In addition, it is preferable that a predetermined section of the end of the rotation shaft 113 forms an outer diameter consisting of at least one plane and a curved surface.

6 to 7 are partially enlarged cross-sectional views showing the structure of the lever operation unit and the electronic operation unit of the electronic door lock device according to the present invention, the electronic operation unit 200 as shown in the figure is a straight line according to the electrical polarity change The solenoid valve 210 for reciprocating motion, the free end 221 that is matched to the linear motion portion 211 of the solenoid valve 210, and the fixed end fixed to the hinge so that the free end 221 is rotated by a certain radius Rotating member 220 formed of the end 223, the upper end is fixed to the center of the rotating member 220 by the pin 231, the lower end is inserted into the key guide groove 121 of the shaft coupling portion 120 While being reciprocated up and down, the fixed key 131 of the shaft fixing means 130 is composed of a key interrupting member 230 to control the entry into the key guide groove 121.

Here, the solenoid valve 210 may drive a motor so that the linear movement part 211 reciprocates, or a solenoid valve may be used.

In addition, the signal input unit 300 as shown in FIG. 3 includes a keypad 310 combined with Arabic numerals or special characters and a sensor unit 320 capable of sensing external information.

In addition, the power supply means 400 shown in FIGS. 3 to 4 forms an internal power input terminal 410 on the back of the case 500, and a power supply unit including one or more storage batteries in the internal power input terminal 410. When 420 is connected and the internal power source is not available, an external power source input terminal 430 is further formed on the front surface of the case 500 in order to connect the power source from the outside.

The present invention made of the configuration as described above is to lock / unlock the central locking device of the drawer cabinet through the electronic door lock device, the operation state according to the present invention in detail as follows.

First, a password may be input using the keypad 310 of the signal input unit 300 or the setting information may be sensed through the sensor unit 320.

At this time, when the input information and the pre-stored information value is matched, the electronic operating unit 200 is operated. As the polarity of the current applied to the solenoid valve 210 of the electronic operating unit 200 is converted, the solenoid valve The linear reciprocating motion is performed in the linear motion part 211 of 210.

That is, as shown in FIG. 6, the linear movement part 211 that has been raised upward is moved downward as shown in FIG. 7. At this time, the free end 221 of the rotation member 220 is in a state in which the linear movement unit 211 is matched, and as the linear movement unit 211 is moved, the rotation member 220 is centered on the fixed end 223. It will be rotated by a certain radius.

At this time, the center of the rotating member 220, the upper end of the key clamping member 230 is fixed with a pin 231, the lower end is inserted into the key guide groove 121 of the shaft coupling portion 120, the key While pressing the fixed key 131 entered in the guide groove 121 is moved to the lower side.

When the key interrupting member 230 is moved to a boundary point between the inner diameter of the shaft coupling portion 120 and the outer diameter of the pivot shaft 113, the key interlocking member 230 is released to rotate the lever 110. That is, the fixing key 131 of the shaft fixing means 130 is rotatable on the inner diameter surface of the shaft coupling portion 120.

To this end, the tip of the fixing key 131 is preferably rounded.

In the above state, when the lever 110 is rotated in the open direction, the rotation shaft 113 is rotated, thereby rotating the operation bar 140 coupled to the end of the rotation shaft 113 together.

At this time, the operation bar is to operate the central locking device of the drawer cabinet to release the lock state of each drawer.

Here, the central locking device is formed on the bottom of each drawer of the multi-stage locking grooves to control the movement in the horizontal direction, the locking mechanism of the principle that the locking grooves are simultaneously locked and released to the latch reciprocating in the vertical direction As referring to the apparatus, this is a generally well-known technique, and description thereof will be omitted.

Then, when the drawer according to the present invention to lock the operation, first, while the linear movement portion 211 of the solenoid valve 210 is moved to the top, it rotates the rotating member 220 together.

At this time, the key interrupting member 230 coupled to the center of the rotating member 220 by the pin 231 is moved to the upper portion of the key guide groove 121.

Subsequently, when the lever 110 is rotated in a close direction, the operation bar 140 that is coupled to the bar coupling portion 113b of the rotation shaft 113 is rotated, and the operation bar 140 is rotated. The clasp (not shown) of the central locking device is moved in the vertical direction so that the clasp and the engaging groove formed on the bottom of each drawer are matched and locked.

Subsequently, when the lever 110 is continuously rotated in the locking direction, the key groove 113a of the rotation shaft 113 and the key guide groove 121 of the shaft coupling portion 120 reach a point where the lever 110 coincides with each other. The fixed key 131 supported by the member 133 enters the key guide groove 121.

As described above, when the fixing key 131 enters the key guide groove 121, the manipulation of the lever 110 is impossible, and the manipulation of the central locking device is also not performed.

According to the present invention made of the configuration and operation as described above, there is no inconvenience to carry or store the key, it is possible to safely store valuables in the chest of drawers.

Through the technical contents of the present invention having the above-described configuration, those skilled in the art can recognize that various changes and modifications can be made without departing from the technical spirit of the present invention.

Therefore, the true technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be determined by the scope of the utility model registration request.

The present invention has the convenience of not having to carry or store the keys by intercepting the lock for the drawer using an electronic door lock, and the inconvenience of not using the drawer due to the loss of the key, or a criminal act of forging a key. There is an effect that can be prevented in advance.
