This utility model includes a test chamber, an igniter inside the test chamber, a display screen on the surface of the test chamber, several buttons on the surface of the test chamber, and an adjustment device inside the test chamber. The adjustment device includes a placement block, which is fixedly connected to the test chamber. An electric telescopic rod is fixedly connected to the surface of the placement block, and a bracket is provided at the output end of the electric telescopic rod. This allows for adjustment of the height of the foam board being tested, preventing some foam board samples from igniting during multiple tests, thus avoiding a shortening of the foam board length and an increased distance between the flame and the sample, which would affect the testing results. This improves the effectiveness of the flame-retardant and fireproof foam board flame-retardant testing device.

[0004] In the aforementioned patent, the flame angle is generally fixed to the flame-retardant plate angle during flame-retardant testing. This fixed method can only test the flame-retardant effect at a fixed angle, and cannot test the flame-retardant effect at multiple angles, resulting in incomplete testing results.

[0005] To address these issues, this invention provides a flame-retardant board testing device. Utility Model Content

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0025] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Reference Figures 1 to 4This application provides a flame-retardant board testing device, including a protective box 1. The protective box 1 has a door 4 hinged to its front. A fixing component 2 is provided inside the protective box 1. A detection component 3 is provided on the inner top of the protective box 1. The fixing component 2 includes a rotating rod 23, which is rotatably connected to the left and right inner walls of the protective box 1. A turntable 22 is fixedly installed on the inner end of the rotating rod 23. A connecting rod 24 is fixedly installed on the inner end of the turntable 22. A side panel 25 is fixedly installed on the inner end of the connecting rod 24. A sliding groove 27 is provided inside the side panel 25. A sliding plate 28 is slidably connected inside the sliding groove 27. A clamping plate 26 is fixedly installed on the inner end of the sliding plate 28. A flame-retardant board 8 is inserted between the clamping plates 26.

[0027] Side plates 29 are fixedly installed on the outer ends of side panels 25. A screw 210 is rotatably connected between the two side plates 29. The screw 210 is screwed through the interior of a sliding plate 28. The threads on both sides of the center of the screw 210 have different directions of rotation. The two sliding plates 28 are respectively screwed onto the outer sides of the threads with different directions of rotation of the screw 210. A second motor 211 is fixedly installed on the top of the side plate 29. The output end of the second motor 211 movably passes through the interior of the side plate 29 and is fixedly connected to the screw 210. A first motor 21 is fixedly installed on the outer end of the protective box 1. The output end of the first motor 21 movably passes through the side wall of the protective box 1 and is fixedly connected to the left rotating rod 23.

[0028] In this embodiment, when conducting fire resistance testing on the flame-retardant plate 8, the flame-retardant plate 8 is placed inside the protective box 1 and fixed by the clamps 26 on both sides. When fixed by the clamps 26, the second motor 211 is started. The rotation of the second motor 211 drives the screw 210 to rotate. The rotation of the screw 210 drives the two slide plates 28 to move synchronously in opposite directions inside the slide groove 27, thereby driving the clamps 26 on both sides to move synchronously in opposite directions. The clamps 26 on both sides clamp the two ends of the flame-retardant plate 8 respectively. After clamping, the first motor 21 is started to drive the rotating rod 23 to rotate. The rotation of the rotating rod 23 drives the turntable 22 to rotate. The rotation of the turntable 22 drives the connecting rod 24 and the side panel 25 to rotate, thereby causing the flame-retardant plate 8 to flip, thus realizing the adjustment of the angle of the flame-retardant plate 8. By adjusting the angle of the flame-retardant plate 8, the flame-retardant effect of the flame-retardant plate 8 under different flame angles can be detected, thereby improving the diversity of the test.

[0029] Reference Figures 1 to 4 In one aspect of this embodiment, the detection component 3 includes a first electric slide rail 33, a first track slider 32 is slidably connected to the outer side of the first electric slide rail 33, and a flame nozzle 31 is fixedly installed at the bottom of the first track slider 32, with the flame nozzle 31 located above the flame-retardant plate 8.

[0030] A second electric slide rail 35 is fixedly installed on the inner top of the protective box 1. A second track slider 34 is slidably connected to the outer side of the second electric slide rail 35. A first electric slide rail 33 is fixedly installed at the bottom of the second track slider 34. A collection drawer 7 is inserted into the inner bottom of the protective box 1. An observation glass window 5 is fixedly installed inside the box door 4. Ventilation slots 6 are provided on both the left and right sides of the protective box 1.

[0031] In this embodiment, during testing, the first electric slide rail 33 and the second electric slide rail 35 are activated to drive the first track slider 32 and the second track slider 34 to slide, thereby moving the flame nozzle 31 in the horizontal direction. This changes the position of the flame on the flame-retardant plate 8, ensuring better testing of each position on the flame-retardant plate 8. The box door 4 and the protective box 1 provide protection during testing, the observation window 5 facilitates observation of the internal situation, the ventilation groove 6 facilitates ventilation, and the collection drawer 7 can collect the dust generated during testing and the flame-retardant plate 8 after testing.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] Working principle: When conducting fire resistance testing on the flame-retardant board 8, the flame-retardant board 8 is placed inside the protective box 1 and fixed by the clamps 26 on both sides. When fixed by the clamps 26, the second motor 211 is started. The rotation of the second motor 211 drives the screw 210 to rotate. The rotation of the screw 210 drives the two slide plates 28 to move synchronously in opposite directions inside the slide groove 27, thereby driving the upper and lower clamps 26 to move synchronously in opposite directions. The clamps 26 on both sides clamp the two ends of the flame-retardant board 8 respectively. After clamping, the first motor 21 is started to drive the rotating rod 23 to rotate. The rotation of the rotating rod 23 drives the turntable 22 to rotate. The rotation of the turntable 22 drives the connecting rod 24 and the side panel 25 to rotate, thereby causing the flame-retardant board 8 to flip, thus achieving the fire resistance test. The angle of the flame-retardant plate 8 can be adjusted to detect its flame-retardant effect under different flame angles, thereby improving the diversity of testing. During testing, the first electric slide rail 33 and the second electric slide rail 35 are activated to drive the first track slider 32 and the second track slider 34 to slide, which in turn moves the flame nozzle 31 in the horizontal direction, thereby changing the position of the flame on the flame-retardant plate 8. This ensures that each position on the flame-retardant plate 8 can be better tested during testing. The box door 4 and the protective box 1 provide protection during testing. The observation glass window 5 facilitates observation of the internal situation. The ventilation groove 6 facilitates ventilation. The collection drawer 7 can collect the dust generated during testing and the flame-retardant plate 8 after testing.
