Abstract
The embodiment of the utility model discloses a combined nut device, which comprises a nut and a washer, wherein an end face of the washer is provided with a locking concave conical surface; an end surface of the nut is provided with a locking convex conical surface corresponding to the locking concave conical surface; and the nut is provided with slots extending from the locking convex conical surface to the middle of the nut. When the combined nut device is used, first a bolt (or screw) is passed through a workpiece, then the washer is sleeved on the bolt (or screw), and finally the nut is rotated on the bolt (or screw) until the nut no longer rotates, thereby achieving the installation of the combined nut device. When the nut is screwed tightly, limited by the washer, the slotted sections gradually reduce, thus changing the nominal diameter of the nut; when playing the fastening role, the nut also acts to lock the bolt, thus effectively preventing the nut and the bolt from getting loose and falling off, so that moving parts can operate safely in high-speed rotation, vibration and long-term storage rotation state. The utility model also discloses a fastener with the combined nut device.
