Hereinafter, with reference to the accompanying drawings a preferred embodiment of the door lock device according to the present invention will be described.

Fig. 1 shows the appearance of a safe 1 used in a teller machine such as a cash dispenser. As shown in FIG. 4, the safe may be provided with an object 50 therein and a cash cassette for accommodating cash. The front opening of the object 50 may be opened and closed by the door 20. The door 20 is generally made of steel or steel alloy or the like, and is generally openly connected to the safe 1 using a hinge 60 as shown in FIG. 4. The door handle 22 is rotatably coupled to the outer surface of the door 20.

A locking plate 30 may be provided inside the door 20 to selectively restrain the door 20 to the object 50. The locking plate 30 is formed in the shape of a generally rectangular flat plate, but may be configured as a flat plate having various shapes according to requirements. The locking plate 30 may slide up and down according to the rotation operation of the door handle 22 to restrain the door 20 to the safe 1.

2 and 3 will be described in detail with respect to the door 20 locking device of the present invention.

2 is a view showing the inner side of the door 20 when the door 20 is locked to the safe 1 and locked.

Referring to FIG. 2, the locking plate 30 interlocks with the rotating piece 31 and the locking assembly 32 such that the door 20 is restrained or restrained by the safe 1. To this end, the guide plate holes 34 and 36 are formed in the locking plate 30, and the guide protrusions 33 and 35 sliding in the guide holes 34 and 36 are formed on the inner surface of the door 20. It is prepared. In addition, a shaft 312 serving as a pivotal axis of the rotating piece 31 is formed on the inner side of the door 20 so that the locking plate 30 and the rotating piece 31 are outside the door 20. It extends to the side handle 22.

In addition, as can be seen in Figure 2, the stopper (311, 313) for limiting the range of motion of the rotary piece 31 may be formed. In the accompanying drawings, for example, the pin 311 for limiting the upward movement range of the rotary piece 31, and rotates when the rotary piece is rotated in a clockwise direction, for example, to convert from the locked state to the locked rotation state Constraints 313 are shown to limit the range of rotation of the piece 31 in the clockwise direction.

In addition, the rotation piece 31 is preferably a combination of a rectangle and an arc shape so as to move the locking plate 30 up and down while turning about the shaft 312 in accordance with the rotation of the handle (22). It is produced in the form.

One side of the door 20, that is, one side of the door 60 is formed with a plurality of locking pins 44 to operate in conjunction with the vertical movement of the locking plate 30. The locking pins 44 are inserted into the insertion holes of the first locking plate 54 and slide in the long holes 45 formed in the guide plate 51. As the locking pins 44 slide up and down, the first locking plate 54 also slides up and down with respect to the guide plate 51. The guide plate 51 is formed integrally with the door 20, and the first locking plate 54 is coupled to the guide plate 51 through the locking pins 44. The first locking plate 54 extends in the longitudinal direction of the surface of the door 20. As a result, since the locking plate 30 is fixed to the first locking plate 54 by a fixing pin (not shown), the locking plate 30 and the first locking plate 54 are together with the door 20. It is possible to slide with respect to the guide plate 51 formed integrally in the.

On the opposite side where the hinge 60 of the door 20 is formed, a second locking plate 52 formed to face the first locking plate 54 is provided in the door. In addition, the second locking plate 52 is provided with a hook 40 on the opposite side of the inner surface of the door 20. Preferably, the hook 40 is arranged at a predetermined interval along the longitudinal direction of the second locking plate (52). In addition, a plurality of locking plates 41 that can be coupled to the hook 40 are provided in the longitudinal direction of the door 20. The locking plate 41 may be preferably formed in a plate shape to be coupled to the hook 40, the plate surface of which faces the inner surface of the door 20.

Preferably, between the hook 40 and the extension part 70 of the outer surface of the door 20, which the padding plate 42 which pads the hook 40 in a direction parallel to the second locking plate 52 will be described later. In the door 20 is formed integrally. As a result, even when the gap between the object 50 of the safe 1 and the door 20 is attacked from the outer side of the door 20, the hook 40 is not immediately exposed, thereby delaying the unlocking of the door. You can expect the effect.

In addition, the right and left ends of the door 20, that is, the first locking plate 54 and the second locking plate 52 are provided, and the locking plate 30 is provided in parallel with the inner surface of the door 20. Since the reinforcing steel plate 43 is integrally formed in the door 20 in the longitudinal direction of the door 20, the first locking plate 54, the second locking plate 52, and the locking plate 30 attack from the outside. Even when faced with the reinforcing steel plate 43 may delay the opening of the safe 1.

In addition, a long hole 47 for guiding the slide motion of the second locking plate 52 and a guide pin 46 sliding in the long hole may be provided. The long holes 45 and 47 and the locking pin 44 and the guide pin 46 sliding in each of them guide the first locking plate 54 and the second locking plate 52 to slide up and down, respectively. And a function of limiting the range in which the first locking plate 54 and the second locking plate 52 slide up and down.

Therefore, by adopting the adding plate 42, the reinforcing steel plate 43 and the extension portion 70 it is possible to obtain an effect that can improve the security performance even when the safe 1 is subjected to an external attack.

FIG. 2 illustrates a state in which the door 20 is restrained by the safe 1, and FIG. 3 illustrates that the object 20 is released from the safe 1 by the door 20. ) Can be exposed to the outside.

In the restrained (or locked) state of FIG. 2, when the handle 22 outside the door 20 is rotated clockwise, for example, an arc-shaped portion of the rotating piece 31 is guided by the pin 311. Will rotate. The restraining piece 313 serves to limit the range in which the rotating piece 31 rotates in the clockwise direction. At this time, since the pin 311 acts as a stopper, the locking plate 30 moves upward due to the rotational force of the rotating piece 31. At this time, the upward movement of the locking plate is guided by the guide holes 34 and 36 formed in the door plate and the guide protrusions 33 and 35 sliding therein, and the guide protrusions 33 and 35 are guide holes. The locking plate 30 moves upward until it comes in contact with the bottom surfaces of 34 and 36.

The rotary piece 31 and the door handle 22 are connected by the door shaft 312, and the rotational force of the door handle 22 is applied to the rotary piece 31 through the door shaft according to the rotation operation of the door handle 22. Can be delivered. Accordingly, the rotary piece 31 may rotate in conjunction with the door shaft 312.

In addition, referring to FIG. 5, as one end of the object 50 of the safe 1, a plurality of binding holes 48 are formed at positions corresponding to the positions of the hooks 40. When the hooks 40 are inserted into and engaged in the binding hole 48, the door 20 is locked to the safe 1.

When the locking plate 30 slides upward, the first locking plate 54 and the second locking plate 52 interlocked with the locking plate 30 move upward. Therefore, the locking pin 44 moves upward in the long hole 45 formed in the guide plate 51. At the same time, while the binding of the hooks 40 bound to the binding hole 48 is released, the restraint (locking) of the door 20 is released.

On the contrary, when the handle 22 is rotated counterclockwise, for example, in the restrained state of the door 20, the rotational force of the rotating piece 31 causes the locking plate 30 to slide downward. When the locking plate 30 slides downward, the first locking plate 54 and the second locking plate 52 interlocked with the locking plate 30 simultaneously slide downward, and at the same time, the locking pin 44 is in the long hole 45. Sliding downwards and eventually seated on the bottom surface in the long hole (45).

2A and 3B, respectively, the enlarged state of the engaging state and the disengaging state of the hook 40 and the engaging plate 41 at the time of restraint and restraint are respectively enlarged.

4 illustrates a state in which the door 20 is restrained. When an extension part 70 is formed at one side of the door 20, the gap between the door 20 and the safe 1 is attacked. To improve the security performance. In addition, the extension part 70 may be formed on the other side of the door. Therefore, even when the hinge 60 is attacked, the security of the safe 1 can be improved.

In addition, referring to FIG. 4, it can be seen that an insertion hole 53 into which the locking pin 44 formed at the link side of the door can be inserted is formed in the object 50. In addition, the plate forming the insertion hole 53 is preferably formed using the same material integrally with the object. For this reason, compared to the case where the insertion hole is in the door 20 and the locking pin is formed in the object 50, the fastening force is excellent.

The locking assembly 32 provided inside the door 20 is a component that restricts the slide movement of the locking plate 30 by selectively limiting the slide movement of the guide protrusions 33 and 35.

In addition, referring to FIG. 5, the locking plate 30 may be restrained or restrained by a clamp 37 protruding from the lock assembly 32 inside the door 20.

The locking assembly 32 may be provided with a locking module 21 installed to expose a part of the door 20 to the outside. Here, the locking module 21 refers to a key locking module, a dial locking module or a keypad (usually provided in the object 50 such as a safe so that only a specific user can open and close the object 50). key-pad) locking module. The clasp is mechanically or electrically connected to the locking module 21.
