Detailed Description

For a more clear and complete description of the technical solution of the present invention, the following description is made with reference to the accompanying drawings.

Referring to fig. 2-4, the utility model relates to a fixed firm nut that draws, including the nut cover body 1, nut body 2, the nut cover body 1 includes bottom 13, supporting part 11, fixed part 12 passes through supporting part 11 connects bottom 13, fixed part 12 includes first clamping part 120, expansion portion 121, by fixed orifices 122 that expansion portion 121 encloses, nut body 2 includes main part 20, inclined plane 21, embedding part 22, inclined plane 21 butt in fixed part 12 and will the tip of fixed part 12 extrudes into second clamping part 123, simultaneously embedding part 22 is fixed to be embedded in fixed orifices 122, main part 20 ends outside fixed orifices 122.

Further, the supporting portion 11 also defines a mounting hole 110 for accommodating the main body 20, and the diameter of the mounting hole 110 is larger than that of the fixing hole 122.

Further, the bottom 13 is further provided with a positioning hole 100, and the center lines of the mounting hole 110, the fixing hole 122 and the positioning hole 100 coincide.

In this embodiment, the nut case 1 has a hollow structure such that the expansion portion 121 defines the fixing hole 122, and the supporting portion 11 further defines a mounting hole 110 for receiving the main body 20. The expansion 121 has the ability to deform so that the inclined surface 21 abuts against the fixing portion 12 and can press the end of the fixing portion 12 into the second clamping portion 123. The positioning hole 100 is used for allowing the screw 5 to pass through.

Further, the outer circumferential surface of the nut body 2 is provided with a cutting groove 23 that prevents the fitting portion 22 from rotating in the fixing hole 122.

Further, the slot 23 extends from a first end 25 to a second end 26 of the nut body 2.

Further, the nut body 2 is further provided with a threaded hole 24 penetrating the first end 25 and the second end 26.

Further, the insertion portion 22 is fixedly connected to the main body 20 through the inclined surface 21, and a cross-sectional diameter of the insertion portion 22 is smaller than a cross-sectional diameter of the main body 20.

When the pull nut of the present invention is used for mounting a workpiece 3, as shown in fig. 4, the pull nut is first placed on one side of the workpiece 3 having a hole-like structure, a screw 5 matched with the nut body 2 of the pull nut is passed through the member 4 to be mounted and the workpiece 3 and then matched with the threaded hole 24 of the nut body 2 of the pull nut, the screw 5 and the nut body 2 form a fixed connection by means of screw-thread matching, the nut body 2 moves upward along the screw 5 by passing through the fixing hole 122, (the nut body 2 can only move in the axial direction of the screw 5 because of being unable to rotate), at this time, the inclined surface 21 of the nut body 2 starts to abut against the fixing portion 12, the end of the fixing portion 12 is squeezed to form a second clamping portion 123, at this time, the second clamping portion 123 and the first clamping portion 120 clamp both sides of the workpiece 3, and then the nut sleeve body 1 and the workpiece 3 are fixedly mounted, then treat behind the screw tight screw 5 that installation component 4 just can be stable install on work piece 3, use the utility model discloses an installation component need not be with the help of the installation that the instrument just can be convenient during, bring the convenience for the user. Meanwhile, the embedding part 22 is fixedly embedded into the fixing hole 122, so that on one hand, the nut body 2 is fixed in the fixing hole 122, and the fastening of the screw 5 is facilitated; on the other hand, the embedding part 22 fills the fixing hole 122, so that the embedding part 22 supports the hole-shaped structure of the workpiece 3 for mounting the nut sleeve body 1, the hole-shaped structure of the workpiece 3 and the deformation resistance of the fixing hole 122 are improved, the fixing force between the nut sleeve body 1 and the workpiece 3 is increased, the nut sleeve body 1 is prevented from easily falling off from the workpiece 3, and the problem of fixing failure of the workpiece 3 is prevented.

Of course, the present invention can also have other various embodiments, and based on the embodiments, those skilled in the art can obtain other embodiments without any creative work, and all of them belong to the protection scope of the present invention.
