Liquid-tank connector

摘要

Provided are a joining portion in which a male threaded portion threaded to a container-side female threaded portion is formed; a connector main unit disposed at an inner side of the joining portion, sharing a center axis therewith, and is connected so as to be rotatable relative thereto; and a siphon tube attached to the connector main unit so as to extend toward the bottom portion of the container and has a tip curved in a substantially horizontal direction, wherein the joining portion is screwed in independently of the connector main unit when attaching the connector by using a securing jig that, by being inserted from above the connector main unit, causes depressed/protruding portions to be engaged, thus preventing relative rotation to each other, and by using a tightening jig that tightens the male threaded portion by being engaged at the upper surface of the joining portion.

1. A liquid-tank connector that is installed at a vent plug portion of a container storing liquid and that draws out the liquid from the container, the liquid-tank connector comprising:
a joining portion in which an outer threaded portion that is threaded to a container-side inner threaded portion formed in the vent plug portion is formed; a main unit that is disposed at an inner side of the joining portion, sharing a center axis therewith, and that is connected so as to be rotatable relative thereto; a liquid draw-out tube that is attached to the main unit so as to extend toward a bottom portion of the container and that has a tip curved in a substantially horizontal direction, wherein the joining portion is screwed in independently of the main unit when attaching the connector by using a securing jig that, by being attached from above to the main unit, causes depressed/protruding portions provided between contact surfaces to be engaged, thus preventing relative rotation to each other, and by using a tightening jig that tightens the outer threaded portion by being engaged at an upper surface of the joining portion; wherein the securing jig is inserted from above into a circular hollow portion formed at the upper surface of the main unit, thus engaging the depressed/protruding portions between the contact surfaces; and wherein the circular hollow portion is a key ring portion that is attached at a top portion of the main unit, forming a single piece therewith.
