Abstract
Description
Technical Field
[0001] This utility model belongs to the field of packaging box technology, specifically a heavy cargo anti-drop packaging box. Background Technology
[0002] Packaging boxes are large containers used for packaging, protecting, transporting, and storing various items. They are usually made of materials such as cardboard, wood, plastic, and metal. They play an important role in logistics, warehousing, and manufacturing, effectively protecting products from damage, improving transportation efficiency, and facilitating the handling and storage of goods.
[0003] A search revealed a shockproof packaging box (CN210593352U). It addresses the issue that during transportation, bumpy roads are inevitable, and the vibrations transmitted to the packaging box can affect the stability of the items inside. Especially when the box is accidentally dropped, the impact can be significant, easily damaging the contents. The solution utilizes springs and limiting plates. When items vibrate horizontally within the box, they contact the limiting plates, which, through a connecting rod, compress or stretch a second spring, thus buffering the vibrations and providing comprehensive protection. However, in practical use, it has shortcomings. Because the horizontal springs lack dampers, excessive impacts can cause them to aggravate the lateral swaying of the goods inside, reducing the horizontal buffering effect. Therefore, improvements are needed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1 to 8 As shown, this utility model provides a heavy-duty cargo anti-drop packaging box, including a packaging box body 1. A reinforcing strip 2 is fixedly sleeved on the outer surface of the packaging box body 1. A box cover 3 is movably sleeved on the top of the outer surface of the reinforcing strip 2. The bottom end of the box cover 3 is movably connected to the top end of the packaging box body 1. A rubber pad 4 is fixedly sleeved on the bottom end inside the packaging box body 1. Rubber rings 5 are fixedly installed around the top of the top of the rubber pad 4. The top of the outer surface of the rubber rings 5 is fixedly connected to the top of the inner surface of the packaging box body 1. Six airbags 6 are fixedly sleeved on the outer surface of the rubber rings 5. The six airbags 6 are all the same shape and size. The outer surface of the six airbags 6 is fixedly sleeved on the inner surface of the packaging box body 1. A connecting tube 7 is fixedly sleeved on the middle part of the front end of the outer surface of the six airbags 6. The front end of the connecting tube 7 passes through the packaging box body 1 and extends to the outside of the packaging box body 1 and is fixedly sleeved on the transition tube 8. The outer surface of the transition tube 8 and the... The inner surface of the front middle of the main body 1 of the packaging box is fixedly sleeved with an air inlet valve 9, and the middle of the front end of the transition tube 8 is fixedly sleeved with a pressure relief valve 10 located below the air inlet valve 9. When the air inlet valve 9 is opened to input air into the transition tube 8, since the transition tube 8 and the airbag 6 are connected by a connecting pipe 7, the air inside the transition tube 8 will enter the airbag 6 through the connecting pipe 7 as air enters. At this time, as air continues to enter, the airbag 6 will inflate. At the same time, the six airbags 6 are distributed in sequence on the inner surface of the main body 1 of the packaging box and are spaced apart, so the six airbags 6 will not affect each other. As the airbag 6 inflates, the rubber ring 5 will be pushed by the airbag 6 towards the heavy goods inside the main body 1 of the packaging box until it is in close contact with the heavy goods. In this way, the airbag 6 and the rubber ring 5 can provide horizontal cushioning for the heavy goods, thereby improving the anti-drop capability of the packaging box.
[0025] The first side plate 11 is fixedly sleeved on the left and right sides of the inner surface of the front and rear ends of the reinforcing strip 2, and the outer surface of the first side plate 11 is fixedly connected to the outer surface of the main body of the packaging box 1. The second side plate 12 is fixedly sleeved on the middle part of the inner surface of the left and right ends of the reinforcing strip 2, and the outer surface of the second side plate 12 is fixedly connected to the outer surface of the main body of the packaging box 1. Due to the presence of the first side plate 11 and the second side plate 12, the main body of the packaging box 1 will be strengthened and fixed, thereby improving the firmness of the main body of the packaging box 1 in conjunction with the reinforcing strip 2.
[0026] The packaging box body 1 has a protective cover 13 movably connected to the middle of the front end, which is located in front of the air intake valve 9 and the pressure relief valve 10. A handle 14 is fixedly installed at the middle of the bottom end of the protective cover 13. The presence of the protective cover 13 will protect the air intake valve 9 and the pressure relief valve 10, thereby preventing them from being damaged by collisions during transportation. The presence of the handle 14 makes it easy for operators to open the protective cover 13.
[0027] The protective cover 13 has a fixed frame 15 movably connected to the top of both ends. The rear end of the fixed frame 15 is fixedly connected to the front end of the packaging box body 1. A round shaft 16 is fixedly sleeved at the bottom end of the fixed frame 15. The outer surface of the round shaft 16 is movably sleeved with the inner surface of the top end of the protective cover 13. The fixed frame 15 provides support for the protective cover 13 and the round shaft 16. The round shaft 16 serves as the rotation axis of the protective cover 13, so that when the operator moves the handle 14, the handle 14 and the protective cover 13 can rotate around the round shaft 16.
[0028] The handle 14 has a baffle 17 movably sleeved on its outer surface. The rear end of the baffle 17 is movably connected to the front end of the packaging box body 1. The inner surfaces of the left and right ends of the baffle 17 are respectively movably sleeved with round rods 18. Since the baffle 17 and the handle 14 are movably sleeved, the presence of the baffle 17 will block and fix the handle 14. The presence of the round rods 18 can limit the movement of the baffle 17, thereby ensuring the stability of the movement of the baffle 17.
[0029] The top of the outer surface of the round rod 18 is fixedly fitted with a stop block 19, the bottom end of the stop block 19 is movably connected to the top end of the baffle 17, and a support block 20 is fixedly installed at the bottom end of the round rod 18. The rear end of the support block 20 is fixedly connected to the front end of the packaging box body 1. The presence of the stop block 19 will work with the round rod 18 to restrict the movement of the baffle 17, thereby preventing the baffle 17 and the round rod 18 from separating. The presence of the support block 20 will support and fix the round rod 18.
[0030] Among them, springs 21 located outside the round rod 18 are fixedly installed on the left and right sides of the top of the support block 20, and the other end of the spring 21 is fixedly connected to the bottom end of the baffle 17. When the spring 21 is in a compressed state, it will generate an upward force on the baffle 17 under the restoring action of the spring 21, so that the baffle 17 can maintain the engagement state with the handle 14 without being pushed by external force, thereby achieving the blocking and fixing of the handle 14.
[0031] Working principle and usage process of this utility model:
[0032] In use, after placing heavy goods inside the main body 1 of the packaging box, the operator moves the baffle 17, causing it to move along the outer surface of the round rod 18 and compress the spring 21, thus separating the baffle 17 from the handle 14. The operator can then move the handle 14, causing it to rotate around the round shaft 16 with the protective cover 13 as the axis, thereby opening the protective cover 13. After connecting the air inlet valve 9 and the inflation device, the operator opens the air inlet valve 9 to input air into the transition pipe 8. At this time, the air inside the transition pipe 8 will be input into the airbag 6 through the connecting pipe 7. As air continues to be input, the airbag 6 will push the rubber ring 5, making the rubber ring 5 tightly adhere to the heavy goods. Then the air inlet valve 9 can be closed and the inflation device removed. In this way, the cooperation between the airbag 6 and the rubber ring 5 can provide horizontal cushioning for the heavy goods, thereby improving the anti-drop effect of the packaging box.
[0033] After inflation is complete, the operator resets the protective cover 13 and handle 14, and then releases the baffle 17. At this time, under the restoring action of the spring 21, the baffle 17 will move along the outer surface of the round rod 18 until the baffle 17 and the stop block 19 come into contact. At this time, the baffle 17 will be in an engaged state with the handle 14, thereby blocking and fixing the handle 14. In this way, the protective cover 13 can protect the air intake valve 9 and the pressure relief valve 10, thereby preventing the air intake valve 9 and the pressure relief valve 10 from being damaged by collision during transportation, which would cause the air inside the airbag 6 to leak.
