Spring is connected;One side of the tightening nut is provided with spring detent, and spring detent fixes clamping with screw rod.
As further program of the utility model:Clamping thing is installed between the bolt head and nut.
As further program of the utility model:The spring detent is detachable.
As further program of the utility model:The integration of the self-locking bolt, nut, tightening nut and self-tightening spring
Connection.
Compared with prior art, the utility model beneficial effect:
This elastic card pin check bolt is by setting nut, tightening nut, self-tightening spring and spring detent, self-tightening spring
It is arranged between nut and bolt head by compression, subjects the effect of elastic force, can be by certainly when equipment vibrations produce gap
Tight moment of torsion is compensated, and clamping torque can be maintained not diminish, therefore more suitable for bearing the anti-of vibratory shock load thread connection
Pine;Spring detent is detachable, can unload tightening nut, completes dismounting, and locking relative to permanent, self-tightening type check bolt can be torn open
Unload, reinstall and be easy to maintenance of equipment and member replacing, the integration connection of self-locking bolt, nut, tightening nut and self-tightening spring,
So that overall structure is more fastened.
