Description

Technical Field

[0001] This utility model belongs to the field of sensor technology, specifically a sensor device. Background Technology

[0002] NTC temperature sensors are thermistors or probes that work on the principle that resistance decreases rapidly as temperature rises. They are typically composed of various metal oxides mixed in a fluid-like clay and sintered in a high-temperature furnace to form a dense sintered ceramic. Their actual size is very flexible, ranging from very small diameters to almost unlimited maximum sizes.

[0003] Existing NTC temperature sensor devices lack flexible, movable components. Once the device is installed in a predetermined position, the NTC sensor element cannot be moved. This limits the device to collecting temperature information from only a specific area. Furthermore, since the sensor is typically mounted on the side wall of a structure, far from the center, it can easily lead to inaccurate temperature measurements.

[0004] Therefore, this utility model provides a sensor device. Utility Model Content

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5 As shown, a sensor device according to an embodiment of the present invention includes an NTC sensor 1 and a threaded housing 11. A threaded cylinder 12 is threadedly connected to the end of the threaded housing 11. A fixing rod 13 is fixedly connected to the side wall of the threaded cylinder 12, and two fixing rods 13 are symmetrically arranged. A fixing plate 14 is slidably connected to the side wall of the fixing rod 13. Fixing screw holes 15 are provided on the side wall of the fixing plate 14, and multiple fixing screw holes 15 are correspondingly arranged. Limiting rings 16 are respectively provided on the side wall of the fixing rod 13. An operating handle 17 is fixedly connected between two limiting rings 16. During operation, the operator can use the fixing screw holes 15 to install the fixing plate 14 in a predetermined position, wherein the two limiting rings 16 are respectively provided on the side wall of the fixing rod 13. The threaded cylinder 12 and the fixed plate 14 are fixedly connected by an operating handle 17. The operator can push the fixed rod 13 through the operating handle 17 to adjust the relative position of the threaded cylinder 12 and the fixed plate 14. When the threaded cylinder 12 moves, the threaded shell 11 will move synchronously. With the movement of the threaded shell 11, the end of the NTC sensor 1 will also move. Finally, the operator can adjust the end of the NTC sensor 1 to the predetermined position. Through the above structure, the limiting ring 16 and the operating handle 17 push the fixed rod 13, thereby causing the threaded cylinder 12 and the threaded shell 11 to move, and finally transporting the NTC sensor 1 to the predetermined position. This improves the flexibility of the sensor and helps to solve the problem of the NTC sensor 1 being inconvenient to move.

[0026] like Figure 3 and Figure 4As shown, a first heat-shrinkable sleeve 2 is provided on the side wall of the NTC sensor 1; a rotating groove 21 is provided on the inner side wall of the threaded shell 11, and the two rotating grooves 21 are arranged correspondingly; clamping blocks 22 are rotatably connected to the side walls of the two rotating grooves 21 respectively; an auxiliary groove 23 is provided on the side wall of the clamping block 22; a limiting sleeve 24 is provided on the side wall of the threaded shell 11, and the limiting sleeve 24 is set according to the size of the threaded shell 11; during operation, whenever it is necessary to fix the end of the NTC sensor 1 to the threaded shell 11, the operator can first insert the NTC sensor 1 with the first heat-shrinkable sleeve 2 installed into the threaded shell 11, and then the operator can rotate the two clamping blocks 22 respectively until the two clamping blocks are fixed. Block 22 simultaneously contacts the side wall of the first heat shrink tubing 2. Finally, the operator can put the limiting sleeve 24 on the side wall of the threaded shell 11 to fix the position of the clamping block 22. The rotating groove 21 is set to correspond to the range of motion of the clamping block 22, and the clamping block 22 can rotate 90 degrees. The operator can adjust the position of the clamping block 22 with the help of the auxiliary groove 23. Through the above structure, the rotatable clamping block 22 clamps the first heat shrink tubing 2, thereby restricting the position of the NTC sensor 1, improving the flexibility of the sensor device, facilitating the convenient replacement of the NTC sensor 1, reducing the maintenance difficulty of the sensor device, and improving work efficiency.

[0027] like Figures 1 to 4 As shown, a sealing port 3 is fixedly connected inside the threaded shell 11, and the sealing port 3 is sized to correspond to the first heat shrink sleeve 2. A second heat shrink sleeve 31 is provided between the sealing port 3 and the NTC sensor 1. During operation, the sealing port 3 is sized to correspond to the first heat shrink sleeve 2. When replacing the NTC sensor 1, the operator can freely insert the NTC sensor 1 into the threaded shell 11. Then, the operator can place the second heat shrink sleeve 31 at a predetermined position between the NTC sensor 1 and the sealing port 3, and heat the second heat shrink sleeve 31 until it shrinks tightly onto the side wall of the NTC sensor 1 and the sealing port 3. Through the above structure, the sealing port 3 is fixed inside the threaded shell 11, and the second heat shrink sleeve 31 is provided between the sealing port 3 and the NTC sensor 1, thus fixing the wires of the NTC sensor 1. This helps to prevent the two wires of the NTC sensor 1 from contacting each other, which helps to improve the stability and practicality of the sensor device.

[0028] like Figure 2 and Figure 5As shown, a limiting hole 4 is provided on the side wall of the fixed rod 13, and multiple limiting holes 4 are arranged in a linear array; a limiting hole 4 is provided on the side wall of the limiting ring 16; a limiting pin 41 is slidably connected to the side wall of the limiting ring 16, and the limiting pin 41 is positioned corresponding to the limiting hole 4; during operation, the limiting holes 4 are provided on the side walls of the fixed rod 13 and the limiting ring 16 respectively, and the operator can fix the limiting ring 16 at a predetermined position on the side wall of the fixed rod 13 by simultaneously inserting the limiting pin 41 into the fixed rod 13 and the limiting ring 16. At this time, the distance between the limiting ring 16 and the fixed plate 14 will be determined; through the above structure, the limiting holes 4 and the limiting pin 41 are provided, and the position of the limiting ring 16 is adjustable, so that the operator can control the distance between the limiting ring 16 and the fixed plate 14, which is conducive to the operator quickly moving the NTC sensor 1 to the predetermined position and improving the convenience of the device.

[0029] like Figure 1 and Figure 5 As shown, a first magnetic ring 5 is fixedly connected to the side wall of the limiting ring 16; a second magnetic ring 51 is fixedly connected to the side wall of the fixed disk 14, and the second magnetic ring 51 is positioned corresponding to the first magnetic ring 5. During operation, whenever the limiting ring 16 moves to the position of the fixed disk 14, the first magnetic ring 5 fixed to the side wall of the limiting ring 16 will attract each other to the second magnetic ring 51 fixed to the side wall of the fixed disk 14. Through the above structure, the first magnetic ring 5 and the second magnetic ring 51 attract the fixed disk 14 to the side wall of the fixed disk 14, thereby stabilizing the position of the fixed disk 14, which helps to prevent the NTC sensor 1 from shifting during operation and improves the stability of the device.

[0030] like Figure 4 As shown, clamping protrusions 6 are fixedly attached to the side wall of clamping block 22, and multiple clamping protrusions 6 are arranged in a corresponding manner; the clamping protrusions 6 are made of high-temperature resistant plastic material; during operation, the clamping protrusions 6 made of high-temperature resistant plastic material can take advantage of the high friction and flexible texture of plastic material to replace clamping block 22 in contact with the side wall of the first heat shrink sleeve 2; through the above structure, the clamping protrusions 6 are set, and the high-temperature resistant plastic material of the clamping protrusions 6 increases the friction force on the first heat shrink sleeve 2, which is beneficial to improving the stability of NTC sensor 1, and at the same time, it is beneficial to avoid damage to NTC sensor 1 under the squeezing of clamping block 22.

[0031] like Figures 1 to 5As shown, the threaded shell 11, threaded cylinder 12, fixing rod 13, and fixing plate 14 are made of stainless steel. During operation, the use of stainless steel in the threaded shell 11, threaded cylinder 12, fixing rod 13, and fixing plate 14 allows them to take advantage of the high structural strength and durability of stainless steel. Based on the above, using stainless steel for the threaded shell 11, threaded cylinder 12, fixing rod 13, and fixing plate 14 enhances their structural strength and helps extend the service life of the device.

[0032] During operation, the operator can install the fixed plate 14 in a predetermined position using the fixing screw hole 15. Two limiting rings 16 are respectively set on the side wall of the fixing rod 13, and an operating handle 17 is fixedly connected between them. The operator can push the fixing rod 13 through the operating handle 17 to adjust the relative position of the threaded cylinder 12 and the fixed plate 14. Simultaneously, the threaded shell 11 moves synchronously, and with the movement of the threaded shell 11, the end of the NTC sensor 1 also moves. Finally, the operator can adjust the end of the NTC sensor 1 to a predetermined position whenever needed. When fixing the end of the NTC sensor 1 to the threaded housing 11, the operator can first insert the NTC sensor 1 with the first heat-shrink tubing 2 installed into the threaded housing 11. Then, the operator can rotate the two clamping blocks 22 respectively until the two clamping blocks 22 simultaneously contact the side wall of the first heat-shrink tubing 2. Finally, the operator can put the limiting sleeve 24 on the side wall of the threaded housing 11 to fix the position of the clamping blocks 22. The rotating groove 21 is set to correspond to the range of motion of the clamping blocks 22, and the clamping blocks 22 can rotate 90 degrees. The operator can adjust the clamping block 22 with the help of the auxiliary groove 23. At the position of the holding block 22, the operator can freely insert the NTC sensor 1 into the threaded housing 11. Subsequently, the operator can place the second heat shrink sleeve 31 at a predetermined position between the NTC sensor 1 and the sealing port 3, and heat the second heat shrink sleeve 31 until it shrinks tightly against the side wall of the NTC sensor 1 and the sealing port 3. Limiting holes 4 are respectively provided on the side walls of the fixing rod 13 and the limiting ring 16. The operator can fix the limiting ring 16 at a predetermined position on the side wall of the fixing rod 13 by simultaneously inserting the limiting pin 41 into the fixing rod 13 and the limiting ring 16. At this time, the distance between the limiting ring 16 and the fixed plate 14 will be determined. Whenever the limiting ring 16 moves to the position of the fixed plate 14, the first magnetic ring 5 fixed on the side wall of the limiting ring 16 will attract each other with the second magnetic ring 51 fixed on the side wall of the fixed plate 14. The clamping protrusion 6 made of high temperature resistant plastic material can take advantage of the high friction and flexible texture of plastic material to replace the clamping block 22 in contact with the side wall of the first heat shrink sleeve 2. The threaded shell 11, threaded cylinder 12, fixing rod 13 and fixed plate 14 made of stainless steel can take advantage of the high structural strength and durability of stainless steel material.
