Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a shower pipe.

Description of the Prior Art

The conventional shower device is provided with a flower higher than the head of a user, which can directly wash the shoulder and neck of the body. However, it is necessary to adjust the flower according to various heights of users.

The conventional shower device includes a telescopic tube, a bushing and a threaded rod. The telescopic tube includes an upper tube and a lower tube, and the bushing is disposed on the upper tube and is located between the upper tube and the lower tube. The threaded rod is inserted within and locks the lower tube to urge and radially deformed the bushing to tighten the upper tube to positioningly secure the upper and lower tubes. However, the conventional telescopic tube is positioned only by the threaded rod in single-point positioning. It has the disadvantage of poor positioning effect such that the threaded rod and the bushing are often unable to resist the impact of the strong water flow, resulting in the upper tube being easy to loosen relative to the lower tube. As a result, it is difficult to stabilize and fix the flower at a specific height required for a user.

The present invention is, therefore, arisen to obviate or at least mitigate the above-mentioned disadvantages.
