Description

Technical Field

[0001] The utility model belongs to the technical field of temperature sensing, and in particular relates to a thermistor temperature sensor device. Background Art

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. Temperature sensors are the core of temperature measuring instruments. There are many varieties of temperature sensors. According to the sensor material and electronic component characteristics, they are divided into two categories: thermal resistors and thermocouples. Thermistors are made of semiconductor materials and most of them have a negative temperature coefficient, that is, the resistance decreases as the temperature increases. Temperature changes will cause large changes in resistance, so it is the most sensitive temperature sensor. Most thermistor temperature sensors sense temperature through temperature control probes and monitor temperature changes through changes in resistance.

[0003] The temperature control probe is fixed on the sleeve on one side of the temperature sensor body. Although the sleeves now have different specifications, the sleeve length cannot be changed once it is fixed. When in use, it is necessary to select the corresponding sleeve length according to the insertion depth. At this time, either replace the temperature sensor with a different sleeve length, which requires preparing multiple temperature sensors of different lengths, which is costly, or replace the sleeve on a single temperature sensor, which requires disassembly and the need to carry and prepare sleeves of different lengths, which is more troublesome. Summary of the invention

[0004] In order to solve the above problems, the purpose of the utility model is to provide a thermistor temperature sensor device.

[0005] To achieve the above-mentioned purpose, the utility model proposes a thermistor temperature sensor device, including a thermistor component, a telescopic assembly is provided on one side of the thermistor component, a connecting wire is installed on one side of the thermistor component, one end of the connecting wire is fixedly connected to a detection probe, the detection probe is electrically connected to the thermistor component through the connecting wire, and a mounting device is provided between the detection probe and the telescopic assembly.

[0006] In one example, the telescopic assembly includes a fixed tube, which is fixedly connected to the thermistor component, and a spiral groove is provided inside the fixed tube. An inner tube is placed inside the fixed tube, and the outer wall of the inner tube is attached to the inner wall of the fixed tube. The outer side of the inner tube is fixedly connected to a sliding block, and the sliding block cooperates with the spiral groove. The sliding block can slide along the spiral groove, and the connecting line passes through the fixed tube and the inner tube.

[0007] In one example, the outer side of the sliding block is fixedly connected to a high temperature resistant rubber sleeve, and the rubber sleeve is elastic.

[0008] In one example, the mounting device includes a fixing ring, which is fixedly connected to the inner tube. The fixing ring is located on the side of the inner tube away from the fixing tube. One side of the detection probe is rotatably connected to a rotating seat. The rotating seat is a hollow structure. The connecting wire passes through the rotating seat. The rotating seat is provided with an external thread. The inner side of the fixing ring is provided with an internal thread, and the external thread matches the internal thread.

[0009] In one example, a metal hose is installed on the outside of the connecting line.

[0010] In one example, the inner tube and the fixed tube are both made of high temperature resistant materials.

[0011] The thermistor temperature sensor device proposed by the utility model can bring the following beneficial effects:

[0012] First, by setting a fixed tube and an inner tube, rotating the inner tube, the inner tube rotates inside the fixed tube, and under the action of the sliding block and the spiral groove, the inner tube moves spirally, thereby increasing or decreasing the distance between the detection probe and the thermistor component, which is more convenient to use;

[0013] Secondly, by setting a rotating seat and a fixed ring, the detection probe is fixed on the inner tube through the fixed ring and the rotating seat, and the fixed ring and the rotating seat are connected through internal threads and external threads. The rotating seat is rotated to remove the detection probe, and the inner tube is retracted into the fixed tube to expose the connecting wire. At this time, the detection probe can move freely within the range of the connecting wire, and it is more flexible to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1 to Figure 4 As shown, an embodiment of the utility model proposes a thermistor temperature sensor device, including a thermistor component 1, a telescopic component 2 is provided on one side of the thermistor component 1, a connecting wire 3 is installed on one side of the thermistor component 1, one end of the connecting wire 3 is fixedly connected to a detection probe 4, the detection probe 4 is electrically connected to the thermistor component 1 through the connecting wire 3, a mounting device 5 is provided between the detection probe 4 and the telescopic component 2, the detection temperature is sensed by the detection probe 4, the detection probe 4 can be mounted on the telescopic component 2 through the mounting device 5, the distance between the detection probe 4 and the thermistor component 1 is adjusted by the telescopic component 2, at this time, the detection probe 4 and the telescopic component 2 form a structure similar to a detection probe, and the detection probe can be adjusted in length, and the detection probe 4 can also be removed from the telescopic component 2 through the mounting device 5, the telescopic component 2 is contracted, and the internal wires are exposed, at this time, the detection probe 4 can move freely within the range of the connecting wire 3, and is flexible to use. Different modes can be adjusted according to different use environments, and the use adaptability is wider.

[0027] Specifically, the telescopic assembly 2 includes a fixed tube 21, which is fixedly connected to the thermistor component 1. A spiral groove 22 is provided inside the fixed tube 21. An inner tube 23 is placed inside the fixed tube 21. The outer wall of the inner tube 23 is attached to the inner wall of the fixed tube 21. The outer side of the inner tube 23 is fixedly connected to a sliding block 24. The sliding block 24 cooperates with the spiral groove 22. The sliding block 24 can slide along the spiral groove 22. The connecting line 3 passes through the fixed tube 21 and the inner tube 23, and the inner tube 23 is rotated. The inner tube 23 rotates inside the fixed tube 21. Under the action of the sliding block 24 and the spiral groove 22, the inner tube 23 moves in a spiral shape, and the distance between the detection probe 4 and the thermistor component 1 is adjusted, which is more convenient.

[0028] Specifically, the outer side of the sliding block 24 is fixedly connected to a high temperature resistant rubber sleeve, which is elastic and can increase the friction between the sliding block 24 and the spiral groove 22. When the inner tube 23 stops rotating, the inner tube 23 can be fixed by friction to prevent the inner tube 23 from sliding in the fixed tube 21 without external force.

[0029] Specifically, the mounting device 5 includes a fixing ring 51, which is fixedly connected to the inner tube 23. The fixing ring 51 is located on the side of the inner tube away from the fixing tube 21. One side of the detection probe 4 is rotatably connected to the rotating seat 52.

The inner side of the fixing ring 51 is provided with an internal thread. The external thread cooperates with the internal thread. The detection probe 4 is fixed to the inner tube 23 through the fixing ring 51 and the rotating seat 52. The fixing ring 51 and the rotating seat 52 are connected through the internal thread and the external thread. The rotating seat 52 can be directly rotated during disassembly or installation. The structure is simple to operate. The rotating seat 52 is rotatably connected to the detection probe 4. When the rotating seat 52 is rotated, the connecting line 3 will not be tightened, thereby avoiding squeezing the rubber of the connecting line 3 and causing deformation of the connecting line 3.

[0030] Specifically, a metal hose is installed on the outside of the connecting wire 3, and the metal hose provides protection for the connecting wire 3, prolongs the service life of the connecting wire 3, and reduces wear.

[0031] Specifically, the inner tube 23 and the fixed tube 21 are both made of high temperature resistant materials, and can be kept in a high temperature environment for a long time to avoid deformation of the inner tube 23 and the fixed tube 21 .

[0032] Working principle: When in use, different modes are adjusted according to different usage environments. The detection probe 4 is installed on the inner tube 23 through the rotating seat 52 and the fixed ring 51. At this time, the inner tube 23 can be rotated, and the inner tube 23 rotates inside the fixed tube 21. Under the action of the sliding block 24 and the spiral groove 22, the inner tube 23 moves in a spiral shape to increase or decrease the distance between the detection probe 4 and the thermistor component 1. The rotating seat 52 can also be rotated to remove the detection probe 4 from the inner tube 23, and the inner tube 23 can be rotated at the same time to retract the inner tube 23 into the fixed tube 21 to expose the connecting line 3. At this time, the detection probe 4 can move freely within the range of the connecting line 3.
