Shown in the accompanying drawing 1a, an end of shank of bolt (1) right-handed thread have one with axis of spindle intersect less than 90 the degree inclined-plane (F1); Locking head shown in the accompanying drawing 1b (2) be one section with outside The spiro column of screw thread, one end has two inclined-planes that intersect with shaft centre line, the inclined-plane (F1) of first inclined-plane (F1) and shank of bolt (1) is identical and screw thread is continuous, second inclined-plane (F2) is in the counter clockwise direction of first inclined-plane (F1), and the intersection of two inclined-planes (F1), (F2) departs from the shaft centre line of locking head (2); When dextrorotation turn nut (3), because the inclined-plane (F1) of first inclined-plane (F1) of locking head (2) and shank of bolt (1) coincide and screw thread is continuous, then smoothly precession.
Because shank of bolt (1), the axial dimension on locking head (2) inclined-plane (F1), axial dimension less than nut (3), nut (3) is being vibrated or the counter clockwise direction moment of face, when being rotated counterclockwise, frictional force drives locking head (2) and is rotated counterclockwise, nut shown in the accompanying drawing 1c (3) rotates along shaft centre line, locking head (2) is along first inclined-plane (F1) the intersection rotation with second inclined-plane (F2), locking head (2) produces a tangential force to nut (3), stop the continuation dextrad rotation of nut (3), reached anti-loosening purpose.
When needing artificially remove to connect, can on how much flower types of the protruding or spill of locking head (2), apply the clockwise direction moment of face, left-handed nut (3) then can screw out smoothly simultaneously.
Bolt shank shown in the accompanying drawing 2a (1), have the arc-plane (F0) of (or two a) vertical axis and one and axis (center line) to intersect inclined-plane (F1) less than 90 degree at a threaded end, this inclined-plane (F1) cut by the string perpendicular to axis plane (F0).
Locking head (2) shown in the accompanying drawing 2b also has the fan-shaped plan (F0) of (or two a) vertical axis.Also have two inclined-planes with axes intersect, first inclined-plane (F1) is identical with the inclined-plane (F1) of bolt shank (1), and continuous with the screw thread of bolt shank (1).Second inclined-plane (F2) is in the counter clockwise direction on first inclined-plane, and the intersection of two inclined-planes (F1), (F2) departs from locking shaft centre line.
The plane (F0) of bolt shank (1) coincide with the fan-shaped plan (F0) of locking head (2), when dextrorotation turn nut (3), and unlikely endwisely slipping, precession smoothly.
The female thread portion of the nut shown in the accompanying drawing 3b (3) has the fan groove (C3) of an interior angle (F3), and interior angle (F3) is less than 180 degree; Recessed locking tongue (4) is the inequilateral fan-shaped cylinder of an interior angle (F4), the identical screw cutting in the big limit of fan-shaped big limit of recessed locking tongue (4) shown in the accompanying drawing 3c and nut (3) fan groove (C3) is continuous, and the interior angle (F3) of nut (3) fan groove (C3) is greater than recessed locking tongue (4) interior angle (F4); Recessed locking tongue (4) places within the fan groove (C3) of nut (3);
The axial dimension of nut (3) fan groove (C3) is less than the axial dimension of nut (3).
The threaded end of bolt shank shown in the accompanying drawing 4a (1) has the fan groove (C1) of an interior angle (F6), and interior angle (F6) is equal to or less than 180 degree; Protruding locking tongue (5) shown in the accompanying drawing 4c is the inequilateral fan-shaped cylinder of an interior angle (F5), the big limit of fan-shaped big limit of protruding locking tongue (5) and bolt shank (1) fan groove (C1) is identical and screw thread is continuous, and the interior angle (F6) of bolt shank (1) fan groove (C1) is greater than protruding locking tongue (5) interior angle (F5); Protruding locking tongue (5) places within the fan groove (C1) of bolt shank (1);
Nut (3) is being vibrated or the counter clockwise direction moment of face, when being rotated counterclockwise, frictional force drives protruding locking tongue (5) and is rotated counterclockwise, nut (3) rotates along shaft centre line, protruding locking head (5) is along the intersection rotation of fan-shaped interior angle, the big limit of protruding locking head (5) produces a tangential force to nut (3), stops the continuation dextrad rotation of nut (3), has reached anti-loosening purpose.
Because the axial dimension of bolt shank (1) fan groove (C1) less than the axial dimension of nut (3), then can not get loose artificially once connect, and is applicable to bolt for riveting.
