Description

Technical Field

[0001] The utility model mainly relates to the field of heat treatment furnace detection, in particular to a heat treatment furnace with a detection hook. Background Art

[0002] Heat treatment of metals is a very important step in industrial manufacturing, and the temperature control of heat treatment furnaces needs to be strictly controlled. In daily inspections, when encountering heat treatment furnaces without reserved metering holes, thermocouples need to be installed. Thermocouples are commonly used temperature measuring elements in temperature measuring instruments. They directly measure temperature and convert temperature signals into thermoelectric potential signals, which are converted into the temperature of the measured medium through electrical instruments (secondary instruments). However, the temperature measuring rack for the bundled thermocouples required for the inspection is actually inconvenient to carry and cannot adapt to furnaces of various specifications.

[0003] In the invention patent application with application number CN202022488955.X, application publication date 2021.06.21, and titled "A Temperature Measuring Device for a Gas Forging Heat Treatment Furnace", the invention includes a device body, characterized in that: a magnet and a protective cover are fixed to the bottom of the device body, hooks are fixed to both sides of the top of the device body, a signal transmitter is installed on the top of the device body, a thermocouple and a heat insulation board are arranged at the lower part of the interior of the device body, a vacuum chamber is arranged between the heat insulation board and the device body, hot end probes are connected to both sides of the thermocouple, an isolation box is fixed to the top of the thermocouple, and cold end probes extending into the isolation box are connected to both sides of the top of the thermocouple, a transmission line is connected between the thermocouple and the signal transmitter, and an asbestos rope is arranged between the insulation board, the thermocouple and the isolation box. The device quickly takes out the device through the hook, thereby avoiding the user having to use violence to disassemble the side temperature device, thereby causing damage to the device and the heat treatment furnace.

[0004] However, when the device is used to detect a heat treatment furnace, it is still necessary to set up a temperature measuring frame for the bundled thermocouples required for the detection. This placement is time-consuming, labor-intensive and inconvenient to carry, and is not practical for furnaces of various specifications. Utility Model Content

[0010] Furthermore, the ceramic rod is threadedly installed on the surface of the threaded base, and when the heat treatment furnace is tested, the temperature measuring end of the thermocouple is installed on the surface of the ceramic rod through a steel wire.

[0011] Furthermore, the elastic pad forms an elastic structure on the inner side of the crank plate through a clamping spring, and the crank plate is clamped and installed on the surface of the heating plate through a fixed pad and an elastic pad.

[0012] Furthermore, the heating plates are provided with a plurality of them in the heating inner groove, and the quick-release hooks can be installed on the surface of any heating plate according to the detection requirements.

[0013] Furthermore, the surface of the clamping groove is provided with a frosted anti-slip layer.

[0014] 3. Beneficial effects:

[0015] The utility model has a reasonable design. When testing the heating performance of a heat treatment furnace, the quick-release hook is installed on the corresponding heating plate position according to the testing position. The elastic pad in the quick-release hook clamps the heating plate between the fixed pads under the action of the clamping spring. At the same time, the ceramic rod is threadedly installed on the surface of the threaded base.
