The positioning seat 3 is arranged to rotate between the two adjusting seats 4 to switch the thermocouple angle, and the adjusting seat 4 is arranged to be movable on the fixing bracket 2 to adjust the position of the thermocouple; the fixing bracket 2 serves as the basic structure of the entire bracket and provides a stable supporting platform. The adjustment hole 201 thereon is designed to allow the adjusting seat 4 to be flexibly moved on the fixing bracket 2 to achieve precise adjustment of the thermocouple position, thereby enhancing the versatility and adaptability of the bracket, so that the bracket can adapt to thermocouple calibration furnaces of different sizes and positions.

[0029] The fixing frame 2 includes an adjustment hole 201 , which is opened at one side of the fixing frame 2 , and the adjustment seat 4 is connected in the adjustment hole 201 .

[0030] The adjusting seat 4 includes: a rotating seat 401, which passes through the adjusting seat 4, and one end of the rotating seat 401 is connected to the positioning seat 3; a nut 402, which is threadedly installed on the rotating seat 401; a gasket 403, which is installed on the rotating seat 401 and is arranged between the nut 402 and the fixing frame 2; the rotating seat 401 includes: a connecting groove 404, which is opened on the rotating seat 401; a limit block 405, which is installed in the connecting groove 404; a second elastic member 406, one end of which is connected to the connecting groove 404 and the other end is connected to the limit block 405, and the second elastic member 406 is used to provide the limit block 405 with a restoring force for the initial position; the adjusting seat 4 also includes: a plurality of limit grooves 407, which are opened in the inner ring of the adjusting seat 4 , distributed in a circular array, the limit block 405 is connected to the limit groove 407. By rotating the nut 402, the position of the adjusting seat 4 on the fixing frame 2 can be tightened, and the limit of the adjusting seat 4 can also be cancelled. The height of the adjusting seat 4 and the positioning seat 3 on the fixing frame 2 can be flexibly adjusted, and the use position of the thermocouple can be flexibly adjusted. When the limit block 405 is set in the limit groove 407, the position of the rotating seat 401 on the adjusting seat 4 can be limited. After pressing the limit block 405, the limit block 405 slides out of the limit groove 407 and completely enters the connecting groove 404, the positioning seat 3 can be rotated, and the positioning seat 3 drives the rotating seat 401 to rotate in the adjusting seat 4, which can drive the thermocouple to rotate and switch its fixed direction.

[0031] The positioning seat 3 includes: a plurality of clamping heads 301 connected to the positioning seat 3 and configured to simultaneously approach or move away from the center of the positioning seat 3, the clamping heads 301 being used to clamp the thermocouple; a plurality of grooves 303 opened in the inner circle of the positioning seat 3 and distributed in a circular array, the clamping heads 301 being connected in the grooves 303; a first elastic member 302, one end of which is connected to the side wall of the groove 303 and the other end is connected to the clamping head 301, the first elastic member 302 being used to provide the clamping head 301 with a restoring force for the initial position, the clamping head 301 being able to simultaneously approach or move away from the center of the positioning seat 3 through the elastic force of the first elastic member 302, thereby achieving a stable clamping of the thermocouple, ensuring the stability of the thermocouple during the calibration process, and reducing the measurement error caused by vibration or displacement, the circular array distribution of the grooves 303 and the restoring force design of the first elastic member 302 make the adjustment of the clamping head 301 more flexible and convenient.

[0032] The base 1 and the two fixing frames 2 are both installed on the base 1; the projection shape of the positioning seat 3 is a circular ring, and the projection shape of the adjustment seat 4 is a circular ring.

[0033] During use, according to the specific size of the thermocouple calibration furnace and the placement requirements of the thermocouple, the position of the adjustment seat 4 on the fixing frame 2 is moved to make the height between the two adjustment seats 4 appropriate, and the nut 402 and the gasket 403 are combined. The adjustment seat 4 can be fastened to the fixing frame 2 by rotating the nuts 402 on the two fixing frames 2, and the thermocouple is inserted into the positioning seat 3. The thermocouple squeezes the clamping head 301, and the elastic force of the first elastic member 302 makes the clamping head 301 approach the center of the positioning seat 3 at the same time, firmly clamping the thermocouple. The circumferential array distribution of the clamping head 301 and the restoring force design of the first elastic member 302 ensure the uniformity and flexibility of the clamping. If necessary To switch the fixed direction of the thermocouple, first press the limit block 405 to make it slide out of the limit groove 407 and completely enter the connecting groove 404. At this time, the positioning seat 3 can be rotated, and the positioning seat 3 drives the rotating seat 401 to rotate in the adjusting seat 4, driving the thermocouple to rotate to the required angle. After rotating to the appropriate position, release the limit block 405 and make it re-engage in the limit groove 407 to fix the current angle of the positioning seat 3 and the thermocouple. After the thermocouple is firmly clamped and adjusted to the appropriate angle, start the calibration process. Due to the firm support of the fixed bracket and the precise clamping of the thermocouple, the calibration process can reduce the measurement error caused by vibration or displacement, and improve the accuracy and reliability of the calibration.

[0034] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0035] By designing an adjustable adjustment seat 4 and a rotatable positioning seat 3, the adaptability and adjustability of the fixed bracket are improved. The adjustment seat 4 can be flexibly moved on the fixed bracket 2 to adapt to thermocouple calibration furnaces of different sizes and positions; the positioning seat 3 can be rotated between the two adjustment seats 4 to achieve the switching of the thermocouple angle to meet the requirements of different detection port directions, so that the fixed bracket can easily cope with thermocouple calibration furnaces of various models and specifications, thereby improving the versatility and flexibility of the equipment.

[0036] The clamping head 301 on the positioning seat 3 can firmly clamp the thermocouple through the elastic force of the first elastic member 302, thereby ensuring its stability during the calibration process, reducing measurement errors caused by vibration or displacement, and improving the accuracy and reliability of calibration.
