Abstract: Disclosed is a side bracket for fixing a sprinkler joint. The side bracket for fixing the sprinkler joint includes a distance controller installed at a lower portion of one of side wall supporting portions of the side bracket, wherein the distance controller includes an inclined plate installed at an outer surface of the side wall supporting portion, a rotational member installed along a center line of the inclined plate, and a fixing shaft configured to connect the inclined plate with the rotational member and to pass through and be fixed to the pair of side wall supporting portions.

Abstract: A fixing bracket of a reducer for a sprinkler, the fixing bracket including: a body portion including a bottom wall having a predetermined width and a pair of bather walls which are disposed at both sides of the bottom wall and between which the bottom wall is interposed, wherein an insertion portion through which a reducer is mounted on the body portion, is perforated in a center of the pair of barrier walls; and a coupling portion that is rotatably coupled to one side of the body portion using a hinge shaft, wherein a fastening concave groove is formed in a top end of one side of the bather walls of the body portion, and the coupling portion includes a cover member, a pivoting member that is pivotably coupled to the cover member, and a fastening member that is separably coupled to the pivoting member.

Abstract: A joint apparatus for prevention of explosion includes a bellows tube including an extension section integrally formed at one end of the bellows tube and an annular protrusion interposed between the extension section and the bellows tube; a coupling nut coupled with the bellows tube; and a connection member coupled with the bellows tube while being supported by the annular protrusion. A gap is formed between a the extension section and the connection member and gas discharged from the bellows tube flows along the outer surface of the extension section through the gap and is discharged to an outside through a rear section of the annular protrusion. Since a travelling path of the gas is lengthened, pressure and temperature of the gas are lowered, so that gas explosion is prevented.

Abstract: Disclosed is a flexible hose assembly with a joint. The flexible hose assembly includes a bellows tube including an extension section integrally formed at one end of the bellows tube and an annular protrusion interposed between the extension section and the bellows tube; a coupling nut coupled with the bellows tube; and a connection member coupled with the bellows tube while being supported by the annular protrusion. A gap is formed between a the extension section and the connection member and gas discharged from the bellows tube flows along the outer surface of the extension section through the gap and is discharged to an outside through a screw coupling section between the connection member and the coupling nut. Since a travelling path of the gas is lengthened, pressure and temperature of the gas are lowered, so that gas explosion is prevented.
