CN2262255Y - Clock controlled automatic timer - Google Patents

Abstract

The utility model relates to a clock controlled automatic timer, composed of a miniature quartz electronic clock, a relay, a shift switch, a button switch, and a dry battery. A purpose-made metal electrical contact is arranged on a timing gear unit in the clock. The contact can be automatically closed and separated under the control of the clock. Thus, a control circuit can be switched on and cut off. Thereby, electric appliance equipment on a main circuit can be started through the relay. Meanwhile, the timer can also be used as a common clock.

Description

The clock autotimer

The utility model relates to a kind of simple and easy autotimer.It is formed by common quartz analog clock, midget relay, pushbutton switch, toggle switch and the dry cell combination of the transformation of the way.Can be particularly useful for controlling electrical equipment such as family expenses electric cooker, street lamp in the automatic control apparatus equipment action of any time of twenty four hours, can work as clock simultaneously and use.

Common timing device more complicated.As mechanical Mainspring type, elastic bag formula, illumination induction type, rechargeable, crystal instrumented, micro computer formula etc., preceding several shortcomings are can only be in one limited period regularly, and crystal instrumented and micro computer formula, though can 24 little in regularly, but its structure more complicated, cost is higher, can only be used for specific occasions, is difficult to be adopted by average family.

The utility model is intended to use for the ordinarily resident provides a kind of clock of can working as, again can be in twenty four hours any time control the simple and easy timer of relevant electrical equipment.

The purpose of this utility model is achieved in that to have in the small-sized quartz analog clock of locking device, the number of teeth transmission of the final stage gear of locking in original 12 hours is doubled, promptly drive the gear of one 64 tooth again, it can be moved in any time of twenty four hours by 32 original teeth.Mix two special spring contacts in addition, form a pair of contact that can regularly connect.With this contact and a midget relay, toggle switch, pushbutton switch are formed a control loop by lead, and when the timing contacting, the actuating of relay just can drive the electrical work of major loop; Crystal clock is contained in the refining box attractive in appearance, can work as clock simultaneously and use, and has so just realized the purpose of this utility model.

Below in conjunction with accompanying drawing the utility model is specified.

Fig. 1 is the outside drawing of an embodiment.

Fig. 2 is an electrical schematic diagram of the present utility model.

Fig. 3 is the regularly front elevation of structure of contact terminal of present embodiment.

Fig. 4 is the regularly cut-open view (part) of structure of contact terminal of present embodiment.

In Fig. 1, in the special box (21), fixing a small-sized quartz analog clock (16) through the transformation of the way, clock face has aperture (27), and the power supply of crystal clock and control loop is with No. five dry cells, be contained in the superjacent air space (20) of clock, following side space is placed pilot lamp (22), toggle switch (17), stop button (18) and a midget relay, there is a jack base (19) side of box, is used to connect the electric equipment that needs timing to start.

In Fig. 3 and Fig. 4, the timing gear that increases newly (11) is tended to act by the final stage gear (12) with 32 numbers of teeth, and timing gear (11) is changed system into 64 teeth, and modulus is constant, and scope therefore regularly is by becoming twenty four hours in original 12 hours.24 lattice scales are carved with on gear (11) surface, scale is over against the aperture (27) of clock face, the side of timing gear uniform three little slotted holes (13), on it is coaxial, adorning a roller (15), the roller edge axially uniform three little wedge teeth (10), the distribution garden radius of three little slotted holes is identical on wedge tooth distribution garden radius and the timing gear, therefore, when timing gear (11) forwards the position of a setting under the tending to act of gear (12), three wedge teeth (10) can slip in three little slotted holes (13) synchronously, simultaneously, under the effect of spring (8), a little displacement axially can take place in roller (15).A thin constantan sheet (9) is housed on the roller (15), is welding silver contact (2) on the copper sheet, when roller generation axial displacement, can be with copper sheet (9) to move together, the contact (1) on contact (2) another copper sheet (14) interior with being fixed on box is matched.Two copper sheets are connected in the control loop with lead, just play the effect of time switch.When contact (1) and (2) coincide, control loop was switched on, and makes the actuating of relay; The major loop that joins with relay and then is switched on, and consumer is just started working at preset time, has realized the effect that regularly starts.

When timing gear (11) is rotated further under the tending to act of gear (12), aperture will move along the inclined-plane of little wedge, and displacement in the other direction will take place roller gradually, and contact (1) is separated with (2), so just moves for timing next time and gets ready.

Fig. 2 is an electrical schematic diagram of the present utility model.The power supply of crystal clock and control loop provides owing to battery.Contact (1), (2) as preceding crystal clock (16) timing controlled of stating after the transformation of the way, contact (3) (4) and (5) (6) are controlled by toggle switch (17) respectively.If closed (3), (4) come into effect clock, closed (5), (6) are implemented manual, if press ammonium button (18) then can cut off control loop at any time, relay discharges, and major loop also is cut off, and consumer quits work.In Fig. 2, (23) and (24) contact is connected in the control loop on the relay, and (25) and (26) contact is connected in the major loop, and connects with socket (19), can join with the electric equipment switch/inlet of needs control at any time.Because crystal clock is connected in parallel in the control power circuit, and is installed in the box handsome in appearance, so no matter whether it is connected with electrical appliance, still can be used as the clock effect.Locking knob on the crystal clock is exactly that the utility model is as knob regularly.

The number of teeth of timing gear (11) can not change yet, and the moment of selecting like this to control can only be in 12 hours scope, and this form belongs to another kind of embodiment of the present utility model.
