[0001] This utility model relates to the field of measurement and control device technology, specifically a measurement and control device with temperature compensation function. Background Technology

[0002] Measurement and control instruments are one of the important devices for testing the performance of electronic equipment. They can collect, process, analyze and display the characteristics of electronic equipment (such as voltage, current, frequency, signal type, etc.) to understand the performance of electronic equipment and achieve quality control of electronic equipment.

[0003] Currently, to ensure the safety of monitoring and control instruments, some instruments are equipped with external protective covers. These covers are then fixed to their installation locations (such as walls or brackets) using fasteners. However, the current method of connecting these covered instruments to the covers using fasteners (screws, bolts, etc.) makes subsequent maintenance and repair difficult and cumbersome. Therefore, a temperature-compensated monitoring and control device is proposed that facilitates easy disassembly and maintenance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a measurement and control device with temperature compensation function, which solves the problem that the measurement and control instrument is inconvenient to disassemble, inspect, and maintain inside the protective cover.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a measurement and control device with temperature compensation function, comprising:

[0006] The measuring and control instrument has an elastic buckle fixedly installed on its side wall.

[0007] The mounting cover is movably fitted onto the outside of the measuring and control instrument. The inner side wall of the mounting cover has a straight groove for the movement of the elastic buckle, and the inner wall of the straight groove has a buckle groove that matches the elastic buckle.

[0008] A plug-in frame is fixedly connected to the side wall of the measuring and control instrument. The plug-in frame has a plug cavity with openings at the top and front. The plug-in frame is movably connected to a plug plate through the plug cavity. One end of the elastic buckle is bent and passes through the opening of the side wall of the plug cavity and is fixedly connected to the side wall of the plug plate.

[0009] Preferably, the elastic buckle is made of an elastic material, and the end of the elastic buckle facing away from the insert plate is trapezoidal.

[0010] Preferably, a replacement frame is fixedly provided in the buckle groove, and the middle of the replacement frame is provided with a rectangular through hole that can be movably engaged with the elastic buckle.

[0011] Preferably, the replacement frame has a stepped groove on the side near the outer wall of the mounting cover, and the shape of the snap-fit ​​groove is adapted to the shape of the stepped groove. The replacement frame has a limiting structure on the side facing the outer wall of the mounting cover, and the limiting structure is used to prevent the replacement frame from detaching from the snap-fit ​​groove.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This application provides a measurement and control device with temperature compensation function, which solves the problem that the measurement and control instrument 100 is inconvenient to disassemble, inspect, and maintain inside the mounting cover 200. By using the cooperation of the linear slot 201, the snap-fit ​​slot 202, and the elastic snap 205, the disassembly and assembly of the measurement and control instrument 100 inside the mounting cover 200 is made more convenient and efficient, thereby facilitating the rapid disassembly, assembly, inspection, and maintenance of the measurement and control instrument 100 inside the mounting cover 200.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] This utility model discloses a measurement and control device with temperature compensation function.

[0029] According to the appendix Figure 1As shown in Figure 5, the device includes a control unit 100 and a mounting cover 200. To enable the control unit to have a temperature compensation function, the control unit 100 needs to use a control instrument with an integrated temperature sensor, as is available in the prior art. By integrating the temperature sensor (thermocouple, thermistor, or digital temperature sensor) into the control unit 100, the ambient temperature or the operating temperature of the control unit 100 is monitored in real time. The output signal of the temperature sensor is connected to the control system within the control unit 100 to acquire temperature data in real time. The control system can dynamically adjust the measurement results based on the real-time temperature data. For example, in voltage or current measurements, compensation calculations are performed using known temperature and output relationships to correct the measured values. A flexible buckle 205 is fixedly installed on the side wall of the measuring and control instrument 100. A mounting cover 200 is movably fitted onto the outside of the measuring and control instrument 100. The inner side wall of the mounting cover 200 has a linear slot 201 for the movement of the flexible buckle 205. The inner wall of the linear slot 201 has a buckle groove 202 that matches the flexible buckle 205. Fasteners can be configured on the mounting cover 200 to facilitate its installation and fixation in an external position. When the controller 100 is inserted from the front port of the mounting cover 200, the linear slot 201 on the inner wall of the mounting cover 200 allows the elastic buckle 205 protruding from the side wall of the controller 100 to smoothly enter the mounting cover 200. The inner wall of the linear slot 201 presses against the end of the elastic buckle 205, causing the elastic buckle 205 to move inward with the controller 100 to the buckle groove 202. At this position, the end of the elastic buckle 205 automatically engages in the buckle groove 202 using its elastic deformation capability, thereby achieving… The horizontal limit between the measuring and control instrument 100 and the mounting cover 200 ensures that the measuring and control instrument 100 can be securely installed inside the mounting cover 200 for protection. Conversely, during disassembly, the user only needs to manually press the end of the elastic buckle 205 protruding from the buckle groove 202 on the side wall of the mounting cover 200. By pressing, the end of the elastic buckle 205 is disengaged from the buckle groove 202, thereby releasing the horizontal limit of the measuring and control instrument 100. This allows the measuring and control instrument 100 to be directly pulled out for disassembly, achieving one-click disassembly. The operation is simple and convenient.

[0030] Additionally, the connector frame 203 is fixedly connected to the side wall of the measuring and control instrument 100. The connector frame 203 has a cavity with openings at the top and front. The connector frame 203 is movably connected to the insert plate 204 through the cavity. One bent end of the elastic buckle 205 passes through the opening in the side wall of the cavity and is fixedly connected to the side wall of the insert plate 204. The elastic buckle 205 is made of elastic material, and the end of the elastic buckle 205 facing away from the insert plate 204 is trapezoidal. By inserting the insert plate 204 vertically downward from the top of the connector frame 203, the elastic buckle 205 can be installed on the side wall of the measuring and control instrument 100. At the same time, after the measuring and control instrument 100 is inserted into the inside of the mounting cover 200, the mounting cover 200 can... The vertical position of the measuring and control instrument 100 is blocked and limited, preventing the elastic buckle 205 from moving vertically from the side wall of the measuring and control instrument 100 through the insert plate 204. This ensures the stable installation of the elastic buckle 205 on the side wall of the measuring and control instrument 100 and does not affect the locking of the measuring and control instrument 100 inside the mounting cover 200. When the elastic buckle 205 suffers elastic fatigue or damage, the user can simply pull out the insert plate 204 from the insertion frame 203 to remove the elastic buckle 205 and then replace it with the elastic buckle 205 with the insert plate 204. This makes the replacement of the elastic buckle 205 on the side wall of the measuring and control instrument 100 more convenient.

[0031] Furthermore, a replacement frame 206 is fixedly provided inside the snap-fit ​​groove 202. The replacement frame 206 has a rectangular through hole in the middle for movably engaging with the elastic snap 205. A stepped groove 207 is provided on the side of the replacement frame 206 near the outer wall of the mounting cover 200. The shape of the snap-fit ​​groove 202 matches the shape of the stepped groove 207. A limiting structure is provided on the side of the replacement frame 206 facing the outer wall of the mounting cover 200. The limiting structure is used to prevent the replacement frame 206 from detaching from the snap-fit ​​groove 202. By adding a replacement frame 206 to the snap-fit ​​groove 202, the snap-fit ​​groove 202 position on the mounting cover 200 can be protected to avoid wear caused by repeated contact and friction with the elastic snap 205, thereby extending the service life of the mounting cover 200. Moreover, the replacement frame 206 is detachably connected to the snap-fit ​​groove 202 position through the limiting component, so that the replacement frame 206 can be disassembled and replaced on the mounting cover 200, thereby meeting the replacement needs of the replacement frame 206.

[0032] The limiting structure includes a blocking component. The side wall of the replacement frame 206 passes through the snap-fit ​​groove 202 and extends to a position flush with the outer wall of the mounting cover 200. The blocking component is rotatably connected to the side of the replacement frame 206 facing the outer wall of the mounting cover 200. The blocking component includes a blocking block 208 and a connecting pin 209. The blocking block 208 is an irregular circle with a protrusion on its circumferential wall. The connecting pin 209 is rotatably connected to the middle of the blocking block 208, and one end of the connecting pin 209 is fixedly connected to the outer wall of the replacement frame 206. Because the replacement frame 206 is provided with a stepped groove 207 forming a shape that is wider on one side and narrower on the other, and the snap-fit ​​groove 202 is adapted to the shape of the replacement frame 206 with the stepped groove 207, it is possible to... The snap-fit ​​groove 202 blocks and limits the outward movement of the replacement frame 206. Then, in conjunction with the interference fit between the blocking block 208 and the connecting pin 209, the blocking block 208 can rotate until its outer circumferential protrusion moves to the outer wall of the mounting cover 200. This limits the inward movement of the replacement frame 206 towards the mounting cover 200, allowing the replacement frame 206 to be securely installed in the snap-fit ​​groove 202. When disassembling and replacing, simply move the blocking block 208 so that its outer circumferential protrusion moves away from the side wall of the mounting cover 200, allowing the replacement frame 206 to move from the inner wall of the mounting cover 200. This makes the disassembly and replacement of the replacement frame 206 in the snap-fit ​​groove 202 more convenient and efficient.
