Description

Technical Field

[0001] The utility model relates to the technical field of thermocouple fixing, in particular to a thermocouple fixing device outside a high-temperature diffusion furnace. Background Art

[0002] Thermocouples are commonly used temperature measuring elements in temperature measuring instruments. They directly measure temperature and convert temperature signals into thermoelectric potential signals, which are then converted into the temperature of the measured medium through electrical instruments (secondary instruments). The appearance of various thermocouples is often very different due to needs, but their basic structure is roughly the same. They are usually composed of main parts such as thermode, insulating sleeve protection tube and junction box, and are usually used in conjunction with display instruments, recording instruments and electronic regulators.

[0003] In the actual application of high-temperature diffusion furnaces, bolt assemblies are often used to fix external thermocouples. However, it is inconvenient for workers to adjust the position of the thermocouples when bolts are used, and the life of the external thermocouples is short. They often break and fall off, resulting in inaccurate temperature detection. In addition, different bolt assemblies may be required to fix thermocouples of different specifications, which causes trouble. Utility Model Content

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the utility model and their descriptions are only used to explain the utility model and are not intended to limit the utility model.

[0034] This embodiment provides a device for fixing thermocouples outside a high-temperature diffusion furnace. Figure 1 and Figure 2 As shown, including:

[0035] A bracket 1, wherein a working hole 11 is provided in the middle of the bracket 1 for an external thermocouple to pass through;

[0036] A fixing block 2, wherein the fixing block 2 is mounted on the bottom of the bracket 1 through a fixing member 6;

[0037] The clamping block 3 is slidably arranged at the bottom of the bracket 1 and located on one side of the fixing block 2 ; the clamping block 3 is connected to an adjusting member 4 to enable it to slide relative to the fixing block 2 .

[0038] In the prior art, since the external thermocouple is fixed by bolts, it is inconvenient for the staff to adjust the position of the thermocouple by bolts, and the life of the external thermocouple is short, and it often breaks and falls off, resulting in inaccurate temperature detection.

[0039] In order to solve the above problems, the present embodiment is provided with an adjusting member 4, and the clamping block 3 can slide on the bracket 1 to fix or release the thermocouple. Specifically, the working process of the present embodiment is as follows:

[0040] First, the thermocouple passes through the working hole 11 on the bracket 1. The working hole 11 is large enough to allow thermocouples of different specifications to pass through. The bracket 1 is connected to the high-temperature diffusion furnace, and the fixing member 6 firmly connects the fixing block 2 to the bracket 1. At this time, the thermocouple is located between the fixing block 2 and the clamping block 3. The adjustment member 4 is started to move, and the clamping block 3 moves away from the fixing block 2 and increases the distance between the clamping block 3 and the fixing block 2, thereby loosening the thermocouple. At this time, the staff can adjust the position of the thermocouple.

[0041] On the contrary, the adjusting member 4 moves in the opposite direction, and the clamping block 3 moves toward the fixing block 2 and reduces the distance between the clamping block 3 and the fixing block 2 until the clamping block 3 cooperates with the fixing block 2 to fix the thermocouple. At this time, the thermocouple cannot move at will.

[0042] Further, if Figure 2 As shown, in order to facilitate the passage of thermocouples of different specifications, it is configured as follows: the working hole 11 is a strip hole.

[0043] In this embodiment, strip holes are provided on the bracket 1 , on the one hand to facilitate the passage of thermocouples of different specifications, and on the other hand to ensure that the thermocouple can effectively pass through the working hole 11 to avoid bending of the thermocouple due to installation errors of the bracket 1 .

[0044] Furthermore, in order to ensure the stable sliding of the clamping block 3, it is configured as follows: a positioning block 7 is connected to the side of the clamping block 3 in contact with the bracket 1, and a positioning groove 8 cooperating with the positioning block 7 is arranged on the bracket 1 along the moving direction of the clamping block 3. In this embodiment, the clamping block 3 needs to move horizontally to adjust the spacing between it and the fixed block 2. Since the clamping block 3 slides on the bracket 1, the cooperation between the positioning block 7 and the positioning groove 8 can guide the horizontal sliding of the clamping block 3 on the one hand, and can ensure the normal operation of the adjusting member 4 and the fixing of the thermocouple on the other hand.

[0045] In order to ensure stable installation of the bracket 1 and subsequent stable installation with the fixing block 2, it is configured as follows: the middle portion of the bracket 1 is bent into a U-shaped plate, mounting plates 9 are provided on both sides of the bracket 1, and mounting holes 91 are provided on the mounting plates 9.

[0046] In order to increase the service life of the bracket 1, it is set as follows: the bracket 1 is made of stainless steel. The middle part of the bracket 1 is bent and installed and fixed with the high-temperature diffusion furnace through the mounting plates 9 and mounting holes 91 on both sides, ensuring that there is a gap between the middle part of the bracket 1 and the high-temperature diffusion furnace, which is convenient for the subsequent installation of the fixing block 2 and the clamping block 3.

[0047] In order to ensure the stable installation of the fixing block 2 and the bracket 1, it is configured as follows: a first fixing hole 22 is provided on the fixing block 2, and a second fixing hole 12 aligned with the first fixing hole 22 is provided on the bracket 1; the fixing member 6 includes a fixing bolt 61 passing through the first fixing hole 22 and the second fixing hole 12, and one end of the fixing bolt 61 is threadedly connected with a fixing nut 62.

[0048] In this embodiment, the first fixing hole 22 and the second fixing hole 12 are respectively provided on the fixing block 2 and the bracket 1, and then the fixing bolts 61 and the fixing nuts 62 are passed through to achieve fixed installation. It should be understood that the fixed installation of the fixing block 2 and the bracket 1 is not limited to the above-mentioned form, and can also be welding, bonding, etc. Considering the replacement and disassembly of the fixing block 2, this embodiment selects the installation form of bolts and nuts.

[0049] According to another embodiment of the utility model, Figure 3 As shown, the side of the fixing block 2 is provided with an adjustment hole 21, and the adjustment member 4 includes:

[0050] An adjusting bolt 41, one end of which is fixedly connected to the clamping block 3, and the other end of which passes through the adjusting hole 21 and is connected to an adjusting nut 42, wherein, in order to facilitate the staff to pull the clamping block 3, it is configured as follows: a handle 44 is connected to one end of the adjusting bolt 41 close to the clamping block 3.

[0051] The spring 43 is sleeved on the adjusting bolt 41 and is located between the adjusting nut 42 and the side wall in the adjusting hole 21 .

[0052] In this embodiment, the adjustment hole 21 is opened on the side of the fixing block 2, and the adjustment nut 42 is an M5 anti-loosening nut. The setting of the adjustment nut 42 ensures that the adjustment bolt 41 can always be located in the adjustment hole 21, ensuring the connection with the clamping block 3.

[0053] Specifically, the working process of the adjusting member 4 is as follows:

[0054] Pull the handle 44, and the clamping block 3 moves away from the fixed block 2, and the clamping block 3 drives the adjusting bolt 41 and the adjusting nut 42 to move, so that the spring 43 in the adjusting hole 21 is compressed and the fixing of the thermocouple is released, and the position of the thermocouple can be adjusted to ensure that the thermocouple will not loosen or fall off due to long-term use.

[0055] When the handle 44 is released, the adjusting bolt 41 and the adjusting nut 42 rebound, and the clamping block 3 moves toward the fixed block 2 under the elastic force of the spring 43, and then the fixed block 2 and the clamping block 3 are both in contact with the thermocouple and fixed.

[0056] Furthermore, in order to increase the contact area between the positioning block 7 and the clamping block 3 and the external thermocouple for easy clamping and fixing, it is configured that: a V-shaped groove is provided on one side of the fixing block 2 and the clamping block 3 that abuts against the external thermocouple.

[0057] Since the shape of the thermocouple is tubular, the V-shaped groove 5 is provided on the fixing block 2 and the clamping block 3 to form a square space to fix the thermocouple. It should be understood that the V-shaped groove 5 on the fixing block 2 and the clamping block 3 can also be replaced by an arc groove, a square groove, etc. to facilitate the clamping and fixing of the thermocouple. Considering the need to clamp the thermocouple and fix it stably, the V-shaped groove 5 is selected in this embodiment for implementation.

[0058] Furthermore, in order to ensure the service life of the adjusting member 4 and increase the durability of the adjusting bolt 41 , it is configured as follows: the adjusting bolt 41 is made of stainless steel.

[0059] The specific working process of the utility model is:

[0060] First, the thermocouple passes through the working hole 11 on the bracket 1. The working hole 11 is a strip hole so that thermocouples of different specifications can pass through. The bracket 1 is connected to the high-temperature diffusion furnace, and the fixing block 2 and the bracket 1 are firmly installed by the combination of the fixing bolt 61 and the fixing nut 62. At this time, the thermocouple is located between the fixing block 2 and the clamping block 3. Pull the handle 44, and the clamping block 3 moves away from the fixing block 2. The clamping block 3 drives the adjusting bolt 41 and the adjusting nut 42 to move, so that the spring 43 in the adjusting hole 21 is compressed and the fixation of the thermocouple is released at this time, and the thermocouple can be adjusted. To ensure that the thermocouple will not loosen or fall off due to long-term use.

[0061] When the handle 44 is released, the adjusting bolt 41 and the adjusting nut 42 rebound, and the clamping block 3 moves toward the fixed block 2 under the elastic force of the spring 43, and then the fixed block 2 and the clamping block 3 are both in contact with the thermocouple and fixed.

[0062] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
