Abstract
A spring washer belongs to a fastener, is generally placed between a bolt head or a nut and a connected part, is mainly used for preventing a bolt or the nut from being loosened during usage and comprises a spring washer body. A plurality of anti-loosening bumps are uniformly arranged on upper and lower end surfaces of the spring washer body. When the bolt or the nut is vibrated more violently, the spring washer can perfectly prevent the nut or the bolt from being loosened.
Description
Technical field:
The utility model relates to a kind of fastening piece, specifically is a kind of spring washer.
Background technique:
We know that spring washer is placed on bolt head or nut usually and is connected between the part, are mainly used to prevent that bolt or nut from use becoming flexible.Though existing spring washer has certain locking effect, but, because upper and lower two end faces of spring washer mostly are smooth plane, this smooth plane and bolt head, nut and the frictional force that is connected between part are very little, when bolt or nut are subjected to than strong vibration, bolt or nut still can become flexible, and therefore, the anti-loosing effect of above-mentioned spring washer still need improve.
The model utility content:
The technical problems to be solved in the utility model is, provides a kind of when bolt or nut are subjected to than strong vibration, can prevent better that nut or bolt from loosening spring washer taking place.
Technical solution of the present utility model is that a kind of spring washer with following structure is provided: comprise the spring washer body, wherein, be equipped with a plurality of locking projectioies of moving back on upper and lower two end faces of spring washer body.
Spring 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 spring washer has the following advantages: on the prior art spring washer, following two end faces are the smooth flat difference, the utility model is equipped with a plurality of locking projectioies of moving back on two end faces up and down the spring washer body, therefore, after nut or bolt are tightened, be that nut or bolt head are when being pressed on the utility model spring washer, nut or bolt 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 bolt from taking place when being subjected to than strong vibration, reaches desirable locking effect.
Description of drawings:
Fig. 1 is the stereochemical structure profile schematic representation of the utility model spring washer.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model spring washer is described in further detail:
As shown in Figure 1, in this embodiment, the utility model spring washer comprises spring washer body 1, is equipped with a plurality of locking projectioies 2 of moving back on upper and lower two end faces of spring washer body 1, and the locking projection 2 of moving back is terrace with edge shape.
The working principle of the utility model spring washer is: after nut (not shown) or bolt (not shown) are tightened, be that nut or bolt head are when being pressed on the utility model spring washer, nut or bolt and the frictional force that is connected between the part (not shown) will increase a plurality of locking the moving back under projection 2 the effect that is provided with on upper and lower two end faces of the utility model spring washer, thereby it is loosening to prevent that effectively nut or bolt from taking place when being subjected to than strong vibration, reaches desirable locking requirement.
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.
