[0002] Traditional cardboard boxes often use a single-layer cardboard structure, which has limited strength and weak load-bearing capacity, making them susceptible to deformation or damage from external impacts. During transportation and storage, the instability of the box structure makes goods vulnerable to damage. Furthermore, traditional cardboard boxes typically lack a dedicated cushioning layer, or the existing cushioning layer is insufficient to provide adequate protection. When goods are subjected to vibration or collision, the inadequacy of the cushioning layer leaves them still easily damaged. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-6 This utility model provides a reinforced packaging box with a double-layer structure, including a box body 1 and a box cover 2 disposed on the box body 1. The box body 1 includes an outer box body 101 and an inner box body 102 disposed inside the outer box body 101. At least one vertically intersecting first C-shaped reinforcement frame 3 and second C-shaped reinforcement frame 4 are fixedly connected between the outer box body 101 and the inner box body 102. A first buffer layer 5 is filled between the outer box body 101 and the inner box body 102. The box cover 2 includes an outer box cover 201 and an inner box cover 202 disposed inside the outer box cover 201. A second buffer layer 6 is filled between the outer box cover 201 and the inner box cover 202.

[0025] This reinforced packaging box with a double-layer structure utilizes a combination of an outer box body 101 and an inner box body 102, as well as an outer box lid 201 and an inner box lid 202, to form a double-layer structure. At least one vertically intersecting first U-shaped reinforcing frame 3 and a second U-shaped reinforcing frame 4 are provided between the outer box body 101 and the inner box body 102, significantly enhancing the overall structural strength of the packaging box and improving its load-bearing capacity. This effectively resists external impacts and prevents deformation or damage during transportation or storage. Simultaneously, a first buffer layer 5 and a second buffer layer 6 are filled between the outer box body 101 and the inner box body 102, and between the outer box lid 201 and the inner box lid 202, respectively, further absorbing and dispersing external impacts, providing additional protection for the contents and reducing the risk of damage caused by vibration or collision. This reinforced packaging box with a double-layer structure provides both structural strength and cushioning protection, effectively protecting the contents and improving transportation efficiency.

[0026] The aforementioned reinforced packaging boxes with a double-layer structure can be any of the following: cuboid, cylindrical, or other three-dimensional shapes. This allows the packaging boxes to adapt to items of different shapes and sizes, improving their versatility and applicability.

[0027] Each side of the box body 1 is fixedly connected with at least two fixing buckles 7, and each side of the box lid 2 is fixedly connected with a connecting buckle 8 corresponding to the fixing buckle 7. After being connected by the fixing buckle 7 and the connecting buckle 8, the box body 1 and the box lid 2 can be firmly connected without the need for tape or rope, so as to prevent them from falling off due to vibration or collision during transportation.

[0028] At least one square reinforcing frame 9, which is staggered with the first C-shaped reinforcing frame 3 and the second C-shaped reinforcing frame 4, is fixedly connected between the outer box body 101 and the inner box body 102, further enhancing the structural strength of the paper box. In particular, it can provide additional support when subjected to lateral pressure. At least one cross-shaped third transverse reinforcing frame 10 is fixedly connected between the outer box cover 201 and the inner box cover 202, which enhances the load-bearing capacity and structural stability of the box cover 2 and ensures that the box cover 2 also has excellent structural strength.

[0029] Both the first buffer layer 5 and the second buffer layer 6 are made of expanded foam. The expanded foam has good elasticity and cushioning performance, which can effectively absorb and disperse external impact force and provide better protection for the contents. Multiple glue injection holes 11 are opened on the bottom and sides of the outer box 101 and the top surface of the outer box cover 201, which facilitates the injection of expanded foam into the buffer layer during the production process. In the later use, when the buffer layer is damaged, glue can be injected into it through the glue injection holes 11 at any time. The thickness of the first buffer layer 5 and the second buffer layer 6 is 1-10cm. This thickness range can provide good protection while maintaining the lightness of the packaging.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
