Water Discharge Pipe and Drain Head Assembly Structure

Abstract

A water discharge pipe and drain head assembly structure that, by means of a matched drain head inner diameter bore, seal ring shape, and clamp ring, enables the utilization of a simple stomp operated, additionally fabricated, foot-driven component which is sleeved into the inner diameter bore of the drain head to shove down the clamp ring a predetermined distance and thereby compress and deform the seal ring such that a tightly sealed contact is established against a water discharge pipe inserted through them. The arrangement effectively affords optimal watertight anti-seepage efficacy between the water discharge pipe and the drain head, fully solving the numerous problems and shortcomings of the conventional threaded-type mounting ring.

Description

BACKGROUND OF THE INVENTION[0001]1) Field of the Invention[0002]The invention relates to a water discharge pipe and drain head assembly structure that addresses water discharge pipe and drain head conjoinment and fitting design, the structural design of its drain head enabling, by means of a simple and easy foot-driven operation, the rapid attainment of a watertight anti-seepage state between the drain head and the water discharge pipe that thoroughly solves the numerous problems and shortcomings of the conventional threaded-type mounting ring.[0003]2) Description of the Prior Art[0004]Conventional bathroom accessory-type, drain head and water discharge pipe assemblies, referring to FIG. 1 and FIG. 2, typically consist of a drain head 10 having died onto its exterior aspect external threads 101, accompanied as well by a gasket 11, a washer 12, and a mounting ring 13, enabling the installation of the drain head 10 into a drainage hole at a predetermined position in the floor; along t...

Benefits of technology

[0009]In view of the existent derivative problems and shortcoming of the prior art structure, the inventor of the invention herein conducted research to effect improvement based on years of engagement in the relevant industries that culminated in the development of the improved structure of the present invention, the primary objective of which is to provide a convenient assembly structure wherein an easy foot-driven operation rapidly completes the coupling of the drain head to the water discharge pipe to effectively achieve watertight anti-seepage efficacy between them.

[0010]Another objective of the invention herein consists of, via the structure of its assembly design, enabling not only easier assembly, but also the effective simplification of the overall structure as well as the significant reduction of its assembly cost.

[0012]To achieve said objectives, the structural design of the invention herein, utilizes a seal ring having an inward fold along the center section of its outer diameter along with a drain head-inner diameter bore plan, and an additionally fabricated foot-driven component, the latter enabling by means of a simple stomping action, the trampling down of the additionally fabricated foot-driven component sleeved into the drain head inner diameter bore to shove in a clamp ring a predetermined distance and thereby compress and deform the seal ring such that a tightly sealed contact is established against a water discharge pipe inserted through them, effectively affording a watertight anti-seepage relationship between the water discharge pipe and the drain head, the arrangement constituting a convenient, practical, and unique design.

Problems solved by technology

(1) Due to the physical peculiarity of the mounting ring, a specially fabricated tool bar must be included to facilitate its fastening and, furthermore, since the mounting ring requires turning down to a specific depth before the water stopping ring reaches ideal compressive effectiveness, resulting imperceptibly in a very troublesome and inconvenient procedure, and furthermore, fastening consumes much time, the design of the mounting ring is difficult to describe as ideal.

(2) Due to the fastened installation of the mounting ring, internal threads must be tapped along the drain head inner diameter bore and, at the same time, external threads died along its outer diameter, resulting in overall assembly and machining operations that are quite complicated, affecting imperceptibly its total production cost, which does not conform with manufacturing economic benefits.

In other words, the prior art drain head and water discharge pipe assembly structure, since its structural design is not fully perfected, results in higher machining costs, troublesome assembly that is time consuming, such that its design can hardly be described as ideal and which certainly awaits the development of methods providing solution and improvement.
