[0002] Paper corner protectors are widely used in the logistics packaging of various items, especially for protecting the corners of fragile or valuable items such as photo frames and picture frames, to prevent the corners of items from being damaged during transportation and storage.
[0003] At present, most of the paper corner protectors on the market are made of kraft paper or other paper materials, which are folded around the corners of the objects and then glued or nailed to achieve the packaging of the corners of the objects. Although the existing paper corner protectors have a certain protective effect, they are relatively simple in structure and have limited impact resistance, which needs to be improved. Utility Model Content
[0004] The purpose of the present application is to provide a paper corner protector in order to solve the problem of limited impact resistance of existing paper corner protectors.
[0005] The paper corner protector provided in this application adopts the following technical solution:
[0006] A paper corner guard comprises a first side guard plate, a second side guard plate, a bottom guard plate and a rear guard plate arranged between the first side guard plate and the second side guard plate, wherein the first side guard plate and the second side guard plate are both provided with reinforcing members for increasing their thickness, and the bottom guard plate, the rear guard plate, the first side guard plate and the second side guard plate are combined to form an installation groove.
[0007] By adopting the above technical solution, the installation groove is used for inserting the corners of the items to be packaged, and the bottom guard plate, the rear guard plate, the first side guard plate and the second side guard plate can protect the four sides of the corners of the items. The thickness of the first side guard plate and the second side guard plate is increased by the reinforcement to enhance the impact resistance and improve the protective effect of the paper corner protector.
[0008] Optionally, the two reinforcements are respectively a first reinforcement plate arranged at one end of the first side guard plate and a second reinforcement plate arranged at one end of the second side guard plate, one side of the bottom guard plate is connected to one side of the first side guard plate, and the other opposite side is connected to one side of the second side guard plate, one side of the rear guard plate is connected to one side of the first side guard plate, and the other opposite side is connected to one side of the second reinforcement plate, and the first side guard plate is connected to the side opposite to the first reinforcement plate via a first connecting plate.
[0009] By adopting the above technical scheme, a first side guard plate, a second side guard plate, a bottom guard plate, a rear guard plate, a first reinforcing plate, a second reinforcing plate and a first connecting plate are integrally formed by cutting, stamping and other processing on a piece of cardboard, and the bottom guard plate and the rear guard plate are perpendicular to each other by bending the plates relative to each other, the first side guard plate and the second side guard plate are respectively arranged on both sides, the first reinforcing plate is arranged on the inner end surface of the first side guard plate, and the second reinforcing plate is arranged on the inner end surface of the second side guard plate.
[0010] Optionally, support plates are provided on opposite sides of the first reinforcing plate, wherein one of the support plates abuts against one end of the bottom guard plate, and the other support plate abuts against one end of the rear guard plate.
[0011] By adopting the above technical solution, the two support plates are respectively abutted against the inner end surfaces of the bottom guard plate and the rear guard plate to increase the thickness of the bottom guard plate and the rear guard plate to enhance the impact resistance and improve the protective effect of the paper corner guard.
[0012] Optionally, a third reinforcement plate is provided at one end of the second reinforcement plate.
[0013] By adopting the above technical solution, the third reinforcing plate increases the thickness of the second reinforcing plate to enhance the impact resistance and improve the protective effect of the paper corner protector.
[0014] Optionally, the first reinforcing plate and the supporting plate are combined to form a groove for the third reinforcing plate to be embedded in.
[0015] By adopting the above technical solution, the third reinforcing plate is embedded in the groove, and the opposite sides of the third reinforcing plate are respectively abutted against the corresponding support plates, so that the support plate is further abutted against the bottom guard plate and the rear guard plate by force, reducing the deformation of the bottom guard plate and the rear guard plate due to impact, and increasing the overall structural strength of the paper corner guard.
[0016] Optionally, a fixing block is provided on one side of the second side guard plate, the second reinforcing plate is provided with a fixing hole cooperating with the fixing block, and the fixing block is provided with a sharp corner for limiting the fixing block from moving out of the fixing hole.
[0017] By adopting the above technical solution, the fixing block is inserted into the fixing hole. During the insertion process, the sharp corner first abuts against the hole wall of the fixing hole to generate deformation. After the sharp corner passes through the fixing hole, the deformation is restored. The sharp corner abuts against the inner end surface of the second reinforcing plate to limit the fixing block from moving out of the fixing hole, thereby realizing the assembly and fixation of the paper corner protector, eliminating the process of gluing or nailing, and reducing the inconvenience caused by the gluing or nailing process.
[0018] Optionally, the support plate is provided with a clearance groove corresponding to the fixing hole and cooperating with the fixing block.
[0019] By adopting the above technical solution, the positioning groove is used to accommodate the fixing block, thereby reducing the extrusion deformation between the support plate and the fixing block, and making the structure of the paper corner protector more reasonable.
[0020] Optionally, the second reinforcement plate and the third reinforcement plate are both provided with a first installation notch connected to the installation groove, and the second side guard plate is provided with a second installation notch corresponding to the first installation notch.
[0021] By adopting the above technical solution, the first installation notch and the second installation notch can facilitate the packaging of the paper corner protector from one side of the corner of the article, thereby improving the convenience of packaging the paper corner protector.
[0022] Optionally, the second reinforcing plate is connected to the third reinforcing plate at a side opposite to the third reinforcing plate via a second connecting plate.
[0023] By adopting the above technical solution, the second reinforcing plate and the third reinforcing plate are connected via the second connecting plate to achieve one-piece molding.
[0024] Optionally, one side of the second side guard plate is provided with a clearance surface corresponding to the first connecting plate and the second connecting plate.
[0025] By adopting the above technical solution, a clearance surface is set so that one side of the second side guard plate corresponds to the first connecting plate and the second connecting plate, thereby ensuring the flatness of one side of the paper corner protector and improving the overall aesthetics.
