A locking pin 42 is provided which locks into a locking portion 41 provided on the opposite working portion. This locking fitting 39 is also provided with a locking pin 43 on the other end side, and a tension spring 44 is suspended between it and the base plate 11 so that the locking pin 42 mentioned above is always connected to the edge of the operating portion side of the core vertical lever 1γ. O45, which is energized so as to come into contact with 17a, is a linking metal fitting 46 that is pivoted near the locking metal fitting of the board 11, and this is also a lever type, and one end thereof has a locking metal fitting 39. A locking portion 46 for locking the pin 43 is formed. A shaft 48 of a weight 47 extending through the support plate 11b from the base plate 11 is linked to the other end of the link fitting 45. 49 is a fire extinguishing lever pivotally supported in the opening 50 portion of the board 11, one end of which is connected to the operating portion 4;

A fire extinguishing knob of 6° is attached to the front of the unit.

In the figure, reference numeral 61 indicates a return knob for returning the operating body 28 to its original position after release of the suppression, and reference numeral 62 indicates a buffer such as a rubber column that absorbs the impact when the core upper and lower levers return.

In the above configuration, when the core upper and lower knobs 30 are pressed down,
The end edge 2BG of the operating body 28 lowers the operating portion side of the core up/down lever 17. As a result, the operating portion side of the core vertical lever 170 rises, and the auxiliary lever 22 pivoted on this operating portion side.
The shaft hole 24 of is raised. The lever 8 is rotated via the eccentric camshaft 9 fitted into the shaft hole 24, and the lamp wick 4 is raised to a predetermined position. At this time, the locking pin 42 of the lock fitting 39 fits into the locking portion 41 on the operating portion side of the wick up/down lever 17, and the lamp wick 4 is opened and closed in the raised position.

Therefore, the lamp wick 4 is held raised.

Here, since the eccentric shaft portion 9a of the eccentric camshaft 9 is tapered, it fits into the shaft hole 24 without any gap on both the upper and lower sides, and since there is no play between them, the movement of the auxiliary lever 22 remains eccentric. It is transmitted to the camshaft 9 and has the effect of preventing backlash that tends to occur between the two.

On the other hand, if the exposed height of the lamp wick 4 raised as described above does not reach the reference setting height, the wick height is adjusted as follows. That is, when the lamp wick 4 is first raised as shown in FIG. 9 to rotate the eccentric shaft portion 9a of the eccentric camshaft 9. As a result, the eccentric camshaft 9 moves upward as shown by 9' in FIG.

As a result, the lever 8 to which this eccentric camshaft 9 is attached is also shown in FIG.
It rises as shown by ′. Therefore, the rotating shaft 7 fixed to this lever 8 rotates in the direction of arrow a, and the lamp wick 4
The exposed height of will be higher. In other words, the reference exposure height of the lamp wick 4 has been adjusted.

In this embodiment, when the fine adjustment knob 38 is pushed down with the lamp wick 4 raised, the operating body 34 and the fine adjustment fitting 31
The movement is transmitted to the auxiliary lever 22 via the auxiliary lever 22, and the auxiliary lever 22 rotates downward about the pivot portion 23 to the core up/down lever 17. This allows the shaft hole 2 of the auxiliary lever 22 to
The eccentric camshaft 9 fitted to the lamp 4 is lowered, and the lamp wick 4 is lowered via the lever 8.

If the fine adjustment knob 38 is raised from this state, the lamp wick 4 will be raised by the reverse operation. That is, by operating the fine adjustment knob 38 to move the lamp wick 4 up and down, the combustion amount can be adjusted.

The vertical adjustment range of the lamp wick 4 is such that combustion can occur normally.

Next, if you want to extinguish the combustion under such conditions, press down the extinguishing knob 5o. As a result, the acting part 49a of the fire extinguishing lever 49 pushes up the weight side end of the linking metal fitting 45, and the other end of the linking metal fitting 45 rotates downward to lock the locking pin 43 by the locking part 46, that is, to lock the locking pin 43. The lock of the metal fitting 39 is released. With this, the lock fitting 3
The locking dong 42 of 9 is separated from the locking portion 41 of the core up/down lever 17. The core vertical lever 17 is rotated so that the operating portion side thereof is lowered by the biasing force of the tension spring 21, and an auxiliary lever 22 pivotally supported on the operating portion side of the core vertical lever 17 is rotated.
The shaft hole 24 also descends, and the camshaft 9 fitted into this shaft hole 24 also descends, and the lamp wick 4 descends via Leno (-8) to extinguish the fire.

In this embodiment, an auxiliary lever 22 is provided so that the combustion amount can be adjusted, but this combustion amount adjustment mechanism is not necessarily required. Therefore, in this case, the eccentric shaft portion 9a of the eccentric camshaft 9 is the center of the vertical lever 17.
It may be directly fitted into the large hole 19 (in this case, it is not a large hole but the same as the shaft hole 24 provided in the auxiliary lever 22).

In addition, in this embodiment, adjustment holes 12 are provided in the substrate 11 so that adjustments can be made directly from the outside, but this is because the substrate 11 is located on the front side, and this substrate 11 is placed on the tank side (rear side). Once positioned, it can be adjusted directly from the outside in the same way as above.

Effects of the Invention As is clear from the description of the embodiments, the present invention not only allows the wick height to be adjusted very easily, but also allows the wick height to be adjusted by adjusting the shaft itself, which links the wick up/down lever and the wick side lever. Since it is used, there are various advantages such as simplifying the configuration.
