<p>The present invention is directed to a free-turning anti- theft device assembled in a door lock, a characteristic translated into obtaining a first subcombination cylinder with key subcombination (S1) which is mounted on a second subcombination called free-turning anti-theft subcombination (S2), wherein the first can receive all kinds of specifications of cylinder (3) with key (ch), and accordingly the cylinder (3) is now included in its constructive concept, with a lock (12) positioned at the rear of the body (3a) of the cylinder (3), where in turn the convention rear part of this cylinder is separated and now forms the unprecedented cylinder terminal (4) which is mounted inside the free-turning anti-theft subcombination (S2), such that the lock (12) is of the fast lock kind, where its locking face (12d) is of the click kind, being raised by the action of a spring (13) also provided inside the cylinder (3), and compressed upon interference thereof with the inner wall of the intermediary shell (5), which acts in the definitive lock, when protruding and adjacent to its edge (5a).</p> |
