Description

Technical Field

[0001] The utility model relates to a manufacturing technology of parts for sanitary ware. Background Art

[0002] With the continuous improvement and progress of technology, the number of faucet products that can be installed on countertops or basins is increasing. This solves the problem of difficulty in installing and replacing original faucets due to the small space behind the basin, and makes the installation and replacement of faucets more convenient.

[0003] Due to the specification limitations of the faucet mounting holes on the countertop and basin, after the top-mounted faucet valve body fixings are installed in the mounting holes of the basin or countertop, the fixing screws of the upper and lower fixings occupy part of the inner diameter of the basin or countertop mounting hole, making the space of the inner diameter of the mounting hole even smaller. The joint connecting the faucet hose and the water supply valve is large and cannot pass through the narrow gap of the countertop or basin mounting hole from above, thus failing to realize the practical concept of top installation.

[0004] In order to solve the problem of inconvenient operation when installing and replacing faucets, and to make the installation and replacement of top-mounted faucets more convenient and quick, the structure and connection method of the hose connector of the faucet need to be improved.
