[0015] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Please refer to Figures 1 to 2 The first embodiment of the present invention: An environmentally friendly and highly plastic woven bag includes an outer bag body 1, an inner bag body 2, an air bladder 5, a one-way valve pipeline 6, an outer protective plate 3, and an adjustment mechanism 4. The inner bag 2 is fitted inside the outer bag 1, and the gap between the inner bag 2 and the outer bag 1 is a closed cavity. The bag opening of the inner bag 2 is provided with a sealing structure 21. The airbag 5 is U-shaped and located at the bottom of the closed cavity. The outer wall of the airbag 5 is bonded to the outer bag body 1, and the inner wall of the airbag 5 is bonded to the inner bag body 2. One-way valve line 6 connects inner bag 2 and airbag 5. One-way valve line 6 can only allow air to enter from inner bag 2 to airbag 5, and it will self-seal in the opposite direction. Among them, the outer protective plate 3 is provided in two sets, which are distributed on both sides of the outer bag body 1, and the adjustment mechanism 4 is used to adjust the distance between the two sets of outer protective plates 3. When in use, the airbag 5 is in a deflated, uninflated state. The inner bag 2, outer bag 1, and airbag 5 are tightly attached together. Open the opening of the inner bag 2 and place the item inside. The inner bag 2 is then sealed by the sealing structure 21. Adjusting the two sets of outer protective plates 3 causes them to move in opposite directions, opening the outer bag 1 to the sides. However, due to the weight of the item, the inner bag 2 will not fully open to the sides with the outer bag 1. At this time, the gas inside the inner bag 2 will be introduced into the airbag 5 through the one-way valve pipe 6, achieving rapid inflation of the airbag 5. After inflation, the airbag 5 can protect the item inside the inner bag 2 and simultaneously draw out the gas inside the inner bag 2, compressing the inner bag 2 and positioning and binding the item inside, preventing the item from moving inside the inner bag 2.

[0017] refer to Figures 3-4 In this embodiment, the adjustment mechanism 4 includes a connecting plate 41, a lifting block 43, and a connecting rod 44; The connecting plate 41 is fixedly installed on one side wall of the outer bag body 1 between the two sets of outer protective plates 3, and a vertical groove 42 is provided on the connecting plate 41. The lifting block 43 can slide up and down within the vertical groove 42, and a connecting shaft is provided on the lifting block 43; There are two sets of connecting rods 44. One end of the connecting rod 44 is hinged to the connecting shaft, and the other end of the connecting rod 44 is hinged to each outer protective plate 3. By moving the sliding lifting block 43 within the vertical groove 42, when the two sets of connecting rods 44 are connected in a straight line, the distance between the two sets of outer protective plates 3 is at its maximum, and the two side walls of the outer bag body 1 can quickly open to both sides.

[0018] It should be noted that the one-way valve pipeline 6 is equipped with an openable and closable end cap at one end inside the inner bag body 2. When the end cap is opened, the gas inside the inner bag body 2 will be input into the airbag 5 through the one-way valve pipeline 6.

[0019] refer to Figure 5 The second embodiment of the present invention: An environmentally friendly and highly malleable woven bag includes a lifting block 43 with a fixing component 45. The fixing component 45 includes a limiting plate 451, a limiting rod 456, a spring 452, a support rod 454, and a handle 453. A limiting cavity is formed within the lifting block 43, and the limiting plate 451 is installed within the limiting cavity. The limiting rod 456 connects to the limiting plate 451 and extends towards a vertical groove 42. Multiple limiting slots 455 corresponding to the limiting rod 456 are formed vertically within the vertical groove 42. The other side of the limiting plate 451 is connected to the support rod 454. The spring 452 is sleeved on the support rod 454 and extends to the outside of the lifting block 43. Under the action of the spring 452, the limiting rod 456 enters the corresponding limiting groove 455. When in use, the handle 453 is manually pulled outward to disengage the limiting rod 456 from the limiting groove 455. At this time, the lifting block 43 can move within the vertical groove 42. When the lifting block 43 moves to the ideal position, the handle 453 is released. Under the action of the spring 452, the limiting rod 456 enters the limiting groove 455, thereby fixing the position of the lifting block 43.

[0020] In this embodiment, an exhaust port 51 is provided at the bottom of the airbag 5. The exhaust port 51 extends to the outside of the outer bag body 1 and is used to exhaust air from the airbag 5.

[0021] In this embodiment, the sealing structure 21 includes two airtight sealing strips that can be repeatedly opened and closed. The two airtight sealing strips are respectively set on the inner walls on both sides of the bag opening of the inner bag body 2.

[0022] In this embodiment, the inner bag body 2 is made of interwoven glass fibers of polypropylene or polyethylene, and a sealing inner film is provided inside the inner bag body 2. The sealing inner film is made of PET material. The working principle of this invention is as follows: The airbag 5 is in a deflated, uninflated state. The inner bag 2, outer bag 1, and airbag 5 are tightly attached together. The opening of the inner bag 2 is opened, and the item is placed inside the inner bag 2. The inner bag 2 is sealed by the sealing structure 21. Then, by adjusting the two sets of outer protective plates 3, the two sets of outer protective plates move in opposite directions, causing the outer bag 1 to open to both sides. Under the weight of the item, the inner bag 2 will not completely open to both sides with the outer bag 1. At this time, the gas in the inner bag 2 will be input into the airbag 5 through the one-way valve pipeline 6, realizing the rapid inflation of the airbag 5. After the airbag 5 is inflated, it can protect the item inside the inner bag 2 and at the same time suck out the gas inside the inner bag 2, so that the inner bag 2 is in a compressed state, which can play a role in positioning and binding the item inside the inner bag 2, preventing the item from moving inside the inner bag 2.

[0023] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention's specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.

[0024] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
