Technical Field

[0001] The utility model relates to the technical field of temperature sensors, in particular to a thermocouple temperature sensor. Background Art

[0002] Thermocouple temperature sensors are the most commonly used contact temperature measuring devices in industry. This is because thermocouple temperature sensors have the characteristics of stable performance, large temperature measurement range, long-distance signal transmission, simple structure and easy use. Thermocouple temperature sensors can directly convert thermal energy into electrical signals and output DC voltage signals, making it easy to display, record and transmit.

[0003] For example, the thermocouple temperature sensor with publication number CN209841225U includes a heat conducting sheet. The convenience of the temperature sensor is improved, whether it is welding and fixing the heat conducting sheet to the steel casing or subsequent packaging, thereby improving the manufacturing efficiency;

[0004] The thermocouple temperature sensor is sealed by a plug on the right side of the steel casing, and then epoxy resin glue is applied in the annular gap between the plug and the wire. However, when fixed in this way, after a period of use, once the thermocouple in the steel casing fails, it cannot be disassembled, repaired or replaced, and the thermocouple temperature sensor needs to be replaced as a whole, which has a high actual use cost. In view of this, it is very necessary to design a thermocouple temperature sensor to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a thermocouple temperature sensor, which solves the problem of the existing thermocouple temperature sensor that, because the connection is fixed by applying epoxy resin glue, once the thermocouple in the steel sleeve fails, it cannot be disassembled, repaired and replaced, and the thermocouple temperature sensor needs to be replaced as a whole, which results in a high actual use cost.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a thermocouple temperature sensor, comprising a temperature sensor body and a baffle, the right outer wall of the temperature sensor body is fitted with the baffle, the left side of the baffle is fixed with a plug, and the outer wall of the plug and the inner wall of the temperature sensor body are gap-matched, the left outer wall of the plug is fitted with a baffle ring fixed with the inner wall of the temperature sensor body, a fixing mechanism is installed on the left side of the baffle, and a connecting mechanism is installed inside the temperature sensor body.

[0007] Preferably, the fixing mechanism includes a plurality of concave plates fixed to the left outer wall of the baffle cover, and the grooves of the concave plates are rotatably connected to a pair of connecting rods via a rotating shaft, a disk fixed to the outer wall of the temperature sensor body is installed at the left end of the connecting rod, and the inner wall of the elliptical groove of the disk is gap-matched with the outer wall of the left end of the connecting rod, a slider is slidably clamped at the sliding groove of the connecting rod, and the outer wall of the adjacent slider is rotatably connected to a torsion spring via a rotating shaft.

[0008] Preferably, the outer wall of the plug is sleeved with a sealing ring that fits the inner wall of the temperature sensor body.

[0009] Preferably, the connection mechanism comprises a wire sleeve fixedly connected to the inside of the blocking cover, a pair of wires are fixedly connected to the inside of the wire sleeve, and a thermocouple and a wiring clip are respectively connected to the left and right sides of the wires.

[0010] Preferably, the interior of the temperature sensor body is filled with a filler.

[0011] Preferably, a blocking wire is threadedly connected to the upper left side of the temperature sensor body.

[0012] Beneficial Effects

[0013] The utility model provides a thermocouple temperature sensor, which has the following beneficial effects:

[0014] The sealing ring can be put onto the plug, and then the wire sleeve and the plug can be driven to move into the interior of the temperature sensor body through the blocking cover. The wire sleeve drives the thermocouple into the interior of the temperature sensor body through the wire. Then, a pair of connecting rods are pressed to make the connecting rod drive the slider to move. The slider squeezes the torsion spring to make the torsion spring elastically deform. Then, the left ends of the pair of connecting rods are made to enter the elliptical groove of the disc. Then, the connecting rods are released to reset the connecting rods under the elastic force of the torsion spring. In this way, the connecting rods can be stuck in the elliptical groove of the disc, thereby fixing the blocking cover and the plug on the temperature sensor body. Finally, the filler is filled into the temperature sensor body, and the plugging wire is installed to seal it. In this way, the overall assembly of the thermocouple temperature sensor is completed. On the contrary, if the thermocouple fails, it can be quickly disassembled and repaired, so there is no need to replace the device as a whole, so that the actual use cost is low.
