Abstract

The utility model relates to a lock washer, and belongs to the technical field of elastic elements. The lock washer is a lock washer with tooth surfaces in a taper shape and an opening dislocation, in the process of screwing a bolt, the lock washer with the tooth surfaces in the taper shape and the opening dislocation is compressed, the opening dislocation is flattened, the taper shape is flattened, elastic force can be increased by changing the two shapes, anti-loose capacity is increased, the tooth surfaces are embedded in the surface of a nut in the flattening process, the anti-loose effect is better, and the anti-loose capacity of the lock washer is improved relative to that of a common lock washer.

Description

Lock washer

Technical field;

The utility model relates to a kind of lock washer, belongs to the elastic element technical field.

Background technique

The spring lock washer is widely used a kind of elastic element in mechanical fastener, and bolt, nut easily produced loosening after being vibrated, and needs to use lock washer locking.Some important use occasions need to have the lock washer of larger coupling mechanism force.And the lock washer of existing structure is difficult to meet the technical requirements with larger coupling mechanism force.

Summary of the invention

The purpose of this utility model is to be difficult to meet the deficiency of the technical requirements with larger coupling mechanism force for the lock washer of existing structure, provides a kind of anti-loose ability larger lock washer.

The purpose of this utility model is achieved through the following technical solutions, and a kind of lock washer has an opening and forms dislocation on the circumference of packing ring, it is characterized in that, two end faces of described packing ring are the flank of tooth.

The cross section of described packing ring is taper.

The utility model is a kind of flank of tooth tapered opening dislocation lock washer, in the bolt tightening process, this flank of tooth tapered opening dislocation lock washer is compressed, the opening dislocation is driven plain, taper also is driven plain, and the change of two shapes all can increase elastic force, and anti-loose ability is strengthened, during pressing, flank of tooth insert nut surface makes anti-loosing effect better, than the anti-loose ability of common lock washer, improves.

The accompanying drawing explanation

Fig. 1 is the utility model perspective view;

Fig. 2 is the left TV structure schematic diagram of Fig. 1;

Fig. 3 is that the A-A of Fig. 2 is to the sectional structure schematic diagram;

Fig. 4 is that the B-B of Fig. 2 is to the sectional structure schematic diagram;

In figure, 1 packing ring, 2 dislocation, 3 flank of tooth.

Embodiment

Further illustrate in conjunction with the accompanying drawings and embodiments the utility model, as shown in Figure 1, thereby the formation that the utility model is a kind of opening has dislocation 2 packing ring 1, has dislocation 2 packing ring 1 and misplaces through bolt tightening the time and 2 be driven plain generation elastic force.As shown in Figure 3, the utility model is radially having individual tapering ∠ α, and during bolt tightening, coning angle is driven plain generation elastic force; As shown in Fig. 1,2,4, two end faces of packing ring 1 are the flank of tooth 3, and during bolt tightening, the locking flank of tooth 3 insert nut surfaces make anti-loosing effect better, and above three factors can make the anti-loose ability of flank of tooth tapered opening lock washer strengthen.

Claims (1)

1. a lock washer, have opening and form dislocation on the circumference of packing ring, and two end faces of packing ring are the flank of tooth, it is characterized in that, the cross section of described packing ring is taper.
