Description

a pipe faucet

technical field

The invention relates to the technical field of faucets, in particular to a pipe-penetrating faucet.

Background technique

In order to reduce the product cost, the faucet body needs to be made of a zinc alloy part, and the current zinc alloy body is usually in the form of two-piece or zinc alloy recasting. The two-piece faucet will have a clear demarcation line in appearance, which will affect the appearance of the product. Zinc alloy recasting can ensure the integrity of the product appearance.

Patent No. CN208381425U discloses a faucet, including a faucet body and a water outlet structure, the faucet body has a cavity, the water outlet structure includes an inner tube and a bubbler, the inner tube is embedded in the cavity of the faucet body, and bubbles The faucet is threadedly connected to the water outlet of the cavity; one end of the water outlet of the inner pipe is detachably and fixedly connected to the shell of the faucet body, so that the position of the inner pipe of the faucet relative to the water outlet of the faucet body can be fixed. The operation of the bubbler will not cause the loosening of the inner pipe, which avoids the water leakage problem of the faucet caused thereby. Specifically, the inner pipe is detachably connected to the outer shell of the faucet body through the first screw connection. Through the threaded connection relationship formed by the first threaded connection piece, the first through hole and the threaded hole, the inner pipe forms a detachable fixed connection relationship with the shell of the faucet body at one end of the water outlet. In addition, the faucet further includes a valve body assembly, the valve body assembly includes a valve body base, the valve body base is provided with a water outlet, the water outlet is connected to the water inlet of the inner pipe, and one end of the water inlet of the inner pipe is provided with a second threaded connection piece, The second threaded connector is provided with an external thread, and the inner wall of the water outlet hole of the valve body base is provided with an internal thread matched with the second threaded connector. Through the above structural design, the position of the inner pipe relative to the faucet body is fixed. The operation of dismantling and cleaning the bubbler will not cause the loosening of the inner pipe, which avoids the water leakage problem of the faucet caused thereby.

The shortcomings of the above patent solutions are: (1) The threaded connection relationship formed by the first threaded connection piece, the first through hole and the threaded hole makes the inner pipe at one end of the water outlet and the shell of the faucet body form a detachable fixed connection relationship. This connection relationship structure is more complicated. (2) One end of the water inlet of the inner pipe and the outlet hole of the valve body base are threadedly connected. Since the inner pipe and the valve body base are both installed in the faucet body, the threaded connection point of these two parts is located in the faucet body. In the cavity, it cannot be installed and entered after the faucet body is combined, so the faucet body can only be designed as a two-piece split structure. The dividing line affects the beauty of the product, and the structure is not firm.
