Description

Hollow aluminum section is special to squeeze swollen inner support anti-rotation swivel nut

Technical field

The utility model is related to the technical field of swivel nut, 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 is threadedly coupled 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 fixation will be needed 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 Connect intensity poor.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 preferably connective stability, but swivel nut connection common at present is still suffered from The intensity that is connected firmly is not very good situation, is easily loosened in the axial direction, and hold in use for some time Easily rotate, and the installation method of current common swivel nut is relatively complicated, it is not very convenient to operate, and have impact on installation effect Rate.

Utility model content

The purpose of this utility model is exactly to provide a kind of simple in construction in order to solve above-mentioned deficiency, reasonable in design, peace Dress is convenient, fixation, is difficult to loosen, and the high hollow aluminum section of bonding strength is special to squeeze swollen inner support anti-rotation swivel nut.

The technical solution that in order to solve the above-mentioned technical problem the utility model uses is as follows：

Hollow aluminum section is special to squeeze swollen inner support anti-rotation swivel nut, and it is mainly made up of main body, is set in the rearward end of the main body Base is equipped with, annular boss is provided with the anterior main body lateral wall of the base, the lateral wall of the annular boss is in just polygon Shape, boss is provided with the leading section of main body, shoulder hole is offered in the inside of main body, the shoulder hole is by the big footpath of coaxial line Hole, central diameter hole and diameter holes are constituted, and screw thread is provided with the madial wall in central diameter hole, and large diameter hole is located at the leading section of main body, made Obtain boss formation retaining ring.

The front end face of the annular boss is in inclined-plane.

The rear end face in the central diameter hole and the front end face flush of annular boss.

The lateral wall of the annular boss is in dodecagon or positive ten octagon.

Chamfering is offered on the seamed edge in dodecagon or positive ten octagonal annular boss.

It is in polygon that the lateral wall of the retaining ring, which is set, or is provided with its lateral wall circumferentially anti-skidding Line.

The shoulder hole is through hole.

The shoulder hole is blind hole.

The beneficial effect that the utility model can be reached using above-mentioned technical solution is：The hollow aluminum section is special to be squeezed After swollen inner support anti-rotation swivel nut is installed on aluminium section bar, retaining ring is deformed upon, and is locked with aluminium section bar, meanwhile, annular boss hair Raw deformation, and being locked with aluminium section bar so that the special both ends for squeezing swollen inner support anti-rotation swivel nut of the hollow aluminum section are and aluminium section bar Locking, so as to substantially increase fastening effect, can prevent the movement of the swivel nut in axial direction, meanwhile, the outside of annular boss It is in regular polygon that wall, which is set, can effectively prevent the swivel nut from rotating so that the connection of the swivel nut and aluminium section bar becomes very tight Gu；The screw bushing structure is simple, it is easy to process, and can effectively reduce manufacture use cost；The installation method of the swivel nut is easy to operate fast Victory, is substantially shorter the set-up time, improves installation effectiveness, and installation quality is easily controllable.
