Description

Technical Field

[0001] This utility model relates to the field of sensor technology, specifically to sensor devices. Background Technology

[0002] A temperature sensor is a device that can sense temperature changes and convert them into a usable output signal. It is a core component of temperature measuring instruments. According to the different temperature measurement methods, temperature sensors can be divided into two main categories: contact and non-contact. According to the materials and electronic components used in the sensor, they can be mainly divided into two categories: resistance temperature detectors (RTDs) and thermocouples. They are diverse in type and widely used, playing a key role in various temperature monitoring and control systems.

[0003] However, during long-term storage, the sensing needles of existing temperature sensors are usually directly exposed to the external environment, making them susceptible to corrosion from environmental factors such as dust and moisture. At the same time, the sensing needles are also easily damaged by bumps during storage and handling, which affects the sensing accuracy and measurement reliability during use and shortens the lifespan of the sensor. In addition, the wires equipped with existing sensors are generally long, which are prone to tangling and mess during storage, not only taking up space but also making management inconvenient. Utility Model Content

[0004] The present invention aims to address the shortcomings of the prior art by providing a sensor device. To solve the above problems, the sensor needle can be effectively protected by the protective component to prevent corrosion from external factors and damage caused by physical collisions. The temperature sensor wire can be wound up by the storage component, and excess wire can be stored during use to avoid the working environment becoming cluttered due to excessive wire length.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sensor device, comprising: a housing, a temperature sensor body disposed inside the housing, a sensing needle fixedly connected to the bottom of the temperature sensor body, a cover disposed on the top of the housing, and a protective component disposed at the bottom of the housing, the protective component comprising: a protective sleeve, a spring sheet, a pull rod, a pull plate, and a sealing ring.

[0008] Furthermore, the top of the protective sleeve has a through hole, and a sealing ring is fixedly installed inside the through hole. The bottom end of the outer shell passes through the through hole and extends into the cavity a.

[0009] Furthermore, a storage assembly is provided between the outer shell and the cover. The storage assembly includes: a rubber winding drum disposed on the outside of the outer shell, a perforation at the top of the rubber winding drum, a winding groove at the outside of the rubber winding drum, a plurality of limiting grooves at the top of the rubber winding drum, a wire wound inside the winding groove, one end of the wire being connected to the temperature sensor body, an annular threaded block fixedly installed on the outside of the rubber winding drum, the annular threaded block having an external thread on its outside, and a cavity b at the bottom of the cover.

[0022] This application provides a sensor device that effectively protects the sensing needle from external corrosion and physical impact through a protective component. Furthermore, a storage component allows for the winding of the temperature sensor wire, preventing excess wire from becoming too long and cluttering the working environment. The sensor device will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0023] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] Please see Figure 1-5 In this embodiment, a sensor device is provided, including: a housing 1, a temperature sensor body 101 is provided inside the housing 1, a sensing needle 103 is fixedly connected to the bottom of the temperature sensor body 101, and a cover 4 is provided on the top of the housing 1; a protective component is provided at the bottom of the housing 1, the protective component includes: a protective sleeve 3, a spring sheet 304, a pull rod 305, a pull plate 307 and a sealing ring 303.

[0025] The outer shell 1 has a protective sleeve 3 at its bottom, a cavity a308 at its top, a slot 104 on one side of the outer shell 1, and a positioning hole 306 on one side of the protective sleeve 3. A spring groove 301 is formed inside the protective sleeve 3, and a spring sheet 304 is fixedly connected inside the spring groove 301. A pull rod 305 is fixedly connected to one side of the spring sheet 304. One end of the pull rod 305 passes through the positioning hole 306 and is fixedly connected to a pull plate 307. One side of the spring sheet 304 engages with the slot 104. A through hole 302 is formed at the top of the protective sleeve 3, and a sealing ring 303 is fixedly installed inside the through hole 302. The bottom end of the outer shell 1 passes through the through hole 302 and extends into the cavity a308.

[0026] Because the sensing needle 103 of the existing temperature sensor is exposed during storage, it is easily damaged by bumps and knocks, affecting the accuracy of subsequent detection. Therefore, a protective component can be used to protect it. During installation, the pull plate 307, spring plate 304, and slot 104 can be vertically aligned. Then, the bottom end of the sensing needle 103 is inserted into the cavity a308 until the bottom of the outer shell 1 slides into the cavity a308. At this time, the outer shell 1 will compress the spring plate 304, causing it to elastically deform until the slot 104 on one side of the outer shell 1 corresponds to the spring groove 301, at which point the spring plate 304 is released. Insert the protective sleeve 3 into the slot 104 to fix it onto the outer shell 1. Since the sealing ring 303 is made of rubber, when the outer shell 1 is inserted into the cavity a308, it will compress the sealing ring 303 to a certain extent. This not only makes the connection between the outer shell 1 and the protective sleeve 3 more stable, but also prevents dust from entering the cavity a308 and reduces the adhesion of dust or moisture on the surface of the sensing needle 103. When it is necessary to remove the protective sleeve 3, pull the pull plate 307 to move the pull rod 305 to move one side of the spring plate 304 away from the outer shell 1, thereby removing the spring plate 304 from the slot 104. Then, pull the outer shell 1 upward to remove the protective sleeve 3.

[0027] The housing 1 and the cover 4 are provided with a storage assembly, which includes: a rubber winding drum 2 located on the outside of the housing 1, a through hole 204 on the top of the rubber winding drum 2, a winding groove 202 on the outside of the rubber winding drum 2, and multiple limiting grooves 203 on the top of the rubber winding drum 2. A wire 102 is wound inside the winding groove 202, and one end of the wire 102 is connected to the temperature sensor body 101. An annular threaded block 201 is fixedly installed on the outside of the rubber winding drum 2, and the annular threaded block 201 has an external thread on its outside; a cavity b401 located at the bottom of the cover 4; an internal thread is provided inside the through hole 204, and an external thread is provided on the outside of the housing 1. The housing 1 is threadedly connected to the through hole 204; an internal thread is provided inside the cavity b401 that matches the external thread on the outside of the annular threaded block 201, and the cover 4 is threadedly connected to the annular threaded block 201.

[0028] Since the wire 102 of the temperature sensor body 101 is relatively long, it is usually wound up for storage. However, it is easy to loosen after winding. Therefore, it can be improved by using a storage component. When in use, one end of the wire 102 can be inserted into the limiting groove 203, and then the wire 102 can be wound around the winding groove 202. When it is wound to a certain extent, it is tightened, and one end of the wire 102 is inserted into another limiting groove 203. Since the rubber winding drum 2 is made of rubber material and has a certain elasticity, it can hold the wire 102 after it is inserted into the limiting groove 203. Then, the top of the outer shell 1 is screwed into the bottom cavity b401 of the cover 4 to complete the storage of the wire 102.

[0029] In addition, when the wire 102 is needed, the cover 4 can be rotated to remove the cover 4 from the rubber take-up drum 2, and then one end of the wire 102 can be pulled out from the limiting groove 203. A certain length of the wire 102 can be released according to the actual length requirement of the wire 102. Then the wire 102 can be put back into the limiting groove 203 to limit the wire 102 again, preventing the wire 102 from being released too much and causing the working environment to become messy.

[0030] The working principle is as follows:

[0031] Because the sensing needle 103 of the existing temperature sensor is exposed during storage, it is easily damaged by bumps and knocks, affecting the accuracy of subsequent detection. Therefore, a protective component can be used to protect it. During installation, the pull plate 307, spring plate 304, and slot 104 can be vertically aligned. Then, the bottom end of the sensing needle 103 is inserted into the cavity a308 until the bottom of the outer shell 1 slides into the cavity a308. At this time, the outer shell 1 will compress the spring plate 304, causing it to elastically deform until the slot 104 on one side of the outer shell 1 corresponds to the spring groove 301, at which point the spring plate 304 is released. Insert the protective sleeve 3 into the slot 104 to fix it onto the outer shell 1. Since the sealing ring 303 is made of rubber, when the outer shell 1 is inserted into the cavity a308, it will compress the sealing ring 303 to a certain extent. This not only makes the connection between the outer shell 1 and the protective sleeve 3 more stable, but also prevents dust from entering the cavity a308 and reduces the adhesion of dust or moisture on the surface of the sensing needle 103. When it is necessary to remove the protective sleeve 3, pull the pull plate 307 to move the pull rod 305 to move one side of the spring plate 304 away from the outer shell 1, thereby removing the spring plate 304 from the slot 104. Then, pull the outer shell 1 upward to remove the protective sleeve 3.

[0032] Furthermore, since the wire 102 of the temperature sensor body 101 is relatively long, it is usually wound up for storage. However, it is easy to loosen after winding. Therefore, this can be improved by using a storage component. When in use, one end of the wire 102 can be inserted into the limiting groove 203, and then the wire 102 can be wound around the winding groove 202. When it is wound to a certain extent, it is tightened, and one end of the wire 102 is inserted into another limiting groove 203. Since the rubber winding drum 2 is made of rubber material and has a certain elasticity, it can hold the wire 102 after it is inserted into the limiting groove 203. Then, the top of the outer shell 1 is screwed into the bottom cavity b401 of the cover 4 to complete the storage of the wire 102.

[0033] In addition, when the wire 102 is needed, the cover 4 can be rotated to remove the cover 4 from the rubber take-up drum 2, and then one end of the wire 102 can be pulled out from the limiting groove 203. A certain length of the wire 102 can be released according to the actual length requirement of the wire 102. Then the wire 102 can be put back into the limiting groove 203 to limit the wire 102 again, preventing the wire 102 from being released too much and causing the working environment to become messy.
