Description

Technical Field

[0001] This invention relates to the field of packaging box technology, specifically to a universal shell packaging box with the upper and lower parts molded together. Background Technology

[0002] The weapon payload casing is a core component that houses the payload and connects the fuse. It is typically made of metal or composite materials, and its safe storage and transport directly impact the weapon's combat effectiveness. Appropriate packaging is crucial for ensuring the casing remains intact.

[0003] Currently, packaging boxes can be divided into two main categories based on molding materials: metal and non-metal. They can also be categorized by opening method: end-opening and top-and-bottom opening. Different types and structures of packaging boxes require specialized molds for molding, making mold universality impossible. Existing technologies present significant challenges: firstly, the investment in specialized molds is substantial, leading to resource waste and increased costs, resulting in poor economic efficiency; secondly, the packaging boxes have limited adaptability, failing to meet the universal storage needs of different payload shell sizes, further exacerbating costs and resource consumption.

[0004] Composite material packaging boxes are widely used. Compared with prepreg hot pressing and RTM molding, their molding method has the advantages of short processing time, high efficiency and high precision. However, existing molded packaging boxes still have not solved the problems of mold universality and poor adaptability, making it difficult to give full play to their production advantages. Summary of the Invention

[0005] (a) Technical problems to be solved In view of the above-mentioned problems, the present invention needs to provide a universal shell packaging box with the upper and lower parts being of the same mold, which can be adapted and fixed for different products.

[0006] (II) Technical Solution To address the aforementioned technical problems, this invention provides a universal shell packaging box with identical upper and lower parts, including a lid, a body, a latch, and a sealing strip. The lid and body have the same structure and are formed by pressing with the same set of molds. The lid and body serve as the upper cover and lower box body, respectively. The lid can be rotated vertically and horizontally by 180 degrees to form a packaging box body with the body. A universal mounting base plate is provided inside the box, and a detachable limiting frame is provided on the universal mounting base plate. A front pad and a rear pad are respectively provided on the front and rear sides of the limiting frame. By adjusting the selected specifications of the limiting frame and matching the front and rear pads with the appropriate internal contents, different internal contents can be fixed.

[0007] Furthermore, the lid and body are made of resin-based glass fiber reinforced composite material, manufactured using sheet molding compound through a molding process.

[0008] Furthermore, the limiting frame has various sizes and specifications. The limiting frame includes a main frame, which includes a sheet-like base plate with a C-shaped frame on the base plate. Both sides of the C-shaped frame are provided with lower silicone rubber pads. At each end of the C-shaped frame, a left limiting frame is rotatably installed on one end and a right limiting frame is rotatably installed on the other end. Both the left and right limiting frames are provided with upper silicone rubber pads.

[0009] Furthermore, the housing is provided with flanges and cover guides, and the interior of the housing is provided with internal reinforcing ribs, base plate mounting positions, and embedded round nuts. There are four base plate mounting positions for installing a universal mounting base plate.

[0010] Furthermore, the universal mounting base plate is provided with four screw holes, which correspond to four mounting positions on the base plate. Each screw hole contains a set of mounting components. The mounting components include base plate screws, with a base plate sealing gasket between the base plate screws and the housing. The base plate screws pass through the housing, the gasket, and the base plate of the limiting frame main body frame of the limiting frame. The gasket is placed between the base plate of the limiting frame main body frame and the universal mounting base plate. The limiting frame is also provided with screw holes for installing hexagonal screws.

[0011] Furthermore, two forklift buffer pads are installed on the bottom outer side of the box, and a universal mounting base plate is located above the two forklift buffer pads.

[0012] Furthermore, the front and rear pads inside the box are made of high-density expandable polystyrene and are fixed to the box body by means of their own limiting structure and structural adhesive. The front and rear pads inside the box are respectively provided with grooves, the size of which is customizable and can be adapted to the structure of the contents.

[0013] Furthermore, it also includes a grounding assembly, which includes a grounding base and a grounding post. The grounding base is fixedly installed on the enclosure, and the grounding post passes through the grounding base and the enclosure, extending into the interior of the enclosure. Two Φ4 banana sockets are also provided on the grounding base, and silicone fluoropolymer sealing rings are provided on both sides of the grounding post.

[0014] Furthermore, it also includes a balancing valve, which is located at the rear end of the housing. By using a cotter pin, the valve cap will not fall off the valve body after being loosened, thus preventing the valve cap from being lost.

[0015] Furthermore, the latch is a 304 stainless steel self-locking latch, including a latch hook, a self-locking structure, a latch seat, and a U-shaped connecting rod; the latch surface is passivated; the latch hook is installed at the latch mounting position on the lid, and the latch body is installed at the latch mounting position on the box body.

[0016] The beneficial effects of this invention compared to existing technologies are as follows: 1. By modifying the limiting frame and internal support inside the packaging box, the packaging box can provide support and protection for a series of contents. Through the combined action of the packaging box body and accessories installed inside and outside the box, the packaging box can meet the general functional requirements of lifting, forklift transportation, stacking, grounding, transportation, tethering, and sealing, and also has interchangeability and versatility. This structure of the packaging box can not only be used for the storage and transfer of a series of contents, but also reduce the investment in molds and significantly improve production efficiency; 2. This invention can achieve adaptation and fixation for different products by quickly replacing the internal support and limiting frame. The hollow sealing strip, sealing gasket, and desiccant work together to ensure a dry environment inside the box; 3. According to the model of the contents, the corresponding limiting frame is selected and then installed on a universal mounting base plate. The quick replacement of the limiting frame can be achieved without damaging the sealing structure of the box. The universal mounting base plate has also been extended to completely cover the two middle buffer pads, increasing the load-bearing capacity of the box; 4. In addition to providing circumferential support for the contents, the front and rear pads of this invention also limit and buffer the contents in the axial direction, suppressing the movement of the contents in the box and preventing damage caused by collision with the front and rear end walls; 5. This invention can meet the requirements for use such as hoisting, forklift transportation, stacking, grounding, sealing, moisture protection, and balancing air pressure. Attached Figure Description
