Description

Technical Field

[0001] This utility model relates to the field of temperature sensor technology, specifically a waterproof and corrosion-resistant armored temperature sensor. Background Technology

[0002] A temperature sensor is a sensor that senses temperature and converts it into a usable output signal. Temperature sensors are the core component of temperature measuring instruments and come in many varieties. They can be broadly classified into two categories based on measurement method: contact and non-contact. Based on sensor materials and electronic component characteristics, they are classified into resistance temperature detectors (RTDs) and thermocouples. An existing patent, patent publication number CN116839748A, describes an armored thin-film temperature sensor, which includes an explosion-proof enclosure housing the thin-film temperature sensor, an explosion-proof mechanism surrounding the sensor to prevent damage in case of equipment malfunction, and a measuring mechanism mounted on one side of the enclosure for accurate temperature measurement. This invention utilizes a customizable explosion-proof enclosure to effectively protect the thin-film temperature sensor, improving the overall explosion-proof function and safety of the equipment while ensuring heat dissipation and increasing stability during use. Furthermore, the inclusion of a thin-film temperature sensor and a platinum resistance element enhances temperature measurement accuracy and response speed, increasing practicality. The device also features O-rings and explosion-proof mating surfaces for improved overall sealing.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: although they can be protected by explosion-proof boxes during use, the lack of an effective detachable connection structure makes it easy for the threaded connection to loosen due to long-term wear, resulting in poor sealing and potential leakage. Therefore, we propose a waterproof and corrosion-resistant armored temperature sensor to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a waterproof and corrosion-resistant armored temperature sensor. This solves the problem that existing threaded connections, due to the lack of an effective detachable connection structure, are prone to loosening over time due to wear, resulting in poor sealing and potential leakage.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a waterproof and corrosion-resistant armored temperature sensor, including a base, the main body of which is a frustoconical structure with a thicker upper part and a thinner lower part, and a sleeve is fixedly connected to the bottom end face of the base, and the main body of the sleeve is a bidirectional through structure on both the upper and lower sides, the diameter of the sleeve is smaller than the diameter of the base, and the base and the sleeve together form a connecting structure, and a through hole is opened on the outer circumferential surface of the sleeve, the through hole being a first mounting groove, and there are two first mounting grooves, which are opened opposite each other on the front and rear sides of the outer circumferential surface of the sleeve.

[0006] Preferably, an annular groove is provided on the top surface of the seat, which is a second mounting groove, and a connecting frame is fixedly connected to the inner side of the seat. There are four connecting frames, which are fixedly connected to the inner wall of the seat in a circular array.

[0007] Preferably, a support base is fixedly connected to the inner side of the four connecting frames, and the main body of the support base is a ring structure. The support base and the connecting frame together form an installation structure. A cover plate is installed on the top of the base. The cover plate has a circular cross-section and notches are arranged in a ring array on the outer circumference of the cover plate.

[0008] Preferably, the notch on the outer circumferential surface of the cover plate is an anti-slip groove, and a sealing ring is fixedly connected to the bottom end surface of the cover plate. The main body of the sealing ring is an annular structure, and the sealing ring is made of rubber.

[0009] Preferably, a plug is fixedly connected to the bottom end face of the cover plate, and the main body of the plug is a cylindrical structure. External threads are formed in a ring array on the outer circumferential surface of the plug, and a temperature probe, which is a contact sensor, is fixedly connected to the bottom end face of the plug.

[0010] Preferably, a connecting pipe is inserted into the bottom end of the sleeve, and the outer circumferential surface of the connecting pipe is provided with external threads. The connecting pipe is used to connect with external pipelines, and the diameter of the connecting pipe is smaller than the diameter of the sleeve.

[0011] Preferably, a guide ball is installed on the outer circumferential surface of the connecting tube, and there are two guide balls in total.

[0025] By fixing a sleeve 101 to the bottom end face of the seat 1, the seat 1 can be extended and reinforced as a whole during use.

[0026] See Figure 1 , Figure 2 A connecting pipe 3 is inserted into the bottom end of the sleeve 101, and an external thread is provided on the outer circumferential surface of the connecting pipe 3. The connecting pipe 3 is used to connect with an external pipeline, and the diameter of the connecting pipe 3 is smaller than the diameter of the sleeve 101.

[0028] See Figure 3 , Figure 4 The notch on the outer circumference of the cover plate 2 is an anti-slip groove 201, and a sealing ring 202 is fixedly connected to the bottom end of the cover plate 2. The main body of the sealing ring 202 is a ring structure and the sealing ring 202 is made of rubber.

[0029] By fixing a sealing ring 202 to the bottom surface of the cover plate 2, a quick and tight connection can be achieved during use.

[0030] See Figure 1 , Figure 5 The inner side of the four connecting brackets 103 is also fixedly connected to the support base 104, and the main body of the support base 104 is a ring structure.
