Description

[Detailed Description of the Invention] The present invention relates to an operating device for a fire extinguishing confirmation device for oil stoves and other oil burners.

This type of conventional fire extinguishing confirmation device reads the rotation angle of the operating shaft using a knob integrated with the operating shaft of the combustion wick and a scale provided along this knob, and determines whether the combustion wick is in the ignition position or the extinguishing position. In this case, it is difficult to confirm whether the fire has been extinguished, and if possible, it is preferable to provide a display device that allows this determination to be made at a glance.

The purpose of the present invention is to provide an operating device for a fire extinguishing confirmation device using such a display device. A rotating plate 6 that is swingably provided and rotates by engaging with the operating shaft 5 of the combustion wick.
The rotary plate 6 is provided with an engaging piece 7 which is loosely fitted into the rotary plate 6 and swings the display plate 4 by its rotation.

In the illustrated example, the display part 4a of the display board 4 is color-coded into a fire extinguishing display 2 painted white and an ignition display 3 painted red, and the display board 4 is supported on the machine frame 1 of the seismic fire extinguishing system 8, for example. It is mounted so that it can swing freely on axis 9. A spring 10 is wound around the support shaft 9, thereby swinging the display plate 4 upward so that the ignition display 3 appears in the through hole 12 formed in the frame 11 of the combustor. The operating shaft 5 of the combustion wick is rotated by a knob 13 provided at its tip, and the rotation causes a rack 14 integrated with the combustion wick at the other end.
A gear 15 meshing with the combustion wick rotates to move the combustion wick up and down. When the knob 13 is rotated in one direction, the return spring 16 wound around the operating shaft 5 is wound up, and the locking gear 17 provided integrally with the shaft 5 is rotated. When engaged with the swingable sensing lever 18 of the device 8, the unwinding rotation of the shaft 5 by the spring 16 is prevented and the combustion wick is stopped in the ignition combustion position.

The ignition and combustion position of this combustion wick is arbitrarily adjusted depending on the state of the flame and the like.

The sensing lever 18 is tilted by the vibration of the weight 19 or by the operation of the extinguishing lever 20, and the tilting disengages the locking gear 17 and causes the return spring 16 to unwind. The force causes the operating shaft 5 to rotate in order to lower the combustion wick into the extinguishing position. Reference numeral 21 indicates a protrusion provided on the display board 4, and when the engaging piece 7 of the rotary plate 6 comes into contact with or separates from the protrusion, the display board 4 swings. 22 is knob 13
When the knob 13 is rotated, the pin 22 engages with the engagement piece 7 of the rotary plate 6 and rotates the rotary plate 6 in the direction of rotation.

To explain its operation, when the knob 13 of the operating shaft 5 of the combustion wick is rotated to the winding side of the return spring 16 to raise the combustion wick to the ignition position, the pin 22 of the knob 13 is moved against the rotating plate 6. The engagement piece 7 of the rotary plate 6 engages and rotates.
is separated from the protrusion 21 of the display board 4, so the display board 4
is swung upward by a spring 10, and its ignition display 3
appears in the through hole 12 of the frame 11.

In addition, the sensing lever 18 of the seismic fire extinguishing device 8 is connected to the weight 1.
9 or the fire extinguishing lever 20 and disengages from the locking gear 17, the operating shaft 5 and the knob 13 are released by the unwinding force of the return spring 16.
is rotated in the opposite direction to the above case, causing the combustion wick to fall rapidly, and at the same time, the pin 22 of the knob 13 engages with the rotary plate 6, and its engagement piece 7 engages the protrusion 21 of the display plate 4. The display board 4 rotates to press the fire extinguishing display 2 into the through hole 1.
2, it is swung downward against the biasing force of the spring 10. Since the rotary plate 6 is fitted loosely into the operating shaft 5, even if the operating shaft 5 is rotated a little to adjust the combustion wick, the rotary plate 6 will not be rotated and the display plate 4 will not be accidentally turned off. The display will not change due to shaking.

In this way, according to the present invention, a swingable display board with a fire extinguishing display and an ignition display is provided in conjunction with the operating device of the combustion wick, and each display appears through the through hole, so that the conventional scale etc. It is easier to confirm that a fire has been extinguished compared to a type that reads the number, and even young children can confirm this. In addition, in this invention, the display board is spring-loaded in the direction opposite to the direction in which the combustion wick is swung by the operating section of the operating device when the combustion wick descends, so that the combustion wick suddenly descends when the fire is extinguished. In the vicinity of the lowest point of descent, the downward force of the combustion wick is weakened by the force of the spring, and there is no wick falling sound such as a bang, and there is no need to provide a special spring etc. for this purpose. This has the effect of simplifying the process.

Claims (1)

[Scope of utility model registration request] A wick up-and-down device that has a spring means for accumulating a biasing force that biases the combustion wick in a downward direction when the combustion wick is rotated in an upward direction, and that rapidly lowers the combustion wick by the biasing force of the spring means when a fire extinguishing lever is operated. In an oil combustor equipped with an oil combustor, a display board having a fire extinguishing indicator and an ignition indicator is swingably provided on the machine frame of the oil combustor, and the display board is attached to an operating device for moving the combustion wick up and down. A fire extinguishing confirmation device for an oil combustor is provided with a driving operating section, and the display plate is spring-loaded in a direction opposite to the direction in which the combustion wick is swung by the operating section of the operating device when the combustion wick is lowered. Actuation device.
