Abstract
The invention discloses a kind of mounting structure of thermocouple; include junction block; junction block bottom connects protection sleeve outer wall screw thread and is provided with nut vertically; nut bottom is connected with plush copper; protection sleeve outer wall is located at nut lower section and is provided with multiple kellies by axis of rotation, and torsion spring is separately installed with the rotating shaft of each kelly.Auto-lock function is capable of achieving in the present invention, is greatly facilitated and is used.
Description
Technical field
The present invention relates to area of thermocouples, specifically a kind of mounting structure of thermocouple.
Background technology
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.Prior art thermocouple its mounting means has flange form, nut type etc., can not be formed when mounted
Auto-lock function is locked, it is necessary to separately set the modes such as lockhole in installation site.
The content of the invention it is an object of the invention to provide a kind of mounting structure of thermocouple, to solve prior art thermocouple
Install cannot self-locking problem.
In order to achieve the above object, the technical solution adopted in the present invention is：
A kind of mounting structure of thermocouple, includes junction block, and junction block top is provided with terminal box, and junction block bottom connects vertically
There is protection sleeve pipe, thermocouple be provided with protection sleeve pipe, it is characterised in that：Protection sleeve outer wall forms external screw thread, and protective case
Screw thread is provided with nut on pipe, and nut bottom is connected with plush copper, and the protection sleeve outer wall is located at nut lower section and is turned by rotating shaft
Dynamic to be provided with multiple kellies, multiple kellies are circumferentially uniformly distributed, and each kelly can turn to be opened to outside protection sleeve pipe, each
Torsion spring is separately installed with the rotating shaft of kelly.
A kind of mounting structure of described thermocouple, it is characterised in that：Plush copper is driven to rotate to compressing each by nut
Kelly, so that each kelly is to opening outside protection sleeve pipe.
In the present invention, when protection sleeve pipe is stretched into measured hole, keep protection sleeve pipe motionless, plush copper edge is made by rotating nut
Protection sleeve pipe is moved down, and plush copper compresses kelly, so that kelly is distinguished to being opened outside protection sleeve pipe using nut and each kelly
It is clamped in measured hole upper and lower surface, you can realize auto-lock function, locking mechanism is increased without other near measured hole,
To be moved on nut and plush copper first when using after finishing, then integrally move down protection sleeve pipe, kelly resets under torsion spring effect,
Protection sleeve pipe can be exited from measured hole, greatly facilitate and use.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 uses schematic diagram for the present invention.
Specific embodiment
As shown in Figure 1 and Figure 2, a kind of mounting structure of thermocouple, includes junction block 1, and the top of junction block 1 is provided with wiring
Box 2, the bottom of junction block 1 is connected with protection sleeve pipe 3 vertically, and thermocouple is provided with protection sleeve pipe 3, and the protection outer wall of sleeve pipe 3 is formed
Screw thread is provided with nut 4 on external screw thread, and protection sleeve pipe 3, and the bottom of nut 4 is connected with plush copper 5, and protection sleeve pipe 3 outer wall is located at spiral shell
Female 4 lower section is rotatablely equipped with multiple kellies 7 by rotating shaft 6, and multiple kellies 7 are circumferentially uniformly distributed, and each kelly 7 can turn to
To being opened outside protection sleeve pipe 3, torsion spring is separately installed with the rotating shaft 6 of each kelly 7.Plush copper 5 is driven to rotate to supporting by nut 4
Each kelly 7 is pressed, so that each kelly 7 is to opening outside protection sleeve pipe 3.
