Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of ultra-thin corrugated paper and ultra-thin corrugated paper boxes, in particular to an ultra-thin corrugated paper box structure based on ultra-thin corrugated paper. BACKGROUND

[0002] Corrugated paper is mainly composed of a face paper layer and a corrugated core in a wave shape, which is compounded by an adhesive process. The unique wave structure can effectively disperse impact force, and is widely used in the packaging field to make corrugated paper boxes for shipping goods, providing protection against collision and extrusion during transportation. In order to reduce the weight of the corrugated paper box and improve the transportation convenience of the goods, an ultra-thin corrugated paper (the thickness of the face paper layer is between 0.2mm and 0.3mm) is generally used to manufacture an ultra-thin corrugated paper box. However, due to the thin thickness of the face paper layer of the ultra-thin corrugated paper box, the structural strength of the ultra-thin corrugated paper box is low, and thus it is easy to be damaged by extrusion deformation during stacking, storage or transportation. At the same time, when the ultra-thin corrugated paper box is directly placed on the ground, the ground moisture gas easily penetrates into the paper box. Especially in humid areas, the corrugated paper becomes soft due to excessive moisture absorption, resulting in a significant decrease in the structural strength of the paper box, which not only cannot effectively protect the internal goods, but also allows the humid gas to further penetrate into the box, affecting the quality of the goods.

[0003] To solve the above problems, some manufacturers have made further research and development. For example, the existing technology patent CN217865368U proposes a paper box with an anti-falling structure, which discloses a paper box body, which is a three-layer composite corrugated paper box. When transporting high-value goods, a protective box is sleeved outside the paper box body, and a second buffer layer supported by a grid support is arranged between the protective box and the paper box body, so that external impact can be greatly buffered, thereby protecting the internal goods. A lower corner is arranged at the lower side of each corner of the protective box, and a first buffer layer is arranged between the lower corner and the protective box, which can prevent the bottom corner from deforming when falling. The bottom corner of the protective box is provided with a recessed accommodation groove, and the lower corner is arranged on the inner wall of the accommodation groove, so that the lower corner can maintain a certain thickness to improve the protection effect, and at the same time prevent the ground moisture gas from penetrating into the corrugated paper.

[0004] However, the above anti-falling structure has poor limiting effect on the corrugated paper box. Due to external factors such as vibration or collision during transportation, the paper box is easy to come off from the protective box, which greatly increases the risk of damage to the corrugated paper box and the goods, thereby greatly reducing the safe delivery rate of the goods. SUMMARY

[0024] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in conjunction with specific embodiments: As Figures 1 to 9As shown, the ultra-thin corrugated paper box structure 10 of one embodiment based on ultra-thin corrugated paper includes an ultra-thin corrugated paper box 100 and a plastic shell protection assembly 200; the plastic shell protection assembly 200 is formed with a mounting limiting groove 210, the mounting limiting groove 210 is used to accommodate the limiting ultra-thin corrugated paper box 100, the inner circumferential wall of the mounting limiting groove 210 is fixed with a toothed limiting piece 300, the toothed limiting piece 300 is used to abut and partially embed in the surface paper layer 110 of the ultra-thin corrugated paper box 100 when the plastic shell protection assembly 200 limits the ultra-thin corrugated paper box 100, not only can the toothed limiting piece 300 form mechanical engagement with the ultra-thin corrugated paper box 100, but also the toothed limiting piece 300 can concentrate external force to a small area to form a high pressure area, thereby greatly improving the friction between the toothed limiting piece 300 and the ultra-thin corrugated paper box 100, compared with the paper box with the anti-falling structure in the above related technology, the plastic shell protection assembly 200 of the present disclosure can firmly limit the ultra-thin corrugated paper box 100 through the toothed limiting piece 300, effectively reducing the possibility of the ultra-thin corrugated paper box 100 from the mounting limiting groove 210 due to external factors such as vibration or collision during transportation, so that the plastic shell protection assembly 200 can effectively protect the ultra-thin corrugated paper box 100 and the goods in the mounting limiting groove 210, greatly reducing the risk of damage to the ultra-thin corrugated paper box 100 and the goods, thereby greatly improving the safe delivery rate of the goods.

[0025] The above-mentioned ultra-thin corrugated paper box structure 10 based on ultra-thin corrugated paper, because the plastic shell protection assembly 200 is formed with a mounting limiting groove 210, the mounting limiting groove 210 is used to accommodate the limiting ultra-thin corrugated paper box 100, the inner circumferential wall of the mounting limiting groove 210 is fixed with a toothed limiting piece 300, the toothed limiting piece 300 is used to abut and partially embed in the surface paper layer 110 of the ultra-thin corrugated paper box 100 when the plastic shell protection assembly 200 limits the ultra-thin corrugated paper box 100, not only can the toothed limiting piece 300 form mechanical engagement with the ultra-thin corrugated paper box 100, but also the toothed limiting piece 300 can concentrate external force to a small area to form a high pressure area, thereby greatly improving the friction between the toothed limiting piece 300 and the ultra-thin corrugated paper box 100, compared with the paper box with the anti-falling structure in the above related technology, the plastic shell protection assembly 200 of the present disclosure can firmly limit the ultra-thin corrugated paper box 100 through the toothed limiting piece 300, effectively reducing the possibility of the ultra-thin corrugated paper box 100 from the mounting limiting groove 210 due to external factors such as vibration or collision during transportation, so that the plastic shell protection assembly 200 can effectively protect the ultra-thin corrugated paper box 100 and the goods in the mounting limiting groove 210, greatly reducing the risk of damage to the ultra-thin corrugated paper box 100 and the goods, thereby greatly improving the safe delivery rate of the goods.

[0026] As Figures 1 to 5As shown, in one of the embodiments, the plastic shell protection assembly 200 comprises a support bottom plate 220 and a plurality of support side plates 230, the plurality of support side plates 230 are arranged around the outer periphery of the support bottom plate 220, each support side plate 230 is connected with the support bottom plate 220, and the two side edges of each support side plate 230 are respectively supported and abutted with the side edges of the adjacent two support side plates 230, so that the support bottom plate 220 and the support side plates 230 jointly form the mounting limiting groove 210, thereby improving the structural strength of the plastic shell protection assembly 200, so that the plastic shell protection assembly 200 can effectively protect the ultra-thin corrugated paper box 100; the side surface of each support side plate 230 towards the mounting limiting groove 210 is fixed with at least one tooth-shaped limiting piece 300, each tooth-shaped limiting piece 300 abuts and is partially embedded in the face paper layer 110 of the ultra-thin corrugated paper box 100, so that the ultra-thin corrugated paper box 100 can be more firmly limited in the mounting limiting groove 210, effectively reducing the possibility of the ultra-thin corrugated paper box 100 being affected by external factors such as vibration or collision in the transportation process and being separated from the mounting limiting groove 210, so that the plastic shell protection assembly 200 can effectively protect the ultra-thin corrugated paper box 100 and the goods in the mounting limiting groove 210, greatly reducing the risk of damage to the ultra-thin corrugated paper box 100 and the goods, thereby greatly improving the safe delivery rate of the goods, further reducing the risk of damage to the ultra-thin corrugated paper box 100 and the goods, thereby greatly improving the safe delivery rate of the goods.

[0027] As shown in the embodiment, Figures 1 to 5 In one embodiment, each tooth-shaped limiting piece 300 on each support side plate 230 is arranged in parallel and spaced apart, so that the plastic shell protection assembly 200 can be more firmly limited in the mounting limiting groove 210, effectively reducing the possibility of the ultra-thin corrugated paper box 100 being affected by external factors such as vibration or collision in the transportation process and being separated from the mounting limiting groove 210, so that the plastic shell protection assembly 200 can effectively protect the ultra-thin corrugated paper box 100 and the goods in the mounting limiting groove 210.

[0028] As shown in the embodiment, Figures 1 to 3 In one embodiment, the support bottom plate 220 is a PVC bottom plate, an acrylic bottom plate or an epoxy resin bottom plate, which not only enables the support bottom plate 220 to have better structural strength and moisture-proof effect, but also has a lower weight.

[0029] As shown in the embodiment, Figures 1 to 3 In one embodiment, the support side plate 230 is a PVC bottom plate, an acrylic bottom plate or an epoxy resin bottom plate, which not only enables the support side plate 230 to have better structural strength and moisture-proof effect, but also has a lower weight.

[0030] As shown in the embodiment, Figures 1 to 5As shown, it can be understood that, since the inner part of the installation limiting groove 210 is fixed to the tooth-shaped limiting part 300, when it is needed to place the ultra-thin corrugated paper box 100 in the installation limiting groove 210 or take the ultra-thin corrugated paper box 100 out of the installation limiting groove 210, the tooth-shaped limiting part 300 will not only hinder the ultra-thin corrugated paper box 100, but also easily scratch or even cut the ultra-thin corrugated paper box 100, so that the installation and dismounting difficulty of the ultra-thin corrugated paper box 100 is greatly increased.

[0031] As shown in the drawings, Figures 1 to 5 In one embodiment, each support side plate 230 is rotationally connected with the support bottom plate 220, and the plastic shell protection assembly 200 further comprises a bundling part 240, which is used to bundle the support side plate 230 when the tooth-shaped limiting part 300 of each support side plate 230 abuts against the ultra-thin corrugated paper box 100. The bundling part 240 is wound around one side of each support side plate 230 away from the tooth-shaped limiting part 300 and wound at least one turn, so that when it is needed to place the ultra-thin corrugated paper box 100 in the installation limiting groove 210, it is only needed to first place the ultra-thin corrugated paper box 100 at a preset position of the support bottom plate 220, then rotate each support side plate 230 towards the ultra-thin corrugated paper box 100 until the tooth-shaped limiting part 300 of each support side plate 230 abuts against and is partially embedded in the face paper layer 110 of the ultra-thin corrugated paper box 100, and finally wind the bundling part 240 around one side of each support side plate 230 away from the tooth-shaped limiting part 300, so that the support side plate 230 and the support bottom plate 220 can jointly form the installation limiting groove 210 to limit the ultra-thin corrugated paper box 100; when it is needed to take the ultra-thin corrugated paper box 100 out of the installation limiting groove 210, it is only needed to first take out the bundling part 240, then rotate each support side plate 230 away from the ultra-thin corrugated paper box 100 until the tooth-shaped limiting part 300 of each support side plate 230 is separated from the face paper layer 110 of the ultra-thin corrugated paper box 100, and finally take the ultra-thin corrugated paper box 100 out of the support bottom plate 220, which not only effectively reduces the possibility that the ultra-thin corrugated paper box 100 is separated from the installation limiting groove 210 due to external factors such as vibration or collision during transportation, but also avoids the phenomenon that the tooth-shaped limiting part 300 scratches or even damages the ultra-thin corrugated paper box 100, thereby greatly reducing the installation and dismounting difficulty of the ultra-thin corrugated paper box 100 and improving the use convenience of the plastic shell protection assembly 200.

[0032] As shown in the drawings, Figures 3 to 4 In one embodiment, the support bottom plate 220 is provided with a first reinforcing rib 221 to improve the structural strength of the support bottom plate 220. Further, the support bottom plate 220 and the first reinforcing rib 221 are an integrally formed structure to improve the structural compactness of the support bottom plate 220 and the first reinforcing rib 221.

[0033] AsFigures 3 to 4 As shown, in one embodiment, each supporting side plate 230 is provided with a second reinforcing rib 231 to improve the structural strength of the supporting side plate 230. Furthermore, each supporting side plate 230 and its corresponding second reinforcing rib 231 are integrally formed to improve the structural compactness of the supporting side plate 230.

[0034] like Figures 1 to 4 As shown, in one embodiment, the plastic shell protection assembly 200 further includes a pivot member 250. The two ends of the pivot member are connected to a supporting base plate 220 and a supporting side plate 230, respectively. The supporting side plate 230 is rotatably connected to the supporting base plate 220 via the pivot member 250, allowing the supporting side plate 230 to rotate relative to the supporting base plate 220 via the pivot member 250. This allows the supporting side plate 230 to rotate relative to the supporting base plate 220 towards the ultra-thin corrugated cardboard box 100 when the ultra-thin corrugated cardboard box 100 needs to be installed in the mounting limiting groove 210, until the toothed limiting member 300 of the supporting side plate 230 abuts against and partially embeds into the face paper layer 110 of the ultra-thin corrugated cardboard box 100. This allows the supporting side plate 230 to form an installation limiting groove 210 together with the supporting base plate 220, thereby ensuring that the ultra-thin corrugated cardboard box 100 is securely positioned within the installation limiting groove 210. When the ultra-thin corrugated cardboard box 100 needs to be removed from the installation limiting groove 210, the supporting side plate 230 can rotate relative to the supporting base plate 220 away from the ultra-thin corrugated cardboard box 100 via the pivot member 250, allowing the toothed limiting member 300 to disengage from the face paper layer 110 of the ultra-thin corrugated cardboard box 100 and move away from the ultra-thin corrugated cardboard box 100. This greatly reduces the difficulty of installing and disassembling the ultra-thin corrugated cardboard box 100, thereby significantly improving the ease of use of the ultra-thin corrugated cardboard box structure 10 based on ultra-thin corrugated paper.

[0035] like Figures 1 to 4 As shown, in one embodiment, there are multiple pivot members 250, and at least one pivot member 250 is provided between each support side plate 230 and the support base plate 220, so that each support side plate 230 can rotate relative to the support base plate 220, thereby greatly reducing the difficulty of installing and disassembling the ultra-thin corrugated cardboard box 100.

[0036] like Figures 1 to 4 As shown, in one embodiment, the pivot member 250 includes a rotating shaft 251 and two connecting parts 252. The two connecting parts 252 are respectively fixed to the fixed end and the rotating end of the rotating shaft 251, and the two connecting parts 252 are respectively connected to the supporting base plate 220 and the supporting side plate 230. The supporting side plate 230 is rotatably connected to the supporting base plate 220 through the rotating shaft 251.

[0037] like Figures 1 to 3As shown in the drawings, in one embodiment, the two connecting portions 252 are respectively a first connecting portion 2521 and a second connecting portion 2522, the first connecting portion 2521 is detachably connected with the support bottom plate 220, and the second connecting portion 2522 is detachably connected with the support side plate 230, so as to facilitate the mounting and dismounting of the pivot piece 250, the support bottom plate 220 and the support side plate 230, so that the difficulty of replacement and maintenance of the pivot piece 250, the support bottom plate 220 and the support side plate 230 is greatly reduced, and the maintenance cost and production cost of the plastic shell protection assembly 200 are greatly reduced.

[0038] As shown in the drawings, Figures 1 to 3 As shown in the drawings, in one embodiment, the plastic shell protection assembly 200 further comprises a first fastener (not shown in the drawings), the first connecting portion 2521 is formed with a first positioning hole 25211, the support bottom plate 220 is formed with a first threaded hole 222 which is oppositely arranged with the first positioning hole 25211, and the first fastener passes through the first positioning hole 25211 and is screwed into the first threaded hole 222, so as to not only enable the first connecting portion 2521 to be firmly fixed on the support bottom plate 220, but also further reduce the difficulty of mounting and dismounting of the pivot piece 250 and the support bottom plate 220, so as to facilitate the maintenance and replacement and production assembly of the support bottom plate 220, and thus greatly improve the use stability and convenience of the plastic shell protection assembly 200.

[0039] As shown in the drawings, Figures 1 to 3 As shown in the drawings, in one embodiment, the plastic shell protection assembly 200 further comprises a second fastener (not shown in the drawings), the second connecting portion 2522 is formed with a second positioning hole 25221, the support side plate 230 is formed with a second threaded hole 232 which is oppositely arranged with the second positioning hole 25221, and the second fastener passes through the second positioning hole 25221 and is screwed into the second threaded hole 232, so as to not only enable the second connecting portion 2522 to be firmly fixed on the support side plate 230, but also further reduce the difficulty of mounting and dismounting of the pivot piece 250 and the support side plate 230, so as to facilitate the maintenance and replacement and production assembly of the support side plate 230, and thus greatly improve the use stability and convenience of the plastic shell protection assembly 200.

[0040] It can be understood that most of the rotating shafts 251 on the market at present are metal components, and when the plastic shell protection assembly 200 is in a humid environment for a long time, the metal inside the rotating shaft 251 is prone to rust, which causes the support side plate 230 to be prone to jamming when rotating relative to the support bottom plate 220, so that the pivot piece 250 needs to be positioned, maintained and replaced, which not only greatly reduces the use stability of the plastic shell protection assembly 200, but also greatly increases the maintenance cost of the plastic shell protection assembly 200.

[0041] As shown in the drawings, Figure 1As shown in the figure, in another embodiment, the pivot joint 250 can also be a flexible soft rubber, and the two ends of the flexible soft rubber are fixed to the support bottom plate 220 and the support side plate 230 respectively, so that the support side plate 230 can rotate relative to the support bottom plate 220 through the elastic performance of the flexible soft rubber. Compared with the structure of the pivot shaft 251, the flexible soft rubber can not only have a longer service life in a humid environment, but also effectively avoid the phenomenon of the pivot joint 250 being stuck, so as to ensure that the plastic shell protection assembly 200 can maintain stable and normal work for a long time, thereby greatly improving the use stability and maintenance cost of the plastic shell protection assembly 200.

[0042] As shown in the figure, Figure 1 in another embodiment, the two ends of the flexible soft rubber are fixed to the support bottom plate 220 and the support side plate 230 by secondary injection molding, so that the two ends of the pivot joint 250 can be firmly fixed to the support bottom plate 220 and the support side plate 230 respectively, so as to ensure that the plastic shell protection assembly 200 works stably, thereby greatly improving the use stability of the plastic shell protection assembly 200.

[0043] As shown in the figure, Figure 1 in another embodiment, the flexible soft rubber is flexible silicone, thermoplastic elastomer, thermoplastic polyurethane or soft PVC, so that the pivot joint 250 can have better elastic performance and corrosion resistance.

[0044] As shown in the figure, Figures 1 to 5 in one of the embodiments, the plastic shell protection assembly 200 further comprises a limiting sleeve 260, and each support side plate 230 is fixed with a limiting sleeve 260 on the side away from the tooth-shaped limiting flange, and each limiting sleeve 260 is located on the same horizontal plane. The binding member 240 is sequentially provided in the limiting sleeve 260, and is wound on one side of each support side plate 230 away from the tooth-shaped limiting member 300, so that the limiting sleeve 260 can limit the binding member 240 at the preset position of the plastic shell protection assembly 200, avoiding the phenomenon that the binding member 240 slides relative to the support side plate 230, so that the binding member 240 can limit each support side plate 230 at the preset position of the ultra-thin corrugated paper box 100, ensuring that each tooth-shaped limiting member 300 maintains the state of abutting and partially embedding into the face paper layer 110 of the ultra-thin corrugated paper box 100, thereby greatly improving the use stability of the plastic shell protection assembly 200; at the same time, the binding member 240 can also be kept on the same horizontal plane through the limiting sleeve 260, so that the pressure of the binding member 240 clamped on the outer peripheral wall of the ultra-thin corrugated paper box 100 through each support side plate 230 is consistent, thereby making the ultra-thin corrugated paper box 100 bear uniform stress, avoiding the deformation of the ultra-thin corrugated paper box 100 due to excessive local pressure, not only effectively preventing the ultra-thin corrugated paper box 100 from being squeezed due to deformation, but also prolonging the service life of the ultra-thin corrugated paper box 100.

[0045] It can be understood that when the bundling operation is performed on the support side plate 230, if the bundling force of the bundling piece 240 is too large, the pressure between the bundling piece 240 and the support side plate 230 is likely to be too large, which causes the pressure between the support side plate 230 and the ultra-thin corrugated paper box 100 to be too large, so that the possibility of deformation or even damage of the ultra-thin corrugated paper box 100 due to excessive pressure is greatly increased; if the bundling force of the bundling piece 240 is too small, the pressure for embedding the tooth-shaped limiting piece 300 into the surface paper layer 110 of the ultra-thin corrugated paper box 100 cannot be provided, so that the limiting effect of the plastic shell protection assembly 200 is greatly reduced, thereby greatly increasing the phenomenon that the ultra-thin corrugated paper box 100 is separated from the plastic shell protection assembly 200 due to large vibration or impact in the transportation process, thereby greatly increasing the risk of damage to the ultra-thin corrugated paper box 100 and the goods.

[0046] As shown in Figures 1 to 2 In one embodiment, the bundling piece 240 is an elastic bundling piece, so that the bundling piece 240 has elastic properties, which not only allows the bundling piece 240 to buffer the pressure between the support side plate 230 and the ultra-thin corrugated paper box 100 through its own elastic properties, thereby avoiding the phenomenon that the ultra-thin corrugated paper box 100 deforms due to excessive pressure, but also allows the bundling piece 240 to absorb excess energy through elastic deformation when the bundling force of the bundling piece 240 is too large, thereby dispersing the pressure between the bundling piece 240 and the support side plate 230, reducing local stress concentration, and greatly reducing the possibility that the ultra-thin corrugated paper box 100 deforms or even is damaged due to excessive pressure, thereby greatly increasing the service life of the ultra-thin corrugated paper box 100. At the same time, when the bundling force of the bundling piece 240 is too small, the bundling piece 240 can tightly abut against the support side plate 230 through its own elastic force, which not only ensures the bundling stability of the bundling piece 240, but also provides pressure for embedding the tooth-shaped limiting piece 300 into the surface paper layer 110 of the ultra-thin corrugated paper box 100, thereby ensuring that the tooth-shaped limiting piece 300 can be embedded into the surface paper layer 110 of the ultra-thin corrugated paper box 100, effectively reducing the possibility that the ultra-thin corrugated paper box 100 is separated from the installation limiting groove 210 due to vibration or impact during transportation, thereby greatly reducing the risk of damage to the ultra-thin corrugated paper box 100 and the goods. Further, the elastic bundling piece is an elastic soft rubber rope or an elastic silica gel rope.

[0047] It can be understood that in the process of embedding the tooth-shaped limiting part 300 into the face paper layer 110 of the ultra-thin corrugated carton 100, the ultra-thin corrugated carton 100 will wear the tooth-shaped limiting part 300. After the tooth-shaped limiting part 300 is embedded into the face paper layer 110 of the ultra-thin corrugated carton 100 for many times, the tooth-shaped limiting part 300 will become blunt due to excessive wear, so that the tooth-shaped limiting part 300 needs to exert greater force to be embedded into the face paper layer 110 of the ultra-thin corrugated carton 100, thereby making the ultra-thin corrugated carton 100 easily deformed or even damaged due to excessive pressure, thereby greatly reducing the service life of the ultra-thin corrugated carton 100, and greatly increasing the installation difficulty of the plastic shell protection assembly 200 and the ultra-thin corrugated carton 100.

[0048] As shown in Figures 1 to 5 In one embodiment, the tooth-shaped limiting part 300 is detachably mounted on the support side plate 230, so that the tooth-shaped limiting part 300 can be regularly replaced and maintained, so that the tooth-shaped limiting part 300 can maintain a sharp state, thereby easily embedding the tooth-shaped limiting part 300 into the face paper layer 110 of the ultra-thin corrugated carton 100 without providing greater pressure. Not only greatly reduces the installation difficulty of the plastic shell protection assembly 200 and the ultra-thin corrugated carton 100, but also avoids the phenomenon that the ultra-thin corrugated carton 100 is deformed or even damaged due to excessive pressure between the ultra-thin corrugated carton 100 and the support side plate 230, thereby greatly improving the service life of the ultra-thin corrugated carton 100.

[0049] As shown in Figures 3 to 4 In one embodiment, the tooth-shaped limiting part 300 is a stainless steel tooth-shaped limiting part 300, so as to improve the structural strength and wear resistance of the tooth-shaped limiting part 300, thereby improving the service life of the tooth-shaped limiting part 300 and reducing the maintenance cost of the tooth-shaped limiting part 300.

[0050] As shown in Figures 3 to 4 In one embodiment, the tooth-shaped limiting part 300 includes a fixed part 310, a tooth-shaped limiting part 320, and a third fastener (not shown), the tooth-shaped limiting part 320 is fixedly connected with the fixed part 310, the fixed part 310 is formed with a third positioning hole 311, the support side plate 230 is formed with a third threaded hole 233 adjacent to one side of the installation limiting groove 210, the third fastener is screwed into the third threaded hole 233 through the third positioning hole 311, so as to further reduce the installation and dismounting difficulty between the tooth-shaped limiting part 300 and the support side plate, thereby greatly reducing the replacement and maintenance difficulty of the tooth-shaped limiting part 300, and greatly reducing the maintenance cost of the plastic shell protection assembly 200; the tooth-shaped limiting part 320 is embedded in the face paper layer 110 of the ultra-thin corrugated carton 100, so that the corrugated carton can be firmly limited in the installation limiting groove 210.

[0051] As shown in Figures 3 to 4As shown, in one embodiment, the fixed part 310 and the tooth-shaped limiting part 320 are integrally formed to improve the compactness of the tooth-shaped limiting part 300.

[0052] It can be understood that the alignment between the third positioning hole 311 and the third threaded hole 233 is difficult, and during the threaded connection of the fixed part 310 and the support side plate 230, the fixed part 310 is easily affected by external factors such as vibration or impact to cause sliding or even displacement, which in turn causes the third positioning hole 311 and the third threaded hole 233 to be easily misaligned or even misaligned, thereby greatly increasing the installation difficulty and maintenance difficulty of the tooth-shaped limiting part 300 and the support side plate 230.

[0053] As shown, Figures 3 to 8 In one embodiment, the support side plate 230 is formed with a positioning groove 234 adjacent to one side of the installation limiting groove 210, which is matched with the fixed part 310. The fixed part 310 is pre-fixed in the positioning groove 234, and the third threaded hole 233 is formed in the groove bottom of the positioning groove 234, so that the fixed part 310 can be quickly and accurately installed at the predetermined position of the support side plate 230 through the positioning groove 234. Not only does this greatly reduce the alignment difficulty of the third positioning hole 311 and the third threaded hole 233, but it also allows the fixed part 310 to be firmly limited in the positioning groove 234, preventing the fixed part 310 from sliding or even displacing due to external factors such as vibration or impact when it is threaded onto the support side plate 230. This effectively avoids misalignment or even misalignment between the third positioning hole 311 and the third threaded hole 233, greatly reducing the production and assembly difficulty of the tooth-shaped limiting part 300 and the support side plate 230, and thus greatly reducing the production cost and maintenance cost of the plastic shell protection assembly 200.

[0054] It can be understood that the tooth-shaped limiting part 320 needs to abut and partially embed in the surface paper layer 110 of the ultra-thin corrugated carton 100 to limit the ultra-thin corrugated carton 100 in the installation limiting groove 210. If the tooth-shaped limiting part 320 does not have enough sharpness when embedded in one end of the ultra-thin corrugated carton 100, the tooth-shaped limiting part 320 cannot easily embed in the surface paper layer of the ultra-thin corrugated carton 100, requiring greater pressure between the tooth-shaped limiting part 320 and the ultra-thin corrugated carton 100 to embed the tooth-shaped limiting part 320 in the cotton layer paper of the ultra-thin corrugated carton 100, which can easily cause the ultra-thin corrugated carton 100 to deform or even be damaged due to excessive pressure, thereby greatly reducing the service life of the ultra-thin corrugated carton 100.

[0055] As shown, Figures 3 to 8As shown in the drawings, in one embodiment, the tooth-shaped limiting part 320 is embedded in one end of the face paper layer 110 of the ultra-thin corrugated carton 100 at an angle to reduce the contact area between the tooth-shaped limiting part 320 and the face paper layer 110 of the ultra-thin corrugated carton 100, reduce the embedding resistance of the tooth-shaped limiting part 320, and enable the tooth-shaped limiting part 320 to be easily embedded into the face paper layer 110 of the ultra-thin corrugated carton 100, effectively avoiding the phenomenon that the ultra-thin corrugated carton 100 is deformed or even damaged due to excessive pressure.

[0056] As shown in the drawings, Figures 3 to 8 in one embodiment, the angle of the angle is 15°-30° to ensure that the tooth-shaped limiting part 320 can have better sharpness, so that the tooth-shaped limiting part 320 can be easily embedded into the face paper layer 110 of the ultra-thin corrugated carton 100, thereby improving the convenience of use of the plastic shell protection assembly 200.

[0057] As shown in the drawings, Figures 3 to 8 in one embodiment, the thickness of the tooth-shaped limiting part 320 is 0.3mm-0.5mm to improve the sharpness of the tooth-shaped limiting part 320 while ensuring that the tooth-shaped limiting part 320 has better structural strength, not only enabling the tooth-shaped limiting part 320 to be easily embedded into the face paper layer 110 of the ultra-thin corrugated carton 100, but also enabling the ultra-thin corrugated carton 100 to be firmly limited in the installation limiting groove 210, while also avoiding damage to the ultra-thin corrugated carton 100 caused by the tooth-shaped limiting part 320, and even damage, thereby greatly improving the service life of the ultra-thin corrugated carton 100.

[0058] As shown in the drawings, Figures 3 to 8 in one embodiment, the length of the tooth-shaped limiting part 320 is less than the thickness of the face paper layer 110 of the ultra-thin corrugated carton 100 to avoid damage to the corrugated core 120 of the ultra-thin corrugated carton 100 caused by the tooth-shaped limiting part 320 penetrating through the face paper layer 110 of the ultra-thin corrugated carton 100, and to ensure that the ultra-thin corrugated carton 100 can have better cushioning protection effect, so that the ultra-thin corrugated carton 100 can cushion and protect the goods, thereby improving the transportation safety of the goods.

[0059] As shown in the drawings, Figures 3 to 8 in one embodiment, the length of the tooth-shaped limiting part 320 is 0.12mm-0.18mm, not only avoiding damage to the corrugated core 120 of the ultra-thin corrugated carton 100 caused by the tooth-shaped limiting part 320 penetrating through the face paper layer 110 of the ultra-thin corrugated carton 100, but also making the embedding marks of the ultra-thin corrugated carton 100 almost invisible, effectively avoiding damage such as tearing and indentation of the face paper layer 110 of the ultra-thin corrugated carton 100 caused by the tooth-shaped limiting part 320, thereby greatly improving the service life of the ultra-thin corrugated carton 100.

[0060] It can be understood that when the bundling member 240 is wound on the side of each support side plate 230 away from the toothed limiting member 300, if the two end corners of the side of the support side plate 230 away from the toothed limiting member 300 are too sharp, the corners of the support side plate 230 are easy to damage or even break the bundling member 240, so that the service life of the bundling member 240 is greatly reduced.

[0061] As shown in the drawings, Figures 3 to 5 In one embodiment, the two end corners of the side of each support side plate 230 away from the toothed limiting member 300 are rounded corners 235, so as to avoid the damage or even breakage of the bundling member 240 during the bundling process due to the too sharp corners of the support side plate 230, thereby greatly improving the bundling stability and service life of the bundling member 240.
