Thread structure of aerator of faucet water outlet

Abstract

The present invention provides a thread structure of an aerator of a faucet water outlet, which is to solve the problem of the different metric and imperial measurement of the thread of an existed faucet water outlet would result in the aerator cannot be universally used for both measurements; based on the ditch, the major diameter and the ditch diameter of the metric and imperial thread of faucet water outlet and the variation tolerance, the present invention calculates the universal measurement of corresponding ditch, major diameter and ditch diameter and the variation tolerance, such that the aerator can he engaged and locked in a metric faucet water outlet and also can be engaged and locked in an imperial faucet water outlet, thereby achieving a universal utilization effect.

What is claimed is: 
     
         1 . A thread structure of aerator of faucet water outlet, wherein the design of an external thread structure of aerator enables the aerator to be engaged with both metric and imperial dimensioned internal thread of faucet water outlet,
 the said external thread structure of the aerator comprises:   0.960 mm pitch, wherein the angle is 60 DEG, wherein the max major diameter is 23.760 mm, wherein the min major diameter is 23.619 mm, wherein the max pitch diameter is 23.244, and wherein the min pitch diameter is 23.084 mm.   
     
     
         2 . A thread structure of aerator of faucet water outlet, wherein the design of an internal thread structure of aerator enables the aerator to be engaged with both metric and imperial dimensioned external thread of faucet water outlet,
 the said internal thread structure of the aerator comprises:   0.960 mm pitch, wherein the angle is 60 DEG, wherein the max minor diameter is 23.057 mm, wherein the min minor diameter is 22.889 mm, wherein the max pitch diameter is 23.442, and wherein the min pitch diameter is 23.188 mm.   
     
     
         3 . A thread structure of aerator of faucet water outlet, wherein the design of an internal and external thread structure of aerator enables the aerator to be engaged with both of a metric and an imperial dimensioned internal and external thread of faucet water outlet,
 the said internal thread structure of the aerator comprises:   0.960 mm pitch, wherein the angle is 60 DEG, wherein the max minor diameter is 23.057 mm, wherein the min minor diameter is 22.889 mm, wherein the max pitch diameter is 23.442, and wherein the min pitch diameter is 23. 188 mm; and   the said external thread structure of the aerator comprises:   0.960 mm pitch, wherein the angle is 60 DEG, wherein the max major diameter is 23.760 mm, wherein the min major diameter is 23.619 mm, wherein the max pitch diameter is 23.244, and wherein the min pitch diameter is 23.084 mm.
