Abstract
Description
Technical Field
[0001] The utility model relates to an airtight packaging box, in particular to a solid reinforced rib end-open type missile airtight packaging box. Background Art
[0002] At present, missiles and other dangerous explosive items are stored in end-opening airtight packaging boxes, which are usually manufactured by rotational molding. Their structure is mainly composed of a box body and a box cover. In order to increase the strength of the box body, reinforcing ribs are also provided on the outer surface of the box body. However, the reinforcing ribs of traditional rotational molding boxes are hollow structures, that is, the outer wall of the box body is directly raised to form reinforcing ribs, and these reinforcing ribs are only extended on the outer surface of the box body, so they can only play a reinforcing role in a certain direction of the outer surface of the box body, but cannot form an integrated reinforcement of a grid-like arrangement on the entire outer surface of the box. At the same time, the larger area of the outer surface of the box body will be reinforced, but the smaller area of the outer surface of the box body, such as the top of the box body, will be strengthened. The chamfered surfaces arranged between the surface and the two side surfaces of the box are usually not designed, which will lead to a lack of structural strength at the chamfered surfaces, thereby affecting the overall structural strength of the box; and the support at the bottom of the box is usually only point-supported or column-supported at the four corners and the middle of the box. The supporting force in actual use is not balanced and stable enough, causing local collapse and deformation of the box; obviously, due to the existence of the above-mentioned structural defects, the structural strength of the box will inevitably be insufficient as the volume of the box increases; in addition, the box is a single-layer rotationally molded box with cushioning material stuffed inside to ensure the cushioning of the built-in items. This still cannot have sufficient cushioning capacity when subjected to a large external impact, and therefore cannot provide greater protection for the items stored inside. Utility Model Content

[0029] A solid reinforced rib end-open missile airtight packaging box, such as Figure 8~Figure 11 As shown, it relates to an airtight packaging box for storing dangerous explosive items such as missiles, and its structure mainly includes a box body 1 and a box cover 2. The box body 1 is a horizontally placed long rectangular box body. At one axial end of the box body 1, that is, Figure 1 The left end of the box body 1 is provided with a closed end face, and the end face is integrally rotationally molded with the box body 1. The other axial end of the box body 1, that is, Figure 1 The right end of the box body 1 is provided with an open box opening to facilitate the loading of dangerous explosive items such as missiles, and the box cover 2 is used to seal the box opening.
[0030] The bottom surface of the box body 1 is provided with a plurality of solid support blocks 17 arranged in sequence along the axial direction. Each solid support block is a rectangular block with a relatively large area, and both sides of each solid support block 17 extend to the two side surfaces of the box body 1 respectively.
[0031] The top surface, both side surfaces, end surface and bottom surface of each solid support block 17 of the box body 1 are provided with a plurality of solid transverse ribs 14 parallel to each other and extending horizontally, a plurality of solid longitudinal ribs 15 parallel to each other and connected to form a vertical cross with the plurality of solid transverse ribs 14, and a plurality of reinforcing grooves 16 separated by the plurality of solid transverse ribs 14 and solid longitudinal ribs 15 connected to form a vertical cross, wherein the reinforcing grooves 16 are all four-sided pyramid-shaped grooves with a large mouth and a small bottom, and the solid transverse ribs 14 and solid longitudinal ribs 15 separating the reinforcing grooves 16 are all ridge-shaped ribs with a small top and a large bottom.
[0032] A chamfered surface 18 is provided between the top surface of the box body 1 and the two side surfaces of the box body 1. A plurality of reinforcing grooves 16 are provided on the chamfered surface 18 at equal intervals along the axial direction. The reinforcing grooves 16 are triangular pyramid-shaped grooves with a large mouth and a small bottom.
[0033] In this way, through a plurality of solid transverse ribs 14 and solid longitudinal ribs 15 connected together in a vertical cross pattern, and a plurality of reinforcing grooves 16 separated thereby, combined with a plurality of reinforcing grooves 16 arranged on the chamfered surface 18, an integrated reinforcement structure arranged in a grid shape can be formed on the outer surface of the box body 1.
[0034] The inner surface of the box body 1 is provided with an interlayer 7 and a cushioning material filled in the interlayer, and the cushioning material is usually a PU filled foam material.
[0035] The structural design of the interlayer 7 in combination with the solid support block 17 can not only further improve the structural strength of the box body 1, but the solid support block 17 can also provide a more balanced and stable supporting force for the box body 1, thereby avoiding local collapse and deformation of the box body 1 during support. The design of the interlayer 7 in combination with the buffer material can play the role of double-layer protection and buffering. Even if the box body 1 is subjected to a large external impact, it can still have sufficient buffering capacity, thereby providing greater protection for the items stored inside.
[0036] Moreover, the box body 1, the solid transverse ribs 14, the solid longitudinal ribs 15, the reinforcing grooves 16, the solid support blocks 17 and the interlayer 7 are integrally rotationally molded, which can simplify the production process and improve the production efficiency.
[0037] In addition, two dividing grooves 6 are provided on the outer surface of the box body 1 , each of which is an annular groove extending radially around the box body 1 .

[0039] The bottom surfaces of the left section and the right section are completely covered by a solid support block 17, which can provide greater supporting force, and the number of solid support blocks 17 on the bottom surface of the middle section is designed according to the length of the middle section. When the number exceeds two, these solid support blocks 17 will be arranged equidistantly along the axial direction, and a number of reinforcement grooves 16 are provided between each two adjacent solid support blocks 17. The several reinforcement grooves are respectively located on both sides of the bottom surface of the middle section to provide bottom support strength, and the reinforcement groove 16 is also a triangular pyramid-shaped groove with a large mouth and a small bottom.

This embodiment adopts two parallel solid top ribs 1, and the two ends of each solid top rib extend to the two sides of the box body 1 respectively, and are used to provide structural strength for the top of the box body 1. In fact, it is also to provide support strength when the lifting ring 3 lifts the entire airtight packaging box.
[0041] The outer surface of the box cover 2 is also provided with a plurality of solid transverse ribs 14 parallel to each other and extending horizontally, a plurality of solid longitudinal ribs 15 parallel to each other and connected to form a vertical cross with the plurality of solid transverse ribs 14, and a plurality of reinforcing grooves 16 separated by the plurality of solid transverse ribs 14 and solid longitudinal ribs 15 connected to form a vertical cross, each reinforcing groove 16 is a four-sided pyramid-shaped groove with a large mouth and a small bottom, and the design structure of the outer surface of the box cover 2 is actually exactly the same as the structural design of the end face of the box body 1.
[0042] A sealing rib 19 and a sealing groove 21 are respectively provided between the contact end surfaces of the box opening and the box cover 2. The sealing rib 19 and the sealing groove 21 are usually arranged in a rectangular ring around the box opening, and the sealing rib 19 is fitted and embedded in the sealing groove 21 to form a sealing cover of the box opening by the box cover 2. A sealing ring is usually embedded in the sealing groove 21 to enhance the sealing performance.
[0043] The box cover 2 and the box body 1 are provided with hinges 4 connected to each other and quick clamps 5 for detachable connection and locking. The hinges 4 only need to be arranged on one of the sides of the box cover 2 and the box body 1, and the number of hinges 4 can be selected according to the size of the side. For example, two hinges are designed in this embodiment, and the box cover 2 can open and close the box opening on one side through the two hinges 4.
[0044] The quick clamps 5 can be designed to be multiple in radial direction, that is, the top surface, both side surfaces and bottom surface of the box cover 2 and the box body 1 are all provided with multiple quick clamps 5, so that the box cover 2 can seal the box opening and form a lock through the multiple quick clamps 5.
[0045] In addition, a hinge installation groove 41 for installing the hinge 4 and a clamp installation groove 51 for installing the quick clamp 5 are provided between the box cover 2 and the box body 1, which can hide the installed hinge 4 and quick clamp 5 to avoid accidental collision damage.
