Thermocouple is the temperature element commonly used in temperature measuring instrument, it can direct measurement temperature, and temperature signal is turned
Change thermo-electromotive force signal into.In the thermocouple of prior art, hot junction is that measurement end is enclosed in protection sleeve pipe, in measurement due to protecting
The effect that is thermally isolated of protecting pipe causes the presence of measurement error.
The content of the invention it is an object of the invention to provide a kind of thermocouple structure, to solve to be measured in prior art thermocouple
End is sealed in problem of the protection sleeve pipe internal memory in measurement error.
In order to achieve the above object, the technical solution adopted in the present invention is：
A kind of thermocouple structure, it is characterised in that：Including junction block, junction block top is provided with terminal box, and junction block bottom is set
Protection sleeve pipe is connected with, protection its lower end is the mouth of pipe, and bottom is provided with heat-conducting seat, heat-conducting seat left and right sides position in protection sleeve pipe
Corresponding protective case tube wall is vertically provided with chute respectively, and heat-conducting seat arranged on left and right sides corresponds to be slidedly assemblied in chute respectively
In, the thermocouple being made up of a pair of thermocouple wires is also provided with vertically in the protection sleeve pipe, heat conduction is stretched into two thermocouple wire lower ends
Connect as one to form measurement end in seat and in heat-conducting seat, the junction block center is provided with vertical slip through hole, slide logical
Traveller is slidably fitted with hole, traveller lower end is stretched into protection sleeve pipe, and traveller upper end is stretched into terminal box, and traveller top is provided with and connects
Line terminals, two thermocouple wire upper ends are respectively penetrated in traveller and one-to-one corresponding be connected with binding post, and the heat-conducting seat passes through to erect
Straight connecting rod is connected as one with traveller, and heat-conducting seat right side is provided with the screwed hole of vertical insertion heat-conducting seat, is equipped with screwed hole
Screw mandrel, screw mandrel lower end is rotatably installed at the protection its lower end mouth of pipe mouthful wall, and leading screw upper end penetrates in terminal box and fixedly mounts
There is gear one, gear two is rotatablely equipped with the junction block, gear one is engaged with the transmission of gear two, the terminal box top is also
It is rotatablely equipped between knob, and knob and gear two and is connected as one by center connecting shaft.
A kind of described thermocouple structure, it is characterised in that：The traveller upper end left side is connected with limiting stand, junction block top
Portion correspondence limiting stand position is provided with stopper slot.
In the present invention, heat-conducting seat, traveller are connected as one, and upon rotation of the knob, knob is driven by gear one, gear two
Screw mandrel is rotated, and then can make heat-conducting seat, traveller entirety slide downward, and heat-conducting seat is slided down to from protection its lower end pipe
Mouth exposes, and measurement is realized using the measurement end being encapsulated in heat-conducting seat.It is at the end of measurement, heat-conducting seat, traveller is overall upwards
Slide, you can by heat-conducting seat income protection sleeve pipe, can effectively prevent heat-conducting seat from damaging.
The present invention carries out temperature survey using the measurement end in the heat-conducting seat that can be removed and withdraw from protection sleeve pipe, is surveying
At the end of amount can by measurement end together with heat-conducting seat withdraw protection sleeve pipe in, greatly reduce due to be thermally isolated effect produce measurement
Error, has the advantages that easy to use, long working life.
