The connecting member 14 is provided with a flow guiding hole (not shown), one end of the flow guiding hole is communicated with the air cavity 123 through the second pipe portion 132, and the other end of the flow guiding hole is disposed on the end surface of the connecting member 14 facing the first housing 21. The inserting portion 211 is provided with a first pipe portion 131 which is convexly arranged, when the inserting portion 211 is inserted into the groove portion 221, the first pipe portion 131 is inserted into the other end of the flow guide hole, and therefore the air cavity 123 is communicated with the inflatable column 111. In order to ensure the sealing property after the first pipe portion 131 is connected to the diversion hole, the second pipe portion 132 in this embodiment is a rigid connection pipe, and the connection member 14 is a rubber member.
According to the packing box 1 of the present invention, an article to be protected is placed in the lining 10 of the packing box, and the article is placed in the receiving cavity surrounded by the plurality of inflatable pillars 111, the article is placed on the cover 122, and the air cavity 123 surrounded by the cover 122 and the box body 121 is pressed, and since the air cavity 123 is communicated with the inflatable pillars 111 through the first pipeline 13, the air cavity 123 has a certain pressure, and is used for supporting the article, and simultaneously, the inflatable pillars 111 are in an inflated state, and are used for protecting the radial direction of the article. When the article is bumped in the transportation process, the air cavity 123 expands along with the rising motion of the article, and the air cavity 123 shrinks along with the falling motion of the article, so that the falling process of the article is buffered, and the bottom of the article is prevented from being impacted. The pressure of the expanded air cavity 123 is reduced, so that the inflatable column 111 communicated with the air cavity 123 is reduced and deformed, the pressure of the reduced air cavity 123 is increased, so that the inflatable column 111 communicated with the air cavity 123 is in an inflated state again, when the pressure in the inflatable column 111 is greater than the opening pressure of the one-way valve 114, the one-way valve 114 is opened and discharges redundant air in the inflatable column 111, so that the explosion leakage of the inflatable column 111 caused by excessive pressure is prevented, and the protection effect on articles is ensured; when article received radial impact in the transportation, radial impact can be alleviated effectively to gas column 111, the gas in the gas column 111 can flow to air cavity 123 or discharge through the gas vent under radial impact's effect simultaneously, thereby prevent to cause gas column 111's blasting leakage because pressure is too big, after radial impact disappears, article on the lid 122 extrude air cavity 123 once more, make the pressure increase of air cavity 123 and make gas column 111 fill again, thereby can carry out a lot of to gas column 111 and aerify and exhaust, prevent gas column 111 blasting leakage, make gas column 111 remain the guard action all the time, and then guarantee the guard effect to article.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
