Description

Technical Field

[0001] This utility model relates to the field of temperature sensor technology, and in particular to an immersion temperature sensor. Background Technology

[0002] A temperature sensor is a device that can sense temperature and convert it into a usable output signal. It is the core component of temperature measuring instruments. There are many types, which can be divided into two main categories according to the measurement method: contact and non-contact. According to the characteristics of sensor materials and electronic components, they can be divided into two categories: resistance temperature detectors (RTDs) and thermocouples. An immersion temperature sensor is a sensor specifically designed to measure the internal temperature of liquids, gases, or solids. Its core component is the sensing element, which usually includes thermocouples, thermistors, and RTDs. These elements will change their resistance, thermoelectric potential, or current when the temperature changes, thereby sensing the temperature.

[0003] To this end, the specification of patent number CN207502073U discloses a temperature sensor for new energy vehicles, including a flexible printed circuit board and a connector. The temperature sensor is a flexible printed circuit board temperature sensor. The temperature sensor includes a voltage acquisition unit, which is electrically and mechanically connected to the flexible printed circuit board. The flexible printed circuit board includes a fuse circuit structure to prevent the circuit from causing safety problems under overload voltage, thereby improving the safety performance of the temperature sensor.

[0004] The aforementioned temperature sensor for new energy vehicles proposes a flexible printed circuit board including a fused circuit structure to prevent safety issues caused by overload voltage, thereby improving the safety performance of the temperature sensor. However, during use, the temperature sensor body may be damaged. If the temperature sensor body is damaged, it needs to be replaced; otherwise, the entire temperature sensor needs to be replaced. Utility Model Content

[0005] The purpose of this invention is to provide an immersion temperature sensor to solve the problem that existing immersion temperature sensors are difficult to replace.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an immersion temperature sensor, including a base plate;

[0007] The top of the base plate is fitted with a housing, one end of which is fitted with a display screen and the other end of which is fitted with a knob;

[0008] A mounting plate is installed at the bottom end of the base plate, a mounting block is installed at the bottom end of the mounting plate, and a telescopic structure is installed at the bottom end of the mounting block.

[0009] A temperature sensor body is installed at the bottom of the telescopic structure, and a disassembly and assembly structure is installed at the top of the temperature sensor body. The disassembly and assembly structure includes a mounting groove installed at the bottom of the telescopic structure.

[0010] In use, the temperature sensor body can first sense the temperature, which can be displayed on the screen. The device can be controlled by a knob. The rotating shaft inside the baffle can drive the first and second protective plates to rotate through the connecting rod. The first and second protective plates can cover the surface of the display screen to protect it and prevent damage. At the same time, the protective plates are made of transparent plastic material, so the display screen can be seen through the protective plates.

[0011] Furthermore, an indicator light is installed at one end of the housing, and the indicator lights are arranged at equal intervals at one end of the housing, so that the indicator lights can indicate the operation of the device.

[0012] Furthermore, a protective structure is installed at one end of the housing, and the protective structure includes a baffle installed at one end of the housing, a rotating shaft installed on the inner side of the baffle, a connecting rod installed on one side of the rotating shaft, a first protective plate installed on one side of the connecting rod, and a second protective plate installed on one side of the connecting rod. The protective plates can protect the display screen.

[0013] Furthermore, a slot is provided on one side of the second protective plate, and a block is provided on one side of the first protective plate. The second protective plate and the first protective plate form an interlocking structure, and the first and second protective plates can cover the surface of the display screen.

[0014] Furthermore, the telescopic structure includes a first telescopic rod installed at the bottom end of the mounting block, a second telescopic rod installed at the bottom end of the first telescopic rod, a fixing screw installed on one side of the first telescopic rod, and the first and second telescopic rods can slide to adjust the height of the temperature sensor body.

[0015] Furthermore, the first telescopic rod has a sliding groove inside, and the top of the second telescopic rod has a slider. The first telescopic rod and the second telescopic rod form a sliding structure, and the second telescopic rod can slide inside the first telescopic rod.

[0016] Furthermore, the outer side wall of the fixing screw is uniformly provided with external threads, and the inner side wall of the first telescopic rod is uniformly provided with internal threads that cooperate with the external threads. The fixing screw and the first telescopic rod are threadedly connected, and the second telescopic rod can be fixed by tightening the fixing screw.

[0017] Furthermore, a connecting plate is installed inside the mounting slot, and springs are installed on both sides of the connecting plate. A buckle is installed on one side of the spring, and a pressure rod is installed on the top of the buckle. The buckle can fix the temperature sensor body.

[0018] Furthermore, the spring is helical in shape, and the spring and the buckle form an elastic connection, giving the spring elasticity.

[0019] The immersion temperature sensor provided by this utility model has the following advantages: during use, the temperature sensor body can be fixed by a snap-fit, and the temperature sensor body and the second telescopic rod form a locking structure, which allows the temperature sensor body to be replaced. At the same time, the extension and retraction of the first and second telescopic rods can adjust the height of the temperature sensor body.

[0020] A temperature sensor body is installed at the bottom of the second telescopic rod. The temperature sensor body and the second telescopic rod form a locking structure. The temperature sensor body can be locked into the second telescopic rod, and the buckle can move inside the mounting groove. The connecting plate and the buckle are connected by a spring. The spring is elastic, and the elasticity of the spring will drive the buckle to move. The buckle can lock into the inside of the locking block at the top of the temperature sensor body to fix the temperature sensor body. When the temperature sensor body needs to be replaced, pressing the pressure rod will release the buckle from locking the temperature sensor body, thus allowing the temperature sensor body to be replaced. This achieves the purpose of facilitating the replacement of the immersion temperature sensor.

[0021] A second telescopic rod is installed at the bottom of the first telescopic rod, forming a sliding structure. The second telescopic rod can slide inside the first telescopic rod, and the sliding of the second telescopic rod can adjust the height of the temperature sensor body, allowing the temperature sensor body to adapt to different situations. When the second telescopic rod needs to be replaced, the fixing screw can be tightened to fix the second telescopic rod, thereby achieving the purpose of facilitating the adjustment of the height of the immersion temperature sensor body.
