Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0025] With reference to Figure 1 , Figure 2 and Figure 4 , the present application provides an embodiment: a fireproof packaging shell of a box firecracker, comprising an outer box body 1, a top corner anti-collision block 2 is arranged at a top corner of the outer box body 1, an exhaust hole is formed in the top of the outer box body 1, for releasing air inside the outer box body 1, a buffer assembly is arranged on the inner side of the top corner anti-collision block 2, and a fire-retardant assembly is arranged in the inner part of the outer box body 1.

[0026] The fire-retardant assembly comprises a lining paper layer 6, a tile paper layer 7 and a surface paper layer 8, the lining paper layer 6 is arranged on the inner side of the inner wall of the outer box body 1, the tile paper layer 7 is arranged on the inner middle side of the outer box body 1, and the surface paper layer 8 is arranged on the inner outer side of the outer box body 1; the buffer assembly comprises a sliding rod 3, one end of the sliding rod 3 is fixedly connected to the inner side of the top corner anti-collision block 2, and a spring 4 is sleeved on the outer wall of the sliding rod 3.

[0027] Specifically, first, the outer box body 1 adopts a honeycomb design, which not only enhances the impact resistance of the box body, but also improves the fire resistance by reducing heat conduction, further preventing the influence of fire on the internal firecrackers. The honeycomb design can effectively reduce the internal temperature when the packaging shell is faced with a high temperature environment, thereby delaying the spread of fire and reducing the explosion risk of firecrackers. In order to further enhance the fireproof effect, the outer box body 1 is internally provided with a three-layer fire-retardant assembly composed of a lining paper layer 6, a tile paper layer 7 and a face paper layer 8. The lining paper layer 6 is located on the inner side of the inner wall of the outer box body 1, and its main function is to block external heat conduction and prevent the rapid entry of fire into the box body. The tile paper layer 7 is located in the middle of the outer box body 1, and serves to insulate and enhance the fireproof performance. The tile paper itself has high heat resistance and can effectively delay the spread of fire. The face paper layer 8 is located on the outer side of the inner part of the outer box body 1, and as the outermost layer, it enhances the fire resistance of the packaging shell through its fire-resistant properties. The three layers work together to not only effectively prevent the invasion of flames into the outer box body 1, but also withstand certain high temperature pressure, ensuring the integrity of the packaging shell in the event of a fire. In addition, the buffer assembly inside the top corner bumper 2, through the structure of the slide rod 3 and the spring 4, can alleviate the damage to the packaging shell caused by external impact or fire, prevent direct contact between external high temperature or flames and the outer box body 1, and thereby reduce the risk of packaging damage or explosion caused by external fire sources. Overall, the fire threat from the inside and outside is fully considered, and through reasonable design and multiple protection, the overall safety of the packaging shell is improved, the explosion risk in the event of a fire hazard is reduced, and the safe storage and transportation of firecrackers are effectively ensured.

[0028] With reference to Figure 1 and Figure 3 , the inner part of the outer box body 1 is provided with a diagonal reinforcing rib 9, a diagonal reinforcing rib 10, an auxiliary reinforcing rib 11 and a horizontal supporting rib 12. The auxiliary reinforcing rib 11 is arranged on one side of the diagonal reinforcing rib 9 and the diagonal reinforcing rib 10, and one end of the auxiliary reinforcing rib 11 is fixedly connected with one end of the horizontal supporting rib 12. Both ends of the diagonal reinforcing rib 9 and the diagonal reinforcing rib 10 are fixedly connected with the end part of the horizontal supporting rib 12. The outer wall of the slide rod 3 is slidingly connected with the inner part of the outer box body 1. The slide rod 3 is used to guide the expansion and contraction of the spring 4. One end of the spring 4 is fixedly connected with the outer wall of the top corner bumper 2. The other end of the spring 4 is fixedly connected with the outer wall of the outer box body 1. The outer box body 1 is designed in a honeycomb shape to improve the fire resistance of the outer box body 1. The lining paper layer 6 is arranged on one side of the outer wall of the tile paper layer 7. The face paper layer 8 is arranged on the other side of the outer wall of the tile paper layer 7. The diagonal reinforcing rib 9, the diagonal reinforcing rib 10, the auxiliary reinforcing rib 11 and the horizontal supporting rib 12 are all made of glass fiber reinforced plastic 5 to improve the strength, heat resistance, fire resistance of the diagonal reinforcing rib 9, the diagonal reinforcing rib 10, the auxiliary reinforcing rib 11 and the horizontal supporting rib 12. The diagonal reinforcing rib 9 and the diagonal reinforcing rib 10 are arranged in a cross shape to improve the strength of the outer box body 1.

[0029] Specifically, the outer box body 1 is provided with a plurality of reinforcing rib structures, including diagonal reinforcing rib one 9 and diagonal reinforcing rib two 10, auxiliary reinforcing rib 11 and transverse support rib 12, which together form an efficient support system, effectively enhancing the compression resistance and impact resistance of the outer box body 1. Diagonal reinforcing rib one 9 and diagonal reinforcing rib two 10 adopt a cross layout design, which can effectively disperse external impact force, thereby improving the overall strength of the box body 1, so that the outer box body 1 can withstand greater external pressure and impact, avoiding damage to the outer box body 1 caused by external impact, especially during transportation and handling, the outer box body 1 will often be impacted in different directions. The design of the cross structure makes the outer box more flexible and less likely to be crushed or damaged. Auxiliary reinforcing rib 11 and transverse support rib 12 are fixedly connected, further enhancing the stability and support of the structure. Auxiliary reinforcing rib 11 is located on one side between diagonal reinforcing rib one 9 and diagonal reinforcing rib two 10 and is connected with transverse support rib 12, forming a solid support structure system, so that the entire outer box body 1 can better maintain stability under external force and will not be deformed or broken due to excessive impact. Transverse support rib 12 connects the two ends of diagonal reinforcing rib one 9 and diagonal reinforcing rib two 10, further increasing the compression strength and structural stability of the outer box body 1. In order to ensure that these reinforcing ribs can play the maximum role, glass fiber reinforced plastic 5 is used for manufacturing. Glass fiber reinforced plastic 5 not only has excellent strength, but also has good heat resistance and flame resistance, so it can maintain stable form in high temperature environment and will not deform or melt due to excessive heat, effectively improving the heat resistance and fire resistance of the entire packaging shell. Ensure that the outer box body 1 remains intact in high temperature or fire conditions, avoiding explosions or fires caused by excessive temperature. At the same time, the impact resistance of glass fiber reinforced plastic 5 also protects the firecrackers inside the outer box body 1 from damage when it encounters strong impact.

[0030] Working principle: When the fireproof packaging shell of the box firecracker is needed, the top corner of the outer box body 1 is provided with a top corner bumper 2, and a buffer assembly is installed inside the bumper. The core component of the buffer assembly is a slide rod 3, one end of which is fixedly connected to the inner side of the top corner bumper 2. The outer wall is provided with a spring 4. When the outer box body 1 is impacted or subjected to external force, the slide rod 3 can slide along the inside of the outer box body 1, so that the spring 4 is compressed or stretched, buffering the external impact force and reducing damage to the outer box body 1. It can also avoid excessive impact on the internal explosive material, effectively ensuring the resilience of the spring 4 and restoring the structure of the outer box body 1 in time. In addition, the inner paper layer 6 is located inside the inner wall of the outer box body 1, the paper layer 7 is located in the middle of the box body, and the surface paper layer 8 is located on the inner side of the outer box body 1, which together provides strong fireproof performance, effectively preventing the flame from spreading to the inside of the box, ensuring the fireproof function of the packaging.

[0031] In addition, the outer box body 1 is internally provided with a plurality of reinforcing rib structures, wherein the oblique reinforcing rib one 9 and the oblique reinforcing rib two 10 are arranged in a cross shape, which can significantly improve the overall strength of the box body, so that the outer box body 1 can withstand greater external impact force and pressure, in addition, the auxiliary reinforcing rib 11 is arranged on both sides of the oblique reinforcing rib one 9 and the oblique reinforcing rib two 10, and is connected with the transverse support rib 12, forming a more solid structural support system, the transverse support rib 12 connects the end of the oblique reinforcing rib one 9 and the oblique reinforcing rib two 10, further enhancing the stability and strength of the box body, all of which are made of glass fiber reinforced plastic 5, which has excellent strength, heat resistance and flame retardance, so as to effectively improve the heat resistance and fire resistance of the entire structure.

[0032] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
