Description

Technical Field

[0001] This utility model relates to the field of temperature probe housing technology, specifically to a high-temperature resistant housing structure for a lightweight temperature probe. Background Technology

[0002] The primary function of a temperature probe is to measure and sense temperature and convert it into a usable output signal. Specifically, a temperature probe senses temperature changes through its sensitive element and converts them into electrical signals such as changes in voltage, current, or resistance. These signals can be further processed, displayed, or controlled. As a key sensor in industrial process control, environmental monitoring, and scientific research experiments, the design of the temperature probe's housing structure directly affects measurement accuracy, equipment reliability, and service life.

[0003] In the existing technology, the outer shell of the temperature probe is integrally formed with the temperature probe, which does not provide protection against dirt or drops. If the temperature probe is dropped or bumped during use, the outer shell will be deformed or damaged, which will affect the temperature sensing sensitivity and accuracy of the temperature probe and shorten its service life.

This material has high temperature resistance, strong corrosion resistance and stability, and can provide better protection for the internal sensor and other structures of the probe. The mounting tube is a mesh structure. Filling the gap between the mounting tube and the mesh tube with silicone particles can effectively achieve moisture-proof and moisture-absorbing protection for the probe body, prevent the probe from short-circuiting, corroding components or measurement errors due to moisture, and improve the reliability in high temperature and high humidity environments.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3As shown in this embodiment, the high-temperature resistant shell structure of the portable temperature probe includes a probe body 2 and a mounting tube 1. The probe body 2 is located inside the mounting tube 1. A mesh tube 3 is fixedly sleeved on the outside of the mounting tube 1. A cover tube 4 is fixedly sleeved on the outside of the mesh tube 3. A mounting base 5 is fixedly installed below the mesh tube 3 and the cover tube 4. A first closing cover 41 is threadedly sleeved on the top of the mesh tube 3 and the mounting tube 1. A second closing cover 42 is threadedly sleeved on the top of the mesh tube 3 and the cover tube 4. A second rotating ring 23 is rotatably installed inside the mounting base 5. A second toothed ring 24 is sleeved on the second rotating ring 23. Multiple sets of annularly distributed closing plates 25 are rotatably installed inside the mounting base 5. The closing plates 25 are rotatably connected to the mounting base 5 through mounting shafts 26. A second gear 27 is sleeved on each of the multiple sets of mounting shafts 26. All 7 are engaged with the second gear ring 24. Two sets of symmetrically distributed ratchet wheels 28 are sleeved on the right mounting shaft 26. The mounting base 5 has two sets of pawls 29 that are respectively engaged with the two sets of ratchet wheels 28. Both sets of pawls 29 are rotatably connected to the mounting base 5 through rotating rods 30. A first torsion spring 31 is sleeved on the rotating rod 30. The two ends of the first torsion spring 31 are respectively fixedly connected to the pawls 29 and the mounting base 5. A third gear 32 is sleeved on both sets of rotating rods 30. Two sets of racks 33 that are respectively engaged with the third gears 32 are slidably installed in the mounting base 5. A slide 34 is slidably installed in the mounting base 5. The two ends of the slide 34 are respectively fixedly connected to the two sets of racks 33. A slide rod 35 is fixedly installed in the mounting base 5. The slide 34 and the slide rod 35 are slidably sleeved. Two sets of symmetrically distributed second springs 36 are sleeved on the slide rod 35. The two ends of the second springs 36 are fixedly connected to the slide frame 34 and the mounting base 5, respectively. A locking block 37 is fixedly installed on the slide frame 34. A locking rod 38 is fixedly installed inside the mounting base 5. Two sets of symmetrically distributed locking brackets 39 are sleeved on the locking rod 38. The two sets of locking brackets 39 are movably locked with the locking block 37. Two sets of symmetrically distributed second torsion springs 40 are sleeved on the locking rod 38. The two ends of the second torsion springs 40 are fixedly connected to the locking brackets 39 and the locking rod 38, respectively. By installing the probe body 2 in the mounting tube 1, the outer shell of the probe body 2 and the outermost sleeve are made of nano-composite ceramic material. This material has high temperature resistance, strong corrosion resistance and stability, and can provide a good foundation for the internal transmission of the probe. The sensor and other structures are better protected. The mounting tube 1 has a mesh structure. Filling the gap between the mounting tube 1 and the mesh tube 3 with silicone particles can effectively protect the probe body 2 from moisture and moisture, preventing short circuits, component corrosion, or measurement errors caused by moisture, and improving reliability in high temperature and high humidity environments. When the slide 34 in the mounting base 5 slides and locks the locking block 37 between the two sets of locking brackets 39, the two sets of racks 33 slide synchronously with the slide 34. With the help of the third gear 32, the rotating rod 30 drives the pawl 29 to deflect, releasing the position restriction of the two sets of pawls 29 on the ratchet 28. The mounting shaft 26 can rotate freely. When the mounting shaft 26 rotates, it cooperates with multiple sets of second gears 27 and second gear rings 24 to achieve synchronous rotation of multiple sets of closed plates 25.The outer casing is then closed to seal the probe, preventing it from being impacted or corroded by dust. After all the closing plates 25 are closed, the positioning of the locking block 37 by the bracket 39 is released, allowing the pawl 29 to return to its original position and limiting the position of the corresponding ratchet 28. The mounting shaft 26 cannot rotate, and at this point, the closing plates 25 are stably in the closed state.

[0021] like Figure 4 As shown, an installation rod 6 is fixedly installed inside the installation tube 1. A first telescopic rod 7 is slidably installed inside the installation rod 6. A second telescopic rod 8 is slidably installed inside the first telescopic rod 7. A fixing ring 13 is fixedly installed at the end of the second telescopic rod 8 away from the installation rod 6. An installation ring 14 is provided inside the fixing ring 13. Four sets of symmetrically distributed damping rods 15 are provided between the fixing ring 13 and the installation ring 14. A first spring 16 is sleeved on the damping rod 15. The two ends of the damping rod 15 are fixedly connected to the installation ring 14 and the fixing ring 13, respectively. Multiple sets of annularly distributed positioning elements are provided inside the installation ring 14. The probe body 2 has a positioning groove 22 on the plate 19. Multiple positioning plates 19 are movably engaged with the probe body 2 through the positioning groove 22. A first rotating ring 17 is rotatably installed inside the mounting ring 14. A first toothed ring 18 is sleeved on the first rotating ring 17. Multiple positioning plates 19 are rotatably connected to the mounting base 5 through the positioning shaft 20. A first gear 21 is sleeved on each of the positioning shafts 20. The first gear 21 meshes with the first toothed ring 18. A screw 9 is rotatably installed inside the mounting rod 6. A screw tube 10 is rotatably installed inside the first telescopic rod 7. The screw 9 passes through the first telescopic rod 7. The retractable rod 7 is threadedly connected to the first telescopic rod 7. The screw tube 10 passes through the second telescopic rod 8 and is threadedly connected to the second telescopic rod 8. The screw rod 9 has two sets of symmetrically distributed keyways 11. The screw tube 10 has two sets of symmetrically distributed key blocks 12, which are distributed correspondingly to the keyways 11. The screw tube 10 is slidably sleeved with the screw rod 9 through the key blocks 12. During the rotation of the positioning shaft 20 driven by the motor in the mounting ring 14, the first gear 21 and the first gear ring 18 work together to realize the synchronous rotation of multiple positioning plates 19 on the mounting ring 14, changing the circumference between the multiple positioning plates 19. The circular diameter allows multiple positioning plates 19 to engage with or move away from the probe body 2 via positioning grooves 22, enabling quick installation or removal of the probe body 2 on the mounting ring 14. The motor in the mounting rod 6 drives the screw 9 to rotate, and under the limiting action of the key block 12 and keyway 11, it synchronously drives the screw tube 10, allowing the first telescopic rod 7 and the second telescopic rod 8 to slide in the mounting rod 6, thus enabling the probe body 2 to extend and retract within the mounting tube 1. This facilitates the use of the probe body 2 and also provides protection for it.

[0022] This utility model provides a high-temperature resistant shell structure for a lightweight temperature probe. The specific working principle is as follows: The probe body 2 is installed in the mounting tube 1. Both the outer shell of the probe body 2 and the outermost sleeve are made of nano-composite ceramic material. This material has ultra-high temperature resistance, strong corrosion resistance, and high stability, providing better protection for the sensor and other structures inside the probe. The mounting tube 1 has a mesh structure. Filling the gap between the mounting tube 1 and the mesh tube 3 with silica gel particles effectively achieves moisture-proof and moisture-absorbing protection for the probe body 2, preventing moisture absorption. To prevent probe short circuits, component corrosion, or measurement errors caused by moisture, and to improve reliability in high-temperature and high-humidity environments, when the slide 34 in the mounting base 5 slides to engage the locking block 37 between the two sets of locking brackets 39, the two sets of racks 33 slide synchronously with the slide 34. This, in conjunction with the third gear 32, causes the rotating rod 30 to deflect the pawl 29, releasing the positional constraint of the two sets of pawls 29 on the ratchet 28. The mounting shaft 26 can then rotate freely. During the rotation of the mounting shaft 26, multiple sets of second gears 27 and second gear rings 24 work together to achieve synchronous rotation of multiple sets of closed plates 25, thereby... The shell structure is closed to seal the probe, preventing it from being impacted or corroded by dust. After all the closing plates 25 are closed, the positioning of the locking block 37 by the bracket 39 is released, allowing the pawl 29 to return to its original position and limiting the position of the corresponding ratchet 28. The mounting shaft 26 cannot rotate. At this time, the closing plates 25 are stably in the closed state. During the rotation of the positioning shaft 20 driven by the motor in the mounting ring 14, the first gear 21 and the first gear ring 18 work together to achieve synchronous rotation of the multiple positioning plates 19 on the mounting ring 14, changing the arrangement of the multiple positioning plates 19. The size of the circular diameter allows multiple positioning plates 19 to engage with or move away from the probe body 2 via positioning grooves 22, enabling quick installation or removal of the probe body 2 on the mounting ring 14. The motor in the mounting rod 6 drives the screw 9 to rotate, and under the limiting action of the key block 12 and keyway 11, it synchronously drives the screw tube 10, allowing the first telescopic rod 7 and the second telescopic rod 8 to slide in the mounting rod 6, thus enabling the probe body 2 to extend and retract within the mounting tube 1. This facilitates the use of the probe body 2 and also provides protection for it.
