Claims

[Claims for Utility Model Registration] (1) A plug is rotatably housed in the gas tank main body, and by rotating the plug via the handle, the gas inflow passage and the gas outflow passage provided in the gas tank main body can be opened. A gas tank for communicating and blocking communication, characterized by comprising the following (a) a connecting member, (b) an erroneous operation prevention cover, (c) a stopper protrusion, and (d) a stopper groove. (b) The end has a threaded hole leading to the gas outlet passage of the gas kettle body, the outer peripheral surface of the end is used as a tool hook for a tool such as a spanner, and the gas kock body rotates in a sealed state. A freely supported connecting member. (b) It has a cylindrical shape, into which the supporting part of the gasket main body and the connecting member for the connecting member are inserted, is movable in the axial direction, and is biased by an elastic member in a direction approaching the connecting member. The cover covers the tool hook part of the connecting member when it is located on the connecting member side, and exposes the tool hook part when it is located on the gas tank main body side. (c) A stopper protrusion that is provided on the outer circumferential surface of the support portion of the gas cock body for the connection member, and that is provided on the movement locus of the rear end of the erroneous operation prevention cover and protrudes radially outward. (d) Provided on the inner peripheral surface of the erroneous operation prevention cover, extends axially forward from the rear end surface of the erroneous operation prevention cover, and engages with the stopper protrusion to move the erroneous operation prevention cover in the axial direction without being able to rotate. A first engagement groove that enables rotation of the first engagement groove, and a misoperation prevention cover that connects to the tip of the first engagement groove and extends in the circumferential direction of the misoperation prevention cover, engages with the stopper protrusion, and moves toward the gas cylinder body. and a second engagement groove that makes it impossible to move in the axial direction. (2) A gas tank in which a stopper is rotatably housed in the main body of the gas tank, and by rotating the stopper via a handle, a gas inflow passage and a gas outflow passage provided in the main body of the gas tank are communicated with and shut off, The following (A) connection member, (B) erroneous operation prevention cover, (C) erroneous operation prevention cover rotation prevention mechanism, and (D)
A gas tank characterized by comprising a connection member rotation prevention mechanism. (A) The end has a screw hole leading to the gas outflow passage of the gas kettle body, the outer peripheral surface of the end is used as a tool hook for a tool such as a spanner, and the gas kock body rotates in a sealed state. A freely supported connecting member. (B) It has a cylindrical shape, into which the supporting part of the gasket main body and the connecting member for the connecting member are inserted, is movable in the axial direction, and is biased by an elastic member in a direction approaching the connecting member. The cover covers the tool hook part of the connecting member when it is located on the connecting member side, and exposes the tool hook part when it is located on the gas tank main body side. (C) An engaging protrusion that is provided on the outer circumferential surface of the support part of the gas cock body for the connection member and that is provided on the movement locus of the rear end of the erroneous operation prevention cover and that protrudes radially outward; an engagement groove provided on the inner circumferential surface, extending axially forward from the rear end surface of the erroneous operation prevention cover and engaging with the engagement protrusion to make the erroneous operation prevention cover unrotatable but movable in the axial direction; A cover rotation prevention mechanism to prevent misoperation. (D) provided on the outer circumferential surface of the connecting member and the inner circumferential surface of the erroneous operation prevention cover, which engage with each other when the erroneous operation prevention cover is positioned on the connection member side, and prevent the connection member and the erroneous operation prevention cover from rotating relative to each other; A connecting member rotation prevention mechanism comprising an engaging protrusion and an engaging recess, and at least one of the engaging protrusion and the engaging recess is provided over the entire circumference of the connecting member or the erroneous operation prevention cover.
