Description

Door key box structure of button type door lock

The present invention relates to a door key box structure of a button-type door lock, and more specifically, the internal structure of the door key box is mechanically configured so that the door lock part does not malfunction even when an external shock is transmitted or an electric shock is transmitted, It relates to a door key box structure of a button-type door lock configured to selectively operate the first operation piece according to the rotation of the rotating piece to operate the door lock portion for a long time even with a small amount of power.

In general, various doors are provided with door locks for security purposes, and the door locks are configured to selectively lock and release the doors. Briefly describing a conventional door locking device, a key holder having a key groove is installed to open and close a door by operating a locking lever by inserting a key out of a locking device in which the locking lever and the locker are installed. The door lock device can open and close the door by operating the lock lever installed in the door lock device to open and close the door from the inside of the door. When the door is out, the door lock lever can be locked by operating the door lock lever with a key. It is. Recently, a button-type button is designed so that the door-lock part can be unlocked by installing a separate button body arranged horizontally on the door member surface where the outer handle is fixed in the door lock, and pressing the plurality of buttons displayed on the button body in the order of their unique numbers. Door locks have been developed. The button-type door lock is configured such that the door lock part is selectively locked and released by an electronic (solenoid valve). The button-type door lock has a power supply unit for selectively supplying power to the solenoid valve.

By pressing the unique number in sequence using the button-type door lock configured as described above, the door could be locked and released, but such a button-type door lock has a problem in that the reliability of the product is deteriorated to the user because often a malfunction occurs. That is, since the means for selectively locking and releasing the door lock part is constituted by an electronic solenoid valve, the door lock part is delivered when a predetermined shock (impact that the door contacts the door frame) or an electric shock is transmitted to the door. There was a problem of malfunction due to the impact.

In addition, since the means for selectively locking and releasing the door lock part is constituted by an electronic (solenoid valve), there is an inconvenience in that the battery must be replaced at any time. In other words, the solenoid valve that operates the door lock in the horizontal direction requires a large amount of power to operate the battery, and there is an inconvenience in that the battery needs to be replaced from time to time, and in order to replace the battery, the button type door lock is removed from the door. There is a problem that takes a lot of time to be replaced.

Therefore, in view of the above-described problems according to the present invention, the object is to construct the internal structure of the door key box mechanically, even if the shock is transmitted from the outside or the electrical shock is transmitted, the door lock does not malfunction and at the same time the rotational opening and The first operation piece is configured to be selectively operated in accordance with the rotation of the rotation piece to provide a door key box structure of the button-type door lock that can operate the door lock portion for a long time even with a small amount of power.

By the coupling is preferably fixed to one side of the door key box 10.

The state in which the door key box of the button-type door lock configured as described above is operated and the effects thereof will be described.

First, when the door is locked to the door frame, first, the push button (not shown) mounted on the outer touch unit (not shown) in a state in which the door is in close contact with the door frame in order of a unique number. When the unique number is sequentially input by the push button, the rotational opening 34 is rotated at a predetermined angle as shown in FIGS. 2 and 3 due to the driving of the driving motor (not shown). When the unique number is sequentially input by the push button because the driving shaft of the drive motor selectively forward and reverse rotation is inserted into the coupling hole 32 of the rotational hole 34, the unique number is sequentially input. The pupil 34 is rotated at a predetermined angle. When the rotating hole 34 is rotated by a predetermined angle due to the drive of the drive motor, the rotating piece 36 is rotated to one side by the pressing piece 48. Since the pressing piece 48 is elastically supported to one side by the coil spring, and the rotating hole 34 is rotated at a predetermined angle, the pressing piece 48 moves the rotating piece 36 to one side by the elastic force of the coil spring. Elastic support. At this time, the locking projection protruding downward at the free end of the second blade piece 40 of the rotation piece 36 is moved outward from the hook piece of the moving piece 62 and at the same time protrudes at the upper end of the first operating piece 20. The rotation distance of the rotating piece 36 is limited by the configured second hinge pin 24. Even if the lever is rotated because the locking jaw protruding downward from the hook piece of the moving piece 62 is moved outward by the second blade piece 40 of the rotating piece 36 by the rotation of the rotating hole 34. The first operation piece 20 does not operate, and the second operation piece 50 has a state moved in the horizontal direction.

When the door is released from the door frame, first, the push buttons mounted on the external touch unit are input in the order of their unique numbers. When the unique number is sequentially input by the push button, the rotational opening 34 is rotated at a predetermined angle as shown in FIGS. 4 and 5 due to the driving of the driving motor. When the unique number is sequentially input by the push button because the driving shaft of the drive motor selectively forward and reverse rotation is inserted into the coupling hole 32 of the rotational hole 34, the unique number is sequentially input. The pupil 34 is rotated at a predetermined angle. When the rotating hole 34 is rotated by a predetermined angle due to the driving of the driving motor, the pressing piece 48 and the rotating piece 36 rotated to one side by the elastic force of the coil spring are moved to the first position. At this time, the locking projection protruding downward on the free end of the second blade piece 40 of the rotating piece 36 has a state in contact with the hook piece of the moving piece 62. When the lever is rotated because the locking jaw protruding downward from the second blade piece 40 of the rotation piece 36 contacts the hook piece of the moving piece 62 by the rotation of the rotation hole 34, The operation piece 20 and the second operation piece 50 are operated at the same time so that the door is released from the door frame.

Since the structure of the door key box 10 is mechanical, the door lock part does not malfunction even when an external shock is transmitted or an electrical shock is transmitted, thereby increasing the reliability of the product to the user. In addition, since the first operating piece 20 is configured to be selectively operated according to the rotation of the rotating hole 34 and the rotating piece 36, the door lock part can be operated for a long time even with a small amount of power, and the battery is relatively low. The number of replacements can be reduced.

As described above, the door key box structure of the button-type door lock according to the present invention has a mechanical structure of the door key box, so that the door lock part does not malfunction even when an external shock or electric shock is transmitted. Reliability can be increased and at the same time, the first operating piece is selectively operated according to the rotation of the rotating hole and the rotating piece, so that the door lock can be operated for a long time even with a small amount of power.
