Description

Technical Field

[0001] This utility model relates to the field of platinum resistance sensors, specifically a platinum resistance sensor with good safety performance. Background Technology

[0002] Platinum resistance thermometers primarily detect temperature by detecting platinum resistance elements. These elements utilize the property that the resistance of platinum metal changes with temperature to measure temperature. As temperature changes, the resistance of the platinum resistance element changes; by measuring this change, the temperature can be determined. However, existing platinum resistance sensors lack protective structures at the connection between the probe and the lead wire, leaving it exposed and susceptible to damage from impacts. This results in low safety, unstable connections that affect measurement data, and negatively impact user experience. Therefore, we propose a platinum resistance thermometer with improved safety performance. Utility Model Content

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] This embodiment is a platinum resistance sensor with good safety performance.

[0021] like Figure 1-4As shown, the device includes a probe 1, a wire 2 at the lower end of the probe 1, a connector 3 on the upper outer surface of the wire 2, and a protective mechanism 4 on the outside of the probe 1. The protective mechanism 4 includes a limiting sleeve 5, a slot 6, a protective ring 7, a semi-ring plate 8, a threaded ring 9, a limiting plate 10, an anti-slip plate 11, a keyway 12, a key rod 13, a threaded groove 14, and a groove 15. The limiting sleeve 5 is located outside the probe 1. The slot 6 is opened on the upper outer surface of the limiting sleeve 5. The protective ring 7 is located on the lower outer surface of the limiting sleeve 5. The groove 15 is opened on the lower outer surface of the protective ring 7. Two sets of semi-ring plates 8 are located on both sides of the lower end of the protective ring 7. The threaded ring 9 is located on the upper end of the inner surface of one side of the semi-ring plate 8. The limiting plate 10 is located on the lower end of the inner surface of one side of the semi-ring plate 8. The anti-slip plate 11 is located on the upper outer surface of the limiting plate 10.

[0022] Two sets of key rods 13 are located at the front end of one side of the outer surface of the limiting plate 10 and the rear end of the other side of the outer surface of the limiting plate 10, respectively; two sets of keyways 12 are respectively opened at the rear end of one side of the outer surface of the limiting plate 10 and the front end of the other side of the outer surface of the limiting plate 10, and threaded grooves 14 are opened on the inner wall of the protective ring 7; the limiting sleeve 5 is sleeved with the probe 1 through the hole groove 6, and the key rods 13 and keyways 12 are inserted; the threaded ring 9 and threaded grooves 14 are threaded.

[0023] It should be noted that this utility model is a platinum resistance sensor with good safety performance. By fitting the limiting sleeve 5 onto the lower end of the outer wall of the probe 1 through the slot 6, the two sets of semi-ring plates 8 are moved to both sides of the wire 2. After the two sets of semi-ring plates 8 are connected by the key rod 13 and the keyway 12, the two sets of semi-ring plates 8 are spliced ​​together. The keyway 12 and key rod 13 on one side of the limiting plate 10 are respectively arranged in one set with the key rod 13 in front and the keyway 12 behind, and the other set with the keyway 12 in front. With rod 13 at the rear, hold the semi-ring plate 8 and align it with the groove 15. Then rotate the semi-ring plate 8 to connect it to the threaded groove 14 via the threaded ring 9. As the semi-ring plate 8 rises, the anti-slip plate 11 on the upper end of the limiting plate 10 moves to the lower end of the connector 3, bringing the anti-slip plate 11 into contact with the connector 3 and limiting its position. This facilitates the limiting and fixing of the connector 3, improves its stability, and provides protection for the connector 3, thus enhancing its safety.
