Description

Technical Field

[0001] The invention relates to the technical field of thermal resistance temperature measurement, in particular to a thermal resistance temperature measuring instrument. Background Art

[0002] Thermal resistors are the most commonly used temperature detectors in the medium and low temperature range. Thermal resistor temperature measurement is based on the characteristic that the resistance value of a metal conductor increases with the increase of temperature to measure temperature. Its main features are high measurement accuracy and stable performance. Among them, platinum thermal resistors have the highest measurement accuracy. They are not only widely used in industrial temperature measurement, but also made into standard reference instruments. Thermal resistors are mostly made of pure metal materials, with platinum and copper being the most commonly used. In addition, materials such as nickel, manganese and rhodium have begun to be used to manufacture thermal resistors. There are many types of temperature sensing materials commonly used in metal thermal resistors, and the most commonly used is platinum wire. In addition to platinum wire, metal thermal resistor materials for industrial measurement include copper, nickel, iron, iron-nickel, etc.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, an extended outer sheath is installed on the top of the bottom outer sheath, and an extended outer sheath can be further installed on the top of the extended outer sheath. The bottom outer sheath and the extended outer sheath together constitute the overall length of the probe. This means that the length of the probe of the temperature measuring instrument can be adjusted accordingly according to the actual use environment, and can be increased or deleted to match different temperature measurement depths. It is very flexible and convenient to use, and the connection adopts a threaded or magnetic connection, which is easy to assemble and disassemble and reuse.

[0017] 2. In the present invention, when installing the temperature measuring element and the extended outer sheath, the two half-sheath bodies are merged together, and the half-external thread block is screwed into the interior of the internal thread one for fixation, thereby achieving fixation. The installation principle of the upper and lower extended outer sheaths is consistent with the installation principle between the temperature measuring element and the extended outer sheath.

[0018] 3. In the present invention, after the two half-sheath bodies are merged, the cable is located between the two to form a stable cavity, and the connecting slots and the plug-in blocks on both sides are inserted into each other. At this time, the plug-in blocks will also squeeze the sealing layer, and then the elbow of the card block is inserted into the inside of the card slot, so as to quickly confine the base layers on both sides together, which is beneficial to prevent them from detaching after merging and facilitate their installation and use. In addition, the squeezing of the plug-in blocks and the sealing layer, as well as the staggered insertion of the plug-in blocks, are beneficial to improve the sealing of the two half-sheath bodies after merging, help prevent external liquids from penetrating from the gap, improve the sealing, and the provision of the titanium layer helps prevent erosion. The threaded installation method is stable and firm to prevent falling off.

[0019] 4. In the present invention, before installing the temperature measuring element and the extended outer sheath, the insulating ring and the extended insulating part can be fixed first. First, the two semicircular insulating sleeves are fixed by the magnetism of the vertical magnet and the vertical iron bar, and then the arc-shaped iron block at the bottom is magnetically fixed to the connecting magnet. Similarly, magnetic adsorption can be performed between the upper and lower extended insulating parts. At this time, the cable is located inside the insulating ring or the extended insulating part, thereby preventing the cable from being damaged and leaking, thereby improving the safety of use.

[0020] 5. In the present invention, when the cable is located in the inner cavity of the insulating ring or the extended insulating member, the cable will be located between the two insulating half rings. At this time, the position of the cable is limited to prevent it from moving around inside the cavity during use, which is beneficial to further improve the effect of anti-leakage insulation. In addition, the telescopic movement between the T-shaped column and the sleeve, as well as the elastic reset action of the spring, are also suitable for limiting cables of different sizes, so that it is adapted to different temperature measuring instruments.

[0021] 6. In the present invention, the rotating block moves vertically upward or downward under the transmission action of the threaded hole and the external thread thereon, and then fixes the temperature measuring head through the external thread. After the fixation is completed, the external air source allows the gas to enter the interior of the circular air bin through the air inlet pipe, and then enter the interior of the air cavity through the air inlet. When the gas inside the air cavity becomes more and more, the rubber layer expands and contacts the inner wall of the installation end, which not only realizes the single-point installation, but also improves the firmness of the single-point installation.

[0022] 7. The present invention may not adopt single-point threaded fixation. After fixing the crossbeam frame, select a vertical connecting strip of appropriate length and a fixing block for fixing, and fix the fixing block on the top slide. Then, fix the vertical connecting strip and the uppermost extended outer sheath through a T-column. Then, drive the motor to rotate the gear. Under the lateral transmission action of the gear and the rack, the bottom outer sheath can be driven to move, thereby realizing mobile multi-point temperature measurement, switching between single-point temperature measurement and multi-point temperature measurement, and realizing dual-purpose. The fixing ring slides on the bottom transverse slide rail through the slider, and the fixing ring is sleeved on the outer wall of the cable. At this time, when moving, the cable can be pulled and stored, which is beneficial to prevent the cable from getting entangled during movement and ensure its stability in use.

[0045] The working principle of the present invention is:

[0046] When in use, the extended outer sheath 15 is installed on the top of the bottom outer sheath 14, and the extended outer sheath 15 can be further installed on the top of the extended outer sheath 15. The bottom outer sheath 14 and the extended outer sheath 15 together constitute the overall length of the probe. This shows that the probe length of the temperature measuring instrument can be adjusted accordingly according to the actual use environment, and can be increased or deleted to match different temperature measurement depths. It is very flexible and convenient to use, and the connection adopts a threaded or magnetic connection, which is easy to assemble and disassemble and reuse.

[0047] When installing the temperature measuring element 13 and the extended outer sheath 15, after the two half-sheath bodies 36 are merged together, the half-external thread block 35 is screwed into the inner thread 29 to fix it, so as to fix it. The installation principle of the upper and lower extended outer sheaths 15 is consistent with the installation principle between the temperature measuring element 13 and the extended outer sheath 15. After the two half-sheath bodies 36 are merged, the cable 12 is located between the two to form a stable cavity, and the connecting slots 42 on both sides are inserted into the plug block 44. At this time, the plug block 44 will also seal The layer 43 is extruded, and then the elbow of the card block 45 is inserted into the inside of the card slot 48, so that the base layers 39 on both sides are quickly limited together, which is conducive to preventing them from being separated after being merged, and is convenient for installation and use. The extrusion of the plug block 44 and the sealing layer 43, as well as the staggered insertion of the plug blocks 44, are conducive to improving the sealing of the two half-sheath bodies 36 after being merged, which helps to prevent the external liquid from penetrating from the gap and improve the sealing. The setting of the titanium layer 40 helps to prevent erosion, and the threaded installation method is stable and firm to prevent falling off.

[0048] Before installing the temperature measuring element 13 and the extended outer sheath 15, the insulating ring 30 and the extended insulating member 37 can be fixed first. First, the two semicircular insulating sleeves 49 are fixed by the magnetism of the vertical magnet 52 and the vertical iron bar 51, and then the arc-shaped iron block 50 at the bottom is magnetically fixed to the connecting magnet 32. Similarly, the upper and lower extended insulating members 37 can also be magnetically adsorbed. At this time, the cable is located inside the insulating ring 30 or the extended insulating member 37, thereby preventing the cable 12 from being damaged and leaking electricity, thereby improving the safety of use;

[0049] When the cable 12 is located in the inner cavity of the insulating ring 30 or the extended insulating member 37, the cable will be located between the two insulating half rings 56. At this time, the position of the cable 12 is limited to prevent it from moving around inside the cavity when in use, which is conducive to further improving the effect of anti-leakage insulation. In addition, the telescopic movement between the T-shaped column 58 and the sleeve 59, as well as the elastic reset action of the spring 61, are also suitable for limiting the position of cables 12 of different sizes, so that it is adapted to different temperature measuring instruments;

[0050] The rotating block 22 is rotated under the transmission effect of the threaded hole and the external thread, so that the annular block A16 moves vertically upward or downward, and then the temperature measuring head is fixed by the external thread 18. After the fixing is completed, the external gas source allows the gas to enter the interior of the circular gas warehouse 21 through the air inlet pipe 23, and then enter the interior of the air cavity 26 through the air inlet 19. When the gas inside the air cavity 26 becomes more and more, the rubber layer 25 expands and contacts the inner wall of the installation end, which not only realizes the single-point installation, but also improves the firmness of the single-point installation.

[0051] Single-point threaded fixation may also be used instead. After fixing the crossbeam frame 5, a vertical connecting strip 67 of appropriate length is selected to fix it with the fixing block 62, and the fixing block 62 is fixed to the top slide plate 64. Then, the vertical connecting strip 67 is fixed to the topmost extended outer sheath 15 through the T-column 58. Then, the driving motor 63 drives the gear 66 to rotate. Under the lateral transmission action of the gear 66 and the rack 6, the bottom outer sheath 14 can be driven to move, thereby realizing mobile multi-point temperature measurement, switching between single-point temperature measurement and multi-point temperature measurement, and realizing dual-purpose. The fixing ring 11 slides on the bottom transverse slide rail 9 through the slider 10, and the fixing ring 11 is sleeved on the outer wall of the cable 12. At this time, when moving, the cable 12 is also pulled and stored, which is beneficial to prevent the cable 12 from getting entangled during the movement and ensure its stability in use.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
