Benefits of technology

"The invention is a telescopic coupling tube for a vacuum cleaner that improves upon the conventional extension tube. It allows for easier and more convenient use of the vacuum cleaner. The mounting tube and telescopic tube are attached together, and a locking assembly is used for easy adjustment of the assembly length. This allows for easy use without affecting the original storage effect."

Problems solved by technology

It's not possible for further extension if required.
In other words, the user has no other way for extension even when the length is not sufficient.

Abstract

A telescopic coupling tube for a vacuum cleaner includes a mounting tube, a connecting sleeve, a sealing sleeve, a telescopic tube, a locking assembly, and a positioning cap. The connecting sleeve is provided for the insertion of the telescopic tube. A guide slot and toothed engaging holes are formed in the telescopic tube. Based upon the interaction of the above-mentioned components, an easy adjustment of the assembly length is achieved.

Description

BACKGROUND OF THE INVENTION[0001]1. Fields of the Invention[0002]The invention relates to a telescopic coupling tube for a vacuum cleaner, and more particularly, to a structure that ensures an easy adjustment of the assembly length, thereby meeting the use requirements.[0003]2. Description of the Related Art[0004]The conventional vacuum cleaner (not shown) normally includes a plurality of extension tubes and different kinds of suction heads that are engaged into the rear end surface of the body of the vacuum cleaner. In this way, they can be employed in accordance with user requirements. The plug-type connection belongs to the prior art so that no further descriptions thereto are given hereinafter. The invention relates to a dust absorption head for a vacuum cleaner.[0005]As well-known in the art, the conventional extension coupling tube for a vacuum cleaner has a fixed length. It's not possible for further extension if required. In other words, the user has no other way for extensi...
