Abstract
The utility model discloses a shaped nut expansion screw, being composed of a screw bolt, an expansion sleeve and a washer. The end of a screw thread of the screw is provided with a shaped screw nut matched with the screw thread. The shaped screw nut forms a cone shape, one end can be sheathed in the expansion sleeve. The expansion sleeve, the washer and a spring washer are respectively sheathed between the shaped screw nut and the tail part of the screw bolt. The utility model which has the advantages of simple structure and convenient use is suitable for fixing multiple objects.
Description
A kind of abnormity nut setscrew belongs to five metals class technical field commonly used.
In background technique, setscrew (metal) generally is made up of special-shaped screw, expansion sleeve, nut, packing ring.One end of abnormity screw is a cone, and cone is made the sheet usefulness on the jack-up expansion sleeve, and the other end is the screw thread of screw, is screwed with nut on the screw thread.Cone one end is pressed in the body of wall, and the other end is stayed outside the body of wall.Setscrew is the nut on the tightening the screw fixedly the time, makes closely to contact a sheet jack-up on the expansion sleeve with body of wall, reaches the purpose that screw expands, thus fixed object.But this means of fixation has its shortcoming, and when nut was tightened, screw thread one end of screw was exposed at the body of wall outside, and exposing of having is longer, influences attractive in appearance.If bared end is removed, bother.
The utility model abnormity nut expansion thread is in order to overcome above-mentioned shortcoming, a kind of abnormity nut setscrew that does not reveal the screw thread end to be provided.
The utility model abnormity nut setscrew is by realizing that so special-shaped screw and nut are substituted by bolt and abnormity nut.Abnormity nut is located at the screw section end of bolt, and screw thread is complementary, and it is cone-shaped that abnormity nut is, and an end can be inserted in expansion sleeve.Between bolt tail and abnormity nut, be inserted in expansion sleeve, packing ring and spring washer respectively.Fixedly the time, tighting a bolt makes abnormity nut be inserted in expansion sleeve, and the jack-up sleeve pipe props up sheet, reaches fixing purpose.
Fig. 1 is the structural drawing of the special-shaped nut setscrew of the utility model.
Below in conjunction with accompanying drawing the utility model abnormity nut setscrew is described in detail.1 is abnormity nut among Fig. 1, is cone-shaped, and an end can be inserted in expansion sleeve, makes a sheet jack-up of sleeve pipe, and 2 is expansion sleeve, and 3 is packing ring, and 4 is spring washer, and 5 is bolt, and 5-1 is the afterbody of bolt, and 5-2 is the screw section of bolt.During operation,, make and tighten mutually with expansion sleeve 2, packing ring 3, the spring washer 4 of 1 on the special-shaped nut of the screw section 5-2 that is located at bolt or unclamp as long as turn bolt tail 5-1.When tightening, a sheet of abnormity nut 1 jack-up expansion sleeve 2 reaches fixing purpose.The afterbody 5-1 of bolt 5 can make the decoration shape, makes it environmental beauty.The size of abnormity nut setscrew can design corresponding size according to different requirements.
Characteristics simple in structure, easy to use, good fixing effect that the utility model Special nut expansion screw has. It is widely used in the fixing of various objects.
