DETAILED DESCRIPTION

[0022] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Please refer to Figure 1 And Figure 2 The utility model provides a adjustable multipoint detection thermocouple, including flange plate 1, flange plate 1 passes through screw can be installed in the detection port of various equipment and is fixedly installed or temporarily fixed, flange plate 1 is evenly provided with through hole in circumference, and thermocouple 3 is inserted and installed in the through hole, and the distance between the detection end of thermocouple 3 and flange plate 1 is different, and thermocouple 3 is the existing equipment with temperature measurement function, and the length of the equipment can be adjusted along the through hole.

[0024] The center of flange plate 1 is fixedly installed with center pin 9, center pin 9 is rotatably installed with dial 7, the circumferential side of dial 7 is evenly provided with pawl 10, arc slot for abutting against thermocouple 3 is formed in pawl 10, torsion spring 11 is sleeved with center pin 9, and the both ends of torsion spring 11 are fixedly assembled with dial 7 and flange plate 1 respectively, dial 7 and pawl 10 have the force of counterclockwise rotation by torsion spring 11, so that the arc slot is abutted against thermocouple 3, the increased friction force can limit the movement of thermocouple 3 in the axial direction, and only when dial 7 and pawl 10 are rotated clockwise and the arc slot is separated from thermocouple 3, thermocouple 3 can be adjusted along the axial translation.

[0025] In addition, flange plate 1 is provided with limiting component 8 for fixing pawl 10, when limiting component 8 abuts against one of pawl 10, dial 7 is driven, the arc slot on each pawl 10 is abutted against thermocouple 3, thereby achieving the effect of tightening and fixing, and the displacement of detection point is avoided in the case of long-time non-use of the adjustment function.

[0026] In order to meet the use requirement of conventional temperature detection point, thermocouple 3 is at least 3 in circumferential distribution, that is, at least three positions are collected.

[0027] In order to improve the contact area of arc slot and arc plate 5, arc plate 5 is fixedly installed in the arc slot, the inner arc surface of arc plate 5 abuts against thermocouple 3, and the length of arc plate 5 is at least 3cm, so as to provide sufficient friction force, in addition, anti-skid lines can also be engraved on the inner arc surface of arc plate 5, further increasing the friction force when contacting.

[0028] In order to facilitate the operator to dial dial 7, a handle 6 is fixedly installed on the circumferential side of dial 7, which plays the role of saving labor.

[0029] For the convenience of the operator to know the adjustment distance when the thermocouple 3 is translated, the detection rod surface of the thermocouple 3 is provided with a scale strip 4, which is beneficial to reading and using.

[0030] Specifically, as shown in Figure 3 The limiting assembly 8 includes an internally threaded sleeve 82, a nut 83 and a screw 81. The internally threaded sleeve 82 is fixedly installed on the flange plate 1 through a support seat. The internally threaded sleeve 82 is located on one side of one of the pawls 10. The internally threaded sleeve 82 is screwed with the screw 81 for abutting against the pawl 10. The screw 81 is screwed with the nut 83. The nut 83 is located on one side of the internally threaded sleeve 82 close to the pawl 10. By adjusting the screwing depth of the screw 81 on the internally threaded sleeve 82, the swing amplitude of the pawl 10 can be limited. When locking is needed, the nut 83 on the screw 81 can be screwed to abut against the internally threaded sleeve 82 to increase the friction force between them so as to avoid loosening of the screw 81.

[0031] To meet the sealing performance requirement of the equipment, the following can be selected: a sealing sleeve 2 is installed inside the through hole. The thermocouple 3 is inserted into the sealing sleeve 2. The sealing performance is improved through the sealing sleeve 2. The overall length of the sealing sleeve 2 is at least 3 cm, so as to ensure sufficient sealing distance.

[0032] Specifically, the sealing sleeve 2 includes an end ring 21, a rubber cylinder 22 and a cylinder body 23. The cylinder body 23 is fixedly installed inside the through hole.

The end ring 21 for abutting against the rubber cylinder 22 is installed at both ends of the cylinder body 23 through screw connection. The space formed by the end ring 21 and the cylinder body 23 can extrude the rubber cylinder 22 in an interference-fitting manner, so as to seal the gap of the inserted assembly of the thermocouple 3. The thermocouple 3 can be axially adjusted by force. The sealing performance is improved without affecting the adjustment of the measurement distance.

[0033] The working principle of the embodiment is as follows:

[0034] First, the dial 7 is rotated clockwise by the handle 6, and the torsion spring 11 is twisted to store energy. At this time, the arc-shaped plate 5 is separated from the thermocouple 3. The insertion depth of each thermocouple 3 can be adjusted according to the scale strip 4 to adapt to the detection point positions in the equipment. After the dial 7 is released, the arc-shaped plate 5 is reset and fixedly abuts against the thermocouple 3. Then the thermocouple 3 is inserted into the equipment through the detection port. The flange plate 1 is installed on the detection port, so as to collect temperature at multiple points. The insertion depth of the thermocouple 3 can also be adjusted during temperature measurement to adjust the temperature measurement point.

[0035] For the working condition which is not adjusted frequently, the limit assembly 8 is used to top and lock the shifting claw 10, so as to avoid the movement of the thermocouple 3, and for the working condition which needs to change the position to detect the temperature temporarily, the limit assembly 8 is not used, so as to adjust the insertion depth of the thermocouple 3 frequently.
