Description

Technical Field

[0001] The utility model relates to the technical field of bubble bags, in particular to a pressure-resistant inflatable double-layer bubble bag. Background Art

[0002] Bubble bags are mainly made of high-pressure polyethylene bubble film, which is cut into the required bag size and then processed by a bubble film special bag making machine {hot drying and hot cutting bag making machine}. They are mainly used for electronic product cushioning packaging, plastic products, metal products, ceramic products, glass products and other products that require cushioning protection. Logistics and transportation protection;

[0003] The existing authorization announcement number is "CN217970790U" and a pressure-resistant inflatable double-layer bubble bag, comprising a first bubble bag, the first bubble bag is connected to the second bubble bag through an air duct, the second bubble bag is connected to the third bubble bag through the air duct, the third bubble bag is connected to the fourth bubble bag through the air duct, the fourth bubble bag is connected to the fifth bubble bag through the air duct, and the fifth bubble bag is connected to the sixth bubble bag through the air duct. The pressure-resistant inflatable double-layer bubble bag is convenient for users to inflate by themselves, and is convenient for transportation and storage. Moreover, when a single bubble bag is damaged, it will not cause other connected bubble bags to leak at the same time, thereby improving the service life of the utility model. At the same time, through ten one-way connected independent bubble bags, when the bubble bag is stepped on and the air pressure in the bubble bag is too high, the gas can be introduced into other bubble bags to avoid being stepped on and exploded, thereby improving the risk resistance of the bubble bag.

[0004] However, in order to ensure the safety of goods during transportation, the gas inside each of these air bags is in a relatively saturated state. If during the placement process, these air bags are subjected to the instantaneous pressure brought by the full weight of the human body, these air bags will still burst and will not be able to relieve pressure well. Utility Model Content

[0005] The purpose of the utility model is to provide a pressure-resistant inflatable double-layer bubble bag to solve the existing problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pressure-resistant inflatable double-layer bubble bag, comprising a lower bubble bag, a ventilation tube is provided on the top of the lower bubble bag, an upper bubble bag is provided on the top of the ventilation tube, a first connecting tube is provided between the two groups of the lower bubble bags and the two groups of the upper bubble bags, connecting hoses are provided at the top and bottom of the upper bubble bags and the ventilation tubes, a second connecting tube is provided at the connecting hose, a separator tube is provided between the two groups of the second connecting tubes, a mounting groove is provided on one side of the separator tube, and a sealing film is provided inside the mounting groove.

[0007] Preferably, the installation groove and the sealing film are both made of an arc-shaped structure, and when they are subsequently subjected to a greater pressure, they are guided so that the air pressure impacts and ruptures the sealing film, thereby releasing the pressure.

[0008] Preferably, a gas nozzle is provided on one side of the upper bubble bag, and a sealing plug is provided inside the gas nozzle to replenish the gas inside the lower bubble bag and the upper bubble bag and prevent gas leakage.

[0009] Preferably, ventilation tubes are provided between the multiple groups of upper bubble bags and the multiple groups of lower bubble bags, and the multiple groups of lower bubble bags and the multiple groups of upper bubble bags are interconnected, so that the gases inside the lower bubble bags and the upper bubble bags can circulate with each other, facilitating their own pressure relief work.

[0010] Preferably, the upper bubble bag, the ventilation tube and the lower bubble bag form a triangular structure to ensure the stability between the lower bubble bag and the upper bubble bag, so that the air bag can be tightly attached to the surface of the object to prevent it from moving at will and causing a gap between the object.

[0011] Preferably, the separation tube is made of plastic material, and is connected to the interior of the upper bubble bag via a second connecting tube and a connecting hose, so that subsequent gas can enter the interior of the separation tube for pressure relief.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the pressure-resistant inflatable double-layer bubble bag;

[0013] With the cooperation of the lower bubble bag, the ventilation tube, the first connecting tube and the upper bubble bag, the stability between the lower bubble bag and the upper bubble bag can be ensured during the use of the air bag, so that the air bag can be tightly attached to the object during transportation to prevent the object from having gaps and shaking. At the same time, after being subjected to pressure, the ventilation tube will also have a certain bend to help buffer. At the same time, when the lower bubble bag and the upper bubble bag are subjected to a greater pressure for a moment, with the cooperation of the installation groove, the sealing film, the second connecting tube, the connecting hose and the separating tube, the installation groove will rupture. At this time, the gas flows into the interior of the separating tube, thereby releasing the pressure, reducing the air pressure inside the lower bubble bag and the upper bubble bag, and effectively avoiding the lower bubble bag and the upper bubble bag from rupturing.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

A first connecting tube 3 is provided between the two groups of lower bubble bags 1 and the two groups of upper bubble bags 9. Connecting hoses 7 are provided at the top and bottom of the upper bubble bag 9 and the ventilation pipe 2. A second connecting tube 6 is provided at the connecting hose 7. A separating tube 8 is provided between the two groups of second connecting tubes 6. The separating tube 8 is made of plastic material. The separating tube 8 is connected to the interior of the upper bubble bag 9 through the second connecting tube 6 and the connecting hose 7, so that the subsequent gas can enter the separating tube 8 for pressure relief. A mounting groove 4 is provided on one side of the separating tube 8. A sealing film 5 is provided inside the mounting groove 4. Both the mounting groove 4 and the sealing film 5 are made of an arc structure. When they are subjected to a large pressure in the future, they are guided so that the air pressure can impact and rupture the sealing film 5, thereby releasing the pressure.

[0020] Working principle: In the process of transporting some fragile or electronic objects, the air bags are wrapped around the outer wall of the objects to protect the objects. If the objects are subjected to external pressure, the upper bubble bag 9 and the lower bubble bag 1 will be deformed to a certain extent, thereby buffering the pressure. When the pressure is high, the ventilation tube 2 will be bent to a certain extent to help the lower bubble bag 1 and the upper bubble bag 9 to buffer. If the air bags are stepped on by the staff during the packaging process, the pressure inside the lower bubble bag 1 and the upper bubble bag 9 will increase instantly. At this time, the sealing film 5 will rupture under the influence of pressure, and then the gas inside the lower bubble bag 1 and the upper bubble bag 9 will enter the interior of the separation tube 8, thereby releasing the pressure inside the lower bubble bag 1 and the upper bubble bag 9, thereby preventing the lower bubble bag 1 and the upper bubble bag 9 from rupturing.
