Summary:The present invention relates to a fire hydrant hose reel. According to the present invention, the outer circumferential surface of a first horizontal pipe of a first elbow (out elbow) is inserted into the inner circumferential surface of a first pipe of a second elbow (in elbow), and a snap ring is installed between the inner and outer circumferential surfaces. According to an assembly structure of the present invention, even without a nut, the second elbow and a guide are prevented from falling out of the first horizontal pipe of the first elbow, and frictional resistance when a fire extinguishing water flows from the first horizontal pipe to the first pipe is eliminated. An objective of the present invention is to provide the fire hydrant hose reel capable of preventing separation and reducing pressure loss through smooth flow of the fire extinguishing water. 본 발명은 제1엘보(아웃 엘보)의 제1수평관의 외주면이 제2엘보(인 엘보)의 제1관의 내주면에 삽입되고 그 내외주면 사이에 스냅링이 설치되어, 너트 없이도 제2엘보와 가이드가 제1엘보의 제1수평관에서 빠지는 것을 방지하면서도 소화수가 제1수평관에서 제1관으로 유동할 때의 마찰 저항을 없앤 조립 구조를 갖는 소화전 호스 릴에 관한 것이다.
