[0018] like Figures 1 to 3As shown, the utility model relates to a high-barrier vacuum packaging bag, comprising a high-barrier bag body 1 formed by three-side sealing, a concave-convex buckle 2 is arranged on the inner side of the bag opening of the high-barrier bag body 1, a symmetrically arranged air bag 3 is fixedly connected to the outer side of the bag opening of the high-barrier bag body 1, an air cylinder 4 is fixedly connected to one side of the bag opening of the high-barrier bag body 1 to penetrate the bag opening, the interior of the air cylinder 4 is hollow, and the interior of the air cylinder 4 is connected to the interior of the air bag 3, a piston sheet 5 is slidably connected to the inner wall of the air cylinder 4, a cylinder hole 6 is opened at the end of the air cylinder 4 to penetrate the bag opening, and a sheet hole 7 is opened at the end of the piston sheet 5 to penetrate the bag opening, and a linkage rod 8 is fixedly connected to the other side of the bag opening of the high-barrier bag body 1 to penetrate the bag opening, and one end of the linkage rod 8 can be opened under the action of external force When the linkage rod 8 is inserted into the cylinder hole 6 and the sheet hole 7, its outer wall fits with the inner wall of the cylinder hole 6 and the sheet hole 7, and the linkage rod 8 drives it to slide on the inner wall of the air cylinder 4 through the friction force with the inner wall of the sheet hole 7. After the piston plate 5 moves with the linkage rod 8, its outer wall blocks the connection between the air cylinder 4 and the air bag 3; the bag opening and the concave-convex buckle 2 are opened by pulling the bag opening of the high-barrier bag body 1 to both sides. During this process, the gas in the air cylinder 4 is automatically discharged into the air bag 3, and the bag opening of the high-barrier bag body 1 is supported by the expansion of the air bag 3, so that the user does not need to continuously hold the bag opening open, and the process does not require the user to perform unnecessary special operations, thereby increasing the convenience of the high-barrier bag body 1 when loading and taking out food.
[0019] Furthermore, the opening of the barrel hole 6 near one end of the linkage rod 8 is designed to be arc-shaped; the arc-shaped portion can guide the linkage rod 8 when it is inserted into the barrel hole 6, increase the smoothness of the linkage rod 8 when it is inserted into the barrel hole 6, and reduce the probability that the linkage rod 8 cannot be accurately inserted into the barrel hole 6.
[0020] Furthermore, a paddle 9 is fixedly connected to one end of the linkage rod 8 away from the air cylinder 4 ; through the paddle 9 , a user can push the linkage rod 8 to move more easily by pressing the paddle 9 .
[0021] Furthermore, the outer edge of the paddle 9 away from the linkage rod 8 is gradually recessed toward the center thereof; the recessed portion allows the paddle 9 to fit the user's finger, thereby increasing the stability and convenience of the user when pushing the linkage rod 8 to move.
[0022] Furthermore, a carrying slot 10 is provided at the opening of the high-barrier bag 1 and passes through the carrying slot 10 . By providing the carrying slot 10 , the user can pick up the high-barrier bag 1 through the carrying slot 10 , which makes it easier to use and transport, thereby increasing the portability of the high-barrier bag 1 .
[0023] Furthermore, the linkage rod 8, the air cylinder 4 and the piston plate 5 are all made of rubber material; the rubber material can increase the friction between the linkage rod 8 and the air hole and the cylinder hole 6, thereby increasing the air tightness when they are in contact.
[0024] Working principle: When in use, the bag opening of the high-barrier bag body 1 is pulled to both sides to open the bag opening and the concave-convex buckle 2. During this process, the linkage rod 8 draws out the air cylinder 4 together with the bag opening, so that the linkage rod 8 drives the piston plate 5 to move to discharge the air in the air cylinder 4 into the air bag 3. After moving, the piston plate 5 blocks the connection between the air cylinder 4 and the air bag 3 to prevent gas leakage, thereby eliminating the need for the user to continuously open the bag opening, and the process does not require the user to perform extra special operations, thereby increasing the convenience of the high-barrier bag body 1 when loading and taking out food;
[0025] When the bag opening needs to be sealed, the user only needs to press the concave-convex buckle 2 to fit it and evacuate the internal air to make it vacuum, so that the concave-convex buckle 2 seals the bag opening of the high-barrier bag body 1, and insert the linkage rod 8 back into the air cylinder 4. Similarly, the linkage rod 8 drives the piston plate 5 to return to its original position to extract the gas in the airbag 3, so that the airbag 3 no longer supports the closed bag opening of the high-barrier bag body 1, thereby increasing the stability of the bag opening of the high-barrier bag body 1 when it is closed by the concave-convex buckle 2, and preventing the airbag 3 from affecting the sealing of the bag opening of the high-barrier bag body 1.
[0026] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
