20140319832 | THREAD STRUCTURE OF AN AERATOR FOR WATER FAUCET OUTLET - The present invention provides a thread structure of an aerator of a water faucet outlet, which is to solve the problem of the different metric and imperial measurement of the thread of an existing water faucet outlet would result in the aerator cannot be universally used for both measurements; based on the pitch, the major diameter and the ditch diameter of the metric and imperial thread of water faucet outlet and the variation tolerance, the present invention calculates the universal measurement of corresponding pitch, major diameter and pitch diameter and the variation tolerance, such that the aerator can be engaged and locked in a metric water faucet outlet and also can be engaged and locked in an imperial water faucet outlet, thereby achieving a universal utilization effect. | 10-30-2014 |
