It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-3, a packing tube sealing structure, including double-walled bellows 1 and head 2, double-walled bellows 1 comprises ripple outer tube 11, hollow layer 12 and smooth inner tube 13, ripple outer tube 11 both ends with smooth inner tube 13 both ends fixed connection, head 2 demountable installation in the port department of smooth inner tube 13, head 2 include cylinder 21 with install the flight 22 of cylinder 21 side, flight 22 outside is along being provided with jag 221, adjacent two jag 221 is staggered. Specifically, in this embodiment, the corrugated outer layer 1 and the smooth inner pipe 13 are sleeved to form the double-wall corrugated pipe 1, the structure is unique, the corrugated outer pipe 11 effectively improves the compressive capacity of the smooth inner pipe 13 on the annular direction, the inner wall of the smooth inner pipe 13 is smooth, the frictional resistance is small, and the electric wire can be conveniently inserted. The hollow layer 12 is arranged between the corrugated outer pipe 11 and the smooth inner pipe 13, so that the double-wall corrugated pipe 1 is light in overall weight, convenient to install, and high in low temperature resistance and insulating capability. Furthermore, an end enclosure 2 is installed at the port of the double-wall corrugated pipe 1, and the smooth inner pipe 13 is blocked by the end enclosure 2, so that the double-wall corrugated pipe is waterproof and dustproof.
