Description

Technical Field

[0001] The utility model relates to the technical field of buffer structures, in particular to a buffer structure for fragile product packaging. Background Art

[0002] The buffer structure is a device used to protect fragile items placed inside a packaging box. When the buffer structure is used, the fragile items are clamped by the first connecting frame and the second connecting frame, and then air is inflated into the first connecting frame and the second connecting frame through the air inlet pipe, so that the two inflatable films are squeezed on both sides of the fragile items. In this way, the fragile items can be wrapped by the inflatable films, which can protect the fragile items.

[0003] The inventors have found in their daily work that the buffer structure still has at least the following problems: when using the buffer structure, air is inflated into the interior of the first connecting frame or the second connecting frame through the connecting tube, so that the two inflatable films are squeezed on both sides of the fragile object, so that the fragile object can be wrapped by the inflatable film. However, in actual use, the connecting tube is plugged with a sealing plug to avoid air leakage, because the sealing plug will be squeezed by the gas on one side of the inflatable film away from the connecting tube, which may cause air leakage, which may affect the buffering of the fragile object.
