Description

Technical Field

[0001] The utility model relates to the technical field of hexagonal flange nuts, in particular to a hexagonal flange nut that avoids loosening and falling off. Background Technique

[0002] Setting anti-slip teeth on the nut can improve the anti-slip ability of the hexagonal flange nut. The existing hexagonal flange nut has poor anti-loosening ability and is prone to loosening when encountering vibration. In order to avoid loosening and falling off, a locking structure is set on the hexagonal flange nut;

[0003] For example, the Chinese utility model patent with the authorization announcement number CN216922801U discloses an inlaid hexagonal flange surface anti-loosening nut, which relates to the technical field of anti-loosening nuts. The utility model includes a nut body, a locking bolt and a movable card. The bottom of the nut body is fixedly connected with a hexagonal flange. The locking bolt penetrates through the hexagonal flange. There is a notch at the bottom of the hexagonal flange. An active card is elastically connected in the notch through a torsion spring. The end of the active card is stuck on the locking bolt. A circular groove is opened at the bottom of the hexagonal flange outside the notch. By penetrating the locking bolt through the hexagonal flange and arranging a torsion spring and a movable card at the bottom of the hexagonal flange, when the limit card slot on the locking bolt rotates to the clamping part at the end of the movable card, the clamping part at the front end of the movable card can be automatically clamped into the limit card slot under the action of the torsion spring, automatically locking the locking bolt, effectively avoiding the loosening of the hexagonal flange surface nut, and improving the sealing performance of the hexagonal flange surface anti-loosening nut through a silica gel sealing ring;
