[0002] Flame retardancy testing is an experiment for measuring and evaluating the combustion performance of materials or products, which can reflect the ability of materials or products to prevent or delay combustion when encountering a fire source. There are many methods for flame retardancy testing, and different methods are applicable to different materials or products.

[0003] Most of the fixed mechanisms for objects to be detected in existing flame retardancy testing detectors are fixed structures, and the position distance relative to the burner cannot be adjusted. When the device clamps and fixes different materials, the distance between the material and the flame emitted by the burner is different, which affects the heated temperature and makes the detected data inaccurate. For this reason, we have proposed a detector for detecting the flame retardancy of aviation materials. Content of the Utility Model

Detailed Embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a detector for detecting the flame retardancy of aviation materials, including a detection box 9 and a control box 10 fixedly connected to the top of a support base 15. The support base 15 is hollow inside and vertically connected with an electric telescopic rod 13. The electric telescopic rod 13 is connected inside the support base 15 through a fixed seat 22. The upper end of the electric telescopic rod 13 extends into the detection box 9 and is fixedly connected with a support platform 11 at its top. The support platform 11 is a support platform made of a high-temperature resistant ceramic plate, which plays a role in heat insulation for the top of the electric telescopic rod 13 to avoid damage to the electric telescopic rod caused by long-term high-temperature heating. For example, Figure 2 As shown, in order to improve the stability of the lifting of the support platform 11, guide rods 12 are symmetrically connected to the bottom of the support platform 11 along the electric telescopic rod 13. The bottom of the guide rods 12 extends into the support base 15. The support platform 11 moves up and down driven by the electric telescopic rod 13, which can drive the guide rods 12 to slide, improving the stability of the movement of the support platform 11.

[0020] For example, Figure 2 , 3 As shown, a clamping mechanism for clamping materials is connected to the top of the support platform 11. The clamping mechanism includes L-shaped mounting seats 4 symmetrically connected to the top of the support platform 11. Connecting seats 5 are fixedly connected to the tops of the L-shaped mounting seats 4. Connecting rods 2 penetrate through the connecting seats 5. Clamping plates 3 are fixedly connected to the adjacent sides of the two connecting rods 2. One side of the connecting seat 5 is threadedly connected with a locking screw 6. The end of the locking screw 6 abuts against the connecting rod 2. A number of anti-slip blocks 20 are fixedly connected to one side of the clamping plate 3. A through hole 23 is formed in the connecting seat 5. The connecting rod 2 is coaxially arranged with the through hole 23, and a supporting surface 21 is provided on the outer wall of the connecting rod 2. The end of the locking screw 6 abuts against the supporting surface 21. When clamping materials, the locking screw 6 is rotated to loosen, and the materials are placed between the two clamping plates 3. After placing, the locking screw 6 is rotated. Under the action of the locking screw 6, its end can clamp and fix the connecting rod 2 to realize the fixed clamping of the materials. It is not only simple in structure and easy to operate, but also can realize the up and down sliding of the materials driven by the electric telescopic rod 13, thereby ensuring the accuracy of the material detection data.

[0021] For example, Figure 2As shown in the figure, a burner 7 is fixedly connected to the top of the detection box 9. The burner 7 is directly above the support platform 11. A temperature sensor 18 and a data acquisition device 19 are fixedly connected to the inner wall of the detection box 9. A controller is connected inside the control box 10. The burner 7, the temperature sensor 18, the data acquisition device 19, and the electric telescopic rod 13 are connected to the controller through wires. A sealing door 14 is hinged on one side of the detection box 9. The temperature sensor 18 is an infrared temperature sensor. To facilitate the observation of the materials inside the detection box 9, an observation window is opened on the sealing door 14, and a high-temperature resistant glass is installed in the observation window, which is beneficial for the staff to observe the detection of the internal materials. And to facilitate the staff to repair and install the electric telescopic rod 13, an inspection port 17 is provided on one side of the support base 15, and an inspection door 16 is connected to the inspection port 17. A ventilation port 8 is opened on the side wall of the detection box 9, which can realize the air circulation inside the detection box 9 and ensure the supply of oxygen, thereby realizing the full combustion of the materials. An exhaust fan can be installed at the ventilation port to accelerate the air circulation.

[0022] In summary, when using the detector for detecting the flame retardancy of aviation materials, the burner 7 is connected to the gas supply device through the connecting pipe 1. At the same time, the material to be detected is clamped between the two clamping plates 3, and the locking screw 6 is rotated to fix the position of the connecting rod 2, thereby realizing the stable placement of the material to be detected. And according to the size of the clamped material, the electric telescopic rod 13 is controlled to drive the support platform 11 to lift and adjust, so as to adjust the height of the material placement, improving the practicability of the device. After the placement is completed, the burner 7 is controlled to burn the material to be detected. The combustion data is transmitted to the controller in the control box 10 through the temperature sensor 18 and the data acquisition device 19. A display connected to the controller is set on the control box 10, and the detected data can be displayed.
