Description

Technical Field

[0001] This utility model relates to the field of multi-level cushioning air column bags, and in particular to a multi-level cushioning air column bag. Background Technology

[0002] Air column bags, also known as cushioning air column bags, inflatable bags, bubble column bags, and columnar inflatable bags, are a new type of packaging material in the 21st century that uses natural air to fill the bags. They provide long-term shock protection during storage and transportation, and the air column-style full-coverage cushioning protection minimizes product transportation loss.

[0003] The applicant discovered a Chinese patent, "A Multi-Level Cushioning Air Column Bag," with publication number CN221342065U. This patent primarily protects the air column bag by using double-sided adhesive strips to bond the protective air column sheet to the bag body, preventing it from being directly punctured and collapsing, thus failing to provide cushioning protection for precision items. However, this patent only achieves protection through the superposition of the protective air column sheet and the bag body, without forming a hierarchical system of gas cushioning, elastic material cushioning, and structural cushioning. Furthermore, it lacks specialized components for corner and lateral impacts, relying solely on vertical cushioning of the air column body. In actual use, when faced with impacts of varying intensities, energy cannot be dissipated in an orderly manner, increasing the risk of damage to precision items. The lack of elastic material to soften the contact force makes the bag body susceptible to direct damage from sharp objects, leading to cushioning failure. Additionally, corners are prone to concentrated stress during transportation, causing the bag body to rupture directly and precision items to break at the corners. Therefore, we propose a multi-level cushioning air column bag. Utility Model Content

[0004] The purpose of this invention is to provide a multi-level cushioning air column bag to solve the problems mentioned in the background art, which only achieve protection by superimposing protective air column sheets and the air column bag body, without forming a graded system of gas cushioning, elastic material cushioning, and structural cushioning, and without setting up special components for corner and lateral impacts, relying only on the vertical cushioning of the air column body. In actual use, when faced with impacts of different intensities, energy cannot be dissipated in an orderly manner, increasing the risk of damage to precision items. In addition, the lack of elastic material to soften the contact force makes the air column bag body easy to be directly damaged by the squeezing of sharp objects, resulting in cushioning failure. Furthermore, during transportation, the corners are prone to concentrated stress, causing the air column bag body to rupture directly, resulting in damage to the corners of precision items.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-level cushioning air column bag, comprising an elastic frame, wherein the elastic frame is provided with a multi-level cushioning assembly, the multi-level cushioning assembly comprising an inflation tube, a cushioning pad, a cushioning layer, a silicone gasket, and elastic rubber strips, the inflation tube being connected to the air column body via an air inlet tube, a sealing plug being inserted into the inner wall of the left end of the inflation tube, the inflation tube being fixedly installed on the upper inner wall of the elastic frame, and four sets of elastic rubber strips being provided, the four sets of elastic rubber strips being fixedly installed at the four corners of the outer wall of the elastic frame respectively.

[0006] As a preferred embodiment, the air intake pipe is provided in multiple sets, and each set of air intake pipes is fixedly connected to the bottom outer wall of the inflation pipe. The air column body and the buffer pad are also provided in multiple sets.

[0007] As a preferred embodiment, the tops of the multiple sets of air column bodies are respectively fixedly connected to the lower ends of the multiple sets of air inlet pipes, the multiple sets of air column bodies are fixedly connected at equal intervals to the inner bottom wall of the elastic frame, and the multiple sets of buffer pads are respectively fixedly installed on the outer walls of the multiple sets of air column bodies.

[0008] As a preferred embodiment, multiple sets of buffer layers are fixedly connected to the corresponding sides of the air column bodies between each pair. Two sets of silicone pads are provided, with one side of each set of silicone pads fixedly connected to the inner walls of the left and right sides of the elastic frame, the other side of the left silicone pad being fixedly connected to the outer left side of the left air column body, and the other side of the right silicone pad being fixedly connected to the outer right side of the right air column body.

[0009] As a preferred embodiment, a locking component is provided on the outer wall of the elastic frame. The locking component includes a rough surface block and a hook surface block. Two sets of rough surface blocks and hook surface blocks are provided. The two sets of rough surface blocks and hook surface blocks are respectively fixedly connected to the upper and lower outer walls of the front of the elastic frame.

[0010] As a preferred embodiment, release film is provided on the outer wall of both sets of hook blocks, and connecting blocks are fixedly connected to the left and right outer walls of the front of the elastic frame. A locking block is fixedly connected to the front of the right connecting block, and a locking groove is opened on the front of the left connecting block. The locking block is adapted to the locking groove.

[0011] The technical effects and advantages of this utility model are as follows: 1. Through the design of multi-level buffer components, a three-level protection system can be formed by combining the air column body, buffer pad, buffer layer and elastic rubber strip. When subjected to external impact, the elastic rubber strip first absorbs the stress concentrated at the four corners, the air column body disperses the main impact force through air compression, the buffer pad and buffer layer further soften the contact force, thereby improving the impact resistance, the silicone pad enhances the lateral buffering and prevents the air column body from deforming due to lateral compression, and the buffer layer restricts the lateral displacement of the air column body, ensuring that both vertical and lateral impacts can be effectively resolved. It is especially suitable for all-round protection of irregularly shaped objects. 2. Through the locking components, the rough surface block and the hook surface block work together to achieve quick and easy pasting and fixing of items after the elastic frame is wrapped. This can be done without tools, effectively improving packaging efficiency. The mechanical locking structure composed of the connecting block, locking block and locking groove can further enhance the connection strength of the left and right sides of the elastic frame on the basis of the initial fixation of the rough surface block and the hook surface block, forming a multi-dimensional locking from top to bottom and left to right, preventing the packaging from accidentally falling apart during transportation.

[0014] 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.

[0015] Please see the appendix Figure 1 - Appendix Figure 5 A multi-stage cushioning air column bag includes an elastic frame 1. The elastic frame 1 is internally provided with a multi-stage cushioning component 2. The multi-stage cushioning component 2 includes an inflation tube 201, a cushioning pad 204, a cushioning layer 205, a silicone pad 207, and an elastic rubber strip 208. The inflation tube 201 is connected to the air column body 203 through an air inlet tube 202. A sealing plug 206 is inserted and connected to the inner wall of the left end of the inflation tube 201. The inflation tube 201 is fixedly installed on the upper inner wall of the elastic frame 1. Four sets of elastic rubber strips 208 are provided, and the four sets of elastic rubber strips 208 are respectively fixedly installed at the four corners of the outer wall of the elastic frame 1. Multiple sets of air inlet tubes 202 are provided, and all sets of air inlet tubes 202 are fixedly connected to the bottom outer wall of the inflation tube 201. Multiple sets of air column body 203 and cushioning pad 204 are also provided.

[0016] The elastic frame 1 serves as the main skeleton of the air column bag, maintaining the overall three-dimensional structure and preventing the air column body 203 from deforming and collapsing due to inflation. Its own elastic material can absorb external impact force, and in particular, when combined with the elastic rubber strips 208 at the four corners, it can enhance the corners' resistance to compression. The elastic frame 1 can fix the inflation tube 201 and silicone gaskets 207 and other components, ensuring the stability of each component.

[0017] The tops of multiple air column bodies 203 are fixedly connected to the lower ends of multiple air inlet pipes 202. Multiple air column bodies 203 are fixedly connected at equal intervals to the inner bottom wall of the elastic frame 1. Multiple buffer pads 204 are fixedly installed on the outer walls of multiple air column bodies 203. Multiple buffer partitions 205 are fixedly connected to the corresponding sides of two air column bodies 203. Two sets of silicone pads 207 are provided. One side of the two sets of silicone pads 207 are fixedly connected to the inner walls of the left and right sides of the elastic frame 1. The other side of the left silicone pad 207 is fixedly connected to the left outer wall of the left air column body 203, and the other side of the right silicone pad 207 is fixedly connected to the right outer wall of the right air column body 203.

[0018] The inflation tube 201 is connected to an external inflation device. It inflates multiple air column bodies 203 at the same time through the air inlet tube 202, realizing the convenience of one-button inflation. The inner wall of the inflation tube 201 is fitted with a sealing plug 206. After inflation, the opening of the inflation tube 201 is blocked by the sealing plug 206 to prevent gas leakage and maintain the pressure of the air column body 203.

[0019] Specifically, through the multi-level buffer assembly 2, a three-level protection system can be formed by combining the air column body 203, buffer pad 204, buffer partition 205, and elastic rubber strip 208, which includes gas buffering, elastic material buffering, and structural buffering. When an external impact occurs, the elastic rubber strip 208 absorbs the concentrated stress at the four corners, the air column body 203 disperses the main impact force through air compression, the buffer pad 204 and buffer partition 205 soften the contact force to improve impact resistance, the silicone pad 207 enhances lateral buffering and prevents the air column body 203 from being deformed laterally by compression, and the buffer partition 205 restricts the lateral displacement of the air column body 203, thus effectively mitigating vertical and lateral impacts. It is suitable for all-round protection of irregularly shaped objects.

[0020] Please see the appendix Figure 1 Appendix Figure 5 and appendix Figure 6 A locking component 3 is provided on the outer wall of the elastic frame 1. The locking component 3 includes a rough surface block 301 and a hook surface block 302. There are two sets of rough surface blocks 301 and hook surface blocks 302. The two sets of rough surface blocks 301 and hook surface blocks 302 are respectively fixedly connected to the upper and lower outer walls of the front of the elastic frame 1. A release film 303 is provided on the outer wall of the two sets of hook surface blocks 302. A connecting block 304 is fixedly connected to the outer walls of the left and right sides of the front of the elastic frame 1. A locking block 305 is fixedly connected to the front of the right connecting block 304. A locking groove 306 is opened on the front of the left connecting block 304. The locking block 305 is adapted to the locking groove 306.

[0021] Release film 303 covers the surface of hook block 302, which can prevent the adhesive from adhering to dust and impurities during storage or transportation, ensuring reliable adhesion during use. In food packaging scenarios, release film 303 can prevent hook block 302 from directly contacting external contaminants, meeting the hygiene requirements for food contact materials.

[0022] Specifically, through the locking component 3, the rough surface block 301 and the hook surface block 302 work together to achieve quick pasting and fixing of the elastic frame 1 after wrapping the item, without the need for tools, thus improving packaging efficiency. The connecting block 304, the locking block 305 and the locking groove 306 form a mechanical locking structure. On the basis of the initial fixing of the rough surface block 301 and the hook surface block 302, the connection strength of the left and right sides of the elastic frame 1 is enhanced, forming a multi-dimensional locking from top to bottom and left to right, preventing the packaging from accidentally falling apart during transportation.

[0023] Working principle of this utility model: This utility model is a multi-level cushioning air column bag. First, the worker takes out the multi-level cushioning air column bag, tears off the release film 303 on the outer wall of the hook block 302, and then places the item to be packaged in the elastic frame 1. Using the cooperation of the rough block 301 and the hook block 302, the initial pasting and fixing of the item after the elastic frame 1 wraps the item is quickly completed. Next, the locking block 305 on the right connecting block 304 is inserted into the locking groove 306 on the left connecting block 304 to form a multi-dimensional locking from top to bottom and left to right, ensuring the packaging is stable. After the item is fixed, the worker connects the inflation pipe 201 to an external inflation device and inflates multiple sets of air column bodies 203 through the air inlet pipe 202. After the air column bodies 203 are fully inflated, the sealing plug 206 is inserted into the left end of the inflation pipe 201. The inner wall blocks the pipe openings to prevent gas leakage and maintain the air column pressure. During transportation, when the multi-stage buffer air column bag is subjected to external impact, the elastic rubber strips 208 at the four corners of the elastic frame 1 first absorb the concentrated stress. Then, the air column body 203 disperses the main impact force through air compression. At the same time, the buffer pad 204 and the buffer partition 205 further soften the contact force and improve the overall impact resistance. The silicone pad 207 enhances lateral buffering and prevents the air column body 203 from deforming due to lateral compression. The buffer partition 205 restricts the lateral displacement of the air column body 203, ensuring that both vertical and lateral impacts can be effectively resolved, achieving all-round protection for the items. After arriving at the destination, the staff can easily take out the items by separating the locking block 305 and the locking groove 306, and tearing open the rough surface block 301 and the hook surface block 302.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
