Description

Door lock {ROCKING APPARATUS FOR DOOR}

The present invention relates to a door lock device, and more particularly, to a door lock device that can not be cut or damaged by a thief or another illegal intruder by installing inside and outside the personal locker of the door or locker room.

In general, the electronic key device is to release the lock of the door by the digital signal response, it is commonly applied to a personal locker of a house or office, and recently a personal safe or locker room. Representative examples of such electronic key devices include computer keys, fingerprint recognition devices, and card keys.In the case of dual card key devices, an RF chip is embedded in the card and a card reader is installed on the door surface to recognize the RF signal from the chip. The door is automatically opened by recognizing the signals.

In addition, in the case of the fingerprint recognition door lock device, a fingerprint recognition device capable of recognizing the visitor's fingerprint is installed on the surface of the door, and when the visitor touches the finger, the fingerprint recognition device identifies the fingerprint of the visitor to check whether the visitor is legitimate. .

Referring to one example of the conventional door lock shown in Figure 1, the locking device 20 is built in the locking latch 22 to prevent theft, and the locking latch 22 is inserted into the locking groove is inserted It consists of a provided bracket (not shown).

However, this type of door locking device is that the locking latch protrudes from the locking device mounted on the surface of the door 10 to be inserted into the bracket, so that a thief or intruder outside the door inserts a cutter into the door gap to sufficiently lock the door. Since the latch can be cut, in fact, the conventional door lock device has many questions about its effectiveness.

The present invention has been devised to solve the conventional problems as described above, and is installed on the inner surface of the door or the side wall of the door of the personal locker, respectively, so that the lock is made in parallel with the space between the door gaps. It is impossible to cut or damage by other illegal intruders, and when the door is forcibly opened, an alarm is automatically sounded to provide a very secure door lock device from theft or illegal intrusion.
