Abstract

A telescopic waterproof tube structure includes at least two connection tubes nested with each other, and a locking structure for locking two adjacent connection tubes that are made of an inner tube sleeved inside an outer tube. The locking structure includes an inner reducing sleeve fixed on an end of the outer tube, an outer reducing sleeve adjustably connected to the inner reducing sleeve, and a locking assembly provided between the inner reducing sleeve and the end to be connected of the inner tube. The locking assembly moves axially towards the inner reducing sleeve under the action of the outer reducing sleeve to clamp the inner tube on said inner reducing sleeve. A first sealing structure is provided between the inner and outer reducing sleeves. An activity seal slot surrounding the inner tube forms between the outer reducing sleeve and the locking assembly and accommodates a second sealing structure therein.
