Description
Technical field
The utility model relates to mechanized equipment fastener areas, in particular to one kind screws locking nut.
Background technique
Assembling process of the mechanized equipment from part to complete machine be unable to do without the tight fit of fastener.Bolt fastener is application
Most commonly used a kind of fastener forms, in the links such as equipment transport and runs, due to external force such as vibrations
It influences, bolt fastener can make the frictional force between screw thread to be because of pressure pop-off between the thread that is mutually twisted
Zero, occur loosening to make to be threadedly coupled or even fall off, so that the normal performance for influencing equipment, which results even in equipment, occurs event
Barrier.Therefore, the technical issues of locking anticreep of bolt fastener is always this field practitioner's urgent need to resolve.
In order to be gained the initiative in market competition using technical advantage, in view of the above-mentioned problems, applicant organizational technology personnel
Research of technique is carried out, to solve the problems, such as that bolt fastener easily loosens.
Utility model content
The technical issues of easily loosening for bolt fastener, the utility model provide one kind and screw locking nut, the rotation
The technical solution for twisting locking nut is achieved in that
Described to screw locking nut, including nut body, nut body one end extends outwardly to form extension, nut sheet
Perforation is coaxially offered on body and extension, the threaded hole to match with screw rod is evenly equipped on extension body sidewall along its axial direction
Several side ports are provided with external screw thread on extension lateral wall；
Further include locking nut, be provided with coaxial step-like through-hole on locking nut, step-like through-hole include aperture compared with
The biggish locking unthreaded hole of small locking screw holes and aperture, locking screw holes match with the external screw thread on extension lateral wall, locking
Unthreaded hole is circumferentially fixed with the clamp ring for offering cone cell through hole on the inner wall of proximal end face, is directed toward locking screw holes along locking unthreaded hole
The internal diameter in direction, clamp ring is become larger by small.
Further, chamfering is offered on the extension end face.
Further, in the locking unthreaded hole, clamp ring bottom face is greater than away from the height between locking unthreaded hole bottom face to be prolonged
Open up the axial length on side mouthful.
Originally it is as follows to screw locking nut working principle: in use, first screwing nut body and extension on screw rod
It is fastened to by fastener；After the completion of fastening, locking nut, which is screwed, makes clamp ring on locking nut in extension gradually
Extruding force and tightening force are formed close to extension and then to extension port, forces the side port on extension to contract, makes to prolong
Screw thread between Zhan Tiyu screw rod is compacted, this extruding force and tightening force, while can also be made on the outside of locking nut and extension
Screw thread on wall is compacted, and is compressed the frictional force strengthened between screw thread, is effectively prevented the disappearance of frictional force between screw thread,
The anti-loose purpose of locking of fastener is just reached accordingly.
Detailed description of the invention
The attached drawing for constituting a part of the utility model is used to provide a further understanding of the present invention, this is practical new

Specific embodiment
It should be noted that in the absence of conflict, the feature in the embodiments of the present invention and embodiment can
To be combined with each other.
The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
It is described in the utility model to screw locking nut, as shown in Figures 1 to 3, including nut body 1,1 one end of nut body
It extends outwardly to form extension 2, coaxially offers perforation on nut body 1 and extension 2, the screw thread to match with screw rod
Hole is evenly equipped with several side ports 7 along its axial direction on 2 side wall of extension, is provided with external screw thread on 2 lateral wall of extension；
Further include locking nut 3, coaxial step-like through-hole is provided on locking nut 3, step-like through-hole includes aperture
The biggish locking unthreaded hole 5 of lesser locking screw holes 4 and aperture, locking screw holes 4 and the external screw thread phase on 2 lateral wall of extension
Match, locking unthreaded hole 5 is circumferentially fixed with the clamp ring 6 for offering cone cell through hole on the inner wall of proximal end face, refers to along locking unthreaded hole 5
To 4 direction of locking screw holes, the internal diameter of clamp ring 8 is become larger by small.
Originally it is as follows to screw locking nut working principle: in use, first screwing nut body 1 and extension 2 in screw rod
On fastened to by fastener；After the completion of fastening, locking nut 3 is screwed to the locking made on locking nut 3 in extension 2
Circle 6 moves closer to extension 2 and then forms extruding force and tightening force to 2 port of extension, force side port 7 on extension 2 to
Contract is compacted the screw thread between extension 2 and screw rod, this extruding force and tightening force, while can also make locking nut 3
It is compacted with the screw thread on 2 lateral wall of extension, compresses the frictional force strengthened between screw thread, effectively prevent rubbing between screw thread
The disappearance for wiping power, has also just reached the anti-loose purpose of locking of fastener accordingly.
It should be pointed out that the side port 7 on extension 2, which is locked, encloses 6 extruding in originally screwing locking nut use process
Shi Huixiang contract, in order to Reusability, after extension 2 are left in clamp ring 6, the side port 7 on extension 2 also needs to restore
Original state, therefore, extension need to be made of the good material of elasticity.
Originally locking nut is screwed, offers chamfering 8 on 2 end face of extension, convenient between clamp ring 6 and extension 2
Interaction.
When locking, the clamp ring 6 on locking nut 3 is oppressed 2 port of extension and is mutually squeezed with 2 port lateral wall of extension
Pressure, the screw thread that may cause on 2 port lateral wall of extension are impaired.Originally locking nut is screwed, in the locking unthreaded hole 5, locking
Enclose the axial length that 6 bottom faces are greater than 2 side port 7 of extension away from the height between locking 5 bottom face of unthreaded hole, locking described here
Enclose the end face in 6 bottom faces i.e. 8 cone cell through hole of clamp ring where internal diameter maximum.Such design is no longer needed to locking screw holes 4
It screws to 2 port of extension, clamp ring 6 can be made to be detached from extension 2.In Reusability, even if 2 port lateral wall of extension
On screw thread it is impaired, so that clamp ring 6 is detached from extension 2.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
