[0002] Thermocouples are commonly used temperature measuring elements in temperature measuring instruments. They directly measure temperature and convert temperature signals into thermoelectric potential signals, which are then converted into the temperature of the measured medium through electrical instruments (secondary instruments).

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model embodiment provides a quick release thermocouple, such as Figure 1-4 As shown, the quick-release thermocouple includes: a thermocouple body 1, a mounting block 2 is fixedly mounted on the thermocouple body 1, a plurality of cavities 5 are provided on the mounting block 2, and sliding holes are provided on the bottom inner walls of the plurality of cavities 5; a first annular plate 3 welded to the bottom of the mounting block 2, a plurality of through holes are provided on the first annular plate 3; a second annular plate 4 slidably mounted on the first annular plate 3, a plurality of slots are provided on the inner wall of the second annular plate 4; and a plurality of snap mechanisms assembled on the mounting block 2 for fixing the second annular plate 4.

[0023] It should be noted that conventional thermocouples are generally installed on equipment by flange mounting or threaded connection and are used to measure the temperature inside the equipment. This installation method is more complicated during the disassembly process and is not convenient for quick disassembly of the thermocouple, making it inconvenient to perform maintenance when a fault occurs, thereby reducing the convenience of disassembly of the thermocouple.

[0024] In the scheme, firstly, the thermocouple mainly includes a thermocouple body 1, a mounting block 2, a first annular plate 3, a second annular plate 4 and a plurality of snap-on mechanisms, each of which plays a unique role and together realizes the rapid release function of the thermocouple. The thermocouple body 1 is the core component of temperature measurement, which directly measures the temperature and converts it into a thermoelectromotive force signal. The mounting block 2 is used to fix the thermocouple body 1 and provides a platform for installing other components. On the mounting block 2, we designed a plurality of cavities 5, which can be used to accommodate the snap-on mechanisms. The first annular plate 3 is welded to the bottom of the mounting block 2, and a plurality of through holes are opened thereon, and the function of these through holes is to allow the snap-on mechanisms. Part of the structure of the mechanism passes through, thereby achieving fixation with the second annular plate 4. The second annular plate 4 is slidably sleeved on the first annular plate 3, and a plurality of slots are provided on its inner wall. These slots cooperate with the snap mechanism to achieve the functions of fixing and releasing. The design of the snap mechanism makes it possible to separate the second annular plate 4 from the first annular plate 3 by simply operating the snap mechanism when the thermocouple needs to be removed, thereby achieving rapid release of the thermocouple. Through the above structural design, the utility model realizes the rapid release function of the thermocouple body 1. This design not only simplifies the disassembly process of the thermocouple and improves the maintenance efficiency, but also ensures the stability of the thermocouple during installation.

[0025] In a further preferred embodiment of the utility model, the snap mechanism includes: a spring 6 fixedly mounted on the inner wall of one side of the cavity 5; a baffle 7 welded on the spring 6, a connecting rod 8 welded to the bottom of the baffle 7, and the connecting rod 8 is slidably connected to the inner wall of the sliding hole; a stopper 9 fixedly mounted on the bottom end of the connecting rod 8, an insert block 10 welded on the stopper 9, the insert block 10 is slidably connected to the through hole, and the insert block 10 is adapted to the slot; a pressing rod 11 slidably mounted on the mounting block 2, one end of the pressing rod 11 extends to the interior of the cavity 5, and one end of the pressing rod 11 is fixedly connected to the baffle 7; a pressing plate 12 welded on the pressing rod 11.

[0026] In this embodiment, the snap mechanism mainly includes a spring 6, a baffle 7, a connecting rod 8, a block 9, an insert 10, a pressing rod 11 and a pressing plate 12. These parts cooperate with each other to achieve rapid fixing and release of the thermocouple. First, the spring 6 is fixedly installed on the inner wall of one side of the cavity 5. The spring 6 has a certain elasticity and restoring force, which is used to provide power for the baffle 7 and the connecting rod 8 to reset. The baffle 7 is welded on the spring 6, and its bottom is connected to the connecting rod 8. The connecting rod 8 is slidably connected to the inner wall of the sliding hole, which allows the connecting rod 8 to slide freely in the sliding hole while ensuring the stability of the structure. The block 9 is fixedly installed on the bottom end of the connecting rod 8, and an insert 10 is welded on it. The insert 10 is slidably connected to the through hole and can be inserted into the slot to achieve fixation with the second annular plate 4. The matching design of the insert 10 and the slot ensures In order to ensure the firmness and stability of the fixation, the pressing rod 11 is slidably installed on the mounting block 2, one end of which extends to the interior of the cavity 5 and is fixedly connected to the baffle 7. The other end of the pressing rod 11 is welded with a pressing plate 12, which is convenient for the operator to perform the pressing operation. During use, when the thermocouple body 1 needs to be disassembled, it is only necessary to squeeze the pressing plate 12, and the pressing plate 12 drives the pressing rod 11 to slide, and the pressing rod 11 drives the baffle 7 to squeeze the spring 6, and the baffle 7 will drive the connecting rod 8 to move, and the connecting rod 8 will drive the stopper 9 to move, and the stopper 9 will drive the plug-in block 10 to disengage from the slot, and then the first annular plate 3 can be removed from the second annular plate 4 to achieve rapid release of the thermocouple body 1. The design of this snap mechanism is not only simple in structure and easy to operate, but also firmly fixed and quick to release, which greatly improves the disassembly efficiency of the thermocouple body 1 and reduces the difficulty of maintenance.

[0027] In a further preferred embodiment of the present invention, a plurality of limiting rods 13 are fixedly mounted on the inner walls of the cavities 5 , and the plurality of limiting rods 13 are slidably connected to the plurality of baffles 7 , respectively.

[0028] In this embodiment, firstly, the limit rod 13 guides and limits the baffle 7, ensuring that the baffle 7 always remains on the correct path and avoids deviation or shaking, which not only enhances the stability of the buckle mechanism, but also improves the accuracy of its operation.

[0029] In a further preferred embodiment of the present invention, a fixing plate 14 is fixedly mounted on the bottom of the second annular plate 4 , a plurality of threaded holes are formed on the fixing plate 14 , and the fixing plate 14 is configured to be circular.

[0030] In this embodiment, the fixing plate 14 is fixedly installed at the bottom of the second annular plate 4, and its shape is set to be circular.

[0032] In this embodiment, the soft pad 15 is made of rubber material, which has good elasticity and anti-slip performance. The introduction of the soft pad 15 enables the operator to feel a softer and more comfortable touch when pressing, thereby reducing the discomfort of the hand.

[0033] In a further preferred embodiment of the present invention, the plurality of sliding holes are all configured to be rectangular, and the plurality of springs 6, the plurality of baffles 7, the plurality of pressing rods 11 and the plurality of pressing plates 12 are all made of stainless steel.

[0034] In this embodiment, multiple sliding holes are all set to be rectangular. This rectangular design can better adapt to the sliding trajectory of the connecting rod 8 and ensure smooth movement along the sliding hole. The spring 6, baffle 7, pressing rod 11 and pressing plate 12 are all made of stainless steel. Stainless steel has excellent corrosion resistance and mechanical properties and can maintain stable performance in various harsh environments. The selection of stainless steel can not only ensure that these components are not easy to rust or deform during use, but also improve their strength and durability.

[0036] In this embodiment, firstly, the plurality of blocks 9 and the plurality of plug-in blocks 10 are designed to be rectangular. This rectangular design not only makes the blocks 9 and the plug-in blocks 10 more structurally stable and able to withstand greater forces, but also enhances their compatibility with the card slots. The rectangular shape can better match the card slots, reduce shaking and misalignment during insertion and removal, and thus improve the fixing effect of the snap mechanism. Secondly, the thickness of the fixing plate 14 is set to be no less than 5 mm. This design choice is intended to ensure that the fixing plate 14 has sufficient strength and rigidity to withstand various forces generated during installation and use. The thicker fixing plate 14 can better disperse and withstand these forces, and reduce deformation or damage caused by stress concentration.
