Claims

[Scope of utility model registration request]

A locking device for a door hinge-connected to a door support, in which a lock pin that protrudes from the door or retreats into the door when the door handle is operated is caused to protrude from the door when the door is in a closed state, and is attached to a pin receiving portion on the door support. The locking device is configured such that the door handle can be moved in a direction transverse to the direction of movement of the pin to assume a first position protruding from the door surface or a second position retracted to the door surface. , the door handle is provided with a connecting part facing in the moving direction of the pin, and the connecting part and the pin are connected so that the movement of the door from the first position to the second position is converted into a protruding movement of the pin, A door locking device, characterized in that the door locking device is connected by a conversion mechanism for converting the movement from the second position to the first position into a backward movement of the pin.
