Description
Technical field
The invention belongs to technical field of fastening, specifically a kind of self-locking screw.
Background technology
The fastener of screw bolt and nut composition is widely used in the company of the parts in the engineering goods such as lathe, automobile, agricultural machinery
It connects, standard thread causes connected parts because its intrinsic defect often voluntarily loosens under conditions of violent vibration
Loosening, gently then cause the function of machinery equipment to be lost, it is heavy then even lead to safety accident.Existing solution threaded fastener loosens
Method be mainly the following：Nylon or elastic collet are inlayed, retaining pin is installed, installs retaining cushion etc. additional.The above method
Generally existing anti-loosing effect is poor, manufacture or assembly technology are complicated, use cost is high and the defect of reusability difference.
Patent document 1：A kind of self-locking screw, application number：2009202812342
Patent document 2：A kind of pull-type self-locking screw, application number：2011204573413
In above patent document 1, by the way that tapered ramp is arranged in externally threaded tooth bottom, internal thread is in its screwing length
Each cusp uniformly press closer on the tapered ramp of outer thread bottom, to generate the normal direction more much bigger than standard thread
The frictional force also naturally considerably increased between internal and external screw thread is significantly greatly increased in power, normal force, and being reached with this prevents connection screw thread
The purpose of loosening；Invention consideration is too unilateral, does not account for difficulty when bolt is screwed into workpiece, which makes bolt twist
Difficulty when entering workpiece increases so that bolt abrasion between the two when entering workpiece becomes larger, and is being ground into the bolt in workpiece
It possibly can not be pressed closer on the tapered ramp of outer thread bottom in the case of damage, anti-loose effect can not be played.
In above patent document 2, by the way that the bolt that another nut is circular cone is arranged in stud base, pass through circular cone
So that the screw rod bottom dilatating and deformable of bolt, to play anti-loose effect；After playing anti-loose effect, bolt can not be torn open for the invention
It removes so that the repairerment difficulty using the equipment of the bolt increases.
