[0032] See also Figure 1 and Figure 4 , a fireproof metal JP cabinet, comprising:

[0033] JP cabinet 1, the JP cabinet 1 comprises a main cabinet 11, side blind holes 12 are arranged on both sides of the main cabinet 11, a vent hole 13 is arranged on the upper surface of the main cabinet 11, and the side support column 8 is a hot melt glue stick and is arranged inside the side blind hole 12;

[0034] Based on the above, the side blind holes 12 on both sides of the JP cabinet 1 play the role of fixing the side support columns 8, so that the side support columns 8 can fix the fireproof telescopic tube 6, and the vent holes 13 play the role of interconnecting with the fixing block 2, and the air inside the JP cabinet 1 can be extracted at this time.

[0035] like Figure 1-Figure 3 , Figure 5 as well as Figure 6 As shown, the fixing block 2 is arranged at the top of the JP cabinet 1 and is interconnected with the JP cabinet 1, and includes a block body 21, a motor placement slot 22 and a side plate 26, wherein:

[0036] A first blocking groove 25 is provided on both end surfaces of the block 21. A motor placement groove 22 is provided on the top of the block 21. Both end surfaces of the motor placement groove 22 are provided with first air outlets 23. The first air outlet 23 is communicated with the motor placement groove 22. The first air outlet 23 is communicated with the first blocking groove 25 through the first air delivery groove 24. The first blocking groove 25 is communicated with the vent hole 13. Side plates 26 are provided on both sides of the block 21. A guide rod 27 is provided at the bottom end of the side plate 26.

[0037] The side cover 5 is disposed at both ends of the fixing block 2 and includes a second air outlet 52, a second blocking groove 54 and a transverse plate 55;

[0038] The side cover 5 includes a cover plate 51, and a second air outlet 52, a second air delivery groove 53 and a second blocking groove 54 are provided on a side of the cover plate 51 close to the fixed block 2. The second air outlet 52, the second air delivery groove 53 and the second blocking groove 54 are connected to each other and correspond to the first air outlet 23, the first air outlet 23 and the first blocking groove 25 respectively. The second blocking groove 54 is connected to the side blind hole 12;

[0039] Based on the above, the fixed block 2 and the side cover 5 cooperate with each other, so that the JP cabinet 1 is connected with the fixed block 2 and the side cover 5 through the vent hole 13, so that the air inside the JP cabinet 1 can flow through the first sealing groove 25 and the first air delivery groove 24 and then be discharged from the first air outlet 23. Here, the first sealing groove 25 and the second air delivery groove 24 correspond to the second sealing groove 54 and the second air delivery groove 53 respectively. Therefore, here only the first sealing groove 25 and the second air delivery groove 24 are used as examples to illustrate the airflow path, and the airflow path is also explained in the following, and the side cover 5 and the fixed block 2 cooperate with each other to ensure the sealing degree of air when it flows.

[0040] like Figure 1 and Figure 2 As shown, the top cover 3 and the suction mechanism 4 are sequentially arranged inside the motor placement slot 22 from top to bottom, the suction mechanism 4 includes a dual-axis motor 41, the dual-axis motor 41 is connected to the top cover 3 by screws, and is arranged inside the motor placement slot 22, and a fan blade block 42 is arranged at the output shaft of the dual-axis motor 41, and the fan blade block 42 is arranged inside the first air outlet 23;

[0041] Based on the above, the suction mechanism 4 provides suction, and the fan blade block 42 is driven to rotate by energizing the dual-axis motor 41. When the fan blade block 42 rotates, the air in the JP cabinet 1 is sucked out, and the sucked air flows into the interior of the first air outlet 23 through the air vent 13, the first air delivery groove 24 and the second blocking groove 25, and is discharged from the second air outlet 52 under the action of the fan blade block 42, wherein the top cover 3 fixes the dual-axis motor 41, and makes the dual-axis motor 41 and the fixing block 2 connected and fixed to each other.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, the blocking ball 9 is arranged between the first blocking groove 25 and the second blocking groove 54;

[0043] Side support columns 8, which are arranged on both sides of the JP cabinet 1, and the side support columns 8 are hot melt glue sticks;

[0044] The fireproof telescopic tube 6 is arranged between the fixing block 2 and the side support column 8, and openings 63 are arranged on both sides of the sealing frame 61 below, and the guide rod 27 passes through the openings 63;

[0045] A bottom plate 7, which is arranged at the bottom end of the JP cabinet 1;

[0046] Based on the above, the blocking ball 9 is located between the first blocking groove 25 and the second blocking groove 54. At this time, the blocking ball 9 plays a blocking role. When the suction mechanism 4 works to generate suction, the air inside the JP cabinet 1 is sucked out. During the suction process, the blocking ball 9 moves upward under the action of the suction, so that the airflow can normally enter the interior of the first air outlet 23 to achieve normal air discharge. When the suction mechanism 4 stops working, the blocking ball 9 plays a blocking role under the combined action of gravity and external air pressure to prevent external air from entering the JP cabinet again. The fireproof telescopic tube 6 plays a fireproof role on the one hand and a sealing role on the other. The device cooperates with the bottom plate 7, the side plate 26 and the cross plate 55 to wrap the JP cabinet 1 to prevent the JP cabinet 1 from being connected to the outside air, thereby ensuring that the suction mechanism 4 can extract the air inside the JP cabinet 1.

[0047] In actual use of this embodiment, if everything of the JP cabinet 1 is normal, the side support column 8 is in a normal state, and plays a supporting and fixing role for the fireproof telescopic tube 6. At this time, the cabinet door of the JP cabinet 1 can be opened and used normally;

[0048] If an open fire occurs inside the JP cabinet 1, causing the temperature of the entire JP cabinet 1 to rise, the side support column 8 is heated and melted and loses its support capacity, causing the sealing frame 61 below to move downward along the direction of the guide rod 27 and move to the inside of the groove 72. During this process, the rectangular telescopic tube 62 is stretched to achieve the effect of wrapping the entire JP cabinet 1. During the wrapping, the sealing degree of the entire JP cabinet 1 can be ensured. At this time, the dual-axis motor 41 is energized to drive the fan blade block 42 to rotate;

[0049] When the fan blade block 42 rotates, the air inside the JP cabinet 1 is sucked out, and the sucked airflow hits the blocking ball 9, causing the blocking ball 9 to move upward and temporarily lose its blocking ability. The sucked airflow flows through the vent hole 13, the first blocking groove 25, and the first air delivery groove 24, and then enters the first air outlet 23, and is discharged from the second air outlet 52. When the air suction process stops, the blocking ball 9 resumes its blocking effect under the action of gravity and air pressure, so that the external air cannot enter the interior of the JP cabinet 1. At this time, the air inside the JP cabinet 1 is sucked out, so that the oxygen content inside the fireproof telescopic tube 6 is greatly reduced, effectively suppressing the combustion of open flames, and when there is insufficient oxygen, the open flames can be extinguished;

[0050] The JP cabinet 1 uses the suction mechanism 4 and the sealing structure to seal the entire JP cabinet 1 when an open flame occurs, and after the JP cabinet 1 is sealed, the internal air is extracted to reduce the oxygen content, thereby suppressing and extinguishing the open flame.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
