Description

Door lock energy saving device

The present invention relates to a kind of door lock energy saving device, especially for the door lock energy saving device of pin tumbler lock.

Door lock in the past mostly has only the effect of locking door, and does not give indoor whole or partly load outage when leaving automatically when the people locks a door, perhaps the function of powering up for some load simultaneously.Though some lock can be realized this function, being based upon has on the basis of very big change existing lock structure, and relatively poor at the discriminating power of the outdoor This move of locking a door to the people, and easy and other action of closing the door is obscured, and makes troubles for production and use.

The objective of the invention is to propose a kind of door lock energy saving device, this device can be discerned the people exactly at the outdoor This move of locking a door, and This move reacted:, power up perhaps for simultaneously some electrical equipment, and after door is opened, restore electricity immediately indoor all or part of load outage.This device need not changed former lock construction or only do very little change just applicable to the pin tumbler lock of any kind of.

The objective of the invention is to realize by following technological means.

A tapered end switch is housed on tapered end, and this switch can detect whether key inserts or whether lock core rotates; Being contained in a door switch that door goes up or lock is used for detecting gate and is in and closes or opening.The signal of these two switches directly transmits or is transferred to logic circuit by the photo-coupler of being made up of light-emitting component and light-sensitive element, logic circuit identification door is closed and is had key insertion or lock core to rotate This move and is the action of locking a door, and export high level signal in this case, and keep this output always, be unlocked until door.This circuit can be thought by mistake unblanking and lock a door, but this does not influence the function of device, because this moment, circuit was exported locked to be high level, to have only after door is opened that it is low level output that circuit just overturns.The output of logic circuit is amplified the rear drive executive component to the load outage or power up through amplifying circuit.

Describe the present invention in detail below in conjunction with accompanying drawing.

Shown in Figure 1 is electric functional-block diagram of the present invention.

Among Fig. 1, power unit is converted to direct current with alternating current, power supply is provided for whole device, the input of logic circuit is controlled by the tapered end switch that is contained in the door switch on door or the lock body and be contained on the tapered end, the output of logic circuit is amplified the rear drive executive component through amplifying circuit and is given load 1 outage, powers up for simultaneously load 2.

The present invention also can adopt circuit structure shown in Figure 2.

Among Fig. 2, the switching signal of tapered end switch is to be transferred to logic circuit by the photo-coupler of being made up of light-emitting component and light-sensitive element, and energy transform device is used for providing power supply to light-emitting component, can be transformer or photocell.Door switch is contained on doorframe or the snap close, the structure of remainder and principle and shown in Figure 1 identical.

Further specify the present invention below in conjunction with embodiment.

Fig. 3 and shown in Figure 4 be two kinds of typical circuits of the present invention.

Among Fig. 3, normally closed switch K2 is the door switch that is contained on door or the lock body, and its working method is the closing of contact when door is opened, and the contact disconnects when door is closed; Normal open switch K1 is the tapered end switch that is contained on the tapered end, and its working method is the closing of contact when key insertion or lock core rotation, otherwise the contact disconnects.Logic circuit is made of two nor gate IC1, IC2 being connected into the latch form.During outdoor locking a door, at first door is closed as the people, and K2 disconnects, the input 1 of IC1 is a low level, and key inserts lock core and rotational lock core, K1 closure then, give IC2 a high level input,, do not open so need only door because IC1 and IC2 are connected into the latch pattern, be that K2 keeps off-state, IC2 will keep low level output, and transistor Q1 ends, and relay discharges, give the load that is connected on the relay normally open contact 1 outage, power up for simultaneously the load 2 that is connected on the relay normally open contact.After door is opened, give IC1 a high level input, the output switching activity of IC1 and IC2 and locking once more, IC2 is output as high level, transistor Q1 conducting, the relay power adhesive restores electricity for the load 1 that is connected on the relay normally open contact, gives the load that is connected on the relay normally open contact 2 outages simultaneously.Because this IC2 output is locked as high level, so short of action of locking a door with key, relay will be kept attracting state.

Among Fig. 4, the switching signal of tapered end K switch 1 is transferred to logic circuit by the photo-coupler of being made up of light emitting diode D5 and photosensitive tube Q2, door switch K2 is contained on doorframe or the snap close, its course of work is: when K1 is closed, the light emitting diode electrified light emitting, photosensitive tube is subjected to conducting behind the light, gives IC2 a high level pulse input.Light emitting diode is by transformer B power supply, and the magnetic core of transformer B is divided into two parts, and respectively in shackle sides and lock body side, its primary coil is in shackle sides, and secondary coil is in the lock body side.The structure of the remainder of circuit and operating principle and shown in Figure 3 identical.

The structure of aforementioned lights coupler and transformer B with as shown in Figure 5.

Among Fig. 5, (1) be the snap close panel, (2) are door switch, are switches with constant close contact, if magnetic switch or reed capsule, with the corresponding lock panel in its position (6) on magnet (7) is housed, (3) are the shackle sides magnetic cores of transformer B, (4) are primary coils, (5) be photosensitive tube or photosensitive clad pipe, (8) be lock body side magnetic core, (9) are secondary coils, and (10) are light emitting diodes." " shape magnetic core also can be adopted in the magnetic core of transformer B (3) and (8), and door switch (2) also can be a travel switch that constant close contact is arranged.

Among Fig. 6, be that the amplifying circuit of core is connected into disconnected delay switch form with Q1, can make the work of circuit more reliable like this, antijamming capability is stronger.Its course of work is: when the output of IC2 and door switch K2 is high level, and transistor Q1 conducting, the relay power adhesive restores electricity for the load 1 that is connected on the relay normally open contact, gives the load that is connected on the relay normally open contact 2 outages simultaneously.C1 charges by R3 simultaneously; When the defeated upset of IC1 and door switch is low level, C1 is by the grid leak resistance discharge of R3 and R4 and Q1, when the terminal voltage of C2 is lower than the cut-in voltage of Q1, Q1 ends, relay discharges, give the load that is connected on the relay normally open contact 1 outage, power up for simultaneously the load 2 that is connected on the relay normally open contact.

The tapered end switch can adopt Fig. 7 or structure shown in Figure 8.
