Abstract
The utility model discloses an alarm-setting mechanism of an alarm clock whose alarm-setting hand is outside of a clock dial. The front end of an alarm-setting axis is extended outside the clock dial, and the alarm-setting hand is fixed; an alarm-setting letter disc is cancelled, and because the position of the alarm-setting hand is obvious and is convenient for observing, the utility model overcomes the defect of a general alarm clock that alarming time can only be observed through a small circular arc window on the clock dial. The utility model has the advantages of convenient operation, little possibility of mis-alarm producing, simple and convenient production of alarm-setting hand and cost reducing, making the alarm clock have high quality but inexpensive price.
Description
The utility model belongs to Chronograph timepiece mechanism.
Alarm clock is the clock and watch of using always, and alarm clock sends to make a noise in needs and rings, and wakes heavy sleepers, tells people to arrive the time.The noisy sound of alarm clock has several different methods, adopt the noisy alarm clock that rings of mechanical type that very long history is arranged, system is made up of two parts during general mechanical activation alarm clock noisy, two parts are quarrel and fight noisily mechanism and alarm-setting mechanism, wherein alarm-setting mechanism mainly by alarm-setting axis, to the letter disk that makes a noise, axle sleeve, make a noise wheel, alarm spring, alarm-setting axis spring etc. in addition part constitute, the alarm-setting axis front end is being fixed letter disk and the axle sleeve of making a noise, at rotation alarm-setting axis when making a noise, make a noise letter disk and axle sleeve are also rotated with alarm-setting axis, a breach is arranged on the axle sleeve.The wheel part that makes a noise is enclosed within on the alarm-setting axis versatilely, the wheel that makes a noise meshes with a small over-wheel, the hour wheel engagement of small over-wheel and alarm clock, because the number of teeth is identical, wheel and the hour wheel of making a noise rotated synchronously, also just and the hour hands of alarm clock rotate synchronously, go out a double wedge sheet on the wheel rim of noisy wheel, when the double wedge sheet of the wheel that makes a noise turns to when breach on the axle sleeve overlaps, under the elastic force effect of alarm spring, the wheel that makes a noise moves along alarm-setting axis, and the stopping noisy bar of riveting on alarming buckle decontroled at the alarm spring tip, tighten the mechanism action of quarrelling and fighting noisily of clockwork spring, just sent ring tone.The letter disk that makes a noise is installed in the clock dial rear of alarm clock, one section garden arcuation window is arranged on the clock dial of alarm clock, can see the moment on the letter disk that makes a noise by window, being printed on the arc window of garden makes a noise rings reference point, ring the moment of reference point aiming to make a noise on the letter disk that makes a noise, promptly be the moment that alarm clock makes a noise and rings, manually rotate alarm-setting axis and need just can select the noisy moment of ringing.
The shortcoming of this alarm-setting mechanism is: needing observe by less garden arc window when making a noise, be difficult for seeing clearly the moment on the letter disk that makes a noise, intuitive is poor, the wrong situation of making a noise appears in inconvenient operation easily, and letter disk manufacturing process is many to making a noise, the rejection rate height has increased production cost.
The purpose of this utility model is that to overcome original structure intuitive poor, is difficult for observing, and the shortcoming of inconvenient operation, and simplified structure, the convenient manufacturing reduces cost, and makes alarm clock more inexpensive.
Structure of the present utility model as shown in drawings, in the accompanying drawings alarm-setting hand (1), clock dial (2), axle sleeve (3), alarm-setting axis (4), wheel (5), alarm spring (6), packing ring (7), alarm-setting axis spring (8), hexagonal nut (9) make a noise.Being improved to of alarm-setting mechanism, the front end of alarm-setting axis (4) stretches out clock dial (2) in addition, the alarm-setting axis front end is equipped with alarm-setting hand (1), be printed on to make a noise on the clock dial surface of the position of rotation of alarm-setting hand (1) and ring scale constantly, alarm-setting hand rotates with alarm-setting axis, the moment of alarm-setting hand indication promptly is that the noisy of alarm clock rings constantly, this structure is made a noise with the alarm-setting hand indication and is rung constantly, replacement is to the effect of the letter disk that makes a noise, cancelled the letter disk part in addition that makes a noise, other part axle sleeve (3), wheel (5) makes a noise, alarm spring (6), packing ring (7), alarm-setting axis spring (8), hexagonal nut structures such as (9) and effect are constant.
Advantage of the present utility model, because alarm-setting hand is in the clock dial of alarm clock outside, the position is very obvious and clear, it is convenient to observe, and has overcome the shortcoming that must observe by little garden arc window.The production of alarm-setting hand and the production of the letter disk that makes a noise compared, the production of alarm-setting hand is simple and make things convenient for, and scrappage is low, has reduced production cost, and this structure is specially adapted to mechanical small alarm clock use.
Structure in the accompanying drawing is a kind of of embodiment, and the shape of its alarm-setting hand is simple aciculiform.
Claims (2)
1, a kind of alarm-setting axis, axle sleeve, noisy wheel, alarm spring of comprising, the alarm clock alarm-setting mechanism of alarm-setting hand outside clock dial of parts such as alarm-setting axis spring, the front end that it is characterized in that alarm-setting axis (4) stretches out outside the clock dial (2) of alarm clock, the front end of alarm-setting axis (4) is fixed with alarm-setting hand (1), and being printed on the surface of the clock dial (2) of alarm-setting hand (1) position of rotation makes a noise rings scale constantly.
2, by the alarm clock alarm-setting mechanism of the described alarm-setting hand of claim 1 outside clock dial, the shape that it is characterized in that alarm-setting hand (1) is simple needle-like.
