The screw 213 is threadedly connected to the threaded rod 212. When the No. 1 motor 211 is started, the output shaft of the No. 1 motor 211 rotates, thereby driving the threaded rod 212 to rotate. The rotation of the threaded rod 212 causes the screw 213 threadedly connected to its surface to move to the right. The support plate 214 is arranged on the upper side of the threaded rod 212. The upper surface of the screw 213 is rotatably connected to the lower surface of the rotating plate 215 through bearings. The movement of the screw 213 drives the rotating plate 215 and the support plate 214 to move.

[0036] In this embodiment, the No. 2 motor 216 is arranged in the inner cavity of the screw 213, the output shaft of the No. 2 motor 216 passes through the screw 213 and extends to the upper side of the screw 213 and is fixed to the lower surface of the rotating plate 215, the sealing plate 217 is fixed to the right side of the support plate 214, the No. 2 motor 216 is started, and the output shaft of the No. 2 motor 216 rotates to drive the rotating plate 215 to rotate in the inner cavity of the support plate 214, and the ignition device is started at this time, and various positions of the material can be detected.

[0040] See also Figure 3-4 In order to avoid air pollution, the filtering mechanism 3 in this embodiment includes a filter box 31, a filter screen 32, a fan 33 and a limiter 34. The filter box 31 is fixed at the middle part of the upper surface of the detection box 1. The filter screen 32 is arranged in the inner cavity of the filter box 31 and is used to filter harmful gases. The fan 33 is fixed on the upper surface of the filter box 31 and is used to extract the gas in the inner cavity of the detection box 1. The limiter 34 is arranged in the inner cavity of the filter box 31 and is used to limit the filter screen 32. The fan 33 is started, and the air inlet end of the fan 33 extracts the harmful gases in the inner cavity of the detection box 1 to the inner cavity of the filter box 31 through the air inlet pipe. At this time, the harmful gases will be filtered by the filter screen 32, and the filtered gases can be discharged through the air outlet end of the fan 33.

[0041] Among them, the limiting member 34 includes two fixed blocks 341, two stretching rods 342, two springs 343, two slide plates 344 and two plug blocks 345. The two fixed blocks 341 are respectively fixed on the opposite sides of the left and right side walls of the inner cavity of the filter box 31, and the opposite sides of the two fixed blocks 341 are fixed to the stretching rods 342.

The slide plate 344 is slidably connected to the inner cavity of the fixed blocks 341. The opposite sides of the two slide plates 344 are fixed to the plug blocks 345. The opposite sides of the two plug blocks 345 penetrate the fixed blocks 341 and extend to the opposite sides of the two fixed blocks 341. The slide plates 344 are moved, and the movement of the slide plates 344 drives the plug blocks 345 to move. At this time, the springs 343 and the stretching rods 342 are compressed.

[0042] In this embodiment, the two ends of the spring 343 are fixedly connected to the opposite side of the fixed block 341 and the slide plate 344, and the left and right sides of the filter 32 are provided with slots that are adapted to the size of the plug block 345. The movement of the slide plate 344 causes the plug block 345 to detach from the slot and enter the inner cavity of the fixed block 341, so that the filter 32 can be removed and replaced.

[0043] It should be noted that the front of the filter box 31 is hingedly connected to a box door via a door hinge, and a handle is fixed to the right end of the box door.

[0044] The working principle of the above embodiment is:

[0045] (1) When conducting a fireproofing test on building materials, first start the No. 1 motor 211. The output shaft of the No. 1 motor 211 rotates, thereby driving the threaded rod 212 to rotate. The rotation of the threaded rod 212 causes the screw 213 threadedly connected to its surface to move to the right. When the screw 213 moves, the limit rod fixed on its lower surface moves in the inner cavity of the limit strip, thereby limiting the movement of the screw 213. The movement of the screw 213 drives the rotating plate 215 and the support plate 214 to move. At this time, the pulley fixed on the lower surface of the support plate 214 moves in the inner cavity of the slide strip, thereby limiting the movement of the support plate 214. The movement of 14 can drive the sealing plate 217 to move to the right, and the movement of the sealing plate 217 drives the telescopic rod 23 to extend, which can limit the movement of the sealing plate 217 until the staff can place the building materials on the upper surface of the rotating plate 215 and make the output shaft of the No. 1 motor 211 rotate in the opposite direction, so that the rotating plate 215 and the support plate 214 return to the inner cavity of the detection box 1. In order to conduct a comprehensive inspection of the materials, the No. 2 motor 216 can be started, and the output shaft of the No. 2 motor 216 rotates to drive the rotating plate 215 to rotate in the inner cavity of the support plate 214. At this time, the ignition device is started, and all directions of the materials can be inspected.

[0046] (2) In order to prevent harmful gases released by the materials after testing from being directly discharged into the air, the fan 33 is first started. The air inlet end of the fan 33 draws the harmful gases in the inner cavity of the test box 1 into the inner cavity of the filter box 31 through the air inlet pipe. At this time, the harmful gases are filtered by the filter 32, and the filtered gases can be discharged through the air outlet end of the fan 33. In order to facilitate the removal and replacement of the filter 32, the slide plate 344 is first moved. The movement of the slide plate 344 drives the plug block 345 to move. At this time, the spring 343 and the stretch rod 342 are both compressed, so that the plug block 345 is disengaged from the slot and enters the inner cavity of the fixed block 341, so that the filter 32 can be removed and replaced.
