Abstract:
The present invention relates to a door lock comprising: a first fixed element and a second fixed element fixed at the respective sides of a door; a movable rod inserted into through-holes formed at the respective first and second fixed elements so as to be movable; a press element inserted into the through-hole of the first fixed element; a drawing element inserted into the through-hole of the second fixed element; a return spring for returning the movable rod to the original state when the external force applied to the press element or the drawing element is removed; a slider which moves when external force is applied to the direction orthogonal to the movable direction of the movable rod, and returns to the original state when the external force is removed; a push rod which moves the slider when external force is applied to the press element or the drawing element and the movable rod moves; a latch bolt which moves in conjunction with the slider; a guide element for guiding the movement of the latch bolt; and a door-locking means for keeping the door in a locked state. The thus-configured door lock of the present invention enables a door to be simply opened and closed just by pushing and pulling a door handle without rotation, and can be widely used due to the door-locking means.
