Description

Technical Field

[0001] This utility model relates to the field of signal conditioning equipment technology, specifically a signal conditioning device for fast-response thermocouples. Background Technology

[0002] Fast-response thermocouples are contact-type field instruments for measuring temperature. They are typically used in conjunction with corresponding secondary instruments or computer-based measurement systems to accurately measure the temperature of various media or objects during production processes. To improve the performance and measurement quality of the data acquisition system, fast-response thermocouples usually require signal conditioning devices. A signal conditioner is an input / output device that converts one electrical or mechanical signal (input signal) into another (output signal). In addition to isolation and interference suppression, signal conditioners also support signal conversion, signal distribution, and providing power to transmitters.

[0003] Existing signal conditioning devices for fast-response thermocouples, due to their arranged configuration, accumulate significant heat over extended periods. This heat not only affects normal operation but can also introduce errors into measurement results.

[0004] Existing signal conditioning devices for fast-response thermocouples typically connect the circuitry to the thermocouple, but this connection is merely a matter of mounting the circuitry on a plate, which affects its lifespan. Summary of the Invention

[0005] The purpose of this invention is to provide a signal conditioning device for fast-response thermocouples to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a signal conditioning device for a fast-response thermocouple, comprising a signal conditioning body; the signal conditioning body is evenly arranged above a mounting plate, and the mounting plate has evenly distributed limiting grooves on both sides, with a linkage support slidably connected inside the limiting grooves; the signal conditioning body has docking grooves on both sides, with a docking plate snapped into the docking groove; the docking plate is located on both sides of an expansion and contraction component; push rods are slidably connected to both sides of the expansion and contraction component, with one end of the push rod welded to one side of the docking plate; two vacuum cylinders are connected to the bottom of the expansion and contraction component by adhesive bonding; a magnetic block is slidably connected inside the expansion and contraction component, with a magnetic component on one side of the magnetic block; the magnetic component is movably connected inside the expansion and contraction component; the magnetic component can be easily flipped to push the magnetic block to move; a linkage frame is connected to the top of the linkage support by welding to support the wiring connecting the signal conditioning body.

[0007] A signal conditioning device for a fast-response thermocouple according to claim 1, characterized in that: a thermometer is connected above the vacuum cylinder, and a piston is slidably connected inside the vacuum cylinder for pushing the piston inside the vacuum cylinder by thermal expansion and contraction.

[0008] Preferably, a transmission rod is welded below the piston, and the transmission rod is movably connected to an expansion joint to increase the thrust.

[0009] Preferably, a rack is welded to the bottom end of the transmission rod, and the rack engages with one side of the magnetic block to facilitate the flipping of the magnetic block.

[0010] Preferably, a linkage rod is movably connected above the push rod, and a transmission rod is movably connected to the end of the linkage rod away from the push rod. One end of the transmission rod is movably connected to one side of the magnetic block to facilitate transmission.

[0011] Preferably, the linkage rod has a positioning shaft on its outside, the positioning shaft is movably connected through the linkage rod, and the positioning shaft is welded to the inside of the expansion joint, so that the linkage rod constitutes a force-saving lever.

[0012] Preferably, the linkage frame is internally connected to two pairs of support plates, one end of each support plate has a spring member, and the spring member is located inside the linkage frame.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] First, this utility model, through the installation of expansion and contraction components and their components, allows the docking plates on both sides of the expansion and contraction components to align with the docking grooves after the signal conditioning body is installed above the mounting plate. When the temperature rises, the liquid inside the thermometer expands, which in turn compresses the gas inside the vacuum cylinder. At this point, the piston, along with the transmission rod and rack, moves downwards, causing the magnetic block to flip via the gears on both sides of the magnetic block. This causes the magnetic block and the magnetic block to repel each other due to their similar polarities, moving the magnetic block away from the magnetic component. The transmission rod then causes the linkage rod to rotate around the positioning shaft, which in turn causes the push rod to move the docking plate away from the expansion and contraction components. Ultimately, during the use of the signal conditioning body, the spacing between the multiple arranged signal conditioning bodies increases, facilitating heat dissipation.

[0015] Secondly, this utility model, through the setting of the signal conditioning body and the expansion and contraction components and their respective objects, allows the fast-response thermocouple to fall from between the two receiving plates into the interior of the linkage frame when the connector of the signal conditioning body is connected to the fast-response thermocouple via the line. Then, the spring component will reset the receiving plate, and the linkage frame will slide inside the limiting groove through the linkage support to cooperate with the sliding of the signal conditioning body, ultimately supporting the connected line and thus protecting the line.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6A signal conditioning device for a fast-response thermocouple includes a signal conditioning body 10. The signal conditioning bodies 10 are evenly arranged above a mounting plate 12. Uniformly arranged limiting grooves 14 are formed on both sides of the mounting plate 12. A linkage support column 30 is slidably connected inside the limiting grooves 14. A docking groove 11 is formed on both sides of the signal conditioning body 10. A docking plate 293 is snapped into the inside of the docking groove 11. The docking plate 293 is located on both sides of an expansion member 20. Push rods are slidably connected to both sides of the expansion member 20. 21. One end of the push rod 21 is welded to one side of the docking plate 293. The bottom of the expansion and contraction part 20 is connected to two vacuum cylinders 290 by adhesive bonding. A magnetic block 25 is slidably connected inside the expansion and contraction part 20. A magnetic block 26 is on one side of the magnetic block 25. The magnetic block 26 is movably connected inside the expansion and contraction part 20. The magnetic block 26 can be easily flipped to push the magnetic block 25 to move. The top of the linkage support column 30 is connected to the linkage frame 31 by welding to support the circuit of the signal conditioning body 10.

[0025] Specifically, a thermometer 292 is connected to the top of the vacuum cylinder 290, and a piston 291 is slidably connected inside the vacuum cylinder 290, which is used to push the piston 291 inside the vacuum cylinder 290 through thermal expansion and contraction.

[0026] Through the above technical solution, the thermometer component 292 is a liquid thermometer such as an alcohol thermometer. It can expand the alcohol inside through thermal expansion and contraction, thereby pushing the piston 291 to move downward. Conversely, when the temperature drops, the alcohol inside will contract, thereby causing the piston 291 to return to its original position.

[0027] Specifically, a transmission rod 28 is welded below the piston 291, and the transmission rod 28 is movably connected to the expansion and contraction component 20 to increase the thrust.

[0028] Through the above technical solution, the piston 291 has a high degree of airtightness between the rubber ring and the interior of the vacuum cylinder 290, and the space above the piston 291 is in a vacuum state, so that the piston 291 is initially located at the top inside the vacuum cylinder 290.

[0029] Specifically, a rack 27 is welded to the bottom end of the transmission rod 28. The rack 27 engages with one side of the magnetic block 26 to facilitate the flipping of the magnetic block 26.

[0030] Through the above technical solution, the magnetic block 25 and the magnetic component 26 are two magnets, and in the initial state they are opposite and attract each other. When the magnetic component 26 is flipped, they become like surfaces and thus repel each other. The magnetic component 26 has convex shafts on both sides, which allows it to be movably connected inside the expansion member 20 and rotate around the convex shaft. The convex shaft has gears that mesh with the rack 27, allowing the magnetic component 26 to flip.

[0031] Specifically, a linkage rod 22 is movably connected above the push rod 21, and a transmission rod 24 is movably connected to the end of the linkage rod 22 away from the push rod 21. One end of the transmission rod 24 is movably connected to one side of the magnetic block 25 to facilitate transmission.

[0032] Through the above technical solution, the transmission rod 24 is used to facilitate the magnetic block 25 to push one end of the linkage rod 22 to move when sliding, so that the linkage rod 22 can rotate around the positioning shaft 23.

[0033] Specifically, the linkage 22 has a positioning shaft 23 on its outside. The positioning shaft 23 passes through and is movably connected to the linkage 22. The positioning shaft 23 is welded to the inside of the expansion and contraction component 20, so that the linkage 22 constitutes a force-saving lever.

[0034] Through the above technical solution, the expansion and contraction component 20 has cavities corresponding to the push rod 21, linkage rod 22, positioning shaft 23, transmission rod 24, magnetic block 25, magnetic block 26, rack 27 and transmission rod 28 to facilitate transmission. The positioning shaft 23 is movably connected to the end of the positioning shaft 23 near the push rod 21, thus forming a force-saving lever.

[0035] Specifically, the internal movable connection of the linkage frame 31 is provided with two pairs of support plates 32, and one end of the support plate 32 has a spring member 33, which is located inside the linkage frame 31.

[0036] With the above technical solution, the spring member 33 has extension rods at both ends to support the bottom of the receiving plate 32, while the other is used to fix it internally with the linkage frame 31, thereby facilitating the reset of the receiving plate 32.

[0037] In use, by using the expansion and contraction component 20 and its components, after the signal conditioning body 10 is installed above the mounting plate 12, the docking plates 293 on both sides of the expansion and contraction component 20 can be docked with the docking groove 11. Then, when the temperature rises, the liquid inside the thermometer component 292 expands, which in turn pushes the gas inside the vacuum cylinder 290 to compress it. At this time, the piston 291 will move downward with the transmission rod 28 and the rack 27, which will cause the magnetic block 26 to flip through the gears on both sides of the magnetic block 26, so that the magnetic block 26 and the magnetic block 25 are like-pairs and repel each other. At this time, the magnetic block 25 will move away from the magnetic block 26, and the linkage rod 22 will rotate around the positioning shaft 23 through the transmission rod 24, which will then... By moving the push rod 21 away from the docking plate 293 and the expansion member 20, the spacing between the multiple signal conditioning bodies 10 arranged above will increase during the use of the signal conditioning body 10, thus facilitating heat dissipation. Through the arrangement of the signal conditioning body 10, the expansion member 20, and their respective components, when the fast-response thermocouple is connected to the connector of the signal conditioning body 10 via a line, the line can fall from between the two receiving plates 32 into the interior of the linkage frame 31. Then, the spring member 33 will reset the receiving plate 32, and the linkage frame 31 is slidably connected to the interior of the limiting groove 14 via the linkage support 30 to cooperate with the sliding of the signal conditioning body 10, ultimately supporting the connected line and protecting it.
