Description

The double; two timer circuit of a kind of electronic clock

Technical field

This utility model relates to a kind of timer circuit, specifically the double; two timer circuit of a kind of electronic clock.

Background technology

Chess timer clock is a kind of for chess (go, chess, Chinese chess etc.) mass tournament or amateur play chess the time set of middle control both sides chess player respective time used, board game is desirable that restriction both sides chess player's play chess time, it is thus desirable to use timer, existing chess timer comes with some shortcomings, such as complicated operation, other people are needed to help to control, or each self clock of both sides, error when therefore operating is bigger, when dramatic match, it is susceptible to because of the other side chess player's fixture and has walked the situation that step number preferably affects self and plays, disperse the attention of chess player, affect the performance of chess player, therefore need to be improved.

Utility model content

The purpose of this utility model is in that to provide a kind of simple in construction, electronic clock easy to use double; two timer circuit, with the problem solving to propose in above-mentioned background technology.

For achieving the above object, this utility model provides following technical scheme:

nullThe double; two timer circuit of a kind of electronic clock，Including electronic clock A、Key switch S1、Diode D2 and unidirectional thyristor Q1，One end of described switch S1 connects electronic clock A、Electronic clock B、Resistance R1、Switch K and key switch S3，The other end of key switch S1 connects the control pole of unidirectional thyristor Q1，The other end of electronic clock A connects negative electrode and the key switch S2 of diode D2，The other end of key switch S2 connects the anode of unidirectional thyristor Q1，The negative electrode of unidirectional thyristor Q1 connects the negative pole of accumulator E and the negative electrode of unidirectional thyristor Q2，The anode of unidirectional thyristor Q2 connects key switch S4，The other end of key switch S4 connects the negative electrode of diode D1 and the other end of electronic clock B，The anode of diode D1 connects the other end of resistance R1 and the anode of diode D2.

As preferred version of the present utility model: described key switch S1 and key switch S2 is gang switch, key switch S3 and key switch S4 is gang switch.

Compared with prior art, the beneficial effects of the utility model are: the double; two timer circuit simple in construction of this utility model electronic clock, components and parts are few, two electronic clocks and two groups of gang switches are adopted to realize double; two timing and control, and operate very easy, simultaneously respectively also with lamplight pointing, therefore there is the advantage that environmental protection, cost are low and easy to use.

Accompanying drawing explanation

Fig. 1 is the circuit diagram of the double; two timer circuit of electronic clock.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.

nullRefer to Fig. 1，The double; two timer circuit of a kind of electronic clock，Including electronic clock A、Key switch S1、Diode D2 and unidirectional thyristor Q1，One end of described switch S1 connects electronic clock A、Electronic clock B、Resistance R1、Switch K and key switch S3，The other end of key switch S1 connects the control pole of unidirectional thyristor Q1，The other end of electronic clock A connects negative electrode and the key switch S2 of diode D2，The other end of key switch S2 connects the anode of unidirectional thyristor Q1，The negative electrode of unidirectional thyristor Q1 connects the negative pole of accumulator E and the negative electrode of unidirectional thyristor Q2，The anode of unidirectional thyristor Q2 connects key switch S4，The other end of key switch S4 connects the negative electrode of diode D1 and the other end of electronic clock B，The anode of diode D1 connects the other end of resistance R1 and the anode of diode D2.

Key switch S1 and key switch S2 is gang switch, and key switch S3 and key switch S4 is gang switch.

Operation principle of the present utility model is: during use, first Guan Bi on and off switch K, if first moving in left, the button S3 of oneself side then should be first clicked by right, at this moment unidirectional thyristor Q1 is turned on by the voltage triggered through switch S3, then electronic clock A obtains the electric timing that carries out through normally closed switch S2 with unidirectional thyristor Q1 loop, and light emitting diode D2 makes corresponding instruction simultaneously.After moving in left, then click the button S1 from side conveniently, disconnect with the normally closed switch S2 moment immediately of S1 linkage, and make unidirectional thyristor Q1 transfer cut-off to because of cutout, then electronic clock A timing releases.Meanwhile, the synchronization action of S1 makes again its upper contact close so that unidirectional thyristor Q2 obtains triggering and conducting；Circuit conversion is that right chronometer must establish beginning timing by cable, and its timing mode is identical with above-mentioned steps, and then realizes the control of double; two timing accurately.
