The special staking swivel nut of aluminium section bar
Technical field
The technical field of swivel nut is the utility model is related to, more particularly to the technical field of aluminium section bar swivel nut.
Background technology
Aluminium section bar is aluminum of the aluminium Jing Guo different cross section shape obtained from hot melt extruded, when needs are on aluminium section bar
When installing miscellaneous part, common installation connected mode typically has welding, riveting or threaded connection at present, when using welding manner
When being attached installation, because the welding performance of aluminium is poor so that welding cost is higher, and bonding strength is relatively low, and other
Part can not be dismantled after being welded on aluminium section bar, inconvenient;When by the way of riveting, because aluminium section bar is usually
Hollow thin-wall part, therefore riveting intensity is relatively low, easily loosens, and the part after riveting can not be dismantled, it is inconvenient;When
When being attached installation using threaded connection, screwed hole is typically opened up on aluminium section bar, then will need fixation using bolt
Part is fixedly mounted on aluminium section bar, because aluminium section bar is generally hollow thin-wall part, is easily loosened using threaded connection, even
It is poor to connect intensity.In addition to above-mentioned several frequently seen connected mode, also there is part to be attached by the way of swivel nut at present, use
The more above-mentioned several connected modes of this kind of connected mode have preferable connective stability, but swivel nut common at present connection still suffers from
The intensity that is connected firmly is not very good situation, is easily loosened in the axial direction in use for some time, and hold
Easily rotate.Meanwhile swivel nut common at present is typically fixed on aluminium section bar using the mode of punching press, and use
For this method, it is necessary to using special decompressor, operation is inconvenient, have impact on installation effectiveness.In addition, current common spiral shell
The structure of set is complex, adds processing and manufacturing cost.
Utility model content
The purpose of this utility model is exactly to provide a kind of simple in construction, manufacture use cost to solve above-mentioned deficiency
It is low, reasonable in design, easy for installation, fixation, it is not easy the special staking swivel nut of aluminium section bar loosened.
In order to solve the above-mentioned technical problem technical solution that the utility model uses is as follows:
The special staking swivel nut of aluminium section bar, it is mainly made up of main body, the rearward end of the main body is provided with base, at this
Annular boss is provided with the anterior main body lateral wall of base, the leading section of main body is provided with boss, in the front portion of main body
Hole is offered, screw thread is provided with the madial wall in the hole, the crowded swollen locking to be connected with the hole is offered at the rear portion of main body
Hole.
It is in regular polygon or annular knurl that the lateral wall of the annular boss, which is set,.
Annular groove is offered in the leading section of the main body so that boss forms retaining ring.
It also includes rivet, and ailhead of the rivet by nail rod and positioned at nail rod leading section is formed, and the nail rod places
In the crowded swollen locking hole of main body, positioned at squeezing on the outside of swollen locking hole, the ailhead is located in the hole of main body in its rear end portion.
Fracture is offered in the nail rod.
The ailhead is tapered.
The beneficial effect that the utility model can be reached using above-mentioned technical solution is:The swivel nut uses the shape of staking
Installation is fixed in formula, can be installed using common hand riveter, enormously simplify installation steps, easy to operate,
Effectively increase installation effectiveness.By carrying out staking to rivet, annular boss is set to expand deformation, so as to be carried out with aluminium section bar
Combine closely, effectively strengthen the locking firmness of the swivel nut and aluminium section bar, effectively prevent the swivel nut in axial direction on
The phenomenon loosened;Meanwhile it is in regular polygon or annular knurl that the lateral wall of annular boss, which is set, it can effectively prevent the swivel nut from occurring
Rotate, further increase the connection tightness of the swivel nut and aluminium section bar;The screw bushing structure is simple, reasonable in design, so as to big
Its structure is simplified greatly, reduces manufacturing cost.

Embodiment
Embodiment 1:As shown in Fig. 1 and Fig. 2, the special staking swivel nut of aluminium section bar, it is mainly made up of main body 1 and rivet,
The rearward end of the main body 1 is provided with base 2, and the diameter of the base 2 is more than the diameter of main body 1, in the main body that the base 2 is anterior
Annular boss 3 is provided with 1 lateral wall, the settable lateral wall of the annular boss 3 is in regular polygon or annular knurl, to prevent from installing
The swivel nut rotates afterwards, and the leading section of main body 1 is provided with boss 9, hole 4 is offered in the front portion of main body 1, in hole 4
Screw thread 5 is provided with madial wall, by putting bolt in the inward turning of hole 4, can need to part to be mounted be fixedly mounted on aluminium section bar
On 10, the crowded swollen locking hole 6 to be connected with hole 4 is offered at the rear portion of main body 1, the aperture for squeezing swollen locking hole 6 is less than hole 4
Aperture.Ailhead 8 of the rivet by nail rod 7 and positioned at the leading section of nail rod 7 is formed, and the ailhead 8 is tapered, and the nail rod 7 is worn
Put in the crowded swollen locking hole 6 of main body 1, its rear end portion is located at the hole 4 of main body 1 positioned at the swollen outside of locking hole 6, the ailhead 8 is squeezed
It is interior.The special staking swivel nut of the aluminium section bar is set in the rear logical of aluminium section bar 10 respectively when mounted, by its annular boss 3 and boss 9
In hole 15 and front through hole 11, then carrying out staking to rivet using hand riveter makes ailhead Final 8 row by squeezing swollen locking hole 6, to squeezing
Swollen locking hole 6 carry out squeeze it is swollen, deform upon annular boss 3, firm holding in the rear through hole 15 of aluminium section bar 10, Fig. 5 for draw
