Description

Wall-in type concealed telescopic water outlet joint and mounting method

Technical Field

The invention belongs to the technical field of water heating, relates to a water outlet joint, and particularly relates to a wall-in type concealed telescopic water outlet joint and an installation method.

Background

The wall-embedded water faucet is characterized in that a water supply pipe is embedded in a wall, water is directly guided into a washbasin or a water tank positioned outside the wall through a wall-embedded water outlet nozzle, the water faucet and the water tank are independent, the water tank does not need to be installed with the water faucet, and direct contact with the water tank is avoided, so that the wall-embedded water faucet is convenient to install, has more design spaces in modeling and is popular. For example, the Chinese patent document discloses an embedded water tap [201811187368.8], which comprises an embedded box embedded in a wall and a panel clamped on the surface of the wall, wherein the panel is detachably connected with the embedded box; the panel is provided with two openings, and the two openings are respectively provided with a rotating handle and a water outlet nozzle; the embedded box is internally provided with a joint, a valve core switch and a right-angle joint which are sequentially connected, one end of the joint, which is positioned outside the embedded box, is used for connecting a tap water pipeline, the valve core switch is connected with the rotating handle and controlled by the rotating handle, and the right-angle joint is connected with the water outlet nozzle.

The technical problem that the installation is difficult exists in above-mentioned scheme, and its reason lies in that the main part of burying the wall body is fixed mounting in the mounting groove on the wall body, because the length of main part and tap connecting portion can not be adjusted, the degree of depth of main part in the mounting groove needs strict the accuse. If the depth of the main body in the mounting groove is too deep, the water faucet cannot be mounted to the main body; if the depth of the main body in the mounting groove is too shallow, the inner end of the faucet after mounting can not contact with the panel, and the panel can not be clamped and positioned. Above is the installation difficult problem that faces when new dress, obviously, still can have when renovating again or renovating, because newly-increased wall fitment layer and/or the original fitment layer of eradicating the wall lead to original wall thickness to change, is difficult to guarantee that original wall thickness does not change this moment obviously almost, leads to tap can't be installed to the main part or install the tap after accomplishing the inner can not contact with the panel. If the whole main body is taken out again and then installed, the time and the labor are obviously wasted, and the installation problem is also faced when the main body is newly installed.
