DETAILED DESCRIPTION

[0032] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0033] Example 1

[0034] A specific embodiment of the present utility model discloses a packaging box for explosive items, such as Figure 1 As shown, it includes a box assembly 1, a placement slot 3 and a limit assembly 4. The box assembly 1 has an internal cavity. The placement slot 3 is arranged in the internal cavity for placing explosive items. The limit assembly 4 is connected to the placement slot 3 to limit the position of the explosive items.

[0035] The box assembly 1 forms a cavity inside the box through the cooperation of the box cover and the box body, so that explosive items can be placed in the cavity inside the box.

[0036] Exemplarily, the packaging box for explosive items further includes a connecting assembly 2, wherein the box lid is hingedly connected to the box body at one end and connected to the other end via the connecting assembly 2. The connecting assembly 2 includes a first connecting member 21 and a second connecting member 22. The first connecting member 21 is disposed on the box body, and the second connecting member 22 is disposed on the box lid. The first connecting member 21 and the second connecting member 22 cooperate to secure the connection between the box lid and the box body. Exemplarily, the first connecting member 21 is a buckle, and the second connecting member 22 is a slot.

[0037] For example, the box cover and the box body can also be designed as a split type, so that explosive items can be placed in the cavity inside the box. When the box cover and the box body are designed as a split type.

[0038] Further, if Figure 2 As shown, the box assembly 1 is provided with a vibration-damping layer 11 on one side of the box cavity and a flame-retardant layer 12 on the other side. Vibration-damping layer 11 is made of an elastic material and can provide a vibration-damping effect on explosive items in the box cavity; flame-retardant layer 12 is made of a flame-retardant material and can prevent the explosive items in the box cavity from exploding, causing the box assembly 1 to burn and posing a danger to surrounding items.

[0039] Exemplarily, the vibration-damping layer 11 is made of rubber.

[0040] A one-way valve 13 is also provided on the box assembly 1. The one-way valve 13 can prevent external gas from entering the cavity inside the box. The one-way valve 13 can also cooperate with a vacuum machine to extract the gas in the cavity inside the box through the vacuum machine to keep the cavity inside the box in a vacuum state.

[0041] Preferably, the box assembly 1 further includes a sealing layer. When the box assembly 1 is in a closed state, the sealing layer can keep the cavity inside the box in a sealed state.

[0042] Preferably, Figure 1 As shown, the packaging box for explosive items further includes a temperature and pressure alarm 5, which is disposed on the box assembly 1. The temperature and pressure alarm 5 can monitor the temperature and pressure within the cavity within the box. When the temperature and pressure within the cavity within the box become abnormal, the temperature and pressure alarm 5 can sound an alarm, thereby alerting staff to take appropriate measures. The temperature and pressure alarm 5 is prior art and will not be described in detail here.

[0043] like Figure 1 and Figure 3 As shown, the storage tank 3 includes a storage frame 31 and a tank bottom 32. The storage frame 31 is connected to the vibration-damping layer 11. One end of the tank bottom 32 is connected to the storage frame 31, and the other end is connected to the vibration-damping layer 11 located at the bottom of the box. The storage frame 31 is connected to the limiting assembly 4. The storage frame 31 has a cavity structure, and the cavity of the storage frame 31 is used to hold the flame-retardant liquid. The storage frame 31 is provided with a thermal valve 311. The thermal valve 311 is located on the side where the storage frame 31 is connected to the limiting assembly 4. The thermal valve 311 is used to seal the cavity of the storage frame 311 to prevent the flame-retardant liquid from flowing out. When the temperature of the explosive material rises abnormally, the thermal valve 311 melts, allowing the flame-retardant liquid to flow out, cooling the explosive material and preventing it from burning or exploding. This reduces the threat posed by the explosive material to the surrounding environment and improves safety.

[0044] Preferably, there are multiple thermal valves 311. When the temperature of the explosive article rises abnormally, the thermal valves 311 melt, facilitating the rapid outflow of the flame retardant liquid.

[0045] Exemplarily, the thermal valve 311 is made of materials such as polyimide or lead-containing solder alloy. When the temperature in the placement tank 3 is higher than 250° C., the thermal valve 311 melts, causing the flame retardant liquid to flow out and cool the explosive items.

[0046] Exemplarily, the flame retardant liquid is water.

[0047] Exemplarily, the flame retardant liquid is a silicone oil flame retardant.

[0048] like Figure 1 and Figure 3 As shown, the limiting assembly 4 is provided in plurality, and the limiting assembly 4 includes a limiting block 41 and a spring 42. The limiting block 41 is connected to the placement frame 31 through the spring 42. When explosive items need to be placed, the explosive items squeeze the limiting block 41, so that the spring 42 is in a compressed state. The limiting block 41 fixes the explosive items under the elastic force of the spring 42 to prevent the explosive items from moving.

[0049] Example 2

[0050] Another specific embodiment of the present invention discloses a packaging box for explosive items, such as Figure 4As shown, the difference from Example 1 is that the box assembly 1 further includes a partition 14. Multiple placement slots 3 are provided within the cavity of the box. The partition 14 is connected to adjacent placement frames 31, separating adjacent placement slots 3. The partition 14 is made of a liquid-isolating and heat-insulating material. If the explosive items in a placement slot 3 within the same cavity of the box are abnormally heated, causing the flame-retardant liquid in that placement slot 3 to leak out, the partition 14 prevents the flame-retardant liquid from flowing into other placement slots 3 and damaging the explosive items therein.

[0051] Preferably, Figure 4 As shown, the bottom 32 of the tank is a cavity structure, and a leakage hole 321 is set on the side of the bottom 32 where the explosive items are placed. The liquid in the placement tank 3 can enter the bottom 32 of the tank through the leakage hole 321, preventing the flame retardant liquid level in the placement tank 3 from being too high and crossing the partition 14 into other placement tanks 3.

[0052] Preferably, a moisture-absorbing bag is placed in the bottom 32 of the tank to keep the storage tank 3 dry when the explosive items are in a normal storage state.

[0053] Compared with the prior art, the packaging box for explosive items of the present invention effectively fixes the explosive items by providing a placement slot 3 and a limit assembly 4, preventing the explosive items from being displaced and causing bumps or damage; by providing a vibration-damping layer 11 and a flame-retardant layer 12 on the box assembly 1, the explosive items in the cavity of the box can be damped and flame-retarded, preventing the explosive items in the cavity of the box from exploding and causing the box assembly 1 to burn, thereby causing danger to surrounding items; by providing a one-way valve 13 and a temperature and pressure alarm 5, external gas can be prevented from entering the cavity of the box, and the temperature and pressure in the cavity of the box can be monitored. When the temperature and pressure in the cavity of the box are abnormal, an alarm can be issued to remind staff to deal with it; by providing multiple placement slots 3, the packaging box for explosive items can be improved so that more explosive items can be placed, saving material use and optimizing space utilization; the provision of a partition 14 and a leakage hole 321 can prevent the flame-retardant liquid from flowing to other placement slots 3 and damaging the explosive items in other placement slots 3, thereby reducing losses and improving economic benefits.

[0054] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
