Technical Field

[0001] The utility model relates to the technical field of thermocouples, in particular to a thermocouple for reforming furnace which is convenient for disassembly and assembly. Background Technique

[0002] A thermocouple is a commonly used temperature measuring element in temperature measuring instruments. The outer shapes of thermocouples are often very different due to requirements, but their basic structures are roughly the same. They usually consist of main parts such as hot electrodes, insulating sleeve protection tubes and junction boxes, and are usually used in combination with display instruments, recording instruments and electronic regulators. However, when using a thermocouple, it is not convenient to quickly disassemble and assemble it, which affects its use.

[0003] For example, a thermocouple that is convenient for disassembly and replacement disclosed in Chinese Patent CN216899317U includes an installation box, a thermocouple body, an installation bin and a sliding plate. The thermocouple body is installed inside the installation box, and installation slots are provided at both ends inside the installation box.

Bearings are installed at the tops inside the installation bins. The utility model is equipped with installation inserts, L-shaped connecting plates, first extrusion blocks and second extrusion blocks. During use, by squeezing the second extrusion block with the first extrusion block, the second extrusion block is made to push the sliding plate to move, and then the installation insert can be pushed into the installation slot provided on the installation box, so as to fix the installation box and the thermocouple body. The installation of the thermocouple body is relatively convenient.
