Valve body and tap connection structure of kitchen tap

Abstract

The invention discloses a connecting structure for a valve body of a kitchen faucet and a faucet body, which comprises a valve body connecting position and a faucet body connecting position; and the faucet body connecting position is a three-step segment structure decreased step by step, wherein the first step segment and the third step segment are provided with grooves, each groove is provided with an O-shaped sealing ring, the second step segment is provided with a bearing in interference fit, simultaneously the felly of the bearing is in interference fit with a connecting hole of the valve body connecting position. The invention overcomes the disadvantages of the connecting structure for the valve body of the present kitchen faucet and the faucet body, and the connecting structure has the characteristics of convenient installation, stable connection, free rotation and long service life.

Description

technical field [0001] The invention relates to a kitchen faucet, in particular to a connection structure between a valve body and a faucet body of a kitchen faucet. Background technique [0002] Such as figure 1 with 2 As shown, it is the connection structure between the valve body and the faucet body of the existing kitchen faucet. The structure is that the connection part of the faucet body 1' is a body of equal diameter, and four annular flanges 11', 12' are arranged on the body of equal diameter. . The ring 3' is used for sealing, and an opening buckle 4' is set in the middle groove 22' for connection. The buckle 4' is generally made of plastic material, and the buckle 4' is connected with the valve body 5' after installation The connection hole 51' of the part is clearance fit, and the connection and positioning of the faucet body 1' and the valve body 5' is mainly realized by the positioning pin 52' provided on the valve body being supported on the buckle 4'. This...

AI Technical Summary

Problems solved by technology

This connection structure can basically realize the function of the faucet body 1' rotating around the valve body 5', but the installation is cumbersome, requiring special tools, and the stability of the connection is also relatively poor, because the positioning of the positioning pin 52' is only at the A point on one side of the buckle 4' makes the connection between the faucet body 1' and the valve body 5' not tight, and the faucet body 1' will sway to a certain extent during the rotation process, which seriously affects the sealing of the connection between the two

Simultaneously because the head of locating pin 52 ′ is directly offset against plastic buckle 4 ′, this aspect will bring relatively large frictional force to buckle 4 ′, making the rotation of faucet body 1 ′ jerky, producing abnormal noise, and making the The buckle 4' wears more and more, which seriously affects the service life of the buckle 4', so it needs to be replaced from time to time

In addition, the tail of the positioning pin 52' is exposed on the outer surface of the valve body 5', which will also destroy the overall appearance of the valve body 5' surface.
