Description
Technical field
The present invention relates to the anti-loosening assembly of a kind of removable fasteners, belong to the screw fastener technical field.
Background technique
Screw, screw rod or bolt are used for two or more members are tightened together.During these threaded link self-lockings, the frictional force that produces on the screw thread supporting surface prevents that it is loosening.If owing to skid and pretightening force when being zero can not compress between the screw thread each other, screw just possibly produce loosening when bump or vibrations.Therefore people have adopted different anti-loosening parts in different occasions.
For example, requiring high pretension screw to connect perpendicular to bolt axis and waiting to tighten up the not hard occasion of component surface and adopt the ratchet screw nut.To use little sealed binder for crust.The compress gasket that perhaps adopts the shape of flanged pin or outer convex shoulder to match.Or use forms non-removable locking parts with solder joint or weld seam mode.
These locking parts can only be applicable to specific applications usually, and are not quick detachable, and will consider that the material of dynamic load, thermal load, screw makes its intensity that can reach, and problem such as cost.
Summary of the invention
The present invention provides a kind of comparatively general removable fasteners anti-loosening assembly in order to overcome above-mentioned deficiency.
In order to achieve the above object; The present invention provides a kind of removable fasteners anti-loosening assembly, comprises main locking body, secondary locking body, and said main locking body is cylindrical; The upper surface of cylinder has an orthohexagonal counter sink, and orthohexagonal center line is on the axis of cylinder; On the said main locking body outer circle wall locking component group is arranged; Said locking component group comprises main locking tooth, elastic arm, shifting block; Wherein a of elastic arm end is connected on the outer circle wall of main locking body, and the b of elastic arm end is connected with main locking tooth, and the head of b end is a shifting block; The shape approximation of said main locking tooth is a right-angled triangle; Said secondary locking body is a non-circular shape, and its upper surface has a circular counter sink, and the secondary locking serrate slot of circumferential distribution is arranged along the excircle of circular counter sink at the upper surface of secondary locking body; Said secondary locking serrate slot is " V " font groove, " V " word wherein on one side along vertical direction, another side is on the right side of vertical edge, the size of secondary locking serrate slot matches with main locking tooth; During installation, secondary locking body is placed in the secondary locking body groove of connecting plate, and main locking body screws off with screw, gets in the circular counter bore of secondary locking body; When screw is screwed, the engagement of main locking tooth and secondary locking serrate slot, main locking body can only secondary relatively locking body be done and is turned clockwise.
Preferably, the profile of said secondary locking body (2) is oval or square or triangle.
Preferably, said locking component group can be for one or more.
Preferably, the hypotenuse of said main locking tooth (3) profile of tooth is circular-arc, and bent to the lateral bending near the right angle.
Preferably, said elastic arm is bent shapes such as " V " type, " Qian " type.
The anti-loosening assembly of removable fasteners of the present invention comprises a main locking body and a secondary locking body; The regular hexagon counterbore of main locking body matches with the head of screw, main locking body is rotated, when screw is screwed with screw; Through the secondary locking serrate slot engagement on main locking tooth on the main locking body and the secondary locking body; Make screw to turn clockwise, promptly can only screw, played anti-loosening effect; Because flexible arm and these two structures of shifting block apply the power of pointing to center of circle direction to shifting block the main locking tooth on the main locking body is lifted, and stagger with secondary locking serrate slot, and this anti-loosening assembly and screw can be dismantled; Detachable anti-loosening assembly of the present invention also has simple, the wider advantage of applicable situation of assembling simultaneously.

Wherein 1, main locking body; 2, secondary locking body; 3, main locking tooth; 4, elastic arm; 5, shifting block; 6, secondary locking tooth; 7, regular hexagon counterbore; 8, circular counter bore; 9, screw; 10, secondary locking body groove.
Embodiment
Be depicted as the anti-loosening assembly of removable fasteners of the present invention like accompanying drawing 1, comprise connecting plate, main locking body 1, secondary locking body 2, main locking tooth 3, elastic arm 4, shifting block 5, secondary locking tooth 6, regular hexagon counterbore 7, circular counter bore 8, screw 9; Said main locking body 1 is cylindrical, and the upper surface of cylinder has an orthohexagonal counter sink 7 (seeing accompanying drawing 3), and the axis of orthohexagonal center line and cylinder coincides; On the outer circle wall of said main locking body 1, at the radial distance biggest place two locking component groups are arranged, each locking component group comprises main locking tooth 3, elastic arm 4, shifting block 5; Wherein elastic arm 4 is the U type, and its a end is connected on the outer circle wall of main locking body 1, and the b of elastic arm 4 end is connected with main locking tooth 3; The head of b end is a shifting block 5; The shape approximation of said main locking tooth 3 is a right-angled triangle, and hypotenuse is an arc, and bent to the lateral bending near the right angle; Said secondary locking body 2 is oval, and its upper surface has a circular counter sink 8, and the secondary locking serrate slot 6 of circumferential distribution is arranged along the excircle of circular counter sink 8 at the upper surface of secondary locking body 2; Said secondary locking serrate slot 6 is " V " font groove, " V " word wherein on one side along vertical direction, another side is on the right side of vertical edge, the size of secondary locking serrate slot 6 matches with main locking tooth 3.
During installation, said secondary locking body 2 is placed in the secondary locking body groove 10 of connecting plate with the mode of Spielpassung; The hex-shaped head of said screw 9 is put into the regular hexagon counterbore 7 of main locking body 1 with the mode of Spielpassung; Main locking body 1 is along with screw 9 underspins; Get in the circular counter bore 8 of secondary locking body 2; In the middle of the interior counterbore wall of the outer wall of main locking body 1 and secondary locking body 2 certain interval is arranged, be used for holding elastic arm 4; When screw 9 is screwed; In two main locking teeth 3 of main locking body 1; Have at least a meeting to be fastened in the secondary locking serrate slot 6 of secondary locking body 2, the engagement system of main locking tooth 3 and secondary locking serrate slot 6 is shown in accompanying drawing 4, and wherein arrow is the moving direction of main locking tooth 3.
When screw 9 oppositely unclamped, because the contact position of main locking tooth 3 and secondary locking tooth 6 is a vertical edge, therefore main locking tooth 3 can't produce relative displacement vertically with secondary locking tooth 6, and screw 9 can't become flexible; At this moment, by the central direction to screw, main locking tooth 3 just can stagger with secondary locking tooth 6 along with the deformation of elastic arm 4 is lifted with two shifting blocks 5, and screw 9 gets final product counterrotating and unloads.
In sum, the anti-loosening modular construction of removable fasteners of the present invention is simple, and anti-loosening performance is good, and applicable situation is wider, and installing/dismounting is very convenient.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
