Abstract

A punched card key push-type door lock, according to the present invention, includes a housing, a key insertion part, an operating rod, a key recognition part, and a motion transmission part. The keyinsertion part has a punched card key inserted therein, is guided by the housing so as to move in the direction in which the punched card key is inserted and pushed, and receives elastic force in thedirection opposite to the push direction of the punched card key. The operating rod is supported by the housing so as to be forwardly and reversely rotatable, thereby locking or unlocking a lock cylinder. The key recognition part recognizes punched patterns and un-punched patterns of the punched card key during pushing of the punched card key. The motion transmission part transmits a push movementof the punched card key as forward and reverse rotational movements of the operating rod when the key recognition part successfully recognizes the punched card key.

Description

technical field [0001] The present invention relates to a door lock, and more particularly, to a door lock using a method of identifying a punch card key to perform locking or unlocking. Background technique [0002] In general, a door lock is a device installed on a door and configured to lock the door to a door frame or unlock a locked state of the door according to a user's operation. Recently, the use of digital door locks employing a password input method, a fingerprint recognition method, and a radio frequency (RF) method is gradually expanding in order to improve security reliability and usability. In the event of a circuit failure or power outage, these digital door locks may not function as a door lock. [0003] Meanwhile, an example of a card key identification method has been disclosed in Korean Registered Patent No. 0528505. According to this technique, a card is provided in a form formed with a plurality of perforations, and when punches and perforations forme...
