Description

Technical Field

[0001] This utility model relates to the field of sensor probe technology, and in particular to an NTC temperature sensor probe. Background Technology

[0002] Temperature sensor probes employ the contact method and are primarily used for food sampling inspection, temperature monitoring during food transportation, measurement of the center temperature of flowing flue gas in flues, and measurement of temperature differences at different points. In electronic welding, surface temperature measurement is used to detect preheating conditions. In chemical reaction processes, immersion measurement is used to measure the temperature of chemical solutions. In the machinery manufacturing industry, surface temperature measurement of bearings and gears is used for maintenance and repair.

[0003] For example, Chinese utility model patent application number 202323549736.8 discloses an NTC temperature sensor probe, including a wire with a connector at one end and the wire being fixedly connected to the connector; it also includes a probe holder, which is disposed on one side of the connector and fixedly connected to the connector, with an annular iron piece disposed on one side of the probe holder and fixedly connected to the probe holder; and a protective sleeve, which is disposed on one side of the annular iron piece, with an annular magnet disposed between the protective sleeve and the annular iron piece, and the annular magnet being fixedly connected to the open end of the protective sleeve. This structure allows for flexible disassembly and assembly of the protective device and makes the surface of the temperature sensor probe easy to clean.

[0004] Although the device in the aforementioned patent can easily disassemble and assemble the protective device and facilitate cleaning of the temperature sensor surface, in actual use, the connection between the fixing ring and the sensor probe is relatively tight, making it inconvenient to insert the sensor probe into the protective device. It is also easy for the probe to collide with the fixing ring, resulting in unnecessary collisions and damage, which reduces the practicality of the device. Utility Model Content

[0030] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1-4 This utility model provides an NTC temperature sensor probe, comprising a wire 1, a connector 2 fixedly connected to the outer surface of the wire 1, a probe body 3 and a protective cover 4 disposed on one side of the connector 2, a connecting strap 14 fixedly connected to the outer surface of the protective cover 4, and several arc-shaped grooves 5 extending through the other side of the protective cover 4, a connecting rod 6 disposed inside the arc-shaped grooves 5, the diameter of the connecting rod 6 being adapted to the arc-shaped grooves 5, a mounting plate 7 fixedly connected to the outer surface of the connecting rod 6, a protective cotton 8 disposed on the mounting plate 7, the protective cotton 8 being arc-shaped, an adjusting frame 9 disposed on one side of the protective cover 4, and several sliding grooves 10 disposed inside the adjusting frame 9, the sliding grooves 10 being arranged in a circumferential array inside the adjusting frame 9. The wall has the same number of arc-shaped grooves 5 and sliding grooves 10. Each of the sliding grooves 10 has a slider 11 slidably connected inside. One side of the slider 11 is fixedly connected to one end of the connecting rod 6. The protective cover 4 is equipped with a fixing component. Through the cooperation of the wire 1, connecting seat 2, protective cover 4, arc-shaped groove 5, connecting rod 6, protective cotton 8, adjusting frame 9, sliding groove 10, slider 11 and rubber block 20, the protective cotton 8 can be easily moved to the outer surface of the probe body 3 after the probe body 3 is inserted into the protective cover 4 to wipe the probe body 3. This can prevent unnecessary collisions and damage to the probe body 3, which not only improves the safety of the probe cleaning process, but also improves the practicality of the device.

[0032] A metal ring 12 is fixedly embedded on one side of the connector 2, and a permanent magnet 13 is fixedly embedded on one side of the protective cover 4. The permanent magnet 13 is arranged in a ring and is magnetically connected to the metal ring 12. The arrangement of the metal ring 12 and the permanent magnet 13 can initially fix the protective cover 4 to prevent it from falling off and damaging the probe body 3.

[0033] An annular groove 15 is provided on one side of the protective cover 4. An annular block 16 is slidably connected inside the annular groove 15. The annular block 16 is fixedly connected to one side of the adjusting frame 9. Through the setting of the annular groove 15 and the annular block 16, the adjusting frame 9 can be rotated, which drives the connecting rod 6 to move.

[0034] The fixing assembly includes four connecting brackets 17, all of which are fixedly connected to the outer surface of the protective cover 4. Each of the four connecting brackets 17 is rotatably connected to a rotating shaft 18. A pressing plate 19 and a rubber block 20 are fixedly connected to the outer surface of the rotating shaft 18. Through the setting of the fixing assembly, the protective cover 4 can be fixed in a secondary way, preventing it from moving or falling off due to collision or squeezing, and thus preventing collision with the probe body 3 and damage to the probe body 3, thereby improving the stability of the protective cover 4 during use.

[0035] Working principle: When in use, rotate the two pressing plates 19 on the side near the connecting seat 2, so that they drive the corresponding rotating shaft 18 to rotate. The rotation drives the corresponding rubber block 20 to rotate, so that it no longer abuts against the connecting seat 2. Then, the protective cover 4, the adjusting frame 9 and the permanent magnet 13 can be moved away from the side of the connecting seat 2. After the permanent magnet 13 is magnetically separated from the metal ring 12, the probe body 3 can be removed from the inside of the protective cover 4 for easy use or cleaning.

[0036] After the probe is used, it can be directly inserted into the protective cover 4. After the permanent magnet 13 is magnetically connected to the metal ring 12, the other two pressing plates 19 are rotated. The corresponding rubber blocks 20 rotate, releasing the limit on the adjustment frame 9. The adjustment frame 9 is then rotated, causing several connecting rods 6 to rotate. Under the guidance of the arc groove 5, the slider 11 moves down, causing the corresponding connecting rods 6, mounting plate 7, and protective cotton 8 to move down synchronously. The protective cotton 8 can then come into contact with the outer surface of the probe. After the two pressing plates 19 are reset and the adjustment frame 9 is fixed and limited, the entire protective cover 4 can be rotated. The protective cotton 8 can then wipe its outer surface. After wiping, the two pressing plates 19 can be squeezed again to make them rotate, thereby firmly abutting the corresponding rubber blocks 20 against the outer surface of the connecting seat 2, thus fixing the protective cover 4 a second time to prevent it from falling off due to collision and improving the stability of its connection.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
