Description

Technical Field

[0001] This utility model relates to the field of temperature measuring device technology, and in particular to an automatic temperature measuring device for high-temperature nitriding kilns that is easy to install, disassemble and maintain. Background Technology

[0002] In the process of high-temperature nitriding kiln, accurate and continuous monitoring of kiln temperature is crucial. Traditional manual temperature measurement methods have significant limitations. Operators need to be in close contact with the high-temperature kiln body, facing a serious risk of burns, resulting in a low safety factor. At the same time, manual intermittent temperature measurement cannot capture the dynamic changes in kiln temperature in real time. Especially in the critical heating, holding and cooling stages, the lack or lag of temperature data can easily lead to fluctuations in product quality or even scrapping. In addition, there is usually a corrosive gas environment inside the kiln, which causes great wear and tear on temperature measuring instruments.

[0003] Currently, automatic temperature measuring devices for high-temperature nitriding kilns use thermocouples to automatically measure the temperature inside the kiln. However, due to the high temperature, thermocouples need to be frequently disassembled and maintained, resulting in a significant waste of time in installation and disassembly. Traditional threaded installation is also cumbersome, and during use, they may loosen due to pulling, leading to discrepancies between the measured results and the actual situation, which in turn affects the processing conditions inside the nitriding kiln. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic temperature measuring device for high-temperature nitriding kilns that is easy to install, disassemble, and maintain includes:

[0006] The outer casing and three thermocouples are provided. Two support plates are fixedly connected to the side wall of the outer casing. A display screen is fixedly installed on the side wall of the outer casing. Multiple buttons are installed on the side wall of the outer casing.

[0007] The outer housing is equipped with a quick-installation structure, which includes three bidirectional screws rotatably connected to the side wall of the outer housing. Adjacent bidirectional screws are fixedly connected to each other via connecting shafts. One end of each bidirectional screw is fixedly connected to a rotating shaft. Two sliding rods are threadedly connected to the outer sides of each of the three bidirectional screws. A clamping plate is fixedly connected to the side wall of each sliding rod, and a buffer structure is also installed on the clamping plate. A fixing rod is fixedly connected to the side wall of the outer housing, and the fixing rod is slidably connected to multiple sliding rods. Two iron blocks are fixedly connected to the side walls of each of the three thermocouples. Six magnets are fixedly connected to the lower side of the outer housing.

[0008] Preferably, a locking structure is installed on the outer housing. The locking structure includes a ratchet fixedly sleeved on the outside of the rotating shaft, a rotating rod rotatably connected to the side wall of the outer housing, a pawl fixedly connected to one end of the rotating rod, a torsion spring fixedly connected between the pawl and the outer housing, and a toggle lever fixedly connected to the side wall of the pawl.

[0009] Preferably, the buffer structure includes two round rods slidably connected to the side wall of the clamping plate, one end of the two round rods is fixedly connected to a buffer plate, the other end of the two round rods is fixedly connected to a fixing block, and a buffer spring is fixedly connected between the two fixing blocks and the clamping plate.

[0010] Preferably, a frame is fixedly connected to the side wall of the outer shell, two electric fans are fixedly installed on the side wall of the frame, and multiple ventilation openings are opened on the side wall of the frame.

[0011] Preferably, the outer housing sidewall is fixedly connected with three clamping rings.

[0012] Preferably, a knob is fixedly connected to one end of the rotating shaft.

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

[0014] 1. In this utility model, the quick installation structure enables the simultaneous disassembly and installation of three thermocouples. First, the thermocouples are initially positioned using magnets and iron blocks, and then the clamping plate clamps and fixes them by rotating the knob, which greatly reduces the time required for installation and disassembly.

[0015] 2. In this utility model, the locking structure can lock the clamping and fixing, which avoids the rotation of the bidirectional screw due to special circumstances during use, thus preventing the clamping and fixing from loosening, and making the clamping and fixing effect better.

[0016] In these three utility models, the buffer structure can reduce the clamping damage to the thermocouple during the fixing process. Attached Figure Description

[0024] Reference Figures 1-6 An automatic temperature measuring device for high-temperature nitriding kilns, which is easy to install, disassemble, and maintain, includes:

[0025] The outer casing 1 consists of three thermocouples 2. Two support plates 3 are fixedly connected to the side wall of the outer casing 1. The two support plates 3 are fixed to the nitriding kiln by bolts. A display screen 4 is fixedly installed on the side wall of the outer casing 1. Multiple buttons are installed on the side wall of the outer casing 1. The outer casing 1 contains multiple circuits. The display screen 4 can display the temperature detected by the thermocouples 2. A frame 18 is fixedly connected to the side wall of the outer casing 1. Two electric fans 19 are fixedly installed on the side wall of the frame 18. The electric fans 19 consist of a motor and a fan. The electric fans 19 can blow air to cool the outer casing 1. Multiple ventilation holes are opened on the side wall of the frame 18. The multiple ventilation holes can form an air duct to achieve the effect of air circulation. Three clamping rings 20 are fixedly connected to the side wall of the outer casing 1. The three clamping rings 20 can clamp the three thermocouples 2 respectively, which facilitates the storage of the thermocouples 2.

[0026] A quick-installation structure is installed on the outer housing 1. This quick-installation structure includes three bidirectional screws 5 rotatably connected to the side wall of the outer housing 1, with adjacent bidirectional screws 5 fixedly connected by a connecting shaft. One end of each bidirectional screw 5 is fixedly connected to a rotating shaft 6, and the other end of the rotating shaft 6 is fixedly connected to a knob 21. Two sliding rods 7 are threadedly connected to the outer sides of each of the three bidirectional screws 5. Rotation of the bidirectional screws 5 causes the two threaded sliding rods 7 to move towards each other. A clamping plate 8 is fixedly connected to the side wall of each sliding rod 7. A buffer structure is also installed on the clamping plate 8, and the buffer structure includes components slidably connected to the side wall of the clamping plate 8. Two round rods 16 are fixedly connected to a buffer plate 23 at one end, and a fixing block is fixedly connected to the other end of each of the two round rods 16. A buffer spring 17 is fixedly connected between each of the two fixing blocks and the clamping plate 8. The buffer plate 23 can reduce damage to the thermocouple 2 during clamping. A fixing rod 22 is fixedly connected to the side wall of the outer shell 1. The fixing rod 22 is slidably connected to multiple sliding rods 7. Two iron blocks 9 are fixedly connected to the side walls of the three thermocouples 2. Six magnets 10 are fixedly connected to the lower side of the outer shell 1. The iron blocks 9 and the magnets 10 match to enable the thermocouple 2 to be initially fixed.

[0027] A locking structure is installed on the outer housing 1. The locking structure includes a ratchet 11 fixedly sleeved on the outside of the rotating shaft 6. A rotating rod 12 is rotatably connected to the side wall of the outer housing 1. A pawl 13 is fixedly connected to one end of the rotating rod 12. A torsion spring 14 is fixedly connected between the pawl 13 and the outer housing 1. A toggle rod 15 is fixedly connected to the side wall of the pawl 13. By pulling the toggle rod 15, the pawl 13 is lifted upward, so that the pawl 13 no longer blocks the ratchet 11.

[0028] In this invention, firstly, the operator uses magnet 10 and iron block 9 to initially fix thermocouple 2. At this time, rotating knob 21 causes shaft 6 to rotate, which in turn causes three bidirectional screws 5 to rotate, thereby causing sliding rods 7 threaded to the bidirectional screws 5 to move in opposite directions, thus driving clamping plate 8 to clamp and fix thermocouple 2. At the same time, buffer plate 23 and buffer spring 17 provide a buffering effect during clamping. The elasticity of buffer spring 17 reduces the mechanical damage to the surface of thermocouple 2 caused by clamping. When it is necessary to remove thermocouple 2 for maintenance, pulling lever 15 causes pawl 13 to lift upward around lever 12, thus removing the restriction on ratchet 11. With ratchet 11 no longer restricted, shaft 6 can rotate in the opposite direction, which in turn rotates knob 21 in the opposite direction, causing bidirectional screws 5 to rotate in the opposite direction, thereby opening the clamp and allowing thermocouple 2 to be removed.
