Referring to the digital automatic door lock device according to the present invention having such a configuration in more detail based on the drawings as follows.

Figure 2 is a forward exploded perspective view according to the present invention, Figure 3 is a rear exploded perspective view of the present invention and Figure 4 is a front view showing the overall configuration of the device combined perspective view of the present invention. First, as shown in FIG. 2 to FIG. 3, the digital automatic door lock device of the present invention is installed in the door to penetrate the main body 10 in which each component of the door locking device is located, and the upper head portion of the main body 10. The plurality of first magnet sensors 11 are inserted into the ball 27 to confirm whether the door is locked, and fixed to the recesses 28 on both sides of the upper end of the main body 10, respectively. The electric signals from the solenoid 13 are interpolated into the plurality of limit switches 12 and the through holes 29 on one side of the lower part of the main body 10 by receiving an electrical signal from the plate 26. The second magnet sensor 14 for detecting the operation is located. In addition to the sensor and the limit switch 12, the first shaft 15, which is vertically vertically moved according to the application of power in the solenoid 13, is fixed to the operating piece 16 with a pin 17 to fix the body. 4 is fixed to the fixing groove 31 of the main body 10 with the long pin 30 as shown in FIG. On the other hand, the guide roll 19 and the second shaft 20 is fixed to the pin 18, when the door opening and closing the guide roll 19 is maintained in a state capable of rotating left and right, the first spring 24 is The second shaft 20 is enclosed in the upper end recess 31 in the front of the body 10 in the form of surrounding the outer periphery. In addition, a flange 22 is formed at one side, and the second spring 25 is positioned at the outer circumference of the lock 21 in which the permanent magnet 23 is fixed to the inside thereof. 4), a cover 33 for protecting the main body 10 from external impact is screwed with the main body 10 as shown in FIG.

Referring to the operation of the embodiment of the digital automatic door lock device according to the present invention having such a configuration in more detail, when the door is closed in the open state as shown in Figure 5 in the door frame plate 34 installed in the door frame As described above, the guide roll 19 is rotated at a predetermined angle in a line contact state instead of point contact by a conventional ball structure, and the second shaft 20 connected by the guide roll 19 and the pin 18 is retracted together. As the plate 26 fixed to one end of the second shaft 20 is screwed as well, the limit switch 12 is turned on, as shown in FIG. 6, and the second shaft 20 is The first spring 24 surrounding the circumference is to maintain the compressed state. At the same time, in the present invention, the first magnet sensor 11 as described above is introduced as a means for recognizing whether the door is completely closed. As shown in FIG. 8, the first magnet is completely closed. The permanent magnet 35 is positioned at a predetermined position of the door frame corresponding to the position of the sensor 11. Therefore, when the door is completely closed, the electrical signal due to the generation of the magnetic field is transmitted to the limit switch 12 so that the locker is satisfied when the electrical signal and the ON state of the limit switch 12 are satisfied at the same time. (21) is to operate in a locked state. That is, when the above condition is satisfied, power is applied to the solenoid 13 from the outside, and as the first shaft 15 descends, the guide groove of the operating piece 16 connected to the first shaft 15 by the pin 17 is provided. The door 37 is rotated at a predetermined angle so that the door 37 is fully locked as the contactor 37 of the operation piece 16 linked thereto moves the locker 21 forward. At this time, in the present invention, even if the door closing condition is satisfied by inserting the second magnetic sensor 14 into the lower part through-hole 29 of the main body 10, the solenoid 13 is inoperative, that is, the locker. If 21 is not advanced, the person from the usual warning means (not shown) is made to recognize that the door is not locked. Such a function is performed by the permanent magnet 23 fixed inside the second magnet sensor 14 and the rear flange 22 of the locker 21, and the door is closed as opposed to the first magnet sensor 11. Although the condition is satisfied, it is designed to sound an alarm when it detects that a magnetic field is still generated from the second magnet sensor 14. On the other hand, when the power supply to the solenoid 13, the reason why the first shaft 15 is configured to descend in the direction of gravity is to prevent unnecessary power consumption, unlike the case where the first shaft 5 is configured to rise (about 500 mA) Compared to the above, the driving is performed with less electric energy (300 mA), and the shape of the locker 21 is also a technical concept of a hollow cylinder type with an empty inside as shown in FIG. 7. Because. On the other hand, Figure 9 is a bar opening state diagram according to the present invention, when the door is to open when the signal from the normal control unit (not shown) by a conventional card input unit or button operation unit when the restoring force of the second spring 25 By this operation piece 16 is reversed, the first shaft 15 is returned to the raised state.

According to the present invention as described above, when the ON state of the electrical signal and the limit switch 12 by the first magnet sensor 11 is satisfied at the same time, the locker 21 is configured to operate in the locked state. Accordingly, when the fully closed condition of the door is not satisfied, not only can the malfunction of the locker 21 be prevented in advance, but also the above fully closed condition is satisfied by introducing the second magnet sensor 14. When the solenoid is not in operation, the user can recognize that the door is not locked, and the power can be saved by improving the structure of the locker 21 and the driving conditions of the first shaft 15. Since the roll 19 is made in line contact when the door frame plate 34 is in contact, it can prevent malfunction due to wear and foreign matter being caught. This can provide easy digital auto door locks.
