[0013] How to use the fire extinguisher box:

[0014] S1: Open the box cover by the handle, and then the box cover and the rotating shaft will rotate, and then the box cover will open to open the placement opening on the top of the box body. When the box cover is opened, the drawstring will be tightened, and then the slider will be driven to retreat in the hollow groove and compress the first spring. When the slider retreats, the splint will be driven to retreat through the connecting shaft;

[0015] S2: Place the fire extinguisher into the first chamber from the placement opening on the top of the box. At this time, the fire extinguisher enters the interior of the limit ring. Figure 2 As shown, the bottom of the fire extinguisher is located inside the hollow column. After the extinguisher is put in, the box cover is reset by the handle. At this time, the tightened drawstring is relaxed, and then the first spring brings the slider, the connecting shaft, and the clamping plate to reset. The reset clamping plate presses the fire extinguisher against the inside of the limit ring to fix the fire extinguisher.

[0016] S3: The worker opens the box cover by the handle. When opening, the rotating shaft rotates back and forth. The rotation of the rotating shaft drives the first pulley to rotate, and then drives the second pulley to rotate through the belt. When the second pulley rotates, it drives the worm to rotate, and the rotation of the worm drives the worm wheel to rotate. When the worm wheel rotates, the arc rod drives the six arc plates to rotate in the same direction and synchronously to open the hollow column. When the box cover is opened, the draw rope will be tightened and then the fixing effect of the splint on the fire extinguisher will disappear. The top of the third chamber is provided with an opening that matches the through groove. The fire extinguisher that is not fixed will pass through the inside of the hollow column, and then fall into the inside of the circular ring through the through groove and the opening in turn, and then the bottom of the fire extinguisher will hit the second spring, and then the fire extinguisher will shake up and down inside the circular ring to prevent the chemicals in the fire extinguisher from precipitating or agglomerating.

[0017] The beneficial effects of the present invention are:

[0018] 1. Open the box cover by the handle, and then the box cover and the rotating shaft will rotate, and then the box cover will open the placement opening on the top of the box body. When the box cover is opened, the drawstring will be tightened, and then the slider will be driven to retreat in the hollow groove and compress the first spring. When the slider retreats, the splint will be driven to retreat through the connecting shaft, and then the fire extinguisher will be placed in the first chamber from the placement opening on the top of the box body. At this time, the fire extinguisher enters the inside of the limit ring as shown in the figure. Figure 2 As shown, the bottom of the fire extinguisher is located inside the hollow column. After it is put in, the box cover is reset by the handle. At this time, the tightened pull rope will be relaxed, and then the first spring will reset the slider, the connecting shaft, and the clamping plate. The reset clamping plate will press the fire extinguisher against the inside of the limit ring to fix the fire extinguisher.

[0019] 2. The worker opens the box cover by the handle. When opening, the shaft rotates back and forth. The rotation of the shaft drives the first pulley to rotate, and then drives the second pulley to rotate through the belt. When the second pulley rotates, it drives the worm to rotate, and the rotation of the worm drives the worm wheel to rotate. When the worm wheel rotates, the arc rod drives the six arc plates to rotate in the same direction and synchronously to open the hollow column. When the box cover is opened, the draw rope will be tightened and then the fixing effect of the splint on the fire extinguisher will disappear. The top of the third chamber is provided with an opening that matches the through groove. The fire extinguisher that is not fixed will pass through the inside of the hollow column, and then fall into the inside of the ring through the through groove and the opening in turn, and then the bottom of the fire extinguisher will hit the second spring, and then the fire extinguisher will shake up and down inside the ring to prevent the chemicals in the fire extinguisher from precipitating or agglomerating.

The following is an explanation of its embodiments based on the overall structure of the present invention.

[0029] A marine fire extinguisher box and a method of using the same, comprising: a box body 1, a fire extinguisher 7, the box body 1 comprising a first compartment 61, a second compartment 62, and a third compartment 63, the first compartment 61 being used to place the fire extinguisher 7, and a fixing unit 2 for fixing the fire extinguisher 7 is arranged inside the first compartment 61, the fixing unit 2 comprising a box cover 21 arranged on the top of the box body 1, the box body 1 and the box cover 21 are rotatably connected via a rotating shaft 22, one end of the rotating shaft 22 is located outside the box body 1 and fixedly A first pulley 23 is fixed inside the first chamber 61, a limiting ring 24 is fixed inside the limiting ring 24, a hollow groove 25 is provided inside the hollow groove 25, a first spring 26 is provided inside the hollow groove 25 and a slider 27 is slidably connected, a connecting shaft 28 is fixed at one end of the slider 27, one end of the connecting shaft 28 passes through the inside of the limiting ring 24 and is fixed with an arc-shaped clamping plate 29, a pull rope 211 is fixed at one end of the slider 27, and one end of the pull rope 211 is fixedly connected to the bottom of the box cover 21,

[0030] It should be noted that the box cover 21 is opened by the handle 5, and then the box cover 21 and the rotating shaft 22 rotate, and then the box cover 21 opens the placement opening on the top of the box body 1. When the box cover 21 is opened, the pull rope 211 is tightened, and then the slider 27 is driven to retreat in the hollow groove 25 and compress the first spring 26. When the slider 27 retreats, the splint 29 is driven to retreat through the connecting shaft 28, and then the fire extinguisher 7 is placed into the first chamber 61 from the placement opening on the top of the box body 1. At this time, the fire extinguisher 7 enters the interior of the limit ring 24 as shown in FIG. Figure 2As shown, the bottom of the fire extinguisher 7 is then located inside the hollow column 31. After it is placed in, the box cover 21 is reset by the handle 5. At this time, the tightened pull rope 211 will be relaxed, and then the first spring 26 will reset the slider 27, the connecting shaft 28, and the clamping plate 29. The reset clamping plate 29 presses the fire extinguisher 7 against the inside of the limiting ring 24 to fix the fire extinguisher 7.

[0031] Furthermore, an opening and closing unit 3 is provided inside the second chamber 62, and the opening and closing unit 3 includes a hollow column 31 provided between the first chamber 61 and the second chamber 62, the top of the hollow column 31 is located in the first chamber 61, and the bottom of the hollow column 31 is located in the second chamber 62, the bottom of the inner cavity of the second chamber 62 is rotatably connected to a worm wheel 32, a through groove 37 is provided in the middle of the worm wheel 32, six arc plates 33 are rotatably connected to the bottom of the hollow column 31, the top of the worm wheel 32 is rotatably connected to an arc rod 34, and one end of the arc rod 34 is rotatably connected to one end of the arc plate 33, the interior of the second chamber 62 is rotatably connected to a worm 35, and the worm 35 is meshed with the worm wheel 32, one end of the worm 35 is located outside the box body 1 and is fixed with a second pulley 36, the first pulley 23 and the second pulley 36 are connected by a belt, and the six arc plates 33 in the initial state close the hollow column 31,

[0032] It can be concluded that the worker opens the box cover 21 by means of the handle 5. When the box cover 21 is opened, the rotating shaft 22 reciprocates. The rotation of the rotating shaft 22 drives the first pulley 23 to rotate, and then drives the second pulley 36 to rotate through the belt. When the second pulley 36 rotates, it drives the worm 35 to rotate. The rotation of the worm 35 drives the worm wheel 32 to rotate. When the worm wheel 32 rotates, the six curved plates 33 are driven to rotate in the same direction and synchronously through the curved rod 34 to open the hollow column 31. When the box cover 21 is opened, the drawstring 2 is tightened. Then the fixing effect of the clamping plate 29 on the fire extinguisher 7 disappears, and the top of the third chamber 63 is provided with an opening that matches the through groove 37. The fire extinguisher 7 without fixing will pass through the inside of the hollow column 31, and then sequentially pass through the through groove 37 and the opening to fall into the inside of the ring 41. The ring 41 limits the fire extinguisher 7 to prevent it from collapsing when it falls, and then the bottom of the fire extinguisher 7 hits the second spring 45, and then the fire extinguisher 7 shakes up and down inside the ring 41 to prevent the chemicals in the fire extinguisher 7 from settling or agglomerating.

[0033] Next, the third chamber 63 is provided with a shaking unit 4, and the shaking unit 4 includes a circular ring 41 fixed inside the third chamber 63, and a support plate 42 and a pad 43 are slidably connected inside the third chamber 63. A cylinder 413 is fixedly installed at the bottom of the inner cavity of the third chamber 63, and the output end of the cylinder 413 passes through the pad 43 and is fixedly connected to the bottom of the support plate 42. The support plate 42 is penetrated by a circular hole 44, and a second spring 45 is fixed on the top of the support plate 42. The second spring 45 is located at the circular hole 44. On the outside, a rubber top block 46 is fixed on the top of the pad 43, and the top block 46 and the circular hole 44 are located on the same straight line. A vertical groove 47 is provided on the outside of the third chamber 63, and a slide plate 48 is slidably connected along the vertical groove 47. One side of the pad 43 passes through the vertical groove 47 and is fixedly connected to the inner side of the slide plate 48. The outside of the first pulley 23 is rotatably connected to the first connecting rod 411, and the outside of the slide plate 48 is rotatably connected to the second connecting rod 412. One end of the first connecting rod 411 is rotatably connected to one end of the second connecting rod 412.

[0034] It is emphasized that when the first pulley 23 rotates, it will drive the first connecting rod 411 to rotate. When the first connecting rod 411 rotates, it drives the slide plate 48 to slide and rise along the vertical groove 47 through the second connecting rod 412. The rise of the slide plate 48 drives the pad 43 and the top block 46 to rise. The top block 46 rises and penetrates the circular hole 44 to hit the bottom of the fire extinguisher 7. The top block 46 is made of rubber and will not cause damage to the fire extinguisher 7. The circular hole 44 hits the bottom of the fire extinguisher 7 to make the fire extinguisher 7 continue to shake up and down, cooperating with the previous shaking of the fire extinguisher 7 by the second spring 45, to prevent the chemicals in the fire extinguisher 7 from settling or agglomerating to the greatest extent.

[0035] How to use the fire extinguisher box:

[0036] S1: Open the box cover by the handle, and then the box cover and the rotating shaft will rotate, and then the box cover will open to open the placement opening on the top of the box body. When the box cover is opened, the drawstring will be tightened, and then the slider will be driven to retreat in the hollow groove and compress the first spring. When the slider retreats, the splint will be driven to retreat through the connecting shaft;

[0037] S2: Place the fire extinguisher into the first chamber from the placement opening on the top of the box. At this time, the fire extinguisher enters the interior of the limit ring. Figure 2 As shown, the bottom of the fire extinguisher is located inside the hollow column. After the extinguisher is put in, the box cover is reset by the handle. At this time, the tightened drawstring is relaxed, and then the first spring brings the slider, the connecting shaft, and the clamping plate to reset. The reset clamping plate presses the fire extinguisher against the inside of the limit ring to fix the fire extinguisher.

[0038] S3: The worker opens the box cover by the handle. When opening, the rotating shaft rotates back and forth. The rotation of the rotating shaft drives the first pulley to rotate, and then drives the second pulley to rotate through the belt. When the second pulley rotates, it drives the worm to rotate, and the rotation of the worm drives the worm wheel to rotate. When the worm wheel rotates, the arc rod drives the six arc plates to rotate in the same direction and synchronously to open the hollow column. When the box cover is opened, the draw rope will be tightened and then the fixing effect of the splint on the fire extinguisher will disappear. The top of the third chamber is provided with an opening that matches the through groove. The fire extinguisher that is not fixed will pass through the inside of the hollow column, and then fall into the inside of the circular ring through the through groove and the opening in turn, and then the bottom of the fire extinguisher will hit the second spring, and then the fire extinguisher will shake up and down inside the circular ring to prevent the chemicals in the fire extinguisher from precipitating or agglomerating.

[0039] Working principle: through the fixed unit 2, the box cover 21 is opened through the handle 5, and then the box cover 21 and the rotating shaft 22 will rotate, and then the box cover 21 is opened to open the placement opening on the top of the box body 1. When the box cover 21 is opened, the pull rope 211 will be tightened, and then the slider 27 will be driven to retreat in the hollow groove 25 and compress the first spring 26. When the slider 27 retreats, it drives the splint 29 to retreat through the connecting shaft 28.

[0040] Then, the fire extinguisher 7 is placed into the first chamber 61 from the placement opening at the top of the box body 1. At this time, the fire extinguisher 7 enters the interior of the limiting ring 24. Figure 2 As shown, the bottom of the fire extinguisher 7 is located inside the hollow column 31. After the fire extinguisher 7 is put in, the box cover 21 is reset by the handle 5. At this time, the tightened pull rope 211 is relaxed, and then the first spring 26 brings the slider 27, the connecting shaft 28, and the clamping plate 29 to reset. The reset clamping plate 29 presses the fire extinguisher 7 against the inside of the limit ring 24 to fix the fire extinguisher 7, which is helpful to solve the problem that the fire extinguishers 7 cannot be used due to collision when the ship encounters strong winds and waves.

[0041] By setting the opening and closing unit 3 and the shaking unit 4, since the fire extinguisher 7 is stored in the box for a long time, the fire extinguishing agent in the foam fire extinguisher is easy to settle, and the powder in the dry powder fire extinguisher is easy to agglomerate, which will affect the normal use of the fire extinguisher. The process of solving this shortcoming in the present application is as follows: the worker opens the box cover 21 through the handle 5, and when it is opened, the rotating shaft 22 reciprocates, and the rotation of the rotating shaft 22 drives the first pulley 23 to rotate, and then drives the second pulley 36 to rotate through the belt, and when the second pulley 36 rotates, it drives the worm 35 to rotate, and the rotation of the worm 35 drives the worm wheel 32 to rotate, and when the worm wheel 32 rotates, the arc rod The six arc plates 33 are driven by the spring 34 to rotate in the same direction and synchronously to open the hollow column 31. When the box cover 21 is opened, the draw rope 211 is tightened, and then the fixing effect of the clamping plate 29 on the fire extinguisher 7 disappears. The top of the third chamber 63 is provided with an opening that matches the through groove 37. The fire extinguisher 7 that is not fixed will pass through the inside of the hollow column 31, and then fall into the inside of the ring 41 through the through groove 37 and the opening in turn. The ring 41 limits the fire extinguisher 7 to prevent it from collapsing when it falls, and then the bottom of the fire extinguisher 7 hits the second spring 45, and then the fire extinguisher 7 shakes up and down inside the ring 41 to prevent the chemicals in the fire extinguisher 7 from precipitating or agglomerating.

[0042] At the same time, when the first pulley 23 rotates, it will drive the first connecting rod 411 to rotate. When the first connecting rod 411 rotates, it drives the slide plate 48 to slide and rise along the vertical groove 47 through the second connecting rod 412. The rise of the slide plate 48 drives the pad 43 and the top block 46 to rise. The top block 46 rises and penetrates the round hole 44 to hit the bottom of the fire extinguisher 7. The top block 46 is made of rubber and will not cause damage to the fire extinguisher 7. The round hole 44 hits the bottom of the fire extinguisher 7 to make the fire extinguisher 7 continue to shake up and down, and cooperate with the previous shaking of the fire extinguisher 7 by the second spring 45 to prevent the precipitation or agglomeration of chemicals in the fire extinguisher 7 to the greatest extent.

[0043] After the operation is completed, the output end of the cylinder 413 extends to drive the support plate 42 to rise. The output end of the cylinder 413 has four sections that can increase the lifting height of the support plate 42. When the support plate 42 rises, the fire extinguisher 7 and the second spring 45 will pass through the ring 41, the opening, the through groove 37, and the hollow column 31 in sequence, and the fire extinguisher 7 returns to the inside of the limit ring 24, and then the box cover 21 is closed to release the pull rope 211. At this time, the clamping plate 29 is pressed against the fire extinguisher 7 again, and the rotating shaft 22 rotates in the opposite direction when the box cover 21 is closed. Then the six arc-shaped plates 33 seal the hollow column 3. The above operation can make the fire extinguisher 7 return to the first chamber 61 and will not fall again. Then the cylinder 413 drives the support plate 42 to descend and reset. Under normal conditions, the fire extinguisher 7 is placed inside the first chamber 61 and fixed. Only when the fire extinguisher 7 needs to be shaken, the fixing unit will release the fire extinguisher 7, and then the fire extinguisher 7 will enter the third chamber 63. The shaking cycle is once a month. The fixing unit and the shaking unit complement each other and do not cause any contradiction.

[0044] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

A marine fire extinguisher box and a method of using the same according to claim 1, characterized in that: A vertical groove (47) is arranged on the outer side of the third chamber (63), and a slide plate (48) is slidably connected along the vertical groove (47); one side of the pad (43) passes through the vertical groove (47) and is fixedly connected to the inner side of the slide plate (48).

8. A marine fire extinguisher box and a method of using the same according to claim 1, characterized in that: The first pulley (23) is externally rotatably connected to a first connecting rod (411), and the slide plate (48) is externally rotatably connected to a second connecting rod (412).

9. A marine fire extinguisher box according to claim 1, the method of using the fire extinguisher box is as follows: S1: Open the box cover by the handle, and then the box cover and the rotating shaft will rotate, and then the box cover will open to open the placement opening on the top of the box body. When the box cover is opened, the drawstring will be tightened, and then the slider will be driven to retreat in the hollow groove and compress the first spring. When the slider retreats, the splint will be driven to retreat through the connecting shaft; S2: Place the fire extinguisher into the first chamber from the placement opening on the top of the box. At this time, the fire extinguisher enters the interior of the limit ring as shown in Figure 2, and then the bottom of the fire extinguisher is located inside the hollow column. After the fire extinguisher is placed, the box cover is reset by the handle. At this time, the tightened rope will be relaxed, and then the first spring will reset the slider, the connecting shaft, and the clamping plate. The reset clamping plate will press the fire extinguisher against the interior of the limit ring to fix the fire extinguisher. S3: The worker opens the box cover by the handle. When opening, the rotating shaft rotates back and forth. The rotation of the rotating shaft drives the first pulley to rotate, and then drives the second pulley to rotate through the belt. When the second pulley rotates, it drives the worm to rotate, and the rotation of the worm drives the worm wheel to rotate. When the worm wheel rotates, the arc rod drives the six arc plates to rotate in the same direction and synchronously to open the hollow column. When the box cover is opened, the draw rope will be tightened and then the fixing effect of the splint on the fire extinguisher will disappear. The top of the third chamber is provided with an opening that matches the through groove. The fire extinguisher that is not fixed will pass through the inside of the hollow column, and then fall into the inside of the circular ring through the through groove and the opening in turn, and then the bottom of the fire extinguisher will hit the second spring, and then the fire extinguisher will shake up and down inside the circular ring to prevent the chemicals in the fire extinguisher from precipitating or agglomerating.
