Specific implementation mode
As shown in figure 1 to figure 13, the utility model embodiment provides a kind of check bolt nut assembly, including:Bolt
1, fastening nut 2, spring washer 3, locking nut 4 and elastic element 5, the bolt 1 is across first by fastening workpiece 6 and second
By the unthreaded hole of fastening workpiece 7 successively in mating connection, the spiral shell with fastening nut 2, spring washer 3, locking nut 4 and elastic element 5
Screw thread on bolt 1 is divided into 9 two parts of left hand thread 8 and right-handed thread, is set respectively on the side wall of fastening nut 2 and locking nut 4
There is axial rectangular straight slot 10, radial rectangular channel 11, elastic element 5 and fastening nut 2, lock are additionally provided on the side wall of fastening nut 2
Axial rectangular straight slot 10 on tight nut 4 matches, while there are two the sides of clamp 12 and fastening nut 2 for 5 lower end of elastic element
Radial rectangular channel 11 on wall matches.
The diameter of the right-handed thread 9 of this bolt 1 is more than the diameter of left hand thread 8.
It is respectively equipped with the axial rectangular straight slot of identical size on each side wall of this fastening nut 2 close to side wall in an axial direction
10, this axial rectangular straight slot 10 is respectively provided at the middle position of each side wall of the fastening nut 2, the radial direction side of fastening nut 2
To also being provided with radial rectangular channel 11.
The axial direction of this locking nut 4 is equipped with axial rectangular straight slot identical with fastening nut 2 10.
The installation process of check bolt nut assembly shown in FIG. 1 is:Bolt 1 is passed through first by fastening workpiece 6 and the
Two by the unthreaded hole of fastening workpiece 7, and dextrorotation screws in fastening nut 2 and fastens, and loads onto spring washer 3, left-handed screw-in locking nut 4 is simultaneously
Holddown spring washer 3 makes spring washer 3 generate enough flexible deformations, simultaneously under conditions of ensureing that fastening nut 2 fastens
The axial rectangular straight slot 10 of the axial rectangular straight slot 10 and locking nut 4 that ensure fastening nut 2 is aligned, the elasticity of elastic element 5
Material is made, and the middle section of elastic element is annular, and the intermediate throughholes of annular section are sleeved on bolt 1, and the two of annular section
End is rectangular tab part, and rectangular tab part is caught in the axial rectangular straight slot 10 of fastening nut 2 and locking nut 4 simultaneously,
And 2 clamps 12 of elastic element 5 are caught in the radial rectangular straight slot 11 of fastening nut 2.
When dismounting, reversed 2 eave tiles 13 for pressing elastic element 5 simultaneously make 2 clamps 12 of elastic element 5 from fastening
Deviate from the radial rectangular straight slot of nut 2, remove elastic element 5, then removes locking nut 4, spring washer 3 and tight successively
Gu nut 2 is finally extracted bolt 1 out by fastening workpiece 6 and second from first in the unthreaded hole of fastening workpiece 7.
Locking process is:When fastening nut 2 is to be loosened, fastening nut 2 rotates left hand direction, in elastic element 5
Under effect, also left hand direction rotates locking nut 4, and such fastening nut 2 and locking nut 4 are close to each other in an axial direction.Due to
Spring washer 3 is installed, and spring washer 3 can produce enough elasticity and become between fastening nut 2 and locking nut 4
Shape, so spring washer 3 just hinders fastening nut 2 and locking nut 4 close to each other in an axial direction, to prevent fastening nut 2 left
Rotation rotation, achievees the purpose that locking.
When locking nut 4 is to be loosened, 4 palpus clockwise direction rotation of locking nut, under the action of elastic element 5, fastening
Also clockwise direction rotates nut 2, and such locking nut 4 and fastening nut 2 are axially away from one another.First is hindered by fastening workpiece 6
Hinder fastening nut 2 to be axially distant from locking nut 4, to prevent 4 dextrorotation of locking nut from rotating, achievees the purpose that locking.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
