Abstract

The utility model relates to an alarm mechanism without restricted area of set hand. An alarm disk 1 with helical teeth 7 is sheathed on an alarm wheel 2, which is sheathed on an hour wheel 5 or an alarm wheel 11. The helical teeth 7 are matched with the bend holes 6, 9 and 12 of the alarm wheel 2, or the hour wheel 5 or the alarm wheel 11. The structure can solve the problem of restricted area of set hand existing in the field of clocks for a long time. No matter when the alarm stops or starts, the clock hand can be arranged in clockwise or anti-clockwise direction without being limited by restricted area of set hand during time or alarm setting, which also avoids the axial jump of the alarm hand during alarming without affecting service life of the clock. Moreover, the utility model satisfies the developing requirements of minimization of clocks.

Description

The alarm mechanism of no restricted area

The utility model relates to a kind of clock and watch alarm mechanism of no restricted area.

China's structure of making a noise from the side that the N1 type of sixties production is unified the movement mechanical alarm clock exists the problem of restricted area always, and promptly alarm mechanism is opened in a period of time after making a noise and is merely able to clockwise proof time, and can only proofread out counterclockwise and make a noise constantly.If dial counterclockwise at the time, the alarm hand of having proofreaded is rotated together with hour hands, confound easily when making a noise constantly; If dial clockwise and make a noise then dial motionlessly, then can damage parts if firmly dial.The alarm spring of the quartz clock of the alarm mechanism of imitative in recent years NSK house company is between hour wheel and minute wheel, though can solve the restricted area problem that the structure of making a noise is opened at this a kind of center, but be confined to alarm spring between hour wheel and the axial position of minute wheel sheet, and play the noisy a kind of center that is enclosed within on the hour wheel of coiling and open noisy structure.Open noisy alarm mechanism and various side structure when making a noise structure noisy for the center of alarm spring between hour wheel and dial plate, also all have restricted area so far, this type of problem not can solve always.

The purpose of this utility model will overcome the described deficiency of background technology exactly, and proposes a kind ofly no matter to open the alarm mechanism that all there are not restricted area in make a noise structure or the other clock and watch that make a noise structure for the center.

The technical solution that realizes above-mentioned purpose is:

The alarm mechanism of this no restricted area comprises alarm spring, rises to make a noise and coil, make a noise wheel, hour wheel or alarming wheel, working the dish that makes a noise is enclosed within on the wheel that makes a noise, noisy wheel is enclosed within again on hour wheel or the alarming wheel, alarm spring has been pressed on the end face of the dish that makes a noise, work the dish that makes a noise and go up the end face that the inclined-plane of helical teeth has originated in the dish that makes a noise, the curved hole that has on helical teeth and noisy wheel, hour wheel or the alarming wheel cooperates, and the end in curved hole is provided with the slope.The number of helical teeth is identical with the number in curved hole, and the radian of helical teeth and the radian in curved hole adapt.The several helical teeth that rise on the dish that makes a noise have semidiameter mutually.Also be provided with curved hole and slope on the alarming wheel.

Now in conjunction with the accompanying drawings the utility model is done an explanation.

Fig. 1 shows center of the present utility model and opens noisy structure.Have the noisy dish 1 of rising of end face helical teeth 7 (referring to Fig. 2, Fig. 3) and be sleeved on the static noisy wheel 2 (referring to Fig. 4,5), alarm spring 4 has been pressed in the end face of the dish 1 that makes a noise.The wheel 2 that makes a noise is sleeved on the hour wheel 5 (referring to Fig. 6,7), hour wheel 5 again with split axle 3 suits.Rise making a noise, helical teeth 7 all has radian on the dish 1, and between each helical teeth 7 semidiameter is arranged all.The curved hole 6,9 that is respectively equipped with on wheel 2, the hour wheel 5 of making a noise and adapts with the helical teeth 7 of radian, and the end in each curved hole 6,9 all designs a slope 8,10.

Clock and watch for the noisy structure in side are provided with the curved hole 12 (referring to Fig. 8,9,10) that an end has slope 13 too on alarming wheel 11, work the dish 1 that makes a noise and be sleeved on the alarming wheel 11, and alarm spring 4 has been pressed in to make a noise and has coiled on 1.Open when making a noise, work the helical teeth 7 of the dish 1 that makes a noise and fall in the curved hole 6 of the wheel 2 that makes a noise, alarm spring 4 suppresses downwards and makes it break away from bell clapper bar 14 when making clock and watch begin to make a noise.

Described the one side of coiling helical teeth 7 on 1 of making a noise is the right angle, and another side is an inclined-plane, and the starting point on this inclined-plane should be begun by an end face that works the dish 1 that makes a noise.At ordinary times, wheel 2 transfixions of making a noise, and alarm mechanism has only hour wheel 5 or alarming wheel 11 rotating.Alarm mechanism is closing when making a noise, and the rotation train is not interfered between the wheel 2 with making a noise, so does not have restricted area.Alarm mechanism open make a noise during, when clockwise direction is dialled the timing pointer or is counterclockwise dialled the alarm hand rotation, helical teeth 7 all can be along the slope 10 of an end of the curved hole 9 on the hour wheel 5 of correspondence or the wheel 2 that makes a noise or 6 or 8 and upwards slide onto gradually and slide on its end face, thereby the train of rotation and the not interference between the wheel 2 of making a noise, thereby there is not restricted area yet; Alarm mechanism open make a noise during, when counterclockwise dialling rotation of timing pointer or clockwise direction and dial the alarm hand rotation, curved Kong Yiduan on noisy wheel 2 or the alarming wheel 11 produces the component effect of reacting force to the inclined-plane of helical teeth 7, helical teeth 7 is risen to make a noise on the end face of wheel 2 or alarming wheel 11 and slide, make the rotation train again and the not interference between the wheel 2 of making a noise, thereby also do not have restricted area.

The utility model has been done corresponding improvement on the basis of existing technology, has adopted noisy dish, alarm wheel, hour wheel Or the alarm mechanism of alarming wheel and alarm spring composition, can make various centers open the noisy and other clock and watch that make a noise structure does not have Forward and reverse restricted area, what solved that clock and watch circle exist for a long time always has restricted area during making a noise opening Technical problem has avoided the mistake pulling needle to cause the damage and fracture of member, has improved reliability, has made things convenient for and has used also But the thickness of attenuate clock and watch is to satisfy the requirement of slimming.
