Description

Technical Field

[0001] This utility model is a thermocouple, belonging to the field of thermocouples. Background Technology

[0002] A thermocouple is a temperature sensor composed of two different metal conductors that convert temperature changes into potential changes. The working principle of a thermocouple is based on the Seebeck effect. When there is a temperature difference at the junction of two different metals, voltage and current are generated in the circuit. Thermocouples do not require an external power supply, are easy to use, and are commonly used to measure the temperature of gases or liquids in furnaces and pipes, as well as the surface temperature of solids. The most common way to install thermocouples is through flanges. Flange mounting is suitable for most containers and allows for the disassembly and replacement of the thermocouple.

[0003] However, most existing thermocouples require multiple bolts or screws for flange installation, and external auxiliary tools are needed to install and fix the bolts, which makes the overall installation process more complicated and reduces the installation efficiency of thermocouples. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a thermocouple to solve the problems mentioned in the background art. This utility model enables the installation rod to be quickly and easily connected to the installation port, making the installation process simple and convenient and improving the installation efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a thermocouple, including a sensor body, a mounting rod provided on one side of the sensor body, a sensing rod fixedly connected to one end of the mounting rod, a first thread provided on the outer wall of the mounting rod, a nut threaded onto the outer wall of the first thread, and a mounting component provided on the outer wall of the mounting rod.

[0006] The mounting component includes a groove formed on the outer wall of the mounting rod, a rotating rod fixedly connected to the inner wall of the groove, a limiting plate rotatably sleeved on the outer wall of the rotating rod, a first spring fixedly connected to the outer wall of the limiting plate, one end of the first spring being fixedly connected to the inner side wall of the groove, and a limiting component provided inside the mounting rod.

[0007] Furthermore, the limiting component includes a channel and a through groove formed on the mounting rod, wherein a lifting block is slidably sleeved on the inner wall of the channel, the top of the lifting block is inclined, and a lifting plate is fixedly connected to the bottom of the lifting block.

[0008] Furthermore, a lifting column is fixedly connected to the top of the lifting plate, a third spring is fixedly connected to the inner bottom wall of the lifting column, and a locking rod is fixedly connected to the top of the third spring.

[0009] Furthermore, the locking rod is slidably sleeved with the lifting column, the locking rod is slidably sleeved with the through groove, and the mounting rod is provided with a connecting component inside.

[0010] Furthermore, the connecting component includes a second spring and a telescopic rod, one end of the second spring being fixedly connected to one side of the lifting plate, and one end of the telescopic rod being fixedly connected to one side of the lifting plate.

[0011] Furthermore, the outer wall of the mounting rod is provided with a second thread, and a threaded tube is threaded onto the outer wall of the second thread.

[0012] The beneficial effects of this utility model are:

[0013] 1. Insert the mounting rod through the mounting opening. The limiting plate will rotate into the groove. After the limiting plate enters the container, it will be reset by the first spring. Then, pull the mounting rod outward so that the limiting plate is only against the inner wall of the container. Rotate the nut, and the nut will move on the first thread. Then, the nut will move towards the outer wall of the container, which will cause the sealing element on one side of the nut to only be against the outer wall of the container. The sealing element will then seal the mounting opening, realizing the quick and easy installation of the mounting rod on the mounting opening. The installation process of this device is simple and convenient, improving installation efficiency.

[0014] 2. There are multiple locking rods. The locking rods located inside the nut will be resisted by the inner wall of the nut and move into the interior of the lifting column. Thus, the locking rods located inside the nut will not be affected. The locking rods located on one side of the nut will limit the nut, preventing the nut from turning over. This improves the stability of the device installation and further meets the usage requirements of the device. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-5 This utility model provides a technical solution: a thermocouple, including a sensor body 1, a mounting rod 2 on one side of the sensor body 1, a sensing rod 3 fixedly connected to one end of the mounting rod 2, a first thread 8 on the outer wall of the mounting rod 2, a nut 9 threaded onto the outer wall of the first thread 8, rotating the nut 9 will cause the nut 9 to move on the first thread 8, a rubber seal is provided on one side of the nut 9, the rubber seal can play a sealing role, and an installation component is provided on the outer wall of the mounting rod 2.

[0024] The mounting components include a groove 4 formed on the outer wall of the mounting rod 2, a rotating rod 5 fixedly connected to the inner wall of the groove 4, a limiting plate 6 rotatably sleeved on the outer wall of the rotating rod 5, and a first spring 7 fixedly connected to the outer wall of the limiting plate 6. One end of the first spring 7 is fixedly connected to the inner side wall of the groove 4. When the mounting rod 2 is passed through the mounting opening, the limiting plate 6 will rotate into the inside of the groove 4. After the limiting plate 6 enters the container, it will be reset by the first spring 7. Then the mounting rod 2 is pulled out of the container so that the limiting plate 6 will only fit against the inner wall of the container. The mounting rod 2 is provided with a limiting component inside.

[0025] The limiting component includes a channel 10 and a through groove 18 opened on the mounting rod 2. A lifting block 11 is slidably sleeved on the inner wall of the channel 10. The top of the lifting block 11 is inclined, and a lifting plate 12 is fixedly connected to the bottom of the lifting block 11. When the outside of the lifting block 11 is subjected to a large force, it will enter the interior of the mounting rod 2 through the channel 10, thereby driving the lifting plate 12 to move.

[0026] A lifting column 15 is fixedly connected to the top of the lifting plate 12. A third spring 16 is fixedly connected to the inner bottom wall of the lifting column 15. A locking rod 17 is fixedly connected to the top of the third spring 16. There are multiple locking rods 17. The locking rod 17 located on the side of the nut 9 will limit the nut 9, so that the nut 9 will not reverse. When the lifting plate 12 moves, it will drive the lifting column 15 and the locking rod 17 to move together. Then the locking rod 17 will enter the interior of the mounting rod 2 through the through groove 18, and then the locking rod 17 will no longer limit the nut 9.

[0027] The locking rod 17 is slidably sleeved with the lifting column 15 and the through groove 18. The mounting rod 2 has a connecting component inside. The locking rod 17 located inside the nut 9 will be resisted by the inner wall of the nut 9 and move into the lifting column 15. Thus, the locking rod 17 located outside the nut 9 will limit the nut 9, and the locking rod 17 located inside the nut 9 will not be affected.

[0028] The connecting components include a second spring 13 and a telescopic rod 14. One end of the second spring 13 is fixedly connected to one side of the lifting plate 12, and one end of the telescopic rod 14 is fixedly connected to one side of the lifting plate 12. There are two limiting components, both of which are mounted on the mounting rod 2 and are arranged in a mirror image. The two lifting plates 12 in the two limiting components are connected together through the second spring 13 and the telescopic rod 14. After the two lifting plates 12 move in opposite directions, they can be reset by the elastic force of the second spring 13.

[0029] The outer wall of the mounting rod 2 is provided with a second thread 20, and a screw tube 19 is threaded onto the outer wall of the second thread 20. When the screw tube 19 is rotated, the screw tube 19 will rotate on the second thread 20. The screw tube 19 will pass through the lifting block 11. The lifting block 11 will move into the mounting rod 2 through the channel 10 due to the resistance of the inner wall of the screw tube 19. This will drive the lifting plate 12 and the locking rod 17 to move into the mounting rod 2. As a result, the locking rod 17 will not limit the nut 9, so the nut 9 can be rotated at will for position adjustment.

[0030] Working principle: First, the mounting rod 2 is inserted through the mounting opening, and the limiting plate 6 will rotate into the inside of the groove 4. After the limiting plate 6 enters the container, it will be reset by the first spring 7. Then, the mounting rod 2 is pulled out of the container so that the limiting plate 6 will only fit against the inner wall of the container.

[0031] Secondly, by rotating the nut 9, the nut 9 will move on the first thread 8, and then the nut 9 will move towards the outer wall of the container, which will cause the seal on one side of the nut 9 to fit only against the outer wall of the container, and then the seal will seal the installation port, so that the installation rod 2 can be quickly sleeved and installed on the installation port.

[0032] Finally, there are multiple locking rods 17. The locking rod 17 located inside the nut 9 will be resisted by the inner wall of the nut 9 and will move into the interior of the lifting column 15. Thus, the locking rod 17 located inside the nut 9 will not be affected. The locking rod 17 located on one side of the nut 9 will limit the nut 9, and the nut 9 will not reverse.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
