Abstract
The utility model relates to a locknut subassembly, including fastening nut and lock nut, its characterized in that: fastening nut one end is cylindrical other end and is outer frustum shape, outer frustum shape bottom area is less than cylindrically, and cylindrical and outer toper contact one end are equipped with the ring plane, lock nut one end be equipped with fastening nut matched with interior frustum shape hole, be equipped with the expansion tank on the outer frustum shape, the expansion tank sets up along fastening nut's screw axial, lock nut is last to be served and is equipped with a plurality of lugs in the toper platform, be equipped with on fastening nut's the ring plane with lug complex recess, interference fit between lug and the recess. The utility model provides a locknut subassembly, the setting through the inflation groove is conducted the extrusion between the nut to the screw rod, has increased the fastening dynamics, and interference fit makes locking effect better between lug and the recess simultaneously, and this simple structure.
Description
Technical Field
The utility model relates to a fastener technical field, concretely relates to locknut subassembly.
Background
At present, the self-locking anti-loose nut with an embedded nylon sleeve or a metal sheet is generally adopted for nut anti-loose, but the loosening effect is not ideal, and the nut still has the phenomenon of falling in some high-strength mechanical equipment.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose: in order to overcome the defects existing in the prior art, the utility model provides a loosening nut component.
The utility model discloses a realize above-mentioned purpose and the technical scheme who takes does: a locknut assembly, includes fastening nut and lock nut, its characterized in that: fastening nut one end is cylindrical other end and is outer frustum shape, outer frustum shape bottom area is less than cylindrically, and cylindrical and outer toper contact one end are equipped with the ring plane, lock nut one end be equipped with fastening nut matched with interior frustum shape hole, be equipped with the expansion tank on the outer frustum shape, the expansion tank sets up along fastening nut's screw axial, lock nut is last to be served and is equipped with a plurality of lugs in the toper platform, be equipped with on fastening nut's the ring plane with lug complex recess, interference fit between lug and the recess.
Adopt above-mentioned technical scheme, at the in-process cone frustum shape hole of fastening lock nut and fastening nut's outer cone frustum shape formation extrusion, the extruded in-process expansion tank dwindles gradually, and the internal thread on fastening nut's the outer cone frustum shape can tightly paste the external screw thread on the screw rod, increases the fastening dynamics, and lug on the lock nut and the recess interference fit on the fastening nut make and restrict each other between the two simultaneously, difficult not hard up.
As a further improvement, the loosening nut assembly further comprises an elastic metal sheet, one end of the elastic metal sheet is fixedly connected with the outer surface of the fastening nut, and the other end of the elastic metal sheet is fixedly connected with the locking nut.
By adopting the technical scheme, the locking nut and the fastening nut are connected together through the elastic metal sheet to play a role of pre-tightening, so that the two nuts are not easy to loosen and are further fastened.
As a further improvement, the locking nut and the fastening nut are provided with grooves which are positioned on the same plane, and the elastic metal sheet is embedded in the grooves. The scheme can also be that the locking nut and the fastening nut are both provided with clamping grooves, and the two ends of the elastic metal sheet are provided with clamping parts matched with the clamping grooves.
Adopt above-mentioned technical scheme, the gomphosis of elastic metal piece can produce an interaction power when fastening nut takes place not hard up and make its difficult emergence not hard up in the recess, and also can produce interaction power when taking place deformation for the elastic metal piece atress, and locking effect is better, should connect to construct simply reasonable in design.
As a further improvement, the number of the lugs is 4, and the 4 lugs are arranged at equal intervals.
By adopting the technical scheme, the stress on each part between the two nuts is uniform, and the threads on the nuts and the screw rods are not easy to damage.
