Description

Technical Field

[0001] This utility model belongs to the field of temperature sensor technology and relates to a temperature sensor. Background Technology

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. Temperature sensors are the core component of temperature measuring instruments. There are many types of temperature sensors, which can be divided into two main categories according to the measurement method: contact type and non-contact type. According to the characteristics of sensor materials and electronic components, they can be divided into two categories: resistance temperature detectors (RTDs) and thermocouples.

[0003] Because temperature sensors are used for temperature measurement, they are often exposed to harsh environments, frequently leading to problems such as damage to internal electronic components or short circuits. Therefore, when a temperature sensor malfunctions, personnel need to open the sensor housing to inspect and replace internal parts. Disassembling and repairing existing temperature sensors is very cumbersome, and reassembling them after repair is also inconvenient. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a temperature sensor that is easy to install and maintain.

[0005] The objective of this utility model can be achieved through the following technical solution: A temperature sensor includes a sensor body, on which a sensor housing is provided. The sensor housing is characterized by a detachable sealing cover, four fixing parts on the periphery of the sensor housing, and a positioning component for fixing the sealing cover on each fixing part. The sealing cover has an integrally formed mounting part that abuts against the upper surface of the sensor housing. The four fixing parts have slots, and the mounting part, corresponding to the slots of the fixing parts, has a snap-fit ​​part that cooperates with the positioning component. The positioning component consists of a positioning rod, a lifting part, a sliding part, and a return spring. The fixing parts have mounting slots for installing the positioning component, and the snap-fit ​​part has a positioning hole that cooperates with the positioning rod. The sealing cover is detachably and fixedly installed on the sensor body by the cooperation of the positioning rod and the positioning hole.

[0006] In the aforementioned temperature sensor, one end of the positioning rod extends out of the mounting groove and abuts against the positioning hole of the snap-fit ​​part, while the other end of the positioning rod extends out of the mounting groove and is connected to the lifting part. The reset spring is disposed in the mounting groove, with one end connected to the sliding part and the other end connected to the fixing part.

[0007] In the aforementioned temperature sensor, the sealing cover is provided with a sealing part, and the sealing part and the sealing cover are integrally formed. When the sealing cover is installed, the outer peripheral wall of the sealing part abuts against the inner peripheral wall of the sensor body.

[0008] In the aforementioned temperature sensor, the fixing part is provided in two sections, one at the front and one on the left and one on the right, and each fixing part has a positioning component.

[0009] Compared with existing technologies, the sealing cover in this temperature sensor can be detachably and fixedly installed on the sensor body, which facilitates the maintenance and replacement of internal parts of the temperature sensor by the staff. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model.

[0011] Figure 2 This is a cross-sectional structural diagram of the present invention.

[0012] In the figure, 1 is the sensor body; 2 is the sensor housing; 3 is the sealing cover; 4 is the fixing part; 5 is the snap-fit ​​part; 6 is the positioning rod; 7 is the lifting part; 8 is the sliding part; 9 is the return spring; and 10 is the sealing part. Detailed Implementation

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1 , Figure 2 As shown, this temperature sensor includes a sensor body 1, on which a sensor housing 2 is provided. The sensor housing 2 is characterized by a detachable sealing cover 3. Four fixing parts 4 are provided around the periphery of the sensor housing 2. Each fixing part 4 has a positioning component for fixing the sealing cover 3. The sealing cover 3 has an integrally formed mounting part that abuts against the upper surface of the sensor housing 2. The four fixing parts 4 have slots. Each mounting part, corresponding to the slot of the fixing part 4, has a snap-fit ​​part 5 that cooperates with the positioning component. The positioning component consists of a positioning rod 6, a lifting part 7, a sliding part 8, and a return spring 9. Each fixing part 4 has an installation slot for installing the positioning component. The snap-fit ​​part 5 has a positioning hole that cooperates with the positioning rod 6. The sealing cover 3 is detachably and fixedly installed on the sensor body 1 by the cooperation of the positioning rod 6 and the positioning hole.

[0015] To elaborate further, one end of the positioning rod 6 extends out of the mounting groove and abuts against the positioning hole of the snap-fit ​​part 5, while the other end of the positioning rod 6 extends out of the mounting groove and is connected to the lifting part 7. The reset spring 9 is disposed in the mounting groove, with one end of the reset spring 9 connected to the sliding part 8 and the other end connected to the fixing part 4.

[0016] To elaborate further, when the sealing cover 3 needs to be disassembled, the lifting part 7 is pulled to retract the positioning rod 6 into the mounting groove, releasing the positioning of the positioning rod 6 and the positioning hole on the locking part 5 of the sealing cover 3, thus removing the sealing cover 3 from the sensor body 1. When the sealing cover 3 needs to be installed, the lifting part 7 is pulled to retract the positioning rod 6 into the mounting groove, compressing the return spring 9. Then, the locking part 5 on the sealing cover 3 is aligned with the slot of the fixing part 4. After the locking part 5 is installed, the return spring 9 rebounds, and the positioning rod 6 extends out of the mounting groove and into the positioning hole, thereby fixing the sealing cover 3 to the sensor body 1.

[0017] To elaborate further, the sealing cover 3 is provided with a sealing part 10, and the sealing part 10 is integrally formed with the sealing cover 3. When the sealing cover 3 is installed, the outer peripheral wall of the sealing part 10 abuts against the inner peripheral wall of the sensor body 1. The sealing part 10 enhances the sealing performance of the sensor body 1 and improves the service life of the sensor body 1.

[0018] To elaborate further, the fixing part 4 is provided in two parts at the front and back and two parts on the left and right, and each fixing part 4 has a positioning component.

[0019] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0020] Although this document frequently uses terms such as sensor body 1, sensor housing 2, sealing cover 3, fixing part 4, snap-fit ​​part 5, positioning rod 6, lifting part 7, sliding part 8, return spring 9, and sealing part 10, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
