Abstract

The utility model discloses an alarm switch device for a quartz clock. The alarm switch comprises an alarm plate, an electric-conductive reed, a circuit board and an alarm stop switch. One end of the alarm plate (1) is a locating end, while the other end is equipped with a notch (12) with a groove. The notch is vertical to the alarm plate. A groove edge of the notch extends forwards to form a single fork piece, the end of which is an inward slant surface. An arch end of the alarm reed (2) is equipped in the groove of the notch of the alarm plate and is arrayed opposite to the alarm plate. As the alarm start function and the alarm stop function are designed on the same cross-section in the novel clock alarm switch, consistency of the start stroke and the stop stroke are guaranteed. As the function of electric conductivity and the function of alarm are integrated, little room is taken up in the alarm chip and thus the circuit board needed is provided with small dimension, which saves the material and reduce the cost.

Description

Alarm clock plays noisy switchgear

Affiliated technical field

The utility model belongs to the crystal clock field, especially relates to the noisy switchgear that rises of crystal clock.

Background technology

In existing technology, conduction spring, the alarm spring of the noisy core of crystal clock are two independently elements, are used and could move, operation is loaded down with trivial details during assembling, and the volume of two elements is big, requires the volume of the wiring board corresponding with it big, therefore, in making a noise core, crystal clock takes up room greatly.Playing, ending the configuration aspects of making a noise, adopt metal material or plastics no matter be, there is the unfavorable defective of consistance in the capital, such as: the design of two V shape metal alarm spring sheets is to contact wiring board simultaneously by two forks to come the conducting circuit, thereby reaches the function of regularly making a noise, its reliability is subjected to the conforming restriction of metal material, cause same punching press sizing die, also be difficult to guarantee two forks on same plane, thereby it is bad to cause product to occur on a noisy function.

Summary of the invention

In order to overcome the above deficiency of prior art, the utility model provides a kind of volume little and functional reliability good, conduction noisyly plays noisy switchgear for the alarm clock of one with rising.

The technical solution of the utility model is: alarm clock works the switchgear that makes a noise and comprises noisy plate, conduction alarm spring sheet, circuit board and end the switch that makes a noise, plate one end that makes a noise is a positioning end, the other end of noisy plate has the notch that have groove perpendicular with it, the groove of this notch is along extending a single tine sheet forward, and the termination of this single tine sheet is interior scarf; One arced terminus of making a noise reed places in the groove of the board slot mouth that makes a noise and with described noisy plate and becomes relative arrangement.

Because the utility model alarm clock works rising, ending and make a noise the function design on same cross section of the switchgear that makes a noise, a thereby consistance of guaranteed, ending the stroke that makes a noise, make it reliable in function, and will to conduct electricity with playing a noisy function collection be one, simple in structure, reliable, minimizing assembly process, space shared in the core that makes a noise is little, and required circuit board volume is little, save material, reduce cost.

Description of drawings

Fig. 1 plays the main TV structure synoptic diagram of noisy switchgear for the utility model alarm clock.

Fig. 2 plays the plan structure synoptic diagram of noisy switchgear for alarm clock.

Among the figure: the 1-plate that makes a noise, 11-single tine sheet, 12-notch, the 2-reed that makes a noise, the 3-circuit board, 4-ends the switch that makes a noise.

Below in conjunction with drawings and embodiments the utility model is described in further detail.

Embodiment

As shown in Figure 1, the utility model alarm clock works the switchgear that makes a noise and comprises noisy plate (1), conduction alarm spring sheet (2), circuit board (3) and end the switch (4) that makes a noise, plate (1) one end that makes a noise is a positioning end, the other end of noisy plate (1) has the notch that have groove (12) perpendicular with it, the groove of this notch is along extending a single tine sheet (11) forward, and the termination of this single tine sheet is interior scarf; One arced terminus of making a noise reed (2) places in the groove of the board slot mouth (12) that makes a noise and with described noisy plate (1) and becomes relative arrangement.

During installation, the reed (2) that makes a noise is positioned at the top of circuit board (3), and the electrode slice disjunctor in this noisy reed (2) and the movement also becomes vertical relation, and make a noise reed and electrode slice are fixed stiff end in the circuit board, same direction arrangement.The positioning end of noisy plate (1) is installed on the base of hour wheel and third wheel centre, is short and small state.In order rise to make a noise and to end when making a noise, the stress point of the plate (1) that makes a noise requires the height of notch (12) groove just in time to satisfy the stroke requirement of the reed (2) that makes a noise on same cross section, and promptly the drop of groove height and noisy reed arced terminus matches.

During work, referring to Fig. 1, Fig. 2, do not arrive rising the noisy time of setting, the noisy cover salient point of the rising of wheel top of promptly making a noise does not fall in the wheel pit that makes a noise, the noisy plate (1) that being contained in makes a noise overlaps the top is the noisy reed (2) of jack-up just in time, noisy reed (2) is not contacted with circuit board (3), when movement runs to time of rise making a noise of setting, work the cover salient point moment of making a noise to fall in the pit of the wheel that makes a noise, under the pressure of reed (2) that makes a noise, the plate (1) that makes a noise also descends along with working the cover that makes a noise, and the reed (2) that makes a noise this moment contacts with circuit board (3), begins to ring and makes a noise.

When end making a noise, stir and end the switch (4) that makes a noise, act on the interior scarf place of single tine sheet (11) by ending the switch slope of making a noise, the plate (1) that will make a noise promotes, and noisy reed (2) is promoted to breaking circuit plate (3) always, having reached that ending makes a noise acts on.

Claims

1, a kind of alarm clock plays noisy switchgear, comprise noisy plate (1), conduction alarm spring sheet (2), circuit board (3) and end the switch (4) that makes a noise, plate (1) one end that makes a noise is a positioning end, it is characterized in that: the other end of the plate (1) that makes a noise has the notch that have groove (12) perpendicular with it, the groove of this notch is along extending a single tine sheet (11) forward, and the termination of this single tine sheet is interior scarf; One arced terminus of making a noise reed (2) places in the groove of the board slot mouth (12) that makes a noise and with described noisy plate (1) and becomes relative arrangement.
