Description
Technical field
The utility model relates to fastener areas, and in particular to a kind of automobile-used stop nut.
Background technique
Currently, the locking mode of bolt mainly include the following types: 1, using split pin, lock washer, iron wire locking etc. side
Formula；
2, using modes such as spring washer, double nut lockings；
3, using deformation screw thread, the modes such as thread friction power are increased；
4, using modes such as chemical gluing locking screw threads.
The above locking mode be suitble to it is static fixed, but on vehicle in use, need in view of vehicle jolts when production
Raw vibration, this vibration easily cause nut to loosen.
Summary of the invention
The utility model provides a kind of locking spiral shell for being adapted to high-intensitive vibration to solve the deficiency of above-mentioned technology
It is female.
The technical solution of the utility model includes: a kind of stop nut, including nut body, the nut body center are equipped with logical
Hole, the through-hole is interior to be equipped with screw thread, it is characterised in that: one side end face of through-hole, which is equipped with, connects central siphon, in the connection central siphon
Ring diameter is greater than through-hole diameter, is arranged with air ring sheet on the connection central siphon outer peripheral surface, the air ring sheet is along connecting shaft
Pipe outer peripheral surface does axial sliding fit, and one end end face that the connection central siphon is relatively distant from through-hole is equipped with defining flange, described
Compression is provided with elastic component, a side end face of the air ring sheet far from nut body between air ring sheet and nut body
It is equipped with anti-skidding convex ribs.
By adopting the above technical scheme, when nut is installed, by air ring sheet side towards position is mounted, pass through setting
Air ring sheet does axial sliding fit along connection central siphon outer peripheral surface, and setting is compressed between air ring sheet and nut body
Flexible part, during installation, air ring sheet are contacted with installation position first, and at this time under external force torsion, nut body continues
It is tightened towards installation position, elastic component is driven to compress, after nut body is tightened, the resistance of deformation of elastic component drives nut body axis
To far from installation position, under the effect of elasticity, the thread of nut body and the thread axial locking of installation position can not revolve naturally
Turn, forms anti-loosing effect, and the air ring sheet and elastic component being slidably matched, meeting voluntarily be adjusted according to the variation of vibration size
Positional relationship between the two and nut body, so that nut body remains anti-loose state, and the limit convex being arranged
Edge can prevent air ring sheet and nut body to be detached from.By the anti-skidding convex ribs of setting, increase air ring sheet and mounting portion
Frictional force between position.
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 elastic component is spring.
Detailed description of the invention
Fig. 1 is the structure chart 1 of the utility model embodiment；
Fig. 2 is the explosive view of the utility model embodiment；
Fig. 3 is the structure chart 2 of the utility model embodiment；
Fig. 4 is sectional view at B-B in Fig. 3.
Specific embodiment
As shown in Figs 1-4, a kind of stop nut, including nut body 1, which is equipped with through-hole 11, described
Screw thread 12 is equipped in through-hole 11,11 1 side end face of through-hole is equipped with connection central siphon 13, and 13 annular diameters of connection central siphon are big
In being arranged with air ring sheet 2 on 11 diameter of through-hole, 13 outer peripheral surface of connection central siphon, the air ring sheet 2 is along connection central siphon
13 outer peripheral surfaces do axial sliding fit, and one end end face that the connection central siphon 13 is relatively distant from through-hole 11 is equipped with defining flange
14, compression is provided with elastic component 15 between the air ring sheet 2 and nut body 1, and the air ring sheet 2 is far from nut
One side end face of ontology 1 is equipped with anti-skidding convex ribs 23.
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 anti-loosing 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.By the anti-skidding convex ribs 23 of setting, increase ring
Frictional force between shape spacer elements 2 and installation position.
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 elastic component 15 is spring.
