Abstract

The utility model relates to a lock washer, which comprises a washer body, wherein a counter bore and a through hole are arranged on the center of the upper surface of the washer body, the counter bore is of a hexagon, and a plurality of lock stripes which are distributed along the circumferential direction of the washer body are arranged on the lower surface of the washer body. Therefore, a screw head or a nut can be embedded in the counter bore, thereby enabling the washer body and the screw or the nut to rotate together. When the nut or the screw is screwed, the frictional force between the nut or the screw and connected parts can increase under the action of a plurality of lock stripes, the nut or the screw is prevented from loosing in special environment such as under strong vibration, and the locking requirements are achieved.

Description

A kind of lock washer
Technical field
The utility model relates to a kind of lock washer, specifically a kind of lock washer that can prevent that screw or bolt from getting loose under particular surroundings.
Background technique
Packing ring is conventionally placed on nut or screw head and is connected between part, upper surface and the lower surface of general packing ring are smooth flat, therefore packing ring and nut, screw head and the frictional force that is connected between part are very little, when nut or screw are in particular surroundings, for example, while being subject to compared with strong vibration, nut or screw are just easily loosening, cause potential safety hazard.
Model utility content
The utility model object is that a kind of lock washer that can prevent that screw or bolt from getting loose under particular surroundings is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of lock washer, comprise packing ring body, and the center of the upper surface of described packing ring body is provided with counter sink and through hole; Described counter sink is Hexagon; On the lower surface of described packing ring body, be provided with the locking striped of a plurality of circumferential distributions along packing ring body.
Preferably, described a plurality of locking striped is uniformly distributed around packing ring body for one week.
Preferably, described a plurality of locking striped distributes in the shape of a spiral; The Hand of spiral of described locking striped is identical with the screw-in direction of screw.
Preferably, the sectional shape of described locking striped is triangular in shape.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The lock washer of the utility model scheme, the counter sink of the upper surface of packing ring body is Hexagon, screw head or nut can be embedded wherein, packing ring body and screw or nut are together rotated, therefore, after nut or screw screw, nut or screw and the frictional force being connected between part will increase under the effect of a plurality of locking stripeds, thereby effectively avoid nut or screw in particular surroundings, for example, while being subject to compared with strong vibration, occur to become flexible, reach the requirement of locking.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The stereogram that accompanying drawing 1 is a kind of lock washer described in the utility model;
The other direction stereogram that accompanying drawing 2 is a kind of lock washer described in the utility model;
The sectional view of the locking striped that accompanying drawing 3 is a kind of lock washer described in the utility model;
Wherein: 1, packing ring body; 2, counter sink; 3, through hole; 4, locking striped.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1-2 is a kind of lock washer described in the utility model, comprises packing ring body 1, and the center of the upper surface of described packing ring body 1 is provided with counter sink 2 and through hole 3; Described counter sink 2 is Hexagon; On the lower surface of described packing ring body 1, be provided with the locking striped 4 of a plurality of circumferential distributions along packing ring body 1; Described a plurality of locking striped 4 is uniformly distributed around packing ring body for 1 one weeks in the shape of a spiral; The Hand of spiral of described locking striped 4 is identical with the screw-in direction of screw.
As shown in Figure 3, the sectional shape of described locking striped 4 is del, the screw-in direction that in figure, the direction of arrow is screw, and triangle is longer near one side of screw threads Inbound, and triangle is shorter away from one side of screw threads Inbound.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The lock washer of the utility model scheme, the counter sink 2 of the upper surface of packing ring body 1 is Hexagon, screw head or nut can be embedded wherein, packing ring body 1 and screw or nut are together rotated, therefore, after nut or screw screw, nut or screw and the frictional force being connected between part will increase under the effect of a plurality of locking stripeds 4, thereby effectively avoid nut or screw in particular surroundings, for example, while being subject to compared with strong vibration, occur to become flexible, reach the requirement of locking.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, within all dropping on the utility model rights protection scope.
