Description

Technical Field

[0001] This utility model belongs to the field of thermocouple technology, and in particular relates to a pluggable thermocouple structure for powder metallurgy sintering furnaces. Background Technology

[0002] In the prior art, a search revealed a Chinese patent entitled "A Plug-in High-Temperature Fast-Response Thermocouple," with publication number "CN221350316U." This patent primarily utilizes a plug-and-play detachable connection between a waterproof plug and a waterproof socket. For the easily damaged high-temperature fast-response thermocouple, the plug and socket can be separated when damaged, without affecting the connection of the other end of the thermocouple extension wire to the device; only the damaged armored thermocouple portion needs to be replaced. This provides a simpler disassembly method, improves the replacement of easily damaged parts, and saves costs.

[0003] However, the above-mentioned device lacks a limiting structure when connecting the plug and socket. When the operator pulls the connecting wire or moves the plug while using the thermocouple, the plug may easily become detached from the socket, resulting in poor contact. This situation will affect the signal transmission of the thermocouple, leading to inaccurate measurement data. Utility Model Content

[0004] The purpose of this invention is to provide a pluggable thermocouple structure for powder metallurgy sintering furnaces. By setting up an installation mechanism, the lack of a limiting structure when connecting the plug and socket in the above-mentioned device is solved. When the operator pulls the connecting wire or moves the plug when using the thermocouple, the plug and socket are easily separated, resulting in poor contact. This situation will affect the signal transmission of the thermocouple and thus lead to inaccurate measurement data.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

Two insert sleeves are fixedly connected to the front side of the inner wall of the connecting shell, with the front sides of both insert sleeves extending to the outside of the connecting shell. The outer walls of both plug shells are slidably connected to the inner walls of the two insert sleeves. Two fixing rods are fixedly connected to the inner wall of the mounting shell, with sliding shells slidably connected to the outer walls of both fixing rods. The outer walls of both sliding shells are slidably connected to the inner walls of both the mounting shell and the connecting shell. Push shells are fixedly connected to the left side of the left sliding shell and the right side of the right sliding shell, with the outer walls of both push shells slidably connected to the outer walls of the two fixing rods.

[0007] Furthermore, both of the push shells slide to the outside of the mounting shell. Several insert rods are fixedly connected to the left side of the left slide shell and the right side of the right slide shell. The outer walls of the insert rods are slidably connected to the inner wall of the connecting shell. Springs are wound around the outer walls of the two fixed rods. One end of each spring is fixedly connected to the inner wall of the two mounting shells, and the other end of each spring is fixedly connected to the outer wall of the two slide shells.

[0008] Furthermore, the mounting housing is provided with a connecting mechanism inside, the connecting mechanism including a connecting line that is slidably connected to the inner wall of the mounting housing and the connecting housing.

[0009] Furthermore, both connecting lines extend to the outside of the mounting shell and the connecting shell, with the other end of the connecting line on the front side fixedly connected to the main body.

[0010] Furthermore, a first clamping shell is fixedly connected to the bottom of the inner wall of the mounting shell and the bottom of the inner wall of the connecting shell, and a plurality of connecting rods are fixedly connected to the inner wall of the mounting shell and the inner wall of the connecting shell.

[0011] Furthermore, the inner walls of both the mounting shell and the connecting shell are threaded with threaded rods, the top ends of both threaded rods extend rotatably to the outside of the mounting shell and the connecting shell, and the top ends of both threaded rods are fixedly connected with knobs.

[0012] Furthermore, the outer walls of both threaded rods are threadedly connected to second clamping shells, and the outer walls of both second clamping shells are slidably connected to the outer walls of several connecting rods. The front side of the mounting shell and the rear side of the connecting shell are both fixedly connected to external threaded shells.

[0013] Furthermore, the outer walls of both connecting lines are slidably connected to the inner walls of the two external threaded shells, and the outer walls of both external threaded shells are threadedly connected to internal threaded shells. The outer walls of both connecting lines are in contact with the inner walls of the two internal threaded shells.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up an installation mechanism, first open the two covers, then connect the two connecting wires to the two inserts and sockets respectively through the connecting mechanism. The two inserts and the mounting shell form a plug, and the two sockets and the connecting shell form a socket. Then, press the two push shells to drive the two sliding shells to slide on the two fixed rods and move towards the center of the mounting shell. At this time, the two sliding shells compress the two springs and deform. Then, the two sliding shells drive their own several plug rods to move towards the center of the mounting shell, and then the mounting shell and the connecting shell come into contact, so that the inner walls of the two inserts and the two sockets come into contact. At the same time, the two... The sliding shell slides into contact with the inner wall of the connecting shell, then disengages from the pressure on the two push shells. Subsequently, the two springs rebound, causing the two sliding shells and their respective plug rods to return to their original positions. This ensures that all the plug rods are in contact with the inner wall of the connecting shell, making the sliding shell, mounting shell, and the two plug shells, along with the connecting shell and the two sockets, form a limiting connection. This effectively ensures that the plug and socket are tightly connected. Through the above operation, it is ensured that the plug and socket fit tightly during connection, effectively preventing loosening of the connection with the socket due to external pulling or moving of the plug, thereby ensuring the stability and accuracy of thermocouple signal transmission.

[0016] 2. By setting up a connecting mechanism, two connecting wires are passed through two external threaded shells and two internal threaded shells respectively into the mounting shell and the connecting shell. Then, rotating the two internal threaded shells limits the two connecting wires inside the two external threaded shells. Next, the wires inside the front and rear connecting wires pass through the inner walls of the two first clamping shells and exit. Then, the two covers are opened, and the two knobs are rotated. The two knobs drive the two threaded rods to rotate, and the two threaded rods drive the two second clamping shells to slide and move downwards on the outer walls of the two connecting rods. The two second clamping shells limit and clamp the wires inside the two connecting wires inside the first clamping shells. This allows the wires of the connecting wires to be connected separately and intermittently, preventing... To prevent wire tangling, the internal wires of the two connecting wires are connected to the inner walls of the front and rear inserts respectively using bolts. The rear connecting wire is then connected to the data collection device. The main body then operates. Through the above operations, the external and internal threaded shells are combined, allowing the two connecting wires to be smoothly installed and fixed inside the mounting and connecting shells. This makes the installation and removal of the thermocouple and connecting wires easier. At the same time, the cooperation of the first and second clamps effectively separates the internal wires of the two connecting wires, preventing them from tangling. This effectively reduces the risk of poor contact and avoids signal loss or measurement errors caused by wire tangling, thereby ensuring the accuracy of data acquisition.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 As shown, this utility model is a pluggable thermocouple structure for a powder metallurgy sintering furnace, including a mounting shell 1, a connecting shell 11 provided on the rear side of the mounting shell 1, the front side of the connecting shell 11 contacting the rear side of the mounting shell 1, and also including;

[0028] Mounting mechanism 2 includes a cover 21 hinged to the top of mounting shell 1 and connecting shell 11. Two insert shells 22 are fixedly connected to the rear side of the inner wall of mounting shell 1, with the rear sides of both insert shells 22 extending to the outside of mounting shell 1. Two insert sleeves 23 are fixedly connected to the front side of the inner wall of connecting shell 11, with the front sides of both insert sleeves 23 extending to the outside of connecting shell 11. The outer walls of both insert shells 22 are slidably connected to the inner walls of both insert sleeves 23. Two fixing rods 24 are fixedly connected to the inner wall of mounting shell 1, with sliding shells 25 slidably connected to the outer walls of both fixing rods 24. The outer walls of both sliding shells 25 are slidably connected to the inner wall of mounting shell 1 and connecting shell 11. The inner wall is slidably connected. Push shells 26 are fixedly connected to the left side of the left sliding shell 25 and the right side of the right sliding shell 25. The outer walls of the two push shells 26 are slidably connected to the outer walls of the two fixed rods 24. First, open the two cover shells 21. Then, the two connecting lines 11 are connected to the two plug shells 22 and the plug sleeves 23 respectively through the connecting mechanism 3. The two plug shells 22 and the mounting shell 1 form a plug, and the two plug sleeves 23 and the connecting shell 11 form a socket. Then, press the two push shells 26 to drive the two sliding shells 25 to slide on the two fixed rods 24 and move towards the center of the mounting shell 1. At this time, the two sliding shells 25 compress the two springs 28 to produce deformation.

[0029] Both push shells 26 slide to the outside of the mounting shell 1. Several insert rods 27 are fixedly connected to the left side of the left slide shell 25 and the right side of the right slide shell 25. The outer walls of the insert rods 27 are slidably connected to the inner wall of the connecting shell 11. The outer walls of the two fixed rods 24 are wound with springs 28. One end of the two springs 28 is fixedly connected to the inner wall of the two mounting shells 1, and the other end of the two springs 28 is fixedly connected to the outer wall of the two slide shells 25. Then, the two slide shells 25 drive their insert rods 27 to move towards the center of the mounting shell 1, and then the mounting shell 1 and the connecting shell 11 come into contact, so that the inner walls of the two insert shells 22 and the two insert sleeves 23 come into contact. At the same time, the two slide shells 25 slide to the inner wall of the connecting shell 11, and then release the pressure on the two push shells 26. Then, the two springs 28 rebound and drive the two slide shells 25 and their insert rods 27 to reset.

[0030] The mounting housing 1 is internally equipped with a connecting mechanism 3, which includes a connecting line 31 that slides between the inner walls of the mounting housing 1 and the connecting housing 11. This allows several plugs 27 to contact the inner wall of the connecting housing 11, and the sliding housing 25, the mounting housing 1, and the two plugs 22 to be connected together with the connecting housing 11 and the two sockets 23. This effectively ensures that the plug and socket are tightly connected. Through the above operation, it is ensured that the plug and socket fit tightly during connection, which can effectively prevent the connection with the socket from becoming loose due to external pulling or moving of the plug, thereby ensuring the stability and accuracy of thermocouple signal transmission.

[0031] Both connecting wires 31 extend to the outside of the mounting shell 1 and the connecting shell 11. The other end of the connecting wire 31 located on the front side is fixedly connected to the main body 32, which refers to the thermocouple.

[0032] The bottom of the inner wall of the mounting shell 1 and the bottom of the inner wall of the connecting shell 11 are both fixedly connected to the first clamping shell 33. The inner walls of the mounting shell 1 and the inner walls of the connecting shell 11 are both fixedly connected to several connecting rods 34. When the two covers 21 are opened, the two knobs 36 are rotated. The two knobs 36 drive the two threaded rods 35 to rotate. The two threaded rods 35 drive the two second clamping shells 37 to slide on the outer wall of the two connecting rods 34 and move downward.

[0033] Both the mounting shell 1 and the connecting shell 11 have threaded rods 35 threaded to their inner walls. The tops of the two threaded rods 35 extend rotatably to the outside of the mounting shell 1 and the connecting shell 11. The tops of the two threaded rods 35 are fixedly connected to knobs 36. The two knobs 36 drive the two threaded rods 35 to rotate. The two threaded rods 35 drive the two second clamping shells 37 to slide on the outer wall of the two connecting rods 34 and move downward. The two second clamping shells 37 limit and clamp the wires inside the two connecting wires 31 inside the first clamping shell 33, which allows the wires of the connecting wires 31 to be connected separately and prevents the wires from getting tangled.

[0034] The outer walls of the two threaded rods 35 are threadedly connected to the second clamping shells 37. The outer walls of the two second clamping shells 37 are slidably connected to the outer walls of several connecting rods 34. The front side of the mounting shell 1 and the rear side of the connecting shell 11 are fixedly connected to the external threaded shells 38. The two connecting wires 31 are passed through the two external threaded shells 38 and the two internal threaded shells 39 and respectively inserted into the interior of the mounting shell 1 and the connecting shell 11. Then, the two internal threaded shells 39 are rotated to limit the two connecting wires 31 inside the two external threaded shells 38.

[0035] The outer walls of both connecting wires 31 are slidably connected to the inner walls of both external threaded shells 38. Both external threaded shells 38 are threadedly connected to internal threaded shells 39. The outer walls of both connecting wires 31 are in contact with the inner walls of both internal threaded shells 39. The internal wires of the two connecting wires 31 are then connected to the inner walls of the front insert shell 22 and the rear insert sleeve 23 respectively via bolts. The rear connecting wire 31 is then connected to the data collection device. The main body 32 then operates. This operation allows the external threaded shells 38 and internal threaded shells 39 to be joined, enabling the two connecting wires 31 to be smoothly installed and fixed inside the mounting shell 1 and the connecting shell 11. This simplifies the installation and removal of the thermocouple and connecting wires 31. Simultaneously, the cooperation of the first clamp shell 33 and the second clamp shell 37 effectively separates the internal wires of the two connecting wires 31, preventing them from tangling. This effectively reduces the risk of poor contact and avoids signal loss or measurement errors caused by wire tangling, thus ensuring the accuracy of data acquisition.

[0036] A specific application of this embodiment is as follows: When using the device, first open the two cover shells 21, then connect the two connecting wires 11 to the two insert shells 22 and the two sockets 23 respectively through the connecting mechanism 3. The two insert shells 22 and the mounting shell 1 form a plug, and the two sockets 23 and the connecting shell 11 form a socket. Then, press the two push shells 26 to drive the two sliding shells 25 to slide on the two fixed rods 24 and move towards the center of the mounting shell 1. At this time, the two sliding shells 25 compress the two springs 28 to produce deformation. Then, the two sliding shells 25 drive their own several plug rods 27 to move towards the center of the mounting shell 1. Then, the mounting shell 1 and the connecting shell 11 are brought into contact, so that the two insert shells 22 and the two sockets 23... The inner walls of the two sliding shells 25 and the two sliding shells 26 are in contact with each other, and the two sliding shells 25 are slidably connected to the inner wall of the connecting shell 11. Then, the two springs 28 are released from the pressure on the two sliding shells 26. Subsequently, the two springs 28 rebound and drive the two sliding shells 25 and their several plug rods 27 to reset. This makes the several plug rods 27 contact the inner wall of the connecting shell 11, so that the sliding shells 25, the mounting shell 1, and the two plug shells 22 are limited and connected together with the connecting shell 11 and the two plug sleeves 23. This effectively makes the plug and socket tightly connected together. Through the above operation, it can be ensured that the plug and socket fit tightly when connected, which can effectively prevent the connection with the socket from loosening due to external force pulling or moving the plug, thereby ensuring the stability and accuracy of thermocouple signal transmission.

[0037] When using this device, the two connecting wires 31 are passed through the two external threaded shells 38 and the two internal threaded shells 39, respectively, and inserted into the mounting shell 1 and the connecting shell 11. Then, the two internal threaded shells 39 are rotated to confine the two connecting wires 31 inside the two external threaded shells 38. Then, the wires inside the front and rear connecting wires 31 are passed through the inner walls of the two first clamping shells 33 and exit. Then, the two covers 21 are opened, and the two knobs 36 are rotated. The two knobs 36 drive the two threaded rods 35 to rotate. The two threaded rods 35 drive the two second clamping shells 37 to slide and move downward on the outer walls of the two connecting rods 34. The two second clamping shells 37 confine and clamp the wires inside the two connecting wires 31 inside the first clamping shells 33, which allows the wires of the connecting wires 31 to be connected separately. To prevent wire tangling, the internal wires of the two connecting wires 31 are connected to the inner walls of the front insert 22 and the rear insert 23 respectively using bolts. Then, the rear connecting wire 31 is connected to the data collection device. After that, the main body 32 is used for operation. Through the above operation, the external threaded shell 38 and the internal threaded shell 39 are combined, so that the two connecting wires 31 can be smoothly installed and fixed inside the mounting shell 1 and the connecting shell 11. This makes the installation and disassembly of the thermocouple and the connecting wires 31 easier. At the same time, through the cooperation of the first clamp 33 and the second clamp 37, the internal wires of the two connecting wires 31 can be effectively separated to prevent the wires from tangling. This effectively reduces the risk of poor contact and avoids signal loss or measurement errors caused by wire tangling, thereby ensuring the accuracy of data acquisition.
