■ is an interlocking lever with a substantially doglegged side surface whose base is rotatably pivoted on a shaft support base (in Japan, the vertical axis 04), and the tip of the doglegged piece (611) is connected to the movable body part. A roller (63) is attached to the outer plate portion H of the shaft support base (18) using the pivot body (64).
This centering lever (63) is rotatably supported on the centering lever (63).
A dog-shaped hole (66) is transparently provided in front of the horizontally elongated hole. F] Connecting rod (67) is screwed onto D.

Then, when the push-down button attached to the operating end No. 3 of the core raising lever bag is pushed down, the interlocking rod (67) slides through the dogleg-shaped hole 6 (9 and rotates the interlocking lever No. 0) counterclockwise. The roller (621) of the interlocking lever is configured to move the movable body (4 barrels forward). One end of the interlocking lever is locked to the end of the core vertical axis a41, and the other end is fixed to the end of the core vertical axis a41.

When the extinguishing button ff3 at the tip is moved down, the protruding piece σa at the other end moves upward, and this protruding piece σ4 engages the locking shaft 6. Lift the other end of the actuating plate 57 through the scratch and connect the latch (49) and locking shaft (5).
! Disengage from II.

Next, the operation of the above configuration will be explained. First, when the push-down button (681) shown in FIG. (67) moves to the left, the interlocking lever IQ rotates counterclockwise about the core vertical axis Q4).

The rotation of the interlocking lever [F]e causes the roller lock to move the latch shaft movable body (481) from the position shown in Figure 4 (A) to the position shown in Figure 4 (B), and at this time, the latch shaft moves together with the movable body (481). The shaft (4) moves forward, and at the same time the guide pin 6
I rotates the rotary arm 53 in the counterclockwise direction, and by the rotation of this rotary arm 53), the core vertical shaft (14) also rotates with the crank body H.
The core body (6) is rotated in a direction in which the core body (6) is raised. In addition, the latch shaft (4) moves while compressing the spring (5), and when the specified amount of movement is completed, the latch (4) at the other end moves while compressing the spring (5).
It is locked to the locking claw (40 is the locking shaft 69) of the actuating plate 5'7.

At this time, the spring 52 of the latch shaft (42) is compressed to store force, and due to the engagement of the locking shaft and the locking pawl (4e), the latch shaft (42) maintains the stored force of the spring 5z and remains stationary. With the operations up to this point, the core body (6) has completed its rise to the combustion position and is maintained at that combustion position.

Next, the operation of the core body (6) will be explained based on FIG. 2. The core body (6) shown in Figure 2 is the extinguishing position (lowest lowering position)
From this state, the core vertical axis C of the crank operating mechanism surface
As the crank body (l4) rotates counterclockwise, the crank body (lz
is rotated, and at this time, the engagement shaft part α of the crank body 02 moves leftward through the horizontal elongated hole 011, and the crank receiving plate (
9) and the core support fitting (7), the core body (6) is raised. The crank receiving plate (9) can suppress the lateral movement caused by the rotation of the crank body (Iz) by engaging the small diameter part of the tip of the vertical axis α of the core with the vertical elongated hole (II).
The wick (6) moves linearly only in the vertical direction, and instantly rises from the extinguishing position to the combustion position by rotating the wick's vertical axis I by about 60 degrees.

Next, the adjustment of the core height of the raised core body (6) will be explained.

Due to the engagement of the launch (451 and the actuating plate 67) with the end of the locking shaft, the core (6) remains in the raised state unless the engagement is released, but the latch shaft (421 and the latch (4) are screwed together). Therefore, when the rotary knob (4) is rotated, the latch shaft (42 moves slowly in the axial direction with respect to the latch (4ω) which is stationary due to engagement with the locking shaft (59).

By the movement of this latch shaft (4 arms), the core vertical axis 041 also rotates by a small angle via the movable body (48) and the rotating arm, and this slight rotation of the core vertical axis (14J) causes the core body (6) to rotate by a small angle.
The combustion power is adjusted by finely adjusting the core height within a certain range. Once the core height is adjusted in this way, there is no need to adjust the core height every time the core is raised.

Next, automatic fire extinguishing due to earthquakes, etc. will be explained.

When vibration is applied to the instrument and the weight 67) of the vibration-sensing actuating member (to) swings, the other end of the actuating plate (157) is moved upward via the actuating rod (to), and the latch (49) is moved upward. Locking claw (46
) and locking shaft 5! II is released, and the latch shaft (4
21 is instantly moved to its original position by the accumulated force of the spring 152, and the core vertical axis 04) is reversely rotated via the movable body (4 screws and rotating arm 63), causing the core body (6) to suddenly descend. extinguish a fire.

Also, in normal fire extinguishing, if the extinguishing button (73) is pressed down, the other end of the extinguishing lever (7 hot water is the actuating plate 6'7) is moved upward and the core is rotated in the opposite direction along the vertical axis α in the same way as described above. , core body (
6) Can be extinguished by rapidly descending.

Since the present invention is constructed as described above, it has the following effects.

■ The crank operating mechanism for operating the crank body consists of a center lift lever that raises the core body to the combustion position against the biasing force of a core spring, and a locking lever that locks the core body when it has risen to the combustion position. A stop body, a fire extinguishing lever that releases the locked state at the time of extinguishing a fire and suddenly lowers it to the core extinguishing position with I-, and a fire extinguishing lever that moves the core that has been raised to the combustion position up and down to adjust the combustion firepower and A core height adjustment member that regulates the descent to a fixed position, and a seismic sensing operation that detects vibrations such as earthquakes and rapidly lowers the core that has risen to the combustion position to the extinguishing position by releasing the locked state. Since the crank operating mechanism is attached as a unit to the shaft support base fixed to the fuel tank, the parts can be integrated into the shaft support base, simplifying the structure.
The assembly of the crank operating mechanism can be completed before assembly to the fuel tank, improving assembly work efficiency, and the overall shape of the crank operating mechanism can be made compact, making it easy to store assembled parts.

■ By simply moving the operating end of the core raising lever downward, the core can be set for raising the core and automatically extinguishing the fire, improving operability.

■ Equipped with a wick height adjustment member that adjusts the combustion power by moving the wick up and down when it is raised to the combustion position, and also restricts its descent to a fixed position, preventing the wick from lowering too much when it is in the combustion position. This makes it possible to prevent incomplete combustion due to undersized flame combustion and improve safety.
