Abstract
The utility model belongs to a fastening piece, particularly a self-locking nut which is composed of a nut main body 4, a cavity inside the nut main body, and screw threads. The end part of the inner cavity of the self-locking nut is provided with a trumpet-shaped spring piece 2 of which the inner ring is provided with a plurality of supporting claws 6, and the bottom part of the spring piece is provided with a sliding blade 5. The spring piece 2 is spaced by a spacing ring 3 fastened in the inner cavity of the nut main body 4. The inner diameter circled by the supporting claws 6 of the spring piece 2 is smaller than the inner diameter of the screw threads of a screw bolt.
Description
The utility model belongs to a kind of fastening coupling.
The easy in use loose or dislocation of plain nut causes mechanical failure, especially in the stronger easier phenomenon that gets loose in place of vibration.Therefore, retaining anti-loose methods more commonly used break down avoiding, and common have boring back dress opening Xiao on bolt, or on bolt fluting back dress Non-return ring, or use spring washer etc.But all there is shortcomings such as making loaded down with trivial details, fragile link and use inconvenience in these methods.
The objective of the invention is to design a kind of manufacturing and retaining nut easy to use.
This nut is made of nut body 4 and inner cavity and screw thread thereof, a trumpet-shaped spring sheet 2 is arranged in the end of nut intracavity, the inner ring of this spring sheet has N support claw 6, slip sword 5 is arranged at the bottom, spring sheet 2 is spacing by the limited ring 3 that is fastened on nut body 4 inner chambers, and can be in this cavity upper and lower play with freely rotate, the N of spring sheet the interior circular diameter that support claw surrounded is slightly less than the internal diameter of bolt thread.
During use, swivel nut body to bolt 1 head end contacts with spring sheet, spring sheet contacts with limited ring, make the support claw pressurized of spring sheet and upwarp,, continue rotation with the thread engagement of bolt, spring sheet and nut body are rotated simultaneously, until the slip sword gland nut body of spring sheet bottom, at this moment, support claw has certain pressure to bolt.If when causing nut body to do opposite spin because of reasons such as vibrations, nut body will be made slide relative with spring, and support claw is increased and the realization self-locking rapidly the pressure of bolt.
During dismounting, need to use spring sheet wrench 7 as shown in Figure 3, make spring sheet and nut body do counterrotating simultaneously, just removable nut.
The utility model has the advantages that self-locking is effective, simple in structure, easy to use.
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is the plan view of spring sheet.
Fig. 3 is the structural drawing of spring sheet wrench.
