Abstract
A connector is provided for piping which may prevent a cap nut part from being automatically loosened or locked due to external force, such as an external vibration, a bump, or a shock, that i not deliberately applied, before a connector product is used, and in addition, may prevent an O-ring from being separated from the inside of the connector due to pressing caused by erroneous assembly in a pipe fastening process. To this end, the connector for piping comprises: a body part of a pipe body; the cap nut part; a collet part; and an anti-loosening part which prevents the cap nut part from being loosened or locked due to external force that is not deliberately applied.
Claims10
A connector for piping comprising:
- a body having a tubular shape and having an inlet and an outlet defined therein;
- a cap nut having one end screwed to an outer circumferential surface of the inlet or the outlet of the body;
- a collet fitted into an inner circumferential surface of the cap nut through an opening of another end of the cap nut, wherein the collet presses and fixes an outer circumferential surface of a connection target pipe inserted into an inner receiving hole of the collect collet when the cap nut is screwed to the body;
- and
- an anti-loosening mechanism including:
- stopped protrusions formed on an inner circumferential surface of one end of the cap nut;
- a stopper protrusion formed on an outer circumferential surface of the body, wherein the stopped protrusion is engaged with the stopper protrusion to prevent the cap nut screwed, at a predetermined position, to the body from being loosened therefrom under an external force;
- and
- stopper ribs formed on the outer circumferential surface of the body and spaced from each other by a predetermined angular spacing, wherein the stopped protrusion is engaged with the stopper ribs to prevent the cap nut coupled to the body from being loosened or locked under an external force,
- wherein the body includes an anti-loosening ring which is provided as a separate structure and received in a groove of the body, and the stopper protrusion and the stopper ribs are formed on an outer circumferential surface of the anti-loosening ring and are integrally formed with the anti-loosening ring such that the stopper protrusion and the stopper ribs are received in the groove of the body.
