Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and mainly to a quick-release inflatable cushioning bag. Background Technology

[0002] Existing inflatable cushioning bags, when used inside containers as cushioning and shock-absorbing materials for cargo, are mostly used in the gaps between goods, the side walls of the container, and the container doors. Furthermore, when using inflatable cushioning bags, it is necessary to use straps to fix the inflatable cushioning bags to the container to ensure that the inflatable cushioning bags do not shake. In addition, each inflatable bag needs to be inflated individually and loaded into the container separately, making the whole process very inconvenient and cumbersome.

[0003] To overcome the inconvenience of installing and disassembling traditional inflatable cushioning bags, a quick-installation design concept was introduced. Quick-installation inflatable cushioning bags, through a special structural design and connection method, allow for rapid installation onto products and convenient, quick disassembly upon arrival at the destination, significantly improving packaging and unpacking efficiency and saving time and labor costs. This quick-installation design not only meets the needs of modern logistics for rapid turnover but also enhances the user experience, thus possessing broad application prospects in the market. Quick-installation inflatable cushioning bags are a new type of packaging product developed against the backdrop of continuous advancements in cushioning packaging technology, designed to address the problems associated with traditional packaging materials and ordinary inflatable bags.

[0004] Utility model patent application CN201320712585.0 discloses a one-piece inflatable bag, which is composed of multiple individual inflatable bags connected together. Each individual inflatable bag is equipped with a one-way valve, and the air inlet of the one-way valve is connected to a continuous inflation channel. Adjacent individual inflatable bags are connected by a point-discontinuity connection. The individual inflatable bags are surrounded by heat-sealed lines on all four sides of two layers of plastic film; the inflation channel is surrounded by two parallel heat-sealed lines located on one side of the two layers of plastic film. This utility model has a simple structure and is easy to manufacture; when not inflated, it can be rolled up and packaged as a whole, saving storage space; after inflation with simple equipment, the point-discontinuity lines allow the individual inflatable bags to be separated without complicated machinery, making them easy to separate and convenient to operate.

[0005] However, the applicant found that there are still some shortcomings: 1. The flexibility and scope of application of the one-piece inflatable bags are still limited. The number of inflatable bags cannot be increased or decreased arbitrarily according to different sizes of products, so it is necessary to purchase inflatable bags of various sizes, which increases the cost and management complexity; 2. The insulated bags are not connected, so they cannot be inflated at the same time, which increases the operation time cost.

[0006] Therefore, there is an urgent need for an inflatable bag that offers cushioning advantages, all-around protection, and the convenience of a quick-assembly structure. Utility Model Content

[0007] To address the above issues, an inflatable bag with good overall stability, protection, and convenient assembly and disassembly has been developed. The designed inflation channels allow individual inflatable bags to be arbitrarily disassembled and connected, and the gas between the individual inflatable bags can be connected. This not only improves the applicability of the inflatable bag but also greatly improves the installation efficiency.

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0056] Example 1:

[0057] like Figures 1 to 14 As shown, a quick-release inflatable cushioning bag includes:

[0058] At least two interconnected inflatable bags 1;

[0059] The inflatable bag 1 includes a single inflatable bag 11 and an inflation channel 12;

[0060] The single inflatable bag 11 is designed for inflation, and the inflation channels 12 are located on both sides of the single inflatable bag 11 in the width direction.

[0061] A closing valve 21 is provided on the inflation channel 12 on one side of the single inflatable bag 11, and a venting valve 22 is provided on the inflation channel 12 on the other side of the single inflatable bag 11. Two adjacent sets of inflatable bags 1 are connected to the venting valve 22 through the corresponding closing valve 21, and are connected to the inflation channel 12.

[0062] The closed valve 21 includes a valve port 210, a vent ring 211, a spring base 212, a valve spring 213, and a valve closing block 214;

[0063] The valve port 210 has a spiral thread 216 on the outer surface end, and an annular groove 200 is also provided on the top of the valve port 210.

[0064] The venting ring 211 is fixedly connected to the inner cavity of the valve port 210. The bottom of the spring base 212 is fixedly connected to the top of the venting ring 211. The top of the spring base 212 is fixedly connected to the bottom of the valve spring 213. The top of the valve spring 213 is fixedly connected to the bottom of the valve closing block 214. The valve closing block 214 is elastically extended and retracted by the valve spring 213.

[0065] The valve closing block 214 is cylindrical in shape, and its top abuts against the valve opening 210. The top of the valve closing block 214 is also provided with a protruding cylindrical block 215. When the valve closing block 214 abuts against the valve opening 210, it seals the valve opening 210.

[0066] The ventilation valve 22 includes a ventilation port, a ventilation ring 221, a ventilation rod 222, a fixing block 228, a ventilation spring 229, and a connecting sleeve 223;

[0067] The vent is inserted into the annular groove 200, and the vent ring 221 is fixedly connected to the inner cavity of the vent.

[0068] One end of the ventilation rod 222 is fixedly connected to the top of the ventilation ring 221, and the other end of the ventilation rod 222 is in contact with and squeezed against the top of the cylindrical block 215 to open the valve port 210.

[0069] The fixing block 228 is arranged in a ring shape and is fixedly connected to the inside of the vent valve 22. The center of the fixing block 228 passes through the vent rod 222.

[0070] The ventilation spring 229 is directly pressed between the fixed block 228 and the ventilation rod 222. The end of the ventilation rod 222 is provided with a disc portion 2220 that limits the ventilation spring 229. When the ventilation rod 222 abuts against the cylindrical block 215 through the disc portion 2220, it presses the ventilation spring 229 to push the ventilation ring 221 inward, thus opening the ventilation valve 22. The ventilation ring 221 is elastically extended and retracted by the ventilation spring 229.

[0071] The connecting sleeve 223 is coaxially sleeved on the outside of the vent. The inner surface of the connecting sleeve 223 is provided with a threaded groove 224, which is engaged with the thread 216. By rotating the connecting sleeve 223, the vent and the valve port 210 are connected.

[0072] In addition, a rubber ring 226 is provided inside the connecting sleeve 223, and the rubber ring 226 abuts against the limiting block 227 that restricts the position of the connecting sleeve 223. After the connecting sleeve 223 rotates into place, the connection between the vent and the valve port 210 is completed. At this time, the rubber ring 226 just abuts and presses against the limiting block 227, so that the rubber ring 226 seals the rotating part of the connecting sleeve 223.

[0073] The single inflatable bag 11 also includes a sealing cap 3, which covers the valve port 210 and the vent, and a rubber pad is provided on the lower surface of the sealing cap 3.

[0074] It should be noted that the single inflatable bag 11 consists of an outer bag and an inner bag. The outer bag is made of polyethylene or polypropylene woven fabric. This material has good wear resistance and tear resistance, and can withstand various external impacts during transportation, protecting the inner inflatable bag from damage. It can also resist external environmental factors and ensure the stability of the inflatable bag during long-term use. The inner bag is made of polyethylene tubular film or sheet film heat-sealed. This material has excellent airtightness, excellent softness and elasticity, and can well adapt to the expansion and deformation after inflation. It can also effectively buffer energy when subjected to external impacts, protecting the packaged items.

[0075] Secondly, it should be noted that the specific connection structure between the closed valve 21 and the vent valve 22 involves inserting the vent into the annular groove 200, with the vent rod 222 and the cylindrical block 215 engaging and pressing against each other. Then, the connecting sleeve 223 is screwed onto the valve port 210 using the threads 216 and grooves 224, gradually bringing the valve port 210 and the vent closer together. This causes the vent rod 222 and the valve closing block 214 to engage and push against each other, which is then pushed by the vent spring 229 and the valve spring 213. The elastic setting allows the valve closing block 214 and the vent ring 221 to move inward, thereby opening the sealing port to allow gas to flow. When the connecting sleeve 223 loosens the threads 216 and the grooves 224 on the valve port 210, the valve port 210 gradually separates from the vent. Then, the vent rod 222 stops pressing against the valve closing block 214, and the vent ring 221 and the valve closing block 214 block the valve port 210 and the vent through the rebound force of the vent spring 229 and the valve spring 213, thereby preventing gas leakage.

[0076] Two sets of adjustment straps 13 and connecting straps 14 are also fixedly connected to both sides of the single inflatable bag 11;

[0077] The adjusting belt 13 is installed on one side of the single inflatable bag 11, and the connecting belt 14 is installed on the other side of the single inflatable bag 11.

[0078] The adjusting belt 13 is also provided with a U-shaped buckle 131. The adjusting belt 13 passes through the U-shaped buckle 131 and is connected to the U-shaped buckle 131 by friction of the adjusting belt 13 itself.

[0079] One end of the shaped buckle 131 is fixedly connected to a recessed buckle 132, and a groove 133 is provided in the recessed buckle 132.

[0080] A buckle 141 is fixedly connected to the connecting band 14. The buckle 141 is matched with the groove 133. The buckle 141 is arranged in a mountain shape. The buckle 141 can be elastically inserted into the groove 132 for engagement.

[0081] It should be noted that the cooperation between the D-shaped buckle 131 and the adjusting belt 13 is that the adjusting belt 13 is adjusted by the D-shaped buckle 131, and the length can be flexibly adjusted according to actual needs to adapt to different packaging requirements. The adjusting belt 13 is adjusted to a suitable length by the D-shaped buckle 131 to ensure the stability of the item connection.

[0082] Secondly, it should be noted that the tight fit between the recessed buckle 132 and the protruding buckle 141 can firmly connect multiple individual air bags 1 together, preventing them from accidentally loosening or slipping during use.

[0083] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
