ンベ連結構造である。This invention will be described with reference to the embodiment shown in FIGS. One end of the connecting fitting 3 is welded to the gas inlet 2 of the fire extinguisher container 1, a cap nut 4 is fitted to the connecting fitting 3, and a thin groove 5 is provided on the outer circumference of the other end of the connecting fitting 3. 5 is fitted with an elastic metal ring 6 having a diameter larger than the outer diameter of the connecting fitting 3 and a part of a circle cut off, and the inner end surface 4a of the cap nut 4 is restrained by this ring 6 and the cap nut 4 is used. It is a cylinder connection structure of a fire extinguisher device that connects a high-pressure gas cylinder to the connection fitting 3.

結金具３の先端よりはめる。リング３は溝５に入って元
通りの径になって納まる。(Operation) In the above structure, in order to fit the connecting fitting 3 to the ring 6, the diameter of the ring 6 is slightly expanded from the outer circumference of the connecting fitting 3 and fitted from the tip of the connecting fitting 3. The ring 3 enters the groove 5 and is stored in the original diameter.

たり脱落せず確実に連結でき、高圧ガスは漏れることな
く消火剤容器に導入できる。When the cap nut 4 is connected to the outlet of the high-pressure gas cylinder (not shown), the ring 6 of the cap nut 4 can be reliably connected without falling off because the ring 6 hits the inner end surface 4d of the cap nut, and high-pressure gas can be introduced into the extinguishant container without leaking. .
（実施例） 連結金具３と袋ナット４のはめあいについて、連結金具
外周径D1＝18.2mm、袋ナット４の内径D2＝18.3mmとした
場合、リング６の径1.2mmの弾力ある金属線を用い、そ
の外径D3＝19.4mmとし、溝径はリングの内径とほぼ等し
くする。この構造で確実に袋ナット４をリング６で脱落
せず拘束して高圧ガスボンベに接続できる。(Example) As for the fitting between the connecting fitting 3 and the cap nut 4, when the outer diameter of the connecting fitting is D1 = 18.2 mm and the inner diameter of the cap nut 4 is D2 = 18.3 mm, an elastic metal wire with a diameter of the ring 6 of 1.2 mm is used. , Its outer diameter D3 = 19.4 mm, and the groove diameter is almost equal to the inner diameter of the ring. With this structure, the cap nut 4 can be securely restrained by the ring 6 without falling off and connected to the high-pressure gas cylinder.
当然リング６は径が1.2mm以外のものも使用できるが、
その寸法は連結金具、袋ナットの寸法によって決まる。Of course, the ring 6 can be used with a diameter other than 1.2 mm,
The dimensions are determined by the dimensions of the connecting bracket and cap nut.
リングは断面が四角形、円形いずれでも良い。The ring may have a square or circular cross section.
そして、この構造は消火器、消火装置のいずれにも採用
できる。And this structure can be adopted for both a fire extinguisher and a fire extinguisher.
