Description

Technical Field

[0001] This application relates to the field of temperature sensor technology, and in particular to a thermocouple clamping device. Background Technology

[0002] In related technologies, thermocouples are required inside boilers, furnaces, kilns, incinerators, and other similar equipment for temperature monitoring. These thermocouples are typically secured with screws, a method with several drawbacks. For example, when a thermocouple expands due to heat, the resistance between the screw and the thermocouple increases. This means that removing the thermocouple inevitably damages it, compromising its integrity and accuracy during production and potentially rendering it unusable. Furthermore, the cumbersome installation and removal of screws leads to time-consuming and inefficient thermocouple replacements, severely impacting production. Finally, the fixed position of the thermocouple within the furnace limits its temperature measurement range. To monitor temperatures at different locations within the furnace, the thermocouple must first be removed, then moved to the appropriate position and secured with screws – a very inconvenient process. Utility Model Content

[0003] This application provides a thermocouple clamping device, which aims to solve the problems of limited temperature measurement range, low disassembly and assembly efficiency, and easy damage during disassembly and assembly of in-furnace thermocouples in related technologies.

[0004] To address the aforementioned drawbacks in related technologies, this application provides a thermocouple clamping device. This device includes a frame, a crossbeam, a first screw, and a second screw. The crossbeam is slidably mounted on the frame, with its sliding direction perpendicular to its own axis. A receiving hole is formed on the outer wall of the crossbeam, located in the middle of the crossbeam. A first screw hole and a second screw hole, respectively, are formed at both ends of the crossbeam, connecting to the receiving hole. One end of the first screw is inserted into the first screw hole and threadedly engaged with it, and one end of the second screw is inserted into the second screw hole and threadedly engaged with it. Specifically, the receiving hole is used to accommodate the thermocouple to be fixed; the first screw and the second screw are used to move towards each other under external force until they enter the receiving hole and abut against the thermocouple, thereby fixing the thermocouple in the receiving hole.

[0005] In some implementations, the end of the first screw located within the first screw hole has a first slot for abutting against the thermocouple. Preferably, the first slot is triangular in shape.

[0006] In some implementations, the second screw includes a screw body and a fixing rod. One end of the screw body is inserted into and threaded into a second screw hole. The fixing rod is located inside the second screw hole and is connected to the screw body at one end. The other end of the fixing rod has a second slot for abutting a thermocouple. Preferably, the second slot is arc-shaped. As one or more implementations, the second screw also includes a spring, with its two ends connected to the screw body and the fixing rod, respectively.

[0007] In some implementation schemes, the frame includes a crossbar and two opposing and spaced-apart vertical bars. The extension direction of the crossbar is the same as the axis of the beam, and the extension direction of the vertical bars is perpendicular to the axis of the beam. The two ends of the crossbar are respectively connected to one end of the two vertical bars, and the two ends of the beam are respectively slidably mounted on the two vertical bars.

[0008] In some implementations, the crossbar has two opposite and spaced-apart mounting holes.

[0009] In some implementations, each of the two vertical rods is provided with a first sliding structure, and the crossbeam is provided with two opposing and spaced-apart second sliding structures. The two second sliding structures are used to cooperate with the two first sliding structures respectively, so that the two ends of the crossbeam are slidably connected to the two vertical rods respectively. As one or more of these implementations, the first sliding structure includes a slide rail, and the second sliding structure is a groove that cooperates with the slide rail; or, the first sliding structure is a slide path, and the second sliding structure includes a slider that cooperates with the slide path.

[0010] The thermocouple clamping device provided in this application consists of a frame, a crossbeam, a first screw, and a second screw. The crossbeam is slidably mounted on the frame and its sliding direction is perpendicular to its own axis. A receiving hole is provided in the middle of the outer side wall of the crossbeam. A first screw hole and a second screw hole connecting the receiving hole are respectively provided at both ends of the crossbeam. One end of the first screw is inserted into the first screw hole and is threaded into the first screw hole. One end of the second screw is inserted into the second screw hole and is threaded into the second screw hole. In practical applications, the thermocouple can be placed in the receiving hole on the crossbeam. Then, by rotating the two screws (i.e., the first screw and the second screw), the two screws are moved towards each other until they enter the receiving hole and abut against the thermocouple. The thermocouple is then fixed in the receiving hole by the clamping of the two screws. Finally, the frame is fixed in the furnace body (such as a boiler, furnace, kiln, incinerator, etc.), and the temperature inside the furnace can be monitored by the thermocouple. In addition, the position of the thermocouple can be adjusted by sliding the crossbeam, so that the thermocouple can monitor the temperature at different locations inside the furnace. Therefore, compared to the traditional method of using screws to fix the thermocouple, this application uses two screws to clamp the thermocouple, which not only simplifies the thermocouple assembly and disassembly process and reduces the time spent replacing the thermocouple, but also avoids damage to the thermocouple by the screws during disassembly after the thermocouple expands due to heat. This ensures the integrity and accuracy of the thermocouple in production operations. Furthermore, the position of the thermocouple in the furnace is adjustable, which expands the temperature measurement range of the thermocouple in the furnace, thus eliminating the need to disassemble the thermocouple to adjust its position as in the traditional method.

Detailed Implementation

[0015] In related technologies, thermocouples are typically fixed with screws, which has the following drawbacks: When a thermocouple expands due to heat, the resistance between the screw and the thermocouple increases. Therefore, when disassembling the thermocouple, the screw will inevitably damage it, affecting the integrity and accuracy of the thermocouple during production. It may even cause the thermocouple to completely lose its temperature-measuring capability and become scrap. The screw installation and removal are cumbersome, resulting in excessively long replacement times and low efficiency, severely impacting production progress. The fixed position of the thermocouple limits its temperature measurement range. Therefore, when monitoring temperatures at different locations, the thermocouple must first be removed, then moved to the corresponding position and fixed with screws, which is very troublesome. In view of this, this application proposes a thermocouple clamping device in the embodiments below to solve the above-mentioned drawbacks of the related technologies.

[0016] To make the objectives, technical solutions, and advantages of this application more apparent and understandable, this application will be clearly and completely described below in conjunction with its embodiments and corresponding drawings. Throughout, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. It should be understood that the embodiments of this application described below are only for explaining this application and are not intended to limit this application. That is, all other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0017] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the thermocouple clamping device. Figure 2 yes Figure 1A partial enlarged view at point A. This embodiment provides a thermocouple clamping device, which includes a frame 1, a crossbeam 2, a first screw 3, and a second screw 4. The crossbeam 2 is slidably mounted on the frame 1, and the sliding direction of the crossbeam 2 is perpendicular to its own axis. An inwardly recessed receiving hole 21 is provided on the outer side wall of the crossbeam 2, and the receiving hole 21 is located in the middle of the crossbeam 2. A first screw hole 22 and a second screw hole 23 that are inwardly recessed and connected to the receiving hole 21 are respectively provided on the end faces of opposite ends of the crossbeam 2. One end of the first screw 3 is inserted into the first screw hole 22 and threadedly engaged with the first screw hole 22, and one end of the second screw 4 is inserted into the second screw hole 23 and threadedly engaged with the second screw hole 23.

[0018] In this embodiment, the receiving hole 21 is used to accommodate the thermocouple to be fixed; the first screw 3 and the second screw 4 are used to move towards each other under the action of external force until they enter the receiving hole 21 and abut against the thermocouple, thereby fixing the thermocouple in the receiving hole 21. That is to say, in practical applications, the thermocouple can be placed in the receiving hole 21 on the crossbeam 2, and then by rotating the two screws (i.e., the first screw 3 and the second screw 4), the two screws are moved towards each other until they enter the receiving hole 21 and abut against the thermocouple, so that the thermocouple is fixed in the receiving hole 21 by the clamping of the two screws. Finally, the frame 1 is fixed in the furnace body, and the temperature inside the furnace body can be monitored by the thermocouple to ensure the normal operation of the furnace body; in addition, the position of the thermocouple can be adjusted by sliding the crossbeam 2 on the frame 1, so that the thermocouple can monitor the temperature at different positions inside the furnace body. It should be noted that the furnace body in this embodiment can be any furnace body commonly used in the art that has temperature monitoring requirements, such as boilers, furnaces, kilns, incinerators, etc. The specific choice can be made according to actual needs, and this embodiment does not limit it to a single type.

[0019] In this embodiment, a rotating handle 6 is provided at the end of the first screw 3 located outside the first screw hole 22 and at the end of the second screw 4 located outside the second screw hole 23. The user can hold the rotating handle 6 to rotate the first screw 3 and the second screw 4, causing the first screw 3 and the second screw 4 to move towards each other or away from each other, thereby clamping or releasing the thermocouple in the receiving hole 21. That is to say, the main function of the rotating handle 6 in this embodiment is to facilitate the user's rotation of the first screw 3 and the second screw 4.

[0020] As can be seen from the above, compared with the traditional solution of using screws to fix the thermocouple, this embodiment uses two screws to clamp the thermocouple, which not only simplifies the thermocouple assembly and disassembly process and reduces the time spent replacing the thermocouple, but also avoids damage to the thermocouple by the screws during disassembly after the thermocouple expands due to heat. This ensures the integrity and accuracy of the thermocouple in production operations. Furthermore, the position of the thermocouple in the furnace is adjustable, which expands the temperature measurement range of the thermocouple in the furnace, thus eliminating the need to disassemble the thermocouple to adjust its position as in the traditional solution.

[0021] In some embodiments, please refer to Figure 1 and Figure 2 The first screw 3 has an inwardly recessed first groove 31 on one end face of the screw 3 located inside the first screw hole 22. The second screw 4 includes a screw body 41 and a fixing rod 42. One end of the screw body 41 is inserted into the second screw hole 23 and threadedly engaged with it. The fixing rod 42 is located inside the second screw hole 23 and one end is connected to the screw body 41. The other end face of the fixing rod 42 has an inwardly recessed second groove 421. It can be understood that during the process of fixing the thermocouple in the receiving hole 21, when the first screw 3 and the second screw 4 clamp the thermocouple in the receiving hole 21, the opposite sides of the thermocouple will be located inside the first groove 31 and the second groove 421 respectively, and will also abut against the groove walls of the first groove 31 and the second groove 421 respectively. This confines the thermocouple within the receiving hole 21, thereby achieving the fixation of the thermocouple. Preferably, the first slot 31 is triangular in shape and the second slot 421 is arc-shaped. Typically, the thermocouple is circular in shape. Therefore, in order to ensure that the opposite sides of the thermocouple can be surrounded by the first slot 31 and the second slot 421 respectively, the dimensions of the first slot 31 and the second slot 421 must be larger than the arc of the thermocouple.

[0022] In at least one embodiment, the second screw 4 includes a screw body 41 and a fixing rod 42, as well as a spring 43. The spring 43 is located inside the second screw hole 23. The screw body 41 and the fixing rod 42 are connected by the spring 43, that is, the two opposite ends of the spring 43 are connected to the screw body 41 and the fixing rod 42, respectively. It can be understood that during the process of fixing the thermocouple in the receiving hole 21, after the first screw 3 and the second screw 4 clamp the thermocouple in the receiving hole 21, the spring 43 is compressed. The elastic force provided by the spring 43 will assist the fixing rod 42 in pressing the thermocouple into the triangular first slot 31, thereby achieving the fixation of the thermocouple and optimizing the fixation effect of the thermocouple.

[0023] In some embodiments, please refer to Figure 1 and Figure 2The frame 1 includes a crossbar 11 and two opposing and spaced-apart vertical bars 12. The extension direction of the crossbar 11 is the same as the axial direction of the crossbeam 2, and the extension directions of the two vertical bars 12 are both perpendicular to the axial direction of the crossbeam 2, i.e., the two vertical bars 12 are parallel. The opposite ends of the crossbar 11 are respectively connected to one end of the two vertical bars 12, and the opposite ends of the crossbeam 2 are slidably mounted on the two vertical bars 12. Specifically, each of the two vertical bars 12 is provided with a first sliding structure 5, and the crossbeam 2 is provided with two opposing and spaced-apart second sliding structures (not shown in the figure). The two second sliding structures can respectively cooperate with the two first sliding structures 5, so that the opposite ends of the crossbeam 2 are slidably connected to the two vertical bars 12, thereby giving the crossbeam 2 the ability to slide back and forth along the axial direction of the two vertical bars 12.

[0024] As at least one embodiment, the first sliding structure 5 includes a slide rail (not shown) disposed on the vertical rod 12, and the second sliding structure is a slide groove (not shown) formed on the crossbeam 2 and cooperating with the slide rail. Both the slide rail and the slide groove extend along the axial direction of the vertical rod 12. In practical applications, the crossbeam 2 is slidably engaged on the two slide rails through the two slide grooves, thereby realizing the sliding cooperation between the crossbeam 2 and the two vertical rods 12.

[0025] Of course, the first sliding structure 5 and the second sliding structure are not limited to this. In other embodiments, the first sliding structure 5 and the second sliding structure can also adopt other structures commonly used in the art to achieve sliding fit. For example, the first sliding structure 5 is a slide rail (not shown) opened on the vertical rod 12, and the second sliding structure includes a slider (not shown) disposed on the crossbeam 2 and cooperating with the slide rail. The slide rail extends along the axial direction of the vertical rod 12. In practical applications, the two sliders on the crossbeam 2 are slidably disposed in the two slide rails, so that the sliding fit between the crossbeam 2 and the two vertical rods 12 can be realized.

[0026] In at least one embodiment, the crossbar 11 has two opposing and spaced-apart mounting holes 111. When fixing the frame 1 to the furnace body, fasteners such as bolts can be passed through the mounting holes 111 and placed on the inner wall of the furnace body, thus installing the crossbar 11 into the furnace body, i.e., installing the frame 1 into the furnace body. Furthermore, it should be noted that the mounting holes 111 are not limited to being on the crossbar 11, nor are their number limited to two. In other embodiments, the number of mounting holes 111 can be three or more. In addition to the crossbar 11, mounting holes 111 can also be provided on the two vertical bars 12. The specific design can be based on actual needs, and this application does not impose a unique limitation. Preferably, there are two mounting holes 111, located at the junctions of the two ends of the crossbar 11 and the two vertical bars 12.

[0027] The above embodiments are merely preferred implementations of this application and are not the only limitations on the thermocouple clamping device. Those skilled in the art can make flexible settings based on the above embodiments and according to actual application scenarios. It is understood that through the implementation of the above embodiments of this application, the frame 1, crossbeam 2, first screw 3, and second screw 4 together constitute a thermocouple clamping device. The crossbeam 2 slides on the frame 1 with its sliding direction perpendicular to its own axis. A receiving hole 21 located in the middle is opened on the outer wall of the crossbeam 2. A first screw hole 22 and a second screw hole 23 communicating with the receiving hole 21 are respectively opened at both ends of the crossbeam 2. One end of the first screw 3 is inserted into the first screw hole 22 and threadedly engaged with it. One end of the second screw 4 is inserted into the second screw hole 23 and threadedly engaged with it. In practical applications, the thermocouple can be placed in the receiving hole 21 on the crossbeam 2. Then, by rotating the two screws (i.e., the first screw 3 and the second screw 4), the two screws move towards each other until they enter the receiving hole 21 and abut against the thermocouple. The thermocouple is then fixed in the receiving hole 21 by the clamping of the two screws. Finally, the frame 1 is installed in the furnace body, and the temperature inside the furnace body can be monitored by the thermocouple. In addition, the position of the thermocouple can be adjusted by sliding the crossbeam 2, so that the thermocouple can monitor the temperature at different locations inside the furnace body. Therefore, compared to the traditional method of using screws to fix the thermocouple, this application uses two screws to clamp the thermocouple, which not only simplifies the thermocouple assembly and disassembly process and reduces the time spent replacing the thermocouple, but also avoids damage to the thermocouple by the screws during disassembly after the thermocouple expands due to heat. This ensures the integrity and accuracy of the thermocouple in production operations. Furthermore, the position of the thermocouple in the furnace is adjustable, which expands the temperature measurement range of the thermocouple in the furnace, thus eliminating the need to disassemble the thermocouple to adjust its position as in the traditional method.
