Abstract
The utility model discloses a locknut, belongs to a hardware fastener, and mainly solves the problems of the loosening and failure of nuts. The locknut comprises a nut body, wherein a thread is formed on a wall of an inner hole of the nut body; and three convex retaining sheet irons are arranged on three spaced side edges of the top surface of the nut body respectively. By the structure of embedding the retaining sheet irons into the thread, the aim of preventing the nut from being loosened is fulfilled by the joining of the retaining sheet irons and the thread by means of the stress deformation of the retaining sheet irons.
Description
Technical field
The utility model relates to a kind of hardware fastening, specifically a kind of lock nut.
Background technique
Nut is one of five metals material that is used for fasten structural elements together, and it realizes fastening function through the thread engagement with bolt, but the failure mode that nut can occur after long-term the use and bolt looseness is thrown off produces potential safety hazard.
The model utility content
The purpose of the utility model is to provide a kind of lock nut, mainly solves the problem that nut loosening lost efficacy.
The technological scheme that its technical problem of the utility model solution is taked is: a kind of lock nut; Its structure comprises nut body; Described nut body inner hole wall is provided with screw thread, and three side edge that described nut body is separated by at its end face respectively are provided with the stopping iron plate of a convexity.
The beneficial effect of the utility model is: adopt the stopping iron plate to embed the structure of screw thread, by the stress deformation of stopping iron plate, the interlock realization through stopping iron plate and screw thread prevents the purpose that nut gets loose.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the user mode figure of the utility model.
Among the figure: 1 stopping iron plate, 2 screw threads, 3 nut bodies, 4 bolts.
Embodiment
As shown in the figure.A kind of lock nut, its structure comprises nut body 3, and described nut body 3 inner hole walls are provided with screw thread 2, and three side edge that described nut body 3 is separated by at its end face respectively are provided with the stopping iron plate 1 of a convexity; The length of said stopping iron plate 1 is slightly larger than the distance of the side of nut 3 to screw thread 2 places.
During use, nut 3 and bolt 4 is fastening, by instrument stopping iron plate 1 to be pounded down to nut 3 central directions then, the stopping iron plate 1 of distortion can withstand on the screw thread 2 of bolt 4.When nut 3 was loosening, the screw thread 2 that stopping iron plate 1 is withstood produced the trend of turn downwards gradually like this, but the stopping iron plate 1 after the distortion can be locked together in screw thread 2, reached the purpose that prevents that nut 3 from getting loose.
