tongue to be smoothly inserted into the fixing hole, reducing the alignment difficulty in the insertion process and improving assembly efficiency.

[0021] Preferably, the first side plate is provided with two connecting tongues, and the two limiting plates near the first side plate are provided with connecting holes. One connecting tongue corresponds to one connecting hole and the connecting tongue is used to be inserted into the connecting hole.

[0022] By adopting the above technical solution, the two connecting tongues on the first side plate can be inserted into the connecting holes on the two limiting plates near the first side plate, thereby enhancing the connection stability between the first side plate and the limiting plates, reducing the occurrence of loosening of the packaging box during transportation or handling, and improving the reliability of the overall structure.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The structural strength of the packaging box has been enhanced, ensuring effective protection for shaft-type parts;

[0025] 2. The assembly process of the packaging box has been simplified, improving ease of operation;

[0026] 3. The packaging box can be assembled through simple folding and insertion operations. The operation is convenient and requires no additional tools, which meets the requirements of efficiency and economy in industrial production, while optimizing the protection effect of shaft parts.

[0032] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0033] This application discloses a packaging box for shaft parts. (Refer to...) Figure 1 and Figure 2 The packaging box for shaft parts is integrally formed after being cut from cardboard. The packaging box for shaft parts includes a base plate 1, a first side plate 2, a second side plate 3, a third side plate 4, a fourth side plate 5, and two end plates 6. The first side plate 2 and the second side plate 3 are fixed to both ends of the base plate 1 in the width direction. The third side plate 4 is fixedly connected to the end of the first side plate 2 away from the base plate 1. The fourth side plate 5 is fixedly connected to the end of the second side plate 3 away from the base plate 1.

[0034] Both ends of the base plate 1 along its length are fixedly connected to end plates 6, and both ends of each end plate 6 along the width of the base plate 1 are fixedly connected to limiting plates 61. A plug-in plate 41 is fixedly connected to the end of the third side plate 4 furthest from the first side plate 2, and an elongated plug-in hole 31 is provided between the second side plate 3 and the fourth side plate 5. A mounting plate 62 is fixedly connected to the end of each end plate 6 furthest from the base plate 1.

[0035] Reference Figure 1 and Figure 2 When folding, fold each end plate 6 until each end plate 6 is perpendicular to the bottom plate 1, then bend the limiting plate 61 until the limiting plate 61 is perpendicular to both the bottom plate 1 and the end plate 6. (Refer to...) Figure 1 and Figure 3 Fold the first side plate 2 and the second side plate 3 so that both the first side plate 2 and the second side plate 3 are perpendicular to the bottom plate 1. Bend the fourth side plate 5 toward the direction of the second side plate 3 and sandwich the two limiting plates 61 adjacent to the second side plate 3 between the fourth side plate 5 and the second side plate 3.

[0036] Reference Figure 1 and Figure 4 Each mounting plate 62 is bent perpendicularly to the end plate 6 towards the bottom plate 1, and the third side plate 4 is bent perpendicular to the first side plate 2. At this time, the mounting plate 62 abuts against the inner side of the third side plate 4, and the plug plate 41 is plugged into the plug hole 31. This completes the folding of the packaging box. The operation is simple, convenient and secure.

[0037] Reference Figure 1 and Figure 4 The two corners of the plug plate 41 away from the third side plate 4 are provided with chamfers 7, which makes it easier for the plug plate 41 to be plugged into the plug hole 31.

[0038] Reference Figure 1 and Figure 3 Two fixing holes 11 are provided between the base plate 1 and the second side plate 3, and two fixing tongues 51 are provided at the end of the fourth side plate 5 away from the second side plate 3. One fixing tongue 51 corresponds to one fixing hole 11, and the fixing tongue 51 is inserted into the fixing hole 11. This makes it easy to firmly clamp the two limiting plates 61 adjacent to the second side plate 3 between the fourth side plate 5 and the second side plate 3.

[0039] The fixing tongue 51 has chamfers 7 at both corners away from the fourth side plate 5. The chamfers 7 not only improve the convenience of insertion, but also play a guiding role in the insertion process, reducing the occurrence of damage to the fixing tongue 51 due to impact.

[0040] Reference Figure 1 and Figure 3 An auxiliary hole 411 is provided between the insertion plate 41 and the third side plate 4. The auxiliary hole 411 is an elongated hole. An auxiliary plate 32 is fixedly connected to one end of the second side plate 3 near the fourth side plate 5. The fourth side plate 5 has a through hole 52 for the auxiliary plate 32 to pass through. After the insertion plate 41 is inserted into the insertion hole 31, the end of the auxiliary plate 32 away from the second side plate 3 is bent towards the third side plate 4 and inserted into the auxiliary hole 411. This design provides additional support points for the packaging box, further improving the stability of the overall structure.

[0041] The auxiliary plate 32 has chamfers 7 at both corners away from the second side plate 3, so that the auxiliary plate 32 can be easily inserted into the auxiliary hole 411.

[0042] The third side plate 4 has a semi-circular hole 42 that communicates with the auxiliary hole 411, which facilitates the quick separation of the auxiliary plate 32 from the auxiliary hole 411 when disassembling or adjusting the packaging box, thereby enhancing the operability and flexibility of the packaging box.

[0043] Reference Figure 1 and Figure 2 The first side plate 2 is provided with two connecting tongues 21, one connecting tongue 21 corresponds to one limiting plate 61. The two limiting plates 61 adjacent to the first side plate 2 are provided with connecting holes 611. The connecting holes 611 are elongated holes, and each connecting tongue 21 is inserted into a corresponding connecting hole 611.

[0044] The implementation principle of a packaging box for shaft parts according to an embodiment of this application is as follows: a complete packaging box frame is formed by combining a base plate 1, side plates, end plates 6, and a plug-in structure. The components are fixedly connected through plug-in and clamping methods, reducing the operational complexity and increased costs associated with traditional packaging boxes that rely on glue or screws for fixation. In particular, the cooperation between the plug-in plate 41 and the plug-in hole 31, and the clamping structure between the fourth side plate 5 and the limiting plate 61, effectively reduce the possibility of the packaging box loosening due to vibration or external forces during transportation, thereby ensuring the safety of the shaft parts. Furthermore, the entire structure is rationally designed, easy to disassemble and assemble, and meets multiple requirements for environmental protection, economy, and convenience.

[0045] 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.
