Abstract

The invention discloses an anti-loosening and adhesion-free diaphragm faucet. The anti-loosening and adhesion-free diaphragm faucet comprises a valve body, a rubber diaphragm, a pressure rubber ring,a gland, a lifting screw rod and a screw cap, wherein the lower part of the lifting screw rod is in the shape of a hollow cylinder, an external trapezoidal thread is formed on the outer wall of the cylinder and adaptive to an internal trapezoidal thread of the pressure rubber ring, and the upper part of the lifting screw rod is a non-cylinder; the tail end of the external trapezoidal thread of thelifting screw rod is thread-free, so that the lifting screw rod is capable of freely moving up and down, and capable of being located and locked independently while ascending to a set position; an internal thread is formed on the inner wall of the gland and adaptive to an external thread on the valve body; a concave hole adaptive to the non-cylinder on the upper part of the lifting screw rod is formed in the screw cap; and the lifting screw rod is arranged in the pressure rubber ring and adaptive to the pressure rubber ring, the pressure rubber ring is assembled in a manner of being matched with the valve body and tightly presses the rubber diaphragm, the gland is connected with the valve body through a thread and fixes the pressure rubber ring, and the screw cap is arranged outside the gland in a sleeving manner and connected with the lifting screw rod. The faucet is simple in structure, reasonable in design, and convenient to use, and further has the characteristics of being anti-loosening and adhesion-free.
