から噴射するごとく構成している。Conventional fire extinguishers of this type have a cap that movably supports a breaking shaft attached to the opening of the fire extinguisher body, and a gas cylinder is screwed and held in a threaded portion formed on the cap, so that the breaking shaft is operated. The sealing plate of the cylinder is broken, and the gas inside the cylinder is supplied into the main body through the gas release path formed in the cap, and this gas causes the extinguishing chemical liquid filled in the main body to be released into the siphon pipe and released. It is configured so that the noise is sprayed through a hose.

れたのである。By the way, with the conventional pressurized fire extinguisher having the above structure, if it is left unused for a long period of time (and the extinguishing chemical liquid filled in the fire extinguisher body and the body The steam generated inside the gas cylinder enters the threaded part between the gas cylinder and the cap and corrodes the threaded part, making it impossible to remove the cylinder from the cap when refilling the gas cylinder, for example. In the event of an emergency in which the fire extinguisher liquid or steam enters the gas release path and corrodes the sealing plate that closes the opening of the cylinder, causing a gas leak, it is necessary to actually use the fire extinguisher. The problem was that it was already unusable.

１内に供給すべくしている。4 is a gas cylinder whose opening is closed by a sealing plate 41, and the cylinder 4 is screwed into the screw hole 21a of the boss portion 21 through a seal backing 42 made of soft rubber or the like as shown in the figure. , breaking the seal banking 42 and sealing plate 41 by moving the breaking shaft 3 downward;
The gas in the cylinder 4 is to be supplied into the fire extinguisher main body 1 through the gas discharge path 22.
又、前記ボンベ４の外周壁面には、軟質の樹脂フィルム
４３を被覆し、該ボンベ４の外面が消火器本体１内の消
火薬液等によって腐蝕するのを防止している。Further, the outer circumferential wall surface of the cylinder 4 is covered with a soft resin film 43 to prevent the outer surface of the cylinder 4 from being corroded by the extinguishing chemical liquid in the fire extinguisher main body 1.
更に又、前記口金２には、サイフオン管５を介して前記
消火器本体１内に開口する薬液放出路２３を設けるとと
もに、この放出路２３の出口には、放出ホース２４を取
付けている。Furthermore, the cap 2 is provided with a chemical discharge path 23 that opens into the fire extinguisher main body 1 via the siphon tube 5, and a discharge hose 24 is attached to the outlet of the discharge path 23.
而して本考案は、前記ガスボンベ４の前記口金２への螺
着部Ａに、ゴム等の弾性材料からなる筒状体６を套嵌し
、該筒状体６により前記螺着部Ａ及びガス放出路２２を
弾性的に密閉するごとくしたのである。Accordingly, in the present invention, a cylindrical body 6 made of an elastic material such as rubber is fitted onto the threaded part A of the gas cylinder 4 to the cap 2, and the cylindrical body 6 connects the threaded part A and the cap 2. The gas discharge path 22 is made to be elastically sealed.
即ち、図に示す実施例では、前記口金２のボス部２１に

閉するごとくしたのである。That is, in the embodiment shown in the figure, a cylindrical body 6 is fitted onto the boss portion 21 of the base 2 to elastically open the gas discharge path 22 which is open on the outer peripheral surface of the boss portion 21. While sealing the cylinder 4, the opening side of the cylinder 4 is connected to the cylindrical body 6.
is screwed into the screw hole 21a of the boss part 21 from the lower end opening of the cylinder 4, and the elastic force of the cylinder 6 is applied as the cylinder 4 is screwed into the screw hole 21a. Lower inner peripheral surface 61
As shown in the figure, by enlarging the diameter and bringing it into close contact with the shoulder 45 of the cylinder 4, the fitting part A of the cylinder 40 to the cap 2 is also sealed.
尚、図中７１は、前記口金２の上面に取付ける固定レバ
ー、１２は該レバーγ１に対し揺動可能に枢支した起動
レバーで、この起動レバー７２の操作により前記破壊軸
３を上下移動させるようにしている。In the figure, reference numeral 71 indicates a fixed lever attached to the upper surface of the cap 2, and reference numeral 12 indicates an activation lever pivotably supported to the lever γ1. By operating this activation lever 72, the breaking shaft 3 is moved up and down. That's what I do.
又７３は前記起動レバー７２のレバー支え、１４は前記
レバー支え７３０回動を阻止する安全ピンである。Further, 73 is a lever support for the activation lever 72, and 14 is a safety pin that prevents the lever support 730 from rotating.
本考案は以上の如く構成するもので、使用するに際して

記消火器本体１内にガスが供給されるのである。The present invention is constructed as described above, and when in use, the safety pin 74 is removed to release the rotation prevention of the lever support 73, and then the activation lever 72 is actuated to move the destruction shaft 3 downward. When the seal backing 42 and sealing plate 41 are broken, the high-pressure gas in the cylinder 4 flows out into the gas release path 22, and the pressure of this gas seals the opening of the gas release path 22. The cylindrical body 6 is partially expanded due to its elastic force, and gas is supplied into the fire extinguisher main body 1.

。As is clear from the above explanation, the fire extinguisher of the present invention has a cylindrical body made of an elastic material fitted over the threaded part of the gas cylinder to the mouthpiece, and the cylindrical body allows the threaded part to be connected and the gas to be discharged. Since it is like elastically sealing the passage,
Even if the cylinder is left unused for a long period of time, there is no risk of the extinguishing chemical or steam entering the threaded part to the cap of the cylinder, or even into the gas discharge path. Corrosion of the plate and cylinder can be reliably prevented. Therefore, when refilling the fire extinguisher with chemical solution, the gas cylinder can be easily removed, and gas can be easily removed without causing any gas leaks inside the cylinder. It works reliably even in
しかも、使用時においては、前記ガス放出路の開口部を
密閉している筒状体が、ガスの圧力により容易に変形す
るため、前記ガスの消火器本体内への供給に何ら障害が
生じる虞れはない。Moreover, during use, the cylindrical body that seals the opening of the gas discharge path is easily deformed by the pressure of the gas, so there is a risk that there will be some problem in the supply of the gas into the fire extinguisher body. There is no such thing.
