Embodiment 1
[0019] The regional clock movement of embodiment 1 of the present invention (referring to figure 1 ), it is a clock movement designed and improved based on the movement used in the three-pin sub-clock of the intelligent sub-master clock system that is suitable for public places such as ships, hotels, stations, and docks and is used for unified control in this area. The clock movement in this area mainly includes: the front splint 3 and the middle splint 1 of the movement form the supporting frame of the gear train transmission shaft of the clock movement, the stepping motor 2 is fixedly installed on the middle splint 1, and the output of the stepping motor 2 The gear at the end is meshed with the large gear of the gear reduction transmission assembly 4, and the pinion of the gear reduction transmission assembly 4 is directly meshed with the minute wheel 6 fixedly installed on the minute wheel shaft 10. This structure is formed by the stepping motor 2 to The two-stage 12:1 gear...
Embodiment 2
[0021] The regional clock movement of embodiment 2 of the present invention (referring to figure 1), it is a clock movement designed and improved based on the movement used in the three-pin sub-clock of the intelligent sub-master clock system that is suitable for public places such as airports, subways, and high-speed rails and used within a certain area. The technical requirements of the movement are: accurate travel time, hour and minute hand calibration, fast dialing does not affect the operation of the second hand, the second hand operates in a continuous movement mode, and the second hand and the minute hand run in full minutes and zero seconds. For this reason, except that the technical solution set in this embodiment 2 is completely the same as the technical solution described in embodiment 1 of the present invention, it also has the following differences: one is to further meet the technical requirements of this embodiment, the described The synchronous geared motor 16...
