Description

A kind of column-type water tap

Technical field

The present invention relates to a kind of column-type water tap.

Background technique

In the market the column-type water tap of Chu Xianing bottom and shell generally be integral type structure, electrolytic solution is easy to accumulate each corner of portion in the enclosure when therefore shell being electroplated, be difficult to this part electrolytic solution is cleaned out, and because the obstruct of bottom is arranged, the shell of this column-type water tap adopts the difficulty of the technology injection moulding of loosing core very big, and the die cost that relates to is higher relatively.

Summary of the invention

Technical problem to be solved by this invention provides a kind of column-type water tap, and the bottom of this column-type water tap can freely mount and dismount on leading shell and be fixed on fastening piece on the wash-basin as water tap.

For this reason, column-type water tap provided by the invention comprises leading main casing, have bottom on the tap main casing, shell, valve seat and outlet pipe, bottom and shell split are provided with, bottom is equipped with retainer ring, retainer ring is threadedly connected to the bottom of shell, bottom is in the shell and is supported on the retainer ring, also be provided with water supply connector on the bottom, the valve seat bottom is connected with the intake pipe with the conducting of valve seat water inlet, and intake pipe connects water supply connector, and the lower end of retainer ring has extension part, this extension part has outside thread, and described extension part also disposes the retaining ring that has internal thread that can be threaded on it.

Because the bottom of column-type water tap provided by the invention is equipped with retainer ring, retainer ring and shell are for being threaded, retainer ring can be supported in bottom in the shell, bottom and shell are split type structure, bottom can be installed or dismantle as required at any time, the shell that bottom is not installed at first can be electroplated when therefore needing to electroplate, and cleans out electrolytic solution from outer casing bottom then, install bottom at last, this structure makes electrolytic solution can not accumulate polluted water tap in the enclosure.And this structure can directly be loosed core the shell of water tap by the bottom when injection moulding, can reduce the manufacture difficulty and the cost of mould, but each parts in the shell also split are made separately and assembling, make each interior parts of shell can act on universal component and be applicable to multiple water tap, and need not the design iterations manufacturing.And, the of paramount importance retainer ring that is column-type water tap of the present invention provides has downward extension part, this extension part can insert the through hole that the water pipe on the wash-basin passes, then retaining ring is threaded on it, this moment, water tap can directly not be fixed on the wash-basin by other fixed blocks, therefore the setting that can save fixed mechanism makes the structure of water tap simpler, and easier for installation on wash-basin.
