The present disclosure relates to a countertop installation assembly and a faucet.
At present, most of the faucets fixed on a counter basin or a sink are installed from below the counter basin or the sink, which is hereinafter referred to as an under-counter installation. However, the under-counter installation has the following disadvantages. 1. Installation personnel need to drill into a narrow space below the counter basin or the sink for installation, so the installation difficulty is increased. 2. The light is insufficient, and holding a light source by hand or manual operation in the dark is needed. 3. A lower space of the counter basin or the sink is also disposed with a ceramic basin, a water tank, a pipeline, and the like which obstruct the view and the operation space, so that the use or the continuous use of tools such as a wrench and the like is often limited, and the operation time is greatly prolonged. 4. When installation personnel move below the counter basin or the sink, they must perform disassembly and assembly work in a leaning and looking up posture, and this posture leads to tiring easily. Fatigue will increase significantly if the pipe layout below the counter basin or the sink prevents the normal use of the tool.
Chinese patent number 201710674815.1 discloses a countertop installation device for a faucet and a countertop installation method of the faucet. Although it is installed on a countertop, the assembly process is more complicated, there are many parts, and the operation is still very difficult.
