It is a widely used detection device in industrial production, such as furnace combustion monitoring and intelligent combustion control. Common temperature detection instruments include bimetallic thermometers, thermocouples, resistance thermometers, and radiation thermometers. Existing thermocouple-type temperature detectors still have certain defects in use, such as...

[0003] Currently used thermocouple-type temperature detectors rely on a metal disc connected to the outside of the temperature detector's protective tube. The detector is then fixed to industrial production equipment by bolts passing through the metal disc and threaded holes in the support surface. Disassembly requires the use of an electric screwdriver or wrench to unscrew multiple sets of bolts in sequence to remove the temperature detector, making replacement difficult. Furthermore, when the internal sensor needs to be inspected, the protective tube must be removed, making maintenance inconvenient. Utility Model Content

[0025] 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.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a temperature detector that is easy to replace, comprising: a junction box 1, a transmitter module 2, a high-frequency ceramic tube 3, and a sensor 4;

[0027] A transmitter module 2 is installed inside the junction box 1, and the junction box 1 serves as the connection base. A high-frequency ceramic tube 3 is installed below the transmitter module 2. A sensor 4 is connected to the end of the high-frequency ceramic tube 3. Both the high-frequency ceramic tube 3 and the sensor 4 are installed inside the protection mechanism 5. The protection mechanism 5 is connected to the bottom of the junction box 1. A docking mechanism 6 is connected to the outer circumference of the protection mechanism 5. An installation plate 7 is installed below the docking mechanism 6.

[0028] The protection mechanism 5 includes: a U-shaped frame 501, a bearing 502, a rotating shaft 503, a handle 504, a bidirectional threaded rod 505, an arc plate 506, a semi-circular protective tube 507, a guide seat 508, and a guide rod 509. The U-shaped frame 501 is connected below the junction box 1, and a high-frequency ceramic tube 3 is connected through the U-shaped frame 501. When it is necessary to inspect the internal components, the handle 504 is manually rotated counterclockwise. At the same time, the handle 504 drives the bidirectional threaded rod 505 to rotate, and the two sets of arc plates 506 drive the two sets of semi-circular protective tubes 507 to move to both sides at the same time, thereby opening the protection mechanism 5 and exposing the internal components, which facilitates inspection.

[0029] A bearing 502 is connected to the inner wall of the loop frame 501. A rotating shaft 503 is connected inside the bearing 502. A handle 504 is connected to one end of the rotating shaft 503. The end of the handle 504 is connected through to one side of the loop frame 501. By rotating the external handle 504, the internal double-threaded rod 505 can be rotated. A double-threaded rod 505 is connected to one end of the rotating shaft 503. An arc-shaped plate 506 is threaded onto the double-threaded rod 505. A semi-circular protective tube 507 is connected below the arc-shaped plate 506. When the two sets of arc-shaped plates 506 move outward, they can drive the two sets of semi-circular protective tubes 507 to move simultaneously. A guide seat 508 is connected above the arc plate 506, and a guide rod 509 is connected through the guide seat 508. The end of the guide rod 509 is connected to the inner side wall of the loop frame 501. The guide seat 508 and the guide rod 509 restrict the arc plate 506, so that the arc plate 506 can move in the direction of rotation of the bidirectional threaded rod 505.

[0030] The docking mechanism 6 includes: a docking plate 601, a docking groove 602, a through hole 603, a circular groove 604, a through hole 605, a T-shaped rod 606, a torsion spring 607, a placement cavity 608, a T-shaped plate 609, a rectangular groove 610, and a circular cavity 611. The docking plate 601 is connected to one side of the semi-circular protective tube 507. The docking plate 601 is engaged in the docking groove 602. A through hole 603 is provided at the bottom of the docking groove 602. The semi-circular protective tube 507 is connected through the through hole 603. When the temperature detector needs to be replaced, the T-shaped rod 606 is manually rotated 90°. The T-shaped rod 606 drives the T-shaped plate 609 to rotate 90° as well. Then, the docking plate 601 is pulled upward to remove the temperature detector, which facilitates replacement.

[0031] A circular groove 604 is formed on the upper surface of the docking plate 601, and a through hole 605 is formed at the bottom of the circular groove 604. A T-shaped rod 606 is connected through the through hole 605, and the end of the T-shaped rod 606 is set in the circular groove 604. A torsion spring 607 is connected to the outer circumferential surface of the T-shaped rod 606, and the end of the torsion spring 607 is connected to the inner wall of the placement cavity 608. The placement cavity 608 is formed on the inner circumferential surface of the through hole 605. Through the torsion spring 607, the T-shaped rod 606 can drive the T-shaped plate 609 to reset itself after losing external torque.

[0032] The end of the T-shaped rod 606 is connected to a T-shaped plate 609. The T-shaped plate 609 passes through the rectangular groove 610 and engages with the circular cavity 611. The rectangular groove 610 is located at the bottom of the docking groove 602, and the circular cavity 611 is located inside the rectangular groove 610. The arc plate 506, the semi-circular protective tube 507, and the docking plate 601 are symmetrically arranged in two sets about the central axis of the bidirectional threaded rod 505. The high-frequency ceramic tube 3 and the sensor 4 are arranged between the two sets of semi-circular protective tubes 507, so that the docking mechanism 6 will not affect the normal use of the protection mechanism 5.

[0033] In conclusion: Figure 1-5As shown, when using this easily replaceable temperature detector, a simple understanding of the device is provided. First, manually rotate the T-shaped rods 606 inside the two sets of mating plates 601 by 90°. The T-shaped rods 606 drive the T-shaped plates 609 to rotate, simultaneously twisting the torsion springs 607. Then, insert the two sets of mating plates 601 into the mating grooves 602. After the bottom of the mating plates 601 contacts the bottom surface of the mating grooves 602, the rotated T-shaped plates 609 penetrate the rectangular grooves 610 and enter the circular cavity 611. Open the T-shaped rod 606. Under the action of the torsion spring 607, the T-shaped rod 606 drives the T-shaped plate 609 to reset. After the T-shaped plate 609 is fully reset, it cannot be pulled out from the rectangular slot 610, thus installing the temperature detector in the mounting plate 7. Then, contact the mounting plate 7 with the equipment support surface and fix the mounting plate 7 with the through bolts, thereby installing the temperature detector on the equipment. When replacement is needed, manually rotate the two sets of T-shaped rods 606 by 90° again to pull out the docking plate 601 and remove it. The temperature detector is installed using the same method. No bolts need to be unscrewed or the mounting plate 7 removed before the temperature detector can be removed from the equipment, facilitating replacement. Secondly, when it is necessary to inspect components such as sensor 4, remove the temperature detector and manually rotate handle 504 counterclockwise. Handle 504 drives the bidirectional threaded rod 505 to rotate via shaft 503. Since the bidirectional threaded rod 505 is threadedly connected to two sets of arc plates 506, and the two sets of arc plates 506 are slidably connected to guide rod 509 via corresponding guide seats 508, when the bidirectional threaded rod 505 rotates counterclockwise, the two sets of arc plates 506 can simultaneously move the two sets of semi-circular protective tubes 507 to both sides, thereby opening the protective mechanism 5 and exposing the internal components such as sensor 4 and high-frequency ceramic tube 3. It is not necessary to remove the entire protective tube, thus facilitating the inspection and maintenance of components such as sensor 4 and high-frequency ceramic tube 3. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0034] Although the present invention 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 technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
