Description

Technical Field

[0001] This invention relates to the field of recyclable packaging technology, specifically modular recyclable packaging for electrical materials. Background Technology

[0002] The power industry deals with a wide variety of materials, which are complex in structure, heavy, and have intricate shapes. These materials often come from different sources, some purchased and some manufactured in-house. Previously, each component was individually packaged, requiring numerous wooden crates and cardboard boxes. However, to achieve a single function, multiple crates were often issued, significantly increasing workload in warehousing, transportation, and requisition, resulting in substantial waste. Improvements have been made by packaging the main equipment and its accessories in a single box, reducing workload somewhat. However, this simple consolidation did not reduce overall packaging workload, and material waste persisted. The lack of standardized packaging means that wooden crates from different manufacturers vary in size, and auxiliary equipment is often packaged separately, hindering standardized and unified material management. Assembling empty wooden crates on-site is time-consuming, labor-intensive, and poses safety hazards. If assembly is required from packaging manufacturers, the material coordinator often occupies significant storage space, increasing warehousing costs. Furthermore, the single-use nature of the packaging boxes leads to inconsistent quality and a lack of dimensional accuracy for information-based monitoring, impeding the improvement of supply chain information management.

[0003] Currently, the single-use packaging of electrical equipment results in a significant waste of resources. Taking pole-mounted circuit breakers in Jiangsu Province as an example, the products are generally packaged in wooden crates. When the equipment is packaged individually, the cost per crate is about 200 yuan. According to the latest requirements for complete sets of packaging, the cost per crate is about 300 yuan. The annual usage in Jiangsu Province exceeds 20,000 crates, with an annual packaging cost exceeding 6 million yuan.

[0004] Furthermore, in terms of packaging reliability, common wooden or plastic crates have simple structures and relatively poor reliability. Although some wooden crates use bolts on the bottom plate to fix the equipment, the bolts are often not adjustable or retractable. Empty crates take up a lot of space, cannot be stacked compactly, and safety and reliability decrease with repeated use. If partial damage occurs, they cannot be repaired and must be discarded, which fundamentally hinders the recycling of such crates.

[0005] CN117775414A describes an integrated robot and method for unpacking and sealing samples of wooden crates containing power materials. This also reveals that the packaging, unpacking, and digital management of power materials are urgent issues that need to be addressed in the industry.

[0006] In response to the above situation, developing modular, reusable packaging boxes with reliable internal isolation and protection is of great practical significance. The new packaging boxes can replace the existing wooden and cardboard boxes used for power materials, and can also carry out circular operation management according to equipment transportation needs, effectively promoting the standardization of the power supply chain and improving the level of green development. Summary of the Invention

[0007] To address the technical challenges of modularity and recyclability, this invention presents a modular and recyclable packaging box for electrical materials, the technical solution of which is as follows.

[0008] The electrical equipment includes equipment with bases; the electrical equipment also includes several accessories, several supports, etc.

[0009] Furthermore, the electrical equipment may be a pole-mounted circuit breaker set, the equipment with a grounding foot is the pole-mounted circuit breaker body, and the accessories are a feeder controller and a current transformer, which are respectively packed in an accessory packaging box.

[0010] The packaging box consists of a base, side panels, and a top cover, arranged from bottom to top. The lower surface of the base has nine legs; if these legs interfere with other structures, their position and orientation can be adjusted to avoid interference. The upper surface of the base and the top cover both have grooves that mate with the nine legs. If fixing modules or baffle assemblies arranged on the base interfere with the grooves, their size can be adjusted or they can be hollowed out to avoid interference. The upper surface of the base and the lower surface of the top cover have grooves around their perimeter for inserting side panels. The reverse side of the base has a groove into which reinforcing ribs, which are H-shaped steel frames, are embedded.

[0011] The base, surrounding panels, and top cover are made of plastic. The base can be formed by injection molding, and the fixing modules on it can be formed of plastic or metal materials. It is preferred to use metal parts assembled on the base. Alternatively, metal fixing structures can be pre-embedded during the injection molding process of the base, or in some cases, plastic fixing structures can be directly used and formed with the base in one piece.

[0012] Preferably, when a fixed structure and base are used for assembly, the base has several pre-drilled mounting holes, and bolts are used to fix the structure to the base in the required areas.

[0013] The base has several recessed areas, and each recessed area contains several fixing modules. Each fixing module includes a fixing structure and a fastening structure. The fixing structure is connected to the recessed area and is not higher than the upper surface of the base. The fastening structure can be adjusted to a suitable position on the fixing structure to connect the device's feet to the fixing structure, thereby fixing the device to the base. When not in use, the fastening structure can be flipped and stored inside the fixing structure or removed. After flipping and storing, the highest point of the fastening structure is not higher than the upper surface of the base.

[0014] For a number of accessories or accessory packaging boxes, a baffle module is installed in the sunken area. The baffle module includes a baffle and a hinge. The baffle can be flipped on the base plate with the hinge as the axis to divide into several independent areas for isolating several accessories or accessory packaging boxes. When the baffle is horizontal, the upper surface of the baffle is not higher than the upper surface of the base.

[0015] The baffle has Velcro that attaches to the Velcro on the surrounding panel and / or the baffle has a pin that extends out and engages with the surrounding panel to keep the baffle vertical.

[0016] The recessed area is also equipped with several rotatable pull rings. When in use, the device is erected, a support is placed on the side, and cable ties are used to secure it to the pull rings. When not in use, it is stored horizontally in the recessed area, with the highest point not exceeding the upper surface of the base. Besides securing the support, the pull rings also assist in securing electrical equipment, such as by using cable ties to help bind electrical equipment or by hooking one end of a pressure plate, expanding the versatility of the base. The pull rings can be folded down using a return spring on the shaft, automatically flipping to maintain a horizontal position when not in use, preventing vibration and noise during transportation, and also preventing interference from protruding components when the base is stacked.

[0017] The fastening structure can connect to the mounting holes of the base plate and / or press down on the flange of the base plate to reliably secure the electrical equipment. While connecting the fastening structure to the mounting holes provides a relatively secure fixation, it may increase the workload. It should also be noted that some equipment cannot be fixed when the base plate lacks mounting holes; in such cases, a pressure plate can be used to press down the flange of the base plate, achieving fixation. These two methods can be used in combination, employing both the mounting hole connection and the pressure plate method. Preferably, bolts can be used for the connection to the mounting holes.

[0018] Furthermore, the fixing structure includes a C-shaped component with two side walls and an upward-facing opening. The bottom mounting holes of the C-shaped component are bolted to the base, or the C-shaped component is pre-embedded in the base during its molding. Preferably, there are several mounting holes at the bottom to meet the needs of adjusting the position of the fixing structure.

[0019] In another embodiment, the fixing structure includes two side walls, which are integrally formed at the same time as the base plate.

[0020] Furthermore, the sidewall of the fixing structure is provided with openings, which are a plurality of symmetrical horizontal holes and / or elongated slots. Several sets of horizontal holes are provided to facilitate fine-tuning of the fastening structure on the fixing structure to achieve a suitable position. Preferably, elongated slots are provided to allow for a large and continuous adjustment range of the fastening structure. However, too many elongated slots may reduce the strength of the fixing structure and decrease its reliability. Therefore, combining horizontal holes and elongated slots, along with the adjustable installation position of the fixing structure itself, adapts to the packaging needs of various electrical materials.

[0021] Furthermore, the fastening structure includes a long bolt and a connecting screw. The end of the long bolt has a hole, which is connected to the horizontal hole and / or long slot by the connecting screw. The long bolt can be rotated around the connecting screw as an axis. When in use, the long bolt is vertical and inserted into the mounting hole of the anchor for fixation. The connecting screw is locked in the opening and / or long slot to keep the long bolt vertical.

[0022] When in use, align the long bolt with the connecting hole of the C-shaped channel steel, place a spring washer on each side of the long bolt, insert the connecting screw, and then fix the connecting screw with a nut. After tightening, the long bolt can rotate freely within the fixed structure and has a certain damping, ensuring that the hinge 34 bolt will not tip over when it is perpendicular to the base without interference.

[0023] The lower part of the fixing structure has a spherical protrusion, and the end of the long bolt has a corresponding protrusion. The protrusion of the long bolt is embedded in the spherical protrusion and slides along the length of the fixing structure. Simultaneously, both ends of the fixing structure have openings to accommodate the long bolt, and these openings have removable sealing components. The long bolt can move freely within the fixing structure. After the connecting screw is inserted, it can only rotate around the protrusion and cannot adjust its position. Therefore, it is inconvenient to fix the base of electrical equipment. In normal use, it should first be inserted through the hole at the bottom of the equipment and then the connecting screw should be inserted to fix its position. The spherical protrusion ensures that the hole of the long bolt and the hole or slot on the side wall are aligned, allowing the connecting screw to be blindly inserted. The spherical protrusion does not hinder free rotation and can also achieve positioning. Another effect is that the long bolt will not come out when the connecting screw is disassembled, preventing loss. The long bolt slides into the section of the fixing structure, and using sealing components to plug the ends prevents the long bolt from sliding out from both sides.

[0024] The bottom of the C-shaped component is equipped with a Y-shaped spring, which can deform to clamp or release long bolts. When the long bolts are not in use, the Y-shaped spring clamps the screw without shaking or making abnormal noises, and it also prevents stacking difficulties due to improper storage. It can be easily pulled out from the Y-shaped spring for normal use with a little force.

[0025] Preferably, each of the fixing structures has two fastening structures corresponding to the two mounting holes of the base plate, and the fixing structures are symmetrically arranged according to the number of mounting holes on the base plate. In this case, the fixing structures act as reinforcing ribs. Generally, the fixing structures and fastening structures can correspond one-to-one, or there can be multiple fastening structures on one fixing structure. Preferably, each fixing structure has one fastening structure at each end. This arrangement conforms to the layout characteristics of the base plates of most power equipment. Another advantage is that the fixing structure uses two fastening structures to connect the base plates of the equipment into one unit. The fixing structures can act as reinforcing ribs, greatly increasing the stability of the base and improving reliability.

[0026] To make fastening easier and to be particularly suitable for use in situations where the feet do not have mounting holes, this invention designs another fastening structure, wherein the fastening component includes a pressure plate that presses the feet onto the base for fixation.

[0027] Furthermore, the pressure plate is arc-shaped with holes at both ends, and is connected to the hinge 34 of the long bolt via bolts, allowing the pressure plate to rotate around the bolt. The pressure plate also has a second hole through which a bolt is passed to connect the pressure plate to the fixed structure, with threads or nuts securing it to the bottom of the fixed structure. Using only one long bolt to fix the pressure plate is insufficient to properly restrain it, potentially leading to loosening or rotation. The addition of a second hole, through which the pressure plate is connected to the fixed structure, provides auxiliary fixation to prevent loosening or rotation, increasing reliability.

[0028] Another type of pressure plate has a flat hook 37 at one end, which is used to hang the pressure plate on the pull ring 36 of the base, and a hole or opening at the other end, which is used to fix it to the long bolt of the fixing component by a lock nut. Because of the flat structure, this type of pressure plate will not flip or loosen, so there is no need to configure a second hole 33, and the installation is more convenient.

[0029] For the two types of pressure plates described above, both the bow-shaped and flat-framed types, the long bolts can be either folded within the fixed structure or remain vertically fixed. The vertically fixed bolts do not exceed the upper surface of the base, ensuring that the long bolts do not obstruct stacking after the pressure plate is removed. In this case, the long bolts can be directly fixed to the fixed structure. For the foldable long bolts, their height after falling does not exceed the upper surface of the base. After the pressure plate is removed, the long bolts can be stored within the fixed structure without hindering stacking.

[0030] Another type of pressure plate is a long strip plate with holes. The nut of the fixing structure is a long wedge-shaped block with several threaded holes. The fixing structure has a wedge groove that mates with the wedge block. The wedge groove has a positioning pin and a fixing structure for locking. The bolt passes through the long strip plate and is tightened into the threaded hole to fix the position.

[0031] The two ends of the pressure plate extend to the fixing structure for fixation, and the middle part is used to press down the flange of the foot. Therefore, there are many shapes and methods of pressure plates according to actual needs. The pressure plate can be flat or three-dimensional, and can be flexibly set according to the spatial position of the fixing structure and the flange of the foot.

[0032] Furthermore, the base is equipped with a positioning device. The base has a pre-installed Beidou positioning module mounting box, which can be installed at the bottom of the base. After installation, the sealing cover is lower than the bottom surface of the base to ensure that the positioning equipment is not affected by operation or base deformation during turnover. When installing the positioning equipment, open the bottom positioning module mounting box, place the positioning module inside, fill the surrounding area with sponge or similar breathable non-metallic cushioning material, close the mounting box, and tighten it with screws.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] The modular and recyclable packaging box for this power supply uses modular fixing modules on the base plate. These fixing modules can adapt to the fixed positions of different power supplies, achieving flexible packaging.

[0035] The base features a recessed design for the pre-installed module interfaces, ensuring that all fastening modules can be avoided. The base has no obvious protruding parts and is versatile.

[0036] The fixing module of this invention adopts a flexible fixing structure and a fastening structure. The position of the fixing structure is adjustable, and the position of the fastening structure can also be adjusted on the fixing structure. It is suitable for the cyclic packaging of various power materials. For pole-mounted circuit breakers, because the center of gravity is unstable, they cannot be placed naturally and the bottom needs to be fixed.

[0037] When the fastening structure of the present invention uses a long bolt that can be flipped, it can be reliably connected to the foot of the equipment, and at the same time it can be flipped and stored in the fixed structure without loosening, which is conducive to stacking.

[0038] When the fastening mechanism of the present invention uses a pressure plate, it can be more flexibly matched with the flange of the equipment foot, without cumbersome operation. It is also suitable for situations where the foot does not have bolt holes. It can be removed when not in use without affecting stacking.

[0039] The invention also features a foldable baffle, suitable for partitioned packaging of numerous accessory packages, preventing direct impacts, enabling partitioned storage and protection of materials, increasing packaging reliability, reducing duplicate packaging of accessories, and lowering costs.

[0040] The invention also features a foldable pull ring, which facilitates the binding and securing of internal materials. It can also be used in conjunction with a pressure plate, simplifying the workload of using the pressure plate.

[0041] The packaging box of this invention can be equipped with a positioning device to improve the level of digital management.

[0042] This invention can use plastic to produce the base, enclosure, and cover, and uses metal parts as fixing modules. When used repeatedly, it can be used with various fixing modules to adapt to various types of electrical materials, and the replacement of parts is convenient. Attached Figure Description

Detailed Implementation

[0061] The specific technical solutions of the present invention will be described below with reference to the accompanying drawings. Example

[0062] like Figure 1 The left half is shown; remove it. Figure 1 The baffle 9 and pull ring in this embodiment constitute the base 1 of a modular recyclable packaging box for electrical materials. The electrical materials include equipment with feet 7. The packaging box consists of a base 1, a side panel 2, and a top cover (not shown in the figure) from bottom to top. The base 1 has several recessed areas 3, and several fixing modules 4 are located within the recessed areas 3. Each fixing module 4 includes a fixing structure 5 and a fastening structure 6. The fixing structure 5 is connected to the recessed areas 3 and is not higher than the upper surface of the base 1. The fastening structure 6 can be adjusted to a suitable position on the fixing structure 5 to connect the feet 7 of the equipment to the fixing structure 5, thereby fixing the equipment to the base 1. When not in use, the fastening structure 6 can be flipped and stored inside the fixing structure 5 or removed. After flipping and storing, the highest point of the fastening structure 6 is not higher than the upper surface of the base 1. Example

[0063] like Figure 1 As shown, remove Figure 1The pull ring in this embodiment is the base plate of a modular recyclable packaging box for electrical materials. The difference from Embodiment 1 is that, in addition to the equipment with feet 7, the electrical materials also include several accessories. Therefore, based on the technical solution of Embodiment 1, it also includes the following structure: a baffle module 8 is installed in the sunken area 3. The baffle module 8 includes a baffle 9 and a hinge 10. The baffle 9 can be flipped on the base plate around the hinge 10 to divide it into several independent areas for isolating several accessories. When the baffle 9 is horizontal, its upper surface is not higher than the upper surface of the base 1. The baffle 9 has Velcro 14 that is attached to the Velcro 14 on the surrounding panel 2, and / or the baffle 9 has a pin that extends and engages with the surrounding panel 2 to keep the baffle 9 vertical. Example

[0064] like Figure 1 As shown, the difference from Embodiment 2 is that, in addition to the equipment with feet 7 and several accessories, the power supplies also include several supports 18. Therefore, pull rings are added based on Embodiment 2. The sunken area 3 is also provided with several flip-up pull rings. When in use, the equipment is erected, and the supports 18 are placed on the side of the equipment and fixed to the pull rings with cable ties 38. When not in use, the equipment is stored horizontally in the sunken area 3, with the highest point not exceeding the upper surface of the base 1. The supports 18 can be placed on the back of the equipment with feet 7 and then secured to the pull rings with cable ties 38. Example

[0065] like Figure 2 As shown, a modular recyclable packaging box for a pole-mounted circuit breaker kit is provided. The pole-mounted circuit breaker kit includes a pole-mounted circuit breaker body 15, a feeder controller 16, a current transformer 17, and a bracket 18. The feeder controller 16 and current transformer 17 are respectively packed in the accessory package 19, and the bracket 18 is placed on one side.

[0066] The packaging box consists of a base 1, a side panel 2, and a top cover (not shown in the figure) from bottom to top. The base 1 has several recessed areas 3, and each recessed area 3 contains several fixing modules 4. Each fixing module 4 includes a fixing structure 5 and a fastening structure 6. The fixing structure 5 is connected to the recessed areas 3 and is not higher than the upper surface of the base 1. The fastening structure 6 can be adjusted to a suitable position on the fixing structure 5 and connects to the mounting holes 20 of the pole-mounted circuit breaker body 15, thus connecting the pole-mounted circuit breaker body 15 to the fixing structure 5 and fixing it to the base 1. When not in use, the fastening structure 6 can be flipped and stored inside the fixing structure 5 or removed. After flipping and storing, the highest point of the fastening structure 6 is not higher than the upper surface of the base 1. The sunken area 3 is equipped with a baffle module 8, which includes a baffle 9 and a hinge 10. The baffle 9 can be flipped around the base plate with the hinge 10 as the axis to divide it into several independent areas for storing the packaging boxes of the feeder controller 16 and the current transformer 17. When the baffle 9 is horizontal, its upper surface is not higher than the upper surface of the base 1. The baffle 9 has Velcro 14, which is attached to the Velcro 14 on the surrounding plate 2, and / or the baffle 9 has a pin that extends out and locks onto the surrounding plate 2 to keep the baffle 9 vertical. The sunken area 3 is also equipped with several flip-up pull rings. When in use, the baffle is erected, a bracket 18 is placed on the side of the equipment, and the rings are fixed with cable ties 38. When not in use, the baffle is stored horizontally in the sunken area 3, with the highest point not higher than the upper surface of the base 1. Example

[0067] like Figure 3 As shown, similar to Embodiment 4, a modular recyclable packaging box for a pole-mounted circuit breaker kit is provided. The kit includes a pole-mounted circuit breaker body 15, a feeder controller 16, a current transformer 17, and a bracket 18, with the bracket 18 placed on one side. The difference is that the accessories, feeder controller 16 and current transformer 17, do not have a packaging box and are directly fixed to the floor. The packaging design is as follows:

[0068] The packaging box consists of a base 1, a side panel 2, and a top cover (not shown in the figure) from bottom to top. The base 1 has several recessed areas 3, and each recessed area 3 contains several fixing modules 4. Each fixing module 4 includes a fixing structure 5 and a fastening structure 6. The fixing structure 5 is connected to the recessed areas 3 and is not higher than the upper surface of the base 1. The fastening structure 6 can be adjusted to a suitable position on the fixing structure 5 and connects to the mounting holes 20 of the pole-mounted circuit breaker body 15 and the current transformer 17, thus connecting the pole-mounted circuit breaker body 15 and the current transformer 17 to the fixing structure 5 and fixing them to the base 1. The pole-mounted circuit breaker body 15 has three sets of structures, and the current transformer 17 has two sets of structures, which are nested together to save space. When not in use, the fastening structure 6 can be flipped and stored inside the fixing structure 5 or removed. After flipping and storing, the highest point of the fastening structure 6 is not higher than the upper surface of the base 1. The base 1 is provided with a groove 13 that has the same shape as the bottom of the feeder controller 16. The base 1 of the feeder controller 16 falls into the groove 13 and is placed next to the current transformer 17. If necessary, it is secured with a pull ring. Example

[0069] like Figure 4 As shown, the fixing structure 5 and fastening structure 6 in the above embodiments 1-5 can be selected from the fixing module 4 in this embodiment.

[0070] The fixing structure 5 includes a C-shaped component 21 with its opening facing upwards. The bottom mounting hole 22 of the C-shaped component is bolted to the base 1. Several mounting holes are provided to allow adjustment of the position of the C-shaped component 21. The side wall 23 of the fixing structure 5 has openings, which are several symmetrical horizontal holes 27. The fastening structure 6 includes a long bolt 24 and a connecting screw 25. The end of the long bolt 24 has a hole 26, which is connected to the horizontal hole 27 by the connecting screw 25. The long bolt 24 can rotate around the connecting screw 25. In use, the long bolt 24 is vertical and inserted into the mounting hole 20 for fixation. The connecting screw 25 is locked in the horizontal hole 27 to keep the long bolt 24 vertical.

[0071] The connecting screw 25 has spring washers 28 and nuts 29 on both sides. The long bolt 24 is aligned with the horizontal hole 27 of the C-shaped part 21. A spring washer 28 is placed on each side of the long bolt 24 and inserted into the connecting screw 25. Then the connecting screw 25 is fixed with nuts 29. After tightening, the long bolt 24 can rotate freely in the C-shaped part 21 and has a certain damping, ensuring that the hinge bolt will not overturn when it is perpendicular to the base 1 without interference.

[0072] The bottom of the C-shaped component 21 is provided with a Y-shaped spring, which can deform to clamp or release the long bolt 24. Example

[0073] like Figure 5 As shown. Unlike the fixing structure 5 in Embodiment 6, the side wall 23 of the fixing structure 5 is provided with an opening, which is either a symmetrical elongated groove 30 or a combination of a horizontal hole 27 and an elongated groove 30. In this way, the connecting screw 25 of the fastening structure 6 can slide within the elongated groove 30 to adjust its position, and can also be locked by the nut 29. Example

[0074] Unlike Embodiment 6, the C-shaped part 21 is pre-embedded in the base 1 during the molding of the base 1, and does not require mounting holes at the bottom to be installed on the base plate. Example

[0075] like Figure 6 As shown, unlike Embodiment 6, the fixing structure 5 includes two side walls 23, which are integrally formed during the forming of the base plate. The side walls 23 of the fixing structure 5 are provided with openings, which are symmetrical and / or elongated grooves 30.

[0076] The fastening structure 6 is the same as that in embodiments 1 to 6. The fastening structure 6 includes a long bolt 24 and a connecting screw 25. The end of the long bolt 24 has a hole 26 and is connected to the long groove 30 by the connecting screw 25. The long bolt 24 can rotate around the connecting screw 25. When in use, the long bolt 24 is vertical and inserted into the anchor mounting hole 20 for fixation. The connecting screw 25 is locked in the long groove 30 to keep the long bolt 24 vertical. Example

[0077] like Figure 17 As shown, the difference from embodiments 7, 8, and 9 is that the lower part of the fixing structure 5 has a spherical protrusion 43, and the end of the long bolt 24 has a protrusion that matches it. The protrusion of the long bolt 24 is fitted into the spherical protrusion 43 and slides along the length direction of the fixing structure 5. At the same time, both ends of the fixing structure 5 have openings that can accommodate the long bolt 24 to enter, and the openings have removable sealing parts.

[0078] The long bolt 24 can move freely within the fixed structure 5. After the connecting screw 25 is inserted, it can only rotate around it and cannot be adjusted in position. Therefore, it is inconvenient to fix the base 1 of electrical equipment. During normal use, it should first pass through the hole in the bottom foot of the equipment, and then be inserted into the connecting screw 25 to fix its position. The spherical protrusion 44 ensures that the hole 26 of the long bolt 24 and the horizontal hole 27 or long groove 30 of the side wall 23 are aligned, allowing the connecting screw 25 to be blindly inserted. The spherical protrusion 44 does not hinder free rotation and can also achieve positioning. Another effect is that the long bolt 24 will not come out when the connecting screw 25 is disassembled, preventing loss. The long bolt 24 slides into the section of the fixed structure 5; using a sealing piece to plug the end can prevent the long bolt 24 from sliding out from both sides. Example

[0079] like Figure 7-14 As shown, the fastening structure 6 in the aforementioned embodiments can all be replaced with the form of this embodiment. The fastening structure 6 can press down the flange of the foot 7. The fastening assembly includes a pressure plate 31, which presses the foot 7 onto the base 1 for fixation. Both ends of the pressure plate 31 extend to the fixing structure 5 for fixation, and the middle part is used to press down the flange of the foot 7. Therefore, there are many shapes and methods of the pressure plate 31 according to actual needs. The pressure plate 31 can be flat or three-dimensional, and can be flexibly set according to the spatial position of the fixing structure 5 and the flange of the foot 7.

[0080] like Figure 7 , 8 As shown in Figures 9 and 10, the pressure plate 31 is arc-shaped, with holes at both ends. It is connected to the hinge of the long bolt 24 via bolts 32, allowing the pressure plate 31 to rotate around the bolts 32. The pressure plate 31 also has a second hole through which a bolt is passed to connect it to the fixing structure 5. The bolt is then threaded or secured to the bottom of the fixing structure 5. Using only one long bolt 24 to fix the pressure plate 31 is insufficient to properly restrain it, potentially leading to loosening or rotation. The addition of a second hole, with a bolt 35 inside, connects the pressure plate 31 to the fixing structure 5, providing auxiliary fixation to prevent loosening or rotation and increasing reliability. Example

[0081] like Figure 11 , 12 As shown in Figure 13, unlike Embodiment 11, another type of pressure plate 31 has a flat hook at one end, which is hung on the pull ring of the base 1, and a hole or opening at the other end, which is fixed to the long bolt 24 of the fixing component by locking bolt 32. Because of the flat structure, this type of pressure plate 31 will not flip or loosen, so there is no need to configure a second hole, and the installation is more convenient.

[0082] In both the bow-shaped and flat-structured pressure plates 31, the long bolts 24 can either be rotated within the fixed structure 5 or remain vertically fixed. The height of the vertically fixed bolts 24 does not exceed the upper surface of the base 1, so that after the pressure plate 31 is removed, the long bolts 24 do not obstruct stacking. In this case, the long bolts 24 can be directly fixed to the fixed structure 5. The rotating long bolts 24, after falling, do not exceed the upper surface of the base 1. After the pressure plate 31 is removed, the long bolts 24 can be stored within the fixed structure 5 without obstructing stacking.

[0083] like Figure 14As shown, there is another type of pressure plate 31, which is a long strip plate with holes. The nut of the fixing structure 5 is a long wedge-shaped block with several threaded holes. The fixing structure 5 has a wedge groove 39 that mates with the wedge block 40. The wedge groove 39 has a positioning pin and is locked to the fixing structure 5. The bolt passes through the long strip plate and is tightened in the threaded hole to fix the position. Example

[0084] like Figure 16 As shown, unlike other embodiments, the base 1 is equipped with a positioning device in addition to the above-described scheme. The base 1 has a pre-installed mounting box for the Beidou positioning module 41, which can be installed at the bottom of the base 1. After installation, the sealing cover is lower than the bottom surface of the base 1 to ensure that the positioning device is not affected by operation or deformation of the base 1 during turnover. When installing the positioning device, open the bottom mounting box for the positioning module 41, place the positioning module 41 inside, fill the surrounding area with sponge or similar breathable non-metallic cushioning material, close the mounting box, and secure it with screws. Example

[0085] Further optimizations were made to the technical solutions of Embodiments 5 and 6. The fixing structure 5 and fastening structure 6 in Embodiment 6 were applied to Embodiment 5. At the same time, each fixing structure 5 has two fastening structures 6, corresponding to the two mounting holes of the foot 7. According to the specific problems of the pole-mounted circuit breaker assembly, the circuit breaker body 15 has four feet 7, the current transformer 17 also has four feet 7, while the feeder controller 16 has no feet 7, and the bracket 18 is placed on one side.

[0086] like Figure 15 As shown, two sets of long fixing structures 5 correspond to the circuit breaker body 15, and two sets of short fixing structures 5 correspond to the current transformer 17. The mounting holes 20 are symmetrically arranged with fastening structures 6. The fixing structure 5 between the two fastening structures 6 is located on the floor, at the bottom of the equipment, serving as a reinforcing rib. Example

[0087] like Figure 1 , 2 As shown in Figures 3, 15, and 16, the lower surface of the base 1 has nine legs 12, and the upper surface of the base 1 and the top cover both have nine-legged grooves 11 that match the nine legs 12; the upper surface of the base 1 and the lower surface of the top cover have grooves around which the surrounding plates 2 are inserted; the reverse side of the base 1 has a groove in which reinforcing ribs are embedded and installed, and the reinforcing ribs are H-shaped steel frames. The base 1, the surrounding plates 2, and the top cover are made of plastic, while the fixing structure 5 and the fastening structure 6 are made of metal.

[0088] After testing, the basic structure of base 1 was customized by mold opening. The base of base 1 is made of high-density polyethylene or plastic with a strength not lower than high-density polyethylene to meet the load-bearing requirements. The production process can be blow molding, vacuum forming, injection molding and other processes. The interface of fixed module 4 is reserved. Fixed module 4, H-beam 42 frame and positioning device are uniformly added, adjusted and replaced according to work requirements.

[0089] The base 1 is equipped with a positioning device. The base 1 has a reserved mounting box for the Beidou positioning module 41, which can be installed at the bottom of the base 1. After installation, the sealing cover is lower than the bottom surface of the base 1 to ensure that the positioning device is not affected by operation or deformation of the base 1 during turnover. When installing the positioning device, open the bottom positioning module 41 mounting box, place the positioning module 41 inside, fill the surrounding area with sponge or similar breathable non-metallic cushioning material, close the mounting box, and tighten it with screws.

[0090] The method for using the modular packaging box for pole-mounted circuit breakers is as follows: Before packaging, adjust the positions of the fixing structure 5 and fastening structure 6 on the base 1 so that the mounting holes on the base 1 of the pole-mounted circuit breaker body 15 are aligned with the position of the fastening structure 6. Then, lock the pole-mounted circuit breaker body 15 onto the base plate. Fold the baffle 9 vertically and fix it. Place the feeder controller 16 and the current transformer 17 in the area divided by the baffle 9. The pull ring can be used for binding and fixing. Place the iron accessories on one side of the pole-mounted circuit breaker body 15 and fix them to the pull ring with cable ties 38. Put the enclosure 2 into the groove 13 on the base plate and then fasten the top plate to complete the packaging. Loosen the fastening structure 6 and cable ties 38 to take out the goods. After taking out the goods, flip the fastening structure 6 and store it inside the fixing structure 5. The highest point of the fastening structure 6 should not be higher than the upper surface of the base 1. Flip the baffle 9 and pull ring, fold the enclosure 2, and stack the base 1 and cover plate for storage. Adjust the orientation and size of the four corners of the nine-legged 12 to avoid the reserved slots of the fixed module 4 and H-beam 42. After adjustment, ensure that the supporting steel frame and fixed module 4 can meet the working requirements, do not interfere with the nine-legged 12, and do not affect the recycling and stacking.
