Description

Technical Field

[0001] This utility model belongs to the field of cardboard corner protector technology, and more specifically, it relates to a cardboard corner protector that is easy to assemble. Background Technology

[0002] Cardboard corner protectors are needed to protect the edges and corners of goods during transportation to reduce the risk of damage to the edges and corners. The most common cardboard corner protectors are L-shaped and are made by pressing multiple sheets of kraft paper or yarn tube paper and kraft cardboard together with a corner protector machine. When using them, the cardboard corner protectors are attached tightly to the edges and corners of the goods, and then the cardboard corner protectors are packed and secured to the goods with packing straps.

[0003] For example, CN219688048U discloses a foldable cardboard corner protector, which includes a first protective wall unit, on which a second protective wall unit is folded and connected. The first and second protective wall units are folded and connected at a 90° angle and are both ring-shaped folding structures. When the foldable cardboard corner protector of this utility model is folded, the first and second protective wall units are folded and connected at a 90° angle, and the cross-section of the entire cardboard corner protector is L-shaped. During use, it can tightly fit the product surface to cushion and protect the product. At the same time, the first and second protective wall units abut against each other, ensuring the stability of the corner protector during use. In addition, the first and second protective wall units are both ring-shaped folding structures. In addition to providing cushioning space, they are also equipped with a first and a second cushioning plate respectively as a secondary cushioning design, which greatly improves the protective cushioning ability of the first and second protective wall units for the product surface.

[0004] Based on the above, when using packing straps to fix cardboard corner protectors, it is necessary to ensure that the packing straps are pressed in the middle of the corner protector to ensure that the corner protector is subjected to uniform force. However, in actual operation, it is difficult for workers to intuitively judge whether the packing straps are located in the middle of the corner protector, which can easily lead to the packing straps shifting in position and affecting the fixing effect on the corner protector and the goods. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an easy-to-assemble cardboard corner protector. This solves the problem that when using packing straps to secure cardboard corner protectors, it is necessary to ensure the packing straps are pressed into the center of the corner protector to guarantee even force distribution. However, in actual operation, workers often find it difficult to visually determine whether the packing straps are in the center of the corner protector, which can easily lead to misalignment of the packing straps and affect the securing effect on the corner protector and the goods.

[0006] The purpose and function of this utility model, which provides an easy-to-assemble cardboard corner protector, are achieved through the following specific technical means:

[0007] An easily assembled cardboard corner protector includes a first corner protector body, a second corner protector body, a waterproof protective film, a limiting structure, a reinforcing structure, position limiting blocks, anti-slip rubber pads, and an extended corner protector body. The second corner protector body is located to the right of the first corner protector body. The limiting structure is disposed on the outside of the first corner protector body. Two extended corner protector bodies are provided, and the two extended corner protector bodies are respectively inserted into the outside of the first corner protector body and the outside of the second corner protector body. Multiple waterproof protective films are provided, and the multiple waterproof protective films are respectively covered on the outside of the first corner protector body, the outside of the second corner protector body, and the outside of the extended corner protector body. Multiple position limiting blocks are provided, and the multiple position limiting blocks are respectively fixedly connected to the outside of the first corner protector body, the outside of the second corner protector body, and the outside of the extended corner protector body. Multiple anti-slip rubber pads are provided, and the multiple anti-slip rubber pads are respectively adhered to the inside of the multiple position limiting blocks. The reinforcing structure is disposed on the inside of the waterproof protective film.

[0008] Furthermore, the limiting structure includes a position limiting block and a position limiting slot; the position limiting block is fixedly connected to the front side of the first corner protector body; the position limiting slot is opened on the left side of the second corner protector body.

[0009] Furthermore, the limiting structure also includes position limiting holes and position limiting rods; multiple position limiting holes are provided, and the multiple position limiting holes are evenly distributed on the rear side of the first corner protector body, the right side of the second corner protector body, and the outer side of the extended corner protector body.

[0010] Furthermore, the limiting structure also includes arc-shaped rubber pads and positioning adhesive; multiple arc-shaped rubber pads are provided, and multiple positioning adhesives are provided, with the multiple positioning adhesives evenly distributed and adhered to the outer side of the multiple arc-shaped rubber pads; the multiple arc-shaped rubber pads are respectively adhered to the inner side of the multiple waterproof protective films by the multiple positioning adhesives.

[0011] Furthermore, the reinforcement structure includes protective rubber pads and anti-deformation steel plates; multiple protective rubber pads are provided, and the multiple protective rubber pads are respectively adhered to the inner side of the first corner protector body, the inner side of the second corner protector body, and the inner side of the extended corner protector body; multiple anti-deformation steel plates are provided, and the multiple anti-deformation steel plates are respectively adhered to the outer side of the first corner protector body, the outer side of the second corner protector body, and the outer side of the extended corner protector body.

[0012] Furthermore, the reinforcement structure also includes anti-cracking slots and anti-cracking anchors; multiple anti-cracking slots are provided, and the multiple anti-cracking slots are respectively opened on the rear side of the first corner protector body, the right side of the second corner protector body, and the outer side of the extended corner protector body; multiple anti-cracking anchors are provided, and the multiple anti-cracking anchors are respectively inserted through the inner side of the multiple anti-cracking slots.

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

[0014] This invention enables rapid and precise assembly of the first corner protector body, the second corner protector body, and the extended corner protector body. It allows for easy splicing of different components without the need for complex tools, reducing operational difficulty and saving assembly time. It also ensures a stable fit between the corner protector bodies, preventing loosening or misalignment after assembly and guaranteeing the overall stability of the corner protector structure. Furthermore, the insertion and assembly of the extended corner protector body allows for protection of goods of varying lengths, effectively improving the applicability of the corner protectors. The waterproof protective film effectively blocks moisture from the air, preventing the cardboard corner protectors from weakening due to moisture absorption, thus ensuring their support and protection of the goods. When protecting goods with curved corners, the use of positioning adhesive to fix the curved rubber pad between the corner protector and the goods significantly improves the fit, allowing the corner protector to tightly wrap around the curved corners of the goods, avoiding issues of insufficient fit affecting the protective effect and further reducing the risk of damage to the corners of the goods. The protective rubber pad reduces friction between the goods and the cardboard corner protector. The corner protectors are designed to prevent scratches and abrasions on the surface of goods during transportation. Anti-deformation steel plates enhance the overall strength of the cardboard corner protectors, reducing the likelihood of breakage under stress or impact and extending their lifespan. Anti-cracking anchors effectively secure the edges of the corner protectors, preventing cracking and ensuring structural integrity and protection. Position limiting blocks precisely limit the positioning of the strapping when securing it, ensuring it remains centered on the corner protector. This avoids the difficulties workers face in visually judging the strapping's position and the potential for misalignment in traditional operations, resulting in even force distribution and improved securing of both the corner protector and goods. Anti-slip rubber pads increase friction between the strapping and the position limiting blocks, effectively reducing slippage during transport and ensuring a stable fixation. This further enhances the stability of goods during transport, reducing the risk of tilting, shifting, or falling due to loose strapping. Attached Figure Description
