Abstract
The utility model discloses a kind of novel high-performance locknut, including bolt, mother nut, locking nut, the mother nut and bolt, it is connected through a screw thread respectively between locking nut and mother nut, the mother nut is by preceding g. slice header, mid-section threads connecting portion and endpiece variant part composition, the mid-section threads connecting portion is provided with mother nut external screw thread, the mother nut external screw thread is engaged with the screw thread of the locking nut, the mother nut external screw thread is deformation screw thread, the technical solution of the utility model is when product repeatedly uses, can on macroscopic examination mother nut external screw thread degree of impairment to change in time；In the threaded connection of mother nut external screw thread and locking nut, the deformation screw thread of mother nut is more firm compared to the screw thread of locking nut, generally only need to change locking nut, without changing mother nut, has more preferably superiority in economy；Deformation thread surface, which scribbles damping coatings, can effectively lift the vibration resistance of locking nut, avoid locking nut from releasing.
Description
Technical field
A kind of anti-loose fastening device is the utility model is related to, more particularly to a kind of secondary retaining mechanism has high resistance to shock
New anti-loose fastener.
Background technology
In the patent document that application publication number is CN106351936A, a kind of locking fastening dress of axial compression formula is disclosed
Put, to improve the needs of product anti-loosening property, adaptation high standard high safety and other complex environment operating modes, the axial compression formula is prevented
Loose fastener includes bolt, mother nut, locking nut, and mother nut is deformed by preceding g. slice header, mid-section threads connecting portion and endpiece
Portion forms, and the endpiece variant part of mother nut combines provided with groove, and groove combination includes upper groove and low groove, and upper groove includes straight
Line segment groove, ball recess and arc groove；Low groove includes straightway groove and hemispherical groove；The interior spiral shell of locking nut
Line is arranged to deform fine thread, and tail end end face is provided with the seal face to be fitted with the endpiece variant part of mother nut.The technology
Involved deformation screw thread is arranged among the inner ring screw thread pair of locking nut in scheme, and this design can be realized preferably
Locking nut anti-loosening property, but there is also process it is constant, type inclined-plane is carved in the case of being used for multiple times in the tooth bottom of locking nut
Degree of impairment it is not directly perceived, check it is more inconvenient；In addition, this scheme causes the damping anticreep poor-performing of locking nut, deposit
In the de- phenomenon that may shake.
The content of the invention
The utility model overcomes deficiency of the prior art, there is provided a kind of novel high-performance locknut.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：A kind of new high property
Energy locknut, including bolt, mother nut, locking nut, between the mother nut and bolt, locking nut and mother nut
It is connected through a screw thread respectively, the mother nut is made up of preceding g. slice header, mid-section threads connecting portion and endpiece variant part, the stage casing
Threaded joints are provided with mother nut external screw thread, and the mother nut external screw thread is engaged with the screw thread of the locking nut, the master
Nut external screw thread is deformation screw thread.
Preferably, the tooth bottom of the deformation screw thread is provided with tapered ramp.
Preferably, the angle between the tapered ramp and the axis of mother nut is 25~65 °.
Preferably, the angle between the tapered ramp and the axis of mother nut is 45 °.
Preferably, the deformation thread surface scribbles damping coatings.
Compared with prior art, the utility model has the advantages that：When product repeatedly uses, can intuitively check
Externally threaded degree of impairment on mother nut, to change in time；It is main in the threaded connection of mother nut external screw thread and locking nut
The externally threaded deformation screw thread of nut is more firm compared to the screw thread of locking nut, when generally occurring within replacing, only need to change locking screw
Mother, without changing mother nut, there is more preferably superiority in economy；Deformation thread surface, which scribbles damping coatings, effectively to be lifted
The vibration resistance of locking nut, avoids locking nut from releasing.
Brief description of the drawings
Fig. 1 is the mother nut structure sectional view of the utility model embodiment.
Fig. 2 is the locking nut structure schematic diagram of the utility model embodiment.
Fig. 3 is I portions partial enlarged drawing in Fig. 1.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As shown in FIG. 1 to 3, a kind of novel high-performance locknut, including bolt, mother nut 1, locking nut 2,
It is connected through a screw thread respectively between the mother nut 1 and bolt, locking nut 2 and mother nut 1, the mother nut 1 is by preceding paragraph header
Portion, mid-section threads connecting portion and endpiece variant part composition, the mid-section threads connecting portion is provided with mother nut external screw thread 101, described
Mother nut external screw thread 101 is engaged with the screw thread of the locking nut, and the mother nut external screw thread 101 is deformation screw thread, described
The tooth bottom of deformation screw thread is provided with tapered ramp 1011, and the angle between the axis of the tapered ramp 1011 and mother nut 1 is
45 °, the deformation thread surface scribbles damping coatings 1012, and the damping coatings are 3109 damping-constraining coatings.
The utility model can intuitively check the damage feelings of mother nut external screw thread 101 when product repeatedly uses
Condition, to change in time；In the threaded connection of mother nut external screw thread 101 and locking nut, the deformation of mother nut external screw thread 101
Screw thread is more firm compared to the screw thread of locking nut, when generally occurring within replacing, only locking nut 2 need to be changed, without more change owner
Nut 1, there is more preferably superiority in economy；Deformation thread surface, which scribbles damping coatings 1012, can effectively lift locking nut
Vibration resistance, locking nut 2 is avoided to release.
