Wireless remote control type electronic cipher alarming lock of the present utility model has such characteristics: can be used with traditional mechanical lock, also can independently make the coded lock of no lockhole.And, easy for installation, random, can be installed in the position that can't see outdoors, thereby prevent that effectively the thief from unblanking by key eye destruction door lock or with master key; The remote controller coded number can reach millions of groups, strong security, and the strick precaution performance is good, easy and simple to handle, and easy opening and easy locking also has music to do prompting and confirms; Because the installation site is random, can be installed in the place that any door, window, cabinet, case etc. need lock again, accomplish the many usefulness of a lock, one (or other need lock thing) many locks.

Below in conjunction with accompanying drawing, further specify embodiment of the present utility model, in the accompanying drawing:

Fig. 1 is the structured flowchart of circuit part of the present utility model;

Fig. 2 is the structural representation of mechanical part of the present utility model;

Fig. 3 is the electrical schematic diagram of the radiating portion among the utility model embodiment;

Fig. 4 is the electrical schematic diagram of the receiving unit among the utility model embodiment.

With reference to Fig. 1, when remote controller sends a predefined cipher instruction signal, this wireless signal receives, delivers to decoder after amplifying shaping, detection and decipher through antenna, if the password that receives is correctly then exported the corresponding instruction signal, if password bad no-output then.S2 among Fig. 1 is the microswitch that mechanical lock is unblanked the back drive, and S3, S4 are respectively coded lock and open, be locked into the microswitch that trigger the back, position.Output among this figure (OUTPUT) connects motor, and sensor input (SENSE INPUT) can connect the sensor of any model.

When shutting, as long as press the closing key of remote controller, after receiving system receives proper password, translate lock signal instruction, promote electronic switch, give in addition reversing the current of motor, dead bolt is released in the motor counter-rotating, and on door lock, motor stops operating simultaneously.Locking signal provides a high level signal to NAND gate.After dead bolt puts in place, drive microswitch S4 and close, music IC is triggered once, and loudspeaker are emitted musical sound, and expression locking work is finished.

When unblanking, when mechanical lock is opened, drive S2, the bistable trigger upset is exported a high level and is given NAND gate, provides standby electric power to electronic switch simultaneously.At this moment, as press the start key of remote controller, decoding output unlocking signal then, motor are just changeing dead bolt are being retracted, and the back that puts in place drives fine motion microswitch S3, triggers music IC again and emits music.Bistable circuit is under the triggering of unlocking signal, and upset is got back to and opened the beginning state, unblanks to finish.If after opening mechanical lock, do not press the start key on the remote controller, just coded lock does not receive correct unlocking signal, at this moment open the door by force again and just can trigger working sensor, export a high level signal, at this moment, three outputs of this NAND gate all are high level, its output produces a low level, thereby triggers the work of electronic switch warning circuit, and loudspeaker send alarm sound.Because the control section of electronic switch is connected with the output of bistable circuit, can not unblank because the start key of remote controller is pressed in maloperation.

Under the situation of microswitch S2 short circuit, the utility model can be made the cipher remote control electric lock of electromechanical integration separately.

The chargeable small battery of the utility model adapted is used civil power at ordinary times, uses standby electric power during power failure, as is unworthy of battery, also can be used with emergency light.

As shown in Figure 2, in this running part, the 1st, dead bolt (also claiming lock pin); 2,14 is alignment pin; 3,11 is spring; 7,8,9,15 is plain washer; The 4th, screw rod; The 5th, driver blade; 6, the 10th, fixed screw; 12 is connector; The 13rd, motor; The 16th, the lock pin sliding cavity.Owing to motor is that locking of fixing slided, like this, when motor just changeed (right-hand rotation), dead bolt slided to the right under the drive of screw rod; Otherwise, then slide left, thereby realize closing and opening function of lock.The key of this part is at 3,11 two springs and 7,9 two plain washers.Their effect is: the one, when screw rod 4 whole precessions or after all screwing out, guarantee that screw rod 4 can fully contact and then apply external force with driver blade 5 when moving for the second time; The 2nd, because plain washer the 7, the 9th, movably, after screw rod 44 rotations make plain washer and driver blade 5 contact, plain washer is with spring compression, the elastic force of spring again reaction on plain washer, producing certain frictional force between plain washer and driver blade becomes the external force that overcomes screw torque again, and the power of being used to that dead bolt is put in place after the motor outage plays certain effect that overcomes.Electronic switch by circuit part is just providing or reversing the current, drive dc motor 13 forward or reverse, this shaft of motor is joined by connector 12 and screw rod 4, screw rod 4 rotates with the rotation of motor, engagement by screw thread on the driver blade 4 and screw rod, the rotation of screw rod 4 becomes moving of driver blade, and then changes into lock pin 1 forward and back in lock pin sliding cavity 16, reaches out, locks two kinds of functions.At the lock state or open state, after putting in place, lock pin promptly stops power supply, consumed power not, and also after locking, lock pin can't reset by external force, thereby can effectively prevent to stir the generation that lock pin is opened lock.Driver blade 4 is its threaded antifriction metal (AFM) sheets in one side middle part.
