Description

Technical Field

[0001] This utility model belongs to the field of instrument sensor technology, and specifically relates to an instrument sensor probe. Background Technology

[0002] A sensor is a device that can sense the external environment or system state and convert these physical quantities (such as temperature, pressure, humidity, light intensity, sound, etc.), chemical quantities, or biological quantities into electrical signals, optical signals, etc. A probe, as part of a sensor or a device closely integrated with it, mainly functions to transmit the signal to be measured to the measuring instrument without distortion and reliably for measurement. Probes and sensors together constitute an important part of modern instruments and meters, and are widely used in many fields such as industrial automation, environmental monitoring, medical equipment, automotive industry, aerospace, and energy management. For example, the existing patent with publication number CN209727310U discloses "a high-sensitivity measuring sensor for instruments, including a meter head, a support rod, a probe, and a mounting base. The meter head and the probe are respectively installed at the upper and lower ends of the support rod. The probe is connected to the meter head through a wire. The structure of the probe includes a stainless steel shell and a temperature measuring element set in the stainless steel shell." It can be seen that the probe described in this application is a common instrument sensor probe, which is generally installed above pipes or channels.

[0003] In practical use, most existing instrument sensor probes are directly fixed to the mounting base above the pipe using threads. However, due to the lack of a well-designed protective structure at the connection point, the connection between the probe and the mounting base is exposed to the outside for a long time, which may be damaged or loosened by impacts from foreign objects. This reduces the installation stability and operational stability of the entire sensor probe. Therefore, this utility model aims to improve and optimize the existing instrument sensor probe to solve this problem. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] Example 1

[0024] Please see Figures 1 to 4This is the first embodiment of the present invention, which provides a technical solution: an instrument sensor probe, comprising...

[0025] The sensor probe 1 is installed on the top of the base pipe 4, the probe seat 2 is welded and fixed to the top of the sensor probe 1, the cylinder 3 is welded and fixed to the top of the probe seat 2, the instrument 6 is installed on the top of the cylinder 3, the mounting base 41 is welded and fixed to the top surface of the base pipe 4, and the circular threaded seat 42 is welded and fixed to the top of the mounting base 41. The bottom end of the sensor probe 1 penetrates to the inside of the base pipe 4 and is threadedly connected to the circular threaded seat 42. The specific model of the sensor probe 1 can be NTC10K. The above structural principles are all technologies that have been disclosed in the prior art. For details, please refer to the existing patent with publication number CN209727310U. It will not be elaborated here.

[0026] The system includes a protective mechanism, comprising an annular base cylinder 51 that slides on the surface of the cylindrical column 3, an annular protective cylinder 52 that is welded and fixed to the bottom surface of the annular base cylinder 51, an annular enclosure 43 that is welded and fixed to the top of the mounting base 41 and corresponds to the annular protective cylinder 52, and a disassembly and assembly structure 53 set between the annular base cylinder 51 and the annular enclosure 43. After the sensor probe 1 has been installed by conventional locking, the annular base cylinder 51 slides down, causing the annular protective cylinder 52 to be inserted into the inner side of the annular enclosure 43, thereby completely enclosing the sensor probe 1, probe seat 2, circular threaded seat 42 and other structures inside, providing effective protection and preventing damage caused by accidental impact from foreign objects.

[0027] In this embodiment, preferably, the disassembly and assembly structure 53 includes a cylindrical movable groove 535 opened in the annular base cylinder 51, a cylindrical movable block 536 and a spring 537 installed in the cylindrical movable groove 535, a cylindrical movable rod 531 fixed to the side of the cylindrical movable block 536 and extending to the outer surface of the annular base cylinder 51, a side locking plate 532 fixed to the outer end surface of the cylindrical movable rod 531, a triangular locking block 533 fixed to the surface of the annular enclosure 43 and corresponding to the side locking plate 532, and a rectangular locking hole 534 opened on the bottom surface of the side locking plate 532 and adapted to the triangular locking block 533. In actual use, after the sensor probe 1 is successfully installed by threading and locking with the circular threaded seat 42, the annular base cylinder 51 can be slid down to the bottom of the cylinder 3 and fit against the probe seat 2. Insert the bottom end of the annular casing 52 into the inside of the annular enclosure 43, and move the bottom end of the side clamping plate 532 down to one side of the annular enclosure 43, so that the triangular clamping block 533 can be inserted into the rectangular clamping hole 534. This completes the locking and limiting of the annular base cylinder 51 and the annular casing 52 after they slide down. When the sensor probe 1 needs to be disassembled and maintained laterally, first pull the side clamping plate 532 to the side, so that the cylindrical movable rod 531 slides sideways with the cylindrical movable block 536, and the spring 537 is gradually compressed until the side clamping plate 532 separates from the triangular clamping block 533. Then the annular casing 52 and the annular base cylinder 51 are no longer limited. At this time, the annular base cylinder 51 can be slid up to the top of the cylinder column 3, so that the sensor probe 1, the probe seat 2 and the circular threaded seat 42 are exposed, and normal disassembly and maintenance can be performed.

[0028] In this embodiment, preferably, one end of the spring 537 abuts against the side of the cylindrical movable block 536, and the other end of the spring 537 abuts against the inner wall of the cylindrical movable groove 535.

[0029] In this embodiment, preferably, the cylindrical movable rod 531 passes through the inside of the spring 537, so that the cylindrical movable rod 531 does not affect the normal extension and contraction of the spring 537.

[0030] In this embodiment, preferably, the surface of the annular base cylinder 51 is symmetrically provided with two through holes that are adapted to the cylindrical movable rod 531, and the through holes communicate with the cylindrical movable groove 535 to allow the cylindrical movable rod 531 to pass through smoothly.

[0031] In this embodiment, preferably, the top two sides of the sensor probe 1 are welded and fixed with supporting reinforcing ribs 11, and the bottom end of the supporting reinforcing ribs 11 is in contact with the circular threaded seat 42, which can play a certain role in strengthening the top of the sensor probe 1 and further ensure the installation stability of the sensor probe 1.

[0032] Example 2

[0033] Please see Figures 1 to 5This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that an effective seal can be achieved between the annular enclosure 43 and the annular protective cylinder 52 through the provided sealing structure.

[0034] Specifically, the protective mechanism also includes a sealing structure, which is set between the annular casing 52 and the annular enclosure 43.

[0035] In this embodiment, preferably, the sealing structure includes a sealing ring 54 glued to the surface of the annular sleeve 52, and the bottom end of the sealing ring 54 is in contact with the top surface of the annular enclosure 43. The bottom surface of the sealing ring 54 is provided with an integral annular rubber ring 541. Both are made of rubber and will undergo elastic deformation when squeezed. The top surface of the annular enclosure 43 is provided with an annular sealing groove 431 corresponding to the annular rubber ring 541. The annular rubber ring 541 is embedded in the annular sealing groove 431, which can form an annular seal between the annular enclosure 43 and the annular sleeve 52 to prevent the infiltration of external water stains.

[0036] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
