Abstract
It the utility model is related to a kind of interior setscrew, category mechanical engineering Element Technology field.The utility model includes winged nut, expansion sleeve, packing ring, bolt, bolting pad upper gasket is inserted into the interior circular hole of expansion sleeve, the slide system fin of winged nut is inserted into the axial cut-outs of expansion sleeve, bolt is tightened after being put into wall hole and pulls the axial movement of winged nut, make expansion sleeve spreading using the outer conical surface of winged nut, reaching makes interior setscrew be fastened on the purpose on wall.The slide system fin of winged nut can not only prevent winged nut wall hole it is hollow then and prevent expansion sleeve from being dallied in wall hole, prevent wall hole because interior setscrew rotate increase, reach more preferable fastening effect.
Description
Technical field
It the utility model is related to a kind of interior setscrew, category mechanical engineering Element Technology field.
Background technology
Setscrew is to reach fixed effect using wedge-shaped gradient to promote expansion to produce friction grip force, in water
Fastening object on mud, brick wall, common setscrew are：One, screw is screw thread, and one is tapered, outside iron clad skin cylinder,
One section of iron sheet cylinder has some otch, and screw is dragged outward with nut in screw and cylinder stopcock to wall hole, screw conehead is circle
Cylinder spreading, the problem of being allowed to be fastened on wall, existing is that cylinder can not rotate with nut, otherwise can be loosened.
The content of the invention
The utility model purpose is to provide a kind of interior setscrew, using the winged nut of anti-skidding slide system, makes expansion
Screw obtains quick and easy for installation, and fastening effect is good.
The technical solution adopted in the utility model is：A kind of interior setscrew, including winged nut 1, expansion sleeve 2, packing ring
3rd, bolt 4, the winged nut 1 include internal thread hole 5, outer conical surface 6, slide system fin 7, and two panels slide system fin 7 is symmetrical
The both sides of outer conical surface 6 are arranged on, the expansion sleeve 2 includes interior circular hole 8, inner circle taper hole 9, axial cut-outs 10；The bolt 4 pads
Upper gasket 3 is inserted into the interior circular hole 8 of expansion sleeve 2, and rotating bolt 4 is allowed to be connected with the internal thread hole of winged nut 15, cylindrical
The conical surface 6 is brought into close contact with inner circle taper hole 9, and the slide system fin 7 of winged nut 1 is inserted into the axial cut-outs 10 of expansion sleeve 2, is put
Bolt 4 is tightened after into wall hole pulls winged nut 1 to move axially, and expansion sleeve 2 is risen using the outer conical surface 6 of winged nut 1
Open.
Preferably, described winged nut 1 is integrally formed.
Operation principle of the present utility model is：Bolt 4 is padded upper gasket 3 to be inserted into the interior circular hole 8 of expansion sleeve 2, rotated
Bolt 4 is allowed to be connected with the internal thread hole 5 of winged nut 1, and the axial direction that the slide system fin 7 of winged nut 1 is inserted into expansion sleeve 2 is cut
In mouth 10, bolt 4 is tightened after being put into wall hole and pulls winged nut 1 to move axially, is made using the outer conical surface 6 of winged nut 1
The spreading of expansion sleeve 2, reaching makes interior setscrew be fastened on the purpose on wall.
The beneficial effects of the utility model are：The slide system fin 7 of winged nut 1 can not only prevent winged nut 1 in wall
Hole is hollow to transfer and prevents expansion sleeve 2 from being dallied in wall hole, prevents wall hole from increasing because interior setscrew rotates, and reaches preferably tight
Gu effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is three dimensional structure diagram of the present utility model；
Fig. 3 is the three dimensional structure diagram of winged nut 1；
Fig. 4 is the structure sectional view of expansion sleeve 2.
In figure respectively marked as：1- winged nuts, 2- expansion sleeves, 3- packing rings, 4- bolts, 5- internal thread holes, 6- outer conical surfaces,
7- slide system fins, circular hole in 8-, 9- inner circle taper holes, 10- axial cut-outs.
Embodiment
With reference to the accompanying drawings and examples, the utility model is described in further detail, but content of the present utility model is not
It is limited to the scope.
Embodiment 1：As Figure 1-4, a kind of interior setscrew, including winged nut 1, expansion sleeve 2, packing ring 3, bolt 4,
The winged nut 1 includes internal thread hole 5, outer conical surface 6, slide system fin 7, and two panels slide system fin 7 is symmetrical arranged outside
The both sides of circular conical surface 6, the expansion sleeve 2 include interior circular hole 8, inner circle taper hole 9, axial cut-outs 10；The bolt 4 pads upper gasket 3
Be inserted into the interior circular hole 8 of expansion sleeve 2, rotating bolt 4 is allowed to be connected with the internal thread hole 5 of winged nut 1, outer conical surface 6 with it is interior
Conical bore 9 is brought into close contact, and the slide system fin 7 of winged nut 1 is inserted into the axial cut-outs 10 of expansion sleeve 2, is installed interior swollen
It is put into after swollen screw in wall hole, tightens bolt 4 and pull winged nut 1 to move axially, make the spreading of outer conical surface 6 of winged nut 1
The inner circle taper hole 9 of expansion sleeve 2 and then make the spreading of expansion sleeve 2, the slide system fin 7 of winged nut 1 can not only prevent winged nut 1
Wall hole it is hollow then and prevent expansion sleeve 2 from being dallied in wall hole, prevent wall hole because interior setscrew rotate increase, reach more preferable
Fastening effect.
Further, described winged nut 1 is integrally formed, simple in construction, easy to process.
Specific embodiment of the present utility model is explained in detail above in conjunction with accompanying drawing, but the utility model is not
It is limited to above-mentioned embodiment, in those of ordinary skill in the art's possessed knowledge, this practicality can also be not being departed from
Various changes can be made on the premise of new objective.
