Can laterally offer two jacks on the sidewall of described cylinder bottom on same horizontal plane, an end of described two sheet metals passes from two jacks respectively, and when described Metal Ball touched two metal sheets simultaneously, its minimum point was lower than cylindrical bottom end face.
Described switch housing can be annular, and its bottom can be provided with the circular bottom plate of a center drilling, and described cylindrical bottom passes downwards from the centre bore of base plate, and described two metal sheets is close on the bottom surface of base plate.
Described functional circuit plate can be fixed in cylindrical top.
Described power supply can be a battery pack that is composed in series by three batteries, and they all are clamped and fixed between base plate and the functional circuit plate.
Can also offer two through holes on the described base plate, the other end of described two metal sheets is upward through base plate from two through holes respectively, and is adjacent on the positive pole and negative pole that is fixed on two batteries.
In the inner chamber of described Metal Ball fixture spring can also be installed.
Because Metal Ball and sheet metal constitute a touch switch, Metal Ball drops on the sheet metal under the effect of gravity, thereby connects current supply circuit, and power supply makes the functional circuit plate enter operating state to the power supply of functional circuit plate.The function of described functional circuit plate can be set at multiple shape as required.Therefore the utlity model has simple in structure, characteristics such as switch is sensitive, functional strong, applied widely and energy savings.
Description of drawings
Accompanying drawing 1 is the cutaway view of the utility model gravity switch;
Structural profile view when accompanying drawing 2 is installed at the bottom of the glass for the utility model gravity switch.
Embodiment
Below in conjunction with Figure of description and specific embodiment the utility model gravity switch is described in further detail.
With reference to the accompanying drawings 1, the utility model gravity switch comprises switch housing 4 and is arranged at functional circuit plate 1 in the switch housing 4, Metal Ball 7, Metal Ball fixture, two sheet metals 8 and power supply and constitutes.
Described Metal Ball fixture is a vertically disposed cylinder 3, its bottom end opening.Described Metal Ball 7 places in the cavity of cylinder 3.Described cavity is cylindrical, and its central shaft overlaps with the central shaft of cylinder 3, and its internal diameter is identical with the external diameter of Metal Ball 7, Metal Ball 7 can only be moved up and down along cavity inner wall.
Described shell 4 is annular, and its bottom is provided with the circular bottom plate 5 of a center drilling, and described cylinder 3 is vertically set on the base plate 5, and its bottom passes downwards from the centre bore of base plate 5, and described two metal sheets 8 is close on the bottom surface of base plate 5.
Laterally offer two jacks on the sidewall of described cylinder 3 bottoms on same horizontal plane, an end of described two sheet metals 8 inserts and reaches the cavity of cylinder 3 from two jacks respectively, makes Metal Ball 7 can touch two metal sheets 8 simultaneously.And stretching into of described sheet metal 8 keeps enough spacings between the two ends in the cavity, and when touching two metal sheets 8 simultaneously with the described Metal Ball of box lunch, its minimum point can be lower than the bottom end face of cylinder 3.Go back from top to down on the described base plate 5 and offer two through holes, the other end of described two sheet metals 8 is respectively from two through holes upwards on the end face through base plate 5.
Described functional circuit plate 1 is fixed in the top of cylinder 3.
Described power supply is a battery pack that is composed in series by three batteries 9, is fixedly clamped between base plate 5 and functional circuit plate 1.The other end of described two metal sheets 8 is through being adjacent to respectively after on the end face of base plate 5 on the positive pole and negative pole that is fixed to two batteries 9 wherein.Described power supply is connected with the functional circuit plate, like this, battery pack, sheet metal 8, Metal Ball 7 and functional circuit plate 1 just have been composed in series a current supply circuit, and Metal Ball 7 and sheet metal 8 are the power switch of this current supply circuit, when Metal Ball 7 gravitates touch two metal sheets 8 simultaneously, circuit turn-on, battery pack begins to 1 power supply of functional circuit plate, 1 work of functional circuit plate, when Metal Ball 7 is left sheet metal 8 by other object jack-up, circuit disconnects, and functional circuit plate 1 quits work.
Structure cutaway view when accompanying drawing 2 is installed to the glass bottom for the utility model gravity switch.From scheming as seen, because when Metal Ball 8 touches sheet metal 7, its minimum point is lower than the bottom end face of cylinder 3, the glass that therefore the utility model gravity switch generally ought be housed is placed on the desktop, Metal Ball 8 contacts with desktop, Metal Ball 8 " is lifted ", and sheet metal 7 does not contact mutually with Metal Ball 8; When picking up cup, Metal Ball 8 has lost the support of desktop, because of itself action of gravity drops on two sheet metals 7.Because two sheet metals 7 connect the both positive and negative polarity of mains switch respectively, have so just connected circuit.Also be cup when picking up circuit connect, when cup puts down, circuitry cuts, thereby play the effect of mains switch.
Consider that toy or stationery are difficult to remain plumbness in use, but not during plumbness, Metal Ball 8 can not keep good contact with sheet metal 7, functional circuit can not be worked, therefore, when the utility model is used on toy or the stationery, install an external diameter additional less than cylinder 3 internal diameters, elastic force is slightly larger than the spring 6 of the weight of Metal Ball 8.Like this, when picking up toy or stationery, Metal Ball 8 " is ejected " by spring 6, make it to contact, thereby the conducting functional circuit also is that toy or stationery one leave the desktop function circuit and promptly starts working with two sheet metals, and do not mind whether keeping vertical, when putting back to desktop once more, quit work again.
The range of choice of functional circuit is very big on the functional circuit plate 1, can be flash effect, music effect, color effect, picture effect and warning function etc., as 3 light-emitting diodes 2 promptly being installed in the present embodiment to realize flash effect.
Because the function difference of functional circuit plate 1, range of application of the present utility model also can have all more options, such as: after showpiece or important item have been installed the utility model, will report to the police automatically in case be moved; After having adorned the utility model on toy or the stationery, when playing or use, just have music or colors changing hue, increase interest, or the like.
