Simultaneously using the first through slot for through-hole wall being in tangent state, friction member is inserted into through slot, because friction member is inserted
Enter the tapered tip-angled shape in end at end, wedge angle can be inserted between nut thread and mounted piece screw thread, will be between thread
Gap is filled up, so that nut body can not be rotated with mounted member, screw thread is locked, and has just been reached the rotation of limitation nut, has been prevented
The only purpose that nut loosens.And when needing to unload lower nut, it is only necessary to friction member is exited from the first through slot, nut body with
Just flexible normal rotation can be obtained again between mounted member, the nut structure being arranged in this way is simple, significant effect, and friction member pole
Easily replacement.
The further setting of the utility model: the end face of the air ring sheet towards nut body side is equipped with elasticity
Part slot, the elastic component slot are arranged in a ring and with nut body in concentric circles.
By adopting the above technical scheme, by the elastic component slot of setting, so that elastic component is set in elastic component slot, Bu Huishou
Vibration influence generates play displacement, influences anti-loosing effect.
The further setting of the utility model: the truncated cone-shaped that the defining flange radially extends, the air ring sheet
It is relatively distant from a side end face of nut body, is equipped with recessed groove compatible with defining flange shape, the defining flange card
Sink into recessed groove.
By adopting the above technical scheme, the recessed groove of setting enables defining flange to be embedded in recessed groove, avoids exposure to
Outside air ring sheet, influence air ring sheet contacted with installation position it is smooth.
The further setting of the utility model: the friction member is made of rubber material.
By adopting the above technical scheme, the friction member being arranged by rubber material, rubber material had both had excellent frictional force,
And can deform to a certain degree, when receiving the screw thread of nut body and mounted member and squeezing, screw thread will not be destroyed.
The further setting of the utility model: the elastic component is spring.

Specific embodiment
As shown in Figs. 1-5, a kind of nut for automobile, including nut body 1, which is equipped with through-hole 11, described
Screw thread 12 is equipped in through-hole 11,1 outer peripheral surface of nut body is equipped with first through slot 16 tangent with 11 inner wall of through-hole, should
Friction member 3, the tapered tip-angled shape in end face of friction member 3 towards the through-hole side, the taper wedge angle are equipped in first through slot 16
End face extends in through-hole 11 along phase tangent line, and 11 1 side end face of through-hole, which is equipped with, connects central siphon 13, in the connection central siphon 13
Ring diameter is greater than 11 diameter of through-hole, is arranged with air ring sheet 2 on 13 outer peripheral surface of connection central siphon, 2 edge of air ring sheet
Connection 13 outer peripheral surface of central siphon does axial sliding fit, and one end end face that the connection central siphon 13 is relatively distant from through-hole 11 is equipped with limit
Position flange 14, compression is provided with elastic component 15 between the air ring sheet 2 and nut body 1.
When installing nut, by 2 side of air ring sheet towards position is mounted, by the air ring sheet 2 of setting along even
13 outer peripheral surface of spindle pipe does axial sliding fit, and compression is provided with elastic component between air ring sheet 2 and nut body 1
15, during installation, air ring sheet 2 is contacted with installation position first, and at this time under external force torsion, nut body 1 continues towards peace
Dress position is tightened, and elastic component 15 is driven to compress, and after nut body 1 is tightened, the resistance of deformation of elastic component 15 drives nut body 1
Axially away from installation position, under the effect of elasticity, the thread of nut body 1 and the thread axial locking of installation position can not be certainly
Right rotation, formation rotation stop effect, and the air ring sheet 2 and elastic component 15 being slidably matched, it can be according to the variation of vibration size, certainly
Positional relationship of both row adjustment between nut body 1, so that nut body 1 remains anti-loose state, and is arranged
Defining flange 14, air ring sheet 2 and nut body 1 can be prevented to be detached from.
Simultaneously using the first through slot 16 for 11 inner wall of through-hole being in tangent state, friction member 3 is inserted into through slot, because of friction
The tapered tip-angled shape in end of 3 insertion end of part, wedge angle can be inserted between nut thread 12 and mounted piece screw thread 12, by spiral shell
Gap between tooth is filled up, so that nut body 1 can not be rotated with mounted member, screw thread 12 is locked, and has just reached limitation
Nut rotation, the purpose for preventing nut from loosening.And when needing to unload lower nut, it is only necessary to by friction member 3 from the first through slot 16
It exits, just flexible can obtain normal rotation again between nut body 1 and mounted member, the nut structure being arranged in this way is simple, effect
Fruit is significant, and friction member 3 is easily replaced.
The end face of the air ring sheet 2 towards 1 side of nut body is equipped with elastic component slot 21, which is in
Annular and with nut body 1 in concentric circles setting.
By the elastic component slot 21 of setting, so that elastic component 15 is set in elastic component slot 21, will not be produced by vibration influence
Raw play displacement, influences anti-loosing effect.
The truncated cone-shaped that the defining flange 14 radially extends, the air ring sheet 2 are relatively distant from the one of nut body 1
On side end face, it is equipped with recessed groove 22 compatible with 14 shape of defining flange, the card of defining flange 14 sinks into recessed groove 22
It is interior.
The recessed groove 22 of setting enables defining flange 14 to be embedded in recessed groove 22, avoids exposure to air ring sheet 2
Outside, influence air ring sheet 2 contacted with installation position it is smooth.
The friction member 3 is made of rubber material.
The friction member 3 being arranged by rubber material, rubber material had both had excellent frictional force, and can become to a certain degree
Shape will not destroy screw thread 12 when receiving the screw thread 12 of nut body 1 and mounted member and squeezing.
The elastic component 15 is spring.
