[0025] 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.

[0026] like Figures 1 to 5 As shown, this utility model provides a supportless fast-charging membrane bag, including a membrane bag body 1, an air injection component 2 connected to the membrane bag body 1, and the membrane bag body 1 is composed of membrane bag units 101 connected longitudinally and transversely. The overall cushioning membrane bag is formed by connecting the membrane bag units 101 to each other, which can be assembled into a suitable size according to needs, so as to cushion and protect transported items.

[0027] The air injection assembly 2 includes an air inlet pipe 201, one end of which is equipped with a one-way air inlet valve 202. A first pipe connector 203 is installed on the air inlet pipe 201. The first pipe connector 203 is connected to an air injection pipe group 204. The air injection pipe group 204 is connected to the membrane bag unit 101, which can simultaneously inject air into all membrane bag units 101, thereby improving the inflation speed and facilitating the separation of the air injection assembly 2 for use with the membrane bag unit 101.

[0028] Specifically, the left and right sides of the main body 1 of the film bag are respectively connected to a first elastic band 3 and a second elastic band 4. The first elastic band 3 and the second elastic band 4 are respectively provided with a first hook and loop fastener 5 and a first hook and loop fastener 6, so as to make it convenient to wrap the main body 1 of the film bag with the items.

[0029] Furthermore, the left and right sides of the film bag unit 101 are respectively provided with corresponding second hook and loop fastener surfaces 7 and second hook and loop fastener surfaces 8, which facilitates the interconnection of the film bag unit 101 on the left and right sides.

[0030] Furthermore, the front and rear ends of the film bag unit 101 are respectively provided with corresponding movable buckles 9 and movable buckle grooves 10 for connecting the front and rear ends of the film bag unit 101.

[0031] It is worth noting that the air injection tube assembly 204 includes an air injection tube 2041 that runs through both ends of the membrane bag unit 101. The air injection tube 2041 inside the membrane bag unit 101 is equipped with a one-way air injection port 2042. Both ends of the air injection tube 2041 are provided with a second pipe joint 2043. Adjacent air injection tubes 2041 are connected through the second pipe joint 2043, so that the air injection tube assembly 204 can be connected to each other. The air injection tube assembly 204 and the membrane bag unit 101 form a separate unit for injecting air into the membrane bag unit 101.

[0032] It is worth noting that the second pipe joint 2043 at the end of the air injection pipe 2041 outside the membrane bag body 1 is connected to a cap 11, which is used to seal the second pipe joint 2043 that is not connected to other components. Both the first pipe joint 203 and the second pipe joint 2043 are designed as quick-connect interfaces.

[0033] Working principle and process: First, determine the size of the membrane bag body 1 according to the items to be protected. Then, select an appropriate number of membrane bag units 101. First, connect the front and rear ends of the membrane bag unit 101 by connecting the corresponding second pipe connectors 2043. Then, connect the front and rear membrane bag units 101 through the movable buckle 9 and the movable buckle groove 10. Subsequently, connect the left and right membrane bag units 101 by connecting the second hook and loop fastener 7 and the second hook and loop fastener 8 to form the membrane bag body 1. The first membrane bag unit 1 is located at the edge. The second pipe connector 2043 connects to the first pipe connector 203, thus connecting to the air inlet pipe 201. The second pipe connector 2043, located at the other edge of the membrane bag body 1, connects to the end cap 11, allowing the air source to connect to the one-way air inlet valve 202 of the air injection assembly 2. Gas is then injected into the air injection pipe assembly 204 through the one-way air inlet valve 202, the air inlet pipe 201, and the first pipe connector 203. After passing through the second pipe connector 2043 and the air injection pipe 2041, the gas is discharged into the membrane bag unit 101 through the one-way air injection port 2042, causing it to expand rapidly and thus serve as a buffer.
