Abstract
A kind of Anti-loose bolt component, including bolt (1), washer (3) and nut (4), the screw rod (1-1) that workpiece (2), washer (3), nut (4) are sequentially set in bolt (1) is external, and nut (4) centre bore is equipped with internal thread；The contact surface A of washer (3) and nut (4) is inclined-plane or curved surface and works in coordination with the corresponding surface A ' of nut (4) that the contact surface B of washer (3) and workpiece (2) is anti-skidding locking face.The utility model has the characteristics that simple in structure, processing is quick, locking effect is good；Since the zigzag protrusion on washer is continuous setting, so even if washer there are the situations of partition losses, still can retaining nut self-tightening state, prolong the service life.
Description
Technical field
The utility model is related to mechanical fasteners part technical field, specifically a kind of Anti-loose bolt component.
Background technology
In modern industry field, nuts and bolt class product is largely used to locking mechanism part.It is outstanding in many cases,
It is applied under vibrational state, we are frequently necessary to carry out periodic inspection reinforcing to the structural member locked, prevent because
The structure dislocation that nut bolt loosening belt comes.
For the above situation, in practical operation, people remove the nut bolt that fastening has been locked using various methods, such as
With super glue, electric welding, perforation second consolidation etc., but in this way again without fundamentally going to solve nut loosening displacement
Phenomenon.
Invention content
In view of the problems of the existing technology, the utility model devise it is a kind of it is simple in structure, processing is quick, locking effect
Good Anti-loose bolt component.
The utility model Anti-loose bolt component, including bolt 1, washer 3 and nut 4, workpiece 2, washer 3, nut 4 are sequentially
It is set in outside the screw rod 1-1 of bolt 1,4 centre bore of nut is equipped with internal thread；The contact surface A of washer 3 and nut 4 be inclined-plane or
It curved surface and works in coordination with the corresponding surface A ' of nut 4, the contact surface B of washer 3 and workpiece 2 is anti-skidding locking face.
The washer 3 is evenly equipped with even number groove/land on the contact surface A of nut 4, and nut 4 connects with the corresponding of washer 3
The matched projections/grooves of even number are evenly equipped on contacting surface A '.
The washer 3 is provided with continuously zigzag protrusion 3-1 on the contact surface B of workpiece 2, zigzag protrusion 3-1's
Vertex is in the same plane, and the direction of zigzag protrusion 3-1 is opposite with locking direction.
The utility model Anti-loose bolt component has the following advantages that：With simple in structure, processing is quick, locking effect is good
The features such as；When the exclusive structure of washer to tighten nut, smooth contact surfaces, washer and the coarse of workpiece of washer and nut connect
Larger stiction is generated in contacting surface, and nut is prevented to reversely rotate to loosen.Since the zigzag protrusion on washer is
Continuous setting, so even if washer there are the situations of partition losses, still can retaining nut self-tightening state, extend and use the longevity
Life.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the side view of washer；
Fig. 3 is the stereogram of washer；
Fig. 4 is the structural schematic diagram of nut；
Fig. 5 is washer and the matched structural schematic diagram of nut；
In figure, 1 is bolt, and 1-1 is screw rod, and 2 be workpiece, and 3 be washer, and 3-1 is zigzag protrusion, and 4 be nut.
Specific implementation mode
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.Such as
Shown in Fig. 1-Fig. 5, a kind of Anti-loose bolt component, including bolt 1, washer 3 and nut 4, workpiece 2, washer 3, nut 4 sequentially cover
It is located at outside the screw rod 1-1 of bolt 1,4 centre bore of nut is equipped with internal thread；The contact surface A of washer 3 and nut 4 is inclined-plane or song
It face and works in coordination with the corresponding surface A ' of nut 4, the contact surface B of washer 3 and workpiece 2 is anti-skidding locking face.
4 grooves are evenly equipped on the contact surface A of the washer 3 and nut 4, on the contact surface A ' corresponding with washer 3 of nut 4
It is evenly equipped with 4 matched protrusions.Or 2 protrusions are evenly equipped on the contact surface A of washer 3 and nut 4, nut 4 and washer 3
It is evenly equipped with 2 matched grooves on corresponding contact surface A '.Or washer 3 is provided with round and smooth song on the contact surface A of nut 4
Face is recessed, and matched curved protrusion is provided on the contact surface A ' corresponding with washer 3 of nut 4.Or washer 3 and nut 4
It is provided with round and smooth curved protrusion on contact surface A, matched curved surface is provided on the contact surface A ' corresponding with washer 3 of nut 4
Recess.
The washer 3 is provided with continuously zigzag protrusion 3-1 on the contact surface B of workpiece 2, zigzag protrusion 3-1's
Vertex is in the same plane, and the direction of zigzag protrusion 3-1 is opposite with locking direction.
The utility model is realized in this way：When tightening nut, the smooth contact surfaces of washer and nut, washer and workpiece
Stiction reversed each other is generated in rough contact surface, and the latter is more than the former；Washer is also pressed by from nut simultaneously
Power and holding power from workpiece, the two are reversed each other；To prevent nut reverse rotation from then loosening.The object fastened at this time
Body will can not be loosened or shifted by permanent locking, Anti-loose bolt component, unless nut or washer body are destroyed.
Since the zigzag protrusion on washer is continuous setting, so even if washer there are the situations of partition losses, still
The self-tightening state of energy retaining nut, prolongs the service life.
