Description

Technical Field

[0001] This utility model belongs to the field of temperature sensor technology, specifically relating to a high-temperature thermocouple surface temperature sensor. Background Technology

[0002] In existing technology, a temperature sensor refers to a sensor that can sense temperature and convert it into a usable output signal. Temperature sensors are the core component of temperature measuring instruments and come in a wide variety. They can be broadly classified into two categories based on the measurement method: contact and non-contact. Based on the characteristics of the sensor materials and electronic components, they are further divided into resistance temperature detectors (RTDs) and thermocouples.

[0003] Authorized publication number "CN222505639U" discloses a temperature sensor, including a base and a mounting end at the front end of the base. A cavity is formed within the mounting end, and a probe is fixedly mounted at the lower end of the cavity via a perforated bracket. The upper end of the probe extends into the cavity, and the lower end extends out of the perforated bracket. This invention, without increasing the sensor length, creates a medium space outside the probe, allowing for full contact between the probe and the measured medium, increasing effective heat transfer to the measured medium, and ensuring that the probe can respond quickly and effectively to changes in medium temperature.

[0004] The aforementioned novel probe can respond quickly and effectively to changes in medium temperature. However, its fixed and non-extendable structure makes it difficult to perform deep measurements in high-temperature or confined spaces, resulting in poor operational safety. Furthermore, operators must approach the high-temperature source for contact measurements, posing safety hazards such as burns. Overall, the poor operational safety limits its applicability and reliability in complex high-temperature environments. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature thermocouple surface temperature sensor, which aims to solve the problems of fixed and non-extendable probe structures in the prior art, making it difficult to perform in-depth measurements in high-temperature or confined spaces and resulting in poor operational safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A high-temperature detector includes a high-temperature detection sleeve, two rotating shafts, two rotating rods, two clamping grips, an expansion spring, a sensor fixing block, a sensor clamping groove, and a high-temperature environment detection head. The high-temperature detection sleeve is slidably connected between the lower end of the high-temperature detection handle and a fixed push plate. Both rotating shafts are fixedly connected to the inner circumferential wall of the fixed push plate. The two rotating rods are rotatably connected to the circumferential surfaces of the two rotating shafts. The two clamping grips are fixedly connected to the lower ends of the two rotating rods, with one side of each clamping grip fitting against the inner wall of the high-temperature detection sleeve. The expansion spring is fixedly connected to the adjacent ends of the two rotating rods. The sensor fixing block is slidably connected within the fixed push plate and the high-temperature detection sleeve. The sensor clamping groove is located on both sides of the sensor fixing block and matches the two clamping grips.

[0012] As a preferred embodiment of this utility model, the lower end of the high temperature detection handle is provided with a clamping push groove, the inner wall of the clamping grip is fixedly connected with the clamping push groove, and the upper end of the clamping spring groove and one side inner wall of the clamping push groove are fixedly connected with a clamping push spring.

[0013] As a preferred embodiment of this utility model, a connecting wire insertion groove is provided on one side of the high temperature detection handle and the fixed push plate, and the connecting wire insertion groove is used to place the data connection wire.

[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] Example

[0027] Please see Figures 1-4 The present invention provides the following technical solution:

[0028] A high-temperature thermocouple surface temperature sensor, comprising:

[0029] High temperature detection handle 1;

[0030] Fixed push plate 17 is fixedly connected to the lower end of high temperature detection handle 1;

[0031] The high-temperature detector includes a high-temperature detection sleeve 2, two rotating shafts 3, two rotating rods 4, two clamping grips 5, an expansion spring 6, a sensor fixing block 7, a sensor clamping groove 8, and a high-temperature environment detection head 9. The high-temperature detection sleeve 2 is slidably connected between the lower end of the high-temperature detection handle 1 and the fixed push plate 17. The two rotating shafts 3 are fixedly connected to the inner circumferential wall of the fixed push plate 17. The two rotating rods 4 are rotatably connected to the circumferential surfaces of the two rotating shafts 3, and the two clamping grips 5 are fixedly connected to the lower ends of the two rotating rods 4. One side of the two clamping grips 5 is in contact with the inner wall of the high-temperature detection sleeve 2. The expansion spring 6 is fixedly connected to the near ends of the two rotating rods 4. The sensor fixing block 7 is slidably connected to the fixed push plate 17 and the high-temperature detection sleeve 2. The sensor clamping groove 8 is opened on both sides of the sensor fixing block 7 and matches the two clamping grips 5.

[0032] In a specific embodiment of this utility model, the high-temperature detection sleeve 2 is slidably connected between the lower end of the high-temperature detection handle 1 and the fixed push plate 17, allowing the entire detector to be extended and retracted along the handle direction. Two rotating shafts 3 are respectively fixedly installed on the inner circumferential wall of the fixed push plate 17, serving as the rotation fulcrum of the rotating shaft rod 4. One end of the rotating shaft rod 4 is rotatably connected via the rotating shaft 3, and the other end is fixedly connected to the clamping gripper 5. The side of the clamping gripper 5 is tightly fitted with the inner wall of the high-temperature detection sleeve 2, thereby achieving adaptive adjustment of the sensor clamping position. An outward expansion spring 6 is disposed between the two rotating shaft rods 4, near the end, and its function is to provide outward expansion elasticity, allowing the clamping gripper 5 to automatically open and clamp the sensor fixing block 7. The sensor fixing block 7 is slidably disposed inside the fixed push plate 17 and the high-temperature detection sleeve 2, and has sensor clamping grooves 8 on both sides for cooperating with the clamping gripper 5 to achieve... The high-temperature environment probe 9 is clamped and fixed, installed at the front end of the sensor fixing block 7, and is used to directly contact the surface of the object being measured to collect temperature data under high-temperature conditions. In actual use, the user pulls the high-temperature probe sleeve 2 upward. At this time, the two fixed connection clamping claws 5 are no longer squeezed by the inner wall of the fixed connection clamping claws 5. The two fixed connection clamping claws 5 are expanded outward by the outward pushing force of the outward expansion spring 6. At this time, the sensor fixing block 7 is placed into the high-temperature probe sleeve 2. Then, the high-temperature probe sleeve 2 is reset. The inner wall of the high-temperature probe sleeve 2 squeezes the two fixed connection clamping claws 5 inward and closes them, clamping the sensor clamping groove 8, thereby completing the fixation of the probe. Since the high-temperature probe sleeve 2 and the high-temperature probe handle 1 can adjust the extension length of the probe according to the actual measurement needs, so that it can go deeper or further away from the high-temperature area, the operator can be effectively prevented from directly contacting the high-temperature environment, thus improving safety and measurement accuracy.

[0033] Please refer to the details. Figures 1-4 A limiting groove 10 is provided on the side end of the high temperature detection handle 1, and a limiting slider 11 is fixedly connected to the inner wall of the high temperature detection sleeve 2. The limiting slider 11 slides in the limiting groove 10.

[0034] In this embodiment: through the cooperation between the limiting slider 11 and the limiting groove 10, the high temperature detection sleeve 2 has a clear movement trajectory when sliding up and down along the high temperature detection handle 1, avoiding tilting or jamming due to uneven force, and limiting the sliding position of the high temperature detection sleeve 2 to prevent it from detaching.

[0035] Please refer to the details. Figures 1-4 The lower end of the high temperature detection handle 1 is provided with a clamping push groove 12. The inner wall of the clamping gripper 5 is fixedly connected with the clamping push groove 12. The upper end of the clamping spring groove 13 and the inner wall of one side of the clamping push groove 12 are fixedly connected with a clamping push spring 14.

[0036] In this embodiment: when the operator pushes the high-temperature detection sleeve 2 downward, it drives the clamping gripper 5 to move down along the clamping push groove 12. During this process, the clamping gripper 5 is mechanically limited and retracts inward, thereby opening the clamping opening and releasing the sensor fixing block 7. At this time, the clamping push spring 14 is compressed and stores elastic potential energy. When the high-temperature detection sleeve 2 is released, the clamping push spring 14 returns to its deformation and pushes the clamping gripper 5 outward to reset, so that it re-clamps the sensor fixing block 7, thus completing the stable fixation of the high-temperature environment detection head 9.

[0037] Please refer to the details. Figures 1-4 A connecting wire insertion groove 15 is provided on one side of the high temperature detection handle 1 and the fixed push plate 17. The connecting wire insertion groove 15 is used to place the data connection wire.

[0038] In this embodiment, by setting the connecting wire insertion groove 15 on the high temperature detection handle 1 and the fixed push plate 17, the originally exposed data connection wires can be neatly embedded into the groove, avoiding messy lines and improving the overall aesthetics and ease of operation of the device.

[0039] Please refer to the details. Figures 1-4 The lower end of the high temperature detection handle 1 is fixedly connected to a connecting line limiting cylinder 16, which is misaligned with the high temperature detector.

[0040] In this embodiment, by setting a connecting cable limiting cylinder 16, the data connecting cable is physically restricted before entering the device, thereby preventing the cable from swinging, bending or being subjected to uneven force, extending its service life and improving safety.

[0041] Please refer to the details. Figures 1-4 Both the high-temperature detection handle 1 and the high-temperature detection sleeve 2 are made of high-temperature resistant materials.

[0042] In this embodiment, the high-temperature detection handle 1 and the high-temperature detection sleeve 2 are made of glass fiber reinforced nylon, which avoids the structural failure problem caused by the softening, deformation or even melting of traditional plastic materials at high temperatures.

[0043] The working principle and usage process of this utility model are as follows: In actual use, the user pulls the high-temperature detection sleeve 2 upward. At this time, the two fixed connection clamping claws 5 are no longer squeezed by the inner wall of the fixed connection clamping claws 5. The two fixed connection clamping claws 5 expand outward by the outward pushing force of the outward expansion spring 6. At this time, the sensor fixing block 7 is placed into the high-temperature detection sleeve 2. Then, the high-temperature detection sleeve 2 is reset. The inner wall of the high-temperature detection sleeve 2 squeezes the two fixed connection clamping claws 5 inward to close, clamping the sensor clamping groove 8, thereby completing the fixation of the detection head. Since the high-temperature detection sleeve 2 and the high-temperature detection handle 1 can adjust the extension length of the detection head according to the actual measurement needs, so that it can go deeper or further away from the high-temperature area, the operator can be effectively prevented from directly contacting the high-temperature environment, thus improving safety and measurement accuracy.

[0044] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model 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 of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
