Locking Mechanism

A locking mechanism comprising:

• a main cylinder (2);
• a fixed base (3);
• pairs of articulated arms (4) equipped with rods holders (4.1);
• wherein the main cylinder (2) has a cylindrical partially tubular body having an end suitable for receiving a core lock (2.1), an end of the main cylinder (2) located opposite to the end suitable for receiving the core lock having a slot diametrically disposed forming two solid semicircular walls (2.2), each semicircular wall (2.2) having a latitudinal passing hole (2.3);
• the latitudinal passing holes (2.3) being aligned;
• the fixed base (3) being a monobloc body provided with a centrally disposed hole (3.1) of circular contour, one face of the fixed base (3) having two articulation tabs (3.2) arranged spaced apart and aligned by the centrally disposed hole (3.1);
• each articulation tab being formed by two parallel walls (3.3) spaced apart by a gap, each parallel wall (3.3) incorporating a latitudinal passing hole (3.4);
• the latitudinal passing holes (3.4) of one articulation tab being aligned to each other;
• wherein the pairs of articulated arms (4) comprise bodies with an “L” shaped profile, each articulated arm (4) having a horizontal extension followed by a vertical portion;
• each articulated arm (4) having three through holes (4.2, 4.3, 4.4);
• a first through hole (4.2) being oblong and shaped at one end of the articulated arm (4), a second through hole (4.3) being circular and arranged at the other end of the articulated arm (4), and a third through hole (4.4) being circular and arranged at a center, in a region where a 90° curve defines the “L” shaped profile of the articulated arm (4);
• the first through holes (4.2) of the articulated arms (4) receiving rods holders (4.1).
