Description

Technical Field

[0001] The utility model relates to a reusable paper corner protector. Background Art

[0002] Paper corner protectors, also known as edge boards, are one of the most popular packaging products in the world. They are used to replace wood packaging and other bulky packaging methods. They are low-priced, light, strong, and meet environmental protection requirements. Also known as paper corner protectors or corner protector paperboard, edge boards, corner paper, and paper angle steel, they are generally made of tube paper and kraft paper through a set of corner protector machines. The two ends are smooth and flat, without obvious burrs, and are perpendicular to each other. They can replace wood and are 100% recyclable and reused. They are one of the ideal new green packaging materials. The main buyers of paper corner protectors are the construction industry, aluminum industry, steel industry, and other metal industries. In addition, they also include the brick industry, candy industry, frozen food, daily necessities, home appliances, chemicals, pharmaceuticals, computers, and other high-tech products, etc. This is because these products have a large number of surfaces and corners that need to be protected. In addition, paper corner protectors can also be used in the transportation of fruits. They not only play a protective role, but also allow the goods to be ventilated during transportation.

[0003] In the authorized Chinese utility model patent "Announcement No.: CN220181564U, Name: A Paper Corner Protector", it utilizes a first side panel and a second side panel connected to a base to fold to form a first limiting portion and a second limiting portion for wrapping the corner of a product, so as to facilitate the user to store the paper corner protector of this application when not in use. However, the above application lacks supporting force when folded into a paper corner protector, resulting in the paper corner protector being extremely easy to deform during use. That is, although the above application achieves the purpose of convenient storage, its own protective performance is reduced, resulting in the paper corner protector being extremely easy to be damaged and difficult to reuse.

[0051] In the present technical solution, the first straight paperboard 1 and the second straight paperboard 2 can be assembled by using the connecting piece 3, so that the first straight paperboard 1 and the second straight paperboard 2 can be distributed at right angles when in use, and can be stacked and stored separately when not in use, which is convenient for the transportation and storage of the first straight paperboard 1 and the second straight paperboard 2. At the same time, under the action of the connecting piece 3 and the supporting layer 8, the assembled paper corner protector has better supporting performance and is not easy to deform, thereby increasing the service life of the paper corner protector, and is easy to disassemble and can be reused many times.

[0052] The connecting member 3 includes a first connecting plate 31 and a second connecting plate 32, and the first connecting plate 31 and the second connecting plate 32 are fixedly connected to one side of the first straight paperboard 1 and the second straight paperboard 2 respectively;

[0053] The first connecting plate 31 and the second connecting plate 32 are connected by a locking block 33 .

[0054] In the present technical solution, the first straight paperboard 1 and the second straight paperboard 2 can be assembled and disassembled by using the connecting piece 3, so as to facilitate the use and storage of the paper corner protectors.

[0055] A connecting groove is formed on one side of the first connecting plate 31 and the second connecting plate 32 , and the engaging block 33 is connected to the first connecting plate 31 and the second connecting plate 32 through the connecting groove.

[0056] Anti-slip bars 34 are connected to both sides of the locking block 33 , and the anti-slip bars 34 are locked into the connecting grooves.

[0057] In the present technical solution, the anti-slip strip 34 can prevent the locking block 33 from slipping out of the first connecting plate 31 or the second connecting plate 32, thereby increasing the stability of the first straight paperboard 1 and the second straight paperboard 2 after assembly.

[0058] During assembly, the first straight cardboard 1 and the second straight cardboard 2 are moved in opposite directions respectively. At this time, the engaging block 33 and the anti-slip strip 34 slide in the connecting groove respectively, so that the upper and lower sides of the first straight cardboard 1 and the second straight cardboard 2 are respectively on the same surface.
