Quick-Connect Structure for Quick Connection of Piping Elements

Abstract

The present invention provides a new-model quick-connect device for piping elements. It solves the problem of difficult disassembly, poor sealing and easy occurrence of leakage in quick-connect structures for piping elements. In one embodiment, the new-model quick-connect device for piping elements of the present invention comprises a main body having an interior surface defining a connecting hole, and the main body can connect with a connecting tube inserted into the connecting hole. An annular groove is provided in the inner surface of the main body defining the connecting hole, and a sealing washer that can form an air-tight or fluid-tight seal with the inserted connecting tube is embedded in the annular groove. Located radially outwardly of the sealing washer is a clamping ring that can connect with the connecting tube. The connecting ring has a plurality of jack catches that incline toward the inside of the connecting hole. When the tube or piping is inserted, the clamping ring grips the tubular member, providing increased opposing force to prevent disconnection. Radially outwardly of the clamping ring, there is an annular socket which can push away the jack catches when the clamping washer is pushed against the inner surface defining the connecting hole. The present invention is reliable to use, versatile and convenient, has a high sealing performance and can be used for temporary or permanent connections.
