Description
Technical field
The utility model relates to a kind of door lock assembly, especially facilitates the energy-saving touch time delay LED illuminating lock for door of user's opening door lock in the situation that of insufficient light.
Background technology
Now common door lock is mainly divided into two kinds on the market, a kind of is electronic induction lock, another kind is traditional by key operated lock, because electronic induction lock is expensive, design is complicated, is not suitable for promoting the use of in general residential quarter, and for traditional door lock, when night or insufficient light, people are difficult to find keyhole, unblank to enter bring very large inconvenience to people.
Utility model content
The problem that is not easy to open the door when the insufficient light in order to solve existing door lock, the utility model provides a kind of energy-saving touch time delay LED illuminating lock for door, this illuminating lock for door can, by touch panel opening door lock LED lamp around, facilitate user's opening door lock in the situation that of insufficient light; In addition, LED lantern festival is automatically closed after time delay a period of time, has saved electric energy, and this door latch structure is easy, cheap, brings very large facility to people's life, is adapted at large-scale promotion on market.
The utility model solves the technical scheme that its technical problem adopts: this energy-saving touch time delay LED illuminating lock for door comprises lockhole, Door lock casing, LED lamp, control circuit board and sheet metal; The surrounding of described Door lock casing is uniformly distributed and is provided with illuminating LED lamp, and the middle part of Door lock casing has the lockhole of inserting key, lockhole be provided with control circuit board and sheet metal below, sheet metal and LED lamp are all serially connected in the circuit on control circuit board by wire.
On described control circuit board, the base stage of triode VT1 is connected with sheet metal by resistance R 6, the colelctor electrode of triode VT1 is connected with the dc source of+12V by resistance R 1, the emitter stage of triode VT1 is connected with one end of resistance R 7 and the base stage of triode VT2 respectively, the grounded emitter of the other end of resistance R 7 and triode VT2, the colelctor electrode of triode VT2 is by the dc source of resistance R 2 connection+12V; One end of resistance R 3 is connecting the colelctor electrode of triode VT2, the other end is connecting the base stage of triode VT3, and the colelctor electrode of triode VT3 is by resistance R 4 ground connection, after resistance R 5 is connected with LED lamp, in parallel with resistance R 4 again, the dc source of the emitter stage connection+12V of triode VT3; Triode VT1 and triode VT2 form the two-stage amplifying circuit of dc-couple, and triode VT3 forms on-off circuit.
When nobody touches sheet metal, sheet metal is unsettled, and the emitter junction of triode VT1 is anti-inclined to one side, and collector junction is anti-inclined to one side, and now VT1 is in cut-off state; The emitter junction of triode VT2 is anti-inclined to one side, and collector junction is anti-inclined to one side, and VT2 is in cut-off state; Now, the base stage of triode VT3 is without opening signal input, and triode VT3 is also in cut-off state, thereby do not have electric current to flow through LED lamp, and LED lamp does not work.When people touch sheet metal with hand, body current flows into the base stage of triode VT1 through R6, the rapid conducting of triode VT1, and the electric current that flows through itself is amplified to rear drive triode VT2 saturation conduction, make the collector potential of triode VT2 in low level, and make also conducting thereupon of triode VT3, LED lamp have electric current to flow through and luminous, in VT2 moment saturation conduction, collector current is to extremely approach+12V of capacitor C quick charge, but after immediate current disappears, triode VT1 and triode VT2 cut-off, because capacitor C forms discharge loop with emitter junction and the resistance R 2 of resistance R 3 and triode VT3 respectively, and the time constant of this discharge loop is larger, make the charge discharge of capacitor C storage slower, triode VT3 still keeps conducting state within a period of time, LED lamp can continue luminous a period of time, until the collector current of VT3 reduces to, to be not enough to driving LED lamp luminous, thereby realized the time-delay closing function of LED lamp, people in just can key being inserted to lockhole in LED lamp light yellow open door.
The beneficial effects of the utility model are that this illuminating lock for door can, by touch panel opening door lock LED lamp around, facilitate user's opening door lock in the situation that of insufficient light; In addition, LED lantern festival is automatically closed after time delay a period of time, has saved electric energy, and this door latch structure is easy, cheap, brings very large facility to people's life, is adapted at large-scale promotion on market.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural principle schematic diagram of the present utility model.
Fig. 2 is circuit catenation principle schematic diagram of the present utility model.
In figure, 1. lockhole, 2. Door lock casing, 3.LED lamp, 4. control circuit board, 5. sheet metal.
The specific embodiment
In the drawings, this energy-saving touch time delay LED illuminating lock for door comprises lockhole 1, Door lock casing 2, LED lamp 3, control circuit board 4 and sheet metal 5; The surrounding of described Door lock casing 2 is uniformly distributed and is provided with illuminating LED lamp 3, the middle part of Door lock casing 2 has the lockhole 1 of inserting key, below lockhole 1, be provided with control circuit board 4 and sheet metal 5, sheet metal 5 is all serially connected in the circuit on control circuit board 4 by wire with LED lamp 3.
On described control circuit board 4, the base stage of triode VT1 is connected with sheet metal 5 by resistance R 6, the colelctor electrode of triode VT1 is connected with the dc source of+12V by resistance R 1, the emitter stage of triode VT1 is connected with one end of resistance R 7 and the base stage of triode VT2 respectively, the grounded emitter of the other end of resistance R 7 and triode VT2, the colelctor electrode of triode VT2 is by the dc source of resistance R 2 connection+12V; One end of resistance R 3 is connecting the colelctor electrode of triode VT2, the other end is connecting the base stage of triode VT3, and the colelctor electrode of triode VT3 is by resistance R 4 ground connection, after resistance R 5 is connected with LED lamp 3, in parallel with resistance R 4 again, the dc source of the emitter stage connection+12V of triode VT3; Triode VT1 and triode VT2 form the two-stage amplifying circuit of dc-couple, and triode VT3 forms on-off circuit.
