Joint structure configured for pull-out tube, pull-out tube structure, and faucet
View Patent ↗A joint structure configured for a pull-out tube, a pull-out tube structure, and a faucet. The joint structure includes a joint body, two connecting heads respectively disposed on two ends of the joint body, a magnetic component, and an embedded member. The two connecting heads are configured to be connected to the pull-out tube. The magnetic component is sleeved on an outside of the joint body by a first insert molding process, and an outside of the magnetic component is partially encased in the joint body. The magnetic component is partially exposed outside the joint body to form an exposed space, and the embedded member is molded on the exposed space by a second insert molding process. The joint body and the embedded member are combined to encase the magnetic component.
