Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically a packaging box with leak-proof function. Background Technology

[0002] In the modern process of commodity circulation and storage, packaging boxes play a vital role. They not only provide basic containment and protection for goods, preventing damage from collisions and compression during transportation, handling, and storage, but also meet the specific storage environment requirements of different items.

[0003] Currently, some existing packaging boxes have poor sealing performance and are only fixed with a simple buckle structure. When subjected to bumps or pressure, the cover may open slightly, causing small items stored inside to leak. If toxic or harmful substances leak, it will also pose a safety hazard, reducing the practicality of the packaging box. Meanwhile, some existing packaging boxes are subject to external impacts and vibrations during transportation, causing the contents to shake and collide inside the box. This can easily lead to breakage of fragile items, and for liquids or powders, violent shaking may cause pressure changes inside the container, increasing the risk of leakage. Utility Model Content

[0004] The purpose of this invention is to provide a packaging box with leak-proof function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a packaging box with leak-proof function, comprising a packaging box body and an inner surface sealing sleeve fixedly connected to its top, and further comprising: A cover plate is provided on the top of the sealing sleeve. Connecting plates are fixedly connected to both sides of the top of the cover plate. Fixed boxes are fixedly connected to the top of both sides of the packaging box body. A limiting mechanism that can fix and seal the cover plate is installed on one side of the inner cavity of the fixed box. A buffer plate is fixedly connected to the bottom of the inner cavity of the packaging box body. An airbag that can limit and buffer is fixedly connected to the inner cavity of the packaging box body. A connecting tube is connected to one side of the airbag.

[0014] 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.

[0015] Please see Figure 1-4As shown, a leak-proof packaging box includes a packaging box body 1. A sealing sleeve 2 is fixedly connected to the inner surface of the top of the packaging box body 1. A cover plate 3 is provided on the top of the sealing sleeve 2. By pressing the cover plate 3 onto the packaging box body 1, the sealing sleeve 2 can be squeezed and sealed, effectively sealing the packaging box body 1. Connecting plates 4 are fixedly connected to both sides of the top of the cover plate 3. Fixing boxes 5 are fixedly connected to the top of both sides of the packaging box body 1. A limiting mechanism 6 is installed on one side of the inner cavity of the fixing box 5 to fix and seal the cover plate 3. The limiting mechanism 6 can lock and fix the cover plate 3 and the connecting plates 4 to a tight seal, preventing them from opening when affected by external factors, thereby improving the leak-proof effect, preventing leakage from causing safety hazards, and improving the practicality of the packaging box body 1. A buffer plate 11 is fixedly connected to the bottom of the inner cavity of the packaging box body 1. The buffer plate 11 is made of rubber material. By choosing rubber material for the buffer plate 11, it is determined that rubber has good cushioning properties. The airbag 10 provides cushioning protection for the bottom of the item and works in conjunction with the airbag 11 to achieve a good cushioning effect. The inner cavity of the packaging box body 1 is fixedly connected to the airbag 10, which can limit and cushion the item. One side of the airbag 10 is connected to the connecting pipe 7. With the airbag 10 and the buffer plate 11, the airbag 10 can be inflated through the connecting pipe 7 using an air pump. The inflated airbag 10 can limit the item and prevent it from shaking. In addition, the buffer plate 11 can cushion and protect the item and prevent it from breaking and leaking due to collision. The outer surface of the connecting pipe 7 is provided with a cap 9. The cap 9 can cover the air inlet of the connecting pipe 7 to prevent foreign objects from entering and causing blockage, thus preventing the airbag 10 from being unable to be inflated. The top of the connecting pipe 7 is provided with a valve 8. The top of the valve 8 is provided with a knob. The valve 8 can be turned after the airbag 10 is inflated to prevent gas leakage, thus preventing the limiting and cushioning effect from being affected.

[0016] The limiting mechanism 6 includes springs 601 fixedly connected to both ends of one side of the inner cavity of the fixed box 5. An inclined plate 602 is fixedly connected to the other side of the springs 601. A sliding rod 603 is fixedly connected to one side of the inclined plate 602, and a pull plate 604 is fixedly connected to the other side of the sliding rod 603. The outer surface of the sliding rod 603 is slidably connected to the inner surface of one side of the fixed box 5. The inclined plate 602 is slidably connected to one side of the connecting plate 4. Guide blocks 12 are fixedly connected to the top and bottom of the inclined plate 602. Guide rails 13 are fixedly connected to the top and bottom of the inner cavity of the fixed box 5. The outer surface of the guide block 12 slides against the inner surface of the guide rail 13. The connection is achieved through the setting of the limiting mechanism 6. The connecting plate 4 slides down the inclined plane 602 to apply pressure to the spring 601, which can drive the inclined plane 602, the slide rod 603 and the pull plate 604 to move to one side. When the bottom of the connecting plate 4 reaches the lowest point, the pressure on the spring 601 is released. The elasticity of the spring 601 drives the inclined plate 602 to move to the other side, which can lock and fix the connecting plate 4 and the cover plate 3, improving the anti-leakage effect. The guide block 12 and the guide rail 13 can support the inclined plate 602, making it more stable when moving, and at the same time preventing the spring 601 from shifting in angle.

[0017] Working principle: First, place the items into the packaging box body 1, then remove the cap 9 and turn the valve 8 to release the seal. Use an air pump to inflate the airbag 10 through the connecting pipe 7. The inflated airbag 10 can limit the items, and with the cooperation of the buffer plate 11, it can cushion and protect the items. Then, align the connecting plate 4 with the opening of the fixed box 5, and press the cover plate 3 onto the packaging box body 1 to compress and seal the sealing sleeve 2. At the same time, the connecting plate 4 slides down the inclined plate 602 to apply pressure to the spring 601, which can drive the inclined plate 602, the sliding rod 603 and the pull plate 604 to one side. When the bottom of the connecting plate 4 reaches the bottom, release the pressure on the spring 601. Use the elasticity of the spring 601 to drive the inclined plate 602 to the other side, which can lock and seal the connecting plate 4 and the cover plate 3. When it is necessary to remove the items, pull the sliding rod 603 and the inclined plate 602 by pulling the pull plate 604 to release the lock on the connecting plate 4.
