Abstract

The utility model relates to a mechanical time-giving clock which can be used for time counting, arbitrarily selecting a plurality of moments, and emitting the time-giving bell ring, in terms of a period of time of five minutes within 24 hours. A minute hand shaft (11) is additionally provided with one contact pin wheel (6). The contact pin wheel is meshed with a timing wheel (5) arranged on the movable pendulum shaft (1). The time-giving mechanism is controlled by the pendulum shaft (1), a push spring (2), and an operating rod (8) to operate according to the appointed moment.

Description

Mechanical time-giving clock

The utility model is about a kind of mechanical striking clock, a kind of can be used for timing and can be in 24 hours be level with 5 minutes, send the loud mechanical striking clock of official seal that gives the correct time by selecting a plurality of moment arbitrarily.

Usually used mechanical clock has two kinds of mechanisms of giving the correct time, but a kind ofly is arbitrary timing but can only does disposable (as the alarm clock) that the gives the correct time mechanism of giving the correct time; Another kind is the mechanism of giving the correct time at (as the desk clock) that integral point or the least bit send signal.For some units that needs frequent report time signal, as factory, office, school, these the two kinds mechanisms of giving the correct time are just powerless, in order to grasp and report time, usually will be equipped with the professional.

Mechanical striking clock scheme of the present utility model proposes for addressing this problem.

Mechanical striking clock of the present utility model, timing is partly just the same with the standard machinery clock, it is characterized in that setting up on the minute hand shaft (11) a contact pilotage wheel (6) that 12 contact pilotages are arranged, and making it be contained in the timing wheel (5) that has 288 apertures on the movable balance staff (1) and be meshed with one, the tooth ratio is 25:24.Balance staff (1) is gone up incorporate spring (2) and the operating rod (3) of pushing away, and fine motion spring (10) has been controlled one to be had cam (8) and press the coaxial or interlock of nail (9); The mechanism of giving the correct time of wind wheel or interlock coaxial with control pin (4) makes the moment action that it go up to set by timing wheel (5).

Pointer is position and to refer generally to needle shaft opposite in the table of two needle shafts partly, its shift means is to realize by the conversion of two needle shaft gear front and back positions and the corresponding conversion of back gear (transmitting that gear that the clockwork spring moment of torsion makes the rotation of two pins), comprising the change of two needle shaft diameters.

According to time signal clock of the present utility model, will bring and big convenience for people's work, life, and because it is simple in structure, and production technology is easy, regularly convenient, long service life, and can under various environment, work, be subjected to people's welcome surely.If the power supply signal of this clock is combined with electronic circuit, can use semi-automatic field.

Embodiment accompanying drawings of the present utility model is as follows:

Fig. 1 expresses the design's feature design of part figure partly.

Fig. 2 is the front view of contact pilotage wheel (6).

Fig. 3 is the left view of contact pilotage wheel (6).

Fig. 4 is the left view of timing wheel (5).

Fig. 5 is the cut-open view of timing wheel (5).

Minute hand shaft (11) and contact pilotage wheel (6) is integrated, by contact pilotage wheel (6) interlock be timing wheel (5), be contained on the movable balance staff (1) and the incorporate spring (2) that pushes away of balance staff.Control partly has operating rod (3) and fine motion spring (10).

The mechanism of giving the correct time can be that five gears are formed, have clockwork spring on first gear shaft, second gear hub two ends is cam (8) and the position of pressing nail (9), and third and fourth is transmission gear, and the 5th gear hub two ends are positions of wind wheel and control pin (4).Look from clock face: one, three, five take turns rotation counterclockwise, two, the rotation of four-wheel clockwise direction.The rotating ratio of five gears can be: 1:6:54:360:2400.

Refer now to contact pilotage on the contact pilotage wheel (6) and the aperture relation each other on the timing wheel (5), 12 contact pilotages become circular helix to arrange on wheel, 288 apertures on the timing wheel (5) are divided into 12 weeks 24 row arrangements, and wherein 12 all apertures are relative with 12 contact pilotages.During the hour hands running, contact pilotage always enters aperture and through the point of contact, withdraws from aperture on the point of contact under the point of contact, because the tooth of 25:24 ratio relation, contact pilotage wheel (6) is when up time rotates a circle, and timing wheel (5) inverse time changeed for 1 1/24 weeks.If face end first all 24 apertures are pressed up time direction number consecutively: No. 1, No. 2, No. 3 ... No. 24, during again with hand up time rotation contact pilotage wheel (6) as seen: contact pilotage wheel (6) rotates a circle, with first contact pilotage of face end together through the aperture conversion at point of contact 1 number, if certain phase runs into aperture No. 1, second week just ran into No. 2 aperture mutually, 3 weeks No. 3,4 weeks No. 4 ... 24 weeks No. 24,25 weeks No. 1,26 weeks No. 2 Aperture visible from the point of contact and that contact pilotage meets is made infinite loop from 1 to 24.Contact pilotage wheel (6) changeed for 24 weeks, the chance of 24 each contact pilotages that once meet at the place, point of contact of aperture.

Be the working order of a contact pilotage and 24 apertures of relative that week above, other 11 contact pilotages and institute are also just the same to the working order of 11 all apertures, are at different effluxion point of contacts.So the chance of 288 apertures each contact pilotage that once meets at the point of contact in the time, each aperture can be represented certain regular time in one day, is the time that unit is divided into 288 parts with 5 minutes so just.Give the correct time in certain time if desired, as long as find that aperture that to give the correct time earlier, it is blocked up (clog to scabble with pocket knife again such as an available matchstick and get final product) with straightforward procedure, time is when running to this aperture, contact pilotage can not enter, make timing wheel (5) to left movement, make operating rod (3) to left movement by pushing away the strength that spring (2) overcomes fine motion spring (10), control pin (4) is released, the mechanism's entry into service of giving the correct time, cam (8) is by pressing the power switch official seal sound by arm (7), ring to rotate just and 1 week discharged power switch official seal sound and end, press simultaneously and follow closely (9) and press down and push away spring (2) front end, and be depressed into operating rod (3) always and be released by pressing arm (7) to required time cam (8), the strength of fine motion spring (10) moves right operating rod (3) and pins control pin (4), and the mechanism of giving the correct time shuts down.At this moment press nail (9) to press down certain position pushing away spring (2), owing to push away the camber of spring (2) front end and (1) two factor of balance staff of rear end, make the elasticity strength that pushes away spring (2) convert the strength that balance staff (1) moves right to, but at this moment contact pilotage with closed pores in the position, point of contact, timing wheel (5) can not playback, along with moving on the contact pilotage, balance staff (1) moves right, during to timing wheel (5) playback, press nail (9) and push away spring (2) and throw off automatically, push away spring (2) and go up bullet pinning operating rod (3) and finish once and give the correct time.
