The present invention relates to a digital door lock installed in the door, and more particularly, to a digital type door lock opening and closing device installed for opening and closing doors, such as lockers, cabinets, safes, such as sauna facilities.

In general, the locker, the cabinet, the safe, the locker, such as to keep the belongings or valuables to the lock to install the locking member using a locking member to prevent the risk of theft and loss.

Such a locking device may be formed in various forms, but it may be classified into a manual type using a key directly inserted and a digital type operated when the same number combination system is input through a button or a fingerprint recognition.

Both the manual and the digital locks are the same in terms of storing the goods, but the digital locks are being used more and more because the digital is superior to the manual in terms of security.

On the other hand, in the conventional digital locking device, a push rod having a solenoid and a slide pin is installed inside the outdoor case to supply power to the solenoid according to a signal transmitted through the input means, so that the slide pin moves inside the solenoid, It will lock and unlock the lock.

In other words, when the spring is installed on the outside of the slide pin so that power is supplied to the solenoid, the slide pin moves to the inside of the solenoid while overcoming the elastic repulsive force of the spring, thereby releasing the turning hole to open the door.

At this time, the power is supplied to the solenoid for about 15 seconds from the time when the lock is unlocked, and the door can be opened only by rotating the pivot in the forward direction within this time. The door is locked by turning it in the reverse direction.

However, the digital locking device must continuously supply power to the solenoid so that the slide pin moving inside the solenoid in the process of opening the door maintains the reverse state for a predetermined time, so that power consumption occurs until the door key is inserted. In addition, if the door key is not inserted into the key bundle within 15 seconds, the power supply is cut off to prevent excessive loss of power, and the solenoid operation is released, causing the user to enter a password once again.

The present invention has been made in view of the conventional problems as described above, to minimize the power consumption applied to drive the solenoid during the operation of the digital door lock so as to maximize the waiting time of the rotation state that can be rotated after entering the password. The purpose is to.

The above object is provided to be rotatable around the rotation shaft in the door lock body, the rotation hole is formed with an insertion groove on one side; A slide pin installed to be inserted into the insertion groove to limit the rotation of the rotation hole; A solenoid for linearly moving the slide pin; A first spring elastically supporting the slide pin in the solenoid; Between the solenoid and the rotating hole it is possible to achieve through the digital door lock device characterized in that the blocking member is provided for limiting the slide pin retracted by the solenoid operation to move back to the original position by the elastic force of the first spring.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, referring to the internal configuration of the door lock opening and closing device according to the present embodiment through FIGS. 1 to 3, the door lock main body 1 includes a rotational opening 10 capable of rotating around the rotational shaft 11 and the rotational opening. Slide pin 20 inserted into the solenoid 21 to limit the rotation of the (10), the first spring 22 for elastically supporting the slide pin 20 in the solenoid 21, and the first It was composed of a blocking member for blocking the slide pin 20 to move forward by the elastic force of the one spring (22).

The blocking member is a blocking plate 30 provided to enable linear movement in the vertical direction to block the advance of the slide pin 20, and the second spring (31) for elastically supporting the blocking plate 30 at the rear end. ), And guide partition walls 32 formed in the door lock body 1 to guide the linear flow of the blocking plate 30.

Particularly, the insertion hole 12 into which the slide pin 20 is inserted is formed in the rotation hole 10, and the guide groove 13 to which the slide pin 20 is guided during rotation is formed as a partial section on the outer circumferential surface thereof. In the boundary portion of the guide groove 13 and the insertion groove 12, a locking step 14 is formed to form a height difference so that the blocking plate 30 can be caught.

On the other hand, the door lock cover (2) is provided with a push-type input button (3) as an example of the input means for inputting a password for the user confirmation, and the handle for turning configured to be interlocked with the rotating hole (10) ( 4) was fitted.

In addition, the rear door side of the door lock main body 1 is provided with a latch 40 is coaxially provided with the rotation shaft 11 so as to be interlocked with the rotational opening 10 which is an internal component, and the battery cover 41 is detachable. It is possible.

In the figure, reference numeral 42 denotes a battery, and 43 denotes a circuit board, respectively.

The effect of the operation of the door lock opening and closing device of the present invention constituting such a configuration will be described.

First, in the locked state of the door, the slide pin 20, which is advanced by the elastic force of the first spring 22, is inserted into the insertion groove 12 of the rotational hole 10 and is fixed as in FIG. The rotational opening 10 is to be prevented from rotating.

On the other hand, when the user inputs a pre-registered password using the input button 3 provided on the door lock cover 2 from the outside, when the input information is matched, the power is supplied for about 0.3 seconds by the electrical signal As the solenoid 21 supplied with power is magnetized, a magnetic force acts on the inside, such that the slide pin 20 moves inside while pressing the first spring 22. At this time, the blocking film 30 to which the elastic force of the second spring 31 is applied is advanced to the position of the locking step 14 of the pivot 10 as shown in FIG. 4.

Therefore, since the insertion groove 12 is covered by the blocking film 30, the slide pin 20 is inserted into the insertion groove 12 even after the power supply to the solenoid 21 is stopped and the magnetizing force is released after 0.3 seconds. The insertion is prevented to achieve a state in which the rotational opening 10 can be rotated.

The opening and closing process of the door lock according to this operation will be described in more detail through the cross-sectional views of the main parts of FIG. 5.

That is, step ST 1 is a normal state in which the door is closed. At this time, the pivoting hole 10 is not rotated as the slide pin 20 receiving the elastic force of the first spring 22 is inserted into the insertion groove 12. It is supposed to be.

In step ST 2 , the slide pin 20 is moved into the solenoid 21 where the magnetic force is generated by controlling the power supply from the circuit board 43 to the solenoid 21 for about 1 to 2 seconds through the signal of the input means. In this case, as the space for the blocking plate 30 to rise by the movement of the slide pin 20 is secured, the blocking plate 30 blocks the insertion groove 12 of the rotating hole 10. It is possible to achieve the standby state of the rotation of the copper ball (10).

In particular, the standby state in which the rotational opening 10 can be rotated as described above can be maintained even after the power supply is stopped after the initial initial power of about 0.3 seconds is supplied to the solenoid 21. It is possible to minimize the power consumption as compared to the power consumption for about 15 seconds until the rotational force of the rotational opening 10 by the user.

Therefore, after the instantaneous power supply, the standby state is maintained so that the user can rotate the handle 4 at any time without additional power consumption for the solenoid 21 operation.

And, in step ST 3 , as the user rotates the knob 4 from the outside in the forward direction, the pivoting hole 10 in the standby mode is rotated together, and the blocking plate 30 is engaged by the locking jaw 14. While being pushed down and the slide pin 20 is guided to the guide groove 13 of the rotating hole (10).

ST step 4 shows a state in which the door lock is completely opened. As such, when the user completely rotates the handle 4 to 90 degrees, the latch 40 interlocked with the pivoting hole 10 is pivoted together to rotate the door. The lock state can be released.

On the other hand, if you want to close the door is opened again by this operation is made by performing the operation to return the handle 4 in the reverse direction.

That is, when the rotating hole 10 is rotated in the reverse direction as in step ST 5 , the blocking plate 30 is no longer moved by the slide pin 20 guided along the guide groove 13.

And, as in step 6 , when the pivoting hole 10 is completely rotated to its original position, the slide pin 20 guided along the guide groove 13 is inserted into the insertion groove 12 at the position corresponding to the insertion groove 12. The door lock is locked by blocking the rotation of the rotation hole 10 while being inserted into the door.

Therefore, in this locking step, the blocking plate 30 is pushed by the catching jaw 14 to move in the direction of compressing the second spring 31, thereby preventing the slide pin 20 from being inserted into the insertion groove 12. You won't be able to.

  In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the door lock opening and closing device of the present invention may be variously modified and implemented by those skilled in the art.

For example, in the above embodiment, although the push type input button is shown in the figure as the password input means of the digital door lock, it may be equipped with a dial type input means.

In addition, the opening and closing structure of the door using a separate door key may be applied by forming a key insertion groove in the pivot.

Therefore, such modified embodiments should not be understood individually from the technical spirit or the prospect of the present invention, and such modified embodiments should fall within the appended claims of the present invention.

The present invention as described above, by applying the operating power to the solenoid instantaneously only during the initial movement of the slide pin for releasing the fixed state of the rotation hole to minimize the power consumption that was previously applied for opening and closing the door lock for a certain time It becomes possible.

In particular, since the standby mode is maintained in a state in which the restoration of the slide pin is mechanically blocked by the blocking member, the standby mode can be continued for a long time without additional power consumption.
