Embodiment

Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.

Referring to Fig. 1 and Fig. 2, a kind of music timer movement, comprises timer module 1 and music module 2.Wherein timer module 1 comprises train wheel bridge 11 and lower plate 12, and train wheel bridge 11 and lower plate 12 center are provided with away an axle 13, and noisy axle 14 is arranged on train wheel bridge 11, and an axle 13 is parallel with walking.Walk to be provided with on an axle 13 and walk great wheel 131 with what walk that an axle 13 rotates, on noisy axle 14, be provided with alarm wheel 141, walk great wheel 131 and alarm wheel 141 engagements arrange, other trains are arranged between train wheel bridge 11 and lower plate 12.Above-mentioned parts are identical with the mechanical timer movement of prior art, do not repeat them here.

Music module 2 comprises fixed head 21, and it is fixed on train wheel bridge 11 tops or lower plate 12 belows, and size is also approximate with train wheel bridge 11 or lower plate 12.Fixed head 21 is provided with music wiring board 22, and the hummer 23 of being controlled by music wiring board 22 is the power supply unit 24 of music wiring board 22 power supplies.

Also comprise the switch element of controlling music wiring board 22 conductings or disconnection, comprise the cam 15 being arranged between alarm wheel 141 and train wheel bridge 11, the periphery of cam 15 is provided with universal driving shaft 151 straight up, and on the periphery of alarm wheel 141, offer the perforation 142 of mating with universal driving shaft 151, universal driving shaft 151 is through perforation 142, thereby when alarm wheel 141 is rotated, cam 15 also rotates thereupon.

Between train wheel bridge 11 and lower plate 12, be fixed with static contact spring piece 16, and one end of movable contact spring 17, the other end of movable contact spring 17 is corresponding with static contact spring piece 16 positions, can contact or leave static contact spring piece 16 with static contact spring piece 16.On the periphery of cam 15, offer the first breach 152, on the periphery of train wheel bridge 11, offer the second breach 111, movable contact spring 17 inner sides are provided with the push rod 18 being rotationally connected with train wheel bridge 11 or lower plate 12, push rod 18 is located in the second breach 111 and extends upward the height over cam 15, with the periphery of cam 15 and the medial surface butt of movable contact spring 17.The stiff end of movable contact spring 17 and static contact spring piece 16 are connected to respectively the two ends of music wiring board 22 by wire 24, after controlling its conducting or disconnect.

The course of work of music timer movement of the present utility model and principle are:

First, by rotation, walk the timing that an axle 13 sets requirement, through walking great wheel 131, drive alarm wheel 141 to rotate, the cam 15 of alarm wheel 141 belows rotates thereupon thus, the periphery of cam 15 withstands push rod 18, and push rod 18 pushes up movable contact spring 17 laterally thus, and the movable end of movable contact spring 17 does not contact with static contact spring piece 16, the 22 not conductings of music wiring board, referring to Fig. 3, when alarm wheel 141 is covered timing and is got back to zero point, the first breach 152 of cam 15 forwards the position corresponding with the first breach 111 to, thus, push rod 18 no longer enters in the first breach 152 with the periphery butt of cam 15, thereby no longer movable contact spring 17 is applied to power laterally, when not being subject to push rod 18 thrust, the movable end of movable contact spring 17 under elastic-restoring force effect, do not reset to the inside, contact with static contact spring piece 16 thus, now music wiring board 22 is connected, make hummer 23 send music tone ringer, referring to Fig. 4, this music tone ringer can be to crow, bark, doorbell sound, musical sound or other any the tinkle of bells of recording.

The foregoing is only preferred implementation of the present utility model; it should be pointed out that for the ordinary skill in the art, do not departing under principle prerequisite of the present utility model; can also make various deformation and improvement, this also should be considered as protection domain of the present utility model.
