The operation of these actuating pins 7 is such that the heat fuse sensor constituting the above-described fire detector 6 is connected to the head end of the first actuating pin 7a with a predetermined tension, thereby providing the first actuating pin. The structure is such that the spring 28 provided on the head side of 7a is always pulled backward while compressing.

Therefore, when a temperature of a predetermined size or more is transmitted to the thermal fuse sensor, the thermal fuse sensor is melted down. Accordingly, the first actuating pin 7a, which has been pulled backward, is installed by the restoring force of the spring 28. It is pushed toward the 2nd actuating pin 7b inserted in the hole 24 of 16). On the other hand, the first actuating pin 7b is inserted into the hole 24 in the mounting bracket 16 so as to be free to move, so that the first actuating pin 7a is moved by the restoring force of the spring 28 while the second actuating pin 7b moves freely.

Therefore, when a temperature of a predetermined size or more is transmitted to the thermal fuse sense, the thermal fuse sensor is melted down. Accordingly, the first operating pin 7a pulled backward by the spring 28 is applied to the spring 28 restoring force. This is pushed toward the second actuating pin 7b inserted into the hole 24 of the mounting bracket 16. On the other hand, the second actuating pin 7b is inserted into the hole 24 in the mounting bracket 16 so as to be free to move, so that the first actuating pin 7a is moved by the restoring force of the spring 28, and the second actuating pin 7b is moved. When the back of the actuating pin 7b is pressed, the actuating pin 7b protrudes out of the side wall 1b of the hood 1 and is installed at the tip of the cable 9 of the fire extinguisher, so that the cable 9 is pulled out. By operating the lock mechanism 29 for locking, this lock mechanism 29 releases the lock state of the cable 9, and the extinguishing agent is ejected from the fire extinguisher 4. As shown in FIG.

Here, the lock mechanism 29 is in accordance with the first embodiment of the present invention, as shown in Figure 3, while being closely installed on the outside of the bracket fixture 26, the shaft (26) in the bracket fixture 26 33 and the locking piece 35 which is installed so as to be able to rotate freely and has a locking ring 34 at its tip, and is fixedly connected to the tip of the cable 9. It consists of the fixed piece 37 provided.

In the operation of the first embodiment having such a structure, the first actuating pin 7a and the second actuating pin 7b are linked to each other so that the second actuating pin 7b protrudes out of the bracket fixture 26. While hitting the lower end of the locking piece 35, the locking piece 35 is rotated about the shaft 33 while the locking ring inserted into the locking groove 36 of the fixing piece 37 34) comes out. Therefore, while the cable 9 pulled by the tension spring 11 through the safety lever 10 of the fire extinguisher 4 is pulled toward the safety lever 10, the fire extinguisher 4 causes the extinguishing liquid to be ejected. do.

On the other hand, as another embodiment of the lock mechanism 29 according to the present invention, as shown in Figure 4, the locking fixture 26 while being installed to be freely rotated by the shaft 33, the locking groove The rotating piece 39 which has 38 is comprised, and the fixed engaging piece 40 which is fixed to the front end of the said cable 9, and is caught by the said rotating piece 39. As shown in FIG. In the lock mechanism 29 according to this embodiment, when the second actuating pin 7b strikes the lower end of the pivoting piece 39, the locking mechanism 29 is rotated like a dotted line in FIG. When the angle is rotated at an angle, the fixed locking piece 40 fitted in the locking groove 38 of the rotating piece 39 is pulled out, and the locking groove 38 of the rotating piece 39 is shown in FIG. As shown, since the top wall is formed to be inclined upward, the fixing catching piece 40 is easily pulled out.

As described above, when the fire extinguishing system detects a fire, the device according to the present invention is quickly delivered to the fire extinguisher through a fire extinguisher cable drive device consisting of two operation pins and lock mechanism, so that the extinguishing fluid is released from the fire extinguisher. In addition to being blown out, the operation pin is divided into two members, so even if the connecting bar provided with one operation member is removed from the hood and cleaned and recombined, there is no functional problem at all. Since the lock mechanism locking the cable of the fire extinguisher is operated accurately and smoothly by the operation pin, it is possible to immediately eject the extinguishing liquid in the event of a fire. Can be removed from the hood without functional problems. It will be able to be separated when there is a need to clean easily.
