Description

Technical Field

[0001] This utility model relates to the field of faucet technology, specifically to a quick-installation structure for a pull-out faucet and a pull-out faucet itself. Background Technology

[0002] Pull-out faucets can extend and retract naturally, meeting various water usage needs and are widely used in kitchens and bathrooms. During assembly, the valve core needs to be secured within the housing using a valve core seat. Figure 1 As shown, this is the existing installation structure of a pull-out faucet. During installation, the valve seat must first be inserted from the side of the faucet body, then the valve core is installed and the handle is connected. Finally, the inlet and outlet water pipes are installed from the bottom and locked with a pressure cap. This structure lacks a positioning feature for the valve seat, and aligning the inlet and outlet water pipes when installing them from the bottom is inconvenient, increasing the difficulty of installation.

[0003] In view of this, the applicant hereby submits this application after studying the existing technology. Utility Model Content
