Description

Technical Field

[0001] This utility model relates to the field of paper corner protectors, and more specifically, it relates to a spliced ​​paper corner protector. Background Technology

[0002] Paper corner protectors are an environmentally friendly packaging material made from materials such as kraft paper and yarn tube paper through bonding and pressing. Different specifications can be customized according to packaging needs. They are characterized by high hardness and good toughness, effectively protecting the edges and corners of goods from collisions and squeezing damage during transportation and handling. They also reinforce cartons and pallets, improving the overall stability of the packaging.

[0003] However, traditional paper corner protectors are limited by their fixed angle design, making them only suitable for protecting the edges and corners of goods of specific sizes and shapes. For example, they are only suitable for boxed goods with regular right angles. When encountering irregular polygonal goods with special angles, traditional fixed-angle paper corner protectors cannot fit tightly against the edges and corners of the goods, resulting in a large number of blind spots in protection. This limitation not only requires companies to stock multiple sizes of paper corner protectors when dealing with diverse goods, increasing warehousing and procurement costs, but also leads to a high rate of edge and corner damage during transportation due to poor protective effect, making it difficult to meet the efficient and precise protection requirements of modern logistics.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a spliced ​​paper corner protector. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a splicing paper corner protector.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a splicing paper corner protector, comprising two symmetrically arranged guard plate parts and a flexible connecting part connecting the two guard plate parts. The two guard plate parts form a V-shaped structure that can change the angle through the flexible connecting part. Corresponding base plates are spliced ​​between the bottoms of the guard plate parts, and the angle between the guard plate parts is fixed by installing the base plates.

[0007] Preferably, a groove is provided on the bottom of the protective plate, and protrusions that can be inserted into the groove are provided on the side ends of the bottom plate.

[0008] Preferably, a groove is provided on the bottom of the protective plate, and protrusions that can be inserted into the groove are provided on both sides of the bottom plate.

[0009] Preferably, Velcro A is installed on the mating surface of the side plate and the protective plate, and Velcro B is installed on the mating surface of the protective plate and the side plate.

[0010] Preferably, the protective panel is detachably connected to the housing via Velcro C.

[0011] Preferably, the flexible connecting part 2 is made of high-strength corrugated cardboard with a thickness of 0.3 to 0.8 mm, and the protective plate part is composed of a three-layer composite structure, including an outer waterproof kraft paper layer, a middle honeycomb cardboard layer and an inner antistatic coating layer.

[0012] Preferably, the outer surfaces of the protective plate, the flexible connection, and the base plate are all covered with a nano-silica waterproof coating.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model fully utilizes the bendable characteristics of the flexible connecting part and the combination of multiple specifications of base plates to break through the limitation of the fixed angle of traditional paper corner protectors. It can quickly adapt to irregular polygonal goods as well as normal goods, significantly improving the versatility and application scenario coverage of paper corner protectors, reducing enterprises' dependence on multiple specifications of paper corner protectors, reducing warehousing and procurement costs, and the splicing structure makes the overall assembly and disassembly of paper corner protectors more convenient and easy to reuse, thus solving the problems in the background technology.

[0015] 2. This utility model enables rapid positioning of the base plate and the protective plate through the insertion process of the groove and the protrusion, greatly improving the splicing efficiency and meeting the needs of rapid packaging operations.

[0016] 3. In this utility model, the side plate and the protective plate are mechanically connected by the protruding head. This connection method can effectively resist vibration and impact during the transportation of goods, prevent the bottom plate from falling off accidentally, and ensure the stability of the overall structure of the paper corner protector. Moreover, when the bottom plate needs to be replaced to adapt to different angles, the mechanically connected structure design allows for quick disassembly by applying reasonable force, which is convenient for reuse.

[0024] like Figure 1-5 As shown, this utility model provides a splicing paper corner protector, including two symmetrically arranged guard plate parts 1 and a flexible connecting part 2 connecting the two guard plate parts 1. The two guard plate parts 1 form a V-shaped structure that can change the angle through the flexible connecting part 2. Corresponding base plates 3 are spliced ​​between the bottoms of the guard plate parts 1. The angle between the guard plate parts 1 is fixed by installing the base plates 3.

[0025] Utilizing the bendable nature of the flexible connector 2, the angle between the two protective panels 1 can be flexibly adjusted to accommodate the corners of goods at different angles. When irregular polygonal goods are required, the protective panel 1 can be adjusted to a suitable angle first, and then the matching base plate 3 can be spliced ​​and installed at the bottom of the protective panel 1 (different base plates 3 are used for different angles). Through the splicing structure between the base plate 3 and the protective panel 1, the adjusted angle of the protective panel 1 is fixed, so that the paper corner protector fits tightly against the corners of the goods. The base plate 3 can also cover the opening between the bottoms of the two protective panels 1. On the one hand, it makes full use of the bendable nature of the flexible connector 2 and the combination of multiple specifications of base plates 3, breaking through the limitation of the fixed angle of traditional paper corner protectors, and can quickly adapt to various irregular polygons. For both cargo and regular goods, the paper corner protectors significantly improve their versatility and application scope (simply replace the base plate 3), reducing companies' reliance on multiple specifications of paper corner protectors and lowering warehousing and procurement costs. On the other hand, the base plate 3 effectively covers the bottom openings of the two protective plates 1, preventing the edges and corners of the goods from directly contacting the outside world and avoiding damage caused by collisions and friction during transportation, further enhancing the protective effect. In addition, the splicing structure makes the overall assembly and disassembly of the paper corner protectors more convenient and easy to reuse (by replacing different base plates 3, paper corner protectors with different angles can be formed and then used).

[0026] The flexible connecting part 2 is made of high-strength corrugated cardboard with a thickness of 0.3-0.8mm. This thickness range ensures that the corrugated cardboard has good flexibility, making it less prone to breakage during bending and allowing for flexible adjustment of the angle between the two protective panels 1 to adapt to the protection needs of goods of different shapes. Its high strength also ensures the integrity of the overall structure of the paper corner protector when subjected to external pressure and collisions during cargo transportation and storage, effectively dispersing and buffering impact forces. Furthermore, the aforementioned protective panel 1 is composed of a three-layer composite structure, including an outer layer of waterproof kraft paper, a middle layer of honeycomb cardboard, and an inner layer of antistatic coating. The outer layer of waterproof kraft paper effectively resists the erosion of the paper corner protector by a humid environment, preventing the paper corner protector from softening due to water absorption and reducing its protective strength in rainy weather or high-humidity storage environments, ensuring its structural stability. The middle layer of honeycomb cardboard, with its unique hexagonal... The honeycomb structure achieves high compressive strength with lightweight materials, effectively dispersing pressure and saving material costs when cushioning impacts during cargo transportation. The inner antistatic coating prevents static electricity from being generated during friction, preventing dust adsorption or malfunction of electronic goods. It is especially suitable for protecting static-sensitive goods such as electronic components and precision instruments. The three-layer structure works synergistically to significantly improve the durability, protection, and application adaptability of the paper corner protector. Moreover, the outer surfaces of the aforementioned protective plate 1, flexible connection 2, and base plate 3 are all covered with a nano-silica waterproof coating. The nano-silica coating forms a dense waterproof film on the surface of the paper corner protector, preventing water droplets from penetrating into the internal material. This effectively prevents the paper corner protector from softening, deforming, or even breaking due to moisture, thus extending its service life.

[0027] Furthermore, a groove 101 is provided on the bottom of the protective plate 1, and a protrusion 301 that can be inserted into the groove 101 is provided on each side of the bottom plate 3. The head of the protrusion 301 is fixedly connected to a side plate 302, and the side plate 302 is mechanically engaged with the protective plate 1. The above design has the following advantages:

[0028] Firstly, the insertion process of the groove 101 and the protrusion 301 enables rapid positioning of the base plate 3 and the protective plate 1, greatly improving splicing efficiency and meeting the needs of rapid packaging operations. Secondly, the side plate 302, which is fixedly connected to the head of the protrusion 301, forms a mechanical hook connection with the protective plate 1. This connection method can effectively resist vibration and impact during cargo transportation, prevent the base plate 3 from accidentally falling off, and ensure the stability of the overall structure of the paper corner protector. Thirdly, when it is necessary to replace the base plate 3 to adapt to different angles, the mechanical hook connection structure design allows for quick disassembly by applying reasonable force, facilitating reuse.

[0029] The following is the specific structure of the mechanical hook connection between the side plate 302 and the protective plate 1: Velcro A4 is installed on the mating surface of the side plate 302 and the protective plate 1, and Velcro B5 is installed on the mating surface of the protective plate 1 and the side plate 302. That is, after the protrusion 301 is fully inserted into the groove 101, the side plate 302 and the protective plate 1 are tightly pressed together. At this time, Velcro A4 and Velcro B5 are in contact, and the hook and loop sides of the Velcro are in contact with each other. This provides a stable connection force when the bottom plate 3 and the protective plate 1 are spliced, effectively preventing the bottom plate 3 from loosening and falling off due to vibration and shaking during transportation, ensuring the protective effect of the paper corner protectors on the corners of the goods. At the same time, the Velcro connection operation is extremely simple, requiring no tools. Workers can quickly complete the assembly and disassembly, greatly improving packaging efficiency.

[0030] Meanwhile, the protective panel 1 of this utility model is also detachably connected to the goods via Velcro C6. By first installing Velcro that is compatible with Velcro C6 on the goods, the protective panel 1 can be connected to the goods, which facilitates quick disconnection between the paper corner protector and the goods and facilitates the reuse of the paper corner protector.
