Description

Technical Field

[0001] This utility model relates to the field of air column bag technology, and more specifically, to a multi-stage cushioning air column bag. Background Technology

[0002] Air column bags are a new type of packaging material, often used to wrap around the outside of goods during transportation to prevent them from being bumped or knocked by the outside environment, thus protecting the goods.

[0003] Currently, air column bags are typically inflated by using an air pump to force air into the opening of the bag. This air is then distributed to the various chambers within the bag, causing it to expand outwards. Simultaneously, a reversible valve within the chamber prevents leakage, thus inflating the bag. When the air column bag encloses an item, the air inside isolates the item from the outside environment and provides cushioning, enhancing its protection.

[0004] However, when using air column bags to transport goods, the air column bags are inevitably affected by road bumps and collide with other objects. When the objects are sharp, they may puncture the air column bags, causing the cavity inside the air column bags to leak and affecting the cushioning effect of the air column bags on the goods.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-level cushioning air column bag, which solves the problem that when the external object is sharp, the external object will puncture the air column bag, causing leakage of the cavity inside the air column bag and affecting the cushioning effect of the air column bag on the object.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a multi-stage buffer air column bag, including an air column bag body with an air passage and a reversing valve, wherein the inner wall of the air column bag body is provided with a plurality of insulating sheets to block the wounds of the air column bag body punctured by external objects, and one side of the insulating sheet is fixedly connected to the inner wall of the air column bag body.

[0008] The present invention is further configured such that when the side wall of the insulating sheet and the inner wall of the air column bag body are in contact with each other, the side of the insulating sheet away from its connection with the air column bag body is in contact with another insulating sheet.

[0009] The present invention is further configured such that the insulating sheet is inclined.

[0010] The present invention is further configured such that: a connecting piece is fixedly connected inside the air column bag body, and the reversing valve is located between the connecting piece and the air column bag body.

[0011] The present invention is further configured such that a support piece is fixedly connected between the two connecting pieces.

[0012] The present invention is further configured such that the cross-section of the support plate is wavy.

[0013] In summary, this utility model has the following beneficial effects:

[0014] When air leaks outward from inside the air column bag, the insulating sheet is affected by the air pressure difference between the inside of the air column bag and the outside air, which can block the opening on the air column bag. Therefore, the air inside the air column bag cannot leak outward through the opening, thus avoiding affecting the cushioning effect of the air column bag. Attached Figure Description

[0023] A multi-stage cushioning air column bag, such as Figures 1-4 As shown, the air column bag body 3 includes an airway 1 and a reversing valve 2. The inner wall of the air column bag body 3 is provided with several insulating sheets 4 to block any wounds caused by external objects. The insulating sheets 4 are made of thin film and have a certain degree of flexibility. When an object comes into contact with the insulating sheet 4, it can be driven to deform, preventing the insulating sheet 4 from being punctured by the object. One side of the insulating sheet 4 is fixedly connected to the inner wall of the air column bag body 3. When the side wall of the insulating sheet 4 and the inner wall of the air column bag body 3 are in contact, the side of the insulating sheet 4 away from its connection with the air column bag body 3 comes into contact with another insulating sheet 4, which can increase the coverage of the insulating sheet 4 and improve the isolation effect on the wounds on the air column bag body 3. The insulating sheet 4 is set at an angle, which can facilitate the deformation of the insulating sheet 4 towards the inner wall of the air column bag body 3.

[0024] When the air column bag body 3 is punctured by a sharp object, an opening appears on the surface of the air column bag body 3. At this time, the air inside the air column bag body 3 leaks out through the opening. When the air inside the air column bag body 3 leaks out, the insulating plate 4 is affected by the air pressure difference between the air inside the air column bag body 3 and the outside air, which applies a pushing force to the insulating plate 4, causing the insulating plate 4 to deform towards the inner wall of the air column bag body 3 and stick to the inner wall of the air column bag body 3. At this time, the opening on the air column bag body 3 is blocked by the insulating plate 4, so the air inside the air column bag body 3 cannot leak out through the opening. Compared with the current air column bag, this structure can block the opening on the air column bag body 3 in time, prevent the continuous leakage of air inside the air column bag body 3, and avoid the situation where the air column bag body 3 loses its buffering capacity after the air inside the air column bag body 3 has leaked out. It preserves the buffering capacity of the air column bag body 3 after being punctured as much as possible.

[0025] like Figures 1-4As shown, a connecting piece 5 is fixedly connected inside the air column bag body 3. The connecting piece 5 is made of a thin film. The reversing valve 2 is located between the connecting piece 5 and the air column bag body 3. It can divide the cavity inside the air column bag body 3 to prevent the air in the air column bag body 3 from completely leaking out, thereby further improving the protective effect of the air column bag on the items. A support piece 6 is fixedly connected between the two connecting pieces 5, which can keep the two connecting pieces 5 at all times and reduce the risk of the air column bag body 3 being completely penetrated by sharp objects. The cross-section of the support piece 6 is wavy, which can further improve the support effect of the support piece 6 on the two connecting pieces 5.

[0026] The manufacturing process of this utility model is as follows:

[0027] When making the air column bag, the insulating sheet 4 is glued to the side wall of the air column bag body 3. Then, the two connecting pieces 5 and the supporting piece 6 are fixed together. Then, the reversing valve 2 is fixed between the connecting piece 5 and the side wall of the air column bag body 3. Finally, the edge sealing machine is used to seal the air column bag body 3 and the connecting piece 5 together to complete the production of the air column bag.

[0028] The usage process of this utility model is as follows:

[0029] When the air column bag body 3 is punctured by a sharp object, an opening appears on the surface of the air column bag body 3. At this time, the air inside the air column bag body 3 leaks out through the opening. When the air inside the air column bag body 3 leaks out, the insulating plate 4 is affected by the air pressure difference between the air inside the air column bag body 3 and the outside air, which applies a pushing force to the insulating plate 4, causing the insulating plate 4 to deform towards the inner wall of the air column bag body 3 and stick to the inner wall of the air column bag body 3. At this time, the opening on the air column bag body 3 is blocked by the insulating plate 4, so the air inside the air column bag body 3 cannot leak out through the opening. Compared with the current air column bag, this structure can block the opening on the air column bag body 3 in time, prevent the continuous leakage of air inside the air column bag body 3, and avoid the situation where the air column bag body 3 loses its buffering capacity after the air inside the air column bag body 3 has leaked out. It preserves the buffering capacity of the air column bag body 3 after being punctured as much as possible.

[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
