[0039] like Figure 1-10As shown, a fire extinguishing device in this embodiment includes a box body 1, a box door 2 is provided on the front side of the box body 1, and an alarm light 21 is provided on the box door 2. When a fire occurs, the alarm light 21 is lit, a fire extinguisher 3 is provided in the box body 1, and a nozzle 31 is provided on the fire extinguisher 3. A fire extinguishing hole 4 and a temperature sensing probe 11 are provided on the left side of the box body 1. The temperature sensing probe 11 is used to detect the temperature. When the temperature is higher than the set value, it is judged that a fire has occurred. The nozzle 31 is inserted into the fire extinguishing hole 4, and a sealing mechanism 5 is provided on the box body 1. The sealing mechanism 5 is used to achieve the sealing of the fire extinguishing hole 4. A trigger mechanism 6 is provided in the box body 1, and the trigger mechanism 6 is used to unlock the fire extinguisher 3 and perform the fire extinguishing action;

[0040] The sealing mechanism 5 includes a sealing plate 51 and a rotating shaft 52. The sealing plate 51 is located outside the box body 1. The sealing plate 51 is sealed and fitted with the left side of the box body 1. The sealing plate 51 is used to seal the fire extinguishing hole 4. The rotating shaft 52 is parallel to the left and right directions. The rotating shaft 52 is inserted from the left side of the box body 1. The rotating shaft 52 is rotatably connected to the box body 1. One end of the rotating shaft 52 is fixedly set on the sealing plate 51. A torsion spring 53 is sleeved on the rotating shaft 52. One end of the torsion spring 53 is connected to the box body 1. The other end of the torsion spring 53 is fixedly set with a connecting ring 54. The connecting ring 54 is coaxially fixedly sleeved on the rotating shaft 52. A rotating plate 55 is fixedly set on the rotating shaft 52. The rotating plate 55 Located in the box body 1, a push plate 56 is provided on the rear side of the rotating plate 55, and the push plate 56 is connected to the trigger mechanism 6. The push plate 56 is driven by the trigger mechanism 6 to move in the front-rear direction. Before extinguishing the fire, the fire extinguisher 3 is unlocked by the trigger mechanism 6, and the trigger mechanism 6 drives the push plate 56 to move forward. The movement of the push plate 56 pushes the rotating plate 55 to rotate around the axis of the rotating shaft 52, that is, the rotating shaft 52 is driven to rotate, and the torsion spring 53 is deformed. The rotation of the rotating shaft 52 drives the sealing plate 51 to rotate synchronously, so that the sealing plate 51 stops sealing the fire extinguishing hole 4. After that, the fire extinguisher 3 is triggered by the trigger mechanism 6 to perform the fire extinguishing action, and the fire extinguishing agent in the fire extinguisher 3 is transported from the nozzle 31 to the fire extinguishing hole 4 and then discharged and acts on the fire point to achieve fire extinguishing;

[0041] The trigger mechanism 6 includes an execution component 61 and an unlocking component 62, wherein the execution component 61 is used to control the fire extinguisher 3 to perform a fire extinguishing action, and the unlocking component 62 is used to unlock the fire extinguisher 3, and the unlocking component 62 is connected to the push plate 56;

[0042] The unlocking assembly 62 includes a push rod 621, which is vertically inserted into the pull ring of the safety pin 32 of the fire extinguisher 3. A slider 622 is threadedly connected to the push rod 621. The slider 622 is driven to move forward and backward by the first cylinder 623. The axis of the safety pin 32 is parallel to the moving direction of the slider 622. The cylinder body of the first cylinder 623 is fixedly set on the inner wall of the box body 1. A knob 624 is fixedly set on the top of the push rod 621. The slider 622 is fixedly connected to the push plate 56. After a fire occurs, the slider 622 is driven by the first cylinder 623. The movement of the slider 622 drives the push plate 56 to move synchronously. Meanwhile, the movement of the slider 622 drives the push rod 621 to move synchronously. The push rod 621 drives the safety pin 32 to move, so that the safety pin 32 is pulled out, and the pressure handle 33 on the fire extinguisher 3 can be pressed down normally. After the fire is extinguished, the first cylinder 623 drives the slider 622 to move in the reverse direction to reset, that is, drives the push plate 56 to move in the reverse direction to reset, and the rotating shaft 52 is reset by the elastic action of the torsion spring 53, so that the sealing plate 51 seals the fire extinguishing hole 4 again.

[0043] By rotating the knob 624, the height of the push rod 621 is adjusted to facilitate application to fire extinguishers 3 of different heights;

[0044] The bottom end of the push rod 621 is provided with a chamfer to facilitate the insertion of the push rod 621 into the pull ring of the safety pin 32;

[0045] The actuator assembly 61 includes a pressing block 611, the bottom of which abuts against the pressing handle 33 of the fire extinguisher 3. The pressing block 611 is driven to rise and fall by a second cylinder 612. The cylinder body of the second cylinder 612 is fixedly connected to the box body 1. The bottom of the pressing block 611 is arc-shaped. When a fire occurs, the second cylinder 612 drives the pressing block 611 to descend, so that the pressing block 611 pushes the pressing handle 33 downward, so that the fire extinguisher 3 performs a fire extinguishing action.

[0046] Two baffles 12 are fixedly arranged in the box body 1, and the two baffles 12 are respectively fixedly arranged on both sides of the fire extinguisher 3 to fit together. The baffles 12 are used to realize the horizontal positioning of the fire extinguisher 3, thereby improving the stability of the fire extinguisher 3;

[0047] In summary, by blocking the fire extinguishing hole 4 with the sealing plate 51 and inserting the nozzle 31 into the fire extinguishing hole 4 , it is possible to avoid the nozzle 31 being blocked and affecting the normal operation of the fire extinguisher 3 .

[0048] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
