Title:
DOOR LOCK CAPABLE OF PREVENTING FORCIBLE UNLOCKING
Document Type and Number:
WIPO Patent Application WO/2013/012128
Kind Code:
A1
Abstract:
The present invention relates to a door lock capable of preventing forcible unlocking by preventing movement of an elevating member when an attempt is made to unlock the door lock using a tool from the outside. The door lock of the present invention moves the elevating member vertically by rotating a bevel gear, coupled to a rotating plate, in forward and reverse directions by means of a drive motor. The door lock consists essentially of: a plate forming a guiding portion in which a fixing pin, fixed to the body of the elevating portion, is inserted; and a locking metal piece formed on one side of the plate, and inserted into or withdrawn from a catching piece, so as to switch to a locked state or an unlocked state. The plate has a rotating plate that rotates so as to elevate the elevating member, and the front end of the rotating plate is attached to the outer periphery of the rotating plate, so that a lower stop pin and an upper stop pin for arresting a forcible movement of the elevating member are arranged in vertical increments and formed so as to project forward.
