Description

TECHNICAL FIELD

[0001] The utility model relates to thermometer production technical field, especially the temperature sensing piece's sleeve mould device of pointer type thermometer. BACKGROUND

[0002] The temperature sensing piece of pointer type thermometer includes a coil spring piece and a pointer shaft connected to the coil spring piece, and the pointer shaft refers to a component for connecting a pointer. The working principle of the pointer type thermometer is that the coil spring piece will be elastically deformed to different degrees at different temperatures, thereby driving the pointer shaft to rotate, and thereby driving the pointer to point to different temperature scales.

[0003] The processing procedure of the temperature sensing piece of the pointer type thermometer is as follows: the pointer shaft is fixed to the coil spring piece (at this time, the coil spring piece is in a non-coiled state, which can be referred to as a coil spring pointer piece) → the coil spring piece is wound around a coil spring shaft and placed in a mold (the mold is in a cylindrical shape and is used to maintain the coiled state of the coil spring piece) → high-temperature process treatment (after the high-temperature process treatment, the coil spring piece for the thermometer is shaped to a "coiled" state, and its elastic performance meets the requirements of temperature measurement).

[0004] Note: After heat treatment, the temperature sensing piece of the pointer type thermometer is pulled out of the mold cylinder for the production of thermometers.
