1. An anti-theft security device for attaching to a rim of a vehicle wheel on a body in a suspension system of a vehicle, wherein the rim and the body have openings configured to receive at least one of said security device, the anti-theft security device comprising:
a fixing unit (100) configured as a bolt or nut, to which a torque is applied for tightening the wheel of the vehicle and fixing with the body in the suspension system of the vehicle, wherein said fixation unit (100) comprises:
a central screw having an elongated cylindrical body with an external thread configured to be inserted in at least one of the openings of the rim of the wheel and of the vehicle hub,
a head of a conical shape at one end of the cylindrical body of said screw, the conical head having a flat upper surface, of which, in a central part protrudes a circular projection directed upwards and on which a nut is integrally arranged,
wherein a neck is formed between the conical head and the nut;
wherein the nut has a body defining vertical walls with a hexagonal shape,
wherein the nut has a central drilling projected inward up to the flat surface of the conical head forming a circular cavity,
wherein a through drilling (103, 104) is formed in each one of the walls of the nut, the through drillings being aligned with each other, parallel to the flat surface of the conical head; and
a closing and opening mechanism (200) tightly fixable on the vertical walls of the nut, said closing and opening mechanism (200) comprises:
a hollow main casing (201) having a closed upper end and a lower end with an open peripheral edge,
wherein the lower end has a diameter smaller than a diameter of the closed upper end;
wherein the main casing (201) has a globally cylindrical shape and at least a pair of partial drillings (202) generally circular in shape in art internal part at one end thereof,
at least a pair of partial drillings (202) are arranged opposite to each other inside the inner face of the main casing (201) located in a peripheral area thereof,
wherein a central part of the main casing (201) comprises a medium drilling having a globally circular shape and having a dimension at least two orders greater than the at least a pair of partial drillings (202),
wherein the main casing (201) further comprises at least one rolling drilling (203) for receiving a rolling device (204) therein, such that the rolling device (204) is in contact with a bottom of the rolling drilling (302),
wherein the main casing (201) further comprises an indicator (250) on a flat surface thereof for showing a location or position of the fixing unit (100) when covered by the main casing (201), wherein the indicator (250) is coincident with a partial notch (102);
a core (300) received within the main casing, said core (300) comprising:
a core head (301) defining a circular body having an upper surface with a partial drilling (302) in a central part thereof, wherein said partial drilling (302) is configured to receive a primary spring (303); as well as a core extension (318) defined by a body of cylindrical cross section defining in a central part and in coincidence with an axial axis, a partial drilling (308);
wherein the core head (301) comprises at least a pair of globally circular partial openings (304) coincident with the at least a pair of partial drillings (202) of the main casing (201) and a rolling drilling (305) defined by a generally cylindrical drilling-type cavity, wherein a core rolling device (317) with globally spherical shape is inserted into the rolling drilling (305) up to the equatorial zone of the core rolling device (317);
wherein the core head (301) further comprises a connection extension (306) having a body of globally cylindrical shape with a threaded rib (307 in a periphery thereof for inserting and coupling the connection extension (306) into/with the core extension (318);
wherein the core extension (318) has a threaded rib (309) in an interior thereof that connects with the threaded rib (307) of the core head,
wherein the core extension (318) has in a periphery thereof an external diameter reductor formed by a flat surface (310) allowing insertion in a guiding extrusion (105) drilling of a partial drilling (106) located in the fixing unit (100), wherein said insertion is also assisted by a chamfered edge (311) at one end of the core extension (318); and
wherein the core extension (318) comprises a drilling (312) arranged perpendicular to an axial axis of the core extension (318) proximal to the end in which the partial drilling (302) is located, wherein the combination drilling (312) has a preferably circular cross-section, wherein a first latch (313) and a second latch (316) are received therein, wherein the first latch (313) comprises two portions, the first portion being a retention extension (314) comprising a body of generally cylindrical shape having at an end thereof a receiving extension (315) of greater diameter than the retention extension (314) and having in an interior thereof a partial hollow cavity, wherein the second latch (316) having a generally cylindrical shape and of a smaller diameter than the partial hollow cavity is received in said partial hollow cavity,
wherein the first and second latches (313, 316) are retained within the combination drilling (312) by a core biasing means (319) having a body of preferably circular cross section and having two different thread pitches between the helixes forming it, wherein a thread pitch for the core biasing means portion (319) that is closest to the core head (301) is greater than a thread pitch in contact with the lateral sides of the first and second latches (313, 316) within the combination drilling (312), such as to prevent the first latch (313) and the second latch (316) from leaving the combination drilling (312) and its eventual mispositioning within the arrangement;
wherein the rolling device (304) can contact the core rolling device (317) by turning the main casing (201).
