All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a device for testing the thermal conductivity of a thermally conductive material, comprising: a testing component 1, a support frame 2 mounted on the surface of the testing component 1, an upper fixing member 4 and a lower fixing member 5 disposed inside the support frame 2, a probe 8 mounted on the side of the testing component 1, a fastening screw 6 mounted on the upper end of the support frame 2, an upper fixing member 4 mounted on the lower end of the fastening screw 6, and a clamping plate 7 mounted inside the upper fixing member 4;

[0021] In use, the thermally conductive material to be tested can be secured in the upper fixing part 4 and the lower fixing part 5 of the device using the clamping plate 7. Then, the fastening screw 6 on the support frame 2 is rotated, and the probe 8 on the side of the detection component 1 is placed between the upper fixing part 4 and the lower fixing part 5. Rotating the fastening screw 6 will move the upper fixing part 4 closer to the lower fixing part 5, thereby fixing the probe 8 between the thermally conductive material to be tested. This makes the fixation of the thermally conductive material to be tested more stable, and at the same time ensures that the probe 8 is in full contact with the material surface, improving the detection accuracy and reliability, simplifying the operation process and improving work efficiency. This avoids the problem of measurement error caused by insecure fixation.

[0022] Embodiment 2: On the basis of Embodiment 1, in order to facilitate the fixed installation of the material to be detected, an upper fixing member 4 is provided. The upper fixing member 4 is integrally in a "冂" - shaped structure. At both ends of the upper surface of the upper fixing member 4, guide plates 12 are fixedly installed. The two groups of guide plates 12 are integrally in a symmetrical structure. The two groups of guide plates 12 are respectively stuck in the limiting holes 10 on both sides of the support frame 2. The two groups of guide plates 12 can be displaced along the limiting holes 10. At the upper end of the inner wall of the upper fixing member 4, two fixing grooves 14 are opened. On both side surfaces of the two ends of the upper fixing member 4, fixing holes are opened. In front of the fixing holes, fixing screw pipes 13 are fixedly installed. A fixing screw 15 is screwed in the fixing screw pipe 13. On one end surface of the fixing screw 15, a clamping plate 7 is installed. Near the end of the fixing screw 15 close to the clamping plate 7, a fixing bearing 11 is installed. The inner ring surface of the fixing bearing 11 is fixedly connected to the outer wall of the fixing screw 15. On one end surface of the clamping plate 7, a fixing slider 3 is fixedly installed. The fixing slider 3 is stuck in the fixing groove 14. The clamping plate 7 can be displaced along the fixing groove 14; The lower fixing member 5 and the upper fixing member 4 are in a symmetrical relationship as a whole. At the lower end of the lower fixing member 5, a support platform is fixedly installed. The support platform is fixedly installed on the upper surface of the detection component 1;

[0023] During installation, the heat - conducting material to be detected can be placed between the clamping plates 7 in the upper fixing member 4 and the lower fixing member 5. Keep the fixing screws 15 at one end of the upper fixing member 4 and the lower fixing member 5 stationary, and press one side of the material to be detected against the side wall of the clamping plate 7 of the stationary end of the fixing screw 15. Then rotate the fixing screw 15 at the other end. At this time, the clamping plate 7 can be displaced along the fixing groove 14 towards the direction of the material to be detected, so as to clamp the material to be detected between the clamping plates 7 in the upper fixing member 4 and the lower fixing member 5, thus facilitating the fixed installation of the material to be detected.

[0024] Embodiment 3: On the basis of Embodiment 2, in order to prevent the probe 8 from being unstable during the detection of the material to be detected, a support frame 2 is provided. The support frame 2 is integrally in a "冂" - shaped structure. An installation hole is opened on the upper surface of the support frame 2. Above the installation hole, a fastening screw pipe 9 is fixedly installed. A fastening screw 6 is screwed in the fastening screw pipe 9. Limiting holes 10 are opened on both sides of the support frame 2; At the lower end of the fastening screw 6, a fixing bearing 11 is provided. The inner ring surface of the fixing bearing 11 is fixedly connected to the outer wall surface of the lower end of the fastening screw 6. The fixing bearing 11 is fixedly installed on the surface of the upper fixing member 4; The detection component 1 is integrally in a square structure. A wiring pipe is fixedly installed on the side surface of the detection component 1. Wires are fixedly installed in the wiring pipe. One end of the wire is electrically connected to a probe 8. The support frame 2 is fixedly installed on the upper surface of the detection component 1;

[0025] To ensure stable contact between the material to be tested and the probe 8 during the overall experiment, when the material to be tested is fixedly installed in the upper fixing member 4 and the lower fixing member 5 respectively, the fastening screw 6 is rotated to move the upper fixing member 4 toward the lower fixing member 5. During the displacement of the upper fixing member 4, under the synergistic action of the fixed bearing 11, the limiting hole 10 and the guide plate 12, the upper fixing member 4 can move along the limiting hole 10 and maintain its overall position angle toward the lower fixing member 5, thereby ensuring that the probe 8 located between the materials to be tested can fully contact the surface of the materials to be tested and firmly fix the probe 8 between the materials to be tested, thus preventing the probe 8 from becoming unstable during the testing process.

[0026] In actual use, the thermally conductive material to be tested can be clamped into the upper fixing part 4 and the lower fixing part 5 of the device by the clamping plate 7, and the fastening screw 6 on the support frame 2 can be rotated. At the same time, the probe 8 on the side of the detection component 1 is placed between the upper fixing part 4 and the lower fixing part 5. Rotating the fastening screw 6 can make the upper fixing part 4 move closer to the lower fixing part 5, thereby fixing the probe 8 between the thermally conductive material to be tested, making the fixation of the thermally conductive material to be tested more stable, and ensuring that the probe 8 is in full contact with the material surface, improving the detection accuracy and reliability, simplifying the operation process and improving work efficiency. This avoids the problem of measurement error caused by insecure fixation.
