Description

Technical Field

[0001] This utility model relates to the field of temperature detection probe technology, and in particular to a high-strength waterproof temperature detection probe. Background Technology

[0002] In the field of temperature detection, temperature probes are widely used as important measurement tools in various industries, scientific research and daily life. However, existing temperature probes still have some obvious shortcomings in design and function, which to some extent limit their application range and performance.

[0003] In existing technologies, there is often significant resistance during probe insertion and removal, especially in applications requiring frequent probe insertion and removal, such as food processing and chemical production. The difficulty of probe insertion and removal not only increases the workload of operators but can also lead to probe damage or damage to the object being measured due to improper insertion or removal. Furthermore, insufficient probe stability within the measured object can easily cause fluctuations and errors in measurement results. Moreover, existing temperature detection probes have limitations in angle adjustment. Because the angle between the probe's temperature indicator block and the connecting rod is fixed, it cannot be flexibly adjusted according to actual needs. This limits the probe's versatility and flexibility to some extent. In some special applications, such as temperature measurement in confined spaces, fixed-angle probes cannot meet operational requirements.

[0004] Furthermore, we disclose a high-strength waterproof temperature detection probe to meet the practical needs of existing temperature detection probes in terms of ease of insertion and removal and flexibility of angle adjustment. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a high-strength waterproof temperature detection probe to solve the problems of insufficient insertion and removal smoothness and angle adjustment flexibility of the existing temperature detection probe.

[0006] To achieve the above objectives, this utility model provides a high-strength waterproof temperature detection probe, comprising a temperature-indicating block and a connecting rod. A connecting post is fixedly connected to the lower end of the temperature-indicating block, and a probe rod is fixedly connected to the lower end of the connecting rod. The lower end of the probe rod has a pointed design. A wire harness is fixedly connected to the upper end of the outer wall of the connecting rod, and the upper end of the wire harness is fixedly connected to the connecting post. Both ends of the wire harness are electrically connected to the temperature-indicating block and the probe rod, respectively. An expansion assembly is provided on the upper outer end of the probe rod to reduce the difficulty of pulling the probe rod out of the object being tested. An adjustment assembly is provided at the connection point between the upper end of the connecting rod and the connecting post to adjust the angle between the temperature-indicating block and the connecting rod.

[0007] Preferably, the expansion assembly includes multiple connecting plates, and the upper end of the outer wall of the probe rod is provided with multiple evenly spaced opening slots. The number of opening slots is the same as the number of connecting plates, and the lower end of the connecting plate is rotatably connected to the lower end of the opening slot.

[0008] Preferably, a telescopic spring is fixedly connected to the upper end of the inner side of the connecting plate, and the end of the telescopic spring away from the connecting plate is fixedly connected to the inner wall of the opening groove.

[0009] Preferably, the adjusting assembly includes a rotating seat fixedly connected to the upper end of the connecting rod, a rotating plate rotatably connected inside the rotating seat, the upper end of the rotating plate being fixedly connected to the connecting column, an insert rod slidably connected to one side of the rotating seat, an annular plate fixedly connected to one side of the outer wall of the insert rod, a return spring fixedly connected to the outer side of the annular plate near the rotating seat, the end of the return spring away from the annular plate being fixedly connected to the rotating seat, and the return spring being sleeved on the outside of the insert rod.

[0010] Preferably, a plurality of insertion holes are evenly spaced on the outer side of the rotating plate, and the end of the insertion rod away from the ring plate is slidably connected to the inside of the insertion hole.

[0011] Preferably, a support base is fixedly connected to the lower end of one side face of the rotating seat, and a pressure plate is rotatably connected to one end of the support base. A sliding groove is provided on one side of the pressure plate near the insertion rod, and a slider is slidably connected inside the sliding groove. The lower end of the slider is rotatably connected to one end of the insertion rod through a ball head.

[0012] Preferably, the connection between the probe rod and the connecting rod is formed by riveting.

[0013] The beneficial effects of this utility model are:

[0014] 1. This high-strength waterproof temperature detection probe features an expansion assembly. Through the flexible rotation of multiple connecting plates outside the probe rod, and the elastic force of the telescopic springs, the connecting plates retract inwards to accommodate the insertion process and reduce insertion resistance when the probe rod is inserted into the object being tested. Conversely, when the probe rod needs to be pulled outwards, the connecting plates expand outwards through the telescopic springs, fitting snugly against the inner wall of the object being tested. This design not only enhances the stability of the probe rod within the object being tested, preventing loosening or detachment due to external factors, but also cleverly utilizes the expansion force of the connecting plates to assist in the removal of the probe rod, reducing the difficulty of removal and improving the efficiency of the testing process. Especially in applications requiring frequent probe insertion and removal, the expansion assembly significantly reduces operational difficulty and time costs, while also ensuring the accuracy and reliability of the probe.

[0015] 2. This high-strength waterproof temperature detection probe is equipped with an adjustment component, allowing the angle between the temperature indicator block and the connecting rod to be flexibly adjusted according to actual needs. Through the coordinated action of the rotating plate, insertion rod, and return spring inside the rotating base, users can easily adjust the angle of the temperature indicator block to adapt to different detection requirements and operating environments. This design not only improves the probe's versatility and flexibility but also makes operation more convenient and comfortable, reducing the labor intensity of operators and improving work efficiency. At the same time, the stability and reliability of the adjustment component ensure that the probe maintains stable performance during long-term use. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0025] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0026] like Figures 1 to 5 As shown, a high-strength waterproof temperature detection probe includes a temperature indicator block 1 and a connecting rod 4. A connecting post 2 is fixedly connected to the lower end of the temperature indicator block 1, and a probe rod 6 is fixedly connected to the lower end of the connecting rod 4. The lower end of the probe rod 6 has a pointed design. A wire harness 7 is fixedly connected to the upper end of the outer wall of the connecting rod 4. The upper end of the wire harness 7 is fixedly connected to the connecting post 2, and both ends of the wire harness 7 are electrically connected to the temperature indicator block 1 and the probe rod 6, respectively. An expansion component is provided on the upper outer end of the probe rod 6. The expansion component is used to reduce the difficulty of pulling the probe rod 6 out of the object being tested. An adjustment component is provided at the connection between the upper end of the connecting rod 4 and the connecting post 2. The adjustment component is used to adjust the angle between the temperature indicator block 1 and the connecting rod 4.

[0027] The temperature detection probe rod 6 is made of waterproof material, ensuring stable performance even in extreme environments such as humidity, underwater, and high pressure or high temperature. It effectively prevents moisture intrusion and extends service life. Its unique expansion component design allows the probe rod 6 to easily overcome resistance when inserted into the object being measured. At the same time, when pulled out, the connecting plate 9 expands outward through the action of the telescopic spring 10, closely adhering to the inner wall of the object being measured. This ensures measurement accuracy, reduces operational difficulty, and minimizes the risk of damage to the probe rod 6 and the object being measured. In addition, the probe rod 6 has an adjustable angle function. Through the adjustment component, users can easily adjust the angle between the temperature indicator block 1 and the connecting rod 4 to adapt to different measurement needs and operating environments, greatly improving the versatility and flexibility of the probe rod 6.

[0028] Furthermore, such as Figure 2As shown, the expansion assembly includes multiple connecting plates 9. Multiple opening slots 8 are evenly spaced on the upper end of the outer wall of the probe rod 6. The number of opening slots 8 is the same as the number of connecting plates 9. The lower end of the connecting plate 9 is rotatably connected to the lower end of the opening slot 8. A telescopic spring 10 is fixedly connected to the upper end of the inner side of the connecting plate 9. The end of the telescopic spring 10 away from the connecting plate 9 is fixedly connected to the inner wall of the opening slot 8.

[0029] When the probe rod 6 is inserted into the object being measured, the multiple connecting plates 9 are compressed inward by the inner wall of the object being measured. At this time, the telescopic spring 10 is compressed and stores energy. Once the probe rod 6 begins to be pulled out, the telescopic spring 10 releases energy and pushes the connecting plates 9 to expand outward and fit tightly against the inner wall of the object being measured. This design not only helps to stabilize the probe rod 6 and prevent it from loosening or falling off during the pulling process, but also uses the friction between the connecting plates 9 and the object being measured to assist the smooth pulling out of the probe rod 6, thus achieving a smooth and stable insertion and removal process.

[0030] Furthermore, such as Figure 1 , Figures 3 to 5 As shown, the adjusting assembly includes a rotating seat 3 fixedly connected to the upper end of the connecting rod 4. A rotating plate 5 is rotatably connected inside the rotating seat 3. The upper end of the rotating plate 5 is fixedly connected to the connecting column 2. A plug rod 12 is slidably connected to one side of the rotating seat 3. A ring plate 13 is fixedly connected to one side of the outer wall of the plug rod 12. A return spring 14 is fixedly connected to the outer side of the ring plate 13 near the rotating seat 3. The end of the return spring 14 away from the ring plate 13 is fixedly connected to the rotating seat 3, and the return spring 14 is sleeved on the outside of the plug rod 12. The outer side of the rotating plate 5... Multiple insertion holes 15 are evenly spaced on the side. The end of the insertion rod 12 away from the ring plate 13 is slidably connected to the inside of the insertion hole 15. A support base 16 is fixedly connected to the lower end of one side end face of the rotating seat 3. A pressure plate 11 is rotatably connected to one end of the support base 16. A sliding groove 17 is opened on the side end face of the pressure plate 11 near the insertion rod 12. A slider 18 is slidably connected inside the sliding groove 17. The lower end of the slider 18 is engaged and rotatably connected to one end of the insertion rod 12 through a ball head. The connection between the probe rod 6 and the connecting rod 4 is formed by riveting.

[0031] By rotating the rotating seat 3 connected to the upper end of the connecting rod 4, the internal rotating plate 5 can rotate freely relative to the rotating seat 3. The upper end of the rotating plate 5 is fixedly connected to the connecting column 2, thus achieving preliminary adjustability of the angle between the temperature indicator block 1 and the connecting rod 4. To fix the rotating plate 5 at the required angle, the insertion rod 12 on one side of the rotating seat 3 can be inserted into the corresponding insertion hole 15 on the rotating plate 5 under the action of the return spring 14, thereby locking the angle. The outer wall of the insertion rod 12 is connected to the rotating seat 3 through the ring plate 13 and the return spring 14, ensuring that the insertion rod 12 can move stably and flexibly. In addition, the pressure plate 11 rotatably connected to the support base 16 on one side of the rotating seat 3 cooperates with the slider 18 through the sliding groove 17 opened on it. The lower end of the slider 18 is engaged and rotatably connected to the insertion rod 12 in the form of a ball head. This design allows the user to overcome the elastic force of the return spring 14 by pressing the pressure plate 11, so that the insertion rod 12 can be withdrawn from the insertion hole 15, thereby unlocking the angle of the rotating plate 5 and facilitating new angle adjustment. The whole adjustment process is simple and quick. Moreover, the connection between the probe rod 6 and the connecting rod 4 formed by the riveting process ensures the structural strength and connection reliability of the probe rod 6.
