DETAILED DESCRIPTION

[0017] The technical scheme of the patent will be further described in detail in combination with specific implementation manners.

[0018] Please refer to Figures 1-3An inflatable cushioning bag, comprising a bag body 1, fixed seats 12 are arranged at both ends in the bag body 1, a fixed frame 13 is arranged between the two fixed seats 12, and further comprising:

[0019] An inflatable cavity 3 is arranged in the bag body 1, a gas pipe 4 is arranged on the bag body 1, the gas pipe 4 is fixedly connected with a gas guide pipe 5, the gas guide pipe 5 is provided with an air inlet pipe 8 in communication with the inflatable cavity 3, both sides of the bag body 1 are provided with external air bags 6 connected with the gas guide pipe 5, the external air bags 6 are provided with air bag cavities 7 in communication with the gas guide pipe 5, and a protective layer 2 is arranged on the outside of the bag body 1.

[0020] A cushioning assembly is arranged on the fixed frame 13 and used for cushioning and protecting both sides of the bag body 1.

[0021] In use, the external inflating device is connected with the gas pipe 4 on the bag body 1, and inflation is started, air enters the gas guide pipe 5 from the air inlet pipe, and then flows into the air bag cavities 7 of the external air bags 6 from both sides of the gas guide pipe 5, so that the external air bags 6 are inflated first, when the air in the air bag cavities 7 of the external air bags 6 is filled, the air enters the inflatable cavity 3 from the air inlet pipe 8, and inflation of the inflatable cavity 3 is started, after the inflatable cavity 3 is inflated, the external inflating device is separated from the gas pipe 4, and then when the goods are transported by the vehicle, the bag body 1 is arranged between the goods and the inner wall of the vehicle compartment, so that collision between the goods and the inner wall of the vehicle compartment caused by shaking during the transportation of the vehicle is avoided, and deformation and damage of the goods are avoided, in addition, the protective layer 2 outside the bag body 1 provides the first layer of protection, the bag body 1 can continue to provide cushioning protection for the goods, and when the protective layer 2 is punctured, the sharp object will pierce into the external air bags 6, at this time, the external air bags 6 are damaged and leak, and then the inflatable cavity 3 in the bag body 1 is still in the inflated state and can still provide cushioning protection, thereby providing the second layer of protection, in addition, when the sharp object pierces the external air bags 6 and enters the inflatable cavity 3, the cushioning assembly can still provide cushioning protection for the goods in the vehicle compartment, and the third layer of protection is provided, and the three layers of protection can effectively protect the goods by the cushioning bag.

[0022] In one case of the embodiment, the gas pipe 4 is provided with a first one-way valve 9, both sides of the gas guide pipe 5 are provided with second one-way valves 10, and the air inlet pipe 8 is provided with a third one-way valve 11, the first one-way valve 9, the second one-way valves 10 and the third one-way valve 11 are arranged to enable the gas pipe 4 to only deliver air to the gas guide pipe 5, the gas guide pipe 5 to only deliver air to the external air bags 6 and the air inlet pipe 8, and the air inlet pipe 8 to only inflate the inflatable cavity 3.

[0023] When the inflating tube 4 is connected with the external inflating device and the inflating is started, air will enter the air guide tube 5 through the first one-way valve 9, at this time, the air pressure will first open the second one-way valve 10, so that the air enters the air bag cavity 7 of the external air bag 6 from the second one-way valve 10, then when the air bag cavity 7 of the external air bag 6 is filled with air, the third one-way valve 11 will be opened under the pressure of the air, so as to start inflating the inflating cavity 3, when the inflating cavity 3 is filled with air, the whole inflating process is completed.

[0024] In one case of the embodiment, the buffer assembly comprises a U-shaped frame 14 which is in sliding connection with the fixing frame 13, one end of the U-shaped frame 14 is provided with a stop block 15, and the other end is provided with a support plate 17 which faces the external air bag 6, and a spring 16 is arranged between the support plate 17 and the fixing frame 13 and is sleeved on the fixing frame 13.

[0025] When the protective layer 2, the external air bag 6 and the inflating cavity 3 are all punctured and broken by the external sharp object, the support plate 17 on the U-shaped frame 14 can provide the buffering effect in cooperation with the spring 16, and a damping shock absorber is further arranged between the support plate 17 and the fixing frame 13, so as to damp and absorb the spring 16, so that the buffering effect is better.

[0026] In one case of the embodiment, the distance between the support plate 17 and the fixing frame 13 is greater than the distance between the baffle and the fixing frame 13.

[0027] The lengths of the two ends of the U-shaped frame 14 are different, so that the movement range of the U-shaped frame 14 can be limited in cooperation with the stop block 15, so as to avoid excessive movement of the U-shaped frame 14 and cause the spring 16 to be excessively squeezed and damaged.

[0028] In use, this invention connects an external air inflator to the air inflator tube 4 on the bag body 1 and begins inflating. Air enters the air guide tube 5 through the inlet tube and then flows into the air chamber 7 of the external airbag 6 from both sides of the air guide tube 5, causing the external airbag 6 to inflate first. Once the air chamber 7 of the external airbag 6 is full, air enters the inflation chamber 3 through the air inlet tube 8, inflating the inflation chamber 3. After the inflation chamber 3 is fully inflated, the external air inflator is separated from the air inflator tube 4. When transporting goods by vehicle, the bag body 1 is placed between the goods and the inner wall of the vehicle compartment to prevent the goods from shaking and causing leakage between the goods and the inner wall of the vehicle compartment during transportation. In the event of a collision that causes deformation or damage to the goods, the protective layer 2 on the outside of the bag 1 provides a first layer of protection, preventing the bag 1 from being punctured by sharp objects on the goods. This allows the bag 1 to continue to provide cushioning protection for the goods. When the protective layer 2 is punctured, the sharp object will pierce the external airbag 6. At this time, the external airbag 6 will rupture and leak air, but the inflation chamber 3 inside the bag 1 will still be inflated, providing cushioning protection and thus providing a second layer of protection. In addition, even if a sharp object punctures the external airbag 6 and pierces the inflation chamber 3, the cushioning components can still cushion the goods inside the compartment, providing a third layer of protection. Through these three layers of protection, the cushioning bag can effectively protect the goods.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
