Description

Pipe outlet connector

This creation is related to the pipeline outlet joint, especially a water outlet joint structure which can improve the joint strength and enhance the water seepage prevention property.

In the traditional water delivery pipeline, a water outlet joint is arranged at the end of the pipeline, and a screw hole with an internal thread is arranged inside the water outlet joint for screwing to connect a water outlet control component having a relatively external thread (such as : faucet or water outlet valve), and since the water outlet control element is mostly made of metal material, the general water outlet joint is made of the same plastic (PVC) material as the water delivery pipeline, so the water outlet joint and the water outlet control element are upgraded. The adhesiveness of the joint between the two, and the demanding characteristics of the reusable combination, the current water outlet joint has a metal bushing with an internal thread embedded in the inner (water outlet), and the metal bushing is utilized. The metal water outlet control elements are in contact with each other, which can prevent the metal water outlet control component from damaging the internal structure of the plastic water outlet joint during the screwing assembly process, thereby improving the adhesion of the assembly part and improving the service life.

However, the current metal bushings are mostly embedded in the water outlet joint when the water outlet joint is formed, but since the water outlet joint is different from the metal bushing (plastic and metal) material, the joint portion of the water joint is The intimate connection cannot be produced and is limited by the overall wall thickness of the water outlet joint. Generally, the outer peripheral side of the metal bushing is not easy to increase the friction shape and structural design, so that the joint strength between the metal bushing and the water outlet joint is difficult to increase. Can not withstand the strong torque generated when the water control element is screwed.

In a more common situation, when the metal water outlet control element (such as a faucet or a water outlet valve) is slightly tightly coupled with the water outlet joint, the water outlet control element drives the metal bushing to rotate, and the metal bushing is made. The joint between the water outlet joint and the water outlet joint creates a gap; thus, the water in the water pipeline may leak out from the gap between the metal bushing and the water outlet joint, and moreover, It may cause damage to the metal bushing and the water outlet joint, resulting in a serious lack of use.
