Abstract

The invention discloses a starting mechanism with an insurance device; an insurance starting shifting block is arranged on a wheel sheet; a first lever is in screw connection with an insurance rod part, and the first lever and the insurance rod part can rotate around a rotation center; one end of the first lever contacts with or disengages from one end of a second lever, the other end of the first lever contacts with or disengages from a starting position screw of the wheel sheet, the other end of the second lever abuts against or disengages from a starting wheel assembly; the insurance starting shifting block contacts with or disengages from one end of the insurance rod part, the other end of the insurance rod part contacts with or disengages from the starting wheel assembly. The beneficial effects are that the insurance device is added, starting is accurate, so the device can be applied in the precision machine control fields like an instantaneous jump perpetual calendar on a machinery watch, calendar changing motion can be timely started and is accurate, thereby preventing multi-calendar changes caused by massive energy, and movement work stability is improved; the starting mechanism with the insurance device is reliable in operation, easy in assembling, good in techniques, and low in processing precision requirement.

Description

technical field [0001] The invention relates to a starting mechanism, in particular to a starting mechanism with a safety device. Background technique [0002] The starting structure is widely used in the mechanical industry and is an indispensable part of the mechanical structure. The so-called starting structure is the key structure that closely links the starting command and the action to be started, which directly affects the accuracy of the starting action. For example: the timekeeping structure in the watch, the sound made at the hour or the action of the puppet, all of which need to be activated by the activation structure, and the function of the insurance is to ensure that the activated actions can occur according to the established rules. For example: the length of a watch chime or the number of puppet movements, these are strictly enforced through the activation structure. However, the existing starting structure has very high requirements on the interaction...
