Description

Technical Field

[0001] The present application relates to the field of thermocouples, and in particular to a hidden thermocouple contact rod triggering mechanism. Background Art

[0002] Thermocouples are commonly used temperature measuring elements in temperature measuring instruments. They directly measure temperature and convert the temperature signal into a thermoelectric potential signal, which is then converted into the temperature of the measured medium through an electrical instrument (secondary instrument). The appearance of various thermocouples often varies greatly depending on the needs, but their basic structure is roughly the same. They usually consist of a thermode, an insulating protective tube, and a junction box. They are usually used in conjunction with display instruments, recording instruments, and electronic regulators.

[0003] During the production process of aluminum coils, temperature detection is performed using thermocouples. To protect the thermocouples, a trigger mechanism is installed on the outside. However, the thermocouple trigger mechanism of existing thermocouple devices is exposed to the outside and consists of two flanges, two springs, and a screw. The structure is bloated and occupies a large space. The trigger mechanism often gets stuck in the guide tube, which increases the maintenance frequency and reduces production efficiency. Utility Model Content

[0004] In order to solve the problem that the existing thermocouple trigger mechanism is prone to failure during use and affects the normal detection of the thermocouple, the present application provides a hidden thermocouple contact rod trigger mechanism.

[0005] The present application provides a hidden thermocouple contact rod trigger mechanism that adopts the following technical solutions:

[0006] A hidden thermocouple touch rod trigger mechanism includes a mounting mechanism and a protective column installed on the mounting mechanism. The mounting mechanism includes a mounting seat, and two symmetrically arranged detection mechanisms are installed on the outer wall of the bottom of the mounting seat. A protective sleeve is fixedly connected to the outer wall of the bottom of the mounting seat. An annular groove is opened on the outer wall of the top of the protective column, and the protective sleeve is slidably connected to the inner wall of the annular groove.

[0007] By adopting the above technical solution, the detection mechanism is conveniently installed through the mounting seat in the installation mechanism, the setting of the detection mechanism is convenient for detecting the temperature of the aluminum coil by triggering the thermocouple, the setting of the protective sleeve is convenient for protecting the two detection mechanisms to prevent the exposed detection mechanism from being easily damaged, and the setting of the annular groove is convenient for the sliding installation of the protective sleeve.

[0008] The outer wall of the bottom of the mounting seat is provided with two mounting openings, and the inner walls of the two mounting openings are fixedly connected with thermocouple bodies.

[0009] By adopting the above technical solution, the thermocouple body can be conveniently installed through the mounting opening on the mounting seat, and the thermocouple body can conveniently and directly detect the temperature of the aluminum coil.

[0010] The outer wall of the top of the protective column is provided with two symmetrically arranged circular openings, and the two thermocouple bodies are respectively slidably connected to the inner walls of the two circular openings.

[0011] By adopting the above technical solution, the two circular openings on the protective column are opened to facilitate the passage of the two thermocouple bodies, thereby facilitating the protection of the two thermocouple bodies and preventing the thermocouple bodies and the aluminum coil from being damaged by friction.

[0012] The detection mechanism includes a detection component installed on a mounting seat and a mounting sleeve fixed on the top of the protective column, and two symmetrically arranged mounting components are installed on the outer wall of the mounting sleeve.

[0014] The detection assembly includes a detection tube fixedly connected to the mounting seat, and two mounting rods are fixedly connected to the inner walls on both sides of the detection tube, and the outer walls of the two mounting rods are slidably connected to the same driving seat, and the outer wall of the bottom of the driving seat is fixedly connected to a connecting column.

[0015] By adopting the above technical solution, two mounting rods are fixed in the detection tube. The setting of the mounting rods facilitates the sliding installation of the auxiliary drive seat and avoids the displacement of the drive seat. The setting of the connecting column facilitates the auxiliary installation in the mounting sleeve.

[0016] The outer wall of the connecting column is provided with two symmetrically arranged limit grooves, the outer walls of the two mounting rods are both sleeved with springs, the inner wall at the top of the detection tube is fixedly connected to a trigger switch, and the outer wall at the top of the driving seat is fixedly connected to a trigger seat matching the trigger switch.

[0017] By adopting the above technical solution, the protective column is fixed by the mounting sleeve and the connecting column. When the protective column moves, the driving seat is directly pushed through the connecting column to compress the spring, thereby causing the trigger seat to trigger the trigger switch, thereby starting the thermocouple body to detect the temperature of the aluminum coil.

[0018] The mounting assembly includes a fixing seat fixedly connected to the mounting sleeve, and a mounting cavity is opened inside the fixing seat, the inner wall of the mounting cavity is slidably connected to a T-shaped limit seat, and the limit seat slides through the mounting sleeve and is inserted into the limit groove.

[0019] By adopting the above technical solution, the setting of the installation cavity facilitates the sliding installation of the limit seat.

These detection components facilitate triggering the thermocouple to detect the temperature of the aluminum coil. A protective sleeve is provided between the mounting base and the protective column to conveniently protect the two detection components, thereby preventing damage to the exposed detection mechanism and improving its stability.

[0024] 2. This application sets a trigger switch in the detection component of the detection mechanism. When the protective column moves toward the mounting seat, it directly pushes the trigger seat on the connecting column to contact the trigger switch. When the trigger switch is triggered, the thermocouple directly detects the temperature of the aluminum coil. At the same time, the cooperation between the mounting sleeve and the mounting component facilitates the installation of the connecting column on the protective column.

[0032] The following is combined with Figures 1-6 This application is described in further detail.

[0033] The embodiment of the present application discloses a hidden thermocouple contact rod triggering mechanism.

[0034] Reference Figure 1-3 , a hidden thermocouple contact rod trigger mechanism, comprising a mounting mechanism 1 and a protective column 2 mounted on the mounting mechanism 1;

[0035] Reference Figure 1-3 The mounting mechanism 1 for assisting the installation of the thermocouple includes a mounting base 3, and two symmetrically arranged detection mechanisms 5 are installed on the outer wall of the bottom of the mounting base 3. A protective sleeve 4 is fixedly connected to the outer wall of the bottom of the mounting base 3. Two mounting openings are provided on the outer wall of the bottom of the mounting base 3, and the inner walls of the two mounting openings are fixedly connected to a thermocouple body 6. The thermocouple body 6 is convenient for directly detecting the temperature of the aluminum coil;

[0036] When in use, the detection mechanism 5 is conveniently installed through the mounting seat 3 in the mounting mechanism 1. The setting of the detection mechanism 5 is convenient for triggering the thermocouple to detect the temperature of the aluminum coil. The setting of the protective sleeve 4 is convenient for protecting the two detection mechanisms 5 to avoid the exposed detection mechanism 5 from being easily damaged. The thermocouple body 6 is conveniently installed through the mounting port on the mounting seat 3.

[0037] Reference Figure 1-3 The outer wall of the top of the protective column 2 for auxiliary protection of the thermocouple is provided with two symmetrically arranged circular openings 7, and the two thermocouple bodies 6 are respectively slidably connected to the inner walls of the two circular openings 7. The two circular openings 7 on the protective column 2 are opened to facilitate the passage of the two thermocouple bodies 6, thereby facilitating the protection of the two thermocouple bodies 6 and preventing the thermocouple bodies 6 from being damaged by friction with the aluminum coil.

[0038] Reference Figure 4-6The detection mechanism 5 of the auxiliary trigger thermocouple includes a detection component 8 installed on the mounting base 3 and a mounting sleeve 9 fixed on the top of the protective column 2. Two symmetrically arranged mounting components 10 are installed on the outer wall of the mounting sleeve 9. The two mounting components 10 on the mounting sleeve 9 cooperate to facilitate the fixation of the detection component 8, thereby facilitating the connection of the protective column 2 to the mounting base 3 through the detection component 8.

[0039] Reference Figure 4-5 The auxiliary thermocouple triggered detection assembly 8 includes a detection tube 11 fixedly connected to the mounting base 3, and two mounting rods 13 are fixedly connected to the inner walls of both sides of the detection tube 11, and the outer walls of the two mounting rods 13 are slidably connected to the same driving base 15, and the bottom outer wall of the driving base 15 is fixedly connected to a connecting column 17, and the outer wall of the connecting column 17 is provided with two symmetrically arranged limiting grooves 18, and the outer walls of the two mounting rods 13 are both sleeved with springs 14, the top inner wall of the detection tube 11 is fixedly connected to the trigger switch 12, and the top outer wall of the driving base 15 is fixedly connected to a trigger seat 16 that matches the trigger switch 12;

[0040] During use, two mounting rods 13 are fixed in the detection tube 11. The setting of the mounting rods 13 facilitates the sliding installation of the auxiliary drive seat 15 and prevents the drive seat 15 from being offset. The setting of the connecting column 17 facilitates the auxiliary installation in the mounting sleeve 9. The mounting sleeve 9 and the connecting column 17 are connected and fixed. When the protective column 2 moves, the drive seat 15 is directly pushed through the connecting column 17 to compress the spring 14, and then the trigger seat 16 triggers the trigger switch 12, thereby starting the thermocouple body 6 to perform temperature detection on the aluminum coil.

[0041] Reference Figure 4-6 The installation assembly 10 for installing the auxiliary connecting column 17 includes a fixing seat 19 fixedly connected to the mounting sleeve 9, and an installation cavity 20 is opened inside the fixing seat 19, and the inner wall of the mounting cavity 20 is slidably connected with a T-shaped limit seat 21, and the limit seat 21 slides through the mounting sleeve 9, and the limit seat 21 is inserted into the limit groove 18. A screw 22 is rotatably connected to the inner wall of one side of the mounting cavity 20, and a threaded groove is opened on the outer wall of one side of the limit seat 21. The screw 22 is screwed on the inner wall of the threaded groove. A circular groove is opened on the outer wall of one side of the fixing seat 19, and the inner wall of the circular groove is rotatably connected with a rotating part 23 connected to the screw 22.

[0042] During use, the setting of the installation cavity 20 facilitates the sliding installation of the limit seat 21. When the limit seat 21 slides out, it is directly inserted into the limit groove 18, so as to facilitate fixing the connecting column 17 in the installation sleeve 9. When the rotating part 23 rotates, it directly drives the screw 22 to rotate. When the screw 22 rotates, it directly drives the limit seat 21 to slide in the installation cavity 20, thereby facilitating the disassembly of the auxiliary protective column 2.

[0043] The implementation principle of a hidden thermocouple contact rod trigger mechanism in the embodiment of the present application is as follows: when in use, the mounting mechanism 1 is fixed to the mounting position of the thermocouple on the annealing furnace. At this time, the protective column 2 is inside the annealing furnace. When the temperature of the aluminum coil needs to be detected, the lifting structure directly drives the protective column 2 to rise and fall in the annealing furnace. When the protective column 2 contacts the aluminum coil, the mounting seat 3 continues to descend, and the protective column 2 directly pushes the driving seat 15 on the connecting column 17 to press the spring 14 on the mounting rod 13. When the spring 14 is compressed, the trigger seat 16 contacts the trigger switch 12. When the trigger switch 12 is triggered, the thermocouple body 6 is directly activated to detect the stability of the aluminum coil. When the protective column 2 needs to be disassembled, the rotating part 23 is directly rotated to drive the screw 22 to rotate. When the screw 22 rotates, it directly drives the limit seat 21 to slide in the mounting cavity 20. When the limit seat 21 is away from the limit groove 18, the protective column 2 can be removed from the mounting seat 3.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
