Jewelry module in which a rigid structure with few parts is obtained

A lock assembly of a jewelry module used for joining jewelry parts to each other in earrings and bracelets type jewelry joined by methods known as chain or waterway, the lock assembly comprising:

• a module body arranged in a side-by-side arrangement without the need to form an independent lock body, which allows the entry of a lock striker on the horizontal axis (X) and at the same time allows the positioning of a movable lock on the vertical axis (Z), in order to obtain a compact structure and to hide the lock components and to obtain a rigid structure,
• a positioning area in which said movable lock is concealed,
• a lock slot formed along the x-axis of module bodies arranged side by side,
• wherein the movable lock is fixed in a positioning area by means of a bearing cavity and positioned for rotary movement,
• an axis of rotation (P), which provides the rotational movement restricted by the contact of said movable lock with a pressure surface, and
• a nail which is separated from nail slots by means of said axis of rotation (P) and in contact with the pressure surface,
• wherein the module body comprises another bearing cavity, which is centred by the bearing cavity and provides limited rotational movement for the movable lock.
