Description

Technical Field

[0001] The utility model relates to the field of bathroom products, in particular to a double pull-out water diversion body and a pull-out faucet made using the same. Background Art

[0002] The existing double pull-out faucet adjusts the ratio of hot and cold water through two left and right control valves to achieve control of hot and cold water, but its water outlet method is often relatively conventional, and the nozzle cannot be pulled and pulled at will according to usage needs; at the same time, the water inlet joint is a conventional external thread, which not only meets the requirements of the fixing nut for fixing it, but also provides a connection basis for the installation of the water inlet hose, so that both ends of the water inlet hose are brass nuts. Compared with the water inlet hose with a brass nut at one end and an external threaded joint at the other end, its cost is slightly higher (the cost of the brass nut is higher than that of the external threaded joint); the water inlet hose cannot be pre-installed at the factory, and the water inlet hose must be connected after the locking nut of the fixed faucet is installed and fixed, so the installation is more troublesome.

[0018] 4. The external screw connector of the pre-installed hose is directly screwed on to it before leaving the factory, which avoids the trouble of later installation by the user. At the same time, the external screw connector of the pre-installed hose is smaller in diameter and lighter in weight than the traditional brass nut structure. During production, it can be processed with materials with smaller diameters, effectively saving materials and reducing material costs and / or procurement costs. During fixed installation, it is only necessary to pass the locking nut through the internal screw connector and the pre-installed hose to reach the first connector, and then screw the second connector onto its external thread. Therefore, after pre-installation, there will be no interference between the two in terms of sequence.

[0019] 5. Ensure that the locking nut is installed without removing the pre-installed hose. BRIEF DESCRIPTION OF THE DRAWINGS
