Door lock and method for manufacturing said door lock

A method for locking a door to an underlying structure, the method comprising:

• providing a machine element connected to the underlying structure, the machine element comprising flange portions extending from a receiving portion, the receiving portion comprising first and second end portions extending outwardly from the flange portions in opposed directions, the first end portion being positioned in an opening of the underlying structure and the flange portions being connected to an inside surface of the underlying structure next to the underlying structure opening, the first end portion comprising inclined surfaces creating a receiving part and the second end portion comprising internal threads;
• providing a bushing element securely arranged in an opening of the door, the bushing comprising an inclined protruding part and a channel;
• and
• providing a bolt member comprising a head portion and a threaded end portion;
• wherein, when the door is moved toward a locking position within the underlying structure, the protruding part of the bushing member is received in the receiving part of the receiving portion so that the bolt member can be inserted therethrough, so as to threadably engage the bolt member with the threads of the second end portion of the receiving portion, locking the door against the underlying structure.
