Description

Technical Field

[0001] The utility model relates to the technical field of temperature transmitters, in particular to a split-type temperature transmitter. Background Art

[0002] Temperature transmitter is a device that converts the signal of temperature sensor into current signal, connects it to secondary instrument, and thus displays the corresponding temperature. It is widely used in industrial fields such as petroleum, chemical, chemical fiber, textile, rubber, building materials, metallurgy, medicine and food.

[0003] Among them, temperature transmitters are often divided into integrated economical temperature transmitters and split temperature transmitters. However, the tube body of the integrated economical temperature transmitter is fixed and straight, but the height cannot be adjusted. When there are gas pipelines above some pipelines or the height display is not enough to be difficult to view, an extension tube will be installed.

In the process of the support column retracting into the support tube, the positioning ring can be driven to reverse by the elastic force of the torsion spring, so that the cooperation between the positioning hole and the wire drives the wire to be rewound around the positioning column, thereby realizing the extension and rewinding of the wire, thereby avoiding the occurrence of tangling of the wire. At the same time, the support tube can protect the wire.

[0036] 3. In the present invention, through the arrangement of the thermometer, the support column, the support tube, the support plate, the connecting mechanism and the positioning mechanism, it is convenient to adjust the height of the thermometer by rotating the hand wheel.

[0047] Specifically, during the movement of the support column 3, the wire 11 can be pulled to move, thereby driving the positioning ring 10 to rotate through the cooperation between the wire 11 and the positioning port, so that the wire 11 wrapped around the positioning column 8 is extended from the positioning port, thereby ensuring the electrical connection between the temperature sensing element 6 and the thermometer 1. In the process of the support column 3 retracting into the support tube 4, the positioning ring 10 can be reversed through the elastic force of the torsion spring 12, so that the cooperation between the positioning port and the wire 11 drives the wire 11 to be rewound around the positioning column 8, thereby realizing the extension and reeling of the wire 11, thereby avoiding the occurrence of knots in the wire 11, and at the same time, the wire 11 can be protected by the support tube 4.

A connecting rod is fixedly set between the handwheel 21 and the second bevel gear 20, and the side wall of the handwheel 21 is provided with anti-slip grooves.

[0049] Specifically, the operator can pull the thermometer 1 so that the support column 3 moves in the support tube 4 to adjust the height of the thermometer 1. After pulling it to the appropriate height, the operator turns the handwheel 21, and the rotation of the handwheel 21 can drive the second bevel gear 20 to rotate. At the same time, the engagement of the second bevel gear 20 with the first bevel gear 19 drives the first bevel gear 19 and the threaded rod 17 to rotate, and the threaded cooperation of the threaded rod 17 and the adjusting disk 15 drives the adjusting disk 15 to move. During the movement of the adjusting disk 15, the positioning plate 14 can be pushed by the adjusting plate 16 to adjust the angle, and then the positioning block 13 can be driven to squeeze the side wall of the support tube 4 through the angle adjustment of the positioning plate 14, so that the positioning between the support column 3 and the support tube 4 can be achieved by squeezing the side wall of the support tube 4 by the positioning block 13, thereby achieving the adjustment of the height of the thermometer 1.

[0050] In this embodiment, when in use, the operator can pull the thermometer 1 so that the support column 3 moves in the support tube 4 to adjust the height of the thermometer 1. After pulling it to a suitable height, the operator turns the handwheel 21, and the rotation of the handwheel 21 can drive the second bevel gear 20 to rotate. At the same time, the engagement of the second bevel gear 20 with the first bevel gear 19 drives the first bevel gear 19 and the threaded rod 17 to rotate. The threaded cooperation between the threaded rod 17 and the adjusting disk 15 drives the adjusting disk 15 to move. During the movement of the adjusting disk 15, the positioning plate 14 can be pushed by the adjusting plate 16 to adjust the angle. The positioning block 13 is driven to squeeze the side wall of the support tube 4 through the angle adjustment of the positioning plate 14, so that the squeezing of the side wall of the support tube 4 by the positioning block 13 can be achieved. The positioning between the support column 3 and the support tube 4 is achieved, and then the height of the thermometer 1 is adjusted. During the movement of the support column 3, the wire 11 can be pulled to move, so that the positioning ring 10 is driven to rotate through the cooperation between the wire 11 and the positioning port, so that the wire 11 wrapped around the positioning column 8 is extended from the positioning port, thereby ensuring the electrical connection between the temperature sensing element 6 and the thermometer 1. In the process of the support column 3 retracting into the support tube 4, the positioning ring 10 can be driven to reverse through the elastic force of the torsion spring 12, so that the cooperation between the positioning port and the wire 11 drives the wire 11 to be rewound around the positioning column 8, thereby achieving the extension and reeling of the wire 11, thereby avoiding the occurrence of knots in the wire 11. At the same time, the wire 11 can be protected by the support tube 4.
