The present invention relates to a door locking device, and more particularly, to an actuator of a door locking device for locking a door that opens and closes the inside of a cabinet constituting the exterior of a media storage box to a cabinet, and a door locking device having the same.

Media storage box refers to a device for storing media such as banknotes, checks, tickets, and documents. Media storage box is used, for example, as a device for paying media at the request of a customer in a safe or a bank or a public office.

1 is a rear view showing a rear appearance of a media storage container according to the prior art.

As shown, the appearance of the media storage box is formed by the cabinet 2. One side of the cabinet 2 is rotatably provided with a door 4 for selectively opening and closing the inner space of the cabinet 2. The outer surface of the door 4 is provided with a key bundle 6, and a lock handle 8 is installed at a position adjacent to the key bundle 6. The key bundle 6 may be operated by a user with a key, and the lock handle 8 may perform locking and releasing operation of the door lock device in a state where the key bundle 6 is released.

Figure 2 is a front view showing the configuration of the door lock device of the media storage container according to the prior art.

According to this, a link 10 driven by the key bundle 6 is rotatably installed on the rear surface of the door 4. An actuator 12 is installed on the rear surface of the door 4 adjacent to the key bundle 6. The actuator 12 is driven by the lock handle 8.

The actuator 12 is installed so that the lifting piece 14 driven by the locking handle 8 enters and exits in the vertical direction with reference to the drawings. The elevating piece 14 is limited to the entry and exit by the link 10. That is, the link 10 is installed to block the lifting piece 14 from moving or to be rotated so as not to interfere with the movement of the lifting piece 14.

Connection bolts 16 are respectively connected to both ends of the actuator 12, and the connection bolts 16 are externally together when the lifting piece 14 protrudes to the outside by driving the locking handle 8. It protrudes. Of course, the direction in which the connecting bolt 16 protrudes is a direction perpendicular to the lifting piece 14. A predetermined mechanism is provided inside the actuator 12 to produce the operation of the elevating piece 14 and the connecting bolt 16. The inside of the actuator 12 is provided with a configuration such as a link and a pin for changing the rotational movement of the key bundle 6 to a linear movement.

One side of the connecting bolt 16 is connected to the first connecting bar 18. The first driving bar 20 is fixed to the first connection bar 18. The first driving bar 20 extends long in the vertical direction of the door 4. First locking bars 22 are provided at both ends of the first driving bar 20, and the first locking bars 22 are selectively seated in grooves (not shown) on the cabinet 2 side to open the door. (4) is locked to the cabinet (2).

And, the support bar 24 is connected to the other side of the connecting bolt 16. The support bar 24 is integrally operated with the connecting bolt 16. The support bar 24 is supported at its tip through a bracket provided on the rear surface of the door 4. Of course, the support bar 24 is also used for locking the door 4 by hooking it to the cabinet 2 side.

On the other hand, the second connecting bar 26 is provided to protrude to the opposite side of the lifting piece (14). The second connecting bar 26 is connected to the member protruding from the inside of the actuator 12. The second connection bar 26 is also operated in conjunction with the operation of the lock handle (8). The second driving bar 28 is orthogonally installed at the front end of the second connection bar 26, and the second locking bar 30 is provided at the front end of the second driving bar 28, respectively. The second locking bar 30 is also selectively seated in a groove (not shown) on the cabinet 2 side to allow the door 4 to be locked to the cabinet 2.

In the prior art having such a configuration, a user rotates the link 10 only by a certain angle in the state of FIG. 2 by manipulating the key bundle 6 using a key. In this case, the lifting piece 14 is in a state in which it can protrude to the outside. Therefore, when the user rotates the lock handle 8, the lifting piece 14 may protrude to the outside.

At this time, the elevating piece 14 is protruded to the outside by the operation of the lock handle 8 and the connecting bolt 16 and the second connecting bar 26 is operated to enter the inside of the actuator 12. . That is, the driving bars 20 and 28 are respectively moved in the direction of the arrow of FIG. Thus, the locking bars 22 and 30 are released from the recesses on the cabinet 2 side, respectively, and the locked state of the door 4 is released.

For reference, closing the door 4 so that it is in a locked state may cause the locking bars 22 and 30 to enter the grooves on the cabinet 2 side by rotating the locking handle 8 once, and the key. By operating the bundle 6, the link 10 may be blocked so as not to protrude to the outside of the elevating piece 14.

However, the door lock device of the media storage according to the prior art as described above has the following problems.

First, when the user wants to open the door 4, the key bundle 6 is first rotated so that the lifting piece 14 can be moved, and then the locking handle 8 is rotated to one side to actuate the actuator. (12) is to be operated. That is, since the process of opening the door 4 is made in two steps, there is a problem that the user is inconvenient and the configuration of the door locking device is complicated.

Next, the actuator 12 is provided with a configuration such as a link and a pin to change the rotational movement of the locking handle 8 to the linear movement of the elevating piece 14 and the connecting bolt 16. In order to operate the actuator 12 smoothly, a certain tolerance exists between components, and there is a problem in that flow occurs when the locking handle 8 rotates.

Accordingly, an object of the present invention is to solve the problems of the prior art as described above, and to provide an actuator of a door locking device having a relatively simple configuration and a door locking device having the same.

Another object of the present invention is to provide an actuator of a door locking device which can be operated in one operation and a door locking device having the same.
