Abstract
The invention discloses a lock washer which comprises a washer body. A countersunk head hole and a through hole are formed in the center of the upper surface of the washer body. The countersunk head hole is in a hexagonal shape. A plurality of anti-loose stripes distributed in 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 into the countersunk head hole, and the washer body is made to rotate together with a screw or the nut. When the nut or the screw is tightly screwed, the friction force between the nut or the screw and a connected part can be increased under the action of the anti-loose stripes, and therefore the situation that the nut or the screw loosens in a special environment, such as the environment that the nut or the screw suffers strong vibration is effectively avoided, and the requirement of locking is met.
Description
Technical field
The present invention 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 usually is placed on nut or screw head and is connected between the 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 the particular surroundings, when for example being subject to than strong vibration, nut or screw are just easily loosening, cause potential safety hazard.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of lock washer that can prevent that screw or bolt from getting loose under particular surroundings.
Technical solution of the present invention is achieved in that a kind of lock washer, comprises the 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; Be provided with the locking striped of a plurality of circumferential distributions along the packing ring body on the lower surface of described packing ring body.
Preferably, described a plurality of locking striped evenly distributed around one week of packing ring body.
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.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
Lock washer of the present invention, 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 that is connected between part will increase under the effect of a plurality of locking stripeds, thereby effectively avoid nut or screw in being in particular surroundings, occur when for example being subject to than strong vibration to become flexible, reach the requirement of locking.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the stereogram of a kind of lock washer of the present invention;
Accompanying drawing 2 is the other direction stereogram of a kind of lock washer of the present invention;
Accompanying drawing 3 is the sectional view of the locking striped of a kind of lock washer of the present invention;
Wherein: 1, packing ring body; 2, counter sink; 3, through hole; 4, locking striped.
Embodiment
Below in conjunction with accompanying drawing the present invention is described.
Be depicted as a kind of lock washer of the present invention such as accompanying drawing 1,2, comprise packing ring body 1, 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; Be provided with the locking striped 4 of a plurality of circumferential distributions along packing ring body 1 on the lower surface of described packing ring body 1; Described a plurality of locking striped 4 evenly distributed in the shape of a spiral around 1 one weeks of packing ring body; 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, and the direction of arrow is the screw-in direction of screw among the figure, and triangle is longer near one side of screw threads Inbound, and triangle is shorter away from one side of screw threads Inbound.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
Lock washer of the present invention, 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 that is connected between part will increase under the effect of a plurality of locking stripeds 4, thereby effectively avoid nut or screw in being in particular surroundings, occur when for example being subject to than strong vibration to become flexible, reach the requirement of locking.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
