The utility model provides a screw lock nut, which comprises a nut body, an extension body, a nut body and an extension body, wherein a threaded hole is arranged on the side wall of the extension body, a plurality of side openings are uniformly arranged on the side wall of the extension body, and an external thread is arranged on the side wall of the extension body; the utility model also comprises a lock nut, wherein the locking nut is provided with a coaxially stepped through hole, and the stepped through hole comprises a locking screw hole and an aperture with a smaller aperture For the larger locking smooth hole, the inner wall of the locking smooth hole close to the end face is fixed with a locking ring with a cone-shaped through hole in the last week. The inner diameter of the locking ring is gradually increased from small to large along the direction of the locking smooth hole to the locking screw hole. When the screw lock nut is used, the lock nut is screwed on the extension body, and the locking ring forms extrusion pressure and tightening force on the extension body port, which forces the side port on the extension body to contract inward, so that the thread between the extension body and the screw is compressed, and the compression strengthens the friction between the threads, prevents the friction between the threads from disappearing, and achieves the purpose of locking the fastener and preventing loosening.

旋拧锁紧螺母
本技术涉及机械装备紧固件领域,特别涉及一种旋拧锁紧螺母。
技术介绍
机械装备从零件到整机的组装过程离不开紧固件的紧密配合。螺栓紧固件是应用最为广泛的一种紧固件形式,在装备运输以及运转作业等各个环节中,由于振动等外力的影响,螺栓紧固件会因为相互咬合的螺牙之间的压力瞬间消失而使得螺纹之间的摩擦力为零,从而使螺纹连接出现松动甚至脱落,从而影响装备的正常性能甚至会导致装备发生故障。因此,螺栓紧固件的防松防脱,一直是本领域从业人员亟需解决的技术问题。为了在市场竞争中利用技术优势抢占先机,针对上述问题,申请人组织技术人员进行了技术攻关,以期解决螺栓紧固件易松脱的问题。
技术实现思路
针对螺栓紧固件易松脱的技术问题,本技术提供了一种旋拧锁紧螺母,该旋拧锁紧螺母的技术方案是这样实现的:所述旋拧锁紧螺母,包括螺母本体,螺母本体一端面向外延伸形成延展体,螺母本体和延展体上同轴开设有贯通的,与螺杆相匹配的螺纹孔,延展体侧壁上沿其轴向均布有若干侧口,延展体外侧壁上设置有外螺纹;还包括锁紧螺母,锁紧螺母上设置有同轴的台阶状通孔,台阶状通孔包括孔径较小的锁紧螺孔和孔径较大的锁紧光孔,锁紧螺孔与延展体外侧壁上的外螺纹相匹配,锁紧光孔靠近端面的内壁上周向固定有开设有锥状贯通孔的锁紧圈,沿锁紧光孔指向锁紧螺孔方向,锁紧圈的内径由小逐渐变大。进一步的,所述延展体端面上开设有倒角。进一步的,所述锁紧光孔中,锁紧圈底端面距锁紧光孔底端面之间的高度大于延展体侧口的轴向长度。本旋拧锁 ...
