Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained by combining the specific embodiments.

Referring to fig. 1, 2, 3, 4 and 5, the present invention provides a technical solution of a plastic faucet body assembly: the structure of the novel water-saving valve comprises a plastic body 1, a lower cover 2, a water outlet pipe 3, a transverse channel 4, a valve core position 5, a water inlet pipe 6, a metal pin 7, a water outlet 8, a notch 9, a positioning rib 10, a welding rib 11, a flash collector 12 and a weld penetration 13, wherein the plastic body 1 consists of the transverse channel 4 and the valve core position 5, two ends of the connecting channel are communicated with the channel, an inner cavity of the connecting channel is communicated with the channel, an outer thread is arranged at an upper opening of the valve core position 5, the water inlet pipe 6 is positioned at the lower end of the valve core position 5, the metal pin 7 is wrapped outside the water inlet pipe 6, the water outlet 8 connected with a water outlet nozzle 3 is arranged on the transverse channel 4, the plastic body 1 and the lower cover 2 are welded through a plane profile surface, the notch 9 convenient for installing the valve core is arranged at the upper part of the valve core position 5, the outer edge of the valve core position 5 is provided with the outer thread, the water outlet 8 is provided with a quick installation rotating buckle, the positioning rib 10 is arranged at the outer edge of the lower cover 2, the bottom of the lower cover 2 is provided with the welding rib 11, the lower cover 2 is welded with the plastic body 1 through vibration friction welding rib 11, the welding rib with the plastic body 12 at the outer side of the lower cover 2.
