Description

Technical Field

[0001] This utility model relates to the field of inflatable bag technology, specifically an inflatable bag with strong pressure resistance. Background Technology

[0002] Inflatable bags, also known as air-filled packaging bags, provide comprehensive cushioning protection for packaged items, effectively reducing the probability of damage during transportation. Inflatable bags are characterized by low cost, space saving, recyclability, and non-polluting properties. They also offer long-term, leak-proof shock protection and are now widely used in the transportation and handling of electronic products, ceramic products, and precision instruments. When packaging large items such as watches, auto parts, and pianos, or fragile items such as glass, vases, and porcelain, high-strength inflatable bags must be used for cushioning protection to prevent damage.

[0003] Some inflatable bags have the following drawbacks: they lack structures to enhance the strength of the inflatable bag on its outer surface; when the air pressure inside the inflatable bag is too high, it is prone to rupture; and when the air pressure inside the inflatable bag is too low, it weakens the cushioning and protective effect of the inflatable bag. Utility Model Content

[0004] The purpose of this invention is to provide an inflatable bag with strong pressure resistance to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An inflatable bag with high pressure resistance includes a side airbag, an upper airbag membrane, a lower airbag membrane, and a diaphragm.

[0007] The upper airbag membrane is fixedly connected to the top of the side airbag, and the lower airbag membrane is fixedly connected to the bottom of the variable airbag. The diaphragm is disposed between the upper airbag membrane and the lower airbag membrane. The edge of the diaphragm is fixedly connected to the connection between the upper airbag membrane and the side airbag. An upper air layer is disposed between the upper airbag membrane and the diaphragm, and a lower air layer is disposed between the lower airbag membrane and the diaphragm.

[0008] A sealing and fixing plate is installed inside the lower air bag membrane. The sealing and fixing plate has ventilation holes. One end of the mounting cylinder is fixedly connected to the sealing and fixing plate. The other end of the mounting cylinder is fixedly connected to the diaphragm. The diaphragm has a groove that communicates with the upper air layer. An elastic rubber membrane is fixedly connected inside the mounting cylinder.

[0009] As a further embodiment of this utility model: a second traction belt is fixedly connected between the upper air bag membrane and the diaphragm.

[0010] As a further embodiment of this utility model: a first traction belt is fixedly connected between the lower air bag membrane and the diaphragm.

[0011] As a further embodiment of this utility model: a first inflation valve is installed inside the upper air bag membrane, and the first inflation valve is connected to the upper air layer.

[0012] As a further embodiment of this utility model: a lifting ring is fixedly connected to the suture line of the side airbag.

[0013] As a further improvement of this utility model: a second inflation valve is installed inside the side airbag, and the second inflation valve is connected to the lower air layer.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model sets up an upper air layer and a lower air layer in the inflatable bag by setting a diaphragm. The air pressure in the upper air layer on the side closer to the workpiece is higher, while the air pressure in the lower air layer on the side farther away from the workpiece is lower. This improves the strength of the inflatable bag while ensuring the cushioning and protection effect of the inflatable bag. Furthermore, the setting of the elastic rubber membrane improves the pressure bearing capacity of the equipment. Attached Figure Description

Detailed Implementation

[0019] 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.

[0020] See Figures 1-3In this embodiment of the present invention, an inflatable bag with strong pressure resistance includes a side air bladder, an upper air bladder membrane 4, a lower air bladder membrane 5, and a diaphragm 6. The upper air bladder membrane 4 is fixedly connected to the top of the side air bladder, the lower air bladder membrane 5 is fixedly connected to the bottom of the side air bladder, the diaphragm 6 is disposed between the upper air bladder membrane 4 and the lower air bladder membrane 5, and the edge of the diaphragm is fixedly connected to the connection between the upper air bladder membrane 4 and the side air bladder. An upper air layer is disposed between the upper air bladder membrane 4 and the diaphragm 6, and a lower air layer is disposed between the lower air bladder membrane 5 and the diaphragm 6.

[0021] A sealing fixing plate 10 is sealed and installed inside the lower air bag membrane 5. A ventilation hole 11 is provided inside the sealing fixing plate 10. One end of the mounting cylinder 12 is fixedly connected to the sealing fixing plate 10. The other end of the mounting cylinder 12 is fixedly connected to the diaphragm 6. A groove is provided inside the diaphragm 6, and the groove is connected to the upper air layer. An elastic rubber membrane 13 is fixedly connected inside the mounting cylinder 12.

[0022] This invention first establishes an upper and lower air layer within an airbag by arranging a side airbag, an upper airbag membrane 4, a lower airbag membrane 5, and a diaphragm 6. Gas is then injected into both the upper and lower air layers. At this point, the upper air layer has a higher pressure, while the lower air layer has a lower pressure. When pressure is applied to the upper airbag membrane 4, it first acts on the lower air layer through the gas in the upper air layer, thus compressing the gas in the lower air layer. When the gas in the upper air layer is compressed, the pressure difference across the elastic rubber membrane 13 changes, increasing the pressure on the elastic rubber membrane 13 and causing it to deform. This reduces the impact of increased pressure in the upper air layer on the upper airbag membrane 4 and the diaphragm 6. Furthermore, when the lower air layer is compressed, its lower pressure results in a stronger compressibility, thereby enhancing the overall pressure-bearing capacity of the airbag.

[0023] In one instance of this embodiment, please refer to Figures 1-3 A second traction belt 14 is fixedly connected between the upper air bag membrane 4 and the diaphragm 6, and a first traction belt 7 is fixedly connected between the lower air bag membrane 5 and the diaphragm 6.

[0024] This invention uses the first traction belt 7 and the second traction belt 14 to traction and position the upper air bag film 4, the diaphragm 6, and the lower air bag film 5, thereby preventing the upper air bag film 4, the diaphragm 6, and the lower air bag film 5 from deforming under the push of high-pressure gas.

[0025] In one instance of this embodiment, please refer to Figures 1-3 The upper air bag membrane 4 is equipped with a first inflation valve 8, which is connected to the upper air layer. The side air bag 1 is equipped with a second inflation valve 9, which is connected to the lower air layer.

[0026] This invention uses a first inflation valve 8 to inflate the upper air layer and a second inflation valve 9 to inflate the lower air layer, thus controlling the air pressure between the upper and lower air layers.

[0027] In one instance of this embodiment, please refer to Figures 1-3 A lifting ring 3 is fixedly connected to the suture line 2 of the side airbag 1. The lifting ring 3 facilitates the carrying of the device.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
