Description

Technical Field

[0001] The present invention relates to the technical field of boxes and bags, and in particular to a rack box. Background Art

[0002] Compared to metal materials, plastics have advantages such as light weight and strong corrosion resistance, and are widely used in some special applications. However, at the same time, the strength and rigidity of plastic materials are generally relatively low, which brings certain challenges to the design of the box structure.

[0003] To overcome the structural performance disadvantages of plastic enclosures, injection molding is widely used within the industry. Through precise mold design and controlled injection molding processes, complex plastic components can be molded while ensuring dimensional accuracy and aesthetic quality. This injection molding process not only improves production efficiency but also leverages the molding advantages of plastic materials.

[0004] For example, patent application number CN201820984314.3 discloses a modular box body assembly stable connection structure, including a symmetrically installed top beam and a symmetrically installed bottom beam; the bottom beam includes a sliding rail part, a lower beam waist, and a fixing part, the lower beam waist between the symmetrically installed bottom beams is fitted together, and the middle part of the lower beam waist is provided with a concave lower beam waist folded surface, the top beam includes a drainage groove, an upper beam waist, and a clamping part, the upper beam waist between the symmetrically installed top beams is fitted together, and the middle part of the upper beam waist is provided with a concave upper beam waist folded surface, an upper pad and a lower pad that are relatively fitted together are provided between the bottom beam and the top beam, the fixing part is placed in the upper pad, and pads that carry symmetrical fixing parts and symmetrical drainage grooves are placed in the upper pad and the lower pad.

[0005] The above solution realizes an integrated molding design through a reasonable design of the box, and combines it with corresponding processing methods to achieve simple processing, mass production, improve the sealing of the box, and increase durability and safety. However, in this solution, faced with customized boxes of various specifications, each specification of box needs to be designed separately and according to the design dimensions, the box processing is still carried out through traditional processes such as cutting and bending. Obviously, the production efficiency and production cost are not ideal, and there is room for optimization. Summary of the Invention

[0006] In response to the problem mentioned in the background technology that the box structure in the prior art is single and each specification requires separate design of dimensions and mold opening, resulting in high costs, the present invention provides a rack box, the box cover and box body each include side parts that can be added or removed, allowing manufacturers to adjust the capacity and height of the rack box before manufacturing according to the size and quantity of the objects, thereby meeting the storage needs of objects of different specifications.

[0007] The second object of the present invention is to solve the problem of insufficient strength of the modular box structure.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions: A rack box comprises: a box body; one or two covers; the cover includes any number of cover side pieces; the box body includes body side pieces corresponding to the cover side pieces; the cover and box body are both welded together, and the cover and body are detachably connected. The size and volume of the rack box can be adjusted by adding or removing cover and body side pieces during manufacturing. This solution provides a fast, flexible, and cost-effective solution to meet market demand for storing items of varying types and sizes. It improves storage efficiency, reduces transportation and storage costs, and offers greater compatibility and adaptability. Compared to common solutions, this rack box offers the advantage of high customizability and scalability. Traditional rack boxes are often fixed to specific dimensions and volumes, making them difficult to adjust based on demand. This solution, however, allows manufacturers to flexibly add or remove side pieces to adjust the size of the rack box according to actual needs, reducing resource waste and improving product competitiveness. The design of the chassis and lid allows for assembly through welding and removable connections, ensuring structural stability while providing sufficient flexibility. Furthermore, the side panels allow the rack box's dimensions to be adjusted to the specific needs of the item, rather than being fixed. This modular design also opens up possibilities for future product upgrades and functional expansion. For example, the field could further optimize the welding process, improve the durability and sealing of the chassis and lid, or develop a wider variety of side panels to accommodate more diverse storage needs.

[0009] Preferably, the box is assembled from two halves welded together using hot plate welding, each half comprising side walls and a bottom plate. Half-boxes welded together using hot plate welding can reduce production time, lower costs, and improve production efficiency. The design of the half-box also allows for quick adjustment of the box's dimensions to suit different storage needs. Furthermore, the use of welding technology provides a stronger structural connection, reducing the risks associated with other connection methods such as screws or rivets. This solution enhances the box's load-bearing capacity and improves its overall durability and service life. Traditional boxes may be connected using bolts or rivets, which can introduce weak points at the joints. Hot plate welding effectively avoids this problem. This welded half-box provides greater structural integrity and stability, reducing potential errors during assembly without sacrificing production efficiency and cost-effectiveness. Furthermore, those skilled in the art can further expand the design of the half-boxes, for example, developing half-boxes of different shapes to accommodate the storage needs of objects of specific shapes.

[0010] Furthermore, the box lid includes two corner lids; the lid side pieces, if present, are positioned between the two corner lids. These body and lid side pieces allow the box body and lid to fit tightly together, forming a stable, integrated structure. The corner lid design cleverly utilizes the space in the corners, improving the box's load-bearing capacity and overall rigidity. The lid side pieces allow the lid to fit tightly against the box's side walls while maintaining an appropriate gap, enhancing overall sealing and stability. The corner lids provide structural strength without interfering with the adjustment and variability of the box's height and capacity. The corner lids enhance the stability of the box during loading and unloading, reducing bending and deformation. Furthermore, the added lid side pieces provide additional support points for the lid, allowing it to withstand greater loads without deformation, significantly improving the durability and practicality of the rack box. The tight fit between the corner lids and lid side pieces enhances the box's sealing and protection, reducing the risk of damage to items inside during transportation or storage. In traditional rack enclosure designs, the enclosure body and lid are typically molded as a single piece, requiring re-molding and re-processing to adjust size or height. However, this solution utilizes a modular design with corner lids and lid side panels, allowing the enclosure body and lid to be quickly adjusted during manufacturing as needed, enhancing the versatility of the rack enclosure.

[0011] Furthermore, the corner lid includes two vertically spaced tops connected by a chamfered transition. The corner lid is connected by two vertically spaced tops, with the chamfered transition forming a stable joint. This design not only enhances the lid's structural stability but also simplifies its manufacturing and assembly process. The corner lid, as a connecting element, effectively connects the lid side pieces to the main body, improving the overall load-bearing capacity and durability of the box. The vertical layout of the corner lid ensures smoother opening and closing, reducing stress concentration caused by uneven weight on the lid side pieces. Furthermore, the chamfered transition not only enhances the appearance but also reduces potential stress concentration points during welding, improving weld quality. The number of lid side pieces can be adjusted according to actual needs during production, enabling customization of boxes of varying sizes and shapes. Furthermore, the vertical layout and chamfered transition of the corner lid not only enhance the lid's structural stability but also provide a better seal, preventing the penetration of liquids or fine particles.

[0012] Furthermore, half-side box covers of different shapes or thicknesses can be developed to match box bodies with corresponding structures to meet the storage needs of special shapes or heavy-loaded items.

[0013] Furthermore, the side members of the cabinet body comprise a main plate and concave panels on either side of the main plate. The main plate, combined with the corner cover, forms transverse and longitudinal ribs. The ribs formed by the main plate and concave panels increase the local thickness of the material, improving the bending and torsional resistance of the cabinet cover side members. The interaction of the transverse and longitudinal ribs forms a strong network structure that helps distribute and withstand forces from different directions, thereby protecting the contents from damage. This enhances the mechanical performance of the cabinet cover side members, ensuring that the cabinet cover does not deform or damage under heavy loads or in harsh transportation conditions. The concave panels also reduce material usage without sacrificing structural strength, thereby improving the overall durability and reliability of the rack cabinet. The ribs enable the cabinet cover side members to better withstand and distribute pressure, reducing the risk of damage to items during transportation. This design also improves the sealing performance of the cabinet cover, as the ribs fit more tightly against the edges of the cabinet body. Conventional designs may use ribs oriented in a single direction, which may not provide sufficient support. This solution significantly improves the load-bearing capacity and overall stability of the box cover by combining transverse and longitudinal reinforcement ribs.

[0014] Furthermore, the inner groove forms an inner slot where the inner recessed plate meets the side members of the case lid, and a latch assembly is positioned within the inner slot. By designing the inner grooves at the junction of the inner recessed plate and the case body side members, these grooves accommodate the latch assembly. When the rack case is closed, the latch assembly secures the case lid, ensuring a tight seal between the lid and the case body. When the rack case needs to be opened, the user can operate the latch assembly to release the lid, allowing easy access to the contents. This enhances the practicality and ease of use of the rack case. The inner groove provides a stable position for the latch, ensuring it does not loosen or fall off during use. The latch assembly provides a simple and effective sealing mechanism, preventing the case lid from accidentally opening during transport or storage. The latch assembly prevents the case lid from accidentally opening due to vibration or impact during transport, thereby protecting the contents from damage. Furthermore, the inner groove and latch design enhance the ease of use of the rack case, allowing users to quickly and easily open and close the lid. In addition, the design of the inner slots and latches can also be integrated with other intelligent functions, such as remote control or status monitoring, to achieve a more advanced rack enclosure management system.

[0015] Preferably, the corner cover is provided with a groove, within which a handle is positioned. By designing grooves on the corner cover and placing the handle within these grooves, this design provides a secure grip when carrying the rack case, effectively reducing the burden on the hands during transport and minimizing the risk of finger slippage.

[0016] Preferably, the box is provided with a support frame, with beams arranged along each edge of the box. The beams of the internal support frame effectively disperse external impact and pressure, reducing direct damage to the contents. The beams arranged along the edges of the box help create a stable internal space structure, ensuring greater safety for the contents during transportation or storage. This provides a more stable and reliable internal support structure suitable for storing objects of different types and sizes. The support frame reduces movement of objects within the box, preventing damage caused by vibration or impact. This enhances the protection provided by the rack box for the contents within, particularly during transportation, significantly reducing the risk of damage. Furthermore, the support frame allows for more efficient planning and utilization of the rack box's internal space. Traditional designs may not consider the importance of internal support or use a single support structure, which may not provide adequate protection. However, by arranging the beams along the edges of the box, this solution significantly improves the internal stability and protection of the rack box, achieving the second objective of the present invention.

[0017] Furthermore, a shock-absorbing layer is provided between each frame beam and the box body. By placing a shock-absorbing layer between the frame beams of the support frame and the box body, the impact of external shock, vibration or pressure on the objects inside the box body can be effectively absorbed and alleviated. The provision of the shock-absorbing layer helps to reduce the risk of damage caused by bumps, falls or other external factors during transportation. The use of the shock-absorbing layer can significantly reduce the damage to objects caused by vibration or impact during transportation, and is especially suitable for objects that are sensitive to vibration or fragile. The presence of the shock-absorbing layer not only enhances the stability of the objects inside the box body, but also extends the service life of the objects, especially in application scenarios with high protection requirements, such as the transportation and storage of electronic equipment and precision instruments. By incorporating a shock-absorbing layer into the support structure, this solution not only enhances the practicality of the rack box, but also makes it more suitable for objects that have special requirements for protection during transportation and storage.

[0018] Preferably, the frame beam is formed by interlocking several unit beam segments according to the size of the rack box. The frame beams include a first frame beam extending along the side members of the rack box and a second frame beam extending along the side members of the lid. Both the first and second frame beams consist of unit beam segments of different lengths, and the second frame beam includes the same number of height-adjustable beam segments as the number of lid side members on each side. By interlocking the unit beam segments, the length and height of the frame beams can be flexibly adjusted to suit the size and shape of the rack box. This design allows the rack box to accommodate objects of varying sizes and shapes, providing a high degree of customizability and adaptability. The design of the first and second frame beams ensures a tight connection between the frame beams and the rack box body and lid, providing stable support for the items inside. The use of unit beam segments allows the frame beams to be easily adjusted in length and height to accommodate rack boxes of varying sizes, enhancing product design flexibility and diversity. Furthermore, the height-adjustable beam segment design allows manufacturers to adjust the frame beam height based on the number of lid side members, further optimizing space utilization and improving the adaptability and functionality of the rack box. Manufacturers can select the appropriate rack box size based on their needs and optimize internal space utilization by adjusting the frame beams. This flexibility allows the rack box to be used in a variety of applications, such as logistics, warehousing, and electronic product protection. By utilizing unit beam segments, this solution allows the support frame to be customized to the specific needs of the rack box, enhancing the product's market competitiveness.

[0019] Therefore, the present invention has the following beneficial effects: The modular design allows the size of the rack box body and cover to be adjusted as needed, thereby improving space utilization and reducing material waste.

[0020] The combination of the internal support frame and the shock-absorbing layer effectively absorbs impact during transportation, reduces the risk of damage to items, and improves protection performance.

[0021] The close fit between the corner box cover and the box cover side pieces enhances the structural stability of the rack box and extends its service life.

[0022] The setting of the lock component simplifies the opening and closing operation of the box cover, improves the convenience of use, and at the same time ensures the sealing and prevents accidental opening.

[0023] The adjustable support frame design allows the rack box to accommodate items of different heights and shapes, enhancing the versatility and adaptability of the rack box. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1 like Figure 1 、 3 As shown, a rack box comprises: a box body 2; one or two box covers 1; wherein the box cover comprises any number of box cover side pieces 11, and the inward folding parts 111 at both ends of the box cover side pieces are used to form the outline of the rack box and improve the structural strength; wherein the box body comprises box body side pieces 21 arranged corresponding to the box cover side pieces; wherein the box cover and the box body are formed by welding, and the box cover and the box body are detachably connected. The box body is formed by hot plate welding of two half-box bodies 22, and each half-box body comprises a side wall 23 and a bottom plate 24. The half-box body made by hot plate welding can reduce production time, reduce costs, and improve production efficiency. As Figure 4 As shown, the box cover includes two corner box covers 12; the box cover side member, if any, is arranged between the two corner box covers. The corner box cover includes two vertically distributed cover tops 13, which are connected by a chamfer 14. The corner box covers are connected by the two vertically distributed cover tops, wherein the two cover tops are connected by the chamfer to form a stable joint. Figure 5 As shown, the box side parts include a main board 25 and inner concave plates 26 arranged on both sides of the main board. The main board and the corner box cover are assembled to form transverse reinforcement ribs 27 and longitudinal reinforcement ribs 28.

[0036] The size and volume of the rack box can be adjusted by adding or removing lid and body side pieces during manufacturing. This provides a fast, flexible, and cost-effective solution to meet market demand for storing objects of different types and sizes. This improves storage efficiency, reduces transportation and storage costs, and provides better compatibility and adaptability. Compared to common solutions, this rack box has the advantage of being highly customizable and scalable. Traditional rack boxes are often fixed to specific sizes and volumes, making them difficult to adjust based on demand. This solution allows manufacturers to flexibly add or remove side pieces, thereby changing the size of the rack box, based on actual needs. This reduces resource waste to a certain extent and improves the product's market competitiveness. The design of the body and lid allows for assembly through welding and detachable connections, which ensures the structural stability of the rack box while providing sufficient flexibility. In addition, the side pieces allow the size of the rack box to be adjusted according to the specific needs of the object, rather than being fixed. This modular design also provides possibilities for future product upgrades and functional expansion. For example, the field can further optimize the welding process, improve the durability and sealing of the box body and box cover, or develop more types of side pieces to accommodate more diverse storage needs.

[0037] The design of the half-side box also allows the size of the box to be quickly adjusted to suit different storage needs. In addition, the application of welding technology also provides a stronger structural connection, reducing the risks that may be caused by using other connection methods such as screws or rivets. This solution enhances the load-bearing capacity of the box and improves its overall durability and service life. Traditional boxes may be connected by bolts or rivets, which may introduce weaknesses at the connection, while hot plate welding effectively avoids this problem. This welded half-side box provides higher structural integrity and stability, reduces errors that may occur during the assembly process, and at the same time does not sacrifice production efficiency and cost-effectiveness. In addition, those skilled in the art can further expand the design of the half-side box. For example, half-side boxes of different shapes can be developed to meet the storage needs of objects of specific shapes.

[0038] The cabinet body and lid are tightly fitted together through these side and lid components, forming a solid, integrated structure. The corner lid design cleverly utilizes the corner space, increasing the cabinet's load-bearing capacity and overall rigidity. The lid side components allow the lid to fit tightly against the cabinet sidewalls while maintaining appropriate clearance, enhancing overall sealing and stability. The corner lid provides structural strength without compromising the height and capacity of the cabinet. The corner lid stabilizes the cabinet during loading and unloading, reducing bending and deformation. Furthermore, the added lid side components provide additional support points for the lid, allowing it to withstand greater loads without deformation, significantly improving the durability and practicality of the rack cabinet. The tight fit between the corner lid and lid side components enhances the cabinet's sealing and protection, reducing the risk of damage to contents during transport or storage. In traditional rack cabinet designs, the cabinet body and lid are typically molded as a single piece, requiring re-molding and re-processing to adjust dimensions or height. This solution uses a modular design of the corner box cover and the box cover side parts, so that the box body and the box cover can be quickly adjusted during manufacturing as needed, thereby improving the versatility of the rack box.

[0039] As a connecting element, the corner lid effectively connects the lid side pieces to the main body of the lid, improving the overall load-bearing capacity and durability of the lid. The vertical distribution of the corner lid makes the lid smoother during opening and closing, reducing stress concentration caused by the uneven weight of the lid side pieces. Furthermore, the chamfered transition connection not only provides a better appearance but also reduces stress concentration points that may occur during welding, thereby improving weld quality. During production, by adjusting the number of lid side pieces according to actual needs, custom lids of different sizes and shapes can be achieved. Furthermore, the vertical distribution and chamfered transition connection of the corner lid not only enhance the lid's structural stability but also provide a better seal, preventing the penetration of liquids or fine particles.

[0040] Furthermore, half-side box covers of different shapes or thicknesses can be developed to match box bodies with corresponding structures to meet the storage needs of special shapes or heavy-loaded items.

[0041] In this embodiment, the reinforcing ribs formed by the combination of the main board and the inner concave plate are used to increase the local thickness of the material to improve the bending and torsional resistance of the box cover side pieces. The interaction between the transverse and longitudinal reinforcing ribs forms a strong mesh structure, which helps to disperse and withstand forces from different directions, thereby protecting the items in the box from damage. In order to enhance the mechanical properties of the box cover side pieces, it is ensured that the box cover will not be deformed or damaged when bearing heavy objects or under harsh transportation conditions. The design of the inner concave plate also helps to reduce the use of materials without sacrificing the strength of the structure, thereby improving the overall durability and reliability of the rack box. The presence of the reinforcing ribs enables the box cover side pieces to better withstand and disperse pressure, reducing the risk of damage to items during transportation. This solution significantly improves the load-bearing capacity and overall stability of the box cover through the combination of transverse and longitudinal reinforcing ribs.

[0042] In addition, the inner groove 3 is formed at the junction of the inner concave plate and the side member of the case lid. A latch assembly 31 is located within this groove. The corner case lid is also provided with a groove within which a handle 4 is located. The inner grooves at the junction of the inner concave plate and the case side member accommodate the latch assembly. When the rack case is closed, the latch assembly secures the case lid, ensuring a tight seal between the lid and the case. When the case needs to be opened, the user can operate the latch assembly to release the lid, allowing easy access to the contents. This enhances the practicality and ease of use of the rack case. The inner groove provides a stable position for the latch, ensuring it does not loosen or fall off during use. The latch assembly provides a simple and effective sealing mechanism, preventing the case lid from accidentally opening during transport or storage. The latch assembly prevents the case lid from accidentally opening due to vibration or impact during transport, protecting the contents from damage. Furthermore, the inner groove and latch design enhance the ease of use of the rack case, allowing users to quickly and easily open and close the lid. Furthermore, the internal grooves and latches can be integrated with other intelligent features, such as remote control or status monitoring, to achieve a more advanced rack enclosure management system. By designing grooves in the corner covers of the enclosure and placing handles within these grooves, users have a secure grip when carrying the rack enclosure, effectively reducing the burden on their hands and the risk of finger slippage during handling.

[0043] In summary, the basic structure of the rack box in this embodiment consists of three major components: the box body, the box cover, and the internal support frame. The box body is composed of two halves, with the side walls and bottom plate welded together using hot plate welding technology, ensuring the box's sturdiness and sealing. The box design allows for adjustment of the box's height and volume by adding or removing the number of side components to accommodate objects of varying sizes. The side components include corner covers and an inner concave plate. The corner covers are located at the ends of the box halves and, together with the inner concave plate, form the box's side structure.

[0044] The lid design also adopts a modular concept. The lid side panels are designed to fit tightly with the body side panels, achieving a secure connection through hot plate welding. While maintaining structural strength, the lid's height can be adjusted by adding or removing side panels to accommodate objects of varying heights.

[0045] like Figure 9 As shown, the internal support frame is the core component of the present invention, which is composed of a plurality of beams 6 and is arranged along the edges of the box body and the box cover.

[0046] The internal support frame's beams effectively disperse external impact and pressure, reducing direct damage to the contents. The beams are arranged along the edges of the box, creating a stable internal space structure and ensuring safer contents during transport or storage. This provides a more stable and reliable internal support structure suitable for storing items of varying types and sizes. The support frame reduces movement of contents within the box, preventing damage caused by vibration or impact. This enhances the rack box's ability to protect contents, particularly during transport, significantly reducing the risk of damage. Furthermore, the support frame allows for more efficient planning and utilization of the rack box's internal space. This embodiment utilizes a rectangular cubic frame, with the beams arranged along the edges of the box. This significantly improves the internal stability and protection of the rack box. A shock-absorbing layer is placed between the support frame beams and the box, effectively absorbing and mitigating the effects of external impact, vibration, or pressure on the contents within the box. This cushioning layer helps reduce the risk of damage from bumps, drops, or other external factors during transport. The use of a shock-absorbing layer can significantly reduce damage to objects caused by vibration or impact during transportation, and is especially suitable for objects that are sensitive to vibration or fragile.

[0047] In addition, the internal supports of the rack box are welded and fixed at the corners of the box to form a three-dimensional fulcrum 61, and the frame can be combined with the fixing devices of the items, such as using rubber ropes, foam and other materials to further fix and protect the items. These fixing devices can be customized according to the shape and characteristics of the items to ensure the safety of the items during transportation. In terms of material selection, the rack box of the present invention uses high-strength, wear-resistant materials such as metal, engineering plastics, etc. to enhance the durability of the box. At the same time, the surface of the box can be specially treated, such as spraying an anti-corrosion coating, to improve the performance of the rack box in harsh environments. In terms of the sealing of the rack box, the lock assembly design of the present invention ensures a tight fit between the box cover and the box body. The lock assembly can maintain good sealing performance under different temperature and humidity conditions, prevent the intrusion of moisture and dust, and ensure the safety of the items inside the box.

[0048] Example 2 like Figure 2 As shown, unlike Example 1, the frame beams in this embodiment are formed by interlocking several unit beam segments 9 according to the size of the rack box. The frame beams include a first frame beam 7 extending along the side members of the rack box and a second frame beam 8 extending along the side members of the lid. Both the first and second frame beams consist of unit beam segments of different lengths, and the second frame beam includes the same number of height-adjustable beam segments as the number of lid side members on a single side. By interlocking the unit beam segments, the length and height of the frame beams can be flexibly adjusted to suit the size and shape of the rack box. This design allows the rack box to accommodate objects of varying sizes and shapes, providing a high degree of customizability and adaptability. The design of the first and second frame beams ensures a tight connection between the frame beams and the rack box and lid, providing stable support for the items inside. The use of unit beam segments allows the frame beams' length and height to be easily adjusted to accommodate rack boxes of varying sizes, enabling greater flexibility and diversity in product design. Furthermore, the design of the height-adjustable beam segments 10 allows manufacturers to adjust the frame beam height based on the number of lid side members, further optimizing space utilization and enhancing the adaptability and functionality of the rack box. Manufacturers can select the appropriate rack box size based on their needs and optimize internal space utilization by adjusting the frame beams. This flexibility allows the rack box to be used in a variety of applications, such as logistics, warehousing, and electronic product protection. By utilizing unit beam segments, this solution allows the support frame to be customized to the specific needs of the rack box, enhancing the product's market competitiveness.

[0049] Example 3 like Figure 7 As shown, this embodiment focuses on a minimalist rack box design, which is unique in its structural simplicity and low manufacturing cost. The core concept of this design is to maximize the basic functions of the rack box while simplifying the production process to meet the basic requirements of users with storage space and transportation needs.

[0050] Two prefabricated half-box components, forming the foundation of the rack enclosure, are prepared. Each half-box 22 consists of sidewalls and a bottom plate, and these components are welded together during the manufacturing process. At the beginning of the assembly process, the operator needs to precisely align the corresponding sidewalls of the two halves and ensure that the bottom plates are parallel. Then, welding is performed to connect the sidewalls of the two halves together to form the complete enclosure structure. This welding process requires precision and stability to ensure the enclosure's sealing and structural strength. Next, we will address the enclosure lid. Similar to the enclosure, the enclosure lid also consists of two corner lids 12. The welding of the enclosure lid also requires precision to ensure a tight seal at the top of the rack enclosure.

[0051] In this embodiment, since neither the housing nor the lid includes side pieces, the assembly process is relatively simple, reducing assembly time and operator skill requirements. Furthermore, this rack enclosure design has a minimal thickness, making it particularly useful in space-constrained environments, such as warehousing or transportation, where maximum space utilization is crucial.

[0052] In applications, this type of rack cabinet may be more suitable for the storage or transportation of smaller, lightweight items.

[0053] Example 4 like Figure 1 As shown, in this embodiment, by introducing the box side members 21 and the box cover side members 11, a more flexible and scalable storage solution is provided. The rack box can be adjusted in size by adding or removing the number of side members according to different storage requirements, thereby adapting to more diverse storage needs.

[0054] The process begins with the prefabricated half-box and side pieces. The side pieces are designed to fit snugly against the side walls of the half-box and are typically welded together. During welding, the operator must ensure evenly distributed welds to provide sufficient support and structural stability. After welding, the welds are inspected and tested to ensure there are no cracks or other defects to avoid problems during loading or transport. Next, the lid side pieces are installed. These must be precisely aligned with the two corner lids and the side pieces, secured by welding or fasteners. During this process, the distribution of the lid side pieces is crucial to ensure they can evenly withstand the pressure of the lid while providing a seal to prevent moisture and dust from entering the interior of the box.

[0055] In this embodiment, the introduction of cabinet side members and cabinet cover side members increases the design complexity of the rack cabinet, but also provides more customization options. These side members can be made of different materials, such as high-strength plastic or lightweight alloy, to adapt to different usage environments and cost requirements.

[0056] Example 5 like Figure 8 As shown, this embodiment further expands the flexibility and functionality of the box by adding multiple parallel box side members 21 and box cover side members 11 to achieve greater storage capacity and stronger structural stability. This design is particularly suitable for applications that require transporting or storing large or heavy items.

[0057] The process begins with a preparatory phase, which involves fabricating a series of box halves, sets of box side pieces, and corner and lid side pieces. The box side pieces are designed to be welded together to form a continuous sidewall structure. First, the operator aligns the outermost box side piece with the side wall of the box half and joins them together with precise welding. This step requires particular attention to weld quality to ensure the box sidewall has sufficient strength and stability.

[0058] With the successful installation of the outermost box side pieces, the operator continues to weld the adjacent box side pieces in sequence to form a solid side wall. This process needs to be repeated until all the box side pieces are in place. The interconnection of the box side pieces not only enhances the overall rigidity of the box, but also provides the necessary space for storing large items. In the box lid part, in this embodiment, a design corresponding to the box body is adopted. The operator first arranges multiple box lid side pieces in a predetermined order and ensures that they can be properly aligned with the corner box lids on both sides. Then, the box lid side pieces are fixed to the corner box lids by welding or fasteners to form a sealed and stable box lid structure. This step also requires delicate operation to ensure that the connection between the box lid side pieces is both firm and sealed. The rack box design significantly improves the storage capacity and structural stability by increasing the number of box side pieces, making it an ideal choice for storing and transporting large or heavy items.

[0059] When using a rack box, the user first opens the lid and places the items to be stored or transported into the box according to the pre-defined layout. Because the side panels increase the size of the box, it can accommodate more items or larger individual items. Once loading is complete, the operator closes and secures the lid, ensuring that all lid panels are properly aligned and sealed with the box sides.

[0060] During cabinet manufacturing, welding quality directly impacts the structural stability of the cabinet and lid, so strict quality control must be ensured for all welds. Furthermore, as cabinet sizes increase, more space may be required to store and operate rack cabinets, which may place new demands on storage and transportation environments. Furthermore, users should regularly inspect the cabinet and lid connections during use, especially during frequent use or when loading heavy items, to ensure long-term reliability and durability.

[0061] Furthermore, high-strength engineering plastics or lightweight metals can be used for the box body and lid side members to reduce overall weight without sacrificing strength. Furthermore, welding can be replaced with riveting or bonding to accommodate different production environments or material properties. The value of this design lies in its high adaptability and customizability, enabling it to meet diverse industrial and logistics needs.

[0062] In summary, the rack box design in this embodiment provides an innovative and practical solution for the storage and transportation of large or heavy items through its modularity and scalability.
