Abstract

PURPOSE:To save labor to set an earthquake sensing device for reuse and to enable quick returning of the device to an operative condition, by a method wherein the earthquake sensing device, which swings and is inclined through sensing of the vibration, is naturally returned back to its original state. CONSTITUTION:When an earthquake sensing device 24 swings in excess of a natural return range L resulting from swing of a heater due to earthquake, etc. after the starting of combustion, the center of gravity is moved from G1 to G2, the end of an actuating plate 37 makes contact with a moving plate 28, a claw 29 is released from engagement of it with a gear 13, and the gear is rotated through the return force of a spring 15. A rotary shaft 6 is rotated togetherwith a ring nut 21 to lower a combustion wick for extinguishment. When combustion is restarted with a knob 7 rotated clockwise, the moving plate 28 engages the claw 29 with the gear 13 through the elastic force of a spring 30, the actuating plate is moved in a horizontal direction by pressing the moving plate 28 to move the center of gravity from G2 to G3, and since the earthquake sensing device 24 is brought to a natural return range, the earthquake sensing device 24 is returned back to the state of the center of gravity G1 which had been located before actuation.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seismic device used in a combustor, etc., and in particular, it detects vibrations and allows the oscillating inclined seismic device to move naturally, thereby reducing the trouble of setting it up for reuse. This was done so that the device could be put into operation quickly.

The present invention will be explained below by referring to an embodiment of the small kerosene stove shown in the figure.In the fuel tank of the small kerosene stove), as shown in No. The vibration sensing device (2) is fixed with Nano H31, (3) etc.), and a core is inserted into the pipe (4) which is fixed to the opening drilled in the center of the front of the fuel tank (1). The rotating shaft (6) of the second lower device (5) is loose.

The core-E lower device (5) has a knob (7) on one end, a pinion (10) that can be fitted into a rack (9) with a core support metal (8) and a V-shaped shaft on the other end, and a rotatable roller ( The rotating shafts (6) each equipped with a pipe (4) with a cap

Further, on one end side of the rotating shaft (6), there is a fixing metal fitting H having a threaded groove fixed with a screw, and the threaded groove is movable. 201 fixed ring nano) t2]),
A gear (I3) that is fixed to the holding cylinder 04) and has a through hole (221) into which the bottle (20) is loosely fitted, and an igniter dial (23) that is loosely fitted into the fixing metal fitting (l!1).
etc. are arranged.

The seismic sensing device (2) is formed integrally with a mounting table (25) on which the seismic sensor C.0 is placed so that it can be raised and lowered, and the moon sensing shrine device (2) is connected to a fuel tank. (1) Mounting plate (2G) fixed on top, support bin (1271
A movable plate (28+) rotatably supported by a pawl 09) that meshes with the gear 03 formed at one end of the movable plate (28), and a spring C30 that constantly urges the pawl toward the gear (13). ), etc., and the seismic sensor (21) includes a weight 04 with a substantially inversely convex cross section forming a small diameter portion 6I) at the lower end;
A plastic cap (33i) is fitted onto the small diameter portion 61 of the lower part of the weight so as to completely cover the end thereof, and is in contact with the bottom surface of the mounting table (25), and penetrates through the camp (33) and attaches to the weight (3). A connecting body made of a rod or a chain that is screwed into a screw hole 04 provided in the lower part of the barrel and can be moved up and down, and loosely fitted into the movable plate (through hole T35 bored at the other end of the two barrels). (3G), the through hole S installed in the lower part of the connecting body
It consists of an actuating plate C37) with a diameter larger than 9. In addition, in the normal state, there is a gap (to) between the actuating plate (37) and the movable plate (28j), and the G singing core frame (G,) is the weight (3).
It is the center of gravity.

Figure 5 shows the actuating plate G゛0 due to the vibration of the seismic sensor due to 1M movement.
This shows the state in which the Ii, r mj plate is lifted and the gear 03) and the pawl handle are released, and (G2) shows the moved weights 11', 7.

Figure 6 shows the case where the rotating shaft (6) is rotated in the forward direction to raise the combustion wick again, and the direction in which it engages with the movable plate (2-machimatsume (29) or gear 03) by the return force of the spring (19) is shown. There is a biasing force -C, which suppresses the horizontal direction and ＼ more than when the actuating plate (3 parts) and the seismic sensor (24) swing, so the center of gravity of the weight (321)
G2) moves to (Gs) and the weight (321's natural return range (J-) moves to the inside of the mouth.
,) return to the state.

The present invention is constructed as described above, and when the knob (7) is rotated, the rotating shaft (6), the fixing metal fitting (■), and the gear Q31 are deformed like a ring nut. Since the gear 03) is locked so that it can rotate in reverse, the starter 5k (151) maintains its stored power and the combustion wick rises.

If the seismic sensor 4) sways beyond its natural return range (L) due to shaking of the stove due to an earthquake after combustion has started, its center of gravity will shift from (G, ) to (G2) as shown in Figure 5. The movable plate (2) moves and becomes a pressing force on the end of the actuating plate (37).
8), the gear rotates due to the restoring force of the pawl (2ω and the gear (13), and the spring ++5), but the gear (13) and the ring nut (21) are connected by the pin (2(fi)). Moreover, the spring (ring nano in the state where the power is stored in 151) (2+1 is the screw groove knob (7
) side end, so the rotating shaft (6) rotates together with the ring nano H2+1 t2 The combustion wick descends and extinguishes the fire by °C.

To start combustion again, rotate the knob (7) in the forward direction to start the fire (the movable base is turned on by turning the knob (8), the claw Qo and the gear θ3).
Since the movable plate t28) is urged to engage, it engages immediately, and the movable plate t28) becomes in the horizontal state before operation, so the movable plate t28)
As the actuating plate moves horizontally due to the suppression of □□□, the center of gravity (G2) moves to (G3), and the seismic sensor (
Since it is within the natural return range of 24), the seismic sensor u4) returns to the state of the center of gravity (G1) before activation and stands still.

According to the present invention, as described above, h1 is
In a device that extinguishes a fire by activating a moving plate,
A connecting body is suspended below the weight of the seismic sensor placed on a stand so as to be tiltable, and an operating plate is provided at the bottom of the connecting body, and one end is connected to the core up/down device.1. A movable plate having a pawl that removably engages with a gear and a movable plate with the other end set oppositely above the operating plate is rotatably pivoted to the front N, -4 mounting base, and one end of the movable plate Since a spring is provided on the movable plate that always biases the pawl toward the gear, when the gear is rotated by operating the core up/down device, when the pawl engages with the gear, the movable plate and other parts are The end presses the actuating plate at the bottom of the connector downwards, resulting in '-
It is possible to stand up a tilted seismic sensor,
Just by operating the core lowering device, the vibration sensing device can be automatically loaded for reuse, which improves usability and further enhances safety as no one forgets to load the cord.

In addition, the seismic sensing device of the present invention is constructed into a unit by installing a weight, a movable plate, and other component parts on a stand, and is fixed to a combustor using the stand. Since each component is attached as a main body in a related manner, the seismic sensing device can be assembled separately from the combustor, and moreover, it is less compact, and to provide a seismic sensing device with consistent and stable quality. I can do it.

Furthermore, since a pawl that engages with the gear is provided on the movable plate that rotates as the weight swings, the seismic sensor and the gear can be linked in one part, reducing the number of parts and improving the configuration. This simplifies the process, and allows the operating force of the movable plate by the vibration sensor to be transmitted to the pawl without loss, allowing for reliable separation of the pawl and gear.

Furthermore, since the mounting base of the seismic sensor is fixed to the fuel tank of the combustor, the seismic sensor can be stably held and malfunctions can be prevented. Since 11 units are fixed to each other, the distance between the seismic sensor and the gear can be shortened, which has great effects such as making the seismic device more compact.
