In field blasting operations, optical instruments, unmanned aerial vehicles, precision instruments, ammunition, and pyrotechnic devices are usually used. The packaging boxes for these items are single-preservation wooden or plastic boxes. After unpacking and using them in field operations, when they are repacked and stored, the protective performance of the packaging boxes after repeated use is low, and the sealing effect is not good. The sealing openings are easily eroded, causing internal moisture and rainwater to invade. The shock absorption level inside the box is not high, and the safety protection ability for ammunition during transportation and storage is insufficient, making the types of ammunition protected by a single box group relatively single and the simplicity not high. Content of the Utility Model

[0003] In view of the deficiencies of the prior art, the purpose of the utility model is to provide a multifunctional protective box to solve the problem of weak protective function of the protective box in the prior art.

[0004] To solve the above problems, the utility model provides a multifunctional protective box, which includes a lining body, an inner cover, an outer box body, an outer cover, and an airbag protection component connected to the outer box body. The lining body and the inner cover are arranged inside the outer box body. A protective layer is connected inside the lining body, and the outer cover is connected to the top of the outer box body.

[0005] Wherein, a first opening that is recessed downward is formed at the top of the lining body, a second opening that is recessed downward is formed at the end of the inner cover. A first protrusion is formed at the end of the first opening, a second protrusion is formed at the end of the second opening. The sides of the first protrusion and the second protrusion are in contact with each other, so that a sealing groove is formed between the first opening and the second opening, and a sealing strip is connected in the sealing groove. An inner groove is opened at the lower part of the lining body where the first protrusion is located, the protective layer is arranged in the inner groove, and the top of the protective layer abuts against the first protrusion and the second protrusion.

[0006] Preferably, the airbag protection component includes an airbag and a gas storage cylinder connected to the airbag. A deflation valve is arranged between the airbag and the gas storage cylinder. The airbag is embedded on the outer wall of the outer box body, and the gas storage cylinder is connected to the outer wall of the outer box body.

[0007] Preferably, side grooves are arranged on the outer wall of the outer box body, and the airbag is connected in the side grooves.

[0008] Preferably, a cover plate is provided on the outer box wall of the outer box body at the position of the side groove, and the cover plate is hinged on the outer box wall of the outer box body.

[0009] Preferably, a convex block is formed on the cover plate, and a clamping groove is formed on the outer box wall of the outer box body, and the convex block is clamped in the clamping groove.

[0010] Preferably, a pull rope is connected to the bottle cap of the gas storage cylinder, and a groove is formed on the top of the outer cover, and the pull rope can be converged in the groove.

[0012] Preferably, the first opening and the second opening are quarter-circular openings, so that the sealing groove formed between the first opening and the second opening is semi-circular.

[0013] Preferably, the sealing strip includes a sealing strip body and a semi-circular protrusion connected to the sealing strip body. The semi-circular protrusion is connected in the sealing groove, and the sealing strip body is connected to the inner liner and the inner cover.

[0014] The multifunctional protection box provided by the present utility model has the following beneficial effects:

[0015] 1. Compared with the prior art that only uses a single wooden or plastic box, in the protection box provided by the present utility model, the outer box body forms a primary protection, the inner liner forms a secondary protection, and the protective layer forms a tertiary protection. Among them, the inner liner, as the secondary protection, can be a rubber inner liner to enhance the shock absorption effect of the box body; the protective layer, as the tertiary protection, can play a role in shock absorption and cold protection. For example, the protective layer is made of EPS (polystyrene foam) or EPO (expandable polyethylene, styrene polymer) or EPP (foamed polypropylene), etc., which enhances the shock absorption and cold protection effect of the protection box.

[0016] 2. The sealing of the protection box is optimized.

The following is a description of the embodiments of the present invention based on its overall structure.

[0027] See also Figure 1 and Figure 4 A multifunctional protective box comprises an inner lining 1, an inner cover 2, an outer box 3 and an outer cover 4, and an airbag protection assembly 5 connected to the outer box 3. The inner lining 1 and the inner cover 2 are arranged inside the outer box 3, a protective layer 8 is connected to the inner wall of the inner lining 1, and the outer cover 4 is connected to the top of the outer box 3.

[0028] See also Figure 1 and Figure 4 , wherein a first opening 11 which is recessed downward is formed at the top of the lining body 1, so that a first protrusion 110 is formed at the bottom of the first opening 11, and a second opening 21 which is recessed downward is formed on the extension of the inner cover 2, so that a second protrusion 210 is formed at the bottom of the second opening 21, and the sides of the first protrusion 110 and the second protrusion 210 are in contact with each other, so that a sealing groove 6 is formed between the first opening 11 and the second opening 21, and a sealing strip 7 is connected to the sealing groove 6; an inner groove 12 is formed on the inner wall of the lining body 1 at the lower part of the first protrusion 110, and the protective layer 8 is arranged in the inner groove 12, and the top of the protective layer 8 is in contact with the first protrusion 110 and the second protrusion 210.

[0029] See also Figure 1 and Figure 4, specifically, in the multifunctional protection box of the above embodiments, a second protrusion 210 extending outward in a circle is formed at the end of the inner cover 2, so that a second opening 21 is formed between the upper surface of the second protrusion 210 and the top of the inner cover 2.

[0030] Refer to Figure 1 and Figure 4 , on the side of the inner liner 1 away from the outer box body 3, a first opening 11 that is recessed downward in a circle is formed at the top. An inner groove 12 is further formed at the end of the first opening 11, so that a first protrusion 110 is formed between the upper end wall of the inner groove 12 and the bottom of the first opening 11.

[0031] Refer to Figure 1 and Figure 4 , connect the protective layer 8 in the inner groove 12, and the width value of the protective layer 8 should be greater than the depth value of the inner groove 12, so that the protective layer 8 can contact the second protrusion 210, thereby playing a supporting role for the inner cover 2. And the contact part between the first protrusion 110 on the inner liner 1 and the second protrusion 210 on the inner cover 2 is exactly at the top position of the protective layer 8. As long as this part is sealed, the inner liner 1 can be sealed. Therefore, the sealing strip 7 is used to seal this part.

[0032] Refer to Figure 1 and Figure 4 , in this embodiment, the sealing groove 6 formed between the first opening 11 and the second opening 21 is a square sealing groove, so the sealing strip 7 is a square sealing strip. The sealing strip 7 uses a sealing rubber strip, especially a high-density rubber pad, so the sealing effect is better.

[0033] Refer to Figure 3 , in another preferred embodiment, the first opening 11 that is recessed downward formed at the top of the inner liner 1 is a quarter-circular opening, and the second opening 21 that is recessed downward formed at the top of the inner cover 2 is also a quarter-circular opening, so that the sealing groove 6 formed between the first opening 11 and the second opening 21 is semi-circular, that is Figure 3The semicircular sealing groove 61 shown in . Similarly, an inner groove 12 is formed on one side of the quarter-circular opening of the lining body 1, in which the protective layer 8 is still arranged, the protective layer 8 still supports the inner cover 2, and the contact position between the lining body 1 and the inner cover 2 is still located on the top of the protective layer 8. At this time, the sealing strip 7 configured therewith is used to seal the semicircular sealing groove 61. At this time, the sealing strip used is a sealing strip of the following structure: the sealing strip 7 includes a sealing strip body 71 and a semicircular protrusion 72 connected to the sealing strip body 71, and the semicircular protrusion 72 is connected to the semicircular sealing groove 61. When sealing, the semicircular protrusion 72 on the sealing strip 7 is directly stuck in the semicircular protrusion 72, and the sealing strip bodies 71 on both sides of the semicircular protrusion 72 are respectively connected to the upper surfaces of the lining body 1 and the inner cover 2. Compared with the square sealing groove, this method has a better sealing effect.

[0034] See also Figure 3 In another preferred embodiment, the sealing strip 7 is equipped with a special cutter for removing the sealing strip 7 from the sealing groove. As some optional embodiments, the sealing strip 7 is configured as segments, that is, not a whole sealing strip, which is convenient for removing the sealing strip. The sealing strip 7 can be reused to avoid environmental pollution.

[0035] See also Figure 3 In a preferred embodiment, a semicircular groove 720 is provided on the semicircular protrusion 72 on the sealing strip 7. The semicircular groove 720 is provided at one end away from the sealing surface of the semicircular protrusion 72 and is used to peel off the sealing strip 7. A special tool is configured according to the semicircular groove 720. For example, when the sealing strip 7 is segmented or a whole strip, the tool is inserted into the semicircular groove 720, and then the tool is used to pry the tool inserted into the semicircular groove 720 upward, so that the sealing strip 7 is subjected to an upward force and leaves the semicircular sealing groove 61. In this way, the sealing strip 7 can be reused.

[0036] Furthermore, the protective layer 8 is made of EPS polystyrene foam or EPO expandable polyethylene, styrene polymer or EPP (expanded polypropylene) or polyethylene foam plastic EPE or polyurethane foam plastic EPU, etc., and the protective layer formed by the production has the function of shock absorption and buffering. The protective layer 8 not only has shock absorption and buffering, but also has a cold-proof effect, and can be used for blasting operations in plateaus and low-altitude areas with low temperatures all year round. It can insulate the ammunition and related pyrotechnics in the box to a certain extent, so that they will not be frozen, play a role in cold resistance, and is conducive to the development of blasting operations.

[0037] See also Figure 2, In a preferred embodiment, the airbag protection assembly 5 includes an airbag 51 and a gas cylinder 52 connected to the airbag 51. A deflation valve 53 is provided between the airbag 51 and the gas cylinder 52. The airbag 51 is embedded in the outer wall of the outer box body 3, and the gas cylinder 52 is connected to the outer wall of the outer box body 3.

[0038] Refer to Figure 2 , Specifically, the gas cylinder 52 can inflate the airbag 51 to make the airbag 51 expand, so as to surround the outer wall of the outer box body 3, playing a buffering role for the multi-functional protection box, enabling the multi-functional protection box to be used in airdrop transportation. Through airdrop, the transportation of optical instruments, drones, precision instruments, ammunition, and pyrotechnics can be realized. The airbag 51 with strain flexibility during landing can greatly reduce the landing impact. The deflation valve 53 provided at the connection between the airbag 51 and the gas cylinder 52 squeezes the airbag when the multi-functional protection box lands. When the air pressure reaches the rated air pressure of the deflation valve 53, the deflation valve 53 automatically exhausts air to reduce the landing bounce effect of the multi-functional protection box.

[0039] In addition, after the airbag 51 is inflated, it can be made into a floating raft in case of emergency, enabling the protection box to be widely used in rescue activities such as earthquake relief and flood relief. Among them, the deflation valve can be a safety valve with a spring. The working principle of the safety valve is mainly based on the interaction between the pre-tightening force of the spring and the medium pressure. The safety valve controls the discharge of the medium by automatically opening and closing, so that the system pressure is always kept within the safe range. Therefore, the deflation valve plays a role in preventing the multi-functional protection box from bouncing after landing.

[0040] Furthermore, the main body of the airbag 51 is made of a composite material, which is composed of a load-bearing layer and an airtight layer. The load-bearing layer mainly bears all the strength of the airbag body and is made of a PA nano-composite material. The airtight layer is formed by silicone. Silicone is used for the coating of the airbag fabric. It has high environmental stability, and the airbag with a silicone coating can be recycled, and it is not necessary to spend much cost to recycle nylon.

[0041] Refer to Figure 2 , Further, a pull rope is connected to the bottle cap of the gas cylinder 52, and a groove 41 is formed on the top of the outer cover 4. The pull rope can be gathered in the groove 41. Among them, the connection relationship between the gas cylinder 52, the airbag 51, and the pull rope belongs to the prior art and will not be specifically described here. When in use, directly pull the pull rope of the gas cylinder 52 to deflate, and thus the airbag 51 can be inflated.

[0042] Refer to Figure 2, Further, side grooves 31 are provided on the outer box wall of the outer box body 3, and the airbag 51 is connected in the side grooves 31. A cover plate 9 is provided at the position of the side grooves 31 on the outer box wall of the outer box body 3, and the cover plate 9 is hinged on the outer box wall of the outer box body 3. A convex block 91 is formed on the cover plate 9, and a clamping groove 32 is formed on the outer box wall of the outer box body 3, and the convex block 91 is clamped in the clamping groove 32.

[0043] Specifically, the cover plate 9 is hinged on the outer box wall of the outer box body 3 and fixed on the outer box body 3 through the convex block 91. When the airbag 51 in the side groove 31 is inflated and expanded, it can push open the cover plate 9, so that the convex block 91 on the cover plate 9 is pulled out of the clamping groove 32, and then the expanded airbag 51 surrounds the outer box wall of the outer box body 3. The function of the cover plate 9 is to protect the airbag 51. And the airbag 51 is arranged in the side groove 31, so that the replacement of the airbag 51 can be completed quickly.

[0044] Refer to Figure 2 , Further, a channel 33 is formed on the outer box body 3, and the air pipe between the airbag 51 and the gas storage cylinder 52 can be arranged in the channel 33. The channel 33 can play a role in protecting the air pipe.

[0045] In this embodiment, only the airbag protection assembly 5 is exemplarily described. According to the above description, many changes and variations can be made. For example, multiple airbags can be provided on the multifunctional protection box, and airbags are provided on each surface of the multifunctional protection box, and each airbag is configured with a gas storage cylinder, so that each surface of the multifunctional protection box can play a protective role. Another example is that according to the size of the multifunctional protection box, two airbags can be provided on each surface to play a protective role.

[0046] In summary, the protection box provided by the present utility model has a multi-level protection function, can be used for transporting and storing various related instruments and ammunition in blasting operations, and plays roles such as shock absorption, moisture protection, and cold resistance. Moreover, the above protection box can not only be used in blasting operations, but also can be used in rescue activities such as earthquake relief and flood relief.

[0047] The foregoing description of specific exemplary embodiments of the present utility model is for purposes of illustration and exemplification. These descriptions are not intended to limit the present utility model to the precise forms disclosed, and it is obvious that many changes and variations can be made in accordance with the above teachings. Although embodiments of the present utility model have been shown and described, the specific embodiments are merely interpretations of the present utility model and not limitations thereof.
