Abstract
The utility model relates to a flange plate hexagonal nut with a self-locking function, which consists of a hexahedron (1), a flange plate (2), self-locking deformation points (3) and an inner threaded hole (4), wherein the hexahedron (1) and the flange plate (2) can be a whole, and also can be formed by connection and combination by means of welding and the like, the three self-locking deformation points (3) are arranged on three nonadjacent planes of the hexahedron (1) of the nut and can be formed by means of extrusion and the like. By additionally arranging the flange plate (2) on a common nut, and arranging the self-locking deformation points (3) on the three nonadjacent planes of the hexahedron (1) of the nut, the nut has the self-locking capability, and the flange plate can increase the contacting area between the nut and a tightened part, thus increasing the capability of bearing loads, and improving the reliability of the nut; therefore, the flange plate hexagonal nut can be assembled and disassembled by using mechanic tools such as a sleeve, pneumatic tools and the like, thus being very convenient in installation, and greatly improving installation efficiency.
Description
Technical field
The utility model relates to a kind of nut, particularly relates to a kind of flange plate hexagon nut that has auto-lock function.
Technical background
Nut is a kind of fastening piece of extensive use, but plain nut in use, and especially for the occasion of oscillation exchange and dither, nut returns because of vibration and becomes flexible, and serious returning comes off automatically.In order to prevent that nut from getting loose, reduce potential safety hazard, once invented many nuts that have auto-lock function, in the prior art, many application examples are also arranged, wherein a solution be at nut one end by extrusion-deformation, increase to cooperate the frictional force between rear thread to form self-lock force, connect and self-lock ability thereby nut is had.Because squeezing action, the screw of this self-locking nut becomes ellipse from circle, in use, the assembling difficulty, the efficient of assembling is also very low.
Summary of the invention
The purpose of this utility model provides the flange plate type hexagon nut of a kind of 3 closing ins, band auto-lock function, goes on foot installation, the problem that installation efficiency is low be convenient to the self-locking nut that overcomes in the prior art.
The flange plate hexagon nut that has auto-lock function described in the utility model, by hexahedron, flange plate, self-locking deformation point and interior threaded hole are formed, hexahedron and flange plate can be an integral body, also can connect by modes such as welding and combine, flange plate can be circle, also can be six sides, polygon, shapes such as Qu Bian, on non-conterminous three planes of nut hexahedron, design has the self-locking deformation point, and these three self-locking deformation points can form by extruding or other modes.The utility model is by increasing flange plate on common nut, with self-locking deformation point to being provided with on three non-conterminous planes of nut hexahedron, make nut produce self-lock ability, when screw rod is screwed into nut by the flange plate end, when screw rod enters into the hexahedron part self-locking deformation point of nut, because of the self-locking pressure that distortion produced of screw thread closely links together nut and screw rod, form more firm self-locking, flange plate then can increase the area of contact of nut and fastened part, thereby increase the ability of its bearing load, improved the reliability of nut, thereby can use sleeve and machine tool such as pneumatic to load and unload, install very conveniently, improved installation efficiency greatly.
The utility model compared with the prior art, and is simple in structure, and self-lock ability is strong, and easy to install, can be widely used in each mechanical industry.
Description of drawings:
Fig. 1 is the structural representation of the flange plate type hexagon nut of band auto-lock function described in the utility model;
Fig. 2 is the plan view of Fig. 1.
Among the figure: 1 hexahedron, 2-flange plate, 3-self-locking deformation point, 4-interior threaded hole.
Embodiment:
Embodiment 1:
