Description

Technical Field

[0001] This utility model relates to the field of air column bag technology, and in particular to a spliced ​​air column bag. Background Technology

[0002] Air column bags are inflatable cushioning packaging materials made from nylon and polyethylene composite film. They consist of multiple independent air columns connected together by a heat-sealing process, forming a honeycomb-like column structure. Their working principle is to use the elasticity of the air columns to form a buffer layer, effectively absorbing external impacts during transportation and providing reliable protection for fragile items such as electronic products, glassware, and precision instruments.

[0003] Existing interlocking air column bags typically use heat-sealed connection areas or adhesive layers on the edges of individual air column bags to splice multiple air column bag units along the edges to form a package of the required size. Traditional splicing methods rely solely on heat sealing of a single layer of film or planar adhesive. When subjected to vibration, compression, or impact loads during transportation, the splice joints are prone to tearing due to stress concentration. Especially after the air column is inflated, the edge connection areas of adjacent air column bags are in a tense state. If an external impact force is encountered at this time, the weak splice parts cannot withstand the instantaneous stress change, causing the air column bags to separate or break, thus losing the overall cushioning protection function. This not only increases the risk of damage to fragile items during transportation but also greatly reduces the reliability and reusability of the packaging material.

[0004] Therefore, it is necessary to invent a modular air column bag to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a spliced ​​air column bag to solve the problem mentioned in the background art. Existing spliced ​​air column bags typically use heat-sealed connection areas or adhesive layers on the edges of individual air column bags to splice multiple air column bag units along the edges to form a packaging unit of the required size. Traditional splicing methods rely solely on heat sealing of a single-layer film or planar adhesive bonding. When subjected to vibration, compression, or impact loads during transportation, the splice joints are prone to tearing due to stress concentration. Especially after the air column is inflated, the edge connection areas of adjacent air column bags are under tension. If subjected to external impact, the weak splice joints cannot withstand instantaneous stress changes, leading to separation or damage between pairs of air column bags, thus losing the overall cushioning and protection function. This not only increases the risk of damage to fragile items during transportation but also significantly reduces the reliability and reusability of the packaging material.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a splicing air column bag, comprising a first fixing plate and a second fixing plate, wherein two of each of the first fixing plate and the second fixing plate are symmetrically arranged, T-shaped grooves are symmetrically opened on both sides of the first fixing plate, and T-shaped sliders are symmetrically fixedly connected to both sides of the second fixing plate, wherein the T-shaped sliders are correspondingly arranged with the T-shaped grooves, and the T-shaped sliders are slidably connected to the inner side of the T-shaped grooves; The first fixing plate and the second fixing plate are evenly provided with multiple grooves on their sides, and the air column bag body is provided inside the grooves. A thickened layer is fixedly connected to the rear end of the air column bag body, and the thickened layer is arranged correspondingly to the groove.

[0007] As a preferred embodiment, two first magnetic absorbing pieces are symmetrically arranged on the inner side of the groove, and two second magnetic absorbing pieces are symmetrically arranged on the rear end of the thickened layer, with the second magnetic absorbing pieces corresponding to the first magnetic absorbing pieces.

[0008] As a preferred embodiment, a connecting pipe is provided between each pair of air column bag bodies. Two connecting pipes are symmetrically arranged and each is connected to the air column bag bodies on both sides. The material of the connecting pipe is the same as that of the air column bag body.

[0009] As a preferred embodiment, an inflation port is provided on the side of one side of the air column bag body, the inflation port is connected to the air column bag body, and a sealing plug is provided on the outside of the inflation port.

[0010] As a preferred embodiment, the front end of the air column bag body is provided with a wear-resistant layer, which is sprayed onto the surface of the air column bag body.

[0011] As a preferred embodiment, the first fixing plates are arranged opposite each other in pairs, and the second fixing plates are slidably connected to the inner side of the first fixing plates from both sides by means of T-shaped sliders.

[0012] The technical effects and advantages of this utility model are as follows: 1. This utility model provides a first fixing plate and a second fixing plate. Multiple air column bag bodies are provided on one side of both the first fixing plate and the second fixing plate. T-shaped grooves are provided on both sides of the first fixing plate, and T-shaped sliders are provided on both sides of the second fixing plate. The T-shaped sliders can be slidably connected to the inner side of the T-shaped grooves, which facilitates quick splicing and effectively improves the stability of splicing multiple air column bag bodies individually. It avoids tearing caused by compression and other problems and facilitates subsequent use. 2. This utility model provides a connecting pipe between two air column bag bodies, allowing them to communicate with each other. Each air column bag body has an inflation port on its side, and a sealing plug is provided on the outside of the inflation port, enabling the air column bag body to be inflated quickly. At the same time, if one of the multiple air column bag bodies leaks air, the other air column bag bodies can replenish air to the inside of the air column bag body through the connecting pipe, reducing leakage and increasing the normal use time.

[0015] 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.

[0016] Please see the appendix Figure 1 - Appendix Figure 4 A spliced ​​air column bag includes a first fixing plate 1 and a second fixing plate 3. Two first fixing plates 1 and two fixing plates 3 are symmetrically arranged. The first fixing plates 1 are arranged opposite each other. The second fixing plates 3 are slidably connected to the inner side of the first fixing plate 1 from both sides by T-shaped sliders 31. T-shaped grooves 11 are symmetrically opened on both sides of the first fixing plate 1. T-shaped sliders 31 are symmetrically fixedly connected to both sides of the second fixing plate 3. The T-shaped sliders 31 are correspondingly arranged with the T-shaped grooves 11. The T-shaped sliders 31 are slidably connected to the inner side of the T-shaped grooves 11. The first fixing plate 1 and the second fixing plate 3 have a plurality of grooves 12 evenly provided on their sides. An air column bag body 2 is provided inside the groove 12. A thickening layer 24 is fixedly connected to the rear end of the air column bag body 2. The thickening layer 24 is provided corresponding to the groove 12.

[0017] Specifically, by setting a first fixing plate 1 and a second fixing plate 3, multiple air column bag bodies 2 are provided on one side of both the first fixing plate 1 and the second fixing plate 3. T-shaped grooves 11 are provided on both sides of the first fixing plate 1, and T-shaped sliders 31 are provided on both sides of the second fixing plate 3. The T-shaped sliders 31 can be slidably connected to the inner side of the T-shaped grooves 11, thereby facilitating quick splicing and subsequent use.

[0018] Please see the appendix Figure 2 and Figure 4 Two first magnetic absorbing pieces 13 are symmetrically arranged inside the groove 12, and two second magnetic absorbing pieces 25 are symmetrically arranged at the rear end of the thickened layer 24. The second magnetic absorbing pieces 25 are arranged corresponding to the first magnetic absorbing pieces 13.

[0019] Specifically, the first magnetic absorbing piece 13 and the second magnetic absorbing piece 25 are made of neodymium iron boron magnetic strips with a thickness of less than 1 mm. When the air column bag body 2 needs to be placed inside the groove 12, the second magnetic absorbing piece 25 can be brought close to the first magnetic absorbing piece 13, so that the thickened layer 24 will be attracted to the groove 12, which improves the stability of use and facilitates quick assembly.

[0020] Please see the appendix Figure 1 A connecting pipe 21 is provided between each pair of air column bag bodies 2. Two connecting pipes 21 are symmetrically arranged and are connected to the air column bag bodies 2 on both sides. The material of the connecting pipe 21 is the same as that of the air column bag body 2.

[0021] Specifically, by setting up connecting pipes 21, two connecting pipes 21 are symmetrically arranged and are connected to the air column bag bodies 2 on both sides respectively, so that gas can be conducted among multiple air column bag bodies 2. If one of the multiple air column bag bodies 2 leaks, the other air column bag bodies 2 can be replenished with gas through the connecting pipes 21, which reduces the leakage and increases the normal use time.

[0022] Please see the appendix Figure 1 An inflation port 22 is provided on the side of one side of the air column bag body 2. The inflation port 22 is connected to the air column bag body 2. A sealing plug 23 is provided on the outside of the inflation port 22.

[0023] Specifically, by setting an inflation port 22, which is connected to the air column bag body 2, air can be inflated into the inside of the air column bag body 2 through the inflation port 22. Multiple air column bag bodies 2 are connected to each other through a connecting pipe 21, so air can be effectively inflated into multiple air column bag bodies 2 through the inflation port 22. By setting a sealing plug 23, which is inserted into the inside of the inflation port 22, the inflation port 22 can be effectively sealed to prevent air leakage. When it is necessary to deflate the air column bag body 2, the sealing plug 23 can be pulled out from the inside of the inflation port 22, and the gas in the entire air column bag body 2 can be discharged from the inflation port 22, which is convenient to use.

[0024] Please see the appendix Figure 4 The front end of the air column bag body 2 is provided with a wear-resistant layer 26, which is sprayed onto the surface of the air column bag body 2.

[0025] Specifically, a wear-resistant layer 26 is sprayed onto the front end of the air column bag body 2. The wear-resistant layer 26 is made of polyurethane and nano-silica. The nano-silica particles are uniformly dispersed in the polyurethane matrix to form a micro-hard skeleton. At the same time, the polyurethane can maintain flexibility, thereby effectively improving the scratch resistance of the air column bag body 2 and increasing the life of the air column bag body 2.

[0026] The working principle of this utility model is as follows: In specific use, the air column bag body 2 is first placed on the side of the first fixing plate 1 and the second fixing plate 3. The second magnetic suction piece 25 can approach the first magnetic suction piece 13, so that the thickened layer 24 will be attracted to the groove 12, which improves the stability of use and facilitates quick assembly. The air column bag body 2 is quickly assembled with the first fixing plate 1 and the second fixing plate 3. Both sides of the first fixing plate 1 are provided with T-shaped grooves 11, and the sides of the second fixing plate 3 are respectively provided with T-shaped sliders 31. The T-shaped sliders 31 can be slidably connected to the inner side of the T-shaped grooves 11, and the two second fixing plates 3 can be slidably set on the sides of the two first fixing plates 1 to form a rectangle. This effectively improves the stability of the individual splicing of multiple air column bag bodies 2, avoids tearing caused by compression and other problems, and facilitates subsequent use.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
