Description

Bell-controlled mains switch

The utility model clock power switch relates to the power switch technical field, is applicable to automatic switch, electric cooker, electric light, household electrical appliance such as televisor.

The power control switch of present household electrical appliance, generally by copper sheet, plastic casing constitutes pullswitch or double-break switch, this switch manual control, the time spent opening power, time spent powered-down not, this power switch exists simple in structure, the moment energized that can not be scheduled to according to people and cut off the electricity supply by the moment that people are scheduled to quits work household electrical appliance.

The purpose of this utility model provides a kind of clock power switch, uses this switch and is installed on the household electrical appliance, can reach the power supply of automatic open and close household electrical appliance, has the purpose of the range of application that enlarges mechanical alarm clock.

The design (Fig. 1) of the utility model clock power switch is by mechanical alarm clock (1), supply socket (2), connects lever bar (3), Timing power supply seat (4,6), and the gear that gives the correct time (5), idle wheel (7) are formed.Wherein alarm clock (1) is selected mechanical alarm clock of the prior art for use, and by the power clockwork spring, the time movement and the mechanism of giving the correct time form.The utility model is under the constant situation of the structure that keeps original mechanical alarm clock (1), utilize the gear that gives the correct time in the mechanical alarm clock (1), the timing regulating shaft, and noisy official seal clockwork spring is as Controlling Source, and then, connect lever bar (3), Timing power supply seat (4,6) supply socket (2), and idle wheel (7) and the gear that gives the correct time (5) be installed on the clock shell of alarm clock and on the core frame, and its concrete design is:

1, be installed on the left and right clock shell of alarm clock (1) by screw with two supply sockets (2), and with a wire connecting power " zero " line, power firestreak is connected to an end of Timing power supply seat (4) from an end of supply socket with lead, the other end connects an end of Timing power supply seat (6), is connected on the live wire of power socket (2) from the other end again then.Timing power supply seat (4) is made the strip stand with bakelite, in the middle of the stand mounting screw hole and power supply wiring hole is arranged, and two M are installed in the hole ₃The brass screw of * 8mm, power firestreak are connected on the screw, and Timing power supply seat (4) passes through M ₃The button-headed screw of * 10mm is connected on the left end of casing.Timing power supply seat (6) is made the square stand of two block lengths with bakelite, the power supply screw hole is arranged in the middle of the stand, make the insulating trip of 15 * 8mm with polytetrafluoroethylmaterial material simultaneously and make the conducting strip of 15 * 8mm with copper sheet, porose on insulating trip and the conducting strip, conducting strip is installed in a middle terminal that constitutes Timing power supply seat (6) of insulating trip and rectangle stand by screw, then with the terminal of same two Timing power supply seats (6), be connected by screw on the casing on mechanical alarm clock quarter-bell clockwork spring next door, two conducting strip overlap joints of Timing power supply seat (6) are touched, terminate at from one of Timing power supply seat (4) with lead on the conducting strip of a stand of Timing power supply seat (6), the conducting strip of another stand is connected on the live wire of supply socket (2).Connect lever bar (3) and make the lever bar with bakelite, be connected with the arc made from copper sheet by screw on one end of lever bar and be communicated with sheet, sharp hook (Fig. 2) is arranged on the other end of lever bar, and on the spring of the timing disc bar of alarm clock (1), be equipped with moving plate, Timing power supply seat (4) is not when having energized, the point hook hangs over on the moving plate, connect lever (3) is installed in core frame by screw nut center (Fig. 3), form the lever central pivot point, simultaneously between fulcrum and sharp hook, be drilled with an aperture, backguy is housed in the hole, and clock shell outside is drawn in backguy.Idle wheel (7) is 12 gear with the number of teeth in the existing alarm clock, be installed on the alarm clock movement frame with an axle of carrier pulley, the gear (5) that gives the correct time is 48 gear with the existing alarm clock number of teeth, be installed in equally on the core frame of alarm clock with an axle, the tooth of gear (8) carries out meshing transmission with the tooth of idle wheel (7) when use, and the tooth of idle wheel (7) carries out meshing transmission formation clock power switch with the tooth of the gear that gives the correct time (5) again.

2, the course of work of clock power switch is: the alternating current 220V attaching plug is inserted in the left end supply socket (2), rotate the gear shaft (5) that gives the correct time, with pulling backguy, after connection lever bar (3) wing is risen, point is hooked on on the moving plate, and the gear that gives the correct time (5) is fixed the moment of wanting energized in advance simultaneously, gear when walking (8) drives to the gear that gives the correct time (5) by idle wheel (7), when reaching predetermined instant, the sharp hook that connects on the lever bar comes off, connecting the lever bar falls, make the arc on the lever bar be communicated with two contact screws that sheet touches Timing power supply seat (4), even if the connection AC power makes the electric equipment work that inserts in another supply socket.The noisy official seal axle of rotation simultaneously tightens up the official seal clockwork spring that makes a noise, and the noisy official seal of predetermined instant, when official seal rings in case regularly make a noise, be the clock timing power cutoff time, the official seal clockwork spring that makes a noise is just stretched to expand and is opened contact Timing power supply seat (6), two conducting strips of overlap joint are flicked and deenergization, reach the regularly purpose of power cutoff.

The effect of the utility model clock power switch is compared with prior art, this power switch is that the power supply predetermined switch is installed on the existing machinery alarm clock, the technical feature that not only can keep the existing machinery alarm clock, reached with mechanical alarm clock simultaneously and controlled household electrical appliance, make household electrical appliance energized on schedule, the effect of power cutoff on schedule uses household electrical appliance to bring convenience to people again, can save more time and be engaged in working and learning.Also increase simultaneously the function of mechanical alarm clock, enlarged usable range.Have simple in structurely, cost is low, and advantage of wide range of application is a kind of mechanical alarm clock to be carried out organic the combination with power switch, the effect that brings convenience to the user.
