Description

Technical Field

[0001] This utility model relates to the field of pyrotechnic packaging technology, specifically to an explosion-proof packaging box for pyrotechnic products. Background Technology

[0002] Pyrotechnics, also known as ignition devices, are a general term for disposable components and devices containing gunpowder or explosives that, upon external stimulation, ignite or explode to perform mechanical work. They include percussion caps, primers, ignition tubes, delay devices, detonators, detonating cords, fuses, detonating wires, as well as explosive switches, explosive bolts, starters, and cutting cords. They are commonly used to ignite gunpowder and explosives, and can also serve as small driving devices for quickly opening valves, disarming safety mechanisms, and facilitating rocket stage separation. As the most sensitive initial energy source for initiation and ignition, their initial function and sensitivity determine their position and role in weapon systems. As the most sensitive part of a weapon system, their safety and reliability directly affect the safety and reliability of the entire weapon system. They are widely used in military engineering projects such as strategic missiles, nuclear weapons, and aerospace systems. As miniaturized sensitive explosive energy sources, pyrotechnics are both the "source" for weapons and explosive systems to complete their intended functions and often the "root" of accidental explosions that could cause personal injury or death.

[0003] For safety reasons, pyrotechnics require packaging or protective treatment during transportation or storage. However, current packaging boxes for pyrotechnics have poor chemical corrosion resistance, resulting in a shorter lifespan. For example, Chinese patent CN108202901A – an explosion-proof and vibration-damping storage box – achieves shock absorption and explosion protection; however, if partial leakage occurs without an explosion, the leaked pyrotechnic is a hazardous chemical that is corrosive to the packaging box, damaging it and affecting its lifespan. Summary of the Invention

[0004] To address the problems of poor chemical corrosion resistance in packaging boxes, which shortens their service life, and the potential for explosions of some pyrotechnic items upon contact with open flames or high temperatures, posing significant safety hazards to surrounding organisms, this invention provides a specialized explosion-proof packaging box that is simple in structure, easy to manufacture, and convenient to transport.

[0005] The specific technical solution is as follows:

[0006] An explosion-proof packaging box for pyrotechnic products, the device includes a lid and a box body, the lid is fixed to the top of the box body by screws to close the box body, the box body includes an inner box body and an outer box body, and an explosion-proof component placed between the inner and outer box bodies for its buffering function;

[0007] The inner box and the outer box are a nested structure. The inner box, which is smaller in size than the outer box, is set inside the outer box. A cavity is provided between the inner box and the outer box. The cavity is a buffer cavity for housing explosion-proof components.

[0008] The explosion-proof component includes a wire mesh and a reinforcing member for mounting the wire mesh.

[0009] Furthermore, the inner box has a multi-layer structure, including an anti-corrosion layer, a waterproof layer, and an inner box body layer. The anti-corrosion layer is sprayed on the surface of the waterproof layer, and the waterproof layer is sprayed on the inner wall of the inner box body layer.

[0010] Furthermore, the wire mesh includes a side mesh and a bottom mesh, with the side mesh disposed between the inner and outer box side walls and the bottom mesh filling the buffer cavity at the bottom of the inner and outer box.

[0011] Furthermore, the side mesh and the bottom mesh are an integral structure, with the side mesh fixedly connected to the lower surface of the reinforcing member installed on the top of the box.

[0012] Furthermore, the inner and outer boxes are cylindrical structures, and the reinforcing member above the box is a circular reinforcing ring adapted to the box.

[0013] Furthermore, the wire mesh of the explosion-proof component is a multi-layered mesh structure.

[0014] Furthermore, the wire mesh is stacked in four layers, with the mesh openings arranged in a staggered manner.

[0015] Furthermore, the innermost layer of wire mesh is adhesively wrapped around the outer wall of the inner box, while the outermost layer of wire mesh is adhesively attached to the inner wall of the outer box.

[0016] Furthermore, the width of the reinforcing ring is greater than the width of the buffer cavity.

[0017] Furthermore, the reinforcing ring is welded to the box body, and the reinforcing ring has threaded holes that match the screws used to fix the box cover.

[0018] The working principle of this explosion-proof packaging box for pyrotechnics is as follows:

[0019] First, place the pyrotechnics to be transported or stored correctly in the explosion-proof packaging box of this utility model, place the box cover (1) on the box body (2), and then drill the screw (12) through the box cover (1) to form a fixing hole (11). The screw (12) and the threaded hole (2211) on the reinforcing member (221) are matched and engaged to fix the box cover (1) of the device on the box body (2) to complete the loading of the device. Then, it is transported or stored. During the transportation or storage process, if the pyrotechnics in the packaging box are damaged due to external impact or other reasons, the packaging box may be partially damaged or the life of the packaging box may be shortened, which may lead to a small amount of leakage or accidental explosion.

[0020] When a small leak occurs, the inner wall of the inner box body layer of the device is sequentially sprayed with a waterproof layer (212) of acrylic latex material and a corrosion-resistant layer (211) of PTFE. The small leak of corrosive substances can be blocked by the corrosion-resistant layer (211) of the inner box, which can reduce the damage to the packaging box that may shorten its service life or cause direct leakage that may lead to an explosion.

[0021] When an explosion occurs, the impact force generated by the explosion acts on the wire mesh (222) of the explosion-proof component (22) of the device. The wire mesh (222), with its structural characteristics and multi-layer design, can effectively buffer the energy generated by the explosion, disperse the impact force, and prevent the packaging box from exploding instantly, thereby reducing the number of concentrated pyrotechnic explosions caused by the packaging box breaking, reducing the explosion range, and minimizing the explosion hazard.

[0022] Meanwhile, the inner box (21) is composed of an anti-corrosion layer (211), a waterproof layer (212), and an inner box layer (213). The anti-corrosion layer (211) is made of PTFE anti-corrosion coating material, which has good chemical corrosion resistance. The waterproof layer (212) is made of acrylic latex material, which has a significant waterproof effect. The two together improve the anti-corrosion and waterproof performance of the inner box (21), thereby extending the service life of the inner box (21) and ensuring that it can maintain structural integrity under normal use and under certain impact, better protect the internal pyrotechnics, and work with the explosion-proof components (22) to play an explosion-proof role.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] (1) Excellent explosion-proof performance. The steel wire mesh in its explosion-proof components has four layers and is welded to the reinforcing ring at the top. When an explosion occurs, the steel wire mesh can effectively buffer the explosion impact force, disperse energy, reduce the number of concentrated pyrotechnic explosions, reduce the explosion range, greatly reduce the explosion hazards, and provide better safety protection for the surrounding environment and personnel.

[0025] (2) Excellent corrosion resistance: The inner box body is made of PTFE anti-corrosion coating material, which has good chemical corrosion resistance and can effectively resist the chemical corrosion that may be generated by pyrotechnics, protect the integrity of the internal structure of the packaging box, extend the service life of the packaging box, and ensure that it can maintain good protective performance during long-term use.

[0026] (3) Significant waterproof effect: The waterproof layer is made of acrylic latex material and is sprayed on the inner wall of the inner box layer. The waterproof effect is significant and works in conjunction with the anti-corrosion layer. This not only further enhances the anti-corrosion ability of the inner box, but also prevents moisture from corroding the pyrotechnics and packaging box, ensuring the stability and safety of the pyrotechnics during storage and transportation, so that they can reliably play a protective role under various complex environmental conditions.

[0027] (4) The structure is stable and reliable. The lid and the box body are fixedly connected by screws. The reinforcing ring is welded to the wire mesh and is matched with the screw through the thread groove. The connection between each component is tight and the overall structure is stable. It can maintain the integrity of the packaging box when subjected to a certain degree of external force impact and internal explosion impact, effectively prevent secondary hazards caused by packaging box damage, and ensure the packaging safety of pyrotechnic products.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0035] Example 1: Please refer to Figure 1-2 An explosion-proof packaging box for pyrotechnic products is provided. The packaging box of the device has a cylindrical structure and includes a lid 1 and a body 2. The lid 1 and the body 2 are fixedly connected by screws 12. The lid 1 includes a cover body and screws 12. Four screws 12 are threaded through the cover body of the lid 1 to form fixing holes 11. The screws 12 are matched with the threaded holes 2211.

[0036] Please see Figure 3-4The box 2 includes an inner box 21, an explosion-proof component 22, and an outer box 23. The diameter and height of the inner box 21 are smaller than those of the outer box 23. The inner box 21 is placed in the middle of the outer box 23, with the top of the box flush with the inner box. At this time, a buffer cavity is formed between the inner and outer boxes, and the explosion-proof component 22 is placed in the buffer cavity. Specifically, the explosion-proof component 22 is glued to the outside of the inner box 21, and the outer box 23 is glued to the outside of the explosion-proof component 22. The explosion-proof component 22 includes a reinforcing ring 221 and a wire mesh 222. The upper end of the wire mesh 222 is welded to the lower end of the reinforcing ring 221. The reinforcing ring is located at the top of the inner and outer boxes and has four evenly spaced threaded holes 2211. The upper end of the box at the lower end of the reinforcing member 221 (reinforcing ring) has the same threaded holes 2211 and is aligned with the threaded holes 2211 on the reinforcing member. The screws 12 are matched with the threaded holes 2211. The explosion-proof component 22 is glued to the outside of the inner box 21. The outer box 23 is glued to the outside of the explosion-proof component 22 and the upper end of the wire mesh 222 is attached to the outer side of the inner box 21. After the box cover 1 and the box body 2 are fixedly connected by screws 12, the wire mesh 222 will play a better role in buffering and preventing explosions, whether it is due to local damage causing a small amount of explosives to leak and explode accidentally, or other explosion-proof packaging boxes with shortened lifespans explode accidentally. It is not easy to break, reduces the number of concentrated explosives, reduces the explosion range, and minimizes the explosion hazards. The wire mesh 222 is stacked in four layers to further enhance the explosion-proof effect.

[0037] Please see Figure 5 The inner box 21 is composed of an anti-corrosion layer 211, a waterproof layer 212, and an inner box layer 213. The anti-corrosion layer 211 is sprayed on the surface of the waterproof layer 212. The anti-corrosion layer 211 is a component made of PTFE anti-corrosion coating material, which has excellent chemical corrosion resistance and improves the overall corrosion resistance of the inner box 21. The waterproof layer 212 is sprayed on the inner wall of the inner box layer 213. The waterproof layer 212 is a component made of acrylic latex material, which has a significant waterproof effect. Together with the anti-corrosion layer 211, it further improves the anti-corrosion effect of the inner box 21 and extends the service life of the inner box 21.

[0038] In summary, this utility model provides a special explosion-proof packaging box for pyrotechnics, comprising a lid 1 and a box body 2. An anti-corrosion layer 211 is sprayed onto the surface of a waterproof layer 212. The anti-corrosion layer 211 is a component made of PTFE anti-corrosion coating material, possessing excellent chemical corrosion resistance and improving the overall corrosion resistance of the inner box body 21. The waterproof layer 212 is sprayed onto the inner wall of the inner box body layer 213. The waterproof layer 212 is a component made of acrylic latex material, providing significant waterproofing. Combined with the anti-corrosion layer 211, it further enhances the anti-corrosion effect of the inner box body 21, extending its service life. The explosion-proof component 22 is glued to the outside of the inner box 21, and the outer box 23 is glued to the outside of the explosion-proof component 22. The upper end of the wire mesh 222 is welded to the lower end of the reinforcing ring 221. After the box cover 1 and the box body 2 are fixedly connected by screws 12, the wire mesh 222 will play a better role in buffering and preventing explosions, whether it is due to local damage causing a small amount of explosives to leak and explode accidentally, or other explosion-proof packaging boxes with shortened lifespans explode accidentally. It is not easy to break, reduces the number of concentrated explosives, reduces the explosion range, and minimizes the explosion hazards.
