[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] In Figures 1-4 In the shown embodiment, the present invention provides a technical solution: an air column bag for spherical products, including a lower cavity 4 and an upper cavity 1 that can rotate around the lower cavity 4. Both the upper cavity 1 and the lower cavity 4 are semi-spherical inflatable structures and can be combined into a spherical shape to package spherical products. A connecting cavity column 5 is adhesively provided between one side of the upper cavity 1 and the lower cavity 4. The connecting cavity provides the connection function for the upper cavity 1 and the lower cavity 4 to realize the opening and closing function.

[0026] In practical applications, compared with the existing air column bags, a locking part 2 is adhesively provided on the side of the upper cavity 1 opposite to the connecting cavity column 5.

[0027] Further, a connecting column 8 is provided at the position of the lower cavity 4 corresponding to the locking part 2. The top of the connecting column 8 is provided with a lock catch 3. The lock catch 3 is set as an elastic inflatable ball and can realize the locking and opening and closing functions of the upper cavity 1 and the lower cavity 4 with the locking part 2, ensuring more stable packaging of spherical products.

[0028] In Figures 2-4 In the shown embodiment, an inflatable column 6 is adhesively provided at the center of the top of the upper cavity 1. The inflatable column 6 provides the inflation function for the air column bag. The top of the inflatable column 6 is provided with an automatic inflation device 7 connected. The automatic inflation device 7 can more conveniently and quickly inflate the overall air column bag and improve the inflation efficiency.

[0029] In some embodiments, the automatic inflation device 7 includes a ventilation column 9. The ventilation column 9 is directly connected to the inflatable column 6. The top of the ventilation column 9 is provided with an air sealing column 10. The inner center of the air sealing column 10 is provided with a lock hole 17. The air sealing column 10 provides the air sealing function when not inflated. The top of the air sealing column 10 is provided with a lower locking column 11 connected. Above the lower locking column 11 is provided with an upper locking column 13. The upper locking column 13 and the lower locking column 11 provide the air locking function after inflation.

[0030] Furthermore, a locking ring 12 is adhesively provided between the upper locking column 13 and the lower locking column 11. The upper locking column 13 is connected with a capping column 14, and the capping column 14 provides a sealing function.

[0031] Furthermore, a pull rope 16 passes through and is slidably connected to the top of the capping column 14. A pull ball 15 is provided at the top of the pull rope 16, and the pull ball 15 provides a fulcrum for pulling.

[0032] Furthermore, a locking ball 18 is connected to the bottom of the pull rope 16. The locking ball 18 is arranged directly below the locking hole 17. A sealing air disk 19 is connected to the bottom of the locking ball 18. A sealing air ring 20 is provided on the outer ring side of the sealing air disk 19, and the sealing air function is realized through the action of the sealing air ring 20.

[0033] The specific working principle of the present utility model will be elaborated in detail below: When not inflated, the upper cavity 1 and the lower cavity 4 of the air column bag are in a deflated state, which is convenient for storing the air column bag. At this time, the locking ball 18 is below the locking hole 17. By utilizing the interaction between the locking ball 18 and the locking hole 17, the air sealing function of the air column bag is realized. When inflation is required, the pull ball 15 is pulled, and the pull rope 16 drives the locking ball 18 to squeeze the locking hole 17, and the locking hole 17 becomes larger. Air instantly enters the automatic inflation device 7. After passing through the inflation column 6, the upper cavity 1 and the lower cavity 4 are inflated and expanded. After the expansion is completed, the sealing air disk 19 and the sealing air ring 20 enter the locking ring 12 and are fastened, thereby achieving the air sealing effect on the overall air column bag. When packaging spherical products, the upper cavity 1 is lifted, and the upper cavity 1 rotates around the connecting cavity column 5. The upper cavity 1 is opened, and the product is placed into the upper cavity 1 and the lower cavity 4. The upper cavity 1 is fastened, and by utilizing the interaction between the lock 3 and the locking part 2, the spherical product is further fixed to ensure the stability of the packaging during transportation.

[0034] In summary, an air column bag for spherical products of the present utility model can achieve rapid inflation and provide a stable transportation packaging environment for spherical products with low stability.

[0035] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
