Abstract
The utility model relates to a clock which can timing and controlling the on-off of a power supply. The alarm setting pressure spring and the dial of a clock are additionally provided with a contact point in order to form the switch of a mechanical timer. A timing switch, the power supply, a low-voltage DC transformer, a double-stage switch and the electromagnetic coil of a relay are connected in series to form a control circuit. The switch of a relay contact, an electric appliance and the power supply are connected in series to form a working circuit which is used for control on-off of the electric appliance in definite time. The clock of the utility model can time and continuously control the on-off of the power supply. The utility model has the advantages of simple structure, time saving and electricity saving; the utility model can be used as an ordinary clock when the power supply and the electric appliance are not connected.
Description
But the utility model relates to the clock of a kind of timing controlled power supply open and close.
But the clock of existing timing controlled power supply open and close, the complex structure that has, the control time that has is not long.CN2133010Y discloses a kind of clock of charged device timer, and its utilizes with the switch of locking stage clip mechanical connection and one and is serially connected in the third gear switch that needs between time-controlled electric switch and the power supply, and electrical equipment is carried out regularly energising or outage is controlled.The shortcoming of this clock is that the control time is not long, and it only can carry out control by increasing the opening of locking time disk in 6-9 hour.
The utility model purpose is to provide a kind of above-mentioned shortcoming that overcomes, and is simple in structure, safe and convenient to use, the power saving that saves time, and the clock of energy Sustainable Control power supply open and close.
The utility model is realized by following measure: the locking stage clip of common alarm clock is oppositely installed for 180 °, and set up contact in its end and on relevant position, the clock dial back side, set up contact, form the mechanical timer gauge tap, this multi-functional time-controlling clock, include the clock body, the mechanical timer gauge tap, the low-voltage direct transformer, double gear switch, also comprise duplex relay in addition, this duplex relay by two around forming to identical solenoid and relay contact switch, relay contact switch is the travel(l)ing rest formula, by fixing support, fixing contact chip and one be clamped in support and the steel ball that holds by fixing spring between mobilizable lever pressing plate form, its low-voltage direct transformer is connected between mechanical timer switch and the double gear switch, two gears of double gear switch are composed in series control circuit with two solenoids of duplex relay respectively, relay contact switch is connected between electrical appliance and the power supply, forms operating circuit.Wherein lever pressing plate 12 two ends are provided with insulator.
Accompanying drawing 1 is an electrical equipment control schematic diagram of the present utility model.
Accompanying drawing 2 is the structural representation of mechanically controlled switch.
Accompanying drawing 3 is the structural representation of duplex relay.
K wherein
1Be mechanically controlled switch, install and the contact of setting up in its end 4 and the contact of setting up on clock dial 5 back sides and contact 4 relevant positions 6 are formed for reverse 180 ° by the locking stage clip 3 of alarm clock, contact 4, contact 6 and the insulation of clock body, 1 is the low-voltage direct transformer, 2 is duplex relay, by two around to identical solenoid J
A, J
BWith travel(l)ing rest formula contact switch K
3Form travel(l)ing rest formula contact switch K
3By fixed support 8, fixed contact piece 9 and support 8 are formed with mobilizable lever pressing plate 12 of steel ball 10 and spring 11 clampings, and lever pressing plate two ends also are provided with insulator, manually the pilot relay K switch
3Break-make, K
2Be double gear switch, its A, B two gears respectively with relay in two solenoid J
A, J
BLink to each other.
Now in conjunction with the accompanying drawings the utility model operating position is described in detail.
The utility model is if need control apparatus regularly open-minded, at first with double gear switch K
2Place the A position, and on clock, set up the moment that to open, with relay contact switch K
3Manually disconnect, the plug with electrical equipment inserts the receptacle of being located on the clock then, with the attaching plug insertion supply socket of clock.When clock arrived predetermined instant, the locking stage clip became release conditions from compressive state, produced pressing action, made mechanically controlled switch K1 closure, and control circuit is connected, and low voltage direct current is by solenoid J
AThe time produce electromagnetic force, under the electromagnetic force effect, lever pressing plate 12 is to solenoid J
ABe close to, thereby contact with fixed contact piece 9, connect operating circuit, electrical equipment carries out timing working.After clock was passed by predetermined instant, the locking stage clip was returned to compressive state again, mechanically controlled switch K
1Disconnect the solenoid J in the control circuit
AOutage, magnetic force disappears, and lever pressing plate 12 is because of there being the clamping action of fulcrum 8 steel balls 10 and spring 11, so lever pressing plate 12 still contacts with contact chip 9, operating circuit is conducting still.Solenoid only in the short time energising, guarantees the solenoid trouble free service.
If need control apparatus regularly to turn-off, then need with double gear switch K
2Place the B position, and with relay contact switch K
3Manually connect, all the other operations are same as described above.When arriving predetermined instant, solenoid J
BProduce electromagnetic force, under the electromagnetic force effect, the lever pressing plate is close to solenoid, relay switch K
3Disconnect, the operating circuit power supply also disconnects thereupon, and electrical appliance is the timing interruption of work therefore.
Characteristics of the present utility model are: can not make ordinary clock when not connecing power supply and electrical equipment, and in the time will carrying out the timing open and close to electrical equipment, the energy Sustainable Control, and safe and reliable, easy to use, power saving saves time.
