The installation frame 3 is the carrier of the adjusting mechanism 4, and multiple groups of adjusting mechanisms 4 are provided thereon for precisely adjusting the position of the thermocouple 6. Through the adjusting mechanism 4, the operator can conveniently adjust the position of the thermocouple 6 in the furnace to meet different temperature measuring requirements. The installation cylinder 5 is fixed at the adjusting end of the adjusting mechanism 4 and is used for fixedly installing the thermocouple 6. The thermocouple 6 is the core component of the temperature measuring device. The thermocouple 6 is responsible for converting the temperature in the furnace into an electrical signal output for subsequent temperature display. Through the installation of the limiting member 10 and the limiting groove 7, the installation frame 3 can be installed on the connecting frame 2 in a limited and movable manner, so that multiple groups of adjusting mechanisms 4 on the installation frame 3 can rotate and adjust the orientation of the thermocouple 6 on the adjusting mechanism 4. Through the setting of the positioning member 15 and the positioning groove 9, when the positioning member 15 moves into the positioning groove 9, it can accurately position the adjusted installation frame 3, facilitating the operator to adjust the position of the thermocouple 6 on the adjusting mechanisms 4 in different orientations and improving the practicability of the temperature measuring device.

[0021] Please refer to Figure 3 and Figure 4 , Multiple groups of limiting sliding grooves 11 are provided on the limiting member 10. Multiple groups of universal balls 8 are movably provided inside the limiting groove 7, and the universal balls 8 can cooperate with the limiting sliding grooves 11.

[0022] Please refer to Figure 2 and Figure 4, a bidirectional lead screw 12 is rotatably arranged inside the limiting member 10. Two sets of lead screw nuts 13 are meshed on the bidirectional lead screw 12. A frame body 14 is fixedly arranged on the lead screw nut 13. Multiple positioning members 15 are fixedly arranged on the frame body 14, and the positioning member 15 can cooperate with the positioning groove 9. Multiple telescopic limiting guide rods 16 are fixedly arranged inside the limiting member 10, and the output end of the telescopic limiting guide rod 16 is fixedly connected to the outside of the frame body 14. A first gear 17 is fixedly arranged on the bidirectional lead screw 12. A rotating rod 18 is rotatably arranged inside the limiting member 10. A second gear 19 is fixedly arranged at one end of the rotating rod 18, and the second gear 19 meshes with the first gear 17. A knob 20 is rotatably arranged outside the limiting member 10, and one end of the knob 20 is fixedly connected to the outside of one end of the rotating rod 18. When the user rotates the knob 20, the knob 20 drives the rotating rod 18 to rotate. The rotation of the rotating rod 18 is transmitted to the first gear 17 through the second gear 19, thereby driving the bidirectional lead screw 12 to rotate. The rotation of the bidirectional lead screw 12 causes the lead screw nut 13 meshed with it to move along its axis direction. The movement of the lead screw nut 13 drives the frame body 14 and the positioning member 15 thereon to move together. The telescopic limiting guide rod 16 provides necessary support and guidance for the movement of the frame body 14 to ensure its stable and accurate movement. As the positioning member 15 moves, one end of it will enter into the positioning groove 9, and position the mounting frame 3 through the positioning groove 9. The operator can conveniently fix the mounting frame 3 at the required position and perform precise adjustment.

[0023] Working principle: The support frame 1 is the basic support structure of the entire temperature measuring device. The support frame 1 is responsible for carrying and fixing other components to ensure the stability of the entire device in a high-temperature environment. The connecting frame 2 is located at the bottom of the support frame 1 and serves to connect the support frame 1 and the mounting frame 3. The mounting frame 3 is the carrier of the adjusting mechanism 4, and multiple groups of adjusting mechanisms 4 are provided thereon for precisely adjusting the position of the thermocouple 6. Through the adjusting mechanism 4, the operator can conveniently adjust the position of the thermocouple 6 in the furnace to meet different temperature measurement requirements. The mounting cylinder 5 is fixed on the adjusting end of the adjusting mechanism 4 for fixedly installing the thermocouple 6. The thermocouple 6 is the core component of the temperature measuring device, and the thermocouple 6 is responsible for converting the temperature in the furnace into an electrical signal output for subsequent temperature display. Through the installation of the limiting member 10 and the limiting groove 7, the mounting frame 3 can be installed on the connecting frame 2 in a limited and movable manner, so that multiple groups of adjusting mechanisms 4 on the mounting frame 3 can rotate and adjust the orientation of the thermocouple 6 on the adjusting mechanism 4. Through the setting of the positioning member 15 and the positioning groove 9, when the positioning member 15 moves into the interior of the positioning groove 9, it can accurately position the adjusted mounting frame 3, facilitating the operator to adjust the position of the thermocouple 6 on the adjusting mechanisms 4 in different orientations and improving the practicability of the temperature measuring device. The universal ball 8 moves inside the limiting groove 7 and can cooperate with the limiting chute 11, and it is used to assist the rotation of the mounting frame 3. The rolling contact mode of the universal ball 8 helps to reduce friction and wear and improve the movement efficiency and service life of the mechanism or component. When the user rotates the knob 20, the knob 20 drives the rotating rod 18 to rotate. The rotation of the rotating rod 18 is transmitted to the first gear 17 through the second gear 19, and then drives the bidirectional lead screw 12 to rotate. The rotation of the bidirectional lead screw 12 causes the lead screw nut 13 engaged with it to move along its axis. The movement of the lead screw nut 13 drives the frame body 14 and the positioning member 15 thereon to move together. The telescopic limiting guide rod 16 provides necessary support and guidance for the movement of the frame body 14 to ensure its stable and accurate movement. As the positioning member 15 moves, one end of it will enter the interior of the positioning groove 9, and the mounting frame 3 can be positioned through the positioning groove 9. The operator can conveniently fix the mounting frame 3 at the required position and perform precise adjustment.
