Description
Technical field
A kind of screw thread locking structure of the utility model.
Background technique
The fastening bolt self-locking effect industrially used at present is not satisfactory, is easy to pine in vibration environment use process
De-, the violent bolt of equipment vibration, nut loosen more common such as in railway, bridge, aviation field, there is very big safety
Hidden danger.
Utility model content
The utility model solves the deficiencies in the prior art and provides that a kind of structure is simple, prevents bolt violent vibration environment
The middle screw thread locking structure loosened that circles round.
To achieve the goals above, the utility model adopts the following technical solution:
A kind of screw thread locking structure, including being equipped with externally threaded screw rod and setting internal thread spiral shell with what screw rod matched
Mother, the screw rod it is outside thread recessed it is interior, multiple lock grooves, the tail of the nut are laid with along outside thread recessed extending direction
End face is equipped at least one first groove being connected to nut inner wall, is fixed in first groove convex along internal screw thread
It rises, screw out the elastic component that direction extends along nut, one end of the elastic component is installed in first groove, and the other end is in bullet
Property part elastic reaction under from the inner wall of nut stretch out first groove, when nut spinning enters screw rod, the elastic component
The first groove is retracted under the extruding of external thread of screw groove, when nut screws out screw rod, the elastic component stretches out nut inner wall
One end is installed on nut locking in lock groove.The elastic deformation that above structure utilizes elastic component to have, in nut tightening, bullet
Property part it is outside thread recessed it is interior be extruded, be retracted in it in the first groove, to not influence screwing for nut, and fasten it
Afterwards, under vibration or external force, when nut is screwed out to the position for having lock groove, the end of elastic component is pressed against in lock groove,
So that nut can not screw out, circle round under the conditions of vibration the technical problem loosened this addresses the problem plain bolt nut.
Further, the lock groove is locking surface screwing out direction side along nut, and the other side is sliding surface, the lock
Only face is radially laid along screw rod, and the locking surface and sliding surface angle are not more than 90 degree.When the locking surface and sliding of lock groove
When face meets above-mentioned condition, nut can only be screwed, and cannot be screwed out, and the angle of certain the application locking surface and sliding surface can also be big
In 90 degree, by adjusting the angle of the two, can achieve when nut screws out, the locking surface of elastic component and lock groove has one
Situations such as resistance, this resistance can prevent vibration nut loosens, but under artificial external force or can screw out, this
The present apparatus may be reused in sample.
Further, the screw rod is laid at least one lock groove in each circle is outside thread recessed.
Further, the screw rod is laid with multiple lock grooves on nut lock position.
Further, the elastic component is spring steel.It may be flexible steel or stainless steel etc..
Further, the elastic component is " 7 " font, is equipped in the first groove on the nut for fixing elastic component
Locating slot, one end of the elastic component is tightly fixed in locating slot, and the other end is stretched out from the inner wall of nut.
Further, the locating slot is triangle or linear type, the elastic component be inserted into one end in locating slot with
Positioning groove shape matches.In this way, elastic component can product be sold as a whole with nut, can also be used as
One attachment is separately sold with nut, as soon as sell as attachment, elastic component is fixed on nut when needing locking
In locating slot, when not needing, nut is just directly used.
As a kind of another structure type of screw thread locking structure, including it is equipped with externally threaded screw rod and is equipped with and spiral shell
The matched gasket of bar, the screw rod it is outside thread recessed it is interior, multiple lock grooves, institute are laid with along outside thread recessed extending direction
The external screw thread of the inner ring and screw rod of stating gasket matches so that gasket can spinning on screw rod, set on the inner ring wall of the gasket
There is at least one second groove and be arranged in the second groove and screws out the ratchet with elasticity that direction extends, the ratchet along gasket
End in the initial state from the inner ring wall of gasket stretch out, when gasket spinning enters screw rod, the ratchet is recessed in external screw thread
It is retracted under the extruding of slot in the second groove, when gasket screws out screw rod, the ratchet stretches out gasket inner wall one end and is installed on locking
By gasket locking in slot.In this way, so as to being carried out in the form of plain nut is in conjunction with present apparatus gasket
Locking, naturally it is also possible to be used to gasket other need the case where locking, so that application range is wider, and uses this knot
The gasket of structure is easily manufactured, can directly be stamped to form, therefore cost is lower.
Further, the gasket is equipped with the locating piece being conveniently fixed on other workpiece.
In conclusion the utility model utilizes the cooperation of elastic component and lock groove, nut can effectively prevent in strenuous vibration
Convolution loosens in environment, and the utility model structure is simple, processing and manufacturing is at low cost, self-locking effect is good, has biggish using city
Field and bright prospects.
