Abstract

The utility model discloses a locking flat washer, which belongs to a fastener and is generally arranged between a nut or a screw head and a connected part. The locking flat washer comprises a flat washer body, wherein the upper end face and the lower end face of the flat washer body are respectively provided with a plurality of frustum-shaped anti-loosening bumps. When strong vibration is applied to the nut or a screw of an anti-loosening flat washer, the nut or the screw can be better prevented from loosening.

Description

The locking plain washer
Technical field:
The utility model relates to a kind of fastening piece, specifically is a kind of locking plain washer.
Background technique:
Plain washer uses comparatively frequent in mechanical connection, and it is placed on nut or screw head usually and is connected between the part, is used to prevent that screw or nut from use becoming flexible.Upper and lower two end faces of conventional plain washer mostly are smooth plane, this smooth plane and nut, screw head and the frictional force that is connected between part are very little, when nut or screw are subjected to than strong vibration, nut or screw just are easy to take place loosening, therefore, the anti-loosing effect of above-mentioned plain washer still need improve.
The model utility content:
The technical problems to be solved in the utility model is, provides a kind of when nut or screw are subjected to than strong vibration, can prevent better that nut or screw from loosening locking plain washer taking place.
Technical solution of the present utility model is that a kind of locking plain washer with following structure is provided: comprise the plain washer body, wherein, be equipped with a plurality of locking projectioies of moving back on upper and lower two end faces of plain washer body.
Locking plain washer described in the utility model, wherein, the locking projection of moving back can be taper shape or frustoconic shape or pyramid shape or terrace with edge shape.
After adopting above structure, compared with prior art, the utility model locking plain washer has the following advantages: on the prior art plain washer, following two end faces are the smooth flat difference, the utility model plain washer body be equipped with a plurality of locking projectioies of moving back on two end faces up and down, therefore, behind nut or screw-driving, be that nut or screw head are when being pressed on the utility model locking plain washer, nut or screw and the frictional force that is connected between part will increase a plurality of locking moving back under the protruding effect, thereby it is loosening to prevent that effectively nut or screw from taking place when being subjected to than strong vibration, reaches the requirement of locking.
Description of drawings:
Fig. 1 is the stereochemical structure profile schematic representation of the utility model locking plain washer;
Fig. 2 is the structure for amplifying schematic representation of " I " among Fig. 1.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model locking plain washer is described in further detail:
As depicted in figs. 1 and 2, in this embodiment, the utility model locking plain washer comprises plain washer body 1, is equipped with a plurality of locking projectioies 2 of moving back on upper and lower two end faces of plain washer body 1, and the locking projection 2 of moving back is frustoconic shape.
The working principle of the utility model locking plain washer is: after nut (not shown) or screw (not shown) are tightened, be that nut or screw head are when being pressed on the utility model locking plain washer, nut or screw and be connected frictional force between part and will lock be provided with on upper and lower two end faces of plain washer a plurality of locking at the utility model and move back under the effect of projection 2 and increase, thereby it is loosening to prevent that effectively nut or screw from taking place when being subjected to than strong vibration, reaches the requirement of locking.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
