[0003] However, existing RTD wafer temperature sensors with integrated Bluetooth transmission still have shortcomings in practical use. The installation and fixing structure of some sensors is complex, and the disassembly and replacement process is cumbersome, consuming a lot of time and manpower. At the same time, the sensor body lacks an effective protective structure, and it is easily damaged by collisions and friction during installation or use, affecting the detection accuracy and service life. Utility Model Content

[0004] The purpose of this invention is to provide an RTD Wafer temperature sensor with integrated Bluetooth transmission, which solves the problems of complex installation and fixing structures, cumbersome disassembly and replacement processes, and high time and manpower consumption of some sensors in the prior art; at the same time, the sensor body lacks an effective protective structure, and is easily damaged by collision and friction during installation or use, affecting the detection accuracy and service life.

[0005] To achieve the above objectives, this utility model provides an RTD Wafer temperature sensor with integrated Bluetooth transmission, including a mounting box. The mounting box contains a convenient fixing component. An auxiliary component is provided on one side of the convenient fixing component. The convenient fixing component includes a sensor body. Two protective semi-rings are symmetrically arranged on the outer wall of the sensor body. A lower protrusion is fixedly connected to the bottom of each of the two protective semi-rings. A sleeve is fixedly connected to one side of the lower protrusion. An outer ring is slidably connected to the inner wall of the sleeve. A pin is fixedly connected inside the outer ring. A spring is also fixedly connected to one side of the lower protrusion, with one end of the spring fixedly connected to one side of the outer ring. An auxiliary support block is fixedly connected to the bottom inner wall of the mounting box, and the interior of the auxiliary support block is fixedly connected to the outer wall of the sleeve.

[0006] The mounting box has two support rods fixedly connected to its inner bottom. The support rods are arranged symmetrically to each other, and the tops of the two support rods are fixedly connected to limit frames.

[0007] The mounting box has a rotating shaft rotatably connected to the bottom side wall, a screw fixedly connected to the top of the rotating shaft, and a nut sleeve threadedly connected to the outer wall of the screw.

[0008] The nut sleeve is rectangular, and a triangular block is fixedly connected to the top of the nut sleeve. The nut sleeve is slidably connected to the inner wall of the limiting frame, and the two inclined surfaces of the triangular block are in contact with one end of the pin.

[0009] The bottom of the rotating shaft has a hexagonal socket, and a hexagonal wrench is inserted into the hexagonal socket to drive the rotating shaft to rotate.

[0010] The auxiliary component includes a slot and a plug. The slot is located at one end of the protective half-ring, and the plug is fixedly connected to one end of the other protective half-ring. The plug is inserted into the inside of the slot.

[0011] The protective semi-ring has a countersunk groove at its top, and the auxiliary component also includes a bolt. The bolt passes through the bottom of the countersunk groove and is connected to the internal thread of the insert block. The head of the bolt is completely located inside the countersunk groove.

[0012] The outer wall of the protective semi-ring is fixedly connected to a positioning slider, which is slidably connected to the inside of the side wall of the mounting box on the corresponding side.

[0013] Beneficial effects Compared with existing technologies, it has the following advantages: 1. In this utility model, a convenient fixing component is provided. Rotating the shaft with a hex wrench drives the screw to rotate, which in turn moves the nut sleeve and the triangular block. The inclined surface of the triangular block presses against the pin, causing one end of the pin to insert into the lower protrusion for fixation. This achieves precise positioning and fixation of the sensor body by the two protective semi-rings. The installation and disassembly process is simple, saving time and manpower. The two protective semi-rings are symmetrically wrapped around the outer wall of the sensor body, forming a close-fitting protective structure. This effectively prevents the sensor body from being damaged by collisions or friction during installation or use, extending the sensor's service life and ensuring detection accuracy.

[0014] 2. In this utility model, the cooperation between the insert block and the slot in the auxiliary component, as well as the sliding connection between the positioning slider and the side wall of the mounting box, improves the positioning accuracy of the protective half-ring during installation, avoids sensor body misalignment, and ensures precise detection position. The threaded connection between the bolt and the insert block further strengthens the connection stability of the two protective half-rings. Simultaneously, the bolt head is located within the countersunk groove, preventing interference or damage caused by protruding structures and improving the overall structural compactness. The spring design allows the outer ring and pin to reset during disassembly, facilitating quick release of the protective half-ring and further enhancing operational convenience.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Reference Figures 1-10This utility model provides a technical solution: an RTDWafer temperature sensor with integrated Bluetooth transmission, including a mounting box 1. The mounting box 1 has a convenient fixing component 2 inside, and an auxiliary component 3 is provided on one side of the convenient fixing component 2. The convenient fixing component 2 includes a sensor body 21, which integrates a Bluetooth transmission module to wirelessly transmit detected temperature data to a receiving device. A protective semi-ring 22 is fitted onto the outer wall of the sensor body 21. The protective semi-rings 22 are made of wear-resistant and impact-resistant material, and there are two of them, symmetrically arranged. Their inner walls fit snugly against the outer wall of the sensor body 21, forming a wrap-around protection. The two protective semi-rings 22 maintain a fixed distance and do not shift relative to each other. A lower protrusion 23 is fixedly connected to the bottom of the two protective semi-rings 22. A sleeve 24 is fixedly connected to one side of the lower protrusion 23. An outer ring 27 is slidably connected to the inner wall of the sleeve 24. A pin 26 is fixedly connected inside the outer ring 27, and the pin 26 can slide within the sleeve 24 with the outer ring 27. A spring 28 is fixedly connected to one side of the lower protrusion 23. One end of the spring 28 is fixedly connected to one side of the outer ring 27. The spring 28 is normally in a naturally extended state. An auxiliary support block 25 is fixedly connected to the inner bottom of the mounting box 1. The interior of the auxiliary support block 25 is fixedly connected to the outer wall of the sleeve 24 for fixing and supporting the sleeve 24. A support rod 211 is fixedly connected to the inner bottom of the mounting box 1. There are two support rods 211, which are symmetrically arranged. A limit frame 212 is fixedly connected to the top of the two support rods 211. The limit frame 212 is a cuboid frame structure used to limit the movement direction of the nut sleeve 210. A rotating shaft 213 is rotatably connected inside the bottom side wall of the mounting box 1. The rotating shaft 213 can rotate freely inside the side wall of the mounting box 1. A screw 214 is fixedly connected to the top of the rotating shaft 213. A nut sleeve 210 is threadedly connected to the outer wall of the screw 214. When the screw 214 rotates, it can drive the nut sleeve 210 to move along the axial direction of the screw 214. The nut sleeve 210 is rectangular and slides along the inner wall of the limiting frame 212, ensuring that the nut sleeve 210 moves in a straight line. A triangular block 29 is fixedly connected to the top of the nut sleeve 210. The two inclined surfaces of the triangular block 29 contact one end of the pin 26. One end of the pin 26 can be inserted into the lower protrusion 23. When the triangular block 29 moves, it can press the pin 26 through the inclined surfaces to move and insert it into the lower protrusion 23. A hexagonal socket 215 is provided at the bottom of the rotating shaft 213. A hexagonal wrench inserted into the hexagonal socket 215 can drive the rotating shaft 213 to rotate, which is convenient for operators.

[0020] Reference Figures 1-4 , Figure 7 , Figures 9-10In one aspect of this embodiment, the auxiliary component 3 includes a slot 31 and a plug 32. The slot 31 is located at one end of the protective half-ring 22, and the plug 32 is fixedly connected to one end of the other protective half-ring 22. The size of the plug 32 matches the slot 31, and it can be inserted into the slot 31 to achieve a positioning connection between the ends of the two protective half-rings 22, further stabilizing their relative positions. A countersunk groove 34 is provided at the top of the protective half-ring 22. The auxiliary component 3 also includes a bolt 33, which passes through the bottom of the countersunk groove 34 and is threaded into the inside of the plug 32 to reinforce the connection between the two protective half-rings 22. The head of the bolt 33 is completely located inside the countersunk groove 34 to avoid interference caused by the head protruding. A positioning slider 35 is fixedly connected to the outer wall of the protective half-ring 22. The positioning slider 35 is slidably connected to the inner side wall of the mounting box 1 on the corresponding side, so that the protective half-ring 22 is kept in a fixed position within the mounting box 1, ensuring accurate installation positioning.

[0021] Working Principle: During installation and fixation of the integrated Bluetooth-enabled RTDWafer temperature sensor, the sensor body 21 is first placed between two symmetrically arranged protective semi-rings 22, ensuring the inner walls of the two protective semi-rings 22 are in contact with the outer wall of the sensor body 21. Then, the insert 32 on one protective semi-ring 22 is inserted into the slot 31 on the other protective semi-ring 22, achieving initial positioning of the ends of the two protective semi-rings 22. Simultaneously, the positioning slider 35 on the outer wall of the protective semi-ring 22 is embedded inside the side wall of the mounting box 1, ensuring the overall position of the protective semi-rings 22 is fixed and does not shift. Next, a hex wrench is inserted into the hexagonal socket 215 at the bottom of the rotating shaft 213. Rotating the hex wrench drives the rotating shaft 213 to rotate, which in turn drives the top screw 214 to rotate synchronously. Because the nut sleeve 210 is slidably connected to the limiting frame 212, it cannot rotate with the screw 214. Under the action of the thread, the nut sleeve 210 moves upward along the screw 214, causing the top triangular block 29 to move upward synchronously. When the triangular block 29 moves upward, its inclined surfaces press against the pins 26 on both sides, causing the pins 26 to move away from the triangular block 29. The pins 26 drive the outer ring 27 to slide within the sleeve 24, simultaneously compressing the spring 28, until one end of the pin 26 inserts into the lower protrusion 23, thus limiting and fixing the lower protrusion 23. This keeps the two protective half-rings 22 in a fixed position against the sensor body 21, completing the limiting and fixing of the sensor body 21. Subsequently, the bolt 33 is passed through the countersunk groove 34 at the top of the protective half-ring 22 and connected to the internal thread of the insert block 32. Tightening the bolt 33 further strengthens the connection stability of the two protective half-rings 22, ensuring that the sensor body 21 is always in a stable protective state. The head of the bolt 33 is completely within the countersunk groove 34, preventing protruding structures from affecting other components or causing damage. When it is necessary to disassemble or replace the sensor body 21, first unscrew the bolt 33, then turn the hex wrench in the opposite direction to drive the shaft 213 and screw 214 to rotate in the opposite direction. The nut sleeve 210 drives the triangular block 29 to move downward, and the squeezing force of the triangular block 29 on the pin 26 disappears. At this time, the spring 28 returns to its extension under its own elastic force, pushing the outer ring 27 and pin 26 to reset. The pin 26 is pulled out from the lower protrusion 23, releasing the limiting fixation of the protective half-ring 22. After that, pull the insert 32 out of the slot 31 to remove the protective half-ring 22 and take out the sensor body 21 for replacement or maintenance. When the sensor body 21 is working, it collects temperature data through its own detection element and wirelessly transmits the data to the designated receiving device through the integrated Bluetooth transmission module, realizing remote acquisition of temperature data. The two protective half-rings 22 always remain in a fixed state in contact with the sensor body 21, playing an effective protective role and avoiding damage from collisions and friction, ensuring the long-term stable operation of the sensor body 21.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
