To unlock the door. Therefore, the user can open the door and enter the inside.

On the other hand, when the key is rotated in the opposite direction to the above, the locking lever 24 is reversed by the action of the key bundle 20 to operate the locking means in the reverse direction, the locking means push the lock 50 to lock the door Let's do it. In this state, the door cannot be opened.

As described above, the action of locking the door and releasing the lock can be obtained by rotating the inner lever 40 attached to the inner case 30.

However, in such a mechanical locking device, since the key insertion hole 22 and the key bundle 20 are expressed in a separate manner, the key lock hole is inserted into the key insertion hole 22 to operate the key bundle 20 to lock the door. It is easy to release the key bundle 20 from the door by releasing or deodorizing tool to unlock the door. Therefore, there is a problem that the mechanical locking device is capable of unlocking unauthorized criminals and there is a risk of theft.

The interlock lever 220 maintains a constant distance from the solenoid 230 by the first bush 242.

When the holder 300 is brought into close contact with the O-ring 288 in this state, the first ball 276 is positioned in the first inner circumferential groove 304 of the holder 300, and the first inner circumferential groove 304 is disposed in the first ball. The interlocking lever 220 is fixed to the cylinder 270 by pushing 276 into the eighth through hole 274 to be inserted into the first outer circumferential groove 224 of the interlocking lever 220.

Subsequently, when the plurality of second balls 312 are inserted into the twelfth through holes 310 formed in the holder 300, the second balls 312 are formed in the third outer circumferential groove 280 of the cylinder 270 and the holder 300. It is inserted between the second inner circumferential groove 306 of the () to secure the holder 300 to the cylinder 270. When the third ball 314 having a larger radius than the second ball 312 is press-fitted into the twelfth through hole 310, the second ball 312 is prevented from escaping into the twelfth through hole 310.

As described above, in the state in which the interlock lever 220 is coupled to the cylinder 270, the holder 300 presses the first ball 276 so that the first ball 276 opens the protrusion 222 of the interlock lever 220. The cylinder 270 is fixed, and the second ball 312 fixes the holder 300 to the cylinder 270. Therefore, since the third ball 314 is press-fitted into the twelfth through hole 310, the second ball 312 also does not come out of the twelfth through hole 310, and as a result, the interlocking lever 220 is connected to the cylinder. It becomes impossible to decompose from 270. In other words, the interlock lever 220 is not possible to disassemble after assembly.

Finally, the outer lever 210 is coupled to the interlock lever 220, and the third screw 214 is connected to the third screw hole 212 of the outer lever 210 and the seventh through hole 226 of the interlock lever 220. ), The outer lever 210 is fixed to the interlocking lever 220 and is in a state of being integrally rotated.

In this way, the opening and closing device 200 is assembled, one end of the key lever 260 is inserted into the first coupling groove 162 formed in the fastener 160 of the locking device 100, the mounting plate 290 is a door It is positioned inside the door 600 in a state of being attached to the outer surface of the 600. Then, the bolt fastening hole 289 formed in the bottom surface of the cylinder 270 by passing the plurality of second bolts 176 through the plurality of second bolt through holes 174 formed on the rear surface of the case 110 of the locking device 100. ) Therefore, the cylinder 270 is fixed at a predetermined distance from the case 110 of the locking device 100.

When the installation of the opening and closing device 200 is completed as described above, only the outer lever 210 is visible when viewed from the outside of the door 600.

On the other hand, the control device 400 for supplying power to the solenoid 230 through the wire 232 is installed in the interior space of the door 600. The buzzer 450 and the lamp 440 are installed to be exposed to the interior of the door 600, the shock sensor 430 is installed on the outer plate in the interior of the door 600.

This completes the assembly of the locking device 100, the opening and closing device 200 and the control device 400.

The secret code input device 500 is carried by the user.

Hereinafter will be described the operation of the door locking device assembled as described above.

When the door 600 is opened, the switch 530 of the secret code input device 500 is pressed to generate a frequency corresponding to the secret code input to the second memory 516 from the second C. 514 and the oscillator. The control unit 520 generates a specific frequency, and the modulator 518 is controlled to intermodulate the frequency generated by the oscillator 520 and the frequency of the secret code. The frequency modulated by the modulator 518 is amplified by the RF amplifier 522 to a predetermined level and radiated through the transmission antenna 524.

At this time, the control device 400 amplifies the RF signal received from the reception antenna 412 by the RF amplifier 522 and the complex code signal among the frequency signals amplified by the RF amplifier 522 by the demodulator 416. The first CPI 418 determines whether the detected composite code signal is the same as the secret code input to the first memory 420.

As a result of this determination, when the composite code signal and the secret code coincide, the first CUI 418 drives the driver 422 to apply power to the solenoid 230.

Accordingly, the drive shaft 234 of the solenoid 230 moves toward the connector 250, and the second coupling piece 244 is inserted into the second coupling groove 252 of the connector 250. At this time, the first coupling piece 238 slides in the sliding groove 228 of the interlocking lever 220 and does not leave the sliding groove 228.

At this time, even if the second coupling piece 244 is not inserted into the second coupling groove 252 at once, the second coupling piece 244 is continuously pushed toward the connector 250 as long as there is a driving force of the solenoid 230, If the second coupling piece 244 is rotated by rotating the outer lever 210 to match the '-' shape in any one of the '+' shapes of the second coupling groove 252, the second coupling piece 244 is The solenoid 230 is easily inserted into the second coupling groove 252 by the pushing force.

Such a state is the same as that of FIG. 10, and the outer lever 210, the interlocking lever 220, the drive shaft 234 of the solenoid 230, the connector 250, and the key lever 260 are connected to each other. Will be rotated.

Therefore, when the user rotates the outer lever 210 on the outside of the door 600, the key lever 260 is rotated to rotate the fastener 160 of the locking device 100.

The fastener 160 rotates the disc gear 140 and the disc gear 140 moves the latch 130 through the rack gear 132. Therefore, the state as shown in FIG. 6 changes from the state shown in FIG. That is, the latch 130 is separated from the fastening hole 702 of the door frame 700 to open the door 600.

After a predetermined time, as the driving force of the solenoid 230 is removed by the control of the first CPE 418, the driving shaft 234 moves upward by the restoring force of the restoring spring 236. Therefore, the connection between the drive shaft 234 and the connector 250 is released, and the door 600 cannot be opened.

On the other hand, if it is determined that the composite code signal detected by the first CPE 418 and the secret code input to the first memory 420 are not identical, the first CPE 418 drives the driver 422. Don't let that happen. Therefore, as shown in FIG. 10, since the second coupling piece 244 is not inserted into the second coupling groove 252 of the connector 250, the rotational force is not transmitted to the key lever 260 even when the outer lever cap 210 is rotated. Do not. And since the latch 130 is maintained in the state as shown in FIG. 7, the door 600 cannot be opened.

If the third screw 214 fastening the outer lever 210 to the interlocking lever 220 in order to open the door 600 steplessly, and the outer lever 210 is separated from the interlocking lever 220, the interlocking lever ( 220 is firmly coupled to the attachment plate 290 and the size thereof is small, and the material is also made of special steel, so that the door 600 cannot be opened.

At this time, the control device 400 detects an impact from the impact sensor 430 and rings the buzzer 450, thereby reducing the willingness of the illegal intruder or warning the user of the theft so as to take appropriate measures.

In addition, when the power supply of the first power supply 460 is insufficient, the control device 400 turns on the lamp 440 through the driver 422, thereby notifying that the power supply is insufficient. Therefore, the user checks the lighting of the lamp 440 and replenishes the power of the first power supply 460.

On the other hand, when the door 600 is locked, the switch 530 of the secret code input device 500 is pressed in the same way as when the door 600 is opened, and the outer lever 210, the interlock lever 220, and the solenoid ( The drive shaft 234 of the 230, the connector 250, and the key lever 260 is connected to make a state that is integrally rotated. Then, by rotating the outer lever 210 in the reverse direction to rotate the disc gear 140 in the reverse direction through the key lever 260, the latch 130 is transferred in the reverse direction and fastened to the fastening hole 702 of the door frame 700. This locks the door 600.

On the other hand, when the user is indoors when opening or locking the door 600 in the interior of the door 600, by rotating the inner lever 150, which rotates integrally with the disc gear 140 of the locking device 100 outside The same action as when rotating the lever 210 can be obtained.

And when fixing the latch 130 in the room, by pressing the stopper 118 to overcome the elasticity of the fixing piece 120 and the fixing piece 120 from the lower locking groove 119 to the upper locking groove 119. By moving, the lower end of the stopper 118 is inserted into the stopping groove 134 of the latch 130 to fix the latch 130.

In this case, when moving the latch 130, lift the stopper 118 to overcome the elasticity of the fixing piece 120 and the fixing piece 120 from the upper locking groove 119 to the lower locking groove 119. By moving, the lower end of the stopper 118 is separated from the stopping groove 134 of the bolt 130 to move the bolt 130.
