Fig. 2 is the pretightning force lock washer lower surface dimensional structure diagram that the utility model preferred embodiment uses.
Fig. 3 is dimensional structure diagram of the utility model preferred embodiment after installation is complete.
Mark represents：Pretightning force lock washer 1, upper surface 11, upper surface tooth engaged 111, lower surface 12, upper surface occlusion
Tooth 121, support component 2, screw rod 3, nut 4, lines 5.
Specific implementation mode
The utility model is described in detail below in conjunction with attached drawing.
As shown in Figs. 1-3, a kind of fastener constructions using pretightning force lock washer of the utility model, including support member
Part 2, screw rod 3 and nut 4, screw rod 3 penetrate support component 2, and nut 4 is screwed on screw rod 3, and two pieces pretightning force lock washer 1 is set
It sets between support component 2 and nut 4 and is penetrated by screw rod 3, the hardness of support component 2 and nut 4 is less than the locking pad of pretightning force
The axis projection of the hardness of circle 1, two pieces pretightning force lock washer 1 is annulus, and annulus is hollow so that screw rod 3 passes through.Pretightning force is anti-
Loose washer 1 has upper surface 11 and lower surface 12 in the axial direction, uniform thickness there are one tools between upper surface 11 and lower surface 12,
Upper surface 11 is uniformly raised from the inside the edge of the circle of the outer circular edge of annulus in an axial direction, and lower surface 12 is in an axial direction from the outer circumferential edge of annulus
The inside the edge of the circle of edge is uniformly recessed, and the internal circle for forming annulus is high and three-dimensional bowl structure that outer circumferential edge is low, in use, pretightning force
Lock washer 1 can compress deformation under axial compressive force effect and the inner circle of annulus is made to be in contour horizontal line with outer circle, that is, be in
Flat form, at this point, since pretightning force lock washer 1 is to be deformed into flat form from initial volumetric bowl structure through axial,
There is elastic restoring forces inside it, after external load, can quickly fill up between connector and gap or relatively sliding occur
It moves, to keep the reliability and compactness of connection.After installation is complete, support component 2 and nut 4 connect with pretightning force lock washer 1
Tactile surface forms numerous lines 5 stung out by tooth engaged, and lines 5 prevents fastener negative direction to relax.Upper surface 11 and circle
The tooth engaged of ring inner circle infall, which is chamfered, to be polished, and the tooth engaged of lower surface 12 and annulus outer circle infall, which is also chamfered, to be polished,
Thus, for pretightning force lock washer 1 when being locked with fastener, the contact with fastener is more stable and without hindrance.
Upper surface 11 and lower surface 12 all have evenly distributed tooth engaged, and upper surface tooth engaged 111 is that opening is clockwise
The inclined-plane tooth of direction, lower surface tooth engaged 121 are the inclined-plane tooth of direction counterclockwise of being open.Thus, fastener is suitable in locking
It and locks clockwise, either still upward, the opening of inclined-plane tooth is all suitable for lower surface 12 upward for upper surface 11 at this time
Fastener locking direction, locking torsion is reduced；When fastener is vibrated loose, reverse inclined-plane tooth can then prevent fastener
Relaxation.
When a kind of mode is installed, 12 make-up of lower surface of two pieces pretightning force lock washer 1, after installation is complete, two pieces pre-tightens
12 tooth engaged of lower surface of power lock washer 1 is mutually twisted.
When another way is installed, 11 make-up of upper surface of two pieces pretightning force lock washer, after installation is complete, two pieces pre-tightens
11 tooth engaged of upper surface of power lock washer 1 is mutually twisted.
When yet another approach is installed, wherein the upper surface 11 of a pretightning force lock washer 1 and another pretightning force are locking
The lower surface 12 of washer 1 engages and tooth engaged is mutually twisted.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.
