Abstract

The utility model discloses a timer which comprises a mechanical timing machine core, a toggle device and a circuit chip, wherein the mechanical timing machine core thereof is composed of a clamp plate, a great wheel, an alarm wheel, a cam, other wheel trains, a balance wheel, hairsprings and an escapement shifting fork. The utility model is characterized in that the cam is a cylindrical cam provided with a notch, a pair of contact terminals in the toggle device directly adopt corresponding current conducting reeds, stationary reeds are positioned on the inner side of the lower part of the cam, and movable reeds are positioned on the outer side of the lower part of the cam; the contact terminals on the movable reeds follow the rotation of the cam to slide on the surface thereof, and are cut into the notch of the cam to be in short connection with the stationary reeds. The utility model solves the problems of triggering output and the matching of the current conducting reeds and the cam, contact performance is completely and reliably improved, and the utility model is suitable for various travel timers with an audible signal as a prompt.

Description

Imitative sound reminiscences

Technical field

The utility model belongs to alarm clock, particularly utilize acoustics circuit chip drives sounding remind or report to the police walk the time time set.

Background technology

The prior mechanical time set is equipped with back of the body bell, gives the correct time with the tinkle of bells, and it is stiff that sound seems; And the sound equipment alarm set has had application widely in alarm, often with music, the different imitative acoustic alarms (informing) with other of voice.Both can organically combine fully, are reasonably designed and improve, obtain serviceability more stable walk the time time set and category more varied and colorful product come.

Summary of the invention

The purpose of this utility model is the imitative sound reminiscences that time set in the time of will providing a kind of utilization to walk, touch device combine with the acoustics circuit chip.

Imitative sound reminiscences of the present utility model, it is characterized in that: it comprises mechanical type timing movement, touch device, circuit chip, its mechanical type timing movement is mainly by clamping plate, walk great wheel, wheel makes a noise, cam and other train, escapement, hairspring and escapement shift fork are formed, described cam is notched cylindrical cam, a pair of contact in the touch device directly adopts corresponding conductive reed, static contact spring piece is positioned at the inboard of cam below, movable contact spring is positioned at the outside under the cam, the cam operation is holding movable contact spring, at the contact place of the corresponding movable contact spring of cam notch, this movable contact spring contact incision and corresponding static contact spring piece be short circuit mutually.

In the described conductive reed, the contact of movable contact spring is a bending shape, the bending bottom is corresponding with static contact spring piece, slide along cam face in bending top, the shape of kink and cam notch adapt to, contact with static contact spring piece in the gap portions incision, the conductive reed leading foot is access to imitative acoustic-electric road chip and sound-producing device.

Described mechanical type timing movement, its clamping plate are consistent with the maximum physical dimension of movement.

Imitative sound reminiscences of the present utility model after integrating, has improved performance and quality on the whole, has reduced cost.Again owing to adopted notched cylindrical cam, given prominence to cooperating and co-ordination of conductive reed and cam notch, make contact performance bring up to the reliable degree of complete stability.In addition, select the circuit chip of imitative sound for use, effect is better.This device is applicable to various time sets during with the walking of acoustic signal prompting.

Embodiment

In conjunction with the accompanying drawings embodiment is illustrated.

Fig. 1,2,3 is depicted as imitative sound reminiscences embodiment of the present utility model.It comprises mechanical type timing movement, touch device 13, circuit chip 20, its mechanical type timing movement is by clamping plate 1, walk great wheel 2, wheel 12 makes a noise, cam 11 and other train (5,4,3,9), escapement 7, hairspring 8 and escapement shift fork 6 are formed, described cam 11 is the cylindrical cam of band breach 14, a pair of contact in the touch device directly adopts corresponding conductive reed, static contact spring piece 15 is positioned at the inboard of cam 11 belows, movable contact spring 16 is positioned at the outside under the cam 11, holding movable contact spring 16 during cam rotation separates its contact, at cam notch 14 places, incision of the contact of movable contact spring and corresponding static contact spring piece 15 short circuits.The 10th, locating wheel.

In the pair of conductive reed, the contact of movable contact spring 16 is a bending shape, the bending bottom is corresponding with static contact spring piece 15, slide along cam face in bending top, the shape of kink 17 and cam notch 14 adapt to, in the oblique progressively incision of gap portions and static contact spring piece automatic Elastic Contact under the elastic force effect, conductive reed leading foot 19 is access to imitative acoustic-electric road chip 20 and sound-producing device.The 18th, the holder of touch device is provided with screw hole and positioning convex above.

Fig. 3 expresses the relation of conductive reed structure and cam with three-dimensional viewpoin.Cam 11 is with walking great wheel, noisy wheel rotation, and cam face heads on movable contact spring 16, and its kink that serves as contact separates with static contact spring piece 15, because of the breach 14 of elastic force effect incision cam indent, contacts with static contact spring piece 15 when kink arrives shown position.

During work, the great wheel axle is walked in rotation, and noisy wheel just turns over an angle corresponding with timing time, and the while breach of cam withdraws from, the contact of movable contact spring along the breach inclined-plane by outside push up, separate with static contact spring piece.After letting go, escapement starts immediately, the work of escapement shift fork, and train 5-4-3-9 operation, when walking, the cam revolution.Walking great wheel inwardly changes mutually with the wheel that makes a noise, and till the locking, operation stopped when the pointed tooth of taking turns to making a noise withstood.Contact before the locking on the movable contact spring falls into the breach of cam earlier, contact with static contact spring piece, thereby connects the chip power path, or make the trigger end ground connection of circuit chip and trigger circuit work drives Yang Shengqi, sends imitative sound to ring warning, plays the prompting effect.The mechanical type movement has two circular clamping plate up and down, and train is contained in therebetween, and it is approaching consistent with the maximum physical dimension of movement to get its clamping plate (two clamping plates up and down), so both has been convenient to install, and helps again from periphery protection movement member.

Imitative sound reminiscences of the present utility model, working stability is reliable, and its mechanical type timing movement is a general part, uses wide.Timing time is different with different structure, and this routine timing is set can reach two hours.
