(To) is a latch mechanism that holds the core body (6) in the combustion position.In detail below, (6) is a latch mechanism that holds the core body (6) in the combustion position. The latch shaft is movably held in the latch shaft, and has a rotary knob at its front end, and is disposed perpendicular to the core vertical axis α4. - is a double-threaded xtJ threaded portion formed at the rear end portion of the latch shaft ring, and a synthetic resin latch is screwed into this male threaded portion. 0 o'clock is a reverse threaded portion formed at the rear end of the latch shaft adjacent to the male threaded portion to have a reverse thread to the male threaded portion, and a nut is attached to the reverse threaded portion. are screwed together to prevent the latch (to the latch) from coming out from the latch shaft (6) when the latch shaft is rotated and the latch shaft is advanced. If the reverse threaded part α is placed in the same direction as the male threaded part -, the latch) and the nut will come into contact with each other, and if the latch shaft (6) is turned further E, the nut will come off, and the latch will eventually come off. However, the present invention prevents this by making the threaded portion Q-shaped in the opposite direction.

The latch member is restrained from rotating with respect to the latch shaft (6) so that the end portion thereof slides in a guide slot (2) formed transparently in the lower surface plate portion (4) of the support base (G).

(to) is a movable body made of synthetic resin that has a loose insertion hole and a guide pin member perpendicular to the loose insertion hole, and a pair of front and rear movement controls are placed at appropriate locations on the way of the latch shaft pushed through the loose insertion hole. It is fixed with a ring 11. The ring is a spring wound around the latch shaft between the shaft support disk (2) and the movable body, and is compressed and stored as the latch shaft (6) moves forward.

The ring is a substantially U-shaped rotating arm whose base is fixed to the core vertical axis α◆ by a screw inside the shaft support base (to), and a pair of opposing arm pieces F4al have a cutout at the tip of each. A notch-shaped engagement groove Mt4 is formed, and both ends of the guide pin ring of the movable body (2) are inserted into and engaged with the inter-engagement groove f414, respectively. v) is an actuating plate whose one end is rotatably supported on the shaft support base (to) by a pin member, and the latch axis - moves forward to the locking shaft (to) attached to this actuating plate (67). When moved, the locking pawl () is locked onto the latch. The other end of the actuating plate (111) is linked to the actuating rod (111) of the vibration sensing mechanism (111), and when the actuating rod (111) is moved upward by the swinging of the weight (b), the actuating plate (V) The other end is lifted by the disc @υ, and the engagement between the latch and the locking shaft is released.

Next, regarding the operating mechanism for operating the crank mechanism αη and the latch mechanism (G), t1'D is an abbreviation of the side surface whose base is rotatably pivoted on the core vertical axis σ4 within the shaft support base (to). It is a letter-shaped interlocking lever, and a roller is attached to the tip of the dogleg-shaped piece -' to make contact with the movable body and move it. The member uses the pivot shaft to support the shaft support base (
This is an operating lever rotatably supported on the outer surface plate (c) of A hole ring is provided transparently through the dogleg-shaped hole, and the linking rod (2) is screwed onto the dogleg-shaped piece υ' of the interlocking lever Iη. When the push-down button attached to the operating end of the operating lever wheel is pressed down, the linking lever f slides through the dogleg-shaped hole and
11) is rotated counterclockwise, and the roller of the interlocking lever II) moves the movable body forward.

The ring is a return spring whose one end is locked to the end of the core vertical axis α4 and whose other end is locked to the end locking part of the operating lever wheel, in order to return the operating lever wheel to its original position. It is energizing.

(C) is also a fire extinguishing lever pivoted on the outer end of the core vertical axis α4, and when the extinguishing button (2) at the tip is moved down, the protrusion (2) at the other end moves upward, and this protrusion ( c) lifts the other end of the actuating plate via the locking shaft to release the engagement between the latch and the locking shaft.

Next, the operation of the above configuration will be explained. First, when the push-down button ■ shown in Fig. 1 is pushed down, the operating lever ring rotates about the pivot body, and the linking rod ■ moves to the left inside the dogleg-shaped hole. Accordingly, the interlocking lever Iυ rotates counterclockwise about the core vertical axis α4.

As the interlocking lever ■ rotates, the roller ■ moves the latch shaft movable body from the position shown in Figure iJJ to the position shown in Figure 5. At this time, the latch shaft wheel moves forward together with the movable body, and at the same time the guide bin So rotates the rotary arm counterclockwise, and the rotation of this rotary arm wheel rotates the core vertical axis α in the direction of raising the core body (6) via the crank body (2). do. In addition, the latch shaft ring moves while compressing the spring ring on one side, and when the predetermined amount of movement is completed, the locking pawl of the latch () on the other end is locked with the locking shaft of ()' is on the operating plate). do. At this time, the spring of the latch shaft (-) is compressed to store force, and the engagement of the locking shaft (2) and the locking pawl ()' causes the latch shaft ring to remain stationary while maintaining the stored force of the spring wheel. Through the operations up to this point, the core body (6) has completed its rise to the combustion position and is held there.

Next, the operation of the core body (6) will be explained based on FIGS. 2 and 3. The three bodies (6) shown in Fig. 2 and 5 are in the extinguishing position (lowest lowered position), and from this state, the crank body υ is rotated with the counterclockwise rotation of the lower shaft α4. While moving the engaging shaft part of the crank body (2) to the left (red horizontal long hole α), remove the crank receiving plate (9) and the core support metal fitting (
7), the core body (6) is raised. and,
The crank support plate (9) can suppress the lateral movement caused by the rotation of the crank body 0 by the engagement between the small diameter part (E) at the tip of the center E lower shaft Q4) and the vertical long hole αQ. The body (6) moves linearly only in the vertical direction, and moreover, the body (6) moves in a straight line only in the vertical direction, and about 6
When rotated 0 degrees, it instantly rises from the extinguishing position to the combustion position.

Next, fine adjustment of the core height of the raised core body (6) will be explained. Due to the engagement between the latch) and the locking shaft ring of the actuating plate (b), the core body (6) remains in the raised state unless the engagement is released, but the latch shaft ring and the latch are connected by screwing. Therefore, when the rotary knob is rotated, the latch shaft (6) slowly moves in the axial direction relative to the latch which is stationary due to engagement with the locking shaft (6). By this movement of the latch shaft (6), the core vertical axis α4 also rotates by a small angle via the movable body-5 rotating arm ring, and this slight rotation of the core vertical axis α causes the center height of the core body (6). will need to be fine-tuned. 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 (B) of the vibration-sensing mechanism (B) swings, the other end of the actuating plate (2) is moved upward via the operating rod (1), and the latch (2) is engaged. The engagement between the locking pawl)' and the locking shaft ring is released, and the latch shaft (6) instantly moves to its original position due to the stored force of the spring ring, and the movable body (goods) and the rotating arm wheel are released. The core vertical axis α4 is reversely rotated through the core, and the core body (6) is suddenly lowered to extinguish the fire.

Also, in normal fire extinguishing, when the extinguishing button handle is pressed down, the extinguishing lever (2) moves the other end of the actuating plate (■) upward, reversely rotates (4) toward the vertical axis of the core (6), and ) can be extinguished by rapidly descending.

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

■ A vibration-sensing mechanism for core raising and automatic extinguishing can be set by simply operating the operating lever, improving operability.

■ The center height can be finely adjusted by rotating the latch shaft, allowing the center height to be set in a good combustion range.

■ Once the center height is adjusted using the latch shaft, there is no need to adjust the center height each time the center is raised, making handling extremely easy.

■ A reverse threaded part is provided for the threaded part of the latch, and the nut is screwed into this reverse threaded part, so even if the latch shaft is rotated more than necessary, the nut will not come off due to the reverse thread, and the latch will hold. It is possible to reliably set the center height and knot within the initially set tolerance range.

■ Since the threaded part is a double thread, the center height can be adjusted with a slight rotation of the latch shaft, making it easy to handle.
