Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] like Figure 1 As shown, an industrial thermometer is used to measure the temperature of the internal components of a high-temperature furnace. The industrial thermometer is inserted into the outer furnace wall 1 for installation. Specifically, the industrial thermometer includes a flange 5, a countersunk hole 52 is provided at the upper end of the flange 5, a cover plate 53 is installed at the upper end of the flange 5, the cover plate 53 closes the upper end opening of the countersunk hole 52, and the cover plate 53 is welded and fixed to the flange 5. The flange 5 is fixedly installed on the outer furnace wall 1, and the flange 5 is inserted into the outer furnace wall 1.

[0020] like Figure 1As shown, the flange 5 includes a bottom plate 51 located at the bottom, the bottom plate 51 is located below the countersunk hole 52, the bottom plate 51 is connected to the probe rod 3, the probe rod 3 passes through the bottom plate 51, and the lower end of the probe rod 3 extends out of the bottom of the bottom plate 51. Specifically, the bottom plate 51 is provided with a through hole 511, the through hole 511 is a tapered hole with a larger top and a smaller bottom, and it passes through the bottom plate 51 from top to bottom, the probe rod 3 passes through the through hole 511, and a spherical portion 31 is provided on the upper part of the probe rod 3, the spherical portion 31 is at least partially located in the through hole 511, the outer wall of the spherical portion 31 abuts against the inner wall of the through hole 511, and the probe rod 3 can rotate along the center of the spherical portion 31. After the probe rod 3 rotates along the center of the spherical portion 31 by a certain angle, the friction resistance of the inner wall of the through hole 511 to the outer wall of the spherical portion 31 keeps the suspension state at this angle.

[0021] like Figure 1 As shown, a dashboard 4 is installed on the top of the cover plate 53, and the temperature measuring element in the probe rod 3 is connected to the elements in the dashboard 4 through an electrical circuit.

[0022] like Figure 1 , Figure 2 As shown, an extension plate 32 is installed on the top of the probe rod 3. The extension plate 32 is located above the spherical part 31. The extension plate 32 is a circular ring structure. A groove 321 is provided on the upper end of the extension plate 32. The groove 321 is recessed downward along the upper end surface of the extension plate 32 to form a circular ring. A pressure plate 6 is installed in contact with the groove 321. The bottom of the pressure plate 6 is located in the groove 321. Figure 3 A holder 61 is installed at the upper end of the pressure plate 6. The holder 61 is formed by splicing two halves. A support rod 7 is rotatably installed on the holder 61. A ball head 71 is provided at the bottom of the support rod 7. The ball head 71 is inserted into the holder 61 and can rotate along the center of the ball head 71.

[0023] like Figure 1 , Figure 3 As shown, the support rod 7 is sleeved with a spring 8, the upper end of the spring 8 is abutted with a pressure block 531, and the lower end of the spring 8 is abutted with the pressure plate 6.

[0024] The pressing block 531 is threadedly connected and installed on the cover plate 53, and the lower end of the pressing block 531 extends out of the lower end of the cover plate 53. The pressing block 531 presses down the pressing plate 6 to limit the extending disk 32, so that the probe rod 3 remains in an inclined state. At the same time, the bottom of the probe rod 3 away from the pressing block 531 abuts against the inner furnace wall 2, and the temperature of the inner furnace wall 2 is monitored by the temperature measuring component in the probe rod 3.

[0025] The specific installation steps are:

[0026] ① The flange 5 is fixedly installed on the outer furnace wall 1. In the initial state, the cover plate 53 and the flange 5 are separated so that the countersunk hole 52 remains in an open state.

[0027] ② Rotate the probe rod 3 so that the bottom of the probe rod 3 abuts against the inner furnace wall 2, and the probe rod 3 remains in an inclined hanging state.

[0028] ③ Install the pressing plate 6, insert the pressing plate 6 into the groove body 321, and adjust the rotation position of the ball head 71 of the supporting rod 7 so that the supporting rod 7 and the spring 8 are arranged vertically upward.

[0029] ④ By rotating the cover plate 53, align the bottom of the pressing block 531 on the cover plate 53 with the upper end of the spring 8, buckle the cover plate 53 on the flange 5, and press down the extension plate 32 by screwing in the pressing block 531, so that the probe rod 3 and the inner furnace wall 2 are more closely abutted to improve the heat conduction efficiency. At the same time, by setting the spring 8, it is prevented that the contact force between the probe rod 3 and the inner furnace wall 2 is too large to cause damage to the wall surfaces of both.
