Automatic winding device of mechanical clock

Abstract

The invention discloses an automatic mechanical clock winding device, which comprises a mainspring shaft gear arranged in a clock body, a temperature-sensitive memory metal bar which can sense temperature changes and stretch or reduce in accordance and is arranged in the clock body, and a unidirectional pushing device which forces the mainspring shaft gear to rotate in one direction and is arranged between the temperature-sensitive memory metal bar and the mainspring shaft gear. The device of the invention can not only be applicable to automatic winding of mechanical clocks in working state but also be applicable to automatic winding of mechanical clocks in idle state.

Description

technical field [0001] The invention relates to the technical field of clocks and watches, in particular to an automatic winding device for mechanical clocks used for winding the mainspring of the mechanical clocks. Background technique [0002] At present, most of the ordinary mechanical clocks and watches used by people's doors must be wound manually at regular intervals to maintain their normal operation. The mechanical automatic winding system uses a metal oscillating weight inside the clock. Its operating principle is to use the movement of the wearer's arm to make the metal oscillating weight in the automatic system swing due to the gravity of the earth, and the metal oscillating weight does not rotate at all. Thereby pushing the levers and gears in the system to wind up the mainspring, so it can be seen that this automatic winding system is only suitable for watches. inapplicable. Contents of the invention [0003] The technical problem to be solved by the present...
