Extra temperature interference is generated, to influence the accuracy of temperature acquisition data；And temperature point molding is efficient and convenient, greatly
Improve the working efficiency layouted.
For this purpose, the tool the technology employed by the present utility model is a kind of thermocouple is layouted, including winding mobile jib and hand
Handle, in the rear end insertion handle of the winding mobile jib, the front end for winding mobile jib is provided with axially extending blind hole, before the blind hole
Port part is provided with the rotation short slot of strip that is parallel with mobile jib axis and communicating with blind hole, and the width W of the rotation short slot is big
It is greater than thermocouple head temperature measuring point in the difference of the diameter of thermocouple leads line, the length L2 of the depth L1 and rotation short slot of blind hole
Length.
The winding mobile jib is made of stainless steel as a preferred embodiment of the above solution, and main body is cylindrical bar, after cylindrical bar
End is rectangular anti-rotation section with cross section, and the handle is wood handle, is provided on wood handle and matches with anti-rotation section
Anti-rotating hole, and anti-rotation section and anti-rotating hole are interference fitted.Using wood handle, the comfort level of gripping is improved；Wood handle and volume
It is connected around mobile jib using anti-rotation structure, wood handle in use process can be effectively avoided to relatively rotate with winding mobile jib.
Further, limited step or limit scratch are provided on the winding mobile jib, limited step or limit scratch are located at
At the position 2-3mm of blind hole rear.Increase limited step or limit scratch, thermocouple leads line twine from the front to the back along winding mobile jib
Until limited step or limit scratch, it is more convenient accurate to operate.
Further, the width W of the rotation short slot is 1.5mm, and length L2 is 5mm, and the depth L1 of blind hole and rotation lack
The difference of the length L2 of slot is 7-10mm.
The utility model has the beneficial effects that the thermocouple head temperature measuring point being rolled into after shape, is surrounded by thermocouple leads line
Always it is in center, head temperature measuring point and non-measured point contact generate extra temperature and interfere when data being avoided to acquire, right
Head temperature measuring point plays the role of effective insulation blocking, to guarantee the accurate reliability of temperature acquisition；And the quick side of molding
Just, working efficiency of layouting is greatly improved.

Fig. 4 is the partial schematic diagram of the thermocouple after being rolled into shape.
Specific embodiment
By way of example and in conjunction with the accompanying drawings, the utility model is described in further detail:
In conjunction with shown in Fig. 1-Fig. 3, a kind of thermocouple is layouted tool, is mainly made of winding mobile jib 1 and 2 two parts of handle.
It winds in the rear end insertion handle 2 of mobile jib 1, handle 2 is set, operator is facilitated to hold.It opens the front end of winding mobile jib 1
There is axially extending blind hole 1a, the front end oral area of blind hole 1a is provided with strip that is parallel with 1 axis of mobile jib and communicating with blind hole 1a
Rotation short slot 1b.The width W for rotating short slot 1b is greater than the diameter of thermocouple leads line, to ensure that thermocouple leads line can be through revolving
Turn short slot 1b to be pierced by.The difference of the length L2 of the depth L1 and rotation short slot 1b of blind hole 1a are greater than the length of thermocouple head temperature measuring point
Degree, to ensure that head temperature measuring point can be completely disposed in blind hole 1a.
Preferably, winding mobile jib 1 is made of stainless steel, and main body is cylindrical bar, and the rear end of cylindrical bar is with cross section
Rectangular anti-rotation section 1c.Handle 2 be wood handle, be provided on wood handle with the matched anti-rotating hole 2a of anti-rotation section 1c, and
Anti-rotation section 1c and anti-rotating hole 2a is interference fitted.
In addition, being provided with limited step or limit scratch (not shown) on winding mobile jib 1, limited step or limit are drawn
Trace is located at the position 2-3mm of the rear blind hole 1a, the spiral section that thermocouple leads line is wound in from the front to the back along winding mobile jib 1, greatly
It is about more than that the circle of thermocouple head temperature measuring point 3 is advisable, convenient for accurately controlling the length for the spiral section that thermocouple leads line is wound in,
Ensure the guard mode best to thermocouple head temperature measuring point 3, while being avoided that spiral section is too long again and being not easy to arrange, operates
