[0002] Artillery shells are ammunition fired from artillery. They convert the chemical energy of the propellant into kinetic energy, ultimately destroying, injuring, or engaging in other tactical purposes. They typically consist of a projectile, a cartridge (or bag), propellant, and a fuse. Artillery shells are dangerous explosives, and roto-molded boxes provide a safe place for them.

[0003] The artillery shells were unloaded and transported to the artillery positions. First, the soldiers carefully untied the ropes and buckles securing the roto-molded boxes. These boxes were tightly packed inside the carriage. Thanks to their sturdy and regular design, they remained intact and undamaged even during the bumpy road.

[0004] However, in the existing technology, some new roto-molding boxes for artillery shells may encounter the problem of loose sealing contact surfaces when sealing the artillery shells, resulting in external impurities such as water vapor, sand and dust easily invading the box during storage and transportation of the artillery shells, affecting the charging performance of the artillery shells. Key components such as the fuse may also malfunction due to moisture or dust, thereby reducing the reliability and safety of the artillery shells. Therefore, in response to the above shortcomings, a new roto-molding box for artillery shells is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a new type of artillery shell rotational molding box, which aims to improve the problem that some new type of artillery shell rotational molding boxes in the prior art may cause artillery shell malfunction and reduce safety during use due to inadequate sealing.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figures 1 to 3 The present invention provides an embodiment of a novel roto-molded shell box, comprising a shell body 1, which is the main body of the entire roto-molded shell box and is manufactured through a corrosion-resistant roto-molding process. Two sealing mechanisms are fixedly connected to the right side of the shell body 1, which can effectively prevent external impurities such as dust and moisture from entering the shell body 1, thereby protecting the quality and safety of the shells.

[0026] The sealing mechanism includes two threaded tubes 2. The left sides of the two threaded tubes 2 are fixedly connected to the right side of the box body 1. Through the welding process, the connection between the threaded tubes 2 and the box body 1 is firm and stable. The outer sliding connection of the threaded tube 2 is provided with a sealing ring 3. The sealing ring 3 is made of rubber material. The sliding installation method of the sealing ring 3 on the threaded tube 2 is convenient and quick, and it can fit tightly when threadedly connected with the plastic cover 5 to form a seal. The inner sliding connection of the threaded tube 2 is provided with a PP foam 4. The PP foam 4 has good buffering properties. When the plastic cover 5 is tightened, it can further fill the internal space of the threaded tube 2, thereby enhancing the sealing effect and providing a certain buffering protection for the shells. The right side of the PP foam 4 is in contact with the inner right side of the plastic cover 5. The outer sliding connection of the threaded tube 2 is connected to the inside of the plastic cover 5. The plastic cover 5 is made of a plastic material that matches the box body 1. Through the threaded connection with the threaded tube 2, the sealing and opening operations of the box body 1 can be easily realized. During transportation or storage, as long as the plastic cover 5 is tightened, the sealing performance of the sealing mechanism can be ensured.

[0027] The fixing mechanism includes a metal bracket 6, the exterior of which slides onto the inner wall of the bottom end of the box 1, providing support and fixation. Concave brackets 7 are fixedly attached to the left and right ends of the bottom side of the metal bracket 6, effectively wrapping and supporting the bottom sides of the box 1. Reinforcement plates 9 are fixedly attached to the front and rear ends of the concave brackets 7, the exteriors of which slide onto the left and right ends of the box 1, respectively. The reinforcement plates 9 enhance the structural strength and stability of the concave brackets 7. C-shaped rings 8 are fixedly attached to the opposite sides of the reinforcement plates 9, each of which is rotatably connected to a triangular ring 10. The C-ring 8 provides a connection base for the triangular ring 10 to rotate. The triangular ring 10 rotates flexibly on the C-ring 8, allowing for adjustment of angles during handling or transportation, facilitating integration with other handling equipment or fixing devices. Screws 11 are threaded onto the left and right ends of the reinforcement plates 9, tightly connecting the reinforcement plates 9 to the concave bracket 7 and the box 1. The outer ends of multiple screws 11 are respectively threaded into the front and rear inner walls of the concave bracket 7, and the outer ends of multiple screws 11 are respectively threaded into the left and right inner walls of the box body 1. The tightening action of screws 11 ensures the overall structure of the fixing mechanism is stable and reliable. The adjacent sides of the multiple concave brackets 7 are in contact with the front and rear sides of the box body 1, ensuring that the metal bracket 6 and the concave bracket 7 stably support and fix the box body 1.

[0028] Working principle: First, insert the shell into the box body 1, then align the plastic cover 5 with the threaded tube 2 and screw it in. As the plastic cover 5 is screwed in, its interior gradually fits tightly with the exterior of the threaded tube 2, while squeezing the sealing ring 3 located on the exterior of the threaded tube 2, causing the sealing ring 3 to elastically deform and fill the tiny gap between the threaded tube 2 and the plastic cover 5, thereby forming a reliable seal and preventing the entry of external impurities such as dust and moisture. The PP foam 4 located inside the threaded tube 2 is further compressed into the space between the threaded tube 2 and the right side of the plastic cover 5 during the tightening process of the plastic cover 5. On the one hand, this enhances the sealing effect, and on the other hand, its own buffering properties can absorb the impact force that may be transmitted to the shell, protecting the shell from damage.

[0029] Then, two metal brackets 6 are clamped on both ends of the box body 1, and the concave frame 7 is used to wrap and support the bottom of the box body 1. Then, screws 11 are used to tightly connect the reinforcement plate 9 to the concave frame 7 and the box body 1, respectively, so that the entire fixing mechanism forms a stable whole. The rotational connection design between the C-shaped ring 8 on the reinforcement plate 9 and the triangular ring 10 allows the triangular ring 10 to be flexibly adjusted in angle, so that it can better connect with other equipment or fixing devices during handling or transportation.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
