Description

Technical Field

[0001] This utility model relates to the field of thermometer technology, specifically to a movable and adjustable thermocouple thermometer. Background Technology

[0002] A thermocouple thermometer is a temperature measuring instrument based on the thermoelectric effect. It consists of a thermocouple (temperature sensing element), a measuring instrument, and connecting wires. Thermocouple thermometers have the advantages of simple structure, wide measuring range, convenient use, and accurate and reliable temperature measurement, and are widely used in industrial production.

[0003] Chinese patent CN222013343U discloses an industrial thermocouple thermometer, comprising: a junction box, wherein a side connector is provided on the side wall of the junction box and a protective tube is detachably provided at the bottom; a thermocouple, wherein the thermocouple is disposed in the protective tube for detecting temperature; and a sound-absorbing structure, wherein the sound-absorbing structure is sleeved on the protective tube and is detachably provided; wherein the sound-absorbing structure is telescopic.

[0004] Although the aforementioned thermocouple thermometer achieves the effect of reducing the impact of noise on the thermocouple and improving measurement accuracy through sound-absorbing structure, in actual temperature measurement, such as when measuring the temperature of liquid in a reaction vessel, the liquid temperature distribution may not be uniform, and the liquid temperature at different depths may be different. Measuring the temperature at a single location will lead to inaccurate and unrepresentative temperature data. Therefore, we propose a movable and adjustable thermocouple thermometer. Utility Model Content

[0005] The purpose of this invention is to provide a movable and adjustable thermocouple thermometer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a movable and adjustable thermocouple thermometer, comprising a thermocouple thermometer body, a display screen mounted on the surface of the thermocouple thermometer body, and control buttons mounted on the surface of the thermocouple thermometer body below the display screen. An outer shell is fixed to the outside of the thermocouple thermometer body, and a dovetail groove is provided on the inner wall of the outer shell. A toothed plate is slidably connected inside the dovetail groove. A support plate is fixed to one side of the bottom end of the toothed plate, and a temperature probe is mounted on the bottom end of the support plate. A spring wire is mounted on the bottom end of the thermocouple thermometer body, and the bottom end of the spring wire passes through the support plate and connects to the temperature probe. A pulsator is mounted on the outer wall of the bottom of the outer shell, and a gear is mounted on one side of the pulsator, and the gear meshes tightly with the toothed plate.

[0007] Preferably, the toothed plate is a long strip structure with toothed grooves on one side, and both sides of the toothed plate extend into the interior of the dovetail groove.

[0008] Preferably, a support is fixed on the outer wall of the housing on one side of the gear, and a limit groove is provided on the two inner walls of the support.

[0009] Preferably, the support has a push block inside, with both sides of the push block extending into the interior of the limiting groove, and one end of the push block extending to the outside of the support and fixed with a positioning rod, the positioning rod cooperating with the gear.

[0010] Preferably, the outer casing has an H-shaped structure, and the outer casing is connected to the thermocouple thermometer body by bolts.

[0011] Preferably, a handle is fixed to the top of the outer shell, and the handle has an arc-shaped structure.

[0012] Preferably, an indicator is fixed to one side of the top of the toothed plate, and the indicator is located on one side of the surface of the thermocouple thermometer body.

[0013] Preferably, the outer wall on one side of the housing is marked with scale lines, and the scale lines cooperate with the indicator.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By holding the thermocouple thermometer body and inserting the temperature probe into the liquid in the reactor, the impeller is turned to rotate the gear, which drives the toothed plate to move down along the dovetail groove. The toothed plate, through the support plate, moves the temperature probe down, stretching the spring wire. By extending the temperature probe to different lengths, the probe can be inserted into the liquid at different depths, thus measuring the temperature at different depths. This design allows the temperature probe to be moved and adjusted, thereby improving the accuracy and representativeness of the temperature measurement, and better meeting the needs of practical applications.

[0016] The toothed plate moves the indicator synchronously. By using the indicator and comparing it with the scale lines, the extension length of the temperature probe can be precisely controlled, making it easy to record the temperature measurement position.

[0017] By pushing the push block to move it out of the limiting slide, the push block drives the positioning rod to extend and engage in the corresponding tooth groove of the gear. By locking the gear, the position of the tooth plate can be locked, thereby locking the position of the temperature probe, which allows the temperature probe to stay in the liquid for a moment and ensures the accuracy of temperature measurement.

The thermocouple thermometer body 1 is located at the port of the reaction vessel. The temperature probe 8 transmits the thermoelectric potential signal to the thermocouple thermometer body 1 through the spring wire 9. The measured temperature is displayed on the display screen 2.

[0029] The toothed plate 6 is a long strip structure with toothed grooves on one side, and both sides of the toothed plate 6 extend into the interior of the dovetail groove 5.

[0030] Specifically, turning the impeller 10 causes the gear 11 to rotate, and the gear 11 drives the toothed plate 6 to move down along the dovetail groove 5. The toothed plate 6 drives the temperature probe 8 to move down through the support plate 7, stretching the spring wire 9. By extending the temperature probe 8 to different lengths, the temperature probe 8 can be inserted into the liquid at different depths, thus measuring the temperature at different depths of the liquid. This design allows the temperature probe 8 to be movable and adjustable, thereby improving the accuracy and representativeness of temperature measurement, and better meeting the needs of practical applications.

[0031] A support 12 is fixed on the outer wall of the outer casing 4 on one side of the gear 11, and a limit groove 13 is provided on the two inner walls of the support 12;

[0032] The support 12 is provided with a push block 14 inside.

By locking the gear 11, the position of the tooth plate 6 can be locked, thereby locking the position of the temperature probe 8, which makes it easy for the temperature probe 8 to stay in the liquid for a moment, ensuring the accuracy of temperature measurement.

[0039] In this embodiment, the following steps are taken: First, the thermocouple thermometer body 1 is held in hand, and the temperature probe 8 is inserted into the liquid in the reaction vessel. The thermocouple thermometer body 1 is located at the port of the reaction vessel. The temperature probe 8 transmits the thermoelectric potential signal to the thermocouple thermometer body 1 through the spring wire 9. The measured temperature is displayed on the display screen 2.
