Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in Figure 1, the present embodiment wrist-watch returns point gear and comprises: driving wheel 1, engaged wheel parts 2, cam part 4, cam driving wheel backstay 7, cam driving wheel jumper spring 8, lever part 9, sector gear return spring 13 and pointer 22; Driving wheel 1 is arranged on above the movement power output wheel and with the movement power output wheel and is pressed into one; Engaged wheel parts 2 are pressed into one by engaged wheel 3 and small bit nail 14 and mesh with driving wheel 1, and following closely 17 with the position under the driving of driving wheel 1 is the turning axle rotation; Cam part 4 is pressed into one by cam driving wheel 5, cam 6 and small bit nail 15, and the gear teeth of cam driving wheel 5 are stirred by the small bit nail on the engaged wheel parts 2 14, is the turning axle rotation thereby drive cam part 4 with screw 19; One end of cam driving wheel backstay 7 can be the turning axle rotation by position nail 18, and its other end is pressed on the gear teeth of cam driving wheel 5 cam part 4 is located; Cam driving wheel jumper spring 8 is installed in the movement clamping plate groove, relies on movement cover plate (not shown) to fix, for cam driving wheel backstay 7 provides restoring force; Lever part 9 is pressed into one by lever 10, sector gear 11 and small bit nail 16, and the tip of lever 10 is pressed in the external peripheral surface of cam 6, and relying on the lift promotion lever part 9 of cam 6 is that turning axle rotates with screw 20; Needle pivot 12 is meshed with sector gear 11, and pointer 22 is pressed together on the needle pivot 12, rotates with needle pivot 12; Sector gear return spring 13 is fixed on the movement clamping plate by screw 21, and the one end is pressed in sector gear 11 1 sides, for sector gear 11 provides restoring force.
The course of work that the present embodiment wrist-watch is returned point gear is illustrated below:
As shown in Figure 1, under the state, travel time system drives driving wheel 1 rotation to wrist-watch when normally walking, and engaged wheel parts 2 are the turning axle rotation with position nail 17 under the driving of driving wheel 1; Small bit nail 14 on the engaged wheel parts 2 is stirred the gear teeth of cam driving wheel 5, and driving cam part 4 is the turning axle rotation with screw 19; It is that turning axle rotates with screw 20 that cam part 4 relies on the lift of cam 6 to promote lever part 9; Sector gear 11 on the lever part 9 drives needle pivot 12 rotations, drives pointer 22 and rotates together.
As shown in Figure 2, because the lift of cam 6 is limited,, and also can only rotate to an angle with the needle pivot 12 of lever part 9 engagements so lever part 9 can only rotate in the certain angle scope.When cam part 4 reached maximum lift, the needle pivot 12 that drives by lever part 9 also reached maximum corner, and pointer 22 indicates the maximum time mark on the fan-shaped dial plate.
As shown in Figure 3, the 6 continuation rotations of cam driving wheel will drive cam part 4 and reach the lift minimum point rapidly, slide to the concave point of cam 6 rapidly at the tip of the lever 10 of lever part 9 thereupon, under the effect of sector gear return spring 13, sector gear 11 rapid backward rotation, thus drive needle pivot 12 rapid backward rotation, make pointer 22 turn back to reference position and indicate minimum time mark on the fan-shaped dial plate, like this, just finished the indication that returns of pointer 22.
Said process constantly repeats, and the present embodiment wrist-watch returns point gear i.e. instruction time serially.
