Description

Technical Field

[0001] This utility model relates to the field of temperature sensor technology, specifically a telescopic 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 and come in a wide variety. They can be broadly classified into two categories based on the measurement method: contact and non-contact. Based on the sensor materials and electronic component characteristics, they are further divided into resistance temperature detectors (RTDs) and thermocouples.

[0003] When users cook on a hot plate, a temperature sensor needs to be installed underneath the hot plate to detect its temperature. In existing flat-plate cooking utensils, a fixed temperature sensor is usually installed, and the hot plate contacts the temperature sensor for detection. However, since the hot plate often needs to be removed for cleaning, the fixed temperature sensor is easily damaged when the hot plate is reassembled. Utility Model Content

[0004] The purpose of this invention is to provide a telescopic temperature sensor that has the advantages of free extension and retraction and automatic wire management, thus solving the problem that current temperature sensors cannot extend or retract.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a telescopic temperature sensor, comprising a sensor body, a telescopic mechanism connected to the bottom end of the sensor body, an adjustment mechanism provided on the outer edge of the telescopic mechanism, and a power supply mechanism electrically connected to the sensor body inside the telescopic mechanism, the telescopic mechanism comprising a sleeve rod, the top end of the sleeve rod being fixedly connected to the bottom end of the sensor body, and a sleeve being slidably sleeved on the bottom end, the adjustment mechanism comprising a first limiting ring placed in the middle of the outer edge of the sleeve rod, a second limiting ring installed below the first limiting ring, and the second limiting ring being placed at the bottom of the outer edge of the sleeve.

[0006] Preferably, the first limiting ring and the second limiting ring are connected together to a long plate. The long plate is placed outside the telescopic mechanism, and the top end of the adjusting mechanism is fixedly connected to the bottom end of the first limiting ring. The bottom end of the long plate passes through the second limiting ring and extends out of the lower end surface of the second limiting ring. The bottom end of the long plate is constructed with a gripping part. The outer edge surface of the second limiting ring is spirally connected with a lifting eye bolt that passes through the second limiting ring and abuts against the outer edge surface of the long plate.

[0007] Preferably, the cross-section of the long plate is arc-shaped, and the length of the long plate extending beyond the lower end face of the second limiting ring is less than the length of the sleeve rod sliding inside the sleeve.

[0008] Preferably, the power supply mechanism includes an electric wire, the upper section of which is placed inside the sleeve rod and the lower section is placed inside the sleeve, and a plurality of retraction mechanisms are equidistantly installed on the outer edge of the electric wire inside the sleeve.

[0009] Preferably, each of the retraction mechanisms includes a ring, with long rods rotatably mounted at both ends of the ring. The long rods are rotatably connected to the inner edge of the sleeve. A plurality of balls are fitted inside the ring, and both ends of the inner edge of the ring are provided with a chamfering structure. The outer edge of each ball abuts against the outer edge of the wire.

[0010] Preferably, a first torsion spring and a second torsion spring are alternately sleeved on the outer edge of several of the retraction mechanisms from bottom to top, wherein the helical directions of the first torsion spring and the second torsion spring are opposite, and both ends of the first torsion spring and the second torsion spring are respectively fixedly connected to the retraction mechanism and the inner edge of the sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model comprises a sensor body, a sleeve, a first limiting ring, a second limiting ring, a long plate, a grip, and a lifting eye bolt. The sensor body is connected to the top of the sleeve, which slides inside the sleeve. The top of the long plate, which is slidably connected to the second limiting ring, abuts against the first limiting ring, pushing the long plate to move the first limiting ring up and down, changing the length of the sleeve and the sleeve. The lifting eye bolt is fixed to the side of the long plate, thus completing the telescopic displacement of the sensor body and achieving the purpose of telescopic temperature sensor. This facilitates the retraction and protection of the temperature sensor when cleaning iron plates.

[0013] 2. This utility model incorporates an electric wire, a ring, a long rod, a ball bearing, a first torsion spring, and a second torsion spring. The ring is fitted around the outside of the electric wire, and the ball bearing abuts against the outer edge of the electric wire to reduce friction. The first and second torsion springs, fitted onto the long rod, cause the adjacent rings to rotate in opposite directions around the axis of the long rod, thereby causing the electric wire to bend into an S-shape inside the sleeve. This completes the storage of the electric wire when the sensor body retracts, facilitating the storage of the electric wire when the temperature sensor retracts. Attached Figure Description

The telescopic mechanism 2 includes a sleeve 21, the top end of which is fixedly connected to the bottom end of the sensor body 1, and a sleeve 22 slidably sleeved on the bottom end. The adjustment mechanism 3 includes a first limiting ring 31 located in the middle of the outer edge of the sleeve 21, a second limiting ring 32 installed below the first limiting ring 31, and the second limiting ring 32 located at the bottom of the outer edge of the sleeve 22. The first limiting ring 31 and the second limiting ring 32 are connected together to a long plate 33, which is located outside the telescopic mechanism 2. The top end of the adjustment mechanism 3 is fixedly connected to the bottom end of the first limiting ring 31, and the bottom end passes through the second limiting ring 32 and extends out of the lower end surface of the second limiting ring 32. The bottom end of the long plate 33 is constructed with a gripping part 34. A lifting eye bolt 35, which passes through the second limiting ring 32 and abuts against the outer edge of the long plate 33, is spirally connected to the edge. The long plate 33 has an arc-shaped cross-section, and the length of the long plate 33 extending beyond the lower end face of the second limiting ring 32 is less than the length of the sleeve rod 21 sliding within the sleeve 22. The power supply mechanism 4 includes a wire 41, the upper section of which is placed inside the sleeve rod 21, and the lower section is placed inside the sleeve 22. Several retraction mechanisms 5 are equidistantly installed on the outer edge of the wire 41 inside the sleeve 22.

[0025] Working principle: In the operation of this utility model, the top of the long plate 33, which is slidably connected by the second limiting ring 32, abuts against the first limiting ring 31, pushing the long plate 33 to drive the first limiting ring 31 to move up and down, changing the length of the sleeve rod 21 and the sleeve 22, thus completing the extension and retraction of the sensor body 1. The ring 51 is sleeved on the outside of the wire 41, and the ball bearing 53 abuts against the outer edge of the wire 41 to reduce friction. Through the first torsion spring 6 and the second torsion spring 7 sleeved on the long rod 52, the adjacent ring 51 is driven to rotate in opposite directions around the axis of the long rod 52, thereby causing the wire 41 to bend into an S-shape inside the sleeve 22, thus completing the storage of the wire 41 when the sensor body 1 is retracted.
