Lavatory faucet

Abstract

A lavatory faucet is fixed on a basin and contains: a body and a fixing device. The body includes a housing and a supply pipe assembly; the fixing device includes a mounting seat, two screw rods, and two clamping blocks; the basin includes a central orifice, a left orifice, and a right orifice. The mounting seat includes an upper fitting sleeve, two extending wings for abutting against a top face of the basin, and two support feet. The upper fitting sleeve has a channel defined therein relative to the central orifice, each extending wing has a through hole to insert each support foot, and each support foot has a first stopping fence. Each screw rod extends out of the through hole and is rotated above the mounting seat, each clamping block is screwed with each screw rod and is limited by the first stopping fence as rotating each screw rod.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a lavatory faucet fixed on a basin with a central orifice, a left orifice, and a right orifice.BACKGROUND OF THE INVENTION[0002]A conventional facet is installed in a narrow space below a basin which is located in a kitchen or a bathroom.[0003]A positioning structure for a faucet disclosed in U.S. Pat. No. 8,763,175 B2 is fixed on the basin from an upper end of the basin. The faucet contains a body and a fixing device for installing the faucet on the basin from the upper end of the basin. The fixing device includes a mounting seat, two screw rods, and two clamping blocks. The mounting seat is inserted into an orifice on the basin and is employed to fix the body and to insert a supply pipe assembly. The supply pipe assembly has a first inlet pipe for flowing cold water, a second inlet pipe for flowing hot water and an inflow pipe for flowing a mixed water of the cold water and the cold water. The two screw rods are rotated ...

AI Technical Summary

Benefits of technology

[0013]2. The diameter of the channel is larger than that of the central orifice, and the two support feet are retained with the left orifice and the right orifice by ways of the two screw rods and two clamping blocks so that the mounting seat is fixed on the basin, and only the supply pipe assembly is inserted through the central orifice easily.

[0014]3. The two screw rods are rotated, and the two clamping blocks screwed with the two screw rods are rotated to accommodate in the two support feet or below two stop columns so that the fixing device is mounted on the basin easily, thereafter the two screw rods are rotated above the mounting seat of the basin so that the two clamping blocks engage with the bottom face of the basin tightly, thus fixing the fixing device. Accordingly, the body is fitted on the upper fitting sleeve of the fixing device, the supply pipe assembly is inserted through the central orifice of the basin from the channel of the upper fitting sleeve, thus fixing the lavatory faucet easily and quickly.

Problems solved by technology

Therefore, when the basin has three orifices, a diameter of which is less than 32 mm, the mounting seat cannot be fixed in the three orifices.

Even through a size of the mounting seat is reduced, a channel in the mounting seat is decreased accordingly, so the supply pipe assembly cannot be mounted in the channel.
