DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the following further details a mortar shell packaging box proposed by the present utility model in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present utility model will be clearer. It should be noted that the attached drawings are in a very simplified form and all use non-precise scales. The orientation or positional relationship indicated by terms such as "center", "lateral", "length", "width", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "side", etc. is based on the orientation or positional relationship shown in the attached drawings, rather than indicating or implying that a mortar shell packaging box or component must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation of the present utility model, and is only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present utility model. In order to make the purpose, features and advantages of the present utility model more obvious and understandable, please refer to the attached drawings.

[0025] It should be noted that the structures, proportions, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present utility model. Therefore, they do not have technical substantive significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the efficacy that the present utility model can produce and the purpose that can be achieved, should still fall within the scope covered by the technical content disclosed by the present utility model.

[0026] The following describes the specific structure of a mortar shell packaging box:

[0027] Please refer to Figures 1 to 6 , for the mortar shell packaging box of this embodiment, the packaging box includes a first shell 1, a second shell 2 and a fixing member 3. The first shell 1 is connected to the second shell 2. An internal thread 101 is provided on the inner side of the first shell 1, and an external thread 201 is provided on the outer side of the second shell 2. The internal thread 101 is matched with the external thread 201. Reinforcing ribs 5 are evenly arranged on the surfaces of the first shell 1 and the second shell 2. By providing the reinforcing ribs 5, the strength of the first shell 1 and the second shell 2 is improved.

[0028] Furthermore, a first protruding portion 102 is also provided inside the first shell 1, and a second protruding portion 202 is provided on the outer surface of the second shell 2. The first protruding portion 102 is matched with the second protruding portion 202.

[0029] The packaging box further includes a sealing ring 4. When the first shell 1 and the second shell 2 are assembled, the sealing ring 4 is arranged between the first protruding portion 102 and the second protruding portion 202 to achieve a good sealing effect.

[0030] Further, an arc surface 103 is provided inside the first housing 1. The arc surface 103 decreases in diameter from the end close to the first protrusion 102 to the end far from the first protrusion 102 to better fit the shape of the projectile.

[0031] Further, the fixing member 3 is detachably arranged inside the first housing 1, that is Figure 4 in the area below the arc surface 103 shown. The fixing member 3 includes an intermediate section 301 and an extension section 302 communicating with the intermediate section 301. The extension section 302 is annular and evenly distributed around the intermediate section 301 to fit the fins of the mortar shell. In this embodiment, six extension sections 302 are provided, and in other embodiments, other numbers may also be used. One end of the extension section 302 far from the intermediate section 301 abuts against the inner side of the first housing 1, so that the fixing member 3 can be clamped inside the first housing 1 to avoid displacement.

[0032] Further, continuous recesses 303 are provided on the surfaces of the intermediate section 301 and the extension section 302. The packaging box further includes an elastic member 6, and the elastic member 6 is arranged in the recesses 303. When the mortar shell is placed in the fixing member 3, the elastic member 6 can play a good shock-absorbing role for the fins, reducing the phenomenon of damage. In other embodiments, the recesses 303 may also be provided on the sides of the intermediate section 301 and the extension section 302 to place the elastic member 6 for protection.

[0033] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0034] The above embodiments only represent several implementation manners of the present invention.
