Description

Double Locking Device

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a double locking device, more particularly, to a double locking device in which a simple but precise and smooth locking operation is performed, and an intrusion from the outside is prevented .

In general, the locking device is installed for the purpose of controlling access, and is installed most in the door.

The locking device installed on the door is provided with a rotary knob on both sides of the door, a latch interlocked with each knob is projected on the end of the door, and a dead bolt interlocked with the lock key inserted in the knob And is protruded from the end.

That is, when the lock key is turned in one direction, the dead bolt is protruded to select the lock, and when the lock key is turned in the other direction, the dead bolt is pulled and the door is unlocked. When the handle is rotated while the dead bolt is unlocked, the latch bolt is pulled in and the door can be opened. At this time, the latch bolt is laid in a structure that allows the latch bolt to be drawn out freely, so that it can be easily pulled in by pushing it with a tool.

Therefore, the latch bolt is used only as means for opening and closing the door, and does not function to lock the door. In other words, locking and unlocking the door is made only of dead bolts interlocked with the lock key, so that there is a problem that the security capability is deteriorated.

Recently, a double locking device is installed to increase the security capability.

The conventional double locking device is provided on the indoor side of the door so that even if a user leaves the locked state outdoors, the double locking device has a structure that can not enter and leave the room without releasing the double locking device in the room.

However, since the conventional double locking device is installed separately from the handle and protrudes in a small size from the inside of the main body, it is difficult for the child or the elderly to operate it, and is located away from the handle so that the handle can be rotated quickly There is a problem that a safety accident may occur because the operation is not quick in case of emergency evacuation due to a fire.

Therefore, there is an urgent need to develop a double locking device that ensures quick operation and security.
