Description

Technical Field

[0001] This utility model relates to the field of mechanical parts packaging technology, and in particular to a rust-proof packaging box for bearing and gear parts. Background Technology

[0002] Bearings, gears, and other high-precision metal parts are widely used in modern industry. Their surface finish and dimensional accuracy directly affect the performance and service life of the entire equipment. Therefore, these parts must be effectively packaged during storage and distribution to prevent damage during transportation or corrosion in humid environments.

[0003] Currently, physical protection for such parts typically involves filling with versatile cushioning materials, such as foam boards and bubble wrap. However, for irregularly shaped and heavy bearings or gears, these general-purpose materials are insufficient to provide effective fixation. The parts are prone to displacement and shaking within the packaging box, leading to collisions between parts or between parts and the box walls, causing irreversible physical damage such as surface scratches, bumps, and even a decrease in precision.

[0004] In terms of rust prevention, traditional methods often involve applying rust-preventive oil or grease to the surface of parts. While this method offers some rust prevention, it is cumbersome to operate, and it is difficult to ensure uniform coverage of complex surfaces such as gear teeth. Furthermore, parts must undergo a complex cleaning process before use, increasing additional time and labor costs. Another method is to place desiccant packets inside the packaging. However, desiccants have limited moisture absorption capacity and their effect is passive; their rust-preventive effect is significantly reduced if the ambient humidity is too high or the storage time is too long.

[0005] Current technologies often treat physical shock absorption and chemical rust prevention as two separate issues, lacking an integrated packaging solution that can efficiently combine the two. Packaging boxes either focus on cushioning while neglecting the need for active rust prevention, or they employ rust prevention measures but have poor physical fixation, leaving precision parts still facing the dual risks of physical damage and chemical corrosion during distribution.

[0006] Therefore, this utility model proposes a rust-proof packaging box for bearing and gear parts to address the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems existing in the rust-proof packaging boxes for bearing and gear parts, such as poor physical fixation of precision metal parts, easy shaking and collision, lack of active and reliable rust-proof environment, and easy corrosion, this utility model aims to provide a rust-proof packaging box for bearing and gear parts with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a rust-proof packaging box for bearing and gear parts, comprising: the packaging box body; the packaging box top cover, which is detachably fitted onto the packaging box body, and the packaging box body and the packaging box top cover together form the placement cavity; and the shockproof component, which is housed within the placement cavity.

[0009] The shock-absorbing component includes the shock-absorbing cotton, which has positioning grooves for accommodating bearing and gear parts.

[0010] Furthermore, the walls of both the packaging box body and the packaging box top cover are configured with the rust-proof component, which includes the VIC rust-proof layer disposed on the innermost side and facing the placement cavity.

[0011] Preferably, in order to improve the closing stability and sealing of the packaging box top cover and the packaging box body, the bottom of the packaging box top cover is provided with the insert plate, and the packaging box body is provided with the corresponding slot for engaging the insert plate.

[0012] Preferably, to ensure that the shock-absorbing component has excellent cushioning resilience and moisture resistance, the shock-absorbing cotton is made of EPE pearl cotton material.

[0013] Preferably, in order to construct a complete multi-layer protective structure, the rust-proof component further includes the barrier layer disposed on the outside of the VIC rust-proof layer, the barrier layer being used to prevent air intrusion.

[0014] Furthermore, the rust-proof component also includes a waterproof layer disposed on the outside of the barrier layer, the waterproof layer being used to block external moisture.

[0015] In one specific implementation, the waterproof layer is a BOPP film, and to ensure a strong bond, the waterproof layer is hot-pressed onto the outside of the barrier layer.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem of poor protection effect caused by the separation of physical protection and chemical rust prevention measures for precision metal parts in the prior art by setting shock-absorbing cotton with positioning grooves inside the packaging box and setting the box wall of the packaging box as a multi-layer rust-proof component containing a volatile rust-proof layer. It achieves the technical effect of integrating shock-absorbing fixation and active rust prevention functions into one, providing dual and efficient comprehensive protection for the parts.

[0017] 2. This utility model solves the problem that general-purpose cushioning materials in the prior art cannot effectively fix irregular or heavy parts, causing shaking and collisions during transportation, by opening positioning grooves on the shock-absorbing cotton that match the shape of the parts. It achieves the technical effect of precise positioning and physical fixation of parts, significantly enhances the stability during transportation, and effectively avoids bumps and damage.

[0018] 3. This utility model solves the problems of uneven application and difficulty in cleaning of traditional rust-preventive grease and the limited and passive moisture-proof ability of desiccants by setting a volatile rust-preventive layer on the inner wall of the packaging box. It achieves the technical effect of actively releasing rust-preventive gas and making it evenly adsorbed on all surfaces of the parts to form a comprehensive, clean and long-lasting rust-preventive protective film.

[0019] 4. This utility model solves the problem that ordinary packaging boxes are easily affected by the external environment and cannot maintain a stable internal rust-proof environment by designing the packaging box wall as a multi-layer composite structure consisting of a waterproof layer, a barrier layer and a volatile rust-proof layer. It achieves the technical effect of isolating moisture and air from the outside and building a stable and sealed rust-proof system from the inside out, ensuring the reliability and durability of the rust-proof function.

[0023] Please refer to Figures 1 to 4 This utility model provides a rust-proof packaging box for bearing and gear parts, which aims to solve the problem that precision metal parts are easily corroded by moisture during transportation and storage, and are easily damaged by shaking and collision.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the rust-proof packaging box for bearing and gear parts includes a box body 1 and a box top cover 2 that is detachably fitted onto the box body 1; the box body 1 and the box top cover 2 together form a placement cavity 7; as shown... Figure 3 As shown, the cavity 7 contains a shock-absorbing component 5; as Figure 2 As shown, the walls of both the main body 1 and the top cover 2 of the packaging box are equipped with rust-proof components 6.

[0025] To solve the above technical problems, the shock-absorbing component 5 and the rust-proof component 6 are designed with specific structures in combination; Please refer to the following carefully. Figure 3 and Figure 4 The shockproof component 5 includes shockproof cotton 501, which is housed in the placement cavity 7. The shockproof cotton 501 has a positioning groove 502 for accommodating bearing and gear parts. The positioning groove 502 is used to physically fix the parts during transportation to prevent them from shaking or shifting. The shockproof cotton 501 is made of EPE pearl cotton material. Please refer to the following carefully. Figure 2 The rust-proof component 6 is used to form the box wall of the packaging box body 1 and the packaging box top cover 2. The rust-proof component 6 is made of multiple layers of materials, including a VIC rust-proof layer 603 disposed on the innermost side and facing the placement cavity 7. The VIC rust-proof layer 603 is used to volatilize rust-proof substances in the placement cavity 7 and form a protective film on the metal surface. The rust-proof component 6 also includes a barrier layer 602 disposed on the outside of the VIC rust-proof layer 603. The barrier layer 602 is used to prevent air from entering and damaging the rust-proof environment. The rust-proof component 6 also includes a waterproof layer 601 disposed on the outside of the barrier layer 602. The waterproof layer 601 is used to effectively block the intrusion of external moisture. The waterproof layer 601 is a BOPP film and is bonded to the outside of the barrier layer 602 by hot pressing.

[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, in order to achieve stable installation of the packaging box top cover 2 and the packaging box body 1, please refer to... Figure 3 The top cover 2 of the packaging box has an insert plate 3 at the bottom, and the main body 1 of the packaging box has a corresponding slot 4 for attaching the insert plate 3. As another preferred embodiment, in order to improve the cushioning and rebound performance of the shock-absorbing component 5, the shock-absorbing cotton 501 is preferably made of EPE pearl cotton material. As a further preferred embodiment, to enhance the overall protective capability of the rust-preventive component 6, please refer to... Figure 2 The barrier layer 602 is disposed on the outside of the VIC anti-rust layer 603, and the waterproof layer 601 is disposed on the outside of the barrier layer 602; more preferably, the waterproof layer 601 is a BOPP film and is fixed to the outside of the barrier layer 602 by hot pressing.

[0027] The working principle of this rust-proof packaging box for bearing and gear parts is as follows: The metal parts are placed in the positioning groove 502 on the shock-absorbing cotton 501 of the shock-absorbing component 5. The shock-absorbing cotton 501 provides cushioning protection, while the positioning groove 502 physically fixes the parts to prevent shaking and displacement. Subsequently, the insert plate 3 at the bottom of the top cover 2 of the packaging box is snapped into the slot 4 of the body 1 of the packaging box, so that the body 1 of the packaging box and the top cover 2 of the packaging box are tightly closed to form a sealed placement cavity 7. In a sealed state, the rust-proof component 6 that forms the box wall plays a role. The VIC rust-proof layer 603 located on the innermost side continuously volatilizes rust-proof substances into the placement cavity 7. The rust-proof substances form a protective film on the surface of the metal parts to prevent rust from occurring. At the same time, the barrier layer 602 located outside the VIC rust-proof layer 603 and the waterproof layer 601 located outside the barrier layer 602 in the rust-proof component 6 work together to block the intrusion of external air and moisture, ensuring the stability of the rust-proof environment inside the placement cavity 7. This invention solves the technical problem of precision parts being easily damaged and corroded during transportation and storage by combining the physical fixing and buffering of the shock-absorbing component 5 with the chemical rust prevention and protection of the rust-preventing component 6.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
