[0023] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "provided with", "sheathed / connected", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] A portable air column bag, as Figures 1 - 4 shown, includes an air column bag body. The air column bag body includes a plurality of integrally formed air column strips 1 and a connecting strip 2. The connecting strip 2 is located above the plurality of air column strips 1. An air inlet 3 communicating with the inside of the air column strip 1 is provided in the connecting strip 2, and a one-way valve is provided in the air column strip 1. A connecting channel 4 is opened on the side wall of the connecting strip 2, and an identification strip for controlling the opening and closing of the air inlet 3 is provided in the connecting channel 4;

[0025] such as Figures 1 - 4As shown, two sealing strips 5 symmetrically arranged are fixedly connected in the connecting channel 4, the identification strip includes an integrally formed identification portion 6 and a sliding portion 7, the identification portion 6 is slidably connected between the two sealing strips 5 and fits with the sealing strips 5, an opening 8 for the sliding portion 7 to be inserted is provided on the side of the air inlet 3 facing the connecting channel 4, a limiting block 14 is integrally formed on the side wall of the sliding portion 7, the limiting block 14 is slidably connected between the air inlet 3 and the sealing strip 5, when the limiting block 14 and the sealing strip 5 conflict with each other, the air inlet 3 is opened and the sliding portion 7 closes the opening 8, and when the limiting block 14 and the connecting channel 4 conflict with each other, the sliding portion 7 closes the air inlet 3 Blocking, push the identification part 6 to move toward the side close to the connecting channel 4. Since the identification part 6 and the sliding part 7 are integrally formed, the sliding part 7 will move together. Push the identification part 6 to drive the sliding part 7 to move until it conflicts with the connecting channel 4 and then release the identification part 6. At this time, the sliding part 7 blocks the air inlet 3 to prevent the gas from flowing through. Pull the identification part 6 to move toward the side away from the connecting channel 4 and drive the sliding part 7 to move until it conflicts with the sealing strip 5. At this time, the sliding part 7 closes the opening 8 and the air inlet 3 is open. Then the user can use the inflation device to inflate the air inlet 3, so as to realize the control of the opening and closing of the inflation port;

[0026] like Figures 3 - 4 As shown, a clamping strip 9 made of a soft material is fixedly connected to the side of the identification portion 6 away from the sliding portion 7, and a clamping groove 10 is provided on the side of the sealing strip 5 away from the connecting channel 4. The clamping strip 9 and the clamping groove 10 are clamped with each other, and when the clamping strip 9 and the clamping groove 10 are clamped with each other, the limit block 14 and the connecting channel 4 conflict with each other. Since the limit block 14 and the connecting channel 4 conflict with each other when the clamping strip 9 and the clamping groove 10 are clamped with each other, the sliding portion 7 will block the air inlet 3, thereby preventing the gas from entering the air inlet 3 outside the reserved length during the inflation process;

[0027] like Figures 1 - 2 As shown, an easy-tear opening 11 is provided on the side wall of the identification strip. When the limit block 14 and the sealing strip 5 conflict with each other, the easy-tear opening 11 is located outside. After the inflation is completed, the easy-tear opening 11 can be used to remove the portion of the identification strip that exceeds the air column bag body, so that the air column bag body is more beautiful after being wrapped. In addition, an easy-tear line 12 is provided on the identification strip. The easy-tear opening 11 is located on the extension line of the easy-tear line 12, which can avoid the phenomenon of tearing crookedly when tearing, and is also more convenient to tear;

[0028] like Figure 1As shown, the surface of the air column strip 1 is provided with air vents that are in communication with its interior. A sticker 13 for closing the air vents is adhered to the outer wall of the air column strip 1. When it is necessary to remove the air column bag body to take out the item, the sticker 13 is torn off to open the air vents, and then the gas in the air column strip 1 is discharged. Then, the air column bag body can be removed from the item. At the same time, the surface of the sticker 13 facing the air column strip 1 is provided with protrusions for being inserted into the air vents, which can improve the sealing effect of the sticker 13 when it is inserted into the air vents. Moreover, patterns are formed between the stickers 13 on several air column strips 1, enhancing the overall aesthetic feeling of the air column bag body.

[0029] When the present invention is in normal use, it is as follows:

[0030] When it is necessary to wrap an item with the air column bag body, first, an air column bag body with a corresponding length is selected according to the size marked on the identification strip. The marked content on the identification strip should at least record the length of the air column bag body after the air column strip 1 is fully inflated and its deviation. Then, the air inlet 3 at this position is closed by controlling this identification strip, and the air inlets 3 before this position are successively opened by controlling the identification strips at these positions. After that, an inflation device is used to inflate the air inlet 3. Since the air inlet 3 is in communication with the air column strip 1 and a one-way valve is provided in the air column strip 1, the air column strip 1 will gradually expand. After the inflation is completed, the air column bag body is cut and the item is wrapped with the air column bag body, without the need to reserve a certain length of the air column bag body. Therefore, the waste of the reserved part of the air column bag body can be prevented.

[0031] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
