Embodiment
In order to which the technical solution of the utility model is explained further, below by specific embodiment come to the utility model into
Row elaborates.
A kind of stop nut disclosed in the utility model, as shown in Figure 1, including nut body 1, elastic washer 2 and block
3, the elastic washer 2 is coaxial to be arranged on the axial one end of nut body 1, and the block 3 is arranged on the axis of nut body 1
Dust can be prevented by being used to cover the threaded hole 11 of nut body 1 to the other end, and impurity, which enters in threaded hole 11, causes nut sheet
The thread abrasion of body and bolt influences service life, is equipped between the nut body 1, block 3 or nut body 1 and block 3
Make the connection structure not easily to fall off of block 3, the concrete structure of connection structure does not limit specifically here, can use same domain or other
The structure with identical action effect in field.
Elastic washer 2 disclosed in the utility model, as shown in Figures 2 and 3, including washer body 21 and elastic strip 22, institute
It is to connect washer body 21 around 21 360 degree of a plurality of layings of washer body, one end of each elastic strip 22 to state elastic strip 22,
Each elastic strip 22 is gradually deflected away from from one end that washer body 21 is connected to the other end to the axial one side of washer body 21, shape
Into elasticity, 22 in the axial one side of washer body 21 be protrusion, in the axial another side of washer body 21 to be recessed, by bullet
Property lateral from the protrusion one recessed side compression of bar 22 when, elastic strip 22 produces elastic-restoring force, only therein shown in figure
One kind realizes structure, also has other structures form to realize, does not enumerate here, the structure shown in figure, the washer body
21 be circular ring type, and the elastic strip 22 cuts out one section of wire casing 211 and to the axial side of washer body 21 from washer body 21
It is bent to form, the wire casing 211 runs through the axial width of elastic washer 2, and one end of the wire casing 211 is opening in washer body
21 lateral wall or madial wall, shown in figure in outer side wall, can be set according to practical application, the wire casing 211 it is another
Hold as closed end, it is circumferentially extending between the lateral wall and madial wall of washer body 21 along washer body 21, shown in figure
Wire casing 211 is L-type structure, and elastic washer 2 can be made of spring steel, the connection structure intensity of elastic strip 22, elastic anchorage force
It is preferable with elastic-restoring force.Elastic strip 22 is preferably uniformly arranged three or four and is advisable in the present embodiment, is so propped up in elasticity
Active force can be uniformly distributed the balance for keeping elastic washer 21 during support, if active force deviation occurs in 21 imbalance of elastic washer
The loosening of nut may also can be caused, which not reach anti-loosing effect and nut body 1 and the thread abrasion of bolt, influences service life.
When applied to automotive tyre nut, the axial width of elastic washer 2 is preferably 5-7 millimeters, and others application refers to it
The parameters such as the size of the bolt and nut of application is small, elastic strip coefficient of elasticity are set to refer to.
Nut body 1 described in the present embodiment is connected setting with elastic washer 2 for riveted, as shown in FIG., the elasticity
2 opposing nut body 1 of packing ring is rotatable, and elastic washer 2 is typically what is contacted with treating locking body, therefore both are mutually rotatable,
When tightening nut body 1, elastic washer 2 can be reduced and rotated, reduced elastic washer 2 and treat that institute's solid friction is worn, institute in figure
State nut body 1 and the connection structure of elastic washer 2 is, 1 end of nut body is extended with the lantern ring 12, the elastic washer
2 are set in outside the lantern ring 12, and the inside edge of the elastic washer 2 is equipped with the outer edge that the riveted step ring 23 to sink supplies the lantern ring 12
Riveted is caught on, so that elastic washer 2 and nut body 1 link together again rotatably, when tightening nut body 1 to bullet
Property packing ring 2 press, elasticity of compression bar 22, while elastic strip 22 produces elastic-restoring force, withstanding nut body 1 makes its with respect to bolt
For close-fitting conjunction state, so as to fulfill elastic anti-seismic anti-loosing effect.In addition, the elastic washer 2 can also connect with nut body 1 to be fixed
Setting is connect, if the side of 2 elastic strip 22 of the elastic washer protrusion is needed outside in this way, recessed side needs court
The pressure to elastic strip 22 just can be achieved to nut body 1.
For applying on automotive tyre nut, due to there is the problem of contact area, the overall diameter of elastic washer 2 is larger,
Preferably to press to elastic washer 2, the nut body 1 connects one end of elastic washer 2 equipped with corresponding with elastic washer 2
Top pressure ring 13, for 2 top pressure of elastic washer, it is as shown in Figure 1.
The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field
The appropriate change or modification that those of ordinary skill does it, all should be regarded as not departing from the patent category of the utility model.
