Description

Technical Field

[0001] The utility model relates to the technical field of foam boxes, and particularly relates to a foam box with good impact resistance. Background Technique

[0002] A foam box is a box-type packaging container made of foam plastic. Foam plastic is a plastic with many tiny air holes inside. Foam boxes are often used in the transportation of fruits and the packaging of items and are excellent packaging materials. For example, products such as televisions, refrigerators, washing machines, air conditioners, electronic instruments, precision instruments, glassware, ceramic products, and art crafts all require EPS foam parts as cushioning packaging materials. EPS foam plastic is based on polystyrene resin and is an indispensable container for heat preservation and freshness preservation materials in aspects such as seafood freezing, vegetable freshness preservation, insulation boxes, cold storages, refrigerated trucks, and railway passenger cars. EPS packaging products are relatively easy to recycle and reuse and are good green packaging materials.

[0003] For example, the Chinese patent with the publication number CN217295500U proposes a foam box with good impact resistance. The assembly generally includes a box body. A first handle is arranged at the upper end of the box body, and two second handles are symmetrically arranged on both sides of the box body. Second protective layers are arranged on the outer sides of the first buffer plate and the second buffer plate, a first protective layer is arranged on the outer wall of the box body, and four second fixing blocks are evenly arranged at the bottom end of the box body. In the utility model, the device realizes the anti-impact and buffering effects on the side of the foam box through the first spring and the second spring structures. The device is convenient to lift the whole device and open the box cover through the first handle structure and the second handle structure. Second protective layer structures are arranged on the outer sides of the first buffer plate and the second buffer plate around the device, and the box body can realize the protection of the device through the first protective layer structure and the second protective layer structure. However, in this scheme, multiple layers of protection are adopted, which easily leads to the excessive thickness of the foam box, and multiple buffer plates are used for buffering, and the buffering effect is average. Therefore, we propose a foam box with good impact resistance. Summary of the Utility Model

[0004] Aiming at the problems mentioned in the background technique, the purpose of the utility model is to provide a foam box with good impact resistance to solve the problems mentioned in the background technique.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] A foam box with good impact resistance includes: a foam box outer shell, an installation groove is opened on the top surface of the foam box outer shell, and an inner shell is connected inside the installation groove; a buffer assembly, which is arranged between the foam box outer shell and the inner shell and is used for buffering impact force.

[0007] By adopting the above technical solution, by setting up a buffer component, during use, the buffer component absorbs and alleviates the impact force received by the outer shell of the foam box, reduces the damage caused by the impact force to the inner shell, and improves the protection effect.

[0008] Preferably, the buffer component includes: a buffer airbag connected to one side inside the installation groove; two air outlet holes are provided on one side of the buffer airbag, a connecting pipe is connected inside the air outlet hole, and one end of the connecting pipe is connected to an air inlet pipe; two installation boxes connected to the inner bottom surface of the installation groove, and the air inlet pipe passes through the installation box and extends to the inside; two extrusion grooves are provided inside the air inlet pipe, several springs are connected inside the extrusion groove, and one end of the spring is connected to a sealing plate.

[0009] By adopting the above technical solution, by setting up a buffer airbag, when the outer shell of the foam box is impacted, the buffer airbag receives the impact force, and the gas is compressed to absorb part of the impact energy. As the impact force increases, the gas pressure increases, which pushes the sealing plate to move. The movement of the sealing plate releases the seal of the connecting pipe, enabling the gas to be discharged into the installation box through the air inlet pipe, dispersing the impact force energy, thereby slowing down the impact force. Since the gas discharge process gradually reduces the pressure inside the buffer airbag, it realizes a slow deceleration, further reducing the damage to the items caused by the impact and improving the impact resistance of the foam box.

[0010] Preferably, an exhaust hole is provided on the top surface of the installation box, and an exhaust pipe is connected inside the exhaust hole.

[0011] By adopting the above technical solution, by setting up an exhaust pipe, when the gas pressure inside the installation box is too high, when the buffer airbag exhausts and the pressure values on both sides of the sealing plate are similar, it may cause the sealing plate to not move normally, affecting the use. By regularly discharging the gas inside the installation box through the exhaust pipe, the purpose of ensuring the normal movement of the sealing plate is achieved.

[0012] Preferably, an inflation hole is provided on the top surface of the buffer airbag, and a valve is connected inside the inflation hole.

[0013] By adopting the above technical solution, by setting up an inflation hole, during transportation, the valve is opened, and the staff injects air into the buffer airbag through the inflation hole to achieve the purpose of inflating the buffer airbag.

[0014] Preferably, buffer pads are respectively connected to the inner wall of the inner shell, and four cavities are formed between the buffer pads and the inner shell.

[0015] By adopting the above technical solution, by setting up buffer pads, the items placed inside the inner shell are secondarily buffered by the buffer pads, improving the protection effect.

[0016] Preferably, two hinges are connected to the top surface of the foam box outer shell, and one end of each hinge is connected to a protective plate.

[0017] By adopting the above technical solution, by setting the protective plate and closing the protective plate, the items inside the foam box are protected by the protective plate, improving the protection ability.

[0018] In summary, the present utility model mainly has the following beneficial effects:

[0019] By setting the buffer airbag, when the outer shell of the foam box is impacted, the buffer airbag is subjected to the impact force, and the gas is compressed to absorb part of the impact energy. As the impact force increases, the gas pressure increases, thereby pushing the sealing plate to move. The movement of the sealing plate releases the seal on the connecting pipe, allowing the gas to be discharged into the installation box through the intake pipe, dispersing the impact energy, thereby slowing down the impact force. Since the gas discharge process causes the pressure inside the buffer airbag to gradually decrease, slow deceleration is achieved, further reducing the damage to the items caused by the impact and improving the impact resistance of the foam box.

[0020] By setting the exhaust pipe, when the gas pressure inside the installation box is too high, during the exhaust of the buffer airbag, when the pressure values on both sides of the sealing plate are similar, it may cause the sealing plate to not move normally, affecting the use. By regularly discharging the gas inside the installation box through the exhaust pipe, the purpose of ensuring the normal movement of the sealing plate is achieved. By setting the inflation hole, during transportation, the valve is opened, and the staff injects air into the buffer airbag through the inflation hole to achieve the purpose of inflating the buffer airbag.

[0028] Reference Figures 1 - 5 , a foam box with good impact resistance, comprising a foam box outer shell 1. An installation groove 2 is formed in the top surface of the foam box outer shell 1. An inner shell 3 is connected inside the installation groove 2. A buffer assembly is arranged between the foam box outer shell 1 and the inner shell 3 for buffering impact force. By setting the buffer assembly, during use, the impact force received by the foam box outer shell 1 is absorbed and alleviated by the buffer assembly, reducing the damage caused by the impact force to the inner shell 3 and improving the protection effect. The buffer assembly includes a buffer airbag 4. The buffer airbag 4 is connected to one side inside the installation groove 2. Two air outlet holes 5 are formed in one side of the buffer airbag 4. A connecting pipe 6 is connected inside the air outlet hole 5. One end of the connecting pipe 6 is connected to an air inlet pipe 7. Two installation boxes 8 are connected to the inner bottom surface of the installation groove 2. The air inlet pipe 7 passes through the installation box 8 and extends to the inside. Two extrusion grooves 9 are formed inside the air inlet pipe 7. A plurality of springs 10 are connected inside the extrusion groove 9. One end of the spring 10 is connected to a sealing plate 11. By setting the buffer airbag 4, when the foam box outer shell 1 is impacted, the buffer airbag 4 receives the impact force, and the gas is compressed to absorb part of the impact energy. As the impact force increases, the gas pressure increases, thereby pushing the sealing plate 11 to move. The movement of the sealing plate 11 releases the seal of the connecting pipe 6, enabling the gas to be discharged into the installation box 8 through the air inlet pipe 7, dispersing the impact force energy, thereby slowing down the impact force. Since the gas discharge process gradually reduces the pressure inside the buffer airbag 4, slow deceleration is achieved, further reducing the damage to the items caused by the impact and improving the impact resistance of the foam box.

[0029] Refer to Figures 1 - 5, an exhaust hole 12 is provided on the top surface of the installation box 8, and an exhaust pipe 13 is connected to the inside of the exhaust hole 12. By providing the exhaust pipe 13, when the gas pressure inside the installation box 8 is too high, when the buffer airbag 4 exhausts air and the pressure values on both sides of the sealing plate 11 are similar, it may cause the sealing plate 11 to not move normally, affecting the use. By regularly discharging the gas inside the installation box 8 through the exhaust pipe 13, the purpose of ensuring the normal movement of the sealing plate 11 is achieved. An inflation hole 14 is provided on the top surface of the buffer airbag 4, and a valve 15 is connected to the inside of the inflation hole 14. By providing the inflation hole 14, during transportation, the valve 15 is opened, and the staff injects air into the buffer airbag 4 through the inflation hole 14 to achieve the purpose of inflating the buffer airbag 4. Buffer pads 16 are respectively connected to the inner wall of the inner shell 3, and four cavities are formed between the buffer pads 16 and the inner shell 3. By providing the buffer pads 16, the items placed inside the inner shell 3 are secondarily buffered through the buffer pads 16 to improve the protection effect. Two hinges are connected to the top surface of the foam box outer shell 1, and a protection plate 17 is connected to one end of the hinge. By providing the protection plate 17, when the protection plate 17 is closed, the items inside the foam box are protected by the protection plate 17 to improve the protection ability.

[0030] Working principle: Please refer to Figures 1 - 4 As shown, by providing the buffer airbag 4, when the foam box outer shell 1 is impacted, the buffer airbag 4 receives the impact force, and the gas is compressed to absorb part of the impact energy. As the impact force increases, the gas pressure increases, thereby pushing the sealing plate 11 to move. The movement of the sealing plate 11 releases the seal on the connecting pipe 6, allowing the gas to be discharged into the installation box 8 through the intake pipe 7, dispersing the impact energy, thereby slowing down the impact force. Since the gas discharge process causes the pressure inside the buffer airbag 4 to gradually decrease, slow deceleration is achieved, further reducing the damage to the items caused by the impact and improving the impact resistance of the foam box. By providing the exhaust pipe 13, when the gas pressure inside the installation box 8 is too high, when the buffer airbag 4 exhausts air and the pressure values on both sides of the sealing plate 11 are similar, it may cause the sealing plate 11 to not move normally, affecting the use. By regularly discharging the gas inside the installation box 8 through the exhaust pipe 13, the purpose of ensuring the normal movement of the sealing plate 11 is achieved. By providing the inflation hole 14, during transportation, the valve 15 is opened, and the staff injects air into the buffer airbag 4 through the inflation hole 14 to achieve the purpose of inflating the buffer airbag 4.
