Claims

[Scope of utility model registration request]

(1) A gap is provided between the outer frame of the door and the lock mounting surface of the door body, and the latch of the door body is hooked on the latch receiver fixed to the outer frame of the door corresponding to this gap. A door lock device configured to prevent the door from opening includes a case fixed to an outer frame, and a latch receiver fitted into the case so as to be movable in and out in the direction in which the latch enters and exits. It consists of an entry/exit locking box and an extruded plate enlarged and bent between the entry/exit locking box and the case, and the front side of the entrance/exit locking box protrudes from the front of the case and is fitted into the case. A gap is formed between the bottom of the locking box and the inner surface of the bottom of the case so that the locking box can be inserted into the case, and a large extrusion plate is provided in this gap. Although this extruded plate can be bent, it has inelasticity that allows it to maintain its bent state.When the outer frame of the door is distorted and the door body presses on the locking box, the extruded plate is pushed in, and after bending. A door lock device characterized in that it is configured to maintain this pushed-in state.

(2) The amount of protrusion of the locking box from the front of the case is 3 to 12
A door lock device as set forth in claim (1) of the utility model registration claim.
