[0012] Compared with the prior art, the advantages and positive effects of the present invention are:
[0013] 1. According to the present invention, a small amount of water may remain on the surface of some fire-fighting tools after use. After the fire-fighting tools are stored inside the tool box, when the water inside the tool box needs to be drained, the two rings are pulled in advance to make the two rings move on the surfaces of the two cross bars. The movement of the two rings on the surfaces of the two cross bars will squeeze the two first springs, thereby compressing the two first springs. At the same time, the movement of the two rings will also drive the two hinged plates to move. The movement of the two hinged plates drives the two I-shaped slides to slide on the surfaces of the multiple convex plates. The movement of the two I-shaped slides drives the two limit rods to move. When the two limit rods are completely moved to the inside of the two slide grooves, the water storage box is inserted into the inside of the water storage frame. When the water storage box is inserted, the two mounting plates are located inside the two mounting grooves. At this time, the two rings can be loosened, and the rebound force of the two first springs is used to make the two limit rods inserted into the corresponding limit holes. The two limit rods The water in the drainage pipe will be discharged into the water storage frame through the drainage hole at the bottom, and the water in the drainage pipe will be discharged into the water storage frame through the drainage hole at the bottom. At the same time, the water in the drainage groove will be directly discharged into the water storage frame, and then into the water storage box. When the water in the tool box is drained into the water storage box, the water storage box can be pulled out and the water inside can be poured out. Through the cooperation of the above structure, the residual water on the surface of the fire-fighting tool can flow into the water storage box along with the drainage component, so as to avoid rusting of the fire-fighting tool during long-term storage, thereby affecting the normal use of the fire-fighting tool.
[0014] When the fire extinguisher is taken out in time, the two push plates are pushed, and the two push plates move to drive the two movable plates to move on the surfaces of the two vertical rods. The movement of the two movable plates will squeeze the two second springs, thereby compressing the two second springs. At the same time, the movement of the two movable plates will also drive the two L-shaped plates to move. The movement of the two L-shaped plates will release the restriction of the clamping plates. At this time, the clamping plates are rotated, and the clamping plates rotate to release the restriction of the fire extinguisher. At this time, the fire extinguisher can be taken out. When it is necessary to re-fix the fire extinguisher, the fire extinguisher is first placed close to the groove on the surface of the fixing plate. At this time, the two push plates are pushed again, and then the clamping plates are rotated to reset. When the clamping plates are able to clamp the fire extinguisher with the groove, the two L-shaped plates are also inserted into the inner limit grooves. At this time, the two push plates can be released, and the rebound force of the two second springs makes the two L-shaped plates move to the limit positions at the upper and lower ends of the limit groove, thereby limiting the movement of the clamping plates, thereby completing the purpose of fixing the fire extinguisher. Through the cooperation of the above structure, the fire extinguisher can be quickly taken out, and the fire can be extinguished in time, thereby improving the practicality of the device.

[0036] In one embodiment, two cross bars 609 are fixedly installed on the surface of one side of the water storage frame 507, and a circular plate 610 is fixedly installed on one end port of the two cross bars 609. The surfaces of the two cross bars 609 are slidably connected with circular rings 611, and the annular side walls of the two circular rings 611 are hinged with hinged plates 612. The ends of the two hinged plates 612 away from the two circular rings 611 are hinged to the two I-shaped slides 607 respectively, and a first spring 613 is fixedly installed between the two circular rings 611 and the two circular plates 610.
[0037] Specifically, the hinge plate 612 drives the I-shaped slide plate 607 to move, and the first spring 613 limits the position of the ring 611 on the surface of the crossbar 609 .
[0038] In one embodiment, the limiting assembly 9 includes two vertical slots 901, which are opened on one side surface of the fixed plate 7. Two vertical rods 902 are fixedly installed between the upper and lower inner walls of the two vertical slots 901. The surfaces of each group of two of the four vertical rods 902 are slidably connected to two movable plates 903, and a push plate 904 is fixedly installed on one end of the one side surface of the multiple movable plates 903.
[0039] Specifically, the push plate 904 drives the movable plate 903 to slide on the surfaces of the two vertical rods 902 .
[0040] In one embodiment, an L-shaped plate 905 is fixedly installed on the other end of one side surface of the multiple movable plates 903, a limiting groove 906 is provided on one side surface of the two clamping plates 701, and the multiple L-shaped plates 905 are grouped in two and pass through the interior of the two limiting grooves 906, and a baffle 907 is fixedly installed on the surface of each group of two of the four vertical rods 902, and a second spring 908 is fixedly installed between the two baffles 907 and the multiple movable plates 903.
[0041] Specifically, the L-shaped plate 905 is inserted into the limiting groove 906 to prevent the clamping plate 701 from rotating, and the second spring 908 limits the position of the movable plate 903 on the surface of the two vertical rods 902.
[0042] Working principle: After use, a small amount of water may remain on the surface of some firefighting tools. When the firefighting tools are stored in the tool box and the water inside the tool box needs to be drained, the two rings 611 are pulled in advance to move the two rings 611 on the surface of the two cross bars 609. The movement of the two rings 611 on the surface of the two cross bars 609 will squeeze the two first springs 613, thereby compressing the two first springs 613. At the same time, the movement of the two rings 611 will also drive the two hinged plates 612 to move, and the movement of the two hinged plates 612 will drive the two I-shaped slides 6 07 slides on the surface of the multiple convex plates 606, and the two I-shaped slides 607 move to drive the two limiting rods 608 to move. When the two limiting rods 608 are completely moved into the two chute 605, the water storage box 604 is inserted into the water storage frame 507. When the water storage box 604 is inserted, the two mounting plates 602 are located inside the two mounting grooves 601. At this time, the two rings 611 can be loosened, and the rebound force of the two first springs 613 is used to make the two limiting rods 608 inserted into the corresponding limiting holes 603. The two limiting rods 608 are inserted into the corresponding limiting holes 603. The rod 608 is plugged into the two limiting holes 603, so that the water box 604 is firmly limited inside the water frame 507. Then the fire-fighting tools are placed on the surface of the storage plate 501 or hung on the hook 401. Since there is a water flow groove on the surface of the storage plate 501 and the drainage plate 502 and the drainage groove 503 are in an inclined state, the water on the surface of the fire-fighting tools flows through the storage plate 501 to the surface of the drainage plate and the drainage groove 503. The water inside the drainage plate 502 flows into the inside of the drain pipe 505 through the drainage hole 504. The water will be drained into the water storage frame 507 through the drainage hole 504 at the bottom. At the same time, the water in the drainage groove 503 will be directly drained into the water storage frame 507, and then flow into the water storage box 604. When the water in the tool box is drained into the water storage box 604, the water storage box 604 can be pulled out and the water inside can be poured out. The above structure allows the water remaining on the surface of the fire-fighting tools to flow into the water storage box 604 along with the drainage component 5, thus preventing the fire-fighting tools from rusting due to long-term storage, thereby affecting the normal use of the fire-fighting tools.When a fire occurs and the fire extinguisher 8 needs to be taken out in time, the two push plates 904 are pushed. The movement of the two push plates 904 drives the two movable plates 903 to move on the surfaces of the two vertical rods 902. The movement of the two movable plates 903 squeezes the two second springs 908, thereby compressing the two second springs 908. At the same time, the movement of the two movable plates 903 also drives the two L-shaped plates 905 to move. The movement of the two L-shaped plates 905 releases the restriction of the clamping plate 701. At this time, the clamping plate 701 is rotated. The rotation of the clamping plate 701 releases the restriction of the fire extinguisher 8. The fire extinguisher 8 can be taken out at this time. When it needs to be re-fixed, first put the fire extinguisher 8 The two push plates 904 are then pushed again, and the clamping plate 701 is rotated to reset. When the clamping plate 701 fits into the groove and can clamp the fire extinguisher 8, the two L-shaped plates 905 are inserted into the limiting groove 906. The two push plates 904 are then released. The rebound force of the two second springs 908 causes the two L-shaped plates 905 to move to the upper and lower extreme positions of the limiting groove 906, thereby restricting the movement of the clamping plate 701 and thus securing the fire extinguisher 8. The above-mentioned structure allows the fire extinguisher 8 to be quickly removed, allowing for timely fire extinguishing, thereby improving the practicality of the device.
