Detailed Implementation
[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0017] This utility model provides an environmentally friendly molded pulp corner plug, including a main support 1, a bottom support 2, and a side support 3. The bottom support 2 is connected to one side of the main support 1, and the side support 3 is connected to the other side of the main support 1. The main support 1 includes a first straight platform 11 and a first inclined platform 12. The first inclined platform 12 is connected to the bottom of the first straight platform 11. When the corner plug is assembled, the bottom support 2 is rotated and inserted into the interior of the first inclined platform 12. The side support 3 is connected to the inclined surface of the first inclined platform 12.
[0018] Corner inserts are located at the corners of the product in the packaging, providing cushioning protection for the corners. They can also be used to connect two sections of paper tube 7, strengthening the connection and enhancing protection. Figure 5 As shown. The plug provided by this utility model is made by pulp molding. All materials selected in this solution are green, reusable and recyclable. It is integrally molded, which can not only reduce mold opening costs, but also improve production efficiency and reduce overall costs.
[0019] This design employs a three-section paper tray structure: a main tray 1, a side tray 3, and a bottom tray 2. The bottom structure of the main tray 1 cooperates with the bottom tray 2 to stabilize both the main tray 1 and the bottom tray 2, preventing them from moving. The side tray 3 is further secured by a boss and a groove. The corner insert is L-shaped, and the main tray 1 is also designed in an L-shape. The bottom tray 2 is shaped like an inverted bucket, and after rotation, it fits into the inner cavity of the first inclined platform 12 when placed inside the main tray 1. The side tray 3 is trapezoidal, forming an L-shaped corner insert when combined with the main tray 1. This design enhances the bottom cushioning strength through the bottom tray 2 and the side cushioning strength through the side tray 3.
[0020] In one embodiment of this utility model, the main support 1, the bottom support 2, and the side support 3 are all hollow structures. The hollow structure reduces the weight of the corner brackets and facilitates their assembly, reducing assembly difficulty.
[0021] In another embodiment of this utility model, the first straight platform 11 is recessed and provided with a first reinforcing member 13, which is connected to the bottom of the base 2. In another embodiment of this utility model, the bottom of the base 2 is recessed and provided with a second reinforcing member 20, which engages with the first reinforcing member 13 during corner assembly. The opening of the base 2 faces upward, and the first reinforcing member 13 and the second reinforcing member 20 can enhance the strength of the paper tray and improve the cushioning strength. At the same time, they can engage with the second reinforcing member 20 located on the base 2 to strengthen the tightness of the connection between the base 2 and the main tray 1.
[0022] In another embodiment of this utility model, the bottom end of the second reinforcing member 20 is provided with an avoidance hole 6. The avoidance hole 6 is designed to prevent the bottom support 2 from interfering with the bottom edge of the main support 1 when it is rotated and folded towards the main support 1.
[0023] In another embodiment of the present invention, the side support 3 includes a second straight platform 30 and a second inclined platform 31. The second inclined platform 31 is disposed on one side of the second straight platform 30 and is connected to the first inclined platform 12.
[0024] In another embodiment of this utility model, the inclined surface of the first inclined platform 12 is provided with an insertion block 4 protruding outward, and the inclined surface of the second inclined platform 31 is provided with an insertion groove 5 recessed inward. When the plug angle is combined, the insertion block 4 is inserted into the insertion groove 5, and the inclined surface of the first inclined platform 12 is in contact with the inclined surface of the second inclined platform 31.
[0025] In another embodiment of this utility model, the second straight platform 30 is recessed and provided with a third reinforcing member 32. The third reinforcing member 32 can enhance the strength of the paper tray.
[0026] When the side support 3 is assembled, it is connected to the insertion block 4 set on the first inclined platform 12 through the insertion groove 5, and they fit together. After assembly, the side support 3 can enhance the strength of the first inclined platform 12, increase the contact area with the product, and thus improve the buffer strength.
[0027] In another embodiment of this utility model, the main support 1, the bottom support 2 and the side support 3 are integrally formed.
[0028] The assembly process of the corner fitting is as follows: Fold the base support 2 towards the main support 1, inserting the base support 2 into the inner cavity of the main support 1 and filling the interior of the first inclined platform 12. The base support 2 is designed with positive tolerances for a tighter fit when embedded with the main support 1. Simultaneously, the first reinforcing member 13 also engages with the second reinforcing member 20. Then, fold the side support 3 towards the main support 1, so that the insertion block 4 engages with the insertion slot 5. At this point, the inclined surface of the first inclined platform 12 contacts the inclined surface of the second inclined platform 31, and the second straight platform 30 contacts the first straight platform 11, thus completing the corner fitting assembly.
[0029] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
