Abstract
The utility model belongs to the technical field of anti-loosing components, and relates to an anti-loosing spacer. The spacer comprises a circular hole and retaining sides; the retaining sides are divided into two groups or three groups; each group comprises two retaining sides; the central lines of the two retaining sides of each group share the same straight line; the included angle between two adjacent straight lines is 60 DEG; and the center of the circular hole (5) is on the intersection point of all the straight lines. Through bending deformation of the retaining sides of the spacer, a nut and a connecting part are relatively static under the action of the spacer, thereby preventing the nut from getting loose. The utility model has effective anti-loosing effect particularly on nuts under large impact force, large vibration and frequent vibration.
Description
Technical field
The utility model belongs to the anti-release member technical field, is a kind of loosening pad of bolts and nuts connection that is used to prevent specifically.
Background technique
At present, be used for nut, bolted check washer mainly is the bullet pad, the elasticity pretightening force that produces by compression bullet pad realizes the purpose of nut anti-looseness.Yet for impacting the big and frequent occasion of big vibration, because the bullet pad fatigue failure occurs easily under frequent high vibration environment, its elasticity pretension effect reduces, thereby has lost the effect that prevents nut loosening.In addition, the elastic reaction of bullet pad can give nut the elastic force to loosening direction when nut begins to become flexible, and at this moment the bullet pad plays the effect of accelerating nut loosening again, so the problem of nut loosening occurs once more.
Summary of the invention
The utility model technical issues that need to address are, overcome disadvantages of background technology, provide a kind of simple in structure, and the bolt and nut that prevents of peace, easy accessibility connects loosening anti-release member.
The utility model is achieved through the following technical solutions: check washer, form by circular hole and rib, it is characterized in that, rib is two groups or three groups, each group is made up of two ribs, the centerline of two ribs of each group is on same straight line, and the angle of adjacent two straight lines is 60 °, and the center of circle of circular hole (5) is positioned on the intersection point of each straight line.
Below the utility model is described in detail, the utility model is the plastic deformation by pad, it is relative static that nut and link are formed, and realizes preventing the purpose of nut loosening, and the material of check washer can be selected according to the density of load of bolt.During use, bolt is passed the circular hole of check washer, again nut normally is connected on the bolt also fastening, make check washer between nut and link, the bending deflection of check washer rib is closely contacted with fastening piece with nut respectively, guarantee that simultaneously nut and link have a rib and its tight contact at least.Thereby make nut realize relative static by the check washer after being out of shape with link.When nut has the trend of loosening rotation under effects such as impact, vibration, the trend of rotation can be passed to check washer, check washer passes to link with rotation trend, is stopped the trend of rotation at last by link, has avoided the loosening of nut.Reached the purpose that prevents nut loosening.
The beneficial effects of the utility model are, utilize the distortion of check washer to contact closely with nut, link respectively, realize relative static between nut and the link, reached the purpose that prevents nut loosening, the nut under the environment big for impact force especially, that vibration is big and frequent has effective anti-loosing effect.Because general nut all is positive hexagonal prism, so the center line angle of every two adjacent groups rib is set at 60 °, after rib is bent, just can fit with the side of nut like this.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, check washer has two groups of ribs, rib 1 and rib 3, rib 2 and rib 4 are in respectively on the same straight line, and the angle of two straight lines is 60 °, the center of circle of circular hole 5 is positioned on the intersection point of two straight lines, bolt 8 passes link 6, behind the check washer, again with being threaded of nut 7, before tightening nut 7, the bending that earlier rib 1 distortion made progress makes it closely contact with nut 7, again with nut screwing clamping, and then with rib 2, rib 3 and rib 4 bending deflections, closely contact with link 6, thereby realize nut 7 by check washer, link 6 static relatively.The loosening rotation trend of nut 7 under large impact vibrations can pass to link 6 by the rib of check washer, stop rotation trend by link 6 again, reaches the locking purpose of nut 7.During dismounting, make the check washer rib be deformed to initial installment state, can normally dismantle nut.
As shown in Figure 2, check washer has three groups of ribs, rib 1 and rib 3, rib 2 and rib 4, rib 5 and rib 6 are in respectively on the same straight line, and the angle of adjacent two straight lines is 60 °, the center of circle of circular hole 5 is positioned on the intersection point of three straight lines, bolt 8 passes link 6, behind the check washer, again with being threaded of nut 7, before tightening nut 7, earlier with rib 1,6 distortion closely contact with nut 7 rib 4 with rib, again with nut screwing clamping, and then with rib 2, rib 3 and rib 5 bending deflections, closely contact with link 6, thereby realize nut 7 by check washer, link 6 static relatively.The loosening rotation trend of nut 7 under large impact vibrations can pass to link 6 by the rib of check washer, stop rotation trend by link 6 again, reaches the locking purpose of nut 7.During dismounting, make the check washer rib be deformed to initial installment state, can normally dismantle nut.
