A first telescopic rod 12 is fixedly connected to one side of the sealing plate 11, and a first electromagnetic block 13 is fixedly installed on one side of the first telescopic rod 12. A second electromagnetic block 14 is magnetically connected to one side of the first electromagnetic block 13. A connecting plate 15 is fixedly connected to one end of the first telescopic rod 12. Both ends of the connecting plate 15 are fixedly connected to connecting springs 16, and one end of the connecting spring 16 is fixedly connected to an insert block 17. A slot is provided at the top of the inner wall of the box body 1, and the insert block 17 is plugged into the slot. A rack 18 is fixedly connected to one end of the connecting plate 15, and a gear 19 is meshed on one side of the rack 18. A rotating rod is fixedly connected to the middle part of the gear 19, and a worm 20 is meshed on one side of the gear 19. A fixed plate 21 is fixedly connected to one end of the worm 20, and a movable rod 22 is fixedly connected to one side of the fixed plate 21.

A pull rope 23 is arranged at one end of the movable rod 22, and the bottom end of the pull rope 23 is fixedly connected to the protective plate 7.

[0027] The material is clamped and fixed inside the box body 1 by the sample clamp 10, the angle of the burner 9 is adjusted so that the burner 9 is aimed at the part of the material that needs to be tested, the protective door 4 is closed, and the burner 9 is controlled by the controller 3 to perform combustion detection on the material. The gas after combustion is purified by the purification structure inside the exhaust pipe 2 and then discharged. When the power supply line inside the box body 1 is too long due to power-on time and aging of the power supply line, resulting in line heating, and if it is not repaired in time, and then causes a fire during detection, the box body 1 is powered off. When the power is off, the first electromagnetic block 13 and the second electromagnetic block 14 lose their magnetism and no longer attract each other, so that under the action of the connecting spring 16, the plug block 17 is driven to separate from the slot, and the sealing plate 11 is pushed to move to the outside of the mounting block 5, so that the sealing plate 1 1 moves to the bottom of the exhaust port so that the exhaust port remains sealed. When the first telescopic rod 12 connected to the spring 16 moves, the connecting plate 15 drives the rack 18 to move toward the exhaust port, so that the gear 19 drives the rotating rod to rotate along the top of the box body 1. The rotation of the gear 19 drives the worm 20 and the fixed plate 21 to rotate, so that the movable rod 22 rotates to drive the pull rope 23 to contract. The pull rope 23 drives the protective plate 7 to move along the inner wall of the first movable port toward the inside of the fixed groove, thereby exposing the first movable port and the fire extinguisher 6. When the fire extinguisher 6 senses the temperature of the inner wall of the box body 1 and reaches a high temperature or there is an open flame, the fire extinguisher 6 automatically delivers carbon dioxide to the inside of the box body 1, thereby extinguishing the fire inside the box body 1, and preventing the fire inside the box body 1 from burning too much and causing a safety accident.

The movable port and the exhaust port are arranged relative to each other, so that the sealing plate 11 can be moved from the mounting block 5 through the movable port to the bottom of the exhaust port. The limiting rod 24 is plugged into the limiting groove on one side of the limiting block 25, so that the sealing plate 11 can be moved to the bottom of the exhaust port to maintain a stable seal on the exhaust port. When a fire occurs inside the box body 1, the inside of the box body 1 is kept sealed, thereby facilitating the carbon dioxide fire extinguisher 6 to extinguish the fire and improving the fire extinguishing effect.

[0030] like Figures 5 and 6As shown, the connecting plate 15 is located at the telescopic end of the first telescopic rod 12, the top of the connecting plate 15 is slidably connected to the top inner wall of the box body 1, the first electromagnetic block 13 and the second electromagnetic block 14 are both located inside the mounting block 5, one side of the second electromagnetic block 14 is fixedly installed to the inner wall of the box body 1, the first electromagnetic block 13 and the second electromagnetic block 14 are located between the connecting spring 16 and the plug block 17, and the connecting spring 16 is in a compressed state.

[0031] When the box 1 is powered off, the first electromagnetic block 13 and the second electromagnetic block 14 lose their magnetism, and the first electromagnetic block 13 and the second electromagnetic block 14 are no longer attracted to each other, and the connecting spring 16 is no longer in a compressed state. The connecting spring 16 stretches, driving the plug block 17 to move, so that the first telescopic rod 12 extends, thereby driving the connecting plate 15 to move along the top inner wall of the box 1, and pushing the sealing plate 11 to move, so that the sealing plate 11 moves to the bottom of the exhaust port for sealing, thereby improving the sealing inside the box 1, preventing the fire inside the box 1 from extending to the outside of the box 1, expanding the fire, and affecting safety.

[0032] like Figures 5 and 6 As shown, the bottom of the rack 18 is slidably connected to the top inner wall of the box body 1, the top of the rotating rod is rotatably connected to the top inner wall of the box body 1, one end of the worm 20 is rotatably connected to the support plate 26, the top of the support plate 26 is fixedly installed to the top inner wall of the box body 1, the movable rod 22 is rotatably connected to the inside of the fixed groove at one end away from the support plate 26, the pull rope 23 is located inside the fixed groove, the bottom of the fixed groove is communicated with the first movable opening, one end of the pull rope 23 extends through the bottom of the fixed groove to the first movable opening, the protective plate 7 is movably connected to the inner wall of the first movable opening, and both ends of the top of the protective plate 7 are fixedly connected with fixed springs 27, the pull rope 23 is located between the two fixed springs 27, one end of the fixed spring 27 extends through the first movable opening to the inside of the fixed groove, and the top of the fixed spring 27 is fixedly connected to the top inner wall of the fixed groove.

[0033] When the connecting plate 15 moves, it drives the rack 18 to move along the top inner wall of the box body 1, so that the gear 19 drives the rotating rod to rotate along the top inner wall of the box body 1, thereby driving the worm 20 to rotate on both sides of the support plate 26, so that the fixed plate 21 drives the movable rod 22 to rotate, and one end of the movable rod 22 rotates along the inner wall of the fixed groove, so that the pull rope 23 contracts, and the pull rope 23 drives the protective plate 7 to move upward along the inner wall of the first movable opening, so that the protective plate 7 moves into the fixed groove, and the fixed spring 27 contracts, so as to facilitate the exposure of the fire extinguisher 6, so that the fire extinguisher 6 can automatically transport carbon dioxide to the inside of the box body 1 after power failure, so as to facilitate rapid fire extinguishing and improve safety.

[0034] like Figures 2 to 4As shown, a second movable opening is provided on the inner wall of the box body 1 away from the first movable opening, a groove is provided at the bottom of the second movable opening, a movable groove is provided on one side of the groove and located on the inner wall of the box body 1, a second installation groove is provided on the side of the box body 1 close to the controller 3, a second rotating door is provided on one side of the second installation groove and located on one side of the box body 1, the second movable opening is located on one side of the second installation groove, and a cooling device is provided inside the second installation groove.

[0035] The cooling device inside the second installation groove is protected by the second rotating door, and the cooling device is convenient for cooling the inside of the box 1 through the second movable port, the movable port and the groove, so that when the power is cut off inside the box 1 due to poor contact or other problems, the temperature inside the box 1 is high due to testing, and the fire extinguisher 6 automatically senses the high temperature and open flame and will deliver carbon dioxide. Therefore, after the power is cut off, the cooling device is immediately started to cool the inside of the box 1 immediately, so that after the open flame inside the box 1 is extinguished and the temperature drops, the fire extinguisher 6 no longer delivers carbon dioxide, thereby reducing the use of carbon dioxide when no fire occurs, thereby saving resources.

[0036] like Figures 7 and 8 As shown, the cooling device includes a cold air tank 28, a baffle 29 is arranged on one side of the cold air tank 28 and located inside the second movable opening, a second telescopic rod 30 is fixedly connected to the bottom of the baffle 29, a first connecting rod 31 is fixedly connected to one end of the second telescopic rod 30, a moving block 32 is fixedly connected to one end of the first connecting rod 31, a limiting rod 33 is fixedly connected to the bottom of one end of the first connecting rod 31 near the moving block 32, a pressing block 34 is arranged on one side of the cold air tank 28, a second connecting rod 35 is fixedly connected to the top of the baffle 29 near the cold air tank 28, and the second connecting rod 35 is located at the top of the pressing block 34.

[0037] When the box 1 loses power due to poor contact or other problems, the moving block 32 slides downward, and the moving block 32 drives the first connecting rod 31 to move downward, so that the second telescopic rod 30 contracts, and the second contraction rod drives the baffle 29 to move downward to expose the second movable opening. When the baffle 29 moves, it drives the second connecting rod 35 to move downward and press the button 34, so that the cold air tank 28 delivers cold air to the inside of the box 1 through the second movable opening, thereby lowering the temperature inside the box 1, thereby reducing the use of carbon dioxide, which is convenient for saving the use of carbon dioxide fire extinguishers 6.

[0038] like Figures 7 and 8 As shown, the baffle 29 is movably connected to the inner wall of the second movable opening, the second telescopic rod 30 is located inside the groove, the bottom of the second telescopic rod 30 is fixedly installed to the bottom inner wall of the groove, the first connecting rod 31 is located inside the movable groove, and a limiting hole is provided on the bottom inner wall of the movable groove near the second connecting rod 35, the limiting rod 33 is plugged into the limiting hole, the movable block 32 is located on the front side of the box body 1, and the movable block 32 is located on the front side of the box body 1, and it is movably connected to one side of the box body 1.

[0039] When the moving block 32 is moved, the first connecting rod 31 drives the limiting rod 33 at one end to move downward in the moving groove, so that the limiting rod 33 is plugged into the limiting hole to limit the baffle 29, and the other end of the first connecting rod 31 drives the second telescopic rod 30 to contract inside the groove, so that the baffle 29 moves along the inside of the second movable opening toward the inside of the groove, thereby facilitating the exposure of the second movable opening, thereby facilitating the cold air tank 28 to deliver cold air, facilitating the reduction of the temperature inside the box body 1, and at the same time taking out the tested materials inside the box body 1 for subsequent testing.

[0040] Working principle: When in use, the material is clamped and fixed inside the box body 1 through the sample clamp 10, the angle of the burner 9 is adjusted so that the burner 9 is aimed at the part of the material that needs to be tested, and the protective door 4 is closed to control the controller 3 so that the burner 9 performs combustion detection on the material. The gas after combustion is purified by the purification structure inside the exhaust pipe 2 and then discharged. When the power supply line inside the box body 1 is too long due to power-on time and aging of the power supply line, resulting in line heating, and if it is not repaired in time, and then causes a fire during detection, the box body 1 is first powered off. When the power is off, the first electromagnetic block 13 and the second electromagnetic block 14 lose their magnetism and no longer attract each other, so that under the action of the connecting spring 16, the plug block 17 is driven to separate from the slot, and the sealing plate 11 is pushed to move to the outside of the mounting block 5, so that the sealing plate 11 moves When the connecting spring 16 is stretched, the first telescopic rod 12 is pushed to extend, and the connecting plate 15 drives the rack 18 to move along the inner wall of the top of the box body 1 and move toward the exhaust port, so that the gear 19 drives the rotating rod to rotate along the top of the box body 1. The rotation of the gear 19 drives the worm 20 and the fixed plate 21 to rotate, so that the movable rod 22 rotates to drive the pull rope 23 to contract, and the pull rope 23 drives the protective plate 7 to move along the inner wall of the first movable port toward the inside of the fixed groove, thereby exposing the first movable port and the fire extinguisher 6. When the fire extinguisher 6 senses the temperature of the inner wall of the box body 1 and reaches a high temperature or there is an open flame, the fire extinguisher 6 automatically delivers carbon dioxide to the inside of the box body 1, thereby extinguishing the inside of the box body 1 to prevent the fire inside the protective box body 1 from burning too much and causing a safety accident.

[0041] When the box 1 is powered off due to poor contact or other problems, the moving block 32 slides downward, and the moving block 32 drives the first connecting rod 31 to move downward inside the moving groove, and the second telescopic rod 30 connected to one end of the first connecting rod 31 contracts, and the second contraction rod drives the baffle 29 to move along the inner wall of the second movable opening to the inside of the groove to expose the second movable opening. When the baffle 29 moves, it drives the second connecting rod 35 to move downward to press the button 34, so that the cold air tank 28 delivers cold air to the inside of the box 1 through the second movable opening to reduce the temperature inside the box 1, thereby preventing the box 1 from being powered off due to poor contact or other problems. The temperature inside the box 1 is high due to testing, and the fire extinguisher 6 automatically senses the high temperature and open flame and will deliver carbon dioxide. Therefore, after the power is cut off, the inside of the box 1 is immediately cooled down, so that after the open fire inside the box 1 is extinguished, the temperature drops and the fire extinguisher 6 no longer delivers carbon dioxide. The use of carbon dioxide is reduced when no fire occurs, which is convenient for saving resources.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
