Abstract
The utility model discloses a kind of high antitorque crowded swollen support swivel nuts, it is made of cylinder, the rear end of the cylinder is provided with limit base, it is provided with annular convex platform on the cylinder lateral wall of the limit base front, the locking teeth being serrated is provided in the circumference of barrel front end, the front end of cylinder is provided with boss, annular locking slot is offered on the lateral wall of the boss, threaded hole is offered in the front of cylinder, crowded swollen taper hole is offered in the rear portion of cylinder, the utility model advantage is：Substantially increase the anti-twisting property of this swivel nut, improve anti-rotation effect, by opening up annular locking slot on the lateral wall of boss, when inside locking teeth insertion aluminium section bar, aluminium section bar deforms upon in embedded annular locking slot, to combine closely with aluminium section bar, axial tensile capacity is significantly improved, the connection tightness of this swivel nut and aluminium section bar is substantially increased.
Description
Technical field
The utility model is related to the technical fields of securing member, more particularly to the technical field of swivel nut.
Background technology
Aluminium section bar is aluminum material of the aluminium by different cross section shape obtained from hot melt extruded, when needs are on aluminium section bar
When installing other component, installation connection type common at present mainly has welding and staking, however the welding performance of aluminium is poor, easily produces
Raw weld defect, staking is easy to cause aluminium section bar deformation, and is easy to happen loosening, and bonding strength is low.For this problem, at present
Occur a kind of aluminium profiles timber-used swivel nut on the market, this swivel nut when in use, by squeeze the side wall of swollen form and aluminium section bar into
Row is stung tight sealed, and in order to achieve the purpose that anti-rotation, the circumference in swivel nut front end is provided with annular knurl, and swivel nut is when mounted by squeezing
Compressive strain makes aluminium section bar be embedded in the groove of annular knurl.However during crimp, only least a portion of aluminium section bar is embedding
Enter into the groove of annular knurl, and this aluminium section bar being partially submerged into is easy to happen fracture, is discontinuous whole with aluminium section bar ontology
Body, therefore when swivel nut is by larger torque, this part aluminium section bar being easy to cause in embedded swivel nut knurled recesses is cut
Shear force and be broken, and detached with aluminium section bar ontology, rotate so as to cause swivel nut, seriously reduce the antitorque energy of swivel nut
Power.In addition, the axial anticreep ability of this swivel nut is also weaker, the bonding strength between aluminium section bar is relatively low.
Utility model content
The purpose of this utility model is exactly to provide one kind in order to solve above-mentioned deficiency and being greatly improved anti-twisting property, is had
Effect prevents from rotating, and axial tensile property is good, and the high height of bonding strength is antitorque to squeeze swollen support swivel nut.
In order to solve the above-mentioned technical problem technical solution that the utility model uses is as follows：
A kind of high antitorque crowded swollen support swivel nut, it is made of cylinder, and the rear end of the cylinder is provided with limit base,
It is provided with annular convex platform on the cylinder lateral wall of the limit base front, the locking being serrated is provided in the circumference of barrel front end
Tooth is provided with boss in the front end of cylinder, annular locking slot is offered on the lateral wall of the boss, in the front of cylinder
Threaded hole is offered, crowded swollen taper hole is offered in the rear portion of cylinder.
Chamfering is offered in the front of the locking teeth.
The threaded hole connects with crowded swollen taper hole.
The lateral wall setting of the annular convex platform is in regular polygon.
The front end of the annular convex platform offers chamfering.
The utility model is using the attainable advantageous effect of above-mentioned technical solution institute：Pass through the week in barrel front end
Portion is provided with the locking teeth being serrated, and opens up chamfering in the front of locking teeth so that inside locking teeth insertion aluminium section bar
When, the part that aluminium section bar deforms can flow sufficiently into filling to the rectangle card slot between adjacent locking teeth, locking teeth
It can closely be interlocked with aluminium section bar, and the aluminium section bar being embedded in rectangle card slot is not easy to break, be with aluminium section bar ontology
One continuous whole so that the aluminium section bar part in rectangle card slot has very strong anti-shear ability, to significantly
Improve the anti-twisting property of this swivel nut；In addition, squeeze swollen taper hole by squeeze it is swollen after so that be in regular polygon annular convex platform and aluminium profiles
Material securely set together by lock, to further improve anti-rotation effect.By opening up annular locking on the lateral wall of boss
Slot, when inside locking teeth insertion aluminium section bar, aluminium section bar deforms upon in embedded annular locking slot, to closely be tied with aluminium section bar
It closes, significantly improves axial tensile capacity, substantially increase the connection tightness of this swivel nut and aluminium section bar.

Fig. 2 is the schematic cross-sectional view of Fig. 1；
Fig. 3 is the present invention looks up structural representation of Fig. 1；
Fig. 4 and Fig. 5 is the scheme of installation of the utility model.
Specific implementation mode
Shown in Fig. 1, Fig. 2 and Fig. 3, a kind of high antitorque crowded swollen support swivel nut, it is made of cylinder 1, in the cylinder 1
Rear end is provided with limit base 2, is provided with annular convex platform 3 on 1 lateral wall of cylinder of 2 front of limit base, the annular convex platform 3
Lateral wall can be arranged in regular polygon, the front end of annular convex platform 3 offers chamfering 18,1 front end of cylinder circumference be arranged
There is the locking teeth 4 being serrated, chamfering 5 offered in the front of the locking teeth 4, the front end of cylinder 1 is provided with boss 6,
Annular locking slot 7 is offered on the lateral wall of the boss 6, threaded hole 8 is offered in the front of cylinder 1, after cylinder 1
Crowded swollen taper hole 9 is offered in portion, the threaded hole 8 can also connect with crowded swollen taper hole 9.
As shown in Figure 4, this swivel nut when mounted, first opens up first through hole 11 and second respectively on the side wall of aluminium section bar 10
Then through-hole 12 penetrates this swivel nut in aluminium section bar 10 from first through hole 11, and so that annular convex platform 3 and boss 6 is distinguished holding and exist
At first through hole 11 and the second through-hole 12, then aluminium section bar 10 is mounted on pedestal 13, and the head 14 of pedestal 13 is made to be inserted into
In threaded hole 8, then the head 16 of punch 15 is caught in crowded swollen taper hole 9.As shown in Figure 5, this swivel nut is carried out by punch 15
Punching press generates crowded swollen effect to squeezing swollen taper hole 9 using the head 16 of punch 15, so that annular convex platform 3 is expanded outward, with first through hole
11 interference fits, and locked with first through hole 11.During punching press downward to this swivel nut, the insertion of locking teeth 4 second
Aluminium section bar 10 in aluminium section bar 10 at through-hole 12, while herein, which is squeezed, to deform, embedded annular locking slot 7 and adjacent
In rectangle card slot 17 between locking teeth 4.
