This utility model relates to a
thermocouple fixing structure, including a
thermocouple wire groove disposed on any surface of a plate. A
tail fixing position is provided at one end of the
thermocouple wire groove, and a probe fixing position is provided at the remaining end of the
thermocouple wire groove. Several wire-clamping blocks are respectively provided on both sides of the
thermocouple wire groove, following its direction. The advantages are: this structure can be designed into any curved shape and laid on the plate surface according to actual
temperature measurement needs, breaking through the strict limitations of traditional fixing methods on the position and path of the
temperature measurement point; the
tail fixing position, probe fixing position, and wire-clamping blocks constitute a multi-level fixing
system. During installation, the
thermocouple wire is simply pressed into the thermocouple wire groove to complete the installation, effectively solving the problems of complex installation and insecure fixing in existing technologies, and achieving convenient, reliable, and accurate surface
temperature measurement.
